218 Fuel supply and filling your fuel tank
@ Tips
-Running your engine while refuelling
may cause vapors to escape or even
cause fue l to spill out of the tank. This
would then shut off the fuel nozzle be­
fore the tank is full.
- Do not refuel your vehicle w ith the igni­
tion switched on. The fuel gauge may
otherwise not indicate the correct fuel
level after refuelling.
- Diesel vehicles* are equipped with a die­
sel m isfueling protector. It allows the
vehicle to be fueled only w ith 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
protector . If this is the case, try turning
the nozz le before inserting it in the fue l
filler neck, use a different fuel pump or see your authorized Audi dealer or au­
thorized repair facility for assistance.
- The fuel filler flap of your vehicle is not
locked when you lock the vehicle from
the inside.
Fuel filler flap emergency release
You can open the fuel filler flap by hand if the
power locking system should fail.
