Introduction
Applies to vehicles: with Audi pre sense basic or Audi pre sense front
With in the limits of the system, p re sense basic
and pre sense front can in it iate steps to protect
vehicle occupants in certain dangerous s ituaÂ
tions .
Critical driving situat ions can be recogn ized by
the pre sense front via a network of different ve hi cle systems and can take steps to prepare the
ve hicl e o ccupants for a potential collis ion.
The pre sense front works w ith a radar sensor
and a video camera*. It also functions within the limits of the system when adaptive c ruise conÂ
tro l* is switched off .

Audi pre sense basic
Description
Applies to vehicles: with Audi pre sense basic
The function of the pre sense basic is activated at
a speed of 20 mph (30 km/h) or h igher .
The following functions can be triggered under certain condit ions w ith in the lim its of the sysÂ
tem:
- Tensioning of the safety belts (for examp le,
during heavy braking): the front safety belts have reversib le be lt tens ioners. If a collision
does not occur, the safety belts loosen slightly
and are ready to tr igger aga in.
- Closing the windows and the sunroof* (for exÂ
ample when over- or understeering): the winÂ
dows close until the re is only a small gap open
and the s unroof* closes all the way .

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 iÂ
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.

If you do not react enough or not at all to a da nÂ
gerous s ituation that was detected by the sysÂ
tem , pre sense front provides assistance by apÂ
plying t he b rakes .
- If a collision is imminent, the system will first
prov ide an
acute w arning by braking sharply .
You will also be made aware of the danger by the ins trument cluste r display
c:> fig . 125. For
veh icles with adaptive cru ise cont rol, the . inÂ
dic ator light a lso tu rns on .
- If you do not react to the acute warning, pre
sense front can brake w ith increasing force
w it hi n the lim its of the system
l )_ This reduces
the vehicle speed in the event o f a collis ion . The
message

- At low driving speeds, pre sense front can begin
complete deceleration shortly before a
co llision
l).
- If p re sense front determines t hat you are not
braking strongly enough when a co llision is imÂ
m inent, it can increase the braking force.
A WARNING
-
- Pre sense front cannot overcome natura l
phys ica l laws. It is a system designed to as Â
sist and it cannot prevent a collision . The
driver m ust always intervene . The dr iver is
always responsible fo r braki ng at the correct

detect all objects. This increases the risk of
a collision.
- Pre sense front does not react to people or
animals or objects that are crossing the veÂ
hicle's path or are difficult to detect
¢ page 133.
-Reflective objects such as guard rails or the
entrance to a tunnel, heavy rain and ice can
affect the function of the radar sensor and
the system's ability to detect a collision risk.
- Lack of attention can lead to collisions, othÂ
er accidents and serious injuries. pre sense
front is an assistance system and cannot
prevent a collision by itself. The driver must
always intervene. The driver is always reÂ
sponsible for braking at the right time.
- Always pay attention to traffic, even when
pre sense front is switched on. Always be
ready to intervene and take over complete
control of the vehicle whenever it is necesÂ
sary. Always follow traffic laws regarding
maintaining a safe distance between your
vehicle and vehicles ahead.
- pre sense front works within certain limits
and cannot react to situations that are outÂ
side of the system limits, such as when apÂ
proaching a stationary vehicle or a stationÂ
ary obstacle (the end of a traffic jam or aveÂ
hicle that has broken down).
- Always keep in mind that the radar sensor
for pre sense front only works within deÂ
fined detection zones, which means other
vehicles may not always be detected corÂ
rectly.
- The function and range of the radar sensor
can be impaired by rain, snow and heavy
mist. Vehicles ahead may not be detected
right away, or not detected at all.
- Reflective surfaces such as guard rails or enÂ
trances to tunnels may impair the function
of the radar sensor.
(D Note
The sensor can be disp laced by impacts or
damage to the bumper, wheel housing and
underbody. Pre sense front can be impaired
by this. Have an authorized Audi dea ler or au-
Assist
thorized Audi Service Facility check their funcÂ

(D Tips
- You can cancel the bra king with increas ing
force that is initiated by the system by brakÂ
ing yourself, by acce lerating noticeably or
by swerving.
- For information on driver messages about
pre sense, refer to¢
page 142.
- 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.

