Fuel Gage
When the ignition is on, the fuel gage tells you
about how much fuel you have remaining.
Here are four things that some owners ask about.
None of these show a problem with your fuel gage:
At the gas station, the gas pump shuts off
before the gage reads full.
It takes a little more or less fuel to ll up than
the gage indicated. For example, the gage
may have indicated the tank was half full, but it
actually took a little more or less than half the
tank’s capacity to ll the tank.
The gage moves a little when you turn a corner
or speed up.
The gage doesn’t go back to empty when you
turn off the ignition.
Low Fuel Warning Light
The light next to the fuel gage will come on briey
when you are starting the engine.
This light comes on when the fuel tank is low on
fuel. To turn it off, add fuel to the fuel tank.
Check Gas Cap Light
If your vehicle has this
light, it will come on if
your gas cap is not
securely fastened.

Notice:Before adding any sound equipment
to your vehicle, such as an audio system,
CD player, CB radio, mobile telephone,
or two-way radio, make sure that it can be
added by checking with your dealer/retailer.
Also, check federal rules covering mobile radio
and telephone units. If sound equipment can
be added, it is very important to do it properly.
Added sound equipment may interfere with
the operation of your vehicle’s engine, radio,
or other systems, and even damage them.
Your vehicle’s systems may interfere with
the operation of sound equipment that
has been added.
Notice:The chime signals related to safety
belts, parking brake, and other functions
of your vehicle operate through the radio/
entertainment system. If that equipment
is replaced or additional equipment is added
to your vehicle, the chimes may not work.
Make sure that replacement or additional
equipment is compatible with your vehicle
before installing it. SeeAccessories and
Modifications on page 386.Your vehicle may have a feature called Retained
Accessory Power (RAP). With RAP, the audio
system can be played even after the ignition is

If you keep pace with the traffic and allow realistic
following distances, you will eliminate a lot of
unnecessary braking. That means better braking
and longer brake life.
If your vehicle’s engine ever stops while you are
driving, brake normally but do not pump the
brakes. If you do, the pedal may get harder to
push down. If the 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.
Adding non-GM accessories can affect your
vehicle’s performance. SeeAccessories and
Modications on page 386.Anti-Lock Brake System (ABS)
Your vehicle has the Anti-Lock Brake
System (ABS), an advanced electronic braking
system that will help prevent a braking skid.
When you start the engine and begin to drive
away, ABS will check itself. You might hear
a momentary motor or clicking noise while this
test is going on. This is normal.
If there is a problem
with ABS, this warning
light will stay on.
SeeAnti-Lock Brake
System Warning
Light on page 209.
Along with ABS, your vehicle has a Dynamic Rear
Proportioning (DRP) system. If there is a DRP
problem, both the brake and ABS warning lights
will come on accompanied by a 10-second
chime. The lights and chime will come on each
time the ignition is turned on until the problem is
repaired. See your dealer/retailer for service.
311

Remember: ABS does not 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 will not have
time to apply the brakes if that vehicle suddenly
slows or stops. Always leave enough room up
ahead to stop, even though you have ABS.
Using ABS
Do not pump the brakes. Just hold the brake
pedal down rmly and let anti-lock work for you.
You might feel the brakes vibrate or notice
some noise, but this is normal.
Braking in Emergencies
With ABS, you can steer and brake at the same
time. In many emergencies, steering can help you
more than even the very best braking.
Locking Rear Axle
If your vehicle has this feature, your locking rear
axle can give you additional traction on snow, mud,
ice, sand or gravel. It works like a standard axle
most of the time, but when one of the rear wheels
has no traction and the other does, this feature will
allow the wheel with traction to move the vehicle.
StabiliTrak®System
Your vehicle is equipped with StabiliTrak®,
Electronic Stability Control (ESC) which combines
antilock brake, traction and stability control
systems and helps the driver maintain directional
control of the vehicle in most driving conditions.
Traction control activates when the controller
senses wheel spin. StabiliTrak
®will selectively
apply the brakes and reduce engine torque to
help regain traction.
Stability control activates when the controller
senses a discrepancy between your intended
path and the direction the vehicle is travelling.
StabiliTrak
®selectively applies braking pressure
at any one of the vehicle’s brakes to help guide the
vehicle in the direction which you are steering.
When you rst start your vehicle and begin to drive
away, the system performs several diagnostic
checks to insure there are no problems. You may
hear or feel the system working. This is normal
and does not mean there is a problem with
your vehicle. If driving conditions delay system
initialization, the STABILITRAK NOT READY
message may be displayed. If this is the case,
your vehicle does not need servicing.
313

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 want to slow down and adjust your
driving to these conditions. It is important to slow
down on slippery surfaces because stopping
distance is longer and vehicle control more limited.
While driving on a surface with reduced traction, try
your best to avoid sudden steering, acceleration, or
braking, including reducing vehicle speed by
shifting to a lower gear. Any sudden changes could
cause the tires to slide. You might not realize the
surface is slippery until your vehicle is skidding.
Learn to recognize warning clues — such as
enough water, ice, or packed snow on the road to
make a mirrored surface — and slow down when
you have any doubt.
Remember: Any Anti-Lock Brake System (ABS)
helps avoid only the braking skid.Competitive Driving
See your warranty book before using your vehicle
for competitive driving. After reviewing your
warranty book, please see the GM Performance
Parts website or catalog for parts and equipment
required for competitive driving.
Notice:If you use your vehicle for competitive
driving, the engine may use more oil than it
would with normal use. Low oil levels can
damage the engine. Be sure to check the oil
level often during competitive driving and keep
the level at or near the upper mark that
shows the proper operating range on the
engine oil dipstick. For information on how to
add oil, seeEngine Oil on page 402.
Off-Road Driving (Except SS)
This off-road guide is for vehicles that have
four-wheel drive. Also, seeBraking on page 310.
If your vehicle does not have four-wheel drive,
you should not drive off-road unless you are
on a level, solid surface.
323

Driving in Water
{CAUTION:
Driving through rushing water can be
dangerous. Deep water can sweep your
vehicle downstream and you and your
passengers could drown. If it is only
shallow water, it can still wash away the
ground from under your tires, and you
could lose traction and roll the vehicle
over. Do not drive through rushing water.
Heavy rain can mean ash ooding, and ood
waters demand extreme caution.
Find out how deep the water is before you drive
through it. If it is deep enough to cover the
wheel hubs, axles, or exhaust pipe, do not try
it — you probably will not get through. Also, water
that deep can damage the axle and other
vehicle parts.If the water is not too deep, drive slowly through it.
At faster speeds, water splashes on the ignition
system and your vehicle can stall. Stalling can also
occur if you get the tailpipe under water. And,
as long as the tailpipe is under water, you
will never be able to start the engine. When you
go through water, remember that when the brakes
get wet, it may take you longer to stop.
SeeDriving in Rain and on Wet Roads on page 340
for more information on driving through water.
After Off-Road Driving
Remove any brush or debris that has collected on
the underbody, chassis, or under the hood.
These accumulations can be a re 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.
