Clock
There is a digital clock located in the center of the
instrument panel, above the center air outlets. When the
ignition is turned to ACC/ACCESSORY or ON/RUN,
the time is displayed in the digital clock. There are
three buttons for adjusting the digital clock:
H (Hour):Press once to go forward one hour. To go
forward more than one hour, press and hold the button
until the correct hour is reached.
M (Minute): Press once to go forward one minute. To go
forward more than one minute, press and hold the
button until the correct minute is reached.
S (Set): Press to reset the time to the nearest hour.
For example, if the set button is pressed while the time
is between 8:00 and 8:29, the display is set to 8:00.
If this button is pressed while the time is between
8:30 and 8:59, the display is set to 9:00.
After disconnecting the battery or replacing the fuse,
reset the clock.

OFF : Turns the fan off.
Temperature Control : Turn clockwise or
counterclockwise to increase or decrease the
temperature of the air flowing from the system.
9 (Fan Control) : Turn clockwise or counterclockwise
to increase or decrease the fan speed. The fan must be
turned on to run the air conditioning compressor. Air Delivery Mode Control :
Turn clockwise or
counterclockwise to change the current airflow mode.
Select from the following air delivery modes:
Y (Vent) : Air is directed to the instrument panel
outlets.
\ (Bi-Level) : Air is divided between the instrument
panel and floor outlets.
[ (Floor) : Air is directed to the floor outlets, with
some air directed to the rear outlets. Keep the area
under the front seats clear to allow the flow of air to the
rear compartment.
É(Defog) : This mode clears the windows of fog or
moisture. Air is directed to the windshield, floor, and
side window outlets. When this mode is selected, the
system automatically runs the air-conditioning. To defog
the windows faster, turn the temperature control to the
warmest setting.
1 (Defrost) : This mode quickly clears the windshield
of fog or frost. Air is directed to the windshield and side
window outlets. When this mode is selected, the system
automatically runs the air-conditioning. To defrost the
windows faster, turn the temperature control to the
warmest setting.
Do not drive the vehicle until all the windows are clear.

A/C (Air Conditioning) :For vehicles with air
conditioning, follow these steps to use the system.
Turn
9to the desired speed. The air conditioning does
not operate when the fan control knob is in the off
position. Press A/C to turn the air conditioning on and
off. When A/C is pressed, an indicator light comes on to
show that the air conditioning is on.
For quick cool down on hot days, do the following:
1. Open the windows to let hot air escape.
2. Press
?.
3. Press A/C.
4. Select the coolest temperature.
5. Select the highest
9speed.
Using these settings together for long periods of time
may cause the air inside of the vehicle to become too
dry. To prevent this from happening, after the air in the
vehicle has cooled, turn the recirculation mode off.
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) : 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.
For vehicles with a recirculation button, press the button
to turn the recirculation mode on. An indicator light
comes on to show that the recirculation is on. Press the
button again to return to outside air mode.
For vehicles with a lever, move the lever to choose the
recirculation mode.
Using the recirculation mode for extended periods may
cause the windows to fog. If this happens, select the
defrost mode.
: (Outside Air) : This mode brings outside air into
the vehicle.
For vehicles with a recirculation button, press the button
until the recirculation mode is turned off. The vehicle
then returns to the outside air mode.
For vehicles with a lever, move the lever to choose the
outside air mode.

Rear Window and Outside Mirror
Defogger
For vehicles with a rear window and outside mirror
defogger, they only work when the ignition is turned
to ON/RUN.
The rear window defogger uses a warming grid to
remove fog or frost from the rear window.
<(Rear Window Defogger) : Press to turn the rear
window and outside mirror defogger on or off. An
indicator light comes on to show that the feature is on.
If the vehicle does not have air conditioning, the rear
window defogger may turn off about 10 minutes after
the button is pressed. If it remains on, it can be turned
off by pressing
If the vehicle has air conditioning, the rear window
defogger turns off about 10 minutes after the button is
pressed. The defogger can also be turned off by turning
the engine off.
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
To open an outlet, press on its cover. Turn the cover to
change the direction of the airflow.
Operation Tips
.Clear away any ice, snow or leaves from the air
inlets at the base of the windshield that may block
the flow of air into the vehicle.
.Use of non-GM approved hood deflectors 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.
Passenger Compartment Air Filter
For vehicles with a passenger compartment air filter, it
is located behind the glove box. It can be accessed
after removing the glove box from its housing.
Pollen and dust are removed by the filter. The filter
should be replaced as part of routine scheduled
maintenance. For a replacement filter see your dealer/
retailer. See Scheduled Maintenance
on page 7‑3for
replacement intervals.

WARNING: (Continued)
If you keep driving when your engine is
overheated, the liquids in it can catch fire. You or
others could be badly burned. Stop your engine if
it overheats, and get out of the vehicle until the
engine is cool.
If No Steam Is Coming From The
Engine Compartment
If an engine overheat warning is displayed but no steam
can be seen or heard, the problem may not be too
serious. Sometimes the engine can get a little too hot
when the vehicle:
.Climbs a long hill on a hot day.
.Stops after high-speed driving.
.Idles for long periods in traffic.If the overheat warning is displayed with no sign of
steam:
1. Turn the air conditioning off.
2. Turn the heater on to the highest temperature and to the highest fan speed. Open the windows as
necessary.
3. If in a traffic jam, let the engine idle in N (Neutral) while stopped. If it is safe to do so, pull off the
road, shift to P (Park) or N (Neutral) and let the
engine idle.
If the temperature overheat gage is no longer in the
overheat zone or an overheat warning no longer
displays, the vehicle can be driven. Continue to drive
the vehicle slow for about 10 minutes. Keep a safe
vehicle distance from the car in front of you. If the
warning does not come back on, continue to drive
normally.
If the warning continues, pull over, stop, and park the
vehicle right away.
If there is no sign of steam, idle the engine for
three minutes while parked. If the warning is still
displayed, turn off the engine until it cools down.
