necessary. This causes the brakes to over ­
heat and increases bra king distance and
causes wear .
- Befo re driving downhi ll 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
you need to brake additionally, b rake in in­
t e rvals a nd not continuously .
(D Tips
-If the brake booster is not working, you
must press the brake pedal with much more
force than normal.
- If you retrofit you r vehicle with a front spoil­
e r, whee l covers o r similar items , make sure
that the a ir flow to t he fron t wheels is not
i nte rr u pted . Othe rw ise the brake sys tem

All wheel drive (quattro)
Applies to: vehicles with all wheel drive
In all wheel drive, all four wheels are powered.
General information
In all whee l drive, the dr iv ing power is divide d be­
tween all four whee ls. This happens automatical ­
l y depending on yo ur driv ing behavior as we ll as
the cur rent road conditions . Also see
¢ page 120 , Electronic Stabilization Control
(ESC).
A center d ifferential distributes the driving powe r
varia bly to the front and rea r ax le. It wor ks to­
gether w ith selective whee l torque contro l, w hich
activates w hen d riving through curves

Winter tires
By using all wheel drive, your vehicle has good
forward motion with standard tires in winter con­
ditions . However, in winter we recommend using
winter or all season tires on all four wheels, be­
cause this will improve the braking effect.
Snow chains
If there are snow chain laws, snow chains must
also be used on vehicles with all wheel drive
¢ page 227, Snow chains.
Replacing tires
For vehicles w ith all whee l dr ive, only whee ls w ith
the same rolling circumference should be used .
Avoid using tires with different tread depths
¢ page 218, New tires or wheels.
Offroad vehicle?
Your Audi is not an offroad vehicle -there is not
enough ground clearance. For this reason, avoid
difficult terrain.
_& WARNING
-Also, in vehicles with a ll wheel drive, adapt
your dr iving style to the current road and
traff ic conditions. Do not let the increased
safety provided tempt you into taking risks,
because this increases the risk of an acci­
dent .
- The braking ability of your vehicle is limited
to the traction of the wheels . In this way, it
is not different from a two wheel dr ive vehi­
cle. Do not be tempted to accelerate to a
high speed when the road is slippery, be­
cause this increases the risk of an accident .
- Note that on wet streets, the front wheels
can "hydroplane" if driving at speeds that
are too high. Unlike front wheel drive
vehicles, the engine does not rev higher sud­
denly when the vehicle begins hydroplaning .
For this reason, adapt your speed to the
road conditions to reduce the risk of an acci­
dent.

cator light in the instrument cluster comes
on, the rear spo iler may not have deployed.
- Never drive at speeds higher than 85 mph (140 km/ h) if the spoile r is not deployed.
Have the spoiler inspected as soon as possi­
ble by an author ized Audi dealer or qualif ied
workshop.
-Always obey speed limits and other tra ffic
laws .
(D Note
-Never push on the vehicle on the rear spoi l­

- To prevent damage to the rear spoiler do
not lean o r place anything on it.
- Only opera te the rear spoiler man ually when
the luggage compartment lid is close and
the rear spoiler movi ng pa rts a re not
blocked. Otherwise, damage could occur.
(D Tips
Clean the rear spoi ler compartment eve ry 2 to
3 mont hs. To function correctly, the rear
spoiler m ust be free of ice, snow and leaves.

Energy management
' The starting ability is optimized
T he energy management system manages the
electrical energy distribution and optimizes the
availability of electrical energy for starting the
engine.
When a vehicle with a conventional energy sys ­
tem is no t drive n for a long time, the ve hicle bat­
te ry is drained by equ ipment (fo r example, t he
i mmob il iz er). I n cer ta in circ umstan ces, the re
could m ay no t be e nough energy to s tart the en­
gine.
You r vehicle is equipped with an inte lligent e ner­
gy management system fo r dist ributing elec trici­
ty. Thi s sign ifica ntl y improves the start ing ability
and incre ases the vehicle battery life .
The ene rgy ma nagement system Is made up of
battery diagnosi s, idling current management ,
and dynamic energy management .
Battery diagnosis
T he battery diagnos is determines the vehicle bat ­
tery charge level. The sensors detect the ba tte ry,
the batt ery cur rent, and t he battery temperature .
The curren t cha rge level and the pe rformance of
t h e ve hicle battery are dete rm ined based on th is .
Idling current management
The idling current management decreases the
energy used while parked . With the engine
switched off , it m anages t he e ne rgy dis trib ution
to the d ifferen t electr ica l components . Data from
t h e b attery d iagnosis is ta ken into a ccou nt for
th is .

