Fuel supply and filling your fuel tank
Gasoline
Fuel supply
Using the right fuel helps keep the environment clean and
prevents engine damage .
Fuel recommendation
The fuel recommended for your vehicle is unleaded premium grade
g asoline . See also :::>
page 341, "D ata ". Aud i recommends using TO P
TIER Detergent Gasoline with a minimum octane ra ting of 91 AKI (95
R O N). For more information on TOP TIE R Detergen t Gasoline, please
go to the official website (www. toptiergas .com) .
Th e recommended gasoline octane rating for your engine can also be
found on a labe l located on the ins ide of t he fue l fille r flap. This rating
may be specified as AKI or RON .
Your vehicle may also be ope rated us ing unleaded reg ular gasoline
with a minim um octane rating of 87 AKI/91 RON. However, us ing 87
AKI/91 RON octane fuel will slig htly reduce engine performance.
Use un leaded ga soline only. U nleaded gaso line is available
throughout the USA, Canada, and in most E uropean co untries. We
recommen d that you do not ta ke your veh icle to areas or co unt ries
where unleaded gasoline may not be available.
F or more in formation on re fueling yo ur vehicle, see:::>
page 272.
Octane rating
Octane r ati ng indi cat es a gaso line's abi lity to resis t engi ne damag ing
"knock" caused by premature ignition and detonat ion. Therefore,
buying the correc t g rade o f gasol ine is very impo rtan t to help preve nt
possible engine damage and a loss of engine performance .
Gaso line most common ly used in the United States and Canada has
the following octa ne rat ings tha t ca n usually be fou nd on the filler
pump :
Safety first
• Premium Grade: 91 - 96 AKI
• Regular Grade: 87 - 90 AKI
Explanation of t he abb reviations :
AKI= Anti Knock Index= (R +M)/2 = (RON+ MON)/2
RO N= Research Octane Number
M ON= M otor Octane Num ber.
0 Note
• Do not use any fue l with octane rat ings lower than 87 AKI o r 91
RO N otherwise expens ive engine damage will occ ur.
• Do
not use leaded gasoline. The use of lea ded gasoline w ill
severely damage your veh icle 's cata lytic converter and its abi lity to
cont rol exhaust emissions .•
Blended gasoline
Use of gasoline containing alcohol or MTBE (methyl
tertiary butyl ether)
Yo u may use unleaded gasoline blended w ith alcoho l or MTBE
( c ommon ly referred to as oxygenates) if the blended mix ture meets
the following criteria:
Blend of ga soline methanol (wood alcohol or methyl alcohol)
• Anti -k nock index m ust be 87 AKI or h igher .
• Bl end must con tain no mo re t han 3% methanol.
• Blend must contain more than 2% co-solvents.
Blend of ga soline and ethanol (grain alcohol or ethyl alcohol)
• Anti-knock index must be 87 AKI o r higher.
• Bl end must no t contain more th an 10% ethanol.

Blend of gasoline and MTBE
• Anti-knock index must be 87 AKI or higher.
• Blend must contain not more than 15% MTBE.
Seasonally adjusted gasoline
Many gasoline grades are blended to perform especially well fo r
winter or summer driving. During seasonal change-over, we suggest
that you fill up at busy gas stat ions where the seasonal adjustment is
more likely to be made in time.
0 Note
• Methano l fuels which do not meet these requirements may cause
corrosion and damage to plastic and rubber components in the fue l
system .
• Do not use fuels that fail to meet the specified criteria in this
chapter .
• If you are unab le to determine whether or not a particu lar fuel
blend meets the spec ifications, ask your serv ice station or its fuel
supplier.
• 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 responsi­
bility of Aud i and are not covered under the New Vehicle or the Em is­
sion Control System Warranties.
• If you experience a loss of fuel economy or driveab ility and perfor­
mance 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 manufacturers 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 gaso line g rades contain
substances that can cause deposits to collect on v ital engine parts,
such as fuel injectors and intake valves. A lthough most gasoline
brands include additives to keep eng ine and fuel systems clean, they
are not equally effective.
Audi recommends using TOP TIER Detergent Gasoline. For more
information on TOP TIER Detergent Gasoline, please go to the officia l
webs ite (www.toptiergas.com).
After an extended period of using inadequate fuels, carbon deposit
build-ups can rob your engine of peak performance.
0 Note
Damage or malfunction due to poor fuel quality is not covered by the
Audi New Vehicle Limited Warranty. •
Fuel tank
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 instructions see~
page 275.
You can find the fue l tank capacity of your vehicle in
Technical Data
~page 341.
The label on the inside of the fuel filler flap tells you the correct fuel
for your ve hicle. For more information about fuel specifications, see
~page 271.
Your vehicle fuel tank has an on-board refue lling vapor recovery
system. This feature helps to prevent fuel vapors from escaping from
the tank and polluting the environment wh ile you refuel your veh icle . ..,_

In order to fill the tank properly while protecting the environment,
please follow this refueling procedure carefully.
& WARNING
Under normal operating conditions, never carry additional fuel
containers in your car. Gas canisters and other containers used to
transport 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, trans­
portation and storage of such fuel containers. Make certain the
container meets industry standards (ANSI /ASTM F852 -86).
0 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. •
