Checking and Filling



the vehicle. Electrostatic discharge can oc-
cur while refueling and the fuel vapors
could ignite.
— When using fuel containers made of met-
al, the fuel pump nozzle must always re-
main in contact with the container to re-
duce the risk of static charge.
— Insert the fuel pump nozzle as far as pos-
sible into the filler opening while refuel-
ing.
— Follow the applicable legal regulations in
the country where you are driving when
using, storing and transporting fuel con-
tainers.
— 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 may enter the exhaust
system and increase the risk of damage to
the catalytic converter.
@ For the sake of the environment
— Do not overfill the fuel tank, or fuel could
leak out when the vehicle is warming up.
— Fuel should never enter the sewer system or
come into contact with the ground.
@) 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.
@ Tips
Your vehicle is equipped with a misfueling
guard. It allows the vehicle to be fueled only
with
the correct fuel pump nozzle.
—Aworn or damaged nozzle or a nozzle that
is too small may not be able to open the die-
sel misfueling guard. If this is the case, try
turning the nozzle before inserting it in the
fuel filler neck, use a different fuel pump, or
see an authorized Audi dealer or authorized
Audi Service Facility for assistance.
—The misfueling guard does not open when
adding fuel from a fuel container. When re-
fueling with a reserve canister, you must use
the funnel stored in the luggage compart-
ment > page 257.
@) Tips
Applies to: vehicles with plug-in hybrid drive
- When inserting the fuel pump nozzle, make
sure that you do not press on the fuel filler
door opener @) with the fuel pump nozzle.
See the label in the fuel filler door @)
> fig. 158. Otherwise, a valve will close in
the fuel filler neck and fueling will stop even
if the tank is not full.
— You must vent the tank system again if you
press on the fuel filler door opener. The fuel
pump nozzle can stay in the fuel filler neck
when doing this. Vent the tank system by
pulling the EN) switch in the driver's door
again.
— If the engine turned off because the fuel
level was too low, then you may need to re-
fuel with up to 4.0 gallons (15 liters) of fuel
in order for the vehicle to detect the new
fuel level. Otherwise, the engine may not
restart.
— Fuel can age and may lead to problems
when starting. Audi recommends replacing
the fuel in your vehicle within six months.
