suddenly slows or stops. Always
leave enough room up ahead to
stop, even with ABS.
Using ABS
Do not pump the brakes. Just hold
the brake pedal down firmly and let
ABS work. You might hear the ABS
pump or motor operating and feel
the brake pedal pulsate, but this is
normal.
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.
Parking Brake
The parking brake pedal is located
to the left of the brake pedal, near
the driver door.
To set the parking brake, hold the
brake pedal down, then push the
parking brake pedal down to its
fully-applied position.A chime will activate and the brake
warning light, located on the
instrument panel, will flash when the
parking brake is applied and the
vehicle is moving at least 5 km/h
(3 mph) for at least three seconds.
The chime will deactivate and the
light will turn off when the parking
brake is set and the vehicle is
moving below 5 km/h (3 mph).
See
Brake System Warning Light on
page 5‑15.

To release the parking brake,
hold the regular brake pedal down.
Pull the bottom edge of the lever,
located above the parking brake
pedal, with the parking brake
symbol, directly rearward to
release the parking brake.
If the ignition is on when the parking
brake is released, the brake system
warning light will go off.
Notice:Driving with the parking
brake on can overheat the brake
system and cause premature
wear or damage to brake system
parts. Make sure that the parking
brake is fully released and the
brake warning light is off before
driving.
If you are towing a trailer and are
parking on any hill, see Driving
Characteristics and Towing Tips on
page 9‑54.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 pulsation or
pedal movement during this time is
normal and the driver should
continue to apply the 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.

Ride Control Systems
Traction Control
System (TCS)
The Traction Control System (TCS)
is part of StabiliTrak. TCS limits
wheel slip which is especially useful
in slippery road conditions. The
system operates only if it senses
that any of the wheels are spinning
or beginning to lose traction. When
this happens, TCS applies the
brakes to limit wheel spin and also
reduces engine power. 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.
Notice:If the wheel(s) of one axle
is allowed to spin excessively
while the StabiliTrak
®, ABS, brake
warning lights, and any relevant
DIC messages are displayed, the
transfer case could be damaged.
The repairs would not be covered
by the vehicle warranty. Reduce
engine power and do not spin the wheel(s) excessively while these
lights and messages are
displayed.
TCS can operate on dry roads
under some conditions. When this
happens, the system may be
heard working or a reduction in
acceleration may be noticed. This is
normal and does not mean there is
a problem with the vehicle.
Examples of these conditions
include hard acceleration in a turn,
an abrupt upshift or downshift of the
transmission or driving on rough
roads.
If cruise control is being used
when TCS begins to limit wheel
spin, the cruise control automatically
disengages. The cruise control
can be re-engaged when road
conditions allow. See
Cruise Control
on page 9‑47.
The message TRACTION FAULT
appears in the Driver Information
Center (DIC) when a TCS or
Antilock Brake System (ABS)
problem has been detected and the vehicle needs service. When
this message is on, the system will
not limit wheel spin. Adjust your
driving accordingly. See
Ride
Control System Messages on
page 5‑26.
The TCS/StabiliTrak light will flash
on the instrument panel cluster
when the TCS system or StabiliTrak
is both on and activated.
The TCS/StabiliTrak button is
located on the instrument panel.

