3-6 Passenger Climate Control (If Equipped)
If your vehicle is equipped with the Dual Automatic
ComforTemp system, the front seat passenger can
control the air temperature in his or her seating area. The
control is located on the passenger's door armrest.The temperature can be set up to 5
F (3
C) cooler
or warmer than the primary setting. To activate the
passenger control, press the button with the red arrow
to increase temperature. Each time you press the button, a
red indicator light will come on. To decrease temperature,
press the button with the blue arrow. Each time you press
the button a blue indicator light will come on.
If the passenger control has been turned on, it can be
turned off by pressing the OFF button on the main
system once. (Pressing the OFF button a second time
will turn off the main system.)
Automatic Operation
Press the AUTO button when you want the system to
automatically maintain a selected temperature inside of
your vehicle. When the system is set for automatic
operation, air will come from the floor ducts, instrument
panel outlets or windshield outlets depending on the
temperature inside the vehicle, the outside temperature
and sun load. Fan speed and use of air conditioning and
recirculation will vary as needed.

3-7
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.

3-40 Theft-Deterrent Feature (If Equipped)
THEFTLOCK
is designed to discourage theft of your
radio. It works by using a secret code to disable all radio
functions whenever battery power is removed and the
radio is placed in a different vehicle. This feature
requires no user input to be activated. It is automatically
armed when it is put into the vehicle for the first time.
When the ignition is turned off, the blinking red light
indicates that THEFTLOCK is armed.
If THEFTLOCK is activated, your radio will not operate
if stolen. The radio will display LOCKED and a red
LED indicator light will come on above the key symbol
to indicate a locked condition. If this occurs, the radio
will have to be returned to the dealer.
Audio Steering Wheel Controls
(If Equipped)
If your vehicle has this feature, you can control certain
radio functions using the buttons on your steering wheel.
SOURCE: Press this button to play a cassette tape or
compact disc when listening to the radio. If a cassette
tape and a compact disc are both loaded, the system will
go to the tape play first.
MUTE: Press this button to silence the system. Press it
again to turn on the sound.
VOL
(Volume): Press the up or down arrow to
increase or decrease volume.

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).

3-43
When cleaning the cassette tape player with the
recommended non
-abrasive cleaning cassette, it is
possible that the cassette may eject, because the cut tape
detection feature on your radio may recognize it as a
broken tape. If the cleaning cassette ejects, insert the
cassette at least three times to ensure thorough cleaning.
You may also choose a non
-scrubbing action, wet-type
cleaner which uses a cassette with a fabric belt to clean
the tape head. This type of cleaning cassette will not
eject on its own. A non
-scrubbing action cleaner may
not clean as thoroughly as the scrubbing type cleaner.
The use of a non
-scrubbing action, dry-type cleaning
cassette is not recommended.
After you clean the player, press and hold the eject
button for five seconds to reset the CLEAN PLAYER
indicator. The radio will display
--- to show the
indicator was reset.
Cassettes are subject to wear and the sound quality
may degrade over time. Always make sure the cassette
tape is in good condition before you have your tape
player serviced.
Care of Your Compact Discs
Handle discs carefully. Store them in their original cases
or other protective cases and away from direct sunlight
and dust. If the surface of a disc is soiled, dampen a
clean, soft cloth in a mild, neutral detergent solution and
clean it, wiping from the center to the edge.
Be sure never to touch the signal surface when handling
discs. Pick up discs by grasping the outer edges or the
edge of the hole and the outer edge.
Care of Your Compact Disc Player
The use of CD lens cleaner discs is not advised, due to
the risk of contaminating the lens of the CD optics with
lubricants internal to the CD mechanism.

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.

4-9
Remember: Anti-lock doesn't 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 won't 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
anti
-lock brakes.
Using Anti
-Lock
Don't pump the brakes. Just hold the brake pedal
down firmly and let anti
-lock work for you. You may
feel a slight brake pedal pulsation or notice some noise,
but this is normal.
Braking in Emergencies
With anti-lock, 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
(If Equipped)
Your vehicle may have 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 front wheels are spinning or
beginning to lose traction. When this happens, the
system works the front brakes and reduces engine
power to limit wheel spin.
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
reengage the cruise control. See ªCruise Controlº
in the Index.

4-10
This light should come
on briefly when you start
the engine. If it stays on
or comes on while you
are driving, there's a
problem with your
traction control system.
See ªTraction Control System Warning Lightº in the
Index. When this warning light is 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 should turn the system off if your vehicle ever
gets stuck in sand, mud or snow and rocking the vehicle
is required. See ªRocking Your Vehicleº in the Index.
To turn the system off, press the TRACTION OFF
button located at the end of the shift lever on the right
side of the steering wheel.
The traction control system warning light will come
on and stay on. If the system is limiting wheel spin
when you press the button, the warning light will come
on
-- but the system won't turn off right away.
It will wait until there's no longer a current need to
limit wheel spin.
You can turn the system back on at any time by pressing
the button again. The traction control system warning
light should go off.
