How to Use this Manual

Many people read their owner’s manual from beginning to end when they first receive their new vehicle. If you do this, it will help you learn about the features and controls for your vehicle. In this manual, you’ll find that pictures and words work together to explain things quickly.

Safety Warnings and Symbols

You will find a number of safety cautions in this book.

We use a box and the word CAUTION to tell you about things that could hurt you if you were to ignore the warning.

CAUTION:

These mean there is something that could hurt you or other people.

In the caution area, we tell you what the hazard is.

Then we tell you what to do to help avoid or reduce the hazard. Please read these cautions. If you don’t, you or others could be hurt.

You will also find a circle with a slash through it in this book. This safety symbol means “Don’t,”

“Don’t do this” or “Don’t let this happen.”

iii

Vehicle Damage Warnings

Also, in this book you will find these notices:

NOTICE:

These mean there is something that could damage your vehicle.

In the notice area, we tell you about something that can damage your vehicle. Many times, this damage would not be covered by your warranty, and it could be costly.

But the notice will tell you what to do to help avoid the damage.

When you read other manuals, you might see

CAUTION and NOTICE warnings in different colors or in different words.

You’ll also see warning labels on your vehicle.

They use the same words, CAUTION or NOTICE.

Vehicle Symbols

Your vehicle may be equipped with components and labels that use symbols instead of text. Symbols, used on your vehicle, are shown along with the text describing the operation or information relating to a specific component, control, message, gage or indicator.

If you need help figuring out a specific name of a component, gage or indicator reference the following topics in the Index:

D “Engine Compartment Overview”

D “Instrument Panel”

D “Comfort Controls”

D “Audio Systems”

Also see “Warning Lights and Gages” in the Index.

Seats and Seat Controls

This section tells you about the seats - how to adjust them, and fold them up and down. It also tells you about reclining front seatbacks and head restraints.

Manual Front Seat

CAUTION:

You can lose control of the vehicle if you try to adjust a manual driver’s seat while the vehicle is moving. The sudden movement could startle and confuse you, or make you push a pedal when you don’t want to. Adjust the driver’s seat only when the vehicle is not moving.

If your vehicle has a manual bucket or a split bench seat, you can adjust it with this lever located at the front of the seat.

Lift the lever to unlock the seat. Using your body, slide the seat to where you want it and release the lever. Try to move the seat with your body to make sure the seat is locked into place.

1-2

Manual Cushion Tilt (If Equipped)

Manual Lumbar Control (If Equipped)

If your vehicle has a lumbar adjustment, the knob is located on the outboard side of the seat cushion.

If your vehicle has this feature, you can raise or lower the front of the driver’s or passenger’s seat with this lever located at the inside edge of the seat. To raise or lower the front of the seat, move the lever up or down in a continuous motion until the cushion reaches the desired height.

To increase or decrease support, turn the knob toward the front or rear of the vehicle. Operating effort can be reduced if you lean forward slightly while turning the knob.

1-3

Power Seat(s) (If Equipped)

If your vehicle has a power seat, you can adjust it with these controls located on the outboard sides of the seats.

D Raise or lower the front of the seat cushion by raising or lowering the forward edge of the horizontal control.

D Move the seat forward or rearward by moving the whole horizontal control forward or rearward.

D Raise or lower the rear of the seat cushion by raising or lowering the rear edge of the horizontal control.

D Moving the whole horizontal control up or down raises or lowers the entire seat cushion.

If your vehicle has power reclining seats, you can use the vertical control to adjust the angle of the seatback.

Move the reclining front seatback rearward or forward by moving the control toward the rear or the front of the vehicle. See “Reclining Seatbacks” in the Index for further information.

1-4

Power Lumbar Control (If Equipped)

If your vehicle has this feature, the four way control is located on the outboard side of the seat.

Memory Seat (If Equipped)

If your vehicle has this feature, the buttons used to program and recall the driver’s seat and recliner position are located on the driver’s door trim panel.

To increase or decrease support, press and hold the front or rear of the control. Let go of the control when the lower seatback reaches the desired level of support.

You can also reshape the side wing area of the lower seatback for more lateral support. To increase or decrease support, press and hold the top or bottom of the control. Let go of the control when the lower seatback reaches the desired level of support.

It does not store the lumbar or back support positions.

To program the memory seat, do the following:

1. Adjust the driver’s seat to the desired position.

2. Then press the SET button and, within five seconds, press one of the two numbered buttons on the memory control.

To recall your setting, put the vehicle in PARK (P) and press the number you chose.

To program the seat position for a second driver, follow the preceding steps, but press the other number on the memory control.

1-5

Heated Front Seats (If Equipped)

If your vehicle has this feature, the button used to control the driver’s heated seat is located on the driver’s door panel. The button used to control the passenger’s heated seat is located on the passenger’s door panel.

Reclining Seatbacks

To activate the heated seats, press the button once for the HI heat setting. Press the button again for the LO heat setting. To turn off the heated seats, press the button a third time. An indicator light will illuminate for each heat setting anytime the heated seats are operating.

The ignition must be in RUN for them to operate.

The heated front seats will be canceled after the ignition is turned to OFF. If you still want to use the heated front seat feature after you restart your vehicle, you will need to press the heated seat button again.

To adjust the front seatback, lift the manual lever located on the outboard side of the seat. Release the lever to lock the seatback where you want it. Lift the lever again without pushing on the seatback and the seatback will go to an upright position.

If your vehicle has power seats with a power recliner, see “Power Seats” in the Index for further information on how to operate the reclining seatback feature.

1-6

But don’t have a seatback reclined if your vehicle is moving.

CAUTION:

Sitting in a reclined position when your vehicle is in motion can be dangerous. Even if you buckle up, your safety belts can’t do their job when you’re reclined like this.

The shoulder belt can’t do its job. In a crash, you could go into it, receiving neck or other injuries.

The lap belt can’t do its job either. In a crash the belt could go up over your abdomen. The belt forces would be there, not at your pelvic bones.

This could cause serious internal injuries.

For proper protection when the vehicle is in motion, have the seatback upright. Then sit well back in the seat and wear your safety belt properly.

1-7

Head Restraints

Slide the head restraint up or down so that the top of the restraint is closest to the top of your head. This position reduces the chance of a neck injury in a crash.

On some models, the head restraints tilt forward and rearward also.

The rear seat head restraints in your vehicle may be adjustable. They work the same as the front seat head restraints, except they do not tilt forward or rearward.

Rear Seats

60/40 Split Bench Seat

Tahoe/Yukon: The rear seat may have a 60/40 split seat which may be folded down to give you more cargo space.

Suburban/Yukon XL: The second row rear seat of

Suburban/Yukon XL models may have a 60/40 split seat. Either side of the rear seat may be folded down to provide more cargo space.

1-8

Folding the Seatbacks

CAUTION:

If the seatback isn’t locked, it could move forward in a sudden stop or crash. That could cause injury to the person sitting there. Always press rearward on the seatback to be sure it is locked.

On all models with 60/40 split bench seats, you must insert the center occupant lap belt latch plate into the loop provided, on the underside of the folded forward seat cushion, before folding the rear seat back down on the driver’s side.

You may have to adjust the location of the latch plate on the webbing so that it reaches the loop. Stowing in this loop will reduce the chances of damaging and soiling the belt. Remember to remove the latch plate from the loop before the seat is returned to the passenger position.

On Suburban/Yukon XL insert the two buckles into the retainer in the seatback, before folding the rear seat on the driver’s side. The buckles will be out of the way when the seat is folded and will be available for passengers to use when the seat is returned to the passenger position. Also, make sure that nothing is under or in front of the seat and that the head restraints are completely lowered.

On Tahoe/Yukon models the rear seatbacks may be equipped with rearward folding head restraints. When the seatback is being folded down, the head restraint will automatically fold rearward to allow a flat load floor for cargo or entry to the third row seat (if equipped).

1-9

To fold, pull up on the strap loop at the rear of the seat cushion. Then, pull the seat cushion up an fold it forward.

After folding the seat cushion fully forward, pull the seatback forward and fold the seatback down until it is flat. If the seatback cannot fold flat because it interferes with the cushion, try moving the seat forward and/or bring the front seatback more upright. On the passenger side of the Suburban/Yukon XL models, the lever at the base of the seat must be turned rearward to release the seatback.

To create a load floor release the panels from the seatback by pushing forward on the latch. Then fold the panels back to cover the rear seat footwell area.

To return the seat to the passenger position on a

Suburban/Yukon XL do the following:

1. Lift the floor load panels and latch them into the seatback.

2. Lift the seatback up and push rearward all the way.

3. Lower the seat cushion until it latches into position.

4. Pull forward on the seatback and up on the seat cushion to make sure the seat is securely in place.

1-10

Make sure that the buckles on the driver’s side seatback are accessible to the outboard and center occupant and are not under the seat cushions.

On Tahoe/Yukon models make sure the head restraints are returned to the upright position.

Bucket Seats (Suburban/Yukon XL

Second Row)

If your vehicle has bucket seats, the seatbacks can be reclined and the seats can be folded to give you more cargo room.

Reclining the Seatbacks

On the Suburban/Yukon XL models with bucket seats, the seatbacks can be reclined. To adjust the seatback do the following:

1. Pull forward the lever located at the base of the back.

2. Release the lever to lock the seatback where you want it. If you pull the lever without pushing on the seatback, the seatback will go to an upright position.

Folding the Seatbacks

CAUTION:

If the seatback isn’t locked, it could move forward in a sudden stop or crash. That could cause injury to the person sitting there. Always press rearward on the seatback to be sure it is locked.

The seatbacks on the bucket seats may be folded forward to give you more cargo space.

In order to fold the back of a bucket seat into a horizontal load floor, the back must be in its upright position, and not reclined.

1-11

CAUTION:

If a head restraint is not installed on the seatback or stored in the vehicle properly, it could be thrown about the vehicle in a crash or sudden maneuver.

People in the vehicle could be injured. Remove the head restraints only when you need to fold the seat, and be sure that the head restraints are stored securely in the space provided in the folded up seat cushion. When the seat is returned to the passenger position, be sure the head restraints are installed properly.

On Suburban/Yukon XL models with rear bucket seats, the head restraints need to be removed in order to fold the rear seats. To do this follow these directions:

1. Lift the head restraints up until they stop.

2. Press in the button on the side of the head restraint guide cap and lift up on the head restraint.

3. Do the same for the other cap.

The head restraint can be removed and stored in the space provided in the folded up seat cushion.

1-12

To fold the seatbacks on the bucket seats, do the following:

1. Pull up on the strap loop located at the rear of the seat cushion and pull the seat cushion up. Then fold it forward.

2. Push the seatback release lever rearward and pull the seatback forward.

Then fold it until it is flat.

If the seatback cannot fold flat because it interferes with the cushion, try moving the front seat forward and/or bringing the front seatback more upright.

Once the seatbacks are folded down, the rear seat footwell area will be exposed and will have to be covered by the load floor panel. To create a load floor, do the following:

50/50 Split Bench Seat (Third Row)

If your vehicle has a 50/50 split bench, the seatback(s) can be folded and the entire seat(s) tilted or removed from the vehicles.

Folding the Seatbacks

1. Release the panels from the seatbacks by pushing forward on the latches.

2. Then fold the panels back to cover the rear seat footwell area.

If you have removed the head restraints to fold the rear bucket seat, be sure to reinstall them on the seatback after it has been returned to the normal seating position.

CAUTION:

If the seatback isn’t locked, it could move forward in a sudden stop or crash. That could cause injury to the person sitting there. Always press rearward on the seatback to be sure it is locked.

To fold the seatbacks do the following:

D Pull up on the release lever, labeled 1, located on the rear of the seatback, and push the seatback forward.

D To return the seat to the passenger position, pull up on the release lever labeled 1 and then pull up on the seatback until the seatback locks into the upright position.

Safety Belts: They’re for Everyone

This part of the manual tells you how to use safety belts properly. It also tells you some things you should not do with safety belts.

And it explains the air bag system.

CAUTION:

Don’t let anyone ride where he or she can’t wear a safety belt properly. If you are in a crash and you’re not wearing a safety belt, your injuries can be much worse. You can hit things inside the vehicle or be ejected from it. You can be seriously injured or killed. In the same crash, you might not be if you are buckled up. Always fasten your safety belt, and check that your passengers’ belts are fastened properly too.

1-22

CAUTION:

It is extremely dangerous to ride in a cargo area, inside or outside of a vehicle. In a collision, people riding in these areas are more likely to be seriously injured or killed. Do not allow people to ride in any area of your vehicle that is not equipped with seats and safety belts. Be sure everyone in your vehicle is in a seat and using a safety belt properly.

Your vehicle has a light that comes on as a reminder to buckle up. See “Safety

Belt Reminder Light” in the Index.

In most states and Canadian provinces, the law says to wear safety belts. Here’s why: They work.

You never know if you’ll be in a crash. If you do have a crash, you don’t know if it will be a bad one.

A few crashes are mild, and some crashes can be so serious that even buckled up a person wouldn’t survive.

But most crashes are in between. In many of them, people who buckle up can survive and sometimes walk away. Without belts they could have been badly hurt or killed.

After more than 30 years of safety belts in vehicles, the facts are clear. In most crashes buckling up does matter ... a lot!

1-23

Why Safety Belts Work

When you ride in or on anything, you go as fast as it goes.

Take the simplest vehicle. Suppose it’s just a seat on wheels.

1-24

Put someone on it.

Get it up to speed. Then stop the vehicle. The rider doesn’t stop.

The person keeps going until stopped by something.

In a real vehicle, it could be the windshield ...

1-25

or the instrument panel ...

1-26

or the safety belts!

With safety belts, you slow down as the vehicle does.

You get more time to stop. You stop over more distance, and your strongest bones take the forces. That’s why safety belts make such good sense.

Here Are Questions Many People Ask

About Safety Belts

--

and the Answers

Q:

Won’t I be trapped in the vehicle after an accident if I’m wearing a safety belt?

A:

You could be - whether you’re wearing a safety belt or not. But you can unbuckle a safety belt, even if you’re upside down. And your chance of being conscious during and after an accident, so you can unbuckle and get out, is much greater if you are belted.

Q:

If my vehicle has air bags, why should I have to wear safety belts?

A:

Air bags are in many vehicles today and will be in most of them in the future. But they are supplemental systems only; so they work with safety belts - not instead of them. Every air bag system ever offered for sale has required the use of safety belts. Even if you’re in a vehicle that has air bags, you still have to buckle up to get the most protection. That’s true not only in frontal collisions, but especially in side and other collisions.

Q:

If I’m a good driver, and I never drive far from home, why should I wear safety belts?

A:

You may be an excellent driver, but if you’re in an accident - even one that isn’t your fault - you and your passengers can be hurt. Being a good driver doesn’t protect you from things beyond your control, such as bad drivers.

Most accidents occur within 25 miles (40 km) of home. And the greatest number of serious injuries and deaths occur at speeds of less than

40 mph (65 km/h).

Safety belts are for everyone.

How to Wear Safety Belts Properly

Adults

This part is only for people of adult size.

Be aware that there are special things to know about safety belts and children. And there are different rules for smaller children and babies. If a child will be riding in your vehicle, see the part of this manual called “Children.”

Follow those rules for everyone’s protection.

First, you’ll want to know which restraint systems your vehicle has.

We’ll start with the driver position.

Driver Position

This part describes the driver’s restraint system.

Lap-Shoulder Belt

The driver has a lap shoulder belt. Here’s how to wear it properly.

1. Close and lock the door.

2. Adjust the seat so you can sit up straight. To see how, see “Seats” in the Index.

3. Pick up the latch plate and pull the belt across you.

Don’t let it get twisted.

The shoulder belt may lock if you pull the belt across you very quickly. If this happens, let the belt go back slightly to unlock it. Then pull the belt across you more slowly.

1-28

4. Push the latch plate into the buckle until it clicks.

Pull up on the latch plate to make sure it is secure.

If the belt isn’t long enough, see “Safety Belt

Extender” at the end of this section.

Make sure the release button on the buckle is positioned so you would be able to unbuckle the safety belt quickly if you ever had to.

5. To make the lap part tight, pull down on the buckle end of the belt as you pull up on the shoulder belt.

The lap part of the belt should be worn low and snug on the hips, just touching the thighs. In a crash, this applies force to the strong pelvic bones. And you’d be less likely to slide under the lap belt. If you slid under it, the belt would apply force at your abdomen. This could cause serious or even fatal injuries. The shoulder belt should go over the shoulder and across the chest. These parts of the body are best able to take belt restraining forces.

The safety belt locks if there’s a sudden stop or a crash.

1-29

Q:

What’s wrong with this?

CAUTION:

You can be seriously hurt if your shoulder belt is too loose. In a crash, you would move forward too much, which could increase injury. The shoulder belt should fit against your body.

A:

The shoulder belt is too loose. It won’t give nearly as much protection this way.

1-30

Q:

What’s wrong with this?

CAUTION:

You can be seriously injured if your belt is buckled in the wrong place like this. In a crash, the belt would go up over your abdomen. The belt forces would be there, not at the pelvic bones. This could cause serious internal injuries. Always buckle your belt into the buckle nearest you.

A:

The belt is buckled in the wrong place.

1-31

Q:

What’s wrong with this?

CAUTION:

You can be seriously injured if your belt goes over an armrest like this. The belt would be much too high. In a crash, you can slide under the belt.

The belt force would then be applied at the abdomen, not at the pelvic bones, and that could cause serious or fatal injuries. Be sure the belt goes under the armrests.

A:

The belt is over an armrest.

1-32

Q:

What’s wrong with this?

A:

The shoulder belt is worn under the arm. It should be worn over the shoulder at all times.

CAUTION:

You can be seriously injured if you wear the shoulder belt under your arm. In a crash, your body would move too far forward, which would increase the chance of head and neck injury.

Also, the belt would apply too much force to the ribs, which aren’t as strong as shoulder bones.

You could also severely injure internal organs like your liver or spleen.

1-33

Q:

What’s wrong with this?

CAUTION:

You can be seriously injured by a twisted belt. In a crash, you wouldn’t have the full width of the belt to spread impact forces. If a belt is twisted, make it straight so it can work properly, or ask your dealer to fix it.

A:

The belt is twisted across the body.

1-34

Safety Belt Use During Pregnancy

Safety belts work for everyone, including pregnant women. Like all occupants, they are more likely to be seriously injured if they don’t wear safety belts.

To unlatch the belt, just push the button on the buckle.

The belt should go back out of the way.

Before you close the door, be sure the belt is out of the way. If you slam the door on it, you can damage both the belt and your vehicle.

A pregnant woman should wear a lap shoulder belt, and the lap portion should be worn as low as possible, below the rounding, throughout the pregnancy.

1-35

The best way to protect the fetus is to protect the mother. When a safety belt is worn properly, it’s more likely that the fetus won’t be hurt in a crash. For pregnant women, as for anyone, the key to making safety belts effective is wearing them properly.

Right Front Passenger Position

To learn how to wear the right front passenger’s safety belt properly, see “Driver Position” earlier in this section.

The right front passenger’s safety belt works the same way as the driver’s safety belt - except for one thing.

If you ever pull the shoulder portion of the belt out all the way, you will engage the child restraint locking feature. If this happens, just let the belt go back all the way and start again.

Air Bag Systems

This part explains the frontal and side impact air bag systems.

Your vehicle has four air bags - a frontal air bag for the driver, another frontal air bag for the right front passenger, a side impact air bag for the driver, and another side impact air bag for the right front passenger.

Frontal air bags are designed to help reduce the risk of injury from the force of an inflating frontal air bag. But these air bags must inflate very quickly to do their job and comply with federal regulations.

1-36

Here are the most important things to know about the air bag systems:

CAUTION:

You can be severely injured or killed in a crash if you aren’t wearing your safety belt - even if you have air bags. Wearing your safety belt during a crash helps reduce your chance of hitting things inside the vehicle or being ejected from it. Air bags are designed to work with safety belts but don’t replace them.

Frontal air bags for the driver and right front passenger are designed to work only in moderate to severe crashes where the front of your vehicle hits something. They aren’t designed to inflate at all in rollover, rear or low speed frontal crashes, or in many side crashes. And, for some unrestrained occupants, frontal air bags may provide less protection in frontal crashes than more forceful air bags have provided in the past.

CAUTION: (Continued)

CAUTION: (Continued)

The side impact air bags for the driver and right front passenger are designed to inflate only in moderate to severe crashes where something hits the side of your vehicle. They aren’t designed to inflate in frontal, in rollover or in rear crashes.

Everyone in your vehicle should wear a safety belt properly - whether or not there’s an air bag for that person.

CAUTION:

Both frontal and side impact air bags inflate with great force, faster than the blink of an eye. If you’re too close to an inflating air bag, as you would be if you were leaning forward, it could seriously injure you. Safety belts help keep you in position for air bag inflation before and during a crash. Always wear your safety belt, even with frontal air bags. The driver should sit as far back as possible while still maintaining control of the vehicle. Front occupants should not lean on or sleep against the door.

1-37

CAUTION:

Anyone who is up against, or very close to, any air bag when it inflates can be seriously injured or killed. Air bags plus lap shoulder belts offer the best protection for adults, but not for young children and infants. Neither the vehicle’s safety belt system nor its air bag system is designed for them. Young children and infants need the protection that a child restraint system can provide. Always secure children properly in your vehicle. To read how, see the part of this manual called “Children.”

There is an air bag readiness light on the instrument panel, which shows the air bag symbol.

The system checks the air bag electrical system for malfunctions. The light tells you if there is an electrical problem. See “Air Bag Readiness Light” in the Index for more information.

1-38

How the Air Bag Systems Work

Where are the air bags?

The driver’s frontal air bag is in the middle of the steering wheel.

The right front passenger’s frontal air bag is in the instrument panel on the passenger’s side.

The driver’s side impact air bag is in the side of the driver’s seatback closest to the door.

1-39

The right front passenger’s side impact air bag is in the side of the passenger’s seatback closest to the door.

CAUTION:

If something is between an occupant and an air bag, the bag might not inflate properly or it might force the object into that person causing severe injury or even death. The path of an inflating air bag must be kept clear. Don’t put anything between an occupant and an air bag, and don’t attach or put anything on the steering wheel hub or on or near any other air bag covering. Don’t let seat covers block the inflation path of a side impact air bag.

1-40

When should an air bag inflate?

The driver’s and right front passenger’s frontal air bags are designed to inflate in moderate to severe frontal or near frontal crashes. But they are designed to inflate only if the impact speed is above the system’s designed

“threshold level.”

If your vehicle goes straight into a wall that doesn’t move or deform, the threshold level is about 9 to

16 mph (14 to 26 km/h). The threshold level can vary, however, with specific vehicle design, so that it can be somewhat above or below this range.

If your vehicle strikes something that will move or deform, such as a parked car, the threshold level will be higher. The driver’s and right front passenger’s frontal air bags are not designed to inflate in rollovers, rear impacts, or in many side impacts because inflation would not help the occupant.

The side impact air bags are designed to inflate in moderate to severe side crashes. A side impact air bag will inflate if the crash severity is above the system’s designed “threshold level.” The threshold level can vary with specific vehicle design. Side impact air bags are not designed to inflate in frontal or near frontal impacts, rollovers or rear impacts, because inflation would not help the occupant. A side impact air bag will only deploy on the side of the vehicle that is struck.

In any particular crash, no one can say whether an air bag should have inflated simply because of the damage to a vehicle or because of what the repair costs were.

For frontal air bags, inflation is determined by the angle of the impact and how quickly the vehicle slows down in frontal and near frontal impacts. For side impact air bags, inflation is determined by the location and severity of the impact.

The air bag system is designed to work properly under a wide range of conditions, including off road usage.

Observe safe driving speeds, especially on rough terrain.

As always, wear your safety belt. See “Off

Driving” in the Index for more tips on off

Road

road driving.

What makes an air bag inflate?

In an impact of sufficient severity, the air bag sensing system detects that the vehicle is in a crash. For both frontal and side impact air bags, the sensing system triggers a release of gas from the inflator, which inflates the air bag. The inflator, air bag and related hardware are all part of the air bag modules inside the steering wheel, instrument panel and the side of the front seatbacks closest to the door.

1-41

How does an air bag restrain?

In moderate to severe frontal or near frontal collisions, even belted occupants can contact the steering wheel or the instrument panel. In moderate to severe side collisions, even belted occupants can contact the inside of the vehicle. The air bag supplements the protection provided by safety belts. Air bags distribute the force of the impact more evenly over the occupant’s upper body, stopping the occupant more gradually. But the frontal air bags would not help you in many types of collisions, including rollovers, rear impacts, and many side impacts, primarily because an occupant’s motion is not toward the air bag. Side impact air bags would not help you in many types of collisions, including frontal or near frontal collisions, rollovers, and rear impacts, primarily because an occupant’s motion is not toward those air bags. Air bags should never be regarded as anything more than a supplement to safety belts, and then only in moderate to severe frontal or near frontal collisions for the driver’s and right front passenger’s frontal air bags, and only in moderate to severe side collisions for the driver’s and right front passenger’s side impact air bags.

What will you see after an air bag inflates?

After an air bag inflates, it quickly deflates, so quickly that some people may not even realize the air bag inflated. Some components of the air bag module - the steering wheel hub for the driver’s air bag, the instrument panel for the right front passenger’s bag, the side of the seatback closest to the door for the driver and right front passenger’s side impact air bags - will be hot for a short time. The parts of the bag that come into contact with you may be warm, but not too hot to touch.

There will be some smoke and dust coming from the vents in the deflated air bags. Air bag inflation doesn’t prevent the driver from seeing or being able to steer the vehicle, nor does it stop people from leaving the vehicle.

CAUTION:

When an air bag inflates, there is dust in the air.

This dust could cause breathing problems for people with a history of asthma or other breathing trouble. To avoid this, everyone in the vehicle should get out as soon as it is safe to do so.

If you have breathing problems but can’t get out of the vehicle after an air bag inflates, then get fresh air by opening a window or a door.

1-42

In many crashes severe enough to inflate an air bag, windshields are broken by vehicle deformation.

Additional windshield breakage may also occur from the right front passenger air bag.

D Air bags are designed to inflate only once. After an air bag inflates, you’ll need some new parts for your air bag system. If you don’t get them, the air bag system won’t be there to help protect you in another crash. A new system will include air bag modules and possibly other parts. The service manual for your vehicle covers the need to replace other parts.

D Your vehicle is equipped with a crash sensing and diagnostic module, which records information about the frontal air bag system. The module records information about the readiness of the system, when the system commands air bag inflation and driver’s safety belt usage at deployment. The module also records speed, engine rpm, brake and throttle data.

D Let only qualified technicians work on your air bag systems. Improper service can mean that an air bag system won’t work properly. See your dealer for service.

NOTICE:

If you damage the covering for the driver’s or the right front passenger’s air bag, or the air bag covering on the driver’s and right front passenger’s seatback, the bag may not work properly. You may have to replace the air bag module in the steering wheel, both the air bag module and the instrument panel for the right front passenger’s air bag, or both the air bag module and seatback for the driver’s and right front passenger’s side impact air bag. Do not open or break the air bag coverings.

1-43

Servicing Your Air Bag-Equipped Vehicle

Air bags affect how your vehicle should be serviced.

There are parts of the air bag systems in several places around your vehicle. Your dealer and the service manual have information about servicing your vehicle and the air bag systems. To purchase a service manual, see

“Service and Owner Publications” in the Index.

Adding Equipment to Your Air

Bag-Equipped Vehicle

Q:

If I add a push bumper or bicycle rack to the front of my vehicle, will it keep the air bags from working properly?

A:

As long as the push bumper or bicycle rack is attached to your vehicle so that the vehicle’s basic structure isn’t changed, it’s not likely to keep the air bags from working properly in a crash.

CAUTION:

For up to 10 minutes after the ignition key is turned off and the battery is disconnected, an air bag can still inflate during improper service. You can be injured if you are close to an air bag when it inflates. Avoid yellow connectors. They are probably part of the air bag systems. Be sure to follow proper service procedures, and make sure the person performing work for you is qualified to do so.

The air bag systems do not need regular maintenance.

1-44

Q:

Is there anything I might add to the front or sides of the vehicle that could keep the air bags from working properly?

A:

Yes. If you add things that change your vehicle’s frame, bumper system, front end or side sheet metal or height, they may keep the air bag system from working properly. Also, the air bag system may not work properly if you relocate any of the air bag sensors. If you have any questions about this, you should contact Customer Assistance before you modify your vehicle. The phone numbers and addresses for Customer Assistance are in Step Two of the Customer Satisfaction

Procedure in this manual. See “Customer

Satisfaction Procedure” in the Index.

Q:

What if I add a snow plow? Will it keep the air bags from working properly?

A:

We’ve designed our air bag systems to work properly under a wide range of conditions, including snow plowing with vehicles equipped with the optional Snow Plow Prep Package

(RPO VYU). But don’t change or defeat the snow plow’s “tripping mechanism.” If you do, it can damage your snow plow and your vehicle, and it may cause an air bag inflation.

1-45

Center Passenger Position

Lap Belt

If your vehicle has front and rear bench seats, someone can sit in the center positions.

When you sit in a center seating position, you have a lap safety belt, which has no retractor. To make the belt longer, tilt the latch plate and pull it along the belt.

1-46

To make the belt shorter, pull its free end as shown until the belt is snug.

Buckle, position and release it the same way as the lap part of a lap shoulder belt. If the belt isn’t long enough, see “Safety Belt Extender” at the end of this section.

Make sure the release button on the buckle is positioned so you would be able to unbuckle the safety belt quickly if you ever had to.

Rear Seat Passengers

It’s very important for rear seat passengers to buckle up!

Accident statistics show that unbelted people in the rear seat are hurt more often in crashes than those who are wearing safety belts.

Rear passengers who aren’t safety belted can be thrown out of the vehicle in a crash. And they can strike others in the vehicle who are wearing safety belts.

1-47

Rear Seat Outside Passenger Positions

Lap

-

Shoulder Belt

The positions next to the windows have lap shoulder belts. Here’s how to wear one properly.

1. Pick up the latch plate and pull the belt across you.

Don’t let it get twisted.

1-48

2. Push the latch plate into the buckle until it clicks.

Pull up on the latch plate to make sure it is secure.

When the shoulder belt is pulled out all the way, it will lock. If it does, let it go back all the way and start again.

If the belt is not long enough, see “Safety Belt

Extender” at the end of this section.

Make sure the release button on the buckle is positioned so you would be able to unbuckle the safety belt quickly if you ever had to.

3. To make the lap part tight, pull down on the buckle end of the belt as you pull up on the shoulder part.

1-49

CAUTION:

You can be seriously hurt if your shoulder belt is too loose. In a crash, you would move forward too much, which could increase injury. The shoulder belt should fit against your body.

The lap part of the belt should be worn low and snug on the hips, just touching the thighs. In a crash, this applies force to the strong pelvic bones. And you’d be less likely to slide under the lap belt. If you slid under it, the belt would apply force at your abdomen. This could cause serious or even fatal injuries. The shoulder belt should go over the shoulder and across the chest. These parts of the body are best able to take belt restraining forces.

The safety belt locks if there’s a sudden stop or a crash.

1-50

To unlatch the belt, just push the button on the buckle.

Rear Safety Belt Comfort Guides for

Children and Small Adults

Rear shoulder belt comfort guides will provide added safety belt comfort for older children who have outgrown booster seats and for small adults. When installed on a shoulder belt, the comfort guide better positions the belt away from the neck and head.

There is one guide for each outside passenger position in the rear seats. To provide added safety belt comfort for children who have outgrown child restraints and for smaller adults, the comfort guides may be installed on the shoulder belts. Here’s how to install a comfort guide and use the safety belt:

Second Row Seat

1-51

Third Row Seat

1. For the second row, remove the guide from its storage clip on the trim panel near the side of the seatback. For the third row, remove the guide from its storage clip on the side of the seatback.

2. Place the guide over the belt and insert the two edges of the belt into the slots of the guide.

1-52

3. Be sure that the belt is not twisted and it lies flat. The guide must be on top of the belt.

Second Row Seat

1-53

Third Row Seat

4. Buckle, position and release the safety belt as described in “Rear Seat Outside Passenger Positions” earlier in this section. Make sure that the shoulder belt crosses the shoulder.

To remove and store the comfort guides, squeeze the belt edges together so that you can take them out of the guides. Make sure you remove the comfort guide from the belt before you fold a rear seat down or use an easy entry seat, if your vehicle has one.

1-54

Children

Everyone in a vehicle needs protection! This includes infants and all other children. Neither the distance traveled nor the age and size of the traveler changes the need, for everyone, to use safety restraints. In fact, the law in every state in the United States and in every

Canadian province says children up to some age must be restrained while in a vehicle.

Infants and Young Children

Every time infants and young children ride in vehicles, they should have the protection provided by the appropriate restraint. Young children should not use the vehicle’s safety belts, unless there is no other choice.

CAUTION:

People should never hold a baby in their arms while riding in a vehicle. A baby doesn’t weigh much - until a crash. During a crash a baby will become so heavy it is not possible to hold it. For example, in a crash at only 25 mph (40 km/h), a

12 lb. (5.5 kg) baby will suddenly become a

240 lb. (110 kg) force on a person’s arms. A baby should be secured in an appropriate restraint.

1-55

1-56

CAUTION:

Children who are up against, or very close to, any air bag when it inflates can be seriously injured or killed. Air bags plus lap shoulder belts offer outstanding protection for adults and older children, but not for young children and infants.

Neither the vehicle’s safety belt system nor its air bag system is designed for them. Young children and infants need the protection that a child restraint system can provide.

Q:

What are the different types of add on child restraints?

A:

Add on child restraints, which are purchased by the vehicle’s owner, are available in four basic types. Selection of a particular restraint should take into consideration not only the child’s weight, height and age but also whether or not the restraint will be compatible with the motor vehicle in which it will be used.

For most basic types of child restraints, there are many different models available. When purchasing a child restraint, be sure it is designed to be used in a motor vehicle. If it is, the restraint will have a label saying that it meets federal motor vehicle safety standards.

The restraint manufacturer’s instructions that come with the restraint state the weight and height limitations for a particular child restraint. In addition, there are many kinds of restraints available for children with special needs.

CAUTION:

Newborn infants need complete support, including support for the head and neck. This is necessary because a newborn infant’s neck is weak and its head weighs so much compared with the rest of its body. In a crash, an infant in a rear facing seat settles into the restraint, so the crash forces can be distributed across the strongest part of an infant’s body, the back and shoulders. Infants always should be secured in appropriate infant restraints.

1-57

CAUTION:

The body structure of a young child is quite unlike that of an adult or older child, for whom the safety belts are designed. A young child’s hip bones are still so small that the vehicle’s regular safety belt may not remain low on the hip bones, as it should. Instead, it may settle up around the child’s abdomen. In a crash, the belt would apply force on a body area that’s unprotected by any bony structure. This alone could cause serious or fatal injuries. Young children always should be secured in appropriate child restraints.

Restraint Systems for Children

An infant car bed (A), a special bed made for use in a motor vehicle, is an infant restraint system designed to restrain or position a child on a continuous flat surface.

Make sure that the infant’s head rests toward the center of the vehicle.

1-58

A rear facing infant seat (B) provides restraint with the seating surface against the back of the infant. The harness system holds the infant in place and, in a crash, acts to keep the infant positioned in the restraint.

A forward facing child seat (C E) provides restraint for the child’s body with the harness and also sometimes with surfaces such as T shaped or shelf like shields.

1-59

A booster seat (F G) is a child restraint designed to improve the fit of the vehicle’s safety belt system. Some booster seats have a shoulder belt positioner, and some high back booster seats have a five point harness. A booster seat can also help a child to see out the window.

Q:

How do child restraints work?

A:

A child restraint system is any device designed for use in a motor vehicle to restrain, seat, or position children. A built in child restraint system is a permanent part of the motor vehicle. An add on child restraint system is a portable one, which is purchased by the vehicle’s owner.

For many years, add on child restraints have used the adult belt system in the vehicle. To help reduce the chance of injury, the child also has to be secured within the restraint. The vehicle’s belt system secures the add on child restraint in the vehicle, and the add on child restraint’s harness system holds the child in place within the restraint.

One system, the three point harness, has straps that come down over each of the infant’s shoulders and buckle together at the crotch. The five point harness system has two shoulder straps, two hip straps and a crotch strap. A shield may take the place of hip straps. A T shaped shield has shoulder straps that are attached to a flat pad which rests low against the child’s body. A shelf or armrest type shield has straps that are attached to a wide, shelf like shield that swings up or to the side.

1-60

When choosing a child restraint, be sure the child restraint is designed to be used in a vehicle. If it is, it will have a label saying that it meets federal motor vehicle safety standards.

Then follow the instructions for the restraint. You may find these instructions on the restraint itself or in a booklet, or both. These restraints use the belt system in your vehicle, but the child also has to be secured within the restraint to help reduce the chance of personal injury.

