The fuel filler neck of diesel vehicles is equipped with a misfueling guard ⇒ fig. 278. 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.
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.
Fuel capacities
.
In vehicles with selective catalytic reduction, a special urea solution (AdBlue) is injected into the
exhaust system ahead of the catalytic converter in order to reduce nitrogen oxide emissions.
AdBlue is stored in a separate tank of the vehicle and should be refilled under normal driving
conditions during service according to the maintenance schedule. The AdBlue tank holds slightly less
than 5 gallons (20 liters).
AdBlue consumption depends on the individual driving style, system operating temperature, and
outside air temperature. Therefore in rare cases AdBlue may have to be refilled between service
events.
Starting with a remaining range of about 1500 miles (2400 km), a reminder to refill AdBlue is displayed
in the instrument cluster. If you ignore the last refill reminder, it is impossible to start the engine again
after it is switched off
Volkswagen recommends that you have the AdBlue tank refilled by an authorized Volkswagen dealer
or an authorized Volkswagen Service Facility. If no authorized Volkswagen dealer or authorized
Volkswagen Service Facility or other qualified workshop is available, you should refill at least 1.5
gallons (5.7 liters) of AdBlue (3 AdBlue bottles). Refill only the type of AdBlue that Volkswagen has
explicitly approved for your vehicle.
If warning lights ~ and d both come on together, there is a malfunction. Volkswagen recommends that
you take the vehicle to the closest qualified workshop.

United States, Germany, the European Union and in other countries.
