Audi pre sense
Preventative passenger
protection
A pp lies to veh icles: with Audi pre se nse
Audi pre sense can initiate steps to help pro
tect vehicle occupants in certain situations.
The functions described depend on equ ipment
installed in your vehicle:
Audi pre sense basic*
The following functions can be triggered in
certain driving situations:
- Tightening of the safety belts (for example,
during heavy braking) : the front safety belts
have reversible belt pretensioners. If a colli
sion does not occur, the safety belts loosen
slightly and are ready to be tightened again.
- Closing the windows and the sunroof*: the
windows and the sunroof* close leaving a
small open gap.
Audi pre sense basic functions can be trig
gered at speeds above 20 mph (30 km/h).
Vehicles with Aud i drive select*: the deploy
ment time is adapted in
Dynamic mode.
Audi pre sense front (vehicles with
adaptive cruise control*)
Audi pre sense front includes the functions in
Audi pre sense basic. In addition, within the
limits of the system, the likelihood of a colli
sion with the vehicle immediately ahead is al
so calculated . If the system senses an immi
nent collision the following functions can be
tr iggered :
- Braking guard c::>poge
87
-Tightening the safety be lts
- Closing the windows and the sunroof* (leav -
ing a small open gap)
Audi pre sense rear (vehicles with Audi
side assist*)
Audi pre sense rear includes the functions in
Audi pre sense basic. In addition, the likeli
hood of a rear-end collision with the vehicle
coming from behind is also calcu lated.
If the risk
of a co llision is detected, the following
functions can be triggered:
- Tig htening the safety belts
- Closing the windows and the sunroof* (leav-
ing a small open gap)
Audi pre sense plus*
Audi pre sense plus includes the functions in
Audi pre sense front and Audi pre sense rear.
Error message
Audi pre sense: not available
Preventative passenger protection is not avail
able. See your authorized Audi dealer immedi
ately to have the malfunction corrected.
_& WARNING
-=
Audi pre sense cannot overcome the laws
of physics. It cannot prevent a collision. Do
not let the increased safety provided
tempt you to take risks. This will increase
the r isk of a collis ion and serious personal
in juries .
- The sensors cannot always detect all ob
jects. This increases the risk of a colli
s10n.
-Aud i pre sense does not detect people or
an im als or objects that are crossing the
veh icle's path c::> page
81.
-The radar sensor's vis ion can be reduced
by heavy rain, ice, snow, heavy road sp ray
and reflections from guard rails, tunnel
entrances, etc. These and similar condi
tions can prevent vehicles from being ac
curately detected and in some cases they
may not be detected at all.
(D Note
The sensors can be displaced by impacts or
damage to the bumper, wheel housing and
underbody. This can affect the function of
the Audi pre sense system. Have your au
thorized Audi dealer check to make sure
that the system is working properly.

Notice about data
recorded by the Event
Data Recorder and
vehicle control modules
E ve nt Dat a Recorder
This vehicle is equipped with an Event Data
Recorder (EDR) . The main purpose of an EDR
is to record, in certain crash or near crash-like
situations, such as an airbag deployment or h itting a road obstacle, data that will ass ist in
understand ing how a veh icle's systems per
formed. The EDR is designed to record data
re lated to vehicle dynamics and safety sys
tems for a short period of time, typically
30 seconds or less. The EDR in this vehicle is
designed to record such data as:
- How various systems in you r vehicle were
operating;
- Whether or not the d river a nd passenger
safety belts were buckled/fastened;
- How far ( if at all) the dr iver was dep ress ing
the accelerator and/or brake peda l; and,
- How fast the ve hicle was traveling.
These data can help provide a better under
stand ing of the c ircumstances in which crash
es and injuries occur . NOTE : EDR data a re re
corded by your veh icle only if a non-trivial
crash sit uat ion occ urs; no data are recorded by
the EDR under normal driving cond itions and
no personal data (e.g., name, gender, age,
and crash location) are recorded. However,
other parties, such as law enforcement, co uld
comb ine the EDR data with the type of per
sonally identify ing data routinely acquired
during a crash invest igation .
