BRAKE/ This warning/indicator light illuminates when
the brake fluid level is too low or when there
is a malfunction in the ABS, or when the park ­
ing brake is set.
If the - (USA models)/ . (Canada
models) symbol flashes in the disp lay with the
parking brake released, there is a ma lfuncti on
in the brake system . In addition to the sym­
bol, one of two messages appears in the dis­
play:
Stop vehicle and check brake fluid level
Stabilisation program and ABS fault! See
Owner's manual
.. Pull off the road and stop the vehicle.
.. Obtain professional ass istance.
USA models: if there is a malfunction in the
ABS system, the

The light - (USA)/ . (Canada) illumi­
nates when the ign ition is turned on . It goes
out after the engine has been started and the
parking brake is fu lly released . This indicates that the brake
warning light is functioning
properly.
If the brake warning light does not light up
when the engine is cranking or the parking
brake is applied, there may be a malfunction
in the electrical system. In this case, contact
your Audi deale r.

before opening the en­
gine hood and checking the brake fluid.
- Driving with low brake fluid is a safety
hazard! Stop the car and get profess ional
assistance.
- USA models:: If both, the 1111 warning
light and
the m warning light come
on at the same time, the rear wheels
could lock up first under hard braking.
Lock-up of the rear wheel brakes can
cause loss of vehicle cont rol and an acci­
dent. Have your vehicle repaired

slowly and avoid sudden, hard brake ap­ plicat ion.
- Canada models: If both, the brake warn­
ing light . and the ABS warning light
Ii] come on at the same t ime, the rear
wheels could lock up first under hard braking. Lock-up of the rear wheel brakes
can cause loss of vehicle control and an
acc ident. Have you r vehicle repaired im­
med iately by your authorized Audi dealer
or a q ualified workshop. Drive slowly and
avoid sudden, hard brake application
- If the brake warning/indicator light does not go out after a few seconds and the
park ing brake re leased, or lights up while
you are driving, the fluid level in the brake flu id reservo ir is too low. If you be­
lieve that it is safe to do so, proceed im­
med iately at low speed to the nearest
authorized Audi dealer o r qualified work­
shop and have the bra ke system inspect­
ed.
- Always keep in m ind that afte r several
brake applicat ions, yo u will need g reater
pressure on the b rake peda l to s top your
vehicle. Do no t re ly on stra ined brakes to
respond with maxim um stopping power
in critical situations . You must allow for
increased brak ing distances. The extra
distance used up by fad ing brakes could
lead to an acc ident.
~ / ! .!r Safety systems
The I (USA models)/ . (Canada mode ls) in­
d icator light monitors the safety systems e.g.
a ir bags, pretensioners a nd illum inates for a
few seconds each time you switc h the ign ition
on.
If the
I (USA models)/ . (Canada models)
indicator light does not go out, or if it illumi­
nates w hile you are driv ing, or if it sta rts to
b link , then there is a ma lf u nction somewhere
in the system. If the light does not illuminate
when you switch on the ignition, this also
means there is a ma lfunction.
A WARNING
If you have a ma lfunction in the safety sys­
tems, contact your authorized Audi dea ler
i mmediately. Othe rwise the safety sys­
tems may not work properly in an acc i­
dent.

