AIR CONDITIONING (OPTIONAL) 1B-1
SECTION 1B
AIR CONDITIONING (OPTIONAL)
CAUTION:
The air conditioning system of this vehicle uses refrigerant CFC-12 (R-12).
None of refrigerant, compressor oil and component parts is interchangeable between two
types of A / C: one using refrigerant CFC-12 (R-12) and the other using refrigerant 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, refer to the description in page 1B-2.
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 oth-
er faulty condition.
For basic servicing method of the air conditioning system that is not described in this section, refer to AIR CONDI-
TIONING BASIC MANUAL (99520-02130).
