The tape is tight and the player cannot turn the
tape hubs. Remove the tape. Hold the tape with
the open end down and try to turn the right
hub counterclockwise with a pencil. Turn the tape
over and repeat. If the hubs do not turn easily,
the tape may be damaged and should not be used

Radio Personalization
If your vehicle has this feature, it allows the driver to
return to the last used source: radio, cassette, or
CD using the remote keyless entry transmitter. This
feature can also store and recall AM and FM presets,
volume, tone, and the last selected radio station.
The number on the back of each transmitter, 1 or 2,
corresponds to driver 1 or 2. If transmitter 1 is used to
enter the vehicle, the last used audio source and/or
settings set by driver 1 will be recalled. If transmitter 2
is used to enter the vehicle, the last used audio
source and/or settings set by driver 2 will be recalled.
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 and LOCKED will appear on the display.
When the radio and vehicle are turned off, the blinking
red light indicates that THEFTLOCK
®is armed.
With THEFTLOCK
®activated, the radio will not operate
if stolen.
Audio Steering Wheel Controls
Some audio controls can be adjusted at the steering
wheel. They include the following:
g(OnStar/Voice Recognition):If your vehicle has

Section 4 Driving Your Vehicle
4-1

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.Anti-lock Brake System
Your vehicle has anti-lock brakes. ABS is an advanced
electronic braking system that will help prevent a
braking skid.
When you start your engine and begin to drive away, your
anti-lock brake system will check itself. You may hear a
momentary motor or clicking noise while this test is going
on. This is normal.
If there is a problem with
the anti-lock brake system,
this warning light will
stay on. SeeAnti-Lock
Brake System Warning
Light on page 3-42.
Along with ABS, your vehicle has a Dynamic Rear
Proportioning (DRP) system. If there is a DRP problem,
both the brake and ABS warning lights will come on
accompanied by a 10-second chime. The lights and
chime will come on each time the ignition is turned on
until the problem is repaired. See your dealer for service.
4-7

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.The anti-lock system 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.
