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:
Index
A good place to look for what you need is the Index in
back of the manual. It’s an alphabetical list of what’s in
the manual, and the page number where you’ll find it.
These mean there is something that could hurt
you or other people.
In the caution area, we tell you what the hazard is. Then
we tell you what to do to help avoid or reduce the
hazard. Please read these cautions. If you don’t, you or
others could be hurt.

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

CAUTION:
But don’t have a seatback reclined if your vehicle
is moving.
1-8
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.

Head Restraints
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.
The seatbacks fold forward to let you access the rear of
the cab.
To fold a front seatback
forward, pull this lever
forward and fold the
seatback forward.
On some models, the head restraints tilt forward and
rearward also.
To tilt the head restraints forward, grasp the top of the
restraint and move it forward to where you want it to go
until you hear a click. It will then be locked into that
position until you need to move it again. Pulling it
forward past the last position will allow the restraint to
return to its upright position.
Seatback Latches
To return the seatback to the upright position, just push
the seatback rearward until it latches. After returning the
seatback to its upright position, pull the seatback
forward to make sure it is locked.
CAUTION:
If the seatback isn’t locked, it could move
forward in a sudden stop or crash. That could
cause injury to the person sitting there. Always
press rearward on the seatback to be sure it
is locked.

Easy Entry Seat (Extended Cab Only)
CAUTION:
If any easy entry seat isn’t locked, it can move. In
a sudden stop or crash, the person sitting there
could be injured. And, even if there is no crash or
sudden stop, a driver sitting in an unlocked easy
entry seat could be startled by the sudden
movement and hit the wrong control or pedal,
causing an accident. After you’ve used it, be sure
to push rearward on any easy entry seat to be
sure it is locked.
The manual driver side front bucket seat and the manual
driver side split bench seat of your vehicle have an easy
entry feature. This makes it easy to get in and out of the
rear seat.

When you do, the seat bottom will release. Just pull or
push the seat forward until it stops.
To return the seat to its regular position, return the
seatback to its upright position, then push the whole seat

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.
CAUTION:
It is extremely dangerous to ride in a cargo area,
inside or outside of a vehicle. In a collision,
people riding in these areas are more likely to be
seriously injured or killed. Do not allow people to
ride in any area of your vehicle that is not
equipped with seats and safety belts. Be sure
everyone in your vehicle is in a seat and using a
safety belt properly.
Your vehicle has a light
that comes on as a reminder
to buckle up. (See “Safety
Belt Reminder Light” in
the Index.)
In most states and Canadian provinces, the law says to
wear safety belts. Here’s why: They work.

You never know if you’ll be in a crash. If you do have a
crash, you don’t know if it will be a bad one.
A few crashes are mild, and some crashes can be so
serious that even buckled up a person wouldn’t survive.
But most crashes are in between. In many of them,
people who buckle up can survive and sometimes walk
away. Without belts they could have been badly hurt
or killed.
After more than 30 years of safety belts in vehicles,
the facts are clear. In most crashes buckling up does
matter ... a lot!
Why Safety Belts Work

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?
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.
1-16
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.
I

or
mat
i

ovi

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 (to see how, see “Seats” in the Index)
so you can sit up straight.
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.
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.
5. To make the lap part tight, pull down on the buckle
end of the belt as you pull up on the shoulder belt.
The safety belt locks if there’s a sudden stop or crash, or
if you pull the belt very quickly out of the retractor.

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.

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.
Here are the most important things to know about the air
bag system:
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 System
This part explains the air bag system.
Your vehicle has “Next Generation” frontal air
bags -- one air bag for the driver and another air bag
for the right front passenger.
Next Generation frontal air bags are designed to help
reduce the risk of injury from the force of an inflating
air bag. But even these air bags must inflate very
quickly if they are to do their job and comply with
federal regulations.
I
nf
or
mat
i
onPr
ovi
dedby:
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 -- even Next Generation air
bags -- are designed to work with safety belts,
but don’t replace them. Air bags 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, Next Generation air
bags may provide less protection in frontal
crashes than more forceful air bags have
provided in the past. Everyone in your vehicle
should wear a safety belt properly -- whether or
not there’s an air bag for that person.
1-25
yellowblue
CAUTION:
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. This is true
even with Next Generation frontal air bags.
Safety belts help keep you in position before and
during a crash. Always wear your safety belt,
even with Next Generation air bags. The driver
should sit as far back as possible while still
maintaining control of the vehicle.
1-26
CAUTION:
Children who are up against, or very close to, any
air bag when it inflates can be seriously injured
or killed. This is true even though your vehicle
has Next Generation frontal air bags. 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” and see the caution labels on the
sunvisors and the right front passenger’s

There is an air bag readiness
light on the instrument
panel, which shows the air
bag symbol.
How the Air Bag System Works
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.
Where are the air bags?
The driver’s air bag is in the middle of the
steering wheel.

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.
When should an air bag inflate?
The right front passenger’s air bag is in the instrument
panel on the passenger’s side.
1-28
An air bag is designed to inflate in a moderate to severe
frontal or near-frontal crash. The air bag will 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 air bag is not
designed to inflate in rollovers, side impacts or rear
impacts, because inflation would not help the occupant.
I

or
mat
i
onPr
ovi
dedby:

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.
Inflation is determined by the angle of the impact and
how quickly the vehicle slows down in frontal or
near-frontal impacts.
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. 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 and in the instrument panel in front of the
right front passenger.
How does an air bag restrain?
In moderate to severe frontal or near-frontal collisions,
even belted occupants can contact the steering wheel or the
instrument panel. Air bags supplement 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 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 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.
What will you see after an air bag inflates?
After an air bag inflates, it quickly deflates, so quickly
that some people may not even realize the air bag
inflated. Some components of the air bag module -- the
steering wheel hub for the driver’s air bag, or the
instrument panel for the right front passenger’s
bag -- 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 vents in the deflated air bags. Air bag
inflation doesn’t prevent the driver from seeing or from
being able to steer the vehicle, nor does it stop people
from leaving the vehicle.

D Your vehicle is equipped with a crash sensing and
diagnostic module, which records information about
the air bag system. The module records information
about the readiness of the system, when the
sensors are activated and driver’s safety belt usage
at deployment.
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 door.
D Let only qualified technicians work on your air
bag system. Improper service can mean that your
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 they
inflate, 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.
1-30
If you damage the covering for the driver’s or the
right front passenger’s air bag, the bag may not
work properly. You may have to replace the air
bag module in the steering wheel or both the air
bag module and the instrument panel for the
right front passenger’s air bag. Do not open or
break the air bag coverings.

If your vehicle ever gets into a lot of water -- such as
water up to the carpeting or higher -- or if water enters
your vehicle and soaks the carpet, the air bag controller
can be soaked and ruined. If this ever happens, and then
you start your vehicle, the damage could make the air
bags inflate, even if there’s no crash. You would have to
replace the air bags as well as the sensors and related
parts. If your vehicle is ever in a flood, or if it’s exposed
to water that soaks the carpet, you can avoid needless
repair costs by turning off the vehicle immediately and
disconnecting the battery cables. Don’t let anyone start
the vehicle under any circumstances. See your dealer
for service.

This switch should only be turned to AIR BAG OFF if
the person in the right front passenger’s position is a
member of a passenger risk group identified by the
national government as follows:
Medical Condition. A passenger has a medical
condition which, according to his or her physician:
Infant. An infant (less than 1 year old) must ride in the
front seat because:
D makes the potential harm from the passenger air bag
D my vehicle has no rear seat;
D my vehicle has a rear seat too small to accommodate
a rear-facing infant seat; or
D the infant has a medical condition which, according
to the infant’s physician, makes it necessary for the
infant to ride in the front seat so that the driver can
constantly monitor the child’s condition.
Child age 1 to 12. A child age 1 to 12 must ride in the
front seat because:
D my vehicle has no rear seat;
D although children ages 1 to 12 ride in the rear
seat(s) whenever possible, children ages 1 to 12
sometimes must ride in the front because no space is
available in the rear seat(s) of my vehicle; or
D causes the passenger air bag to pose a special risk
for the passenger; and
in a crash greater than the potential harm from
turning off the air bag and allowing the passenger,
even if belted, to hit the dashboard or windshield in
a crash.
CAUTION:
If the right front passenger’s air bag is turned off
for a person who isn’t in a risk group identified
by the national government, that person won’t
have the extra protection of an air bag. In a
crash, the air bag wouldn’t be able to inflate and
help protect the person sitting there. Don’t turn
off the passenger’s air bag unless the person
sitting there is in a risk group.

Servicing Your Air Bag-Equipped Vehicle
Air bags affect how your vehicle should be serviced.
There are parts of the air bag system in several places
around your vehicle. You don’t want the system to
inflate while someone is working on your vehicle. Your
dealer and the GM Service Manual have information
about servicing your vehicle and the air bag system. To
purchase a service manual, see “Service and Owner
Publications” in the Index.
CAUTION:
To turn the right front passenger’s air bag on again,
insert your ignition key into the switch, push in, and
move the switch to the ON position.
For up to 10 minutes after the ignition key is
turned off and the battery is disconnected, an air
bag can still inflate during improper service. You
can be injured if you are close to an air bag when
it inflates. Avoid wires wrapped with yellow tape
or yellow connectors. They are probably part of
the air bag system. Be sure to follow proper
service procedures, and make sure the person
performing work for you is qualified to do so.
The air bag system does not need regular maintenance.

Adding Equipment to Your Air
Bag-Equipped Vehicle
Q:
What if I add a snow plow? Will it keep the air
bags from working properly?
Q:
If I add a push bumper or a bicycle rack to the
front of my vehicle, will it keep the air bags
from working properly?
A:
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.
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.
Q:
Is there anything I might add to the front 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 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.

Rear Seat Passengers
It’s very important for rear seat passengers to buckle up!
Accident statistics show that unbelted people in the rear

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.
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

The safety belt locks if there’s a sudden stop or a crash.
The safety belt also locks if you pull the belt very
quickly out of the retractor.
CAUTION:
You can be seriously hurt if your shoulder belt is
too loose. In a crash, you would move forward
too much, which could increase injury. The
shoulder belt should fit against your body.
The lap part of the belt should be worn low and snug on
the hips, just touching the thighs. In a crash, this applies
force to the strong pelvic bones. And you’d be less likely
to slide under the lap belt. If you slid under it, the belt
would apply force at your abdomen. This could cause
serious or even fatal injuries. The shoulder belt should go
over the shoulder and across the chest. These parts of the
body are best able to take belt restraining forces.

