Heating and Air Conditioning: Description and Operation

The heater system uses a two-way-flow full-air-mix system that features high performance and low operating noise, and includes an independent face air blowing function and a cool air bypass function. The A/C refrigerant system is basically the same as conventional systems and R134A refrigerant has been adopted as a response to restrictions on the use of chlorofluorocarbons. For the air conditioning switch, push-button controls have been adopted for air flow control, air conditioning mode switching and blower speed. When the button is depressed, the air flow direction, air conditioning mode and blower speed are indicated on a graphic display. A rotary control is used for setting cabin temperature. When the knob is rotated, the desired temperature is indicated on the graphic display.