When securing an add on child restraint, refer to the instructions that come with the restraint which may be on the restraint itself or in a booklet, or both, and to this manual. The child restraint instructions are important, so if they are not available, obtain a replacement copy from the manufacturer.

Where to Put the Restraint

Accident statistics show that children are safer if they are restrained in the rear rather than the front seat.

General Motors, therefore, recommends that child restraints be secured in a rear seat including an infant riding in a rear facing infant seat, a child riding in a forward facing child seat and an older child riding in a booster seat. Never put a rear facing child restraint in the right front passenger seat. Here’s why:

CAUTION:

A child in a rear facing child restraint can be seriously injured or killed if the right front passenger’s air bag inflates. This is because the back of the rear facing child restraint would be very close to the inflating air bag. Always secure a rear facing child restraint in a rear seat.

You may secure a forward facing child restraint in the right front seat, but before you do, always move the front passenger seat as far back as it will go. It’s better to secure the child restraint in a rear seat.

Wherever you install it, be sure to secure the child restraint properly.

Keep in mind that an unsecured child restraint can move around in a collision or sudden stop and injure people in the vehicle. Be sure to properly secure any child restraint in your vehicle - even when no child is in it.

1-61

Top Strap

Some child restraints have a top strap, or “top tether.”

It can help restrain the child restraint during a collision.

For it to work, a top strap must be properly anchored to the vehicle. Some top strap equipped child restraints are designed for use with or without the top strap being anchored. Others require the top strap always to be anchored. Be sure to read and follow the instructions for your child restraint. If yours requires that the top strap be anchored, don’t use the restraint unless it is anchored properly.

If the child restraint does not have a top strap, one can be obtained, in kit form, for many child restraints.

Ask the child restraint manufacturer whether or not a kit is available.

1-62

In Canada, the law requires that forward facing child restraints have a top strap, and that the strap be anchored. In the United States, some child restraints also have a top strap. If your child restraint has a top strap, it should be anchored.

Anchor the top strap to one of the following anchor points. Be sure to use an anchor point located on the same side of the vehicle as the seating position where the child restraint will be placed. If you have an adjustable head restraint, route the top strap under it.

Once you have the top strap anchored, you’ll be ready to secure the child restraint itself. Tighten the top strap when and as the child restraint manufacturer’s instructions say.

Tahoe/Suburban/Yukon/Yukon XL models without

rear seats: Top strap anchor loops are located at the bottom rear of the front seat cushion for the right front passenger’s position.

Suburban/Yukon XL Models without Rear Seats

Anchor the top strap to this bracket. Once you have the top strap anchored, you’ll be ready to secure the child restraint itself.

1-63

Tahoe/Suburban/Yukon/Yukon XL models with rear

seats: A child restraint with a top strap should only be used in the second or third row. Don’t use a child restraint with a top strap in the front seat because there’s no place to anchor the top strap.

An anchor loop bracket for a top strap is located at the bottom rear of the seat cushion for each seating position in the second row, and for the center seating position in the third row.

Suburban/Yukon XL Second Row Seat,

Bucket Seats Similar.

Lower Anchorages and Top Tethers for

Children (LATCH System) (If Equipped)

Your vehicle may have the LATCH system. If it does, you’ll find anchors (A) in the second row seats, where the seatbacks meets the seat cushions.

To assist you in locating the lower anchors for this child restraint system, each seating position with the LATCH system will have a visible metal anchorage point in the seat where the seatback meets the seat cushion.

In order to use the system, you need either a forward facing child restraint that has attaching points (B) at its base and a top tether anchor (C), or a rear facing child restraint that has attaching points (B), as shown here.

1-66

With this system, use the LATCH system instead of the vehicle’s safety belts to secure a child restraint.

CAUTION:

If a LATCH type child restraint isn’t attached to its anchorage points, the restraint won’t be able to protect a child sitting there. In a crash, the child could be seriously injured or killed. Make sure that a LATCH type child restraint is properly installed using the anchorage points, or use the vehicle’s safety belts to secure the restraint. See ”Securing a Child Restraint in a

Rear Outside Seat Position” in the Index for information on how to secure a child restraint in your vehicle using the vehicle’s safety belts.

1-67

Securing a Child Restraint Designed for the

LATCH System

1. Find the anchors for the seating position you want to use, where the bottom of the seatback meets the back of the seat cushion.

2. Put the child restraint on the seat.

3. Attach the anchor points on the child restraint to the anchors in the vehicle. The child restraint instructions will show you how.

4. If the child restraint is forward facing, attach the top strap to the top strap anchor. See “Top Strap” in the

Index. Tighten the top strap according to the child restraint instructions.

5. Push and pull the child restraint in different directions to be sure it is secure.

To remove the child restraint, simply unhook the top strap from the top tether anchor and then disconnect the anchor points.

Securing a Child Restraint in a Rear

Outside Seat Position

If your child restraint is equipped with the LATCH system, see “Lower Anchorages and Top Tethers for

Children (LATCH)” in the Index.

1-68

You’ll be using the lap shoulder belt. See the earlier part about the top strap if the child restraint has one.

Be sure to follow the instructions that came with the child restraint. Secure the child in the child restraint when and as the instructions say.

1. Put the restraint on the seat.

2. Pick up the latch plate, and run the lap and shoulder portions of the vehicle’s safety belt through or around the restraint. The child restraint instructions will show you how.

If the shoulder belt goes in front of the child’s face or neck, put it behind the child restraint.

3. Buckle the belt. Make sure the release button is positioned so you would be able to unbuckle the safety belt quickly if you ever had to.

1-69

4. Pull the rest of the shoulder belt all the way out of the retractor to set the lock.

5. To tighten the belt, feed the shoulder belt back into the retractor while you push down on the child restraint. If you’re using a forward facing child restraint, you may find it helpful to use your knee to push down on the child restraint as you tighten the belt.

6. Push and pull the child restraint in different directions to be sure it is secure.

To remove the child restraint, just unbuckle the vehicle’s safety belt and let it go back all the way. The safety belt will move freely again and be ready to work for an adult or larger child passenger.

Securing a Child Restraint in a

Center Rear Seat Position

You’ll be using the lap belt. Be sure to follow the instructions that came with the child restraint. Secure the child in the child restraint when and as the instructions say.

See the earlier part about the top strap if the child restraint has one.

1. Make the belt as long as possible by tilting the latch plate and pulling it along the belt.

2. Put the restraint on the seat.

3. Run the vehicle’s safety belt through or around the restraint. The child restraint instructions will show you how.

To remove the child restraint, just unbuckle the vehicle’s safety belt. It will be ready to work for an adult or larger child passenger.

Securing a Child Restraint in the Center

Front Seat Position

Securing a Child Restraint in the Right

Front Seat Position

Don’t use child restraints in this position. The restraints won’t work properly.

1-73

Your vehicle has a right front passenger air bag. Never put a rear facing child restraint in this seat. Here’s why:

CAUTION:

A child in a rear facing child restraint can be seriously injured or killed if the right front passenger’s air bag inflates. This is because the back of the rear facing child restraint would be very close to the inflating air bag. Always secure a rear facing child restraint in the rear seat.

Although a rear seat is a safer place, you can secure a forward facing child restraint in the right front seat.

You’ll be using the lap shoulder belt. See the earlier part about the top strap if the child restraint has one. Be sure to follow the instructions that came with the child restraint. Secure the child in the child restraint when and as the instructions say.

1. Because your vehicle has a right front passenger air bag, always move the seat as far back as it will go before securing a forward facing child restraint. See

“Seats” in the Index.

2. Put the restraint on the seat.

1-74

3. Pick up the latch plate, and run the lap and shoulder portions of the vehicle’s safety belt through or around the restraint. The child restraint instructions will show you how.

If the shoulder belt goes in front of the child’s face or neck, put it behind the child restraint.

4. Buckle the belt. Make sure the release button is positioned so you would be able to unbuckle the safety belt quickly if you ever had to.

5. Pull the rest of the shoulder belt all the way out of the retractor to set the lock.

6. To tighten the belt, feed the shoulder belt back into the retractor while you push down on the child restraint.

You may find it helpful to use your knee to push down on the child restraint as you tighten the belt.

7. Push and pull the child restraint in different directions to be sure it is secure.

To remove the child restraint, just unbuckle the vehicle’s safety belt and let it go back all the way. The safety belt will move freely again and be ready to work for an adult or larger child passenger.

1-75

Older Children

Older children who have outgrown booster seats should wear the vehicle’s safety belts.

If you have the choice, a child should sit next to a window so the child can wear a lap shoulder belt and get the additional restraint a shoulder belt can provide.

1-76

Q:

What is the proper way to wear safety belts?

A:

If possible, an older child should wear a lap shoulder belt and get the additional restraint a shoulder belt can provide. The shoulder belt should not cross the face or neck. The lap belt should fit snugly below the hips, just touching the top of the thighs. It should never be worn over the abdomen, which could cause severe or even fatal internal injuries in a crash.

Accident statistics show that children are safer if they are restrained in the rear seat.

In a crash, children who are not buckled up can strike other people who are buckled up, or can be thrown out of the vehicle. Older children need to use safety belts properly.

CAUTION:

Never do this.

Here two children are wearing the same belt. The belt can’t properly spread the impact forces. In a crash, the two children can be crushed together and seriously injured. A belt must be used by only one person at a time.

Q:

What if a child is wearing a lap shoulder belt, but the child is so small that the shoulder belt is very close to the child’s face or neck?

A:

Move the child toward the center of the vehicle, but be sure that the shoulder belt still is on the child’s shoulder, so that in a crash the child’s upper body would have the restraint that belts provide. If the child is sitting in a rear seat outside position, see

“Rear Safety Belt Comfort Guides” in the Index.

If the child is so small that the shoulder belt is still very close to the child’s face or neck, you might want to place the child in a seat that has a lap belt, if your vehicle has one.

1-77

1-78

CAUTION:

Never do this.

Here a child is sitting in a seat that has a lap shoulder belt, but the shoulder part is behind the child. If the child wears the belt in this way, in a crash the child might slide under the belt. The belt’s force would then be applied right on the child’s abdomen. That could cause serious or fatal injuries.

Wherever the child sits, the lap portion of the belt should be worn low and snug on the hips, just touching the child’s thighs. This applies belt force to the child’s pelvic bones in a crash.

Safety Belt Extender

If the vehicle’s safety belt will fasten around you, you should use it.

But if a safety belt isn’t long enough to fasten, your dealer will order you an extender. It’s free. When you go in to order it, take the heaviest coat you will wear, so the extender will be long enough for you. The extender will be just for you, and just for the seat in your vehicle that you choose. Don’t let someone else use it, and use it only for the seat it is made to fit. To wear it, just attach it to the regular safety belt.

Checking Your Restraint Systems

Now and then, make sure the safety belt reminder light and all your belts, buckles, latch plates, retractors and anchorages are working properly. Look for any other loose or damaged safety belt system parts. If you see anything that might keep a safety belt system from doing its job, have it repaired.

Torn or frayed safety belts may not protect you in a crash. They can rip apart under impact forces. If a belt is torn or frayed, get a new one right away.

Also look for any opened or broken air bag covers, and have them repaired or replaced. (The air bag system does not need regular maintenance.)

Replacing Restraint System Parts

After a Crash

If you’ve had a crash, do you need new belts or LATCH system parts?

After a very minor collision, nothing may be necessary.

But if the belts were stretched, as they would be if worn during a more severe crash, then you need new parts.

If the LATCH system was being used during a more severe crash, you may need new LATCH system parts.

If belts are cut or damaged, replace them. Collision damage also may mean you will need to have LATCH system, safety belt or seat parts repaired or replaced.

New parts and repairs may be necessary even if the belt or LATCH system wasn’t being used at the time of the collision.

If an air bag inflates, you’ll need to replace air bag system parts. See the part on the air bag system earlier in this section.

WINDOW LOCK is engaged. When the button is not engaged, the passenger’s power windows will operate.

2-3

Keys

CAUTION:

Leaving children in a vehicle with the ignition key is dangerous for many reasons. A child or others could be badly injured or even killed.

They could operate the power windows or other controls or even make the vehicle move. Don’t leave the keys in a vehicle with children.

2-4

Your vehicle has one double sided key for the ignition and all door locks as well as the spare tire hoist lock.

Your vehicle may also have a key that locks and unlocks the center floor console only (if equipped).

If you ever lose your keys, your dealer will be able to assist you with obtaining replacements.

NOTICE:

Your vehicle has a number of new features that can help prevent theft. But you can have a lot of trouble getting into your vehicle if you ever lock your key inside. You may even have to damage your vehicle to get in. So be sure you have an extra key.

If you ever do get locked out of your vehicle, call the

GM Roadside Assistance Center. See “Roadside

Assistance” in the Index. If your vehicle is equipped with the OnStar system with an active subscription and you lock your keys inside the vehicle, OnStar may be able to send a command to unlock your vehicle. See

“OnStar” in the Index for more information.

2-5

Door Locks

CAUTION:

Unlocked doors can be dangerous.

D Passengers - especially children - can easily open the doors and fall out of a moving vehicle. When a door is locked, the handle won’t open it. You increase the chance of being thrown out of the vehicle in a crash if the doors aren’t locked. So, wear safety belts properly and lock the doors whenever you drive.

D Young children who get into unlocked vehicles may be unable to get out. A child can be overcome by extreme heat and can suffer permanent injuries or even death from heat stroke. Always lock your vehicle whenever you leave it.

D Outsiders can easily enter through an unlocked door when you slow down or stop your vehicle. Locking your doors can help prevent this from happening.

2-6

There are several ways to lock and unlock your vehicle.

You can use the keyless entry system (if equipped).

You can also use your key.

To lock the door from the inside, slide the lever rearward. To unlock the door, slide the lever forward.

Power Door Locks

Press the raised side of the switch, marked L on either front door to lock all the doors at once.

If your vehicle has this power door lock switch, press the bottom of the switch on either front door to lock all the doors at once.

Press the recessed side of the switch marked U to unlock all the doors at once.

Press the top of the switch to unlock all the doors at once.

2-7

On the passenger side of the rear cargo door or liftgate opening trim there is a power lock switch which can be used to lock or unlock all of the doors.

Programmable Automatic Door Locks

(If Equipped)

If your vehicle has power door locks, it is equipped with a feature that enables you to program your power door locks.

Your vehicle left the factory programmed to automatically lock all doors when the vehicle is shifted out of PARK (P), and all doors unlock when the vehicle is shifted into PARK (P). You can set the automatic door lock feature to unlock the doors you select once the vehicle is in PARK (P).

The following instructions detail how to program your door locks.

If the rear lock switch is pressed with the rear doors open, all of the doors will lock five seconds after the cargo doors are closed.

The power door locks will operate at any time even when the ignition is off.

Operating the power locks may interact with the theft deterrent system (if equipped). See “Content

Theft Deterrent” in the Index.

2-8

To enter the program mode you need to do the following:

1. Beginning with the ignition in OFF. Pull back on the turn signal/multifunction lever all the way toward you until flash to pass is activated, and hold it while you perform the next step.

2. Turn your key to RUN and OFF twice. Then, with the key in OFF, release the turn signal/multifunction lever. Once you do this, you will hear the lock mechanism lock and unlock.

3. You are now ready to program the automatic door locks. Select one of the following four programming options and follow the instructions. You will have thirty seconds to begin programming. If you exceed the thirty second limit, the locks will automatically lock and unlock to indicate you have left the program mode. If this occurs, repeat the procedure beginning with Step 1.

You can exit the program mode any time by turning the ignition to RUN (the locks will automatically lock and unlock to indicate you are leaving the program mode).

If the lock/unlock switches are not pressed while in the programming mode, the auto lock/unlock setting will not be modified.

The following is a list of the available programming options:

D All doors lock/Only the driver’s door unlocks:

Press the lock side of the power lock switch on the door panel once and then the unlock side once.

D All doors lock/All doors unlock: Press the lock side of the power lock switch on the door panel once, and then the unlock side twice.

D All doors lock/None of the doors unlock: Press the lock side of the power lock switch on the door panel once, and then the unlock side three times.

D No doors lock/None of the doors unlock: Press the lock side of the power lock switch on the door panel twice. This turns off the automatic lock feature.

For more information, see your dealer.

2-9

Lockout Prevention

This feature protects you from locking your key in the vehicle when the key is in the ignition and a door is open.

If the power lock switch is pressed when a door is open and the key is in the ignition, all of the doors will lock and then the driver’s door will unlock.

Child Security Locks (If Equipped)

With this feature, you can lock the rear side doors so they cannot be opened from the inside by passengers.

Your vehicle may have one of the two child security lock labels shown.

This feature is located on the inside edge of the rear doors.

Move the lever forward to engage the security feature.

Move the lever rearward to return the door locks to normal operation.

2-10

Keyless Entry System (If Equipped)

If your vehicle has this feature, you can lock and unlock your doors from about 3 feet (1 m) up to 30 feet (9 m) away using the remote keyless entry transmitter supplied with your vehicle.

Your keyless entry system operates on a radio frequency subject to Federal Communications Commission (FCC)

Rules and with Industry Canada.

This device complies with Part 15 of the FCC

Rules. Operation is subject to the following two conditions: (1) this device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation.

This device complies with RSS 210 of Industry

Canada. Operation is subject to the following two conditions: (1) this device may not cause interference, and (2) this device must accept any interference received, including interference that may cause undesired operation of the device.

Changes or modifications to this system by other than an authorized service facility could void authorization to use this equipment.

At times you may notice a decrease in range. This is normal for any remote keyless entry system. If the transmitter does not work or if you have to stand closer to your vehicle for the transmitter to work, try this:

D Check the distance. You may be too far from your vehicle. You may need to stand closer during rainy or snowy weather.

D Check the location. Other vehicles or objects may be blocking the signal. Take a few steps to the left or right, hold the transmitter higher, and try again.

D Check to determine if battery replacement is necessary. See the instructions that follow.

D If you’re still having trouble, see your dealer or a qualified technician for service.

2-11

Operation

UNLOCK: Pressing this button once will unlock the driver’s door. The parking lamps will flash and the interior lights will come on. The ground illumination lamps will come on. Pressing UNLOCK again within three seconds will cause the remaining doors to unlock.

The parking lamps will flash and the interior lights will come on.

LOCK: Pressing this button once will lock all of the doors. Wait one second, then press LOCK again and the horn will chirp.

Operating the keyless entry transmitter may interact with the theft deterrent system. See “Content Theft

Deterrent” in the Index.

Remote Panic Alarm

When the panic button with the horn symbol on the keyless entry transmitter is pressed, the horn will sound and the headlamps and taillamps will flash for up to 30 seconds. This can be turned off by pressing the panic button again, waiting for 30 seconds, or starting the vehicle.

Matching Transmitter(s) to Your Vehicle

Each remote keyless entry transmitter is coded to prevent another transmitter from unlocking your vehicle.

If a transmitter is lost or stolen, a replacement can be purchased through your dealer. Remember to bring any remaining transmitters with you when you go to your dealer. When the dealer matches the replacement transmitter to your vehicle, any remaining transmitters must also be matched. Once your dealer has coded the new transmitter, the lost transmitter will not unlock your vehicle. Each vehicle can have a maximum of four transmitters matched to it.

Battery Replacement

Under normal use, the battery in your remote keyless entry transmitter should last about two years.

You can tell the battery is weak if the transmitter won’t work at the normal range in any location. If you have to get close to your vehicle before the transmitter works, it’s probably time to change the battery.

2-12

NOTICE:

When replacing the battery, use care not to touch any of the circuitry. Static from your body transferred to these surfaces may damage the transmitter.

To replace the battery in the keyless entry transmitter do the following:

2. Remove and replace the battery with a three volt

CR2032 or equivalent battery, positive (+) side up.

3. Align the covers and snap them together.

4. Resynchronize the transmitter.

5. Check the operation of the transmitter.

Resynchronization

Resynchronization may be necessary due to the security method used by this system. The transmitter does not send the same signal twice to the receiver. The receiver will not respond to a signal that has been sent previously. This prevents anyone from recording and playing back the signal from the transmitter.

To resynchronize your transmitter, stand close to your vehicle and press and hold the LOCK and UNLOCK buttons on the transmitter at the same time for seven seconds. The door locks should cycle to confirm synchronization. If the locks do not cycle, see your dealer for service.

1. Insert a dime, or similar object, in the slot between the covers of the transmitter housing near the key ring hole. Remove the bottom by twisting the dime.

2-13

Liftgate

CAUTION:

It can be dangerous to drive with the liftgate glass, liftgate or rear doors open because carbon monoxide (CO) gas can come into your vehicle.

You can’t see or smell CO. It can cause unconsciousness and even death.

If you must drive with the liftgate glass, liftgate or rear doors open or if electrical wiring or other cable connections must pass through the seal between the body and the liftgate glass, liftgate or rear doors:

D Make sure all other windows are shut.

D Turn the fan on your heating or cooling system to its highest speed with the setting on VENT or OUTSIDE AIR. That will force outside air into your vehicle. See

“Comfort Controls” in the Index.

D If you have air outlets on or under the instrument panel, open them all the way.

See “Engine Exhaust” in the Index.

2-14

Liftgate Glass and Liftgate

To open a mechanical lock system from the outside, insert the key into the lock and turn it counterclockwise to unlock the glass and liftgate.

The liftgate glass can be opened using the button on the liftgate after the doors have been unlocked. This can be done by using either the power door locks or the remote keyless entry system.

To open the entire liftgate, lift the handle located in the center of the door.

To lock a power lock system from the outside, insert the key into the lock button and turn clockwise. All doors will lock. You may also use the keyless entry system or the power door locks to lock the liftgate and liftgate glass.

Panel Doors

To open the rear panel doors, you must open the passenger’s side panel door first. If the door is locked, insert your door key in the lock and turn it counterclockwise to unlock it.

To open the passenger’s side panel door, pull on the handle and pull the door open.

To open the driver’s side panel door, first open the passenger’s side door. Then, pull the handle on the left door edge out and pull the door open.

To close the doors, close the driver’s side door first.

After securely closing the door, close the passenger’s side door. Make sure both doors are latched securely.

To lock the rear doors from outside the vehicle, put your key in the lock and turn it clockwise. If you have power door locks, you can lock the side doors as well as the rear doors from inside the vehicle. For more information, see “Power Door Locks” earlier in this section.

Theft

Vehicle theft is big business, especially in some cities.

Although your vehicle has a number of theft deterrent features, we know that nothing we put on it can make it impossible to steal. However, there are ways you can help.

Key in the Ignition

If you leave your vehicle with the keys inside, it’s an easy target for joy riders or professional thieves - so don’t do it.

When you park your vehicle and open the driver’s door, you’ll hear a chime reminding you to remove your key from the ignition and take it with you. Always do this.

Your ignition and transmission will be locked. Also remember to lock the doors.

If the key is in the ignition, with any door open, and you try to lock your doors with the power door locks, the driver’s door will not stay locked. This will help to keep you from locking your keys in the vehicle.

2-15

Parking at Night

Park in a lighted spot, close all windows and lock your vehicle. Remember to keep your valuables out of sight.

Put them in a storage area, or take them with you.

Parking Lots

Even if you park in a lot where someone will be watching your vehicle, it’s still best to lock it up and take your keys. But what if you have to leave your ignition key? What if you have to leave something valuable in your vehicle?

D Put your valuables in a storage area, like your glove box.

D If your vehicle has a remote keyless entry system, take the transmitter with you.

D Lock all the doors except the driver’s.

Content Theft

-

Deterrent

(If Equipped)

Your vehicle may be equipped with a content theft deterrent alarm system.

With this system, the

SECURITY message will flash as you open the door

(if your ignition is off).

This message reminds you to activate the theft deterrent system. Here’s how to do it:

1. Open the door.

2. Lock the door with the power door lock switch or the remote keyless entry transmitter. The SECURITY message should come on and stay on. If using the remote keyless entry transmitter, the door does not need to be open.

3. Close all doors. The SECURITY message should go off after approximately 15 seconds. The alarm is not armed until the SECURITY message goes off.

2-16

If a door is opened without the key or the remote keyless entry transmitter, the alarm will go off. Your vehicle’s headlamps will flash and the horn will sound for about two minutes, then will turn off to save the battery power.

Remember, the theft deterrent system won’t activate if you lock the doors with a key or use the manual door lock. It activates only if you use a power door lock switch with the door open, or with the remote keyless entry transmitter. You should also remember that you can start your vehicle with the correct ignition key if the alarm has been set off.

Here’s how to avoid setting off the alarm by accident:

D If you don’t want to activate the theft deterrent system, the vehicle should be locked with the door key after the doors are closed.

D Always unlock a door with a key, or use the remote keyless entry transmitter. Unlocking a door any other way will set off the alarm if the system has been armed.

If you set off the alarm by accident, unlock any door with the key. You can also turn off the alarm by pressing

UNLOCK on the remote keyless entry transmitter or by placing the key in the ignition and turning it to START.

Testing the Alarm

The alarm can be tested by following these steps:

1. From inside the vehicle, lower the driver’s window and open the driver’s door.

2. Activate the system by locking the doors with the power door lock switch while the door is open, or with the remote keyless entry transmitter.

3. Get out of the vehicle, close the door and wait for the

SECURITY message to go out.

4. Then reach in through the window, unlock the door with the manual door lock and open the door. This should set off the alarm.

If the alarm does not sound when it should but the vehicle’s headlamps flash, check to see if the horn works. The horn fuse may be blown. To replace the fuse, see “Fuses and Circuit Breakers” in the Index.

If the alarm does not sound or the vehicle’s headlamps do not flash, the vehicle should be serviced by an authorized service center.

2-17

Passlock

R

Your vehicle is equipped with the Passlock theft deterrent system.

Passlock is a passive theft deterrent system. Passlock enables fuel if the ignition lock cylinder is turned with a valid key. If a correct key is not used or the ignition lock cylinder is tampered with, fuel is disabled.

If the engine stalls and the SECURITY message flashes, wait until the light stops flashing before trying to restart the engine. Remember to release the key from START as soon as the engine starts.

If the engine is running and the SECURITY message comes on, you will be able to restart the engine if you turn the engine off. However, your Passlock system is not working properly and must be serviced by your dealer. Your vehicle is not protected by Passlock at this time. You may also want to check the fuse (see “Fuses and Circuit Breakers” in the Index). See your dealer for service.

In an emergency, call the GM Roadside Assistance

Center. See “Roadside Assistance” in the Index.

New Vehicle “Break

-

In”

NOTICE:

Your vehicle doesn’t need an elaborate

“break in.” But it will perform better in the long run if you follow these guidelines:

D Keep your speed at 55 mph (88 km/h) or less for the first 500 miles (805 km).

D Don’t drive at any one speed - fast or slow - for the first 500 miles (805 km).

Don’t make full throttle starts.

D Avoid making hard stops for the first

200 miles (322 km) or so. During this time your new brake linings aren’t yet broken in. Hard stops with new linings can mean premature wear and earlier replacement.

Follow this breaking in guideline every time you get new brake linings.

D Don’t tow a trailer during break in.

See “Towing a Trailer” in the Index for more information.

2-18

Ignition Positions

With the key in the ignition switch, you can turn the key to five different positions.

A (ACCESSORY): This position lets you use things like the radio, power windows and the windshield wipers when the engine is off. Push in the key and turn it toward you.

B (LOCK): This position locks your ignition and transmission. It’s a theft deterrent feature. You will only be able to remove your key when the ignition is turned to LOCK.

NOTICE:

If your key seems stuck in LOCK and you can’t turn it, be sure you are using the correct key; if so, is it all the way in? Turn the key only with your hand. Using a tool to force it could break the key or the ignition switch. If none of this works, then your vehicle needs service.

C (OFF): This position lets you turn off the engine.

Use OFF if you must have your vehicle in motion while the engine is off (for example, if your vehicle is being pushed).

D (RUN): This is the position for driving.

E (START): This position starts your engine.

2-19

Retained Accessory Power (RAP)

(If Equipped)

Your vehicle may be equipped with a Retained

Accessory Power (RAP) feature which will allow certain features on your vehicle to continue to work up to 20 minutes after the ignition key is turned to OFF.

Your radio, power windows, sunroof (if equipped), and

OnStar

R

System (if equipped) will work when the ignition key is in RUN or ACCESSORY. Once the key is turned from RUN to OFF, these features will continue to work for up to 20 minutes or until a door is opened.

Starting Your Engine

Move your shift lever to PARK (P) or NEUTRAL (N).

Your engine won’t start in any other position - that’s a safety feature. To restart when you’re already moving, use NEUTRAL (N) only.

NOTICE:

Don’t try to shift to PARK (P) if your vehicle is moving. If you do, you could damage the transmission. Shift to PARK (P) only when your vehicle is stopped.

2-20

1. With your foot off the accelerator pedal, turn the ignition key to START. When the engine starts, let go of the key. The idle speed will go down as your engine gets warm.

NOTICE:

Holding your key in START for longer than

15 seconds at a time will cause your battery to be drained much sooner. And the excessive heat can damage your starter motor. Wait about 15 seconds between each try to help avoid draining your battery or damaging your starter.

2. If it doesn’t start within 10 seconds, push the accelerator pedal all the way to the floor, while you hold the ignition key in START. When the engine starts, let go of the key and let up on the accelerator pedal. Wait about 15 seconds between each try.

When starting your engine in very cold weather (below

0

_F or 18

_C), do this:

1. With your foot off the accelerator pedal, turn the ignition key to START and hold it there up to

15 seconds. When the engine starts, let go of the key.

2. If your engine still won’t start (or starts but then stops), it could be flooded with too much gasoline.

Try pushing your accelerator pedal all the way to the floor and holding it there as you hold the key in

START for about three seconds. When the engine starts, let go of the key and accelerator. If the vehicle starts briefly but then stops again, do the same thing, but this time keep the pedal down for five or six seconds. This clears the extra gasoline from the engine.

Engine Coolant Heater (If Equipped)

In very cold weather,

0

_F ( 18

_C) or colder, the engine coolant heater can help.

You’ll get easier starting and better fuel economy during engine warm up.

Usually, the coolant heater should be plugged in a minimum of four hours prior to starting your vehicle.

At temperatures above 32

_F (0_C), use of the coolant heater is not required.

NOTICE:

Your engine is designed to work with the electronics in your vehicle. If you add electrical parts or accessories, you could change the way the engine operates. Before adding electrical equipment, check with your dealer. If you don’t, your engine might not perform properly.

2-21

To Use the Engine Coolant Heater

1. Turn off the engine.

2. Open the hood and unwrap the electrical cord. The cord is located on the driver’s side of the engine compartment, near the power steering fluid reservoir.

3. Plug it into a normal, grounded 110 volt AC outlet.

How long should you keep the coolant heater plugged in? The answer depends on the outside temperature, the kind of oil you have, and some other things. Instead of trying to list everything here, we ask that you contact your dealer in the area where you’ll be parking your vehicle. The dealer can give you the best advice for that particular area.

Automatic Transmission Operation

CAUTION:

Plugging the cord into an ungrounded outlet could cause an electrical shock. Also, the wrong kind of extension cord could overheat and cause a fire. You could be seriously injured. Plug the cord into a properly grounded three prong

110 volt AC outlet. If the cord won’t reach, use a heavy duty three prong extension cord rated for at least 15 amps.

There are several different positions for your shift lever.

4. Before starting the engine, be sure to unplug and store the cord as it was before to keep it away from moving engine parts. If you don’t, it could be damaged.

2-22

Your vehicle is equipped with an automatic transmission and features an electronic shift position indicator within the instrument panel cluster. This display must be powered anytime the shift lever is capable of being moved out of PARK (P). This means that if your key is in OFF, rather than LOCK, there will be a small current drain on your battery which could discharge your battery over a period of time. If you have to leave your key in the ignition in OFF for an extended period, it is recommended that you remove the IGN 0 fuse from the instrument panel fuse block. See “Fuses and Circuit

Breakers” in the Index.

PARK (P): This position locks your rear wheels. It’s the best position to use when you start your engine because your vehicle can’t move easily.

CAUTION:

It is dangerous to get out of your vehicle if the shift lever is not fully in PARK (P) with the parking brake firmly set. Your vehicle can roll.

Don’t leave your vehicle when the engine is running unless you have to. If you have left the engine running, the vehicle can move suddenly.

You or others could be injured. To be sure your vehicle won’t move, even when you’re on fairly level ground, always set your parking brake and move the shift lever to PARK (P).

If you have four wheel drive, your vehicle will be free to roll - even if your shift lever is in

PARK (P) - if your transfer case is in NEUTRAL.

So, be sure the transfer case is in a drive gear, two wheel high (2H) or four wheel high (4H) or four wheel low (4L) - not in NEUTRAL. See

“Shifting Into PARK (P)” in the Index.

See “Shifting Into PARK (P)” in the Index.

If you’re pulling a trailer, see “Towing a Trailer” in the Index.

2-23

REVERSE (R): Use this gear to back up.

NOTICE:

Shifting to REVERSE (R) while your vehicle is moving forward could damage your transmission. Shift to REVERSE (R) only after your vehicle is stopped.

To rock your vehicle back and forth to get out of snow, ice or sand without damaging your transmission, see

“Stuck: In Sand, Mud, Ice or Snow” in the Index.

NEUTRAL (N): In this position, your engine doesn’t connect with the wheels. To restart when you’re already moving, use NEUTRAL (N) only. Also, use

NEUTRAL (N) when your two wheel drive vehicle is being towed.

CAUTION:

Shifting out of PARK (P) or NEUTRAL (N) while your engine is “racing” (running at high speed) is dangerous. Unless your foot is firmly on the brake pedal, your vehicle could move very rapidly. You could lose control and hit people or objects. Don’t shift out of PARK (P) or

NEUTRAL (N) while your engine is racing.

NOTICE:

Damage to your transmission caused by shifting out of PARK (P) or NEUTRAL (N) with the engine racing isn’t covered by your warranty.

2-24

DRIVE (D): This position is for normal driving. If you need more power for passing, and you’re:

D Going less than about 35 mph (56 km/h), push your accelerator pedal about halfway down.

D Going about 35 mph (56 km/h) or more, push the accelerator all the way down.

You’ll shift down to the next gear and have more power.

DRIVE (D) can be used when towing a trailer, carrying a heavy load, driving on steep hills or for off road driving. You may want to shift the transmission to

THIRD (3) or, if necessary, a lower gear selection if the transmission shifts too often.

THIRD (3): This position is also used for normal driving, however it offers more power and lower fuel economy than DRIVE (D).

SECOND (2): This position gives you more power but lower fuel economy. You can use SECOND (2) on hills.

It can help control your speed as you go down steep mountain roads, but then you would also want to use your brakes off and on.

If you manually select SECOND (2) in a light duty automatic transmission, the transmission will drive in second gear. You may use this feature for reducing the speed of the rear wheels when you are trying to start your vehicle from a stop on slippery road surfaces.

FIRST (1): This position gives you even more power

(but lower fuel economy) than SECOND (2). You can use it on very steep hills, or in deep snow or mud. If the shift lever is put in FIRST (1) while the vehicle is moving forward, the transmission won’t shift into first gear until the vehicle is going slowly enough.

NOTICE:

If your rear wheels can’t rotate, don’t try to drive. This might happen if you were stuck in very deep sand or mud or were up against a solid object. You could damage your transmission.

Also, if you stop when going uphill, don’t hold your vehicle there with only the accelerator pedal. This could overheat and damage the transmission. Use your brakes or shift into

PARK (P) to hold your vehicle in position on a hill.

On cold days, approximately 32

_F (0_C) or colder, your transmission is designed to shift differently until the engine reaches normal operating temperature. This is intended to improve heater performance.

2-25

Tow/Haul Mode Selector Button

Parking Brake

To set the parking brake, hold the regular brake pedal down with your right foot. Push down the parking brake pedal with your left foot.

If the ignition is on, the brake system warning light will flash. A chime will activate when the parking brake is applied and the vehicle is moving at least 3 mph

(5 km/h) for at least three seconds.

Your vehicle is equipped with a tow/haul mode. The selector button is located on the end of the column shift lever. You can use this feature to assist when towing or hauling a heavy load. See “Tow/Haul Mode” in the

Index for more information.

The tow/haul mode also interacts with the Autoride t feature, if your vehicle is so equipped, to enhance the ride when trailering or with a loaded vehicle. See

“Autoride t” in the Index.

2-26

To release the parking brake, hold the regular brake pedal down. Pull the bottom edge of the lever, located above the parking brake pedal, marked BRAKE

RELEASE, to release the parking brake.

If the ignition is on when the parking brake is released, the brake system warning light will go off.

NOTICE:

Driving with the parking brake on can cause your rear brakes to overheat. You may have to replace them, and you could also damage other parts of your vehicle.

If you are towing a trailer and are parking on any hill, see “Towing a Trailer” in the Index.