Children
Everyone in a vehicle needs protection! That includes
infants and all children smaller than adult size. Neither
the distance traveled nor the age and size of the traveler

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.
Smaller Children and Babies

Children who are up against, or very close to, any
air bag when it inflates can be seriously injured
or killed. This is true even though your vehicle
has Next Generation frontal air bags. 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.
1-43
yellowblue
CAUTION:
Smaller children and babies should always be
restrained in a child or infant restraint. The
instructions for the restraint will say whether it is
the right type and size for your child. A very
young child’s hip bones are so small that a
regular belt might not stay low on the hips, as it
should. Instead, the belt will likely be over the
child’s abdomen. In a crash, the belt would apply
force right on the child’s abdomen, which could
cause serious or fatal injuries. So, be sure that
any child small enough for one is always properly
restrained in a child or infant restraint.
1-44
Infants need complete support, including support for the
head and neck. This is necessary because an infant’s
neck is weak and its head weighs so much compared
with the rest of its body. In a frontal crash, an infant in a
rear-facing restraint settles into the restraint, so the crash
forces can be distributed across the strongest part of the
infant’s body, the back and shoulders. A baby should be
secured in an appropriate infant restraint. This is so
important that many hospitals today won’t release a
newborn infant to its parents unless there is an infant
restraint available for the baby’s first trip in a
motor vehicle.

Q:
What are the different types of add-on
child restraints?
A:
Add-on child restraints are available in four basic
types. When selecting a child restraint, take into
consideration not only the child’s weight and size,
but also whether or not the restraint will be
compatible with the motor vehicle in which it will
be used.
An infant car bed (A) is a special bed made for use

will have a label saying that it meets Federal Motor
Vehicle Safety Standards.
CAUTION:
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.
The instructions that come with the infant or child
restraint will show you how to do that. Both the owner’s
manual and the child restraint instructions are important,
so if either one of these is not available, obtain a
replacement copy from the manufacturer.
Where to Put the Restraint
(Regular Cab Pickup)
The child restraint must be secured properly in the right
front passenger seat. If you want to secure a rear-facing
child restraint in the right front passenger’s seat, turn off
the passenger’s air bag. See “AIR BAG OFF Switch”
and “Securing a Child Restraint in the Right Front Seat

A child in a rear-facing child restraint can be
seriously injured or killed if the right front
passenger’s air bag inflates, even though your
vehicle has Next Generation frontal air bags. This
is because the back of the rear-facing child
restraint would be very close to the inflating air
bag. Be sure to turn off the air bag before using a
rear-facing child restraint in the right front
seat position.

Rear Seat Position (Extended Cab Pickup)
Don’t use child restraints in this position. The restraints
won’t work properly.
If you have an extended cab pickup, you can secure a
child restraint in the center rear seat position.
There is limited space in the rear seating area of an
extended cab model. If you want to secure a child restraint
in a rear seating position of an extended cab model,
especially in the rear center position, be sure to study the
instructions that came with your child restraint to see if
there is enough room to secure your seat properly.

You’ll be using the lap belt. Be sure to follow the
instructions that came with the child restraint. Secure the
child in the child restraint when and as the instructions
say. See the earlier part about the top strap if the child
restraint has one.
1. Make the belt as long as possible by tilting the latch
plate and pulling it along the belt.
2. Put the restraint on the seat.
3. Run the vehicle’s safety belt through or around the
restraint. The child restraint instructions will show
you how.
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. To tighten the belt, pull its free end 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.

Securing a Child Restraint in the Right
Front Seat Position
Your vehicle has a right front passenger air bag. There’s
a switch on the instrument panel that you can use to turn
off the right front passenger’s air bag when you want to
secure a rear-facing child restraint at the right front
passenger’s position. See “AIR BAG OFF Switch” in
the Index for more on this, including important
safety information.

CAUTION:
CAUTION:
A child in a rear-facing child restraint can be
seriously injured or killed if the right front
passenger’s air bag inflates, even though your
vehicle has Next Generation frontal air bags. This
is because the back of the rear-facing child
restraint would be very close to the inflating air
bag. Be sure to turn off the air bag before using a
rear-facing child restraint in the right front seat
position. If a forward-facing child restraint is
suitable for your child, always move the
passenger seat as far back as it will go.
Although a rear seat is a safer place, you can secure a
forward-facing child restraint in the right front seat.

If the air bag readiness light ever comes on when
you have turned off the air bag, it means that
something may be wrong with the air bag system.
The right front passenger’s air bag could inflate
even though the switch is off.
If your vehicle is a regular cab pickup and this
ever happens, don’t let anyone whom the
national government has identified as a member
of a passenger air bag risk group sit in the right
front passenger’s position (for example, don’t
secure a rear-facing child restraint in your
vehicle) until you have your vehicle serviced.

CAUTION: (Continued)
If your vehicle is an extended cab pickup and this
ever happens, don’t let anyone whom the
national government has identified as a member
of a passenger air bag risk group sit in the right
front passenger’s position (for example, don’t
secure a rear-facing child restraint in the right

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. Your vehicle has a right front passenger’s air bag. If
you are using a rear-facing child restraint in this seat,
make sure the air bag is turned off. (See “AIR BAG
OFF Switch” in the Index.) If your child restraint is
forward-facing, always move the seat as far back as
it will go before securing it in this seat. (See “Seats”
in the Index.)
2. Put the restraint on the 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.

will move freely again and be ready to work for an adult
or larger child passenger.
If you were using a rear-facing child restraint, turn on
the right front passenger’s air bag when you remove the
rear-facing child restraint from the vehicle unless the
person who will be sitting there is a member of a
passenger air bag risk group. See “AIR BAG OFF
Switch” in the Index.
CAUTION:
6. 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.
7. Push and pull the child restraint in different
directions to be sure it is secure.
1-62
If the right front passenger’s air bag is turned off
for a person who isn’t in a risk group identified
by the national government, that person won’t
have the extra protection of an air bag. In a
crash, the air bag wouldn’t be able to inflate and
help protect the person sitting there. Don’t turn
off the passenger’s air bag unless the person
sitting there is in a risk group. See “AIR BAG
OFF Switch” in the Index for more on this,

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.
Larger Children
Accident statistics show that children are safer if they
are restrained in the rear seat. But they need to use the
safety belts properly.
D Children who aren’t buckled up can be thrown out in
a crash.
D Children who aren’t buckled up can strike other
people who are.

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.
1-64
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.

CAUTION:
Never do this.
Here a child is sitting in a seat that has a
lap-shoulder belt, but the shoulder part is behind
the child. If the child wears the belt in this way, in
a crash the child might slide under the belt. The
belt’s force would then be applied right on the
child’s abdomen. That could cause serious or
fatal injuries.
Wherever the child sits, the lap portion of the belt
should be worn low and snug on the hips, just touching
the child’s thighs. This applies belt force to the child’s
pelvic bones in a crash.

Safety Belt Extender
Replacing Restraint System Parts
After a Crash
If the vehicle’s safety belt will fasten around you, you
should use it.
If you’ve had a crash, do you need new belts?
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.
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.)

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.
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.
Remote Panic Alarm
NOTICE:
When the button with the horn symbol on the key
transmitter is pressed, the horn will sound and the
headlamps and taillamps will flash for up to 30 seconds.
This can be turned off by pressing the horn button again,
waiting for 30 seconds, or starting the vehicle.
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.

Theft
Vehicle theft is big business, especially in some cities.
Although your vehicle has a number of theft-deterrent
features, we know that nothing we put on it can make it
impossible to steal. However, there are ways you can help.
Key in the Ignition
If you leave your vehicle with the keys inside, it’s an
easy target for joy riders or professional thieves -- so
don’t do it.
When you park your vehicle and open the driver’s door,
you’ll hear a chime reminding you to remove your key
from the ignition and take it with you. Always do this.
Your steering wheel will be locked, and so will your
ignition. If you have an automatic transmission, taking
your key out also locks your transmission. Also
remember to lock the doors.
2-10
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.
Parking at Night
Park in a lighted spot, close all windows and lock your
vehicle. Remember to keep your valuables out of sight.
Put them in a storage area, or take them with you.
Parking Lots
If you park in a lot where someone will be watching
your vehicle, it’s best to lock it up and take your keys.
But what if you have to leave your ignition key? What if
you have to leave something valuable in your vehicle?
D Put your valuables in a storage area, like your
glove box.
D Valuables can be locked in the center floor console.

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

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 light 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.
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:
Your vehicle is equipped with the Passlock
theft-deterrent system.
1. From inside the vehicle, lower the driver’s window
and open the driver’s door.
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.
2. Activate the system by locking the doors with the
power door lock switch while the door is open, or
with the remote keyless entry transmitter.
3. Get out of the vehicle, close the door and wait for the
SECURITY message to go out.
4. Then reach in through the window, unlock the door
with the manual door lock and open the door. This
should set off the alarm.
If the alarm does not sound when it should but the
vehicle’s headlamps flash, check to see if the horn
works. The horn fuse may be blown. To replace the fuse,
see “Fuses and Circuit Breakers” in the Index.
If the alarm does not sound or the vehicle’s headlamps
do not flash, the vehicle should be serviced by an
authorized service center.
2-12
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.

Ignition Positions
NOTICE:
CAUTION:
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.
Leaving children in a vehicle with the ignition

Key Release Button (Manual Transmission)
NOTICE:
The ignition key cannot be
removed from the ignition
of manual transmission
vehicles unless the key
release button is used.
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? If it is, then turn the
steering wheel left and right while you turn the
key hard. But 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.
To remove the key on manual transmission vehicles,
turn the key to OFF, then press the button and turn the
key to LOCK. Do not hold the button in while turning
the key to OFF. Pull the key straight out.

Engine Coolant Heater (If Equipped)
CAUTION:
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.
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.
3. Plug it into a normal, grounded 110-volt AC outlet.

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.
If your vehicle is equipped with an automatic
transmission, it features an electronic shift position
indicator within the instrument 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 OFF position 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)
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 (N). 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 (N). See “Shifting Into
PARK (P)” in the Index. If you’re pulling a
trailer, see “Towing a Trailer” in the Index.
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 vehicle is being towed.
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.

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.

Tow/Haul Mode (Automatic Transmission)
NOTICE:
If your rear wheels can’t rotate, don’t try to
drive. This might happen if you were stuck in
very deep sand or mud or were up against a solid
object. You could damage your transmission.
Also, if you stop when going uphill, don’t hold
your vehicle there with only the accelerator
pedal. This could overheat and damage the
transmission. Use your brakes or shift into
PARK (P) to hold your vehicle in position
on a hill.
On cold days, approximately 32_F (0_C) or colder, your
transmission is designed to shift differently until the
engine reaches normal operating temperature. This is
intended to improve heater performance.
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

Here’s how to operate
your transmission.
FIRST (1): Press the clutch pedal and shift into
FIRST (1). Then, slowly let up on the clutch pedal as
you press the accelerator pedal. Shift into FIRST (1)
only when the vehicle is below 5 mph (8 km/h). If you
try to shift down into FIRST (1) at excessive vehicle
speeds, the shift lever will not move into the FIRST (1)
position until vehicle speed is reduced.
SECOND (2): Press the clutch pedal and shift into
SECOND (2). Then, slowly let up on the clutch pedal as
you press the accelerator pedal.
FIRST (1) is intended only for heavy loads or trailer
towing and is not recommended for normal driving.
During the first 500 miles (805 km) of vehicle use, start
your vehicle moving in FIRST (1). This allows clutch
components to break-in properly.
2-24
You can shift into SECOND (2) when you’re going less
than 20 mph (32 km/h). If you’ve come to a complete
stop and it’s hard to shift into SECOND (2), put the shift
lever into NEUTRAL (N) and let up on the clutch.
Press the clutch pedal back down. Then shift into
SECOND (2). If you try to downshift into SECOND (2)
at excessive vehicle speeds, the shift lever will not move
into the SECOND (2) position until the vehicle speed
is reduced.

