Instrument Panel 3-19

[(Floor):Air is directed to the
oor outlets, side window outlets,
and defroster. Recirculation is
not available in this mode.
/(Floor/Defog):This mode clears
the windows of fog and moisture.
Air is directed to the windshield, side
window, and oor outlets. The
system runs the air conditioning
unless the outside temperature is
near freezing or below. Recirculation
is not available in this mode.
0(Defrost):This mode clears
the windshield of fog or frost
more quickly. Air is directed to the
windshield and side window
outlets. The system runs the air
conditioning system unless
the outside temperature is near or
below freezing. Recirculation is
not available in this mode.
Do not drive the vehicle until all the
windows are clear.
#(Air Conditioning):Press to
turn the air conditioning system on
or off. An indicator light comes
on when the air conditioning
is turned on. This system cools and
dehumidies the air entering the
vehicle.
The air conditioning will not function
if the fan is turned off. If air
conditioning is selected with fan off,
the indicator light ashes three
times and then turns off.
A slight change in engine
performance may occur when the
air conditioning compressor shuts off
and turns on again. This is normal.
The system is designed to make
adjustments to help with fuel
economy while still maintaining the
selected temperature.
The air conditioning system removes
moisture from the air, so a small
amount of water might drip
under the vehicle while idling or
after turning off the engine. This is
normal.@(Recirculation):Press to turn
the recirculation mode on or off. An
indicator light comes on when the
recirculation is on. This mode
recirculates and helps to quickly cool
the air inside the vehicle. It can be
used to prevent outside air and odors
from entering the vehicle.
Recirculation is available in the
bi-level and vent modes. This mode
cannot be selected while in the oor,
oor/defog or defrost modes. If you
try to select the recirculation mode,
the indicator ashes three times
indicating it is not available in that
mode. When the recirculation mode
is turned on, the air conditioning
turns on automatically.
When it is hot enough outside, the
recirculation mode may turn on
automatically to help improve cooling
performance. The indicator light will
be lit to show this mode is active. If
the recirculation button is pressed
while in this mode, the light ashes
three times and stays on to indicate
that recirculation may not be shut off.

Rear Window Defogger
The rear window defogger uses a
warming grid to remove fog or
frost from the rear window when the
key is in the ignition and turned
to ON/RUN.
=(Rear Defogger):Press to turn
the rear window defogger on or
off. After the button is rst pressed
the rear window defogger stays
on for about 15 minutes. If turned on
again, the defogger only runs for
about seven and one-half minutes.
Notice:Do not use anything
sharp on the inside of the rear
window. If you do, you could cut
or damage the warming grid, and
the repairs would not be covered
by the vehicle warranty. Do not
attach a temporary vehicle
license, tape, a decal or anything
similar to the defogger grid.
Outlet Adjustment
Use the air outlets located in the
center and on the side of the
instrument panel to direct the
airow.
This vehicle has air outlets that
allow you to adjust the direction and
amount of airow inside the
vehicle. Move the louvers up or
down to change the direction of the
airow. Use the thumbwheel
under the outlets to change the
direction of the airow from left
to right.Operation TipsUse the recirculation mode for
maximum air conditioning
performance.
Clear away any ice, snow or
leaves from the air inlets at
the base of the windshield that
may block the ow of air into the
vehicle.
Use of non-GM approved hood
deectors may adversely affect
the performance of the system.
Keep the path under the
front seats clear of objects to help
circulate the air inside of the
vehicle more effectively.

Warning Lights,
Gages, and Indicators
Warning lights and gages can
signal that something is wrong
before it becomes serious enough
to cause an expensive repair or
replacement. Paying attention to the
warning lights and gages could
prevent injury.
Warning lights come on when there
may be or is a problem with one
of the vehicle’s functions. Some
warning lights come on briey when
the engine is started to indicate
they are working.
Gages can indicate when there may
be or is a problem with one of the
vehicle’s functions. Often gages and
warning lights work together to
indicate a problem with the vehicle.When one of the warning lights
comes on and stays on while
driving, or when one of the gages
shows there may be a problem,
check the section that explains what
to do. Follow this manual’s advice.
Waiting to do repairs can be
costly and even dangerous.
