Engaging the differential lock on 4x4

Engage the differential lock just before
reaching the slippery surface and disengage
it once you have past the slippery surface.
None of the wheels may be spinning before
the differential lock is engaged!
1 Make sure none of the wheels are spin-
ning
2 Depress the clutch pedal
3 Engage the differential lock between the
rear wheels.
The control lamp on the instrument panel
will flash.
Note! The differential lock is not engaged
until the warning lamp on the instrument
panel flashes. The differential lock is en-
gaged as long as the warning lamp is
flashing, even if the switch is turned off.
4 Move the front-wheel drive switch to its
bottom position.
The control lamp on the instrument panel
will come on.
Warning!
Drive carefully once the dif-
ferential lock is engaged. Never turn
corners on firm ground with the differ-
ential lock engaged.