Shift Light
Four-Wheel Drive (If Equipped)
If you have a manual
transmission, you may have
a SHIFT light. This light
will show you when to shift
to the next higher gear for
best fuel economy.
If your vehicle has four-wheel drive, you can send your
engine’s driving power to all four wheels for extra
traction. To get the most satisfaction out of four-wheel
drive, you must be familiar with its operation. Read the
part that follows before using four-wheel drive. See the
appropriate text for the transfer case in your vehicle.
NOTICE:
When this light comes on, you can shift to the next
higher gear if weather, road and traffic conditions allow.
For the best fuel economy, accelerate slowly and shift
when the light comes on.
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.
While you accelerate, it is normal for the light to go
on and off if you quickly change the position of
the accelerator.
If your vehicle has four-wheel drive and is equipped
with a manual transmission, disregard the SHIFT light
when the transfer case is in 4-Wheel Low.
Ignore the SHIFT light when you downshift.
Front Axle Locking Feature

four-wheel drive.
The 4WD indicator will
light up when you shift into
four-wheel drive and the
front axle engages.
2-28
An indicator on the bezel near the lever shows you the
transfer case settings:
2-Wheel High (2H): 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.
4-Wheel High (4H): 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.

CAUTION:
Shifting the transfer case to NEUTRAL (N) can
cause your vehicle to roll even if the transmission
is in PARK (P), or if you have a manual
transmission, even if you are in gear. You or
someone else could be seriously injured. Be sure
to set the parking brake before placing the
transfer case in NEUTRAL (N). See “Parking
Brake” in the Index.
You can shift from 2-Wheel High (2H) to 4-Wheel High
(4H) or from 4-Wheel High (4H) to 2-Wheel High (2H)
while the vehicle is moving. Your front axle will engage
faster if you take your foot off of the accelerator for a
couple of seconds after you shift. In extremely cold
weather, it may be necessary to stop or slow the vehicle
to shift into 4-Wheel High (4H).
To shift into or out of 4-Wheel Low (4L) or
NEUTRAL (N):
1. Slow the vehicle to a roll, about 1 to 3 mph
(2 to 5 km/h) and shift an automatic transmission
into NEUTRAL (N), or with a manual transmission,
press the clutch pedal.
NEUTRAL (N): Shift to this setting only when your
vehicle needs to be towed. The ignition switch must be
in the RUN position in order to shift the lever into
NEUTRAL (N). See “Recreational Vehicle
Towing”or“Towing your vehicle”in the Index.
2. Shift the transfer case shift lever in one
continuous motion.
4-Wheel Low (4L): 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.
Remember that driving in 4-Wheel High (4H) or
4-Wheel Low (4L) may reduce fuel economy. Also,
driving in four-wheel drive on dry pavement could
cause your tires to wear faster and make your transfer
case harder to shift and run noisier.
Don’t pause in NEUTRAL (N) as you shift the transfer
case into 4-Wheel Low (4L), or your gears could clash.

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.

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.
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.
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 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

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 (N), 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

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).
Shifting Out of PARK (P)
(Automatic Transmission Only)
CAUTION:
Before shifting out of PARK (P) you must fully
apply your regular brakes. Your vehicle can roll.
If you have left the engine running, the vehicle
can move suddenly. You or others could be
injured. If you’re pulling a trailer, see “Towing a
Trailer” in the Index.
Torque Lock (Automatic Transmission)
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).
Your vehicle has a brake-transmission shift interlock
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.

Before you get out of your vehicle, put your manual
transmission in REVERSE (R), turn off the engine, and
firmly apply the parking brake.
If you are parking on a hill, or if you are pulling a
trailer, see “Towing a Trailer” in the Index.
Parking Over Things That Burn

Running Your Engine While You’re
Parked (Automatic Transmission)
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.)
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 (N) 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 (N). Always
set your parking brake. Follow the proper steps to be
sure your vehicle won’t move. See “Shifting Into

Manual Selectable Ride (If Equipped)
The main function of this system is to provide superior
ride comfort while trailering or fully loaded, as well as
for unloaded driving. This system also helps to provide:
D Improved trailering stability
D Improved handling response when trailering or
fully loaded
This button is on the center
of the instrument panel near
the radio. Press it to activate
the selectable ride setting as
desired. An indicator light
near the button will
illuminate whenever
the system is active.
It is recommended to use this system as follows:

NORMAL levels of ride control or damping.
D For optimum ride comfort when trailering, fully
loaded, driving off-road, or when personal
preferences demand more control the button should
be pressed in with the indicator light illuminated.
This switch position indicates FIRM levels of ride
control or damping.
The following guide can also be used to help determine
the best setting.
NORMAL: The indicator light will be off when the
system is in this setting. Use for normal city and
highway driving. Provides a smooth, soft ride when the
vehicle is unloaded.
FIRM (Unloaded): Press the switch to activate this
setting, the indicator light will illuminate. Use this
setting when road conditions or personal preference
demand more control. Provides more “feel” or response
to the road conditions.
FIRM (Loaded): Press the switch to activate this
setting, the indicator light will illuminate. Use this
setting to minimize trailer inputs to vehicle or when the
vehicle is fully loaded. This setting is also appropriate
for off-road driving.

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

Resuming a Set Speed
Setting Cruise Control
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.
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 it.
1. Move the cruise control switch to ON.
2. Get up to the speed you want.
3. Press in the SET button at the end of the lever
and release it.
Once you’re going about 25 mph (40 km/h) or more,
you can move the cruise control switch from ON to
R/A for about a half a second.
You’ll go right back up to your chosen speed and
stay there.
If you hold the switch at R/A longer than half a second,
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.

Increasing Speed While Using Cruise Control
Passing Another Vehicle While Using Cruise Control
There are two ways to go to a higher speed:
Use the accelerator pedal to increase your speed. When
you take your foot off the pedal, your vehicle will slow
down to the cruise control speed you set earlier.
D Use the accelerator pedal to get to the higher speed.
Press the SET button at the end of the lever, then
release the button and the accelerator pedal. You’ll
now cruise at the higher speed.
D Move the cruise switch from ON to R/A. Hold it
there until you get up to the speed you want, and
then release the switch. To increase your speed in
very small amounts, move the switch to R/A for less
than half a second. Each time you do this, your
vehicle will go about 1 mph (1.6 km/h) faster.
Reducing Speed While Using Cruise Control
D Press and hold the SET button at the end of the lever
until you reach the lower speed you want, then
release it.
D To slow down in very small amounts, press the SET
button for less than half a second. Each time you do
this, you’ll go 1 mph (1.6 km/h) slower.
Using Cruise Control on Hills
How well your cruise control will work on hills depends
upon your speed, load and the steepness of the hills.
When going up steep hills, you may want to step on the
accelerator pedal to maintain your speed. When going
downhill, you may have to brake or shift to a lower gear
to keep your speed down. Of course, applying the brake
takes you out of cruise control. Many drivers find this to
be too much trouble and don’t use cruise control on
steep hills.
Ending Cruise Control
There are two ways to turn off the cruise control:
D Step lightly on the brake pedal.
D Move the cruise control switch to OFF.

with Compass (If Equipped)
Your vehicle may have an electrochromic inside
rearview mirror.
When on, an electrochromic mirror automatically dims
to the proper level to minimize glare from lights behind
you after dark.
Inside Day/Night Rearview Mirror
Pull the tab under the mirror toward you to reduce glare
from headlamps behind you after dark. Push the tab
away from you for normal daytime operation.

Compass Operation
Press the COMP switch once briefly to turn the compass
on or off.
When the ignition and the compass feature are on, the
compass will show two character boxes for
approximately two seconds. After two seconds, the
mirror will display the compass heading.
When cleaning the mirror, use a paper towel or similar
material dampened with glass cleaner. Do not spray
glass cleaner directly on the mirror as that may cause the
liquid cleaner to enter the mirror housing.
Mirror Operation
The right side of the switch located at the bottom of the
mirror turns the electrochromic mirror on and off. The
LED, located to the right of the switch, will come on
when the electrochromic mirror is turned on. To turn the
mirror on, press and hold the MIRROR button for three
seconds. The mirror will darken and remain dark until
the button is released. To turn the mirror off, press and
release the MIRROR button.
Compass Calibration
The compass may need calibration if:
D After five seconds, the display does not show a
compass heading (“N” for North, for example), there
may be a strong magnetic force interfering with the
compass. Such interference may be caused by a
magnetic antenna mount, magnetic note pad holder
or a similar magnetic item.
D The compass does not display the correct heading
and the compass zone variance is set correctly.
In order to calibrate, the letter “C” must be displayed in
the mirror compass windows. If “C” is not displayed,
push in the “COMP” button for approximately eight
seconds or until the letter “C” is displayed.

The compass can be calibrated in one of two ways:
D Drive the vehicle in circles at 5 mph (8 km/h) or less
until the display reads a direction, or
D Drive the vehicle on your everyday routine and after
several turns the compass will become calibrated and
will display a direction.
Compass Variance
The compass is set in zone eight upon leaving the
factory. It will be necessary to adjust the compass to
compensate for compass variance if you live outside
zone eight. Under certain circumstances, as during a
long distance cross-country trip, it will be necessary to
adjust for compass variance. Compass variance is the
difference between earth’s magnetic north and true
geographic north. If not adjusted to account for compass
variance, your compass could give false readings.
3. Press the COMP button on the bottom of the mirror
until the new zone number appears in the display.
After you stop pressing the button in, the display will
show a compass direction within a few seconds.
To adjust for compass variance:
1. Press and hold the COMP button, located at the
bottom of the mirror, for three seconds until a zone
number appears in the display.
2. Find your current location and variance zone number
on the following zone map.

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.
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 has a message center that works along with
the warning lights and gages. See “Message Center” in
the Index.
Safety Belt Reminder Light
When the key is turned to RUN or START, a chime will
come on for about six seconds to remind people to
fasten their safety belts, unless the driver’s safety belt is
already buckled.
The safety belt light will
also come on and stay on
for about 20 seconds, then
it will flash for about
55 seconds. If the driver’s
belt is already buckled,
neither the chime nor the
light will come on.
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.

