Precautions
A/C System CautionS7RS0B7210001
CAUTION!
• The air conditioning system of this vehicle uses refrigerant HFC-134a (R-134a).
None of refrigerant, compressor oil and component parts is interchangeable between two types of
A/C: one using refrigerant HFC-134a (R-134a) and the other using refrigerant CFC-12 (R-12).
Be sure to check which refrigerant is used be fore any service work including inspection and
maintenance. For identification between these two types, refer to “Refrigerant Type Identification”.
When replenishing or changing refrigerant and comp ressor 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.
• When servicing the compressor, keep dirt or foreign material away from getting on or into the compressor parts and system. Clean tools and a clean work area are important for proper service.
The compressor connection and the outside of the compressor should be cleaned before any “On
vehicle” repair or before removal of the compressor. The parts must be kept clean at all times and
any parts to be reassembled should be cleaned with trichloromethane, naphtha, kerosene or
equivalent solvent and dried with dry air. Use only lint free cloths to wipe parts.
• When compressor is removed from the vehicle for servicing, the oil remaining in the compressor
should be discarded and new refrigerant oil added to the compressor.
Minor repair procedures may be done on the vehicle without discharging the system. Major repair
procedures require that the system be discharged of refrigerant.

Precautions on Servicing A/C SystemS7RS0B7210002
WARNING!
Should refrigerant HFC-134a (R-134a) is exposed to your eye(s), consult a doctor immediately.
• Do not use your hand to rub affected eye(s). Instead, use fresh cold water to splash it over affected area to thus gradually raise its temperature above the freezing point.
• Obtain proper treatment as soon as possible from a doctor or eye specialist. Should liquid refrigerant HFC-134a (R-134a) is exposed to your skin, such affected part should be treated in the
same manner as when skin is frostbitten or frozen.

Handling Refrigerant HFC-134a (R-134a)
• Always wear goggles to protect your eyes.
• Avoid direct contact to liquid refrigerant.
• Do not heat refrigerant container higher than 40 °C (104 ° F).
• Do not discharge refrigerant into atmosphere.
• Do not expose bright metals to liquid refrigerant. Refrig erant combined with moisture is corrosive and tarnishes
surfaces of bright metals including chrome.

Refrigerant Line
• Never use heat for bending pipes. When bending a pipe , try to make its bending angle as smooth as possible.
• Keep internal parts of air conditioning free from moistu re and dirt. When disconnecting any line from system, install
a blind plug or cap to the fitting immediately.
• When connecting hoses and pipes, apply a few drops of compressor oil (refrigerant oil) to O-ring.
• When tightening or loosening a fitting, use two wrenches, one for turning and the other for support.
• When handling recovery and recycling equipment, be sure to follow the instruction manual for the equipment.
• Check local governmental regulations regarding working with refrigerator systems and its tooling.
• Route drain hose so that drained water does not make any contact to vehicle components.
• If pipes or hoses are replaced, replenish specified amount of compressor oil to compre ssor suction side referring to
“Replenishing Compressor Oil” in “Operation Procedure for Refrigerant Charge”.
Refrigerant Recovery
When discharging refrigerant out of A/C system, always recover it by using refrigerant recovery and recycling
equipment because discharging refrigerant HFC-134a (R-1 34a) into atmosphere would cause adverse effect to
environments.
NOTE
When handling recovery and recycling equipment, be sure to follow the instruction manual for the
equipment.

Refrigerant Charge
After performing compressor oil replenishment and evacuat ion, charge a proper amount of refrigerant to A/C system
referring to “Charge” in “Operation Procedure for Refrigerant Charge”.
