Fuel
Gasoline grade
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
unleaded gasoline .
Audi recommends using TOP TIER Detergent Gas­
oline. Additional information on TOP TIER Deter­
gent Gasoline can be found on the offic ial web­
site (www .toptiergas.com) .
The individua l gasoline grades are differentiated
by
octane ratings . This value is given with (R +M)/
2 equating to AKI or in RON.
The fo llow ing headings match the correspond ing
sticker in the fue l filler door.
UNLEADED FUEL ONLY MIN. (R+M) /2 87
Regula r/ MIN. RON
91 Regular
Use regu la r gaso line with minim um 87 AKI/
91
RON ~ 0 .
The max imum eng ine powe r is only reached if
p rem ium gaso line 91 A KI/ 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 recommende d.
If premium gasoline is not available, you can also
use reg ula r gaso line 87 A KI/ 91 RON . Howeve r
this does reduce t he e ngine powe r slight ly.
(D Note
- Fill ing the tank just one time with leaded
fuel or other meta llic additives will cause
permanent de te riorat io n to the catalyt ic
conve rter func tion.
- Whe n gasol ine with an oc tane r ati ng that is
too low is used, high speeds o r heavy engi ne
l o ad can lead to engi ne d amage.

(D Tips
The vehicle may be filled with fuel that has a
h igher octane rating than what is requi red by
the eng ine.
Blended gasoline
Use of gasoline containing alcohol or MTBE (methyl tertiary butyl ether)
You may use unleaded gasoline blended with al­
cohol o r MT BE (commonly referred to as oxygen­
ates) if the blended m ix tu re meets t he fo llow ing
c rit er ia:
Blend of gasoline m ethano l (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 tha n 2% co-solvents.
Blend of gasoline and ethanol (grain alcohol or
ethyl alcohol)
- Anti-k noc k index mus t be 87 AK I or higher.
- Blend must not conta in mo re than 15% etha-
nol.
Blend of gasoline and MTBE
- Anti -knock index must be 87 AKI or higher.
- Blend mus t contain no t mo re than 15% MT BE.
Seasonally adjusted gasoline
Many gasoline grades are blended to perform es­
pecially well for w inter or s umme r dr iv ing . Dur­
i ng seasonal change-ove r, we s ugges t that yo u
fill up a t busy gas stat ions w here the seasona l
adjus tment is mo re li kely to be made in t ime .
(D Note
-Metha nol fuels which do not meet these re­
quirements may cause cor rosion and dam ­
age to plas tic and rubber com ponen ts i n t he
fue l system.
- Do not use f ue ls that fa il to meet the speci ­
fie d cr iteri a in th is chap ter.

-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.

Damage or malfunction due to poor fuel q ual­
ity is not covered by the Aud i New Vehicle
Limited Warranty.

A WARNING
Fuel ignites easily and can cause serious burns
and other injuries.
- Do not smoke or have an open flame in the
area whe n fueling your vehicle or filling a
fuel conta iner because this increases the
risk of an explosion .
- Follow legal requirements when using, stor­
ing a nd transporting fuel containers .
- For safety reasons, we recommend not car­
rying fuel containers. The conta iner could be
damaged in an accident and leak fuel.
- If you must transport fuel in a fuel contain­
er, note the following:
- Never fill the fuel container 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. A lways
place the conta iner on the ground when
fill ing it .
- The fuel pump nozzle must be inserted as
far as possible into the filler opening on
the fuel container .
- If the fuel container is made of metal, the
fuel nozzle must always be in contact with
the container when filling it with f uel. Th is
prevents static electricity from discharg­
ing .
-Never spill fuel in the vehicle or the l ug­
gage compartment. Evaporated fuel is ex­
plosive and increases the ris k of se rious in­
ju ry o r dea th .
(D Note
- Remove spilled fue l from veh icle pa int im­
media tely, because it ca n damage paint .
- Never drive unt il the fuel tank is completely
empty . The irregular supply of fue l that re­
sults from that can cause eng ine misfires.
Uncombus ted fuel will ente r the exh aus t
system and increase the risk of damage to
the cata lytic converter.
@) For the sake of the environment
Do not overfill the fuel tan k, otherwise f uel
can leak o ut when the veh icle is warming up.

