-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
lems resulting from the use of fuels differ­
ent from those specified are not the respon­
sibility 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 unblended
fuel.
Gasoline additives
A major concern among many auto manufactur­
ers is carbon deposit build-up caused by the type
of gasoline you use.
Although gasoline grades differ from one manu ­
facturer to another, they have certain things in
common. All gasoline grades contain substances
that can cause deposits to collect on vital 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
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
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.

Plug-in hybrid drive*: refer to the information un­
der ¢pag e 103, Refueling .
The fuel filler door is unlocked or locked by the
central locking system.
.,. Applies to: vehicles with plug-in hybrid drive:
note the information

.,. Applies to : vehicles without plug-in hybrid
drive: to open, press on the left side of the fuel
filler
door¢ fig. 260 .
.. Unscrew the tank cap counterclockwise .
.,. Place the cap from above on the open fuel fille r
door ¢
fig. 261.
.,. Insert the fuel pump nozzle all the way into the
fuel filler neck.
.,. Begin fueling. Once the fuel pump nozzle turns
off the first time, the fuel tank is full. Do not
continue fueling, or else the expansion space in
the tank will be filled with fuel.

Checking and Filling
~ After the fuel pump has switched off, wait five seconds before removing it to allow the rest of
the fuel to finish dripping into the fuel tank.
~ Turn the fue l cap clockwise until you hear it
lock.
~ Close the fuel filler door and then press on the
left side until it latches .
The correct fuel type for your vehicle can be
found on a label located on the inside of the fuel
filler door. For additional information on fuel,
see
Qpage 314 .
For the tank capacity in your vehicle, refer to the
Technical Data
Qpage 382.
To reduce the risk of fuel leaking out or vapors
escaping, make sure that the fuel tank is closed
correctly. Otherwise
thP ¢..iff indicator light will
turn on.
If the centra l locking system malfunctions, the
fuel filler door may emergency release
Qpage317.
A WARNING
An improper fueling procedure and improper
handling of fuel can lead to explosions, fires,
severe burns and other injuries.
-Do not smoke and keep away from open
flames.
-The ignition must be switched off when re­
fueling.
-Cell phones, radio devices and other radio
equipment should always be switched off
when refueling. Electromagnetic 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
risk of electrostatic discharge that can cause
flying sparks. Sparks can start a fire when
refueling.

A WARNING
We recommend that you do not transport any
fuel 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, please note the following:
-Always place a fuel container on the
ground before filling. Never fill the fuel
container with fuel while it is in or on the
vehicle. Electrostatic charge can occur
while refueling and the fuel vapors could
ignite .
-For fuel containers made of metal, the
fuel pump nozzle must always maintain
contact with the container to reduce the
risk of static charge.
-Insert the fuel pump nozzle as far as pos­
sible into the filler opening while refuel­
ing.
-Follow legal requirements when using,
storing and transporting fuel containers.
-Make sure that the fuel container meets
the industry standards, for example ANSI
or ASTM F852-86.
@ Note
-Remove fuel that has overflowed onto any
vehicle components immediately to reduce
the risk of damage to the vehicle.
-Never drive until the fuel tank is completely
empty. The irregular supply of fuel that re­
sults from that can cause engine misfires.
Uncombusted fuel will enter the exhaust
system and increase the risk of damage to
the catalytic converter.
@I For the sake of the environment
Do not overfill the fuel tank, otherwise fuel
can leak out when the vehicle is warming up.
© Tips
The fuel filler door on your vehicle does not lock if you lock the vehicle from the inside us-
ing the central locking switch.

Checking and Filling
If the recommended engine oil is not available,
in an eme rg enc y you may add a maximum of 1
quart(! liter) of ACEA C3 or API SN engine oil
one tim e until the next oil change.
F or more information on the correct engine oil
for your vehicle, contact an authorized Audi dea l­
er or authorized Audi Service Facility . Have the oil
changed by an authori zed Audi dealer o r author­
ized Service Fac ility .

Checking the engine oil level
The engine oil dipstick varies depending on the
engine type .

p le )
Observe the safety precaut ions ¢.& in Working
in the engine compartment on page 318 .
.. Park your vehicle on a level surface.
.. Shut the engine off when it is warm .
.. Wait approx imately two m inutes .
.. Open the hood ¢ page 320 .
.. Remove the oi l dipstick¢ page 321, fig. 267,
wipe it off with a clean cloth and insert it a ll the
way in again .
.. Remove the o il dipstick again and then read the
oil
level ¢ table on page 322.
.. Add engine oil if necessary c:> page 323.

Areas on the o il dipstick 9 fig . 268 .
(D If the engine oil leve l is just before the
mark ing
(D , then engine oil must be added .
See¢@.
@ Do not add engine oil.
(D Note
- T he engine o il level must not be below the
ma rking
(D , because this increases the risk
of engine damage.
- After add ing engine oil, the oil leve l must
not be above the marking @, because this
increases the risk of catalytic converter and/
or engine damage . Do not start the engine .
Contact an authorized Audi dealer or au­
thorized Audi Service Facility to have excess eng ine oil extracted if necessary .
(D Tips
- The engine oil consumption may be up to
0.5 quart/600 miles (0.5 liter/1,000 km),
depending on driving style and operating
conditions. Consumpt io n may be h igher
dur ing the fi rst 3,000 mi les (5,000 km) . Be­
c ause of this , the eng ine o il level must be
che cked regularly.
It is best to check each
t ime you refuel your vehicle and before long
drives .
- In order to prov ide effective l ubrication and
cooling of interna l engine components, a ll
internal combustion engines consume a cer ­
tain amount of oil. O il consumption varies
from engine to engine and may change sig­ nificantly over the life of the engine. Typi­
cally, eng ines with a specif ied break-in peri­
od consume more oil during the break-in pe ­
riod than they consume after o il consump­
t ion has stabilized .
- Under normal condit ions, the rate of oil
cons umption depends on t he quality and
viscosity of the oil, the RPM (revo lutions per
mi nute) at which the engine is ope rated, the
ambien t temperature and road conditions .
Further factors are the amount of oi l dilu­
tion from water condensation or fuel resi­ due and the oxidation level of the oil. As any
eng ine is subject to wear as m ileage builds
