Audio System(s)
Determine which radio your vehicle has and then read the
pages following to familiarize yourself with its features.
{CAUTION:
This system provides you with 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. SeeDefensive Driving on page 4-2.
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
adjusting the speakers. Then, when driving
conditions permit, you can tune to your favorite
radio stations using the presets and steering
wheel controls if the vehicle has them.
Notice:Before adding any sound equipment to
your vehicle, such as an audio system, CD player,
CB radio, mobile telephone, or two-way radio, make
sure that it can be added by checking with your
dealer/retailer. Also, check federal rules covering
mobile radio and telephone units. If sound equipment
can be added, it is very important to do it properly.
Added sound equipment may interfere with the
operation of your vehicle’s engine, radio, or other
systems, and even damage them. Your vehicle’s
systems may interfere with the operation of sound
equipment that has been added.
Notice:The chime signals related to safety belts,
parking brake, and other functions of your vehicle
operate through the radio/entertainment system.
If that equipment is replaced or additional equipment
is added to your vehicle, the chimes may not
work. Make sure that replacement or additional
equipment is compatible with your vehicle before
installing it. SeeAccessories and Modifications
on page 5-3.

When the radio and vehicle are turned off, the blinking
red light indicates that THEFTLOCK
®is armed.

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 front wheel
and at both rear wheels.
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, the computer keeps receiving updates on
wheel speed and controls braking pressure accordingly.
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 the 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 antilock work for you. You might
feel the brakes vibrate 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.
Locking Rear Axle
If your vehicle has this feature, your locking rear axle
can give you additional traction on snow, mud, ice,
sand or gravel. It works like a standard axle most of the
time, but when one of the rear wheels has no traction
and the other does, this feature will allow the wheel with
traction to move the vehicle.

StabiliTrak®System
Your vehicle is equipped with StabiliTrak®, Electronic
Stability Control (ESC) which combines antilock brake,
traction and stability control systems and helps the driver
maintain directional control of the vehicle in most driving
conditions.
Traction control activates when the controller senses
wheel spin. StabiliTrak
®will selectively apply the brakes
and reduce engine torque to help regain traction.
Stability control activates when the controller senses
a discrepancy between your intended path and the
direction the vehicle is travelling. StabiliTrak
®selectively
applies braking pressure at any one of the vehicle’s
brakes to help guide the vehicle in the direction which
you are steering.
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 driving conditions delay
system initialization, the STABILITRAK NOT READY
message may be displayed. If this is the case, your
vehicle does not need servicing.
For more information on the stability messages,
seeDIC Warnings and Messages on page 3-53.When the StabiliTrak
®
system is both on and
actively controlling the
stability of the vehicle,
the StabiliTrak
®light will
blink for the duration of
the event.
You may also feel or hear the system working.
This is normal.
The StabiliTrak
®disable
button is located on the
transmission shift handle.
The StabiliTrak
®system is automatically disabled in
4LO mode and cannot be turned on until the vehicle
is switched to 2HI, 4HI, or 4AWD.
The StabiliTrak
®system has three modes of operation:
STABILITRAK ON, TRACTION CONTROL OFF,
and STABILITRAK OFF.
STABILITRAK ON -The vehicle will default to
STABILITRAK ON every time the driver starts the
vehicle. The StabiliTrak
®light will be off and no DIC
messages will be displayed.
