Fuel filler neck
The fuel fille r neck is located on the right rear
s ide pan el behind the fu el filler flap .
I f the power locking system should fail, you can
still open the flap manua lly -for detai led instruc­
tions see
c::> page 300.
You can find the fuel tank capac ity of you r vehicle
in
c::> page 362 .
The label on the inside of the fuel filler flap tells
you the correct fue l for your vehicle . For more in­
formation about fue l specifications , see
c::> page 296 .
Your veh icle fuel tank has an onboard refuelling
vapor recovery system . This feature he lps to pre­
ve nt fuel vapors from escap ing from the tank and
pollut ing the e nvironment while yo u re fuel your
veh icle. In order to fi ll the tank properly while
protecting the environment, please fo llow this
r e fu eling procedure carefu lly.
& WARNING
Under normal operating conditions, never car­
ry additiona l fuel containers in yo ur car. Gas
canisters and other conta iners used to trans­
port fuel can be dangerous . S uch containers,
full or empty , may lea k and could cause a fire
in a collision. If yo u m ust t ransport fue l to
use for yo ur lawn mower, snow blower, etc.,
be very careful and a lways obse rve loca l and
state laws regard ing the use, t ransportation
and sto rage of such fue l conta iners. Make cer­
tain the container meets industry standards
(ANSI/ASTM F852 -86).
(D Note
Never drive yo ur vehicle unt il the fuel tan k is
comp letely empty . The irregular supply of

A WARNING -
Not paying attention when fueling or han ­
dling fue l incorrectly can lead to fires, exp lo ­
sions or serious injuries.
- Fuel ignites easily and can cause serious
burns and other injuries.
- If you do not switch the engine off when fu ­
eling and/or do not insert the fuel nozz le
completely into the tank opening, fue l can
leak out or run over . Leaked fuel can ignite
and start a fire .
- Do not use the telephone whi le fueling. The
electromagnetic rays can cause sparks,
wh ich can ignite fuel vapors and start a fire .
- Do not sit in your vehicle while fueling. If
you must make an except ion and enter your
vehicle again wh ile fueling , close the door
and touch meta l to discharge static electric­
ity befo re touching the fue l nozzle . Static
elect ricity can create spar ks, wh ich can ig ­
nite vapors when fue ling.
- Do not smoke or have an open flame in the
area when fueling your veh icle or filling a
fuel contai ner because th is increases the
risk of an explosion .
- For yo ur safety , carrying f uel containers in
yo ur vehicle is no t recommended. Whethe r
f ull or empty, the conta iner can leak and
cause a fire in the event of an accident .
- If you must make an exception and trans­
port a fuel container, note the following :
- Never fill the fuel container with fuel
while it is in or on the vehicle. Stat ic elec ­
tr icity is d ischa rged when filling wh ich can
cause the f uel vapors to ignite and in­
creases the r isk of an explos ion.
- Always p lace a fuel container on the
g ro u nd before fi llin g.
Ch eck ing and Filling
-Always hold the fuel nozzle completely in
the fuel container when filling .
- If the fuel container is made of metal, the
fuel nozzle must always be in contact with
the container when filling it with fuel. This
prevents stat ic electricity from discharg­
ing .
- Never spill fuel in the vehicle or the lug­
gage compartment . Evaporated fuel is ex­
plosive and increases the risk of serious in­
jury or death .
- Follow lega l requirements when using,
stor ing and transporti ng fuel containers .
- Make sure the fuel container conforms to
industry standards (ANSI/AS TM F8S2 -86).
@ Note
- Remove spilled fuel from vehicle pa int im­
mediately, because it can damage paint.
- Never drive until the fuel tank is complete ly
empty. The irregular supply of fue l that re­
sults from that can cause eng ine misfires.
Uncombusted fuel will enter the exhaust
system and increase the risk of damage to
the catalytic converter .
- If the fuel tank runs complete ly empty in a
vehicle with a diesel engine , the ignition
must remain switched on fo r at least 30
seconds afte r ref ueli ng before starting the
eng ine. It may take longer than usual fo r
t he engine to s tart, even up to a minu te .
T his is because the air must first b leed out
of the fue l system when starting the eng in e.
@ For the sake of the environment
Do not overfill the fuel tank, otherwise fuel
can leak out when the vehicle is warming up.
(D Tips
D iesel ve hicles are eq uipped w ith a diesel mis­
fueling guard .
It allows the vehi cle to be fu­
eled on ly with a diesel fuel pump nozzle. A
worn or damaged nozzle or a nozzle that is
too small may not be able to open the diese l
misfueling guard. If this is the case, try turn­
i ng the nozzle before inserting it in the fue l
filler tube, use a different fuel p ump or see an

Selective catalytic
reduction (AdBlue)
General information
Applies to: vehicles with selective catalytic reduct ion
In vehicles with selective catalytic reduction, a
urea solution (AdBlue) is injected into the ex­
haust system before a nitrogen oxide cata lytic
converter to reduce nitrogen emissions.
The Ad Blue is carried in a separate tank in the ve­ hicle. The Ad B lue usage accounts for approxi­
mately 1.0% to 2.5% of the diesel fuel that is
used.
When a message about refi lling the AdBlue ap­
pears in the instrument cluster display, you must
ref ill the Ad B lue yourself or have it refilled by an
authorized Audi dealer or authori zed Audi Service
Facility

