Important safety notes The rear view camera is only an aid. It is not
a replacement for your attention to your
immediate surroundings. You are always
responsible for safe maneuvering and
parking. When maneuvering
or

parking, make
sure that there are no persons, animals or
objects in the area in which you are
maneuvering.
Under the following circumstances, the rear
view camera will not function, or will function
in a limited manner:
R the rear door is open
R in heavy rain, snow or fog
R at night or in very dark places
R if the camera is exposed to very bright light
R if the area is lit by fluorescent light or LED
lighting (the display may flicker) R
if there is a

sudden change in temperature,
e.g. when driving into a heated garage in
winter
R if the camera lens is dirty or obstructed
R if the rear of your vehicle is damaged. In
this event, have the camera position and
setting checked at a qualified specialist
workshop. Mercedes-Benz recommends
that you use an authorized Mercedes-Benz
Center for this purpose Driving systems

Differential locks
General 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, high-grip surfaces. G
WARNING
ABS, 4ETS, ESP ®
and BAS are deactivated
while the differential locks are engaged. 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, high-grip surfaces.
! 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
disconnected and the transfer case
differential lock is activated.
Otherwise, the transfer case can be
damaged.
Differential locks improve the traction of the
vehicle. Your vehicle is equipped with a differential
lock 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 and
differential locks 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
differential, a transmission in the drive train,
compensates for these different rotational
speeds, making cornering possible.
The disadvantage of a differential is that more
power is transferred to the wheels that have
the least grip. An example: a wheel of a driven
axle is on a snow-covered surface and
therefore does not have any traction. The
differential causes this wheel to be subjected
to the strongest driving force, as the flow of
force takes the path of least resistance. The
opposite wheel on this axle, however, which
stands on firm ground and could therefore
allow propulsion, receives no driving power.
4ETS compensates 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 RANGE off-road gear
also improves off-road capability.
Moreover, the more difficult conditions in off-
road driving require further measures such as
locking one or several differentials. Your
vehicle is equipped with three differential
locks: Off-road driving systems
201
Driving and parking Z

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
respective switch on the center console. If
the transfer case differential is disabled, the
front and rear wheels turn at the same speed.
If the differential for the rear axle is locked,
both rear wheels turn at the same speed,
regardless of their individual torques. Please
note that activating the differential locks
severely restricts the vehicle's steerability.
Please note that the functions of the
differential are absolutely necessary for
driving on paved roads. The differential locks
must never be engaged when driving on
paved roads. Otherwise, the vehicle may not
be steerable and you could lose control of the
vehicle. The differential locks must therefore
only be engaged when driving off-road. You
may only engage the differential locks if the
functions of the 4ETS and ESP ®
driving
systems and the LOW RANGE off-road gear
are insufficient.
i The differential locks are only available in
the LOW RANGE off-road gear.

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. Towing a trailer
203
Driving and parking Z

G
WARNING
When the vehicle/trailer combination begins
to lurch, you could lose control of it. The
vehicle/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
question 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
values, which must not be exceeded, in the
vehicle documents. You will find the values
approved by the manufacturer on the vehicle
identification plates and those for the towing
vehicle in the "Technical data" section
(Y page 349). 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
R the permissible rear axle load of the towing
vehicle
R the maximum permissible gross vehicle
weight of both the towing vehicle and the
trailer
When towing a trailer, your vehicle's handling
characteristics will be different in comparison
with when driving without a trailer.
The vehicle/trailer combination:
R is heavier
R is restricted in its acceleration and
gradient-climbing capability
R has an increased braking distance
R is affected more by strong crosswinds
R demands more sensitive steering
R has a larger turning circle
This could impair the handling
characteristics.
When towing a trailer, always adjust your
speed to the current road and weather
conditions. Do not exceed the maximum
permissible speed for your vehicle/trailer
combination.
General notes R
Do not exceed the legally prescribed
maximum speed for vehicle/trailer
combinations in the relevant country.
This lowers the risk of an accident.
R Only install an approved

trailer coupling on
your vehicle.
