– while moving at a turn with the differential lock switched on,
the motor vehicle lacks turnability and has a tendency to drift to
the outer turning circle, especially on roads with low coefficient
of adhesion;
– switch on the lock only with the engine on, after the vehicle
stops. Do not try to switch on the lock while the wheels are slip-
ping, as this will lead to shock load and breakdown of parts;
– switch on the lock only if engaging the front axle is not enough
to overcome the hindrance, and only after the front axle is engaged;
– do not switch off the lock while moving at a turn.
After the lock switching off signal is received, the locking clutch
may remain switched on for some time. The clutch will switch off
after gas-pedal release, for instance, during gear shift. After the
hindrance is overcome, and the differential lock is switched off
(either manually or automatically) make sure that the clutch has
unblocked the differential (while moving at turns, neither wheels
slippage nor knocks in the transmission are detected, and the
controllability of the motor vehicle does not differ from usual).
The switching on of the differential lock does not necessarily
increase the off-road capability of the motor vehicle. For instance,
while driving on soft (waterlogged) ground, the switched on dif
-
ferential lock can lead to turf disruption, and the “burying” of the
wheels. Switching on the lock is especially efficient at diagonal
lifting of the vehicle’s wheels or at huge difference in the adhesion
of the wheels on the right and on the left.
23. To prevent excessive loads on the axle differential, avoid
long-term slipping of one of the wheels.
24. When operating the motor vehicle in the cold season (ambi-
ent temperature of 0 °С and lower) it is recommended to apply a
cold weather radiator cowl cover.
To prevent freezing through of the pipe crankcase ventilation
system, at ambient temperature below (-15 °С), it is necessary to
disconnect the resonator-type hose from the air filter, turn the filter
tightly counter-clockwise (the inlet air filter is directed backwards
and downwards).