Emissions control
systems
Catalytic converter
Applies to vehicles a with gasoli ne engine : the
vehicle may only be driven with unleaded gaso­ li ne, otherwise the cata lytic converter will be de­
stroyed .
Never dr ive until the tank is complete ly empty.
The irregu lar supply of fuel that resu lts from that
can cause eng ine misfires. Uncombusted fue l will
enter the exhaust system, which can cause over­
hea ting and damage to the cata lytic converter .
Diesel particulate filter
Applies to vehicle s with a diesel engine : the die­
sel part icu late filter filters nearly all of the soot
particles out of the exhaust. The f ilter cleans it­
self automatically under normal dr iv ing cond i­
t ions .
If the filter cannot clean itself (fo r exam­
ple, bec ause you are only d rivi ng short distan­
c es), the filte r becomes clogged wi th soo t and

the eng ine.
-
- Never touch the exhaust tail pipes once they
have become hot. This cou ld res ult in burns.
- Do not park your veh icle over flammable
materials such as grass or leaves because
the high temperature of the emissions con­ trol system (catalytic converter or d iesel
pa rtic ulate filter) could start a fire.
- Do not app ly underbody protectant in the

Audi recomm ends Longlife high perf orma nce
engine oil from Aud i Genuine Parts
Using the proper engine oil is important for the
functionality and service life of the eng ine. Your
engine was factory-filled with a high-quality oil
which can usually be used throughout the entire
year.
(D Note
Your Limited New Vehicle Warranty does not
cover damage or malfunctions due to failure
to follow recommended maintenance and use
requirements as set forth in the Aud i Owner's
Manual and Warranty
& Maintenance booklet .
- Use only a high quality eng ine oil that ex-
pressly complies with the Aud i oil quality
standard specified for your vehicle's engine .
U si ng a ny other oil can cause serious engine
damage.
- Do not mix any lubr icants or othe r additives
i nto the engine oil. Doing so can cause en­
gine damage.
If you need to add oil and there is none availa­
ble that meets the Audi o il quality standard
your eng ine requ ires, you may add a tota l of
no more than 0 .5 qua rt/liter of a h igh-quality
"synthetic"oil that meets the following speci­
fications.
- Vehicles with gasoline engine: AC EA A3 or
API SM with a viscosity grade of SAE OW-30,
SAE SW-30 or SAE 5W-40.
- Vehicles with diesel engine: ACEA C3 or API CF with a viscosity grade of SAE OW-30
or SAE 5W-30.

Engine oil consumption
The engine in your vehicle depends on on ade­
quate amount of oil to lubricate and cool all of
its moving ports.
In order to provide effective lubrication and cool ­
ing of internal engine components, all internal
combust ion eng ines consume a certa in amount
of oil. Oil consumption varies from eng ine to en­
gine and may change s ignificantly over the life of
the engine. Typ ically, engines w ith a specified
break-in period (see
c::> page 73) consume more
o il during the break-in per iod than they consume
after oil consumpt ion has stabil ized.
Under normal cond itions, the rate of oil con­
sumption depends on the quality and viscos ity of
the oil, the RPM (revolutions per minute) at
which the engine is operated, the amb ient tem­
peratu re and road co ndit ions. Furt her fac to rs a re
the amo unt of oil di lution from wate r condensa­
tion or fuel residue and the oxidation level of the oi l. As any engine is subject to wear as mileage
builds up, the oil consumption may increase over
time unt il replacement of worn components may
become necessary.
With a ll these variab les coming into play, no
standard rate of oil consumption can be estab­
lished or spec ified . There is no alternative to reg­
ular and frequent checking of the oi l level, see
Not e.
If the yellow engine oil level warning symbo l El
in the instrument cluster lights up, you should
check the oil level as soon as possible

Driving with an insufficient oil level is likely to
cause severe damage to the engine .
@ Tips
-The oil pre ssure warn ing display. is not
an ind icato r of the oil l evel. Do not rel y on
it. In stead , che ck th e oil le vel in your e n­
gi ne a t regul ar int ervals, prefe rably e ach
t ime you re fuel , and al ways befo re go ing
on a long trip .
-If you have the impression your engine con­
sumes excessive amounts of oil, we recom­
mend that you consult an authorized Aud i
dealer to have the cause of your concern
properly d iagnosed . Keep in mind that the
accurate measurement of oil consumpt ion
r equi res great ca re and may take some
time. An authorized Audi dealer has instruc­
tions about how to measure oil consump­
tion accurately.
Checking the engine oil level
The engine oil level can be checked in the Info­
tainment system
.. Park you r vehicle on a level surface.
.. Shut the engine off when it is warm.
.. Switch only the ignition back on.
.. Wait approximately two minut es .
.. Se lect in the Infotainment system: the
I MENU I
button > Ve hicle > left cont rol button > S er vice
& c h ecks > Oil lev el.
.. Check the oil level in the Infotainment system
display . Add engine oil if the bar in the oil level
indicato r is near "min "¢
page 308 .
The engine oil consumpt ion may be up to
0 .5 quart pe r 600 miles (0.5 l iter/1,000 km), de­
pending on driving style and operating condi­
tions. Consumption may be highe r d uring the
fi rst 3 ,000 mi les (5,000 km). Because of this, the
engine o il level must be checked regu larly. I t
wou ld be best to check each time you refuel your
vehicle and before long drives .

(D Tips
The oil level indicator in the disp lay is only an
i nformat ional disp lay .
If the oil leve l is too
l ow, a min imum oil warning appears in the in­
strument cluster. Add oil and close the hood.
The current oil level is displayed in the instru ­
ment cluster the next t ime the ignition is
switched on.