Shifting Into PARK (P)

CAUTION:

It can be dangerous to get out of your vehicle if the shift lever is not fully in PARK (P) with the parking brake firmly set. Your vehicle can roll. If you have left the engine running, the vehicle can move suddenly. You or others could be injured.

To be sure your vehicle won’t move, even when you’re on fairly level ground, use the steps that follow. With four wheel drive if your transfer case is in NEUTRAL, your vehicle will be free to roll, even if your shift lever is in PARK (P). So, be sure the transfer case is in a drive gear - not in

NEUTRAL. If you’re pulling a trailer, see

“Towing a Trailer” in the Index.

1. Hold the brake pedal down with your right foot and set the parking brake.

2-27

2. Move the shift lever into PARK (P) position like this:

D Pull the shift lever toward you.

D Move the lever up as far as it will go.

3. Be sure the transfer case is in a drive gear - not in NEUTRAL (N).

4. Turn the ignition key to LOCK.

5. Remove the key and take it with you. If you can leave your vehicle with the ignition key in your hand, your vehicle is in PARK (P).

2-28

Leaving Your Vehicle With the

Engine Running

CAUTION:

It can be dangerous to leave your vehicle with the engine running. Your vehicle could move suddenly if the shift lever is not fully in PARK (P) with the parking brake firmly set. If you have four wheel drive and your transfer case is in

NEUTRAL, your vehicle will be free to roll, even if your shift lever is in PARK (P). So be sure the transfer case is in a drive gear - not in

NEUTRAL. And, if you leave the vehicle with the engine running, it could overheat and even catch fire. You or others could be injured. Don’t leave your vehicle with the engine running unless you have to.

If you have to leave your vehicle with the engine running, be sure your vehicle is in PARK (P) and the parking brake is firmly set before you leave it. After you move the shift lever into PARK (P), hold the regular brake pedal down. Then, see if you can move the shift lever away from PARK (P) without first pulling it toward you. If you can, it means that the shift lever wasn’t fully locked into PARK (P).

Torque Lock

If you are parking on a hill and you don’t shift your transmission into PARK (P) properly, the weight of the vehicle may put too much force on the parking pawl in the transmission. You may find it difficult to pull the shift lever out of PARK (P). This is called “torque lock.”

To prevent torque lock, set the parking brake and then shift into PARK (P) properly before you leave the driver’s seat. To find out how, see “Shifting Into

PARK (P)” in the Index.

When you are ready to drive, move the shift lever out of

PARK (P) before you release the parking brake.

If torque lock does occur, you may need to have another vehicle push yours a little uphill to take some of the pressure from the parking pawl in the transmission, so you can pull the shift lever out of PARK (P).

2-29

Shifting Out of PARK (P)

Your vehicle has an automatic transmission shift lock control system. You have to fully apply your regular brakes before you can shift from PARK (P) when the ignition is in RUN. See “Automatic Transmission” in the Index.

If you cannot shift out of PARK (P), ease pressure on the shift lever and push the shift lever all the way up into PARK (P) as you maintain brake application. Then, move the shift lever into the gear you want.

If you ever hold the brake pedal down but still can’t shift out of PARK (P), try this:

1. Turn the key to OFF.

2. Apply and hold the brake until the end of Step 4.

3. Shift the vehicle to NEUTRAL (N).

4. Start the vehicle and then shift to the drive gear you want.

5. Have the system fixed as soon as you can.

Parking Over Things That Burn

CAUTION:

Things that can burn could touch hot exhaust parts under your vehicle and ignite. Don’t park over papers, leaves, dry grass or other things that can burn.

2-30

Engine Exhaust

CAUTION:

Engine exhaust can kill. It contains the gas carbon monoxide (CO), which you can’t see or smell. It can cause unconsciousness and death.

You might have exhaust coming in if:

D Your exhaust system sounds strange or different.

D Your vehicle gets rusty underneath.

D Your vehicle was damaged in a collision.

D Your vehicle was damaged when driving over high points on the road or over road debris.

D Repairs weren’t done correctly.

D Your vehicle or exhaust system had been modified improperly.

If you ever suspect exhaust is coming into your vehicle:

D Drive it only with all the windows down to blow out any CO; and

D Have your vehicle fixed immediately.

Running Your Engine While

You’re Parked

It’s better not to park with the engine running. But if you ever have to, here are some things to know.

CAUTION:

Idling the engine with the climate control system off could allow dangerous exhaust into your vehicle. See the earlier Caution under

“Engine Exhaust.”

Also, idling in a closed in place can let deadly carbon monoxide (CO) into your vehicle even if the fan is at the highest setting. One place this can happen is a garage. Exhaust - with

CO - can come in easily. NEVER park in a garage with the engine running.

Another closed in place can be a blizzard.

See “Blizzard” in the Index.

2-31

CAUTION:

It can be dangerous to get out of your vehicle if the shift lever is not fully in PARK (P) with the parking brake firmly set. Your vehicle can roll.

Don’t leave your vehicle when the engine is running unless you have to. If you’ve left the engine running, the vehicle can move suddenly.

You or others could be injured. To be sure your vehicle won’t move, even when you’re on fairly level ground, always set your parking brake and move the shift lever to PARK (P).

Four wheel drive vehicles with the transfer case in NEUTRAL will allow the vehicle to roll, even if your shift lever is in PARK (P). So, be sure the transfer case is in a drive gear - not in

NEUTRAL. Always set your parking brake.

Follow the proper steps to be sure your vehicle won’t move. See “Shifting Into PARK (P)” in the Index.

If you’re pulling a trailer, see “Towing a Trailer” in the Index.

2-32

Level Control (If Equipped)

Self

-

Adjusting

The self adjusting rear suspension is available on

C/K 1500 vehicles and is available with the premium smooth ride suspension package.

This type of level control will provide a leveled riding position as well as improved handling under a variety of passenger and loading conditions. A hydraulic pump inside each rear shock absorber raises the rear of the vehicle to the proper height, based on inputs from the road surface, while the vehicle is being driven. It takes approximately 2 miles (3.2 km) of driving for the leveling to complete, depending on the road surface conditions.

If the loaded vehicle is not moved for approximately twelve hours, the leveling system may bleed down to a lower height. This can be especially apparent if a trailer is left attached to a parked vehicle for long periods of time. The vehicle must be driven to re level the vehicle.

If a self equalizing hitch is being used, the vehicle should be driven approximately 2 miles (3.2 km) with the trailer prior to adjusting (leveling) the hitch.

Automatic Level Control

The automatic level control rear suspension is available on C/K 1500 vehicles and comes as a part of the

Autoride t suspension.

This type of level control is fully automatic and will provide a better leveled riding position as well as better handling under a variety of passenger and loading conditions. An air compressor connected to the rear shocks will raise or lower the rear of the vehicle to maintain proper vehicle height. The system is activated when the ignition key is turned to RUN and will automatically adjust vehicle height thereafter. The system may exhaust (lower vehicle height) for up to ten minutes after the ignition key has been turned to OFF.

You may hear the air compressor operating when the height is being adjusted.

If a self equalizing hitch is being used, it is recommended to allow the shocks to inflate, thereby leveling the vehicle prior to adjusting the hitch.

Autoride

t (If Equipped)

The Autoride feature will provide a superior vehicle ride and handling under a variety of passenger and loading conditions.

The system is fully automatic and uses a computer controller to continuously monitor vehicle speed, wheel to body position, lift/drive and steering position of the vehicle. The controller then sends signals to each shock absorber to independently adjust the damping level to provide the optimum vehicle ride.

Autoride also interacts with the tow/haul switch that, when engaged, will provide additional control of the shock absorbers. This additional control results in better ride and handling characteristics when the vehicle is loaded or towing a trailer. See “Tow/Haul Mode” in the

Index for more information.

Locking Rear Axle (If Equipped)

If your vehicle has this feature, your locking rear axle can give you additional traction on snow, mud, ice, sand or gravel. It works like a standard axle most of the time, but when one of the rear wheels has no traction and the other does, this feature will allow the wheel with traction to move the vehicle.

2-33

Four

-

Wheel Drive (If Equipped)

If your vehicle has four wheel drive, you can send your engine’s driving power to all four wheels for extra traction. To get the most satisfaction out of four wheel drive, you must be familiar with its operation. Read the part that follows before using four wheel drive. See the appropriate text for the transfer case in your vehicle.

NOTICE:

Driving in the 4 WHEEL HIGH (4H) or

4 WHEEL LOW (4L) positions for a long time on dry or wet pavement could shorten the life of your vehicle’s drivetrain.

Front Axle Locking Feature

The front axle locks and unlocks automatically when you shift the transfer case. Some delay for the axle to lock or unlock is normal.

CAUTION:

Shifting the transfer case to NEUTRAL can cause your vehicle to roll even if the transmission is in PARK (P). You or someone else could be seriously injured. Be sure to set the parking brake before placing the transfer case in

NEUTRAL. See “Parking Brake” in the Index.

Automatic Transfer Case (If Equipped)

The transfer case buttons are located to the left of the instrument panel cluster.

Use these switches to shift into and out of four wheel drive.

2-34

You can choose among four driving settings:

2HI: This setting is used for driving in most street and highway situations. Your front axle is not engaged in two wheel drive. This setting also provides the best fuel economy.

AUTO 4WD: This setting is ideal for use when road conditions are variable. When driving your vehicle in

AUTO 4WD, the front axle is engaged, but the vehicle’s power is sent only to the rear wheels. When the vehicle senses a loss of traction, the system will automatically engage four wheel drive. Driving in this mode results in slightly lower fuel economy than 2HI.

4HI: Use 4HI when you need extra traction, such as on snowy or icy roads or in most off road situations.

This setting also engages your front axle to help drive your vehicle. This is the best setting to use when plowing snow.

4LO: This setting also engages your front axle and delivers extra torque. You may never need 4LO. It sends maximum power to all four wheels. You might choose

4LO if you are driving off road in deep sand, deep mud, deep snow and climbing or descending steep hills.

2-35

CAUTION:

Shifting the transfer case to NEUTRAL can cause your vehicle to roll even if the transmission is in PARK (P). You or someone else could be seriously injured. Be sure to set the parking brake before placing the transfer case in

NEUTRAL. See “Parking Brake” in the Index.

NEUTRAL: Shift the vehicle’s transfer case to

NEUTRAL only when towing your vehicle. See

“Recreational Vehicle Towing” or “Towing Your

Vehicle” in the Index for more information.

Indicator lights in the switches show which setting you are in. The indicator lights will come on briefly when you turn on the ignition and one will stay on. If the lights do not come on, you should take your vehicle to your dealer for service. An indicator light will flash while shifting the transfer case. It will remain illuminated when the shift is complete. If for some reason the transfer case cannot make a requested shift, it will return to the last chosen setting.

If the SERVICE 4WD light stays on, you should take your vehicle to your dealer for service. See “Service

4WD” in the Index for further information.

2-36

Shifting into 4HI or AUTO 4WD

Press and release the 4HI or AUTO 4WD switch. This can be done at any speed (except when shifting from

4LO), and the indicator light will flash while shifting.

It will remain illuminated when the shift is completed.

Shifting into 2HI

Press and release the 2HI switch. This can be done at any speed (except when shifting from 4LO).

Shifting into 4LO

To shift to 4LO, the ignition must be in RUN and the vehicle must be stopped or moving less than 3 mph

(4.8 km/h) with the transmission in NEUTRAL (N). The preferred method for shifting into 4LO is to have your vehicle moving 1 to 2 mph (1.6 to 3.2 km/h). Press and release the 4LO switch. You must wait for the 4LO indicator light to stop flashing and remain illuminated before shifting your transmission in gear.

If the 4LO switch is pressed when your vehicle is in gear and/or moving, the 4LO indicator light will flash for 30 seconds and not complete the shift unless your vehicle is moving less than 3 mph (4.8 km/h) and the transmission is in NEUTRAL (N). After 30 seconds the transfer case will return to the setting last chosen.

Shifting Out of 4LO

To shift from 4LO to 4HI, AUTO 4WD or 2HI your vehicle must be stopped or moving less than 3 mph

(4.8 km/h) with the transmission in NEUTRAL (N) and the ignition in RUN. The preferred method for shifting out of 4LO is to have your vehicle moving 1 to 2 mph

(1.6 to 3.2 km/h). Press and release the 4HI, AUTO

4WD or 2HI switch. You must wait for the 4HI, AUTO

4WD or 2HI indicator light to stop flashing and remain illuminated before shifting your transmission into gear.

If the 4HI, AUTO 4WD or 2HI switch is pressed when your vehicle is in gear and/or moving, the 4HI, AUTO

4WD or 2HI indicator light will flash for 30 seconds but will not complete the shift unless your vehicle is moving less than 3 mph (4.8 km/h) and the transmission is in NEUTRAL (N).

Shifting into NEUTRAL

To shift the transfer case to NEUTRAL do the following:

1. Make sure the vehicle is parked so that it will not roll:

2. Set the parking brake.

3. Start the vehicle or turn the ignition to RUN.

4. Connect the vehicle to the towing vehicle.

5. Put the transmission in NEUTRAL (N).

6. Shift the transfer case to 2HI.

7. Simultaneously press and hold the 2HI and 4LO buttons for 10 seconds. The red NEUTRAL light will come on when the transfer case shift to

NEUTRAL is complete.

8. Shift the transmission to REVERSE (R) for one second, then shift the transmission to

DRIVE (D) for one second.

9. Turn the ignition to OFF.

10. Place the transmission shift lever in PARK (P).

11. Release the parking brake prior to towing.

2-37

Shifting Out of NEUTRAL

To shift out of NEUTRAL:

1. Set the parking brake and apply the regular brake pedal.

2. Shift the transmission to NEUTRAL (N) and turn the ignition to RUN with the engine off.

3. Press the button for the desired transfer case shift position (2HI, 4HI, AUTO 4WD or 4LO).

4. After the transfer case has shifted out of NEUTRAL the red light will go out.

5. You may start the engine and shift the transmission to the desired position.

Horn

To sound the horn, press the center pad on the steering wheel.

Tilt Wheel

A tilt wheel allows you to adjust the steering wheel before you drive. You can raise it to the highest level to give your legs more room when you exit and enter your vehicle.

The tilt steering wheel lever is located on the lower left side of the column.

To tilt the wheel, hold the steering wheel and pull the lever. Then move the steering wheel to a comfortable position and release the lever to lock the wheel in place.

2-38

Turn Signal/Multifunction Lever

Turn and Lane Change Signals

The turn signal has two upward (for right) and two downward (for left) positions. These positions allow you to signal a turn or a lane change.

To signal a turn, move the lever all the way up or down.

When the turn is finished, the lever will return automatically.

An arrow on the instrument panel cluster will flash in the direction of the turn or lane change.

The lever on the left side of the steering column includes the following:

D Turn and Lane Change Signals

D Headlamp High/Low Beam Changer

D Flash to Pass Feature

D Windshield Wipers

D Windshield Washer

D Cruise Control (If Equipped)

For information on the exterior lamps, see “Exterior

Lamps” earlier in this section.

To signal a lane change, just raise or lower the lever until the arrow starts to flash. Hold it there until you complete your lane change. The lever will return by itself when you release it.

If you move the lever all the way up or down, and the arrow flashes at twice the normal rate, a signal bulb may be burned out and other drivers may not see your turn signal.

If a bulb is burned out, replace it to help avoid an accident. If the arrows don’t go on at all when you signal a turn, check for burned out bulbs and a blown fuse. See “Fuses and Circuit Breakers” in the Index.

2-39

Turn Signal On Chime

If your turn signal is left on for more than 3/4 of a mile (1.2 km), a chime will sound at each flash of the turn signal. To turn off the chime, move the turn signal lever to the off position.

Headlamp High/Low Beam Changer

To change the headlamps from low to high beam or high to low beam, pull the multifunction lever all the way toward you. Then release it.

When the high beams are on, this light on the instrument panel cluster also will be on.

If your headlamps are off or on low beam, your high beam headlamps will turn on. They’ll stay on as long as you hold the lever toward you and the high beam indicator on the instrument panel cluster will come on. Release the lever to turn the high beam headlamps off.

Windshield Wipers

Flash-To-Pass Feature

This feature allows you to use your high beam headlamps to signal a driver in front of you that you want to pass. It works even if your headlamps are off.

To use it, pull the turn signal lever toward you, but not so far that you hear it click.

2-40

You control the windshield wipers by turning the band with the wiper symbol on it.

For a single wiping cycle, turn the band to MIST. Hold it there until the wipers start, then let go. The wipers will stop after one wipe. If you want more wipes, hold the band on MIST longer.

You can set the wiper speed for a long or short delay between wipes. This can be very useful in light rain or snow. Turn the band to choose the delay time. The closer to LO, the shorter the delay.

For steady wiping at low speed, turn the band away from you to the LO position. For high speed wiping, turn the band further, to HI. To stop the wipers, move the band to the OFF position.

Be sure to clear ice and snow from the wiper blades before using them. If they’re frozen to the windshield, carefully loosen or thaw them. If your blades do become worn or damaged, get new blades or blade inserts.

Windshield Washer

There is a paddle marked with the windshield washer symbol at the top of the multifunction lever. To spray washer fluid on the windshield, push the paddle. The wipers will clear the window and then either stop or return to your preset speed.

CAUTION:

In freezing weather, don’t use your washer until the windshield is warmed. Otherwise the washer fluid can form ice on the windshield, blocking your vision.

Rear Window Washer/Wiper

This control is located on the instrument panel.

To turn the rear wiper on, turn the control to either 1 or 2. For long delayed wiping, turn the control to 1. For short delayed wiping, turn the control to 2. To turn the wiper off, turn the control to 0.

2-41

To wash the window, press the knob.

The rear window washer uses the same fluid bottle as the windshield washer. However, the rear window washer will run out of fluid before the windshield washer. If you can wash your windshield but not your rear windows, check the fluid level.

Cruise Control (If Equipped)

With cruise control, you can maintain a speed of about

25 mph (40 km/h) or more without keeping your foot on the accelerator. This can really help on long trips.

Cruise control does not work at speeds below about

25 mph (40 km/h).

If you apply your brakes, the cruise control will disengage.

CAUTION:

D Cruise control can be dangerous where you can’t drive safely at a steady speed. So, don’t use your cruise control on winding roads or in heavy traffic.

D Cruise control can be dangerous on slippery roads. On such roads, fast changes in tire traction can cause needless wheel spinning, and you could lose control. Don’t use cruise control on slippery roads.

2-42

Setting Cruise Control

CAUTION:

If you leave your cruise control switch on when you’re not using cruise, you might hit a button and go into cruise when you don’t want to. You could be startled and even lose control. Keep the cruise control switch off until you want to use cruise control.

1. Move the cruise control switch to ON.

2. Get up to the speed you want.

3. Press in the SET button at the end of the lever and release it.

4. Take your foot off the accelerator pedal.

United States Canada

The CRUISE light on the instrument panel will illuminate when the cruise control is engaged.

Resuming a Set Speed

Suppose you set your cruise control at a desired speed and then you apply the brake. This, of course, disengages the cruise control. But you don’t need to reset it.

Once you’re going about 25 mph (40 km/h) or more, you can move the cruise control switch from ON to

R/A (Resume/Accelerate) briefly.

You’ll go right back up to your chosen speed and stay there.

If you continue to hold the switch at R/A, the vehicle will keep going faster until you release the switch or apply the brake. So unless you want to go faster, don’t hold the switch at R/A.

2-43

Increasing Speed While Using Cruise Control

There are two ways to go to a higher speed:

D Use the accelerator pedal to get to the higher speed.

Press the SET button at the end of the lever, then release the button and the accelerator pedal. You’ll now cruise at the higher speed.

D Move the cruise switch from ON to R/A. Hold it there until you get up to the speed you want, and then release the switch. To increase your speed in very small amounts, move the switch to R/A briefly.

Each time you do this, your vehicle will go about

1 mph (1.6 km/h) faster.

Reducing Speed While Using Cruise Control

D Press and hold the SET button at the end of the lever until you reach the lower speed you want, then release it.

D To slow down in very small amounts, press the SET button briefly. Each time you do this, you’ll go about

1 mph (1.6 km/h) slower.

Passing Another Vehicle While Using Cruise Control

Use the accelerator pedal to increase your speed.

When you take your foot off the pedal, your vehicle will slow down to the cruise control speed you set earlier.

Using Cruise Control on Hills

How well your cruise control will work on hills depends upon your speed, load and the steepness of the hills.

When going up steep hills, you may want to step on the accelerator pedal to maintain your speed. When going downhill, you may have to brake or shift to a lower gear to keep your speed down. Of course, applying the brake takes you out of cruise control. Many drivers find this to be too much trouble and don’t use cruise control on steep hills.

Ending Cruise Control

There are two ways to turn off either the cruise control:

D Step lightly on the brake pedal.

D Move the cruise control switch to OFF.

Erasing Speed Memory

When you turn off the cruise control or the ignition, your cruise control set speed memory is erased.

Exterior Lamps

The control on the driver’s side of your instrument panel operates the exterior lamps.

Turn the control clockwise to operate the lamps.

The exterior lamp control has three positions:

(Off): Turning the control to this position turns off all lamps, except the Daytime Running Lamps (DRL). It also puts the system into automatic headlamp mode.

(Parking Lamps): Turning the control to this position turns on the parking lamps, together with the following:

D Sidemarker Lamps

D Taillamps

D License Plate Lamps

D Instrument Panel Lights

D Roof Marker Lamps (If Equipped)

(Headlamps): Turning the control to this position turns on the headlamps, together with the previously listed lamps and lights.

You can switch your headlamps from high to low by pulling on the turn signal/high beam lever.

A circuit breaker protects your headlamps. If you have an electrical overload, your headlamps will flicker on and off. Have your headlamp wiring checked right away if this happens.

2-45

Automatic Headlamp System

When it is dark enough outside, your automatic headlamp system will turn on your headlamps at the normal brightness along with other lamps such as the taillamps, sidemarker, parking lamps and the instrument panel lights. The radio lights will also be dim.

Your vehicle is equipped with a light sensor located on the top of the instrument panel in the defroster grille.

Be sure it is not covered, or the system will be on whenever the ignition is on.

The system may also turn on your headlamps when driving through a parking garage, heavy overcast weather or a tunnel. This is normal.

There is a delay in the transition between the daytime and nighttime operation of the Daytime Running Lamps

(DRL) and the automatic headlamp systems so that driving under bridges or bright overhead street lights does not affect the system. The DRL and automatic headlamp system will only be affected when the light sensor sees a change in lighting lasting longer than the delay.

To idle your vehicle with the automatic headlamp system off, set the parking brake while the ignition is off. Then start your vehicle. The automatic headlamp system will stay off until you release the parking brake.

As with any vehicle, you should turn on the regular headlamp system when you need them.

You may be able to turn off your Automatic Headlamp

System. See “Daytime Running Lamps (DRL)” later in this section for more information.

Lamps On Reminder

A reminder chime will sound when your headlamps or parking lamps are manually turned on and your ignition is in OFF, LOCK or ACCESSORY. To disable the chime, turn the thumbwheel all the way down. In the automatic mode, the headlamps turn off once the ignition key is in OFF.

2-46

Daytime Running Lamps

Daytime Running Lamps (DRL) can make it easier for others to see the front of your vehicle during the day.

DRL can be helpful in many different driving conditions, but they can be especially helpful in the short periods after dawn and before sunset. Fully functional daytime running lamps are required on all vehicles first sold in Canada.

The DRL system will come on when the following conditions are met::

D the ignition is on,

D the exterior lamps control is in automatic headlamp mode,

D the automatic transmission is not in PARK (P),

D the light sensor determines it is daytime and

D the parking brake is released.

When the DRL are on, only your DRL lamps will be on.

The taillamps, sidemarker and other lamps won’t be on.

The instrument panel won’t be lit up either.

When it begins to get dark, the automatic headlamp system will switch from DRL to the headlamps or the last chosen headlamp setting that was used.

When you turn the headlamp switch off, the headlamps will go off, and your DRL lamps will illuminate, provided it is not dark outside.

To idle an automatic transmission equipped vehicle with the DRL off, set the parking brake. Shifting the transmission into PARK (P) will also allow you to idle the vehicle with the DRL off. The DRL will stay off until you release the parking brake or shift the transmission out of PARK (P).

This procedure applies only to vehicles first sold in the

United States.

When necessary, you may turn off the Automatic

Headlamp System and the Daytime Running Lamps

(DRL) feature by following these steps. When the system is turned off, the headlights will not automatically come on when it becomes dark outside.

1. Turn the ignition to RUN.

2. Press the DOME OVERRIDE button four times within six seconds. After the fourth press of the button, a chime will sound informing you the system is off. The system will revert back to the automatic mode when the ignition is turned off and on again.

3. To return to the automatic mode, push the DOME

OVERRIDE button four times within six seconds

(the chime will sound), or turn the ignition off and on again.

As with any vehicle, you should turn on the regular headlamp system when you need it.

Compass Operation

With the ignition on, the compass will show two character boxes. The mirror will display the compass heading.

When cleaning the mirror, use a paper towel or similar material dampened with glass cleaner. Do not spray glass cleaner directly on the mirror as that may cause the liquid cleaner to enter the mirror housing.

Compass Calibration

The compass may need calibration if one of the following occurs:

D After five seconds, the display does not show a compass heading (N for North, for example), there may be a strong magnetic field interfering with the compass. Such interference may be caused by a magnetic antenna mount, magnetic note pad holder or a similar magnetic item.

D The compass does not display the correct heading and the compass zone variance is set correctly.

In order to calibrate, the letters CAL must be displayed in the mirror compass windows. If CAL is not displayed, push in the COMP button for approximately eight seconds or until the letters CAL are displayed.

The compass can be calibrated in one of two ways:

D Drive the vehicle in circles at five mph (8 km/h) or less until the display reads a direction, or

D drive the vehicle on your everyday routine and after several turns the compass will become calibrated and will display a direction.

Compass Variance

The mirror is set in zone eight upon leaving the factory.

It will be necessary to adjust the compass to compensate for compass variance if you live outside zone eight.

Under certain circumstances, as during a long distance cross country trip, it will be necessary to adjust for compass variance. Compass variance is the difference between earth’s magnetic north and true geographic north. If not adjusted to account for compass variance, your compass could give false readings.

To adjust for compass variance:

1. Use the COMP button located at the bottom of the mirror.

2. Press and hold the COMP button for three seconds until a zone number appears in the display.

3. Find your current location and variance zone number on the following zone map.

2-53

4. Press the COMP button on the bottom of the mirror until the new zone number appears in the display.

After you stop pressing the button in, the display will show a compass direction within a few seconds.

Warning Lights, Gages and Indicators

This part describes the warning lights and gages that may be on your vehicle. The pictures will help you locate them.

Warning lights and gages can signal that something is wrong before it becomes serious enough to cause an expensive repair or replacement. Paying attention to your warning lights and gages could also save you or others from injury.

Warning lights come on when there may be or is a problem with one of your vehicle’s functions. As you will see in the details on the next few pages, some warning lights come on briefly when you start the engine just to let you know they’re working. If you are familiar with this section, you should not be alarmed when this happens.

Gages can indicate when there may be or is a problem with one of your vehicle’s functions. Often gages and warning lights work together to let you know when there’s a problem with your vehicle.

2-73

When one of the warning lights comes on and stays on when you are driving, or when one of the gages shows there may be a problem, check the section that tells you what to do about it. Please follow this manual’s advice.

Waiting to do repairs can be costly - and even dangerous. So please get to know your warning lights and gages. They’re a big help.

Your vehicle also has a driver information system that works along with the warning lights and gages. See

“Message Center” in the Index.

Safety Belt Reminder Light

When the key is turned to RUN or START, a chime will come on for about six seconds to remind people to fasten their safety belts, unless the driver’s safety belt is already buckled.

The safety belt light will also come on and stay on for about 20 seconds, then it will flash for about 55 seconds.

Air Bag Readiness Light

There is an air bag readiness light on the instrument panel, which shows the air bag symbol. The system checks the air bag’s electrical system for malfunctions.

The light tells you if there is an electrical problem.

The system check includes the air bag sensors, the air bag modules, the wiring and the crash sensing and diagnostic module. For more information on the air bag system, see “Air Bag” in the Index.

This light will come on when you start your vehicle, and it will flash for a few seconds. Then the light should go out. This means the system is ready.

If the air bag readiness light stays on after you start the vehicle or comes on when you are driving, your air bag system may not work properly. Have your vehicle serviced right away.

If the driver’s belt is already buckled, neither the chime nor the light will come on.

2-74

Voltmeter

CAUTION:

If the air bag readiness light stays on after you start your vehicle, it means the air bag system may not be working properly. The air bags in your vehicle may not inflate in a crash, or they could even inflate without a crash. To help avoid injury to yourself or others, have your vehicle serviced right away if the air bag readiness light stays on after you start your vehicle.

The air bag readiness light should flash for a few seconds when you turn the ignition key to RUN. If the light doesn’t come on then, have it fixed so it will be ready to warn you if there is a problem.

United States Canada

When your engine is not running, but the ignition is in

RUN, this gage shows your battery’s state of charge in

DC volts.

When the engine is running, the gage shows the condition of the charging system. Readings between the low and high warning zones indicate the normal operating range.

2-75

Readings in the low warning zone may occur when a large number of electrical accessories are operating in the vehicle and the engine is left at an idle for an extended period. This condition is normal since the charging system is not able to provide full power at engine idle. As engine speeds are increased, this condition should correct itself as higher engine speeds allow the charging system to create maximum power.

You can only drive for a short time with the reading in either warning zone. If you must drive, turn off all unnecessary accessories.

Readings in either warning zone indicate a possible problem in the electrical system. Have the vehicle serviced as soon as possible.

Brake System Warning Light

With the ignition on, the brake system warning light will flash when you set the parking brake. The light will flash if the parking brake doesn’t release fully. If you try to drive with the parking brake engaged, a chime will sound when the vehicle speed is greater than 3 mph (5 km/h).

Your vehicle’s hydraulic brake system is divided into two parts. If one part isn’t working, the other part can still work and stop you. For good braking, though, you need both parts working well.

If the warning light comes on, there could be a brake problem. Have your brake system inspected right away.

United States Canada

2-76

This light should come on briefly when you turn the ignition key to RUN. If it doesn’t come on then, have it fixed so it will be ready to warn you if there’s a problem.

If the light comes on while you are driving, pull off the road and stop carefully. You may notice that the pedal is harder to push. Or, the pedal may go closer to the floor.

It may take longer to stop. If the light is still on, have the vehicle towed for service. See “Towing Your Vehicle” in the Index.

CAUTION:

Your brake system may not be working properly if the brake system warning light is on. Driving with the brake system warning light on can lead to an accident. If the light is still on after you’ve pulled off the road and stopped carefully, have the vehicle towed for service.

Anti-Lock Brake System Warning Light

With the anti lock brake system, this light will come on when you start your engine and may stay on for several seconds.

That’s normal.

If the light stays on, or comes on when you’re driving, your vehicle needs service. If the regular brake system warning light isn’t on, you still have brakes, but you don’t have anti lock brakes. If the regular brake system warning light is also on, you don’t have anti lock brakes and there’s a problem with your regular brakes. See

“Brake System Warning Light” earlier in this section.

The anti lock brake system warning light should come on briefly when you turn the ignition key to RUN. If the light doesn’t come on then, have it fixed so it will be ready to warn you if there is a problem.

2-77

Low Traction Light (If Equipped)

If you have the Traction

Assist System, this light will come on when the system is limiting wheel spin. See “Traction Assist

System” in the Index.

Traction Off Light (If Equipped)

If you have the Traction

Assist System, this light should come on briefly when you turn the ignition to RUN.

You may feel or hear the system working or notice a lack of accelerator response, but this is normal.

The LOW TRACTION light also comes on briefly when you turn your ignition to RUN. If the light doesn’t come on then, the system may require service; have it fixed so it will be there to tell you when the traction system is active. Slippery road conditions may exist if this light comes on, so adjust your driving accordingly.

If the light doesn’t come on then, the system may require service; have it fixed so it will be there to warn you if the system is turned off.

If the light stays on, or comes on when you’re driving, there may be a problem with your Traction Assist

System and your vehicle may need service. When this light is on, the system will not limit wheel spin. Adjust your driving accordingly.

2-78

The TRACTION OFF light may come on for the following reasons:

D If you turn the system off by pressing the TAS on/off button located to the left of the steering wheel, the light will come on and stay on. To turn the system back on, press the button again; the light should go off.

D If you move the shift lever to FIRST (1), the light will come on and stay on to indicate that the traction system is off. This is normal operation. To turn the system back on, move the shift lever back to a position other than FIRST (1); the light should go off. See “Traction Assist System” in the Index.

D The light will come on and stay on if the TAS automatic engagement feature has been turned off.

To turn the system on, press the TAS off/on button; the light should go off. To turn the automatic engagement feature back on, see “Traction Assist

System” in the Index.

D If the Traction Assist System is affected by an anti lock brake system, TAS or engine related problem, the system will turn off and the light will come on. Have your vehicle serviced.

D If the vehicle is driven over an extremely rough road, the system will turn off and the light will come on.

The light will go off a few seconds after the rough road conditions go away or when the vehicle comes to a complete stop. This is normal operation.

2-79

Engine Coolant Temperature Gage Transmission Temperature Gage

(If Equipped)

United States Canada

This gage shows the engine coolant temperature.

It also provides an indicator of how hard your vehicle is working. During a majority of the operation, the gage will read 210

_F (100_C) or less. If you are pulling a load or going up hills, it is normal for the temperature to fluctuate and approach the 250

_F (122_C) mark. If the gage reaches the 260

_F (125_C) mark, it indicates that the cooling system is working beyond its capacity.

See “Engine Overheating” in the Index.

United States Canada

Your vehicle may be equipped with a transmission temperature gage.

When your ignition is on, the gage shows the temperature of the transmission fluid. The normal operating range is from 100

_F (38_C) to about 265_F (130_C).

2-80

At approximately 265

_F (130_C), the message center will display a TRANS FLUID HOT message and the transmission will enter a transmission protection mode.

When the transmission enters the protection mode, you may notice a change in the transmission shifting patterns. The transmission will return to normal shifting patterns when the transmission fluid temperature falls below 260

_F (127_C).

See “Message Center” in the Index for further information.

If the transmission fluid reaches temperatures of approximately 275

_F (135_C) or greater, the message center will display a TRANS HOT...IDLE ENG warning message. Pull the vehicle off the roadway when it is safe to do so. Set the parking brake, place the transmission in

PARK (P) and allow the engine to idle until the transmission temperature falls below 260

_F (127_C).

If the transmission continues to operate above 265

_F

(130

_C), contact your nearest dealer or the GM

Roadside Assistance Center. See “Roadside Assistance” in the Index.

NOTICE:

If you keep driving your vehicle with the transmission temperature gage above the normal operating range, you can damage the transmission. This could lead to costly repairs that may not be covered under your warranty.

The following situations can cause the transmission to operate at higher temperatures:

D Towing a trailer

D Hot outside air temperatures

D Hauling a large or heavy load

D Low transmission fluid level

D High transmission fluid level

D Restricted air flow to the radiator and the auxiliary transmission oil cooler (if equipped).

A temporary solution to hotter transmission operating temperatures may be to let the transmission cool down.

If the transmission is operated at higher temperatures on a frequent basis, see “Scheduled Maintenance” in the

Index for the proper transmission maintenance intervals.

2-81

Malfunction Indicator Lamp (Service

Engine Soon Light in the United States or Check Engine Light in Canada)

United States Canada

Your vehicle is equipped with a computer which monitors operation of the fuel, ignition and emission control systems.

This system is called OBD II (On Board

Diagnostics Second Generation) and is intended to assure that emissions are at acceptable levels for the life of the vehicle, helping to produce a cleaner environment. The

SERVICE ENGINE SOON or CHECK ENGINE light comes on to indicate that there is a problem and service is required. Malfunctions often will be indicated by the system before any problem is apparent. This may prevent more serious damage to your vehicle. This system is also designed to assist your service technician in correctly diagnosing any malfunction.

NOTICE:

If you keep driving your vehicle with this light on, after a while, your emission controls may not work as well, your fuel economy may not be as good and your engine may not run as smoothly.

This could lead to costly repairs that may not be covered by your warranty.

2-82

NOTICE:

Modifications made to the engine, transmission, exhaust, intake or fuel system of your vehicle or the replacement of the original tires with other than those of the same Tire Performance Criteria

(TPC) can affect your vehicle’s emission controls and may cause the SERVICE ENGINE SOON or

CHECK ENGINE light to come on.

Modifications to these systems could lead to costly repairs not covered by your warranty. This may also result in a failure to pass a required

Emission Inspection/Maintenance test.

This light should come on, as a check to show you it is working, when the ignition is on and the engine is not running. If the light doesn’t come on, have it repaired.

