Audi pre sense front
Description
A pp lies to veh icles: with Audi pre sense front or Audi adapt ive
cr uise control
Pre sense front informs you if the distance to the
vehicle ahead falls below the safe distance for an
extended period of time.
It c an warn of a poss i
b le co llision and initiate braki ng maneuve rs,
within the limits of the system.
When detected in time, the system can assess
dangerous s ituations where an object ahead
b rakes suddenly or if your own vehi cle is t raveling
at a high speed and approaching an object that is
mov ing more slowly. If detect ion is not possible,
then pre sense front does not react.

able to avoid a collision. The indicator light .
indicates this.
- T he
approach w arning occurs when an object
ahead is traveling more slowly or brakes
strong ly. When this warning occurs, it may only
be possible to avoid a coll is ion by swerving or
braking strongly. The message

about the danger. For vehicles with adaptive
cruise control, the. indicator light also turns

If you do not react enough or not at all to a da n
gerous s ituation that was detected by the sys
