Automatic Operation
AUTO9(Automatic Fan): When this position is
selected on the fan control, the system adjusts the fan
speed. To use automatic operation:
1. Turn the fan control to the AUTO position.
2. Turn the air delivery mode to the AUTO position.
3. Adjust the temperature to a comfortable setting between 21°C (68°F) and 26°C (78°F).
Choosing the coldest or warmest temperature
setting will not cause the system to heat or cool
any faster. In cold weather, the system will start
at reduced fan speeds to avoid blowing cold air
into the vehicle until warmer air is available. The
system starts out blowing air at the floor but may
change modes automatically as the vehicle warms
up to maintain the chosen temperature setting. The
length of time needed to warm the interior depends
on the outside temperature and temperature of the
vehicle.
4. Wait 20 to 30 minutes for the system to stabilize in order for the system to regulate automatically.
Then adjust the temperature as necessary to find
your comfort setting.
Do not cover the solar sensor located in the center of
the instrument panel near the windshield. For more
information on the solar sensor, see “Sensors”later in
this section.
After the vehicle is started, the display shows the
interior temperature settings and the outside
temperature.

If the AUTO position is selected on the fan or mode
control, the system automatically controls the air
conditioning compressor. The A/C compressor will run
automatically even at cool outside temperatures in order
to dehumidify the air. The A/C indicator light is lit when
the system is operating automatically, even at near
freezing outside temperatures. Press
#on the fan
control to turn off the A/C. For improved window
clearing performance in defog or defrost modes, the
A/C compressor runs automatically.
h(AUTO RECIRCULATION): If the AUTO position is
selected on either the fan or air delivery mode control,
the system automatically controls the air inlet to supply
fresh outside air or recirculate the interior air to cool the
car faster. The light on the recirculation button will come
on when the system changes to recirculation. Outside
air can be forced by pressing
hwhen the light is lit.
For vehicles without rear climate controls, press
:to
force outside air. The next time AUTO fan or mode is
selected, the air inlet will reset back to AUTO operation.

Air Delivery Mode Control:Turn clockwise or
counterclockwise to change the current airflow 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 divided between the instrument
panel and the floor outlets. In automatic operation,
cooler air is directed to the upper outlets and warmer air
to the floor outlets.
7 (Floor): Air is directed to the floor outlets with
some air directed to the side window outlets and the
windshield.
If recirculation is selected, it only stays on for
three minutes to reduce windshield fogging.
W(Floor/Defog): This mode clears the windows of
fog or moisture. Air is directed to the floor outlets,
with some air going to the side window outlets and
windshield. When selected, the system turns off
recirculation and runs the air conditioning compressor
unless the outside temperature is at or below freezing.
The recirculation mode cannot be selected while in the
floor/defog mode.
0(Defrost): This mode clears the windshield of fog
or frost more quickly. Air is directed to the windshield
and side window outlets. When selected, the system
automatically turns off recirculation and runs the
air conditioning compressor, unless the outside
temperature is at or below freezing. Recirculation
cannot be selected while in the defrost mode. Do not
drive the vehicle until all the windows are clear.
For professional vehicles, air will be allowed to flow
through the rear outlets. For quicker defrost, press the
AUX button on the front climate control system so that
the light is not lit.
#(Air Conditioning): Press to turn the air
conditioning system on or off and override the
automatic system. When in AUTO, the air conditioning
compressor comes on automatically, as necessary.
To avoid window fogging on rainy and humid days at
temperatures above freezing, run the air conditioning.
The air conditioning system removes moisture from
the air, so a small amount of water may drip under the
vehicle while idling or after turning off the engine. This
is normal.

In order to prevent false temperature readings at
startup, the displayed temperature will not change until
the following occurs:
.Vehicle speed is above 16 km/h (10 mph) for
5 minutes.
.Vehicle speed is above 51 km/h (32 mph) for 2 and
a half minutes.
The climate control system uses the information from
these sensors to maintain your comfort setting by
adjusting the outlet temperature, fan speed, and the
air delivery mode. The system may also 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.
Outlet Adjustment
For the front outlets, use the thumbwheel located below
each outlet to change the direction of the airflow. Use
the thumbwheel located next to the outlets to shut the
airflow or to open the outlets and re-direct the air.
For the rear outlets, slide the lever left or right and up or
down 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 your 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 your
vehicle more effectively.
Rear Climate Control System
For vehicles with a rear climate control system, the rear
seat passengers can adjust the direction of the airflow,
fan speed and temperature for the rear seating area.
