Prewarning
To warn about detected dangers, Audi pre
sense [J 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, [J Please take over! will appear in the in-
strument cluster and you must take over control
of the vehicle.
