" N .... 0 0 :c ' What can the braking guard do?
When detected in time, the system can assess
dangerous sit uat ions where an object a head
brakes suddenly or if your own vehicle is traveling
at a high speed and approaching an object that is
mov ing more slowly. The brak ing guard does not
react if it cannot detect the situation.
The system advises you of various dangero us sit­
uations :
- T he
distan ce warning occurs if you d rive too
closely to the object ahead for a long period o f
time . If the object ahead brakes strongly, you
would not be able to avoid a collision .
The.
indicator light appears as an indication for th is.
- The
app roach wa rning occurs when an object
ahead is traveling more s low ly or brakes
strongly. When th is warning occurs, it may on ly
be poss ible to avoid a co llision by swerving or
braking strongly . The danger is indicated by the
• ind icator light ¢ fig . 113 . An aud io signal
will a lso sound .
If you do not react early enough or at a ll to a dan­
ge rous situation, the braking guard suppo rts you
w ith a brak ing intervent ion . T he approach warn­
i ng indicators and the message
Braking guard :
e ngaged
also appea r.
- If a co llision is imminent, the system will first
provide a n
acute warning by braking sharply .
- If you do not react to the acute warning, the
brak ing guard can increase the braking force
withi n the l imits of the system . This reduces
the vehicle speed in the event of a co llision.
- T he system can init iate complete decelerat io n

- Always remember that the radar sensor for
the brak ing guard works only within def ined
detection and range limits that may prevent
the proper detect ion of other vehicles.
- The radar sensor's function and range can
be reduced by rain, snow and heavy spray.

" N .... 0 0 :c ' Intelligent Technology Electronic Stabilization
Control (ESC)
Description
The ESC increases driving safety. It reduces the
risk of slipping and improves driving stability.
ESC detects critical situations such as when the
vehicle is oversteering and understeering or the
wheels are spinning. The vehicle is stabilized by
applying the brakes or reducing engine torque .
When the ESC engages,
the G1 indicator light
b links in the instrument cluster.
The following systems are integrated in the ESC:
Anti-lock braking system (ABS)
ABS prevents the whee ls from locking when brak­
ing. The vehicle can still be steered even during
hard braking. Apply steady pressure to the brake
pedal. Do not pump the pedal. A pulsing in the
brake pedal indicates that the system is acting to
stabilize the vehicle .
Brake assist system
The brake assist system can decrease braking dis­
tance. It increases braking power when the driver
presses the brake pedal quickly in emergency sit­
uations . You must press and hold the brake pedal
until the dangerous situat ion is over . In veh icles
w ith adaptive cruise contro l*, the brake assist
system is more sensitive if the distance detected
to the vehicle dr iv in g ahead is too small. On
ve hicl es w ith activated and functioning night vi­
sion assist*, the brake assist system can respond
more sensitively if there is a warning .
Anti-Slip Regulation (ASR)
ASR reduces engine power when the drive wheels
begin spinning and adapts the force to the road
conditions. This makes it easier to start, acceler­
ate and drive up hills.
Electronic differential lock (EDL)
EDL applies the brakes to a wheel that starts
sp inn ing and transfers the drive power to the
other driving wheels. This functio n is not availa­
ble at higher speeds.
Intelligent Technology
In extreme cases, EDL automatica lly switches off
to keep the brake on the braked whee l from over ­
heating. The vehicle is still working correct ly. ED L
will switch on again automatically when condi­
tions have returned to normal.
Steering recommendation
T he ESC he lp s to stabilize the vehicle by changing
the steering torque .
In veh icles with dynamic steer ing*, ESC also
helps to stab ilize the steer ing in crit ica l situa­
tions.
Selective wheel torque control
Selective wheel torque control is used when driv­
in g on curves.
The front wheel on the inside of the curve or both
wheels on the inside of the curve are braked se­
lectively as needed. This allows more precise driv­
in g in curves . The applicable system may not acti­
vate when dr iv in g in wet or snowy conditions .
Automatic post -collision braking system
Th e "automat ic post-collis ion braking system"
can help to reduce the risk of sliding and of addi­
t iona l co llisions after an acc ident. If the airbag
control module detects a co llision above a certa in
vehicle speed, the veh icle is braked by the ESC.
The vehicle does not brake automatically if :
- the dr iver presses the acce lerator pedal, or
- the braking force generated by the pressed
brake pedal is greater than the braking force
that would be initiated by the system, or
- the ESC, the brake system or the vehicle electri ­
cal system are not functioning.
A WARNING
,--
- The ESC and its integrated systems cannot
overcome the lim its imposed by natural
p hys ical laws. This is especially important
on slippery or wet roads. If the systems be­
g in acting to stabilize your vehicle, you
should immediately alter your speed to
match the road and traffic conditions. Do
not let the increased safety provided tempt

