WARNING
■ To avoid an accident
Failure to observe the following precautions may result in an accident.
● Do not use the rear differential lock system except when wheel spinning
occurs in a ditch or on a slippery or rugged surface. Large steering effort
and careful cornering control will be required.
● Do not lock the rear differential until the wheels have stopped spinning.
Otherwise, the vehicle may move in an unexpected direction when the dif-
ferential lock is engaged, resulting in an accident. This may also lead to
possible damage to rear differential lock component parts.
