AIR BAG WARNING

See AIR BAG SAFETY PRECAUTIONS .

A/C SYSTEM CAUTION

CAUTIONThe air conditioning system of this vehicle uses refrigerant HFC-134a (R-134a). None of the refrigerant compressor oil and component parts is interchangeable between tow types of A/C: one using refrigerant CFC-12 (R-12) and the other using HFC-134a (R-134a). Be sure to check which refrigerant is used before any service work including inspection and maintenance. For identification between these two types. See A/C SYSTEM INTRODUCTION . When replenishing or changing refrigerant and compressor oil and when replacing parts, make sure that the material or the part to be used is appropriate to the A/C installed in the vehicle being serviced. Use of incorrect one will result in leakage of refrigerant, damage in parts or other faulty condition.

The heater, an in and out air selectable-type hot water heater, is so constructed that it is possible to assure an agreeable ventilation at all times by providing the ventilator air outlets at the center and both sides (right and left) of the instrument panel, the hot air outlet at a place close to the feet of front passengers, and the defroster air outlets at places, right and left, along the windshield glass.

The heater and ventilation consist of the following parts.
