Mercedes-Benz GLC : Driving and driving safety systems / Traffic Sign Assist

Function of Traffic Sign Assist

Traffic Sign Assist detects traffic signs with the multifunction camera. 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 recognize dangers.

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 restriction applies or if the system cannot clearly determine 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.

Additional sign with restriction

Vehicles with a standard Instrument Display: a + symbol next to a traffic sign in the Instrument Display indicates that additional traffic signs have been detected. These can also be displayed in the media display and optionally in the Head-up Display.

If Traffic Sign Assist cannot determine the maximum permissible speed (e.g. due to missing signs), the following display appears in the Instrument Display:

This is displayed continuously if the vehicle is in a country where Traffic Sign Assist is not supported. Traffic Sign Assist is not available in all countries.

Also observe the information on display messages in Traffic Sign Assist.

System limits

The system may be impaired or may not function particularly in the following situations:

• 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 heavy spray.
• If there is glare, e.g. from oncoming traffic, direct sunlight or reflections.
• If the windshield in the area of the multifunction camera is dirty, or if the camera is fogged up, damaged or covered.
• If the traffic signs are hard to detect, e.g. due to dirt or snow, because they are covered, or due to 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.
• If you turn sharply when passing traffic signs outside the camera's field of vision.

Setting Traffic Sign Assist

Requirements:

• Only vehicles with Driving Assistance Package:

  Active Distance Assist DISTRONIC and ECO Assist must be activated for the automatic adoption of speed limits.

Multimedia system:

Settings Assistance Traffic Sign Assist

Activating or deactivating automatic adoption of speed limits (only vehicles with Driving Assistance Package)

Select Limit Adoption.

If one of the following systems is activated, the detected speed can be manually adopted as the speed limit:

• Active Distance Assist DISTRONIC
• Cruise control
• Variable limiter

Displaying detected traffic signs in the media display
