-Blend must contain not more than 1S%
MTBE.
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 . .,.

Such damage will not be covered by your
New Vehicle Limited Warranty.
- If you p ut any amount of incorrect fuel in
the fue l tank, do not start the engi ne un­
der any circumstances. Immediately con­
tact the nearest authorized Audi dealer
or authorized Audi Service Facility for as­
s istance. These fuels contain substances
that can severely damage the fuel sys­
tem and the engine if the engine is start­

Fuel tank
Fuel filler neck
The fuel filler neck is located on the right rear
side panel behind the fuel filler flap.
If the power locking system should fail, you
can st ill open the flap manually -for detailed
instructions see
c;,page 252.
You can find the fue l tank capacity of your ve­
hicle in
c;,page 325.
The label on the inside of the fue l filler flap
tells you the cor rect fuel for your vehicle. Fo r
more information about fuel specifications,
see
c::> page 248.
Your veh icle fuel tank has an on-board refuel­
ling vapor recovery system. This feature helps
to prevent fu el vapors from escaping from the
tank and polluting the environment while you refuel your vehicle. In order to fill the tank
properly whi le protecting the environment,
please follow t his refueling procedure careful­
ly .
A WARNING
Under normal operating conditions, neve r
carry additiona l fuel containers in you r car.
Gas canisters and other containers used to
transport fuel can be dangerous. Such con­
tainers, full or empty, may leak and could
cause a fire in a collision. If you must
transport fue l to use for yo ur lawn mower,
snow blower, etc., be very careful and al­
ways observe local and state laws regard­
ing the use, transportation and storage of such
fuel containers . Make certain the con­
tainer meets industry standards (ANSI/
ASTM F852 -86).
(D Note
Never drive your vehicle until the fue l 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 .

~ Check the label on the inside of the fuel fi ll­
er flap to determine if the vehicle must be
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
r=) page 2 7
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 •
•

252 Fuel supply and filling your fuel tank
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.
Unlocking the fuel filler flap by hand
You con open the fuel filler flop by hand if the
power locking system should foil.

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.
- Always have the AdBlue tank refilled we ll
before the tank runs dry. .,.
