Selecting Your Mobile Digital Media as the
Active Source
Your radio and rear seat entertainment system
communicate with the GM Mobile Digital Media
system, as one compact unit that can be accessed
by everyone seated inside the vehicle. The GM
Mobile Digital Media system can hold thousands of
songs, hours of videos, and hundreds of games.
To help use this system, see the following
“Quick Start” information:
Front seat driver and passenger, use the radio
and steering wheel controls to access the music
collection with PhatNoise Voice Index™
technology. The preset buttons can be used to
select the browsing category. The Next,
Previous, and Seek buttons can be used to
browse within a browsing category. Browse the
music collection by artist, album, genre, or
custom playlist as the system uses the voice
mode to announce these selections. See “Using
the GM Mobile Digital Media System for Front
Seat Audio Entertainment” later in this manual.
Rear seat passengers, use the wireless DVD
remote control to navigate the menu displayed
on the overhead DVD video screen, then selectto play music, videos, or games. A dedicated
game controller is included with the Mobile
Digital Media package. See “Using the GM
Mobile Digital Media System for Rear Seat
Entertainment” later in this manual.
Your vehicle may have audio steering wheel
controls. Some audio controls can be adjusted at
the steering wheel. SeeAudio Steering Wheel

Let us say the road is wet and you are driving
safely. Suddenly, an animal jumps out in front of
you. You slam on the brakes and continue braking.
Here is 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
wheel.ABS can change the brake pressure faster than
any driver could. The computer is programmed to
make the most of available tire and road
conditions. This can help you steer around the
obstacle while braking hard.
As you brake, your computer keeps receiving
updates on wheel speed and controls braking
pressure accordingly.
352

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 your 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 may feel a slight brake pedal pulsation
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.
Traction Control System (TCS)
Your vehicle may have a traction control system
that limits wheel spin. This is especially useful
in slippery road conditions. The system operates if
it senses that one or both of the front wheels
are spinning or beginning to lose traction. When
this happens, the system brakes the spinning
wheel(s) and/or reduces engine power to
limit wheel spin.
The TRACTION CONTROL ACTIVE message will
come on in the Driver Information Center (DIC)
when the traction control system is limiting wheel
spin. You may feel or hear the system working,
but this is normal.
If your vehicle is in cruise control when the
traction control system begins to limit wheel spin,
the cruise control will automatically disengage.
When road conditions allow you to safely
use it again, you may re-engage the cruise control.
353

This warning light will
come on to let you
know if there is
a problem with your
traction control system.
When this warning light is on, the system will not
limit wheel spin. Adjust your driving accordingly.
If the SERVICE TRACTION SYSTEM message in
the DIC comes on and stays on or comes on
while you are driving, there’s a problem with your
traction control system. Have the traction
control system serviced by your GM dealer as
soon as possible.
When this warning message is on, the TRACTION
CONTROL OFF message in the DIC will come
on to remind you that the system will not limit
wheel spin. Adjust your driving accordingly.The traction control system automatically comes
on whenever you start your vehicle. To limit wheel
spin, especially in slippery road conditions, you
should always leave the system on. But you
can turn the traction control system off if you ever
need to. You should turn the system off if your
vehicle ever gets stuck in sand, mud or snow and
rocking the vehicle is required. SeeRocking
Your Vehicle to Get It Out on page 378andIf Your
Vehicle is Stuck in Sand, Mud, Ice, or Snow on
page 377.
To turn the system off,
press the traction
control button located
on the center of
the instrument panel.
354

If the system is limiting wheel spin when you
press the button, the TRACTION CONTROL
ACTIVE message will go off, but the system will
not turn off until there is no longer a current
need to limit wheel spin. The TRACTION
CONTROL OFF message will come on to remind
you the system is off. You can turn the system
back on at any time by pressing the button again.
The traction control system warning message
should go off.
Adding non-GM accessories can affect your
vehicle’s performance. SeeAccessories and
Modications on page 400for more information.
StabiliTrak®System
Your vehicle may be equipped with StabiliTrak®
which combines anti-lock brake, traction and
stability control systems and helps the driver
maintain directional control of the vehicle in most
driving conditions.
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 the system fails to turn on or activate, the
SERVICE STABILITY SYSTEM message will be
displayed on the Driver Information Center (DIC). If
the vehicle has gone through heavy acceleration
or braking or multiple turns during the rst
two miles of driving after starting your vehicle, the
STABILITY CONTROL OFF message may
appear on the DIC. If this is the case, your vehicle
does not need servicing. You will need to turn
the vehicle off and then restart it to initialize
StabiliTrak
®. If either message appears on the
DIC, and your vehicle has not gone through hard
acceleration, braking or multiple turns in the
rst two miles of driving, your vehicle should be
taken in for service.
The STABILITY CONTROL ACTIVE message will
appear on the DIC only when the system is both
on and activated. It means that an advanced
computer-controlled system has come on to help
your vehicle continue to go in the direction in which
you are steering. StabiliTrak
®activates when the
computer senses that your vehicle is just starting to
spin, as it might if you hit a patch of ice or other
slippery spot on the road. When the system
activates, you may hear a noise or feel a vibration in
the brake pedal. This is normal.
355

