Bleed air from clutch operating cylinder according to the
following procedure.
Carefully monitor fluid level at master cylinder during bleeding
operation.


1. Set the parking brake.
2. Top up reservoir with recommended brake fluid.



3. Connect a transparent vinyl tube to air bleeder valve.
4. Fully depress clutch pedal several times.


RUW 57CSH000201

5. W ith clutch pedal depressed, open bleeder valve to release
air.
6. Close bleeder valve.
7. Repeat steps 5 through 6 above until brake fluid flows from air bleeder valve without air bubbles.

7D1-48 TRANSFER CONTROL SYSTEM
Restriction on operation (4JA1-T)
The 4H, neutral and 4L shifting mechanism has no synchronization function. Therefore, if relative rotations in the
mechanism become excessive, shifting exerts adverse influence on the internal mechanism of the transfer. To
avoid such a trouble, vehicle condition is detected to restrict the operation (vehicle speed, and TM position).
Requirement to restrict the speed: Vehicle should be in stop.
Requirements for permission of restriction on engine speed: Engine speed should be decreased.
The engine speed of 3000rpm or below is advisable.
Requirements for permission of restriction on T/M position restriction:
should be at the neutral.

These requirements for permission should be all met before the switch is operated. If the requirements are met
after operation, operation is not automatically effected but re-operation is required after permission is given.
Note: Don’t’ accelerate engine speed a the time of this operation.

Step 3-3:
Stop the vehicle. (Close the accelerator and decrease the engine speed to below L4: 3000rpm, V6: 2000rpm.)
(In case of AT): Set the transmission select lever to the N position.
(In case of MT): Set the transmission lever to the neutral position. (Stepping on the clutch is recommended.) Push the 4L button.
If shifting operation is not completed (the lamp flashes at 2Hz), perform step 3-1.

4. Shifting from 4L to 4H
4-1 When 4L indicator continues flashing at 2Hz
W hen shifting from 4L to 4H, the 4L indicator continues flashing at 2Hz until the shifting in the transfer case is
completed. Phases of engaged splines may deviate and the operation may not be completed in some cases.
Shifting is completed by correcting the deviation of the splines.

Step 4-1: (same as step 3-1)
(In case of AT): Set the transmission select lever to the D position.
(In case of MT): Shift the transmission lever to a position allowing running and engage the clutch gently.

4-2 When the indicator continues flashing at 2Hz for 10 seconds and then keeps on at 4L again (AT
vehicle)
This condition occurs when torsional torque has been generated between the transmission and the road
surface (use of the parking position on a slope). Resistance against the separation of the driving force cannot
be completed by the waiting mechanism of the transfer.
Shifting is also possible by using the brake at the neutral position of the transmission

Step 4-2: (Same procedure as the step 3-2)
Set the transmission select lever to the N position.
(Leaving the brake lever and stepping on it again is recommended.)

4-3 When the 4L indicator flashes at 4Hz
Shifting from 4L to 4H is restricted.
W hen the vehicle is running, the transmission lever is at the running range, and the engine speed is high, the
transfer 4L cannot be shifted to 4H.

8A-20 ELECTRICAL-BODY AND CHASSIS
Caution:
Never push or tow the vehicle in an attempt to start it.
Extensive damage to the emission system and other
vehicle parts will result.
(Only catalytic converter vehicle)
Treat both the discharged battery and the booster battery
with great care when using jumper cables.
Carefully follow the procedure outlined below.
Always be aware of the dangers of sparking.
Failure to follow the following procedure can result in:
a. Serious personal injury, specially to your eyes.
b. Extensive property damage from a battery explosion, battery acid discharge, or electrical file.
c. Extensive damage to the electronic components o
f
both vehicles.
Do not use a 24 volt booster battery.
Serious damage to the vehicle's electrical system and
electronic components will result.

Jump Starting Procedure
1. Set the parking brake on both vehicles.
2. If one or both vehicles is equipped with a manual transmission, place the gear shift in the "NEUTRAL"
position.
3. Turn off the ignition on both vehicles.
4. Turn off all vehicle lights and accessories.
5 Be sure that the two vehicles are not touching.

Attach the end of one jumper cable to the booster battery
positive terminal.
6
Attach the other end of the same cable to the discharged
battery positive terminal.
7. Once again, check that the booster battery has a 12 volt rating.
8.
Attach one end of the remaining booster cable to the
booster battery negative terminal.
9.
Attach the other end of the booster cable to a solid ground
(such as the air conditioner compressor mounting bracket
or the alternator mounting bracket) in the engine room o
f
the vehicle with the discharged battery.
10.Be sure that the ground connection is at least 500 mm (20 in) from the discharged battery.

2. Apply battery voltage between terminal (B) and (C) through a 1.12 watt bulb. Check that the bulb lights.
Note:
It will take a short time for the bulb light.
3. Submerge the sensor in fuel. Check that the bulb goes out.
If operation is not correct, replace the fuel tank unit.

BRAKE SYSTEM WARNING LIGHT
The brake system warning light comes on while the parking
brake is set and the engine run position.

RTW 48AMH000101


Note:
The parking brake indicator light circuit is designed to
prevent driving of the vehicle with the parking brake on.
It does not indicate the condition of the parking brake
system.

The parking brake switch is in parallel with the brake fluid
switch.


The brake system warning light also comes on when reservoir
brake fluid level falls below the specified limit with the parking
brake released and the engine run position.
