— Audi pre sense front cannot overcome natu-
ral physical laws. It is a system designed to
assist and it cannot prevent a collision in ev-
ery circumstance. The driver must always in-
tervene. The driver is always responsible for
braking at the correct time. Do not let the
increased safety provided tempt you into
taking risks. This could increase your risk of
a collision.
— Audi pre sense front does not react to cer-
tain objects, such as animals, crossing or on-
coming vehicles, bars, railings, or railcars.
— Audi pre sense front may be limited or un-
available when driving in curves.
— Loose objects can be thrown around the ve-
hicle interior during sudden driving or brak-
ing maneuvers, which increases the risk of
an accident. Store objects securely while
driving.
