Driving and Operating
During EMM, a DIC message
displays to show the
EMM percentage complete.
If No 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
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
before another fuel maintenance
mode 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 Yes is selected, FMM will begin.
FMM will automatically continue at
each vehicle start until fresh fuel is
added.
If No is selected, the FMM Request
screen will appear when the vehicle
is next started. The FMM request
can be delayed for only one day.