A WARNING
California Proposition 65 Warning:

Using the proper engine oil is important for the
functionality and s ervice life of the engine. Your
engine was factory-filled with a high -quality oil
which can usually be used throughout the entire
year .
Note
Your Limited New Vehicle Warranty does not
cover damage or malfunctions due to failure
to follow recommended maintenance and use
requirements as set forth in the Audi Owner's Manual and Warranty & Maintenance booklet .
- Use only a high quality engine oil that ex-
pressly complies with the Aud i oil quality
standard specified for your vehicle's engine.
Using any o ther oil can cause serious engine
damage.
- Do not mix any lubricants o r other additives
into the engine oil. Doing so can cause en­
gine damage.
@ Tips
If you need to add oil and there is none availa­
ble that meets the Audi o il quality standard
your eng ine requ ires, you may add a total of
no more than 0 .5 qt (0,5 l) of a h igh-quali ty
"synthet ic"oil that meets the following speci ­
fications.
- ACEA A3 or API SM with a v iscosity grade o f
SAE OW-30, SAE SW -30 or SAE SW-40.
- Fo r more information abou t engine o il t ha t
has been approved for your vehicle, please

Engine oil consumption
T he engine in your vehicle depends on an ade­
qua te amoun t of oil to lubricate and cool all of
i t s moving par ts.
In order to provide effective lub rication and coo l­
ing of in te rnal engine components, a ll internal
~ combustion engines consume a cer tain amount
;:::: of oil. Oil consumption varies from engine to en-
" ~ gine and may change sign ificantly over the life of 0
~ the eng ine . Typically, eng ines with a spec ified c:o
Ch eck ing and Filling
break-in period (see ¢ page 55) consume more
oi l during th e break-in period than they consume
after oil consumption has stabilized.
Under normal cond itions, the rate of oil con­
sumption depends on the q uality and viscos ity o f
the oil , the RPM (revolutions per minut e) at
which the engine is operated, the amb ient tem­
perature and road condit ions. Further factors are
the amount of oil dilution from w ater condensa­
tion or fuel resid ue and the oxidation level of the
o il. As any engine is subject to wear as mileage
builds up, the oi l consumption may increase ove r
t ime unt il repla cement of worn components may
become necessary.
With al l these variables coming into play, no
standard rate of o il consumption can be estab­
l ished or spec ified . T he re is no alte rnative to reg­
u la r and fre quent chec king of the o il level , see
Note .
If the yellow engine oil level warning symbo l II
in the instrument cluster lights up , you sho uld
check the o il level as soon as possible
¢
page 248 . Top off the o il at your earliest con­
venience ¢
page 248.
A WARNING
Before you check anything in the engine com­
partment, always read and heed all WARN­
INGS¢
page 244 .
(D Note
Driving with an insufficient oil level is likely to
cause severe damage to the engine.
(D Tips
- The oil pressure warning display. is not
an indicator of the oil le vel. Do not rely on
it . Instead, check the oil level in your en·
gine at regular intervals , preferabl y each
time you refuel, and always befo re going
on a long trip.
- If you have the impression your engine con­
sumes excessive amounts of oil, we recom­
mend that you consult an author ized Audi
dea ler to have the cause of your concern
prope rly diagnosed . Keep in mind that the .,,.

Wheels and Tires
General information
.,.Check your tires regularly for
damage (punctures, cuts, cracks
and bulges). Remove foreign ob­
jects from the tire tread.
.,. If driving over curbs or similar
obstacles, drive slowly and ap­
proach the curb at an angle.
.,.Have faulty tires or rims re­
placed immediately.
"'Protect your tires from oil,
grease and fuel.
.,.M ark tires before removing
them so that the same running
direction can be maintained if
they are reinstalled.
"'Lay tires flat when storing and
store them in a cool, dry location
with as little exposure to light as
possible.
(D Note
-Please note that summer and
winter tires are designed for
the conditions that are typical in those seasons. Audi recom­
mends using winter tires dur­
ing the winter months. Low
temperatures significantly de­ crease the elasticity of summ­
er tires, which affects traction
Wheels
and braking ability. If summer
tires are used in very cold
temperatures, cracks can form
on the tread bars, resulting in
permanent tire damage that
can cause loud driving noise
and unbalanced tires.
-Burnished, polished or
chromed rims must not be
used in winter driving condi­
tions. The surface of the rims
does not have sufficient corro­
sion protection for this and
could be permanently dam­ aged by road salt or similar
substances.
