Fuel and Refueling
Fuel and Refueling
Gasoline
Fuel supply
Applies to vehicles: with gaso li ne engine
Using the right fuel helps keep the environment
clean and prevents engine damage.
Fuel recommendation
The fuel recommended for your vehicle is unlead­
ed premium
grade gasoline . Audi recommends
using TOP TIER Detergent Gasoline with a mini­
mum octane rating of 91 AKI (95 RON). For more
information on TOP TIER Detergent Gasoline,
p lea se go to the offic ial website
(www.toptiergas .com).
The recommended gasoline octane rating for
your engine can also be found on a label located
on the ins ide of the fuel filler flap . This rating
may be specified as AKI or RON.
Your vehicle may also be operated using unlead­
ed regular gasoline with a minimum octane rat­
ing of 87 AKl/91 RON . However, using 87 AKI/91
RON octane fuel wil l slightly reduce engine per­
formance.
Use unleaded gasoline only. Unleaded gasoline
is availab le throughout the USA, Canada, and in
most European countries . We recommend that
you do not take your vehicle to areas or countries
where un leaded gaso line may not be available.
For more information on refueling your vehicle,
see
¢page 210.
Octane rating
Octane rating indicates a gasoline's ability to re­
sist engine damaging "knock" caused by prema­
ture ignit ion and detonation . Therefore, buying
the correct grade of gasoline is very important to
he lp prevent possible engine damage and a loss
of eng ine performance.
Gasoline most commonly used in the United
States and Canada has the following octane rat­
i n gs that can usually be found on the filler pump:
- Premium Grade: 91 - 96 AKI
208
- 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 low­
er than 87 AKI or 91 RON otherwise expen­
sive engine damage wi ll occur .
- Do
not use leaded gasoline. The use of lead­
ed gasoline will severely damage your vehi­
cle's catalytic converter and its ability to
control exhaust emissions .
Blended gasoline
Applies to vehicles: with gasoline engine
Use of gasoline containing alcohol or MTBE
(methyl tertiary butyl ether)
You may use unleaded gasoline blended with al­
cohol or MTBE (commonly referred to as oxygen ­
ates) 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 h igher.
- Blend must contain no more than 3% metha-
nol.
- Blend must contain more than 2% co-solvents.
Blend of gasoline and ethanol (grain alcohol or
ethyl alcohol)
- Anti-knock index must be 87 AKI or h igher .
- Blend must not contain more than 15% etha-
nol.
Blend of gasoline and MTBE
-Anti-knock index must be 87 AK I or higher .
- Blend must contain not mo re than 1S% MTBE.
Seasonally adjusted gasoline
Many gasoline grades are blended to perform es­
pecially well for winter or summer dr iv ing . Dur-
i ng seasonal change-over, we suggest that you .,..

fill up at busy gas st ations where the season al
adjustment is more likely to be made in time .
(D Note
-Me thanol f uels which do not mee t these re­
quirements may ca use corros ion and dam­
age to plastic and rubber components in the
fuel system .
- Do not use fuels that fai l to meet the speci­
fied criter ia in this chapter.
- If you are unable to determine whether or not a particular fuel blend meets the speci­
ficat ions, ask your service station or its fuel
supplier.
- Do not use fuel for which the contents can­
not be identif ied.
- Fuel system damage and performance prob­
lems resulting from the use of fue ls differ­
ent from those specified are not the respon­
s ibility of Audi and are not covered under
the New Veh icle or the Emiss ion Control
System Wa rrant ies.
- If you experience a loss of fue l economy or
driveability and performance prob lems due
to the use of one of these fuel b lends, we
recommend that you switch to unblended
fuel.
Gasoline additives
A ma jo r concern among many au to manufactur ­
e rs is carbon deposit build-up caused by the type
of gasoline you use.
A lthough gasoline gr ades d iffer from one manu ­
facturer to ano ther, they have cer tain things in
common . All gasoline grades contain substances
that can cause deposits to collect on v ita l eng ine
parts, such as f uel injectors and intake valves. Al­
though most gasoline brands include additives to
keep engine and fuel systems clean, they are not
equally effective.
Aud i recommends using TOP TIER Detergent Gas­
oline. For more informat ion on TOP TIER Deter­
gent Gasoline, please go to the official website (www .toptiergas .com) .
Fuel and R efueling
After an extended period o f using inadeq uate
fuels, carbon deposit bui ld-ups can rob your en­
gine o f peak performance.
(D Note
Damage or ma lf u nction due to poor fuel qual ­
ity is not covered by the A udi New Vehicle
Limited Warranty .
Diesel fuel
Applies to vehicles: with diesel engine
Always use ULSD (Ultra Low Sulfur Diesel) No. 2 .
The ULSD No . 2 meets the ASTM 0975.
Diesel f uel w it h concen tratio ns of b iod iesel h igh­
er than 5 % such as Bl 1, B20 or BlOO are strict ly
prohibited .
Se rvice station fuel p umps are labe led with the
correct f uel i nfo rmat ion for e asy recog nition by
the user.
If the d iesel f ue l pump is no t labeled
ask the station operator what fuel is being dis­
pensed before fil ling up your vehicle .
UL SD No . 2 m ay not be available ou tside the USA
and Canada . Be su re to check befo re t raveling to
other countries .
UL SD No . 2 c an become thic ke r i n ve ry cold tem­
peratures, and this can imp air the engine's s tart ­
ing and running. Depend ing on the sea son, gas
stations provide ULSD No . 2 that flows better in
cold temperatures so that you can continue oper ­
at ing your vehicle as usual.
@ Note
- Your vehicle's diese l engine was designed
soley for use w ith ULSD No . 2 . Therefo re,
neve r use gasoline, heating oil, other fuels
or flow improvers. These contain substances
that will severely damage the fuel system
and the engine . Such damage will not be
cove red by your New Vehicle Limited War­
r a nty.
- If you put a ny amo unt of incorrect fuel in
the fuel tank, do not sta rt the eng ine under
any circumstances. Imme diately contact the
ne arest a uthor ized A udi dealer or author­
ized Aud i Serv ice Facility fo r ass istance .

