Operating noise
Noises may occur when bra king depend ing o n the
speed, b raking force and ou ts ide cond itions su ch
as tempe rature and humidity.
W et conditions or road salt
In ce rtain s ituat ions, for example after dr iving
through water, in heavy ra in or afte r washing
your car, the bra king effect may be reduced due
to moisture or ice on t he b rake ro to rs and br ake
pads . The br akes mus t be "dried" f irs t with a few
careful brake applications .
At highe r speeds and with the windsh ie ld w ipers
turned o n, the br ake p ads press against the br ake
r otors for a short amoun t 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 weather.
The braking effe ct can also be reduced if you are
d riving on salted roads and you do not apply t he
brakes for long periods of time . The layer of salt
on the bra ke rotors and pads must be worn off
f irst when the brakes are app lied.
Cor rosion
L eaving the vehicle par ked for long pe riods of
time, low mi leage and avoiding heavy braking
can cont ribute to corrosion on the brake rotors
and to dirty brake pads.
If you usually avo id heavy b raking or if there is
corrosion present, occasional heavy braking at h igh speeds is recommended to clean the brake
rotors and pads¢
A.
Brake system malfunct ion
If yo u no tic e th at the brake peda l travel has sud­
denly
increased, then a brake c ircuit in the dual­
circuit brake system may have malfunctioned. Drive to an aut ho rized Aud i dea le r or a uth orized
Aud i Service Facility immediately to have the
problem corrected. On the way there, drive with
reduced speed and keep in mi nd that you w ill
need a longer dista nce to stop and you w ill need
to p ress the b rake pedal harde r.
Intellig ent Technology
Low brake fluid level
When the br ake fluid level is low, malfu nctions in
the brake system may occur . The brake fluid level
is electronically monitored .
Brake booster
The brake booster ampl ifies t he p ress ure you ap­
ply to the brake pedal.
A WARNING
- Onl y ap ply the bra kes for the purpose o f
cleaning the brake sys tem when road and
traffic conditions permit. You must not en­
danger other roa d users . This increases the
risk of an accident.
-
- Never let the ve hicle roll while the engine is
stopped because this increases the risk of an
accident.
(D Note
- Never let the brakes "rub" by pressing the
peda l lightly when braking is not actually
necessary. This causes the b rakes 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
lower gear . This makes use of the engi ne
bra king effec t and relieves the brakes. If
you need to bra ke ad ditio na lly, bra ke in in­
t erva ls and not continuously.
(D Tips
- If the brake boos ter is not work ing , you
must press t he b rake peda l w ith much more
force than normal.
- If you retrofit your vehicle with a front s po il­
er, wheel covers or sim ila r i tems, make su re

All-wheel drive (quattro)
General informat ion
I n all whee l drive, the dr iv ing power is dis trib ut­
ed between all four whee ls when needed . This
happens automatically depending on your driving
behavior as we ll as the c urrent road cond it ions.
Also see ¢
page 148, Electronic stabili zation
control (ESC).
The all-whee l drive system distributes the driving
power va riably to the front and rear axle. It works
together with selective wheel torq ue control,
which act ivates when dr iv ing through curves
¢ page 148. With the sport d ifferent ial*, power
dist ribution to the rear wheels is variable and can
be adjusted using the drive se lect

The all wheel drive concept is designed for high
engine power . Your vehicle is except iona lly pow ­

Replacing tires
For vehicles w ith all wheel dr ive, only whee ls w ith
the same ro lling circumference shou ld be used .
Avoid using tires w ith different tread depths
¢ page 340, New tires or wheels .
.&_ WARNING
-Also, in vehicles with all wheel drive, adapt
yo ur dr iv ing style to the current road and
traff ic conditions. Do not let the increased
safety provided tempt you into tak ing risks,
because th is increases the r isk of an acci­
dent .
- The braking ability of your veh icle is limited
to the tract ion of the wheels . In this way, it
is not diffe rent from a two wheel dr ive vehi­
cl e. Do not be tempted to accelerate to a
high speed when the road is slippe ry, be­
ca use this increases the risk of an accident.
- Note that on wet streets, the front wheels
can "hyd roplane" if d riving at speeds that
are too high . Unlike front whee l drive
vehicles, the engine does not rev higher su d­
denly when the vehicle begins hyd roplaning .
For this reason, adapt your speed to the
road conditions to reduce the risk of an acc i­
dent .
Energy management
The starting ability is optimized
The energy management system manages the
electrical energy distribution and optimizes the
availability of electrical energy for starting the
engine.
W hen a ve hicle w ith a convent ional energy sys­
tem is not driven for a long tim e, the vehicle bat ­
t ery is dra ined by equipment (fo r example, the
i mmobilizer). In certain circumstances, there
could may not be enoug h energy to start the en­
gine .
Intellig ent Technology
Your vehicle is equipped with an intell igent ener­
gy management system for dist ributing electrici ­
ty . Th is sign ificantly improves the start ing ability
and increases the vehicle battery life.
T he ene rgy management system Is made up of
battery diagnosi s, idling cu rrent management ,
and dynamic energy management .
Battery diagnosis
T he battery diagnos is determines the vehicle ba t­
te ry charge level. The sensors determine the bat­
te ry vo ltage, the batte ry cu rrent, and the battery
temperat ure. The cur rent charge level and the
performa nee of the vehicle battery a re deter ­
mined based on this.
Idling current management
T he idling cur rent management decreases the
energy used while parked . With the engine
switched off, it ma nages the energy distribution
to the d ifferent e lectr ica l components . Data from
the battery d iagnosis is taken into account for
th is.
Depending on the vehicle battery charge level,
electrical equ ipment is switched off one item af­
ter the other to prevent the vehicle battery from
dra ining and to ma intain the starting ab ility .
Dynamic energy manag ement
While driving, dynamic energy management dis ­
t ributes the appropr iate amo unt of energy to the
electrical eq uipment. It contro ls the battery
charge level so that the amount of energy is not
greater than the amount being generated in or­
der to maintain an optimal vehicle battery charge
level.
(0 Tips
- Energy management cannot overcome the
laws of physics . Note that the charge level
and length of the veh icle bat tery life are
limited.

