Audi pre sense
Introduction
Applies to: ve hicles with Audi pre sense
W ith in the lim its of the system, t he pre sense
f u nctions can init iate measures in part icularly
dangerous sit uat ions to protect t he ve hicle pas ­
sengers and ot her road users.
- Because different veh icle systems such as the
ESC are i nterconnected , the
pre sense b asic in ­
t roduces p reempt ive safety meas ures for the
Assist
passengers i f an unstable driving si tuation is
detected.
- The
pre sen se front system uses the data from
the adaptive cruise contro l* radar sensors and
the camera to ca lculate the probability of a co l­
lision . With in the lim its of the system, an im­
pending co llision with vehicles can be detected
in both urba n and rural speed ranges. In t his
case, the system warns the driver visua lly,
acoust ica lly and w ith a jerk on the brakes if nec­
essary. If needed, i t can in itiate a partia l o r fu ll
dece lerat ion to reduce the collision speed or to
avoid the collision under certa in circumstances.
I n conjunction with pre sense basic/rear, the
front safety belts are a lso reve rsibly tens ioned
when needed . The pre sense front is a lso active
when adaptive cruise control* is sw itched off.
- Pre sense rear contains pre sense basic func­
tions. It uses the data from the side assist* ra ­
dar sensors and ca lculates within the limits of
the system the probability of a rear end colli­
sion with t he vehicle behind you. Pre sense rear
is also act ive when side assist* is sw itched off .
- Within the limits of the system,
pre sense city
uses the camera data and can detect an im­
pe nding collision with vehicles and pedestrians.
I n th is case , the system warns the driver visua l­
ly , acous tic ally and wit h a jerk on the b rakes if
necessary. If needed, it c an initi ate a full dece l­
erat io n to reduce the collis io n speed or to avoid
the collision under certain circumstances . In
conjunction with pre sense basic/rear, the front
safety belts are a lso reversibly tens ioned when
needed .
A WARNING
-
Read the genera l information on¢.&. in Gen -
eral information on page
97, c::> .&. in General
information on page 117 .
@ Tips
-Certa in pre sense funct ions sw itch off when
dr iving in reverse.
- The pre sense funct ions may not be availa­
ble if there is a malfunct ion in the ESC sys­
tem or t he a irbag control module .
107

Ass is t
- Note that the reversible belt tensioner on
the front passenger's side deactivates when
the front passenger's a irbag is deactivated.
- Switch the pre sense off when you are not
using public streets or when loading the ve­
hicle onto a vehicle carrier, train, ship or
other type of transportation. This can pre­
vent an undes ired intervention from the pre
sense system .
Audi pre sense basic
Description
Applies to: vehicles with Aud i pre sense basic
The pre sense basic functions are activated at a
speed of approximately 20 mph (30 km/h) or
h igher.
The fo llowing functions can be triggered unde r
certain conditions within the limits of the sys­
tem:
- Tensioning of the safety belts (for example,
during heavy braking): the front sa fety belts
have reversible belt tensioners . If a collision
does not occur, the safety belts loosen slightly
and are ready to trigger again.
- The emergency flashers activate
1) , the win ­
dows and the sunroof* close (for example when
under- or oversteering) : the clos ing process for
the windows and the sunroof* in itiates.

W ith in the lim its of the system, pre sense front
can wa rn you of impending coll is ions and initiate

If detected in time, the system can rank the dan ­
gerous situation as critical if a vehicle driving
ahead brakes suddenly, if your own veh icle is ap­
proaching a significant ly slower veh icle at h igh
speed or when there is an oncoming veh icle dur­
i ng a turning maneuver .
If detection is not possible, then pre sense front
does not react.
Warnings

F ig . 104 Instrument cl uster : approach warning
G eneral information
The system recognizes various dangerous situa ­
tions. The
early w arning occurs when:
- a vehicle d riving ahead bra kes sudde nly,
- your own veh icle approaches a sign ificant ly
slower ve hicle or stationa ry vehicle in the direc­
tion of trave l.
When this warn ing occurs, it may o nly be possi ­
ble to avo id a collision by swerving or braking
strongly. The message

~ fig. 104 and a wa rning tone will warn you
abo ut the dange r.
If you do not react enough or no t at all to a dan­
gerous s ituation that was detected by the sys­
tem, p re sense front provides assis tance by ap ­
ply ing the b rakes .
If a collision is imminent, the system will fi rst
provide an
a cute warning by b raking sharply. You
will a lso warned by an indica to r in the instrument
cl us ter disp lay ~

the acute warning, pre sense front can brake with

increasing force within the limits of the
system
l)_ This reduces the vehicle speed in the
event of a collision. At low vehicle speeds, pre
sense front can initiate a complete deceleration
shortly before a collision with a vehicle driving
ahead
1>. If pre sense front determines that you
are not braking strongly enough when a collision
is imminent, it can increase the braking force .
The following functions trigger in conjunction
with pre sense basic/rear at corresponding vehi ­
cle speeds :
- Reversible tensioning of the front safety belts.
- Closing the windows and sunroof*.
- Inflating the side bolsters* in the seat backrest
and seat surface.
Audi drive select*: the reversible belt tensioner,
the closing of the windows and sunroof* as well
as the inflating of the side bolste rs* on the seat
backrest and seat surface are not active depend­
ing on the mode selected .
Collision avoidance assist
Collision avoidance assist helps you to steer the
vehicle around an obstacle in a critical situation.
If you avoid an obstacle after the acute warning,
then the collision avoidance supports you by ap­ plying slight steering adjustment to correct your
steering wheel angle as long as you are actively
steering. Collision avoidance assist is available at
speeds between approximately 20 mph (30 km/
h) and 90 mph (150 km/h).
Turn assist
When starting to drive and up to speeds of maxi­
mum 6 mph (10 km/h), the turn assist uses a
braking intervention to prevent your vehicle from
colliding with an oncoming vehicle when turning left or right (available in certain countries) . The
braking intervention causes your vehicle to stay
in its lane.
.8, WARNING
-Pre sense front cannot overcome the laws of
physics.
It is a system designed to assist and

Assist
it cannot prevent a collision in every circum­
stance. The driver must always intervene.
The driver is always responsible for braking
at the correct time. Do not let the increased
safety provided tempt you into taking risks .
This could increase your risk of a collis ion.
- The system can deploy incorrectly due to
system-specific limits.
- Please note that the sensors and the camera
do not always detect all objects or lane
markings . This increases the risk of an acci­
dent.
- Pre sense front does not react to people, an­
imals or objects that are crossing the vehi­
cle 's path or that are difficult to detect

in General information on page 97.
-Reflective objects such as guard rails or the
entrance to a tunnel, heavy rain and ice can
affect the function of the radar sensors and
the system's ability to detect a collision risk.
(D Note
The sensors can be displaced by impacts or
damage to the bumper, wheel housing and
underbody. Pre sense front can be impaired
by this. Have an authorized Audi dealer or au­
thorized Audi Service Facility check their func­
tion.
(D Tips
- You can cancel the braking with increasing
force that is initiated by the system by brak­
ing yourself, by accelerating noticeably or
by swerving.
- Keep in mind that pre sense front can brake
unexpectedly. Always secure any cargo or
objects that you are transporting to reduce
the risk of damage or injury.
- Certain pre sense front functions are switch­
ed off when the ESC is limited or switched
off
