Fuel supply
A pp lies to veh icles: w ith gaso line engine
Using the right fuel helps keep the environment
clean and prevents engine damage.
Fuel r eco mmendation
The f uel recommended for your vehicle is unlead­
ed premium
grade gaso line. A udi recommends
using TOP TIER Detergent Gasoline with a min i­
mum octane rating of 91 AKI (95 RON). For more
info rmation on TOP TIER Detergent Gasoli ne,
p lease go to the official website
(www.toptiergas.com).
The recommended gasoline octane rating for
your engine can a lso be found on a label located
on the ins ide of the fue l filler flap. This ra ting
may be specified as AKI or RON.
Your vehicle may also be operated using unlead­
ed regula r gasol ine with a minimum octane rat­
ing of 87 AKl/91 RON. However, using 87 AKl/91
RON octane fue l will slight ly reduce eng ine per­
for mance.
Use unleaded ga soline only. Unleaded gasoline
is available th roughout the USA, Canada, and in
most European cou ntries. We recommend t hat
you do not ta ke yo ur vehicle to a reas or coun tries
where unlea ded gaso line may no t be ava ilab le.
For mo re info rmat ion on refueli ng your ve hicle,
see
¢page 212.
Octane rat ing
Octane rating ind icates a gaso line's ability to re­
sist engine damaging "knock" caused by prema­
ture ignition and detonation. The refore, buying
the co rrect g rade of gasoline is very importa nt to
he lp p revent possible eng ine damage a nd a loss
of eng ine pe rforma nce.
Gasoline most commonly used in the Un ited
States and Canada has the following octane rat­
i n gs that ca n usually be found on the filler pump:
- Prem ium G rade: 91 - 96 AKI
210
- Regular Grade: 8 7 -90 AKI
E xplanation of the abb revia tions:
AKI = Anti Knock Index= (R+M)/2 = (RON+MON)/
2
RON= Research Octane Number
M ON= M otor Octane Number.
{[) Note
-Do not use a ny fue l w ith o ctane rat ings low­
er th an 8 7 AKI or 91 R ON othe rwi se e xpe n­
sive engine damage w ill occur .
- Do
not use le ade d gas oline . The u se of le ad­
e d gasoline will severely damage your veh i­
cle's cataly tic conver ter and i ts ab ility to
cont rol exha ust em issions.
Blended gasoline
App lies to vehicles: wit h gaso line e ngi ne
U se of g asoline cont aining alcohol or MTBE
(methyl tert iary butyl ether)
You may use unleaded gasoline blended with a l­
cohol or MTBE (commonly referred to as oxygen­
ates) if th e b le nded mixture mee ts the following
c riteria :
Blend of gasoline methanol (wood alcohol or
methyl alcohol)
- Anti -knoc k index must be 8 7 AKI or higher.
- Blend must contain no more t han 3% metha-
nol.
- Blend must contain more than 2% co -solven ts.
Blend of gasoline and ethanol (grain alcohol or
ethyl alcohol)
- Anti-knoc k index mus t be 87 AKI or higher.
- Blend must not conta in more than 15% etha-
nol.
Blend of gasoline and MTBE
- Anti-knoc k index mus t be 87 A KI or high er.
- Blend mus t contain no t mo re tha n 1S % M TBE.
Seasonally adjusted gasoline
Many gasoline grades are blended to perfo rm es ­
pecially well for winter or s ummer dr iv ing . Dur-
i ng seasonal change-over, we suggest that you .,..

fill up at busy gas stations where the seasonal
adjustment is more likely to be made in time.
(D Note
- Methanol fuels which do not meet these re­
quirements may cause corrosion and dam­
age to plastic and rubber components in the
fuel system.
- Do not use fue ls that fail to meet the speci­
fied criteria in this chapter.
- If you are unable to determine whether or
not a particular fuel blend meets the speci­
fications, ask your service station or its fuel
supplier.
- Do not use fuel for which the contents can­
not be identified.
- Fuel system damage and performance prob­
l ems resulting from the use of fuels differ­
ent from those specified are not the respon­
s ibility 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 problems due
to the use of one of these fuel blends, we
recommend that you switch to unb lended
fuel.
Gasoline additives
A ma jor concern among many auto manufactur­
ers is carbon deposit build-up caused by the type
of gasoline you use.
Although gasol ine grades differ from one manu­
facture r to another, they have certa in things in
common. All gasoline grades contain substances
that can cause deposits to collect on vita l engine
parts, such as fuel injectors and intake valves. Al­
though most gasoline brands include additives to
keep engine and fuel systems clean, they are not
equally effective .
Audi recommends using TOP TIER Detergent Gas ­
oline. For more information on TOP TIER Deter-
M gent Gasoline, please go to the official website N
j (www .toptiergas.com).

