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 250.
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

Seasonally adjusted gasoline
Many gasoline grades are blended to perform
espec ially we ll for winter or summer driving.
During seasonal change-over, we suggest that
you fill up at busy gas stat ions where the sea
sonal adjustment is more likely to be made in
time .
(D 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 fue ls that fail to meet the
specified criter ia in this chapter.
- If you are unable to determine whether
or not a particular fue l blend meets the
specifications, ask your service station or
its fuel supp lier.
- Do not use fuel for which the contents
cannot be identified.
- Fuel system damage and performance
problems resulting from the use of fuels
different from those specified are not
the responsibility 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 prob l ems due to the use of one of these fuel
blends, we recommend that you switch
to unblended fuel.
Gasoline additives
Applies to vehicles : wit h gasoli ne e ng in e
A majo r concern among many auto manufac
ture rs is carbon deposit build-up caused by
the type of gasoline you use.
Although gasoline grades differ from one manufacturer to another , they have certain
things in common. All gasoline g rades contain
substances that can cause deposits to collect
on vital engine parts, such as fuel injectors
and intake valves. Although most gasoline
Fuel supply and filling your fuel tank 249
brands include additives to keep engine and
fuel systems clean, they are not equally effec
tive .
Audi recommends using TOP TIER Detergent
Gasoline . For more information on TOP TIER
Detergent Gasoline, please go to the official
webs ite (www.toptiergas.com).
After an extended per iod of using inadeq uate
fuels, carbon deposit build-ups can rob your
engine of peak performance.
CD Note
Damage or malf unct ion due to poor fuel
quality is not covered by the Audi New Ve
hicle Limited Warranty.
Diesel fuel
Applies to veh icles: w ith diesel engine
Always use ULSD (Ultra Low Sulfur Diesel)
No. 2. The ULSD No. 2 meets the ASTM D97S.
Diesel fuel with concentrations of biodiesel
highe r than S % such as Bll, B2O or BlOO are
strictly prohib ited .
Se rv ice stat ion fuel pumps are labeled with
the cor rect fuel informat ion for easy recogn i
tion by the user. If the diesel fuel pump is not
labeled ask the station operator what fuel is
being dispensed before filling up your vehicle.
ULSD No. 2 may not be available outside the
USA and Canada. Be sure to check before trav
eling to other countries .
ULSD No. 2 can become thicker in very cold
temperatu res, and this can impair the en
gine's start ing and running. Depending on the
season, gas stations provide ULSD No. 2 that
flows better in cold temperatures so that you
can continue operating your vehicle as usua l.
CD Note
-Yo ur vehicle's diesel engine was de
signed soley for use with ULSD No. 2.
Therefore, never use gasoline, heating oil, other fuels or flow improvers. These
conta in substances that will severely
damage the fuel system and the engine . .,.

fueled with gasoline or diesel fuel.
Refuelling procedure
~ Insert the fuel nozzle from the gasol ine
pump into the fue l filler neck as far as it will
go.
~ Se lect a medium refuelling rate so that the
no zzle switches off automatica lly when the
tank is full.
Putting the fuel cap back on
~ After filling your tank, twist the fuel fi ller
cap clockwise as far as it will go.
~ Close the fuel filler flap.
To avoid fuel spi lling or evaporating from the
fuel tank always close fuel fi ller cap properly
and comp lete ly. An improperly closed fuel fill
er cap may also cause the M IL lamp

to come on (only 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 burns and other injuries .
- 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 f iller neck or to over
flow. Fuel spray and ove rflow ing fuel can
cause a fire.
- Never use a cellular telephone wh ile re
fueling. The electromagnetic radiation
can cause sparks that can ignite fue l va
pors and cause a fire.
- Never get back into you r vehicle while re
fueling. If in exceptiona l circumstances
you must get back in your vehicle whi le
refueling, make certain that yo u close
the door and touch metal to discharge
static electricity before touching the fill
er nozzle again. Static electricity can
cause sparks that can ignite fuel vapors
released during 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 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). Stat ic electrici
ty can build up while filling and can ig
nite fuel vapors causing a fire .
- Always place a portable fuel conta iner
on the ground before filling.
- Always keep the filler no zzle complete
ly inside the portable container before
and dur ing filling .
- If filling a portable container made of
metal, the f iller nozzle must always be
in contact with the conta iner . This will
help prevent static electric ity from d is
charging and cause a fire .
- Never spill fue l inside the vehicle or
luggage compartment. Fuel vapors are
highly flammable .
- Always observe local and state/provin
cia l laws regarding the use, storage
and transportation of fuel containers.
- Make certain the fuel container meets
in dustry standa rds (ANSI/ AS TM
F852-86).
(D Note
If any fuel has spilled onto the car, it
shou ld be removed immediately to prevent
damage to the paint.
@ For the sake of the environment
As soon as the correctly operated nozzle
switches off automat ica lly for the first
time, the tank is full. Do not try to add
more fuel because fuel may spill out. In •

addition, the expans ion space in the fuel
tank will be filled -causing the fuel 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 fue l to spill out of the tank. This
would then shut off the fuel nozzle be
fore the tank is full.
- Do not refuel your vehicle w ith the igni
tion turned on. The fuel gauge may oth
erwise not ind icate the correct fuel level
after refuell ing.
- Diesel veh icles* are equipped with a die
sel misfueling protector. It allows the
vehicle to be fueled only w ith 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 turning
the nozz le before inserting it in the fue l
filler neck, use a different fuel pump or
see your authorized Audi dealer or au
thorized repair facility for assistance.

Selective catalytic
reduction
General information
Applies to vehicles: with diesel engine
On vehicles with selective catalytic reduction,
an urea solution (AdBlue) is injected into the
exhaust system before a nitrogen oxide cata
lytic converter to reduce nitrogen emissions.
The Ad Blue is stored in a separate tank in the
vehicle. The Ad Blue usage accounts for ap proximately 0.5% to 1.2% of the diesel fuel
that is used .
You must refill the Ad Blue or have it ref illed
by your authorized Audi dealer or qualified
workshop as soon as the Ad Blue refill mes
sage appears in the instrument cluster
¢page 254.
&_ WARNING ~
Failure to heed AdBlue refill information in
the instrument cluster can prevent the ve
hicle from being started and dr iven.
If the
vehicle cannot be driven and an emergency
arises, personal injury can occur.
