The function of the pre sense basic is activated at
a speed of 20 mph (30 km/h) or higher . The de-
ployment time is adapted in the drive select dy-
namic mode .

& WARNING
-
-
Pre sense cannot overcome natural physical
laws .
It is a system designed to assist and it
cannot prevent a collision. Do not let the in-
creased safety provided tempt you into tak ing
risks. This could increase your risk of a colli-
sion.
- The system can dep loy incorrectly.
- Please note that t he sensors do not always
detect all objects. This increases the risk of
a collision.
- Pre sense does not react to peop le or ani-
mals or objects that are crossing the vehi-
cle's path or are difficult to detect
¢page 95.
- Reflective objects such as gua rd rails or the
entrance to a tunnel, heavy rain and ice can
affect the funct ion of the radar sensors and
the system's ability to detect a collision risk.
@ Note
The sensors can be displaced by impacts or
damage to the bumper, wheel housing and
underbody. Pre sense can be impaired by this .
Have an autho rized Audi deale r or autho rized
Audi Service Facility check the ir funct ion. .,.
