When the ignition is on, the brake
system warning light comes on
when the parking brake is set. See
Parking Brake on page 2-28for
more information. The light stays on
if the parking brake does not
release fully. If it stays on after the
parking brake is fully released, it
means there is a brake problem.If the light comes on while driving,
pull off the road and stop. The brake
pedal might be harder to push, or
it might go closer to the oor. It can
take longer to stop. If the light is
still on, have the vehicle towed for
service. SeeTowing Your Vehicle
on page 4-40.
{CAUTION
The brake system might not be
working properly if the brake
system warning light is on. Driving
with the brake system warning
light on can lead to a crash. If the
light is still on after the vehicle
has been pulled off the road and
carefully stopped, have the
vehicle towed for service.
Antilock Brake System
(ABS) Warning Light
For vehicles with the Antilock Brake
System (ABS), this light comes
on briey when the engine is started.
If it does not, have the vehicle
serviced by your dealer/retailer. If

the indicator light will then go off.
If the ABS light stays on, turn
the ignition off. If the light comes on
while driving, stop as soon as it
is safely possible and turn the
ignition off. Then start the engine
again to reset the system. If the ABS
light stays on, or comes on again
while driving, the vehicle needs

An arrow on the fuel gage indicates
the side of the vehicle the fuel
door is on.
Here are three things that can
happen but do not indicate a
problem with the 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
turning a corner or speeding up.
When the fuel in the fuel tank is low,
a LOW FUEL message displays
on the Driver Information
Center (DIC). SeeDIC Warnings
and Messages on page 3-37
for more information.

Braking in Emergencies
ABS allows the driver to steer
and brake at the same time. In many
emergencies, steering can help
more than even the very best
braking.
Brake Assist
This vehicle has a Brake Assist
feature designed to assist the driver
in stopping or decreasing vehicle
speed in emergency driving
conditions. This feature uses the
stability system hydraulic brake
control module to supplement the
power brake system under
conditions where the driver has
quickly and forcefully applied
the brake pedal in an attempt to
quickly stop or slow down the
vehicle. The stability system
hydraulic brake control module
increases brake pressure at each
corner of the vehicle until the
ABS activates. Minor brake pedal
pulsations or pedal movement
during this time is normal and the
driver should continue to applythe brake pedal as the driving
situation dictates The Brake Assist
feature will automatically disengage
when the brake pedal is released
or brake pedal pressure is quickly
decreased.
StabiliTrak®System
The vehicle has a vehicle stability
enhancement system called
StabiliTrak. It is an advanced
computer controlled system that
assists the driver with directional
control of the vehicle in difficult
driving conditions.
StabiliTrak activates when the
computer senses a discrepancy
between the intended path and the
direction the vehicle is actually
traveling. StabiliTrak selectively
applies braking pressure at any one
of the vehicle’s brakes to assist
the driver with keeping the vehicle
on the intended path.
When the vehicle is started and
begins to move, the system
performs several diagnostic checksto insure there are no problems.
The system may be heard or
felt while it is working. This is normal
and does not mean there is a
problem with the vehicle.
If cruise control is being used when
StabiliTrak activates, the cruise
control automatically disengages.
The cruise control can be
re-engaged when road conditions
allow. SeeCruise Control on
page 3-9.
If there is a problem detected with
StabiliTrak, a SERVICE STAB
SYS message displays on the Driver
Information Center (DIC). See
DIC Warnings and Messages on
page 3-37for more information.
When this message is displayed, the
system is not working. Adjust your
driving accordingly.
StabiliTrak comes on automatically
whenever the vehicle is started
and resets itself at each ignition
cycle. However, when the transfer
case is placed in Four-Wheel-Low
Lock mode, StabiliTrak is

GM6094M
Use only an oil that meets
GM Standard GM6094M.
SAE 5W-30
SAE 5W-30 is best for the
vehicle. These numbers on an
oil container show its viscosity,
or thickness. Do not use
other viscosity oils such as
SAE 20W-50.
American Petroleum Institute
(API) starburst symbol
Oils meeting these requirements
should have the starburst symbol
on the container. This symbol
indicates that the oil has been
certied by the American
Petroleum Institute (API).Notice:Use only engine oil
identied as meeting GM
Standard GM6094M and showing
the American Petroleum
Institute Certied For Gasoline
Engines starburst symbol. Failure
to use the recommended oil
can result in engine damage not
covered by the vehicle warranty.
Cold Temperature Operation
If in an area of extreme cold, where
the temperature falls below−20°F
(−29°C), use either an SAE 5W-30
synthetic oil or an SAE 0W-30
engine oil. Both provide easier cold
starting for the engine at extremely
low temperatures. Always use
an oil that meets the required
specication, GM6094M. See “What
Kind of Engine Oil to Use” for
more information.
Engine Oil Additives / Engine
Oil Flushes
Do not add anything to the oil.
The recommended oils with
the starburst symbol that meet
GM Standard GM6094M are all that
is needed for good performance
and engine protection.
Engine oil system ushes are not
recommended and could cause
engine damage not covered by the
vehicle warranty.
Engine Oil Life System
When to Change Engine Oil
This vehicle has a computer system
that indicates when to change the
engine oil and lter. This is based on
engine revolutions and engine
temperature, and not on mileage.
Based on driving conditions,
the mileage at which an oil change
is indicated can vary considerably.
For the oil life system to work
properly, the system must be reset
every time the oil is changed.
