Predictive speed adjustment
●
Always be prepared to adjust the speed
yourself
. If the trac sign recognition sys-
tem is not working properly or the navigation
data is not updated, the speed may change
unexpectedly and suddenly or may not be
suitable for the current trac situation. In
addition, the speed adjusted by the system
may not suit your driving style.
●
Always be prepared to adjust the speed
yourself. If you drive without any active gui-
ded route, if you leave the route calculated
by the navigation system or if the position of
the vehicle cannot be determined correctly
because the GPS does not provide accurate
data, the speed may change unexpectedly
and suddenly or may not adapt to the cur-
rent trac situation.
●
Always use up to date navigation data.
●
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 de-
tection system ›››page24 and the limitations
of the ACC, predictive speed adjustment has
the following limitations inherent to the system:
●
Predictive speed adjustment only recognises
trac 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 trac lights.
●
Trac 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 dat
a, or that are included with little accu-
racy, predictive speed adjustment is not availa-
ble.
●
If a speed limitation is notified based on the
navigation data without it being detected by
the trac 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 inf
otainment system, in the assist services
menu, you can individually adjust the type of
incident the vehicle should react to ›››page35:
●
Response to road layout.
●
Response at permitted speeds.
Driving with the predictive speed ad-
justment
●
Connect the ACC ›››page162.
●
Set the distance and speed.
●
Activate the predictive speed adjustment.
As soon as the syst
em recognises a speed limi-
tation 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 lim-
itation, 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
