If you mix diesel fuel with petrol, the flash
point of this fuel mixture is lower than that of
pure diesel fuel. When the engine is running,
components in the exhaust system may over-
heat unnoticed. There is a risk of fire.
Never refuel with petrol. Never add petrol to
diesel fuel.

Do not use petrol to refuel vehicles with a

diesel engine. Do not use diesel to refuel
vehicles with a petrol engine. Do not switch
on the ignition if you accidentally refuel
with the wrong fuel. Otherwise, the fuel will
enter the fuel system. Even small amounts
of the wrong fuel could result in damage to
the fuel system and the engine. The repair
costs are high. Notify a qualified specialist
workshop and have the fuel tank and fuel
lines drained completely.

Overfilling the fuel tank could damage the

fuel system.

Take care not to spill any fuel on painted

surfaces. You could otherwise damage the
paintwork.

Use a filter when adding fuel from a fuel

can. The fuel lines and/or the diesel injec-
tion system could otherwise be blocked by
particles from the fuel can.

Do not get into the vehicle again during the
refuelling process. Otherwise, electrostatic
charge could build up again.
If you overfill the fuel tank, some fuel may
spray out when you remove the fuel pump
nozzle.
