• Never allow workers other than the responsible person to touch the vehicle containing high voltage
parts. To keep others from touching the high voltage parts, these parts must be covered with an insu-
lating sheet except when using them. Refer to
GI-34, "High Voltage Precautions"
CAUTION:
Never bring the vehicle into the READY status with the service plug removed unless otherwise
instructed in the Instruction. A malfunction may occur if this is not observed.
REMOVAL
WARNING:
Disconnect high voltage circuit. Refer to
GI-33, "How to Disconnect High Voltage"
.
1. Check voltage in high voltage circuit. (Check that condenser are discharged.)
a. Lift up the vehicle, and then remove Li-ion battery under covers. Refer to
b. Disconnect high voltage connector from front side of Li-ion battery. Refer to
.
c.
Measure voltage between high voltage harness terminals.
DANGER:
Touching high voltage components without using the appropriate protective equipment will
cause electrocution.
CAUTION:
For voltage measurements, use a tester which can measure to 500 V or higher.
2. Use the refrigerant recovery equipment (for HFC134a) and recover the refrigerant.
.
3. Remove radiator upper grille. Refer to
DLK-165, "RADIATOR UPPER GRILLE : Removal and Installa-
4. Remove bolt (A) and disconnect low-pressure flexible hose from electric compressor.
WARNING:
To prevent electric shock hazards, be sure to wear protective gear.

lating tape around disconnected high voltage connector
terminals.
7. Disconnect normal charge port connector (1) inside motor room.
WARNING:
•
To prevent electric shock hazards, be sure to wear
protective gear.
• To prevent electric shock hazards, immediately wrap insu-
lating tape around disconnected high voltage connector
terminals.
8. Move the water hose to a position where it will not interfere with work.
9. Remove front under cover. Refer to
EXT-23, "FRONT UNDER COVER : Removal and Installation"
.
10. Remove front wheel and tire (RH). Refer to

16. Remove electric compressor (1) from the vehicle.
WARNING:

protective gear.
INSTALLATION
Note the following items, and then install in the reverse order of removal.
WARNING:
To prevent electric shock hazards, be sure to wear protective gear.
CAUTION:
• Be sure to reinstall high voltage harness clips in their original positions. If a clip is damaged, replace
it with a new clip before installing.
• Before installing the new compressor, adjust the compressor oil level. Refer to
Adjusting Procedure for Compressor Replacement"
• To prevent degradation in insulation performance, use special electric compressor oil as the com-
pressor oil.
• In order to prevent conventional PAG oil from becoming mixed in, never reuse recovered compres-
sor oil and instead always use new oil. The use of oil including the conventional PAG oil may
degrade the performance of insulation.
• To prevent performance degradation, never use a fluorescent agent in order to detect refrigerant
leakage. Also be careful that a fluorescent agent never enter the oil.
• To prevent leakage of refrigerant, replace the O-ring with a new one. Apply a coat of compressor oil
to the O-ring prior to installation.
• Perform a check for refrigerant leakage when charging with refrigerant. Refer to
.
• Set the vehicle to READY and operate the air-conditioner for at lease 1 minute with the vehicle
parked to perform a break-in.
• If the compressor stay was replaced, first check that there is no
dust or dirt on the surface of the compressor stay, then apply the
new high voltage warning label at position (A), with the direction
indicated by the arrow facing up.