This light will also come on during a malfunction in one of two ways:

D Light Flashing - A misfire condition has been detected. A misfire increases vehicle emissions and may damage the emission control system on your vehicle. Dealer or qualified service center diagnosis and service may be required.

D Light On Steady - An emission control system malfunction has been detected on your vehicle. Dealer or qualified service center diagnosis and service may be required.

2-83

If the Light Is Flashing

The following may prevent more serious damage to your vehicle:

D Reducing vehicle speed.

D Avoiding hard accelerations.

D Avoiding steep uphill grades.

D If you are towing a trailer, reduce the amount of cargo being hauled as soon as it is possible.

If the light stops flashing and remains on steady, see “If the Light Is On Steady” following.

If the light continues to flash, when it is safe to do so,

stop the vehicle. Find a safe place to park your vehicle.

Turn the key off, wait at least 10 seconds and restart the engine. If the light remains on steady, see “If the Light

Is On Steady” following. If the light is still flashing, follow the previous steps, and drive the vehicle to your dealer or qualified service center for service.

If the Light Is On Steady

You may be able to correct the emission system malfunction by considering the following:

Did you recently put fuel into your vehicle?

If so, reinstall the fuel cap, making sure to fully install the cap. See “Filling Your Tank” in the Index. The diagnostic system can determine if the fuel cap has been left off or improperly installed. A loose or missing fuel cap will allow fuel to evaporate into the atmosphere. A few driving trips with the cap properly installed should turn the light off.

Did you just drive through a deep puddle of water?

If so, your electrical system may be wet. The condition will usually be corrected when the electrical system dries out. A few driving trips should turn the light off.

2-84

Have you recently changed brands of fuel?

If so, be sure to fuel your vehicle with quality fuel. See

“Fuel” in the Index. Poor fuel quality will cause your engine not to run as efficiently as designed. You may notice this as stalling after start up, stalling when you put the vehicle into gear, misfiring, hesitation on acceleration or stumbling on acceleration. (These conditions may go away once the engine is warmed up.)

This will be detected by the system and cause the light to turn on.

If you experience one or more of these conditions, change the fuel brand you use. It will require at least one full tank of the proper fuel to turn the light off.

If none of the above steps have made the light turn off, have your dealer or qualified service center check the vehicle. Your dealer has the proper test equipment and diagnostic tools to fix any mechanical or electrical problems that may have developed.

Emissions Inspection and Maintenance Programs

Some state/provincial and local governments have or may begin programs to inspect the emission control equipment on your vehicle. Failure to pass this inspection could prevent you from getting a vehicle registration.

Here are some things you need to know in order to help your vehicle pass an inspection:

Your vehicle will not pass this inspection if the

SERVICE ENGINE SOON or CHECK ENGINE light is on or not working properly.

Your vehicle will not pass this inspection if the OBD

(on board diagnostic) system determines that critical emission control systems have not been completely diagnosed by the system. The vehicle would be considered not ready for inspection. This can happen if you have recently replaced your battery or if your battery has run down. The diagnostic system is designed to evaluate critical emission control systems during normal driving. This may take several days of routine driving. If you have done this and your vehicle still does not pass the inspection for lack of OBD system readiness, see your dealer or qualified service center to prepare the vehicle for inspection.

2-85

Oil Pressure Gage

United States Canada

The oil pressure gage shows the engine oil pressure in psi (pounds per square inch) when the engine is running.

Canadian vehicles indicate pressure in kPa (kilopascals).

Oil pressure may vary with engine speed, outside temperature and oil viscosity, but readings above the low pressure zone indicate the normal operating range.

A reading in the low pressure zone may be caused by a dangerously low oil level or some other problem causing low oil pressure. Check your oil as soon as possible. See “Check Eng Oil Pressure” and “Engine

Oil” in the Index.

CAUTION:

Don’t keep driving if the oil pressure is low.

If you do, your engine can become so hot that it catches fire. You or others could be burned.

Check your oil as soon as possible and have your vehicle serviced.

NOTICE:

Damage to your engine from neglected oil problems can be costly and is not covered by your warranty.

Tow/Haul Light

This message is displayed when the tow/haul mode has been activated.

United States Canada

The fuel gage, when the ignition is on, tells you about how much fuel you have left in your tank.

The gage will first indicate empty before you are out of fuel, and you should get more fuel as soon as possible.

When the fuel tank is low the Low Fuel message will appear. See “Message Center” in the Index.

For more information, see “Tow/Haul Mode” in the Index.

2-87

Here are some situations you may experience with your fuel gage. None of these indicate a problem with the fuel gage.

D At the gas station, the fuel pump shuts off before the gage reads full.

D It takes a little more or less fuel to fill up than the fuel gage indicated. For example, the gage may have indicated the tank was half full, but it actually took a little more or less than half the tank’s capacity to fill the tank.

D The gage goes back to empty when you turn off the ignition.

Message Center

The message center is located on the left side of the instrument panel cluster. It gives you important safety and maintenance facts. When you turn the ignition on, the entire center lights up for just a few seconds. As needed, the message center will display one of the following messages. The message center is capable of alternating among different messages if needed.

Battery

If this message is displayed when the engine is running, you may have a problem with your charging system.

The battery display will also stay on while the key is in

RUN until the engine is started.

If the message stays on after starting the engine it could indicate a problem with the generator drive belt, or some other charging system problem. Have it checked right away. Driving with this message displayed could drain your battery.

If you must drive a short distance with this message displayed, it helps to turn off all your accessories, such as the radio and the air conditioner.

2-88

Trans Fluid Hot

If you have an automatic transmission, you have a transmission temperature warning display contained in the message center.

If the transmission fluid temperature becomes high, the message will be displayed.

When the transmission enters the protection mode, you may notice a change in the transmission shifting patterns. When the transmission fluid temperature returns to normal, the display will turn off and the transmission shifting patterns will return to normal.

NOTICE:

If you keep driving your vehicle with the transmission TRANS FLUID HOT message displayed, you can damage the transmission.

This could lead to costly repairs that may not be covered under your warranty.

Manual Operation

The right knob on the control panel allows you to choose the direction of air delivery.

You can choose to set the climate control system yourself, or let the system work for you by placing the system in AUTO mode. See “Mode Knob - Automatic

Operation” later in this section.

(Vent): This setting directs most of the air through the instrument panel outlets and a small amount through the floor outlets.

(Bi Level): Air is delivered through the floor outlets as well as the instrument panel outlets.

(Floor): This setting directs most of the warmed air through the floor outlets and some air through the windshield defroster outlets.

(Blend): Airflow is divided equally between the floor outlet and the windshield defroster outlets. The air conditioning compressor may run to dehumidify the air to prevent window fogging.

3-6

(Defrost): This setting directs most of the air through the windshield defroster outlets with air flow also delivered from the side window and floor outlets.

When in defrost mode, the air conditioning compressor may run to assist in dehumidifying the air and limit window fogging.

Mode Buttons

(Outside Air): Press this button to force the system to use outside air. Press is again to close off the outside air.

Pressing the outside air button will cancel the recirculation button.

(Recirculation): Press this button to limit the amount of outside air entering your vehicle. This is helpful when you are trying to limit odors entering your vehicle or attempting to quickly cool down the interior.

Mode Knob

--

Automatic Operation

When the system is set for automatic operation, sensors will control the air delivery mode. Air will come primarily from the floor or instrument panel outlets, with some air directed to the windshield to prevent fogging.

When the system is in AUTO mode, the air conditioning light will turn on, and the recirculation and outside air lights turn off. With the system in full auto control

(both the fan and mode knobs in AUTO), you still have the ability to override any function. However, continually overriding the outside air or the A/C compressor will limit the ability of the system to cool the vehicle quickly.

3-7

If you push a button for a function which is not available, the light next to that button will flash three times to alert you that it’s not available.

To find your comfort zone, start with the 74

_F (23_C) setting and allow about 20 minutes for the system to adjust the temperature if necessary.

With the automatic setting, the air conditioning compressor automatically cycles when needed to cool the air. In cold weather, when the system senses the need for heat, the airflow will be directed out of the floor outlets. As the interior temperature approaches a desired setting, the fan speed will decrease. To maintain interior comfort, the airflow will adjust between the instrument panel air outlets and floor outlets. On bright sunny days in cool weather, the airflow may come out of the air conditioning and floor outlets (bi level mode) to maintain comfort and prevent stuffiness.

To avoid blowing cold air in cold weather, the system will delay turning on the fan until warm air is available. The length of delay depends on the outside air temperature, engine coolant temperature or the time since the engine was last started. As the coolant warms up, the fan speed will gradually increase and air will flow from the floor outlets, with some airflow to the windshield to prevent fogging under most normal conditions.

Be careful not to put anything over the solar sensor located around the center of the instrument panel.

This sensor is used by the automatic system to regulate temperature.

Air Conditioning

On hot days, open the windows long enough to let hot air inside escape. This reduces the time it takes for your vehicle to cool down. Then keep your windows closed for the air conditioner to work its best.

The A/C button, below the mode knob, allows the air coming into your vehicle to be cooled. This setting is useful for normal cooling on hot days.

The recirculation button allows the air inside your vehicle to be recirculated. This setting helps to maximize your air conditioner’s performance and your vehicle’s fuel economy. This setting also cools air the fastest and can be used to keep unwanted odors and/or dust from entering the vehicle. When using the air conditioner, turn off the recirculation button after the vehicle reaches a comfortable interior temperature.

When the right knob on the control panel is between floor and defrost, the recirculation feature will not function to reduce window fogging.

When you use A/C with the recirculation button pushed in, turn off recirculation as soon as the vehicle reaches a comfortable interior temperature.

Maximum air conditioning performance is obtained by pressing the A/C button, the recirculation button and turning the temperature knob fully counterclockwise to the blue area. This setting also cools air the fastest. After the vehicle’s interior reaches a comfortable temperature, press the outside air button to place the air conditioning system in the normal mode.

Passenger Compartment Air Filter (If Equipped)

If your vehicle has air conditioning, it is equipped with a passenger compartment air filter, which filters outside air entering the vehicle. For information on replacing the filter see “Passenger Compartment Air Filter” in the Index.

3-13

Heating

The heater works best if you keep your windows closed while using it. On cold days, use the floor or bi level setting with the temperature knob in the red area.

On cold days, approximately 32

_F ( 0

_C) or lower, if your vehicle is equipped with an automatic transmission, you may experience differences in how the transmission shifts until the engine is warm. This feature automatically reduces the time it takes for the engine to reach normal operating temperature and shortens the time it takes the heater to reach full output.

If you use the engine coolant heater before starting your engine in cold weather, 20

_F ( 8

_C) or lower, the heating system will produce warmer air faster to heat the passenger compartment.

The use of an engine coolant heater also reduces the time it takes for the engine to reach normal operating temperature. For more information, see “Engine Coolant

Heater” in the Index.

Defogging and Defrosting

On cool, humid days, use defrost setting to keep the windshield and side windows clear. Use the defrost setting to remove fog or ice from the windshield in extremely humid or cold conditions. Use the defrost setting with the temperature knob toward the red area and the fan control turned all the way to the right.

Rear Window Defogger (If Equipped)

If you see lines running across the rear window, you have a rear window defogger. The lines warm the glass.

To turn on the rear window defogger, press this button next to the fan knob.

The rear window defogger will only work if the ignition is in RUN. For best results, clear the window of as much snow or ice as possible.

3-14

The defogger will shut itself off after several minutes. If you need additional warming time, press the button again. You can turn the defogger off at any time by pressing the button.

If your vehicle is equipped with heated outside mirrors, the rear window defogger button will also activate the heated outside mirrors.

Do not attach a temporary vehicle license, tape or decals across the defogger grid on the rear window.

NOTICE:

Don’t use a razor blade or something else sharp on the inside of the rear window. If you do, you could cut or damage the warming grid, and the repairs wouldn’t be covered by your warranty.

Ventilation System

For mild outside temperatures when little heating or cooling is needed, use the vent setting to direct outside air through your vehicle.

Your vehicle’s ventilation system supplies outside air to the inside of your vehicle when it is moving. With the side windows closed, air will flow into the front air inlet grilles, through the vehicle, and out the air exhaust valves.

Outside air will also enter the vehicle when the heater or the air conditioning fan is running, unless you have the recirculation button pushed in. For more information on the recirculation button, see “Air Conditioning” earlier in this section.

3-15

Your vehicle has air outlets in the center and on the sides of your instrument panel.

You can turn the outlets from side to side or up and down to direct the flow of air. The left driver and passenger outlets on vehicles equipped with air conditioning have shut off knobs. Turn the knob to the left to shut off air flow or to the right to allow air flow.

When you close an outlet, it will increase the flow of air coming out of any outlets that are open. The center outlet does not completely shut off airflow.

Ventilation Tips

D Keep the hood and front air inlet free of ice, snow or any other obstruction (such as leaves). The heater and defroster will work far better, reducing the chance of fogging the inside of your windows.

D When you enter a vehicle in cold weather, turn the fan knob all the way to the right for a few moments before driving. This helps clear the intake ducts of snow and moisture, and reduces the chance of fogging the inside of your windows.

D Keep the air path under the front seats clear of objects. This helps air to circulate throughout your vehicle.

D The use of hood air deflectors may adversely affect the performance of the heating and air conditioning system.

Theft-Deterrent Feature (If Equipped)

THEFTLOCK

R

is designed to discourage theft of your radio. It works by using a secret code to disable all radio functions whenever battery power is removed.

The THEFTLOCK feature for the radio may be used or ignored. If ignored, the system plays normally and the radio is not protected by the feature. If THEFTLOCK is activated, your radio will not operate if stolen.

When THEFTLOCK is activated, the radio will display

LOC to indicate a locked condition anytime battery power has been interrupted. If your battery loses power for any reason, you must unlock the radio with the secret code before it will operate.

Activating the Theft

Understanding Radio Reception

AM

The range for most AM stations is greater than for FM, especially at night. The longer range, however, can cause stations to interfere with each other. AM can pick up noise from things like storms and power lines. Try reducing the treble to reduce this noise if you ever get it.

FM Stereo

FM stereo will give you the best sound, but FM signals will reach only about 10 to 40 miles (16 to 65 km). Tall buildings or hills can interfere with FM signals, causing the sound to come and go.

Tips About Your Audio System

Hearing damage from loud noise is almost undetectable until it is too late. Your hearing can adapt to higher volumes of sound. Sound that seems normal can be loud and harmful to your hearing. Take precautions by adjusting the volume control on your radio to a safe sound level before your hearing adapts to it.

To help avoid hearing loss or damage do the following:

1. Adjust the volume control to the lowest setting.

2. Increase volume slowly until you hear comfortably and clearly.

3-29

NOTICE:

Before you add any sound equipment to your vehicle - like a tape player, CB radio, mobile telephone or two way radio - be sure you can add what you want. If you can, it’s very important to do it properly. Added sound equipment may interfere with the operation of your vehicle’s engine, Delphi Electronics radio or other systems, and even damage them.

Your vehicle’s systems may interfere with the operation of sound equipment that has been added improperly.

So, before adding sound equipment, check with your dealer and be sure to check federal rules covering mobile radio and telephone units.

Care of Your Compact Discs

Handle discs carefully. Store them in their original cases or other protective cases and away from direct sunlight and dust. If the surface of a disc is soiled, dampen a clean, soft cloth in a mild, neutral detergent solution and clean it, wiping from the center to the edge.

Be sure never to touch the signal surface when handling discs. Pick up discs by grasping the outer edges or the edge of the hole and the outer edge.

Care of Your Compact Disc Player

The use of CD lens cleaner discs is not advised, due to the risk of contaminating the lens of the CD optics with lubricants internal to the CD mechanism.

Cleaning Your Remote Cassette Tape Player

Your remote tape player should be cleaned regularly after every 50 hours of use. Your radio may display

CLN to indicate that you have used your remote cassette tape player for 50 hours without resetting the tape clean timer. If this message appears on the display, your remote cassette player needs to be cleaned. It will still play tapes, but you should clean it as soon as possible to prevent damage to your tapes and player.

3-30

The recommended cleaning method for your remote cassette tape player is the use of a scrubbing action, non abrasive cleaning cassette with pads, which scrub the tape head as the hubs of the cleaner cassette turn.

The recommended cleaning cassette is available through your dealer (GM Part No. 12344789).

When cleaning the cassette tape player with the recommended non abrasive cleaning casette, it is possible that the cassette may eject, because the cut tape detection feature on your tape player may recognize it as a broken tape.

Use the following procedure to clean your remote cassette tape player.

1. Turn the radio on.

2. Insert the recommended cleaning cassette.

3. If the cleaning cassette ejects, insert the cassette at least three times to ensure thorough cleaning.

4. Eject the cleaning cassette if it does not eject on its own.

After you clean the remote cassette tape player, press and hold the RECALL button on the radio until CLN appears on the radio display. While still pressing the

RECALL button, press the EJECT button on the remote cassette tape player. Release both buttons when the radio displays --, indicating that the CLN indicator has been reset.

Fixed Mast Antenna

The fixed mast antenna can withstand most car washes without being damaged. If the mast should ever become slightly bent, you can straighten it out by hand. If the mast is badly bent, as it might be by vandals, you should replace it.

Check every once in a while to be sure the mast is still tightened to the cowl. If tightening is required, tighten by hand, then with a wrench one quarter turn.

Defensive Driving

The best advice anyone can give about driving is:

Drive defensively.

Please start with a very important safety device in your vehicle: Buckle up. See “Safety Belts” in the Index.

Defensive driving really means “be ready for anything.”

On city streets, rural roads or freeways, it means

“always expect the unexpected.”

Assume that pedestrians or other drivers are going to be careless and make mistakes. Anticipate what they might do. Be ready for their mistakes.

Rear end collisions are about the most preventable of accidents. Yet they are common. Allow enough following distance. It’s the best defensive driving maneuver, in both city and rural driving. You never know when the vehicle in front of you is going to brake or turn suddenly.

Defensive driving requires that a driver concentrate on the driving task. Anything that distracts from the driving task - such as concentrating on a cellular telephone call, reading, or reaching for something on the floor - makes proper defensive driving more difficult and can even cause a collision, with resulting injury. Ask a passenger to help do things like this, or pull off the road in a safe place to do them yourself.

These simple defensive driving techniques could save your life.

4-2

Drunken Driving

Death and injury associated with drinking and driving is a national tragedy. It’s the number one contributor to the highway death toll, claiming thousands of victims every year.

Alcohol affects four things that anyone needs to drive a vehicle:

D Judgment

D Muscular Coordination

D Vision

D Attentiveness.

Police records show that almost half of all motor vehicle related deaths involve alcohol. In most cases, these deaths are the result of someone who was drinking and driving. In recent years, about 16,000 annual motor vehicle related deaths have been associated with the use of alcohol, with more than 300,000 people injured.

Many adults - by some estimates, nearly half the adult population - choose never to drink alcohol, so they never drive after drinking. For persons under 21, it’s against the law in every U.S. state to drink alcohol.

There are good medical, psychological and developmental reasons for these laws.

The obvious way to solve the leading highway safety problem is for people never to drink alcohol and then drive. But what if people do? How much is “too much” if the driver plans to drive? It’s a lot less than many might think. Although it depends on each person and situation, here is some general information on the problem.

The Blood Alcohol Concentration (BAC) of someone who is drinking depends upon four things:

D The amount of alcohol consumed

D The drinker’s body weight

D The amount of food that is consumed before and during drinking

D The length of time it has taken the drinker to consume the alcohol.

According to the American Medical Association, a

180 lb. (82 kg) person who drinks three 12 ounce

(355 ml) bottles of beer in an hour will end up with a

BAC of about 0.06 percent. The person would reach the same BAC by drinking three 4 ounce (120 ml) glasses of wine or three mixed drinks if each had 1 1/2 ounces

(45 ml) of a liquor like whiskey, gin or vodka.

4-3

It’s the amount of alcohol that counts. For example, if the same person drank three double martinis (3 ounces or 90 ml of liquor each) within an hour, the person’s

BAC would be close to 0.12 percent. A person who consumes food just before or during drinking will have a somewhat lower BAC level.

There is a gender difference, too. Women generally have a lower relative percentage of body water than men.

Since alcohol is carried in body water, this means that a woman generally will reach a higher BAC level than a man of her same body weight when each has the same number of drinks.

The law in an increasing number of U.S. states, and throughout Canada, sets the legal limit at 0.08 percent.

In some other countries, the limit is even lower.

For example, it is 0.05 percent in both France and

Germany. The BAC limit for all commercial drivers in the United States is 0.04 percent.

The BAC will be over 0.10 percent after three to six drinks (in one hour). Of course, as we’ve seen, it depends on how much alcohol is in the drinks, and how quickly the person drinks them.

But the ability to drive is affected well below a BAC of

0.10 percent. Research shows that the driving skills of many people are impaired at a BAC approaching

0.05 percent, and that the effects are worse at night.

All drivers are impaired at BAC levels above 0.05 percent.

Statistics show that the chance of being in a collision increases sharply for drivers who have a BAC of

0.05 percent or above. A driver with a BAC level of

0.06 percent has doubled his or her chance of having a collision. At a BAC level of 0.10 percent, the chance of this driver having a collision is 12 times greater; at a level of 0.15 percent, the chance is 25 times greater!

4-4

The body takes about an hour to rid itself of the alcohol in one drink. No amount of coffee or number of cold showers will speed that up. “I’ll be careful” isn’t the right answer. What if there’s an emergency, a need to take sudden action, as when a child darts into the street?

A person with even a moderate BAC might not be able to react quickly enough to avoid the collision.

There’s something else about drinking and driving that many people don’t know. Medical research shows that alcohol in a person’s system can make crash injuries worse, especially injuries to the brain, spinal cord or heart. This means that when anyone who has been drinking - driver or passenger - is in a crash, that person’s chance of being killed or permanently disabled is higher than if the person had not been drinking.

CAUTION:

Drinking and then driving is very dangerous.

Your reflexes, perceptions, attentiveness and judgment can be affected by even a small amount of alcohol. You can have a serious - or even fatal - collision if you drive after drinking.

Please don’t drink and drive or ride with a driver who has been drinking. Ride home in a cab; or if you’re with a group, designate a driver who will not drink.

4-5

Control of a Vehicle

You have three systems that make your vehicle go where you want it to go. They are the brakes, the steering and the accelerator. All three systems have to do their work at the places where the tires meet the road.

Braking

Braking action involves perception time and reaction time.

First, you have to decide to push on the brake pedal.

That’s perception time. Then you have to bring up your foot and do it. That’s reaction time.

Average reaction time is about 3/4 of a second. But that’s only an average. It might be less with one driver and as long as two or three seconds or more with another. Age, physical condition, alertness, coordination and eyesight all play a part. So do alcohol, drugs and frustration. But even in 3/4 of a second, a vehicle moving at 60 mph (100 km/h) travels 66 feet (20 m).

That could be a lot of distance in an emergency, so keeping enough space between your vehicle and others is important.

And, of course, actual stopping distances vary greatly with the surface of the road (whether it’s pavement or gravel); the condition of the road (wet, dry, icy); tire tread; the condition of your brakes; the weight of the vehicle and the amount of brake force applied.

Sometimes, as when you’re driving on snow or ice, it’s easy to ask more of those control systems than the tires and road can provide. That means you can lose control of your vehicle. Also see “Traction Assist System” in the Index.

4-6

Avoid needless heavy braking. Some people drive in spurts - heavy acceleration followed by heavy braking - rather than keeping pace with traffic. This is a mistake. Your brakes may not have time to cool between hard stops. Your brakes will wear out much faster if you do a lot of heavy braking. If you keep pace with the traffic and allow realistic following distances, you will eliminate a lot of unnecessary braking. That means better braking and longer brake life.

If your engine ever stops while you’re driving, brake normally but don’t pump your brakes. If you do, the pedal may get harder to push down. If your engine stops, you will still have some power brake assist. But you will use it when you brake. Once the power assist is used up, it may take longer to stop and the brake pedal will be harder to push.

Anti-Lock Brake System (ABS)

Your vehicle has anti lock brakes. ABS is an advanced electronic braking system that will help prevent a braking skid.

When you start your engine and begin to drive away, your anti lock brake system will check itself. You may hear a momentary motor or clicking noise while this test is going on. This is normal.

If there’s a problem with the anti lock brake system, this warning light will stay on.

See “Anti Lock Brake

System Warning Light” in the Index.

4-7

The anti lock system can change the brake pressure faster than any driver could. The computer is programmed to make the most of available tire and road conditions. This can help you steer around the obstacle while braking hard.

Let’s say the road is wet and you’re driving safely.

Suddenly, an animal jumps out in front of you. You slam on the brakes and continue braking. Here’s what happens with ABS:

A computer senses that wheels are slowing down. If one of the wheels is about to stop rolling, the computer will separately work the brakes at each front wheel and at both rear wheels.

As you brake, your computer keeps receiving updates on wheel speed and controls braking pressure accordingly.

4-8

Remember: Anti lock doesn’t change the time you need to get your foot up to the brake pedal or always decrease stopping distance. If you get too close to the vehicle in front of you, you won’t have time to apply your brakes if that vehicle suddenly slows or stops. Always leave enough room up ahead to stop, even though you have anti lock brakes.

Using Anti

-

Lock

Don’t pump the brakes. Just hold the brake pedal down firmly and let anti lock work for you. You may feel the brakes vibrate, or you may notice some noise, but this is normal.

Braking in Emergencies

With anti lock, you can steer and brake at the same time. In many emergencies, steering can help you more than even the very best braking.

Traction Assist System (TAS) (Option)

Your vehicle may have a Traction Assist System (TAS) that limits wheel spin. This is especially useful in slippery road conditions. The system operates only if it senses that one or both of the rear wheels are spinning or beginning to lose traction. When this happens, the system reduces engine power to limit wheel spin.

This light will come on when the TAS is limiting wheel spin. See “Low

Traction Light” in the Index.

You may hear or feel the system working or notice a lack of accelerator response, but this is normal.

4-9

The Traction Assist System may operate on dry roads under some conditions. When this happens, you may notice a reduction in acceleration. This is normal and doesn’t mean there’s a problem with your vehicle.

Examples of these conditions include a hard acceleration in a turn, an abrupt upshift or downshift of the transmission or driving on rough roads.

If your vehicle is in cruise control when the TAS begins to limit wheel spin, the cruise control will automatically disengage. When road conditions allow you to safely use it again, you may re engage the cruise control. See

“Cruise Control” in the Index.

When the TRACTION

OFF light is on, the TAS is off and will not limit wheel spin. Adjust your driving accordingly.

The TRACTION OFF light will come on under the following conditions:

D The Traction Assist System is turned off, either by pressing the TAS on/off button or turning off the automatic engagement feature of the TAS.

D The transmission is in FIRST (1); TAS will not operate in this gear. This is normal.

D The vehicle is driven on an extremely rough road.

When the vehicle leaves the rough surface, slows down or stops, the light will go off and TAS will be on again. This is normal.

D A Traction Assist System, Anti Lock Brake System or engine related problem has been detected and the vehicle needs service.

See “Traction Off Light” in the Index.

4-10

The Traction Assist System, as delivered from the factory, will automatically come on whenever you start your vehicle. To limit wheel spin, especially in slippery road conditions, you should always leave the system on.

But you can turn the TAS off if you ever need to. You should turn the TAS off if your vehicle ever gets stuck in sand, mud or snow and rocking the vehicle is required.

See “Rocking Your Vehicle” in the Index.

To turn the system on or off press the TAS on/off button located to the left of the steering wheel on the instrument panel.

If you used the button to turn the system off, the

TRACTION OFF light will come on and stay on.

You can turn the system back on at any time by pressing the button again. The TRACTION OFF light should go off.

If desired, you can change the TAS automatic engagement feature so that the system will not come on automatically when the engine is started. To do so:

1. Park the vehicle with the ignition off and the transmission in PARK (P).

2. Turn the ignition to RUN; do not start the engine.

3. Apply the brake pedal, press the accelerator pedal to the floor and then press the TAS on/off button and hold it down for at least six seconds.

4. Release the TAS button and both pedals.

5. Turn off the ignition and wait a few seconds.

The next time you start your vehicle, the TAS will not automatically come on. You can restore the automatic feature by using the same procedure. Whether the TAS is set to come on automatically or not, you can always turn the system on or off by pressing the TAS on/off button.

4-11

Steering

Power Steering

If you lose power steering assist because the engine stops or the system is not functioning, you can steer but it will take much more effort.

Speed-Sensitive Steering (If Equipped)

This system varies the amount of steering effort proportionate to your vehicle speed. Steering is easier at lower speeds for maneuvering and parking ease. As your vehicle speed increases, the steering effort also increases. At highway speeds, the amount of steering effort is increased.

Steering Tips

Driving on Curves

It’s important to take curves at a reasonable speed.

A lot of the “driver lost control” accidents mentioned on the news happen on curves. Here’s why:

Experienced driver or beginner, each of us is subject to the same laws of physics when driving on curves. The traction of the tires against the road surface makes it possible for the vehicle to change its path when you turn the front wheels. If there’s no traction, inertia will keep the vehicle going in the same direction. If you’ve ever tried to steer a vehicle on wet ice, you’ll understand this.

The traction you can get in a curve depends on the condition of your tires and the road surface, the angle at which the curve is banked, and your speed. While you’re in a curve, speed is the one factor you can control.

4-12

Suppose you’re steering through a sharp curve.

Then you suddenly accelerate. Both control systems - steering and acceleration - have to do their work where the tires meet the road. Adding the sudden acceleration can demand too much of those places. You can lose control. Refer to “Traction Assist

System” in the Index.

What should you do if this ever happens? Ease up on the accelerator pedal, steer the vehicle the way you want it to go, and slow down.

Speed limit signs near curves warn that you should adjust your speed. Of course, the posted speeds are based on good weather and road conditions. Under less favorable conditions you’ll want to go slower.

If you need to reduce your speed as you approach a curve, do it before you enter the curve, while your front wheels are straight ahead.

Try to adjust your speed so you can “drive” through the curve. Maintain a reasonable, steady speed. Wait to accelerate until you are out of the curve, and then accelerate gently into the straightaway.

Steering in Emergencies

There are times when steering can be more effective than braking. For example, you come over a hill and find a truck stopped in your lane, or a car suddenly pulls out from nowhere, or a child darts out from between parked cars and stops right in front of you. You can avoid these problems by braking - if you can stop in time. But sometimes you can’t; there isn’t room.

That’s the time for evasive action - steering around the problem.

Your vehicle can perform very well in emergencies like these. First apply your brakes. See “Braking in

Emergencies” earlier in this section. It is better to remove as much speed as you can from a possible collision. Then steer around the problem, to the left or right depending on the space available.

4-13

Road Recovery

You may find that your right wheels have dropped off the edge of a road onto the shoulder while you’re driving.

An emergency like this requires close attention and a quick decision. If you are holding the steering wheel at the recommended 9 and 3 o’clock positions, you can turn it a full 180 degrees very quickly without removing either hand. But you have to act fast, steer quickly, and just as quickly straighten the wheel once you have avoided the object.

The fact that such emergency situations are always possible is a good reason to practice defensive driving at all times and wear safety belts properly.

If the level of the shoulder is only slightly below the pavement, recovery should be fairly easy. Ease off the accelerator and then, if there is nothing in the way, steer so that your vehicle straddles the edge of the pavement.

You can turn the steering wheel up to one quarter turn until the right front tire contacts the pavement edge.

Then turn your steering wheel to go straight down the roadway.

4-14

Passing

The driver of a vehicle about to pass another on a two lane highway waits for just the right moment, accelerates, moves around the vehicle ahead, then goes back into the right lane again. A simple maneuver?

Not necessarily! Passing another vehicle on a two lane highway is a potentially dangerous move, since the passing vehicle occupies the same lane as oncoming traffic for several seconds. A miscalculation, an error in judgment, or a brief surrender to frustration or anger can suddenly put the passing driver face to face with the worst of all traffic accidents - the head on collision.

So here are some tips for passing:

D “Drive ahead.” Look down the road, to the sides and to crossroads for situations that might affect your passing patterns. If you have any doubt whatsoever about making a successful pass, wait for a better time.

D Watch for traffic signs, pavement markings and lines.

If you can see a sign up ahead that might indicate a turn or an intersection, delay your pass. A broken center line usually indicates it’s all right to pass

(providing the road ahead is clear). Never cross a solid line on your side of the lane or a double solid line, even if the road seems empty of approaching traffic.

D Do not get too close to the vehicle you want to pass while you’re awaiting an opportunity. For one thing, following too closely reduces your area of vision, especially if you’re following a larger vehicle. Also, you won’t have adequate space if the vehicle ahead suddenly slows or stops. Keep back a reasonable distance.

D When it looks like a chance to pass is coming up, start to accelerate but stay in the right lane and don’t get too close. Time your move so you will be increasing speed as the time comes to move into the other lane. If the way is clear to pass, you will have a

“running start” that more than makes up for the distance you would lose by dropping back. And if something happens to cause you to cancel your pass, you need only slow down and drop back again and wait for another opportunity.

D If other cars are lined up to pass a slow vehicle, wait your turn. But take care that someone isn’t trying to pass you as you pull out to pass the slow vehicle.

Remember to glance over your shoulder and check the blind spot.

4-15

D Check your mirrors, glance over your shoulder and start your left lane change signal before moving out of the right lane to pass. When you are far enough ahead of the passed vehicle to see its front in your inside mirror, activate your right lane change signal and move back into the right lane. (Remember that if your right outside mirror is convex, the vehicle you just passed may seem to be farther away from you than it really is.)

D Try not to pass more than one vehicle at a time on two lane roads. Reconsider before passing the next vehicle.

D Don’t overtake a slowly moving vehicle too rapidly.

Even though the brake lamps are not flashing, it may be slowing down or starting to turn.

D If you’re being passed, make it easy for the following driver to get ahead of you. Perhaps you can ease a little to the right.

Loss of Control

Let’s review what driving experts say about what happens when the three control systems (brakes, steering and acceleration) don’t have enough friction where the tires meet the road to do what the driver has asked.

In any emergency, don’t give up. Keep trying to steer and constantly seek an escape route or area of less danger.

Skidding

In a skid, a driver can lose control of the vehicle.

Defensive drivers avoid most skids by taking reasonable care suited to existing conditions, and by not “overdriving” those conditions. But skids are always possible.

The three types of skids correspond to your vehicle’s three control systems. In the braking skid, your wheels aren’t rolling. In the steering or cornering skid, too much speed or steering in a curve causes tires to slip and lose cornering force. And in the acceleration skid, too much throttle causes the driving wheels to spin.

4-16

A cornering skid and an acceleration skid are best handled by easing your foot off the accelerator pedal.

A cornering skid is best handled by easing your foot off the accelerator pedal. If you have the “Traction Assist

System,” remember: It helps avoid only the acceleration skid. If you do not have this system, or if the system is off, then an acceleration skid is also best handled by easing your foot off the accelerator pedal.

If your vehicle starts to slide, ease your foot off the accelerator pedal and quickly steer the way you want the vehicle to go. If you start steering quickly enough, your vehicle may straighten out. Always be ready for a second skid if it occurs.

Of course, traction is reduced when water, snow, ice, gravel or other material is on the road. For safety, you’ll want to slow down and adjust your driving to these conditions. It is important to slow down on slippery surfaces because stopping distance will be longer and vehicle control more limited.

While driving on a surface with reduced traction, try your best to avoid sudden steering, acceleration or braking (including engine braking by shifting to a lower gear). Any sudden changes could cause the tires to slide. You may not realize the surface is slippery until your vehicle is skidding. Learn to recognize warning clues - such as enough water, ice or packed snow on the road to make a “mirrored surface” - and slow down when you have any doubt.

Remember: Any anti lock brake system (ABS) helps avoid only the braking skid.

Drive Vehicle

This off road guide is for vehicles that have four wheel drive.

Also, see “Anti Lock Brakes” in the Index.

If your vehicle doesn’t have four wheel drive, you shouldn’t drive off road unless you’re on a level, solid surface.

Off road driving can be great fun. But it does have some definite hazards. The greatest of these is the terrain itself.

“Off roading” means you’ve left the great North

American road system behind. Traffic lanes aren’t marked. Curves aren’t banked. There are no road signs.

Surfaces can be slippery, rough, uphill or downhill.

In short, you’ve gone right back to nature.

Off road driving involves some new skills. And that’s why it’s very important that you read this guide. You’ll find many driving tips and suggestions. These will help make your off road driving safer and more enjoyable.

If you think you will need some more ground clearance at the front of your vehicle, you can easily remove the front bumper lower air dam.

The front bumper lower air dam is held in place by a series of push pins located around the lower edge of the front bumper. The push pins are accessible from underneath the front bumper.

4-18

The following steps must be performed on each of the push pins to remove the air dam:

1. Insert a tool into the push pin slot and pull downward until the push pin snaps loose.

2. While continuing to pull downward on the push pin, squeeze and turn the expandable end of the push pin with a tool until it releases from the retainer.

