Traffic Sign Assist aids you by displaying detected speed limits and overtaking restrictions in the instrument cluster.
when the vehicle changes roads, e.g. motorway exit or slip road
when a village or town boundary stored in the digital map is passed
when the last traffic sign detected by the camera has not been repeated
The camera also detects traffic signs with a restriction indicated by an additional sign (e.g. when wet).
the traffic signs must be observed with the restriction
the system is unable to clearly determine whether the restriction applies
If a sign indicating the end of a restriction for a speed limit or overtaking restriction is passed, the sign is shown for five seconds in the multifunction display. The applicable traffic regulation then appears in the instrument cluster.
If the system detects that you are driving onto a section of road in the wrong direction of travel, it triggers a warning. This function is not available in all countries.
Traffic Sign Assist is only an aid and is not always able to correctly display speed limits and overtaking restrictions. The actual traffic signs always have priority over the Traffic Sign Assist display.
The Traffic Sign Assist display appears in the Assistance graphic menu of the on-board computer More.
The unit for the speed limit (km/h or mph) depends on the country in which you are driving. In general, it is not displayed either on traffic signs or in the instrument cluster. Always observe the legally required maximum permissible speed.
Traffic Sign Assist is not available in all countries. If it is unavailable, the following display is shown in the assistance graphic.
The system is affected by poor visibility, e.g. due to insufficient illumination of the road, highly variable shade conditions, or due to rain, snow, fog or heavy spray
The system is impaired by glare, e.g. from oncoming traffic, direct sunlight or reflections
The system is affected by dirt on the windscreen in the area of the multifunction camera, or because the camera is misted up, damaged or covered
The traffic signs are hard to detect, e.g. due to dirt, because they are covered, or due to snow or insufficient lighting
The system is affected by ambiguous signs, e.g. traffic signs on construction sites or in adjacent lanes
The information in the navigation system's digital map is incorrect or out-of-date
