WARNING
If you do not wait for the transfer case gear
change process to complete, the transfer
case could remain in the neutral position. The power transmission to the driven wheels is
then interrupted. There is a danger of the
vehicle rolling away unintentionally. There is a
risk of an accident.
Wait until the transfer case shift process is
completed.
Do not switch off the engine while changing
gear and do not shift the automatic transmis-
sion to another gear. HIGH

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.

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:
R the axle not driven on is jacked up
or
R the corresponding propeller shaft is dis-
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. 188
Off-road driving systemsDriving and parking

Your vehicle is equipped with a differential
lock each for:
R the transfer case: this controls the balance
between the front and rear axles.
R the rear axle: this controls the balance
between the wheels on the rear axle.
R the front axle: this controls the balance
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.
The disadvantage of a differential is that the
wheels that have the least grip, get the most
drive. An example: a wheel of a driven axle is
on a snow-covered surface and therefore
does not have any traction. The differential
sends most of the drive force to this wheel
because the force takes the route of the low-
est resistance. The opposite wheel on this
axle, however, which stands on firm ground
and could therefore allow propulsion,
receives no driving power. 4ETS compen-
sates for this disadvantage. 4ETS provides
good steerability by automatically braking the spinning wheel. 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 locking one or
more differential. Your vehicle is equipped
with three differential locks: 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 corresponding switch on the center console.
If the differential in the transfer case is
locked, the front and rear wheels rotate at the
same speed. If the differential for the rear axle
is locked, both rear wheels rotate at the same speed, regardless of their respective torque.
Note, engaging the differential lock greatly
impairs the vehicle's steerability.
Note, it is imperative to use the differential
function when driving on firm road surfaces.
Under no circumstances should the differen-
tial be locked when driving on firm road sur-
faces. Otherwise, the vehicle may not be
steerable and you could lose control of the
vehicle. Therefore, only engage the differen-
tial lock when driving off-road. You should
only engage the differential lock if activating
4ETS and ESP ®
driving systems and LOW
RANGE off-road gear prove to be insufficient.
Engaging the differential locks 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 surfaces with good grip. 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.

Notes on towing a trailer
Important safety notes G
WARNING
If you rest your foot on the brake pedal while
driving, the braking system can overheat. This increases the stopping distance and can even
cause the braking system to fail. There is a
risk of an accident.
Never use the brake pedal as a footrest. Never
depress the brake pedal and the accelerator
pedal at the same time. G
WARNING
When the vehicle/trailer combination begins
to lurch, you could lose control of it. The vehi- cle/trailer combination could even rollover.
There is a risk of an accident.
On no account should you attempt to
straighten up the vehicle/trailer combination
by increasing the speed. Reduce vehicle
speed and do not countersteer. Apply the
brake as necessary. G
WARNING
If you install a ball 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 a risk
of an accident.
Only install the ball coupling delivered with
the vehicle or a ball coupling that is designed
to meet your trailer towing requirements. Do
not modify the ball coupling or the trailer tow hitch. G
WARNING
If the ball coupling is not installed correctly or not secured with the bolt provided and the
corresponding spring cotter, the trailer may
come loose. There is a risk of an accident.
Always install and secure the ball coupling as
described. Before every journey, ensure that
the ball coupling is secured with the bolt and
the corresponding spring cotter.
Please observe the manufacturer's operating instructions for the trailer coupling if a
detachable trailer coupling is used.
You will find the applicable permissible val-
ues, which must not be exceeded, in the vehi-
cle documents.
You will find the values approved by the man- ufacturer on the vehicle identification plates
and those for the towing vehicle in the "Tech-
nical data" section (Y page 346).
Couple and uncouple the trailer carefully. If
you do not couple the trailer to the towing
vehicle correctly, the trailer could become
detached.
Make sure that the following values are not
exceeded:
R the permissible trailer drawbar noseweight
R the permissible trailer load Towing a trailer

WARNING
Driving when your engine is overheated can
cause some fluids which may have leaked into the engine compartment to catch fire. You
could be seriously burned.
Steam from an overheated engine can cause
serious burns which can occur just by opening
the engine hood. Stay away from the engine if you see or hear steam coming from it.
Stop the vehicle in a safe location away from
other traffic. Turn off the engine, get out of the
vehicle and do not stand near the vehicle until
the engine has cooled down.
