Audi pre sense
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.
— 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.

Up to speeds of approximately 155 mph
(250 km/h), the system may react to the follow-
ing situations:
—Avehicle 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 1) / {@) will appear in the instrument clus-
ter 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 are applied until the vehicle is sta-
tionary, © / Please take over! will appear in
the instrument cluster and you must take over
control of the vehicle.
