Speed Limit Assist uses OpenStreetMap data,
which is made available under the conditions
of the Open Database License (OBbL). Further
information can be found at: https://
www.osmfoundation.org/wiki/licence.
Speed Limit Assist detects speed limits with a
multifunction camera and displays them in the
instrument cluster 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). The system detects stop signs,
thereby preventing the engine from being
switched o by the ECO start/stop function.
Observe the notes on driving systems and your
responsibility; you may otherwise fail to recognise
dangers ( page 223).

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.

direct sunlight or re ections.
If the windscreen in the area of the multifunc-
