-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 F852-86).
(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.
@) For the sake of the environment
If the fuel nozzle is used correctly, it will ind i­
cate that the tank is full the first time it
sw itches off automatically. Do not try to add
more fuel, because it can spill over. Also, the
expansion space in the tank will fill, which can
result in fuel spilling out when it becomes
warm and polluting the environment.
@ Tips
Fuel can age and may lead to problems when
starting . Audi recommends replacing the fuel
in your vehicle within six months.
@ Tips
- If the engine is running while fueling, va­
pors can escape or the fuel can spill over.
Because of th is, the fuel nozzle switches off
before the tank is full.
- Do not fue l the vehicle when the ignition is
switched on . Otherwise, the fuel gauge may
not show the correct level after fueling the
vehicle.
Checking and Filling
-The fuel filler door on your vehicle does not
lock when you lock the vehicle from the in­
side.

Catalytic converter
Applies to: vehicles with gasoline engine

system (catalytic converter) is functioning prop­
erly to ensure that your vehicle is running in an
environmentally sound manner.
.. Always use lead-free gasoline c:> page 184, Gas­
oline grade .
