How to Use this Manual
Safety Warnings and Symbols
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.
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.
vii
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.”
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 Damage Warnings
Also, in this book you will find these notices:
NOTICE:
These mean there is something that could
damage your vehicle.

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 split bench seat,
you can adjust it with this lever located at the front of
the seat.
Lift the lever at the front of the seat to unlock it. Using
your body, slide the seat to where you want it. Then,
release the lever and try to move the seat with your body
in order 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,
you can increase or
decrease lumbar support
in an area of the lower
seatback. The control is
located on the outboard
side of the front seats.
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 support, turn the knob towards the front of
the vehicle. Operating effort can be reduced if you lean
forward slightly while turning the knob.
To decrease support, turn the knob towards the rear of
the vehicle.
1-3
Power Seat(s) (If Equipped)
Raise or lower the front of the seat cushion by raising or
lowering the forward edge of the button.
Move the seat forward or rearward by moving the whole
button forward or rearward.
Raise or lower the rear of the seat cushion by raising or
lowering the rear edge of the button.
Moving the whole button up or down raises or lowers
the entire seat cushion.
Vertical Control: If your vehicle has the power
reclining seats, you can use this button to adjust the
angle of the seatback. Move the reclining front seatback
rearward or forward by moving this button toward the
rear or the front of the vehicle. See “Reclining
Seatbacks” in the Index for further information.
Horizontal Control: If your vehicle has a power seat,
you can adjust it with these controls located at the
outboard edges of the seats.
1-4
Power Lumbar Control (If Equipped)
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.
Memory Seat (If Equipped)
The memory function
controls the driver’s
seat cushion and recliner
positions and is located
on the driver’s door
trim panel.
You can also reshape the side wing area of the lower
seatback for more lateral support.
It does not store the lumbar or back support positions.
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.
1. Adjust the driver’s seat to your desired position.
To set your memory seat, do the following:
2. Press the SET button and then press the 1 or 2
side of the memory control within five seconds.
When your vehicle is in PARK (P), press the 1 or 2
button of the memory control to recall the seat setting.
To do the same thing for a second driver, follow the
preceding steps, but press the other number of the
memory control. The memory feature only works when
the transmission is in PARK (P).
1-5
Heated Front Seats (If Equipped)
Reclining Seatbacks
If your vehicle has heated
front seats, the ignition
must be in RUN for them
to operate.
The control for the driver’s side heated seat is located on the
driver’s side door panel. The control for the passenger’s side
heated seat is located on the passenger’s side door panel.
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 on the button will illuminate for each heat
setting anytime the heated seats are operating.
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.
1-6
To adjust the front seatback, lift the lever located on the
outboard side of the seat. Release the lever to lock the
seatback where you want it. Lift the lever again upward
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.
CAUTION:
But don’t have a seatback reclined if your vehicle
is moving.
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
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 on the
folded up seat cushion. When the seat is returned
to the passenger position, be sure the head
restraints are installed properly.
Slide the head restraint up or down so that the top of the
restraint is closest to the top of your ears. This position
reduces the chance of a neck injury in a crash.
1-8
Rear Seats
Utility: The rear seat may have a 60/40 split seat which
may be folded down to give you more cargo space.
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).
Suburban/Yukon XL: The second row rear seat of
Suburban/Yukon XL models may have a 60/40 split seat
or rear bucket seats. Either side of the rear seat may be
folded down to give you more cargo space.
On both Utility and Suburban/Yukon XL models with
60/40 split bench seats, before folding the rear seat back
down on the driver’s side, insert the center occupant lap
belt latch plate into the loop provided on the underside
of the folded forward seat cushion. 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 models with rear bucket seats,
the head restraints need to be removed in order to fold
the rear seat. To do this, lift the head restraints up until
they stop. Press in the button on the side of the head
restraint guide cap and lift up on the head restraint.
This will need to be repeated on the other cap.
The head restraint can be removed and stored in the
space provided on the folded up seat cushion.
On Suburban/Yukon XL models with bucket seats,
the seatbacks can be reclined. To adjust the seatback,
pull the lever, located at the base of the back, forward.
Release the lever to lock the seatback where you want it.
Pull the lever again and the seatback will go to an
upright position. In order to fold the back of a bucket
seat into a horizontal load floor, the back must be in its
full upright position and not reclined.
1-9
On Suburban/Yukon XL models with 60/40 split bench
seats, before folding the rear seat on the driver’s side,
insert the two buckles into the retainer in the seatback.
That way, 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.
To fold, pull up on the
strap loop at the rear of
the seat cushion. Then,
pull the seat cushion up
and fold it forward.
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.
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 front seat forward and/or
bringing the front seatback more upright. On the passenger
side of Suburban/Yukon XL models, the lever at the base
of the seat must be turned rearward to release the seatback.
1-10
To return the seat to the passenger position on a
Suburban/Yukon XL, lift the floor load panels and latch
them into the seatback. Lift the seatback up and push
rearward all the way. Then lower the seat cushion until it
latches into position.
Pull forward on the seatback and up on the seat cushion
to make sure the seat is securely in place.
Check to see that the buckles on the driver’s side
seatback are accessible to the outboard and center
occupant and are not under the seat cushions.
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.
Be sure to return the head restraints to the upright
position on utility models.
Folding the Third Seat
Utility: The seatback of the third seat (if equipped) in
utility models also folds down on the floor.
To fold the seatback down,
pull up on the release lever,
labeled 1, located on the
rear of the seatback. Then
push the seatback forward.
Entry to the Third Seat
Suburban/Yukon XL: The passenger’s side of the
second row 60/40 or rear bucket seats has an easy entry
feature. This makes it easy to get in and out of the
third seat, if your vehicle has one.
To operate the easy entry seat, turn the release lever,
located near the back of the seat rearward.
Tilt the seatback toward the front of the vehicle by
pulling the top of the seatback forward.
When you do, the seat bottom will release. Just pull the
seat forward until it stops.
To return the seat to the passenger position, pull up
on the release lever labeled 1 and then pull up on the
seatback until it locks into the upright position.
Push forward on the seatback to make sure it is
locked into position.
Be sure to return the seat to the passenger position when
finished. Pull forward and push rearward on the seat to
make sure it is locked in place.
1-11
If still more cargo space is
desired, the third seat can
also be folded and tumbled
forward or removed if
necessary by pulling up on
the release lever labeled 2.
To return the seat to the passenger position, pull up on
the release lever and then pull up on the seatback until it
locks into the upright position. Push forward on the
seatback to make sure it is locked into position.
If still more cargo space is desired, the third seat can
also be folded and tumbled forward by using the lever,
labeled 2. To return the seats to their original position,
reverse the above steps.
Fold and Tilt Feature (Suburban/Yukon XL
Third Seat)
The seat locks into place and does not need to be
removed when carrying cargo. See “Removing the
Third Row Seats” for utility later in this section for
removal instructions.
Suburban/Yukon XL: The seatback of the third seat
(if equipped) in Suburban/Yukon XL models also folds
down to create more cargo space.
To fold the seatback down, pull up on the release lever,
labeled 1, located on the rear of the seatback, then push
the seatback forward.
1-12
Once the third seatback has been folded down, the
entire seat can be tilted forward to create a flat load
floor. To do this, you will need to enter the rear cargo
area of the vehicle. Make sure the head restraints have
been lowered completely.
With the seat folded, unlatch the seat from the floor by
pulling up on the lever located under the carrying handle
at the rear of the seat labeled 2. Lift the rear of the seat
up, off of the floor. You will not be able to unlatch the
seat from the floor unless the seatback is folded down.
Tilt the seat fully forward and secure it in place using
the support rod located on the underside of the seat,
passenger side. Make sure the support rod pin is fully
engaged in the lock.
Push and pull on the seat, making sure the support rod is
holding it firmly in place. Use the seat in this position
only when necessary for additional cargo space.
CAUTION:
If the support rod isn’t properly engaged, the
folded third row seat could come loose in a
sudden stop or crash. That could cause injury to
people and damage to your vehicle. Always be
sure the support rod is properly engaged when
the third row seat is folded forward.
To return the seat to its seating position, push forward
on the seat and release the support lock rod. Secure the
support rod in its stored position on the underside of the
seat. Lower the seat to the floor and let the seat drop into
place. Lift up on the carrying handle to make sure the
seat is locked in place.
Return the seatback to the upright position by pulling
up on the release lever labeled 1 before the back can be
folded upright. Pull the seatback forward to make sure it
is locked into place.
Removing the Third Row Seat
Utility: If your vehicle has third row seating, it can be
taken out for more cargo space.
To remove the seat, fully open the rear doors and enter
the rear of the vehicle.
Fold the seatback forward
into the seat cushion by
using the lever labeled 1.
The seat cannot be
removed unless the
seatback is folded.
1-13
To unlatch the seat from the
back of the floor, pull up on
the release lever labeled 2
at the rear of the seat and
lift the rear of the seat up,
off of the floor.
Fold the seatback forward into the seat cushion by using
the lever labeled 1. The seat cannot be removed unless
the seatback is folded.
To unlatch the seat from the floor, pull up on the release
lever labeled 2 at the rear of the seat and lift the rear of
the seat up, off of the floor.
Pull on the strap, labeled 3, at the rear of the seat to
release the front seat latches. Then, pull the seat straight
back, towards the rear of the vehicle and remove it.
There are wheels at the front of the seat to assist you.
Replacing the Rear Seat
Pull on the release lever located in the lower middle to
unlatch the seat from the front of the floor and pull the
seat out. Use one hand on the release lever and the other
on the handle to pull the seat out.
Suburban/Yukon XL: If your vehicle has third row
seating, it can be taken out for more cargo space.
To remove the seat, fully open the rear doors and enter
the rear of the vehicle.
1-14
Utility: To put the seat back in, place the front of the
seat on the load floor facing towards the front of the
vehicle. Slide the wheels into the slots on the floor and
lock into place using the hooks there. Once the latches
are engaged, let the seat drop into place. Release the
lever labeled 1 to return the seat to its upright position.
Push and pull on the seat to make sure it is locked
into place.
Suburban/Yukon XL: To put the seat back in, place
the front of the seat on the load floor, facing the front
of the vehicle. While holding the rear of the seat up, use
the wheels on the front of the seat to roll it towards the
seat hooks in the floor. When the latches are engaged in
the hooks, let the seat drop into place. Lift up on the
carrying handle to make sure the seat is locked in place.
Raise the seatback into the upright position. Push and
pull on the seat to make sure it is locked into place.
The seatback cannot be raised to the upright position
unless the seat is secured to the floor.
CAUTION:
A seat that isn’t locked into place properly can
move around in a collision or sudden stop. People
in the vehicle could be injured. Be sure to lock
the seat into place properly when installing it.
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.
1-15
In most states and Canadian provinces, the law says to
wear safety belts. Here’s why: They work.
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.
1-16
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!
Why Safety Belts Work
When you ride in or on anything, you go as fast as it goes.
Put someone on it.
Take the simplest vehicle. Suppose it’s just a seat on wheels.
1-17
Get it up to speed. Then stop the vehicle. The rider
doesn’t stop.
1-18
The person keeps going until stopped by something.
In a real vehicle, it could be the windshield ...
or the instrument panel ...
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.
1-19
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.
1-20
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.