When the STABILITY CONTROL ACTIVE
message is on, you should continue to steer in the
direction you want to go. The system is designed to
help you in bad weather or other difficult driving
situations by making the most of whatever road
conditions will permit. For more information on the
stability messages, seeDriver Information Center
(DIC) on page 223.
If the StabiliTrak
®system turns off, the traction
control system warning light will illuminate, and the
STABILITY CONTROL OFF message will
appear on the DIC to warn the driver that
StabiliTrak
®is no longer available to assist you
with directional control of the vehicle. Adjust your
driving accordingly.
To realize the full benets of the stability
enhancement system, you should normally leave
StabiliTrak
®on, but it may be necessary to
turn the system off if your vehicle is stuck in sand,
mud, ice or snow, and you want to “rock” your
vehicle to attempt to free it. SeeRocking
Your Vehicle to Get It Out on page 378andIf
Your Vehicle is Stuck in Sand, Mud, Ice, or Snow
on page 377.
Traction Control Operation
The traction control system is part of the
StabiliTrak®system. Traction control limits wheel
spin by reducing engine power to the wheels
(engine speed management) and by applying
brakes.
The traction control system is enabled
automatically when you start your vehicle. It will
activate and display the TRACTION CONTROL
ACTIVE message in the DIC if it senses that one
or both of the front wheels are spinning or
beginning to lose traction while driving.
If the brake traction-control system activates
constantly or if the brakes have heated up due to
high-speed braking, brake traction-control will
be disabled and the TRACTION CONTROL
ACTIVE message will be displayed. In the limited
mode, the traction control system will only use
engine traction-control and is limited in its ability to
provide optimal performance since the system
will not utilize brake traction-control to control slip
on the drive wheels. The system will return to
normal operation after the brakes have cooled.
This can take up to two minutes or longer
depending on brake usage.
356

The traction control system may activate on
dry or rough roads or under conditions such as
heavy acceleration while turning or abrupt
upshifts/downshifts of the transaxle. When
this happens you may notice a reduction in
acceleration, or may hear a noise or vibration.
This is normal.
If your vehicle is in cruise control when the system
activates, the STABILITY CONTROL ACTIVE
message will appear on the DIC and the cruise
control will automatically disengage. When
road conditions allow you to use cruise again, you
may re-engage the cruise control. SeeCruise
Control on page 177.
StabiliTrak
®may also turn off automatically if it
determines that a problem exists with the system.
If the problem does not clear itself after restarting
the vehicle, you should see your dealer for
service.
Steering
Power Steering
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.
Steering Tips
It is important to take curves at a reasonable
speed.
A lot of the “driver lost control” accidents
mentioned on the news happen on curves.
Here is why:
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 is no traction, inertia will keep the vehicle
going in the same direction. If you have ever
tried to steer a vehicle on wet ice, you will
understand this.
357

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 are in a curve, speed is the one
factor you can control.
Suppose you are steering through a sharp curve.
Then you suddenly apply the brakes. Both
control systems — steering and braking — have
to do their work where the tires meet the road.
Unless you have four-wheel anti-lock brakes,
adding the hard braking can demand too much of
those places. You can lose control.
The same thing can happen if you are steering
through a sharp curve and you suddenly
accelerate. Those two control systems — steering
and acceleration — can overwhelm those
places where the tires meet the road and make
you lose control. SeeTraction Control System
(TCS) on page 353andStabiliTrak
®System on
page 355.What should you do if this ever happens? Ease up
on the brake or accelerator pedal, steer the
vehicle the way you want it to go, and slow down.
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 will
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.
Adding non-GM accessories can affect your
vehicle’s performance. SeeAccessories and
Modications on page 400.