4-19

3. Pull the push pins and lower air dam assembly away from the retainers until the lower air dam is free.

To reinstall the lower air dam do the following:

1. Line up each push pin with its intended retainer and push the washer portion of the push pin towards the retainer until it locks into place.

When you’re back on roads, though, be sure to replace the air dam.

NOTICE:

Operating your vehicle for extended periods without the front bumper lower air dam installed can cause improper air flow to the engine and may allow things like fog lamps or tow hooks on the front of your vehicle to be damaged. Always be sure to replace the front bumper air dam when you’re finished off road driving.

4-20

2. Push the flat end of the push pin towards the retainer until it locks into place, making sure each is secure.

Before You Go Off-Roading

There are some things to do before you go out.

For example, be sure to have all necessary maintenance and service work done. Check to make sure all underbody shields (if so equipped) are properly attached. Be sure you read all the information about your four wheel drive vehicle in this manual. Is there enough fuel? Is the spare tire fully inflated? Are the fluid levels up where they should be? What are the local laws that apply to off roading where you’ll be driving?

If you don’t know, you should check with law enforcement people in the area. Will you be on someone’s private land? If so, be sure to get the necessary permission.

Loading Your Vehicle for Off-Road Driving

There are some important things to remember about how to load your vehicle.

D The heaviest things should be on the load floor and forward of your rear axle. Put heavier items as far forward as you can.

D Be sure the load is secured properly, so driving on the off road terrain doesn’t toss things around.

CAUTION:

D Cargo on the load floor piled higher than the seatbacks can be thrown forward during a sudden stop. You or your passengers could be injured. Keep cargo below the top of the seatbacks.

D Unsecured cargo on the load floor can be tossed about when driving over rough terrain. You or your passengers can be struck by flying objects. Secure the cargo properly.

D Heavy loads on the roof raise the vehicle’s center of gravity, making it more likely to roll over. You can be seriously or fatally injured if the vehicle rolls over. Put heavy loads inside the cargo area, not on the roof.

Keep cargo in the cargo area as far forward and low as possible.

You’ll find other important information in this manual.

See “Vehicle Loading,” “Luggage Carrier” and “Tires” in the Index.

4-21

Environmental Concerns

Off road driving can provide wholesome and satisfying recreation. However, it also raises environmental concerns. GM recognizes these concerns and urges every off roader to follow these basic rules for protecting the environment:

D Always use established trails, roads and areas that have been specially set aside for public off road recreational driving; obey all posted regulations.

D Avoid any driving practice that could damage the environment - shrubs, flowers, trees, grasses - or disturb wildlife (this includes wheel spinning, breaking down trees or unnecessary driving through streams or over soft ground).

D Always carry a litter bag . . . make sure all refuse is removed from any campsite before leaving.

D Take extreme care with open fires (where permitted), camp stoves and lanterns.

D Never park your vehicle over dry grass or other combustible materials that could catch fire from the heat of the vehicle’s exhaust system.

Traveling to Remote Areas

It makes sense to plan your trip, especially when going to a remote area. Know the terrain and plan your route.

You are much less likely to get bad surprises. Get accurate maps of trails and terrain. Try to learn of any blocked or closed roads.

It’s also a good idea to travel with at least one other vehicle. If something happens to one of them, the other can help quickly.

Does your vehicle have a winch? If so, be sure to read the winch instructions. In a remote area, a winch can be handy if you get stuck. But you’ll want to know how to use it properly.

4-22

Getting Familiar with Off-Road Driving

It’s a good idea to practice in an area that’s safe and close to home before you go into the wilderness.

Off road driving does require some new and different driving skills. Here’s what we mean.

Tune your senses to different kinds of signals. Your eyes, for example, need to constantly sweep the terrain for unexpected obstacles. Your ears need to listen for unusual tire or engine sounds. With your arms, hands, feet and body, you’ll need to respond to vibrations and vehicle bounce.

Controlling your vehicle is the key to successful off road driving. One of the best ways to control your vehicle is to control your speed. Here are some things to keep in mind. At higher speeds:

D you approach things faster and you have less time to scan the terrain for obstacles.

D you have less time to react.

D you have more vehicle bounce when you drive over obstacles.

D you’ll need more distance for braking, especially since you’re on an unpaved surface.

CAUTION:

When you’re driving off road, bouncing and quick changes in direction can easily throw you out of position. This could cause you to lose control and crash. So, whether you’re driving on or off the road, you and your passengers should wear safety belts.

4-23

Scanning the Terrain

Off road driving can take you over many different kinds of terrain. You need to be familiar with the terrain and its many different features. Here are some things to consider.

Surface Conditions. Off roading can take you over hard packed dirt, gravel, rocks, grass, sand, mud, snow or ice. Each of these surfaces affects the steering, acceleration and braking of your vehicle in different ways. Depending upon the kind of surface you are on, you may experience slipping, sliding, wheel spinning, delayed acceleration, poor traction and longer braking distances.

Surface Obstacles. Unseen or hidden obstacles can be hazardous. A rock, log, hole, rut or bump can startle you if you’re not prepared for them. Often these obstacles are hidden by grass, bushes, snow or even the rise and fall of the terrain itself. Here are some things to consider:

D Is the path ahead clear?

D Will the surface texture change abruptly up ahead?

D Does the travel take you uphill or downhill? (There’s more discussion of these subjects later.)

D Will you have to stop suddenly or change direction quickly?

When you drive over obstacles or rough terrain, keep a firm grip on the steering wheel. Ruts, troughs or other surface features can jerk the wheel out of your hands if you’re not prepared.

When you drive over bumps, rocks, or other obstacles, your wheels can leave the ground. If this happens, even with one or two wheels, you can’t control the vehicle as well or at all.

Because you will be on an unpaved surface, it’s especially important to avoid sudden acceleration, sudden turns or sudden braking.

In a way, off road driving requires a different kind of alertness from driving on paved roads and highways.

There are no road signs, posted speed limits or signal lights. You have to use your own good judgment about what is safe and what isn’t.

Drinking and driving can be very dangerous on any road. And this is certainly true for off road driving.

At the very time you need special alertness and driving skills, your reflexes, perceptions and judgment can be affected by even a small amount of alcohol. You could have a serious - or even fatal - accident if you drink and drive or ride with a driver who has been drinking.

See “Drunken Driving” in the Index.

4-24

Driving on Off-Road Hills

Off road driving often takes you up, down or across a hill. Driving safely on hills requires good judgment and an understanding of what your vehicle can and can’t do.

There are some hills that simply can’t be driven, no matter how well built the vehicle.

CAUTION:

Many hills are simply too steep for any vehicle. If you drive up them, you will stall. If you drive down them, you can’t control your speed. If you drive across them, you will roll over. You could be seriously injured or killed. If you have any doubt about the steepness, don’t drive the hill.

Approaching a Hill

When you approach a hill, you need to decide if it’s one of those hills that’s just too steep to climb, descend or cross. Steepness can be hard to judge. On a very small hill, for example, there may be a smooth, constant incline with only a small change in elevation where you can easily see all the way to the top. On a large hill, the incline may get steeper as you near the top, but you may not see this because the crest of the hill is hidden by bushes, grass or shrubs.

Here are some other things to consider as you approach a hill.

D Is there a constant incline, or does the hill get sharply steeper in places?

D Is there good traction on the hillside, or will the surface cause tire slipping?

D Is there a straight path up or down the hill so you won’t have to make turning maneuvers?

D Are there obstructions on the hill that can block your path (boulders, trees, logs or ruts)?

D What’s beyond the hill? Is there a cliff, an embankment, a drop off, a fence? Get out and walk the hill if you don’t know. It’s the smart way to find out.

D Is the hill simply too rough? Steep hills often have ruts, gullies, troughs and exposed rocks because they are more susceptible to the effects of erosion.

4-25

Driving Uphill

Once you decide you can safely drive up the hill, you need to take some special steps.

D Use a low gear and get a firm grip on the steering wheel.

D Get a smooth start up the hill and try to maintain your speed. Don’t use more power than you need, because you don’t want your wheels to start spinning or sliding.

D Try to drive straight up the hill if at all possible.

If the path twists and turns, you might want to find another route.

CAUTION:

Turning or driving across steep hills can be dangerous. You could lose traction, slide sideways, and possibly roll over. You could be seriously injured or killed. When driving up hills, always try to go straight up.

D Ease up on your speed as you approach the top of the hill.

D Attach a flag to the vehicle to make you more visible to approaching traffic on trails or hills.

D Sound the horn as you approach the top of the hill to let opposing traffic know you’re there.

D Use your headlamps even during the day. They make you more visible to oncoming traffic.

CAUTION:

Driving to the top (crest) of a hill at full speed can cause an accident. There could be a drop off, embankment, cliff, or even another vehicle. You could be seriously injured or killed. As you near the top of a hill, slow down and stay alert.

4-26

Q:

What should I do if my vehicle stalls, or is about to stall, and I can’t make it up the hill?

A:

If this happens, there are some things you should do, and there are some things you must not do.

First, here’s what you should do:

D Push the brake pedal to stop the vehicle and keep it from rolling backwards. Also, apply the parking brake.

D If your engine is still running, shift the transmission to REVERSE (R), release the parking brake, and slowly back down the hill in REVERSE (R).

D If your engine has stopped running, you’ll need to restart it. With the brake pedal pressed and the parking brake still applied, shift the transmission to

PARK (P) and restart the engine. Then, shift to

REVERSE (R), release the parking brake, and slowly back down the hill as straight as possible in REVERSE (R).

D As you are backing down the hill, put your left hand on the steering wheel at the 12 o’clock position. This way, you’ll be able to tell if your wheels are straight and maneuver as you back down. It’s best that you back down the hill with your wheels straight rather than in the left or right direction. Turning the wheel too far to the left or right will increase the possibility of a rollover.

Here are some things you must not do if you stall, or are about to stall, when going up a hill.

D Never attempt to prevent a stall by shifting into

NEUTRAL (N) to “rev up” the engine and regain forward momentum. This won’t work. Your vehicle will roll backwards very quickly and you could go out of control.

Instead, apply the regular brake to stop the vehicle. Then apply the parking brake. Shift to

REVERSE (R), release the parking brake, and slowly back straight down.

D Never attempt to turn around if you are about to stall when going up a hill. If the hill is steep enough to stall your vehicle, it’s steep enough to cause you to roll over if you turn around. If you can’t make it up the hill, you must back straight down the hill.

4-27

Q:

Suppose, after stalling, I try to back down the hill and decide I just can’t do it. What should I do?

A:

Set the parking brake, put your transmission in

PARK (P) and turn off the engine. Leave the vehicle and go get some help. Exit on the uphill side and stay clear of the path the vehicle would take if it rolled downhill. Do not shift the transfer case to NEUTRAL when you leave the vehicle.

Leave it in some gear.

CAUTION:

Shifting the transfer case to NEUTRAL can cause your vehicle to roll even if the transmission is in PARK (P). This is because the NEUTRAL position on the transfer case overrides the transmission. You or someone else could be injured. If you are going to leave your vehicle, set the parking brake and shift the transmission to PARK (P). But do not shift the transfer case to NEUTRAL. Leave the transfer case in the

2 Wheel High, 4 High or 4 Low position.

4-28

Driving Downhill

When off roading takes you downhill, you’ll want to consider a number of things:

D How steep is the downhill? Will I be able to maintain vehicle control?

D What’s the surface like? Smooth? Rough? Slippery?

Hard packed dirt? Gravel?

D Are there hidden surface obstacles? Ruts?

Logs? Boulders?

D What’s at the bottom of the hill? Is there a hidden creek bank or even a river bottom with large rocks?

If you decide you can go down a hill safely, then try to keep your vehicle headed straight down, and use a low gear. This way, engine drag can help your brakes and they won’t have to do all the work. Descend slowly, keeping your vehicle under control at all times.

CAUTION:

Heavy braking when going down a hill can cause your brakes to overheat and fade. This could cause loss of control and a serious accident.

Apply the brakes lightly when descending a hill and use a low gear to keep vehicle speed under control.

4-29

Q:

Are there some things I should not do when driving down a hill?

A:

Yes! These are important because if you ignore them you could lose control and have a serious accident.

D When driving downhill, avoid turns that take you across the incline of the hill. A hill that’s not too steep to drive down may be too steep to drive across.

You could roll over if you don’t drive straight down.

D Never go downhill with the transmission in

NEUTRAL (N). This is called “free wheeling.”

Your brakes will have to do all the work and could overheat and fade.

Q:

Am I likely to stall when going downhill?

A:

It’s much more likely to happen going uphill. But if it happens going downhill, here’s what to do.

D Stop your vehicle by applying the regular brakes.

Apply the parking brake.

D Shift to PARK (P) and, while still braking, restart the engine.

D Shift back to a low gear, release the parking brake, and drive straight down.

D If the engine won’t start, get out and get help.

4-30

Driving Across an Incline

Sooner or later, an off road trail will probably go across the incline of a hill. If this happens, you have to decide whether to try to drive across the incline. Here are some things to consider:

D A hill that can be driven straight up or down may be too steep to drive across. When you go straight up or down a hill, the length of the wheel base (the distance from the front wheels to the rear wheels) reduces the likelihood the vehicle will tumble end over end. But when you drive across an incline, the much more narrow track width (the distance between the left and right wheels) may not prevent the vehicle from tilting and rolling over. Also, driving across an incline puts more weight on the downhill wheels.

This could cause a downhill slide or a rollover.

D Surface conditions can be a problem when you drive across a hill. Loose gravel, muddy spots, or even wet grass can cause your tires to slip sideways, downhill.

If the vehicle slips sideways, it can hit something that will trip it (a rock, a rut, etc.) and roll over.

D Hidden obstacles can make the steepness of the incline even worse. If you drive across a rock with the uphill wheels, or if the downhill wheels drop into a rut or depression, your vehicle can tilt even more.

For reasons like these, you need to decide carefully whether to try to drive across an incline. Just because the trail goes across the incline doesn’t mean you have to drive it. The last vehicle to try it might have rolled over.

CAUTION:

Driving across an incline that’s too steep will make your vehicle roll over. You could be seriously injured or killed. If you have any doubt about the steepness of the incline, don’t drive across it. Find another route instead.

4-31

Q:

What if I’m driving across an incline that’s not too steep, but I hit some loose gravel and start to slide downhill. What should I do?

A:

If you feel your vehicle starting to slide sideways, turn downhill. This should help straighten out the vehicle and prevent the side slipping. However, a much better way to prevent this is to get out and

“walk the course” so you know what the surface is like before you drive it.

Stalling on an Incline

If your vehicle stalls when you’re crossing an incline, be sure you (and your passengers) get out on the uphill side, even if the door there is harder to open. If you get out on the downhill side and the vehicle starts to roll over, you’ll be right in its path.

If you have to walk down the slope, stay out of the path the vehicle will take if it does roll over.

CAUTION:

Getting out on the downhill (low) side of a vehicle stopped across an incline is dangerous. If the vehicle rolls over, you could be crushed or killed.

Always get out on the uphill (high) side of the vehicle and stay well clear of the rollover path.

4-32

Driving in Mud, Sand, Snow or Ice

When you drive in mud, snow or sand, your wheels won’t get good traction. You can’t accelerate as quickly, turning is more difficult, and you’ll need longer braking distances.

It’s best to use a low gear when you’re in mud - the deeper the mud, the lower the gear. In really deep mud, the idea is to keep your vehicle moving so you don’t get stuck.

When you drive on sand, you’ll sense a change in wheel traction. But it will depend upon how loosely packed the sand is. On loosely packed sand (as on beaches or sand dunes) your tires will tend to sink into the sand. This has an effect on steering, accelerating and braking. You may want to reduce the air pressure in your tires slightly when driving on sand. This will improve traction.

Hard packed snow and ice offer the worst tire traction.

On these surfaces, it’s very easy to lose control. On wet ice, for example, the traction is so poor that you will have difficulty accelerating. And if you do get moving, poor steering and difficult braking can cause you to slide out of control.

CAUTION:

Driving on frozen lakes, ponds or rivers can be dangerous. Underwater springs, currents under the ice, or sudden thaws can weaken the ice. Your vehicle could fall through the ice and you and your passengers could drown. Drive your vehicle on safe surfaces only.

4-33

Driving in Water

Light rain causes no special off road driving problems.

But heavy rain can mean flash flooding, and flood waters demand extreme caution.

Find out how deep the water is before you drive through it. If it’s deep enough to cover your wheel hubs, axles or exhaust pipe, don’t try it - you probably won’t get through. Also, water that deep can damage your axle and other vehicle parts.

If the water isn’t too deep, then drive through it slowly.

At fast speeds, water splashes on your ignition system and your vehicle can stall. Stalling can also occur if you get your tailpipe under water. And, as long as your tailpipe is under water, you’ll never be able to start your engine. When you go through water, remember that when your brakes get wet, it may take you longer to stop.

CAUTION:

Driving through rushing water can be dangerous.

Deep water can sweep your vehicle downstream and you and your passengers could drown. If it’s only shallow water, it can still wash away the ground from under your tires, and you could lose traction and roll the vehicle over. Don’t drive through rushing water.

See “Driving Through Water” in the Index for more information on driving through water.

4-34

After Off-Road Driving

Remove any brush or debris that has collected on the underbody, chassis or under the hood. These accumulations can be a fire hazard.

After operation in mud or sand, have the brake linings cleaned and checked. These substances can cause glazing and uneven braking. Check the body structure, steering, suspension, wheels, tires and exhaust system for damage. Also, check the fuel lines and cooling system for any leakage.

Your vehicle will require more frequent service due to off road use. Refer to the Maintenance Schedule for additional information.

Driving at Night

Night driving is more dangerous than day driving.

One reason is that some drivers are likely to be impaired - by alcohol or drugs, with night vision problems, or by fatigue.

4-35

Here are some tips on night driving.

D Drive defensively.

D Don’t drink and drive.

D Adjust your inside rearview mirror to reduce the glare from headlamps behind you.

D Since you can’t see as well, you may need to slow down and keep more space between you and other vehicles.

D Slow down, especially on higher speed roads. Your headlamps can light up only so much road ahead.

D In remote areas, watch for animals.

D If you’re tired, pull off the road in a safe place and rest.

No one can see as well at night as in the daytime. But as we get older these differences increase. A 50 year old driver may require at least twice as much light to see the same thing at night as a 20 year old.

What you do in the daytime can also affect your night vision. For example, if you spend the day in bright sunshine you are wise to wear sunglasses. Your eyes will have less trouble adjusting to night. But if you’re driving, don’t wear sunglasses at night. They may cut down on glare from headlamps, but they also make a lot of things invisible.

4-36

You can be temporarily blinded by approaching headlamps. It can take a second or two, or even several seconds, for your eyes to readjust to the dark. When you are faced with severe glare (as from a driver who doesn’t lower the high beams, or a vehicle with misaimed headlamps), slow down a little. Avoid staring directly into the approaching headlamps.

Keep your windshield and all the glass on your vehicle clean - inside and out. Glare at night is made much worse by dirt on the glass. Even the inside of the glass can build up a film caused by dust. Dirty glass makes lights dazzle and flash more than clean glass would, making the pupils of your eyes contract repeatedly.

Remember that your headlamps light up far less of a roadway when you are in a turn or curve. Keep your eyes moving; that way, it’s easier to pick out dimly lighted objects. Just as your headlamps should be checked regularly for proper aim, so should your eyes be examined regularly. Some drivers suffer from night blindness - the inability to see in dim light - and aren’t even aware of it.

Driving in Rain and on Wet Roads

Rain and wet roads can mean driving trouble. On a wet road, you can’t stop, accelerate or turn as well because your tire to road traction isn’t as good as on dry roads.

And, if your tires don’t have much tread left, you’ll get even less traction. It’s always wise to go slower and be cautious if rain starts to fall while you are driving. The surface may get wet suddenly when your reflexes are tuned for driving on dry pavement.

The heavier the rain, the harder it is to see. Even if your windshield wiper blades are in good shape, a heavy rain can make it harder to see road signs and traffic signals, pavement markings, the edge of the road and even people walking.

It’s wise to keep your wiping equipment in good shape and keep your windshield washer tank filled with washer fluid. Replace your windshield wiper inserts when they show signs of streaking or missing areas on the windshield, or when strips of rubber start to separate from the inserts.

4-37

Driving too fast through large water puddles or even going through some car washes can cause problems, too.

The water may affect your brakes. Try to avoid puddles.

But if you can’t, try to slow down before you hit them.

CAUTION:

Wet brakes can cause accidents. They won’t work as well in a quick stop and may cause pulling to one side. You could lose control of the vehicle.

After driving through a large puddle of water or a car wash, apply your brake pedal lightly until your brakes work normally.

Hydroplaning

Hydroplaning is dangerous. So much water can build up under your tires that they can actually ride on the water.

This can happen if the road is wet enough and you’re going fast enough. When your vehicle is hydroplaning, it has little or no contact with the road.

Hydroplaning doesn’t happen often. But it can if your tires do not have much tread or if the pressure in one or more is low. It can happen if a lot of water is standing on the road. If you can see reflections from trees, telephone poles or other vehicles, and raindrops “dimple” the water’s surface, there could be hydroplaning.

Hydroplaning usually happens at higher speeds. There just isn’t a hard and fast rule about hydroplaning. The best advice is to slow down when it is raining.

4-38

Driving Through Deep Standing Water

NOTICE:

If you drive too quickly through deep puddles or standing water, water can come in through your engine’s air intake and badly damage your engine. Never drive through water that is slightly lower than the underbody of your vehicle. If you can’t avoid deep puddles or standing water, drive through them very slowly.

Driving Through Flowing Water

CAUTION:

Flowing or rushing water creates strong forces.

If you try to drive through flowing water, as you might at a low water crossing, your vehicle can be carried away. As little as six inches of flowing water can carry away a smaller vehicle. If this happens, you and the other vehicle occupants could drown. Don’t ignore police warning signs, and otherwise be very cautious about trying to drive through flowing water.

Some Other Rainy Weather Tips

D Turn on your low parking lamps

beam headlamps - not just your

- to help make you more visible to others.

D Besides slowing down, allow some extra following distance. And be especially careful when you pass another vehicle. Allow yourself more clear room ahead, and be prepared to have your view restricted by road spray.

D Have good tires with proper tread depth. See “Tires” in the Index.

4-39

City Driving

One of the biggest problems with city streets is the amount of traffic on them. You’ll want to watch out for what the other drivers are doing and pay attention to traffic signals.

Here are ways to increase your safety in city driving:

D Know the best way to get to where you are going. Get a city map and plan your trip into an unknown part of the city just as you would for a cross country trip.

D Try to use the freeways that rim and crisscross most large cities. You’ll save time and energy. See the next part, “Freeway Driving.”

D Treat a green light as a warning signal. A traffic light is there because the corner is busy enough to need it. When a light turns green, and just before you start to move, check both ways for vehicles that have not cleared the intersection or may be running the red light.

4-40

Freeway Driving

Mile for mile, freeways (also called thruways, parkways, expressways, turnpikes or superhighways) are the safest of all roads. But they have their own special rules.

The most important advice on freeway driving is: Keep up with traffic and keep to the right. Drive at the same speed most of the other drivers are driving. Too fast or too slow driving breaks a smooth traffic flow. Treat the left lane on a freeway as a passing lane.

At the entrance, there is usually a ramp that leads to the freeway. If you have a clear view of the freeway as you drive along the entrance ramp, you should begin to check traffic. Try to determine where you expect to blend with the flow. Try to merge into the gap at close to the prevailing speed. Switch on your turn signal, check your mirrors and glance over your shoulder as often as necessary. Try to blend smoothly with the traffic flow.

Once you are on the freeway, adjust your speed to the posted limit or to the prevailing rate if it’s slower. Stay in the right lane unless you want to pass.

Before changing lanes, check your mirrors. Then use your turn signal.

Just before you leave the lane, glance quickly over your shoulder to make sure there isn’t another vehicle in your

“blind” spot.

Once you are moving on the freeway, make certain you allow a reasonable following distance. Expect to move slightly slower at night.

When you want to leave the freeway, move to the proper lane well in advance. If you miss your exit, do not, under any circumstances, stop and back up. Drive on to the next exit.

The exit ramp can be curved, sometimes quite sharply.

4-41

The exit speed is usually posted.

Reduce your speed according to your speedometer, not to your sense of motion. After driving for any distance at higher speeds, you may tend to think you are going slower than you actually are.

Before Leaving on a Long Trip

Make sure you’re ready. Try to be well rested. If you must start when you’re not fresh - such as after a day’s work - don’t plan to make too many miles that first part of the journey. Wear comfortable clothing and shoes you can easily drive in.

Is your vehicle ready for a long trip? If you keep it serviced and maintained, it’s ready to go. If it needs service, have it done before starting out. Of course, you’ll find experienced and able service experts in GM dealerships all across North America. They’ll be ready and willing to help if you need it.

Here are some things you can check before a trip:

D Windshield Washer Fluid: Is the reservoir full?

Are all windows clean inside and outside?

D Wiper Blades: Are they in good shape?

D Fuel, Engine Oil, Other Fluids: Have you checked all levels?

D Lamps: Are they all working? Are the lenses clean?

D Tires: They are vitally important to a safe, trouble free trip. Is the tread good enough for long distance driving? Are the tires all inflated to the recommended pressure?

D Weather Forecasts: What’s the weather outlook along your route? Should you delay your trip a short time to avoid a major storm system?

D Maps: Do you have up to date maps?

4-42

Highway Hypnosis

Is there actually such a condition as “highway hypnosis”? Or is it just plain falling asleep at the wheel? Call it highway hypnosis, lack of awareness, or whatever.

There is something about an easy stretch of road with the same scenery, along with the hum of the tires on the road, the drone of the engine, and the rush of the wind against the vehicle that can make you sleepy. Don’t let it happen to you! If it does, your vehicle can leave the road in less than a second, and you could crash and be injured.

What can you do about highway hypnosis? First, be aware that it can happen.

Then here are some tips:

D Make sure your vehicle is well ventilated, with a comfortably cool interior.

D Keep your eyes moving. Scan the road ahead and to the sides. Check your mirrors and your instruments frequently.

D If you get sleepy, pull off the road into a rest, service or parking area and take a nap, get some exercise, or both. For safety, treat drowsiness on the highway as an emergency.

Hill and Mountain Roads

Driving on steep hills or mountains is different from driving in flat or rolling terrain.

4-43

If you drive regularly in steep country, or if you’re planning to visit there, here are some tips that can make your trips safer and more enjoyable. See “Off Road

Driving” in the Index for information about driving off road.

D Keep your vehicle in good shape. Check all fluid levels and also the brakes, tires, cooling system and transmission. These parts can work hard on mountain roads.

D Know how to go down hills. The most important thing to know is this: let your engine do some of the slowing down. Shift to a lower gear when you go down a steep or long hill.

CAUTION:

If you don’t shift down, your brakes could get so hot that they wouldn’t work well. You would then have poor braking or even none going down a hill. You could crash. Shift down to let your engine assist your brakes on a steep downhill slope.

CAUTION:

Coasting downhill in NEUTRAL (N) or with the ignition off is dangerous. Your brakes will have to do all the work of slowing down. They could get so hot that they wouldn’t work well. You would then have poor braking or even none going down a hill.

You could crash. Always have your engine running and your vehicle in gear when you go downhill.

D Know how to go uphill. You may want to shift down to a lower gear. The lower gears help cool your engine and transmission, and you can climb the hill better.

D Stay in your own lane when driving on two lane roads in hills or mountains. Don’t swing wide or cut across the center of the road. Drive at speeds that let you stay in your own lane.

D As you go over the top of a hill, be alert. There could be something in your lane, like a stalled car or an accident.

D You may see highway signs on mountains that warn of special problems. Examples are long grades, passing or no passing zones, a falling rocks area or winding roads. Be alert to these and take appropriate action.

4-44

Winter Driving

Here are some tips for winter driving:

D Have your vehicle in good shape for winter.

D You may want to put winter emergency supplies in your vehicle.

Include an ice scraper, a small brush or broom, a supply of windshield washer fluid, a rag, some winter outer clothing, a small shovel, a flashlight, a red cloth and reflective warning triangles. And, if you will be driving under severe conditions, include a small bag of sand, a piece of old carpet or a couple of burlap bags to help provide traction. Be sure you properly secure these items in your vehicle.

4-45

Driving on Snow or Ice

Most of the time, those places where your tires meet the road probably have good traction.

However, if there is snow or ice between your tires and the road, you can have a very slippery situation. You’ll have a lot less traction or “grip” and will need to be very careful.

What’s the worst time for this? “Wet ice.” Very cold snow or ice can be slick and hard to drive on. But wet ice can be even more trouble because it may offer the least traction of all. You can get wet ice when it’s about freezing (32

_F; 0_C) and freezing rain begins to fall.

Try to avoid driving on wet ice until salt and sand crews can get there.

Whatever the condition - smooth ice, packed, blowing or loose snow - drive with caution.

Accelerate gently. Try not to break the fragile traction.

If you accelerate too fast, the drive wheels will spin and polish the surface under the tires even more.

If you have traction assist, keep the system on. It will improve your ability to accelerate when driving on a slippery road. But you can turn the traction system off if you ever need to. You should turn the system off if your vehicle ever gets stuck in sand, mud, ice or snow.

See “Rocking Your Vehicle” in the Index. Even though your vehicle has a traction system, you’ll want to slow down and adjust your driving to the road conditions.

See “Traction Assist System” in the Index.

4-46

If you don’t have a traction system, accelerate gently.

Try not to break the gentle traction. If you accelerate too fast, the drive wheels will spin and polish the surface under the tires even more.

Your anti lock brakes improve your vehicle’s stability when you make a hard stop on a slippery road. Even though you have an anti lock braking system, you’ll want to begin stopping sooner than you would on dry pavement. See “Anti Lock” in the Index.

D Allow greater following distance on any slippery road.

D Watch for slippery spots. The road might be fine until you hit a spot that’s covered with ice. On an otherwise clear road, ice patches may appear in shaded areas where the sun can’t reach: around clumps of trees, behind buildings or under bridges.

Sometimes the surface of a curve or an overpass may remain icy when the surrounding roads are clear. If you see a patch of ice ahead of you, brake before you are on it. Try not to brake while you’re actually on the ice, and avoid sudden steering maneuvers.

If You’re Caught in a Blizzard

If you are stopped by heavy snow, you could be in a serious situation. You should probably stay with your vehicle unless you know for sure that you are near help and you can hike through the snow. Here are some things to do to summon help and keep yourself and your passengers safe:

D Turn on your hazard flashers.

4-47

D Tie a red cloth to your vehicle to alert police that you’ve been stopped by the snow.

D Put on extra clothing or wrap a blanket around you.

If you have no blankets or extra clothing, make body insulators from newspapers, burlap bags, rags, floor mats - anything you can wrap around yourself or tuck under your clothing to keep warm.

CAUTION:

Snow can trap exhaust gases under your vehicle.

This can cause deadly CO (carbon monoxide) gas to get inside. CO could overcome you and kill you. You can’t see it or smell it, so you might not know it is in your vehicle. Clear away snow from around the base of your vehicle, especially any that is blocking your exhaust pipe. And check around again from time to time to be sure snow doesn’t collect there.

Open a window just a little on the side of the vehicle that’s away from the wind. This will help keep CO out.

Run your engine only as long as you must. This saves fuel. When you run the engine, make it go a little faster than just idle. That is, push the accelerator slightly. This uses less fuel for the heat that you get and it keeps the battery charged. You will need a well charged battery to restart the vehicle, and possibly for signaling later on with your headlamps. Let the heater run for a while.

You can run the engine to keep warm, but be careful.

4-48

Then, shut the engine off and close the window almost all the way to preserve the heat. Start the engine again and repeat this only when you feel really uncomfortable from the cold. But do it as little as possible. Preserve the fuel as long as you can. To help keep warm, you can get out of the vehicle and do some fairly vigorous exercises every half hour or so until help comes.

Recreational Vehicle Towing

Recreational vehicle towing means towing your vehicle behind another vehicle - such as behind a motorhome. The two most common types of recreational vehicle towing are known as “dinghy towing” (towing your vehicle with all four wheels on the ground) and “dolly towing” (towing your vehicle with two wheels on the ground and two wheels up on a device known as a “dolly”).

With the proper preparation and equipment, many vehicles can be towed in these ways. See “Dinghy

Towing” and “Dolly Towing,” following.

Here are some important things to consider before you do recreational vehicle towing:

D What’s the towing capacity of the towing vehicle? Be sure you read the tow vehicle manufacturer’s recommendations.

D How far will you tow? Some vehicles have restrictions on how far and how long they can tow.

D Do you have the proper towing equipment? See your dealer or trailering professional for additional advice and equipment recommendations.

D Is your vehicle ready to be towed? Just as you would prepare your vehicle for a long trip, you’ll want to make sure your vehicle is prepared to be towed. See “Before Leaving on a Long Trip” in the Index.

4-49

Dinghy Towing

When towing your vehicle, turn the ignition off.

To prevent your battery from draining while towing, remove the IGN 0 fuse from the instrument panel fuse block. Be sure to reinstall the fuse when you reach your destination. See “Fuses and Circuit Breakers” in the Index.

Two Wheel Drive Vehicles

Two wheel drive vehicles, should not be towed with all four wheels on the ground. Two wheel drive transmissions have no provisions for internal lubrication while being towed. To properly tow these vehicles, they should be placed on a platform trailer with all four wheels off the ground.

In rare cases when it’s unavoidable that a two wheel drive vehicle is to be towed with all four wheels on the ground, the propeller shaft to axle yoke orientation should be marked and the propeller shaft removed following the applicable service manual removal/installation procedure.

Dust or dirt can enter the back of the transmission through the opening created by removing the propeller shaft if proper protection is not provided. Also, check the transmission fluid level before driving the truck.

4-50

Four Wheel Drive Vehicles

Use the following procedure to tow your vehicle:

1. Firmly set the parking brake.

2. Shift an automatic transmission to PARK (P), or a manual transmission to FIRST (1).

3. Securely attach the vehicle being towed to the tow vehicle.

4. Shift the transfer case to NEUTRAL. See

“Four Wheel Drive” in the Index for the proper procedure to select the NEUTRAL position for your vehicle.

5. Release the parking brake only after the vehicle being towed is firmly attached to the towing vehicle.

6. Turn the ignition off.

CAUTION:

Shifting a four wheel drive vehicle’s transfer case into NEUTRAL can cause your vehicle to roll even if the transmission is in Park (P). You or others could be injured. Make sure the parking brake is firmly set before you shift the transfer case to NEUTRAL.

4-51

Dolly Towing (Two-Wheel Drive Vehicles)

Two–Wheel–Drive Vehicles

Two–wheel–drive, vehicles,should not be towed with the rear wheels on the ground. Two–wheel–drive transmissions have no provisions for internal lubrication while being towed. To properly tow these vehicles, they should be placed on a platform trailer with all four wheels off the ground.

In rare cases when it’s unavoidable that a two–wheel drive vehicle is to be towed with the rear wheels on the ground, the propeller shaft axle yoke orientation should be marked and the propeller shaft removed following the application service manual removal/installation procedure.

Dust or dirt can enter the back of the transmission through the opening created by removing the propeller shaft if proper protection is not provided. Also, check the transmission fluid level before driving the truck.

When the vehicle is properly attached to the tow vehicle and is ready to be towed,turn the ignition to LOCK.

Clamp the steering wheel in a straight–ahead position with a clamping device designed for towing.

Four–Wheel–Drive Vehicles

Four–wheel drive vehicles are not designed to be dolly towed.

If you need to tow a four–wheel drive vehicle see

“Dinghy Towing” earlier in this section.

NOTICE:

Dolly towing a four wheel drive vehicle will damage drivetrain components. Don’t dolly tow a four wheel drive vehicle.

4-52

Loading Your Vehicle

The Certification/Tire label is found on the rear edge of the driver’s door or in the Incomplete Vehicle Document in the cab.

The label shows the size of your original tires and the inflation pressures needed to obtain the gross weight capacity of your vehicle. This is called the GVWR

(Gross Vehicle Weight Rating). The GVWR includes the weight of the vehicle, all occupants, fuel and cargo.

The Certification/Tire label also tells you the maximum weights for the front and rear axles, called Gross Axle

Weight Rating (GAWR). To find out the actual loads on your front and rear axles, you need to go to a weigh station and weigh your vehicle. Your dealer can help you with this. Be sure to spread out your load equally on both sides of the centerline.

Never exceed the GVWR for your vehicle, or the

GAWR for either the front or rear axle.

The Certification/Tire label also contains information about your Front Axle Reserve Capacity. See “Front

Axle Reserve Capacity” later in this section.

And, if you do have a heavy load, you should spread it out.

4-53

CAUTION:

Do not load your vehicle any heavier than the

GVWR, or either the maximum front or rear

GAWR. If you do, parts on your vehicle can break, and it can change the way your vehicle handles. These could cause you to lose control and crash. Also, overloading can shorten the life of your vehicle.

