LUBRICANT

Lubricant Adjusting Procedure for Components Replacement Except Compressor

After replacing any of the following major components, add the correct amount of lubricant to the system.
Amount of lubricant to be added

●

*1:

If compressor is replaced, addition of lubricant is included in the flow chart.

●

*2:

If refrigerant leak is small, no addition of lubricant is needed.

Lubricant Adjusting Procedure for Compressor Replacement

1.

Before connecting recovery/recycling equipment to vehicle, check recovery/recycling equipment gauges.
No refrigerant pressure should be displayed, recover refrigerant from equipment lines and then check
refrigerant purity.

2.

Confirm refrigerant purity in supply tank using recovery/recycling equipment and refrigerant identifier.

3.

Confirm refrigerant purity in vehicle A/C system using recovery/recycling equipment and refrigerant identi-
fier.

4.

Discharge refrigerant into the refrigerant recovery/recycling equipment. Measure lubricant discharged into
the recovery/recycling equipment.

5.

Drain the lubricant from the old (removed) compressor into a graduated container and record the amount
of lubricant drained.

6.

Drain the lubricant from the new compressor into a separate, clean container.

7.

Measure an amount of new lubricant installed equal to amount drained from old compressor. Add this
lubricant to new compressor through the suction port opening.

8.

 Measure an amount of new lubricant equal to the amount recovered during discharging. Add this lubri-
cant to new compressor through the suction port opening.

9.

If the liquid tank also needs to be replaced, add an additional 5 m  (0.2 US fl oz, 0.2 Imp fl oz) of lubricant
at this time.

Control Operation

EJS00200

FAN CONTROL KNOB

This knob turns the fan ON and OFF, and controls fan speed.

MODE CONTROL KNOB

This knob controls the direction of air flow through the front discharge outlets. The air conditioner compressor
turns on when the switch is turned to the defrost 

 or foot/defrost 

 position.  It will remain on until the key

is turned off or the fan switch is turned off (it will remain off only while the fan is off).

TEMPERATURE CONTROL KNOB

This knob allows adjustment of the outlet air temperature.

RECIRCULATION (REC) SWITCH

OFF position: Outside air is drawn into the passenger compartment.
ON position: Interior air is recirculated inside the vehicle. The indicator lamp will also light.

AIR CONDITIONER SWITCH

The air conditioner switch controls the A/C system. When the switch is depressed with the fan ON, the A/C
relay is activated by the ECM allowing compressor operation. The indicator lamp will also light.
The air conditioner cooling function operates only when the engine is running and ambient air temper-
ature is above 2

°C (35°F).

REAR WINDOW DEFOGGER SWITCH (IF EQUIPPED)

OFF position: Rear window defogger is not operating.
ON position: Rear window defogger is operating.