Intelligent Technology
What you should know
Maintaining the starting ability is the highest
priority .
A lot of stress is placed on the vehicle battery
when dr iv ing short d istances, dur ing c ity dr iving,
and at cold times of the year . A lot of energy is
used but little is gene rated .
It is also critical
when the engine is not ru nning but e lectr ica l
eq uipment is swi tched o n. In this case , energy is
used bu t none is generated.
In s ituations like this, energy management will
actively regu late the d istribution of ene rgy.
Long pe riods without use
If you do not drive your vehicle for several days or
weeks, e lectrical equipment is gradually scaled
back or switched off . This reduces energy use and
ensu res t he veh icle w ill be able to sta rt afte r long
pe riods of time. Some convenience functions ,
such as inte rior lighting or powe r seat adjust­
men t, may not be available under ce rta in ci rc u m­
s tances. These convenience functions will be
ava ilable aga in once you switch the ign ition on
and start the engine .
With the engine switched off
The vehicle battery will d rain if yo u use I nfota in ­
ment functions such as listening to the rad io
while the engine is switched
off .
If t he ve hicle's ability to s tart may be impaired by
the energy use, a message will appear in the In ­
fotainmen t system disp lay . T he message indi­
ca tes that the system wi ll switch off automatica l­
ly soon. If you would like to continue using the
functions, yo u m ust start the eng ine.
With the engine running
A lthough elect rical energy is generated whi le
d riving, the vehicle battery can d rain. This can
happen if little energy is generated but much is
used, and the charge level of the veh icle battery
is not optima l.
To restore the balance of energy, components
that require large amounts of energy are tempo­ rarily sca led back or switched
off . Heating sys­
tems in part icu lar require a great deal of energy .
154
If you notice, for example, that the seat heating*
or rear window defogger is not working, then it has been temporarily reduced or switched
off.
These systems are availab le again as soon as the
energy supply has been restored.
In addition, you may notice that the idle speed
has slight ly increased . That is normal and no
cause for concern. By increasing the idling speed,
the addit ional required energy will be generated
and the vehicle battery w ill be charged .
Notice about data
recorded by the Event
Data Recorder and
vehicle control modules
E v ent Data Recorder
This vehicle is equ ipped 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 airbag deployment or hitt ing a
r oad obstacle, data that will ass ist in understand­
i ng how a vehi cle's systems pe rformed. The EDR
i s des igned to record data related to vehicle dy­
nam ics and safe ty systems for a short per iod of
time, typica lly 30 seconds or less. The EDR in this
vehicle is designed to record such data as:
- How va rious systems in yo ur vehicle were ope r­
a ting;
- Whethe r or not the d rive r and passenger safety
belts were buckled/fastened;
- How far (if at all) the driver was depressing the
acceler ator and/or bra ke pedal; a nd,
- How fast the vehicle was traveling .
These data can help provide a better understand­ i ng of the c ircumstances in wh ich crashes a nd in­
juries occur . NOTE : EDR data are recorded by your
vehicle on ly if a non-tr iv ial crash situation occurs;
no data are re co rded by the E DR unde r no rma l
driv ing cond itions and no persona l da ta (e.g.,
name, gender, age, and crash location) are re­
corded. However, other parties, such as law en­
forcement, could combine the EDR data with the
type of persona lly identifying data rout inely ac-
quired during a crash investigation . ..,.

