Electric Vehicle
Operating Modes
System Operation
This vehicle is an Extended Range
Electric Vehicle (EREV). It uses an
electric propulsion system to drive
the vehicle at all times. Electricity is
the vehicle's primary source of
energy, while gasoline is the
secondary source.
The vehicle has two modes of
operation: Electric and Extended
Range. In Electric Mode, the vehicle
is propelled by its electric drive unit
only. It converts electrical energy
into mechanical energy to drive the
wheels. In Extended Range Mode,
both the battery and the engine
power the vehicle. The vehicle's
performance remains nearly the
same in either mode. See Driving
for Better Energy Efficiency 026.

9807421) - 2017 - CRC - 11/18/15
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.

9807421) - 2017 - CRC - 11/18/15
Driving and Operating 183
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
Messages 0135 andService
Vehicle Messages 0139.
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.

Driving and Operating 185
If the FMM request was delayed for
one day, FMM will start at the next
vehicle start and display the FMM
Notification screen on the center
stack display. The engine will not
start until after a short delay once
shifted into D (Drive).
If FMM is required and the fuel level
is low, FMM 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. After FMM has
run it is recommended to fill the
fuel tank.
Engine Exhaust
{Warning
Engine exhaust contains carbon
monoxide (CO) which cannot be
seen or smelled. Exposure to CO
can cause unconsciousness and
even death.
Exhaust may enter the vehicle if:
. The engine is running in
Extended Range Mode in
areas with poor ventilation
(parking garages, tunnels,
or deep snow that may
block underbody airflow or
tail pipes).
. The exhaust smells or
sounds strange or different.
. The exhaust system leaks
due to corrosion or damage.
. The vehicle exhaust system
has been modified,
damaged, or improperly
repaired.
(Continued)
Warning (Continued)
.There are holes or openings
in the vehicle body from
damage or aftermarket
modifications that are not
completely sealed.
If unusual fumes are detected or
if it is suspected that exhaust is
coming into the vehicle: . Drive it only with the
windows completely down.
. Have the vehicle repaired
immediately.
Never park with the engine
running in Extended Range Mode
in an enclosed area such as a
garage or a building that has no
fresh air ventilation.

The vehicle has an Electric Parking
Brake (EPB). The EPB can always
be activated, even if the vehicle
is off.
The system has a red parking brake
status light and an amber parking
brake warning light. SeeElectric
Parking Brake Light 0111 and
Service Electric Parking Brake Light
0 112. There are also parking
brake-related Driver Information
Center (DIC) messages. See Brake
System Messages 0133. In case of
insufficient electrical power, the EPB
cannot be applied or released.
Before leaving the vehicle, check
the red parking brake status light to
ensure that the parking brake is
applied.
EPB Apply
To apply the EPB:
1. Be sure the vehicle is at a complete stop.
2. Pull the EPB switch momentarily. The red parking brake status light
will flash and then stay on once the
EPB is fully applied. If the red
parking brake status light flashes
continuously, then the EPB is only
partially applied or there is a
problem with the EPB. A DIC
message will display. Release the
EPB and try to apply it again. If the
light does not come on, or keeps
flashing, have the vehicle serviced.
Do not drive the vehicle if the red
parking brake status light is flashing.
See your dealer. See
Electric
Parking Brake Light 0111.
If the amber parking brake warning
light is on, lift up on the EPB switch
and hold it up. Continue to hold the
switch until the red parking brake
status light remains on. If the amber
parking brake warning light is on,
see your dealer.
If the EPB is applied while the
vehicle is moving, the vehicle will
decelerate as long as the switch is
held up. If the switch is held up until
the vehicle comes to a stop, the
EPB will remain applied. The vehicle may automatically apply
the EPB in some situations when
the vehicle is not moving. This is
normal, and is done to periodically
check the correct operation of the
EPB system.
If the EPB fails to apply, the rear
wheels should be blocked to
prevent vehicle movement.
EPB Release
To release the EPB:
1. Place the vehicle in ON/RUN.
2. Apply and hold the brake pedal.
3. Push momentarily on the EPB switch.
The EPB is released when the red
parking brake status light is off.
If the amber parking brake warning
light is on, release the EPB by
pushing down on the EPB switch
and holding it down. Continue to
hold the switch until the red parking
brake status light is off. If either light
stays on after release is attempted,
see your dealer.

The controller interprets the braking
request and uses regenerative
braking, conventional hydraulic
braking, or a combination of both as
necessary.
The brake controller applies the
hydraulic brakes using a pump. The
pump may be heard during some
braking, such as rapid applies. This
is normal.
SeeWarning Lights, Gauges, and
Indicators 0101 andDriver
Information Center (DIC) 0130.
If there is a controller problem, the
brake pedal may be harder to push
and the stopping distance may be
longer.Regen on Demand®
Regen on Demand allows increased
deceleration by pressing and
holding the steering wheel paddle.
It works in D (Drive) and L (Low).
The accelerator pedal must be fully
released for it to work. The brake pedal must be applied at
low speed, because Regen on
Demand will not bring the car to a
full stop.
Cruise control will turn off, and the
brake lights may come on, when
this feature is activated.
The brake controller applies the
hydraulic brakes using a pump. You
may hear the pump during some
braking maneuvers, such as rapid
brake applies or while replacing any
regenerative brake torque as the
vehicle comes to a stop. This is
normal operation.
