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. Asplit-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 seven split-screen views are:
R top view and picture from the rear view
camera (130 °viewing angle)
R top view and picture fro mthe front camera
(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 trailer view (vehicles with
trailer tow hitch)
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)
i The top view and trailer view are available
for vehicles equipped with a trailer tow
hitch.
When the function is active and you shift the
transmission from position Dor Rto N, you
see the previous view in the COMAND
display. The dynamic guidelines are hidden.
