Adjustment due to a speed limitation.
Adjustment due to a road layout.
In the event of adjustment due to a speed lim-
itation, the detected speed will be saved as
the new desired speed. In the event of adjust-

accelerate again after leaving the reason for
the adjustment behind and the speed will be

Note
●
When a speed limit
ation is recognised,
the proactive speed adjustment also
+
–
adapts the saved speed even if the ACC is
s
witched off. However, it will not adjust.
●
If the speed of travel considerably ex-
ceeds the speed limit detected by the traf-
fic signal detection system, a relevant
warning is displayed in the instrument pan-
el display.
●
In the event of joining a highway without
speed limitation, the recommended speed
is automatically saved as the desired
speed. If a higher speed has previously
been saved for a motorway without a
speed limit, this is used instead of the rec-
ommended speed.
