obstacle present. The PARKTRONIC sensors are dirty or iced up.
X Clean the PARKTRONIC sensors (Y page 268).
X Turn the key to position 2again in the ignition lock. The license plate or other parts attached near the sensors may not
be secured correctly.

Important safety notes !
Objects that are not at ground level
appear further away than they actually are, for example:
R 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 Only use the image from the rear view cam-
era as a guide. You may otherwise damageyour vehicle and/or the object.
The rear view camera is only an aid. It cannot
replace your own awareness of the immedi-
ate 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. Driving systems
