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”.

General Description
Refrigerant Type IdentificationS7RS0B7211001
Whether the A/C system in the vehicle uses HFC-134a (R-134a) or CFC-12 (R-12) is indicated on label (1) on the
compressor. Also, it can be checked by th e shape of the service (charge) valve (2).

Operation Procedure for Refrigerant ChargeS7RS0B7216001
WARNING!
• Your eyes should not be exposed to refrigerant (liquid).Any liquid HFC-134a (R-134a) escaping by accident shows a temperature as low as approximately –
6 °C (21.2 ° F) below freezing point. Should liquid HFC-134a (R-134a) is exposed to your eyes, it may
cause a serious injury. To protect your eyes from such accident, it is necessary to always wear
goggles. Should it occur that HFC-134a (R-134a) is exposed to your eyes, consult a doctor
immediately.
– Do not use your hand to rub the affected eye(s). Instead, use fresh cold water to splash it over the affected area to gradually raise temperature of such area above freezing point.
– Obtain proper treatment as soon as possible from a doctor or eye specialist.
• Should the liquid refrigerant HFC-134a (R-134a) is exposed to your skin, the affected area should be treated in the same manner as when skin is frostbitten or frozen.
• Do not handle refrigerant near any place where welding or steam cleaning is performed.
• Refrigerant should be kept in a cold and dark pl ace. It should never be stored in any place where
temperature is high, e.g. where exposed to direct su n light, close to fire or inside vehicle (including
trunk room).
• Avoid breathing fume produced when HFC-134a (R-134a) is burned. Such fume may be hazardous to your health.

Charge
CAUTION!
• Because the sight glass is not used for this A/C system, do not perform an additional
charge to the A/C system. To charge the
proper amount of refrigerant, recover and
evacuate the A/C system first. And then,
charge the proper amount of refrigerant
into the A/C system.
• Always charge refrigerant through low pressure side of A/C system after the initial
charge is performed from the high
pressure side with the engine stopped.
• Never charge refrigerant through high pressure side of A/C system with engine
running.
• Do not charge refrigerant while compressor is hot.
• When installing tap valve to refrigerant container to make a hole there through,
carefully follow dire ctions given by
manufacturer.
• A pressure gauge should always be used before and during refrigerant charge.
• The refrigerant container should be emptied of refrigerant when discarding it.
• The refrigerant container should not be heated up to 40 °C (104 °F) or over.
• Refrigerant container should not be reversed in direction during refrigerant
charge. Reversing in direction causes
liquid refrigerant to enter compressor,
causing troubles, such as compression of
liquid refrigerant and the like.

NOTE
The air conditioning system contains HFC-
134a (R-134a).
Described here is a method to charge the air
conditioning system with refrigerant from the
refrigerant service container.
When charging refrigerant recovered by
using the refrigerant and recycling
equipment (when recycling refrigerant),
follow the procedure described in the
equipment manufacturer’s instruction
manual.

Charge proper amount of refrigerant accurately in
accordance with the following procedure.
Specified amount of refrigerant
370 ± 20 g (13.0 ± 0.7 oz)
The initial charge of the A/C system is performed
through the high pressure side with the engine stopped.
And next, this method must be followed by charging from
the low pressure side with the engine running.
1) Check if hoses are routed properly after evacuating the system.
2) Connect low charging hose (1) and high charging hose (2) of the manifold gauge set (3) in position.
Then, open refrigerant container valve (4) to purge
the charging line.
3) Open the high pressure side valve (5) and charge refrigerant to system.
4) After a while, open the low pressure side valve (6) and close the high pressure side valve.
WARNING!
Make sure that high pressure side valve is
closed securely.

5) Start engine and keep engine speed at 1500 r/min, and then operate A/C system.
6) Charge A/C system with refrigerant in vapor state. At this time, refrigerant container should be held
upright.
