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 :

Checking and Filling
If the indicator light does not turn off, drive im­
mediately to an authorized Audi dea ler or author­
ized Audi Service Fac ility to have the malfunction

high, both whe n driving and after stopping
the engine .
- Never touch the exhaust ta il pipes once they
have become hot. This could result in burns .
- Do not park you r vehicle over flammable
materials such as g rass or leaves because
the h igh temperat ure of the emiss ions con­
t rol sys tem cou ld start a f ire.
- Do not apply underbody p rotectant in the
exha ust system a rea, because this increases
the risk of fire.
- Applies to: vehicles wi th diesel particulate
filte r: always adjus t your speed to the

Applies to: ve hicles with diesel particulate filter
- Due to the high temperatures that occur
d uring diesel pa rticu late filter regenerat ion,
the radiator fan may continue runn ing after
the engine stops, even if the engine did not reach its operat ing temperatu re.
- Noises, odors and increased speeds may oc­
cur d uring the regeneration.
- Always use the co rrect engine oil and fuel to
ens ure that the serv ice life of the d iesel par­
ticulate filter is not reduced.

Checking and Filling
- Engine exhaust, some of its constituents,
and certain vehicle components contain or
emit chemicals known to the State of Cali­
forn ia to cause cancer and birth defects and
reproduct ive harm . In addition, certain flu­
ids contained in veh icles and certain prod­
ucts of compo nent wear contain or emit
chemicals known to the State of California
to cause cancer and birth defects or other reproductive harm .
- Battery posts, termina ls and related acces­
sories contain lead and lead compounds, chemicals known to the State of California
to cause cancer and reproductive harms.
Wash hands after handling .
(D Note
When filling flu ids, be sure not to mix the flu ­
ids up . Otherwise severe ma lfunctions and en­
gine damage w ill occur .
@ For the sake of the environment
You shou ld regularly check the ground under
your vehicle in order to detect leaks quickly. If
there are visible spots from oil or other fluids,
bring your vehicle to an authorized Audi deal­
er or author ized Audi Service Facility to be
checked .

A WARNING
-Never open the hood when there is steam or
coo lant escaping from the engine compart­
ment, because there is a risk that you could
be burned. Wait until no steam or coolant is
escaping.
- For safety reasons, the hood must always be
closed securely while driving . Because of
this, always check the hood after closing it
to make sure it is latched correctly . The
hood is latched if the front corners canno t
be lifted .
- If you notice that the hood is not latched
while you are driving, stop immed iate ly and
close it, because driving when the hood is
not latched increases the r isk of an accident . ..,.

Check ing and F illing
Detergent additives in the oil will make fresh oi l
look dark after the engine has been running for a
short t ime. Th is is norma l and is not a reason to
change the oil more often than recommended.
Because of the prob lem of p roper disposa l, along
with the special tools and necessary expertise re­
qu ired, we strongly recommend that you have
your oil changed by an authorized
Audi dealer or
a qualified service station .
If you choo se to change your oil your self , please
note the following important information:
A WARNING
To reduce the risk of personal injury if you
must change the engine oil in your veh icle
yourself:
- Wear eye protection.
- To reduce the risk of burns from hot engine
o il, let the eng ine cool down to the touch.
-
- When removing the oi l drain plug with your
fingers, stay as far away as poss ible. A lways
keep your forearm paralle l to the ground to
help prevent hot oi l from running down your
arm.
- Drain the oil into a container des igned for
this purpose, one large enough to hold at least the total amount of oil in your eng ine .
- Engine oil is poisonous. Keep it well out of
the reach of chi ldren .
- Cont inuous contact w ith used engine oil is
harmful to yo ur sk in. A lways protect your
sk in by washing o il off thoroug hly w ith soap
and water.
@ Note
Never mix o il add it ives wit h your engine o il.
These additives ca n damage your eng ine and
adversely affect your Aud i Lim ited New Veh i­
cle Warranty.
@ For the sake of the environment
- Before changing your oil, f irst make sure
you know w here yo u can properly dispose of
the used oil.
- Always dispose of used engine oil properly. Do not dump it on garden soi l, wooded
324
areas, into open streams or down sewage
drains.
- Recycle used engine o il by ta king it to a used
engine oi l collection facility in yo ur a rea, or
contact a service station.