Air Bag Readiness Light
AIR BAG OFF 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, the passenger air bag suppression
circuit and the crash sensing and diagnostic module. For
more information on the air bag system, see “Air Bag”
in the Index.
When you turn the right front passenger’s air bag off,
this light will come on and stay on to remind you that
the air bag has been turned off. This light will go off
when you turn the air bag back on again. See “AIR BAG
OFF Switch” in the Index for more on this, including
important safety information.
This light will come on
when you start your engine,
and it will flash for a few
seconds. Then the light
should go out. This means
the system is ready.
If the air bag readiness light stays on after you start the
engine or comes on when you are driving, your air bag
system may not work properly. Have your vehicle
serviced right away.
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.

CAUTION:
If the right front passenger’s air bag is turned off
for a person who isn’t in a risk group identified
by the national government, that person won’t
have the extra protection of an air bag. In a
crash, the air bag wouldn’t be able to inflate and
help protect the person sitting there. Don’t turn
off the passenger’s air bag unless the person
sitting there is in a risk group. See “AIR BAG
OFF Switch” in the Index for more on this,
including important safety information.
CAUTION:
CAUTION: (Continued)
If your vehicle is a regular cab pickup and this
ever happens, don’t let anyone whom the
national government has identified as a member
of a passenger air bag risk group sit in the right
front passenger’s position (for example, don’t
secure a rear-facing child restraint in your
vehicle) until you have your vehicle serviced.
If your vehicle is an extended cab pickup and this
ever happens, don’t let anyone whom the
national government has identified as a member
of a passenger air bag risk group sit in the right
front passenger’s position (for example, don’t
secure a rear-facing child restraint in the right
front passenger’s seat) until you have your
vehicle serviced.
If the air bag readiness light ever comes on when
you have turned off the air bag, it means that
something may be wrong with the air bag system.
The right front passenger’s air bag could inflate
even though the switch is off.

Voltmeter
When your engine is not
running, but the ignition is
in RUN, this gage shows
your battery’s state of
charge in DC volts.
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.
Shift Light (If Equipped)
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.
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.
This light is used on some models with
manual transmissions.
The SHIFT indicator light will help you get the best fuel
economy. See “Shift Light” or “Shift Speeds” in the

Brake System Warning Light
CAUTION:
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 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.
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.
Anti-Lock Brake System Warning Light
If the warning light comes on, there could be a brake
problem. Have your brake system inspected right away.
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.
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.)
2-74
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

Engine Coolant Temperature Gage
The “Problems on the Road,” section of this manual
shows what to do. See “Engine Overheating” in
the Index.
Transmission Temperature Gage
(If Equipped)
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.
If your vehicle has a heavy
duty automatic
transmission, you will have
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. The transmission will return to normal shifting
patterns when the transmission fluid temperature falls
below 260_F (127_C).
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.
See “Message Center” in the Index for
further information.
If the transmission fluid reaches temperatures of
approximately 275_F (135_C) or greater, the message
center will display a TRANS HOT...IDLE ENG warning
message. Pull the vehicle off the roadway when it is safe
to do so. Set the parking brake, place the transmission in
PARK (P) and allow the engine to idle until the
transmission temperature falls below 260_F (127_C).
If the transmission continues to operate above 265_F
(130_C), please contact your nearest dealer or the
GM Roadside Assistance Center.
The following situations can cause the transmission to
operate at higher temperatures:
D

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 light
comes on to indicate that there is a problem and service
is required. Malfunctions often will be indicated by the

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
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.
2-77

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 the light stops flashing and remains on steady, see “If
the Light Is On Steady” following.
If the light continues to flash, when it is safe to do so,
stop the vehicle. Find a safe place to park your vehicle.
Turn the key off, wait at least 10 seconds and restart the
engine. If the light remains on steady, see “If the Light
Is On Steady” following. If the light is still flashing,
follow the previous steps, and drive the vehicle to your
dealer or qualified service center for service.
If the Light Is On Steady
You may be able to correct the emission system
malfunction by considering the following:
Did you recently put fuel into your vehicle?
If so, reinstall the fuel cap, making sure to fully install
the cap. See “Filling Your Tank” in the Index. The
diagnostic system can determine if the fuel cap has been
left off or improperly installed. A loose or missing fuel
cap will allow fuel to evaporate into the atmosphere.
A few driving trips with the cap properly installed
should turn the light off.
Did you just drive through a deep puddle of water?
If you are towing a trailer, reduce the amount of
cargo being hauled as soon as it is possible.

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.
Oil Pressure Gage
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).
Have you recently changed brands of fuel?
If so, be sure to fuel your vehicle with quality fuel (see
“Fuel” in the Index). Poor fuel quality will cause your
engine not to run as efficiently as designed. You may
notice this as stalling after start-up, stalling when you
put the vehicle into gear, misfiring, hesitation on
acceleration or stumbling on acceleration. (These
conditions may go away once the engine is warmed up.)
This will be detected by the system and cause the light

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.
Oil pressure may vary with engine speed, outside
temperature and oil viscosity, but readings above the
low pressure zone indicate the normal operating range.
A reading in the low pressure zone may be caused by a
dangerously low oil level or some other problem
causing low oil pressure. Check your oil as soon as
possible. See “Check Eng Oil Pressure” and “Engine

The system will automatically switch to the recirculation
mode to lower the system load and improve interior
comfort. The OUTSIDE AIR and RECIRCULATION
button LEDs will not change. The system will return to
the OUTSIDE AIR function when the system load
is reduced.
A/C: Press this button to turn the air conditioning
on and off. The system will cool and dehumidify the air
inside the vehicle when the A/C light is on.
Air conditioning will be automatically disabled when
the outside temperature drops below a level at which air
conditioning is ineffective.
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, below the fan knob,
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)
Your vehicle may be 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.

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 a gasoline engine and
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.
Rear Window Defogger (If Equipped)
If you see lines running across the rear window, you
have a rear window defogger. The lines warm the glass.
To turn on the rear window
defogger, press this button
next to the fan control knob.
If you use the engine coolant heater before starting your
engine in cold weather, 20_F (-8_C) or lower, your
heating system will produce warmer air faster, to heat
the passenger compartment in cold weather.
The rear window defogger
will only work if the
ignition switch is turned to
RUN. For best results, clear
the window of as much
snow or ice as possible first.
The use of an engine coolant heater also 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. For more information, see “Engine
Coolant Heater” in the Index.
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.

Do not attach a temporary vehicle license, tape or decals
across the defogger grid on the rear window.
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.
Your vehicle has air
outlets in the center and
on the sides of your
instrument panel.
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.
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 and turn the knob to the right to
allow air flow. When you close an outlet, it will increase
the flow of air coming out of any outlets that are open.
The center outlet does not completely shut off airflow.

Ventilation Tips
Audio Systems
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
blower fan all the way to the right for a few moments
before driving. This helps clear the intake ducts of
snow and moisture, and reduces the chance of
fogging the inside of your windows.
D Keep the air path under the front seats clear of
objects. This helps air to circulate throughout
your vehicle.
D The use of hood air deflectors may adversely
affect the performance of the heating and air
conditioning system.

Understanding Radio Reception
To help avoid hearing loss or damage:
D Adjust the volume control to the lowest setting.
D Increase volume slowly until you hear comfortably
and clearly.
AM
The range for most AM stations is greater than for FM,
especially at night. The longer range, however, can
cause stations to interfere with each other. AM can pick
up noise from things like storms and power lines. Try
reducing the treble to reduce this noise if you ever get it.
FM Stereo
FM stereo will give you the best sound, but FM signals
will reach only about 10 to 40 miles (16 to 65 km). Tall
buildings or hills can interfere with FM signals, causing
the sound to come and go.
Tips About Your Audio System
Hearing damage from loud noise is almost undetectable
until it is too late. Your hearing can adapt to higher
volumes of sound. Sound that seems normal can be loud
and harmful to your hearing. Take precautions by
adjusting the volume control on your radio to a safe
sound level before your hearing adapts to it.
3-26
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, 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 dealership (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.
If your vehicle is equipped with the AM-FM Stereo with
Cassette Tape Player:
1. Turn the ignition to RUN or ACCESSORY.
2. Turn the radio on.
3. Insert the scrubbing action cleaning cassette.
4. Within five seconds, press and hold the REV and
FWD buttons at the same time for three seconds. The
tape symbol on the display will flash, showing that
the cut tape detection feature is no longer active.
5. Eject the cleaning cassette after the manufacturer’s
recommended cleaning time.

If your vehicle is equipped with the AM-FM Stereo with
Cassette Tape Player and Automatic Tone Control:
1. Turn the ignition to RUN or ACCESSORY.
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.
2. Turn the radio off.
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.
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.
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

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.

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.
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.
Alcohol affects four things that anyone needs to drive
a vehicle:
The Blood Alcohol Concentration (BAC) of someone
who is drinking depends upon four things:
Drunken Driving
D
D
D
D
D The amount of alcohol consumed
D The drinker’s body weight
D The amount of food that is consumed before and
Judgment
Muscular Coordination
Vision
during drinking
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, over 17,000 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.
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.
I

i

ovi
dedby:

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

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.
And, of course, actual stopping distances vary greatly
with the surface of the road (whether it’s pavement or
gravel); the condition of the road (wet, dry, icy); tire
tread; the condition of your brakes; the weight of the
vehicle and the amount of brake force applied.
Sometimes, as when you’re driving on snow or ice, it’s
easy to ask more of those control systems than the tires
and road can provide. That means you can lose control
of your vehicle.

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.
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 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.

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.
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. 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
You can steer around the obstacle while braking hard.
As you brake, your computer keeps receiving updates on
wheel speed and controls braking pressure accordingly.
I

or
mat
i
onPr
ovi
dedby:

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.
Steering Tips
Using Anti-Lock
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.
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. On vehicles with four-wheel drive, your anti-lock
brakes work at all times -- whether you are in two-wheel
drive or four-wheel drive.
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.
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:
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.
Power Steering
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.
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.
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.
Steering

ovi
dedby:

Speed limit signs near curves warn that you should
adjust your speed. Of course, the posted speeds are
based on good weather and road conditions. Under less
favorable conditions you’ll want to go slower.
If you need to reduce your speed as you approach a
curve, do it before you enter the curve, while your front
wheels are straight ahead.
Try to adjust your speed so you can “drive” through the
curve. Maintain a reasonable, steady speed. Wait to
accelerate until you are out of the curve, and then
accelerate gently into the straightaway.
Steering in Emergencies
There are times when steering can be more effective than
braking. For example, you come over a hill and find a
truck stopped in your lane, or a car suddenly pulls out
from nowhere, or a child darts out from between parked
cars and stops right in front of you. You can avoid these
problems by braking -- if you can stop in time. But
sometimes you can’t; there isn’t room. That’s the time for
evasive action -- steering around the problem.
Your vehicle can perform very well in emergencies like
these. First apply your brakes. (See “Braking in
Emergencies” earlier in this section.) It is better to
remove as much speed as you can from a possible
collision. Then steer around the problem, to the left or
right depending on the space available.
4-10
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.

