nction of there ar view camera If
yo u ha veactivated the function in the multime‐
dia sy stem, the image from rear view camera 1
appears in the multimedia sy stem when reve rse
ge ar is selec ted. Dynamic guide lines show the
path theve hicle will take with thesteering wheel
in its cur rent position. This helps youto orient
yo urself and toavo id obs tacles when ba cking up.
The image from rear view camera 1appears in
th e multimedia sy stem when thefo llowing condi‐
tions are fulfilled:
R The ignition is switched on.
R Reversege ar has not been engaged.
R The rear-end doors are opened.
This means that the area behind theve hicle can
be monitored.
When there ar-end doors are closed, the image
from there ar view camera is swit ched off af ter
appr oximately ten seconds.
The rear view camera is only an aid. It is not a
substitute foryo ur attention tothe sur roundings.
The responsibility for safe maneu vering and pa rk‐
ing remains with you. Make sure that there are no
persons, animals or objects etc., in the maneu‐
ve ring area while maneuvering and pa rking.
The rear view camera may show a dis torted view
of obs tacles, show them incor rectly or not at all.
The rear view camera cannot display all objects
which are very near toor under there ar bumper.
It will not warnyou of a collision, people or
objects.
Yo u can select from thefo llowing vie ws:
R Norma l view R
Wide-angle view
R Trailer view
The area behind theve hicle is displa yed as a mir‐
ro r image, as in the inside rearview mir ror.
Sy stem limitations
The rear view camera will not function or will only
partially function in thefo llowing situations:
R There is heavy rain, snow or fog.
R The ambient light is poor, e.g. at night.
R The area is lit byfluorescent light (the displ ay
may flic ke r).
R Ifth ere is a sudden change in temp erature,
e.g. when driving into a heated garage in win‐
te r.
R The ambient temp erature is very high.
R The camera lens is obstructed, dirty or fogged
up. Obser vethe no tes on cleaning there ar
view camera (/ page212).
R The camera or rear of your vehicle is dam‐
