Fig. 24: Climate Control System Operation 

This vehicle uses HFC-134a (R-134a) refrigerant which does not contain chlorofluorocarbons. Pay attention to 
the following service items:  

z

Do not mix refrigerants CFC-12 (R-12) and HFC-134a (R-134a). They are not compatible.  

z

Use only the recommended polyalkyleneglycol (PAG) refrigerant oil (KEIHIN SP-10) designed for the 
R-134a compressor. Intermixing the recommended (PAG) refrigerant oil with any other refrigerant oil 
will result in compressor failure.  

z

All A/C system parts (compressor, discharge line, suction line, evaporator, condenser, receiver/dryer, 
expansion valve, O-rings for joints) are designed for refrigerant R-134a. Do not exchange with R-12 
parts.  

z

Use a halogen gas leak detector designed for refrigerant R-134a.  

z

R-12 and R-134a refrigerant servicing equipment are not interchangeable. Use only a 
recovery/recycling/charging station that is U.L.-listed and is certified to meet the requirements of SAE 
J2210 to service R-134a air conditioning system.  

z

Always recover the refrigerant R-134a with an approved recovery/recycling/charging station before 
disconnecting any A/C fitting.
