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 refueling from a fuel can.
Otherwise, the fuel lines and/or injection sys-
tem could be blocked by particles from the
fuel can.
If you overfill the fuel tank, pressure may build
up in the fuel tank. This could cause fuel to spray
out when the fuel pump nozzle is removed.
There is a risk of injury. The fuel tank is full when
the fuel pump nozzle first switches off. End the

refueling process.