Notice about data
recorded by vehicle
control modules
Your veh icle is not equipped with an Event Da­
ta Recorder (EDR), installed by some manu­
facture rs fo r the express p urpose o f capturing
data for retrieval after an accident or cras h
event. EDR's are sometimes called "crash re­
corders".
Some state laws res trict the retrieval or down­
loading of data stored by EDR's that were in­
stalled in a vehicle for the express purpose of retrieving data after an accident or crash
event without the owner's consent.
A lthough yo ur vehicle is not equ ipped wit h an
EDR, it is equipped with a number of elect ron­
ic control modules for various vehicle systems
such as, for examp le, eng ine function, emis­
sion control, as well as for the airbags and
safety belts.
These electron ic control modules also record
vehicle-re lated data during norma l vehicle op­
eration for diagnostic and repa ir purposes.
The recording capacity of the electronic con­
trol modules is limited to data (no sound is re­
corded) and only a small amount of data is ac­
tually recorded ove r a ve ry limited pe riod of
time and stored when a sys tem fault or other
condition is sensed by a cont ro l u nit. Some of
the data then stored may re late to vehicle
speed, direction, braking as we ll as restraint
system use and performance in the event of a
crash or other condition. Stored data can only be read and downloaded w ith special equip­
ment .
Electronic Stability
Control (ESC)
The Electronic Stability Control increases driv­
ing stability.
F ig . 1 31 Center console with~ button
Intent and purpose
The Anti-Lock B ra ke System (ABS), Elec tronic
Differential Lo ck (EDL) and Anti-Slip Regula­
tion System (ASR) are integrated i n the Elec­
tronic Stability Control (ESC). It increases con­
tro l over the vehicle in handling conditions
close to the limit of "grip", such as when ac­
celerating and corner ing. It reduces the risk of
skidding under all road condit ions and at all
speeds and improves veh icle stability. When
road cond itions are poor, ESC makes it easier
to sta rt from a comp lete s top as we ll as accel­
era te and drive up hills. ESC sw itches on auto­
matically when yo u start the engine . It should
norma lly be activated at all times because this
ensures optimum vehicle stability .
Critical driving situations
With an overs teering vehicle ( the vehicle
tu rns too s harply and the rear wheels slide to­
ward the o utsi de of a curve), ESC primarily
brakes the outside front wheel, with an
un­
dersteering vehicle (the vehicle does not turn
sharp ly enough and pushes out of a curve) it
brakes the inside rear whee l or other addition­
al wheels. This brake inte rvent ion is accompa­
nied by noises.
If the speed of a wheel s lows down too much
relat ive to vehicle speed while braking and it
starts to lock, brake pressure to this whee l is
reduced . This adjustment process can be felt ..,.

as a pulsing mo tio n of the brake pe dal, ac­
companied by some noises. I n order for ABS
to be a ble to operate optimally in th is range,
you must keep the brake pedal depressed -
never "pump the brakes" . You should not ex­
pect that braking d is tances w ill be
shortened
under all circumstances w ith ABS . Braking dis­
tance may even be slightly
longer , for exam­
p le on gravel or wi th fresh snow on a slippery
surface .
If a sign ificant
speed differential between the
d rive w heels on one axle is determined (for
examp le, on a su rface that is s lippery
on one
side),
t he EDS brakes the spinn ing whee l and
transfers power to the other drive whee ls.
This is done up to a speed of about 60 mph (100 km/h) . Noises from the brake system
signal that whee l spin is being controlled.
I f one wheel spins when s tarting from a com­
p lete stop because o f a different grip (for ex ­
ample , one wheel o n ice), keep your foot
hard
on the acce lerator until the veh icle starts to
move.
If the wheels spin , ASR wi ll automatically re­
duce engine torque and match power to road
su rface condit ions .
Switching on Sport mode
In specific drivi ng situa tions (e.g. La unch Con ­
trol), you switch ASR and ESC to Sport mode
by pressing the
[!I button once . The indicator
light
11 illuminates and ESP sport -Warning!
Restricted stability
appears . "Slip" is matched
to the speed. You should do this only if your
driving skill a nd traffic cond it ions permit .
Switching ASR /ESC off
In certain sit uat ions (e .g . in deep snow, on a
l oose surface, o r when rocking the vehicle
free), switch ASR and ESC off by pressing the
[ill button for more than 3 seconds. The ind ica­
tor light
II i lluminates and E SP swit ched off -
Warning! Re stricted stability appea rs . You
should do th is only if your driving skill and
traffic cond it io ns pe rmit .
Int ellig ent technolog y 143
Switching ASR /ESC on
Activate ASR/ ESC by pre ssing the [!I bu tton
again. The message
ESP on appears in the dis­
play briefly.
Brake overheating
So that the disc b rake on a b raked wheel does
not over heat, the EDS switche s off au toma ti­
ca lly if there is un usua lly severe loa ding a t
th is wheel. The vehicle is st ill drivable and has
the same properties as a vehicle without EDS .
As soon as the brake has coo le d down, EDS
swi tches on aga in automatically .
A WARNING
- Even ESC, ABS, EDS and AS R cannot over ­
come the laws of physics . You should
keep t his in m ind in particular on an icy
or wet road. If the systems intervene,
you shou ld ad just your speed immediate­
ly to road and traff ic conditions . Do not
be tempted by the increased safety pro­
vided to take risks -you risk having an
accide nt.
- Please keep in mind that the risk of an
accident is i ncreased by d riving too fast,
pa rti cularly in corners and on icy or wet
ro ads, and by drivi ng too close to the ve­
hicle ahead . Even ESC, ABS, E DS and A SR
cannot eliminate the increased risk of
having an accident.
-Apply the throttle ca re fully when accel ­
erating on a consistently s lippery sur­
face, e .g. on ice and snow . The drive
wheels can spin in spite of the EDS and thereby affect vehicle stability -you risk
having an accide nt.
- Please note that when ASR or ESC/ASR is
deactivated , the drive wheels can spin on
icy and sl ippery roads a nd the veh icle can
break away -the re is a risk of skidd ing!
(D Tips
- In the event of a defect in the rear spoil-
er system or in Audi magnet ic ride, it can
happen that ASR and ASR/ESC cannot be .,.

