General notes

The area behind the vehicle is displayed as a
mirror image, as in the rear view mirror.
i The text shown in the Audio/COMAND
display depends on the language setting.
The following are examples of rear view
camera messages in the Audio/COMAND
display.
Observe the notes on cleaning ( Y

if the area is lit by fluorescent bulbs 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
