The misfueling guard can generally only be properly opened with a correct nozzle from a standard
diesel fuel pump. Under certain circumstances it may be necessary to turn the nozzle back and forth
slightly with light pressure to open the misfueling guard. If the misfueling guard cannot be opened this
way, see the nearest authorized Volkswagen dealer or authorized Volkswagen Service Facility and
have the fuel system checked.
WARNING
Spilled fuel can cause fires, explosions, burns, and other severe injuries.
x Do not refuel from devices other than correct, undamaged standard diesel fuel pump
nozzles.
x Always stop refueling once the pump nozzle switches off so that the tank does not
overflow.

NOTICE
x It is your responsibility to put the right fuel in your vehicle and any damage that results is
not covered under the Emissions warranties or any other Volkswagen Limited Warranty.
x If you put any amount of the incorrect fuel in the fuel tank, do not start the engine under any
circumstances. Immediately contact the nearest authorized Volkswagen dealer or authorized
Volkswagen Service Facility for assistance.
x If diesel fuel should get on any rubber hose, it must be wiped off immediately. The same
applies if diesel fuel gets onto other parts of the vehicle, especially paint, tires, or a plastic
part. Wash the contaminated vehicle parts right away with soap and warm water to help
prevent leaks and serious damage.
x Never force a fuel nozzle in the misfueling guard. If you have problems inserting a fuel
nozzle, first check to make sure you are using the correct diesel fuel. If you are, go to a pump
with the standard diesel nozzle. Forcing a fuel nozzle in the misfueling guard can damage it so
that it can no longer help prevent misfueling.