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.
1-22
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.
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.
1-23
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.
1-24
Q:
What’s wrong with this?
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.
A:
The shoulder belt is worn under the arm. It should
be worn over the shoulder at all times.
1-25
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.
1-26
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.
1-27
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.
1-28
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.
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 “supplemental restraints”
to the safety belts. All air bags are designed to
work with safety belts but don’t replace them.
CAUTION: (Continued)
CAUTION: (Continued)
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, side or low-speed frontal
crashes. And, for unrestrained occupants, frontal
air bags may provide less protection in frontal
crashes than more forceful air bags have
provided in the past. 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.
1-29
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.”
1-30
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.
How the Air Bag Systems Work
Where are the air bags?
The right front passenger’s frontal air bag is in the
instrument panel on the passenger’s side.
The driver’s frontal air bag is in the middle of the
steering wheel.
The driver’s side impact air bag is in the side of the
driver’s seatback closest to the door.
1-31
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. 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 and don’t let seat covers block the
inflation path of a side impact air bag.
The right front passenger’s side impact air bag is in the
side of the passenger’s seatback closest to the door.
1-32
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, side
impacts, or rear 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-Road
Driving” in the Index for more tips on off-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.
1-33
How does an air bag restrain?
What will you see after an air bag inflates?
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 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.
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.
1-34
D Your vehicle is equipped with a crash sensing and
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.
D
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.
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:
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.
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.
1-35
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.
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.
CAUTION:
For up to two 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.
1-36
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.
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.
1-37
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.
1-38
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.
2. Push the latch plate into the buckle until it clicks.
Pull up on the latch plate to make sure it is secure.
1-39
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.
1-40
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.
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.
To unlatch the belt, just push the button on the buckle.
1-41
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. 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.
1-42
Third Row Seat
2. Place the guide over the belt and insert the two edges
of the belt into the slots of the guide.
1-43
3. Be sure that the belt is not twisted and it lies flat.
The guide must be on top of the belt.
1-44
Second Row Seat
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.
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 from
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.
1-45
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.
1-46
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.
1-47
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.
1-48
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.
CAUTION:
Restraint Systems for Children
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 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.
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.
1-49
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.
1-50
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.
Q:
A:
How do child restraints work?
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.
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.
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.
1-51
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.
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.
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:
1-52
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.
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.
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.
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.
1-53
Suburban/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 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 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.
Suburban/Yukon XL Second Row Seat.
Bucket seats similar.
1-54
Suburban/Yukon XL Third Row Seat
Utility Second Row Seat
Utility models: A child restraint with a top strap
should only be used in the second row. Don’t use a child
restraint with a top strap in the right front passenger’s
position or in the third row, because there’s no place to
anchor the top strap.
Anchor the top strap to one of these 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. Raise the head restraint
and route the top strap under it.
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.
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.
1-55
Securing a Child Restraint in a Rear
Outside Seat Position
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.
You’ll be using the lap-shoulder belt. See the earlier
part about the top strap if the child restraint has one.

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.
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.
6. Push and pull the child restraint in different
directions to be sure it is secure.
See the earlier part about the top strap if the child

Front Seat Position
Don’t use child restraints in this position. The restraints
won’t work properly.
1-59
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.
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.
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.
1-60
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.
1-61
Older Children
Q:
A:
What is the proper way to wear safety belts?
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.
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.
1-62
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.
1-63
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.
1-64
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.
Replacing Restraint System Parts
After a Crash
If you’ve had a crash, do you need new belts?
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 belts.
If belts are cut or damaged, replace them. Collision
damage also may mean you will need to have safety belt
or seat parts repaired or replaced. New parts and repairs
may be necessary even if the belt 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.
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.)

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.
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.

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 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

headlamps and taillamps will flash for up to 30 seconds.
This can be turned off by pressing the horn 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 only four transmitters
matched to it.
2-10
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.
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:
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 in the slot between the covers of the
transmitter housing near the key ring hole. Remove
the bottom by twisting the dime.
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.
2-11
Liftgate Caution
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.

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.
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.
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.
Parking at Night
Theft
Parking Lots
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.
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?

