Traffic Sign Assist
Function of Traffic Sign Assist
Traffic Sign Assist detects traffic signs with mul‐
tifunction camera 1. It assists you by display‐
ing detected speed limits and overtaking restric‐
tions 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
detecting traffic signs:
When the vehicle changes roads, e.g. on a
R
freeway entry or exit road.
When a village or city boundary which is
R
stored in the digital map is passed.
The camera also detects traffic signs with a
restriction indicated by an additional sign (e.g. in
wet conditions).
%
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.
Traffic Sign Assist is only an aid. The driver is
responsible for keeping a safe distance from the
vehicle in front, for vehicle speed and for braking
in good time.
