Checking and Filling Fuel
Gasoline grade
The correct gasoline grade is stated on the inside
of the fuel filler door .
The vehicle is equipped with a catalytic converte r
and must only be d riven w it h
unleaded gasoline .
Audi recommends using TOP TIER Detergent Gas­
oline. Additiona l information on TOP TIER Deter ­
gent Gasoline can be found on the offic ial web­
site (www .topt iergas.com).
The individ ua l gasoline grades a re differentiated
by
o ctane ratings . This value is given with (R +M)/
2 equating to AKI or in RON.
The fo llow ing headings ma tch the correspon ding
sticker in the fue l filler door .
UNLEADED FUEL ONLY MIN. (R+M)/2 87

If premium gasoline is not availab le, yo u can also
use reg ular gasoline 87 A KI/ 91 RO N. Howeve r
this does reduce t he engine powe r sli ght ly.
CD Note
- Fill ing the tank just one t ime with lead ed
fuel or o ther meta llic additives will cause
p erm anen t de ter io rat io n to the ca taly tic
c onve rter fu nctio n.
- W hen g asoline wi th an octane ratin g th at is

Checking and Filling
{!) Tips
The vehicle may be filled with fuel t hat has a
higher octane rating than w hat is requ ired by
the eng ine .
Blended gasoline
Use of gasoline containing alcohol or MTBE (methyl tertiary butyl ether)
You may use unleaded gasoline b lended with al­
cohol o r MTBE (commonly referre d to as oxygen­
a tes) if the blende d m ixt ure meets the fo llow ing
cr it e ria :
Blend of gasoline methanol (wood alcohol or
methyl alcohol)
-Anti-knock index must be 87 AKI or higher.
- Blend must contain no more than
3% metha-
nol.
- Blend must contain more than
2% co-solvents.
Blend of gasoline and ethanol (grain alcohol or
ethyl alcohol )
-Ant i-kno ck ind ex mus t be 87 AKI or hig her.
- Blend must not co nta in mo re than
15% etha-
nol.
Blend of gasoline and MTBE
- Anti-knoc k index must be 87 AKI or h igher .
- Blend mus t contain no t mo re than
15% M TBE .
Seasonally adjusted gasoline
Many gasoline grades are blended to pe rform es­
pecially well for w inter or s ummer dr iving . D ur ­
i ng seasonal cha nge-ove r, we sugges t that yo u
fill up a t busy gas stat ions where the seasonal
adjus tme nt is mo re li ke ly to be m ade in time .
CD Note
- Metha nol fuels which do not meet these re ­
quireme nts may cause cor rosion and dam­
a ge to p last ic and r ubber co mpon ents i n t he
fue l sys te m .
- D o not use f ue ls tha t fa il to mee t the speci­
fie d cr iteria in thi s ch ap te r.

Checking and Filling
-If you a re 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 identified.
- Fuel system damage and performance prob­
lems resulting from the use of fuels differ­
ent from those specified are not the respon­
sibility of Audi and are not covered under
the New Vehicle or the Emission 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 blends, we
recommend that you switch to unblended
fuel.
Gasoline additives
A major concern among many auto manufactur­
ers is carbon deposit build-up caused by the type
of gasoline you use.
Although gasoline grades differ from one manu­
facturer to another, they have certain things in
common. All gasoline grades contain substances
that can cause deposits to collect on vital engine
parts, such as fuel 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 information on TOP TIER Deter­
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
gine of peak performance.
(D Note
Damage or malfunction due to poor fuel qual­
ity is not covered by the Audi New Vehicle
Limited Warranty.

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 234.
You can find the fuel tank capacity of your vehicle in
~ page 291.
The label on the inside of the fuel filler flap tells
you the correct fuel for your vehicle. For more in­
formation about fuel specifications, see
~ page 231.
Your vehicle fuel tank has an on board refuelling
vapor recovery system. This feature 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.
.8, WARNING
Under normal operating conditions, never car­
ry additional 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).
CI) Note
Never drive your vehicle until the fuel tank is
completely empty. The irregular supply of
fuel can cause misfiring. Gasoline could enter
the exhaust system and damage the catalytic
converter.

