Electronic Stabilization
Control (ESC)
Description
Elect ronic Stabilization Control (ESC) suppo rts
driver safety.
It red uces the risk of slipping and
improves dr iving stability. ESC detects crit ica l sit­
uations such as the veh icle oversteering and un­
dersteering or the wheels are sp inning. The vehi­
cle is stabilized by app lying the brakes or reduc ­
ing engine torque. As soon as the ESC is active ly
regulat ing, the
D.1 indicato r light blin ks in the in­
s trumen t clus ter.
The fo llow ing systems are integrated in the ESC :
Ant i-lock braking system (ABS)
ABS p revents the whee ls from locking whe n brak­
ing. The vehicle can sti ll be steered even during
hard brak ing. Apply steady press ure to the brake
pedal. Do not pump the pedal. A puls ing in t he
b rake pedal indicates that the system is acting to
s tabilize the vehicle .
Br ake assist system
The brake assist system can decrease brak ing dis­
tance . It increases brak ing power when the driver
presses the brake pedal q uick ly in emergency sit­
uations . You must press and hold t he b rake pedal
until the dangerous sit uat io n is over . In veh icles
with adapt ive c ruise control*, the bra ke as sist
sy stem is more sensitive if t he di sta nce detec ted
t o the vehicle dr iv ing ahead is too small. On
ve hicl es with act ivated and f unct io ni ng night vi ­
sion assist*, the brake assist system can respond mo re sensit ively if there is a warning .
Anti-slip regulation (ASR)
ASR red uces eng ine power when the drive w heels
be gin sp inning an d adapts the force to the road
conditions. This makes it easie r to sta rt, acceler ­
ate and dr ive up h ills.
Electronic differential lock (EDL)
T he EDL applies the b rakes to a whee l t h at s tarts
sp inning and tra nsfe rs t he dr ive powe r to t he
o ther driving wheel or wheels (if the veh icle is
120
equipped with a ll w hee l drive*) . T h is f unction is
not avai lab le at higher speeds .
I n extreme cases , EDL automat ic al ly swi tches off
to keep t he b rake o n the br aked wheel from ove r­
heating. The ve hicle is still working correct ly. ED L
will switc h on again automatically when condi­
tions have returned to normal.
Steering recommendation
The ESC he lps to s tabili ze th e vehicle by ch ang ing
t h e s teer ing torque.
I n veh icles with dynamic s teer ing*, ESC a lso
helps to stab ilize the s teeri ng in cr it ic al situ a­
tions.
Selective wheel torque control
Se lective wheel to rque control is used when d riv­
i ng on curves . The front whee l on the ins ide of
t h e curve or both whe els on the i nside of th e
cu rve are braked se lectively as needed. This al­
l ows mo re pre cise driving in curves .
Automatic post -collision braking system
The "a utomat ic post -coll is io n braking system"
can help to reduce the risk of sl iding and of addi­
tiona l co llisions after an acc iden t. If the a irbag
c on tro l modu le dete cts a collision above a cer tain
vehicle speed, the veh icle is braked by t he ESC.
The veh icle does not brake automatically if:
- the drive r presses the accelerator pedal, or
- the bra king force generate d by the pressed
brake pedal is greater than the b raking force
that would be in itiated by the system, or
- the ESC, the bra ke system or the vehicle elect ri­
cal system are not functioning.
A WARNING
- The ESC and its integ rated systems can not
overcome the lim its imposed by natura l
p hys ica l laws. Th is is es pec ially i mpo rtan t
on s lippery or we t roads. If the system s be­
g in a cting to s tabili ze yo ur vehicle, you
should immedi ately alte r your speed to
match the road and tra ffi c conditions. Do
not let the inc reased safety provided tempt

you into taking risks. This could increase
your risk of a collision.
- Please note the risk of a co llision increases
when driving fast, especially through curves
and on slippery or wet roads, and when driv­
ing too close to objects ahead. The ESC and
its integrated systems cannot always pre­
vent collisions -there is still a r isk of acci­
dents!
- Press the accelerator pedal carefully when
accelerating on even, slippery surfaces such
as ice and snow. The drive wheels can spin

Intelligent Technology
even when these control systems are instal­
led and this can affect driving stability and
increase the risk of a collision.
(D Tips
- ABS and ASR only function correctly when
all four wheels are equipped with identical
tires. Different tire s izes can lead to a reduc­
tion in engine power.
- You may hear noises when the systems de­
scribed are working.
ESC turns on automatically when you start the engine .

