Differential locks
General notes
GWARNING
When the differentiall ocks are engaged,ABS,
4ETS, ESP
®and BAS are deactivated. As a
result, the wheelsc ould lock when braking
and the braking distance is increased.T here is
ar isk of an accident.
Disengage the differentiall ocks immediately
on firm surfaces with good grip.
!In order to avoid damage to the transfer
case, you must operate the vehicle on adyna-
mometer (1-axle dynamometer) only if:
Rthe axle not driven on is jacked up
or
Rthe corresponding propeller shaft is dis-
connected and the transfer case differen-
tial lock is engaged.
Otherwise,t he transfer case can be damaged.
Differential locks improve the traction of the
vehicle.
Your vehicle is equipped with adifferentiall ock
each for:
Rthe transfer case: this controls the balance
betweent he front and rear axles.
Rthe rear axle: this controls the balance
betweenthe wheelsont he rear axle.
Rthe front axle: this controls the balance
betweenthe wheelsont he front axle.
Information on differential gear system
and differential lock
When the vehicle drives around acurve, the
wheelsont he outsideoft he curve must cover a
greater distance. Therefore, the wheelst urn
more rapidly than on the inside. The differential,
ag ear system in the drive train, allows for dif-
fering rotational speedsa nd facilitates corner-
ing.
Off-road driving systems147
Driving and parking
Z
Page 150 of 286

The disadvantage ofadifferential is that the
wheels that have the least grip, get the most
drive. An example: awheel of adriven axle is on
as now-covered surface and therefor edoes not
have any traction. The differential sends most of
the drive force to this wheel because the force
takes the route of the lowest resistance. The
opposite wheel on this axle, however, which
stands on firm ground and could therefor eallow
propulsion, receives no driving power. 4ETS
compensates for this disadvantage. 4ETS pro-
vides good steerability by automatically braking
the spinnin gwheel. 4ETS provides the wheel on
the firm surface with more drive force, which in
turn provides propulsion.
ESP
®and 4ETS are traction systems that are
ideal for road driving and suitable for light off-
road driving. The LOW RANGEoff-road gear
also improves off-road capability.
More challenging off-road conditions require
additional measures such as lockingo ne or
more differential.
Your vehicle is equipped with three differential
locks:
Rfor the transfer case
Rfor the front axle
Rfor the rear axle
Each differential lock can be engaged with the
corresponding switch on the center console. If
the differential in the transfer case is locked, the
front and rear wheels rotateatt he same speed.
If the differential for the rear axle is locked, both
rear wheels rotateatt he same speed, regard-
less of their respective torque. Note, engaging
the differential lock greatly impairs the vehicle's
steerability.
Note, it is imperative to use the differential func-
tion when driving on firm road surfaces. Under
no circumstances should the differential be
locked when driving on firm road surfaces. Oth-
erwise, the vehicle may not be steerable and you
could lose control of the vehicle. Therefore, only
engage the differential lock when driving off-
road. You should only engage the differential
lock if activatin g4ETS and ESP
®driving systems
and LOW RANGE off-road gear prove to be
insufficient.

Important safety notes
GWARNING
When differential locks are engaged on afirm,
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 surfaces with good grip.
GWARNING
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
ar isk of an accident.

by increasing the speed. Reduce vehicle
speed and do not countersteer. Apply the
brake as necessary.
GWARNING
If you install aball coupling other than the one
delivered with the vehicle, the trailer tow hitch
and the rear axle may be overloaded. This
applies especially if the ball coupling in ques-
tion is longer or angled differently. This could
seriously impair the driving characteristics
and the trailer can come loose. There is arisk
of an accident.
Only install the ball coupling delivered with
the vehicle or aball coupling that is designed
to meet your trailer towing requirements. Do
not modify the ball coupling or the trailer tow
hitch.
GWARNING
If the ball coupling is not installed correctly or not secured with the bolt provided and the
correspondin gspring cotter, the trailer may
come loose. There is arisk of an accident.
Always install and secure the ball coupling as
described. Beforee very journey, ensure that
the ball coupling is secured with the bolt and
the correspondin gspring cotter.
!If you have atrailer tow hitc hretrofitted,
changes to the engin ecooling system may be
necessary, dependin gonthe vehicle type.
If you have atrailer tow hitc hretrofitted,
observe the anchorage point sonthe chassis
frame.
The installation of atrailer tow hitc hisonly per-
missible if atowing weight is specified in your
vehicle documents. If this is not the case, then
the vehicle is not approved for the towing of a
trailer.
For more information ,please contact aqualified
specialist workshop.
Please observe the manufacturer's operating
instructions for the trailer coupling if adetach-
able trailer coupling is used.
Exceeding the maximum permissible nose-
weight of the trailer drawbar on the ball coupling may cause damage. Damage may be caused to the following:
RTowing vehicle
RTrailer
RBall coupling
RTrailer tow hitch
The vehicle/trailer combination could become
unstable.
If the noseweight used is lower than the mini-
mum permissible noseweight ,the vehicle/
trailer combination could also become unstable.
To avoid hazardous situations:
Rmake sure to checkt he noseweight before
each journey
Ruse adrawbar noseweight as close as possi-
ble to the maximum noseweight
Rdo not exceed the maximum permissible
noseweight
Rthe noseweight must not be lower than the
minimum permissible noseweight
Make sure that the following values are not
exceeded:
Rthe permissible trailer drawbar noseweight
Rthe permissible trailer load
Rthe permissible rear axle load of the towing
vehicle
Rthe maximum permissible gross vehicle
weight of both the towing vehicle and the
trailer
When backin gupthe vehicle towards the trailer,
make sure ther eisnobody between the trailer
and the vehicle.
The applicable permissible values, which must
not be ex
ceeded, can be found:
Rin your vehicle documents
Ron the type plate for the trailer
Ron the vehicle identification plate
If the values differ, the lowest value applies.
You will find the values approved by the manu-
facturer on the vehicle identification plates and
those for the towing vehicle under "Technical
data" (
Ypage 284).
When backin gupthe vehicle towards the trailer,
make sure ther eisnobody between the trailer
and the vehicle.
Couple and uncouple the trailer carefully. If you
do not couple the trailer to the towing vehicle
correctly, the trailer could become detached.
