WARNING
When the transfer case is in the neutral posi-
tion, power transmission to the driven wheels
is interrupted. As a result, the vehicle could
roll away. There is a risk of an accident.
Secure the vehicle with the parking brake, and
on uphill or downhill gradients, also secure it
with a device such as a wheel chock.

Differential locks
General notes
G
WARNING
When the differential locks are engaged, ABS,
4ETS, ESP ® and BAS are deactivated. 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 surfaces with good grip.
! In order to avoid damage to the transfer
case, you must operate the vehicle on a
dynamometer (1-axle dynamometer) only
if:
the axle not driven on is jacked up
R
or
the corresponding propeller shaft is dis-
R
connected and the transfer case differ-
ential lock is engaged.
Otherwise, the transfer case can be dam-
aged.
Differential locks improve the traction of the
vehicle.
Your vehicle is equipped with a differential
lock each for:
the transfer case: this controls the balance
R
between the front and rear axles.
the rear axle: this controls the balance
R
between the wheels on the rear axle.
the front axle: this controls the balance
R
between the wheels on the front axle.
Information on differential gear system
and differential lock
When the vehicle drives around a curve, the
wheels on the outside of the curve must cover
a greater distance. Therefore, the wheels turn
more rapidly than on the inside. The differen-
tial, a gear system in the drive train, allows for
differing rotational speeds and facilitates cor-
nering.
