Important Ventilating Information
If you stop your vehicle and then leave the
engine idling for long periods of time, we
recommend that you do one of the following:
• Open the windows at least 1 in (3 cm).
• Set your climate control to outside air.
ENGINE BLOCK HEATER (IF EQUIPPED)
WARNING: Failure to follow engine
block heater instructions could result in
property damage or serious personal
injury.
WARNING: Do not use your heater
with ungrounded electrical systems or
two-pronged adapters. There is a risk of
electrical shock.
WARNING: Do not fully close the
hood, or allow it to drop under its own
weight when using the engine block
heater. This could damage the power cable
and may cause an electrical short resulting
in fire, injury and property damage.
Note:The heater is most effective when
outdoor temperatures are below 0°F (-18°C).
213
Starting and Stopping the Engine

The heater acts as a starting aid by warming
the engine coolant. This allows the climate
control system to respond quickly. The
equipment includes a heater element
(installed in the engine block) and a wire
harness. You can connect the system to a
grounded 120-volt AC electrical source.
We recommend that you do the following for
a safe and correct operation:
• Use a 16-gauge outdoor extension cord
that is product certified by Underwriter’s
Laboratory (UL) or Canadian Standards
Association (CSA). This extension cord
must be suitable for use outdoors, in cold
temperatures, and be clearly marked
Suitable for Use with Outdoor
Appliances. Do not use an indoor
extension cord outdoors. This could
result in an electric shock or become a
fire hazard.
• Use as short an extension cord as
possible.
• Do not use multiple extension cords.• Make sure that when in operation, the
extension cord plug and heater cord plug
connections are free and clear of water.
This could cause an electric shock or fire.
• Make sure your vehicle is parked in a
clean area, clear of combustibles.
• Make sure the heater, heater cord and
extension cord are firmly connected.
• Check for heat anywhere in the electrical
hookup once the system has been
operating for approximately 30 minutes.
• Make sure the system is unplugged and
properly stowed before starting and
driving your vehicle. Make sure the
protective cover seals the prongs of the
block heater cord plug when not in use.
• Make sure the heater system is checked
for proper operation before winter.
Using the Engine Block Heater
The engine block heater receptacle terminals
are located on the left side of the engine
compartment.Make sure the receptacle terminals are clean
and dry prior to use. Clean them with a dry
cloth if necessary.
The heater uses 0.4 to 1.0 kilowatt-hours of
energy per hour of use. The system does not
have a thermostat. It achieves maximum
temperature after approximately three hours
of operation. Using the heater longer than
three hours does not improve system
performance and unnecessarily uses
electricity.

HYBRID VEHICLE OPERATION
This hybrid vehicle combines electric and
gasoline propulsion to provide breakthrough
performance and improved efficiency.
Familiarizing yourself with these unique
characteristics provides an optimal driving
experience from your vehicle.
Starting
E293827
When you start your vehicle, a
green READY indicator light
appears in the instrument cluster
letting you know that your vehicle is ready
for driving.
The engine may not start because your
vehicle has a silent key start feature. This
fuel saving feature allows your vehicle to be
ready to drive without requiring the gas
engine to be running. The indicator remains
on when your vehicle is on, whether the
engine is running or not, to indicate your
vehicle is capable of movement using the
electric motor, gas engine or both. Typically,
the engine does not start unless the vehicle
is cold, a climate control change is requested
or you press the accelerator pedal.
Driving
The gas engine automatically starts and
stops to provide power when needed and
to save fuel when not needed. When
coasting at low speeds, coming to a stop, or
standing, the gas engine normally shuts
down and your vehicle operates in
electric-only mode.
Conditions that may cause the engine to start
up or remain running include:
• Considerable vehicle acceleration.
• Climbing a hill.
• Charge level of high voltage battery is
low.
• High or low outside temperatures in
order to provide system heating or
cooling.
• Engine not warm enough to provide
passenger requested cabin temperature.
• Towing a trailer.
217
Unique Driving Characteristics

• Selectable drive modes: Certain
selectable drive modes may cause the
engine to run. See What Is Drive Mode
Control (page 343).
• Live in Drive: Use of the paddle shifters
while in drive (D) may cause the engine
to run. See Automatic Transmission
(page 259).
Stopping
The gas engine may shut off to conserve fuel
as you come to a stop. Restarting your
vehicle is not required. Simply step on the
accelerator when you are ready to drive.
Transmission Operation
The engine and electric motor together
propel the vehicle through the automatic
transmission. This is normal hybrid operating
and helps deliver fuel efficiency and
performance.
Battery
Your hybrid is equipped with a high voltage
battery. A cool battery maintains battery life
and provides the best possible performance.
The high voltage battery is cooled by the
vehicle's air conditioning system. When the
air conditioning system is on, you may notice
a slight increase in air temperature coming
from the climate control vents while the
battery is cooling. You may also notice cool
air flowing from the vents when the air
conditioning or blower is off.
Braking
Your hybrid is equipped with standard
hydraulic braking and regenerative braking.
Regenerative braking is performed by your
transmission and it captures brake energy
and stores it in the high voltage battery.You may also notice during extending
downhill driving that your engine continues
to run instead of shutting off. During this
engine braking, the engine stays on, but it is
not using any fuel. You may also hear a slight
whine or whistle when operating your
vehicle. This is the normal operation of the
electric motor in the hybrid system.
Driving to Optimize Fuel Economy
Note:Having your engine running is not
always an indication of inefficiency. In some
cases, it is actually more efficient than
driving in electric mode.
Your fuel economy should improve
throughout your hybrid's break-in period. As
with any vehicle, your driving habits and
accessory usage can significantly impact
your fuel economy. For best results, keep
these tips in mind:
218
Unique Driving Characteristics

• Keep the tires properly inflated and only
use the recommended size.
• Aggressive driving increases the amount
of energy required to move your vehicle.
In general, you can achieve better fuel
economy with mild to moderate
acceleration and deceleration. Moderate
braking is particularly important since it
allows you to maximize the energy
captured by the regenerative braking
system.
Additional Tips:
• Do not carry extra loads.
• Be mindful of adding external
accessories that may increase
aerodynamic drag.
• Observe posted speed limits.
• Perform all scheduled maintenance.
• There is no need to wait for your engine
to warm up. The vehicle is ready to drive
immediately after starting.PLUG-IN HYBRID VEHICLE
OPERATION
Regularly plug in your vehicle to get optimal
electric-only range capability from the high
voltage battery. Charging your vehicle adds
electrical energy. This energy propels the
vehicle.
Estimated electric-only driving range shows
in blue next to the gasoline range on the
information display.
The system maximizes the use of
electric-only operation in normal drive mode.
System conditions could require the engine
to operate, however, the system uses the
available electric range whenever possible.
In Pure EV drive mode, your vehicle only
uses electric power unless you enable the
engine, or system conditions require the
engine to operate.Preserve EV drive mode saves the electric
range for later use. If you select this mode
and the battery is at full or near full charge,
it uses some electric-only range to discharge
the battery. This allows the regenerative
braking system to fully operate. If the battery
charge is low when selecting Preserve EV
mode, the engine charges the high voltage
battery to a minimum level. This provides
additional electric driving range. When the
battery charges to this level, Preserve EV
saves the electric range for later use.
Other drive modes appropriately make use
of electric power to help deliver the selected
drive mode experience. It could use available
electric-only range, if needed. See What Is
Drive Mode Control (page 343).