Fuel and Refueling
These fuels contain substances that can se ­
verely damage the fue l system and the en­
gine if the engine is started .
Refueling
Fuel filler neck
The fuel fill er neck is located on the right rear
side panel beh ind the fuel fil ler flap.
If the power locking system should fail , you can
still open the flap manually - for detailed instruc­
tions see ¢
page 212.
You can find the fuel tank capacity of your vehicle
i n
¢ page 271 .
The label on the inside of the fuel filler flap tells
you the correc t fuel for you r vehicle . For more in­
formation about fuel specifications , see
¢ page 208 .
Your vehicle fuel t ank has an onboard refuelling
vapor recovery system . This fea tu re helps to pre­
vent fuel vapors from escaping from the tank and
polluting the environment while you refuel your
vehicle. In order to fill the tank properly while
protecting the environment, please fo llow this
refueling procedure carefully.
8_ WARNING
Under normal operating conditions, never car­
ry additiona l fuel containers in your car. Gas
canisters and other containers used to trans­
port fuel can be dangerous . Such containers,
full or empty , may leak and could cause a fire
in a collision . If you must transport fuel to
use for your lawn mower, snow blower, etc.,
be
very careful and always observe local and
state laws regard ing the use, transportation
and storage of such fuel containers. Make cer­
tain the container meets industry standards
(ANSI/ASTM F852 -86).
(D Note
Never drive your vehicle until the fuel tank is
completely empty. T he irregular supply of
fue l can cause m isfiring. Gasoline could enter
the exhaust system and damage the catalytic
converter.

Refuelling
Fig. 178 Righ t re ar v ehicl e side : O penin g the fuel fill er flap
Fig. 179 Fuel fille r flap w it h att ach ed fuel c ap
When act iv a ting the central locking, the fuel fill­
er flap is automatically unlocked or locked. Re ­
fuel the veh icle with the ignition switched
off.
Taking the fuel cap off
.. Press the left s ide of the fuel filler flap to open
i t ¢
fig. 178 -arrow-.
.. Unscrew fuel filler cap counter-clockwise and
hang it on the fuel filler flap~
fig. 179.
.. Check the label on the inside of the fuel filler
flap to determine if the vehicle must be fueled
w ith gasoline or diesel fuel.
Refuelling procedure
.. Insert the fuel nozzle from the gasoline pump
into the fuel filler neck as far as it will go .
.. Select a med ium refuelling rate so that the
nozz le switches off automatica lly when the
tank is full.
Putting the fuel cap back on
.. After filling your tank, twist the fuel filler cap
clockw ise as far as it will go .
.. 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
c> page 28 to come
on.
A WARNING
Improper refueling or handling of fuel can
cause fire, explosion and severe burns.
- Fuel is highly flammable and can cause se­
vere burns and other injuries.
- Failure to shut the engine off while refuel­
ing and/or to insert the pump nozzle fully
into the fuel filler neck could cause fuel to
spray out of filler neck or to overflow. Fuel
spray and overflowing fuel can cause a fire.
- Never use a cellular telephone while refuel­
ing. The electromagnetic radiation can
cause sparks that can ignite fuel vapors and
cause a fire.
-
-Never get back into your vehicle while refu­
eling.
If in exceptional circumstances you
must get back in your vehicle while refuel­
ing, make certain that you close the door
and touch metal to discharge static electric­
ity 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 any­ where 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 exam­
ple, 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.
Fuel and Refueling
- 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 lug­
gage compartment. Fuel vapors are highly
flammable .
- Always observe local and state/provincial
laws regarding the use, storage and trans­
portation of fuel containers.
- Make certain the fuel container meets in­ dustry standards (ANSI/ ASTM F852 -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 pollute the environment.
(D 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 before the tank is full.
- Do not refuel your vehicle with the ignition
switched on. The fuel gauge may otherwise
not indicate the correct fuel level after refu­
elling.
- Diesel vehicles* are equipped with a diesel
misfueling protector.
It allows the vehicle
to be fueled only with a diesel fuel pump nozzle. A worn or damaged nozzle or a noz­
zle that is too small may not be able to open
the diesel misfueling protector. If this is the .,..
211

case, try turning the nozzle before inserting
it in the fuel fi ller neck, use a different fue l
pump or see your authorized Audi dea ler or
authorized repair facility for ass istance.
- The fuel filler flap of your vehicle is not
locked when you lock the vehicle from the
inside.

Selective catalytic reduction
General information
Applies to vehicles: with selective catalytic reduction
In vehicles with selective catalytic reduction, a
urea solution (AdBlue) is injected into the ex­
haust system before a nitrogen oxide catalytic
converter to reduce nitrogen emissions.
The Ad Blue is carried in a separate tank in the ve ­
hicle. The AdBlue usage accounts for approxi­
mately 0.5% to 2.5% of the diesel fuel that is
used.
When a message about refilling the AdBlue ap­
pears in the instrument cluster display, you must
refill the Ad Blue yourself or have it refilled by an
authorized Audi dealer or authorized Audi Service
Facility
r:!.>page 213 .
{!) Tips
-The instrument cluster display ind icates the
distance remaining that can be driven
¢ page 213. If the AdBlue tank is com­
pletely empty, the engine will not start
again after the ign ition is switched off.
- Ad Blue is required by law to operate th is ve­
hicle.
