Fuel supply
Using the right fuel helps keep the environ­
ment clean and prevents engine damage.
Fuel recommendation
The fuel recommended for your vehicle is un­
leaded premium
grade gasoline. Audi recom­
mends using TOP TIER Detergent Gasoline
with a minimum octane rating of 91 AKI (95
RON) . For more information on TOP TIER De­
tergent Gasoline, please go to the official
website (www.toptiergas.com).
The recommended gasoline octane rating for
your engine can also be found on a label locat­
ed on the inside of the fuel filler flap. This rat­
ing may be specified as AKI or RON.
Your vehicle may also be operated using un­ leaded regular gasoline with a minimum oc­
tane rating of 87 AKI/91 RON. However, using
87 AKI/91 RON octane fuel will slightly re­
duce engine performance.
Use unleaded gasoline only. Unleaded gaso­
line is available throughout the USA, Canada,
and in most European countries. We recom­
mend that you do not take your vehicle to
areas or countries where unleaded gasoline
may not be available.
For more information on refueling your vehi­
cle, see~
page 176.
Octane rating
Octane rating indicates a gasoline's ability to
resist engine damaging "knock" caused by
premature ignition and detonation. Therefore,
buying the correct grade of gasoline is very
important to help prevent possible engine
damage and a loss of engine performance.
Gasoline most commonly used in the United
States and Canada has the following octane ratings that can usually be found on the filler
pump:
Fuel supply and filling your fuel tank 175
- Premium Grade: 91 -96 AKI
- Regular Grade: 87 -90 AKI
Explanation of the abbreviations:
AKI = Anti Knock Index= (R+M)/2 = (RON
+MON)/2
RON= Research Octane Number
MON= Motor Octane Number.
@ Note
-Do not use any fuel with octane ratings
lower than 87 AKI or 91 RON otherwise
expensive engine damage will occur.
- Do
not use leaded gasoline. The use of
leaded gasoline will severely damage
your vehicle's catalytic converter and its
ability to control exhaust emissions.
Blended gasoline
Use of gasoline containing alcohol or
MTBE (methyl tertiary butyl ether)
You may use unleaded gasoline blended with
alcohol or MTBE (commonly referred to as
oxygenates) if the blended mixture meets the
following criteria:
Blend of gasoline methanol (wood alcohol or
methyl alcohol)
- Anti-knock index must be 87 AKI or higher.
- Blend must contain no more than 3% meth-
anol.
- Blend must contain more than 2% co-sol-
vents.
Blend of gasoline and ethanol (grain alcohol
or ethyl alcohol)
- Anti-knock index must be 87 AKI or higher.
- Blend must not contain more than 15%
ethanol.
Blend of gasoline and MTBE
- Anti-knock index must be 87 AKI or higher.
- Blend must contain not more than 15%
MTBE.

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
catalyt ic converte r.

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 .

Bulbs
Replacing bulbs
For your safety, we recommend that you have
your authorized Audi dealer replace any bulbs for you.
It is becoming increas ingly more and more
difficult to replace vehicle lig ht bulbs s ince in
many cases, other parts of the car must first
be removed before you are able to get to the bulb.
This applies especially to the light bulbs
in the front of your car which you can only
reach through the engine compartment.
Sheet meta l and bulb holders can have sharp
edges that can cause serious cuts, parts must
be correct ly taken apart and then properly put
back together to he lp prevent breakage of
parts and long term damage from water that
can enter housings that have not been proper­
ly resealed.
For your safety, we recommend that you have
your authori zed Audi dea ler replace any bulbs
for you, since your dealer has the proper tools,
the correct bulbs and the expertise.
Gas discharge lamps (Xenon lights ):
Due to the high e lectr ica l voltage, have the
bulbs replaced by a qualified technician.
Headlights with Xenon light are identified by
the high voltage st icker.
A WARNING "--
Changing Xenon lamps without the neces-
sary equipment can cause serious persona l
injury.
- Bulbs are pressurized and can explode
when being changed. Potential risk of in­
jury!
- On veh icles equipped with gas discharge
bulbs (Xenon light) life-threatening inju­
ries can result from improper handling of
the high-voltage portions of such lamps!
- Only your authorized Audi dealer or qualified workshop should change the
bu lbs in gas discharge lamps. There are
pa rts with sharp edges on the openings
and on the bulb holders that can cause
serious cuts. If you are uncertain about
what to do, have the work performed by
an authorized Audi dealer or qualified
workshop. Serious personal injury may
result from improperly performed work.
@ Tips
-If you still prefer to replace the light
bulbs yourself, be aware that the engine ..,.
