Misfueling guard for diesel vehicles

Please first read and note the introductory information and heed the WARNINGS  
The fuel filler neck of diesel vehicles is equipped with a misfueling guard ⇒ꢀfig. 136. The misfueling  
guard helps prevent filling the fuel tank of a diesel vehicle with gasoline, because the guard makes it  
difficult to insert any type of filler nozzle other than the type commonly used for diesel fuel.  
Damaged, worn out, or incorrect nozzles, as well as other means of refueling (portable fuel containers,  
for example) will generally not open the misfueling guard and fuel from these sources cannot easily  
flow into the tank. Using these incorrect or non-standard nozzles to refuel your diesel vehicle can  
cause fuel spills, which can cause fires, explosions, burns, and other severe injuries.  
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.  
Do not refuel from devices other than correct, undamaged standard diesel fuel pump  
nozzles.  
Always stop refueling once the pump nozzle switches off so that the tank does not  
overflow.  
NOTICE  
It is your responsibility to put the right fuel in your vehicle and any damage that results  
from using the wrong fuel is not covered under the Emissions warranties or any other  
Volkswagen Limited Warranty.  
If you put any amount of the wrong 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.  
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.  
NOTICE  
Never force a fuel nozzle in the diesel misfueling guard. Forcing a fuel nozzle in the misfueling  
guard can damage it so that it can no longer help prevent misfueling.  
If you have problems inserting a diesel fuel nozzle, please check to make sure you are  
using the right kind of diesel fuel.  
If you must refuel with a non-standard diesel fuel nozzle, an adapter is available from  
Volkswagen to allow refueling. Contact an authorized Volkswagen dealer or authorized  
Volkswagen Service Facility for assistance. Only use an adapter approved by Volkswagen for  
your vehicle.
