Fan Knob
9
(Fan):The center knob on the control panel is used
to control the fan speed. Turn the knob clockwise or
counterclockwise to increase or decrease the fan speed.
If the knob is set on “0” (zero), some outside air will still

air ow inside your vehicle. Turn the knob to select
one of the following modes:
H(Vent):Select this mode to direct air to the
instrument panel outlets.
\(Bi-Level):Select this mode to direct approximately

remaining air to the oor outlets and the defroster
and side window outlets. Cooler air is directed to the
upper outlets and warmer air to the oor outlets.
[(Floor):Select this mode to direct air to the oor
outlets. Enabling recirculation in heat mode may
cause interior window fogging under some conditions.
If this occurs, see “Defogging and Defrosting” following.
Mode Buttons
@
(Recirculation):If your vehicle has air
conditioning, you will have the recirculation feature.
This mode recirculates air inside the cabin, and prevents
outside air from coming in the vehicle. It can be used
to prevent outside odors from entering your vehicle and
cool the air inside your vehicle more quickly. Press this
button to turn the recirculation mode on or off.
An indicator light on the button will come on to let you
know the recirculation mode is activated.
Recirculation is available in the bi-level, vent and oor
(heat) modes. It should only be used while in bi-level
and vent modes. Recirculation is not available, and
the light will not come on, while in oor/defog or
defrost modes.
#(Air Conditioning):Your vehicle may have air
conditioning. Press this button to turn the air-conditioning
system on or off. An indicator light on the button will
come on to let you know the air conditioning is activated.
When the system is on, this setting cools and
dehumidi es the air entering your vehicle.
The air conditioning will not function if the fan is
turned off.
You may notice a slight change in engine performance
when the air conditioning compressor shuts off and
turns on again. This is normal. The system is designed
3-20
to make adjustments to help with fuel economy while
still maintaining the selected temperature.
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 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 and side windows. 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.
For best results, clear all snow and ice from the
windshield before defrosting.
Turn the mode knob on the climate control panel
clockwise to select the defog or defrost modes.
/(Floor/Defog):This mode directs the air to the
windshield, the side window outlets, and to the
oor outlets. When you select this mode, the system
runs the air conditioning compressor unless the outside
temperature is near freezing or below. Recirculation
is not available in this mode.
0(Defrost):This mode directs most of the air to the
windshield, and the side window outlets. When you
select this mode, the system runs the air conditioning
compressor 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.
Outlet Adjustment
Use the thumbwheel on the outlets to change the
direction of the air ow.
Lift up or push down on the thumbwheel located in the
center of the outlet to direct the air up or down, or
slide the thumbwheel to the left or right to direct the
air ow from side-to-side.
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 of your vehicle more
effectively.
