Mode Buttons
You may choose the direction of air delivery by
selecting one of the five mode control buttons.
PANEL: This setting directs airflow through the
upper air outlets located in the instrument panel.
BI-LEVEL: This setting directs airflow through
both the upper air outlets and the lower floor outlets.
There is also a small amount of air directed to the front
defroster and the side window defrosters.
FLOOR: This setting directs most of the airflow
to the lower floor outlets with some airflow directed to
the side window defrosters. There is also a small amount
of airflow directed to the front defroster.
DEFOG: This setting directs most of the airflow
to the lower floor outlets and the front windshield
defroster. A small amount of airflow is directed to the
side window defroster outlets. This mode can be useful
to remove the moisture from the inside of the windshield
when the outside temperature is cold or the humidity
is high.
FRONT: This setting directs most of the airflow
to the front windshield defroster with some airflow to
the side window defrosters and lower floor outlets.
To improve windshield clearing performance when you
select FRONT defrost, your air conditioning compressor
will run automatically above approximately 40
F (4
C).
This dehumidifies the air to help dry the windshield.
Even though the compressor may be running, the A/C
light will not come on in FRONT defrost unless you
select A/C.
Recirc Button
RECIRC: Press this button to limit the amount
of outside air entering your vehicle. This is helpful when
you are trying to quickly cool the interior of the vehicle
or to limit odors entering the vehicle. RECIRC may be
selected in all manual airflow modes except FRONT
defrost. If you select RECIRC while in defrost, the
RECIRC light will flash to let you know that this is
not allowed. This is to help prevent fogging.

A/C: Press this button to turn the air conditioning
compressor on and off. When A/C is selected or in
AUTO mode, the system will run the A/C automatically

select A/C OFF while in FRONT defrost, the A/C OFF
text will flash to let you know this is not allowed. This is
to prevent fogging.

of outside air entering your vehicle. You may use this
setting to limit odors entering your vehicle. Press

rear window warm the
glass. Press the button to
start warming your window.
A light will glow in the
button while the defogger
is working.
If your vehicle is equipped with heated mirrors, this
button will activate them.
After 10 minutes it will turn off by itself, or press the
button during the heating cycle to turn it off. If you need
additional warming time, push the button again. The
system will then operate for five minutes before turning
off by itself. If your speed is maintained over 30 mph
(48 km/h), the rear defog will not turn off automatically
to help keep the rear glass clear.
Do not attach a temporary vehicle license, tape or decals
across the defogger grid on the rear window.NOTICE:
Do not try to clear frost or other material from
the inside of the rear window with a razor blade
or anything else that is sharp. This may damage
the defogger grid. The repairs wouldn't be
covered by your warranty.
Ventilation System
For mild outside temperatures when little heating or
cooling is needed, use the panel outlet setting (on the
standard system) to direct outside air through your
vehicle. Air will flow through the instrument
panel outlets.
Your vehicle's flow

outside air into the vehicle when it's moving. When the
vehicle is not moving, you can get outside air to flow
through by selecting any air delivery mode and any
fan speed.

3-43 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 dealership (GM Part No. 12344789).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 EJECT for
two seconds to reset the CLEAN PLAYER indicator.
The radio will display CLEANED 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.