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

D Lock all the doors except the driver’s.
2-13
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).
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:
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.
2-14
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.
PasslockR
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.
2-15
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.
2-16
Ignition Positions
You can use your key to turn the ignition switch to
five different positions.
ACCESSORY (A): 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.
LOCK (B): 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.
OFF (C): 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).
RUN (D): This is the position for driving.
START (E): This position starts your engine.
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
OnStarR 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.
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.
2-17
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. When the
engine starts, let go of the key. Use the accelerator
pedal to maintain engine speed, if you have to, until
your engine has run for a while.
2-18
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.
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.
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.
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.
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.
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.
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.
2-19
Automatic Transmission Operation
PARK (P): This locks your rear wheels. It’s the best
position to use when you start your engine because your
vehicle can’t move easily.
CAUTION:
There are several different positions for your shift lever.
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.
2-20
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).
CAUTION: (Continued)
CAUTION: (Continued)
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. If you’re pulling a trailer, see “Towing a
Trailer” in the Index.
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.
2-21
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.
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.
2-22
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
selector 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:
Tow/Haul Mode Selector Switch
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.
Your vehicle is equipped with a tow/haul mode. The
selector switch 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 Autoridet
feature, if your vehicle is so equipped, to enhance
the ride when trailering or with a loaded vehicle.
See “Autoridet” in the Index.
2-23
Four-Wheel Drive (If Equipped)
Front Axle Locking Feature
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.
The front axle locks and unlocks automatically when
you shift the transfer case. Some delay for the axle to
lock or unlock is normal.
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.
2-24
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 switches
are located to the left of the
instrument panel cluster.
Use these switches to shift into and out of
four-wheel drive.
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.
2-25
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.
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.
2-26
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.
Shifting to 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 to 2HI
Press and release the 2HI switch. This can be done at
any speed (except when shifting from 4LO).
Shifting to 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 to NEUTRAL
To shift the transfer case to NEUTRAL, first make sure
the vehicle is parked so that it will not roll:
1. Set the parking brake.
2. Start the vehicle or turn the ignition to RUN.
3. Connect the vehicle to the towing vehicle.
4. Put the transmission in NEUTRAL (N).
5. Shift the transfer case to 2HI.
6. 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.
7. Shift the transmission to REVERSE (R) for one
second, then shift the transmission to DRIVE (D)
for one second.
8. Turn the ignition to OFF.
9. Place the transmission shift lever in PARK (P).
10. Release the parking brake prior to towing.
2-27
Shifting Out of NEUTRAL
Parking Brake
To shift out of NEUTRAL:
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.
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.
2-28
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.
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. That section shows
what to do first to keep the trailer from moving.
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.
2-29
1. Hold the brake pedal down with your right foot and
set the parking brake.
2. Move the shift lever into PARK (P) position like this:
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).
D Pull the shift lever toward you.
2-30
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).
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).
2-31
Shifting Out of PARK (P)
Parking Over Things That Burn
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.
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.
2-32
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
ever you 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 switch 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.
2-33
Level Control (If Equipped)
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.
2-34
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 suspension.
t
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 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 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.
t
The Autoride feature will provide a superior vehicle
ride and handling under a variety of passenger and
loading conditions.

Cruise Control
Turn Signal 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 will flash in the
direction of the turn or
lane change.
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).
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.
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.
2-37
Headlamp High/Low Beam Changer
Windshield Wipers
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 also
will be on.
Flash-To-Pass Feature
This feature allows you to use your high-beam

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.
Rear Window Washer/Wiper
This switch is located on

Cruise Control
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.
2-40
CAUTION:
D Cruise control can be dangerous where
D
you can’t drive safely at a steady speed.
So, don’t use your cruise control on
winding roads or in heavy traffic.
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.
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.
United States

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.
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 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.

down to the cruise control speed you set earlier.
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.
Using Cruise Control on Hills
Reducing Speed While Using Cruise Control
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.
D Press and hold the SET button at the end of the lever
Ending Cruise Control
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.
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.
There are two ways to turn off either the cruise control:

Programming the Transmitter
3. Using both hands, press the hand-held transmitter
button and the desired button on the HomeLink
Transmitter. Continue to press both buttons
through Step 4.
Do not use the HomeLinkR Transmitter with any garage
door opener that does not have the “stop and reverse”
feature. This includes any garage door opener model
manufactured before April 1, 1982.
4. Hold down both buttons until you see the light on
the HomeLink Transmitter flash rapidly. The rapid
flashing indicates that the HomeLink Transmitter has
been programmed. Release both buttons once the
light starts to flash rapidly.
Be sure that people and objects are clear of the garage
door you are programming.
If you have trouble programming the HomeLink
Transmitter, make sure that you have followed the
directions exactly as described and that the battery in the
hand-held transmitter is not dead. If you still cannot
program it, turn the hand-held transmitter end over end
and try again. The HomeLink Transmitter may not work
with older garage door openers that do not meet current
Federal Consumer Safety Standards. If you cannot
program the transmitter after repeated attempts, refer to
“Training a Garage Door Opener with Rolling Codes”
later in this section or contact the manufacturer of the
unit at 1-800-355-3515.
Your vehicle’s engine should be turned off while
programming the transmitter. Follow these steps to
program up to three channels:
1. If you have previously programmed a transmitter
channel, proceed to Step 2. Otherwise, hold down
the two outside buttons on the HomeLink
Transmitter until the indicator light begins to flash
rapidly (after 20 seconds). Then release the buttons.
This procedure initializes the memory and erases any
previous settings for all three channels.
2. Decide which one of the three channels you want to
program. Hold the end of the hand-held transmitter
about 2 to 5 inches (5 to 13 cm) away from the
surface of the HomeLink Transmitter so that you
can still see the indicator light.
Be sure to keep the original hand-held transmitter
in case you need to erase and reprogram the
HomeLink Transmitter.
2-61
Canadian Owners: During programming, the
hand-held transmitter may automatically stop
transmitting after one or two seconds. In this case, you
should press and re-press the button on the hand-held
transmitter every two seconds without ever releasing the
button on the HomeLink Transmitter. Release both
buttons when the indicator light on the HomeLink
Transmitter begins to flash rapidly.
Operating the Transmitter
Press and hold the appropriate button on the
HomeLinkR Transmitter. The indicator light
comes on while the signal is being transmitted.
If the hand-held transmitter appears to program the
HomeLink Transmitter but does not open your garage
door, and if the garage door opener was manufactured
after 1996, the garage door opener may have a “rolling
code” system. A rolling code system changes the code
of the garage door opener every time you open or close
the garage door.
To determine if you have this system, press the
button on the HomeLink Transmitter that you have
programmed already. If the indicator light flashes
rapidly for one to two seconds, then turns solid, the
garage door opener has a rolling code system. In a
rolling code system, the garage door motor head unit
must be trained to the HomeLink Transmitter.
2-62
Training a Garage Opener with a “Rolling
Code” Feature (If Equipped)
If you have not previously programmed the hand-held
transmitter to the HomeLinkR Transmitter, see
“Programming the Transmitter” listed previously.
If you have completed this programming already, you
now need to train the garage door opener motor head
unit to recognize the HomeLink Transmitter. Refer to
your garage door opener owner’s manual for the proper
transmitter training procedure for your garage door
opener brand.
1. Find the training button on the garage door opener
motor head unit. The exact location and color will
vary by garage door opener brand. If you have
difficulty finding the training button, refer to your
garage door opener owner’s manual.
Because of the steps involved, it may be helpful
to have another person assist in programming
the transmitter.
2. Press the training button on the garage door
opener motor head unit. An indicator light will
begin to flash when the motor head unit enters the
training mode.
Following this step, you have 30 seconds to
start Step 3.
3. Return to the HomeLink Transmitter in your vehicle
and firmly press and release the HomeLink Transmitter
button you have already programmed for two to three
seconds. Press and release the button again (you may
need to do this step up to three times) to make sure
that the HomeLink Transmitter has been trained to the
garage door opener motor head unit. Check that the
training was successful. The motor head unit indicator
light should no longer be flashing.

