Fuel and Refueling
CJ) Note
-Methanol fuels which do not meet these re­
quirements may cause corrosion and dam­
age to plastic and rubber components in the
fuel system.
- Do not use fuels that fail to meet the speci­
fied criteria in this chapter.
- If you are 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
s ibilit y 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 prob lems 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 vita l engine
parts, such as fuel injectors and intake valves. Al­
though most gasoline brands include additives to
keep eng ine and fuel systems clean, they are not
equally effective .
Audi recommends using TOP TIER Detergent Gas­
oline . For more information on TOP TIER Deter ­
gent Gasoline, please go to the official website
(www.toptiergas .com) .
After an extended period of using in adequate
fuels, built -up carbon deposits can rob your en­
g ine of peak performance .

(D Note
-Damage or malfunction due to poor fuel
quality is not covered by the Audi New Vehi­
cle Limited Warranty.
- Do not add aftermarket fuel additive prod­
ucts to your fuel tank .
Refueling
Fuel filler neck
The fuel filler neck is located on the right rear
s ide panel behind the fuel filler flap .
If the power locking system should fail , you can
still open the flap manually -for detailed instruc ­
tions see
Q page 176.
You can find the fuel tank capacity of your vehicle in
¢ page 230.
The label on the inside of the fuel fi ller flap tells
you the correct fuel for your vehicle. For more in­
formation about fuel specifications, see
¢ page 173.
Your vehicle fuel tank has an on-board refueling
vapor recovery system. This feature helps to pre­
vent fuel vapors from escaping from the tank and polluting the envi ronment while you refuel your
vehicle . In order to fill the tank properly while
protect ing the env ironment, please follow this
refueling procedure carefully.
A WARNING
Under normal operat ing conditions, never ca r­
ry additional fu el containers in your car. Gas
canisters and other containers used to trans­
port fue l can be dangerous . Such containers,
fu ll or empty, may leak and could cause a fire
in a collision. If you must transport fuel to
use for your lawn mower, snow blower, etc .,
be very careful and always observe local and
state laws regarding the use, transportation
and storage of such fuel containers . Make cer­
tai n the container meets industry standards
(ANSI/ASTM F8S2 -86) .
