An adequate fuel level mustbe maintained in the vehicle to keepit operational. See Propulsion PowerMessages on page 5-48.Fuel Maintenance Mode (FMM)FMM tracks average fuel age. Oldfuel can cause engine problems.If low engine usage causes averagefuel age to exceed approximatelyone year, FMM will run the engine touse up the old fuel. The engine willrun until enough fresh fuel is addedto bring the average fuel age into anacceptable range. Allowing more oldfuel to be used up by FMM andadding a larger amount of fresh fuelwill maximize the length of timebefore another FMM is needed.During FMM the engine may turn onand off.
