After unlocking the rear differential

To check that the indicator goes off, turn the engine switch to the ON posi-
tion, but do not start the engine.
CAUTION
To avoid an accident
n
l 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.
l 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 differential lock component parts.
Do not drive over 5 mph (8 km/h) when the differential is locked.
l
l Do not keep driving with the RR DIFF LOCK switch on.
