Fuel recommendation
The fuel recommended for yo ur vehicle is un
l e aded premium
grade gasoline . Audi recom
mends using TO P TI ER D ete rgent Gaso line
wi th a m inimum octane ra ting o f 91 A KI ( 95
RO N). Fo r more informa tio n o n TOP TIER De
tergent Gasoline, p lease go to the o fficia l
websi te (www. topt iergas .com) .
The re commended gasoline octane rati ng for
your engine can a lso be fo und o n a label loc at
ed on the ins ide of the fuel filler flap . This ra t
ing may be specif ied as AK I or RO N.
Your veh icle may also be operated using un
l eaded regular gasoline with a minimum oc
tane rating of 87 AKI/91 RO N. However, using
87 A KI/91 RON octa ne fue l wi ll slightly re
d uce eng ine perfo rmance .
Use unleaded ga soline only. U nleaded g aso
l ine is available th rougho ut the USA, Canada,
a nd i n most E uropean countries . We recom
mend that you do not ta ke yo ur vehicle to
areas or co untries where unleaded gasoline
may not be ava ilable.

Octane rating
Octane rating ind icates a gaso line's abili ty to
res ist eng ine dam ag ing "knoc k" ca use d by
premature ign ition and detona tion. Therefore,
buy ing the correct grade of gaso line is very
important to he lp prevent possible engine
damage and a loss of engine performance.
Gasoline mos t commonly used in the Unite d
States and Canada has the following octane r
atings t hat can usu a lly be found on the fi ller
pump:
- Premium Gra de: 91 -96 A KI
- Regular Grade : 87 -90 AKI
Explanation of the abbreviations:
AKI = Anti K nock In d ex = (R+M )/2 = (RON
+ MON)/2
R ON= Resear ch Octane Numb er
MON = Motor Octane Num ber .
(D Note
-Do not use a ny fue l w it h o ctane rat ings
lower tha n 87 A KI or 91 RO N othe rwise
expensive engi ne damage w ill occur.
- Do
not use leaded gasoli ne. The use of
leaded gasoline w ill severely damage
yo ur v ehicle's cata lytic co nve rter and its
ability to co ntrol exha ust em issions .
Blended gasoline
Applies to vehicles: with gasoline engine
Use of gasoline containing alcohol or
MTBE (methyl tertiary butyl ether )
You may use unleaded g asoline blende d wi th
alcohol o r MTBE (commonly referred to as
oxygenates) if the blende d mixture meets t he
f o llow ing criteria:
Blend of gasoline methanol (wood alcohol or
methyl alcohol)
- Anti -kno ck index must be 87 A KI or higher.
- Blend must contain no more t han 3% meth-
anol.
- Blend must contain more than 2% co -sol -
vents.
Blend of gasoline and ethanol (grain alcohol
or ethyl alcohol)
- Anti -knock index must be 87 AKI or higher .
- Blend must not conta in mo re tha n 10%
ethanol.
Blend of ga soline and MTBE
- Anti-knock index must be 87 AKI or higher. IJll,
-Blend must contain not more than 15%
MTBE.
Seasonally adjusted gasoline
Many gasoline grades are blended to perform
especially well for winter or summer driving. During seasonal change-over, we suggest that
you fill up at busy gas stations where the sea
sonal adjustment is more likely to be made in
time.
(D Note
- Methanol fuels which do not meet these
requirements may cause corrosion and
damage to plastic and rubber compo
nents in the fuel system.
- Do not use fuels that fail to meet the
specified criteria in this chapter.
- If you are unable to determine whether
or not a particular fuel blend meets the
specifications, ask your service station or
its fuel supp lier.
- Do not use fuel for which the contents
cannot be identified.
- Fuel system damage and performance
problems resulting from the use of fuels
different from those specified are not
the responsibility 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 prob lems 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 manufac
turers is carbon deposit build-up caused by
the type of gasoline you use.
Although gasoline grades differ from one manufacturer 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. Although most gasoline brands include additives to keep engine and
Fuel supply and filling your fuel tank 219
fuel systems clean, they are not equally effec
tive.
Audi recommends using TOP TIER Detergent
Gasoline. For more information on TOP TIER
Detergent 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
engine of peak performance.
Q) Note
Damage or malfunction due to poor fuel
quality is not covered by the Audi New Ve
hicle Limited Warranty.
Diesel fuel
Applies to veh icles: w ith diesel engine
Always use ULSD (Ultra Low Sulfur Diesel) sul
fur content 15 ppm or less.
The ULSD (Ultra Low Sulfur Diesel) meets the
ASTM-D-975 (grade 2).
Diesel fuel with a higher concentration than
ULSD-Diesel No. 2 ASTM 0975 and Bio-die
sel with a higher concentration than 5
% like
B11, B20 or B100 are strictly prohibited.
Service station fuel pumps are labeled with
the correct fuel information for easy recogni
tion by the user. If the diesel fuel pump is not
labeled ask the station operator what fuel is
being dispensed before filling up your vehicle.
Service stations offering Diesel fuel are gener
ally located on truck routes or major high
ways. Directories of Diesel fuel stations are
usually available at Diesel fuel stations.
Some states in the USA require permits to
purchase Diesel fuel. Check with your State
Motor Vehicle Department.
Diesel fuel may not be available outside the
USA and Canada. Be sure to check before trav-
eling to other countries.