greater than the amount being generated in or­
der to maintain an optima l vehicle battery charge
l evel.
(D Tips
- Energy management cannot overcome the
laws of physics. Note that the charge level
and length of the vehicle batte ry life are
li mited.
- When the starting ability is endangered, the
(•j 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 driving short distances, during c ity driving,
and at co ld times of the year. A lot of energy is
used but little is generated. It is a lso critical
when the engine is not running but e lectr ica l
equ ipment is switched o n. In th is case, energy is
used but none is generated .
In s ituations like this, energy management will
actively regu late the distribution of ene rgy.
Long periods w ithout use
If yo u do not drive you r vehicle for several days or
weeks, e lectrica l equipment is gradually sca led
back or switched off. This reduces energy use and
ens ures the veh icle w ill be able to start after long
periods of time. Some convenience functions,
such as interior lighting or power seat adjust­
ment, may not be available under certain circum­
stances . These convenience functions will be
ava ilable again once you switch the ig nition on
an d s tart the engi ne.
With the engine switched off
T he vehicle battery will drain if yo u use I nfota in ­
ment f unctions such as listening to the rad io
while the eng ine is switched off .
The vehicle's ability to start may be impaired by
the energy use, a message will appear in the In ­
fotainment system d isplay .
The message ind icates that the system will
switch off automatically soon. If you wou ld like
Intellig ent Technology
to cont inue using the functions, you must start
t h e engine.
With the engine running
Alt hough e lectr ica l energy is ge nerated wh ile
dr iv ing , the ve hicle ba ttery can dra in. This ca n
happen if li ttle ene rgy is generate d but much is
u sed , and the charge level of the vehicle battery
is not optimal.
T o res to re the balance of ene rgy, componen ts
t h at require large amoun ts of ene rgy are tempo ­
rarily scaled back or switched off . Heat ing sys ­
tems in partic ula r req uire a great dea l 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.
These systems are availab le aga in as soo n as the
energy sup ply has bee n restored .
In add ition, you may notice that the idle speed
has slig htly increased. That is normal and no
cause for concern . By increas ing the idling speed,
the addit ional required energy will be generated
and the vehicle battery will be charged .
Notice about data
recorded by the Event
Data Recorder and
vehicle control modules
Event Data Recorder
Th is vehicle is equ ipped w ith an Event Data Re­
corder (EDR) . The ma in purpose of a n EDR is to
r ecord, in certai n cras h or nea r crash-like situa­
ti ons, s uch as an airbag deployme nt o r hi ttin g a
road obsta cle, da ta t hat w ill ass ist in underst and­
i ng how a vehicle 's systems performed . The EDR
is des igned to record data related to vehicle dy ­
namics and safety systems for a short perio d of
t ime, typ ica lly 30 seconds or less . The EDR in this
vehicle is designed to record such data as:
- How va rious systems in your vehicle were ope r­
ating;
- W het her o r not the drive r and passenge r safety
be lts were b uckled/fastened;
- How far (if at all) the driver was dep ressing the
accelerator and/or bra ke pedal; and, .,,.
127

Intelligent Technology
-How fast the vehicle was traveling.
These data can help provide a better understand­ ing of the circumstances in which crashes and in­
juries occur. NOTE : EDR data are recorded by your
vehicle only if a non-trivial 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
forcement, could combine the EDR data with the
type of personally identifying data routinely ac­
quired during a crash investigation.
To 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 similar data
or give it to others -
- unless 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 or a govern-
ment agency; or
- for the defense of a lawsuit through the judicial
discovery process.
- Audi may also use the data for research about
vehicle opera tion 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.
128
These electronic control modules 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 limited period of time, or stor­
ed when a system fault is detected by a control
module . Some of the data stored may relate to
vehicle speed , direction , or braking, as well as re­
straint system use and performance in the event
of a crash. Stored data can also only be read and
downloaded with special equipment that is di­
rectly connected to the vehicle.
@ Tips
Your vehicle may be equipped with Audi con­
nect. Your use of certain Audi connect fea­
tures requires wireless services that are pro­
vided by a third party wireless telecommuni­
cations provider. For details regarding how in­
formation obtained through Audi connect is
collected, processed, transmitted, used, and
shared, please see your contract with the
wireless telecommunications provider and the

