dust and water which can cause wear to steering rack
and pinion to produce noise as well as rust to result in
malfunction of steering system.
Even if boot tear is small, replace with new one.
Also, check each boot for dent. If there is a dent, keep
boot in most compressed state for some seconds to
correct dent.
Boots should be visually inspected for any damage, dent
and tear during every periodical inspection at specified
intervals and whenever vehicle is hoisted for any other
purpose.

Precautions
A/C System CautionS6RW0D7210001
CAUTION!
The A/C system of this vehicle uses HFC-134a (R-134a) refrigerant, specified compressor oil and
specified parts.
Do not use CFC-12 (R-12) refrigerant, R-12 exclusive use compressor oil and R-12 exclusive parts in
this A/C system, do not attempt to use R-12 servicing equipment. Otherwise, use of it will result in
leakage of refrigerant, damage or other faulty condition of A/C system and damage or other faulty
condition of servicing equipment.
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.

Precautions on Servicing A/C SystemS6RW0D7210002
WARNING!
Should refrigerant HFC-134a (R-134a) is exposed to your eye(s), consult a doctor immediately.
• Do not reuse 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. Refrigerant combined with moisture is corrosive and tarnishes
surfaces of bright metals including chrome.
• 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 moisture and dirt. When disconnecting any line from system, install
a blind plug or cap to the fitting immediately.
• 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.
• When connecting hoses and pipes, apply a few drops of compressor oil (refrigerant oil) to O-ring.
• Replace O-ring with new one once hoses, pipes and parts disconnected.
• When tightening or loosening a fitting, use two wrenches, one for turning and the other for support.
• 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 compressor suction side referring to
“Replenishing Compressor Oil” in “Operation Procedure for Refrigerant Charge”.

Trouble Diagnosis for Abnormal PressureS6RW0D7214002
NOTE
Normal pressure values on high side and low side in following table are measured when the ambient
temperature is 30 °C. As normal pressure values on high side and low side vary depending on the
ambient temperature, be sure to perform following steps first when diagnosing troubles.
1. Measure the ambient temperature and using that value, read the normal value from the graph given
in Step 10 of “A/C System Performance Inspection”.
2. Put that value in place of the normal pressure in following table.

Condition Possible cause Correction
Crossing point is higher
than acceptable range
(“E” area)Insufficient or excessive charge of refrigerant Check refrigerant pressure.
Dirty or bent A/C evaporator fins Clean or repair.
Air leakage from cooling (heater) unit or air duct Repair or replace.
Malfunctioning, switch over function of door in

Compressor malfunction Check compressor.
Crossing point is lower

Repair Instructions
Operation Procedure for Refrigerant ChargeS6RW0D7216001
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 place. It should never be stored in any place where
temperature is high, e.g. where exposed to direct sun 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.
