DIC Vehicle Customization
Your vehicle has customization capabilities that
allow you to program certain features to one
preferred setting. Customization features can only
be programmed to one setting on the vehicle and
cannot be programmed to a preferred setting for
two different drivers.
All of the customization options may not be
available on your vehicle. Only the options
available will be displayed on your DIC.
The default settings for the customization features
were set when your vehicle left the factory, but
may have been changed from their default
state since then.
The customization preferences are automatically
recalled.
To change customization preferences, use the
following procedure.

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.

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. The brakes may not have
time to cool between hard stops. The 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 vehicle’s engine ever stops while you are
driving, brake normally but do not pump the
brakes. If you do, the pedal may get harder to
push down. If the 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 325.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 202.
281

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.
283

The SERVICE TRACTION CONTROL message,
the traction control system warning light and
the StabiliTrak
®warning light will come on to let
you know if there is a problem with the traction
control system. SeeDIC Warnings and Messages
on page 221.
When this light and the SERVICE TRACTION
CONTROL message are on, 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 can turn the system on or off at any time by
pressing the traction control system button located
on the console. The DIC will display TRACTION
CONTROL OFF when you press the button.
Adding non-GM accessories can affect your
vehicle’s performance. SeeAccessories and
Modications on page 325for more information.
StabiliTrak®System
Your vehicle may have this feature. The
StabiliTrak®system is an advanced computer
controlled system that helps the driver maintain
directional control of the vehicle in difficult driving
conditions. This is accomplished by selectively
applying any one of the vehicle’s brakes and
reducing engine power. The StabiliTrak
®system
comes on automatically whenever you start
your vehicle. The system cannot be turned off.
The STABILITRAK NOT READY message may be
displayed in the DIC and the traction control system
and StabiliTrak
®warning light on the instrument
panel cluster will be on after rst driving the vehicle
and exceeding 19 mph (30 km/h) for 30 seconds.
The StabiliTrak
®system is off until the light has
turned off. This could take up to 15 minutes.
The traction control system and StabiliTrak
®
warning light on the instrument panel cluster will
ash when the system is operating. SeeTraction
Control System (TCS) Warning Light on page 202,
StabiliTrak
®Indicator Light on page 203andDIC
Warnings and Messages on page 221for more
information. You may also feel or hear the system
working. This is normal.
