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 perform a
self test and attempt to start the
next time the vehicle is turned on.
Once the engine starts, normal
operation will continue. See Fuel
System Messages on page 5 43
and Service Vehicle Messages on
page 5 46.

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. 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.
