Using the right fuel helps keep the environment
clean and prevents engine damage.
Fuel re co mm en da tion
The fuel recommended for your vehicle is unl ead­
e d prem ium
grade gaso line. 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 engine 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 gasol ine with a minimum octane rat ­
ing of 87 AKl/91 RON. However, using 87 AKI/
91 RON octane fue l wi ll sli ght ly reduce engine
pe rformance.
U se un leade d ga solin e only . Unleaded gasoline
is available throughout the USA, Canada, and in
most European countries. We recommend that
you do not ta ke you r vehicle to areas or countr ies
where unleaded gasoline may no t be ava ilable.
For more informat ion on refueling your veh icle,
see
¢page 192.
Octan e rat ing
Octane rating indicates 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 eng ine performance.
Gasoline most commonly used in the Un ited
States and Canada has the following octane rat­
i n gs that ca n usually be found on the filler pump:
- Prem ium Grade : 91 - 96 AKI
190
- Regular Grade: 87 -90 AKI
Explanation of the abb reviations:
AKI = Anti Knock Index = (R +M)/2 = (RON+MON)/
2
RON= Research Octane Number
MON = Motor Octane Number.
{[) Note
-Do not use any fue l w ith o ctane rat ings low­
er than 87 AKI or 91 RON otherwise expen­
sive engine damage w ill occur .
- Do
not use leaded gasoline. The use of lead­
ed gasoline will severely damage your veh i­
cle's catalytic converter and its abi lity to
control exha ust em issions.
Blended gasoline
App lies to vehicles: wit h gaso line e ngi ne
U se of g aso lin e cont aining alcohol or MTBE
( meth yl tert iary butyl ethe r)
You may use unleaded gasoline blended with al­
cohol or MTB E (commonly referred to as oxygen­
ates) if the ble nded mixture meets the following
criteria:
Blend of gasoline methano l (wood alcohol or
m eth yl alcoho l)
-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 ga solin e and ethan ol (grain alcoh ol or
ethyl alcohol )
- Anti-knock index must be 87 AKI or h igher.
- Blend must not conta in more than 15% etha-
nol.
Blend of ga soline a nd M TBE
- Anti-knock index must be 87 AK I or h igher.
- Blend must contain not more tha n 1S % MTB E.
S eas onall y adjust ed gasoline
Many gasoline grades are blended to perform es­
pecially well for winter or summer dr iv ing . Dur-

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 North America .

Maintenance
General '
Your vehicle has been designed to help keep
maintenance requirements to a m inimum. 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 veh icle, you
help make sure that emission 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 comp lexity of
