Rear view camera
General notes
Rear view camera :is in the trunk lid handle.
Rear view camera :is an optical parking and
maneuvering aid. It shows the area behind the
vehicle with guide lines in the multimedia sys-
tem.
The area behind the vehicle is displayed as a
mirror image, as in the rear view mirror.
iThe text shown in the multimedia system
depends on the language setting. The follow- ing are examples of rear view camera displays
in the multimedia system.
Important safety notes
The rear view camera is only an aid. It is not a
replacement for your attention to your immedi-
ate surroundings. You are always responsible
for safe maneuvering and parking. When maneu-
vering or parking, make sure that there are no
persons, animals or objects in the area in whichyou are maneuvering.
Under the following circumstances, the rear
view camera will not function, or will function in
a limited manner:
Rif the trunk lid is open
Rin heavy rain, snow or fog
Rat night or in very dark places
Rif the camera is exposed to very bright light
Rif the area is lit by fluorescent bulbs or LED

Traffic Sign Assist
General notes
Traffic Sign Assist displays the maximum speed
permitted to the driver in the instrument cluster.
The data and general traffic regulations stored in
the navigation system are used to determine the
current speed limit.
Traffic Sign Assist isa map-based system, and
for th isreason, traffic signs put up temporarily
(e.g. near roadworks) are not detected. There is also no display for changing traffic signs.
Traffic signs with a restriction indicated by an
additional sign (e.g. in wet conditions) are also
shown.
The sign indicating the end of a restriction only
appears with the restriction inthe instrument
cluster when:
Rthe regulation must be observed with the
restriction, or
RTraffic Sign Assist isunable to determine
whether the restriction applies
If Traffic Sign Assist is unable to determine a
maximum permitted speed from any of the avail-
able sources, no speed limit appears in the
instrument cluster either.

Traffic Sign Assist is not available in all coun-
tries. In this case, display:appears in the

Important safety notes
Traffic Sign Assist is only an aid and is not always
able to correctly display speed limits. Traffic
signs always have priority over the Traffic Sign
Assist display.
The system may be either functionally impaired
or temporarily unavailable if the information in
the digital street map of the navigation system is
incorrect or out of date.
Activating Traffic Sign Assist
XActivate the Traffic Sign Assist display using
the on-board computer (Ypage 222).
If you have activated the Traffic Sign Assist dis-
play in the on-board computer, the traffic regu-
lations (speed limits and overtaking restrictions)
appear in the instrument cluster for five seconds in each case. The wrong-way warning and the
traffic sign display for speed limits and overtak-
ing restrictions remain active even when the
display has been deactivated.

=Additional sign for unknown restriction
A maximum permitted speed of 80 mph
(80 km/h) and a speed limit of 60 mph
(60 km/h) with an unknown restriction apply.
The unit for the speed limit (km/h or mph)
depends on the country in which you are driving. It is generally neither shown on the traffic sign
nor on the instrument cluster but must be taken
into account when observing the maximum per-
mitted speed.
Night View Assist Plus
General notes
In addition to the illumination provided by the
normal headlamps, Night View Assist Plus uses
infrared light to illuminate the road. Night View
Assist Plus camera ;picks up the infrared light
and displays a monochrome image in the multi- function display. The image shown in the display
corresponds to a road lit up by high-beam head-
lamps. This enables you to see the road's course
