Precaution in Servicing Full-Time 4WD Vehicle

Precaution in Servicing Full-Time 4WD Vehicle

WARNING:

This full-time 4WD vehicle can not be converted to 2WD manually.

Failure to take proper precautions when servicing the full-time 4WD vehicle can cause front wheels drive rear wheels or vise-versa and vehicle accidents, drivetrain damage or personal injury.

- Never perform service work with the vehicle in any of the conditions shown below.
[A]: Testing with 2-wheel chassis dynamometer or speedometer tester (which tester roller is driven by vehicle wheels).
[B]: Driving front or rear wheels, which are jacked up.
[C]: Towing under the condition where either front or rear wheels can not rotate.






- When testing with 2-wheel brake tester, observe the following precautions:

- Shift transmission to N (Neutral) position.
- Shift transfer to N (Neutral) position, if transfer position is selectable.
- Run engine at specified idle speed.
- Rotate wheels (tires) by brake tester at vehicle speed below 5 km/h (3 mile/h).
Do not rotate wheels (tires) for more than 1 minute.

- When testing with 2-wheel speedometer tester (which wheels are driven by tester), observe the following precautions:

- Set rear wheels on tester roller and front wheels on free roller.
- Shift transmission to N (Neutral) position.
- Shift transfer to N (Neutral) position, if transfer position is selectable.
- Rotate wheels (tires) by tester at vehicle speed below 60 km/h (37 mile/h).
- Do not rotate wheels (tires) for more than 1 minute.
- Ensure that vehicle does not move using wire ropes or chains.

- When testing with 2-wheel chassis dynamometer, be sure to make the vehicle as rear wheel drive by removing front propeller shaft or as front wheel drive by removing rear propeller shaft, referring to Transfer Warning Transfer Warning:Motor-Shift Type (Transfer with Shift Actuator) or Transfer Warning Transfer Warning:Non-Shift Type (Transfer without Shift Actuator).
Note that speedometer does not display vehicle speed because rear wheel speed sensor signal is not output, if rear propeller shaft is removed.

- When testing with 4-wheel free chassis dynamometer or speedometer tester (which tester roller is driven by vehicle wheels), be sure to shift transfer to 4H-Lock position according to the step 2) in Transfer Warning Transfer Warning:Motor-Shift Type (Transfer with Shift Actuator).





- When using On-vehicle type wheel balancing equipment (1), observe the following precautions:

- Jack up all four wheels, off the ground completely and support vehicle with safety stands (2).
- Be careful not to be injured by the other wheels that rotate simultaneously with the wheel being balanced.






NOTE:

Improper towing can damage the tiers or the drive train components.

This vehicle should be towed under one of the following condition:

- With all wheels on a flatbed truck.
- With front or rear wheels lifted and on a dolly under the other wheels.