" N .... 0 0 :c ' Brakes
New brake pads
New brake pads do no t ac hieve t heir f ull b raking
effect during the firs t 25 0 mi (4 00 km). They
must be "b roken
in" fi rst . The b rea k-in per io d can
be considerably longe r for vehicles with ce ram ic
brake roto rs*. However, yo u can compensate for
the slightly reduced br aking fo rce by p ressing
firm ly on the brake pedal. Avo id heavy braking
d uring the brea k-in period .
Wear
Brake pad wear depends largely on the way the
ve hicle is driven and on operat ing cond itions.
This is especially true if you are driving frequently
i n the c ity and on curves o r with a sporty driving
style .
Operating noise
Noises may occur when bra king depend ing on the
speed, braking force and outs ide cond itions s uch
as temperature and humidity .
Noises may become more appare nt at lowe r
speeds d ue to the nature of the mater ia ls in the
ceramic brake rotors*.
Effect of water and road salt
I n ce rtain s it u at ions, for ex ample a fter dr iving
throu gh water, in heavy ra in, afte r overnig ht con ­
densat io n or after washing your car, the bra king
effect can be red uced by moisture or ice on the
brake rotors and b ra ke pads. The brakes must be
"dr ied" fi rst w it h a few careful brake applica­
tions .
At highe r speeds and with the windsh ie ld w ipers
turned on, the brake pads press aga inst the brake
rotors for a sho rt amount of time. T his action,
which is not felt by the d rive r, happens a t regular
in te rvals a nd ens ures a bette r reac tion time fo r
the bra kes in wet weat her.
The braking ef fect can also be reduced if you are
d riving on salted roads and you do not apply t he
b rakes fo r long pe riods of time . The laye r of sa lt
on the br ake ro to rs and pads must be wo rn off
fi rs t when the br akes are app lied.
Intelligent Technology
Du e to its s urface, the ceram ic b rake rotor * ab ­
sorbs moistu re in ce rtain s ituations. The refore,

Corrosion
L eaving t he vehi cle pa rked fo r lo ng p eriods o f
time, low mileage and avoidin g heavy b raking
can contrib ute to corros ion on the b rake roto rs
and to dirty brake pads.
If you usu a lly avoid heavy bra king or if the re is
cor rosion prese nt, occasiona l heavy bra king at
high speeds is recommended to clean the b ra ke
r oto rs and pads
c:> ,& .
Brake system malfunction
If
you notice that the br ake pe dal trave l has sud ­
denly in crease d, then a brake circuit in the dua l­
c ir cuit b rake system may have malfu nctioned .
Drive to an authorized A udi dealer or autho rized
Audi Se rvice Facility immed iate ly to have the
prob lem cor rected . On the way there, drive w ith
red uced speed and kee p in mind that you will
need a longer dis tance to stop an d you will need
to press the bra ke pe dal harder.
Low brake fluid level
When the bra ke fluid level is low, malfu nctions in
the b rake system may occur . T he b rake fl uid level

