Checking and Filling
-If you a re unable to determine whether or
not a particular fuel blend meets the speci
fications, ask your service station or its fuel
supplier.
- Do not use fuel for which the contents can
not be identified.
- Fuel system damage and performance prob
lems resulting from the use of fuels differ
ent from those specified a re not the respon
sibility of Audi and are not covered under
the New Vehicle or the Emission Control System Warranties.
- If you experience a loss of fuel economy or
driveability and performance 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 manufactur
ers is carbon deposit build-up caused by the type
of gasoline you use.
Although gasoline grades differ from one manu
facturer to another, they have certain things in
common. All gasoline grades contain substances
that can cause deposits to collect on vital engin e
parts, such as fuel injectors and intake valves. Al
though most gasoline brands include additives to keep engine and fuel systems clean, they are not
equally effective .
Audi recommends using TOP TI ER Dete rgent Gas
oline. For more information on TOP TIER Deter
gent Gasoline , please go to the official website
(www .toptiergas .com) .
After an extended per iod of us ing inadequate
fuels, carbon deposit build-ups can rob your
en
gine of peak performance.
(D Note
Damage or malfunction due to poor fuel qual
ity is not covered by the Audi New Vehicle Limited Warranty.

.. Insert the fuel pump nozzle all the way into the
fuel tank filler neck

off the first time, the fuel tank is full. Do not
continue fueling, or else the expansion space in
the tank will be filled with fuel.

seconds before removing it to allow the rest of
the fuel to finish dripping into the fuel tank.

Emissions control
systems
Catal ytic conve rt er
The vehicle may on ly be driven with unleaded
gasoline, otherwise the catalyt ic converter will be
destroyed.
Never drive until the tank is completely empty.
The irregular supply of f uel that results from that
can cause engine m isfires. Uncombusted fuel will
enter the exhaust system, wh ich can cause over
heat ing and damage to the catalyt ic converter .
A WARNING
The temperature of the exhaust system is
high, both when d riving and after stopping
the engine.
-
- Never touch the exhaust tail pipes once they
have become ho t. This could result in bu rns.
- Do not park your vehicle ove r flammable
materials such as g rass or leaves because
the high temperat ure of the em iss ions con
trol system co uld s tart a fire.
- Do not apply underbody p rotectant in the
exha ust system area, because this inc reases
the risk of fi re.
