Fuel supply
Using the right fuel helps keep the environment
clean and prevents engine damage.
Fuel recommendation
The fuel recommended for your vehicle is unlead­
ed premium
grade gasoline. Audi recommends
using TOP TIER Detergent Gasoline with a mini­ mum octane rating of 91 AKI (95 RON). For more
information on TOP TIER Detergent Gasoline,
please go to the official website
(www.toptiergas.com).
The recommended gasoline octane rating for
your eng ine can also be found on a label located
on the ins ide of the fuel filler flap. This rating
may be specified as AKI or RON.
Your vehicle may also be operated using unlead­
ed regular gasoline with a minimum octane rat­ ing of 87 AKl/91 RON . However, using 87 AKl/91
RON octane fue l will s lightly reduce eng ine per­
formance.
Use unleaded gasoline only. Unleaded gasoline
is available throughout the USA, Canada, and in
most European countries. We recommend that
you do not take your vehicle to areas or countries
where unleaded gasoline may not be available.
For more informat ion on refueling your vehicle,
see
~page 188.
Octane rating
Octane rating ind icates a gasoline's ability to re­
sist engine damaging "knock" caused by prema­
ture ignition and detonation. Therefore, buying
the correct grade of gasoline is very important to
he lp prevent possible eng ine damage and a loss
of engine performance.
Gasoline most commonly used in the United
States and Canada has the following octane rat­
i n gs that can usually be found on the filler pump:
- Premium Grade : 91 - 96 AKI
- Regular Grade: 87 -90 AKI
186
Explanation of the abbreviations:
AKI= Anti Knock Index= (R+M)/2 = (RON+MON)/
2
RON = Re search Octane Number
MON= Motor Octane Number.
CJ) Note
- Do not use any fuel with octane ratings low­
er than 87 AKI or 91 RON otherwise expen­
sive engine damage will occur.
- Do
not use leaded gasoline. The use of lead­
ed gasoline will severely damage your vehi­
cle's catalytic converter and its ability to
control exhaust emissions.
Blended gasoline
Use of gasoline containing alcohol or MTBE
( methyl tertiary butyl ether)
You may use unleaded gasoline blended with a l­
cohol or MTBE (commonly referred to as oxygen­
ates) if the blended mixture mee ts the following
criteria:
Blend of gasoline methanol (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 than 2% co-solvents.
Blend of gasoline and ethanol (grain alcohol or
ethyl alcohol)
-Anti-knock index must be 87 AKI or h igher.
- Blend must not contain more than 1S% etha-
nol.
- Veh icles with flex ible fuel engine: blend must
not contain more than 85% 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 es­
pecially well for winter or summer dr iv ing . Dur-
i ng seasonal change-over, we suggest that you ""

Operating your vehicle
outside the U.S.A. or
Canada
Government regulations in the United States and
Canada require that automobiles meet specific
emission regulations and safety standards.
Therefore, vehicles built for the U.S.A. and Cana­
da differ from vehicles sold in other countr ies.
If you plan to take your veh icle outside the conti­
nenta l limits of the United States or Canada,
there is the possibility that:
- unleaded fuels for vehicles with catalytic con­
verter may not be available;
- fuel may have a considerably lower octane rat ­
ing . Improper fuel may cause engine damage;
- serv ice may be inadequate due to lack of proper
serv ice facilities , tools or testing equipment;
- r eplacement parts may not be readily available .
- Nav igat ion systems for vehicles built for the
U.S.A. and Canada will not necessar ily work in
Europe, and may not work in othe r countries
outside of North America.

Maintenance
General '
Your vehicle has been designed to help keep
maintenance requirements to a minimum. How­
ever, a certain amount of regular maintenance is
still necessary to assure your veh icle's safety,
economy and reliability. For deta iled vehicle
maintenance consult your Warranty & Mainte­
nance booklet .
Under difficult operating conditions, for exam­
ple at extremely low outs ide temperatures, in
very dusty regions, when towing a trailer very fre­
quently , etc., some service work should be per­
formed between the intervals specified. This ap­
plies particularly to:
- oil changes, and
- cleaning or replacing the air filter .

@) For the sake of the environment
By regularly maintaining your vehicle, you
help make sure that emission standards are
maintained, thus minimizing adverse effects
on the environment.
Important considerations for you and your
vehicle
