Deactivating the Adaptive Cruise
Control ACC temporarily in certain
situations
In the following situations the Adaptive Cruise
Control (ACC) should be deactivated due to
›››
the system's limitations
:
When changing lanes, on tight bends and
●
roundabouts, in acceleration and decelera-
tion lanes on motorways or in sections with
road works to prevent involuntary accelera-
tion to reach the programmed speed.
When going through a tunnel, as operation
●
could be affected.
On roads with several lanes, when other ve-
●
hicles are driving more slowly in the overtak-
ing lane. In this case, slower vehicles will be
overtaken on the right.
In case of heavy rain, snow or spray, as the
●
vehicle in front might not be detected proper-
ly or, in certain circumstances, might not be
detected at all.
WARNING
If the ACC does not switch off in the situa-
tions described, serious accidents and inju-
ries may occur.
Always switch off the ACC in critical sit-
●
uations.

Note
If you do not switch off the ACC in the
aforementioned situations, you may com-
mit a legal offence.

The adaptive cruise control (ACC) has cer-
tain physical limitations inherent in the sys-
tem. For example, certain reactions of the
ACC, in certain circumstances, may be unex-
pected or come late from the driver's point of
view. So pay attention in order to intervene if
necessary.
For example, the following traffic situations
call for the utmost attention:
Starting driving after a stopping phase
(only vehicles with automatic gearbox)
After a stopping phase, the ACC may begin
driving automatically when the vehicle in
›››
front drives off
