Misfueling Safeguard Assistant (Cayenne Diesel)
The Cayenne Diesel is equipped with a Misfueling Safeguard Assistant. This device is designed so that the tank can only be filled using a diesel pump nozzle of the proper diameter.
The Misfueling Safeguard Assistant helps prevent filling the fuel tank of a diesel vehicle with gasoline, because the assistant makes it difficult to insert any type of filler nozzle other than the type commonly used for diesel fuel.
The Misfueling Safeguard Assistant can generally only be properly opened with a correct nozzle of the proper diameter 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 Safeguard Assistant.
