Precautions in Servicing 4WD Model
CAUTION:
Failure to take proper precautions when servicing a 4WD model can cause a vehicle accident, severe personal injury, or drivetrain damage.
- Never perform any of the following [A], [B] and [C] types of service work. If it is performed while 4WD-auto mode or 4WD-lock mode is selected, front wheels (or rear wheels) drive rear wheels (or front wheels) and vehicle accident, drivetrain damage and personal injury may result. Also, if it is performed while 2WD mode is selected, the coupling may be damaged because of the difference in revolution speed between front wheels and rear wheels.
- When testing the vehicle using a 2-wheel chassis dynamometer or speedometer tester, be sure to place the 4WD system in the 4WD-auto or 4WD-lock mode and place the front wheels on the dynamometer or speedometer tester and the rear wheels on a 2-wheel free roller. Alternatively, remove the propeller shaft to make only the front wheels work as drive wheels.
- When testing the vehicle using a 2-wheel brake tester, be sure to take the following precautions:
- Shift the transaxle to the N (Neutral) position.
- Place the 4WD system in the 2WD mode.
- Run the engine at a speed in the specified idle speed range.
- Drive the vehicle wheels with the brake tester at a vehicle speed below 5 km/h (3 mile/h).
- Do not drive the vehicle wheels with the brake tester for more than 1 minute.
- When using on-vehicle type wheel balancing equipment (1), observe the following precautions:
- Be sure to place the 4WD system in the 4WD-auto or 4WD-lock mode and raise and support the vehicle with safety stands (2) so that all four wheels are completely off the ground.
- Be sure to place the 4WD system in the 4WD-auto or 4WD-lock mode and raise and support the vehicle with safety stands (2) so that all four wheels are completely off the ground.
- Never select the 2WD mode, as this will damage the coupling in the drivetrain.
- Only tow the vehicle with all four wheels on a flatbed truck or with all four wheels on the ground.