Fuel and Refueling
After an extended period o f using inadequate
fuels, carbon deposit build-ups can rob your en­
gine of peak performance .
(D Note
Damage or malfunction due to poor fuel qual­
ity is not covered by the Audi New Vehicle
Limited Warranty.
Diesel fuel
Applies to vehicles: with diesel engine
Always use ULSD (Ultra Low Su lfur Diesel) No. 2.
The ULSD No. 2 meets the ASTM 0975.
Diesel fuel with concentrations of biodiese l high­
er than 5
% such as Bl 1, B20 or 8100 are strictly
prohibited.
Service station fue l pumps are labeled with the
correct fue l information for easy recognit ion by
the user .
If the d iese l fue l pump is not labe led
ask the station operator what fuel is being dis­
pensed before fi lling up your vehicle.
ULSD No. 2 may not be available outside the USA
and Canada . Be sure to check before traveling to
other countries.
ULSD No. 2 can become thicker in very cold tem­
peratures, and this can impair the engine'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 oper­
ating your vehicle as usual.
@ Note
- Your vehicle's diesel engine was designed
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 . Such damage will not be
covered by your New Vehicle Limited War­
ranty.
- If you put any amount of incorrect fuel in
the fuel tank, do not start the engine under
any circumstances. Immediately contact the
nearest authorized Audi dealer or author­
ized Audi Service Facility for assistance.

Fuel and Refueling
These fuels contain substances that can se ­
verely damage the fuel system and the en­
gine if the engine is started.
Refueling
Fuel filler neck
The fuel filler neck is located on the right rear
side pane l beh ind the fuel filler flap .
If the power locking system should fail, you can
still open the flap manually - for detailed instruc­
tions see
¢page 214.
You can find the fuel tank capacity of your vehicle
in
¢ page 272 .
The label on the inside of the fuel filler flap tells
you the correct fuel for your vehicle. For more in­
formation about fuel specifications, see
¢ page 210 .
Your vehicle fuel tank has an on board refuelling
vapor recovery system. This feature helps to pre­
vent fuel vapors from escaping from the tank and polluting the environment while you refue l your
vehicle. In order to fill the tank properly whi le
protec ting the environment, please follow this
refueling procedure carefully.
8_ WARNING
Under normal operating conditions, neve r ca r­
ry additional 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 mowe r, snow blower, etc.,
be very careful and always observe loca l and
state laws rega rding the use, transportation
and storage of such fuel containers. Make cer­
tain the con tainer meets industry standards
(ANSI/ASTM F852 -86).
(D Note
Never drive you r vehicle until the fuel tank is
completely empty. The irregu lar supply of
fue l can cause misfiring. Gasoline could enter
the exhaust system and damage the catalytic
converter.

Refuelling
Fig. 180 R ig ht rea r ve hicle side : Opening the fuel fill er flap
Fig. 181 Fuel fille r flap w ith attac hed fuel cap
When act ivating 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 side of the fuel f iller flap to open
it ¢
fig. 180-arrow-.
.. Unscrew fuel filler cap counter-clockwise and
hang it on the fuel filler flap
~ fig . 181 .
.. Check the label on the ins ide of the fuel filler
flap to determine if the vehicle must be fue led
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 medium refuelling rate so that the
nozzle switches off automatically 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 . ..,_

M N <( (.J

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 cau se the MIL lamp¢
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 noz zle 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 noz­
zle . 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 .,..
213

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

Selective catalytic reduction
General information
Applies to vehicles: with selective catalyt ic red uction
In vehicles with selective catalytic reduction, a
urea solution (AdB lue) 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 Ad Blue usage accounts for approxi­
mately O. 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

Using the proper engine o il is important for the
functiona lity and service life of the engine. Your
engine was factory-fi lled with a high-quality oil
which can usually be used throughout the entire
year.
@ Note
Your L imited New Vehicle Warranty does not
cover damage or malfunctions due to failure
to follow recommended maintenance and use
req uirements as set forth in the Audi Owner's
Manual and Warranty
& Maintenance booklet.
- Use only a high quality eng ine oil that ex-
pressly complies w ith the Audi o il quality
standard specified for your veh icle's engine.
Using any other oil can cause serious engine
damage .
- Do not mix any lubricants or other additives
into the engine oil. Doing so can cause en­
gine damage.
(D Tips
If you need to add oil and there is none availa­
ble that meets the Audi o il quality standard
your eng ine requires, you may add a total of
no more than 0.5 quart/liter of a high-quality
"synthet ic"oil that meets t he followi ng speci­
fications.
- Vehicles with gaso line engine: ACEA A3 or
API SM with a viscosity g rade of SAE OW-30,
SAE SW-30 or SAE SW-40.
- Vehicles with diesel engine: AC EA C3 or
API CF with a v iscosi ty grade of SA E OW -30
or SA E SW-30.

Checking and Fillin g
Engine oil consumption
The engine in your vehicle depends on on ade­
quate amount of oil to lubricate and cool oil of
its moving ports.
In order to provide effective lubricat ion and cool­
i ng of internal engine components, all internal
combust ion eng ines consume a certain amount
of oil. Oil consumpt io n varies from eng ine to en­
gine and may change sign ificantly over the life of
the engine. Typi cally, engines wi th a specified
break -in period (see
¢ page 196) consume more
o il during the b reak-in period than they consume
after oil consumption has stabilized .
Under normal cond itions, the rate of oil con­
sumption depends on the quality and viscos ity of
the oil, the RPM (revolutions per min ute) at
which the engine is operated, the ambient tem­
perature and road conditions. Further factors are
the amount of oil dilution from water condensa­
t ion or fuel residue and the ox idation level of the
o il. As any engine is subject to wear as mileage
builds up, the oil consumption may increase over