Intelligent Technology
Braking
New brake p ads
New b rake pads do no t achieve the ir full b raking
effect during the firs t 250 mi (400 km) . They
m ust be "broken in" first .
Wear
Brake pad wear depends largely o n the way the
ve hicl e is driven and on operat ing cond it ions.
This is especi ally true if you are d riving frequently
in the c ity and on c urves or with a sporty driving
style.
Operating noise
Noises may occur when bra king depend ing on the
speed, b raking force and outs ide cond it ions s uch
as temperature and humidity.
Effect of water and road salt
In ce rtain s ituations, for example after driving
through water, in heavy ra in, afte r ove rnight con­
densat ion or after washing your car, the b raking
effect can be red uce d by mo isture or ice on the
b rake rotors and brake pads. The brakes must be
"dried" first with a few careful brake applica­
tions.
At highe r speeds and with t he windshie ld wipers
turned on, the brake pads press against the bra ke
rotors for a short amount of time . This action,
which is not felt by the driver, happens at regular
intervals and ens ures a better reaction time for
the brakes in wet weathe r.
The braking effect can also be reduced if you are
driving on sa lted roads and you do not apply t he
brakes for long periods of time. The layer of salt
on the brake rotors and pads must be worn off
first when the brakes are applied.
Corrosi on
Leaving the vehicle parked for long periods of
time, low mi leage and avo iding heavy brak ing
can contribute to corrosion on the brake rotors
and to d irty brake pads.
If you usually avoid heavy b raking or if there is
corros ion present, occasional heavy braking at
122
high speeds is recommended to clean the brake
rotors and pads¢.&. .
Brake system malfunction
if you not ice that the b rake peda l t ravel has sud­
denly increased, then a br ake circuit in the du al­
c irc uit b rake system may have malfunctioned.
Drive to an authorized A udi dealer or authorized
A udi Se rvice Facility immediate ly to have the
problem corrected. On the way there, drive w ith
reduced speed and keep in m ind t hat you will
need a longer distance to stop and you will need
to press the brake peda l harder .
lo w b rake fluid level
When the brake fluid level is low, malfunctions in
the brake system may occur. The brake fluid level
i s electronically monitored.
Brake booster
The brake boos ter amp lifies the pressure you ap ­
ply to the brake pedal. It only works when the en­
gine is running .
A WARNING
- Only app ly the brakes for the purpose o f
cleaning the brake system when road and
traffic conditions permit. You must not en­
danger other road users. This i ncreases the
r is k of an accident .
-
- Never let the ve hicle roll while the engine is
s topped because this i ncreases the ris k of an
accident .
- New brake pads do no t ach ieve the ir full
braking effect dur ing the first 250 m i
( 4 00 km). They m ust be "b roken in" fi rst.
However, you can compensa te fo r the
slightly reduced brak ing force by pressing
firm ly on the brake pedal. Avo id heavy brak ­
ing during the break-in period.
- Ce rtain weather and operating condi tions
such as d riving through water, dr iv ing in
heavy rain o r driv ing after washi ng your ve­
hicle can impai r the effectiveness of the
brakes. In the winter, ice may build up on
the brake pads, rotors and dr ums. Check

" N .... 0 0 <..:l ' th ese com ponents by braking carefu lly. Ap­
plying the brakes carefully several times
dries the brakes and removes ice bui ld-up.
- The effic iency of the brakes can also be im­
paired by driving for long stretches on roads
covered w ith salt without using the brakes.
You can remove salt deposits from the brake rotors and pads by ca ref ull y applyi ng
the brakes severa l t imes.
- If the front spo iler is damaged or you install
another spoiler, ma ke sure the front w heel
bra kes are vent ilated p roperly. O therwise,
t h e brake syste m could ove rheat, wh ic h re­
duces the ir effec tiveness.
- Failure of a bra ke circuit impai rs b raking
performan ce, which incre ases bra king dis­
tance . Avoid driving the vehicle and have it
towed it to the nearest authorized A udi
dealer or author ized Audi Service Facility .
- If the brake booste r is not working, you wi ll
have to press m uch ha rder on the bra ke
peda l to compensate for the lac k of the
booster.
(D Note
- Never let the brakes "rub" by pressing the
p edal light ly when bra king is not actually
necessa ry. This causes the brakes to over­
heat and increases bra king d istance and
causes wear.
- Befo re driving downh ill a long distance on a
steep h ill, decrease your speed and select a
l ower gear. This makes use of the engine
braking effect and relieves the brakes. If
you need to b rake additionally, brake in in­
te rvals and not cont inuous ly .
(0 Tips
- If the brake booster is not working, you
must p ress the brake pedal with much mor e
fo rc e th an norma l.
-If you re trofit your vehicle wi th a front spoil­
er, whee l covers o r similar items, ma ke sure
t h at t he ai r flow to the front whee ls is not
i nte rru pted. Ot he rw ise the brake sys tem