Braking
New brake pads
During the first 250 miles (400 km), new
b rake pads do not possess their full braking
effect, they have to be "broken in" first. The
distance can be ten times longer in veh icles
with ceramic brakes*. You can compensate for
this slightly reduced brak ing power by push­
ing harder on the brake pedal. Avoid heavy
braking loads during the break-in period.
Operating conditions and driving habits
The brakes on today's automobi les are sti ll
subject to wear, depending largely on operat­
ing conditions and dr iv ing habits
c:> & . On ve­
hicles that are either driven mostly in stop­
and-go city traffic or a re driven hard, the
brake pads should be checked by your author­
ized Audi dealer more often than specified in
the
Warranty & Maintenan ce booklet . Failure
to have your b rake pads inspected can result
in reduced brake performance.
On steep slopes, you shou ld use the brak ing
effect of the engine. This way, you prevent un­
necessary wear on the brake system . If you
must use your brakes, do not hold the brakes
down continuously. Pump the brakes at inter­
va ls.
Moisture or road salt
Under ce rta in conditions, for example, when
d riving through water or very heavy rain, or
even after washing your vehicle, the braking
effect can be reduced due to moisture (or in
freezing conditions ice) on the brake pads. A
few cautious brake applicat ions should dry
off
the brake pads or remove any ice coatings.
When you are driving at higher speeds with
the windshield wipers on, the brake pads will
briefly touch the brake d iscs in regular inter­
vals so as to improve reaction t ime when brak­
ing on wet surfaces. You, the driver, will not
notice anything.
The effectiveness of the brakes can be reduced
when the vehicle is dr iven on a salt-covered
road and the brakes are not used . Likewise,

you clean off accumulated salt coating from
brake discs and pads with a few cautious ap­
plications of the brake

Corrosion
The re may be a tendency for dirt to build up
on the brake pads and corros ion to form on
the discs if the car is not driven regularly or
on ly for short trips with litt le use of the
brakes.
If the brakes are not used frequently, o r if cor­
rosion has formed on the discs, it is advisable
to clean
off the pads and discs by braking
firmly a few times from a moderately high
speed

Faults in the brake system
If you shou ld notice a sudden increase in
brake pedal travel, then one of the two brake
circuits may have fai led . Drive immediately to
the nearest qualified workshop to have the
damage repaired. Drive at reduced speed on
the way there and anticipate longer stopping
distances and higher pedal pressure c:> &,.
Low brake fluid level
Malfunctions can occur in the brake system if
the brake fluid level is too low. The brake flu id
level is monitored electronically.
Brake power assist unit
T he brake power assist unit increases the
pressure that you generate with the brake
pedal. It works only when the engine is run­
ning.
Brake lining wear status
Brake lining wear may be checked by visual in­
spection of t he condition of the brake pads
thro ugh the openings in the wheel. If neces­
sary, the whee l may be removed for this in­
spection

A WARNING
--You should perform braking maneuvers
for the purpose of cleaning the brake
system only if road conditions permit.
