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 traffic signs:
When the vehicle changes roads, e.g. free‐
R
way entry or exit road.
When a village or city boundary is passed
R
which is stored in the digital map.
The camera also detects traffic signs with a
restriction indicated by an additional sign (e.g. in
wet conditions).
Warning when the maximum permissible
speed is exceeded
The system can warn you if you unintentionally
exceed the maximum permissible speed. To do
this, you can specify in the multimedia system
by how much the maximum permissible speed
can be exceeded before a warning is issued. You
can specify whether the warning is to be just a
visual warning or an acoustic one as well.
