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.