Cruise Control
With cruise control, a speed of
about 40 km/h (25 mph) or more can
be maintained without keeping your
foot on the accelerator. Cruise
control does not work at speeds
below about 40 km/h (25 mph).
If the brakes are applied, the cruise
control shuts off.
{WARNING
Cruise control can be dangerous
where you cannot drive safely at
a steady speed. So, do not use
the cruise control on winding
roads or in heavy traffic.
Cruise control can be dangerous
on slippery roads. On such roads,
fast changes in tire traction can
cause excessive wheel slip, and
you could lose control. Do not use
cruise control on slippery roads.If the vehicle's StabiliTrak
®/Traction
Control System (TCS) begins to
limit wheel spin while the cruise
control is on, the cruise control
automatically disengages. See
StabiliTrak
®System on page 9‑45 or
Traction Control System (TCS) on
page 9‑44. When road conditions
allow you to safely use it again, the
cruise control can be turned
back on.
These controls are located at the
end of the multifunction lever.
9(Off): Turns the system off.
R(On):Turns the system on.
+ (Resume/Accelerate): Use to
make the vehicle accelerate or
resume a previously set speed.
r T(Set): Press the button at
the end of the lever to set the
speed.
Setting Cruise Control
If the cruise button is on when not in
use, it could get bumped and go into
cruise when not desired. Keep the
cruise control switch off when cruise
is not being used.
1. Move the cruise control lever to
R.
2. Get up to the speed desired.
3. Press
r Tat the end of the
lever and release it.

This would allow fuel to evaporate
into the atmosphere. If the fuel cap
is not properly installed, the FUEL
CAP message appears on the
Driver Information Center (DIC) and
the check engine light will be lit on
the instrument panel cluster. See
Fuel System Messages on
page 5‑25andMalfunction Indicator
Lamp on page 5‑12 for more
information.

refueling, do not remove the
nozzle. Shut off the flow of fuel
by shutting off the pump or by
notifying the station attendant.
Leave the area immediately.
Notice: If a new fuel cap is
needed, be sure to get the right
type of cap from your dealer. The
wrong type of fuel cap might not
fit properly, might cause the
malfunction indicator lamp to light, and could damage the fuel
tank and emissions system. See
Malfunction Indicator Lamp on
page 5‑12.
Filling a Portable Fuel
Container
{WARNING
Never fill a portable fuel container
while it is in the vehicle. Static
electricity discharge from the
container can ignite the fuel
vapor. You can be badly burned
and the vehicle damaged if this
occurs. To help avoid injury to you
and others:
.Dispense fuel only into
approved containers.
.Do not fill a container while it
is inside a vehicle, in a
vehicle's trunk, pickup bed,
or on any surface other than
the ground.
(Continued)
WARNING (Continued)
.Bring the fill nozzle in contact
with the inside of the fill
opening before operating the
nozzle. Contact should be
maintained until the filling
is complete.
.Do not smoke while

Vehicle Care 10-27
Brakes
This vehicle has front disc brakes
and rear drum 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 can come and go or be
heard all the time the vehicle is
moving, except when applying the
brake pedal firmly.
{WARNING
The brake wear warning sound
means that soon the brakes will
not work well. That could lead to
a crash. When the brake wear
warning sound is heard, have the
vehicle serviced.
Notice: Continuing to drive with
worn-out brake pads could result
in costly brake repair. Some driving conditions or climates
can cause a brake squeal when the
brakes are first applied or lightly
applied. This does not mean
something is wrong with the brakes.
Properly torqued wheel nuts are
necessary to help prevent brake
pulsation. When tires are rotated,
inspect brake pads for wear and
evenly tighten wheel nuts in the
proper sequence to torque
specifications in
Capacities and
Specifications on page 12‑2.
Rear drum brakes do not have
wear indicators, but if a rear brake
rubbing noise is heard, have the
rear brake linings inspected
immediately. Rear brake drums
should be removed and inspected
each time the tires are removed for
rotation or changing. Drum brakes
have an inspection hole to inspect
lining wear during scheduled
maintenance. When the front brake
pads are replaced, have the rear
brakes inspected, too. Brake linings should always be
replaced as complete axle sets.
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
that brake service might be
required.
Brake Adjustment
Every time the brakes are applied,
with or without the vehicle moving,
the 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. The vehicle was designed
and tested with top-quality brake
parts. When parts of the braking
system are replaced, be sure to get
new, approved replacement parts.

