●
Always take into account the maximum
permitted speed. In the case of speed limita-
tions that are not included in the navigation
data, the maximum permitted speed may be
exceeded.

Limitations of the predictive speed
adjustment
In addition to the limitations of the road sign
detection system and the limitations of the
ACC, predictive speed adjustment has the fol-
lowing limitations inherent to the system:
●
Predictive speed adjustment only recognises
traic signals that show a speed limitation. The
predictive speed adjustment does not take into
account, above all, the rules on priority of pas-
sage or traic lights.
●
Traic signs that indirectly show a speed re-
striction, e.g. signs at the entrance to towns,
are only recognised on the basis of navigation
data.
●
On roads that are not included in the naviga-
tion data, or that are included with little accu-
racy, predictive speed adjustment is not availa-
ble.
●
If a speed limitation is
notied based on the
navigation data without it being detected by
the traic signal detection system, the indica-
ted speed will be adjusted to the speed that
was saved the last time.
●
Predictive speed adjustment is not available
for speed limitations below approx. 20 km/h
(approx. 15 mph). In this case, a relevant mes-
sage is displayed on the instrument panel
screen.
Activating the predictive speed ad-
justment
In the infotainment system, in the assist serv-
ices menu, you can individually adjust the
type of incident the vehicle should react to
›››page39:
●
Response to road layout.
●
Response at permitted speeds.
Driving with the predictive speed
adjustment
●
Connect the ACC ›››page205.
●
Set the distance and speed.
●
Activate the predictive speed adjustment.
As soon as the system recognises a speed lim-
itation or a relevant road layout during the
route, a warning will appear on the instrument
panel display. This warning will indicate the
reason and the speed to which the vehicle will
adjust due to said limitation.
Adjustment due to a speed limitation.
Adjustment due to a road layout.
In the event of adjustment due to a speed
limitation, the detected speed will be saved as
the new desired speed. In the event of adjust-
ment due to the road layout, the vehicle will
accelerate again after leaving the reason for
the adjustment behind and the speed will be
adjustment to that which has been saved.
The speeds indicated for curves depend on
the driving prole›››page185.

Adjust the announced speed
The announced speed can only be adjusted in
the event of adjustment due to a speed limita-
tion.