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 .
Fuel reco mm endati on
The fuel recommended for your vehicle is unlead­
ed 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 official website
(www.toptiergas .com) .
The recommended gasoline octane rating for
your engine can also be found on a label located
on the inside of the fuel filler flap . Th is rating
may be spec ified as AKI or RON.
Your vehicle may also be operated using unlead­
ed regular gasoline with a min imum octane rat ­
ing of 87 AKl/91 RON. However, using 87 AKl/91
RON octane fuel will slightly reduce engine pe r­
formance.
U se unlea ded gas oline only. Unleaded gasoline
is available throughout the USA, Canada, and in
most European count ries . We recommend that
you do not ta ke your vehicle to areas or countries
where un leaded gasol ine may not be availab le.
For more information on refueling your vehicle,
see
~ page 193.
Octane r ating
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
h e 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
ings that can usually be found on the filler pump:
- Premium Grade: 91 -96 AKI
Ch eck ing and Filling
- Regu lar Grade: 87 -90 AK I
E xplanation of the abb reviations:
AK I=
Anti Knock Index = (R +M)/2 = (RON +MON)/
2
RON = Research Octane Number
MON = Motor Octane Number.
(D Note
- Do not use any fue l w ith octane ratings low­
er than 8 7 AKI or 91 RON otherwise expen­
sive engine damage w ill occur .
- Do
not use leaded gasoline. The use of lead­
ed gasoline will severe ly damage your vehi­
cle's catalytic converter and its ability to
control exhaust emissions .
Blended gasoline
Applies to: vehicles with gasoline engine
Use of gas olin e con tainin g alcoh ol or MTBE
( meth yl t ert ia ry but yl 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 gasolin e methanol (wood alcohol or
methyl 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 g asoline and ethanol (grain alc oh ol or
e th yl alcoh ol)
- Anti-knock index must be 87 AKI or h igher .
- Blend must not conta in more than 15% etha-
nol.
Bl end of g asoline and MTBE
-Anti-knock index must be 87 AK I or h igher.
- Blend must contain not mo re than 15% MTBE.
Se asonall y adjust ed ga soline
Many gasoline grades are blended to perform es­
pecially well for winter or summer dr iving . Dur-
ing seasonal change-over, we suggest that you ..,.
191

Check ing and F illing
fi ll up at busy gas stations where the seasona l
adjustm ent is more likely to be mad e in time .
0 Note
-Me thanol f uels which do no t meet these re­
quirements may cause corrosion and dam­
age to plastic and rubber components in the
fuel system .
- Do not use fuels that fail to meet the spec i­
fied criteria in this chapter .
- If you are unable to determine whether or not a particular fuel blend meets the spec i­
fications, ask your service station or its fuel supplier.
- Do not use fuel for which the contents can­
not be identified.
- 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 Warranties.
- If you experience a loss of fuel economy or
driveability and performance problems due
to the use of one of these fuel b lends, we
r ecommend that you switch to unblended
fuel.
Gasoline additives
A ma jo r concern among many auto manufactur­
ers is carbon deposit build- up ca used 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 . All gaso line 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 TIE R Detergent Gas­
oline. For more information on TOP TIER Deter ­
gent Gasoline, please go to the official website (www.toptiergas .com) .
192
After an extended period o f using inadequate
fuels, carbon deposit bui ld-ups can rob your en­
gine of peak performance.
([) Note
Damage or ma lf u nction due to poor fue l qual ­
ity is not covered by the Audi New Vehicle
Limited Warranty .
Diesel fuel
Applies to: vehicles wi th diese l en gin e
Always use ULSD (Ultra Low Sulfur Diese l) No. 2 .
The ULSD No. 2 meets the ASTM D97S.
D iesel fuel w ith concentrations of b iod iesel high­
er than 5 % such as B l 1, B20 or BlOO are st rict ly
prohibited .
Se rvice station fuel pumps are labe led wi th the
correc t fu el i nfo rmation for easy recogn ition by
the user . If the diesel fue l pump is not labe led
ask the station operator what fue l is being dis­
pensed before filling up your vehicle .
U LSD No . 2 may no t be ava ilable outside the USA
and Canada . Be s ure to check befo re t raveling to
other countries .
U LSD No . 2 can become th ic k e r i n very co ld tem­
peratures, and this can impa ir the e ng ine's s tart­
i ng and running . Depend ing on the season, gas
stations provide ULSD No . 2 that flows better in
cold temperatures so that you can continue oper­
at ing your vehicle as usual.
(D Note
- Your vehicle's diese l engine was designed
so ley for use with ULSD No . 2 . Therefore,
never use gasoline, heating oil, other fuels
or flow improvers. These contain substances
that will severely damage the fuel system and the engine. Such damage will not be
covered by your New Vehicle Limited War­
ranty.
- If you put any amo unt of incorrect fuel in
the fuel tank, do not start the engine under
any c ircumstances. Immed iate ly contact the