General information
~check your tires regularly for
damage (punctures, cuts, cracks
and bulges). Remove foreign ob ­
jects from the tire tread.
~ If driving over curbs or similar
obstacles, drive slowly and ap­ proach the curb at an angle.
~Have faulty tires or rims re­
placed immediately.
~ Protect your tires from oil,
grease and fuel.
~ Mark tires before removing
them so that the same running
direction can be maintained if
they are reinstalled.
~Lay tires flat when storing and
store them in a cool, dry location
with as little exposure to light as
possible.
_&. WARNING -
-Never drive faster than the maximum permitted speed
for your tires. This could cause
the tires to heat up too much.
This increases the risk of an
accident because it can cause
the tire to burst .
-Always adapt your driving to the road and traffic condi-
330
tions . Drive carefully and re­
duce your speed on icy or slip­
pery roads . Even winter tires
can lose traction on black ice.
(@ Note
-Please note that summer and
winter tires are designed for
the conditions that are typical
i n those seasons . Aud i recom­
mends using winter tires dur­
ing the winter months . Low
temperatures significantly de­
crease the elasticity of summ­
er tires, which affects traction
and braking ability. If summer
tires are used in very cold
temperatures, cracks can form
on the tread bars, resulting in
permanent tire damage that
can cause loud driving noise
and unbalanced tires.
-Burnished, polished or chromed rims must not be used in winter driving condi­
t ions. The surface of the r ims
does not have sufficient corro­
sion protection for this and
could be permanently dam ­
aged by road salt or similar
substances.

Wheels
Please note that the TPMS is not a substitute for
proper tire maintenance, and it is the driver's re­
sponsibility to maintain correct tire pressure,
even if under-inflation has not reached the level
to trigger illumination of the TPMS low tire pres­
sure telltale.
Your vehicle has also been equipped with a TPMS
malfunction indicator to indicate when the sys­
tem is not operating properly. The TPMS mal­
function indicator is combined with the low tire pressure telltale. When the system detects a
malfunction, the telltale will flash for approxi­
mately one minute and then remain continuously
illuminated. This sequence will continue upon
subsequent vehicle start-ups as long as the mal­
function exists.
When the malfunction indicator is illuminated,
the system may not be able to detect or signal
low tire pressure as intended. TPMS malfunctions
may occur for a variety of reasons, including the
installation of replacement or alternate tires or
wheels on the vehicle that prevent the TPMS
from functioning properly . Always check the
TPMS malfunction telltale after replacing one or
more tires or wheels on your vehicle to ensure
that the replacement or alternate tires and
wheels allow the TPMS to continue to function
properly.
If the tire pressure monitoring indicator
appears
Applies to: vehicles with Tire Pressure Monitoring System in­
dic ato r
The tire pressure indicator in the instrument
cluster informs you if the tire pressure is too low
or if there is a system malfunction.
Using the ABS sensors, the tire pressure monitor ­
ing system compares the tire tread circumfer­
ence and vibration characteristics of the individu­
al tires . If the pressure changes in one or more
tires, this is indicated in the instrument cluster
display with an indicator light
RI] and a message.
If only one tire is affected , the location of that
tire will be indicated.
The tire pressures must be stored in the Infotain­
ment system again each time the pressures
348
change (switching between partial and full load
pressure) or after changing or replacing a tire on
your vehicle ~
page 349. The tire pressure moni­
toring system only monitors the tire pressure you have stored. Refer to the tire pressure label for
the recommended tire pressure for your vehicle
~ page 340, fig . 272.
Tire tread circumference and vibration character­
istics can change and cause a tire pressure warn­
ing if:
- the tire pressure in one or more tires is too low
- the tires have structural damage
- the tire was replaced or the tire pressure was
changed and it was not stored