ALL wheel drive (quattro)
Applies to: vehicles with all wheel drive
In oil wheel drive, all four wheels ore powered.
General information
In a ll wheel d rive, the d rivi ng power is divided be­
t ween a ll four wheels. Th is happens au tomatical­
ly depending on your driving behavior as well as
the current road cond itions. Also see
c::> page 120, Electronic Stabilization Control
(ESC) .
A center differentia l distrib utes the driv ing power
variably to the front and rear axle. It works to­
gethe r with selective wheel torq ue control, which
activates when driving through curves

The a ll wheel drive concept is designed for h igh
engine power. Your ve hicle is exceptionally pow­
erful and has excellent driving characterist ics
both under normal dr iv ing condit ions and on
snow a nd ice . Always read and fo llow safety pre­

Winter tires
By us ing a ll wheel drive, your vehicle has good
forward mot io n with standard t ires in winter con ­
d itions . However, in winter we recommend using
w inter or all season t ires on all fo ur wheels, be­
cause th is w ill improve the b raking effe ct.

- Also, in veh icles with all wheel drive, adapt
your driving sty le to the current road and
traffic conditions. Do not let the increased
safety provided tempt you into taking r isks,
because this inc reases the risk of an acc i­

Energy management
The starting ability is optimized
The energy management system manages the
elec trical energy distribution and optimi zes the
availability of electri cal energy for starting the
engine .
When a vehicle wi th a conventiona l energy sys­
tem is no t driven for a l ong time , the veh icle ba t­
te ry is d raine d by equ ipment ( fo r example, the
immo biliz er). In certa in circ umstances, there
could may not be enough energy to start the en­
gine.
Yo ur vehicle is equipped with an inte lligen t ener ­
gy management system fo r dist ributing elec trici ­
ty. This significantly improves the starting ability
and increases the vehicle battery life . .,.

" N .... 0 0 <..:l ' The energy management system Is made up of
battery diagno sis , idling current management ,
and dynamic energy management.
Battery diagnosis
The batte ry diagnosis determines the vehicle bat ­
tery charge level. The sensors detect the battery,
the battery current, and the battery temperature.
The current charge leve l and the performance of
the vehicle battery are determined based on this.
Idling current management
The idl ing current management decreases the
energy used whi le pa rked . With the engine
switched off, it manages the energy distribution
to the different electrical components . Data from
the battery diagnosis is taken into account for
this.
Depending on the vehicle battery charge level,
e lectrical equipment is switched off one item af­
ter the other to prevent the vehicle battery from
draining and to maintain the starting ability.
Dynamic energy management
While driving, dynamic energy management dis ­
tributes the appropriate amount of energy to the
e lectrical equipment. It controls the battery
charge level so that the amount of energy is not
greater than the amount being generated in or­
der to mainta in an optimal veh icle battery charge
level.
(D Tips
- Energy management cannot overcome the
laws of physics . Note that the charge level
and length of the vehicle battery life are
limited.
- When the start ing ability is endangered, the
(•) indicator light turns on
~ page 14.
What you should know
Maintaining the starting ability is the highest
priority.
A lot of stress is placed on the vehicle battery
when dr iving short distances, during c ity dr iving,
and at cold times of the year . A lot of energy is
Intelligent Technology
u sed but little is generated. It is also critical
when the engine is not running but electrical
equipment is switched on. In this case, energy is
used but none is generated.
In situations like this, energy management wi ll
active ly regulate the distribution of energy .
Long periods without use
If you do not drive your vehicle for severa l days or
weeks, electrical equ ipment is gradually scaled
back or switched off. This reduces energy use and
ensures the vehicle will be able to start after long
periods of time . Some convenience functions,
s u ch as interior lighting or power seat ad just­
ment, may not be ava ilable under certain circum­
stances. These conven ience functions will be
available again once you switch the ignition on
and start the engine.
With the engine switched off
The vehicle battery will dra in if you use Infotain ­
ment functions such as listening to the radio
whi le the engine is switched off .
T he vehicle's ability to start may be impaired by
the energy use, a message will appear in the In­
fotainment system display.
The message indicates that the system wi ll
switch off automatically soon. If you would like
to continue using the functions, you must start
the engine.
With the engine running
Although e lectr ica l ene rgy is generated while
driving , the vehicle battery can drain. This can
happen if litt le energy is generated but much is
used, and the charge level of the vehicle battery
is not optimal.
To restore the balance of energy, components
that require large amounts of energy are tempo­ rarily scaled back or sw itched off. Heat ing sys­
tems in particular requ ire a great deal of energy.
If you notice, for example, that the seat heating*
or rear window defogger is not work ing, then it
has been tempora rily reduced or sw itched off.
Th ese systems are available again as soon as the
energy supply has been restored. .,.