Check ing and F illing
Checking and Filling
Gasoline
Fuel supply
Applies to: vehicles with gaso line engine
Using the right fuel helps keep the environment
clean and prevents engine damage.
F u el r eco mmend ati on
The fuel recommended for your vehicle is unle ad­
e d pr em ium
grade gasoline . Audi recommends
using TOP TIER Detergent Gasoline with a mini­
mum octane rating of 91 AKI (95 RON). For more
information on TOP TIER Detergent Gasoline,
p lease go to the offic ial website
(www.toptiergas .com).
The recommended gasoline octane rating for
your engine can also be found on a label located on the ins ide of the fuel filler flap . This rating
may be specified as AK I or RON .
Your veh icle may also be operated using unlead­
ed regular gasoline with a minimum octane rat ­
ing of 87 AKl/91 RON. However, using 87 AKI/91
RON octane fuel w il l slightly reduce engine pe r­
forma nce.
Us e un leade d gaso lin e onl y. Unleaded gasoline
is availab le throughout the USA , Canada, and in
most European countries . We recommend that
you do not ta ke your vehicle to areas or co unt ries
where un leaded gaso line may not be availab le.
For more information on refueling your vehicle,
see
¢page 316.
Octan e rating
Octane rating indicates a gasoline's ability to re­
sist engine damaging "knock" caused by prema­
ture ignit ion and detonation . Therefore, buy ing
the correct grade of gasoline is very important to
he lp prevent poss ible engine damage and a loss
of eng ine performance.
Gasoline most commonly used in the Un ited
States and Canada has the following octane rat­
i n gs that ca n usually be found on the filler pump:
- Premium Grade: 91 - 96 AKI
314
- Regu la r Grade: 87 - 90 AK I
Explanation of the abbreviations:
AKI = Anti Knock Index = (R +M)/2 = (RON +MON)/
2
RON = Research Octane Number
MON = Motor Octane Number.
{[) Note
-Do not use a ny fue l w ith o ctane ratings low­
er than 87 AKI or 91 RON othe rw ise expen­
sive engine damage wi ll occur .
- Do
not use leaded gasoline. The use of lead­
ed gasoline will severely damage your vehi­
cle's catalyt ic converter and its ability to
control exhaust emissions .
Blended gasoline
Applies to: vehicles with gasoline engine
Use of gaso lin e conta ining alcoho l or MTBE
(meth yl tertia ry butyl ether )
You may use unleaded gasoline blended with al­
cohol or MTB E (commonly referred to as oxygen ­
ates) if the blended m ixture meets the follow ing
criteria:
Blend of g asoline methanol (wood alcohol o r
m eth yl alcoho l)
-Anti -knock index must be 87 AKI or h igher.
- Blend must contain no more than 3% metha-
nol.
- Blend must contain more than 2% co -solvents.
Blend of ga soline and ethanol (grain alcohol or
ethyl alc ohol )
- Anti-knock index must be 87 AKI or h igher .
- Blend must not conta in more than 15% etha-
nol.
Blend of gas oline and M TBE
- Anti-knock index must be 87 AK I or h igher .
- Blend must contain not mo re than 1S% MTB E.
S easonall y adjusted gasoline
Many gasoline grades are blended to perform es­
pecially well for winter or summer dr iv ing . Dur-
i ng seasonal change-over, we suggest that you .,..

(D Note
-Methanol f uels which do not mee t these re­
quirements may ca use corrosion and dam­
age to plastic and rubber components in the
fuel system.
- Do not use fuels that fai l to meet the speci­
fied criteria in this chapter.
- If you are unable to determine whether or not a particular fuel blend meets the speci­
fications, ask your service station or its fuel
supplier.
- Do not use fuel for which the contents can­
not be identif ied.
- Fuel system damage and performance prob­
lems resulting from the use of fue ls differ­
ent from those specified are not the respon­
s ibility of Audi and are not covered under
the New Veh icle or the Emiss ion Control
System Wa rrant ies.
- If you experience a loss of fue l economy or
driveability and performance problems due
to the use of one of these fuel b lends, we
recommend that you switch to unblended
fuel.
Gasoline additives
Applies to: vehicles with gasol ine engine
A majo r concern among many auto manufactur ­
ers is carbon deposit build-up caused by the type
of gasoline you use.
A lthough gasoline grades d iffer from one manu­
facturer to another, they have cer tain things in
common . A ll gasoline grades contain substances
that can cause deposits to collect on vita l engine
parts, such as fue l injectors and intake valves . Al ­
though most gasoline brands include additives to keep engine and fuel systems clean, they are not
equally effective.
Audi recommends using TOP TIER Detergent Gas­
oline. For more informat ion on TOP TIER Deter­
gent Gasoline, please go to the official website (www.toptiergas .com) .
Check ing and Filling
After an extended period o f using inadeq uate
fuels, bui lt-up ca rbon deposits can rob your en­
gine of peak performance.
(D Note
- Damage or malfunction d ue to poor f uel
quality is no t covered by the Audi New Veh i­
cle Lim ited Warranty .
- Do not add af termarket fuel addi tive prod­
u cts to your fue l tank.
Diesel fuel
Applies to: vehicles with diesel engine
