SPECIAL HANDLING INSTRUMENTS FOR TOWING
Towing methodsRemarks
If a tow truck is used
Lifting method for 4 wheels – GoodFor 4WD models, the basic principle is that all
four wheels are to be raised before towing.
The shift lever should be set to 1st gear and
the parking brake should be applied.
Front wheels lifted – No goodThe vehicle must not be towed by placing only
its front wheels or only the rear wheels on a
rolling dolly, because to do so will result in
deterioration of the viscous coupling and result
in the viscous coupling causing the vehicle to
jump forward suddenly.
Front wheels lifted – No goodIf only the front wheels or only the rear wheels
are lifted for towing, the bumper will be damaged.
In addition, lifting of the rear wheels causes
the oil to flow forward, and may result in heat
damage to the rear bushing of the transfer, and
so should never be done.
Rear wheels lifted – No good
Towing by rope or cable – GoodThe front and rear wheels must rotate normally.
Both running and driving systems must function
normally.
The shift lever must be set to the neutral position
and the ignition key must be set to “ACC”.

ON-VEHICLE SERVICE
SPEEDOMETER CHECK
1. Adjust the pressure of the tyres to the specified level.
2. Set the vehicle onto a speedometer tester and use wheel
chocks to hold the rear wheels.
3. Pull the parking brake lever firmly.
4. To prevent the front wheel from moving from side to side,
attach tension bars to the tie-down hook, and secure
both ends to anchor plates.
5. To prevent the vehicles from starting, attach a chain or
wire to the rear towing hook, and secure the other end
of the chain or wire firmly to an unmovable body.
6. Check if the speedometer indication range is within the
standard values and if the pointer fluctuation is within
the limits.
Caution
Do not operate the clutch suddenly. Do not
increase/decrease speed rapidly while testing.
Standard values:
Vehicle speed km/hSpeedometer indication
allowable errors km/h
4037 – 45
8075 – 88
120113 – 132
160150 – 176
Limit: Pointer fluctuation
(at vehicle speeds of higher than 35 km/h) ±3 km/h
TACHOMETER CHECK
1. Insert a paper clip in the engine speed detection connector
from the harness side, and attach the engine
speedometer.
2. Compare the readings of the engine speedometer and
the tachometer at every engine speed, and check if the
variations are within the standard values.
Standard values:
700 r/min : ±100 r/min
3,000
*1 r/min : ±150 r/min
3,000*2 r/min : +225 to –100 r/min
5,000*1 r/min : ±250 r/min
5,000*2 r/min : +325 to –125 r/min
6,000*1 r/min : ±300 r/min
7,000*2 r/min : +400 to –100 r/min
8,000*3 r/min : +400 to 0 r/min
NOTE
*1: Tachometer measurable up to 8,000 r/min
*2: Tachometer measurable up to 9,000 r/min and one measurable up to 10,000 r/min
*3: Tachometer measureble up to 10,000 r/min
