Rear view camera
Important safety notes
The rear view camera is only an aid. It cannot
replace your own awareness of the immediate
surroundings. You are responsible for safe
maneuvering, parking and pulling away. When
maneuvering, parking and pulling away, make
sure that there are no persons, animals or
objects in the maneuvering area.
The rear view camera is a visual parking aid.
Information on operation can be found in the
separate Audio 15 supplement.
The camera is in the middle of the roof above the
high-mounted brake lamp (
Y page 236).
You can find information on cleaning the camera
in the "Maintenance and care" section
(
Y page 236).
Working mode
ADR (working speed governor)
General notes
When activated, ADR automatically increases
the engine speed to a preset speed or a speed
you have set.
i
After a cold start, the idling speed of the
engine is increased automatically. If the pre-
set working speed is lower than the increased
idling speed, the working speed is only
reached once the engine has completed the
warm-up phase.
It is only possible to activate ADR with the
vehicle stationary and the parking brake
applied.
The selector lever of the automatic transmis-
sion must be in position P.
