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 aqualified specialist
workshop and have the fuel tan kand 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
