Operation
9
(Fan):Turn the left knob clockwise or
counterclockwise to increase or decrease the fan speed.
In any setting other than off, the fan runs continuously
with the ignition on. To turn off the air completely,
turn the fan to 0 and select the recirculation button.
Temperature Control:Turn the center knob clockwise
or counterclockwise to increase or decrease the
temperature inside the vehicle.
Use the right knob to select from the following modes:
There is one position between each mode to nely
adjust air ow position.
H(Vent):This mode directs air to the instrument
panel outlets.
)(Bi-Level):This mode splits the air between the
instrument panel outlets and the oor outlets.
6(Floor):This mode directs most of the air to the
oor outlets with some air directed to the windshield
and side windows.
The right knob may also be used to select the defrost
and defog modes that are described in this section.You can also select modes by using the following
buttons:
;(Outside Air):Press this button to turn the
outside air mode on. When this mode is on, outside air
will circulate throughout the vehicle. When the button
is pressed, an indicator light in the button comes on to
show that it is activated. The outside air mode can
be used with all modes, but it cannot be used with the
recirculation mode.
@(Recirculation):Press this button to recirculate
cabin air through the vehicle. It can be used to prevent
outside air and odors from entering the vehicle or to help
heat or cool the air inside the vehicle more quickly. An
indicator light will come on in this mode. Operation in this
mode during periods of high humidity and cool outside
temperatures may result in increased window fogging. If
window fogging is experienced, select the defrost mode.
The recirculation mode cannot be used with oor, defrost,
or defogging modes. If you try to select recirculation in
one of those modes, the indicator light ashes several
times and turns off.

#(Air Conditioning):Press this button to turn the air
conditioning system on or off. When this button is
pressed, an indicator light on the button comes on to
show that the air conditioning is activated. The air
conditioning can be selected in any mode as long as
the fan switch is on.
The air conditioning compressor does not operate when
outside temperatures fall below 38°F (3°C). The
indicator light ashes several times and turns off when
outside conditions affect air conditioning operation.
This is normal.
On hot days, open the windows to let hot inside air
escape; then close them. This helps to reduce the time
it takes for the vehicle to cool down. It also helps the
system to operate more efficiently.For quick cool down on hot days, select the following
settings together:
1. Vent mode.
2. Outside air.
3. Air conditioning.
4. The coolest temperature.
5. The highest fan speed.
6. Once the vehicle’s interior temperature is below the
outside temperature, select recirculation mode for
enhanced cooling.
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 inside of
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 underneath
the vehicle while idling or after turning off the engine.
This is normal.
((Heated Seats):If your vehicle has heated seats,
seeHeated Seats on page 1-4.

Defogging and Defrosting
Fog or frost 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.
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. When either of these modes are selected, the
system runs the air conditioning compressor and cancels
the recirculation mode to dry the air. For best results,
clear all snow and ice from the windshield before
defrosting.
Turn the right knob to select the defog or defrost mode.
-(Defog):This mode directs half of the air to the
windshield and the side window outlets, and half to the
oor outlets.
0(Defrost):This mode directs most of the air to the
windshield and the side window outlets, with some
air directed to the oor outlets.
Rear Window Defogger
The rear window defogger uses a warming grid to
remove fog from the rear window.
The rear window defogger only works when the ignition
is in ON/RUN.
<(Rear):Press this button to turn the rear window
defogger on or off. An indicator light on the button comes
on to show that the rear window defogger is activated.
The rear window defroster stays on for about 10 minutes
if the vehicle remains at slower vehicle speeds or until
the button is pressed, or unless the ignition is turned
to ACC/ACCESSORY or LOCK/OFF. If turned on again,
the defogger only runs for about ve minutes before
turning off again. At higher vehicle speeds, the defogger
may stay on continuously. The defogger can always
be turned off by pressing the button again or by turning
off the ignition.

If your vehicle has the remote start feature, the rear
defogger automatically turns on if it is cold outside.
When the vehicle transitions out of the remote start
mode, the rear defogger will turn off. SeeRemote
Keyless Entry (RKE) System Operation on page 2-5.
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.
Remote Start Climate Control Operation
If your vehicle has the remote start feature and it
is activated, the climate control system heats and cools
the inside of the vehicle using the modes that were
set before the vehicle was turned off and the rear
defogger automatically turns on. If your vehicle has
heated seats, they may turn on if it is cold outside
and will shut off when the key is turned to ON/RUN.
SeeHeated Seats on page 1-4.
Outlet Adjustment
Use the louvers located on the air outlets 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 vehicle that may block
the ow of air into your vehicle.
Do not use any non-GM approved hood de ectors
that could 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.
Passenger Compartment Air Filter
Outside air is routed through a passenger compartment
air lter before entering the vehicle. This lter removes
certain particles from the air, including pollen and
dust particles. Reductions in air ow, which may occur
more quickly in dusty areas, indicate that the lter needs
to be replaced early.
The lter should be replaced as part of routine
scheduled maintenance. SeeScheduled Maintenance
on page 6-4for when to replace the lter.
