All wheel drive (quattro)
Applies to: veh icles with all whee l drive
In all wheel drive, all four wheels are powered .
General information
In all wheel drive, the driving power is divided be
tween all four wheels. This happens automatical
ly depe nding on your driving behavior as well as
the c urrent road cond itions . Also see
s>
page 116, Electronic stabilization control
( ES C).
The all wheel drive concept is designed for high
engine power . Your ve hicle is exceptionally pow
erful and has ex cellent driving characterist ics
120
both under normal d riving conditions and on
snow and ice . A lways read and follow safety pre
ca utions s>
.&..
Winter tires
By using all wheel dr ive, your veh icle has good
forward motion w it h standard t ires in win ter con
ditions . However, in winter we recommend using
winter or all season tires on
oil four whee ls, be
ca use this will improve the
broking effect.
Snow chains
I f there are snow ch ain laws , snow ch ains m ust
a lso be used on veh icles with all wheel drive
s>
page 219 , Snow chains .
Replacing tires
For vehicles with a ll w heel drive, o nly wheels with
t h e same ro lli ng ci rcumfe rence sho uld be used.
Avo id whee ls with diffe rent t read depths

Offroad vehicle?
You r Audi is no t an off road vehicle - there is not
enough ground clearance. For th is reaso n, avoid
difficul t ter rain . Also see s>
page 251.
A WARNING
-Also, in veh icles with all wheel drive, ad apt
your d riving sty le to the cu rren t road and
traffic conditions. Do not let the increased
safety provi ded tempt you into taking r is k s,
because this inc reases the risk of an acc i
dent.
- The braking abi lity of your vehicle is limited
to the traction of the whee ls. I n this way, it
is not different from a two w heel drive vehi
cle . Do not be tempted to accelerate to a
hig h speed when the road is slippery, be
cause t his i ncreases the r is k of an accident .
- Note that on wet s treets, the front wheels
can " hydrop la ne" if dr iv ing at spee ds that
are too high. Unlike front w heel d rive
veh icles, t he engine does no t rev h ig her sud
de nly when t he vehi cle begins hydrop lan ing.
F or this reason, pay atte ntion to the road
conditions rega rdless of your speed to re
duce t he risk of an accident .

Energy management
The starting ability is optimized
The energy manag ement syst em manages th e
electrical energy distribution and optimizes the
availability of electrical energy for starting the
engine.
When a vehicle w ith a conventional energy sys
tem is not dr iven for a long time, the batte ry is
d rained by equ ipment (for example the immobi l
i ze r) . In certain circumsta nces, there could may
n ot be eno ugh energy to st art the engine.
Your veh icle is equipped with an intellige nt ener
gy management system for d istr ibut ing electric i
ty . This s ignificantly im proves the s tarting ab ility
an d incr eases t he battery life.
The energy management system Is made up of
batter y diagnosis , idling current management
and dynami c energy management.
Battery diagnosis
The battery diagnosis determ ines the battery
charge level. The senso rs determ ine the battery
voltage, the battery current, and t he battery
t e m perature . Th e cu rrent charge level a nd the
p e rformance of the b attery are dete rm ined based
on this.
Idling current management
The idling c urrent management dec reases the
e n ergy used wh ile pa rked . With the eng ine
sw itched off, it manages the energy dist ribution
t o the different elect rical componen ts. Date from
b attery d iagnosis is ta ken into a ccount for this.
Depending on the battery cha rge level, e lectr ica l
eq uipment is switched off o ne item after the o th
e r, to p revent the batte ry from draini ng an d to
r eta in the s tarting ab ili ty.
Dynamic energy management
W hile driving, dy namic energy management dis
tr ibutes the appropriate amount of energy to the
e lectr ica l equipment.
It con trols the battery
ch arge level so th at more energy is not used then
i s being gener ate d in orde r to m aint ain a n op ti
mal battery charge level.
Intellig ent Technology
{!) Tips
- Energy management cannot overcome the
laws o f physics . Note that the charge level
and length of the battery life are limited.
- W hen the sta rting ability is endangered, the
(•) indicator light t urns on
¢ page 17.
What you should know
Maintaining the starting ability is the highest
priority .
A lo t of stress is p laced on t he b attery when dr iv
ing short d istances, in t raffic, and at cold times
of the year . A lot of energy is used but litt le is
generated .
It is also critical when the eng ine is
not r unning but e lectr ica l equipment is sw itched
o n . In th is case, energy is used but none is gener
ated .
In situat ions like th is, energy management w ill
active ly regulated the distr ibut ion of energy.
Long periods without use
If you do no t drive your vehicle for severa l days o r
weeks, electrical eq uipment is gradua lly scaled
back or sw itched off . This reduces e nergy use and
ensures the vehicle will be ab le to start after long
per iods of time . Some conven ience f unctions
such as opening w it h the remote control key may
not be availab le . Th ese convenience functions
will be ava ilable again once you switch the ign i
t io n on and sta rt the eng ine.
With the engine switched off
The battery w ill dra in if you use funct io ns such as
li ste ning to the radio wh ile the engine is switch
ed off .
The vehicle's ab ility to start may be impa ired by
the energy use, a message will appear in the In
fota inme nt system display .
The message indicates that the system w ill
switch off automatically soon . If you would like
to continue using the functions, you must start
the engine .

