180 Driving and Operating
Electric Mode
In Electric Mode, the vehicle does
not use fuel or produce tailpipe
emissions. During this primary
mode, the vehicle is powered by
electrical energy stored in the high
voltage battery. The vehicle can
operate in this mode until the
battery has reached a low charge.
There are some conditions when the
battery charge is high enough to
provide Electric Mode operation, but
the engine still runs. They are:
.Cold ambient temperatures.
. Hot or cold high voltage battery
temperatures.
. The hood being open or not
completely closed and latched.
. Certain high voltage battery fault
conditions.
. Engine Maintenance Mode or
Fuel Maintenance Mode
being run.
Extended Range Mode
When the vehicle reaches the end
of its electric range, it switches to
Extended Range Mode (ERM). In
this secondary mode, electricity is
produced by the fuel-powered
engine. This secondary source of
electric power extends the vehicle
range. Operation will continue in
ERM until the vehicle can be
plugged in to recharge the high
voltage battery and restore
Electric Mode.
The high voltage battery will
continue to provide some power and
work together with the engine to
provide peak performance when it is
required, such as driving up a steep
incline or for high acceleration
maneuvers. The battery will not be
charged nor will electric vehicle
range be restored by the engine. In either Electric Mode or Extended
Range Mode, when the hood is
open and the vehicle is moving at
low speed or stopped, the engine
will run without turning off if the
vehicle is on, except when the
electric drive unit is in N (Neutral).
The engine will turn off or remain off
at low vehicle speed in N (Neutral).
The high voltage battery is not
charged when this occurs. Under
these conditions, the high voltage
battery can still be discharged
based on the vehicle loads such as
A/C, or 12-volt loads.
In either Electric Mode or Extended
Range Mode, if there is a high
voltage battery fault, the engine may
run without turning off to generate
needed electricity. The malfunction
indicator lamp will turn on. See
Malfunction Indicator Lamp (Check
Engine Light)
0109.

Hold Mode is only available when
the vehicle is in Electric Mode. This
mode places the remaining battery
charge into a reserve for the driver
to use as desired. Selecting this
mode transitions the vehicle to
Extended Range Mode to maintain
the battery charge reserve.
Upon exiting Hold Mode, the
reserved battery charge becomes
available again and the vehicle
returns to Electric Mode. If the
transition is from Hold Mode directly
to Mountain Mode, the electric
range displayed adjusts for the
Mountain Mode charge reserve.
Hold Mode will not change normal
vehicle acceleration or braking
performance.
Press MODE to select Hold Mode.
Press MODE again to return to
Normal Mode and it becomes active
after three seconds.
Each time the vehicle is started, it
will return to Normal Mode.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 until the current charge is
depleted. 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 may stop running
after the self test is completed,
based on the current mode of
operation. SeeFuel System

Maintenance Modes
Engine Maintenance Mode (EMM)
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 not start until after a
short delay once shifted into
D (Drive). 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 up to one day.
If the EMM request was delayed for
one day, EMM will automatically
start the engine at the next vehicle
start. The engine will not start until
after a short delay once shifted into
D (Drive).
An EMM Notification screen will
appear in the center stack display.
If the vehicle is shut 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. SeePropulsion Power
Messages 0138.
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.
The engine will not start until after a
short delay once shifted into
D (Drive). 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.

When the system has calculated
that oil life has been diminished, it
indicates that an oil change is
necessary. A CHANGE ENGINE
OIL SOON message comes on.
Change the oil as soon as possible
within the next 1 000 km (600 mi).
It is possible that, if driving under
the best conditions, the oil life
system might indicate that an oil
change is not necessary for up to
two years. The engine oil and filter
must be changed at least once
every two years and, at this time,
the system must be reset. Your
dealer has trained service people
who will perform this work and reset
the system. It is also important to
check the oil regularly over the
course of an oil drain interval and
keep it at the proper level.
If the system is ever reset
accidentally, the oil must be
changed at 5 000 km (3,000 mi)
since the last oil change.
Remember to reset the oil life
system whenever the oil is changed.How to Reset the Engine Oil
