SERVICE STABILITRAK
This message displays if there has been a
problem detected with the StabiliTrak®system.
If this message comes on while you are driving,
pull off the road as soon as possible and stop
carefully. Try resetting the system by turning the
ignition off then back on. If this message still stays
on or comes back on again while you are
driving, your vehicle needs service. Have the
StabiliTrak
®system inspected by your dealer as
soon as possible. SeeStabiliTrak®System
on page 283for more information.
SERVICE SUSPENSION SYS (System)
This message displays when the magnetic
ride control or automatic leveling control system is
not operating properly. Have your vehicle
serviced by your dealer.
SERVICE THEFT DETERRENT SYSTEM
This message displays when there is a problem
with the theft-deterrent system programmed in the
key. A fault has been detected in the system
which means that the system is disabled and it is
not protecting the vehicle. The vehicle usually
restarts; however, you may want to take the
vehicle to your dealer before turning off the engine.
SeePASS-Key
®III+ Operation on page 114for
more information.
SERVICE TIRE MONITOR SYSTEM
If your vehicle has a Tire Pressure Monitor (TPM)
system, this message displays if a part on the
system is not working properly. If you drive your
vehicle while any of the four sensors are
missing or inoperable, the warning comes on in
about 10 minutes. A sensor would be missing, for
example, if you put different wheels on your
vehicle without transferring the sensors. If the
warning comes on and stays on, there may be a
problem with the TPM. See your dealer.

If there is a problem detected with StabiliTrak®,a
SERVICE STABILITRAK message will be
displayed on the Driver Information Center. See
DIC Warnings and Messages on page 220. When
this message is displayed, the system is not
operational. Driving should be adjusted
accordingly.
StabiliTrak
®comes on automatically whenever you
start your vehicle. To help assist you with
directional control of the vehicle, you should
always leave the system on. You can turn
StabiliTrak
®off if you ever need to through the TC
(traction control) on/off button. A STABILITRAK
OFF message will appear in the DIC when it has
been turned off. SeeTraction Control System
(TCS) on page 281.
If your vehicle is in cruise control when the
StabiliTrak
®activates, the cruise control will
automatically disengage. When road conditions
allow you to safely use it again, you may reengage
the cruise control. SeeCruise Control on
page 174for more information.
Panic Brake Assist
Your vehicle has a panic brake assist system that
monitors the intention of the driver while braking.
If the system senses that the driver has applied
hard/fast pressure to the brake pedal, the system
will generate additional pressure, making it
easier for the driver to maintain brake application.
When this happens the brake pedal will feel
easier to push. Just hold the brake pedal down
rmly and let the system work for you. You
may feel the brakes vibrate, or you may notice
some noise but this is normal. The brakes
will return to normal operation after the brake
pedal has been released.
All-Wheel Drive (AWD) System
If your vehicle is equipped with this feature, engine
power is sent to all four wheels all the time. This
is like four-wheel drive, but it is fully automatic.

With the proper preparation and equipment, many
vehicles can be towed in these ways. See
“Dinghy Towing” and “Dolly Towing,” following.
Here are some important things to consider before
you do recreational vehicle towing:
What’s the towing capacity of the towing
vehicle? Be sure you read the tow vehicle
manufacturer’s recommendations.
How far will you tow? Some vehicles have
restrictions on how far and how long they
can tow.
Do you have the proper towing equipment?
See your dealer or trailering professional
for additional advice and equipment
recommendations.
Is your vehicle ready to be towed? Just as
you would prepare your vehicle for a long
trip, you’ll want to make sure your vehicle is
prepared to be towed. SeeBefore Leaving on
a Long Trip on page 313.
Dinghy Towing
Notice:If you tow your vehicle with all
four wheels on the ground, the drivetrain
components could be damaged. The repairs
would not be covered by your warranty. Do not
tow your vehicle with all four wheels on the
ground.
Your vehicle was not designed to be towed with
all four wheels on the ground. If your vehicle must
be towed, see “Dolly Towing” following for more
information.
Dolly Towing
Notice:Towing an all-wheel-drive vehicle with
all four wheels on the ground, or even with
only two of its wheels on the ground, will
damage drivetrain components. Do not tow an
all-wheel-drive vehicle if any of its wheels
will be on the ground.
329

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 rmly.
{CAUTION:
The brake wear warning sound means that
soon the brakes will not 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 rst 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 tighten
wheel nuts in the proper sequence to GM torque
speci cations.
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 of brake trouble.
Brake Adjustment
Every time you make a brake stop, your disc
brakes adjust for wear.
