Out of Fuel/Engine

Unavailable

If the vehicle runs out of fuel,
or the engine will not start due
to a malfunction, the vehicle can
continue to be driven in Electric
Mode. The vehicle will have
less responsive acceleration.
DIC messages indicate reduced
propulsion power, that the engine
is not available, and the need for
fuel or service.
Once the vehicle is refueled, or the
malfunction is corrected, the engine
will start the next time the vehicle is
turned on to perform a self test, and
DIC messages will not be displayed.
Once the engine starts successfully,
normal operation will continue in
either Electric or Extended Range
Mode. The engine will stop running
after the self test is completed,
and based on the current mode
of operation. See Fuel System
Messages on page 5 48 and
Service Vehicle Messages on
page 5 51.

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 center stack display at
vehicle start.
If Yes is selected, EMM will begin.
The engine will run for a set
amount of time without turning off.
