Refueling
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
still open the flap manually
-for detailed instruc­
tions see
¢page 319.
You can find the fuel tank capacity of your vehicle
in
¢page 381.
The label on the inside of the fuel filler flap tells
you the correct fuel for your vehicle. For more in­
formation about fuel specifications, see
<=?page 315.
Your veh icle fuel tank has an onboard refuelling
vapor recovery system. This feature he lps to pre­
vent fuel vapors from escap ing from the tank and
polluting the environment while you refuel your
vehicle . In order to fill the tank properly while
protecting the environment, please follow this
refueling procedure carefully.
A WARNING
Under normal operating conditions, never car­
ry additional fuel containers in your car. Gas
canisters and other containers used to trans­
port fuel can be dangerous. Such containers,
full or empty, may leak and could cause a fire
in a collision. If you must transport fuel to
use for your lawn mower, snow blower, etc.,
be very careful and always observe local and
state laws regarding the use, transportation
and storage of such fuel containers. Make cer­
tain the container meets industry standards
(ANSI/ASTM F8S2
-86).
(D Note
Never dr ive your vehicle until the fuel tank is
completely empty. The irregu lar supply of

fuel can cause misfiring. Gasoline could enter
the exhaust system and damage the catalytic
converter.

filler door. For additional information on fuel,
see
<=> page 315.
The fuel tank capacity of your vehicle is listed in
the
Technical Data section <=> page 381.
To avoid fuel spilling or evaporating from the fuel
tank always close fuel cap properly and com­
pletely . An improperly closed fuel filler cap may
also cause the MIL lamp
<=>page 24 to come on.
A WARNING
Not paying attention when fueling or han­
dling fuel incorrectly can lead to fires, explo­
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 nozzle
completely into the tank opening, fuel can
leak out or run over. Leaked fuel can ignite
and start a fire .
- Do not use the telephone while fueling. The
electromagnetic rays can cause sparks,
which can ignite fuel vapors and start a fire.
- Do not sit in your vehicle while fueling. If
you must make an exception and enter your
vehicle again while fueling, close the door and touch metal to discharge static electric­
ity before touching the fuel nozzle . Static
electricity can create sparks, which can ig­
nite vapors when fueling.
- Do not smoke or have an open flame in the
area when fueling your vehicle or filling a
fuel container because this increases the
risk of an explosion .
-For your safety , carrying fuel containers in
your vehicle is not recommended. Whether
full or empty, the container 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 ­
tricity is discharged when filling which can
cause the fuel vapors to ignite and in­
creases the risk of an explosion.
- Always place a fuel container on the
ground before filling.
318
-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 static 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 legal requirements when using, storing and transporting fuel containers .
-Make sure the fuel container conforms to
industry standards (ANSI/ASTM F8S2 -86).
{(D Note
- Remove spilled fuel from vehicle paint im­
mediately, because it can damage paint.
- 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.
- If the fuel tank runs completely empty in a
vehicle with a
diesel engine, the ignition
must remain switched on for at least 30
seconds after refueling before starting the
engine.
It may take longer than usual for
the engine to start, even up to a minute.
This is because the air must first bleed out
of the fuel system when starting the engine.
@ For the sake of the environment
Do not overfill the fuel tank, otherwise fuel
can leak out when the vehicle is warming up.
@ Tips
Diesel vehicles are equipped with a diesel mis­
fueling guard.
It allows the vehicle to be fu­
eled only 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 diesel
misfueling guard. If this is the case, try turn­
ing the nozzle before inserting it in the fuel
filler neck, use a different fuel pump, or see

Driving with an insufficient oil level is likely to
cause severe damage to the engine.
@ Tips
-The oil pressure warning display. is not
an indicator of the oil level. Do not rely on
it. Instead, check the oil level in your en­
gine at regular intervals, preferably each
time you refuel, and always before going
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 Audi
dealer to have the cause of your concern
properly diagnosed. Keep in mind that the
accurate measurement of oil consumption
requires great care 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 and adding
engine oil
The engine oil level can be checked in the Info ­
tainment system

-Switch only the ignition back on. Wait approxi-
mately two minutes so that the engine oil can
flow back into the oil pan .
Checking and Filling
- Select in the Infotainment system: the !MENUI
button > Vehicle > left control button > Service
& checks > Oil level.
-Check the oil level in the Infotainment system
display. Add engine oil if the bar in the oil level
indicator is just before "min".
Adding engine oil Follow the safety precautions
~&. in Working in
the engine compartment on page 323.
- Stop the engine and open the hood
~page 324 .
-Unscrew the cap~ on the engine oil filling
opening
~ fig. 269, Qpage 325.
- Carefully add O .S quart (O .S liter) of the correct
oil
~ page 325.
- Close the engine oil filler opening cap.
- Close the hood, restart the ignition after two
minutes and read the current oil level in the In ­
fotainment system.
A WARNING ...__ --When adding oil, do not let oil drip onto hot
engine components. This increases the risk
of afire.
-You must secure the cap on the oil filler
opening correctly so that oil does not leak
out onto the hot engine and exhaust system
when the engine is running, because this is
a fire hazard.
-Always clean skin thoroughly if it comes into
contact with engine oil.
0 Note
- The engine oil level must not be under the
"min" marking, because this increases the
risk of engine damage.
- If the message II Please reduce oil level
appears, there is too much oil in the engine
and there is a risk of damaging the catalytic
converter and engine. Do not start the en­
gine. Contact an authorized Audi dealer or
authorized Audi Service Facility to have ex­
cess engine oil extracted if necessary.
- Do not mix any additional lubricants into
the engine oil. Damage caused by such addi-
tives is not covered by the warranty.