Intelligent Technology
With the engine running
A lthough electrical energy is generated whi le
driving, the battery can drain . This can happen
when little energy is generated, and much is used
and the charge leve l of the battery is not optima l.
To restore the balance o f energy, components
that requ ire large amounts o f energy are tempo
rari ly scaled back o r switched off . Heating sys
tems in particu lar require a great deal of energy.
If you notice, for example, that the seat heating*
or rear window defroster is not working, then it has bee n temporarily reduced or switched off.
These systems are available again as soon as the
energy supp ly has been restored.
In addition, you may notice that the idle speed
has slightly increased. T hat is norma l and no
cause for concern. Due to the increased idling
speed, the add itiona l requ ired e ne rgy w ill be
generated and the battery w ill be cha rged.
Notice about data recorded by the Event
Data Recorder and vehicle control modules
E vent Data Recorder
This vehicle is equipped wi th an Event Da ta Re
corde r (EDR) . The main purpose of an EDR is to
record, in certain crash o r near crash-like situa
tions, such as an a irbag deployment or h itting a
road obstacle, data that will assist in understand
ing how a veh icle's systems performed . The EDR
is designed to record data related to veh icle dy
namics and safe ty systems for a sho rt pe riod of
time, typically 30 seconds or less. The EDR in this
veh icle is designed to reco rd s uch data as:
- How various systems in your vehicle were oper
at ing;
- Whether or not the driver and passenger safety belts we re buckled/fastened;
- How far ( if at all) the driver was depress ing the
acce lerator and/or brake peda l; and,
- How fast the ve hicle was trave ling.
These data can help provide a better understand ing of the circ umstances in which crashes and in
juries occur. NOTE: EDR data are recorded by your veh icle only if a non-trivia l crash situat ion occurs;
no data are recorded by the EDR under norma l
122
driving cond itions and no personal data (e .g .,
name, gender, age, and crash location) are re
corded. However, other parties, such as law en
fo rcement, co uld comb ine the EDR data with the
type of persona lly identifying data rout inely ac
quired du ring a crash investigation .
To read data recorded by an EDR, spec ial eq uip
ment is required, and access to the vehicle or the
EDR is needed. In addition to the ve hicle manu
facturer, other part ies, such as law enforcement,
t h at have the spec ial eq uipment, can read the in
fo rmat io n if they have access to the vehicle or the
EDR .
Some state laws restrict the retrieval or down
l oad ing of data stored by ED Rs ins talled in a ve hi
cle for the exp ress p urpose of ret riev ing data af
te r an accident or c rash event withou t the own
e r's consent.
Audi will not access the EDR and/or simi la r data
or g ive i t to others -
- unless the ve hicle owner (or lessee if the vehi
cle has been leased) agrees; o r
- upon the offic ial request by the police; or
- upon the order of a court o f law or a govern -
ment agency; or
- for the defense of a lawsuit thro ugh the judicia l
discovery process.
- Audi may a lso use the data for research about
veh icle operation and safety perfo rmance or
prov ide the data to a third party for research
purposes without identify ing the specific vehi
cle or information about the ident ity of its own
er or lessee and only afte r the recorded vehicle
data has been accessed.
Vehicle control modules
You r vehicle is also eq uipped with a number of
electronic control modules for various vehicle
systems, such as e ngine management, em iss ion
contro l, airbags, and safety be lts.
These elect ronic contro l modules record data
dur ing norma l vehicle operation that may be
needed by trained techn ic ians for d iagnost ic and
r epa ir purposes. The recording capab ility of these
modules is lim ited to data (no sound is record
ed). Only a sma ll am ount of data is actually

