Speed Limit Assist detects speed limits with multifunction camera and displays them in the driver's display and optionally in the head-up display. The camera also detects speed limits with a restriction indicated by an additional sign (e.g. when wet).
Observe the notes on driving systems and your responsibility; you may otherwise fail to recognise dangers More.
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 More.
Traffic signs which have an impact on the maximum permissible speed, e.g. signs indicating the beginning or end of dual carriageways, can also be detected.
If Speed Limit Assist cannot determine the current maximum permissible speed (e.g. due to missing signs), the following display appears in the driver's display:
This is displayed continuously if the vehicle is in a country where Speed Limit Assist is not supported. Speed Limit Assist is not available in all countries.
If visibility is poor, e.g. due to insufficient illumination of the road, highly variable shade conditions, rain, snow, fog, swirling dust or heavy spray.
If there is glare, e.g. from oncoming traffic, direct sunlight or reflections.
If the windscreen in the area of the multifunction camera is dirty, or if the camera is misted up, damaged or covered.
If traffic signs are difficult to detect, e.g. due to dirt, snow, ice, insufficient lighting or driving too close to the vehicle in front, or because they are covered, faded, damaged, badly positioned or twisted.
Digital LED traffic signs may not be detected correctly or at all due to technical factors, such as transmission frequency.
If signs or the road layout is ambiguous, e.g. traffic signs in roadworks, at exits and ramps, in neighbouring lanes or parallel roads.
If signs do not conform to the standard.
If signs or road layouts are specific to the country, for example, at or beyond construction sites.
After sharp turns and tight bends, when traffic signs are outside the camera's field of vision.
If you overtake vehicles with traffic signs which are affixed or attached to them.
If you are using transport equipment secured with a trailer coupling, such as a bicycle rack, the system may react to restrictions for car/trailer combinations.