NOTICE:

Your warranty does not cover parts or components that fail because of overloading.

The label will help you decide how much cargo and installed equipment your truck can carry.

Using heavier suspension components to get added durability might not change your weight ratings. Ask your dealer to help you load your vehicle the right way.

4-54

If you put things inside your vehicle - like suitcases, tools, packages, or anything else - they go as fast as the vehicle goes. If you have to stop or turn quickly, or if there is a crash, they’ll keep going.

CAUTION:

Things you put inside your vehicle can strike and injure people in a sudden stop or turn, or in a crash.

D Put things in the cargo area of your vehicle.

Try to spread the weight evenly.

D Never stack heavier things, like suitcases, inside the vehicle so that some of them are above the tops of the seats.

D Don’t leave an unsecured child restraint in your vehicle.

D When you carry something inside the vehicle, secure it whenever you can.

D Don’t leave a seat folded down unless you need to.

There’s also important loading information for off road driving in this manual. See “Loading Your Vehicle for

Off Road Driving” in the Index.

Trailer Recommendations

You must subtract your hitch loads from the Cargo

Weight Rating (CWR) for your vehicle. CWR is the maximum weight of the load your vehicle can carry.

It doesn’t included the weight of the people inside.

But you can figure about 150 lbs. (68 kg) for each seat.

The total cargo load must not be more than your vehicle’s CWR.

Weigh your vehicle with the trailer attached, so that you won’t go over the GVWR or GAWR. If you are using a weight distributing hitch, weigh the vehicle without the equalizer bars in place.

You’ll get the best performance if you spread out the weight of your load the right way, and if you choose the correct hitch and trailer brakes.

For more information, see “Trailer Towing” in the Index.

Towing a Trailer

CAUTION:

If you don’t use the correct equipment and drive properly, you can lose control when you pull a trailer. For example, if the trailer is too heavy, the brakes may not work well - or even at all. You and your passengers could be seriously injured. Pull a trailer only if you have followed all the steps in this section. Ask your dealer for advice and information about towing a trailer with your vehicle.

4-55

NOTICE:

Pulling a trailer improperly can damage your vehicle and result in costly repairs not covered by your warranty. To pull a trailer correctly, follow the advice in this part, and see your dealer for important information about towing a trailer with your vehicle. Additional rear axle maintenance is required for a vehicle used to tow a trailer. See

“Scheduled Maintenance Services” in the Index.

To identify what the vehicle trailering capacity is for your vehicle, you should read the information in

“Weight of the Trailer” that appears later in this section.

If yours was built with trailering options, as many are, it’s ready for heavier trailers. But trailering is different than just driving your vehicle by itself. Trailering means changes in handling, durability and fuel economy.

Successful, safe trailering takes correct equipment, and it has to be used properly.

That’s the reason for this part. In it are many time tested, important trailering tips and safety rules.

Many of these are important for your safety and that of your passengers. So please read this section carefully before you pull a trailer.

4-56

If You Do Decide To Pull A Trailer

If you do, here are some important points:

D There are many different laws, including speed limit restrictions, having to do with trailering. Make sure your rig will be legal, not only where you live but also where you’ll be driving. A good source for this information can be state or provincial police.

D Consider using a sway control if your trailer will weigh less than 5,000 lbs. (2 270 kg). You should always use a sway control if your trailer will weigh more than 5,000 lbs. (2 270 kg). You can ask a hitch dealer about sway controls.

D Don’t tow a trailer at all during the first 500 miles

(800 km) your new vehicle is driven. Your engine, axle or other parts could be damaged.

D Then, during the first 500 miles (800 km) that you tow a trailer, don’t drive over 50 mph (80 km/h) and don’t make starts at full throttle. This helps your engine and other parts of your vehicle wear in at the heavier loads.

D You can tow in DRIVE (D). You may want to shift the transmission to THIRD (3) or, if necessary, a lower gear selection if the transmission shifts too often (e.g., under heavy loads and/or hilly conditions). If you have a manual transmission and you are towing a trailer, it’s better not to use the highest gear. See “Tow/Haul Mode” in the Index.

Three important considerations have to do with weight:

D the weight of the trailer,

D the weight of the trailer tongue

D and the weight on your vehicle’s tires.

Tow/Haul Mode

Tow/haul is a feature that assists when pulling a heavy trailer or a large or heavy load. The purpose of the tow/haul mode is to:

D Reduce the frequency and improve the predictability of transmission shifts when pulling a heavy trailer or a large or heavy load.

D Provide the same solid shift feel when pulling a heavy trailer or a large or heavy load as when the vehicle is unloaded.

D Improve control of vehicle speed while requiring less throttle pedal activity when pulling a heavy trailer or a large or heavy load.

Your vehicle is equipped with a button at the end of the shift lever which, when pressed, enables tow/haul. Your vehicle may be equipped with Autoride

R

which further improves your vehicle’s ride while towing. See “Autoride

R

” in the

Index for more information. When the button is pressed, a light on the instrument panel will illuminate to indicate that tow/haul has been selected. Tow/haul may be turned off by pressing the button again, at which time the indicator light on the instrument panel will turn off. The vehicle will automatically turn off tow/haul every time it is started.

Tow/haul is designed to be most effective when the vehicle and trailer combined weight is at least

75% of the vehicle’s Gross Combined Weight Rating

(GCWR). See “Weight of the Trailer” later in this section. Tow/haul is most useful under the following driving conditions:

D When pulling a heavy trailer or a large or heavy load through rolling terrain.

D When pulling a heavy trailer or a large or heavy load in stop and go traffic.

D When pulling a heavy trailer or a large or heavy load in busy parking lots where improved low speed control of the vehicle is desired.

4-57

Operating the vehicle in tow/haul when lightly loaded or with no trailer at all will not cause damage. However, there is no benefit to the selection of tow/haul when the vehicle is unloaded. Such a selection when unloaded may result in unpleasant engine and transmission driving characteristics and reduced fuel economy. Tow/haul is recommended only when pulling a heavy trailer or a large or heavy load.

Weight of the Trailer

How heavy can a trailer safely be?

It depends on how you plan to use your rig. For example, speed, altitude, road grades, outside temperature and how much your vehicle is used to pull a trailer are all important. And, it can also depend on any special equipment that you have on your vehicle.

Use one of the following charts to determine how much your vehicle can weigh, based upon your vehicle model and options.

Maximum trailer weight is calculated assuming only the driver is in the tow vehicle and it has all the required trailering equipment. The weight of additional optional equipment, passengers and cargo in the tow vehicle must be subtracted from the maximum trailer weight.

The Gross Combination Weight Rating (GCWR) is the total allowable weight of the completely loaded vehicle and trailer including any passengers, cargo, equipment and conversions. The GCWR for your vehicle should not be exceeded.

Weight of the Trailer Tongue

The tongue load (A) of any trailer is an important weight to measure because it affects the total or gross weight of your vehicle. The Gross Vehicle Weight

(GVW) includes the curb weight of the vehicle, any cargo you may carry in it, and the people who will be riding in the vehicle. And if you will tow a trailer, you must add the tongue load to the GVW because your vehicle will be carrying that weight, too. See “Loading

Your Vehicle” in the Index for more information about your vehicle’s maximum load capacity.

If you’re using a weight carrying or a weight distributing hitch, the trailer tongue weight (A) should be 10 percent to 15 percent of the total loaded trailer weight (B). Do not exceed the maximum allowable tongue weight for your vehicle.

After you’ve loaded your trailer, weigh the trailer and then the tongue, separately, to see if the weights are proper. If they aren’t, you may be able to get them right simply by moving some items around in the trailer.

4-62

Total Weight on Your Vehicle’s Tires

Be sure your vehicle’s tires are inflated to the upper limit for cold tires. You’ll find these numbers on the

Certification label at the rear edge of the driver’s door or see “Tire Loading” in the Index. Then be sure you don’t go over the GVW limit for your vehicle, including the weight of the trailer tongue.

Hitches

It’s important to have the correct hitch equipment.

Crosswinds, large trucks going by and rough roads are a few reasons why you’ll need the right hitch. Here are some rules to follow:

D If you use a step bumper hitch, your bumper could be damaged in sharp turns. Make sure you have ample room when turning to avoid contact between the trailer and the bumper.

D If you’ll be pulling a trailer that, when loaded, will weigh more than 5,000 lbs (2 270 kg) be sure to use a properly mounted, weight distributing hitch and sway control of the proper size. This equipment is very important for proper vehicle loading and good handling when you’re driving.

D Will you have to make any holes in the body of your vehicle when you install a trailer hitch?

If you do, then be sure to seal the holes later when you remove the hitch. If you don’t seal them, deadly carbon monoxide (CO) from your exhaust can get into your vehicle. See “Carbon Monoxide” in the

Index. Dirt and water can, too.

Safety Chains

You should always attach chains between your vehicle and your trailer. Cross the safety chains under the tongue of the trailer to help prevent the tongue from contacting the road if it becomes separated from the hitch.

Instructions about safety chains may be provided by the hitch manufacturer or by the trailer manufacturer. For trailers up to 5,000 lbs. (2 270 kg) you may attach the safety chains to the attaching points on the bumper. For heavier trailers, follow the trailer or hitch manufacturer’s recommendation for attaching safety chains. With a factory installed trailering package, for vehicles equipped to pull a trailer up to 12,000 lbs.

(5 448 kg), you may attach the safety chains to the attaching point on the hitch platform. Always leave just enough slack so you can turn with your rig. Never allow safety chains to drag on the ground.

4-63

Trailer Brakes

If your trailer weighs more than 2,000 lbs. (900 kg) loaded, then it needs its own brakes - and they must be adequate. Be sure to read and follow the instructions for the trailer brakes so you’ll be able to install, adjust and maintain them properly.

Your trailer brake system can tap into the vehicle’s hydraulic brake system only if:

D The trailer parts can withstand 3,000 psi

(20 650 kPa) of pressure.

D The trailer’s brake system will use less than

0.02 cubic inches (0.3 cc) of fluid from your vehicle’s master cylinder. Otherwise, both braking systems won’t work well. You could even lose your brakes.

If everything checks out this far, make the brake tap at the port on the master cylinder that sends the fluid to the rear brakes. But don’t use copper tubing for this. If you do, it will bend and finally break off. Use steel brake tubing.

Driving with a Trailer

CAUTION:

If you have a rear most window open and you pull a trailer with your vehicle, carbon monoxide

(CO) could come into your vehicle. You can’t see or smell CO. It can cause unconsciousness or death. See “Engine Exhaust” in the Index. To maximize your safety when towing a trailer:

D Have your exhaust system inspected for leaks, and make necessary repairs before starting on your trip.

D Keep the rear most windows closed.

D If exhaust does come into your vehicle through a window in the rear or another opening, drive with your front, main heating or cooling system on and with the fan on any speed. This will bring fresh, outside air into your vehicle. Do not use

MAX A/C because it only recirculates the air inside your vehicle. See “Comfort

Controls” in the Index.

4-64

Towing a trailer requires a certain amount of experience.

Before setting out for the open road, you’ll want to get to know your rig. Acquaint yourself with the feel of handling and braking with the added weight of the trailer. And always keep in mind that the vehicle you are driving is now a good deal longer and not nearly as responsive as your vehicle is by itself.

Before you start, check the trailer hitch and platform

(and attachments), safety chains, electrical connector, lamps, tires and mirror adjustment. If the trailer has electric brakes, start your vehicle and trailer moving and then apply the trailer brake controller by hand to be sure the brakes are working. This lets you check your electrical connection at the same time.

During your trip, check occasionally to be sure that the load is secure, and that the lamps and any trailer brakes are still working.

Following Distance

Stay at least twice as far behind the vehicle ahead as you would when driving your vehicle without a trailer. This can help you avoid situations that require heavy braking and sudden turns.

Passing

You’ll need more passing distance up ahead when you’re towing a trailer. And, because you’re a good deal longer, you’ll need to go much farther beyond the passed vehicle before you can return to your lane.

Backing Up

Hold the bottom of the steering wheel with one hand.

Then, to move the trailer to the left, just move that hand to the left. To move the trailer to the right, move your hand to the right. Always back up slowly and, if possible, have someone guide you.

4-65

Making Turns

NOTICE:

Making very sharp turns while trailering could cause the trailer to come in contact with the vehicle. Your vehicle could be damaged. Avoid making very sharp turns while trailering.

When you’re turning with a trailer, make wider turns than normal. Do this so your trailer won’t strike soft shoulders, curbs, road signs, trees or other objects. Avoid jerky or sudden maneuvers. Signal well in advance.

Turn Signals When Towing a Trailer

The arrows on your instrument panel will flash whenever you signal a turn or lane change. Properly hooked up, the trailer lamps will also flash, telling other drivers you’re about to turn, change lanes or stop.

When towing a trailer, the arrows on your instrument panel will flash for turns even if the bulbs on the trailer are burned out. Thus, you may think drivers behind you are seeing your signal when they are not. It’s important to check occasionally to be sure the trailer bulbs are still working.

Driving On Grades

Reduce speed and shift to a lower gear before you start down a long or steep downgrade. If you don’t shift down, you might have to use your brakes so much that they would get hot and no longer work well.

You can tow in DRIVE (D). You may want to shift the transmission to THIRD (3) or, if necessary, a lower gear selection if the transmission shifts too often (e.g., under heavy loads and/or hilly conditions).

4-66

You may also want to activate the tow/haul mode if the transmission shifts too often. See “Tow/Haul Mode” in the Index.

When towing at high altitude on steep uphill grades, consider the following: Engine coolant will boil at a lower temperature than at normal altitudes. If you turn your engine off immediately after towing at high altitude on steep uphill grades, your vehicle may show signs similar to engine overheating. To avoid this, let the engine run while parked (preferably on level ground) with the automatic transmission in PARK (P) for a few minutes before turning the engine off. If you do get the overheat warning, see “Engine Overheating” in the Index.

Parking on Hills

CAUTION:

You really should not park your vehicle, with a trailer attached, on a hill. If something goes wrong, your rig could start to move. People can be injured, and both your vehicle and the trailer can be damaged.

But if you ever have to park your rig on a hill, here’s how to do it:

1. Apply your regular brake, but don’t shift into

PARK (P) yet.

2. Have someone place chocks under the trailer wheels.

3. When the wheel chocks are in place, release the regular brakes until the chocks absorb the load.

4. Reapply the regular brakes. Then apply your parking brake and shift into PARK (P).

4-67

5. If you have a four wheel drive vehicle, be sure the transfer case is in a drive gear and not in NEUTRAL.

6. Release the regular brakes.

CAUTION:

It can be dangerous to get out of your vehicle if the shift lever is not fully in PARK (P) with the parking brake firmly set. Your vehicle can roll.

If you have left the engine running, the vehicle can move suddenly. You or others could be injured. To be sure your vehicle won’t move, even when you’re on fairly level ground, use the steps that follow.

Always put the shift lever fully in PARK (P) with the parking brake firmly set.

If the transfer case on four wheel drive vehicles is in NEUTRAL, your vehicle will be free to roll, even if your shift lever is in PARK (P). So, be sure the transfer case is in a drive gear - not in NEUTRAL.

When You Are Ready to Leave After

Parking on a Hill

1. Apply your regular brakes and hold the pedal down while you:

D start your engine,

D shift into a gear, and

D release the parking brake.

2. Let up on the brake pedal.

3. Drive slowly until the trailer is clear of the chocks.

4. Stop and have someone pick up and store the chocks.

4-68

Maintenance When Trailer Towing

Your vehicle will need service more often when you’re pulling a trailer. See the Maintenance Schedule for more on this. Things that are especially important in trailer operation are automatic transmission fluid (don’t overfill), engine oil, axle lubricant, belt, cooling system and brake system. Each of these is covered in this manual, and the Index will help you find them quickly.

If you’re trailering, it’s a good idea to review these sections before you start your trip.

Check periodically to see that all hitch nuts and bolts are tight.

Hazard Warning Flashers

The hazard warning flasher is located at the top of the steering column.

Your hazard warning flashers let you warn others. They also let police know you have a problem. Your front and rear turn signal lamps will flash on and off.

Your hazard warning flashers work no matter what position your key is in, and even if the key isn’t in.

Press the button to make the front and rear turn signal lamps flash on and off. Press the button again to turn the flashers off.

When the hazard warning flashers are on, your turn signals won’t work.

Other Warning Devices

If you carry reflective triangles, you can use them to warn others. Set one up at the side of the road about

300 feet (100 m) behind your vehicle.

5-2

Jump Starting

If your battery (or batteries) has run down, you may want to use another vehicle and some jumper cables to start your vehicle. Be sure to follow the steps below to do it safely.

CAUTION:

Batteries can hurt you. They can be dangerous because:

D They contain acid that can burn you.

D They contain gas that can explode or ignite.

D They contain enough electricity to burn you.

If you don’t follow these steps exactly, some or all of these things can hurt you.

NOTICE:

Ignoring these steps could result in costly damage to your vehicle that wouldn’t be covered by your warranty.

The ACDelco

R

battery in your vehicle has a built in hydrometer. Do not charge, test or jump start the battery if the hydrometer looks clear or light yellow. Replace the battery when there is a clear or light yellow hydrometer and a cranking complaint.

Trying to start your vehicle by pushing or pulling it won’t work, and it could damage your vehicle.

1. Check the other vehicle. It must have a

12 volt battery with a negative ground system.

NOTICE:

If the other system isn’t a 12 volt system with a negative ground, both vehicles can be damaged.

5-3

2. Get the vehicles close enough so the jumper cables can reach, but be sure the vehicles aren’t touching each other. If they are, it could cause a ground connection you don’t want. You wouldn’t be able to start your vehicle, and the bad grounding could damage the electrical systems.

To avoid the possibility of the vehicles rolling, set the parking brake firmly on both vehicles involved in the jump start procedure. Put the automatic transmission in PARK (P), or a manual transmission in NEUTRAL (N) before setting the parking brake.

If you have a four wheel drive vehicle, be sure the transfer case is in a drive gear not in NEUTRAL.

NOTICE:

If you leave your radio on, it could be badly damaged. The repairs wouldn’t be covered by your warranty.

3. Turn off the ignition on both vehicles. Unplug unnecessary accessories plugged into the cigarette lighter or in the accessory power outlets. Turn off the radio and all the lamps that aren’t needed. This will avoid sparks and help save both batteries. And it could save your radio!

4. Open the hoods and locate the positive (+) and negative ( ) terminal locations of the other vehicle.

Your vehicle has a remote positive (+) jump starting terminal and a remote negative ( ) jump starting terminal. You should always use these remote terminals instead of the terminals on the battery.

The remote positive (+) terminal is located behind a red plastic cover near the engine accessory drive bracket. To uncover the remote positive (+) terminal, open the red plastic cover.

The remote negative ( ) terminal is located on the engine drive bracket on all V8 diesel engines.

On V8 engines it is marked “GND.”

On V6 engines the remote negative ( ) terminal is located on a tab attached to the engine accessory drive bracket where it is marked “GND.”

See “Engine Compartment Overview” in the Index for more information on location.

5-4

CAUTION:

Using a match near a battery can cause battery gas to explode. People have been hurt doing this, and some have been blinded. Use a flashlight if you need more light.

Be sure the batteries have enough water. You don’t need to add water to the ACDelco

R

battery

(or batteries) installed in every new GM vehicle.

But if a battery has filler caps, be sure the right amount of fluid is there. If it is low, add water to take care of that first. If you don’t, explosive gas could be present.

Battery fluid contains acid that can burn you.

Don’t get it on you. If you accidentally get it in your eyes or on your skin, flush the place with water and get medical help immediately.

CAUTION:

Fans or other moving engine parts can injure you badly. Keep your hands away from moving parts once the engine is running.

5. Check that the jumper cables don’t have loose or missing insulation. If they do, you could get a shock.

The vehicles could be damaged too.

Before you connect the cables, here are some basic things you should know. Positive (+) will go to positive (+) or a remote positive (+) terminal if the vehicle has one. Negative ( ) will go to a heavy, unpainted metal engine part or a remote negative ( ) terminal if the vehicle has one.

Don’t connect positive (+) to negative ( ) or you’ll get a short that would damage the battery and maybe other parts too. And don’t connect the negative ( ) cable to the negative ( ) terminal on the dead battery because this can cause sparks.

5-5

5-6

6. Connect the red positive (+) cable to the positive (+) terminal of the vehicle with the dead battery. Use a remote positive (+) terminal if the vehicle has one.

8. Now connect the black negative ( ) cable to the good battery’s negative ( ) cable. Use a remote negative ( ) terminal if the vehicle has one.

7. Don’t let the other end touch metal. Connect it to the positive (+) terminal of the good battery. Use a remote positive (+) terminal if the vehicle has one.

Don’t let the other end touch anything until the next step. The other end of the negative ( ) cable doesn’t go to the dead battery. It goes to a heavy, unpainted metal part, or to the remote negative ( ) terminal on the vehicle with the dead battery.

9. Connect the other end of the negative ( ) cable to the negative ( ) terminal of the dead battery or to a remote negative ( ) terminal if the vehicle has one.

NOTICE:

Damage to your vehicle may result from electrical shorting if jumper cables are removed incorrectly. To prevent electrical shorting take care that they don’t touch each other or any other metal. The repairs wouldn’t be covered by your warranty.

10. Now start the vehicle with the good battery and run the engine for a while.

11. Try to start the vehicle that had the dead battery.

If it won’t start after a few tries, it probably needs service.

C. Dead Battery or Remote Positive (+) Terminal

To disconnect the jumper cables from both vehicles do the following:

1. Disconnect the black negative ( ) cable from the vehicle that had the bad battery.

2. Disconnect the black negative ( ) cable from vehicle with the good battery.

3. Disconnect the red positive (+) cable from the vehicle with the good battery.

4. Disconnect the red positive (+) cable from the other vehicle.

5. Return the positive (+) remote terminal cover to its original position.

Towing Your Vehicle

Consult your dealer or a professional towing service if you need to have your disabled vehicle towed. See

“Roadside Assistance” in the Index. If you want to tow your vehicle behind another vehicle for recreational purposes (such as behind a motorhome), see

“Recreational Vehicle Towing” in the Index.

Engine Overheating

You will find a coolant temperature gage on your vehicle’s instrument panel. See “Engine Coolant

Temperature Gage” in the Index. In addition, you will find a LOW COOLANT, CHECK COOLANT TEMP,

ENGINE OVERHEATED and a REDUCED ENGINE

POWER message in the message center on the instrument panel. See “Message Center” in the Index.

Overheated Engine Protection Operating

Mode (V8 Engines Only)

If an overheated engine condition exists and the

REDUCED ENGINE POWER message is displayed, an overheat protection mode which alternates firing groups of cylinders helps prevent engine damage. In this mode, you will notice a loss in power and engine performance.

This operating mode allows your vehicle to be driven to a safe place in an emergency. Driving extended miles

(km) and/or towing a trailer in the overheat protection mode should be avoided.

NOTICE:

After driving in the overheated engine protection operating mode, to avoid engine damage, allow the engine to cool before attempting any repair.

The engine oil will be severely degraded. Repair the cause of coolant loss, change the oil and reset the oil life system. Repair the cause of coolant loss and change the oil. See “Engine Oil” in the Index.

5-9

If Steam Is Coming From Your Engine

CAUTION: (Continued)

Just turn it off and get everyone away from the vehicle until it cools down. Wait until there is no sign of steam or coolant before you open the hood.

If you keep driving when your engine is overheated, the liquids in it can catch fire. You or others could be badly burned. Stop your engine if it overheats, and get out of the vehicle until the engine is cool. See “Overheated Engine

Protection Operating Mode” in the Index.

CAUTION:

Steam from an overheated engine can burn you badly, even if you just open the hood. Stay away from the engine if you see or hear steam coming from it.

CAUTION: (Continued)

5-10

NOTICE:

If your engine catches fire because you keep driving with no coolant, your vehicle can be badly damaged. The costly repairs would not be covered by your warranty. See “Overheated

Engine Protection Operating Mode” in the Index.

If No Steam Is Coming From Your Engine

An overheat warning, along with a low coolant message, can indicate a serious problem. See “Low Coolant

Message” in the Index.

If you get an engine overheat warning with no low coolant message, but see or hear no steam, the problem may not be too serious. Sometimes the engine can get a little too hot when you:

D Climb a long hill on a hot day.

D Stop after high speed driving.

D Idle for long periods in traffic.

D Tow a trailer. See “Driving on Grades” in the Index.

If you get the overheat warning with no sign of steam, try this for a minute or so:

1. If you have an air conditioner and it’s on, turn it off.

2. Turn on your heater to full hot at the highest fan speed and open the window as necessary.

3. If you’re in a traffic jam, shift to NEUTRAL (N); otherwise, shift to the highest gear while driving - DRIVE (D).

If you no longer have the overheat warning, you can drive. Just to be safe, drive slower for about 10 minutes.

If the warning doesn’t come back on, you can drive normally.

If the warning continues, pull over, stop, and park your vehicle right away.

If there’s still no sign of steam, push down the accelerator until the engine speed is about twice as fast as normal idle speed for at least three minutes while you’re parked. If you still have the warning, turn off the

engine and get everyone out of the vehicle until it cools down. Also, see “Overheated Engine Protection

Operating Mode” listed previously in this section.

You may decide not to lift the hood but to get service help right away.

5-11

Cooling System

When you decide it’s safe to lift the hood, here’s what you’ll see:

5-12

8100 V8 Engines

All Other Engines

A. Coolant Surge Tank

B. Coolant Surge Tank Pressure Cap

C. Engine Fan

If the coolant inside the coolant surge tank is boiling, don’t do anything else until it cools down. The vehicle should be parked on a level surface.

The coolant level should be at or above the FILL COLD mark. If it isn’t, you may have a leak at the pressure cap or in the radiator hoses, heater hoses, radiator, water pump or somewhere else in the cooling system.

CAUTION:

Heater and radiator hoses, and other engine parts, can be very hot. Don’t touch them. If you do, you can be burned.

Don’t run the engine if there is a leak. If you run the engine, it could lose all coolant. That could cause an engine fire, and you could be burned.

Get any leak fixed before you drive the vehicle.

If there seems to be no leak, start the engine again. The engine cooling fan speed should increase when idle speed is doubled by pushing the accelerator pedal down. If it doesn’t, your vehicle needs service. Turn off the engine.

NOTICE:

Engine damage from running your engine without coolant isn’t covered by your warranty.

See “Overheated Engine Protection Operating

Mode” in the Index.

NOTICE:

When adding coolant, it is important that you use only DEX COOL

R

(silicate free) coolant.

If coolant other than DEX COOL is added to the system, premature engine, heater core or radiator corrosion may result. In addition, the engine coolant will require change sooner - at

30,000 miles (50 000 km) or 24 months, whichever occurs first. Damage caused by the use of coolant other than DEX COOL

R

is not covered by your new vehicle warranty.

5-13

How to Add Coolant to the Coolant

Surge Tank

If you haven’t found a problem yet, check to see if coolant is visible in the surge tank. If coolant is visible but the coolant level isn’t at or above the FILL COLD mark, add a 50/50 mixture of clean, drinkable water and

DEX COOL

R

coolant at the coolant surge tank, but be sure the cooling system, including the coolant surge tank pressure cap, is cool before you do it. See “Engine

Coolant” in the Index for more information.

If no coolant is visible in the surge tank, add coolant as follows:

CAUTION:

Steam and scalding liquids from a hot cooling system can blow out and burn you badly. They are under pressure, and if you turn the coolant surge tank pressure cap - even a little - they can come out at high speed. Never turn the cap when the cooling system, including the coolant surge tank pressure cap, is hot. Wait for the cooling system and coolant surge tank pressure cap to cool if you ever have to turn the pressure cap.

5-14

CAUTION:

Adding only plain water to your cooling system can be dangerous. Plain water, or some other liquid such as alcohol, can boil before the proper coolant mixture will. Your vehicle’s coolant warning system is set for the proper coolant mixture. With plain water or the wrong mixture, your engine could get too hot but you wouldn’t get the overheat warning. Your engine could catch fire and you or others could be burned.

Use a 50/50 mixture of clean, drinkable water and DEX COOL

R

coolant.

CAUTION:

You can be burned if you spill coolant on hot engine parts. Coolant contains ethylene glycol and it will burn if the engine parts are hot enough. Don’t spill coolant on a hot engine.

NOTICE:

In cold weather, water can freeze and crack the engine, radiator, heater core and other parts. So use the recommended coolant.

5-15

Your vehicle may be equipped with one of the two caps shown.

1. Park the vehicle on a level surface. You can remove the coolant surge tank pressure cap when the cooling system, including the coolant surge tank pressure cap and upper radiator hose, is no longer hot. Turn the pressure cap slowly counterclockwise (left) about one full turn. If you hear a hiss, wait for that to stop.

A hiss means there is still some pressure left.

2. Then keep turning the pressure cap slowly, and remove it.

3. Then fill the coolant surge tank with the proper mixture, to the FILL COLD mark.

5-16

4. With the coolant surge tank pressure cap off, start the engine and let it run until you can feel the upper radiator hose getting hot. Watch out for the engine cooling fan.

By this time, the coolant level inside the coolant surge tank may be lower. If the level is lower, add more of the proper mixture to the coolant surge tank until the level reaches the FILL COLD mark.

5. Then replace the pressure cap. Be sure the pressure cap is hand tight and fully seated.

5-17

Engine Fan Noise

Your vehicle has a clutched engine cooling fan. When the clutch is engaged, the fan spins faster to provide more air to cool the engine. In most everyday driving conditions, the fan is spinning slower and the clutch is not fully engaged. This improves fuel economy and reduces fan noise. Under heavy vehicle loading, trailer towing and/or high outside temperatures, the fan speed increases as the clutch more fully engages. So you may hear an increase in fan noise. This is normal and should not be mistaken as the transmission slipping or making extra shifts. It is merely the cooling system functioning properly. The fan will slow down when additional cooling is not required and the clutch disengages.

You may also hear this fan noise when you start the engine. It will go away as the fan clutch partially disengages.

If a Tire Goes Flat

It’s unusual for a tire to “blow out” while you’re driving, especially if you maintain your tires properly. If air goes out of a tire, it’s much more likely to leak out slowly.

But if you should ever have a “blowout,” here are a few tips about what to expect and what to do:

If a front tire fails, the flat tire will create a drag that pulls the vehicle toward that side. Take your foot off the accelerator pedal and grip the steering wheel firmly.

Steer to maintain lane position, and then gently brake to a stop well out of the traffic lane.

A rear blowout, particularly on a curve, acts much like a skid and may require the same correction you’d use in a skid. In any rear blowout, remove your foot from the accelerator pedal. Get the vehicle under control by steering the way you want the vehicle to go. It may be very bumpy and noisy, but you can still steer. Gently brake to a stop - well off the road if possible.

If a tire goes flat, the next part shows how to use your jacking equipment to change a flat tire safely.

5-18

Changing a Flat Tire

If a tire goes flat, avoid further tire and wheel damage by driving slowly to a level place. Turn on your hazard warning flashers.

CAUTION:

Changing a tire can cause an injury. The vehicle can slip off the jack and roll over you or other people. You and they could be badly injured.

Find a level place to change your tire. To help prevent the vehicle from moving:

1. Set the parking brake firmly.

2. Put an automatic transmission shift lever in PARK (P) or shift a manual transmission to FIRST (1) or REVERSE (R).

3. Turn off the engine.

4. Put the wheel blocks at the front and rear of the tire farthest away from the one being changed. That would be the tire on the other side of the vehicle, at the opposite end.

The following steps will tell you how to use the jack and change a tire.

Follow these instructions to lower the spare tire:

1. If the vehicle is equipped with a hoist lock, open the spare tire lock cover on the bumper and use the ignition key to remove the lock.

2. Assemble the wheel wrench and the two jack handle extensions as shown. Insert the hoist end (open end) of the extension through the hole in the rear bumper.

Be sure the hoist end of the extension connects into the hoist shaft (the ribbed square end of the extension is used to lower the spare tire).

3. Turn the wheel wrench counterclockwise to lower the spare tire to the ground. Continue to turn the wheel wrench until the spare tire can be pulled out from under the vehicle. The wheel wrench has a hook that allows you to pull the hoist cable towards you, to assist in reaching the spare tire.

4. When the tire has been lowered, tilt the retainer at the end of the cable so it can be pulled up through the wheel opening.

5. Put the spare tire near the flat tire.

The tools you’ll be using include the bottle jack (A), the wheel blocks (B), the jack handle (C), the jack handle extensions (D), and the wheel wrench (E).

If the flat tire is on the rear of the vehicle, you’ll need to use both jack handle extensions.

5-23

Attach the wheel wrench to the jack handle extensions

(as needed). Attach the jack handle to the jack.

Turn the wheel wrench clockwise to raise the jack lift head to the lifting point.

5-24

If your vehicle has wheel nut caps, loosen them by turning the wheel wrench counterclockwise. If you have a center cap with wheel nut caps, the wheel nut caps are designed to remain with the center cap.

Remove the center cap.

Removing the Flat Tire and Installing the

Spare Tire

1. Use the wheel wrench to loosen all the wheel nuts. Turn the wheel wrench counterclockwise to loosen the wheel nuts.

Don’t remove the wheel nuts yet.

If the wheel has a smooth center piece, place the chisel end of the wheel wrench in the slot on the wheel and gently pry out.

5-25

CAUTION:

Getting under a vehicle when it is jacked up is dangerous. If the vehicle slips off the jack, you could be badly injured or killed. Never get under a vehicle when it is supported only by a jack.

2. Position the jack under the vehicle. If the flat tire is on the front of the vehicle, position the jack on the frame behind the flat tire where the frame sections overlap.

On all 1500 series vehicles, use the jacking pad provided on the rear axle. On 2500 series vehicles, use the axle between the spring and shock.

If you have added a snow plow to the front of your vehicle, lower the snow plow fully before raising the vehicle.

CAUTION:

Raising your vehicle with the jack improperly positioned can damage the vehicle and even make the vehicle fall. To help avoid personal injury and vehicle damage, be sure to fit the jack lift head into the proper location before raising the vehicle.

3. Make sure the jack head is positioned so that the rear axle is resting securely between the grooves that are on the jack head. Turn the wheel wrench clockwise to raise the vehicle. Raise the vehicle far enough off the ground so there is enough room for the spare tire to fit back underneath the rear of the vehicle.

5-27

5-28

4. Remove all the wheel nuts and take off the flat tire.

5. Remove any rust or dirt from the wheel bolts, mounting surfaces and spare wheel.

CAUTION:

Rust or dirt on the wheel, or on the parts to which it is fastened, can make the wheel nuts become loose after a time. The wheel could come off and cause an accident. When you change a wheel, remove any rust or dirt from the places where the wheel attaches to the vehicle. In an emergency, you can use a cloth or a paper towel to do this; but be sure to use a scraper or wire brush later, if you need to, to get all the rust or dirt off.

CAUTION:

Never use oil or grease on studs or nuts. If you do, the nuts might come loose. Your wheel could fall off, causing a serious accident.

6. After mounting the spare, put the wheel nuts back on with the rounded end of the nuts toward the wheel. Tighten each wheel nut by hand using the wheel wrench until the wheel is held against the hub.

7. Turn the wheel wrench counterclockwise to lower the vehicle. Lower the jack completely.

8. Tighten the nuts firmly in a crisscross sequence as shown by turning the wheel wrench clockwise.

5-30

CAUTION:

Incorrect wheel nuts or improperly tightened wheel nuts can cause the wheel to become loose and even come off. This could lead to an accident.

Be sure to use the correct wheel nuts. If you have to replace them, be sure to get new GM original equipment wheel nuts.

Stop somewhere as soon as you can and have the nuts tightened with a torque wrench to the proper torque. See “Capacities and

Specifications” in the Index.

Storing a Flat or Spare Tire and Tools

CAUTION:

Storing a jack, a tire or other equipment in the passenger compartment of the vehicle could cause injury. In a sudden stop or collision, loose equipment could strike someone. Store all these in the proper place.

NOTICE:

Improperly tightened wheel nuts can lead to brake pulsation and rotor damage. To avoid expensive brake repairs, evenly tighten the wheel nuts in the proper sequence and to the proper torque specification.

5-31

Store the flat tire where the spare tire was stored.

To store the tire:

1. Put the tire on the ground at the rear of the vehicle with the valve stem pointed upward.

2. Tilt the retainer downward and through the wheel opening. Make sure the retainer is fully seated across the underside of the wheel.

3. Attach the wheel wrench and extensions together.

Insert the hoist end through the hole in the rear bumper and into the hoist shaft.

4. Raise the tire part way upward. Make sure the retainer is seated in the wheel opening.

5. Raise the tire fully against the underside of the vehicle. Continue turning the wheel wrench until the tire is secure and the cable is tight. The spare tire hoist cannot be overtightened.

