& WARNING
-Always observe the wa rning in
¢
page 179, before opening the hood
and checking the engine coolant level.
- Never open the engine hood if you see or
hear steam, or if you see engine coolant
dripping from the engine compartment.
You could burn yourself. Let the engine cool off first so that you cannot hear or
see any steam or engine coolant.
(D Note
- Mounting additional lights or accessories
in front of the air inlets reduces the cool­
i ng effect of the rad iator. At h igh outside
temperatures or high eng ine load, the
engine could overheat.
- The front spo iler has been designed to
proper ly distr ib ute the cooling air when
the veh icle is moving.
If the spoiler is
damaged, this cou ld redu ce the cooling
effect and the engine co uld then over­
heat. Ask yo ur autho rized Aud i de aler f or
assistance.
Tachometer (engine rev counter)
The tachometer indicates the engine RPM
(revolutions per minutes).
If engine R PM drops be low 1,500, you should
downshift to the next lower gear. The red area
at the e nd of the sca le ind icates maximum
permissible engine RPM after the break- in pe­
riod. Before reaching this area, move these­
l ector lever to position D/S or ease your foot
off the accelerator peda l.
(D Note
The tachometer needle@¢ page 10,
fig. 3 sho uld only briefly be in the red
zone: you could damage your engine! The
beg inning of the red zone varies depend­
ing on the engine.

176 Fuel suppl y and fillin g your fu el tank
Many gaso line grades are blended to perform
especially we ll for winter or summer driving.
During seasonal change-over, we suggest that
you fill up at busy gas stations where the sea­ sonal adjustment is more likely to be made in
time.
@ Note
- Methanol fuels which do not meet these
requirements may cause corrosion and
damage to plastic and rubber compo ­
nents in the fuel system.
- Do not use fuels that fail to meet the
spec ified criter ia in this chapter .
- If you are unable to determine whether
or not a particular fuel blend meets the
spec ificat ions, ask your service station o r
i ts fuel supplier .
- Do not use fuel for wh ich the contents
cannot be identified .
- Fuel system damage and performance
problems resulting from the use of fuels
different from those specified are not
the respons ibility of Audi and are not
covered under the New Ve hicle or the
Emission Control System Warranties.
- If you experience a loss of fue l economy
or driveabil ity and performance prob­
l ems due to the use o f one of these fuel
blends, we recommend that you switch
to unblended fuel.
Gasoline additives
A major concern among many auto manufac­
turers is carbon deposit build-up caused by
the type of gasoline you use .
A lthough gasoline grades diffe r from one
manufac turer to another, they have certa in
things in common. All gasoline grades contain
substances that can cause depos its to collect
on vital engine parts, such as fuel injectors
and intake valves . Although most gasoline
b rands include additives to keep eng ine and
fuel systems clean , they are not eq ua lly effec­
tive. Audi recommends using
TOP TIER Detergent
Gasoline . For more information on TOP TIER
Detergent Gasoline, please go to the official
website (www.toptiergas .com) .
After an extended period o f using inadeq uate
fuels, built-up carbon deposits can rob your engine of peak performance.
(D Note
- Damage or malfunction due to poor fuel
quality is not covered by the Audi New
Vehicle Limited Warranty .
- Do not add afte rmarket fuel additive
produc ts to your f uel tank .
Fuel tank
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
instruct ions see o page 178.
You can find the fuel tank capacity of your ve­
hicle in
o page 235 .
The label on the inside of the f uel fi ller flap
te lls you the correct fue l for your vehicle. For
more information about fue l specifications,
see
c:;, poge 175.
Your vehicle fue l tank has an on -board refuel­
ing vapor recovery system . This feature helps
to prevent fuel vapors from escaping from the
tank and pollut ing the environment while you
refuel your vehicle. In order to fill the tank
properly while protecting the environment,
please follow this refueling procedure careful­
ly.
.&_ WARNING
Under normal operating cond itions, never
carry addit ional fue l conta iners in your car .
Gas canisters and other conta iners used to
transport f uel can be dangero us. Such con-
tainers, fu ll or empty, may leak and could ..,.

transport fue l to use for yo ur lawn mowe r,
snow blower, etc., be very careful and al­
ways observe local and state laws regard­
ing the use, transportat ion and storage of
such fuel containers . Make certain the con­
t ainer meets industry standards (ANSI/
AS TM F 852 -86).
(D Note
Never drive yo ur vehicle unt il the fuel tank
is completely empty . The irregular supp ly
of fuel can cause misfi ring. Gasoline could
enter the exhaust system and damage the

