Steering Wheel Play CheckS6RW0D6304021
• Check steering wheel for looseness or rattle by
moving it in its shaft direction and lateral direction.
If found defective, repair or replace.
• Check steering wheel for play, holding vehicle in
straight forward condition on the ground with engine
stopped.
If steering wheel play is not within specification,
inspect as follows and replace if found defective.
– Tie-rod end ball stud for wear (Ball stud should
move when more than 0.2 N⋅m (2 kg-cm, 0.44 lb-ft)
torque is applied.)
– Lower ball joint for wear
– Steering shaft joint for wear
– Steering pinion or rack gear for wear or breakage
– Each part for looseness

Steering Force CheckS6RW0D6304022
1) Place vehicle on level road and set steering wheel at
straight-ahead position.
2) Check if tire inflation pressure is as specified
referring to the tire placard.
3) Remove driver air bag (inflator) module referring to
“Driver Air Bag (Inflator) Module Removal and
Installation in Section 8B”.

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”.

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-134a) into atmosphere would cause adverse effect to
environments.
NOTE
• After recovering refrigerant from system,
the amount of removed compressor oil
must be measured for replenishing
compressor oil.
• When handling recovery and recycling
equipment, be sure to follow the
instruction manual for the equipment.

Replenishing Compressor Oil
It is necessary to replenish specified amount of
compressor oil to compressor from compressor suction
side hole (1) before evacuating and charging refrigerant.When charging refrigerant only
When charging refrigerant without replacing any
component, replenish the same amount of measured oil
when recovering refrigerant (if not measure, replenish 10
cm
3 (10 ml, 0.34 US.oz, 0.35 Imp.oz) oil).
When replacing compressor
CAUTION!
Be sure to use specified compressor oil or an
equivalent compressor oil.

Compressor oil is sealed in each new compressor by the
amount required for A/C system. Therefore, when using
a new compressor, drain the calculated amount of oil
from it.
“C” = “A” – “B”
“C”: Amount of oil to be drained
“A”: Amount of oil in a new compressor
“B”: Amount of oil in removed compressor
NOTE
Compressor assembly supplied from factory
