SERVICE STABILITY SYSTEM
- 54 : If you ever
see the SERVICE STABILITY SYSTEM message,
it means there may be a problem with your stability
enhancement system. If you see this message, try to
reset the system (stop; turn off the engine; then start the
engine again). If the SERVICE STABILITY SYSTEM
message still comes on, it means there is a problem.
You should see your dealer for service. Reduce your
speed and drive accordingly.
STABILITY SYSTEM ACTIVE
- 55 : You may see
the STABILITY SYSTEM ACTIVE message on the
Driver Information Center. It means that an advanced,
computer
-controlled system has come on to help your
vehicle continue to go in the direction in which you're
steering. This stability enhancement system activates
when the computer senses that your vehicle is just
starting to spin, as it might if you hit a patch of ice or
other slippery spot on the road. When the system is on,
you may hear a noise or feel a vibration in the brake
pedal. This is normal.

Be sure to continue scanning your displays, controls and
driving environment just as you would in a vehicle
without HUD. If you never look at your instrument
panel cluster, you may not see something important,
such as a warning light.
NOTICE:
Although the HUD image appears to be near the
front of the vehicle, do not use it as a parking aid.
The HUD was not designed for that purpose. If
you try to use the display as a marker for the
front of your vehicle, such as in a parking lot, you
may misjudge distance and hit an obstacle or
another vehicle.
The HUD controls are located on the instrument panel to
the left of the steering wheel.
1. Start your engine and slide the HUD dimmer lever
all the way up.
The brightness of the HUD image is determined by
an internal photo
-cell, and where you have the HUD
dimmer control set.
2. Adjust the seat to your driving position. Press the
image height adjuster switch to raise the image as far
as possible.

Sun and temperature sensors automatically adjust the air
temperature, the airflow direction and the fan speed to
maintain your temperature setting. The system may
supply cooler air to the side of the vehicle toward the
sun. Be careful not to put anything over the sensor on
top of the dash.
The display will show fan speed, temperature level
setting and airflow direction for a few seconds whenever
AUTO is selected, and then it will display the outside
temperature. The outside temperature reading is most
accurate when the vehicle is moving. During stops, the
display shows the previous temperature for best
accuracy and system control.
To find your preferred temperature setting, start with the
system in AUTO mode and the TEMP button adjusted
to 75
F (24
C), give the vehicle about 20 minutes to
stabilize, and adjust your temperature setting if
necessary, by using the TEMP button. The display will
show the temperature setting for a few seconds and then
it will display the outside temperature. If you want to
see your current automatic fan speed, airflow direction
and temperature setting, press the AUTO button.In cold weather, the system will delay turning on the fan,
to avoid blowing cold air. During this delay the system
will be in FRONT defrost mode and the light in the button
will come on and stay on as long as the display is showing
the current mode, set TEMP and FAN speed. This light
will go off when the display returns to the outside
temperature. The length of the delay depends on the
engine coolant temperature and the outside temperature.
Pushing the FAN, AIR FLOW or FRONT buttons will
override this delay, turn off the AUTO setting and return
the system to manual operation.
Personal Choice Comfort Controls
(If Equipped)
This feature enables up to two drivers to store and recall
comfort control settings for the temperature, fan speed
and the direction of the airflow.
The memory buttons (1 or 2) for this feature are located
on the driver's door panel and correspond to the
numbers (1 or 2) found on the back of each keyless
entry transmitter.
To recall comfort settings, press the unlock button on the
remote keyless entry transmitter and put the ignition in
ACCESSORY or RUN. The climate control setting last
chosen by the identified driver (1 or 2) will be recalled.

Ventilation Tips

Keep the hood and front air inlet free of ice, snow or
any other obstruction such as leaves. The heater and
defroster will work better, reducing the chance of
fogging your windows.

Keep the air path under the front seats clear
of objects. This helps air to circulate throughout
your vehicle.

When the engine idles for a long time, the exterior
temperature sensor may cause the system to blow air
that is too cool. Once the vehicle is moving again,
the system will try to maintain the set temperature
inside your vehicle.

When you start your vehicle and the EXT display
flashes (Dual Automatic ComforTemp system only)
for some time, the system may need repair. See
your dealer.Steering Wheel Controls for Climate
Control (If Equipped)
If your vehicle has this feature, you can control the
temperature function by using the buttons located on
your steering wheel.
Press the TEMP
(Temperature) up arrow
to increase the temperature
and the TEMP
(Temperature) down
arrow to decrease
the temperature.

Audio Systems
Your audio system has been designed to operate easily
and give years of listening pleasure. You will get the
most enjoyment out of it if you acquaint yourself with it
first. Find out what your audio system can do and how
to operate all of its controls to be sure you're getting the
most out of the advanced engineering that went into it.
Your vehicle has a feature called Retained Accessory
Power (RAP). With RAP, you can play your audio
system even after the ignition is turned off. See
ªRetained Accessory Power (RAP)º in the Index.
Setting the Clock
Press and hold H until the correct hour appears. AM will
appear on the display for morning hours. Press and hold
M until the correct minute appears. The clock may be
set with the ignition on or off.
To set the clock to the time of an FM station
broadcasting Radio Data System (RDS) information,
press and hold H and M at the same time until TIME
UPDATED appears on the display. If the time is not
available from the station, NO UPDATE will appear on
the display.
AM-FM Stereo with Cassette Tape Player

NOTICE:
Before you add any sound equipment to your
vehicle
-- like a tape player, CB radio, mobile
telephone or two
-way radio -- be sure you can
add what you want. If you can, it's very
important to do it properly. Added sound
equipment may interfere with the operation of
your vehicle's engine, Delphi Electronics radio or
other systems, and even damage them. Your
vehicle's systems may interfere with the
operation of sound equipment that has been
added improperly.
So, before adding sound equipment, check with
your dealer and be sure to check federal rules
covering mobile radio and telephone units.
Care of Your Cassette Tape Player
A tape player that is not cleaned regularly can cause
reduced sound quality, ruined cassettes or a damaged
mechanism. Cassette tapes should be stored in their
cases away from contaminants, direct sunlight and
extreme heat. If they aren't, they may not operate
properly or may cause failure of the tape player.
Your tape player should be cleaned regularly after
every 50 hours of use. Your radio may display CLEAN
PLAYER to indicate that you have used your tape player
for 50 hours without resetting the tape clean timer. If
this message appears on the display, your cassette tape
player needs to be cleaned. It will still play tapes, but
you should clean it as soon as possible to prevent
damage to your tapes and player. If you notice a
reduction in sound quality, try a known good cassette
to see if it is the tape or the tape player at fault. If this
other cassette has no improvement in sound quality,
clean the tape player.
The recommended cleaning method for your cassette
tape player is the use of a scrubbing action,
non
-abrasive cleaning cassette with pads which scrub
the tape head as the hubs of the cleaner cassette turn.
The recommended cleaning cassette is available through
your dealer (GM Part No. 12344789).

4-7
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're driving, brake
normally but don't 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 (ABS)
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, or when you 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, and you may even notice that your
brake pedal moves or pulses a little. This is normal.
If there's a problem with
the anti
-lock brake system,
this warning light will stay
on. See ªAnti
-Lock Brake
System Warning Lightº in
the Index.
