Introduction
Applies to: vehicles with Audi pre sense
Within the limits of the system, the Audi pre
sense functions can initiate measures in certain
driving situations to protect the vehicle occu-
pants and other road users. Depending on the ve-
hicle equipment, various Audi pre sense systems
may
be installed:
— Audi pre sense basic can react during emergen-
cy and dangerous braking maneuvers and un-
stable driving situations (such as oversteering
or understeering).
— Audi pre sense city and Audi pre sense front
can detect an impending frontal impact and re-
act with warnings, braking interventions, and
preemptive safety measures for the vehicle oc-
cupants.
152
— Audi pre sense rear monitors the rear traffic
behind your vehicle and can react to an impend-
ing rear impact.
— The swerve assist can help you to steer the ve-
hicle around an obstacle during an evasive ma-
neuver that is detected as critical.
— The turn assist can detect vehicles in the oppo-
site lane as critical during a turning maneuver
and react with braking maneuvers.

ceptions > page 153. 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

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.

off if there is a malfunction in the side assist
system.
Swerve assist
Applies to: vehicles with swerve assist

The swerve assist can help you to steer the vehi-
cle around an obstacle detected in a critical area.
If you avoid an obstacle after the acute warning,
then the swerve assist assists you by applying
slight steering adjustment to correct your steer-
ing wheel angle as long as you are actively steer-
ing. Swerve assist is available at speeds between
approximately 20 mph (30 km/h) and 90 mph
(150 km/h).
