Traffic Sign Assist
Function of Traffic Sign Assist
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:
When the vehicle changes roads, e.g. slip
R
road or motorway exit.
When a village or town boundary which is
R
stored in the digital map is passed.
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. in
wet conditions).
Traffic Sign Assist is only an aid. The driver is
responsible for keeping a safe distance to the
vehicle in front, for vehicle speed and for braking
in good time.
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.

Display in the instrument display
Traffic Sign Assist is not available in all coun‐
tries. If it is unavailable, display
the speedometer.
System limitations
The system may be impaired or may not function
in the following situations:
If there is poor visibility, e.g. due to insuffi‐
R
cient illumination of the road, if there are
highly variable shade conditions or in rain,
snow, fog or heavy spray.
If there is glare, e.g. from oncoming traffic,
R
direct sunlight or reflections.
If the windscreen in the area of the multi‐
R
function camera is dirty, or if the camera is
misted up, damaged or covered.
If the traffic signs are hard to detect, e.g. due
R
to dirt or snow, or because they are covered
or due to insufficient lighting.
If the information in the navigation system's
R
digital map is incorrect or out-of-date.
If the signs are ambiguous, e.g. traffic signs
R
on construction sites or in adjacent lanes.