Off-Road Recovery
Passing
You may find that your right wheels have dropped off the
edge of a road onto the shoulder while you’re driving.
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.
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.
D Watch for traffic signs, pavement markings and lines.
I

or
mat
i
onPr
ovi
dedby:
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.
4-11
yellowblue
D Do not get too close to the vehicle you want to pass
while you’re awaiting an opportunity. For one thing,
following too closely reduces your area of vision,
especially if you’re following a larger vehicle. Also, you
won’t have adequate space if the vehicle ahead suddenly
slows or stops. Keep back a reasonable distance.
D When it looks like a chance to pass is coming up,
start to accelerate but stay in the right lane and don’t
get too close. Time your move so you will be
increasing speed as the time comes to move into the
other lane. If the way is clear to pass, you will have a
“running start” that more than makes up for the
distance you would lose by dropping back. And if
something happens to cause you to cancel your pass,
you need only slow down and drop back again and
wait for another opportunity.
D If other cars are lined up to pass a slow vehicle, wait
your turn. But take care that someone isn’t trying to
pass you as you pull out to pass the slow vehicle.
Remember to glance over your shoulder and check
the blind spot.
4-12
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.
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.
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.
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.
A cornering skid and an acceleration skid are best
handled by easing your foot off the accelerator pedal.
Remember: Any anti-lock brake system (ABS) helps
avoid only the braking skid.

Off-road driving can be great fun. But it does have

“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.

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.
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.
Controlling your vehicle is the key to successful
off-road driving. One of the best ways to control your

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.

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.
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.
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:
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.
D Is the path ahead clear?
D Will the surface texture change abruptly up ahead?
D Does the travel take you uphill or downhill?
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.
(There’s more discussion of these subjects later.)
D Will you have to stop suddenly or change
direction quickly?

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.
On a large hill, the incline may get steeper as you near
the top, but you may not see this because the crest of the
hill is hidden by bushes, grass or shrubs.
Here are some other things to consider as you approach
a hill.
D Is there a constant incline, or does the hill get sharply
steeper in places?
D Is there good traction on the hillside, or will the
CAUTION:
surface cause tire slipping?
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.
D Is there a straight path up or down the hill so you
won’t have to make turning maneuvers?
D Are there obstructions on the hill that can block your
path (boulders, trees, logs or ruts)?
D What’s beyond the hill? Is there a cliff, an
embankment, a drop-off, a fence? Get out and
walk the hill if you don’t know. It’s the smart way to
find out.
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.
D Is the hill simply too rough? Steep hills often have

D Use your headlamps even during the day. They make
you more visible to oncoming traffic.
D Try to drive straight up the hill if at all possible.
CAUTION:
If the path twists and turns, you might want to find
another route.
CAUTION:
Turning or driving across steep hills can be
dangerous. You could lose traction, slide
sideways, and possibly roll over. You could be
seriously injured or killed. When driving up hills,
always try to go straight up.
4-22
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.

Q:
What should I do if my vehicle stalls, or is about
to stall, and I can’t make it up the hill?
A: If this happens, there are some things you should
do, and there are some things you must not do.
First, here’s what you should do:
D Push the brake pedal to stop the vehicle and keep it
from rolling backwards. Also, apply the parking brake.
D If your engine is still running, shift the transmission
to REVERSE (R), release the parking brake, and
slowly back down the hill in REVERSE (R).
D If your engine has stopped running, you’ll need to
restart it. With the brake pedal pressed and the
parking brake still applied, shift the transmission to
PARK (P) (or, shift to NEUTRAL (N) if your
vehicle has a manual transmission) and restart the
engine. Then, shift to REVERSE (R), release the
parking brake, and slowly back down the hill as
straight as possible in REVERSE (R).
D As you are backing down the hill, put your left hand
on the steering wheel at the 12 o’clock position. This
way, you’ll be able to tell if your wheels are straight
and maneuver as you back down. It’s best that you
back down the hill with your wheels straight rather
than in the left or right direction. Turning the wheel
too far to the left or right will increase the possibility
of a rollover.
Here are some things you must not do if you stall, or are
about to stall, when going up a hill.
D Never attempt to prevent a stall by shifting into
NEUTRAL (N) (or depressing the clutch, if you
have a manual transmission) to “rev-up” the engine
and regain forward momentum. This won’t work.
Your vehicle will roll backwards very quickly and
you could go out of control.
Instead, apply the regular brake to stop the vehicle.
Then apply the parking brake. Shift to
REVERSE (R), release the parking brake, and
slowly back straight down.
D Never attempt to turn around if you are about to stall
I

when going up a hill. If the hill is steep enough to
stall your vehicle, it’s steep enough to cause you to
roll over if you turn around. If you can’t make it up
the hill, you must back straight down the hill.
4-23
yellowblue
Q:
A:
Suppose, after stalling, I try to back down the
hill and decide I just can’t do it. What should
I do?
CAUTION:
Set the parking brake, put your transmission
in PARK (P) (or the manual transmission in
FIRST (1)) 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 (N) when you leave the vehicle.
Leave it in some gear.
4-24
Shifting the transfer case to NEUTRAL (N) can
cause your vehicle to roll even if the transmission
is in PARK (P) (or, if you have the manual
transmission, even if you’re in gear). This is
because the NEUTRAL (N) 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) (or, put your
manual transmission in FIRST (1)). But do not
shift the transfer case to the NEUTRAL (N)
position. Leave the transfer case in the

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), or with the clutch pedal depressed
in a manual shift. This is called “free-wheeling.”
Your brakes will have to do all the work and could
overheat and fade.

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.
Apply the parking brake.
D Shift to PARK (P) (or to NEUTRAL (N) with the
manual transmission) and, while still braking, restart
the engine.
D Shift back to a low gear, release the parking brake,
and drive straight down.
D If the engine won’t start, get out and get help.
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.
4-26
I
nf
or
mat
i
onPr
ovi
dedby:
yellowblue
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.
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.
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.

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.
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.
4-28
I
nf
or
mat
i
onPr
ovi
dedby:
yellowblue
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.
Find out how deep the water is before you drive through
it. If it’s deep enough to cover your wheel hubs, axles or
exhaust pipe, don’t try it -- you probably won’t get
through. Also, water that deep can damage your axle
and other vehicle parts.
If the water isn’t too deep, then drive through it slowly.
At fast speeds, water splashes on your ignition system
and your vehicle can stall. Stalling can also occur if you
get your tailpipe under water. And, as long as your
tailpipe is under water, you’ll never be able to start your
engine. When you go through water, remember that when
your brakes get wet, it may take you longer to stop.
CAUTION:
Driving through rushing water can be dangerous.
Deep water can sweep your vehicle downstream
and you and your passengers could drown. If it’s
only shallow water, it can still wash away the
ground from under your tires, and you could lose
traction and roll the vehicle over. Don’t drive
through rushing water.
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.

After Off-Road Driving
Driving at Night
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.
Night driving is more dangerous than day driving. One
reason is that some drivers are likely to be impaired -- by
alcohol or drugs, with night vision problems, or by fatigue.

Here are some tips on night driving.
D Drive defensively.
D Don’t drink and drive.
D Adjust your inside rearview mirror to reduce the
glare from headlamps behind you.
D Since you can’t see as well, you may need to
slow down and keep more space between you and
other vehicles.
D Slow down, especially on higher speed roads. Your
headlamps can light up only so much road ahead.
D In remote areas, watch for animals.
D If you’re tired, pull off the road in a safe place
and rest.
Night Vision
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.
You can be temporarily blinded by approaching
headlamps. It can take a second or two, or even several
seconds, for your eyes to readjust to the dark.
When you are faced with severe glare (as from a driver
who doesn’t lower the high beams, or a vehicle with
misaimed headlamps), slow down a little. Avoid staring
directly into the approaching headlamps.
Keep your windshield and all the glass on your vehicle
clean -- inside and out. Glare at night is made much
worse by dirt on the glass. Even the inside of the glass
can build up a film caused by dust. Dirty glass makes
lights dazzle and flash more than clean glass would,
making the pupils of your eyes contract repeatedly.
Remember that your headlamps light up far less of a
roadway when you are in a turn or curve. Keep your
eyes moving; that way, it’s easier to pick out dimly
lighted objects. Just as your headlamps should be
checked regularly for proper aim, so should your eyes
be examined regularly. Some drivers suffer from night
blindness -- the inability to see in dim light -- and
aren’t even aware of it.

Driving in Rain and on Wet Roads
Rain and wet roads can mean driving trouble. On a wet
road, you can’t stop, accelerate or turn as well because
your tire-to-road traction isn’t as good as on dry roads.
And, if your tires don’t have much tread left, you’ll get
even less traction. It’s always wise to go slower and be
cautious if rain starts to fall while you are driving. The
surface may get wet suddenly when your reflexes are
tuned for driving on dry pavement.
The heavier the rain, the harder it is to see. Even if your
windshield wiper blades are in good shape, a heavy rain
can make it harder to see road signs and traffic signals,
pavement markings, the edge of the road and even
people walking.
It’s wise to keep your wiping equipment in good shape
and keep your windshield washer tank filled with
washer fluid. Replace your windshield wiper inserts
when they show signs of streaking or missing areas on
the windshield, or when strips of rubber start to separate
from the inserts.

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.
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.

Hydroplaning
Driving Through Deep Standing Water
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.
NOTICE:
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.
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.
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.

Here are ways to increase your safety in city driving:
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.
I

ovi
dedby:

yellowblue
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.
Freeway Driving
Once you are on the freeway, adjust your speed to the
posted limit or to the prevailing rate if it’s slower. Stay
in the right lane unless you want to pass.
Before changing lanes, check your mirrors. Then use
your turn signal.
Just before you leave the lane, glance quickly over your
shoulder to make sure there isn’t another vehicle in your
“blind” spot.
Mile for mile, freeways (also called thruways, parkways,
expressways, turnpikes or superhighways) are the safest
of all roads. But they have their own special rules.
The most important advice on freeway driving is: Keep
up with traffic and keep to the right. Drive at the same
speed most of the other drivers are driving. Too-fast or
too-slow driving breaks a smooth traffic flow. Treat the
left lane on a freeway as a passing lane.
4-36
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.

Here are some things you can check before a trip:
Reduce your speed according to your speedometer, not

slower than you actually are.
D Windshield Washer Fluid: Is the reservoir full?

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.

CAUTION:
Coasting downhill in NEUTRAL (N) or with the

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.
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.

