Traffic Sign Assist detects traffic signs with the
multifunction camera and compares this with
information in the digital navigation map. It assists
you by displaying detected speed limits and over-
taking restrictions in the driver's display and in
the head-up display. The system can issue a warn-
ing when you exceed the maximum permissible
speed.
In some countries, the system can provide you
with further functions and can warn you when you
are approaching pedestrian crossings or when
you are about to drive past stop signs or red lights
unintentionally.
The camera also detects and analyses traffic
signs with a restriction indicated by an additional
sign (e.g. when wet).
