:(Outside Air):Press this button to turn on
outside air. When this mode is on, outside air
will circulate throughout your vehicle. When the
button is pressed, an indicator light will come on to
show that it is on.
?(Recirculation):Press this button to turn on
the recirculation mode. When the button is
pressed, an indicator light will come on to show
that it is on.
This mode keeps outside air from entering the
vehicle. It can be used to prevent outside air and
odors from entering your vehicle. Recirculation
may also help heat or cool the air inside your
vehicle more quickly once the temperature inside
the vehicle is equal to or better than the outside
temperature. The recirculation mode cannot
be used with outside air, oor, defrost, or
defogging modes.
Temperature Control:Turn the thumbwheels up
or down to increase or decrease the temperature
on the driver’s side or the passenger side of
the vehicle for the dual zone system. Turn the
center knob clockwise or counterclockwise
to increase or decrease the temperature for the
single zone system.
#(Air Conditioning):Press this button to turn
the air conditioning system on or off. When
A/C is pressed, an indicator light will come on to
let you know that the air conditioning is on.
On hot days, open the windows to let hot inside
air escape; then close them. This helps to reduce
the time it takes for your vehicle to cool down.
It also helps the system to operate more efficiently.
For quick cool down on hot days, do the following:
1. Select the vent mode.
2. Select A/C.
3. Select the coolest temperature for both zones.
4. Select the highest fan speeds.
5. When the coolest temperature is selected in
the A/C mode, the system will automatically
go into the recirculation mode to improve
cooling. Press the Outside Air or Recirculation
button to turn off the automatic recirculation.
This feature will stay off until the climate
control system is powered on again or the
vehicle has been turned off and on again.

Using these settings together for long periods of
time may cause the air inside of your vehicle
to become too dry. To prevent this from
happening, after the air inside of your vehicle has
cooled, turn the recirculation mode off.
The air conditioning system removes moisture
from the air, so you may sometimes notice a small
amount of water dripping underneath your
vehicle while idling or after turning off the engine.
This is normal.
Defogging and Defrosting
Fog on the inside of the windows is a result of
high humidity (moisture) condensing on the
cool window glass. This can be minimized if the
climate control system is used properly. There are
two modes to clear fog or frost from your
windshield. Use the defog mode to clear the
windows of fog or moisture and warm the
passengers. Use the defrost mode to remove
fog or frost from the windshield more quickly.Do not drive the vehicle until all the windows
are clear.
Turn the right knob clockwise to select the defog
or defrost mode.
-(Defog):This mode directs air equally to the
windshield and the oor outlets. When defog
is selected, the system turns off recirculation and
runs the air conditioning compressor unless
the outside temperature is below 40°F (4°C).
0(Defrost):This mode directs most of the air to
the windshield with some air to the side window
vents and the oor vents. When defrost is selected,
the system will automatically force outside air into
the vehicle. The air conditioning compressor will run
automatically in this setting, unless the outside
temperature is below 40°F (4°C).

Rear Window Defogger
The rear window defogger uses a warming grid to
remove fog from the rear window.
<:The rear window defogger will turn off
automatically after it has been activated for
10 minutes. It can be turned off manually, by
pressing the button again or by turning the ignition
to the OFF position. If additional window clearing
is required, the rear window defogger can be
turned on again for additional window clearing. The
length of defogger operation will increase if the
vehicle is being driven.
If your vehicle has heated outside rearview
mirrors, the mirrors will heat to help clear fog or
frost from the surface of the mirror when the
rear window defog button is pressed. SeeOutside
Power Mirrors on page 124.
Do not drive the vehicle until all the windows
are clear.
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 your warranty. Do not
attach a temporary vehicle license, tape, a decal
or anything similar to the defogger grid.
Outlet Adjustment
Use the knob located below or to the side of the
outlet, to change the direction of the air ow.
Operation Tips
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 your vehicle.
Use of non-GM approved hood de ectors may
adversely affect the performance of the system.
Keep the path under the front seats clear of
objects to help circulate the air inside your
vehicle more effectively.
If the air ow seems low when the fan is at the
highest setting, the passenger compartment air
lter, if equipped, may need to replaced. For
more information, seePassenger Compartment
Air Filter on page 169andScheduled
Maintenance on page 406.

When the ignition is on, the brake system warning
light will also come on when you set your
parking brake. The light will stay on if your parking
brake does not release fully. If it stays on after
your parking brake is fully released, it means you
have a brake problem.
If the light comes on while you are driving, pull off
the road and stop carefully. You may notice that the
pedal is harder to push or, the pedal may go closer
to the oor. It may take longer to stop. If the light is
still on, have the vehicle towed for service. See
Brake System Warning Light on page 177and
Towing Your Vehicle on page 282.
{CAUTION:
Your brake system may not be working
properly if the brake system warning light
is on. Driving with the brake system
warning light on can lead to an accident.
If the light is still on after you have pulled
off the road and stopped carefully, have
the vehicle towed for service.
Anti-Lock Brake System
Warning Light
If your vehicle is
equipped with anti-lock
brakes, the anti-lock
brake system warning
light should come on for
a few seconds when
you turn the ignition
key to RUN.
If the anti-lock brake system warning light stays on
longer than normal after you’ve started your
engine, turn the ignition off or, if the light comes
on and stays on when you are driving, stop
as soon as possible and turn the ignition off. Then
start the engine again to reset the system. If
the light still stays on, or comes on again while
you are driving, the anti-lock brake system needs
service and you do not have anti-lock brakes.
The anti-lock brake system warning light should
come on brie y when you turn the ignition
key to RUN. This is normal. If the light does not
come on then, have it xed so it will be ready
to warn you if there is a problem.
