The heating, cooling, and ventilation for the vehicle can be controlled with this system.

(Fan Control): Turn clockwise or
counterclockwise to increase or decrease the fan speed. Turning the fan control
to 0 turns the fan off. The fan must be turned on to run the air conditioning compressor.
Temperature Control: Turn clockwise or counterclockwise to increase or decrease the temperature.
Air Delivery Mode Control: Turn clockwise or counterclockwise to change the current airflow mode.
Select from the following air delivery modes:
(Vent): Air is directed to the instrument
panel outlets.
(Bi-Level): Air is divided between
the instrument panel and floor outlets.
(Floor): Air is directed to the floor
outlets.
(Defog): This mode clears the windows
of fog or moisture. Air is directed to the floor, windshield, and side window outlets.
(Defrost): This mode clears the
windshield of fog or frost more quickly. When the defrost mode is selected, the
recirculation mode is set to outside air mode automatically. Air is directed to
the windshield and side window outlets.
Do not drive the vehicle until all windows are clear.
(Air Conditioning): Turn
to the desired speed. The air conditioning
does not operate when the fan control knob is at 0. Press
to turn the air conditioning on and
off. When
is pressed, an indicator
light comes on to show that the air conditioning is on.
Using air conditioning and recirculation together for long periods of time may cause the air inside the vehicle to become too dry. To prevent this from happening, after the air in the vehicle has cooled, turn the recirculation mode off.
(Recirculation): This mode recirculates
and helps to quickly cool the air inside the vehicle. It can be used to reduce the
entry of outside air and odors.
Press the button to turn the recirculation mode on. An indicator light comes on to show that the recirculation is on. Press the button again to return to outside air mode.
Using the recirculation mode for extended periods may cause the windows to fog. If this happens, select the defrost mode.
Rear Window Defogger
(Rear Window Defogger):
Press to turn the rear window defogger on or off. An indicator light comes on to show that the feature is on.
The defogger turns off if the ignition is turned to ACC/ACCESSORY or LOCK/OFF.
Caution
Using a razor blade or sharp object on the inside rear window can damage the antenna or defogger. Repairs would not be covered by the vehicle warranty.
Do not stick anything to the rear window.
