Many gasoline grades are blended to perform especia lly we ll for
winter or summer drivi ng . Dur ing seasona l change -over, we suggest
that you fil l up at busy gas stations where the seasonal adjustment
is more likely to be made in time .
0 Note
• Methanol fuels which do not meet these requirements may
cause corrosion and damage to plastic and rubber components in
the fue l system.
• Do not use fuels that fail to meet the specified criteria in this
chapter .
• If you are unable to determine whether or not a particu lar fuel
b lend meets the specifications, ask your service station or its fuel
supplier.
• Do not use fuel for w hich the contents ca nnot be identified.
• Fue l system damage and performance problems resulting from
t he use of fuels different fro m those specified are no t the responsi ­
bility of Audi and are not covered under the New Vehicle or the
Em ission Control System Warranties .
• If you experience a loss of fue l economy or driveabi lity and
performa nce problems due to the use of o ne of these fuel blends,
we recommend that you switch to unblended fuel. •
Gasoline additives
A major concern among many auto manufacturers is carbon
depos it build-up caused by the type of gasoline you use.
A lthough gasoline grades differ from one manufacturer to another,
they have certain things in common. All gaso line grades contain
substances that can cause deposits to co llect on vital engine parts,
such as fue l injectors and intake valves. A lthough most gaso line
brands include additives to keep engine and fue l systems clean,
they are not equal ly effective .
Audi reco mmends using TOP TIER De tergen t Gasoline. For more
information on TOP T IER Detergent Gasoline, please go to the offi ­
cia l website (www.toptie rgas .com).
After an extended period of using inadequate fuels, built-up carbon
deposits can rob your engine of peak performance .

Damage or malfunction due to poor fuel qua lity is not covered by
the Aud i New Veh ic le Limited Warranty. •

Fuel supply and filling your fuel tank
Taking the fuel cap off
- To open the fuel filler flap, pull the button~ page 269,
fig. 200.
- Unscrew fuel filler cap counter-clockwise and hang it on the fuel filler flap.
Refuelling procedure
- Insert the fuel nozzle from the gasoline pump into the
fuel filler neck as far as it will go.
- Select a medium refuelling rate so that the nozzle
switches off automatically when the tank is full.
Putting the fuel cap back on
- After filling your tank, twist the fuel filler cap clockwise
until you hear a definite click.
- Close the fuel filler flap.
To avoid fuel spilling or evaporating from the fuel tank always close
fuel filler cap properly and completely. An improperly closed fuel
filler cap may also cause the MIL lamp => page 27to come on.
& WARNING
Improper refueling or handling of fuel can cause fire, explosion
and severe burns .
• Fuel is highly flammable and can cause severe burns and other
injuries.
• Failure to shut the engine off while refueling and/or to insert
the pump nozzle fully into the car's filler neck could cause fuel
overflow and fuel spray. Fuel spray and overflowing fuel are
dangerous because they can cause fire or serious injury.
& WARNING (continued)
• Never use a cellular telephone while refueling. The electromag­
netic radiation can cause sparks that can ignite fuel vapors and
cause a fire .
• Never get back into your vehicle while refueling. If in excep­
tional circumstances you must get back in your vehicle while refu­
eling, make certain that you close the door and touch metal to
discharge static electricity before touching the filler nozzle again .
Static electricity can cause sparks that can ignite fuel vapors
released during refueling .
• Never smoke or have an open flame anywhere in or near your
vehicle when refueling or filling a portable fuel container.
• For your safety, we strongly recommend that you do not travel
with a portable fuel container in your vehicle. The container, full or
empty may leak and could cause a fire, especially in a crash.
• If, under exceptional circumstances, you must transport a
portable fuel container, please observe the following:
- Never fill a portable fuel container while it is anywhere in or
on the vehicle (for example, in the luggage compartment, or on
the trunk). Static electricity can build up while filling and can
ignite fuel vapors causing a fire.
- Always place a portable fuel container on the ground before
filling.
- Always keep the filler nozzle completely inside the portable container before and during filling.
- If filling a portable container made of metal, the filler nozzle must always be in contact with the container. This will help
prevent static electricity from discharging and cause a fire.
- Never spill fuel inside the vehicle or luggage compartment .
Fuel vapors are highly flammable.
- Always observe local and state/provincial laws regarding the
use, storage and transportation of fuel containers
