«ª(Driver’s Temperature Controls):Press the up
or down buttons closest to the driver to increase or
decrease the temperature inside the vehicle.
«ª(Passenger’s Temperature Controls):Press the
up or down buttons closest to the passenger to
increase or decrease the temperature for the front
passenger. If the passenger climate control system is
off, pressing either of these buttons turns it on.
Manual Operation
O(On/Off):Press to turn the climate control system on
or off. While off, adjusting any button or control,
except recirculation and rear window defog turns the
system back on. The air inlets default to outside
air when the climate control system is turned off.
9(Fan Control):Turn clockwise or counterclockwise
to increase or decrease the fan speed. The fan
speed remains at this speed until it is turned to AUTO
or adjusted to a different level. In the automatic position,
the blower might go to a lower speed during an
OnStar
®session to limit the background noise.Air Delivery Mode Control:
To change the current mode, select one of the following:
AUTO:Turns on the automatic delivery mode
operation.
F(Vent):Air is directed to the instrument panel outlets.
*(Bi-Level):Air is directed to the instrument panel
outlets and the oor outlets. The temperature of the air
to the oor will be warmer than the air to the upper
outlets.
7(Floor):Air is directed to the oor outlets with some
air directed to the outboard outlets, side window
outlets, and defroster outlet.
W(Defog):This mode clears the windows of fog or
moisture. Air is directed to the windshield and oor
outlets, with some air going to the outboard outlets and
side window outlets. When selected, the system
turns off recirculation and runs the air conditioning,
unless the outside temperature is at or below freezing.
If recirculation mode is selected while using the
defog mode, the system recirculates air for about
10 minutes and then returns to outside air mode.

0(Defrost):This mode clears the windshield of fog or
frost more quickly. Air is directed to the windshield
with some air going to the side window outlets. When
selected, the system turns off recirculation and runs the
air conditioning compressor, unless the outside
temperature is at or below freezing.
Do not drive the vehicle until all the windows are clear.
PASS (Passenger’s Climate Control):Press to
turn the passenger climate control system on or off.
Then press the passenger
«orªbuttons to adjust
the temperature. Pressing PASS again automatically
sets the passengers temperature to the drivers setting.
Turning off the passenger temperature display does
not turn off the passenger climate control system.
Air Inlet Modes
There are three options for bringing air into the climate
control system. They are controlled by pressing the
outside air button on the climate control panel.The climate control display indicates one of the
following three modes:
9(Auto Air Inlet):This mode lets the automatic
climate control system choose the best air inlet position
for cooling or warming the vehicle. To have full
automatic climate control, the fan and mode controls
must be set to the AUTO position. On hot days,
the recirculation mode may be selected automatically.
?(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.
The recirculation mode cannot be used with oor, defog,
or defrosting modes. Using recirculation for long periods
of time can cause the air inside the vehicle to become
too dry or stuffy. To prevent this from happening, after the
air in the vehicle has cooled, select auto air inlet or
outside air.
F(Outside Air):Air is pulled from outside the
vehicle. Outside air is always selected in defrost mode
to prevent fogging.

Air Conditioning
#
(Air Conditioning):Press to turn the air
conditioning on or off, and override the automatic
system. When selecting the AUTO fan or AUTO mode,
the air conditioning comes on automatically, as
necessary.
The air conditioning system removes moisture from the
air, so water might drip underneath the vehicle while
idling or after turning off the engine. This is normal.
Sensors
There is a solar sensor
located on top of the
instrument panel, near the
windshield.There is an interior
temperature sensor
located below the climate
control system next to
the steering wheel.
An ambient sensor is located behind the grille in front
of the vehicle.
These sensors help the climate control system
automatically control the temperature setting.
The system can supply cooler air to the side of the
vehicle facing the sun. The recirculation mode will also
be used as needed to maintain cool outlet temperatures.
Do not cover any of the sensors or the climate control
system might not work properly.

Rear Window Defogger
The rear window defogger uses a warming grid to
remove fog or frost from the rear window.
<(Rear Defogger):Press to turn the rear window
defogger on or off. The rear window defogger stays on
for about 20 minutes, before turning off. At higher
vehicle speeds, the rear defogger can stay on
continuously. Each additional press runs the defogger
for about 10 minutes.
When the rear window defogger is pressed, the heated
outside mirrors come on. They help to clear fog or
frost from the surface of the mirror. SeeOutside Heated
Mirrors on page 2-40.
Notice:Do not use a razor blade or sharp object
to clear the inside rear window. Do not adhere
anything to the defogger grid lines in the rear glass.
These actions may damage the rear defogger.
Repairs would not be covered by your warranty.
Outlet Adjustment
Use the knobs located in the center of each outlet to
change the direction of the air ow. Use the thumbwheels
to open or close the outlets.
Operation Tips
Clear away any ice, snow, or leaves from the air
inlets at the base of the windshield that could
block the ow of air into the 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 the vehicle more
effectively.
If the air ow seems low when the fan speed is at
the highest setting, the passenger compartment
air lter might need to be replaced. For more
information, seePassenger Compartment Air Filter
on page 3-28.
Set the climate control system to AUTO fan and
mode and then adjust the temperature setting
up or down a few degrees for best comfort.

Rear Air Conditioning System
For vehicles with the rear air conditioning system, it has
two fan speed selectors. One fan speed selector is
located in the front overhead console and the other is
located in the headliner above the second row seats.
The rear air conditioning system is designed to provide
cooled air only.
To operate the rear system
using the front control,
turn the knob to the
fan position desired.To use the rear control,
turn the front control to
AUX, then use the
rear control to increase
and decrease the air ow.
