The display can also be updated without a
visible traffic sign if:
R
the vehicle changes roads (e.g. motorway
exit or slip road)
R
a village or town boundary is passed which
is stored in the digital map
R
the last traffic sign detected by the camera
has not been repeated
If a sign indicating the end of a restriction
(speed limit or overtaking restriction) is
passed, the sign is displayed for five seconds.
The applicable traffic regulation then appears
in the instrument cluster.
The camera also detects traffic signs with a
restriction indicated by an additional sign
(e.g. in wet conditions).
The traffic signs are only displayed with the
restrictions if:
R
the regulation must be observed with the
restriction, or
R
Traffic Sign Assist is unable to determine
whether the restriction applies
If Traffic Sign Assist is unable to determine a
maximum permitted speed from any of the
available sources, no speed limit is displayed
in the instrument cluster either.
Traffic Sign Assist is not available in all coun-
tries. In this case, display : is shown in the
speedometer.
Important safety notes
Traffic Sign Assist is only an aid and is not
always able to correctly display speed limits
and overtaking restrictions. Traffic signs
always have priority over the Traffic Sign
Assist display.
The system may be either functionally
impaired or temporarily unavailable if:
R
visibility is poor, e.g. due to snow, rain, fog
or spray
R
there is glare, e.g. from the sun being low
in the sky
R
there is dirt, ice or misting on the wind-
screen in the area of the camera
R
traffic signs are hard to detect (dirt, ice,
snow)
R
there is insufficient illumination of the traf-
fic signs in the night
R
signs are ambiguous (e.g. traffic signs on
construction sites or in adjacent lanes)
R
the information in the digital street map of
the navigation system is incorrect or out of
date

remains active even when the display has
been deactivated.
