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.

The HUD controls
are located in the
overhead console.
1. Start your engine and slide the HUD dimmer control
all the way up.
The brightness of the HUD image is determined by
whether the headlamps are on or off, and where you
have the HUD dimmer control set.
2. Adjust the seat to your driving position. Slide the
image height adjuster control all the way up, raising
the image as far as possible.
3. Now slide the image height adjuster control down so
the image is as low as possible but still in full view.
4. Slide the dimmer control downward until the HUD
image is no brighter than necessary.To turn the HUD display off, slide the dimmer control
all the way down.
If the sun comes out, the sky becomes cloudy, or if you
turn your headlamps on, you may need to adjust the
HUD brightness using the dimmer control. Polarized
sunglasses could make the HUD image harder to see.
To change the display from English to metric units,
push the ENG/MET button located to the left of the
steering column.
Care of the HUD
Clean the inside of the windshield as necessary to
remove any dirt or film that reduces the sharpness or
clarity of the HUD image.
To clean the HUD lens, spray household glass cleaner
on a soft, clean cloth. Gently wipe and dry the HUD
lens. Do not spray cleaner directly on the lens to avoid
cleaner leaking inside the unit.

During stops, when driving slow, or when the engine is
first started after a short trip, the outside temperature
reading can be affected by road or engine heat. Also,
starting the engine within a short time after the vehicle
has been running will affect the reading. To ensure
proper automatic climate control operation, the outside
temperature display may not update as quickly
as expected.
Sun and temperature sensors automatically adjust the air
temperature, the airflow direction and the fan speed to
maintain your comfort setting. The system may supply
cooler air to the side toward the sun. Be careful not to
put anything over the sensors on top of the dash.
Temperature Button
To adjust the comfort level you want maintained inside
the vehicle, push the TEMP button. If you want a
warmer comfort level, push the red arrow. If you want a
cooler comfort level, push the blue arrow. Your comfort
setting is shown in the display.Fan Button
The speed of the blower fan is controlled automatically
if you have the system set for AUTO. Pressing the
FAN button will display and hold the current blower
fan setting.
If you want the blower fan to run at a lower speed, push
the bottom of the FAN button. The fan speed will
decrease with every push of the button until the lowest
speed is reached. If you want to increase the fan speed,
push the top of the FAN button. Notice the fan
indicators on the display.
Mode Controls
Press the AIR FLOW button to deliver air through the
floor, middle or windshield outlets. The system will stay
in the selected mode until the AUTO button is pushed.
Press the up or down arrow on the AIR FLOW button
to cycle through the available modes.

Automatic Operation
Press the AUTO button when you want the system to
automatically adjust to changes in the temperature.
When the system is set for automatic operation, air will
come from the floor, middle or windshield outlets
depending on the temperature inside the vehicle, the
outside temperature and sun load. Fan speed will vary as
the system gets to and maintains the comfort setting you
have selected through the use of the TEMP button.
To find your comfort setting, start with the system in
AUTO mode and the TEMP button adjusted to a display
of 75
F (24
C), give the vehicle about 20 minutes to
stabilize, and adjust your comfort setting if necessary, by
using the TEMP button. The display will show the
comfort setting, fan speed and airflow direction for a
few seconds, and then it will display the outside
temperature. If you choose the temperature setting of
60
F (15
C), the system will remain at the maximum
cooling setting and fan speed. If you choose the
temperature setting of 90
F (33
C), the system will
remain at the maximum heat setting and fan speed.
Choosing either maximum setting will not cause the
system to heat or cool any faster.In cold weather, the system will delay turning the fan on
high, to avoid blowing cold air. 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 change the fan speed.
Manual Operation
You may also manually adjust the air delivery or
fan speed.
AIR FLOW: This button is used to change the direction
of the airflow. The airflow choices available are FLOOR,
FLOOR
-MID, MID and WINDSHIELD-FLOOR.
If the system is set for AUTO, pressing the AIR FLOW
button will display the current airflow direction, the
comfort setting and the fan speed. Press the AIR
FLOW up or down button again to change the
direction of the airflow.
If the AIR FLOW up button is selected while in the
FRONT defrost mode, the system will direct the air
toward the mid
-position. If the AIR FLOW down button
is selected while in the FRONT defrost mode, the
system will direct the air toward the FLOOR, and the
FRONT defrost mode will cancel. Notice the arrows in
the display.

3-6 Air Conditioning
On hot days, open the windows long enough to let hot
inside air escape. This reduces the time it takes for your
vehicle to cool down. Then keep your windows closed
for the air conditioner to work its best.
On very hot days, the system will automatically enter
the RECIRC mode and the temperature door will be
positioned at the full cold position for maximum
cooling. If the system is not in the AUTO mode,
RECIRC should be selected to provide maximum
cooling. You can choose the extreme comfort setting
of 60
F (15
C), but the system will not cool any faster
by choosing the extreme comfort setting.
Heating
Press AUTO and adjust the temperature by pressing the
TEMP up or down arrow. You may also adjust the
ComforTemp system manually by pressing the AIR
FLOW button until FLOOR appears. Again, adjust the
temperature by pressing the TEMP up or down arrow.
Outside air is sent through the floor outlets. The heater
works best if you keep your windows closed.
Defogging and Defrosting
On cool but humid days, use FRONT to keep the
windshield and side windows clear and to quickly
remove fog, frost or ice from the windshield.
The fan speed will vary while in the AUTO mode. If a
manual fan speed setting is selected, the fan speed will
remain at that selection until the engine is turned off or
another selection has been made. To turn off FRONT,
press AUTO or AIR FLOW.
Rear Window Defogger
The lines you see on the
rear window warm the
glass. Press this button to
start warming your window.

3-9 Steering Wheel Controls for
Climate Control
You can control the
temperature function by
using the button on your
steering wheel. Press the
TEMP up arrow to increase
the temperature and the
TEMP 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 its controls, to be sure you're getting the
most out of the advanced engineering that went into it.
Setting the Clock
Press and hold HRS until the correct hour appears. Press
and hold MIN until the correct minute appears.
You may set the clock with the ignition off if you
press RECALL first and follow the same procedure
described above.

3-26
Cellular Phone Usage
Cellular phone usage may cause interference with your
vehicle's radio. This interference may occur when
making or receiving phone calls, charging the phone's
battery or simply having the phone ªon.º This
interference is described as an increased level of static
while listening to the radio. If you notice static while
listening to the radio, unplug the cellular phone and
turn it off.
Tips About Your Audio System
Hearing damage from loud noise is almost undetectable
until it is too late. Your hearing can adapt to higher
volumes of sound. Sound that seems normal can be loud
and harmful to your hearing. Take precautions by
adjusting the volume control on your radio to a safe
sound level before your hearing adapts to it.
To help avoid hearing loss or damage:

Adjust the volume control to the lowest setting.

Increase volume slowly until you hear comfortably
and clearly.
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 Delco 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.

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 Brakes (ABS)
Your vehicle has anti-lock brakes (ABS). 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.
