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:
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
R
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:
if the tailgate or rear-end door is open.
R
if it is raining very heavily or snowing, or it is
R
foggy.
at night or in very dark places.
R
if the camera is exposed to very bright light.
R
White lines may appear in the camera image
if the area is lit by fluorescent light, e.g.
R
from fluorescent lamps or LED lighting.
The camera image may flicker.
if the camera lens fogs up, e.g. when driving
R
into a heated garage in winter, causing a
rapid change in temperature.
the camera lens is dirty or obstructed.
R
Observe the notes on cleaning.

if the rear of the vehicle is damaged.
R
In this case, have the camera position and
setting checked at a qualified specialist
workshop.
the display has pixel errors.
R
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:
you have finished the maneuvering process
R
you switch off the engine
R
For technical reasons, the flap may remain
open briefly after the rear view camera has
been deactivated.
