vehicle. This also includes labeling and docu-
mentation affected by their modifications.
It is their responsibility to certify that:
R the altered vehicle conforms to all applica-
ble standards and regulations affected by
the vehicle alteration
R the altered vehicle continues to comply with
the motor vehicle safety standards and
emissions regulations
R the changes or installation of accessories do
not impair the safety of the vehicle
We are not responsible for any final certifica-
tion or claims regarding product liability or
warranty claims that arise as a result of such
changes. This applies to:
R components, assemblies or systems which
have been altered
R non-compliance with emissions laws and
regulations or with vehicle safety standards
arising as a result of the alterations
R all consequences resulting form the
changed, less safe or even defective vehicle
We do not assume responsibility as the final
stage manufacturer or the consequential prod-
uct liability.
Notes on the engine radiator Even seemingly small changes to the vehicle,
such as attaching a radiator trim for winter
driving or as protection against insects, are
not permitted. Do not cover the radiator. Do
not use thermal mats, insect protection covers
or anything similar.
Doing so can cause the diagnostics system to
display inaccurate values. Some of these val-
ues are legally required and must always be
correct.
Notes for commercial vehicles without
partitions Vehicles, which are approved as commercial
vehicles (N1), do not comply with the
ISO 27956
standard in the respective current
valid version unless equipped with a partition.
The ISO 27956 Standard details the equip-
ment for correct load securing in delivery vehi-
cles. Retrofitting the partition is strongly rec-
ommended when using the vehicle for the
transport of goods, as correct load securing in
vehicles without the partition is difficult to
achieve. Genuine Mercedes-Benz parts
! Air bags and Emergency Tensioning Devi-
ces, as well as control units and sensors for
these restraint systems, may be installed in
the following areas of your vehicle:
R doors
R door pillars
R door sills
R seats
R cockpit
R instrument cluster
R center console
Do not install accessories such as audio sys-
tems in these areas. Do not carry out
repairs or welding. You could impair the
operating efficiency of the restraint sys-
tems.
Have aftermarket accessories installed at a
qualified specialist workshop. H
Environmental note
We supply reconditioned assemblies and
parts which are of the same quality as new
parts. The same New Vehicle Limited War-
ranty applies as for new parts.
The operating safety of the vehicle could be
jeopardized if you use parts, tires and wheels
as well as accessories relevant to safety which
have not been approved by Mercedes-Benz.
This could lead to malfunctions in safety-rele-
vant systems, e.g. the brake system. Only use
genuine Mercedes-Benz parts or parts of equal
quality. Only use tires, wheels and accessories
that have been specifically approved for your
vehicle.
Mercedes-Benz tests genuine Mercedes-Benz
parts, conversion parts and accessories that
have been specifically approved for the type of
vehicle for:
R Reliability
R Safety
R Suitability
Despite ongoing market research, Mercedes-
Benz is unable to assess other parts. Even if
an independent or official approval has been
provided in exceptional cases, Mercedes-Benz
accepts no responsibility for the use of such
parts in Mercedes-Benz vehicles. 34

The rear view camera is a visual parking aid. It
shows you the area behind the vehicle in the
audio display.
The area behind the vehicle is displayed in a
mirrored fashion, as in the rear-view mirror or
the exterior mirrors. The guide lines displayed
assist you in backing up.
The message displays depend on the language
setting of the audio system. The following rear
view camera displays are examples.
Important safety notes !
Objects that are not at ground level appear
further away than they actually are, for
example:
R the bumper of the vehicle parked behind
R the drawbar of a trailer
R the ball coupling of a trailer tow hitch
R the tail-end of a truck
R slanted posts
Only use the camera guide lines for orienta-
tion. Do not get any closer to objects than
the lowest horizontal guide line. You may
otherwise damage your vehicle and/or the
object.
The rear view camera is only an aid. It cannot
replace your own awareness of the immediate
surroundings. You are responsible for safe
maneuvering and parking. Make sure that
there are no persons, animals or objects in the
maneuvering area while maneuvering and
parking in parking spaces.
The rear view camera may show obstacles in
perspectival distortion, incorrectly or not at all.
The rear view camera cannot display all
objects located very near and/or under the
rear bumper. It does not warn you of a colli-
sion, persons or objects.
Under the following circumstances, the rear
view camera will not function, or will function
in a limited manner:
R if the tailgate or rear-end door is open.
R if it is raining very heavily or snowing, or it is
foggy.
R at night or in very dark places.
R if the camera is exposed to very bright light.
White lines may appear in the camera image
R if the area is lit by fluorescent light, e.g.
from fluorescent lamps or LED lighting.
The camera image may flicker. R
if the camera lens fogs up, e.g. when driving
into a heated garage in winter, causing a
rapid change in temperature.
R the camera lens is dirty or obstructed.
Observe the notes on cleaning.
(Y page
267)
R if the rear of the vehicle is damaged.
In this case, have the camera position and
setting checked at a qualified specialist
workshop.
R the display has pixel errors.
Have the display repaired or replaced if usa-
bility is significantly reduced due to pixel
errors.
Do not use the rear view camera in these sit-
uations. You could otherwise injure others or
damage objects and the vehicle while parking
and maneuvering.
The field of vision and other functions of the
rear view camera may be restricted due to
additional accessories on the rear of the vehi-
cle (e.g. license plate holder, rear-mounted
bicycle rack).
Guide lines are always shown at road level. In
trailer mode, the guide lines are shown at the
level of the trailer coupling.
If you change wheel size, make sure they cor-
respond to the correct wheel size category
( Y page 278). If the category is changed with-
out recoding the control units in the vehicle,
the rear view camera cannot be precisely cali-
brated. The guide lines at road level or at the
level of the trailer tow hitch will not be dis-
played correctly.
In vehicles with a tailgate, the rear view cam-
era is protected from raindrops and dust by
means of a flap. When the rear view camera is
activated, this flap opens.
The flap closes again when:
R you have finished the maneuvering process
R you switch off the engine
For technical reasons, the flap may remain
open briefly after the rear view camera has
been deactivated. 164
