Transfer Case: Service Precautions

SERVICE PRECAUTIONS

TOWING

- The vehicle must be towed by a tow truck with all four wheels raised. If a vehicle is towed with only the front or rear wheels are raised, the drive system components may be damaged or the vehicle may jump out of a tow truck (cart).

- Even if the drive mode selector is switched to "FWD," the vehicle cannot be towed with only the front or rear wheels raised. The vehicle must be towed by a tow truck with all four wheels raised.

WHEEL AND TIRE

Normally, all four tires must be same in size, in type, and in brand, except for when a spare tire is temporarily used. If a wheel or tire with incorrect size is installed or tire pressure is excessively out of the specified value, the electronic control AWD system will not operate correctly. In addition, drive system components may be damaged.

DRIVING ON SANDY OR SLUSHY ROAD

As the vehicle is intended for on-road use, long-time driving on a sandy or slushy road must be avoided. When the vehicle is driven on a sandy or slushy road for a long time, the fail-safe function of the electronic control AWD system tends to enter the protective control mode which switches the control from AWD to FWD gradually in order to protect the drive system, and the indicators ("AWD" and "LOCK") tends to illuminate.

SPEED MEASUREMENT

When using the chassis dynamometer to measure the speed, always measure it under synchronized condition between front wheels' speed and rear wheels' speed. If the speed is measured with front wheels or rear wheels fixed, or with speed difference between front wheels and rear wheels, drive system components may be damaged.
