Control Operation
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.
TEMPERATURE SWITCH (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 (80% foot and 20% defrost) position. In the off position, the A/C system uses the
vehicle's ªflow throughº ventilation. It tries to maintain the interior temperature based on the last set tem-
perature of the system.

screen):
