Driver assistance
— Audi pre sense cannot overcome natural
physical laws. It is a system designed to as-
sist
and it cannot prevent a collision in every
circumstance. The driver must always inter-
vene. 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 city does not react to certain
objects, such as animals, crossing or oncom-
ing vehicles, bars, railings, or railcars.
— Audi pre sense may be limited or unavailable
in curves or when it is dark.
— 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.
—Make sure that every passenger in the vehi-
cle has his or her safety belt fastened cor-
rectly and follows the instructions for prop-
er seating > page 63.
Certain system functions may not be available
if the ESC is limited or switched off
= page 115, if there is a malfunction, or if the
hill hold assist* is switched on > page 109.
Audi

Applies to: vehicles with Audi pre sense front
Audi pre sense front provides the same scope of
functions as Audi pre sense city, with a few ex-
ceptions page 147. The system has an exten-
sive field of view due to additional sensors that
are installed. Because of this, vehicles that are
braking or traveling significantly more slowly can
be detected earlier and more clearly, depending
on the limits of the system.
The following features apply to Audi pre sense
front:
— Automatic braking interventions are available
at vehicle speeds up to approximately 155 mph
(250 km/h)
~The system does not detect pedestrians

— Audi pre sense front does not react to cer-
tain objects, such as pedestrians, animals,
crossing or oncoming vehicles, bars, rail-
ings, or railcars.
Audi pre sense rear
Applies to: vehicles with Audi pre sense rear
Within the limits of the system, Audi pre sense
rear uses data from radar sensors at the rear cor-
ners of the vehicle and calculates the probability
of a rear-end collision with the vehicle behind
you.
Audi pre sense preemptive safety measures can
be initiated if the risk of a collision with the vehi-
cle behind you is detected.
— Observe the safety precautions and note the
limits of the assist systems, sensors, and
cameras > page 120.
—Audi pre sense rear does not react to pedes-
trians, animals, crossing objects, and ob-
jects not detected as vehicles.
