switches in sequential order (center, rear,
front) (Y page 94). When the transfer case
(center) differential is locked, half of the
engine’s power is automatically distributed to
the front wheels and half to the rear wheels.
When the rear differential is locked, power
going to the rear wheels is equally distributed,
so that both rear wheels turn at the same
speed and torque. Please be aware that
engaging the differential locks will
significantly reduce the steering ability of the
vehicle.
For your safety and the safety of others and
to prevent damage to the vehicle, the
differential locks must not be engaged when
driving on paved roads. It is important to
understand that during on-road/paved
driving, differentials are absolutely necessary
for providing the essential control and
steering ability of the vehicle. The differential
locks, therefore, must not be engaged when
driving on paved roads and should only be
used to the extent necessary to negotiate off-
road conditions which cannot be handled by
the systems (the 4-ETS, the ESP
®
, and the
manual switch position “LOW” of transfer
case) this vehicle comes equipped with.