Winter Driving
Here are some tips for winter driving:
D Have your vehicle in good shape for winter.
D You may want to put winter emergency supplies in
your vehicle.
Include an ice scraper, a small brush or broom, a supply
of windshield washer fluid, a rag, some winter outer
clothing, a small shovel, a flashlight, a red cloth and
reflective warning triangles. And, if you will be driving
under severe conditions, include a small bag of sand, a
piece of old carpet or a couple of burlap bags to help
provide traction. Be sure you properly secure these
items in your vehicle.
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.
4-40
I
nf
or
mat
i
onPr
ovi
dedby:

Whatever the condition -- smooth ice, packed, blowing
or loose snow -- drive with caution.
Accelerate gently. Try not to break the fragile traction.
If you accelerate too fast, the drive wheels will spin and
polish the surface under the tires even more.
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.

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.

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.
If you have a diesel engine, you may have to run it at a
higher speed to get enough heat. Then, shut the engine
off and close the window almost all the way to preserve
the heat. Start the engine again and repeat this only
when you feel really uncomfortable from the cold. But
do it as little as possible. Preserve the fuel as long as you
can. To help keep warm, you can get out of the vehicle
and do some fairly vigorous exercises every half hour or
so until help comes.

Recreational Vehicle Towing
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 replace 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.

Use the following procedure to correctly tow your
vehicle on all four wheels:
Four-Wheel-Drive Vehicles
1. Firmly set the parking brake.
CAUTION:
Shifting the transfer case into NEUTRAL (N) can
cause your vehicle to roll even if the transmission
is in PARK (P), for an automatic transmission, or
if your vehicle is in gear, for a manual
transmission. You or others could be injured.
Make sure the parking brake is firmly set before
you shift the transfer case into NEUTRAL (N).
2. Shift an automatic transmission to PARK (P),
or a manual transmission to FIRST (1).
3. Securely attach the vehicle being towed to the
tow vehicle.
4. Shift the transfer case to NEUTRAL (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.

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.
Loading Your Vehicle
Never exceed the GVWR for your vehicle, or the
GAWR for either the front or rear axle.
The Certification/Tire label also contains information
about your Front Axle Reserve Capacity. See “Front
Axle Reserve Capacity” later in this section.
And, if you do have a heavy load, you should spread
it out.
The Certification/Tire label is found on the rear edge of
the driver’s door.
CAUTION:
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.

In the case of a sudden stop or collision, things
carried in the bed of your truck could shift
forward and come into the passenger area,
injuring you and others. If you put things in the

NOTICE: (Continued)
NOTICE:
Some vehicles may be equipped with RPO VYU
(snow plow prep package). With this option, the
payload your vehicle can carry is reduced when a
snow plow is installed. Your vehicle can be
damaged if either the front or rear axle ratings,
or the GVW are exceeded.
As a general guideline, with a 650 lb. (295 kg)
snow plow, the weight of the occupants and cargo
must not exceed 300 lb. (135 kg). However, this
may depend on the vehicle’s option content.
Therefore, to help avoid vehicle damage:
D Make sure the weight on the front and
rear axles does not exceed their respective
axle ratings.

See your dealer for advice and information
about using a snow plow on your vehicle.
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.
4-47
yellowblue
Your warranty does not cover parts or components that
fail because of overloading.
This 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.
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.

Front Axle Reserve Capacity
This is the difference between your front GAWR and the
front axle weight of your truck with full fuel and
passengers. It is the amount of weight you can add to
your front axle before reaching your front GAWR.
In order to calculate the amount of weight any
front accessory is adding to the front axle, use the
following formula.
The front axle reserve
capacity for your vehicle
can be found in the lower
right hand corner of the
tire/certification label, as
shown in this example.
(W x (A+W.B.)) / W.B.= Weight the accessory is adding
to the front axle
Where:
W= Weight of added accessory
A= Distance that the accessory is
in front of the front axle
W.B.= Vehicle Wheelbase
I

or
mat
i
onPr
ovi
dedby:
4-49
yellowblue
For example, adding a 700 lb. ( 318 kg) snow plow
adds more than 700 lb. ( 318 kg) to the front axle.
Using the formula, if the snow plow is 4 ft. (122 cm)
in front of the front axle and the wheel base is
10 ft. (305 cm), then:
W= 700 lb. ( 318 kg), A= 4 ft. (122 cm) and W.B.=
10 ft. (305 cm)
(W x (A+W.B.)) / W.B. = (700 x (4ft. + 10 ft.)) /
10 ft. = 980 lbs.
So, if your truck’s front axle reserve capacity is more
than 980 lbs. (445 kg), you could add this snow plow
without exceeding the front GAWR.
You can add heavier equipment on the front of the
vehicle if you compensate for it by carrying fewer
passengers, less cargo or by positioning cargo more
towards the rear. This has the effect of reducing the load
on the front. However, the front GAWR, rear GAWR
and the GVWR must never be exceeded.
Total Vehicle Reserve Capacity
This is the difference between your GVWR and the
weight of your truck with full fuel and passengers. It is
the amount of weight you can add to your vehicle before
reaching your GVWR.
The reserve capacity numbers are intended as a guide
when selecting the amount of equipment or cargo your
truck can carry. If you are unsure of your truck’s front,
rear or total weight, go to a weigh station and weigh
your vehicle. Your dealer can help you with this.
Truck-Camper Loading Information
This label is inside your glove box. It will tell you if
your vehicle can carry a slide-in camper, how much of a
load your vehicle can carry, and how to correctly spread
out your load. Also, it will help you match the right
slide-in camper to your vehicle.
When you carry a slide-in camper, the total cargo load
of your vehicle is the weight of the camper, plus
D everything else added to the camper after it left

The Cargo Weight Rating (CWR) is the maximum
weight of the load your vehicle can carry. It doesn’t
include the weight of the people inside. But, you can
figure about 150 lbs. (68 kg) for each seat.
Here is an example of proper truck and camper match:
The total cargo load must not be more than your
vehicle’s CWR.
Refer to the Truck-Camper Loading Information label in
glove box for dimensions A and B as shown in the
following illustration.
A. Camper Center of Gravity
B. Recommended Center of Gravity Location Zone
The camper’s center of gravity should fall within the
center of gravity zone for your vehicle’s cargo load.
Use the rear edge of the load floor for measurement
purposes. The recommended location for the cargo center
of gravity is at point C for the CWR. It is the point where
the mass of a body is concentrated and, if suspended at
that point, would balance the front and rear.
You must weigh any accessories or other equipment that
you add to your vehicle. Then, subtract this extra weight
from the CWR. This extra weight may shorten the
center of gravity zone of your vehicle. Your dealer can
help you with this.
If your slide-in camper and its load weighs less than the
CWR, the center of gravity zone for your vehicle may
be larger.

Your dealer can help you make a good vehicle-camper
match. He’ll also help you determine your CWR.
After you’ve loaded your vehicle and camper, drive to a
weigh station and weigh the front and rear wheels
separately. This will tell you the loads on your axles.
The loads on the front and rear axles shouldn’t be more
than either of the GAWRs. The total of the axle loads
should not be more than the GVWR.
Open your driver’s door and look at the Certification/Tire
label to find out your GAWR and GVWR.
If you’ve gone over your weight ratings, move or take
out some things until all the weight falls below the
ratings. Of course, you should always tie down any
loose items when you load your vehicle or camper.
When you install and load your slide-in camper, check
the manufacturer’s instructions.
If you want more information on curb weights, cargo
weights, Cargo Weight Rating and the correct center of
gravity zone for your vehicle, your dealer can help you.
Just ask for a copy of “Consumer Information,
Truck-Camper Loading.”

Trailer Recommendations
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.
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.

Pickup Conversion to Chassis Cab
Towing a Trailer
General Motors is aware that some vehicle owners may
consider having the pickup box removed and a
commercial or recreational body installed. Before you
do so, first contact the GM Customer Assistance Office
for your area for information on such conversions
specific to this vehicle. (See the “Warranty and Owner
Assistance” booklet for Customer Assistance Office.)
Owners should be aware that, as manufactured, there are
differences between a chassis cab and a pickup with the
box removed which may affect vehicle safety. The
components necessary to adapt a pickup to permit its
safe use with a specialized body should be installed by a
body builder in accordance with the information
available from the Customer Assistance Office.
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.
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

Your vehicle can tow a trailer. 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.
4-54
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 If you have an automatic transmission, 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).
See “Tow/Haul Mode” in the Index. 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).
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 (If Equipped)
Tow/haul is a feature on automatic transmission
equipped vehicles 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.
Automatic transmission equipped vehicles are provided
with a button at the end of the shift lever which when
pressed enables tow/haul. 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
in stop and go traffic.
D When pulling a heavy trailer or a large or heavy load
in busy parking lots where improved low speed
control of the vehicle is desired.
Operating the vehicle in tow/haul when lightly loaded or
with no trailer at all will not cause damage. However,
there is no benefit to the selection of tow/haul when the
vehicle is unloaded. Such a selection when unloaded
may result in unpleasant engine and transmission
driving characteristics and reduced fuel economy.
Tow/haul is recommended only when pulling a heavy
trailer or a large or heavy load.

Weight of the Trailer 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.

Hitches
It’s important to have the correct hitch equipment.
Crosswinds, large trucks going by and rough roads are a
few reasons why you’ll need the right hitch. Here are
some rules to follow:
D If you use a step-bumper hitch, your bumper could
be damaged in sharp turns. Make sure you have
ample room when turning to avoid contact between
the trailer and the bumper.
D If you’ll be pulling a trailer that, when loaded, will
weigh more than 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.
Safety Chains
You should always attach chains between your vehicle
and your trailer. Cross the safety chains under the tongue
of the trailer to help prevent the tongue from contacting
the road if it becomes separated from the hitch.
Instructions about safety chains may be provided by the
hitch manufacturer or by the trailer manufacturer. For
trailers up to 5,000 lbs. (2 270 kg) you may attach the
safety chains to the attaching points on the bumper. For
4-60
heavier trailers, follow the trailer or hitch manufacturer’s
recommendation for attaching safety chains. Always
leave just enough slack so you can turn with your rig.
Never allow safety chains to drag on the ground.
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 inch (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
Following Distance
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.
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.
Before you start, check the trailer hitch and platform
(and attachments), safety chains, electrical connector,
lamps, tires and mirror adjustment. If the trailer has
electric brakes, start your vehicle and trailer moving and
then apply the trailer brake controller by hand to be sure
the brakes are working. This lets you check your
electrical connection at the same time.
During your trip, check occasionally to be sure that the
load is secure, and that the lamps and any trailer brakes
are still working.
Passing
You’ll need more passing distance up ahead when
you’re towing a trailer. And, because you’re a good deal
longer, you’ll need to go much farther beyond the
passed vehicle before you can return to your lane.
Backing Up
Hold the bottom of the steering wheel with one hand.
Then, to move the trailer to the left, just move that hand
to the left. To move the trailer to the right, move your
hand to the right. Always back up slowly and, if
possible, have someone guide you.
While towing a trailer or when exposed to long periods
of sunshine, the floor of the truck bed may become very
warm. Avoid putting items in the truck bed that might be
affected by high ambient temperatures.

