Air Conditioner Controls (Option)

Controls" in this part. The incoming air is cooled and
dehumidified instead of being heated.
A/C: Push this button to change your comfort control
system from heating to air conditioning. A light will
come on when the air conditioning is on. The A/C
button can also control the humidity in your vehicle.
Cooling
The air conditioner works best if you keep your
windows closed. On very hot days, open the windows
just long enough for the hot air to escape.
Push the A/C button. Move the air intake lever to
CIRCULATE for normal cooling. For faster cooling
move the lever to RECIRCULATE. Then move the
airflow knob to VENT and turn the temperature control
knob counterclockwise. Turn the fan knob to HI.

On days when it is raining or the humidity is high,
follow these dehumidifying steps instead of the cooling
directions. It will help clean windows that are cloudy
with moisture.
Push the
A/C
button. Move the air intake lever to
CIRCULATE and turn the airflow knob to DEFROST.
Turn the fan knob to HI and adjust the temperature knob
to a comfortable setting.
