Traffic Sign Assist
Function of Traffic Sign Assist
Traffic Sign Assist detects traffic signs with the
multifunction camera ( page 171). It assists
/
you by displaying detected speed limits and
overtaking restrictions in the instrument cluster.
Observe the notes on driving systems and your
responsibility; you may otherwise fail to recog‐
nize dangers ( page 171).
/
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.
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. To do
this, you can specify in the multimedia system
by how much the maximum permissible speed
can be exceeded before a warning is issued. You
can specify whether the warning is to be just a
visual warning or an acoustic one as well.
