websi te (www. topt iergas .com) .
T he re commended gasoline octa ne rating for
your engine can also be fo und o n a label loc at
ed on the ins ide of the fue l filler flap . This ra t
in g may be specified as AK I or RO N.
Your veh icle may also be operated u sing un
l eaded regular g asoline with a minimum oc
tane rating of 87 AKI/91 RO N. Howeve r, using
87 AKI/91 RON octa ne fue l wi ll slightly re
d uce eng ine perfo rmance .
Use unleaded ga soline only. Unleaded g aso
li ne is available th rougho ut the USA, Canada,
a nd i n most E uro pean countries . We recom
mend that you do not ta ke yo ur vehicle to
areas or countries where unleaded gasoline
may not be ava ilable.
F or mo re informat io n on refue ling your ve hi

page 225.
Octane rating
Octane rating ind icates a gaso line's ability to
r es ist engine dam ag in g "kno ck" cau sed b y
premature ign ition and detona tion. Therefore,
b uy ing the correct grade of gaso line is very
important to he lp prevent possible engine
damage and a loss o f engine performance.
G asoline mos t commonly used in the Unite d
States and Canada has the following octane r
atings t hat can usu a lly be found on the fi ller
pump:
- Premium Gr ade: 91 -9 6 A KI
- Regular Grade : 87 -90 AKI
Explanation of the abbreviations:
AKI = Anti Knock In d ex = (R+M) /2 = (RO N
+ MON)/2
R ON= Resea rch Octane Number
MON = Motor Octane Num ber.
(D Note
- Do not use a ny fue l w it h octane rat ings
lower tha n 87 A KI or 91 RO N othe rwise
e xpensive engine damage w ill occur.
- Do
not use leaded gasoline. The use of
leaded gasoline w ill severely damage

Gasoline additives
App lies to vehicles: with gasoline engine
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 differ from one
manufacturer to another , they have certa in
things in common. All gasoli ne g rades contain
substances that can ca use depos its to co llec t
on vi tal engine parts, suc h as fu el injectors
and inta ke valves . Although most gasoline
b rands include addi tive s to kee p eng ine and
f u e l sys tems clean, they are no t eq ually e ffec
tive.

Diesel fuel
Applies to vehicles: wit h diese l eng ine
Always use ULSD (Ultra Low Sulfur Diesel) sul
fur content 15 ppm or less .
The ULSD (Ultra Low Sulfur Diese l) meets the
ASTM-D-97S (grade 2).
Die sel fuel with a higher con cent ration than
ULSD-Diesel No. 2 ASTM D9 75 and Bio-die
sel with a higher concentrat ion than 5
% like
Bl 1, B20 or B100 are strictly prohib ited.
Se rv ice stat ion fue l pum ps a re labe led with
the correct fuel information for easy recogn i
t ion by t he user. If the d iesel fuel pump is not
l abeled ask the station operator what fuel is
being dispensed before filling up you r vehicle.
Se rv ice stat ions offering Diese l fue l are gener
ally located on t ruck routes or major high
ways. Directories of Diesel f uel stat io ns are
u sua lly available at D iese l fuel stations .
Some states in the USA req uire permits to
purchase Diesel fuel. Check with your State
Motor Vehicle Department .
Diesel f uel may not be ava ila bl e outside t he
U SA and Canada. Be s ure to check before trav
eling to other countries.
Winter operation
At tempe ratu res be low 20° F (- 7° C), Diesel
fuel No. 2 loses its fluidity due to wax sepa ra
t ion, w hich may clog the fue l fi lter or tank fi l
ter and keep the eng ine from runn ing .
T o he lp the filte r from bei ng clogged by wax,
t h e f ue l fi lter in yo ur vehicle is automatically
preheate d. Pre heat ing t he f uel fi lter makes
operation of your vehicle poss ible with D iese l
fuel No. 2 down to -10° F (-24° C) .
If you expect temperatures below 5° F
( - 15° C) ask your fue l dea ler whether thei r
Diesel f uel N o. 2 is s uff icient ly w interized for
the prevailing and expected temperatures.
If not winter ized o r ins uff ic ient ly w interized
Diesel f uel has already thickened to t he extent
t h at the engine wi ll not start, warm the vehi -
cle up by leav ing it in a heated garage.

When activating the central locking, the fuel
filler flap is automatically unlocked or locked.
Refuel the vehicle with the ign ition turned
off .
Tak ing th e fu el cap off
• Press the Left side of the fue l filler flap to
open it ¢
fig. 190 -arrow-.
.. Unscrew fuel cap counter-clockwise and
hang it on the fuel filler flap ¢
fig. 191.
.. Check the Label on the inside of the fuel fill
er flap to determine if the vehicle must be
fueled with gasoline or diesel fuel.
Ref uelling pr ocedu re
.. Insert the fue l no zzle 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
tan k is full .
Putting the fu el cap b ack o n
• After f illing your tank, twist the fuel cap
clockwise as far as it will go .
.. Close the fue l filler flap.
T o avoid fuel spill ing o r evaporating from the
fuel tank always close fuel cap p roperly and
completely . An improperly closed fuel filler
cap may a lso ca use the
MIL Lamp ¢ page 26
to come on (on ly vehicles with gasoline en
gine).
A WARNING
-Improper refueling or handling of fuel can
cause fire, explosion and severe burns .
- Fuel is highly flammable and can cause
severe bu rns 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
fuel to spray out of filler neck or to over
flow. Fue l spray and overflowing fuel can
cause a fire .
- Never use a cellular telephone while re
fue ling. The electromagnet ic rad iat ion
can cause spa rks that can ignite f uel va
pors and cause a fire .
- Never get back into your vehicle whi le re
fue ling.
If in exceptional circ umstances
you must get back in your vehicle while
refueling, make certain that you close
the door and touch metal to discharge
static e lectricity before touching the fill
er nozzle again . Static e lectr icity can
cause sparks that can ignite fuel vapors
released du ring refueling .
- Never smoke or have an open flame any
where in or near your vehicle when refu eling or filling a portable fuel conta iner.
- For your safety, we strongly recommend
that you do not travel with a portable
fuel conta iner in your vehicle . The con
tainer, fu ll o r empty may leak and could
cause a fire, especially i n a c rash.
- If , under exceptional c ircumstances, you
must transport a portab le fuel conta iner,
p lease observe the following: .,.
-Never f ill 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 bu ild 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 fill ing 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
h ig hly 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
F852-86).
(D Note
If any fuel has spilled onto the car, it
should be removed immediate ly 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 fue l because fuel may spill out. In
addition, the expansion space in the fuel
tank will be fi lled -causing the fue l to
overflow when it becomes warm and pol
lute the environment.
@ Tips
-Running your engine while refuelling
may cause vapors to escape or even
cause fuel to spill out of the tank. This
would then shut off the fuel nozzle be
fore the tank is full.
Fuel su ppl y and filling your fuel ta nk 22 7
-Do not refuel your vehicle with the igni
tion turned on . The fuel gauge may oth
erwise not indicate the correct fuel level
after refuelling.
- Diesel vehicles* are equipped with a die
sel misfueling protector. It allows the
vehicle to be fueled only with a diesel
fuel pump nozzle. A worn or damaged nozzle or a nozzle that is too small may
not be able to open the diesel misfueling
protector. If this is the case, try tu rning
the nozzle before insert ing it in the fuel
filler neck, use a different fuel pump or
see your authorized Audi dea ler
or au
thorized repair facility for assistance.
- 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.