I n addition, you may notice that the idle speed
has slightly increased . That is norma l and no
cause for conce rn. By increasing the idling speed,
the additional req uired energy will be generated
and the vehicle battery will be charged.
Notice about data
recorded by the Event
Data Recorder and
vehicle control modules
E v ent Dat a Reco rd er
This vehicle is equipped with an Event Data Re­
corder (EDR). The main purpose of an EDR is to
record, in certain crash or near crash-like situa­
tions, such as an a irbag deployment or h itting a
road obstacle, data that will assist in understand­
i n g how a veh icle's sys tems performed . The EDR
is designed to record data re lated to veh icle dy­
namics and s afety systems for a sho rt pe riod of
t ime, typically 30 seconds or less. The EDR in th is
vehicle is designed to record s uch data as :
- How various systems in you r vehicle were oper­
at ing ;
- Whether or not the driver and passenger safety
belts we re buck led/fastened ;
- How far ( if at all) the drive r was depressing t he
acce le ra to r and/o r brake peda l; and,
- How fast the veh icle was trave ling .
These data can help prov ide a better understand­
ing of the circumstances in which crashes and in­
juries occur . NOTE : EDR data are recorded by your
veh icle only if a non-trivial crash situat ion occurs;
no data are recorded by the EDR under norma l
d riving conditions and no pe rsonal data (e .g.,
name, gende r, age , and crash location) are re­
corded . Howeve r, other pa rties , such as law en­
forcement, cou ld combine the EDR data w ith the
type of personally identifying data routine ly ac­
qu ired dur ing a crash invest igat ion.
To read data recorded by an EDR, specia l equip ­
ment is required, and access to the veh icle or the
EDR is needed. In addit ion to the vehicle manu ­
facturer, other parties, suc h as law enforcement,
that have the specia l equipment, can read the in-
126
format ion if they have a ccess to the vehicle or the
EDR .
Some sta te la ws rest ric t the retrieval or down­
l oad ing of data s tored by E D Rs ins talled in a veh i­
cle for the exp ress p urpose of retrieving data af ­
ter an accident or crash event without the own­ er 's consent.
Audi will not access the E DR and/or simi la r data
or give it to others -
- unless the ve hicle owne r (o r lessee if the vehi ­
cle has been le ased) 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 .
- Aud i may also use the data for research about
veh icle operation and safety performance or
prov ide the data to a th ird party for research
purposes w itho ut identify ing the specific vehi­
cle or info rmation about the ident ity of its own­
er or lessee and only afte r the reco rded vehicle
data has been accessed .
Vehicle control modules
Your vehicle is also equ ipped w ith a number of
electronic cont rol modules for va rious vehicle
systems, such as engine management, em iss ion
con tro l, airbags, and safety be lts.
These elect ronic contro l modules record data
duri ng norma l vehicle operation t hat may be
needed by tra ined techn ic ians for d iagnost ic and
r epa ir purposes. The recording cap ab ili ty o f these
modules is lim ited to data (no sound is record ­
ed). Only a sma ll amount of data is actually re­
corded over a very limited period of time, or stor­
ed when a system fault is detected by a contro l
module . Some of the data stored may relate to
vehicle speed, d irection, or braking, as well as re ­
straint system use and performance in the eve nt
of a crash . Stored data can also on ly be read and
downloaded w it h specia l equipment t hat is di­
r ectly connec ted to the vehicle.
