dust, and to cool the interior rapidly upon initial
start up in very hot or humid weather.
NOTE:
• Continuous use of the recirculation mode
may make the inside air stuffy and window
fogging may occur. Extended use of this
mode is not recommended.
• The use of the recirculation mode in cold or
damp weather will cause windows to fog on
the inside, because of moisture build-up
inside the vehicle. Select the Outside Air
position for maximum defogging.
• The A/C will engage automatically to prevent
fogging when the recirculation button is
pressed and the mode control is set to panel
or panel/floor.
• The A/C can be deselected manually without
disturbing the mode control selection.

Automatic Temperature Control
(ATC) — If Equipped
Automatic Operation
The Infrared Climate Control System automatically
maintains the climate in the cabin of the vehicle at
the comfort levels desired by the driver and
passenger. To accomplish this, the system gath-
ers information from the cabin infrared sensor
mounted between the sun-visors and from various
sensors located throughout the vehicle.
The controls on the climate control provide the
system with operator input. Other sensors take
account of vehicle speed, A/C pressure, outside
temperature, and engine cooling temperature.
Using all of these inputs, the system automatically
adjusts airflow temperature, airflow distribution,
airflow volume, and the amount of outside air
recirculation. This maintains a comfortable tem-
perature even under changing conditions.
Operation of the system is quite simple.
1. Turn the Mode Control knob (on the right) and
the Blower Control knob (on the left) to AUTO.
NOTE:
The AUTO position performs best for front seat
occupants only.
2. Dial in the temperature
you would like the system
to maintain by rotating the
Temperature Control knob.
