General notes Rear view camera
0043is in the trunk lid handle.
Rear view camera 0043is an optical parking and
maneuvering aid. It shows the area behind
your vehicle with guide lines in the COMAND
display.
The area behind the vehicle is displayed as a
mirror image, as in the rear view mirror.
i The text of messages shown in the
COMAND display depends on the language
setting. The following are examples of rear
view camera messages in the COMAND
display. 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
if the trunk lid 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.
Observe the notes on cleaning
(Y page 358)
R if the rear of your vehicle is damaged. In
this event, have the camera position and
setting checked at a qualified specialist
workshop
The field of vision and other functions of the
rear view camera may be restricted due to
additional accessories on the rear of the
vehicle (e.g. license plate holder, bicycle
rack).
i The rear view camera 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

Object detection
The rear view camera can detect moving and
stationary objects. If, for example, a
pedestrian or another vehicle is detected,
these objects are marked with bars. The
system is only able to detect and mark
stationary objects when your vehicle is
moving. By contrast, stationary objects will
always be detected and marked.
To ensure that you can use the function, it
must be switched on in COMAND (see the
separate operating instructions). 360° camera (surround view)
General notes The 360° camera is a system consisting of
four cameras.
The system analyzes images from the
following cameras:
R Rear view camera
R Front camera
R Two cameras in the exterior rear view
mirrors
The cameras capture the immediate
surroundings of the vehicle. The system
supports you, e.g. when parking or if vision is
restricted at an exit.
The 360° camera images can be shown in full
screen mode or in seven different split-screen
views on the COMAND display. A split-screen
view also includes a top view of the vehicle.
This view is calculated from the data supplied
by the installed cameras (virtual camera).
The six split-screen views are:
R top view and picture from the rear view
camera (130° viewing angle)
R top view and image from the front camera
(130° viewing angle without displaying the
maximum steering wheel angle)
R top view and enlarged rear view
R top view and enlarged front view R
top view and pictures from the rearward
facing mirror cameras (rear wheel view)
R top view and pictures from the forward
facing mirror cameras (front wheel view)
When the function is active and you shift the
transmission from position Dor Rto N, you
see the view which was active before the
360° view in the COMAND display. The
dynamic guidelines are hidden.
When you change between transmission
positions Dand R, you see the previously
selected front or rear view.
Important safety notes The 360°camera is only an aid and may show
a distorted view of obstacles, show them
incorrectly or not at all. The 360°camera is
not a substitute for attentive driving.
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.
You are always responsible for safety, and
must always pay attention to your
surroundings when parking and
maneuvering. This applies to the areas
behind, in front of and beside the vehicle. You
could otherwise endanger yourself and
others.
The 360° camera will not function or will
function in a limited manner:
R
if the doors are open
R if the exterior mirrors are folded in
R if the trunk lid is open
R in heavy rain, snow or fog
R at night or in very dark places
R if the cameras are exposed to very bright
light
R if the area is lit by fluorescent light or LED
lighting (the display may flicker)
R if the camera lenses fog up, e.g. when
driving into a heated garage in winter,