To read data recorded by an EDR, special
equ ipment is required, and access to the veh i
cle or the EDR is needed. In add ition to the ve
h icle manufacturer, other parties, such as law
e nfo rcement, that have the special equip
ment, can read the information if they have
access to the ve hicl e or the EDR. Some state
laws restrict the retrieval o r down
loading of data stored by ED Rs insta lled in a
vehicle for the express purpose of retrieving data after an accident or crash event w ithout
the owner's consent .
Audi will not access the EDR and/or simi lar
data or g ive it to others -
- un less the vehi cle owner (or lessee if the ve
hicle has been leased) agrees; or
- upon the officia l request by the police ; or
- upon the o rder of a court of law or a govern-
ment agency; or
- for the defense of a lawsuit through the ju
dicia l discovery p rocess.
- Aud i may also use the data for research
about vehicle ope rat ion and safety perform
ance or provide the da ta to a third party fo r
research purposes without iden tif ying the
specif ic vehicle or in formation about the
identity of its owner or lessee and only after
the recorded vehicle data has been ac
cessed .
Vehicle control modul es
Your vehicle is also equ ipped with a n umber of
electron ic control modules for various vehicle
systems, such as engine management, emis
sion contro l, airbags, and safety belts.
T hese electronic con trol mod ules record data
during norma l vehicle operation that may be
needed by trained technicians for diagnostic
and repair purposes. The recording capability
of these modu les is limited to data (no sound
is recorded). Only a small amount of data is
actually recorded over a very lim ited period of
t ime, or stored when a system fault is detect
ed by a contro l modu le. Some of the data
stored may re late to vehicle speed, direction,
o r braking, as well as restraint system use and
performance in the event of a crash. Stored
data can also only be read and dow nloaded
with special eq uipment that is directly con-
nected to the vehicle. .,..

Electronic Stabilization
Control (ESC)
Description
ESC helps to improve road holding and vehicle
dynamics to help reduce the probability of
skidd ing and loss of veh icle control. It works
only when the eng ine is running. ESC detects
certain difficult driv ing s ituations, including
when the vehicle is beginning to spin (yaw)
out of cont ro l and helps you to get the vehicle
back under control by select ively brak ing the
wheels, and/or red ucing engine powe r and
p roviding steering assistance to help hold the
ve hicle on the driver's intended course . The in
dicator light
m in the instrument cluster
blinks when ESC is taking action to help you
control the vehicle.
ESC has limitations.
It is important to remem
ber that ESC cannot overcome the laws of
phys ics. It will not a lways be able to help out
under all conditions you may come up against.
For example, ESC may not always be able to
h elp you master situat ions where there is a
sudden change in the coefficient of fr iction of
the road surface. When there is a sect io n of
d ry road that is s udden ly cove red with water,
slush o r snow, ESC canno t perform the same
way it would on the dry su rface.
If the vehicle
hydroplanes (rides on a c ush ion of wate r in
stead of the road surface), ESC wi ll not be
ab le to he lp you steer the veh icle because con-
Int ellig ent technolog y 187
tact with the pavement has been interrupted
and the vehicle cannot be braked or steered .
D uring fast corner ing, particular ly on wind ing
roads, ESC cannot always deal as effectively
with difficult dr iv ing s ituations than at lower
speeds.
A lways adjust your speed and driving style to
road, traffic and weather condit ions. ESC can
not override the vehicle's physical lim its, in
crease the availab le tract ion, or keep a veh icle
o n the road if road departu re is a result of
drive r inattent io n. Instead, ESC imp roves the
poss ibility of keep ing the vehicle unde r con
trol and on the road dur ing extreme maneu
vers by using the driver's steering inp uts to
help keep the vehicle going in the intended di
rection . If you are traveling at a speed that
causes you to run off the road before ESC can
provide any assistance, you may not experi
ence the benefits of ESC.
ESC is switc hed on all the time . In certain sit
uat ions when you need less traction, yo u can
switch off ASR by pressing the button
[&I
c::> page 189, fig. 180. Be sure to switch ASR
o n again when you no longer need less t rac
t ion.
The following systems are integrated in the
ESC:
Anti-lock bra king sy stem (ABS )
ABS prevents the whee ls from locking up
whe n brak ing. The vehicle can sti ll be stee red
even dur ing hard braking. App ly steady pres
s u re to the brake pedal. Do not pump the ped
al. A pulsing in the brake pedal indicates that
the system is helping you to brake the vehicle.