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.
2-69
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.
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.
2-70
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.
If the driver’s belt is already buckled, neither the chime
nor the light will come on.
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.
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.
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.

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.
Voltmeter
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.
2-72
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.
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
Engine Coolant Temperature Gage
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.
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.
The “Problems on the Road,” section of this manual shows
what to do. See “Engine Overheating” in the Index.
2-74
Transmission Temperature Gage
(If Equipped)
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.
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).
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.
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), please contact your nearest dealer or the
GM Roadside Assistance Center.
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.
2-75
The following situations can cause the transmission to
operate at higher temperatures:
D

Assist System, this light
will come on when the
system is limiting wheel
spin. See “Traction Assist
System” in the Index.
High transmission fluid level
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.
2-76
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 Assist
System is active. Slippery road conditions may exist if
the LOW TRACTION light comes on, so adjust your
driving accordingly.
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.
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 TRACTION OFF 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.
The TRACTION OFF light may come on for the
following reasons:
D If you turn the system off by pressing the TAS on/off
D If you move the shift lever to FIRST (1), the light
will come on and stay on to indicate that the Traction
Assist 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

Malfunction Indicator Lamp
(Service Engine Soon Light in the United
States or Check Engine Light in Canada)
United States
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.
Canada
NOTICE:
Your vehicle is equipped with a computer which
monitors operation of the fuel, ignition and emission
control systems.
2-78
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.
NOTICE:
Modifications made to the engine, transmission,
exhaust 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.
If the Light Is Flashing
The following may prevent more serious damage to
your vehicle:
D
D
D
D
Reducing vehicle speed.
Avoiding hard accelerations.
Avoiding steep uphill grades.
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.
2-79
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.
Have you recently changed brands of fuel?
2-80
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.
2-81
Oil Pressure Gage
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.
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

Mode Knob - Automatic Operation
The right knob on the control panel allows you to
choose the direction of air delivery. 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.
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.
3-6
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 blower
fan speed will gradually increase and air will flow from
the heater 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.
Mode Knob - Manual Operation
The right knob on the control panel allows you to

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 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
HEATER and DEFROST, the recirculation feature will
not function to reduce window fogging.
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. 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.
3-11
Heating
Defogging and Defrosting
The heater works best if you keep your windows closed
while using it. On cold days, use the HEATER or
VENT/HEAT setting with the temperature knob in
the red area.
On cool, humid days, use DEFOG to keep the windshield
and side windows clear. Use DEFROST to remove fog
or ice from the windshield in extremely humid or cold
conditions. Use DEFROST with the temperature knob
toward the red area and the fan control turned all the
way to the right.
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.
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
located next to the mode
control knob.
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.
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 first.
3-12
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 VENT to direct outside air
through your vehicle. Air will flow through the
instrument panel outlets.
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.
3-13
Your vehicle has air outlets
in the center and on the
sides of the instrument
panel and also may be
equipped on the headliner.
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.
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.
3-14
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.

Understanding Radio Reception
To help avoid hearing loss or damage:
AM
D Adjust the volume control to the lowest setting.
D Increase volume slowly until you hear comfortably
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.
and clearly.
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 Delco 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 Cassette Tape Player
A tape player that is not cleaned regularly can cause
reduced sound quality, ruined cassettes or a damaged
mechanism. Cassette tapes should be stored in their
cases away from contaminants, direct sunlight and
extreme heat. If they aren’t, they may not operate
properly or may cause failure of the tape player.
Your tape player should be cleaned regularly after every
50 hours of use. Your radio may display CLN to indicate
that you have used your tape player for 50 hours without
resetting the tape clean timer. If this message appears
on the display, your cassette tape 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. If you notice a reduction in sound quality, try a
known good cassette to see if it is the tape or the tape
player at fault. If this other cassette has no improvement
in sound quality, clean the tape player.
The recommended cleaning method for your
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 using a scrubbing action, non-abrasive cleaning
cassette, it is normal for the cassette to eject because
your unit is equipped with a cut tape detection feature
and a cleaning cassette may appear as a broken tape.
To prevent the cleaning cassette from being ejected,
use the following steps.
1. Turn the ignition to RUN or ACCESSORY.
2. Turn the radio off.
3. Press and hold the TAPE AUX button for
five seconds. The tape symbol on the display will
flash for two seconds.
4. Insert the scrubbing action cleaning cassette.
5. Eject the cleaning cassette after the manufacturer’s
recommended cleaning time.
3-34
When the cleaning cassette has been ejected, the cut tape
detection feature is active again.
You may also choose a non-scrubbing action, wet-type
cleaner which uses a cassette with a fabric belt to clean
the tape head. This type of cleaning cassette will not
eject on its own. A non-scrubbing action cleaner may
not clean as thoroughly as the scrubbing type cleaner.
The use of a non-scrubbing action, dry-type cleaning
cassette is not recommended.
After you clean the player, press and hold EJECT for
five seconds to reset the CLN indicator. The radio will
display --- to show the indicator was reset.
Cassettes are subject to wear and the sound quality
may degrade over time. Always make sure the cassette
tape is in good condition before you have your tape
player serviced.
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 side without writing 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.
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.

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
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.
4-2
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.
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
D
D
D
Judgment
Muscular Coordination
Vision
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
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 many U.S. states sets the legal limit at a BAC
of 0.10 percent. In a growing number of U.S. states, and
throughout Canada, the limit is 0.08 percent. In some
other countries, it’s even lower. 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.
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.
4-4
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!
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.

Control of a Vehicle
Braking
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 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.
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
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.
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 Brakes (ABS)
Your vehicle has anti-lock brakes (ABS). 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.
Here’s how anti-lock works. Let’s say the road is wet.
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.
4-8
As you brake, your computer keeps receiving updates on
wheel speed and controls braking pressure accordingly.
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.
Traction Assist System (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.
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.
You may hear or feel the system working or notice
a lack of accelerator response, but this is normal.
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.
4-9
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 a severely 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.
4-10
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.
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 vehicle with ignition off and 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.
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
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.
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 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.
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.
4-12
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.
Off-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.
4-13
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.
4-14
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.
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.
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.
4-15
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.

Off-Road Driving with Your
Four-Wheel-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 following steps must be performed on each of the
push-pins to remove the air dam:
1. Insert the blade portion
of a flat-tip screwdriver
into the push-pin slot
and pull downward
until the push-pin
snaps loose.
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.
2. While continuing to
pull downward on the
push-pin, squeeze and
turn the expandable
end of the push-pin
with a pair of pliers
until it releases from
the retainer.
4-17
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:
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.
4-18
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
D
D
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.
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.
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.

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.
4-20
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.
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.
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?
4-21
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.
4-22
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.
Driving Uphill
Here are some other things to consider as you
approach a hill.
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

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.
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.