Tire Pressure Monitor
Operation
This vehicle may have a Tire
Pressure Monitor System (TPMS).
The TPMS is designed to warn the
driver when a low tire pressure
condition exists. TPMS sensors are
mounted onto each tire and wheel
assembly on your vehicle, excluding
the spare tire. The TPMS sensors
monitor the air pressure in your tires
and transmit the tire pressure
readings to a receiver located in
the vehicle.
When a low tire pressure condition
is detected, the TPMS illuminates
the low tire pressure warning light
located on the instrument cluster.If the warning light comes on, stop
as soon as possible and inflate the
tires to the recommended pressure
shown on the tire loading
information label. See
Vehicle Load
Limits on page 9‑18.
A message to check the pressure in
a specific tire displays in the Driver
Information Center (DIC). The low
tire pressure warning light and the
DIC warning message come on at
each ignition cycle until the tires are
inflated to the correct inflation
pressure. For additional information
and details about the DIC operation
and displays see Driver Information
Center (DIC) on page 5‑20 andTire
Messages on page 5‑27.
The low tire pressure warning light
may come on in cool weather when
the vehicle is first started, and then
turn off as the vehicle is driven. This
could be an early indicator that the
air pressure is getting low and
needs to be inflated to the proper
pressure. A Tire and Loading Information label
shows the size of the original
equipment tires and the correct
inflation pressure for the tires when
they are cold. See
Vehicle Load
Limits on page 9‑18, for an example
of the Tire and Loading Information
label and its location on your
vehicle. Also see Tire Pressure on
page 10‑54.
Your vehicle's TPMS can warn you
about a low tire pressure condition
but it does not replace normal tire
maintenance. See Tire Inspection
on page 10‑61, Tire Rotation on
page 10‑61 andTires on
page 10‑48.
Notice: Tire sealant materials are
not all the same. A non-approved
tire sealant could damage the
TPMS sensors. TPMS sensor
damage caused by using an
incorrect tire sealant is not
covered by the vehicle
warranty. Always use only the
GM-approved tire sealant
available through your dealer or
included in the vehicle.

Vehicle Care 10-59
TPMS Malfunction Light and
Message
The TPMS will not function properly
if one or more of the TPMS sensors
are missing or inoperable. When the
system detects a malfunction, the
low tire pressure warning light
flashes for about one minute and
then stays on for the remainder of
the ignition cycle. A DIC warning
message also displays. The
malfunction light and DIC warning
message come on at each ignition
cycle until the problem is corrected.
Some of the conditions that can
cause these to come on are:
.One of the road tires has been
replaced with the spare tire.
The spare tire does not have a
TPMS sensor. The malfunction
light and the DIC message
should go off after the road tire
is replaced and the sensor
matching process is performed
successfully. See "TPMS Sensor
Matching Process" later in this
section.
.The TPMS sensor matching
process was not done or not
completed successfully after
rotating the vehicle's tires. The
malfunction light and the DIC
message should go off once the
TPMS sensor matching process
is performed successfully.
See“TPMS Sensor Matching
Process” later in this section.
.One or more TPMS sensors are
missing or damaged. The
malfunction light and the DIC
message should go off when the
TPMS sensors are installed and
the sensor matching process is
performed successfully. See
your dealer for service.
.Replacement tires or wheels do
not match the original equipment
tires or wheels. Tires and wheels
other than those recommended
could prevent the TPMS from
functioning properly. See Buying
New Tires on page 10‑63.
.Operating electronic devices or
being near facilities using radio
wave frequencies similar to the
TPMS could cause the TPMS
sensors to malfunction.
If the TPMS is not functioning
properly, it cannot detect or signal a
low tire condition. See your dealer
for service if the TPMS malfunction
light and DIC message comes on
and stays on.
TPMS Sensor Matching
Process
Each TPMS sensor has a unique
identification code. The identification
code needs to be matched to a new
tire/wheel position after rotating the
vehicle’s tires or replacing one or
more of the TPMS sensors. Also,
the TPMS sensor matching process
should be performed after replacing
a spare tire with a road tire
containing the TPMS sensor.
