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 multifunction camera :
attached at the top of the windscreen. The
data and general traffic regulations stored in
the navigation system are also used to deter-
mine 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.
The display can also be updated without a
visible traffic sign if:
the vehicle changes roads (e.g. motorway
R
exit or slip road)
a village or town boundary is passed which
R
is stored in the digital map
the last traffic sign detected by the camera
R
has not been repeated
