Traffic Sign Assist
General notes
Traffic Sign Assist displays the maximum speed
permitted to the driver in the instrument cluster.
The data stored in the navigation system and
general traffic regulations are used to determine
the current speed limit.
As Traffic Sign Assist is a map-based system,
traffic signs put up temporarily (e.g. near road-
works) are not detected.