Brake as sist sy stem
The brake assist system can decrease braking
distance. It increases brak ing power when the
driver presses the brake peda l quickly in emer
gency s ituations. You must press and hold the
brake pedal until the situation is over. In
vehicles with adapt ive c ruise control*, the
brake assist system is more sensitive if the
distance detected to the vehicle ahead is too
small.

188 Intelligent technology
Anti-slip regulation (ASR )
ASR reduces engine power when the drive
wheels begin to spin and adapts the force to
the road conditions. This makes it easier to
start, accelerat e and drive up hills .
Electronic differential lock (EDL )
The ED L brakes wheels that are spinn ing and
transfers the drive powe r to the o ther wheels.
This function is not availab le at higher speeds.
I n extreme cases , ED L automat ica lly switches
off to help keep the brake on the braked whee l
from ove rheating. EDL wi ll sw itch on aga in au
tomatically when conditions have returned to
norma l.
Steering recommendation
The ESC helps to stabilize the ve hicle by
changing the steering to rque.
In vehicles with dynam ic steering*, ESC also
he lps to stabilize the stee ring in critical s itua
tions.
Selective wheel torque control
Selective wheel torque control is used when
driving on curves . The front wheel on the in
side of the curve o r both wheels on the inside
of the curve are braked selective ly as needed.
This a llows more prec ise driving in curves. The
appl icable system may no t activ ate when driv
ing in wet or snowy condi tions .
A WARNING
- The ESC and its integrated systems can
not overcome the lim its posed by natural
physical laws. This is especia lly impor- tant on slippery or wet roads
. If the sys
tems beg in acting to stabilize your vehi
cle, you should immediately change your
speed to match the road and traffic con
ditions . Do not let the increased safety
provided by these systems tempt you to
take risks. Do ing so will increase the risk
of a loss of veh icle contro l, collision and
serio us pe rsonal inj uries.
- Always ad apt your speed to road, traffic
a nd wea ther conditions. The risk of los
ing con trol of the vehicle increases when
driving too fast, especially through
curves and on slippe ry or wet roads, and
when dr iv ing too close to vehicles up
ahead . The ESC and its integrated sys
tems cannot a lways prevent collisions -
there is still a risk of acc idents!
- Always accelerate with special care on
even, smooth su rfaces such as those that
are wet or covered with ice and snow.
The drive wheels can spin even w ith
these assistan ce sys tems that cannot al
ways he lp to re duce the risk of loss of ve
h icle control.
(D Tips
- ABS and ASR o nly wo rk correctly when
all four wheel s are equipped with identi
c al tires . D iffe ren t tire sizes can lead to a
reduction in engine power.
- Yo u may hear noises when the systems
descr ibed are working.
- If the ind icator lig ht
BJ or rJlll (USA

Indicator lights
I)/. Rear spoiler: system malfunction!
The rear spoiler may not have extended due to
a malfunction. This could change the vehicle's
driving characteristics at high speeds. Do not
exceed 85 mph (140 km/h). Drive to your au
thorized Audi dealer immed iately to have the
malfunction corrected . The co lor of the indica
tor light depends on the veh icle speed.
A WARNING
-Driving at higher speeds without the rear
spoiler deployed can impair handling char
acteristics, making the vehicle harder to
control.
-Always make sure that the spo iler is de
p loyed when driving at speeds over
85 mph (140 km/h) . If the rear spoiler
warn ing/ indicator light in the instru
ment cluster comes on, the rear spoiler
may not have deployed.
- Never drive at speeds higher than
85 mph (140 km/h) if the spoiler is not
deployed. Have the spoiler inspected as
soon as possible by an authorized Audi
dealer or qualified workshop.
- Always obey speed limits and other traf
fic laws.
A WARNING
Improper operation of the rear spoi ler can
cause crushing injuries.
- Always make sure that nobody, especially
children, is in the way when the rear
spoiler is deployed or retracted.
(D Note
- Never push the vehicle or apply force to
the rear spoiler -it could be damaged.
- To prevent damage to the rear spo iler do
not lean or place anything on it.
- Only operate the rear spoiler manually
when the rear lid is closed and the rear
spoiler moving parts are not blocked. Otherwise, damage cou ld occur.
(D Tips
Clean the spoiler compartment every 2 to
3 months. The spoiler compartment must
always be free of ice, snow, leaves or other
debris.
