Deactivating the Adaptive Cruise Con-
tr
o
l ACC temporarily in certain situa-
tions
In the following situations the Adaptive
Crui
se Control (ACC) should be deactivated
due to the system's limitations ›››
:
●
When changing lanes, on tight bends and
rou
ndabouts, 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
cou
ld 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 situa-
tions.
Note
If you do not switch off the ACC in the afore-
mentioned sit
uations, you may commit a le-
gal offence.

The adaptive cruise control (ACC) has certain
ph
y
sical limitations inherent in the system.
For example, certain reactions of the ACC, in
certain circumstances, may be unexpected or
come late from the driver's point of view. So
pay attention in order to intervene if necessa-
ry.
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.
