"FUEL LEVEL" indication
Suitable icons inform the rider of the quantity of fuel
in the tank.
This indication is only present if MENU 2 is active.
With MENU 2 active, if a level sensor error is
triggered, no matter the fuel level output or
calculated, as well as in case of CAN no frame or BUS-
Off, the display will still show the level icon in the
fixed status "off" (and sensor error warning will be
displayed as well).
