Traffic Sign Assist
▌Function of Traffic Sign Assist
Traffic Sign Assist detects traffic signs with the
multifunction camera (
page 173). It assists
/
you by displaying detected speed limits and over-
taking restrictions in the Instrument Display.
Observe the notes on driving systems and your
responsibility; you may otherwise fail to recognise
dangers (
page 173).
/
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.
If the system detects that you are driving onto a
section of road in the wrong direction of travel, it
triggers a warning.
The camera also detects traffic signs with a
restriction indicated by an additional sign (e.g.
when wet). These are only displayed if a restric-
tion applies or if the system cannot clearly deter-
mine whether the restriction applies.
Warning when the maximum permissible speed is
exceeded
The system can warn you if you unintentionally
exceed the maximum permissible speed. Depend-
ing on the country, you can set in the multimedia
system by how much the maximum permitted
speed may be exceeded before a warning is given.
You can specify whether the warning is to be just
a visual warning or an acoustic one as well.
System limits
The system may be impaired or may not function
particularly in the following situations:
If there is poor visibility, e.g. due to insufficient
R
illumination of the road, highly variable shade
conditions, rain, snow, fog or heavy spray.
If there is glare, e.g. from oncoming traffic,
R
direct sunlight or reflections.
If there is dirt on the windscreen in the vicinity
R
of the multifunction camera or if the camera is
misted up, damaged or obscured.
If the traffic signs are hard to detect, e.g. due
R
to dirt, snow or insufficient lighting, or
because they are obscured.
Driving and parking 191
If the information on the navigation system's
R
digital map is incorrect or out of date.
If signs are ambiguous, e.g. road signs in road-
R
works or in adjacent lanes.
If you turn sharply when passing traffic signs
R
outside the camera's field of vision.
