Checking of A/T PositionACS002RS
1. Place selector lever in “P” position, and turn ignition switch ON (Do not start engine).
2. Make sure selector lever can be shifted to other than “P” position when brake pedal is depressed. Also
make sure selector lever can be shifted from “P” position only when brake pedal is depressed.
3. Move the selector lever and check for excessive effort, sticking, noise or rattle.
4. Confirm the selector lever stops at each position with the feel of engagement when it is moved through all
the positions. Check whether or not the actual position the selector lever is in matches the position shown
by the shift position indicator and the transmission body.
5. The method of operating the lever to individual positions cor-
rectly should be as shown in the figure.
6. When selector button is pressed in “P”, “R”, or “N” position with-
out applying forward/backward force to selector lever, check but-
ton operation for sticking.
7. Confirm the back-up lamps illuminate only when lever is placed
in the “R” position. Confirm the back-up lamps does not illumi-
nate when selector lever is pushed against “R” position in the
“P” or “N” position.
8. Confirm the engine can only be started with the selector lever in
the “P” and “N” positions.
9. Make sure transmission is locked completely in “P” position.
10. When selector lever is set to manual shift gate, make sure manual mode is displayed on combination
meter.
Shift selector lever to “+” and “-” sides, and make sure set shift position changes.

PRECAUTIONS
Revision: 2004 November 2004 FX35/FX45
VACUUM PUMP
The lubricant contained inside the vacuum pump is not compatible
with the specified lubricant for HFC-134a (R-134a) A/C systems.
The vent side of the vacuum pump is exposed to atmospheric pres-
sure. So the vacuum pump lubricant may migrate out of the pump
into the service hose. This is possible when the pump is switched off
after evacuation (vacuuming) and hose is connected to it.
To prevent this migration, use a manual valve placed near the hose-
to-pump connection, as follows.
Usually vacuum pumps have a manual isolator valve as part of
the pump. Close this valve to isolate the service hose from the
pump.
For pumps without an isolator, use a hose equipped with a man-
ual shut-off valve near the pump end. Close the valve to isolate
the hose from the pump.
If the hose has an automatic shut-off valve, disconnect the hose
from the pump. As long as the hose is connected, the valve is
open and lubricating oil may migrate.
Some one-way valves open when vacuum is applied and close
under a no vacuum condition. Such valves may restrict the pump′s
ability to pull a deep vacuum and are not recommended.
MANIFOLD GAUGE SET
Be certain that the gauge face indicates HFC-134a or R-134a. Be
sure the gauge set has 1/2″-16 ACME threaded connections for ser-
vice hoses. Confirm the set has been used only with refrigerant
HFC-134a (R-134a) and specified lubricants.
SERVICE HOSES
Be certain that the service hoses display the markings described
(colored hose with black stripe). All hoses must include positive shut
-off devices (either manual or automatic) near the end of the hoses
opposite the manifold gauge.

LUBRICANT ADJUSTING PROCEDURE FOR COMPRESSOR REPLACEMENT
1. Before connecting recovery/recycling recharging equipment to vehicle, check recovery/recycling recharg-
ing equipment gauges. No refrigerant pressure should be displayed. If NG, recover refrigerant from equip-
ment lines.
2. Connect recovery/recycling recharging equipment to vehicle. Confirm refrigerant purity in supply tank
using recovery/recycling recharging equipment and refrigerant identifier. If NG, refer to AT C - 5 , "
CONTAM-
INATED REFRIGERANT" .
3. Confirm refrigerant purity in vehicle A/C system using recovery/recycling recharging equipment and refrig-
erant identifier. If NG, refer to AT C - 5 , "
CONTAMINATED REFRIGERANT" .
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 recover 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 lubricant
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 lubri-
cant at this time.
Do not add this 5 m (0.2 US fl oz., 0.2 Imp fl oz.) of lubricant if only replacing the compressor.

DISPLAY SCREEN
Displays the operational status of the system.
AUTO SWITCH
The compressor, intake doors, air mix doors, outlet doors and blower speed are automatically controlled
so that the in-vehicle temperature will reach, and be maintained at the set temperature selected by the
operator.
When pressing AUTO switch, air inlet, air outlet, fan speed, and discharge air temperature are automati-
cally controlled.
TEMPERATURE SWITCH (POTENTIO TEMPERATURE CONTROL) (DRIVER SIDE)
Increases or decreases the set temperature.
TEMPERATURE SWITCH (POTENTIO TEMPERATURE CONTROL) (PASSENGER SIDE)
Increases or decreases the set temperature.
When the temperature switch is pressed, the dual switch indicator will automatically illuminate.
RECIRCULATION (REC) SWITCH
When REC switch is ON, REC switch indicator turns ON, and air inlet is fixed to REC.
When REC switch is ON and is pressed for approximately 1.5 seconds or longer, REC and FRE switch
indicators blink twice. Then, automatic control mode is entered. Inlet status is displayed even during auto-
matically controlled.
When FRE switch is turned ON, or when compressor is turned from ON to OFF, REC switch is automati-
cally turned OFF (fixed to FRE mode). REC mode can be re-entered by pressing REC switch again.
REC switch is not operated when DEF switch is turned ON, or at the D/F position.
FRESH (FRE) SWITCH
When FRE switch is ON, FRE switch indicator turns ON, and air inlet is fixed to FRE.
When FRE switch is ON and is pressed for approximately 1.5 seconds or longer, REC and FRE switch
indicators blink twice. Then, automatic control mode is entered. Inlet status is displayed even during auto-
matically controlled.
When REC switch is turned ON, FRE switch is automatically turned OFF (fixed to REC mode). FRE mode
can be re-entered by pressing FRE switch again.
DEFROSTER (DEF) SWITCH
Positions the air outlet doors to the defrost position. Also positions the intake doors to the fresh air position.
REAR WINDOW DEFOGGER SWITCH
When illumination is ON, rear window is defogged.
OFF SWITCH
The compressor and blower are OFF, the intake doors are set to the fresh air position, and the air outlet doors
are set to the foot (75% foot and 25% defrost) position.
A/C SWITCH
The compressor is ON or OFF.
(Pressing the A/C switch when the AUTO switch is ON will turn off the A/C switch and compressor.)
MODE SWITCH
Controls the air discharge outlets.
FAN SWITCH
Manually control the blower speed. Seven speeds are available for manual control (as shown on the display
screen).
DUAL SWITCH (WITH LEFT AND RIGHT VENTILATION TEMPERATURE SEPARATELY CON-
TROL SYSTEM)
When the DUAL switch indicator is not illuminated and the DUAL switch is pressed, the driver-side setting
temperature and passenger-side setting temperature can each be set independently.
When the DUAL switch indicator is illuminated and the DUAL switch is pressed, the driver-side setting
temperature are applied to both sides.
