Keeping your mind on the drive is important for safe
driving. For more information, seeDefensive Driving
on page 5-2.
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.
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.Your vehicle has a feature called Retained Accessory
Power (RAP). With RAP, the audio system can be
played even after the ignition is turned off. SeeRetained
Accessory Power (RAP) on page 2-22for more
information.
Theft-Deterrent Feature
THEFTLOCK®is designed to discourage theft of
your vehicle’s radio. The feature works automatically
by learning a portion of the Vehicle Identication
Number (VIN). If the radio is moved to a different
vehicle, it will not operate. If the radio is removed
from your vehicle, the original VIN in the radio can
be used to trace the radio back to your vehicle.
With THEFTLOCK
®activated, the radio will not
operate if stolen.

Navigation Audio System
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. 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.
Your vehicle has a feature called Retained Accessory
Power (RAP). With RAP, the audio system can be
played even after the ignition is turned off. SeeRetained

Avoid needless heavy braking. Some people drive
in spurts — heavy acceleration followed by heavy
braking — rather than keeping pace with traffic.
This is a mistake. Your brakes may not have time to
cool between hard stops. Your brakes will wear out
much faster if you do a lot of heavy braking. If you
keep pace with the traffic and allow realistic following
distances, you will eliminate a lot of unnecessary braking.
That means better braking and longer brake life.
If your engine ever stops while you are driving, brake
normally but do not pump your brakes. If you do,
the pedal may get harder to push down. If your engine
stops, you will still have some power brake assist.
But you will use it when you brake. Once the power
assist is used up, it may take longer to stop and
the brake pedal will be harder to push.
Adding non-GM accessories can affect your vehicle’s
performance. SeeAccessories and Modications
on page 6-3.Anti-Lock Brake System (ABS)
Your vehicle has the Anti-Lock Brake System (ABS),
an advanced electronic braking system that will
help prevent a braking skid.
When you start your engine and begin to drive away,
ABS will check itself. You may hear a momentary motor
or clicking noise while this test is going on, and you
may even notice that your brake pedal moves a
little. This is normal.
If there is a problem with
ABS, this warning light will
stay on. SeeAnti-Lock
Brake System Warning
Light on page 3-55.