Notice about data
recorded by the Event
Data Recorder and
vehicle control modules
Event Data Re corder
This vehicle is equipped wi th an Event Data Re Â
corder (EDR) . The main purpose of an E DR is to
record, in certain crash or near crash -like situaÂ
tions, such as an airbag deploym ent or h itting a
road obstacle, data that will assist in understandÂ
ing how a veh icle 's systems performed . The EDR
is designed to record data related to veh icle dyÂ
namics a nd safety systems for a sho rt period of
time, typically 30 seconds or less . The E DR in this
veh icle is designed to reco rd s uch data as :
- How various systems in your vehicle were operÂ
at ing;
- Whether or not the driver and passenger safety
belts were buckled/fastened;
- How far ( if at all) the driver was depressing the
acce lerator and/or brake peda l; and,
- How fast the ve hicle was trave ling.
These data can help provide a better understand ing of the ci rc u mstances in which c rashes and in Â
juries occur. NOT E: EDR data are recorded by yo ur
veh icle only if a non-trivia l crash situat ion occurs;
no data are recorded by the EDR under normal
driving conditions and no personal data (e .g .,
name, gender, age, and crash location) a re reÂ
corded . H owever , other pa rties , such as law enÂ
forcement, cou ld combine the EDR data w it h the
type o f person ally identifyi ng dat a routine ly acÂ
qu ired dur ing a crash invest igat ion .
To read data reco rded by an EDR, specia l equipÂ
men t is req uire d, and access to the veh icle or the
E DR is needed. In ad dition to the vehicle manuÂ
facturer, other parties, s uch a s law enforcement,
that have t he specia l equipment, can read the inÂ
formation if they have access to the vehicle or the E DR.
Some s tate laws restrict the re trieva l or downÂ
loading of data stored by ED Rs insta lled in a vehi Â
cle fo r the express purpose of retrieving data af -
158
ter an accident or crash event withou t the own Â
er 's consent.
Audi will not access the EDR and /or sim ilar data
o r g ive it to others -
- unless t he ve hicle ow ner (o r lessee if the vehiÂ
cle has been leased) ag rees; o r
- upon the offic ial request by the police; or
- upon the order of a court of law or a govern-
ment agency; or
- for the defense of a lawsuit through the jud icia l
discovery process.
- Audi may also use the data for research about
veh icle operation and safety perfo rmance or
prov ide the data to a th ird party for research
purposes w itho ut identify ing t he specific vehiÂ

Electronic stabilization
control (ESC)
Description
Electronic Stabilization Control (ESC) supports
driver safety. It reduces the risk of slipping and
improves dr iving stability. ESC detects crit ical sitÂ
uations suc h as the vehicle overstee ring and unÂ
de rs teer ing or the wheels are sp inning. The vehiÂ
cle is s tabilized by app ly ing the brakes or reducÂ
i ng e ngine torque. Once t he ES C i s ac tiva ted, the
indicator light
DJ b li nks in the instrument clus Â
ter .
The fol low ing systems are integrated in the ESC:
Anti-lock braking system (ABS)
ABS preve nts the whee ls from lock ing whe n brakÂ
i ng. The vehicle can s till be steered even during
h a rd brak ing. Apply steady press ure to the brake
pedal. Do not pump the pedal. A puls ing in t he
bra ke pedal indica tes th at the system is act ing to
s tabili ze the vehicle.
Brake assist system
The brake assist sys tem can decrease braking disÂ
tance .
It increases brak ing power when the d rive r
p resses the brake pedal q uic kl y in eme rgency sitÂ
uations. Yo u m ust press and hold the b rake pedal
u nti l the dangero us si tuati on is over. In ve hicles
with adaptive cruise contro l*, the bra ke assist
system is more sensitive if the d istance detected
to the veh icle ahead is too small.
Anti-slip regulation (ASR)
ASR red uces eng ine power when the drive wheels
begin spinning an d adapts the force to the road
conditions. This makes it easie r to sta rt, acceler Â
ate and drive up inclines .
Intelligent Technology
Electronic differential lock (EDL)
T he ED L brakes wheels t hat are spi nning and
transfe rs the drive power to the o ther dr ive
whee l or wheels if the vehicle is equ ipped with all
whee l drive *). T his function is not available at
higher speeds.
In extreme cases, ED L automat ica lly swi tches off
to keep the b rake o n the braked whee l from overÂ
heating. The vehicle is still working correct ly. ED L
will switc h on again automatically when condiÂ
tions have returned to normal.
Steering recommendation
T he ESC he lps to s tabilize the vehicle by changing
the steering torque.
Selective wheel torque control
Se lective w heel torque con trol is used w hen d riv Â
i ng on curves. The front whee l on the ins ide of
the curve or both wheels on t he i nsid e of the
c ur ve are braked se lective ly as needed . This al Â
lows more precise driving in c urves .
Automatic post -collision braking system
T he "Automat ic pos t-collis ion braki ng system"
ca n help to reduce the ris k of sliding and of othe r
collisions af ter an a cciden t. If th e ai rbag cont rol
module detects a collision above a certai n vehicle
speed, the vehicle is brake d by the ESC.
T he veh icle does not br ake au tomatic ally if:
- the dr iver presses the acce lera tor pedal, or
- the braking fo rce generated by the pressed
brake pedal is greater than the b raking force
that would be in itiated by the system, or
- the ESC, the brake system o r the veh icle electriÂ
cal system are not functioning.
A WARNING
- T he ESC and its i nteg rated systems ca nnot
over come the li mits posed by natu ral physiÂ
cal laws. This is espe cially impor tant on slipÂ
pery o r we t roads . If the systems beg in actÂ
ing to stabilize your veh icle, you should im Â
mediately a lter your speed to match the
road and tra ffic condit ions. Do not let the
increased safety provided tempt you into
