Tips

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 veh icle with the igni-
tion switched on . The fuel gauge may
otherwise not indicate the correct fuel
level afte r refuelling.
- Diesel veh icles * are equipped with a die-
se l m isf ueling protector. It allows the
vehicle to be fueled on ly with a diesel
fuel pump nozzle . A wo rn o r damaged
nozzle or a nozz le t hat is too small may
not be able to open the d iesel misfueling
protector. If this is t he 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 repa ir facility for assistance.

locked when you lock the vehicle from