Refueling
Fuel filler neck
The fuel filler neck is located on the right rear
side panel behind the fuel filler flap.
If the power locking system should fail , you can
still open the flap manually - for detailed instruc­
tions see
~ page 195 .
You can find the fuel tank capacity of your vehicle in
~ page 262 .
The label on the inside of the fuel filler flap tells
you the correct fuel for your vehicle. For mo re in­
formation about fuel specifications , see
~ page 191 .
You r vehicle fuel tank has an onboa rd refuelling
vapor recovery sys tem . This fea tu re helps to pre­
vent fuel vapors from escaping from the tank and polluting the environment while you refuel your
vehicle. In order to fill the tank properly while
protecting the environment, please follow this
refueling procedure carefully.
_& WARNING
Under norma l operating conditions, never car­
ry additiona l fuel containers in your car. Gas
canisters and other containers used to trans­
port fuel can be dangerous. Such containers,
full or empty, may leak and could cause a fire
in a collision . If you must transport fuel to
use for your lawn mower, snow blower, etc.,
be very careful and always observe local and
state laws regarding the use, transportation
and storage of such fuel containers. Make cer­
tain the container meets industry standards
(ANSI/ASTM F852 -86).
(D Note
Never drive your vehicle until the fuel tank is
completely empty. The irregular supply of
fue l can cause misfiring. Gasoline could enter
the exhaust system and damage the catalyt ic
converter.

Checking and Filling
The fuel tank capacity of your vehicle is listed in
the
Technical Data section ~ page 262.
To avoid fuel spilling or evaporating from the fuel
tank always close fuel cap properly and com­
pletely. An improperly closed fuel filler cap may
also cause the MIL lamp~
page 25 to come on.
A WARNING
Not paying attention when fueling or han­
dling fuel incorrectly can lead to fires, explo­
sions or serious injuries .
- Fuel ignites easily and can cause serious burns and other injuries .
- If you do not switch the engine off when fu­
eling and/or do not insert the fuel no zzle
completely into the tank opening, fuel can
leak out or run over . Leaked fuel can ignite
and start a fire .
- Do not use the telephone while fueling. The
electromagnetic rays can cause sparks,
which can ignite fuel vapors and start a fire .
- Do not sit in your vehicle while fueling . If
you must make an exception and enter your
vehicle again while fueling, close the door
and touch metal to discharge static electric­ity before touching the fuel nozzle . Static
electricity can create sparks, which can ig­
nite vapors when fueling.
- Do not smoke or have an open flame in the
area when fueling your vehicle or filling a
fuel container because this increases the risk of an explosion.
- For your safety, carrying fuel containers in
your vehicle is not recommended. Whether
full or empty, the container can leak and
cause a fire in the event of an accident.
- If you must make an exception and trans­
port a fuel container, note the following:
- Never fill the fuel container with fuel
while it is in or on the vehicle. Static elec­
tricity is discharged when filling which can
cause the fuel vapors to ignite and in­
creases the risk of an explosion.
- Always place a fuel container on the
ground before filling.
- Always hold the fuel nozzle completely in
the fuel container when filling.
194
-If the fuel container is made of metal, the
fuel nozzle must always be in contact with
the container when filling it with fuel. This
prevents static electricity from discharg­
ing .
-Never spill fuel in the vehicle or the lug­
gage compartment . Evaporated fuel is ex ­
plosive and increases the risk of serious in­
jury or death .
- Follow legal requirements when using, storing and transporting fuel containers .
- Make sure the fuel container conforms to industry standards (ANSI/ASTM F852-86).
(D Note
-Remove spilled fuel from vehicle paint im­
mediately, because it can damage paint.
- Never drive until the fuel tank is completely

sults from that can cause engine misfires.
Uncombusted fuel will enter the exhaust
system and increase the risk of damage to
the catalytic converter .
(D Note
Applies to: vehicles with diesel eng ines
If the fuel tank runs completely empty, the
ignition must remain switched on for at least
30 seconds after refueling before starting the
engine. It may take longer than usual for the
engine to start, even up to a minute. This is
because the air must first bleed out of the
fuel system when starting the engine.
@ For the sake of the environment
Do not overfill the fuel tank, otherwise fuel
can leak out when the vehicle is warming up.
(y Tips
The fuel filler door on your vehicle does not lock if you lock the vehicle from the inside.