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.
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.
4-24
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.
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.
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.
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.
4-25
Driving Downhill
When off-roading takes you downhill, you’ll want to
CAUTION:
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.
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.
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.
4-26
Q:
A:
Am I likely to stall when going downhill?
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.
D
D
D
Apply the parking brake.
Shift to PARK (P) and, while still braking, restart
the engine.
Shift back to a low gear, release the parking brake,
and drive straight down.
If the engine won’t start, get out and get help.
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.
4-27
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.
4-28
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.
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.
4-29
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.
4-30
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
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

Night driving is more dangerous than day driving.
One reason is that some drivers are likely to be

problems, or by fatigue.
glare from headlamps behind you.
Since you can’t see as well, you may need to
slow down and keep more space between you and
other vehicles.
Slow down, especially on higher speed roads. Your
headlamps can light up only so much road ahead.
In remote areas, watch for animals.
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.
4-31
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.
Driving in Rain and on Wet Roads
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.
4-32
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.
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.
4-33
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.
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-beam headlamps -- not just your
parking lamps -- 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.
4-34
City Driving
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.
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.
4-35
Freeway Driving
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.
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.
4-36
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.
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?
4-37
Highway Hypnosis
Hill and Mountain Roads
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.
4-38
Driving on steep hills or mountains is different from
driving in flat or rolling terrain.
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.
4-39
Winter Driving
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.
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.
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.
4-40
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.
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
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.
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.
Whatever the condition -- smooth ice, packed, blowing
or loose snow -- drive with caution.
4-41
If You’re Caught in a Blizzard
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.
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.
4-42
You can run the engine to keep warm, but be careful.
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 (or batteries) charged. You will need a
well-charged battery (or batteries) to restart the vehicle,
and possibly for signaling later on with your headlamps.
Let the heater run for a while.
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.
4-43
Recreational Vehicle Towing
There may be times when you want to tow your vehicle
behind another vehicle for use at your destination. Be
sure to use the proper towing equipment designed for
recreational vehicle towing. Follow the instructions for
the towing equipment.
When towing your vehicle, turn the ignition to 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.
4-44
Four-Wheel-Drive Vehicles
Use the following procedure to tow your vehicle:
1. Firmly set the parking brake.
CAUTION:
Shifting the transfer case into NEUTRAL can
cause your vehicle to roll even if the transmission
is in PARK (P), for an automatic transmission.
You or others could be injured. Make sure the
parking brake is firmly set before you shift the
transfer case into NEUTRAL.
2. Shift the transmission to PARK (P).
3. Securely attach the vehicle being towed to the
tow vehicle.
4. Shift the transfer case to NEUTRAL (N).
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 to OFF. The OFF position unlocks
the steering column and reduces battery drain as long
as the IGN 0 fuse is removed. Unlocking the steering
column will allow the proper movement of the front
wheels and tires during towing.
4-45
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.
4-46
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.
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.
And, if you do have a heavy load, you should spread
it out.
4-47
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.
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.
4-48
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.
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.
Trailer Recommendations
For more information, see “Trailer Towing” in
the Index.
You must subtract your hitch loads from the CWR
for your vehicle. 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.
4-49
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.
4-50
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.
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 the capacity stamped on your step
bumper. You should always use a sway control
if your trailer will weigh more than the capacity
stamped on your step bumper. You can ask a
hitch dealer about sway controls.
D Consider using a sway control. 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 should 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 FIFTH (5) gear. Just
drive in FOURTH (4) gear (or, as you need to, a
lower 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.
4-51
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 AutorideR which further improves
your vehicle’s ride while towing. See “AutorideR” 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).
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
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. Your vehicle may be equipped with
AutorideR. If it is, see “AutorideR” in the Index.
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.
D When pulling a heavy trailer or a large or heavy load
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.
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

package is required on C/K-2500 models with the
VORTEC 6000 engine.
in stop and go traffic.
in busy parking lots where improved low speed
control of the vehicle is desired.

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.
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.
4-55
Hitches
Safety Chains
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:
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. If you have the factory-installed
trailering package, for vehicles equipped to pull a
trailer up to 10,500 lbs. (4 763 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.
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 the capacity stamped on your
step bumper, 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.
4-56
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.
4-57
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.
Following Distance
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.
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.
During your trip, check occasionally to be sure that the
load is secure, and that the lamps and any trailer brakes
are still working.
4-58
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
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.
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).
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.
4-59
Parking on Hills
CAUTION:
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).
5. If you have a four-wheel-drive vehicle, be sure the
transfer case is in a drive gear and not in NEUTRAL (N).
6. Release the regular brakes.
4-60
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.
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, belts, 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
Press the button at the top
of the steering column all
the way down to make your
front and rear turn signal
lamps 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.
To turn off the flashers, press the button until the
first click and release.
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.
But they won’t flash if you’re braking.
5-2
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.
Jump Starting
If your battery has run down, you may want to use
another vehicle and some jumper cables to start your
vehicle. But please use the following steps 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 ACDelcoR 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.
5-3
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.
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 an automatic transmission in
PARK (P) and a manual transmission in NEUTRAL
before setting the parking brake. Put the transmission
in PARK (P). If you have a four-wheel-drive vehicle,
be sure the transfer case is not in NEUTRAL (N).
3. Turn off the ignition on both vehicles. Unplug
unnecessary accessories plugged into the cigarette
lighter or accessory power outlets. Turn off all lamps
that aren’t needed as well as radios. This will avoid
sparks and help save both batteries. In addition,
it could save your radio!
NOTICE:
If you leave your radio on, it could be badly
damaged. The repairs wouldn’t be covered by
your warranty.
4. Open the hoods and locate the positive (+) and
negative (-) terminal locations on the other vehicle.
Your vehicle has a remote positive (+) jump starting
terminal and a remote negative (-) jump starting
terminal. The remote positive (+) terminal is located
behind a red plastic cover near the driver’s side of 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 accessory drive bracket. This is marked
“GND” on V8 engines.
5-4
You should always use the remote positive (+)
and the remote negative (-) terminals instead of
the positive (+) and negative (-) terminals on
your battery.
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 battery has enough water. You don’t
need to add water to the ACDelcoR battery
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.
5-5
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.
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.
5-6
8. Now connect the
black negative (-) cable
to the good battery’s
negative (-) cable. Use
a remote negative (-)
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
engine part of the vehicle with the dead battery or to a
remote negative (-) terminal if the vehicle has one.
9. When connecting the
cable, be sure it is not
near any engine parts
that will move.
10. Now start the vehicle with the good battery and run
the engine for awhile.
11. Try to start the vehicle with the dead battery. If it
won’t start after a few tries, it probably needs service.
12. Remove the cables in reverse order to prevent
electrical shorting. Take care that they don’t touch
each other or any other metal.
Jumper Cable Removal
A. Heavy, Unpainted Metal Engine Part
B. Good Battery
C. Dead Battery
1. Disconnect the black negative (-) cable from the
heavy, unpainted metal engine part on the vehicle
that had the dead battery.
2. Disconnect the black negative (-) cable from the
negative (-) terminal on the vehicle with the
good battery.
5-7
3. Disconnect the red positive (+) cable from the
vehicle with the good battery.
Overheated Engine Protection Operating
Mode (V8 Engines Only)
4. Disconnect the red positive (+) cable from the
other vehicle.
Should an overheated engine condition exist 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. Towing a trailer in the
overheat protection mode should be avoided.
Towing Your Vehicle
Consult your dealer or a professional towing service if
you need to have your vehicle towed. See “Roadside
Assistance” and “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.
5-8
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 monitor. See “Engine Oil” in the Index.
If Steam Is Coming From Your Engine
CAUTION: (Continued)
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.
NOTICE:
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. Just turn it off and get everyone away
from the vehicle until it cools down.
CAUTION: (Continued)
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.
5-9
If No Steam Is Coming From Your Engine
If you get an engine overheat warning 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
D
D
D
Climb a long hill on a hot day.
Stop after high-speed driving.
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.
1. If you have an air conditioner and it’s on, turn it off.
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.
2. Turn on your heater to full hot at the highest fan
speed and open the window as necessary.
You may decide not to lift the hood but to get service
help right away.
Idle for long periods in traffic.
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:
3. If you’re in a traffic jam, shift to NEUTRAL (N);
otherwise, shift to the highest gear while
driving -- DRIVE (D).
5-10
Cooling System
When you decide it’s safe to lift the hood, here’s what
you’ll see:
All Other Engines
A. Coolant Surge Tank
B. Coolant Surge Tank Pressure Cap
8100 V8 Engines
C. Engine Fan
5-11
If the coolant inside the coolant surge tank is boiling,
don’t do anything else until it cools down.
When the engine is
cold, the coolant level
should be at or above
the FILL COLD mark.
If it isn’t, you may
have a leak 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.
5-12
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-COOLR (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-COOLR is
not covered by your new vehicle warranty.
If there seems to be no leak, start the engine again. See if
the engine cooling fan speed increases when idle speed is
doubled by pushing the accelerator pedal down. If it
doesn’t, your vehicle needs service. Turn off the engine.
How to Add Coolant to the Coolant
Surge Tank
If you haven’t found a problem yet, but the coolant level
isn’t at or above the FILL COLD mark, add a 50/50
mixture of clean, drinkable water and DEX-COOLR
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.
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.
5-13
CAUTION:
Adding only plain water to your cooling system
can be dangerous. Plain water, or some other
liquid like 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-COOLR coolant.
5-14
NOTICE:
In cold weather, water can freeze and crack the
engine, radiator, heater core and other parts.
So use the recommended 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.
1. 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.
3. Then fill the coolant surge tank with the proper
mixture, to the FILL COLD mark.
2. Then keep turning the pressure cap slowly, and
remove it.
5-15
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.
5-16
5. Then replace the pressure cap. Be sure the pressure
cap is hand-tight.
Engine Fan Noise
If a Tire Goes Flat
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.
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:
You may also hear this fan noise when you start
the engine. It will go away as the fan clutch
partially disengages.
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.
5-17
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.
5-18
The following steps will tell you how to use the jack and
change a tire.

