Driver assistance

Driving situations
The situations to which the system reacts de-
pends on the vehicle speed.
Up to speeds of approximately 50 mph
(85 km/h), the system may react to the following
situations:
— Pedestrians and cyclists in your lane
Up to speeds of approximately 155 mph
(250 km/h), the system may react to the follow-
ing situations:
— A vehicle driving ahead clearly applies the
brakes
— When approaching a vehicle ahead that is clear-
ly traveling more slowly
— When approaching a stationary vehicle
Prewarning
To warn about detected dangers, Audi pre
sense o will appear in the instrument cluster
and an audio signal will sound.
A brief application of the brakes
If a collision is imminent, there may be an acute
warning using a brief application of the brakes.
You will also be warned about the danger by an
indicator in the instrument cluster display. You
may only be able to avoid a collision by swerving
or braking strongly.
Automatic braking force increase
If there is an impending collision and you are not
applying the brakes enough, the braking force
may be increased, depending on the situation.
Automatic braking
If you do not react to the acute warning, the sys-
tem may apply the brakes with strong braking
force within the limits of the system in order to
reduce the speed of impact in the event of a colli-
sion.
If the brakes were applied until the vehicle stop-
ped, © Please take over! will appear in the in-
strument cluster and you must take over control
of the vehicle.

ZA WARNING
— Observe the safety precautions and note the
limits of the assist systems, sensors, and
cameras > page 138.
— 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.
ONT Tee
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.

ZA WARNING
— Observe the safety precautions and note the
limits of the assist systems, sensors, and