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.
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.
Driving On Grades
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.
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.
If you have an automatic transmission, 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.
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).

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) (or the
manual transmission out of gear and the parking brake
applied) for a few minutes before turning the engine off.
If you do get the overheat warning, see “Engine
Overheating” in the Index.
Parking on Hills
But if you ever have to park your rig on a hill, here’s
how to do it:
1. Apply your regular brakes, but don’t shift into
PARK (P) yet for an automatic transmission, or into
gear for a manual transmission.
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) for an
automatic transmission, or REVERSE (R) for a
manual transmission.
5. If you have a four-wheel-drive vehicle, be sure
the transfer case is in a drive gear and not in
NEUTRAL (N).
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.
6. Release the regular brakes.
I

ovi
dedby:
4-63
yellowblue
CAUTION:
It can be dangerous to get out of your vehicle if
the shift lever is not fully in PARK (P) with the
parking brake firmly set. Your vehicle can roll.
If you have left the engine running, the vehicle
can move suddenly. You or others could be
injured. To be sure your vehicle won’t move, even
when you’re on fairly level ground, use the steps
that follow.
Always put the shift lever fully in PARK (P) with
the parking brake firmly set.
If the transfer case on four-wheel drive vehicles is
in NEUTRAL (N), 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 (N).
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, 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.

300 feet (100 m) behind your vehicle.
Ignoring these steps could result in costly
damage to your vehicle that wouldn’t be
covered by your warranty.
The ACDelco FreedomR 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.
Jump Starting
If your battery (or batteries) have 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.
1. Check the other vehicle. It must have a 12-volt
battery with a negative ground system.

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.
NOTICE:
If you leave your radio on, it could be badly
damaged. The repairs wouldn’t be covered by
your warranty.
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) or a manual transmission
in NEUTRAL (N). 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!
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 engine accessory
drive bracket. To uncover the remote positive (+)
terminal, open the red plastic cover.
On all V8 gasoline and diesel engines, the remote
negative (-) terminal is located on the engine
accessory drive bracket. This is marked “GND”on
V8 gasoline engines. On V6 engines, the remote
negative (-) terminal is located on a tab attached to
the engine accessory drive bracket where it is
marked “GND”.
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 batteries have enough water. You
don’t need to add water to the ACDelco
FreedomR battery (or batteries) installed in
every new GM vehicle. But if a battery has filler
caps, be sure the right amount of fluid is there. If
it is low, add water to take care of that first. If
you don’t, explosive gas could be present.
Battery fluid contains acid that can burn you.
Don’t get it on you. If you accidentally get it in
your eyes or on your skin, flush the place with
water and get medical help immediately.

Overheated Engine Protection Operating
Mode (V8 Gasoline Engines Only)
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.

If Steam Is Coming From Your Engine
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. 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.

If you get the overheat warning with no sign of steam,
try this for a minute or so:
NOTICE:
1. If you have an air conditioner and it’s on, turn it off.
If your engine catches fire because you keep
driving with no coolant, your vehicle can be
badly damaged. The costly repairs would not be
covered by your warranty. See “Overheated
Engine Protection Operating Mode” in the Index.
If No Steam Is Coming From Your Engine
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:

Climb a long hill on a hot day.
Stop after high-speed driving.
Idle for long periods in traffic.
Tow a trailer. See “Driving on Grades” in the Index.
2. Turn on your heater to full hot at the highest fan
speed and open the window as necessary.
3. If you’re in a traffic jam, shift to NEUTRAL (N);
otherwise, shift to the highest gear while
driving -- DRIVE (D) for automatic transmissions.
If you no longer have the overheat warning, you can
drive. Just to be safe, drive slower for about 10 minutes.
If the warning doesn’t come back on, you can
drive normally.
If the warning continues, pull over, stop, and park your
vehicle right away.
If there’s still no sign of steam, push down the
accelerator until the engine speed is about twice as fast
as normal idle speed for at least three minutes while
you’re parked. If you still have the warning, turn off the
engine and get everyone out of the vehicle until it cools
down. Also, see “Overheated Engine Protection
Operating Mode” listed previously in this section.
You may decide not to lift the hood but to get service
help right away.

Cooling System (Gasoline Engine)
The coolant level

the FILL COLD mark.
When you decide it’s safe to lift the hood, here’s what
you’ll see:
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.

NOTICE:
CAUTION:
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.
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.
NOTICE:
Engine damage from running your engine
without coolant isn’t covered by your warranty.
See “Overheated Engine Protection Operating
Mode” in the Index.
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 -- Gasoline Engines
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.

NOTICE:
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.

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. Then replace the pressure cap. Be sure the pressure
cap is hand-tight.
By this time, the coolant level inside the coolant
surge tank may be lower. If the level is lower, add

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.
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. If you have a four-wheel-drive vehicle,
be sure the transfer case is in a drive
gear -- not in NEUTRAL (N).
4. Turn off the engine.
5. Put the wheel blocks at the front and
rear of the tire farthest away from the
one being changed. That would be the
tire on the other side of the vehicle, at
the opposite end.
The following steps will tell you how to use the jack and
change a tire.

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.
For information about using tire chains on your vehicle,
see “Tire Chains” in the Index.
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.
Rocking Your Vehicle To Get It Out
First, turn your steering wheel left and right. That will clear
the area around your front wheels. If you have a four-wheel
drive vehicle, shift into 4HI. Then shift back and forth
between REVERSE (R) and a forward gear (or with a
manual transmission, between FIRST (1) or SECOND (2)
and REVERSE (R)), 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.

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 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.

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.
If your vehicle has a diesel engine, see “Diesel Fuel
Requirements and Fuel System” in the Diesel Engine
Supplement. For vehicles with gasoline engines, please
read this.
Use regular unleaded gasoline rated at 87 octane or
higher. It is recommended that the gasoline meet
specifications which have been 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. For more information,
write to: American Automobile Manufacturer’s
Association, 7430 Second Ave, Suite 300,
Detroit MI 48202.
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.
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

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.

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.
When you put the cap back on, turn it to the right

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:
6-14
I
nf
or
mat
i
onPr
ovi
dedby:
yellowblue
As shown in the chart, 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.
_
_
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.
Engine Oil Additives
Don’t add anything to your oil. Your dealer is ready to
advise if you think something should be added.
When to Change Engine Oil
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 Oil Life Monitor will indicate
that a change is necessary. The mileage between oil
changes will vary depending on how you drive your
vehicle -- usually between 3,000 miles (5 000 km) and
7,500 miles (12 500 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 7,500 miles (12 500 km) or 12 months
(whichever occurs first) without an oil change.
The system won’t detect dust in the oil. So, if you drive
in a dusty area, be sure to change your oil every
3,000 miles (5 000 km) or sooner. Remember to reset
the CHANGE ENGINE OIL message whenever the oil
is changed.

How to Reset the CHANGE ENGINE OIL Message
Engine Air Cleaner/Filter
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.
The air cleaner 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.
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.)
See “Owner Checks and Services” in the Index to
determine when to check the indicator.
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.

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.
To replace the passenger compartment air filter:
1. If your vehicle is equipped with a panel under the
center of the instrument panel, remove the bolts on it
to remove the panel. Because this operation can be a

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.

Checking Coolant (Gasoline Engine)
The coolant surge tank
is located on the
passenger’s side of the
engine compartment.
If your vehicle has a diesel engine, see “Checking
Coolant” in the Diesel Engine Supplement.
The vehicle must be on a level surface. When your
engine is cold, the coolant level should be at the
FILL COLD mark.
If the LOW COOLANT
message comes on, it
means you’re low on
engine coolant.
See “Low Coolant” in the Index.
Adding Coolant
If you need more coolant, add the proper DEX-COOLR
coolant mixture at the surge tank, but only when the
engine is cool.
CAUTION:
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.
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.

Power Steering Fluid
How to Check Power Steering Fluid
When the engine compartment is cool, wipe the cap and
the top of the reservoir clean, then unscrew the cap and
wipe the dipstick with a clean rag. Replace the cap and
completely tighten it. Then remove the cap again and
look at the fluid level on the dipstick.
The level should be at the FULL COLD mark. If
necessary, add only enough fluid to bring the level up to
the mark.
What to Use
To determine what kind of fluid to use, see
“Recommended Fluids and Lubricants” in the Index.
Always use the proper fluid. Failure to use the proper
fluid can cause leaks and damage hoses and seals.
When to Check Power Steering Fluid
It is not necessary to regularly check power steering
fluid unless you suspect there is a leak in the system or
you hear an unusual noise. A fluid loss in this system
could indicate a problem. Have the system inspected
and repaired.

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.

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.
Brakes
Brake Fluid
Your brake master cylinder
reservoir is here. It is filled
with DOT-3 brake fluid.
CAUTION:
If you have too much brake fluid, it can spill on the
engine. The fluid will burn if the engine is hot
enough. You or others could be burned, and your
vehicle could be damaged. Add brake fluid only
when work is done on the brake hydraulic system.
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.

Refer to the Maintenance Schedule to determine when to
check your brake fluid. See “Periodic Maintenance
Inspections” in the Index.

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.
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.
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.

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.
NOTICE:
Continuing to drive with worn-out brake pads
could result in costly brake repair.

Some driving conditions or climates may cause a brake
squeal when the brakes are first applied or lightly
applied. This does not mean something is wrong with
your brakes.
Properly torqued wheel nuts are necessary to help
prevent brake pulsation. When tires are rotated, inspect
brake pads for wear and evenly torque wheel nuts in the
proper sequence to GM specifications.
Brake linings should always be replaced as complete
axle sets.
See “Brake System Inspection” in Section 7 of this manual
under Part C “Periodic Maintenance Inspections.”
Brake Pedal Travel
See your dealer if the brake pedal does not return to
normal height, or if there is a rapid increase in pedal
travel. This could be a sign of brake trouble.
Brake Adjustment
Every time you make a brake stop, your disc brakes
adjust for wear.
Replacing Brake System Parts
The braking system on a vehicle is complex. Its many
parts have to be of top quality and work well together if
the vehicle is to have really good braking. Your vehicle
was designed and tested with top-quality GM brake
parts. When you replace parts of your braking
system -- for example, when your brake linings wear
down and you 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.
Battery
Your new vehicle comes with an ACDelco FreedomR
battery. When it’s time for a new battery, we recommend
an ACDelco Freedom battery. Get one that has the
replacement number shown on the original battery’s label.

the Index.
D Underinflated tires pose the same danger as
overloaded tires. The resulting accident
could cause serious injury. Check all tires
frequently to maintain the recommended
pressure. Tire pressure should be checked
when your tires are cold.
D Overinflated tires are more likely to be cut,
punctured or broken by a sudden impact -such as when you hit a pothole. Keep tires

vehicle has been sitting for at least three hours or driven
no more than 1 mile (1.6 km).
NOTICE:
Don’t let anyone tell you that underinflation or
overinflation is all right. It’s not. If your tires
don’t have enough air (underinflation), you can
get the following:
D Too much flexing
D Too much heat
D Tire overloading

D Rough ride
D Needless damage from road hazards.
When to Check
Check your tires once a month or more. Also, check the
tire pressure of the spare tire.
How to Check
Use a good quality pocket-type gage to check tire
pressure. You can’t tell if your tires are properly inflated
simply by looking at them. Radial tires may look
properly inflated even when they’re underinflated.
Be sure to put the valve caps back on the valve stems.

