Traffic Sign Assist
Function of Traffic Sign Assist
Traffic Sign Assist aids you by displaying detected
speed limits and overtaking restrictions in the
instrument cluster.
Since Traffic Sign Assist also uses the data
stored in the navigation system, it can update the
display in the following situations without detect‐
ing traffic signs:
when the vehicle changes roads, e.g. motor‐
R
way exit or slip road
when a village or town boundary stored in the
R
digital map is passed
when the last traffic sign detected by the
R
camera has not been repeated
The camera also detects traffic signs with a
restriction indicated by an additional sign (e.g.
when wet).
%
Traffic signs are only displayed with the
restriction indicated by an additional sign in
the following cases:
the traffic signs must be observed with
R
the restriction
the system is unable to clearly determine
R
whether the restriction applies
If a sign indicating the end of a restriction for a
speed limit or overtaking restriction is passed,
the sign is shown for five seconds in the multi‐
function display. The applicable traffic regulation
then appears in the instrument cluster.
