::r ' -If you are unable to determine whether or
not a particular fue l 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 identified.
- Fuel system damage and performance prob ­
l ems resulting from the use of fue ls differ­
ent from those specif ied are not the respon­
s ibility of Audi and are not covered under
the New Veh icle or the Emiss ion Control
System Warrant ies .
- If you experience a loss of fue l economy or
driveability and performance problems due
to the use of one of these fuel blends, we
r ecommend that you switch to unblended
fuel.
Gasoline additives
A ma jor concern among many auto manufactur ­
ers is carbon deposit build-up caused by the type
of gasoline yo u use.
A lthough gasoline grades d iffer from one manu­
facturer to another, they have certain things in
common . A ll gasoline grades contain substances
that can cause deposits to collect on vita l engine
parts, such as fue l injectors and intake valves. A l­
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 informat ion on TOP TIER Deter­
gent Gasoline, please go to the official website
(www .toptiergas .com) .
After an extended period of using inadequate
fuels, carbon deposit build-ups can rob your en­
g ine of peak performance.
@ Note
Damage or malfunction due to poor fuel q ual­
ity is not covered by the Aud i New Vehicle
Limited Warranty.
Ch eck ing and F illing
Diesel fuel
App lies to : veh icles w it h diese l eng ine
Always use U LSD (Ult ra Low Sulfur Diesel) No. 2.
T he ULSD No. 2 meets the AS TM D975.
D iesel fuel w ith concentrations of b iod iesel h igh­
er than 5
% such as B 11, B20 or B100 are strict ly
proh ib ited.
Service station fuel pumps are labeled with the
correct fuel information for easy recogn it ion by
the user . If the d iesel fue l pump is not labeled
ask the station operator what fuel is being dis ­
pensed before fill ing up your vehicle.
U LSD No . 2 may not be ava ilable outside the USA
and Canada . Be su re to check befo re traveling to
othe r countr ies.
ULSD No . 2 can become thicker in very cold tem­
peratures, and th is can impa ir the engine's start­
i ng and runn ing . Depend ing on the season , gas
stations provide ULSD No. 2 that flows bette r in
co ld tempe ra tures so that you can co nti nu e ope r­
at ing you r vehicle as usual.
{Qj) Note
- Yo ur vehicle's d iese l eng ine was des igned

never use gasoline, heating oil, other f uels
or flow improvers. These contain s ubstances
that will severely damage the fuel system
and the engine. Such damage will not be

Checking and Filling
Refueling
Fueling procedure
Fig. 254 Right re ar side of the vehicle : opening the fue l
filler door
Fig. 255 Fu el fi lle r door w it h atta ched fuel cap
The fuel f ille r door is unlocked or locked by the
central locking system .
• Press on the left side of the fuel filler door to
open
c:!;> fig. 254.
• Unscrew the tank cap counterclockw ise.
• Place the cap from above on the open fue l filler
door c:!;>fig. 255.
• Insert the fu el pump no zz le all the way into th e
fuel filler neck.
• Begin fueling . Once the fuel pump noz zle turns
off the first time, the fuel tank is full. Do not continue fueling , or else the expans ion space in
the tank will be filled with fuel.
• After the fuel pump has switched off , wait five
seconds before remov ing it to allow the rest of
the fuel to f inish dripp ing into the fuel tank.
• Turn the fue l cap clockwise until you hear it
lock.
• Close the fuel filler door and then pr ess on th e
left side until it latches.
The correct fu el type for your vehicle can be
found on a lab el located on the inside of the fue l
312
filler door. For additional information on fuel,
se e
c:!;> page 310.
For the tank capacity in your veh icle, refer to the
Technica l Data
c:!;> page 3 75 .
To reduce the risk of fuel leaking out or vapors
escaping, make sure that the fuel tank is closed
correctly. Otherw ise the
¢'4 ind icator light wi ll
turn on.
If the cent ral locking system malfunctions , the
fuel filler doo r may emergency re lease
c:!;> page 314.
& WARNING
An improper fueling procedure and improper
handling of fuel can lead to explosions, fires,
severe burns and other in juries.
- Do not smoke and keep away from open
flames.
- The ignition must be sw itched off when re­
fueling.
- Cell phones, radio devices and other rad io
equipment should a lways be switched off
when refueling. E lectromagnetic rays could
cause sparks and start a fire.
- If you do not insert the fuel pump nozzle all
the way into the filler tube, then fuel can
leak out. Spilled fuel can ignite and start a
fire .
- Never get into the vehicle when refueling . If
there is an exceptional situation where the
vehicle must be entered, close the door and
touch a metal surface before touching the
fuel pump nozzle again . This will reduce the
r isk of electrostatic discharge that can cause
f lying sparks. Sparks can start a fire when
refueling.
& WARNING
We recommend that you do not transpo rt any
f u el containers in the vehicle . Fuel could leak
out of the container and ignite, especially dur­
ing an accident. This can cause explosions,
fires and injuries.
- If you must transport fuel in a fuel contain­ er, p lease note the following :

-Always p lace a fuel container on the
ground before f illing. Never f ill the fuel
container with fuel while it is in or on the
ve hicle . Electrostatic charge can occur
while refuel ing and the fuel vapors could
ign ite .
- For fuel containers made of metal, the fuel pump nozzle must always ma intain
contact w ith the conta ine r to reduce the
r isk of static c harge.
- I nsert the fuel pump nozzle as fa r as pos­
sib le into the filler ope ning whi le ref uel­
ing.
- Follow legal requirements w hen using ,
sto ring a nd transpo rting fue l co nta ine rs .
- Make sure that the fuel container meets
the industry standa rds , fo r example ANSI
or AS TM F852-86 .
0 Note
- Remove fuel that has overflowed onto any
vehicle compo nents immed iate ly to reduce
t h e ris k of da mage to t he ve hicle.
-Never dr ive until the fuel tank is comp letely
empty . The irregu lar supply of fuel t hat re­
s ul ts from that ca n cause engine misfires.
Un comb usted f uel w ill en ter the ex ha ust
system an d increase the risk of damage to
t h e catalytic converter .
- Applies to: vehicles with a diesel engine: if
the fue l tank runs complete ly empty, the ig ­
nition m ust remain switched on for at least
30 seconds after refueling before starting
the engine . It may take longer than usual
fo r the engine to start, even up to a m inute.
This is because the air m ust first bleed o ut
of the fuel system when starting the engine .
@ For the sake of the environment
Do not overfill the fuel tan k, otherw ise fue l
can leak out when the vehicle is warm ing up .

Ch eck ing and F illing
(D Tips
The fuel filler door on your ve hicle does not