(D Note
Never drive your vehicle until the fuel tank
is complete ly empty. The irregular supp ly
of fuel can cause misfiring . Gasoline could
enter the exhaust system and damage the
catalyt ic converter.

Fuel supply and filling your fuel tank 221
Refuelling procedure
.,. Insert the fuel nozzle from the gasoline
pump into the fuel filler neck as far as it wi ll
go .
.,. Select a medium refuelling rate so that the
nozz le switches off automatically when the
tank is full.
Putting the fuel cap back on
.,. After filling your tank, twist the fuel filler
cap clockwise as far as it wi ll go.
.,. Close the fue l filler flap.
T o avoid fuel spilling or evaporating from the
fuel tank always close fuel filler cap properly
and completely . An improperly closed fuel fill
er cap may also cause the MIL lamp¢
page 30
to come on.
A WARNING
Improper refue ling or handling of fuel can
cause fire, explosion and severe burns.
- Fuel is highly flammable and can cause
severe burns and other injur ies .
- Failure to shut the engine off while refu
eling and/or to insert the pump nozzle
fully into the fuel filler neck could cause
fue l to spray out of filler neck or to over
flow. Fuel spray and overflowing fuel can
cause a fire.
- Never use a cellular telephone while re
fue ling. The electromagnet ic rad iation
can cause spa rks that can ignite fuel va
pors and cause a fire.
- Never get back into yo ur vehicle while re
fueling.
If in exceptional circumstances
you must get back in your vehicle while
refueling, make certain that you close
the door and touch metal to discharge stat ic electricity before touching the fill
er nozzle again. Static electricity can
cause sparks that can ignite fuel vapors
released during refueling.
- Never smoke or have an open f lame any
where in or near your veh icle when refu-
eling or filling a portab le fuel conta iner. .,.
222 Fuel su ppl y and fillin g yo ur fu el t an k
- For your safety , we strongly recommend
that you do not travel with a portable
fuel container in your vehicle. The con
tainer, full or empty may leak and could cause a fire, especially in a crash.
- If, under exceptional circumstances, you
must transport a portable fuel container,
please observe the following:
- Never fill a portab le fuel container
while it is anywhere in or on the vehicle
(for example, in the luggage compart
ment, or on the trunk). Static electrici
ty can build up while filling and can ig n ite fuel vapors causing a fire .
- Always place a portable fuel container
on the ground before filling.
- Always keep the fi ller nozzle complete
ly inside the portable container before
and during filling.
- If filling a portable container made of
metal, the filler nozzle must always be
in contact with the container . This will
help prevent static electricity from dis
charging and cause a fire .
- Never sp ill fuel inside the vehicle or
luggage compartment. Fuel vapors are
h ighly flammable.
- Always observe local and state/provin
cial laws regarding the use, storage
and transpo rtation of fuel conta iners.
- Make certa in the fuel container meets
industry standards (ANSI/ ASTM
F8S2-86).
@ Note
If any fuel has spilled onto the car, it
should be removed immed iately to prevent
damage to the paint .
@) For the sake of the environment
As soon as the correctly operated nozzle
sw itches off automatically for the first
time, the tank is full . Do not try to add
mo re fuel because fuel may spill out. In
add it ion, the expans ion space in the fuel
tank will be f illed -causing the fue l to overflow when it becomes warm and pol
lute the environment .
(D Tips
-Running your engine whi le refue lling
may cause vapors to escape or even
cause fuel to spi ll out of the tank. This
would then shut off the fue l nozzle be
fore the tank is full.
- Do not refuel your vehicle with the igni
tion switched on. The fuel gauge may
otherwise not ind icate the correct fuel
level after refuelling .
- Diesel vehicles* are equipped with a die sel misfueling protector. It allows the
vehicle to be fueled only with a diesel
fuel pump nozzle. A worn or damaged nozzle or a nozzle that is too small may
not be ab le to open the diesel misfueling
protector. If this is the case, try turning
the nozzle before insert ing it in the f uel
filler neck, use a different fuel pump or
see your authorized Audi dea ler or au
thorized repair facility for assistance.
- The fuel fi ller f lap of your vehicle is not
locked when you lock the vehicle from
the inside.