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.
5-22
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.
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.
5-23
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.
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.
5-24
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.
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.
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.

2. 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.
3. Remove all the wheel
nuts and take off the
flat tire.
4. 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.
5-27
5. After mounting
the spare, put the
wheel nuts back on
with the rounded
end of the nuts
toward the wheel.

CAUTION:
7. Tighten the nuts firmly in a crisscross sequence as
shown by turning the wheel wrench clockwise.
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.
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.

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.
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.
Store the flat tire where the spare tire was stored.
Store the tire under the rear of the vehicle in the spare
tire carrier. 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.

If You’re Stuck: In Sand, Mud,
Ice or Snow
NOTICE:
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.
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.
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.
5-34
For information about using tire chains on your vehicle,
see “Tire Chains” in the Index.
Rocking Your Vehicle To Get It Out
Using the Recovery Hooks
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.
Your vehicle may be equipped with recovery hooks.
The recovery 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.
5-35
CAUTION:
The recovery 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
Doing Your Own Service Work
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.
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.
We hope you’ll want to keep your GM vehicle all GM.
Genuine GM parts have one of these marks:
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.
Your vehicle may have an air bag system. If it does,
see “Servicing Your Air Bag-Equipped Vehicle” in the
Index before attempting to do your own service work.
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
Use regular unleaded gasoline rated at 87 octane or
higher. It is recommended that the gasoline meet
specifications which were developed by the American
Automobile Manufacturers Association (AAMA) and
endorsed by the Canadian Motor Vehicle Manufacturers
Association for better vehicle performance and engine
protection. Gasolines meeting the AAMA specification
could provide improved driveability and emission control
system performance compared to other gasolines.
6-3
In Canada, look for the
“Auto Makers’ Choice”
label on the fuel pump.
Canada Only
Be sure the posted octane is at least 87. If the octane is
less than 87, you may get a heavy knocking noise when
you drive. If it’s bad enough, it can damage your engine.
If you’re using fuel rated at 87 octane or higher and
you hear heavy knocking, your engine needs service.
But don’t worry if you hear a little pinging noise when
you’re accelerating or driving up a hill. That’s normal,
and you don’t have to buy a higher octane fuel to get
rid of pinging. It’s the heavy, constant knock that means
you have a problem.
6-4
If your vehicle is certified to meet California Emission
Standards (indicated on the underhood emission control
label), it is designed to operate on fuels that meet
California specifications. If such fuels are 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 on your instrument panel may turn on and/or your
vehicle may fail a smog-check test. See “Malfunction
Indicator Lamp” in the Index. If this occurs, return to
your authorized GM dealer for diagnosis to determine
the cause of failure. In the event it is determined that
the cause of the condition is the type of fuels used,
repairs may not be covered by your warranty.
Some gasolines that are not reformulated for low
emissions may contain an octane-enhancing additive
called methylcyclopentadienyl manganese tricarbonyl
(MMT); ask your service station operator whether or
not the fuel contains MMT. General Motors does not
recommend the use of such gasolines. If fuels containing
MMT are used, spark plug life may be reduced and your
emission control system performance may be affected.
The malfunction indicator lamp on your instrument
panel 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 deposits from forming in your engine and fuel
system, allowing your emission control system to
function properly. Therefore, you should not have
to add anything to the fuel. In addition, 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 it. 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.
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.
6-5
The fuel cap is located on the driver’s side of your vehicle.
While refueling, hang the filler cap by the tether using
the hook located on the inside of the filler door.
To remove the cap, turn it slowly to the
left (counterclockwise).
6-6
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 filler cap too quickly. This spray can happen
if your tank is nearly full, and is more likely in
hot weather. Open the fuel filler 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.
When you put the 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 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 your fuel tank and emissions system may be
damaged. See “Malfunction Indicator Lamp” in
the Index.
6-7
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.
6-8
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, first pull
the handle inside the vehicle
located under and to the left
of the steering wheel.
Then go to the front of the vehicle and pull up on the
secondary hood release located just to the passenger’s
side near the center of the grill.
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 appears on the
instrument panel, 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.
All Other Engines
8100 Engines
The engine oil dipstick has a yellow ring handle and
is located on the passenger’s side of the engine.
See “Engine Compartment Overview” in the Index
for more information on location.
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.
6-14
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
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.
All Other Engines
8100 Engines
The engine oil fill cap for the VORTEC 4800, 5300,
6000 and 8100 V8 engines is located on the passenger’s
side engine valve cover. 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.
6-15
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:
6-16
As in the chart shown previously, SAE 5W-30 is best for
your vehicle. However, you can use SAE 10W-30 if it’s
going to be 0 F (-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.
_
_
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
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 GoodwrenchR 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.
Your vehicle has a computer that lets you know when to
change your engine oil. This is not based on mileage,
but on engine revolutions and engine operating
temperature. When the computer has calculated that
the oil needs changing, the GM Oil Life System will
indicate that a change is necessary. The mileage between
oil and filter changes will vary depending on how you
drive your vehicle -- usually between 3,000 miles
(5 000 km) and 10,000 miles (16 000 km) since your
last oil and filter change. Under severe conditions, the
system may come on before 3,000 miles (5 000 km).
Never drive your vehicle more than 10,000 miles
(16 000 km) or 12 months (whichever occurs first)
without an oil change.
t
The system won’t detect dust in the oil. So, if you
drive in a dusty area, be sure to change your oil and
filter every 3,000 miles (5 000 km) or sooner.
Remember to reset the CHANGE ENGINE OIL
whenever the oil is changed.
6-17
How to Reset the CHANGE ENGINE OIL Message
To reset the CHANGE ENGINE OIL message, turn the
ignition key to RUN with the engine off. 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
Did you know that 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 real threat to the environment. If you
change your own oil, be sure to drain all free-flowing
oil from the filter before disposal. Don’t ever 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.
6-18
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 “Owner Checks and Services” in the Index to
determine when to check the indicator.
If the area inside the clear section of the indicator is
not completely yellow, no air filter service is required.
When the area inside the indicator is completely yellow,
past the red band, the words “CHANGE FILTER” will
be highlighted. After changing the air filter, press the top
button on the indicator to reset it.
Your engine air cleaner/filter is located in the
passenger’s side front corner of the engine compartment.
See “Engine Compartment Overview” in the Index for
more information on location.
1. To remove the air filter, loosen the screws on the cover.
Then lift the cover upward and remove the filter from
the engine air cleaner/filter housing. Care should be
taken to dislodge as little dirt as possible.
2. Clean the filter sealing surface and the filter housing.
3. Install the new filter.
4. Install the cover and tighten the screws on the air
cleaner cover.
Refer to the Maintenance Schedule to determine when to
replace the air filter. See “Owner Checks and Services”
in the Index.
6-19
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.
6-20
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.

