R a central differential lock for the transfer
case,
R
a differential lock for the front axle and
R
a differential lock for the rear axle.
Each differential lock can be engaged with the
respective switch on the center console. If
the transfer case differential is disabled, the
front and rear wheels turn at the same speed.
If the differential for the rear axle is locked,
both rear wheels turn at the same speed,
regardless of their individual torques. Please
note that activating the differential locks
severely restricts the vehicle's steerability.
Please note that the functions of the
differential are absolutely necessary for
driving on paved roads. The differential locks
must never be engaged when driving on
paved roads. Otherwise, the vehicle may not
be steerable and you could lose control of the
vehicle. The differential locks must therefore
only be engaged when driving off-road. You
may only engage the differential locks if the
functions of the 4ETS and ESP
® driving
systems and the LOW RANGE off-road gear
are insufficient.
i The differential locks are only available in
the LOW RANGE off-road gear.
Activating the differential lock
Important safety notes
G WARNING
When differential locks are engaged on a firm,
high-grip surface, the vehicle's steerability is
greatly impaired. In particular, engaging the
differential locks when cornering could lead
to you losing control of the vehicle. There is a
risk of an accident.
Disengage the differential locks immediately
on firm, high-grip surfaces.
G WARNING
ABS, 4ETS, ESP ® and BAS are deactivated
while the differential locks are engaged. As a
result, the wheels could lock when braking
and the braking distance is increased. There
is a risk of an accident.
Disengage the differential locks immediately
on firm, high-grip surfaces.
! Only activate the differential locks when:
R
you are driving at walking pace.
R
the driven wheels are not spinning.
R
you are not driving on a firm road surface.
