Traffic Sign Assist detects traffic signs with multifunction camera 
and assists you by displaying detected speed limits and overtaking restrictions in the instrument cluster. If the system detects that you are driving onto a section of road in the wrong direction, it triggers a warning. The camera also detects traffic signs with a restriction indicated by an additional sign (e.g. in wet conditions).
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.

Traffic Sign Assist is not available in all countries. If it is unavailable, display is shown in the speedometer.
Vehicles with Driving Assistance Package: The system can warn you if you approach a pedestrian crossing with your vehicle. A message appears in the instrument cluster.
The warning occurs if appropriate traffic signs or road markings are recognised and pedestrians are present in the danger zone.
If there is poor visibility, e.g. due to insufficient illumination of the road, if there are highly variable shade conditions or in rain, snow, fog or spray
if there is glare, e.g. from oncoming traffic, direct sunlight or reflections from other vehicles
if the windscreen in the area of the multifunction camera is dirty, or if the camera is misted up, damaged or covered
if the traffic signs are hard to detect, e.g. due to dirt or snow, or because they are covered or because of insufficient lighting
if the information in the navigation system's digital map is incorrect or out-of-date
if the signs are ambiguous, e.g. traffic signs on construction sites or in adjacent lanes