6. Make sure the tire is stored securely. Push, pull, and then try to rotate or turn the tire. If the tire moves, use the wheel wrench to tighten the cable.

Put back the jack, tools and spare tire lock.

Spare Tire

Your vehicle, when new, had a fully inflated spare tire.

A spare tire may lose air over time, so check its inflation pressure regularly. See “Inflation Tire Pressure” and

“Loading Your Vehicle” in the Index for information regarding proper tire inflation and loading your vehicle.

For instruction on how to remove, install or store a spare tire, see “Changing a Flat Tire” in the Index.

After installing the spare tire on your vehicle, you should stop as soon as possible and make sure the spare is correctly inflated. Have the damaged or flat road tire repaired or replaced as soon as you can and installed back onto your vehicle. This way, a spare tire will be available in case you need it again.

If You’re Stuck: In Sand, Mud,

Ice or Snow

In order to free your vehicle when it is stuck, you will need to spin the wheels, but you don’t want to spin your wheels too fast. The method known as “rocking” can help you get out when you’re stuck, but you must use caution.

CAUTION:

If you let your tires spin at high speed, they can explode, and you or others could be injured. And, the transmission or other parts of the vehicle can overheat. That could cause an engine compartment fire or other damage. When you’re stuck, spin the wheels as little as possible. Don’t spin the wheels above 35 mph (55 km/h) as shown on the speedometer.

5-36

NOTICE:

Spinning your wheels can destroy parts of your vehicle as well as the tires. If you spin the wheels too fast while shifting your transmission back and forth, you can destroy your transmission.

For information about using tire chains on your vehicle, see “Tire Chains” in the Index.

Rocking Your Vehicle To Get It Out

First, turn your steering wheel left and right. That will clear the area around your front wheels. If you have a four wheel drive vehicle, shift into 4HI or 4LO. If your vehicle has the Traction Assist System, you should turn it off by pressing the TAS on/off button. Then shift back and forth between REVERSE (R) and a forward gear, spinning the wheels as little as possible. Release the accelerator pedal while you shift, and press lightly on the accelerator pedal when the transmission is in gear. By slowly spinning your wheels in the forward and reverse directions, you will cause a rocking motion that may free your vehicle. If that doesn’t get you out after a few tries, you may need to be towed out. Or, you can use your recovery hooks if your vehicle has them. If you do need to be towed out, see

“Towing Your Vehicle” in the Index.

Using the Recovery Hooks

Your vehicle may be equipped with recovery hooks. The hooks are provided at the front of your vehicle. You may need to use them if you’re stuck off road and need to be pulled to some place where you can continue driving.

5-37

5-38

CAUTION:

These hooks, when used, are under a lot of force.

Always pull the vehicle straight out. Never pull on the hooks at a sideways angle. The hooks could break off and you or others could be injured from the chain or cable snapping back.

NOTICE:

Never use the recovery hooks to tow the vehicle.

Your vehicle could be damaged and it would not be covered by warranty.

Service

Your dealer knows your vehicle best and wants you to be happy with it. We hope you’ll go to your dealer for all your service needs. You’ll get genuine GM parts and

GM trained and supported service people.

We hope you’ll want to keep your GM vehicle all GM.

Genuine GM parts have one of these marks:

Doing Your Own Service Work

If you want to do some of your own service work, you’ll want to use the proper service manual. It tells you much more about how to service your vehicle than this manual can. To order the proper service manual, see “Service and Owner Publications” in the Index.

Your vehicle has an air bag system. Before attempting to do your own service work, see “Servicing Your Air

Bag Equipped Vehicle” in the Index.

You should keep a record with all parts receipts and list the mileage and the date of any service work you perform. See “Maintenance Record” in the Index.

6-2

CAUTION:

You can be injured and your vehicle could be damaged if you try to do service work on a vehicle without knowing enough about it.

D Be sure you have sufficient knowledge, experience, the proper replacement parts and tools before you attempt any vehicle maintenance task.

D Be sure to use the proper nuts, bolts and other fasteners. “English” and “metric” fasteners can be easily confused. If you use the wrong fasteners, parts can later break or fall off. You could be hurt.

Adding Equipment to the Outside of

Your Vehicle

Things you might add to the outside of your vehicle can affect the airflow around it. This may cause wind noise and affect windshield washer performance. Check with your dealer before adding equipment to the outside of your vehicle.

Fuel (Gasoline)

The 8th digit of your vehicle identification number

(VIN) shows the code letter or number that identifies your engine. You will find the VIN at the top left of the instrument panel. See “Vehicle Identification Number” in the Index.

If your vehicle has the 5.3L V8 engine (VIN Code Z only), you may use either regular unleaded gasoline or ethanol fuel containing up to 85% ethanol (E 85); also see “Fuel E 85 (85% Ethanol)” following. In all other engines, including the 5.3L V8 (VIN Code T), use only regular unleaded gasoline.

Gasoline Octane

Use regular unleaded gasoline with a posted octane of

87 or higher. If the octane is less than 87, you may get a heavy knocking noise when you drive. If it is bad enough, it can damage your engine. A little pinging noise when you accelerate or drive uphill is considered normal. This does not indicate a problem exists or that a higher octane fuel is necessary.

6-3

Gasoline Specifications

It is recommended that gasoline meet specifications which were developed by the American Automobile

Manufacturers Association and endorsed by the

Canadian Vehicle Manufacturers’ Association for better vehicle performance and engine protection. Gasolines meeting these specifications could provide improved driveability and emission control system performance compared to other gasolines.

In Canada, look for the “Auto Makers’

Choice” label on the pump.

California Fuel

If your vehicle is certified to meet California Emission

Standards (see the underhood emission control label), it is designed to operate on fuels that meet California specifications. If this fuel is not available in states adopting California emissions standards, your vehicle will operate satisfactorily on fuels meeting federal specifications, but emission control system performance may be affected. The malfunction indicator lamp may turn on (see “Malfunction Indicator Lamp” in the Index) and your vehicle may fail a smog check test. If this occurs, return to your authorized GM dealer for diagnosis. If it is determined that the condition is caused by the type of fuel used, repairs may not be covered by your warranty.

6-4

Canada Only

Additives

Some gasolines that are not reformulated for low emissions may contain an octane enhancing additive called methylcyclopentadienyl manganese tricarbonyl

(MMT); ask the attendant where you buy gasoline whether the fuel contains MMT. General Motors does not recommend the use of such gasolines. Fuels containing MMT can reduce the life of spark plugs and the performance of the emission control system may be affected. The malfunction indicator lamp may turn on.

If this occurs, return to your authorized GM dealer for service.

To provide cleaner air, all gasolines in the United States are now required to contain additives that will help prevent engine and fuel system deposits from forming, allowing your emission control system to work properly.

You should not have to add anything to your fuel.

Gasolines containing oxygenates, such as ethers and ethanol, and reformulated gasolines may be available in your area to contribute to clean air. General Motors recommends that you use these gasolines, particularly if they comply with the specifications described earlier.

NOTICE:

Your vehicle was not designed for fuel that contains methanol. Don’t use fuel containing methanol. It can corrode metal parts in your fuel system and also damage plastic and rubber parts. That damage wouldn’t be covered under your warranty.

Fuel E

-

85 (85% Ethanol)

The 8th digit of your vehicle identification number

(VIN) shows the code letter or number that identifies your engine. You will find the VIN at the top left of the instrument panel. See “Vehicle Identification Number” in the Index.

If your vehicle has the 5.3L V8 engine (VIN Code Z only), you may use either regular unleaded gasoline or ethanol fuel containing up to 85% ethanol (E 85); also see “Fuel (Gasoline)” listed previously. In all other engines, including the 5.3L V8 (Code T), use only regular unleaded gasoline.

6-5

Only vehicles that have the 5.3L V8 engine

(VIN Code Z) may use 85% ethanol fuel (E 85).

Many service stations will not have an 85% ethanol fuel (E 85) pump available. The U. S. Department of Energy has an alternative fuels website

(http://afdcmap.nrel.gov/nrel/) that can help you find

E 85 fuel. Those stations that do have E 85 should have a label indicating ethanol content. Do not use the fuel if the ethanol content is greater than 85%.

Your vehicle may not operate properly if the ethanol content is greater than 85%.

At a minimum, E 85 should meet ASTM

Specification D 5798.

To insure quick starts in the wintertime, the E 85 fuel must be formulated properly for your climate according to ASTM specification D 5798. If you have trouble starting on E 85, it may be because your E 85 fuel is not properly formulated for your climate. If this happens, switching to gasoline or adding gasoline to your fuel tank may improve starting. Your vehicle is designed to accommodate a mixture of gasoline and E 85 fuel. For good starting and heater efficiency below 32

_F (0_C), the fuel mix in the fuel tank should contain no more than

70% ethanol.

E 85 has less energy per gallon than gasoline, so you’ll need to refill your fuel tank more often when using E 85 than when you’re using gasoline. Regular unleaded gasoline is recommended when pulling a trailer. For payload capacity with ethanol fuel see “Loading Your

Vehicle” in the Index.

NOTICE:

Some additives are not compatible with E 85 fuel and may harm your fuel system. Damage caused by additives wouldn’t be covered by your new vehicle warranty. Don’t use additives with E 85 fuel.

NOTICE:

Your vehicle was not designed for fuel that contains methanol. It can corrode metal parts in your fuel system and also damage plastic and rubber parts.

That damage wouldn’t be covered under your warranty. Don’t use fuel containing methanol.

6-6

Fuels in Foreign Countries

If you plan on driving in another country outside the

United States or Canada, the proper fuel may be hard to find. Never use leaded gasoline or any other fuel not recommended in the previous text on fuel. Costly repairs caused by use of improper fuel wouldn’t be covered by your warranty.

To check on fuel availability, ask an auto club, or contact a major oil company that does business in the country where you’ll be driving.

Filling Your Tank

CAUTION:

Gasoline vapor is highly flammable. It burns violently, and that can cause very bad injuries.

Don’t smoke if you’re near gasoline or refueling your vehicle. Keep sparks, flames and smoking materials away from gasoline.

The fuel cap is located on the driver’s side of your vehicle.

6-7

While refueling, hang the fuel cap by the tether using the hook located on the inside of the filler door.

To remove the fuel cap, turn it slowly to the left (counterclockwise).

CAUTION:

If you get gasoline on yourself and then something ignites it, you could be badly burned.

Gasoline can spray out on you if you open the fuel cap too quickly. This spray can happen if your tank is nearly full, and is more likely in hot weather. Open the fuel cap slowly and wait for any “hiss” noise to stop. Then unscrew the cap all the way.

Be careful not to spill gasoline. Clean gasoline from painted surfaces as soon as possible. See “Cleaning the

Outside of Your Vehicle” in the Index.

6-8

When you put the fuel cap back on, turn it to the right

(clockwise) until you hear a clicking sound. Make sure you fully install the cap. The diagnostic system can determine if the fuel cap has been left off or improperly installed. This would allow fuel to evaporate into the atmosphere. See “Malfunction Indicator Lamp” in the Index.

NOTICE:

If you need a new fuel cap, be sure to get the right type. Your dealer can get one for you. If you get the wrong type, it may not fit properly. This may cause your malfunction indicator lamp to light and may damage your fuel tank and emissions system. See “Malfunction Indicator

Lamp” in the Index.

Filling a Portable Fuel Container

CAUTION:

Never fill a portable fuel container while it is in your vehicle. Static electricity discharge from the container can ignite the gasoline vapor. You can be badly burned and your vehicle damaged if this occurs. To help avoid injury to you and others:

D Dispense gasoline only into approved containers.

D Do not fill a container while it is inside a vehicle, in a vehicle’s trunk, pickup bed or on any surface other than the ground.

D Bring the fill nozzle in contact with the inside of the fill opening before operating the nozzle. Contact should be maintained until the filling is complete.

D Don’t smoke while pumping gasoline.

6-9

Checking Things Under the Hood

CAUTION:

Things that burn can get on hot engine parts and start a fire. These include liquids like fuel, oil, coolant, brake fluid, windshield washer and other fluids, and plastic or rubber. You or others could be burned. Be careful not to drop or spill things that will burn onto a hot engine.

Hood Release

To open the hood do the following:

1. Pull the handle inside the vehicle located under and to the left of the steering wheel.

6-10

2. Then go to the front of the vehicle and pull up on the secondary hood release located near the center of the grill.

3. Lift the hood.

Before closing the hood, be sure all filler caps are on properly. Pull down the hood and close it firmly.

Engine Oil

If the CHECK ENG OIL

LEVEL message appears on the instrument cluster, it means you need to check your engine oil level right away.

For more information, see “CHECK ENG OIL LEVEL” in the Index.

You should check your engine oil level regularly; this is an added reminder.

Checking Engine Oil

It’s a good idea to check your engine oil every time you get fuel. In order to get an accurate reading, the oil must be warm and the vehicle must be on level ground.

8100 Engines All Other Engines

The engine oil dipstick has a yellow ring handle and is located in the engine compartment on the passenger’s side of the vehicle. See “Engine

Compartment Overview” in the Index for more information on location.

6-15

Turn off the engine and give the oil several minutes to drain back into the oil pan. If you don’t, the oil dipstick might not show the actual level.

Pull out the dipstick and clean it with a paper towel or cloth, then push it back in all the way. Remove it again, keeping the tip down, and check the level.

When to Add Engine Oil

If the oil is at or below the ADD mark, then you’ll need to add at least one quart of oil. But you must use the right kind. This part explains what kind of oil to use.

For engine oil crankcase capacity, see “Capacities and

Specifications” in the Index.

NOTICE:

Don’t add too much oil. If your engine has so much oil that the oil level gets above the cross hatched area that shows the proper operating range, your engine could be damaged.

6-16

8100 Engines All Other Engines

The engine oil fill cap for the VORTEC 4800,

5300, 6000 and 8100 V8 engines is located on the engine valve cover, on the passenger’s side of the vehicle.

Your vehicle may have a cap with text and a graphic, or just a graphic as shown. See “Engine Compartment

Overview” in the Index for more information on location.

Be sure to fill it enough to put the level somewhere in the proper operating range. Push the dipstick all the way back in when you’re through.

6-17

What Kind of Engine Oil to Use

Oils recommended for your vehicle can be identified by looking for the starburst symbol.

This symbol indicates that the oil has been certified by the American Petroleum Institute (API). Do not use any oil which does not carry this starburst symbol.

If you change your own oil, be sure you use oil that has the starburst symbol on the front of the oil container. If you have your oil changed for you, be sure the oil put into your engine is

American Petroleum

Institute certified for gasoline engines.

You should also use the proper viscosity oil for your vehicle, as shown in the following chart:

6-18

As in the chart shown previously, SAE 5W 30 is best for your vehicle. However, you can use SAE 10W going to be 0

_F (

30 if it’s

18

_C) or above. These numbers on an oil container show its viscosity, or thickness. Do not use other viscosity oils, such as SAE 20W 50.

NOTICE:

Use only engine oil with the American Petroleum

Institute Certified For Gasoline Engines starburst symbol. Failure to use the recommended oil can result in engine damage not covered by your warranty.

GM Goodwrench

R

oil meets all the requirements for your vehicle.

If you are in an area where the temperature falls below

20

_F ( 29

_C), consider using either an SAE 5W 30 synthetic oil or an SAE 0W 30 oil. Both will provide easier cold starting and better protection for your engine at extremely low temperatures.

Engine Oil Additives

Don’t add anything to your oil. The recommended oils with the starburst symbol are all you will need for good performance and engine protection.

When to Change Engine Oil

(GM Oil Life System

t)

Your vehicle has a computer system that lets you know when to change the engine oil and filter. This is based on engine revolutions and engine temperature, and not on mileage. Based on driving conditions, the mileage at which an oil change will be indicated can vary considerably. For the oil life system to work properly, you must reset the system every time the oil is changed.

When the system has calculated that oil life has been diminished, it will indicate that an oil change is necessary. A CHANGE ENGINE OIL message will come on. Change your oil as soon as possible within the next two times you stop for fuel. It is possible that, if you are driving under the best conditions, the oil life system may not indicate that an oil change is necessary for over a year. However, your engine oil and filter must be changed at least once a year and at this time the system must be reset. It is also important to check your oil regularly and keep it at the proper level.

If the system is ever reset accidentally, you must change your oil at 3,000 miles (5 000 km) since your last oil change. Remember to reset the oil life system whenever the oil is changed.

6-19

How to Reset the CHANGE ENGINE OIL Message

The GM Oil Life System t calculates when to change your engine oil and filter based on vehicle use.

Anytime your oil is changed, reset the system so it can calculate when the next oil change is required. If a situation occurs where you change your oil prior to a

CHANGE ENGINE OIL message being turned on, reset the system.

To reset the CHANGE ENGINE OIL message do the following:

1. Turn the ignition key to RUN with the engine off.

2. Fully press and release the accelerator pedal three times within five seconds.

If the CHANGE ENGINE OIL message flashes for five seconds, the system is reset.

What to Do with Used Oil

Used engine oil contains certain elements that may be unhealthy for your skin and could even cause cancer.

Don’t let used oil stay on your skin for very long. Clean your skin and nails with soap and water, or a good hand cleaner. Wash or properly throw away clothing or rags containing used engine oil. See the manufacturer’s warnings about the use and disposal of oil products.

Used oil can be a threat to the environment. If you change your own oil, be sure to drain all the oil from the filter before disposal. Never dispose of oil by putting it in the trash, pouring it on the ground, into sewers, or into streams or bodies of water. Instead, recycle it by taking it to a place that collects used oil. If you have a problem properly disposing of your used oil, ask your dealer, a service station or a local recycling center for help.

6-20

Engine Air Cleaner/Filter

The engine air cleaner/filter assembly has an indicator that lets you know when the air filter is dirty and needs to be serviced. The indicator is located on the air cleaner cover. See “Engine Compartment Overview” in the

Index for more information on location.

See “Owner Checks and Services” in the Index to determine when to check the indicator.

The service window A with the percentage scale shows the amount of engine air cleaner/filter life used.

When both service window A and service window B turn orange, replace the engine air cleaner/filter.

Your engine air cleaner/filter is located in the front corner of the engine compartment on the passenger’s side of the vehicle. See “Engine Compartment

Overview” in the Index for more information on location.

After changing the air filter, press the top button on the indicator to reset it.

6-21

1. To remove the engine/air cleaner filter, loosen the screws on the housing cover.

2. Then lift the cover upward and remove the filter from the housing. Care should be taken to dislodge as little dirt as possible.

3. Clean the filter sealing surface and the filter housing.

4. Install the new filter.

5. Reinstall the housing cover.

Refer to the Maintenance Schedule to determine when to replace the air filter. See “Owner Checks and Services” in the Index.

CAUTION:

Operating the engine with the air cleaner/filter off can cause you or others to be burned. The air cleaner not only cleans the air, it stops flame if the engine backfires. If it isn’t there, and the engine backfires, you could be burned. Don’t drive with it off, and be careful working on the engine with the air cleaner/filter off.

NOTICE:

If the air cleaner/filter is off, a backfire can cause a damaging engine fire. And, dirt can easily get into your engine, which will damage it.

Always have the air cleaner/filter in place when you’re driving.

6-22

Passenger Compartment Air Filter

(If Equipped)

Your vehicle may be equipped with a passenger compartment air filter. The filter is located under the instrument panel, below the glove compartment.

Your vehicle may or may not be equipped with an access panel.

To replace the passenger compartment air filter, do the following:

1. If your vehicle has an access panel, remove the bolts on it and set the panel aside. If your vehicle does not have the access panel, skip this step.

2. Next, pull downward on the filter retaining bracket.

3. Remove the air filter by pulling downward on the element. Remove the second portion of the air filter by sliding it towards the rear of the vehicle and then pulling downward.

4. Install the new filter by reversing the steps listed previously. Be sure to follow any instructions that may be included in the replacement filter package.

Because this procedure can be a little difficult, you may choose to have it done at your dealer’s service department.

Refer to the Maintenance Schedule to determine when to replace the passenger compartment air filter. See

“Scheduled Maintenance” in the Index.

6-23

Automatic Transmission Fluid

When to Check and Change

A good time to check your automatic transmission fluid level is when the engine oil is changed.

Change both the fluid and filter every 50,000 miles

(83 000 km) if the vehicle’s GVWR is over 8,600 or if the vehicle is mainly driven under one or more of these conditions:

D In heavy city traffic where the outside temperature regularly reaches 90

_F (32_C) or higher.

D In hilly or mountainous terrain.

D When doing frequent trailer towing.

D Uses such as found in taxi, police or delivery service.

If your vehicle’s GVWR is not over 8,600 and you do not use your vehicle under any of these conditions, change the fluid and filter every 100,000 miles (166 000 km).

See “Scheduled Maintenance Services” in the Index.

How to Check

Because this operation can be a little difficult, you may choose to have this done at the dealership service department.

If you do it yourself, be sure to follow all the instructions here, or you could get a false reading on the dipstick.

NOTICE:

Too much or too little fluid can damage your transmission. Too much can mean that some of the fluid could come out and fall on hot engine parts or exhaust system parts, starting a fire.

Too little fluid could cause the transmission to overheat. Be sure to get an accurate reading if you check your transmission fluid.

6-24

Wait at least 30 minutes before checking the transmission fluid level if you have been driving:

D When outside temperatures are above 90_F (32_C).

D At high speed for quite a while.

D In heavy traffic - especially in hot weather.

D While pulling a trailer.

To get the right reading, the fluid should be at normal operating temperature, which is 180

_F to 200

_F (82_C to 93_C).

Get the vehicle warmed up by driving about 15 miles

(24 km) when outside temperatures are above 50

_F

(10

_C). If it’s colder than 50_F (10_C), drive the vehicle in THIRD (3) until the engine temperature gage moves and then remains steady for 10 minutes.

A cold fluid check can be made after the vehicle has been sitting for eight hours or more with the engine off, but this is used only as a reference. Let the engine run at idle for five minutes if outside temperatures are 50

_F

(10

_C) or more. If it’s colder than 50_F (10_C), you may have to idle the engine longer. Should the fluid level be low during this cold check, you must check the fluid hot before adding fluid. Checking the fluid hot will give you a more accurate reading of the fluid level.

Checking the Fluid Level

Prepare your vehicle as follows:

D Park your vehicle on a level place. Keep the engine running.

D With the parking brake applied, place the shift lever in PARK (P).

D With your foot on the brake pedal, move the shift lever through each gear range, pausing for about three seconds in each range. Then, position the shift lever in PARK (P).

D Let the engine run at idle for three minutes or more.

6-25

Then, without shutting off the engine, follow these steps: 1. Flip the handle up and then pull out the dipstick and wipe it with a clean rag or paper towel.

2. Push it back in all the way, wait three seconds and then pull it back out again.

The red transmission dipstick handle with the

TRANS/LOCK text or graphic is located at the rear of the engine compartment, on the passenger’s side.

See “Engine Compartment Overview” in the Index for more information on location.

3. Check both sides of the dipstick, and read the lower level. The fluid level must be in the COLD area, below the cross–hatched area, for a cold check or in the HOT area or cross–hatched area for a hot check.

4. If the fluid level is in the acceptable range, push the dipstick back in all the way; then flip the handle down to lock the dipstick in place.

6-26

How to Add Fluid

Refer to the Maintenance Schedule to determine what kind of transmission fluid to use. See “Recommended

Fluids and Lubricants” in the Index.

Add fluid only after checking the transmission fluid while it is hot. (A cold check is used only as a reference.) If the fluid level is low, add only enough of the proper fluid to bring the level up to the HOT area for a hot check. It doesn’t take much fluid, generally less than one pint (0.5 L). Don’t overfill.

D After adding fluid, recheck the fluid level as described under “How to Check.”

D When the correct fluid level is obtained, push the dipstick back in all the way; then flip the handle down to lock the dipstick in place.

Engine Coolant

The cooling system in your vehicle is filled with

DEX COOL

R

engine coolant. This coolant is designed to remain in your vehicle for 5 years or 150,000 miles

(240 000 km), whichever occurs first, if you add only

DEX COOL

R

extended life coolant.

The following explains your cooling system and how to add coolant when it is low. If you have a problem with engine overheating, see “Engine Overheating” in the Index.

A 50/50 mixture of clean, drinkable water and

DEX COOL

R

coolant will:

D Give freezing protection down to 34

_F ( 37

_C).

D Give boiling protection up to 265_F (129_C).

D Protect against rust and corrosion.

D Help keep the proper engine temperature.

D Let the warning lights and gages work as they should.

NOTICE:

When adding coolant, it is important that you use only DEX COOL

R

(silicate free) coolant.

If coolant other than DEX COOL is added to the system, premature engine, heater core or radiator corrosion may result. In addition, the engine coolant will require change sooner - at

30,000 miles (50 000 km) or 24 months, whichever occurs first. Damage caused by the use of coolant other than DEX COOL

R

is not covered by your new vehicle warranty.

6-31

What to Use

Use a mixture of one half clean, drinkable water and one half DEX COOL

R

coolant which won’t damage aluminum parts. If you use this coolant mixture, you don’t need to add anything else.

CAUTION:

Adding only plain water to your cooling system can be dangerous. Plain water, or some other liquid such as alcohol, can boil before the proper coolant mixture will. Your vehicle’s coolant warning system is set for the proper coolant mixture. With plain water or the wrong mixture, your engine could get too hot but you wouldn’t get the overheat warning. Your engine could catch fire and you or others could be burned.

Use a 50/50 mixture of clean, drinkable water and DEX COOL

R

coolant.

NOTICE:

If you use an improper coolant mixture, your engine could overheat and be badly damaged.

The repair cost wouldn’t be covered by your warranty. Too much water in the mixture can freeze and crack the engine, radiator, heater core and other parts.

If you have to add coolant more than four times a year, have your dealer check your cooling system.

NOTICE:

If you use the proper coolant, you don’t have to add extra inhibitors or additives which claim to improve the system. These can be harmful.

6-32

Checking Coolant

The coolant surge tank is located in the engine compartment on the passenger’s side of the vehicle. See “Engine

Compartment Overview” in the Index for more information on location.

If the LOW COOLANT light comes on and stays on, it means you’re low on engine coolant.

See “Low Coolant” in the Index.

Adding Coolant

If you need more coolant, add the proper DEX COOL

R coolant mixture at the surge tank, but only when the engine is cool.

CAUTION:

Turning the surge tank pressure cap when the engine and radiator are hot can allow steam and scalding liquids to blow out and burn you badly.

Never turn the surge tank pressure cap - even a little - when the engine and radiator are hot.

CAUTION:

You can be burned if you spill coolant on hot engine parts. Coolant contains ethylene glycol, and it will burn if the engine parts are hot enough. Don’t spill coolant on a hot engine.

The vehicle must be on a level surface. When your engine is cold, the coolant level should be at the FILL COLD mark.

When replacing the pressure cap, make sure it is hand tight.

6-33

Coolant Surge Tank Pressure Cap

Your vehicle may be equipped with one of the two caps shown. See “Engine

Compartment Overview” in the Index for more information on location.

The coolant surge tank pressure cap must be fully installed on the coolant surge tank.

NOTICE:

Your coolant surge tank pressure cap is a 15 psi

(105 kPa) pressure type cap and must be tightly installed to prevent coolant loss and possible engine damage from overheating.

When to Check Power Steering Fluid

It is not necessary to regularly check power steering fluid unless you suspect there is a leak in the system or you hear an unusual noise. A fluid loss in this system could indicate a problem. Have the system inspected and repaired. See “Engine Compartment Overview” in the

Index for reservoir location.

How to Check Power Steering Fluid

Turn the key off, let the engine compartment cool down, wipe the cap and the top of the reservoir clean, then unscrew the cap and wipe the dipstick with a clean rag.

Replace the cap and completely tighten it. Then remove the cap again and look at the fluid level on the dipstick.

The level should be at the FULL COLD mark. If necessary, add only enough fluid to bring the level up to the mark.

What to Use

To determine what kind of fluid to use, see

“Recommended Fluids and Lubricants” in the Index.

Always use the proper fluid. Failure to use the proper fluid can cause leaks and damage hoses and seals.

Windshield Washer Fluid

What to Use

When you need windshield washer fluid, be sure to read the manufacturer’s instructions before use. If you will be operating your vehicle in an area where the temperature may fall below freezing, use a fluid that has sufficient protection against freezing. See “Engine Compartment

Overview” in the Index for reservoir location.

Adding Washer Fluid

Open the cap with the washer symbol on it.

Add washer fluid until the tank is full.

6-36

NOTICE:

D When using concentrated washer fluid, follow the manufacturer’s instructions for adding water.

D Don’t mix water with ready to use washer fluid. Water can cause the solution to freeze and damage your washer fluid tank and other parts of the washer system. Also, water doesn’t clean as well as washer fluid.

D Fill your washer fluid tank only three quarters full when it’s very cold. This allows for expansion if freezing occurs, which could damage the tank if it is completely full.

D Don’t use engine coolant (antifreeze) in your windshield washer. It can damage your washer system and paint.

Brakes

Brake Fluid

Your brake master cylinder reservoir is located in the rear of the engine compartment on the driver’s side of the vehicle.

Your brake master cylinder reservoir is filled with

DOT 3 brake fluid. See “Engine Compartment

Overview” in the Index for the location of the reservoir.

There are only two reasons why the brake fluid level in the reservoir might go down. The first is that the brake fluid goes down to an acceptable level during normal brake lining wear. When new linings are put in, the fluid level goes back up. The other reason is that fluid is leaking out of the brake system. If it is, you should have your brake system fixed, since a leak means that sooner or later your brakes won’t work well, or won’t work at all.

6-37

So, it isn’t a good idea to “top off” your brake fluid.

Adding brake fluid won’t correct a leak. If you add fluid when your linings are worn, then you’ll have too much fluid when you get new brake linings. You should add

(or remove) brake fluid, as necessary, only when work is done on the brake hydraulic system.

Checking Brake Fluid

CAUTION:

If you have too much brake fluid, it can spill on the engine. The fluid will burn if the engine is hot enough. You or others could be burned, and your vehicle could be damaged. Add brake fluid only when work is done on the brake hydraulic system. See “Checking Brake Fluid” in this section.

Refer to the Maintenance Schedule to determine when to check your brake fluid. See “Periodic Maintenance

Inspections” in the Index.

You can check the brake fluid without taking off the cap.

Just look at the brake fluid reservoir. The fluid level should be above MIN. If it isn’t, have your brake system checked to see if there is a leak.

After work is done on the brake hydraulic system, make sure the level is above the MIN but not over the

MAX mark.

6-38

What to Add

When you do need brake fluid, use only DOT 3 brake fluid. Refer to “Recommended Fluids and Lubricants” in the Index. Use new brake fluid from a sealed container only.

Always clean the brake fluid reservoir cap and the area around the cap before removing it. This will help keep dirt from entering the reservoir.

CAUTION:

With the wrong kind of fluid in your brake system, your brakes may not work well, or they may not even work at all. This could cause a crash. Always use the proper brake fluid.

NOTICE:

D Using the wrong fluid can badly damage brake system parts. For example, just a few drops of mineral based oil, such as engine oil, in your brake system can damage brake system parts so badly that they’ll have to be replaced. Don’t let someone put in the wrong kind of fluid.

D If you spill brake fluid on your vehicle’s painted surfaces, the paint finish can be damaged. Be careful not to spill brake fluid on your vehicle. If you do, wash it off immediately. See “Appearance Care” in the Index.

6-39

Brake Wear

Your vehicle has four wheel disc brakes.

Disc brake pads have built in wear indicators that make a high pitched warning sound when the brake pads are worn and new pads are needed. The sound may come and go or be heard all the time your vehicle is moving (except when you are pushing on the brake pedal firmly).

CAUTION:

The brake wear warning sound means that soon your brakes won’t work well. That could lead to an accident. When you hear the brake wear warning sound, have your vehicle serviced.

NOTICE:

Continuing to drive with worn out brake pads could result in costly brake repair.

Some driving conditions or climates may cause a brake squeal when the brakes are first applied or lightly applied. This does not mean something is wrong with your brakes.

Properly torqued wheel nuts are necessary to help prevent brake pulsation. When tires are rotated, inspect brake pads for wear and evenly tighten wheel nuts in the proper sequence to GM torque specifications.

Brake linings should always be replaced as complete axle sets.

See “Brake System Inspection” in Section 7 of this manual under Part C “Periodic Maintenance Inspections.”

Brake Pedal Travel

See your dealer if the brake pedal does not return to normal height, or if there is a rapid increase in pedal travel. This could be a sign of brake trouble.

Brake Adjustment

Every time you make a brake stop, your disc brakes adjust for wear.

6-40

Replacing Brake System Parts

The braking system on a vehicle is complex. Its many parts have to be of top quality and work well together if the vehicle is to have really good braking. Your vehicle was designed and tested with top quality GM brake parts. When you replace parts of your braking system - for example, when your brake linings wear down and you need new ones put in - be sure you get new approved GM replacement parts. If you don’t, your brakes may no longer work properly. For example, if someone puts in brake linings that are wrong for your vehicle, the balance between your front and rear brakes can change - for the worse. The braking performance you’ve come to expect can change in many other ways if someone puts in the wrong replacement brake parts.

Battery

Your new vehicle comes with a maintenance free

ACDelco

R

battery. When it’s time for a new battery, get one that has the replacement number shown on the original battery’s label. We recommend an ACDelco battery. See “Engine Compartment Overview” in the

Index for battery location.

WARNING: Battery posts, terminals and related accessories contain lead and lead compounds, chemicals known to the State of California to cause cancer and reproductive harm. Wash hands after handling.

6-41

Vehicle Storage

If you’re not going to drive your vehicle for 25 days or more, remove the black, negative ( ) cable from the battery. This will help keep your battery from running down.

CAUTION:

Batteries have acid that can burn you and gas that can explode. You can be badly hurt if you aren’t careful. See “Jump Starting” in the Index for tips on working around a battery without getting hurt.

Contact your dealer to learn how to prepare your vehicle for longer storage periods.

6-48

Tires

Your new vehicle comes with high quality tires made by a leading tire manufacturer. If you ever have questions about your tire warranty and where to obtain service, see your GM Warranty booklet for details.

CAUTION:

Poorly maintained and improperly used tires are dangerous.

D Overloading your tires can cause overheating as a result of too much friction.

You could have an air out and a serious accident. See “Loading Your Vehicle” in the Index.

CAUTION: (Continued)

CAUTION: (Continued)

D Underinflated tires pose the same danger as overloaded tires. The resulting accident could cause serious injury. Check all tires frequently to maintain the recommended pressure. Tire pressure should be checked when your tires are cold.

D Overinflated tires are more likely to be cut, punctured or broken by a sudden impact - such as when you hit a pothole.

Keep tires at the recommended pressure.

D Worn, old tires can cause accidents. If your tread is badly worn, or if your tires have been damaged, replace them.

6-49

Inflation -- Tire Pressure

The Certification/Tire label, which is on the rear edge of the driver’s door, shows the correct inflation pressures for your tires when they’re cold. “Cold” means your vehicle has been sitting for at least three hours or driven no more than 1 mile (1.6 km).

NOTICE:

Don’t let anyone tell you that underinflation or overinflation is all right. It’s not. If your tires don’t have enough air (underinflation), you can get the following:

D Too much flexing

D Too much heat

D Tire overloading

D Bad wear

D Bad handling

D Bad fuel economy

NOTICE: (Continued)

NOTICE: (Continued)

If your tires have too much air (overinflation), you can get the following:

D Unusual wear

D Bad handling

D Rough ride

D Needless damage from road hazards

When to Check

Check your tires once a month or more. Also, check the tire pressure of the spare tire.

How to Check

Use a good quality pocket type gage to check tire pressure. You can’t tell if your tires are properly inflated simply by looking at them. Radial tires may look properly inflated even when they’re underinflated.

Be sure to put the valve caps back on the valve stems. They help prevent leaks by keeping out dirt and moisture.

6-50

Tire Inspection and Rotation

Tires should be rotated every 6,000 to 8,000 miles

(10 000 to 13 000 km). Any time you notice unusual wear, rotate your tires as soon as possible and check wheel alignment. Also check for damaged tires or wheels.

See “When It’s Time for New Tires” and “Wheel

Replacement” later in this section for more information.

Make sure the spare tire is stored securely. Push, pull, and then try to rotate or turn the tire. If it moves, use the ratchet/wheel wrench to tighten the cable. See “Storing a

Flat or Spare Tire and Tools” in the Index.

The purpose of regular rotation is to achieve more uniform wear for all tires on the vehicle. The first rotation is the most important. See “Scheduled Maintenance

Services” in the Index for scheduled rotation intervals.

When rotating your tires, always use one of the correct rotation patterns shown here.

After the tires have been rotated, adjust the front and rear inflation pressures as shown on the

Certification/Tire label. Make certain that all wheel nuts are properly tightened. See “Wheel Nut Torque” in the Index.