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.
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.
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.

only 1/16 inch (1.6 mm) or
less of tread remaining.
You need a new tire if any of the following statements
are true:
D You can see the indicators at three or more places
around the tire.
D You can see cord or fabric showing through the
tire’s rubber.
D The tread or sidewall is cracked, cut or snagged deep
enough to show cord or fabric.
D The tire has a bump, bulge or split.
D The tire has a puncture, cut or other damage that
can’t be repaired well because of the size or location
of the damage.

Buying New Tires
To find out what kind and size of tires you need, look at
the Certification/Tire label.
The tires installed on your vehicle when it was new had
a Tire Performance Criteria Specification (TPC Spec)
number on each tire’s sidewall. When you get new tires,
get ones with that same TPC Spec number. That way
your vehicle will continue to have tires that are designed
to give proper endurance, handling, speed rating,
traction, ride and other things during normal service on
your vehicle. If your tires have an all-season tread
design, the TPC number will be followed by an “MS”
(for mud and snow).
If you ever replace your tires with those not having a
TPC Spec number, make sure they are the same size,
load range, speed rating and construction type (bias,
bias-belted or radial) as your original tires.

CAUTION:
Mixing tires could cause you to lose control while
driving. If you mix tires of different sizes or types
(radial and bias-belted tires), the vehicle may not
handle properly, and you could have a crash.
Using tires of different sizes may also cause
damage to your vehicle. Be sure to use the same
size and type tires on all wheels.
CAUTION:
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
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.
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.
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.
6-50
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.
I

or
mat
i
onPr
ovi
dedby:
yellowblue
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.

Fabric Protection
Cleaning Leather
Your vehicle has upholstery and carpet fabric that has
been treated with Scotchgardt Fabric Protector, a 3M
product. It protects fabrics by repelling oil and water,
which are the carriers of most stains. Even with this
protection, you still need to clean your upholstery and
carpet often to keep it looking new.
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.
Further information on cleaning is available by calling
1-800-433-3296 (in Minnesota, 1-800-642-6167).
cleaners, furniture polish or shoe polish on leather.
Cleaning Vinyl
Use warm water and a clean cloth.
D Rub with a clean, damp cloth to remove dirt. You
may have to do it more than once.
D Things like tar, asphalt and shoe polish will stain if
you don’t get them off quickly. Use a clean cloth
and a vinyl/leather cleaner. See your dealer for
this product.
D For stubborn stains, use a leather cleaner. See your
dealer for this product.
D Never use oils, varnishes, solvent-based or abrasive
D Soiled or stained leather should be cleaned
immediately. If dirt is allowed to work into the
finish, it can harm the leather.
Cleaning the Top of the Instrument Panel
Use only mild soap and water to clean the top surfaces
of the instrument panel. Sprays containing silicones or
waxes may cause annoying reflections in the windshield
and even make it difficult to see through the windshield
under certain conditions.
Cleaning Interior Plastic Components
Use only a mild soap and water solution on a soft
cloth or sponge. Commercial cleaners may affect the
surface finish.

Care of Safety Belts
Cleaning the Outside of the
Windshield and Wiper Blades
Keep belts clean and dry.
CAUTION:
Do not bleach or dye safety belts. If you do, it
may severely weaken them. In a crash, they
might not be able to provide adequate protection.
Clean safety belts only with mild soap and
lukewarm water.
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.
If the windshield is not clear after using the windshield
washer, or if the wiper blade chatters when running,
wax, sap or other material may be on the blade
or windshield.
Clean the outside of the windshield with 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 lukewarm or cold water, a soft cloth and a vehicle
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.
6-58
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.

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 any wheels other than chrome-plated 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.
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.
6-60
Finish Damage
Any stone chips, fractures or deep scratches in the finish
should be repaired right away. Bare metal will corrode
quickly and may develop into a major repair expense.
Minor chips and scratches can be repaired with touch-up
materials available from your dealer or other service
outlets. Larger areas of finish damage can be corrected
in your dealer’s body and paint shop.

Underbody Maintenance
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.
This applies only to materials manufactured and sold by
General Motors. Bodies, body conversions or equipment
not made or sold by General Motors are not covered.

Electrical System
Windshield Wipers
Add-On Electrical Equipment
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.
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.
Power Windows and Other Power Options
Circuit breakers protect the power windows and other
power accessories. When the current load is too heavy,
the circuit breaker opens and closes, protecting the
circuit until the problem is fixed or goes away.
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.

Instrument Panel Fuse Block
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.
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.
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.
You can remove fuses with a fuse extractor. The fuse
extractor 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.
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.

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 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” provides a place
for you to record the maintenance performed on your
vehicle. Whenever any maintenance is performed, be
sure to write it down in this part. This will help you
determine when your next maintenance should be done.
In addition, it is a good idea to keep your maintenance
receipts. They may be needed to qualify your vehicle for
warranty repairs.
If you are skilled enough to do some work on your
vehicle, you will probably want to get the service
information. See “Service and Owner Publications” in
the Index.

Part A: Scheduled Maintenance
Services
Using Your Maintenance Schedule
We at General Motors want to help you keep your
vehicle in good working condition. But we don’t know
exactly how you’ll drive it. You may drive very short
distances only a few times a week. Or you may drive
long distances all the time in very hot, dusty weather.
You may use your vehicle in making deliveries. Or
you may drive it to work, to do errands or in many
other ways.
Because of all the different ways people use their
vehicles, maintenance needs vary. You may need more
frequent checks and replacements. So please read the
following and note how you drive. If you have any
questions on how to keep your vehicle in good
condition, see your dealer.
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.
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.

Scheduled Maintenance -- Gasoline Engines
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) and
200,000 miles (332 000 km) should be performed at the
same intervals after 150,000 miles (240 000 km) and
200,000 miles (332 000 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.
# 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.

Scheduled Maintenance -- Gasoline Engines
* Your vehicle has an Engine Oil Life Monitor. This
monitor will show you when to change the engine oil
and filter -- usually between 3,000 miles (5 000 km)
and 7,500 miles (12 500 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 7,500 miles (12 500 km) or 12 months
without an oil and filter change.
7-6
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 Monitor whenever the oil is changed. For
more information, see “Change Engine Oil Message” in
the Index.
+ 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.

Windshield Washer Fluid Level Check
Check the windshield washer fluid level in the
windshield washer tank and add the proper fluid if
necessary. See “Windshield Washer Fluid” in the Index
for further details.
At Least Once a Month
It is important for you or a service station attendant to
perform these underhood checks at each fuel fill.
Tire Inflation Check
Engine Oil Level Check
Make sure tires are inflated to the correct pressures.
See “Tires” in the Index for further details.
Check the engine oil level and add the proper oil if

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.
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 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.)

2. Firmly apply both the parking brake (see “Parking
Brake” in the Index if necessary) and the regular brake.
1. Before you start, be sure you have enough room
around the vehicle. It should be parked on a
level surface.
NOTE: Do not use the accelerator pedal, and be
ready to turn off the engine immediately if it starts.
2. Firmly apply the parking brake
(see “Parking Brake” in the Index if necessary).
3. On automatic transmission vehicles, 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.
On manual transmission vehicles, put the shift lever
in NEUTRAL (N), push the clutch down halfway
and try to start the engine. The starter should work
only when the clutch is pushed down all the way to

Exhaust System Inspection
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.
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,

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
I
nf
or
mat
i
onPr
ovi
dedby:
yellowblue
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 must 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).

with any other venue for relief available to you.
You may contact the BBB using the toll-free telephone

Courtesy Transportation
Chevrolet has always exemplified quality and value in
its offering of motor vehicles. To enhance your
ownership experience, we and our participating
dealerships 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 it is
determined that your vehicle cannot be scheduled into
the service department immediately and is still
operative, you are encouraged to drive the vehicle until
scheduling can be accomplished.
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 dealerships 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.
I
nf
or
mat
i
onPr
ovi
dedby:

Courtesy Rental Vehicle
When your vehicle is unavailable due to overnight
warranty repairs, your dealer may arrange to provide
you with a courtesy rental vehicle or reimburse you for a
rental vehicle you obtained, at actual cost, up to a
maximum of $30.00 per day supported by receipts. This
requires that you sign and complete a rental agreement
and meet state, local and rental vehicle provider
requirements. Requirements vary and may include
minimum age requirements, insurance coverage, credit
card, etc. You are responsible for fuel usage charges and
may also be responsible for taxes, levies, usage fees,
excessive mileage or rental usage beyond the
completion of the repair.
Generally it is not possible to provide a like-vehicle as a
courtesy rental.
Additional Program Information
Courtesy Transportation is available during the
Bumper-to-Bumper warranty coverage period,
but it is not part of the New Vehicle Limited Warranty.
A separate booklet entitled “Warranty and Owner
Assistance Information” furnished with each new
vehicle provides detailed warranty coverage information.
Courtesy Transportation is available only at
participating dealerships and all program options, such
as shuttle service, may not be available at every dealer.
Please contact your dealer for specific information about
availability. All Courtesy Transportation arrangements
will be administered by appropriate dealer personnel.
Canadian Vehicles: For warranty repairs during the
Complete Vehicle Coverage period of the General
Motors of Canada New Vehicle Limited Warranty,
alternative transportation may be available under the
Courtesy Transportation Program. Please consult your
dealer for details.
General Motors reserves the right to unilaterally modify,
change or discontinue Courtesy Transportation at any time
and to resolve all questions of claim eligibility pursuant to the
terms and conditions described herein at its sole discretion.
General Motors and participating dealerships reserve the
right to deny a rental vehicle to anyone not possessing a
valid motor vehicle operators license in their name,
anyone who is under the influence of alcohol or drugs, or
anyone whose mental or physical abilities are impaired so
as to be unable to operate a motor vehicle safely.
Warranty Information
Your vehicle comes with a separate warranty booklet
that contains detailed warranty information.

REPORTING SAFETY DEFECTS TO
THE CANADIAN 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.
If you live in Canada, and you believe that your vehicle
has a safety defect, you should immediately notify
Transport Canada, in addition to notifying General
Motors of Canada Limited. You may write to:
Transport Canada
330 Sparks Street
Tower C
Ottawa, Ontario K1A 0N5
To contact NHTSA, you may either call the Auto Safety
Hotline toll-free at 1-800-424-9393 (or 366-0123 in the
