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 and optionally in
the Head-up Display.
Since Traffic Sign Assist also uses the data
stored in the navigation system, it can update
the display in the following situations without
detecting traf fic signs:
R
When the vehicle changes roads, e.g. a free‐
way entry or exit road.
R
When a village or city boundary which is
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 Sign Assist is only an aid. The driver is
responsible for keeping a safe distance to the
vehicle in front, for vehicle speed and for braking
in good time. The maximum permissible speed
also depends on factors such as the road sur‐
face and traffic conditions.
Warning when the maximum permissible
speed is exceeded
The system can warn you if you unintentionally
exceed the maximum permissible speed. To do
