turning off. During EMM, a DIC
message displays to show the
EMM percentage complete.
If Postpone is selected, the EMM
Request screen will appear when
the vehicle is next started. The
EMM request can be delayed for
only one day.
If the EMM request was delayed for
one day, EMM will automatically
start the engine at the next vehicle
start. An EMM Notification screen
will appear in the center stack
display.
If the vehicle shuts off during EMM,
it will restart the next time the
vehicle is driven. A message
displays to indicate that EMM is
active.
If EMM is required and the fuel level
is low, EMM may eventually empty
the fuel tank if fuel is not added.
This will result in reduced, or no
power. An adequate fuel level must
be maintained in the vehicle to keep
it operational. See Propulsion Power
Messages on page 5-48.
Fuel Maintenance Mode (FMM)
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 maximize the length of time
Black plate (26,1)
before another FMM is needed.
During FMM the engine may turn on
and off.
When FMM is needed, the FMM
Request screen appears on the
center stack display at vehicle start.
If Start Maintenance is selected,
FMM will begin. FMM will
automatically continue at each
vehicle start until fresh fuel is
added.
If Postpone is selected, the FMM
Request screen will appear when
the vehicle is next started. The FMM
request can be delayed for only
one day.
