Checking and Filling
Fuel supply
Applies to vehicles: with gasoline engine
Using the right fuel helps keep the environ­
ment clean and prevents engine damage.
Fuel recommendation
The fuel recommended for your vehicle is un­
leaded premium
grade gasoline . Audi recom­
mends using TOP TIER Detergent Gasoline
with a minimum octane rating of 91 AKI (95
RON). For more information on TOP TIER De­
tergent Gasoline, please go to the off icia l
website (www.toptiergas.com).
The recommended gasoline octane rating for
your engine can a lso be found on a label locat­
ed on the inside of the fuel filler flap. This rat­
ing may be specified as AKI or RON.
Your vehicle may also be operated using un­ leaded regular gasoline with a minimum oc­
tane rating of
87 AKI/91 RON. However, using
87 AKI/91 RON octane fuel w ill slightly re­
duce eng ine performance.
Use unleaded gasoline only. Unleaded gaso­
line is available throughout the USA, Canada,
and in most European countries. We recom­
mend that you do not take your vehicle to
areas or countries where unleaded gasoline
may not be ava ilable .
For more informat ion on refueling your vehi­
cle, see
c:> page 211 .
Octane rating
Octane rating indicates a gasoline's ability to
res ist engine damaging "knock" caused by
premature ign ition and detonation. Therefore,
buying the correct grade of gasoline is very
important to help prevent possible engine
damage and a loss of engine performance .
Gasoline most commonly used in the United
States and Canada has the following octane
ratings that can usually be found on the filler
pump:
- Prem ium Grade : 91- 96 AKI -
Regular Grade:
87 -90 AKI
E xplanation of the abbreviations:
AK I=
Anti Knock Index = (R +M)/2 = (RON
+MON)/2
RON= Research Octane Number
MON = Motor Octane Number.
(D Note
- Do not use any fuel w ith octane rat ings
lower than
87 AK I or 91 RON otherwise
expensive engine damage will occur .
- Do
not us e leaded gasoline. The use of
leaded gasoline w ill severely damage
your vehicle's catalytic converter and its
ability to control exhaust emissions.
Blended gasoline
Applies to vehicles: with gasoline engine
Use of gasoline containing alcohol or
MTBE (methyl tertiary butyl ether)
You may use unleaded gasoline blended with
alcohol or MTBE (commonly referred to as
oxygenates) if the blended mixture meets the
follow ing criteria:
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% 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 co nta in more than 15%
ethanol.
Blend of gasoline and MTBE
-Anti-knock index must be 87 AKI or higher.
- Blend must contain not more than 15%
MTBE.

Operating your vehicle
outside the U.S.A. or
Canada
Government regu lations in the United States
and Canada require that automobiles meet
specific emission regulations and safety
standards. Therefore, veh icles built for the
U.S.A . and Canada differ from vehicles sold in
other countries .
If you p lan to take your vehicle outside the
continental limits of the United States or Can­
ada, there is the possibility that:
- unleaded fuels for vehicles with cata lytic
converter may not be available;
- fuel may have a considerably lowe r octane
rating. Improper fuel may cause engine
damage ;
- service may be inadequate due to lack of
proper service facilities, tools or testing
equipment ;
- replacement pa rts may not be readily availa­
ble.
- Navigation systems for vehicles built for the
U.S.A. and Canada will not necessar ily work
in Europe, and may not work in other coun­
tries outside North America .
(D Note
Audi cannot be responsible for mechanical
damage that could result from inadequate
fuel, service or parts availability.

Under difficult operating conditions, for ex­
ample at extremely low outside temperatures,
i n very dusty regions , when towing a trailer
very frequently, etc., some service work
should be performed between the intervals
specified. This applies particularly to:
- oil changes, and
- cleaning or replacing the air filter .
