Auto Memory Recall (Automatic
Transmission only):If your automatic
transmission vehicle has the memory package,
you may have this option. This option allows
the driver’s seat, the telescopic steering column,
if your vehicle has this feature, and the outside

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/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 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 91for more information.
Setting the Time
With the ignition on and the radio off, press
the H or the M button to enter clock mode.
Press and hold H until the correct hour appears
on the display. Press and hold M until the
correct minute appears on the display.
To change the time default setting from 12 hour
to 24 hour, press either the H or the M button
to enter the clock mode. Press the tune knob
to select between the 12 or 24 hour display format.
The clock mode automatically times out with
the changed display format set as the current

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 could 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 can take longer to stop and the brake pedal
will be harder to push.
Under certain weather or operating conditions,
occasional brake squeak, squeal, or other
noise might be heard with your vehicle’s
performance braking system. This brake system
is designed for superior fade resistance and
consistent operation using high performance
brake pads. Brake noise is normal and does
not affect system performance.
Adding non-dealer/non-retailer accessories
can affect your vehicle’s performance. See
Accessories and Modications on page 319.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 might hear
a momentary motor or clicking noise while this
test is going on, and you might 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 197.
279

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 might hear a motor or clicking noise and
feel the brake pedal move a little during a stop,
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 called
TCS that limits wheel spin. This is especially useful
in slippery road conditions. The system operates
only if it senses that the rear wheels are spinning
too much or are beginning to lose traction.
When this happens, the system works the rear
brakes and reduces engine power (by closing the
throttle and managing engine spark) to limit
wheel spin.
The TRACTION SYSTEM ACTIVE message
displays on the Driver Information Center (DIC)
when the TCS system is limiting wheel spin.
SeeDIC Warnings and Messages on page 214.
You may feel or hear the system working,
but this is normal.
If your vehicle is in cruise control when the
TCS 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. See
Turn Signal/Multifunction Lever on page 160.