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 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 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.
Be sure to get an accurate reading if you check
your transmission fluid.
6-22
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.
Then, without shutting off the engine, follow these steps:
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.
1. The red transmission dipstick handle is located at the
rear of the engine compartment, on the passenger’s
side. See “Engine Compartment Overview” in the
Index for further information on location. Flip the
handle up and then pull out the dipstick and wipe it
with a clean rag or paper towel.
6-23
2. Push it back in all the way, wait three seconds and
then pull it back out again.
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.
NOTICE:
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.
We recommend you use only fluid labeled
DEXRONR-III, because fluid with that label is
made especially for your automatic transmission.
Damage caused by fluid other than DEXRONR-III
is not covered by your new vehicle warranty.
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.

Rear Axle
When to Check Lubricant
Refer to the Maintenance Schedule to determine how
often to check the lubricant. Additional rear axle
scheduled maintenance is required when trailer towing.
See “Scheduled Maintenance Services” in the Index.
How to Check Lubricant
The proper level for the 1500 Series is from 5/8 inch to
1 5/8 inch (15 mm to 40 mm) below the filler plug.
The proper level for the 2500 Series is from 0 to 3/8 inch
(0 to 10 mm) below the filler plug. Add only enough fluid
to reach the proper level.
What to Use
Refer to the Maintenance Schedule to determine what
kind of lubricant to use. See “Recommended Fluids
and Lubricants” in the Index.
Four-Wheel Drive
Most lubricant checks in this section also apply to
four-wheel-drive vehicles. However, they have
two additional systems that need lubrication.

When the differential is at operating temperature (warm),
add enough lubricant to raise the level to the bottom of the
filler plug hole.
What to Use
Refer to the Maintenance Schedule to determine what
kind of lubricant to use. See “Recommended Fluids and
Lubricants” in the Index.
Engine Coolant
The cooling system in your vehicle is filled with
DEX-COOLR 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-COOLR 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-COOLR coolant will:
D
D
D
D
D
Give freezing protection down to -34_F (-37_C).
Give boiling protection up to 265_F (129_C).
Protect against rust and corrosion.
Help keep the proper engine temperature.
Let the warning lights and gages work as
they should.
NOTICE:
When adding coolant, it is important that you
use only DEX-COOLR (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-COOLR is not
covered by your new vehicle warranty.
6-27
What to Use
Use a mixture of one-half clean, drinkable water and
one-half DEX-COOLR 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 like 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-COOLR coolant.
6-28
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.
If the LOW COOLANT
light comes on and
stays on, it means you’re
low on engine coolant.
Checking Coolant
The coolant surge tank
is located on the
passenger’s side of the
engine compartment.
See “Engine Compartment
Overview” in the Index
for more information.
See “Low Coolant” in the Index.
Adding Coolant
If you need more coolant, add the proper DEX-COOLR
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.
The vehicle must be on a level surface. When your
engine is cold, the coolant level should be at the
FILL COLD mark.
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.
When replacing the pressure cap, make sure it is hand-tight.
6-29
Coolant Surge Tank Pressure Cap
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.

Power Steering Fluid
All Other Engines
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
8100 Engines
When to Check Power Steering Fluid
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.
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
information on its location.
6-31
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.
NOTICE:
D When using concentrated washer fluid,
D
Adding Washer Fluid
D
D
Open the cap labeled WASHER FLUID. Add washer
fluid until the tank is full.
6-32
follow the manufacturer’s instructions for
adding water.
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.
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.
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 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.
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.
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.
6-33
Checking Brake Fluid
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:
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.
6-34
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
D
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.
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.
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.
6-35
NOTICE:
Continuing to drive with worn-out brake pads
could result in costly brake repair.
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
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.
Every time you make a brake stop, your disc brakes
adjust for wear.
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.
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 have to have 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.
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.”
6-36
Replacing Brake System Parts
Battery
Your new vehicle comes with a maintenance free
ACDelcoR 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 components, chemicals
known to the State of California to cause cancer and
reproductive harm. Wash hands after handling.
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.
Contact your dealer to learn how to prepare your vehicle
for longer storage periods.
For your audio system, see “Theft-Deterrent Feature” in
the Index. To reprogram your sunroof, see “Sunroof”
also in the Index.
Bulb Replacement
For any bulb changing procedure not listed in this
section, contact your GM dealership service department.
Before you replace any bulbs, be sure that all the lamps
are off and the engine isn’t running. See “Replacement
Bulbs” in the Index for the proper types of bulbs to use.
Halogen Bulbs
CAUTION:
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.
Halogen bulbs have pressurized gas inside and
can burst if you drop or scratch the bulb. You or
others could be injured. Be sure to read and

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: (Continued)
D Underinflated tires pose the same danger
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)
6-44
D
D
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.
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.
Worn, old tires can cause accidents.
If your tread is badly worn, or if your
tires have been damaged, replace them.
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).
If you have an 8600 GVW truck (2500 series) with
LT245/75R16E tires, you can improve your ride
comfort by reducing tire inflation pressure, but only
when carrying reduced loads. If you have a maximum
of 8 passengers, and 200 lbs. (90 kg) of load, you can
set the front tires at 40 psi (280 kPa), and the rear
tires at 50 psi (350 kPa). When using the reduced tire
inflation pressure settings, don’t exceed the following
loading conditions: GVWR – 7900 lbs. (3583 kg),
GAWR FRONT – 3730 lbs. (1692 kg), GAWR
REAR – 4410 lbs. (2000 kg). When carrying loads
greater than 8 passengers and 200 lbs. (90 kg) and/or
when pulling a trailer, you must inflate your tires to the
pressure shown on the Certification/Tire label.
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.
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.
6-45
When to Check
Check your tires once a month or more.
Also, check the tire pressure of the spare tire.
How to Check
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.
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.
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.
6-46
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.
When It’s Time for New Tires
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.
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.
6-47
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).
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.
6-48
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:
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.
Uniform Tire Quality Grading
Treadwear
Quality grades can be found where applicable on the
tire sidewall between tread shoulder and maximum
section width. For example:
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.
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.
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.
6-49
Temperature -- A, B, C
Wheel Alignment and Tire Balance
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.
The wheels on your vehicle were aligned and balanced
carefully at the factory to give you the longest tire life
and best overall performance.
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.
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.
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.
6-50
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.
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 an accident. If you have to replace a
wheel, use a new GM original equipment wheel.
6-51
Tire Chains
NOTICE:
If your vehicle has P265/75R16, LT265/75R16,
P265/70R16 or P265/70R17 size tires, don’t use
tire chains. They can damage your vehicle
because there’s not enough clearance.
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.
NOTICE: (Continued)
6-52
NOTICE: (Continued)
If you have a tire size other than P265/75R16,
LT265/75R16, P265/70R16 or P265/70R17, 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.

