"Lock rear differential
To lock the rear differential, push and turn the switch clockwise
until it clicks.
Be sure to stop the wheels before locking the differential.
For easy locking, turn the lock switch and gently depress the
accelerator pedal.
The indicator light will blink when the switch is turned on. Wait a
few seconds for the system to complete operation. After the
differential is locked, the light will stop blinking and remain on.
The anti−lock brake system does not operate when the rear
differential is locked. It is normal operation for the "ABS" warning
light to be on at this time.
STARTING AND DRIVING
CAUTION
D Do not lock the differential until the wheels have stopped
spinning. Otherwise, the vehicle may move in an
unexpected direction when the differential lock is engaged,
resulting in an accident. This may also lead to possible
damage to differential lock component parts.
D Do not drive over 8 km/h (5 mph) when the differential is
locked.
To unlock the differential, turn the switch fully
counterclockwise.
Unlock the differential as soon as the vehicle moves out.
For easy unlocking, slightly turn the steering wheel in either
direction while the vehicle is moving.
When the differential lock is disengaged, the indicator light will go
out.
The differential will also unlock if you shift the four−wheel drive
control lever to "H". Never forget to turn off the switch after using
this feature.
To check the indicator bulb, turn the ignition key to the "ON"
position, but do not start the engine.
CAUTION
Do not keep driving with the differential lock switch on.