Fueling procedure
Fig. 174 Right rear side of the vehicle: opening the fue l
filler door
Fig . 175 Engaged fue l pump nozz le
The fuel filler door is unlocked or locked by the
central locking system .
.. Press on the fuel filler door to open
-arrow- ~
fig. 174. Your vehicle comes with a
new tank system without a cap.
.. Insert the fuel pump nozzle all the way into the
tank filler neck¢
fig. 175. Make sure it is cor ­
rectly locked in place.
• Begin fueling. Once the pump no zzle switches
off, the fuel tank is "full" . Do not fill the tank
more . Otherwise the expansion space in the
tank will be filled .
.. Pull the pump nozz le out of the tank filler neck
five seconds after it has switched off, so that
the rest of the fuel can flow out of the pump
nozzle into the filler neck.
.. Close fue l filler door until it latches.
The correct f uel type for your vehicle can be
found on a label located on the inside of the fuel
filler door. For additional information on fuel,
see ¢
page 231.
The fuel tank capacity of your vehicle is listed in
the
Technical Data section Q page 291 .
Checking and Filling
A WARNING
-Fuel ignites easily and can cause serious burns
and other injuries.
- 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 .
- Follow legal requirements when using, stor­
ing and transporting fuel containers .
- For safety reasons, we recommend not car­
rying fuel containers . The container 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 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 exp losion . Always
place the container on the ground when
fill ing it.
- The fuel pump nozzle must be inserted as
far as poss ible 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 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.
(D Note
-Remove spilled fuel from vehicle pa int im­
mediately, because it can damage paint.
- Never drive until the fuel tank is completely
empty . The irregular supply of fue l 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
Do not overfill the fuel tank, otherwise fuel
can leak out when the veh icle is warming up.

Checking and Filling
(D Tips
If adverse weat her conditio ns cause the fuel
filler door to freeze shut, p ress on the center
of the f iller door with the heel of your hand
and then try opening it again.
(!) Tips
- Your vehicle is equipped with a misfueling
guard. It allows the veh icle to be fueled on­
l y w ith the correct fuel pump nozzle .
- A worn or damaged nozzle or a nozzle that
is too small may not be able to open the
diesel misfueling guard . If this is the case,
try turning the nozzle before insert ing it in
the fuel filler neck, use a different fuel p ump, o r see an a uthorized Audi deale r or
a uthorized Audi Serv ice Facility fo r ass is­
ta nce.
- T he misfueling guard does not open when
adding fue l from a fue l conta iner. When re­
fueling with a reserve can ister, you must
use the funne l stored in the luggage com ­
partment

Check ing and F illing
Using the proper engine oil is impo rtant for the
functionality and service life of the engine. Your engine was facto ry-filled with a h igh-quality oi l
which can usually be used throughout the entire
year.
@) Note
Your Limited New Vehicle War ranty 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 Warran ty
& Maintenance booklet.
- Use only a high quality eng ine oil t hat ex-
p ressly complies with the Audi oil qua lity
standard specified for your vehicle's engine .
Using a ny o ther oil can cause serious engine
d am age.
- D o not mix any lubricants o r other addit ives
i nto the engine oil. Doing so ca n cause en­
g ine damage.
(D Tips
I f you need to add oil and there is none availa­

Engine oil consumption
T he engine in your vehicle depends on an ade­
quate amoun t of oil to lubricate and cool all of
i ts moving par ts.
In order to p rovide effective lubr ication and cool­
ing of internal engine components, all interna l
combustion engines consume a cer tain amount
of oil. Oi l co nsumption varies from engine to en ­
g ine and may change significant ly over the life of
the eng ine . Typically, eng ines with a specified
238
b reak -in period (see q page 57) cons ume more
oi l during the break-in period than they consume
after o il consumption has stab ilized.
U nder normal cond itions, the ra te of oil con ­
s u mption depends on the q ua lity and viscos ity o f
the oil , the RPM (revo lutions per minute) at
which the engine is operated, the amb ient tem­
perature and road condit ions. Further facto rs a re
the amount of o il di lution from wate r condensa­
tion or fue l resid ue a nd the oxidation level of the
o il. As any engine is subject to wear as mileage
builds up, the o il consumption may increase ove r
ti me until replacement o f wo rn components may
become ne cessary.
With a ll these va riables coming into p lay, no
standard rate of o il consumption can be estab­
li sh ed or spec ified . T he re is no alte rnative to reg­
u lar and freq uen t che cki ng of the oil level , see
Note .
If the yellow engine oil level warning symbo l l!I
in the instrument clus ter lights up , you sho uld

_& WARNING
Before you check a nyt hing in the en gine com ­
partment, always read and heed all WARN­
INGS

@ Note
D riving w ith an insufficient oil level is like ly to
cause severe damage to the eng ine.
(D Tips
- The oil pressure warning display. is not
an indicator of the oil level. Do not rely on
it . Instead, check the oil level in your en­
gine at regular intervals , preferably each
time you refuel, and always befo re going
on a long trip .
- If you have the impress io n your engine con­
sumes excessive amounts of oil, we recom­