Here are some cleaning tips:
D
D
D
D
D
Always read the instructions on the cleaner label.
Clean up stains as soon as you can -- before they set.
Carefully scrape off any excess stain.
Use a clean cloth or sponge, and change to a clean area
often. A soft brush may be used if stains are stubborn.
If a ring forms on fabric after spot cleaning, clean the
entire area immediately or it will set.
Using Multi-Purpose Interior 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. Mix powdered cleaner following the directions on
the container label to form thick suds.
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 Multi-Purpose
Interior 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.
4. Use suds only and apply with a clean sponge.
Don’t saturate the material and don’t rub it roughly.
2. First, clean with cool water and allow to
dry completely.
5. As soon as you’ve cleaned the section, use a sponge
to remove the suds.
3. If a stain remains, follow instructions for
Multi-Purpose Interior Cleaner.
6. Wipe cleaned area with a clean, damp towel or cloth.
7. Wipe with a clean cloth and let dry.
6-54
Cleaning Vinyl
Cleaning the Top of the Instrument Panel
Use warm water and a clean cloth.
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.
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 Interior Plastic Components
Cleaning Leather
Use only a mild soap and water solution on a soft
cloth or sponge. Commercial cleaners may affect the
surface finish.
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.
Care of Safety Belts
D For stubborn stains, use a leather cleaner. See your
dealer for this product.
D Never use oils, varnishes, solvent-based or abrasive
Keep belts clean and dry.
CAUTION:
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.
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.
6-55
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.
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.
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.
6-56
Clean the outside of the windshield with GM Windshield
Cleaner, Bon AmiR Powder (non-scratching glass cleaning
powder), GM Part No. 1050011. 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
Cleaning Exterior Lamps/Lenses
The paint finish on your vehicle provides beauty, depth
of color, gloss retention and durability.
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.”
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.
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 may have 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.
6-57
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.
Cleaning Aluminum or
Chrome-Plated Wheels (If Equipped)
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.
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.
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.
6-58
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.
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
Sheet Metal Damage
To clean your tires, use a stiff brush with a tire cleaner.
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.
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.
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.
6-59
Underbody Maintenance
Chemical Paint Spotting
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.
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.
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.
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.

Electrical System
Power Windows and Other Power Options
Add-On Electrical Equipment
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.
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.
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 -- like the radio or cigarette
lighter -- and use its fuse, if it is the correct amperage.
Replace it as soon as you can.
6-63
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.

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
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.
7-2
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.
How This Section is Organized
This maintenance schedule is divided into five parts:
“Part A: Scheduled Maintenance Services” shows
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.
7-3
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.
7-4
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-road in the recommended manner. See
“Off-Road Driving With Your Four-Wheel-Drive
Vehicle” in the Index.
D use the recommended fuel. See “Fuel” in the Index.
Scheduled Maintenance
The services shown in this schedule up to 100,000 miles
(166 000 km) should be performed after 100,000 miles
(166 000 km) at the same intervals. The services shown
at 150,000 miles (240 000 km) should be performed at
the same interval after 150,000 miles (240 000 km).
See “Owner Checks and Services” and “Periodic
Maintenance Inspections” following.
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 Systemt (or every 12 months,
whichever occurs first). Reset the system. The system
will show you when to change the oil -- usually between
3,000 miles (5 000 km) and 10,000 miles (16 000 km)
since your last oil change. Under severe conditions, the
indicator may come on before 3,000 miles (5 000 km).
Never drive your vehicle more than 10,000 miles
(16 000 km) or 12 months without an oil and
filter change.
The system won’t detect dust in the oil. So if you drive
in a dusty area, be sure to change your oil and filter
every 3,000 miles (5 000 km) or sooner if the CHANGE
ENGINE OIL message appears. Remember to reset
the Oil Life System when the oil and filter have been
changed. See “Oil Life System” in the Index for
information on resetting.
An Emission Control Service.
7-6
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, parking brake cable guides, and brake front
axle. Ball joints should not be lubricated unless their
temperature is 10_F (-12_C) or higher, or they
could be damaged.

Make sure tires are inflated to the correct pressures.
Don’t forget to check your spare tire. See “Tires”
in the Index for further details.
Cassette Deck Service
Clean cassette deck. Cleaning should be done every
50 hours of tape play. See “Audio Systems” in the
Index for further details.
7-17
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.
7-18
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.
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.

pivots, spring anchor, release pawl, rear compartment
hinges, outer liftgate handle pivot points, rear door
detent link, roller mechanism, liftgate handle pivot
points, latch bolt, fuel door hinge, cargo door hinge,
locks and folding seat hardware. Part D tells you what
to use. More frequent lubrication may be required when
exposed to a corrosive environment.
CAUTION:
When you are doing this check, the vehicle could
move suddenly. If it does, you or others could be
injured. Follow the steps below.
1. Before you start, be sure you have enough room
around the vehicle.
2. Firmly apply both the parking brake and the regular
brake. See “Parking Brake” in the Index if necessary.
NOTE: Do not use the accelerator pedal, and be
ready to turn off the engine immediately if it starts.
3. Try to start the engine in each gear. The starter
should work only in PARK (P) or NEUTRAL (N).
If the starter works in any other position, your
vehicle needs service.
7-19
Automatic Transmission Shift Lock Control
System Check
CAUTION:
When you are doing this check, the vehicle could
move suddenly. If it does, you or others could be
injured. Follow the steps below.
1. Before you start, be sure you have enough room
around the vehicle. It should be parked on a
level surface.
2. Firmly apply the parking brake. See “Parking Brake”
in the Index if necessary.
NOTE: Be ready to apply the regular brake
immediately if the vehicle begins to move.
7-20
3. With the engine off, turn the key to the RUN
position, but don’t start the engine. Without applying
the regular brake, try to move the shift lever out
of PARK (P) with normal effort. If the shift lever
moves out of PARK (P), your vehicle needs service.
Ignition Transmission Lock Check
While parked, and with the parking brake set, try to turn
the ignition key to LOCK in each shift lever position.
D The key should turn to LOCK only when the shift
lever is in PARK (P).
D The key should come out only in LOCK.
Parking Brake and Automatic Transmission
PARK (P) Mechanism Check
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.
7-22
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.
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
Brake 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.
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.
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.

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.)
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).
D Dealership name and location
D Vehicle delivery date and present mileage
8-3
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.
You may contact the BBB using the toll-free telephone
number or write them at the following address:
BBB Auto Line
Council of Better Business Bureaus, Inc.
4200 Wilson Boulevard
Suite 800
Arlington, VA 22203-1804
Telephone: 1-800-955-5100
This program is available in all 50 states and the District
of Columbia. Eligibility is limited by vehicle age,
mileage and other factors. General Motors reserves the
right to change eligibility limitations and/or discontinue
its participation in this program.

8-7
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.
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.
Generally it is not possible to provide a like-vehicle as a
courtesy rental.
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.
Additional Program Information
Warranty 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.
Your vehicle comes with a separate warranty booklet
that contains detailed warranty information.

REPORTING SAFETY
DEFECTS TO THE UNITED
STATES GOVERNMENT
If you believe that your vehicle has a defect which could
cause a crash or could cause injury or death, you should
immediately inform the National Highway Traffic
Safety Administration (NHTSA), in addition to
notifying General Motors.
If NHTSA receives similar complaints, it may open an
investigation, and if it finds that a safety defect exists in
a group of vehicles, it may order a recall and remedy
campaign. However, NHTSA cannot become involved
in individual problems between you, your dealer or
General Motors.
To contact NHTSA, you may either call the Auto Safety
Hotline toll-free at 1-800-424-9393 (or 366-0123 in the
Washington, D.C. area) or write to:
NHTSA, U.S. Department of Transportation

You can also obtain other information about motor
vehicle safety from the hotline.
