Fuel supply Using the right fuel helps keep the environment clean and
prevents engine damage.
Fuel r ecomm end ati on
The fuel recommended for your vehic le is unl eade d prem ium grade
gaso line . See also ~
page 363, "Data". Audi recommends using TOP
T IER Detergent Gasoline with a minimum octane rating of 91 AKI (95
RON). For more information on TOP TIER Detergent Gaso line, please
go to the official website (www.toptiergas .com).
The recommended gasoline octane rating for your engine can also be found on a label located on the inside of the fuel fille r flap. This
rating may be specified as AK I or RON .
Your vehic le may also be operated us ing unleaded regular gasoline
with a minimum octane rating of 87 AKl/91 RON . However, using 87
AKl/9 1 RON octane fuel will slightly reduce engine performance.
Use unle ad ed ga so line only . Unleaded gaso line is avai lable
throughout the USA, Canada, and in most European countries. We
recommend that you do not take your vehicle to areas or countr ies
where un leaded gasoline may not be available .
For more information on refueling your vehicle, see~
page 292.
Octane ra tin g
Octane rating indicates a gaso line's ability to resist engine
damaging "knock" caused by premature ignition and detonation.
Therefore, buying the correct grade of gaso line is very important to
help prevent possible engine damage and a loss of engine perfor ­
mance.
F ue l supply and fillin g you r fu el tank
Gasoline most common ly used in the United States and Canada has
the following octane ratings that can usua lly be found on the filler
pump:
• Premium Grade : 91 -96 AKI
• Regular Grade: 87 -90 AKI
Explanation of the abbreviations:
AKI = Anti Knock Index= (R +M)/2 = (RON +MON)/2
RON = Research Octane Number
MON
= M otor Octane Number .
0 Note
• Do not use any fue l with octane ratings lower than 87 AKI or 91
RON otherwise expensive engine damage will occur .
• Do
not use leaded gasoline. The use of leaded gasoline w ill
severe ly damage your vehicle's catalytic converter and its abi lity to
control exhaust emissions. •
Blended gasoline
Use of g aso line containing alco hol or M TB E ( meth yl
t er tiary butyl e ther )
You may use unleaded gasoline blended with alcohol or MTBE
(commonly referred to as oxygenates) if the blended mixture meets
the follow ing criteria:
Bl end of g asoline m eth anol (wood al coho l or methyl alc oh ol)
• Anti-knock index must be 87 AKI or higher .
• Blend must contain no more than 3% methanol.
• Blend must contain more than 2% co-solvents.

standards. Therefore, vehicles built for the U.S .A. and Canada differ
from vehicles sold in other countries.
If you plan to take your vehicle outside the continental limits of the
United States or Canada, there is the possibility that
• unleaded fuels for vehicles with catalytic converter may not be
available;
• fuel may have a considerably lower octane rating. Improper fuel
may cause engine damage;
• service may be inadequate due to lack of proper service facilities,
tools or testing equipment;
• replacement parts may not be readily available .
• Navigation systems for vehicles built for the U.S.A. and Canada
will not necessarily work in Europe , and may not work in other coun­
tries outside of North America.
0 Note
Audi cannot be responsible for mechanical damage that could
result from inadequate fuel , service or parts availability .•

Maintenance
General
Your vehicle has been designed to help keep maintenance require­
ments to a minimum. However, a certain amount of regular mainte­
nance is still necessary to assure your vehicle 's safety, economy and
reliability. For detailed vehicle maintenance consult your Mainte­
nance & Warranty booklet .
Under difficult operating conditions, for example at extremely low
outside temperatures, in 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.
~ For the sake of the environment
By regularly maintaining your vehicle, you help make sure that emis ­
sion standards are maintained, thus minimizing adverse effects on
the environment. •
Important considerations for you and your
vehicle
The increasing use of electronics, sophisticated fuel injection and
emission control systems, and the generally increasing technical
complexity of today's automobiles, have steadily reduced the scope
of maintenance and repairs which can be carried out by vehicle
owners. Also, safety and environmental concerns place very strict
limits on the nature of repairs and adjustments to engine and trans­
mission parts which an owner can perform.
Maintenance, adjustments and repairs usually require special tools,
testing devices and other equipment available to specially trained .,_
