• Press on the fue l filler door to open
-arrow- ~fig.182. Your vehicle comes with a
new tank system witho ut a cap.
• Inse rt the fuel pump nozz le all the way into the
tank fi ller neck
~ fig . 183. Make sure it is cor­
rectly locked in place.
• Begin fueling. Once the pump no zzle switches
off, the fuel tank is "full" . Do no t fill the tank
more . Otherwise the expansion space in the
tank w ill be filled .
• Pu ll the pump nozz le out of the tank filler neck
five seconds after it has switched off, so that
the rest of the f uel can flow o ut of the pump
nozzle into the filler neck .
• Close fuel filler door until it latches.
The correct f uel type for your vehicle can be
found on a label located on the inside of the fue l
fi ller door. For additiona l info rmation on fuel,

A WARNING
Fuel ignites easily and can cause serious burns
and other injuries.
- Do not smoke or have an open flame in the
area whe n fueling your vehicle or filling a
fuel conta iner because this increases the
risk of an explosion .
- Follow legal requirements when using, stor­
ing a nd transporting fuel containers .
- For safety reasons, we recommend not car­
rying fuel containers. The conta iner could be
damaged in an accident and leak fuel.
- If you must transport fuel in a fuel contain­
er, note the following:
- Never fill the fuel container with fue l
while it is in or on the vehicle. Static e lec ­
tricity is discharged when fi lling which can
cause the fuel vapors to ignite and in­
creases the risk of an exp losion. A lways
place the conta iner on the ground when
fill ing it .
- The fuel pump nozzle must be inserted as
far as possible into the filler opening on
the fuel container .
- If the fuel container is made of metal, the
fuel nozzle must always be in contact with
the container when filling it with f uel. Th is
prevents static electricity from discharg­
ing .
-Never spill fuel in the vehicle or the l ug­
gage compartment. Evaporated fuel is ex­
plosive and increases the ris k of se rious in­
ju ry o r dea th .
(D Note
- Remove spilled fue l from veh icle pa int im­
media tely, because it ca n damage paint .
- Never drive unt il the fuel tank is completely
empty . The irregular supply of fue l that re­
sults from that can cause eng ine misfires.
Uncombus ted fuel will ente r the exh aus t
system and increase the risk of damage to
the cata lytic converter.
@) For the sake of the environment
Do not overfill the fuel tan k, otherwise f uel
can leak o ut when the veh icle is warming up.

(D Tips
- Your vehicle is equipped with a misfueling
guard. It allows the veh icle to be fueled on­
l y w ith the correct fuel pump nozzle .
- A worn or damaged nozzle or a nozz le that
i s too sma ll may not be ab le to open the
diesel misfueling guard. If this is the case,
try turning the nozzle before insert ing it in
the fue l filler neck, use a different fuel
pump, o r see an autho rized Aud i dea ler or

and have the cooling system inspected. If the
cooling system is not leaking, a loss can come
from the coolant boiling through overheating
and being pushed out of the cooling system.
A WARNING
The cooling system is pressurized and can be­
come very hot . To reduce the risk of burns
from hot coolant:
- Do not open the coolant expansion tank cap when the eng ine is hot. This increases the
risk of burns.
- Stop the engine and allow it to cool.
- Protect your face, hands and arms from es-
caping coolant and steam by covering the
coolant tank cap with a large, thick cloth .
- Turn the coolant tank cap counterclockwise
slowly and keep light pressure on the cap .
- To reduce the risk of burns, do not allow any
antifreeze or coolant to drip onto the ex­
haust system or hot engine components .
The ethylene g lycol in engine coolant can
catch fire under certain circumstances.
- The coolant add itive and the coolant can be
dangerous to your health. For this reason,
keep the coolant in the original container
and away from children. There is a risk of
poisoning.
- When working in the engine compartment,
remember that the radiator fan can sw itch
on even if the ignition is switched off, which
increases the risk of injury.
(D Note
Do not add coolant if the expansion tank is
empty . Air could enter the cooling system and
damage the engine. If this is the case, do not
cont inue driving. See an authorized Audi deal­
er or authorized Audi Service Facility for assis­
tance.
