Audio System(s)
Determine which radio your vehicle has and then
read the pages following to familiarize yourself
with its features.
Driving without distraction is a necessity for a
safer driving experience. SeeDefensive Driving on
page 372. By taking a few moments to read this
manual and get familiar with your vehicle’s
audio system, you can use it with less effort, as
well as take advantage of its features. While your
vehicle is parked, set up your audio system by
presetting your favorite radio stations, setting the
tone, and adjusting the speakers. Then, when
driving conditions permit, you can tune to
your favorite stations using the presets and
steering wheel controls if the vehicle has them.{CAUTION:
This system provides you with a far greater
access to audio stations and song listings.
Giving extended attention to entertainment
tasks while driving can cause a crash and
you or others can be injured or killed.
Always keep your eyes on the road and
your mind on the drive — avoid engaging
in extended searching while driving.
Keeping your mind on the drive is important for
safe driving. Here are some ways in which you can
help avoid distraction while driving.
While your vehicle is parked:
Familiarize yourself with all of its controls.
Familiarize yourself with its operation.
Set up your audio system by presetting your
favorite radio stations, setting the tone, and

Navigation/Radio System
Your vehicle may have a navigation radio system.
The navigation system has built-in features
intended to minimize driver distraction. Technology
alone, no matter how advanced, can never
replace your own judgment. See the Navigation
System manual for some tips to help you
reduce distractions while driving.
Rear Seat Entertainment System
(Option A, Uplevel)
Your vehicle may have this type of DVD Rear
Seat Entertainment (RSE) system. If it has
this feature, it will include a DVD player, a video
display screen, auxiliary inputs, two sets of
wireless headphones (if included), and a remote
control.

Section 4 Driving Your Vehicle

Control of a Vehicle
You have three systems that make your vehicle
go where you want it to go. They are the brakes,
the steering, and the accelerator. All three
systems have to do their work at the places where
the tires meet the road.
Sometimes, as when you are driving on snow or
ice, it is easy to ask more of those control systems
than the tires and road can provide. That means
you can lose control of your vehicle. SeeTraction
Control System (TCS) on page 379and
StabiliTrak
®System on page 381.
Adding non-GM accessories can affect your
vehicle’s performance. SeeAccessories and
Modications on page 426.
Braking
SeeBrake System Warning Light on page 238.
Braking action involves perception time and
reaction time.
First, you have to decide to push on the brake
pedal. That is perception time. Then you have to
bring up your foot and do it. That is reaction time.
Average reaction time is about three-fourths of a
second. But that is only an average. It might
be less with one driver and as long as two or
three seconds or more with another. Age, physical
condition, alertness, coordination, and eyesight
all play a part. So do alcohol, drugs, and
frustration. But even in three-fourths of a second,
a vehicle moving at 60 mph (100 km/h) travels
66 feet (20 m). That could be a lot of distance in an
emergency, so keeping enough space between
your vehicle and others is important.
And, of course, actual stopping distances vary
greatly with the surface of the road, whether it is
pavement or gravel; the condition of the road,
whether it is wet, dry, or icy; tire tread; the
condition of the brakes; the weight of the vehicle;
and the amount of brake force applied.
376

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.
379

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 vehicleever gets stuck in sand, mud or snow and rocking
the vehicle is required. SeeRocking Your Vehicle to
Get It Out on page 404andIf Your Vehicle is Stuck
in Sand, Mud, Ice, or Snow on page 403.
To turn the system off,
press the traction
control button located
on the center of
the instrument panel.
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 426for 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.
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 249.
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.
381

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 404andIf Your Vehicle is Stuck in
Sand, Mud, Ice, or Snow on page 403.
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 limitedmode, 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.
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 200.
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.
