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 are 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 engine
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 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 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.

Refueling
'
Fuel filler neck
The fuel filler neck is located on the right rear
side 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
~ page 237.
You can find the fuel tank capacity of your vehicle
in
~ page 301.
The label on the inside of the fuel filler flap tells
you the correct fuel for your vehicle. For more in-
formation about fuel specifications, see
~ page 233.
Your vehicle fuel tank has an on board refuelling
vapor recovery system. This feature helps to pre-
vent fuel vapors from escaping from the tank and
polluting the environment while you refuel your
vehicle. In order to fill the tank properly while
protecting the environment, please follow this
refueling procedure carefully.
.8, WARNING
Under normal operating conditions, never car-
ry additional fuel containers in your car. Gas
canisters and other containers used to trans-
port fuel can be dangerous. Such containers,
full 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-
tain the container meets industry standards
(ANSI/ASTM F852 - 86).
CI) Note
Never drive your vehicle until the fuel tank is
completely empty. The irregular supply of
fuel can cause misfiring. Gasoline could enter
the exhaust system and damage the catalytic
converter.
