vehicle’s top speed is based on the top speed
rating of the tires. This ensures that your vehicle
stays in a safe operating range for the tires.

DIC Vehicle Personalization
If your vehicle has the Navigation system, see the
Navigation system manual for instructions on
operating the DIC for your vehicle.
Your vehicle has personalization that allows you to
program certain features to a preferred setting
for up to two people. The number of programmable
features varies depending upon which model of
the vehicle is purchased.
242

On all vehicles, features such as climate control
settings, radio preset settings, exterior lighting
at unlock, remote lock and unlock conrmation,
and automatic door locks have already been
programmed for your convenience.
Some vehicles have additional features that can
be programmed including the seat and outside
rearview mirror position.
If your vehicle has the ability to program additional
personalization features, the driver’s preferences
are recalled by pressing the unlock button on
the Remote Keyless Entry (RKE) transmitter,
1 or 2, or by pressing the appropriate memory
button, 1 or 2, located on the driver’s door. Certain
features can be programmed not to recall until
the key is placed in the ignition. To change feature
preferences, see “Entering the Personalization
Menu” following.Entering the Personalization Menu
To enter the feature programming mode, use the
following procedure:
1. Turn the ignition to ON, but do not start the
engine. Make sure an automatic transmission
is in PARK (P) or a manual transmission
has the parking brake set.
To avoid excessive drain on the battery, it is
recommended that the headlamps are
turned off.
2. If your vehicle has memory settings, press the
appropriate memory button, 1 or 2, located on
the driver’s door armrest. The DIC display
will show either Driver 1 or 2 depending
on which button was selected.
3. Press the PWR/VOL knob to turn the radio on.
4. Press the TUNE/SEL knob once to access the
main menu of the DIC.
5. Turn the TUNE/SEL knob until SETUP is
highlighted.
243

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 can interfere with the
operation of your vehicle’s engine, radio, or
other systems, and even damage them. Your
vehicle’s systems can 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 119for more information.Setting the Time
1. Press the TUNE/SEL (select) knob to enter
the main menu.
2. Turn the TUNE/SEL knob until SET CLOCK
appears on the display.
3. Press the TUNE/SEL knob to select
SET CLOCK.
4. Turn the TUNE/SEL knob to adjust the time.
5. Press the TUNE/SEL knob to update the
time. VEHICLE TIME UPDATED will appear
on the display.
If the CLOCK/RADIO DISP (display) is congured
into one of the congurable keys, pressing the key
will switch the display between the radio station
frequency and the time. See “Congurable Radio
Display Keys” underRadio with CD on page 260for
more information on conguring the keys.

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 332.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 the 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 the
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 206.
291

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 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)
(CTS)
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 one or both of the rear wheels are spinning or
beginning to lose traction. When this happens,
the system brakes the spinning wheel(s) and/or
reduces engine power to limit wheel spin.
You may feel or hear the system working, but this
is normal.
This warning light will
come on to let you
know if there is
a problem with your
traction control system.
SeeTraction Control System (TCS) Warning Light
on page 206. When this warning light is on, the
system will not limit wheel spin. Adjust your driving
accordingly.