CAUTION:

Rust or dirt on a wheel, or on the parts to which it is fastened, can make wheel nuts become loose after a time. The wheel could come off and cause an accident. When you change a wheel, remove any rust or dirt from places where the wheel attaches to the vehicle. In an emergency, you can use a cloth or a paper towel to do this; but be sure to use a scraper or wire brush later, if you need to, to get all the rust or dirt off. See

“Changing a Flat Tire” in the Index.

6-51

When It’s Time for New Tires

One way to tell when it’s time for new tires is to check the treadwear indicators, which will appear when your tires have only 1/16 inch (1.6 mm) or less of tread remaining.

You need a new tire if any of the following statements are true:

D You can see the indicators at three or more places around the tire.

D You can see cord or fabric showing through the tire’s rubber.

D The tread or sidewall is cracked, cut or snagged deep enough to show cord or fabric.

D The tire has a bump, bulge or split.

D The tire has a puncture, cut or other damage that can’t be repaired well because of the size or location of the damage.

Buying New Tires

To find out what kind and size of tires you need, look at the Certification/Tire label.

The tires installed on your vehicle when it was new had a Tire Performance Criteria Specification (TPC Spec) number on each tire’s sidewall. When you get new tires, get ones with that same TPC Spec number. That way your vehicle will continue to have tires that are designed to give proper endurance, handling, speed rating, traction, ride and other things during normal service on your vehicle. If your tires have an all season tread design, the TPC number will be followed by an “MS”

(for mud and snow).

6-52

If you ever replace your tires with those not having a

TPC Spec number, make sure they are the same size, load range, speed rating and construction type

(bias, bias belted or radial) as your original tires.

CAUTION:

Mixing tires could cause you to lose control while driving. If you mix tires of different sizes or types

(radial and bias belted tires), the vehicle may not handle properly, and you could have a crash.

Using tires of different sizes may also cause damage to your vehicle. Be sure to use the same size and type tires on all wheels.

CAUTION: (Continued)

CAUTION: (Continued)

If your vehicle has 17 inch road tires (those originally installed on your vehicle) it is all right to drive with the 16 inch spare tire that came with your vehicle. When new, your vehicle included a spare tire and wheel assembly with the same overall diameter as your vehicle’s road tires and wheels. Because this spare tire was developed for use on your vehicle, it will not affect vehicle handling or cause damage to your vehicle.

CAUTION:

If you use bias ply tires on your vehicle, the wheel rim flanges could develop cracks after many miles of driving. A tire and/or wheel could fail suddenly, causing a crash. Use only radial ply tires with the wheels on your vehicle.

6-53

Uniform Tire Quality Grading

Quality grades can be found where applicable on the tire sidewall between tread shoulder and maximum section width. For example:

Treadwear 200 Traction AA Temperature A

The following information relates to the system developed by the United States National Highway

Traffic Safety Administration, which grades tires by treadwear, traction and temperature performance.

(This applies only to vehicles sold in the United States.)

The grades are molded on the sidewalls of most passenger car tires. The Uniform Tire Quality Grading system does not apply to deep tread, winter type snow tires, space saver or temporary use spare tires, tires with nominal rim diameters of 10 to 12 inches (25 to 30 cm), or to some limited production tires.

While the tires available on General Motors passenger cars and light trucks may vary with respect to these grades, they must also conform to federal safety requirements and additional General Motors Tire

Performance Criteria (TPC) standards.

Treadwear

The treadwear grade is a comparative rating based on the wear rate of the tire when tested under controlled conditions on a specified government test course.

For example, a tire graded 150 would wear one and a half (1 1/2) times as well on the government course as a tire graded 100. The relative performance of tires depends upon the actual conditions of their use, however, and may depart significantly from the norm due to variations in driving habits, service practices and differences in road characteristics and climate.

Traction

--

AA, A, B, C

The traction grades, from highest to lowest, are AA,

A, B, and C. Those grades represent the tire’s ability to stop on wet pavement as measured under controlled conditions on specified government test surfaces of asphalt and concrete. A tire marked C may have poor traction performance. Warning: The traction grade assigned to this tire is based on straight ahead braking traction tests, and does not include acceleration, cornering, hydroplaning, or peak traction characteristics.

6-54

Temperature

--

A, B, C

The temperature grades are A (the highest), B, and C, representing the tire’s resistance to the generation of heat and its ability to dissipate heat when tested under controlled conditions on a specified indoor laboratory test wheel. Sustained high temperature can cause the material of the tire to degenerate and reduce tire life, and excessive temperature can lead to sudden tire failure.

The grade C corresponds to a level of performance which all passenger car tires must meet under the

Federal Motor Vehicle Safety Standard No. 109.

Grades B and A represent higher levels of performance on the laboratory test wheel than the minimum required by law.

Warning: The temperature grade for this tire is established for a tire that is properly inflated and not overloaded. Excessive speed, underinflation, or excessive loading, either separately or in combination, can cause heat buildup and possible tire failure.

Wheel Alignment and Tire Balance

The wheels on your vehicle were aligned and balanced carefully at the factory to give you the longest tire life and best overall performance.

Scheduled wheel alignment and wheel balancing are not needed. However, if you notice unusual tire wear or your vehicle pulling one way or the other, the alignment may need to be reset. If you notice your vehicle vibrating when driving on a smooth road, your wheels may need to be rebalanced.

6-55

Wheel Replacement

Replace any wheel that is bent, cracked, or badly rusted or corroded. If wheel nuts keep coming loose, the wheel, wheel bolts and wheel nuts should be replaced. If the wheel leaks air, replace it (except some aluminum wheels, which can sometimes be repaired). See your dealer if any of these conditions exist.

Your dealer will know the kind of wheel you need.

Each new wheel should have the same load carrying capacity, diameter, width, offset and be mounted the same way as the one it replaces.

If you need to replace any of your wheels, wheel bolts or wheel nuts, replace them only with new GM original equipment parts. This way, you will be sure to have the right wheel, wheel bolts and wheel nuts for your vehicle.

CAUTION:

Using the wrong replacement wheels, wheel bolts or wheel nuts on your vehicle can be dangerous.

It could affect the braking and handling of your vehicle, make your tires lose air and make you lose control. You could have a collision in which you or others could be injured. Always use the correct wheel, wheel bolts and wheel nuts for replacement.

6-56

NOTICE:

The wrong wheel can also cause problems with bearing life, brake cooling, speedometer or odometer calibration, headlamp aim, bumper height, vehicle ground clearance and tire or tire chain clearance to the body and chassis.

See “Changing a Flat Tire” in the Index for more information.

Used Replacement Wheels

CAUTION:

Putting a used wheel on your vehicle is dangerous. You can’t know how it’s been used or how far it’s been driven. It could fail suddenly and cause a crash. If you have to replace a wheel, use a new GM original equipment wheel.

6-57

Tire Chains

CAUTION:

If your vehicle has P265/75R16, LT265/75R16 or

P265/70R16 size tires, don’t use tire chains. They can damage your vehicle because there’s not enough clearance. Tire chains used on a vehicle without the proper amount of clearance can cause damage to the brakes, suspension or other vehicle parts. The area damaged by the tire chains could cause you to lose control of your vehicle and you or others may be injured in a crash.

CAUTION: (Continued)

CAUTION: (Continued)

Use another type of traction device only if its manufacturer recommends it for use on your vehicle and tire size combination and road conditions. Follow that manufacturer’s instructions. To help avoid damage to your vehicle, drive slowly, readjust or remove the device if it’s contacting your vehicle, and don’t spin your wheels.

If you do find traction devices that will fit, install them on the rear tires.

6-58

NOTICE:

If you have a tire size other than P265/75R16,

LT265/75R16 or P265/70R16, use tire chains only where legal and only when you must. Use chains that are the proper size for your tires. Install them on the tires of the rear axle.

Don’t use chains on the tires of the front axle.

Tighten them as tightly as possible with the ends securely fastened. Drive slowly and follow the chain manufacturer’s instructions. If you can hear the chains contacting your vehicle, stop and retighten them. If the contact continues, slow down until it stops. Driving too fast or spinning the wheels with chains on will damage your vehicle.

Appearance Care

Remember, cleaning products can be hazardous. Some are toxic. Others can burst into flame if you strike a match or get them on a hot part of the vehicle. Some are dangerous if you breathe their fumes in a closed space.

When you use anything from a container to clean your vehicle, be sure to follow the manufacturer’s warnings and instructions. And always open your doors or windows when you’re cleaning the inside.

Never use these to clean your vehicle:

D Gasoline

D Benzene

D Naphtha

D Carbon Tetrachloride

D Acetone

D Paint Thinner

D Turpentine

D Lacquer Thinner

D Nail Polish Remover

They can all be hazardous - some more than others - and they can all damage your vehicle, too.

6-59

Don’t use any of these unless this manual says you can.

In many uses, these will damage your vehicle:

D Alcohol

D Laundry Soap

D Bleach

D Reducing Agents

Cleaning the Inside of Your Vehicle

Use a vacuum cleaner often to get rid of dust and loose dirt. Wipe vinyl, leather, plastic and painted surfaces with a clean, damp cloth.

Cleaning of Fabric/Carpet

Your dealer has cleaners for the cleaning of fabric and carpet. They will clean normal spots and stains very well. You can get GM approved cleaning products from your dealer. See “Appearance Care and Materials” in the Index.

Here are some cleaning tips:

D Always read the instructions on the cleaner label.

D Clean up stains as soon as you can - before they set.

D Carefully scrape off any excess stain.

D Use a clean cloth or sponge, and change to a clean area often. A soft brush may be used if stains are stubborn.

D If a ring forms on fabric after spot cleaning, clean the entire area immediately or it will set.

Using Cleaner on Fabric

1. Vacuum and brush the area to remove any loose dirt.

2. Always clean a whole trim panel or section. Mask surrounding trim along stitch or welt lines.

3. Follow the directions on the container label.

4. Apply cleaner with a clean sponge. Don’t saturate the material and don’t rub it roughly.

5. As soon as you’ve cleaned the section, use a sponge to remove any excess cleaner.

6. Wipe cleaned area with a clean, water dampened towel or cloth.

7. Wipe with a clean cloth and let dry.

6-60

Special Fabric Cleaning Problems

Stains caused by such things as catsup, coffee (black), egg, fruit, fruit juice, milk, soft drinks, vomit, urine and blood can be removed as follows:

1. Carefully scrape off excess stain, then sponge the soiled area with cool water.

2. If a stain remains, follow the cleaner instructions described earlier.

3. If an odor lingers after cleaning vomit or urine, treat the area with a water/baking soda solution:

1 teaspoon (5 ml) of baking soda to 1 cup (250 ml) of lukewarm water.

4. Let dry.

Stains caused by candy, ice cream, mayonnaise, chili sauce and unknown stains can be removed as follows:

1. Carefully scrape off excess stain.

2. First, clean with cool water and allow to dry completely.

3. If a stain remains, follow the cleaner instructions described earlier.

Cleaning Vinyl

Use warm water and a clean cloth.

D Rub with a clean, damp cloth to remove dirt.

You may have to do it more than once.

D Things like tar, asphalt and shoe polish will stain if you don’t get them off quickly. Use a clean cloth and a vinyl/leather cleaner. See your dealer for this product.

Cleaning Leather

Use a soft cloth with lukewarm water and a mild soap or saddle soap and wipe dry with a soft cloth. Then, let the leather dry naturally. Do not use heat to dry.

D For stubborn stains, use a leather cleaner. See your dealer for this product.

D Never use oils, varnishes, solvent based or abrasive cleaners, furniture polish or shoe polish on leather.

D Soiled or stained leather should be cleaned immediately. If dirt is allowed to work into the finish, it can harm the leather.

6-61

Cleaning the Top of the Instrument Panel

Use only mild soap and water to clean the top surfaces of the instrument panel. Sprays containing silicones or waxes may cause annoying reflections in the windshield and even make it difficult to see through the windshield under certain conditions.

Cleaning Interior Plastic Components

Use only a mild soap and water solution on a soft cloth or sponge. Commercial cleaners may affect the surface finish.

Care of Safety Belts

Keep belts clean and dry.

Cleaning Glass Surfaces

Glass should be cleaned often. GM Glass Cleaner or a liquid household glass cleaner will remove normal tobacco smoke and dust films on interior glass. See

“Appearance Care and Materials” in the Index.

NOTICE:

Don’t use abrasive cleaners on glass, because they may cause scratches. Avoid placing decals on the inside rear window, since they may have to be scraped off later. If abrasive cleaners are used on the inside of the rear window, an electric defogger element may be damaged. Any temporary license should not be attached across the defogger grid.

CAUTION:

Do not bleach or dye safety belts. If you do, it may severely weaken them. In a crash, they might not be able to provide adequate protection.

Clean safety belts only with mild soap and lukewarm water.

6-62

Cleaning the Outside of the

Windshield, Backglass and

Wiper Blades

If the windshield is not clear after using the windshield washer, or if the wiper blade chatters when running, wax, sap or other material may be on the blade or windshield.

Clean the outside of the windshield with a full strength glass cleaning liquid. The windshield is clean if beads do not form when you rinse it with water.

Grime from the windshield will stick to the wiper blades and affect their performance. Clean the blade by wiping vigorously with a cloth soaked in full strength windshield washer solvent. Then rinse the blade with water.

Check the wiper blades and clean them as necessary; replace blades that look worn.

Weatherstrips

Silicone grease on weatherstrips will make them last longer, seal better, and not stick or squeak. Apply silicone grease with a clean cloth at least every six months. During very cold, damp weather more frequent application may be required. See

“Recommended Fluids and Lubricants” in the Index.

Cleaning the Outside of Your Vehicle

The paint finish on your vehicle provides beauty, depth of color, gloss retention and durability.

Washing Your Vehicle

The best way to preserve your vehicle’s finish is to keep it clean by washing it often with lukewarm or cold water.

Don’t wash your vehicle in the direct rays of the sun.

Use a car washing soap. Don’t use strong soaps or chemical detergents. Be sure to rinse the vehicle well, removing all soap residue completely. You can get

GM approved cleaning products from your dealer. See

“Appearance Care and Materials” in the Index. Don’t use cleaning agents that are petroleum based, or that contain acid or abrasives. All cleaning agents should be flushed promptly and not allowed to dry on the surface, or they could stain. Dry the finish with a soft, clean chamois or an all cotton towel to avoid surface scratches and water spotting.

High pressure car washes may cause water to enter your vehicle.

6-63

Cleaning Exterior Lamps/Lenses

Use only lukewarm or cold water, a soft cloth and a car washing soap to clean exterior lamps and lenses. Follow instructions under “Washing Your Vehicle.”

Finish Care

Occasional waxing or mild polishing of your vehicle by hand may be necessary to remove residue from the paint finish. You can get GM approved cleaning products from your dealer. See “Appearance Care and Materials” in the Index.

Your vehicle has a “basecoat/clearcoat” paint finish.

The clearcoat gives more depth and gloss to the colored basecoat. Always use waxes and polishes that are non abrasive and made for a basecoat/clearcoat paint finish.

NOTICE:

Machine compounding or aggressive polishing on a basecoat/clearcoat paint finish may dull the finish or leave swirl marks.

Foreign materials such as calcium chloride and other salts, ice melting agents, road oil and tar, tree sap, bird droppings, chemicals from industrial chimneys, etc., can damage your vehicle’s finish if they remain on painted surfaces. Wash the vehicle as soon as possible. If necessary, use non abrasive cleaners that are marked safe for painted surfaces to remove foreign matter.

Exterior painted surfaces are subject to aging, weather and chemical fallout that can take their toll over a period of years. You can help to keep the paint finish looking new by keeping your vehicle garaged or covered whenever possible.

6-64

Protecting Exterior Bright Metal Parts

Bright metal parts should be cleaned regularly to keep their luster. Washing with water is all that is usually needed. However, you may use chrome polish on chrome or stainless steel trim, if necessary.

Use special care with aluminum trim. To avoid damaging protective trim, never use auto or chrome polish, steam or caustic soap to clean aluminum. A coating of wax, rubbed to high polish, is recommended for all bright metal parts.

Cleaning Aluminum or

Chrome

-

Plated Wheels (If Equipped)

Keep your wheels clean using a soft clean cloth with mild soap and water. Rinse with clean water. After rinsing thoroughly, dry with a soft clean towel. A wax may then be applied.

The surface of these wheels is similar to the painted surface of your vehicle. Don’t use strong soaps, chemicals, abrasive polishes, abrasive cleaners, cleaners with acid or abrasive cleaning brushes on them because you could damage the surface. Do not use chrome polish on aluminum wheels.

Use chrome polish only on chrome plated wheels, but avoid any painted surface of the wheel, and buff off immediately after application.

Don’t take your vehicle through an automatic car wash that has silicon carbide tire cleaning brushes. These brushes can also damage the surface of these wheels.

Cleaning Tires

To clean your tires, use a stiff brush with a tire cleaner.

NOTICE:

When applying a tire dressing always take care to wipe off any overspray or splash from all painted surfaces on the body or wheels of the vehicle.

Petroleum based products may damage the paint finish and tires.

6-65

Sheet Metal Damage

If your vehicle is damaged and requires sheet metal repair or replacement, make sure the body repair shop applies anti corrosion material to the parts repaired or replaced to restore corrosion protection.

Original manufacturer replacement parts will provide the corrosion protection while maintaining the warranty.

Finish Damage

Any stone chips, fractures or deep scratches in the finish should be repaired right away. Bare metal will corrode quickly and may develop into a major repair expense.

Minor chips and scratches can be repaired with touch up materials available from your dealer or other service outlets. Larger areas of finish damage can be corrected in your dealer’s body and paint shop.

Underbody Maintenance

Chemicals used for ice and snow removal and dust control can collect on the underbody. If these are not removed, accelerated corrosion (rust) can occur on the underbody parts such as fuel lines, frame, floor pan and exhaust system even though they have corrosion protection.

At least every spring, flush these materials from the underbody with plain water. Clean any areas where mud and other debris can collect. Dirt packed in closed areas of the frame should be loosened before being flushed.

Your dealer or an underbody car washing system can do this for you.

Chemical Paint Spotting

Some weather and atmospheric conditions can create a chemical fallout. Airborne pollutants can fall upon and attack painted surfaces on your vehicle. This damage can take two forms: blotchy, ringlet shaped discolorations, and small irregular dark spots etched into the paint surface.

Although no defect in the paint job causes this, GM will repair, at no charge to the owner, the surfaces of new vehicles damaged by this fallout condition within

12 months or 12,000 miles (20 000 km) of purchase, whichever occurs first.

This applies only to materials manufactured and sold by

General Motors. Bodies, body conversions or equipment not made or sold by General Motors are not covered.

GM Vehicle Care/Appearance Materials

6-67

Vehicle Identification Number (VIN)

This is the legal identifier for your vehicle. It appears on a plate in the front corner of the instrument panel, on the driver’s side. You can see it if you look through the windshield from outside your vehicle. The VIN also appears on the Vehicle Certification and Service Parts labels and the certificates of title and registration.

Engine Identification

The 8th character in your VIN is the engine code. This code will help you identify your engine, specifications and replacement parts.

Service Parts Identification Label

You’ll find this label located in the glove box. It’s very helpful if you ever need to order parts. On this label is:

D your VIN,

D the model designation,

D paint information and

D a list of all production options and special equipment.

Be sure that this label is not removed from the vehicle.

6-68

Electrical System

Add-On Electrical Equipment

NOTICE:

Don’t add anything electrical to your vehicle unless you check with your dealer first. Some electrical equipment can damage your vehicle and the damage wouldn’t be covered by your warranty. Some add on electrical equipment can keep other components from working as they should.

Your vehicle has an air bag system. Before attempting to add anything electrical to your vehicle, see “Servicing

Your Air Bag Equipped Vehicle” in the Index.

Windshield Wipers

The windshield wiper motor is protected by an internal circuit breaker and a fuse. If the motor overheats due to heavy snow, etc., the wiper will stop until the motor cools. If the overload is caused by some electrical problem and not snow, etc., be sure to get it fixed.

Power Windows and Other Power Options

Circuit breakers protect the power windows and other power accessories. When the current load is too heavy, the circuit breaker opens and closes, protecting the circuit until the problem is fixed or goes away.

Fuses and Circuit Breakers

The wiring circuits in your vehicle are protected from short circuits by a combination of fuses, circuit breakers and fusible thermal links. This greatly reduces the chance of fires caused by electrical problems.

Look at the silver colored band inside the fuse. If the band is broken or melted, replace the fuse. Be sure you replace a bad fuse with a new one of the identical size and rating.

If you ever have a problem on the road and don’t have a spare fuse, you can borrow one that has the same amperage. Just pick some feature of your vehicle that you can get along without lighter

- like the radio or cigarette

- and use its fuse, if it is the correct amperage.

Replace it as soon as you can.

6-69

Instrument Panel Fuse Block

The fuse block access door is on the driver’s side edge of the instrument panel. Pull off the cover to access the fuse block.

You can remove fuses with a fuse extractor which is mounted to the fuse block access door. To remove fuses if you don’t have a fuse extractor, hold the end of the fuse between your thumb and index finger and pull straight out.

You may have spare fuses located behind the fuse block access door. These can be used to replace a bad fuse.

However, make sure it is of the correct amperage.

Have you purchased the GM Protection Plan? The Plan supplements your new vehicle warranties. See your

Warranty and Owner Assistance booklet or your dealer

for details.

Introduction

Your Vehicle and the Environment

Proper vehicle maintenance not only helps to keep your vehicle in good working condition, but also helps the environment. All recommended maintenance procedures are important. Improper vehicle maintenance can even affect the quality of the air we breathe. Improper fluid levels or the wrong tire inflation can increase the level of emissions from your vehicle. To help protect our environment, and to keep your vehicle in good condition, please maintain your vehicle properly.

Maintenance Requirements

Maintenance intervals, checks, inspections and recommended fluids and lubricants as prescribed in this manual are necessary to keep your vehicle in good working condition. Any damage caused by failure to follow recommended maintenance may not be covered by warranty.

7-2

How This Section is Organized

This maintenance schedule is divided into five parts:

“Part A: Scheduled Maintenance Services” explains what to have done and how often. Some of these services can be complex, so unless you are technically qualified and have the necessary equipment, you should let your dealer’s service department or another qualified service center do these jobs.

CAUTION:

Performing maintenance work on a vehicle can be dangerous. In trying to do some jobs, you can be seriously injured. Do your own maintenance work only if you have the required know how and the proper tools and equipment for the job.

If you have any doubt, have a qualified technician do the work.

“Part B: Owner Checks and Services” tells you what should be checked and when. It also explains what you can easily do to help keep your vehicle in good condition.

“Part C: Periodic Maintenance Inspections” explains important inspections that your dealer’s service department or another qualified service center should perform.

“Part D: Recommended Fluids and Lubricants” lists some recommended products necessary to help keep your vehicle properly maintained. These products, or their equivalents, should be used whether you do the work yourself or have it done.

“Part E: Maintenance Record” is a place for you to record and keep track of the maintenance performed on your vehicle. Keep your maintenance receipts. They may be needed to qualify your vehicle for warranty repairs.

If you want to get the service information, see “Service and Owner Publications” in the Index.

Part A: Scheduled

Maintenance Services

Using Your Maintenance Schedule

We at General Motors want to help you keep your vehicle in good working condition. But we don’t know exactly how you’ll drive it. You may drive very short distances only a few times a week. Or you may drive long distances all the time in very hot, dusty weather.

You may use your vehicle in making deliveries.

Or you may drive it to work, to do errands or in many other ways.

Because of all the different ways people use their vehicles, maintenance needs vary. You may need more frequent checks and replacements. So please read the following and note how you drive. If you have any questions on how to keep your vehicle in good condition, see your dealer.

This part tells you the maintenance services you should have done and when you should schedule them. If you go to your dealer for your service needs, you’ll know that GM trained and supported service people will perform the work using genuine GM parts.

The proper fluids and lubricants to use are listed in

Part D. Make sure whoever services your vehicle uses these. All parts should be replaced and all necessary repairs done before you or anyone else drives the vehicle.

This schedule is for vehicles that:

D carry passengers and cargo within recommended limits. You will find these limits on your vehicle’s

Certification/Tire label. See “Loading Your Vehicle” in the Index.

D are driven on reasonable road surfaces within legal driving limits.

D are driven off

See “Off

road in the recommended manner.

Road Driving With Your

Four Wheel Drive Vehicle” in the Index.

D use the recommended fuel. See “Fuel” in the Index.

Footnotes

[ The U.S. Environmental Protection Agency or the

California Air Resources Board has determined that the failure to perform this maintenance item will not nullify the emission warranty or limit recall liability prior to the completion of the vehicle’s useful life. We, however, urge that all recommended maintenance services be performed at the indicated intervals and the maintenance be recorded.

+ A good time to check your brakes is during tire rotation. See “Brake System Inspection” under

“Periodic Maintenance Inspections” in Part C of this schedule.

7-5

Scheduled Maintenance

Engine Oil and Chassis Lubrication

Scheduled Maintenance

Change engine oil and filter as indicated by the

GM Oil Life System t (or every 12 months, whichever occurs first). Reset the system.

Your vehicle has a computer system that lets you know when to change the engine oil and filter. This is based on engine revolutions and engine temperature, and not on mileage. Based on driving conditions, the mileage at which an oil change will be indicated can vary considerably. For the oil life system to work properly, you must reset the system every time the oil is changed.

When the system has calculated that oil life has been diminished, it will indicate that an oil change is necessary. A CHANGE ENGINE OIL message will come on. Change your oil as soon as possible within the next two times you stop for fuel. It is possible that, if you are driving under the best conditions, the oil life system may not indicate that an oil change is necessary for over a year. However, your engine oil and filter must be changed at least once a year and at this time the system must be reset. It is also important to check your oil regularly and keep it at the proper level.

If the system is ever reset accidentally, you must change your oil at 3,000 miles (5 000 km) since your last oil change. Remember to reset the oil life system whenever the oil is changed. See “Oil Life System” in the Index for information on resetting the system.

An Emission Control Service.

Lubricate chassis components with each engine oil and

filter change. Lubricate the front suspension, ball joints, steering linkage, transmission shift linkage, transfer case shift linkage, and parking brake cable guides. Ball joints should not be lubricated unless their temperature is

10

_F ( 12

_C) or higher, or they could be damaged.

At Least Twice a Year

Restraint System Check

Make sure the safety belt reminder light and all your belts, buckles, latch plates, retractors and anchorages are working properly. Look for any other loose or damaged safety belt system parts. If you see anything that might keep a safety belt system from doing its job, have it repaired. Have any torn or frayed safety belts replaced.

Also look for any opened or broken air bag coverings, and have them repaired or replaced. (The air bag system does not need regular maintenance.)

Wiper Blade Check

Inspect wiper blades for wear or cracking. Replace blade inserts that appear worn or damaged or that streak or miss areas of the windshield. Also see “Wiper Blades,

Cleaning” in the Index.

Spare Tire Check

At least twice a year, after the monthly inflation check of the spare tire determines that the spare is inflated to the correct tire inflation pressure, make sure that the spare tire is stored securely. Push, pull, and then try to rotate or turn the tire. If it moves, use the wheel wrench/ratchet to tighten the cable. See “Storing the

Spare Tire and Tools” in the Index.

Engine Air Cleaner Filter Restriction

Indicator Check

Your vehicle has an indicator located on the air cleaner in the engine compartment that lets you know when the air cleaner filter is dirty and needs to be changed. Check indicator at least twice a year or when your engine oil is changed, whichever occurs first. See “Air Cleaner” in the Index for more information. Inspect your air cleaner filter restriction indicator more often if the vehicle is used in dusty areas or under off road conditions.

7-18

Weatherstrip Lubrication

Silicone grease on weatherstrips will make them last longer, seal better, and not stick or squeak. Apply silicone grease with a clean cloth. During very cold, damp weather more frequent application may be required. See “Recommended Fluids and Lubricants” in the Index.

Automatic Transmission Check

Check the transmission fluid level; add if needed. See

“Automatic Transmission Fluid” in the Index. A fluid loss may indicate a problem. Check the system and repair if needed.

CAUTION:

When you are doing this check, your vehicle could begin to move. You or others could be injured and property could be damaged. Make sure there is room in front of your vehicle in case it begins to roll. Be ready to apply the regular brake at once should the vehicle begin to move.

Park on a fairly steep hill, with the vehicle facing downhill. Keeping your foot on the regular brake, set the parking brake.

D To check the parking brake’s holding ability: With the engine running and transmission in

NEUTRAL (N), slowly remove foot pressure from the regular brake pedal. Do this until the vehicle is held by the parking brake only.

D To check the PARK (P) mechanism’s holding ability: With the engine running, shift to PARK (P).

Then release the parking brake followed by the regular brake.

Underbody Flushing Service

At least every spring, use plain water to flush any corrosive materials from the underbody. Take care to clean thoroughly any areas where mud and other debris can collect.

7-21

Part C: Periodic

Maintenance Inspections

Listed in this part are inspections and services which should be performed at least twice a year (for instance, each spring and fall). You should let your dealer’s service department or other qualified service center do these jobs. Make sure any necessary repairs are completed at once.

Proper procedures to perform these services may be found in a service manual. See “Service and Owner

Publications” in the Index.

Steering and Suspension Inspection

Inspect the front and rear suspension and steering system for damaged, loose or missing parts, signs of wear or lack of lubrication. Inspect the power steering lines and hoses for proper hook up, binding, leaks, cracks, chafing, etc.

Exhaust System Inspection

Inspect the complete exhaust system. Inspect the body near the exhaust system. Look for broken, damaged, missing or out of position parts as well as open seams, holes, loose connections or other conditions which could cause a heat build up in the floor pan or could let exhaust fumes into the vehicle. See “Engine Exhaust” in the Index.

7-22

Fuel System Inspection

Inspect the complete fuel system for damage or leaks.

Engine Cooling System Inspection

Inspect the hoses and have them replaced if they are cracked, swollen or deteriorated. Inspect all pipes, fittings and clamps; replace as needed. Clean the outside of the radiator and air conditioning condenser. To help ensure proper operation, a pressure test of the cooling system and pressure cap is recommended at least once a year.

Throttle System Inspection

Inspect the throttle system for interference or binding, and for damaged or missing parts. Replace parts as needed. Replace any components that have high effort or excessive wear. Do not lubricate accelerator and cruise control cables.

Transfer Case and Front Axle

(Four-Wheel Drive) Inspection

Every 12 months or at engine oil change intervals, check front axle and transfer case and add lubricant when necessary. A fluid loss could indicate a problem; check and have it repaired, if needed. On manual shift transfer case, oil the control lever pivot point. Check vent hose at transfer case for kinks and proper installation. More frequent lubrication may be required on off road use.

Brake System Inspection

Inspect the complete system. Inspect brake lines and hoses for proper hook up, binding, leaks, cracks, chafing, etc. Inspect disc brake pads for wear and rotors for surface condition. Inspect other brake parts, including calipers, parking brake, etc. You may need to have your brakes inspected more often if your driving habits or conditions result in frequent braking.

Customer Satisfaction Procedure

Your satisfaction and goodwill are important to your dealer and to Chevrolet. Normally, any concerns with the sales transaction or the operation of your vehicle will be resolved by your dealer’s sales or service departments. Sometimes, however, despite the best intentions of all concerned, misunderstandings can occur. If your concern has not been resolved to your satisfaction, the following steps should be taken:

STEP ONE -- Discuss your concern with a member of dealership management. Normally, concerns can be quickly resolved at that level. If the matter has already been reviewed with the sales, service or parts manager, contact the owner of the dealership or the general manager.

8-2

STEP TWO -- If after contacting a member of dealership management, it appears your concern cannot be resolved by the dealership without further help, contact the Chevrolet Customer Assistance Center by calling 1-800-222-1020. In Canada, contact GM of Canada

Customer Communication Centre in Oshawa by calling

1-800-263-3777 (English) or 1-800-263-7854 (French).

We encourage you to call the toll-free number in order to give your inquiry prompt attention. Please have the following information available to give the Customer

Assistance Representative:

D Vehicle Identification Number (This is available from the vehicle registration or title, or the plate at the top left of the instrument panel and visible through the windshield.)

D Dealership name and location

D Vehicle delivery date and present mileage

When contacting Chevrolet, please remember that your concern will likely be resolved at a dealer’s facility.

That is why we suggest you follow Step One first if you have a concern.

STEP THREE -- Both General Motors and your dealer are committed to making sure you are completely satisfied with your new vehicle. However, if you continue to remain unsatisfied after following the procedure outlined in Steps One and Two, you should file with the GM/BBB Auto Line Program to enforce any additional rights you may have. Canadian owners refer to your Warranty and Owner Assistance

Information booklet for information on the Canadian

Motor Vehicle Arbitration Plan (CAMVAP).

The BBB Auto Line Program is an out of court program administered by the Council of Better Business Bureaus to settle automotive disputes regarding vehicle repairs or the interpretation of the New Vehicle Limited Warranty.

Although you may be required to resort to this informal dispute resolution program prior to filing a court action, use of the program is free of charge and your case will generally be heard within 40 days. If you do not agree with the decision given in your case, you may reject it and proceed with any other venue for relief available to you.

8-3

You may contact the BBB using the toll free telephone number or write them at the following address:

Canadian Roadside Assistance

Vehicles purchased in Canada have an extensive

Roadside Assistance program accessible from anywhere in Canada or the United States. Please refer to the

Warranty and Owner Assistance Information book or call 1 800 268 6800 for emergency services.

Courtesy Transportation

Chevrolet has always exemplified quality and value in its offering of motor vehicles. To enhance your ownership experience, we and our participating dealers are proud to offer Courtesy Transportation, a customer support program for new vehicles.

The Courtesy Transportation program is offered to retail purchase/lease customers in conjunction with the Bumper to Bumper coverage provided by the

New Vehicle Limited Warranty. Several transportation options are available when warranty repairs are required. This will reduce your inconvenience during warranty repairs.

Plan Ahead When Possible

When your vehicle requires warranty service, you should contact your dealer and request an appointment.

By scheduling a service appointment and advising your service consultant of your transportation needs, your dealer can help minimize your inconvenience. If your vehicle cannot be scheduled into the service department immediately, keep driving it until it can be scheduled for service, unless, of course, the problem is safety related.

If it is, please call your dealership, let them know this, and ask for instructions.

8-8

If the dealer requests that you simply drop the vehicle off for service, you are urged to do so as early in the work day as possible to allow for same day repair.

Transportation Options

Warranty service can generally be completed while you wait. However, if you are unable to wait Chevrolet helps minimize your inconvenience by providing several transportation options. Depending on the circumstances, your dealer can offer you one of the following:

Shuttle Service

Participating dealers can provide you with shuttle service to get you to your destination with minimal interruption of your daily schedule. This includes a one way shuttle ride to a destination up to 10 miles from the dealership.

Public Transportation or Fuel Reimbursement

If your vehicle requires overnight warranty repairs, reimbursement up to $30 per day (five days maximum) may be available for the use of public transportation such as taxi or bus. In addition, should you arrange transportation through a friend or relative, reimbursement for reasonable fuel expenses up to

$10 per day (five day maximum) may be available.

Claim amounts should reflect actual costs and be supported by original receipts.

Courtesy Rental Vehicle

When your vehicle is unavailable due to overnight warranty repairs, your dealer may arrange to provide you with a courtesy rental vehicle or reimburse you for a rental vehicle you obtained, at actual cost, up to a maximum of $30.00 per day supported by receipts.

This requires that you sign and complete a rental agreement and meet state, local and rental vehicle provider requirements. Requirements vary and may include minimum age requirements, insurance coverage, credit card, etc. You are responsible for fuel usage charges and may also be responsible for taxes, levies, usage fees, excessive mileage or rental usage beyond the completion of the repair.

Generally it is not possible to provide a like vehicle as a courtesy rental.

Additional Program Information

Courtesy Transportation is available during the

Bumper to Bumper warranty coverage period, but it is not part of the New Vehicle Limited Warranty.

A separate booklet entitled “Warranty and Owner

Assistance Information” furnished with each new vehicle provides detailed warranty coverage information.

8-9

Courtesy Transportation is available only at participating dealers and all program options, such as shuttle service, may not be available at every dealer.

Please contact your dealer for specific information about availability. All Courtesy Transportation arrangements will be administered by appropriate dealer personnel.

Canadian Vehicles: For warranty repairs during the

Complete Vehicle Coverage period of the General

Motors of Canada New Vehicle Limited Warranty, alternative transportation may be available under the

Courtesy Transportation Program. Please consult your dealer for details.

General Motors reserves the right to unilaterally modify, change or discontinue Courtesy Transportation at any time and to resolve all questions of claim eligibility pursuant to the terms and conditions described herein at its sole discretion.

Warranty Information

Your vehicle comes with a separate warranty booklet that contains detailed warranty information.

REPORTING SAFETY

DEFECTS TO THE UNITED
