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 vol
t
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 bracke
t
or the alternator mounting bracket) in the engine room o
f
the vehicle with the discharged battery.
Be sure that the ground connection is at least 500 mm (20
in) from the discharged battery.

Check level sensor operation
1. Remove the fuel tank unit.
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.
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.

ENGINE CONTROL (4JA1T(L) only)
Idling Speed Adjustment
1. Set the vehicle parking brake and chock the drive
wheels.
2. Place the transmission in neutral.
3. Start the engine and allow it to idle until the coolant
temperature reaches 70 - 80C (158 - 176F).


4. Disconnect the engine control cable from the control
lever.
5. Set a tachometer to the engine.
6. Check the engine idling speed.
If the engine idling speed is outside the specified
range, it must be adjusted.
Engine Idling Speed : 730  25 rpm


Idling Speed Adjustment
1. Loosen the idling set screw lock nut
on the injection
pump idling set bolt.
2. Adjust the idling speed to the specified range by
turning the idling set bolt
.
3. Lock the engine set nut

with the idling set bolt lock
nut.

Jump Starting Procedure
1. Set the vehicle parking brake.
If the vehicle is equipped with an automatic
transmission, place the selector level in the “PARK"
position.
If the vehicle is equipped with a manual
transmission, place the shift lever in the
“ NEUTRAL" position.
Turn “OFF" the ignition.
Turn “OFF" all lights and any other accessory
requiring electrical power.
2. Look at the built –in hydrometer.
If the indication area of the built –in hydrometer is
completely clear, do not try to jump start.
3.
Attach the end of one jumper cable to the positive
terminal of the booster battery.
Attach the other end of the same cable to the
positive terminal of the discharged battery.
Do not allow the vehicles to touch each other. This
will cause a ground connection, effectively
neutralizing the charging procedure.
Be sure that the booster battery has a 12 volt rating.
4. Attach one end of the remaining cable to the
negative terminal of the booster battery.
Attach the other end of the same cable to a solid
engine ground (such as the air conditioning
compressor bracket or the generator mounting
bracket) of the vehicle with the discharged battery.
The ground connection must be at least 450 mm
(18 in.) from the battery of the vehicle whose battery
is being charged.
WARNING: NEVER ATTACH THE END OF THE
JUMPER CABLE DIRECTLY TO THE NEGATIVE
TERMINAL OF THE DEAD BATTERY.
5. Start the engine of the vehicle with the good battery.
Make sure that all unnecessary electrical
accessories have been turned “OFF".
6. Start the engine of the vehicle with the dead battery.
7. To remove the jumper cables, follow the above directions in reverse order.
Be sure to first disconnect the negative cable from
the vehicle with the discharged battery.