Intellig ent T echn olo gy
- New brake pads do not achieve their full
braking effect during the first 250 mi
(400 km). They must be "broken in" first.
However, you can compensate for the
sl ightly reduced brak ing force by pressing
firmly on the brake pedal. Avoid heavy brak­
i ng dur ing t he break- in per iod.
- Certa in weather and operat ing cond it ions
such as dr iv ing through water, driving in
heavy ra in or driving after washing your ve ­
hicle can impair the effectiveness of the
brakes . In the winter, ice may build up on
the brake pads, rotors and drums . Check
these components by braking carefu lly. Ap­
plying the brakes carefully severa l times
dr ies the brakes and removes ice bu ild-up.
- The effic iency of the brakes can also be im­
paired by driving for long stretches on roads
covered w ith salt w ithout using the brakes.
You can remove salt deposits from the brake rotors and pads by carefully applying
the b rakes severa l t imes .
- If the front spo iler is damaged or you install
another spoiler, make sure the front wheel
bra kes are vent ilated properly. Otherwise,
the brake system could ove rheat, w hich re ­
duces the ir effectiveness.
- Failure of a b rake circuit impa irs b raking
perfo rmance, which inc reases brak ing dis ­
tance . Avoid driving the vehicle and have it
towed it to the nearest authorized Audi
dealer or authorized Audi Service Facility .
- If the brake booster is not working, you will
have to press m uch harder on the brake
peda l to compensate for the lack of the
booster.
@ Note
- Never let the brakes " rub" by pressing the
pedal light ly when braking is not actually
necessary. This causes the brakes to over­
heat and increases braking distance and
causes wear.
- Before driving downhill a long distance on a
steep hill, decrease your speed and select a l ower gear. This makes use of the engine
braking effect and relieves the brakes. If
130
you need to brake add itiona lly, brake in in­
terva ls and not continuous ly .
(D Tips
- If the bra ke boos ter is not wor king, you
must press the brake peda l with much more
force than normal.
- If you retrof it your vehicle with a front spoi l­
er, wheel covers or simi lar items, make sure
that the air flow to the front wheels is not interrupted. Otherwise the brake system
can become too hot.

Notice about data
recorded by the Event
Data Recorder and
vehicle control modules
Event Data Recorder
This vehicle is equipped with an Event Data Re­
corde r (EDR). The main purpose of an EDR is to
record, in certain crash or near crash-like situa ­
tions, such as an airbag deployment or hitting a
road obstacle, data that will assist in understand ­
ing how a vehicle 's systems performed. The EDR
is designed to record data re lated to vehicle dy ­
namics and safety systems 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 your vehicle were oper­
ating;
- 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 pedal; and,
- How fast the vehicle was traveling.
These data can he lp prov ide a better understand­
ing of the circumstances in which crashes and in­
ju ries occur. NOTE: EDR data are recorded by your
vehicle only if a non-trivia l crash situation occurs;
no data are recorded by the EDR under normal
driving conditions and no personal data (e.g.,
name, gender, age, and crash location) are re­
corded. However, other parties, such as law en-
Intelligent Technology
forcement, could combine the EDR data with the
type of personally identifying data routinely ac­
quired during a crash investigation.
T o read data recorded by an EDR, special equip­
ment is required, and access to the vehicle or the
EDR is needed. In addition to the vehicle manu­
facturer, other parties, such as law enforcement,
that have the special equipment, can read the in ­
formation if they have access to the vehicle or the
EDR .
Some state laws restrict the retrieval or down­
loading of data stored by ED Rs installed in a vehi­
cle for the express purpose of retrieving data af­
ter an accident or crash event without the own ­
er's consent .
Audi will not access the EDR and/or simi lar data
or give it to others -
- un less the vehicle owner (or lessee if the vehi ­
cle has been leased) agrees; or
- upon the official request by the police; or
- upon the order of a court of law o r a govern-
ment agency; or
- for the defense of a lawsuit through the judicial
discovery process.
- Aud i may also use the data for resea rch about
veh icle operation and safety performance or
provide the data to a third party for research
purposes without identifying the specific vehi­
cle or information about the identity of its own­
er or lessee and only after the recorded vehicle
data has been accessed.
Vehicle control modules
Your vehicle is also equipped with a number of
electronic control modules for various vehicle
systems, such as engine management, emission
control, airbags, and safety belts .
These electronic control modu les record data
during normal vehicle operation that may be
needed by trained technicians for diagnostic and
repair purposes. The recording capability of these
modules is limited to data (no sound is record­
ed) . Only a small amount of data is actually re­
corded over a very lim ited period of time, or stor­
ed when a system fault is detected by a control
module . Some of the data stored may relate to
