Description of Auto A/C Features

Automatic Temperature Controls:

AUTO SWITCH
The compressor, air intake doors, air mix door, mode doors, and blower speed are automatically controlled so that the in-vehicle temperature will reach, and be maintained at the set temperature selected by the operator.
The air conditioning cooling function operates only when the engine is running.

ECON SWITCH
Fully automatic control with the compressor off. With the compressor off, the system will not remove heat (cool) or de-humidify. The system will maintain the in-vehicle temperature at the set temperature when the set temperature is above the ambient (outside) temperature.

PTC (Potentio Temperature Control)
Increases or decreases the set temperature.

OFF SWITCH
The compressor and blower are off, the air intake doors are set to the outside air position. Then, the mode doors are set to the foot (78% foot and 22% defrost) position. In the off position the Automatic Temperature Control (ATC) system uses the vehicle's "flow through" ventilation. It tries to maintain the interior temperature based on the last set temperature of the system.

FAN SWITCH
Manual control of the blower speed. Four speeds are available for manual control (as shown on the display screen): low, medium low, medium high, high

MODE SWITCH
Manual control of the air discharge outlets. Four selections are available (as shown on the display screen): face, bi-level, foot, defrost/foot

REC SWITCH
ON position: Interior air is recirculated inside the vehicle.
OFF position: Automatic control resumes.
RECIRC is cancelled when AUTO, DEF or F/D is selected. RECIRC resumes when another mode is chosen.

DEF SWITCH
Positions the mode doors to the defrost position. Also positions the air intake doors to the outside air position. The compressor operates at ambient temperature approx. 2°C (35°F) or above.
