The system brakes the vehicle to avoid over-
taking on the right, and will avoid overtaking
based on speed. The driver can interrupt the
intervention of the ACC by pressing the ac-
celerator. At low speeds the function is inac-
tive, for greater comfort in a traffic jam or in
city traffic.
Deactivating the ACC temporarily
in certain situations
In the following situations the ACC should be
deactivated due to the system's limitations
›››
:
When overtaking, on closed curves or
●
mountain roads, roundabouts, slip roads or
roadwork sections, preventing the system
from accelerating to reach the programmed
speed.
When going through a tunnel, as operation
●
could be affected.
When other vehicles are going slower in the
●
left lane. In this case, slower vehicles will be
overtaken on the right.
In case of heavy rain, snow or fog, the vehi-
●
cle in front may not be detected.
WARNING
If the ACC does not switch off in the situa-
tions described, serious accidents and inju-
ries may occur.
Driver assistance systems

●
uations.
