●
Always take into account the speed limit. In
the case of speed limits that are not included
in the navigation data, the speed limit may
be exceeded.

Also note the information related to the ACC

Limitations of the predictive speed
adjustment
In addition to the limitations of the road sign de-
tection system and the limitations of the ACC,
predictive speed adjustment has the following
limitations inherent to the system:
●
Predictive speed adjustment only recognises
road signals that show a speed limit. The pre-
dictive speed adjustment does not take into
account, above all, the rules on priority of pas-
sage or trac lights.
●
Road 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 low accu-
racy, predictive speed adjustment is not availa-
ble.
●
If a speed limit is
notified based on the nav-
igation data without it being detected by the
road signal detection system, the indicated
speed will be adjusted to the speed that was
saved the last time.
●
Predictive speed adjustment is not available
for speed limits below approx. 20 km/h (approx.
15 mph). In this case, a relevant message is dis-
played on the instrument cluster display.
Activating the predictive speed ad-
justment
In the infotainment system, in the assist services
menu, you can individually adjust the type of in-
cident the vehicle should react to ›››page39:
●
Response to road layout.
●
Response at permitted speeds.
Driving with predictive speed adjust-
ment
●
Connect the ACC ›››page201.
●
Set the distance and speed.
●
Activate the predictive speed adjustment.
As soon as the system recognises a speed limit
or a relevant road layout during the route, a
warning will appear on the instrument cluster
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 limit.
Adjustment due to a road layout.
In the event of adjustment due to a speed limit,
the detected speed will be saved as the new
desired speed. In the event of adjustment due
to the road layout, the vehicle will accelerate
again after leaving the reason for the adjust-
ment behind and the speed will be adjusted to
the saved speed.
The speeds indicated for curves depend on the
drive profile›››page183.

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