Audi pre sense
Introduction
Applies to: ve hicles w ith Audi p re se nse
W ith in the limits of the system, the pre sense
functions can in it iate measures in particularly
dangerous s ituat ions to protect the ve hicle pas
sengers and ot her r oad users.
- Due to the interl ink ing of various vehicle sys
tems , crit ica l dr iv ing s ituat ions can be detected
by
pr e s ense basic and measu res fo r preventa
t ive occ upan t protect ion are can be initiated.
- T he
pre sen se front system uses the data from
t h e adapt ive cr uise control* radar sensors and
t h e camera to calc ulate the probab ility of a col
lision . Within the limits of the system, an im
pending collision with vehicles can be detected
in both urban and rural speed ranges. In this
case, the system warns the driver visually,
acoustically and with a jerk on the brakes if nec
essary . If needed, it can initiate a partial or fu ll
deceleration to reduce the collision speed or to
avo id the co llision unde r ce rtain c ircumstances .
In conjunct ion with p re sense basi c/rear, the
front safety belts are also revers ibly tensioned
whe n needed. The pre sense front is also act ive
when adaptive cruise control* is switched o ff.
- Pr e se nse rear con tains pre sense basic func
tions. It uses the data from the side assist* ra
dar sensors and calc ulates within the limits of
the system the probability of a rear end colli
sion with the vehicle behind you . Pre sense rear
is also active when s ide assist* is switched off .

-Within the limits of the system, pre sen se cit y
uses the camera data and can detect an im
pending collision with vehicles and pedestrians .
In this case, the system warns the driver visual ly, acoustical ly and w it h a jerk on the brakes if
necessary . If needed, it ca n initiate a full dece l
erat ion to reduce t he coll is ion speed or to avoid
the collision under certa in circumstances . In
conjunction with p re sense basi c/rear, the front
safety belts are a lso reve rsibly te nsioned whe n
needed.

(D Tips
- C erta in p re sense funct io ns sw itch off when
driving in reve rse.
- Th e pre sense f unct io ns m ay no t be ava ila
ble i f th ere is a ma lfunct ion in the ESC sys
tem or t he airbag control module .
-Note that the reve rsib le belt tens ione r o n
the front passenger 's side deactivates when
the front passenger's airbag is deactivated.
- Switch the pre sense off when yo u are not
using public streets or when loading the ve
hicle onto a vehicle carrier, train, ship or
other type of transportat ion. This can pre
vent an undesired intervention from the pre
sense system.
Audi pre sense basic
App lies to: vehicles wit h Audi pre sense basic
The pre se nse bas ic functions are activated at a
speed of approx imately 20 mp h (30 km/h) o r
highe r.
The following functions ca n be triggered u nder
certain co nd it io ns w it hi n the lim its of the sys
tem:
- Tensioning of the safety belts (for examp le,
during heavy brak ing) : the front safety belts
have reversible belt te nsioners . If a collision
does not occur , the safety belts loosen slig htly
and are ready to tr igger aga in.
