Traffic Sign Assist
General notes
Traffic Sign Assist displays the maximum
speed permitted and overtaking restrictions
to the driver in the instrument cluster. Driving
onto a section of road in the wrong direction
triggers a warning. Traffic Sign Assist detects
traffic signs with camera system : attached
behind the top of the windscreen. The data
and general traffic regulations stored in the
navigation system are also used to determine
the current speed limit.
If a traffic sign that is relevant to your vehicle
is passed, the display of the speed limits and
overtaking restrictions is updated.
