3. CHARGE REFRIGERANT INTO REFRIGERATION
SYSTEM
If there is no leak after refrigerant leak check, charge the proper
amount of refrigerant into the refrigeration system.
CAUTION:

Do not run the engine when charging the system
through the high pressure side.

Do not open the low pressure hand valve when the
system is being charged with liquid refrigerant.
(a) Open the high pressure hand valve fully.
(b) Charge specified amount of refrigerant, then close the
high pressure hand valve.
HINT:
No bubbles in the sight glass indicates that the system is fully
charged.
(c) Partially charge the refrigeration system with refrigerant.
(1) Start engine and race engine at 1,500 rpm.
(2) Set fan speed selector to ºHIº.
(3) Set temperature control to ºMAX. COOLº.
(4) Set air inlet control to ºRECIRCº.
(5) Fully open doors (Sliding roof: closed).
(6) Open the low pressure hand valve.
CAUTION:
Do not open the high pressure hand valve.
(d) Charge refrigerant until bubbles disappear and check the
pressure on the gauge through the sight glass.

REMOVAL
1. DISCHARGE REFRIGERANT FROM REFRIGERATION
SYSTEM
HINT:
At the time of installation, first evacuate air from refrigeration
system.
Then, charge the system with the refrigerant and inspect for
leaks of the refrigerant.
Specified amount: 1,050 ± 50 g (37.04 ± 1.76 oz.)
2. DISCONNECT LIQUID AND SUCTION TUBES
Remove the bolt and slide the plate, then disconnect both
tubes.
Torque: 10 N´m (100 kgf´cm, 7 ft´lbf)
NOTICE:
Cap the open fittings immediately to keep moisture or dirt
out of the system.
HINT:
At the time of installation, lubricate 2 new O-rings with com-
pressor oil and install them to the tubes.
3. REMOVE REAR DOOR SCUFF PLATE RH
4. REMOVE REAR FLOOR MAT SUPPORT PLATE
5. REMOVE ROOF HEADLINING REAR TRIM
6. REMOVE QUARTER TRIM PANEL RH
7. REMOVE ROOF SIDE INNER UPPER GARNISH
(See page BO-97)
8. REMOVE NO. 1 COOLER AIR DUCT
(a) Remove the 3 roof headlining set clips.
(b) Remove the 5 clips and the No. 1 cooler air duct.

disconnect the connector.
HINT:
Tape the screwdriver tip before use.
2. INSPECT ROOM TEMPERATURE SENSOR
(See page DI-1330)
3. INSTALL ROOM TEMPERATURE SENSOR

COMPASS
PRE-CHECK
1. SELECTING COMPASS DISPLAY MODE
The mode select switch allows you to select a Display or Non-display mode of the compass.
The mode select is operated by the automatic glare-proof / non-glare proof switch on the inner mirror.
2. SETTING ZONE
Deviation between the magnetic north and ºactual northº differs depending on the terrestrial location, there-
fore, an adjustment in magnetism is required. Since the magnetic condition differs according to the area
where the vehicle will be used, it is necessary for each user to set the zone. (Refer to ºCompass Zone Mapº).
The zone setting can be changed using the mode select switch of the inner mirror.
3. PERFORMING CALIBRATION
Because each vehicle has its own magnetic field, calibration should be performed for each vehicle. This com-
pass function is used when storing the record of the vehicle's magnetic field.
4. WHEN COMPASS MAGNETIZED:
A compass could be magnetized during shipping by vessels or freight cars. Before delivery, therefore, make
sure to perform calibration and ensure that calibration can be done. If it cannot be done (cannot complete
in spite of driving round several times), it may be caused by magnetization. Demagnetize the vehicle using
a demagnetizer and perform calibration again.

6. SELECTING DISPLAY MODE
(a) Turn the ignition switch ON.
(b) Check that the LED on the inner mirror is lit (green).
(c) Check that the compass display indicates an azimuthal direction (N, NE, E, SE, S, SW, W, or NW) or
ºCº.
(d) Pressing the mode select switch on the inner mirror for 3 sec. or more erases the above mentioned
display and activates the Non-display mode.
HINT:

Immediately after pressing the mode select switch, the LED goes off activating the Non-glare-proof
mode. However, when the switch remains pressed, the LED is lit again after 3 sec. and the system
enters the automatic glare-proof mode.

Keep pressing the mode select switch for 3 sec. after selection of the compass display mode will acti-
vate the zone setting mode, showing a number (1-15) on the compass display.
