HEATER, VENTILATION AND AIR CONDITIONING

id070000700000

Features

• HFC-134a has been adopted as the new refrigerant.

• A variable displacement, swash plate type A/C compressor has been adopted which increases or decreases the quantity of refrigerant compression depending on the vehicle conditions.

• A dash-electrical supply unit has been adopted which controls the air conditioner system.

• A dash-electrical supply unit built into the blower fan controller has been adopted.

• LIN communication control has been adopted for control of the air intake actuator, air mix actuator, and the mode actuator.

• A touch panel climate control unit has been adopted.

• A climate control unit has been adopted with which the airflow temperature setting for the driver and passenger sides can each be adjusted independently.
