Your van runs on Diesel and does not drive without AdBlue (=DEF). Please pay attention to the display! What is AdBlue and why do I need to refill it?
You can fill up the tanks via the openings at the side of the driver´s door.
Above you can see the diesel tank and below the AdBlue tank (smaller, blue lid):
To open the diesel tank you will need the vehicles keys.
AdBlue
The on-board computer also tells you when the AdBlue level is low. A message appears together with this symbol:
Attention!
Make sure that you do not fill diesel into the water tank at the back!
Do not confuse the diesel tank with the AdBlue tank when refuelling!
Please note that both the diesel tank and the AdBlue tank should be completely full when you return your Roadsurfer.
