WARNING
■To avoid an accident
●Do not use the rear differential lock system except when wheel spinning
occurs in a ditch or on a slippery or ragged surface. Large steering effort
and careful cornering control will be required.

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 differential lock component parts.
●Do not drive over 5 mph (8 km/h) when the differential is locked.
●Do not keep driving with the rear differential lock switch on.