Checking and Filling
Gasoline fuel
Gasoline grade
A pp lies to: ve hicles w ith gaso li ne engines
The correct gasoline grade is stated on the inside
of the fuel filler door .
The vehicle is equipped with a catalytic converter
and must only be driven w ith
unlead ed ga soli ne.
Aud i recommends using TOP TIER Detergent Gas
oline. Additional information on TOP TIER Deter
gent Gasoline can be found on the official web
site (www .toptiergas.com) .
The individua l gasoline grades are differentiated
by
oct ane rating s. This value is given with (R +M)/
2 equating to AK I or in RON.
The fo llowing headings match the corresponding
sticker in the fuel fi ller door .
UNLEADED FUEL ONLY MIN. (R+M) /2 87
R egula r/ MIN. RON
91 Regular
Use regu lar gasoline with minim um 87 AKI/
9 1 RON ~@ .
The max imum engine power is only reached if
p rem ium gasol ine 91 AKI/ 95 RON is used.
UNLEADED FUEL ONLY PREMIUM MIN . (R
+M )/2
91 / SUPER MIN. RON 95
Using premium gasoline with m inim um 91 AKI/
95 RON is recommended.
If premium gasoline is not available, you can also
use regula r gasoline 87 AKI/ 91 RON . However
this does reduce the engine powe r slight ly.
CD Note
- Fil li ng the tank just one time with leaded
fuel or other meta llic additives will cause
permanent deteriorat ion to the cata lyt ic
conve rter func tion.
- When gasoline with an octane rati ng that is
too low is used , h igh speeds o r heavy engine
l oad can lead to engi ne dam age.
184
(D Tips
The vehicle can be fi lled with fue l that has a
h igher octane rating than what is requi red by
the eng ine.
Blended gasoline
App lies to : vehicles wit h gasol ine engi ne
U se of g asoline cont aining alcohol or MTBE
(m ethyl tertiary butyl ether )
You may use unleaded gasoline blended with al
cohol o r M TBE (commonly referred to as oxygen
ates) if the blended m ixt ure meets the fo llow ing
c rit eria:
Blend of ga soline methanol (wood alcohol or
methyl alcohol)
- 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 alcoh ol or
ethyl alcohol)
- Anti-knoc k index must be 87 A KI or h igher.
- Blend must not conta in more than 15% etha-
nol.
Blend of gasoline and MTBE
- Anti -knock index must be 87 AKI or higher.
- Blend mus t contain no t more than 15% MTBE .
Seasonall y adjusted ga soline
Many gasoline grades are blended to perform es
pecially well for winter or summer dr iv ing . Du r
i ng seasonal change-over, we suggest that you
fill up at busy gas stat ions where the seaso nal
adjustment is mo re l ikely to be made in t ime .
CD Note
-Methanol fuels which do not meet these re
quirements may cause corrosion and dam
age to plasti c and rubber components in the
fue l system.
- Do not use fue ls that fa il to meet the speci
fied cr iteria in th is chapter.
...

<( co .... N r--N .... 0 r--> co
-If you are unable to determine whether or
not a particular fuel blend meets the speci
ficat ions, 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 diffe r
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 Warrant ies .
- If you experience a loss of fue l economy or
driveability and pe rformance problems due
to the use of one of these fuel blends, we r ecommend that you switch to unblended
fuel.
Gasoline additives
A ma jor concern among many auto manufactur
ers is carbon deposit build-up ca used by the type
of gasoline yo u use.
A lt hough 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 .
Aud i recommends using TOP TIER Detergent Gas
oline. For more informat ion on TOP TIER Dete r
gent Gasoline, please go to the official website
(www.toptiergas .com) .
After an extended period of using inadequate
fuels, carbon deposit build-ups can rob your en
g ine of peak performance.
CD Note
Damage or malfunction due to poor fuel q ual
ity is not covered by the Aud i New Vehicle
Limited Warranty.

