with high cornering speeds or high rates of
acceleration

than 80 km/h or faster than 180 km/h

warned again after 15 minutes at the earliest.

Speed Limit Assist
Important safety notes
Speed Limit Assist shows you detected speed
limits in the multifunction display. Data from
the navigation system is also used for this
purpose. The display appears if a traffic sign
indicating a speed limit or the end of a speed
limit is detected. If Speed Limit Assist does
not detect any traffic signs, the speed limit
from the digital road map is taken and shown
in the display.
Speed Limit Assist detects the traffic signs
with a camera attached behind the top of the
windscreen.
