The vehicle returns to Normal Mode
at each start to maintain a smaller
battery charge reserve for normal
driving.
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.

Electric Parking Brake
The vehicle has an Electric Parking
Brake (EPB). The
Yswitch is
on the center stack. The EPB can
always be activated, even if the
vehicle is off. To prevent draining
the 12‐volt battery, avoid repeated
cycles of the EPB system when
the vehicle is off.
In case of insufficient electrical
power, the EPB cannot be applied
or released.
Before leaving the vehicle, check
the Electric Parking Brake Light to
ensure the parking brake is applied.
EPB Apply
The EPB can be applied anytime
the vehicle is stopped. The EPB is
applied by momentarily lifting up on
the
Yswitch. Once fully applied,
the Electric Parking Brake Light will
be on. While the brake is being
applied, the Electric Parking Brake
Light will flash until full apply is
reached. If the light does not come
on, or remains flashing, have the
vehicle serviced. Do not drive the
vehicle if the Electric Parking Brake
Light is flashing. See your dealer.
If the EPB is applied while the
vehicle is in motion, a chime will
sound, and the DIC message
RELEASE PARKING BRAKE
will be displayed. The vehicle
will decelerate as long as the
switch is held in the up position. Releasing the
Yswitch during the
deceleration will release the parking
brake. If the
Yswitch is held in
the up position until the vehicle
comes to a stop, the EPB will
remain applied.
If the Electric Parking Brake Light
flashes continuously, the EPB is
only partially applied or released,
or there is a problem with the EPB.
The DIC message SERVICE
PARKING BRAKE will be displayed.
If this light flashes continuously,
release the EPB, and attempt to
apply it again. If this light continues
to flash, do not drive the vehicle.
See your dealer.
If the Service Electric Parking Brake
Light is on, the EPB has detected a
system problem and is operating
with reduced functionality.

Regenerative Braking
Regenerative braking takes some of
the energy from the moving vehicle
and turns it back into electrical
energy. This energy is then stored
back into the high voltage battery
system, contributing to increased
energy efficiency.
The hydraulic disc brakes work with
the regenerative braking to ensure
effective braking, such as when a
high braking demand is requested.
The braking system is
computer controlled and
blends the regenerative braking
with the conventional hydraulic disc
brakes to meet any requirements
for deceleration. The controllerinterprets the braking request
and uses regenerative braking,
conventional hydraulic braking, or a
combination of both as necessary.
Because the controller applies the
hydraulic brakes through its high
pressure accumulator, you may
occasionally hear the motor‐driven
pump when it recharges the system.
This is normal.
See
Warning Lights, Gauges,
and Indicators on page 5‑9 and
Driver Information Center (DIC) on
page 5‑43. In the event of a
controller problem, the brake pedal
may be harder to push and the
stopping distance may be longer.
Ride Control Systems
Traction Control
System (TCS)
The vehicle has a Traction Control
System (TCS) that limits wheel
spin. The system operates if it
senses that one or both of the drive
wheels are spinning or beginning to
lose traction. When this happens,
the system brakes the spinning
wheel(s) and/or reduces power
to limit wheel spin.
The system may be heard or felt
while it is working, but this is
normal.
To assist with directional control
of the vehicle, TCS comes on
automatically whenever the vehicle
is started and cannot be turned off.

Charging
Plug-In Charging
This section explains the process
for charging the vehicle's high
voltage battery. Do not allow the
vehicle to remain in temperature
extremes for long periods without
being driven or plugged in. It is
recommended that the vehicle
be plugged in when temperatures
are below 0°C (32°F) and above
32°C (90°F) to maximize high
voltage battery life.
The charging system may run fans
and pumps that result in sounds
from the vehicle while it is turned
off. Additional unexpected clicking
sounds may be experienced caused
by the electrical devices used while
charging.

A portable charge cord used to
charge the vehicle high voltage
battery is stored under the rear
luggage compartment.
The charge cord used to charge the
vehicle is a high‐powered electrical
device. During normal operation, the
AC wall plug of the charge cord may
feel warm. The AC wall plug must fit
tightly into an AC outlet that is in
good condition.
{WARNING
Using the charge cord with a
worn or damaged AC outlet
may cause burns or start a fire.
Periodically, check the AC wall
plug and charge cord while the
vehicle is charging. If the AC wall
plug feels hot, unplug the charge
cord and have the AC outlet
replaced by a qualified electrician.
Replace the charge cord if the AC
wall plug or cord are damaged.
Do not use an AC outlet that is
worn or damaged.
{WARNING
An extension cord should not
be used to charge the vehicle.
Use of an extension cord may
increase the risk of electric
shock or other hazards.
If an extension cord is used
because of limited access
to 120V AC power, use the
following safeguards:
The 120V AC outlet should be
GFCI protected.
The extension cord should be:
.GFCI protected.
.12 or 14 gage, 3 conductor.
.Rated for outdoor.
Charge Cord Status Indicators
The charge cord status indicators
illuminate green or flashing red to
identify the charge cord status.
When both indicators are green,
the vehicle can be charged. If any
indicators are flashing red, the

This level is
recommended. All four charge
level indicators will be lit.
Reduced Level: Use when the
electrical current is limited. Two
charge level indicators will be lit.
Vehicle Plug
The vehicle plug attaches to the
charge port on the vehicle. There
is a flashlight built into the vehicle
plug that can be used by squeezing
the vehicle plug lever. The flashlight
will turn off when the connection is
complete and the lever is released.
Electrical Requirements
for Battery Charging
The AC outlet must have a
grounded, dedicated, 15 amp or
greater, three‐prong wall plug.
That means there should be no
other major appliances connected
to the same circuit. If it is not a
dedicated circuit, the current rating
of the outlet circuit breaker could
be exceeded and cause it to trip
or open. The vehicle can be
charged in the reduced level mode.
See “Charge Level Button” in this
section. Reduced level mode allows
a non‐dedicated circuit to be used
but increases the charging time.
This vehicle is capable of being
charged with a variety of standard
vehicle charging equipment.

supplied power.
Fuel
Use of the recommended fuel
is an important part of the proper
maintenance of this vehicle.
To help keep the engine clean
and maintain optimum vehicle
performance, we recommend
the use of gasoline advertised as
TOP TIER Detergent Gasoline.
Look for the TOP TIER label on
the fuel pump to ensure gasoline
meets enhanced detergency
standards developed by auto
companies. A list of marketers
providing TOP TIER Detergent
Gasoline can be found at
www.toptiergas.com.
Use premium unleaded gasoline
with a posted octane rating of 91
or higher. If the octane is less than
91, you could damage the engine.
If heavy knocking is heard when
using gasoline rated at 91 octane
or higher, the engine needs service.