Refueling procedure
• Insert the fuel nozzle from the gasoline
pump into the fuel fi ller neck as far as it wi ll
go .
• Select a medium refueling rate so that the
no zz le switches off automatically when the
tank i s full .
Putting th e fuel cap bac k on
• After filling your tank, twist the fuel cap
clockw ise as far as it will go .
• Close the fue l filler flap.
T o avoid fuel spill ing or evaporating from the
fuel tank always close fuel cap properly and
completely . An improper ly closed fuel filler
cap may also cause the MIL lamp ¢
page 26
to come on.
A WARNING
Improper refue ling or handling of fuel can
cause fire, explosion and severe burns.
- Fuel is highly flammable and can cause
severe burns and other injur ies .
- Failure to shut the engine off while refu­
eling and/or to insert the pump nozzle
fully into the fuel filler neck could cause
fue l to spray out of filler neck or to over­
flow. Fue l spray and overflowing fuel can
cause a fire .
- Never use a ce llu lar telephone while re­
fue ling. The electromagnet ic rad iation
can cause sparks that can ignite f uel va­
pors and cause a fire.
- Never get back into yo ur vehicle while re­
fuel ing.
If in excep tional circumstances
you must get back in your vehicle while refueling, make certain that you close
the door and touch metal to discharge static electricity before touching the fill­
er nozzle again . Static electr icity can
cause sparks that can ignite fuel vapors
released during refueling.
- Never smoke or have an open f lame any­
where in or near your veh icle when refu ­
eling or filling a portab le fuel conta iner .
- For your safety, we strongly recommend
that you do not t ravel with a portable

1 78 Fuel supply and filling your fuel tank
fuel container in your vehicle. The con­
tainer, 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 compart­
ment, or on the trunk). Static electrici­
ty can build up while filling and can ig­ nite fuel vapors causing a fire .
- Always place a portable fuel container
on the ground before filling.
- Always keep the filler nozzle complete­
ly 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 dis­
charging and cause a fire.
- Never spill fuel inside the vehicle or
luggage compartment. Fuel vapors are
highly flammable.
- Always observe local and state/provin­
cial laws regarding the use, storage
and transportation of fuel containers .
- Make certain the fuel container meets
industry standards (ANSI/ ASTM
F8S2 -86) .
d) Note
If any fuel has spilled onto the car, it
should be removed immediately to prevent
damage to the paint .
@ For the sake of the environment
As soon as the correctly operated nozzle
switches off automatically for the first
time, the tank is full. Do not try to add more fuel because fuel may spill out. In
addition, the expansion space in the fuel
tank will be filled -causing the fuel to
overflow when it becomes warm and pol­
lute the environment.
(D Tips
- Running your engine while refueling may
cause vapors to escape or even cause
fuel to spill out of the tank. This would
then shut off the fuel nozzle before the
tank is full .
- Do not refuel your vehicle with the igni­
tion turned on. The fuel gauge may oth­ erwise not indicate the correct fuel level
after refueling .
- The fuel filler flap of your vehicle is not
locked when you lock the vehicle from
the inside .
Unlocking the fuel filler flap
by hand
You can open the fuel filler flap by hand if the
power locking system should fail.

180 Checking and filling
coolant can be seen or heard before
carefully opening the hood.
- Keep children away from the engine com­
partment.
- Never spill fluids on hot engine compo­
nents. They can cause a fire.
- Never touch the radiator fan. The auxili­ ary electric fan is temperature controlled
and can switch on suddenly.
- Never open the coolant reservoir cap
when the engine is still warm. The cool­
ant system is pressurized and hot cool­
ant could spray out .
- Protect your face, hands and arm from
steam or hot engine coolant by placing a
thick rag over the cap when you open the
coolant reservoir .
- Do not remove the engine cover under
any circumstances. This increases the
risk of burns.
- If work on the fuel system or the electri­
cal system is necessary:
- Always disconnect the battery .
- Never smoke or work near heaters or
open flames. Fluids in the engine com­
partment could start a fire.
- Keep an approved fire extinguisher im­
mediately available.
- To avoid electrical shock and personal in­
jury while the engine is running or being
started, never touch:
- Ignition cables
- Other components of the high voltage
electronic ignition system.
- If you must perform a check or repair
with the engine running:
- First, fully apply the parking brake,
move selector lever of automatic trans­
mission to "P" (Park) .
-Always use extreme caution to prevent
clothing, jewelry, or long hair from get- ting caught in the
radiator fan, V-belts
or other moving parts, or from contact­
ing hot parts. Tie back hair before
starting, and do not wear clothing that
will hang or droop into the engine .
- Minimize exposure to emission and
chemical hazards