To avoid fuel spilling or evaporating from the fuel
tank always close fue l filler cap properly and
completely . An improperly closed f uel f iller cap
may also cause the MIL lamp
~ page 21 to come
on.
A WARNING
Not pay ing attention w hen fueling or han
dling f uel incorrectly can lead to fires , explo
sions o r serious injur ies .
- Fue l ignites easily and can cause serious
burns and other injur ies .
-
-If you do not switch the engine off when fu
eling a nd/or do not insert the fuel nozzle
comp letely into the tank open ing, fuel can
leak out o r run over. Leaked fuel can ign ite
and start a fire.
- Do not use the telephone wh ile f uel ing . The
elec tromagneti c rays can cause sparks,
which can ignite fue l vapors and s tart a fire.
- Do not sit in your vehicle wh ile fue ling. If
you must make an excep tion and enter yo ur
veh icle aga in while fueling, close the door
and touch me tal to discharge static electric
ity before touching the f uel nozz le . 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
fue l conta iner because this increases the
risk of an explosion.
- For your safety, carrying fuel containers in
your veh icle is not recommended. Whether
full or empty, the container can leak and
cause a fire in the even t of an acc ident.
- If you must make an exception and trans
port a fuel containe r, note the follow ing:
- Never fill the fuel co ntainer with fue l
while it is in or on the vehicle. Static e lec
tricity is discharged when fi lling which can
cause the fuel vapors to ignite and in
creases the risk of an exp losion.
- Always place a fuel conta iner on the
ground before fill ing.
- Always ho ld the fuel nozzle completely in
the fue l container when filling.
Page 187 of 272
<( co ..... N
" N ..... 0 r--. > 00
-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
empty . The irregular supply of fuel that re
sults from that can cause engine misfires. Uncombusted fuel will enter the exhaust
system and increase the risk of damage to
the catalytic converter.
@) For the sake of the environment
If the fuel nozzle is used correctly, it will ind i
cate that the tank is full the first time it
sw itches off automatically. Do not try to add
more fuel, because it can spill over. Also, the
expansion space in the tank will fill, which can
result in fuel spilling out when it becomes
warm and polluting the environment.
@ Tips
Fuel can age and may lead to problems when
starting . Audi recommends replacing the fuel
in your vehicle within six months.
@ Tips
- If the engine is running while fueling, va
pors can escape or the fuel can spill over.
Because of th is, the fuel nozzle switches off
before the tank is full.
- Do not fue l the vehicle when the ignition is
switched on . Otherwise, the fuel gauge may
not show the correct level after fueling the
vehicle.
Checking and Filling
-The fuel filler door on your vehicle does not
lock when you lock the vehicle from the in
side.
Fuel filler door emergency release
If the central locking system is faulty, the fuel
filler door can be unlocked manually.

Catalytic converter
Applies to: vehicles with gasoline engine
It is very important that your emission control
system (catalytic converter) is functioning prop
erly to ensure that your vehicle is running in an
environmentally sound manner.
.. Always use lead-free gasoline c:> page 184, Gas
oline grade .

Checking and Filling
"'Never put too much motor oil in your engine
¢ page 193 , Checking the engin e oil lev el and
adding oil.
"'Never try to push- or tow-star t your vehicle.
The catalytic converter is an efficient "clean-up"
device built into the exhaust system of the v ehi
cle. The catalytic converter burns many of the pollutants in the exhaust gas before they are re
leased into the atmosphere .
The exclusive use of unleaded fuel is critically im
portant for the life of the catalytic converter and
proper functioning of the engine.
A WARNING
The temperature of the exhaust system is
high, both when driving and after stopping
the engine.
-
- Never touch the exhaust tail pipes once they
have become hot . This could result in burns .
- Do not park or operate the vehicle in areas
where the hot exhaust system may come in
contact with dry grass, brush , fuel spill or
other material which can cause a fire.
- Do not apply additional undercoating or
rustproofing on or near the exhaust mani
fold, exhaust pipes, catalytic converter or heat shields. During driving, the substance
used for undercoating could overheat and
cause a fire.
(D Note
- Be aware that just one tank filling with
leaded fuel will already seriously degrade
the performance of the catalytic converter.
- Do not exceed the correct engine oil level
¢page 193.
-Do not drive until the fuel tank becomes
completely empty. The engine could mis
fire. Unburned fuel could also get into the
exhaust system and this could cause the
catalytic converter to overheat.
- Do not switch off the ignition while the vehi
cle is moving.
- Do not continue to operate your vehicle un
der these conditions, as otherwise fuel can reach the catalytic converter. This could re-
188
sult in overheating of the converter, requir
ing its replacement.
- To assure efficient operation of the Emis
sion Control System:
- Have your vehicle maintained properly and
in accordance with the service recommen
dations in your Warranty
& Maintenance
booklet.
- Lack of proper maintenance as well as im
proper use of the vehicle will impair the
function of the emission control system
and could lead to damage.
@ For the sake of the environment
Even when the Emission Control System is op
erating properly, the exhaust gas can have a
sulfur-like exhaust gas smell under some op
erating states. This depends on the sulfur
content of the fuel being used. Using a differ
ent brand of fuel may help, or filling the tank
with lead-free super grade gasoline.
Engine compartment
Working in the engine compartment
Special care is required if you are working in the
engine compartment
For work in the engine compartment, such as
checking and filling fluids, there is a risk of in
jury, scalding, accidents, and burns. For this
reason, follow all the following listed warnings
and general safety precautions. The engine
compartment is a dangerous area.
£:=? &. -
A WARNING
To reduce the risk of injuries, complete the
following steps before opening the hood:
- Turn the engine off.
- Switch the ignition off.
- Set the parking brake.
- Place the selector lever in the P position .
- Let the engine cool down .
