Maintenance Modes
Engine Maintenance Mode (EMM)
Engine Maintenance Mode (EMM)
runs the engine to keep it in good
working condition after
approximately six weeks of no or
very limited engine operation. EMM
will force the engine to run, even if
there is a charge to power the
vehicle. When EMM is needed, the
EMM Request screen appears on
the centre stack display at vehicle
start.
Fuel Maintenance Mode (FMM)
Fuel Maintenance Mode (FMM)
tracks average fuel age. Old fuel
can cause engine problems. If low
engine usage causes average fuel
age to exceed approximately
one year, FMM will run the engine to
use up the old fuel. The engine will
run until enough fresh fuel is added
to bring the average fuel age into an
acceptable range. Allowing more old
fuel to be used up by FMM and
adding a larger amount of fresh fuel
will maximise the length of time
before another fuel maintenance
mode is needed. During FMM the
engine may turn on and off. See
Maintenance Modes on page 9 17.
