Key In the Ignition
Never leave your vehicle with the keys inside, as it
is an easy target for joy riders or thieves. If you
leave the key in the ignition and park your vehicle,
a chime will sound, when you open the driver’s
door. Always remember to remove your key from
the ignition and take it with you. This will lock
your ignition and transaxle. Also, always remember
to lock the doors.
The battery could be drained if you leave the
key in the ignition while your vehicle is parked.
You may not be able to start your vehicle after
it has been parked for an extended period of time.
Retained Accessory Power (RAP)
After you turn the ignition off and remove the key,
you will still have power to such accessories as the
power windows, clock, radio, and if equipped, audio
steering wheel controls and sunroof. The power
to the accessories can last up to 10 minutes. The
instrument panel cluster lights will stay on for a
few seconds, then will go out. Once you open the
driver’s door, the power will shut off. Your vehicle
has a feature designed to protect the battery
against drainage. For more information see
Inadvertent Power Battery Saver on page 177
andElectric Power Management on page 176.

the anti-lock brake system warning light may also
be displayed on the instrument panel cluster. See
Brake System Warning Light on page 201and
Anti-Lock Brake System Warning Light on page 202
for more information. If this happens, stop as soon

needs service. See your dealer as soon as
possible. SeeBrakes on page 367for more
information.
SERVICE BRAKE SYSTEM

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 115for more information.Setting the Time
(Without Date Display)
If your vehicle has an AM/FM base radio with a
single CD player and preset buttons numbered one
through six, the radio will have a clock button for
setting the time. You can set the time by following
these steps:
1. Press the clock button until the hour numbers
begin ashing on the display. Press the clock
button a second time and the minute numbers
will begin ashing on the display.
2. While either the hour or the minute numbers
are ashing, turn the tune knob, located on
the upper right side of the radio, clockwise
or counterclockwise to increase or decrease
the time. Instead of using the tune knob,
you can also press the SEEK, FWD (forward),
or REV (reverse) buttons to adjust the time.
3. Press the clock button again until the clock
display stops ashing to set the currently
displayed time; otherwise, the ashing will
stop after ve seconds and the current time
displayed will be automatically set.

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.
Theft-Deterrent Feature
THEFTLOCK®is designed to discourage theft of
your vehicle’s radio. It works by using a secret code
to disable all radio functions whenever battery
power is removed and the radio is placed in a
different vehicle. This feature requires no user input
to be activated. The radio is automatically armed
when it is put into the vehicle for the rst time.
If THEFTLOCK
®is activated, the radio will not
operate if stolen. The radio will display LOCKED.
If this occurs, the radio will need to be returned
to your GM dealer.
Audio Steering Wheel Controls
If your vehicle has audio
steering wheel controls,
they may be differ
depending on your
vehicle’s options. Some
audio controls can be
adjusted at the steering
wheel. They include the
following:
xw(Next/Previous):Press the up or the down
arrow to go to the next or to the previous radio
station stored as a favorite.
When a CD is playing, press the up or the down
arrow to go to the next or previous track.

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
hear the anti-lock pump or motor operate, and feel
the brake pedal pulsate, 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 has a traction control system that limits
wheel spin. This is especially useful in slippery road
conditions. The system operates only if it senses
that the front wheels are spinning too much or
beginning to lose traction. When this happens, the
system works the front brakes and reduces engine
power (by closing the throttle and managing engine
spark) to limit wheel spin.
The traction control system and StabiliTrak
®
warning light will ash when the traction control
system is limiting wheel spin. SeeTraction Control
System (TCS) Warning Light on page 202for
more information. 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.
SeeCruise Control on page 167for more
information.
