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.
Switching differential locks on and off
The switches are located on the upper part of
the center console.

Switching differential locks on
! To avoid damage to the transfer case and
differential locks:
REngage the differential locks only at low
speed (walking speed, not more than
5 mph [8 km/h]).
RDo not engage the differential locks if the
driving wheels are spinning due to lack
of traction.
RDo not engage the differential locks on
paved roads.

Switching differential locks off
There are two different methods to disengage
differential locks:
RYou can switch the differential locks off in
reverse order (=, ;, :).
RTo switch off all differential locks at the
same time:
XPress switch :.
Yellow engagement indicator
lamps ? go out first. Red function
indicator lamps A go out when the
switching process has been carried
out in the differential.
To activate the ESP®, BAS, and ABS systems,
drive again for 3 seconds using a constant
driving style.
All messages in the multifunction display
disappear. The ESP® warning lamp d and
the ! indicator lamp in the instrument
cluster go out.
iIf red function indicator lamps A do not
go out when the differential locks are
disengaged, bring vehicle to a stop and
then continue driving. Changing the vehicle
load can help to disengage the differential
locks.
GWarning!
Always remember to disengage the
differential locks when returning to drive on
paved roads, see “A few words about
differentials and differential locks”.
Instrument cluster
Introduction
For a full view illustration of the instrument
cluster, see “Instrument cluster”
(Y page 26).
GWarning!
No messages will be displayed if either the
instrument cluster or the multifunction
display is inoperative.
As a result, you will not be able to see
information about your driving conditions,
such as
Rspeed
Routside temperature
Rwarning/indicator lamps
Rmalfunction/warning messages
Rfailure of any systems
Driving characteristics may be impaired.
If you must continue to drive, please do so
with added caution. Contact an authorized
Mercedes-Benz Center as soon as possible.
