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
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.
• Selectable drive modes: Certain
selectable drive modes may cause the
engine to run. See What Is Drive Mode
Control (page 278).
• Live in Drive: Use of the paddle shifters
while in drive (D) may cause the engine
to run. See Automatic Transmission
(page
201).
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.

HYBRID VEHICLE FREQUENTLY ASKED QUESTIONS
Answer
Question
The high voltage battery is electrically isol-ated from the rest of the vehicle when the
key is off. When you switch the key on, high voltage contactors inside the battery are
closed to make the electricity available to the motor and generator and enable the
vehicle to drive. The clicks are the sound of these contactors as they close and open during start up and shut down.
What are the series of clicks from the cargo
area when I first turn the key in the ignition?
The vehicle's computer determines if an
engine start is required at key-on. Silent key starts the engine if it is necessary for cabin
heating, windshield defrost, or if the outside temperature is low.
Why does the engine sometimes start at
key-on?
There are several reasons the engine stayson for an extended amount of time when
you first start it. One common reason is to
make sure that the emissions components are warm enough to minimize tailpipe
emissions. As the climate gets cooler, this engine-on time is extended.
Why does it take a long time before the
engine shuts down?
In order to make sure that the climate
control system can begin heating the cabin
or defrosting the windshield as soon as you request it, the engine coolant temperature
has to be kept sufficiently hot. Keeping the
engine on is required to maintain the correct coolant temperature.
Why does my engine stay on when it is
extremely cold outside?
Your hybrid vehicle can use E15 fuel (15%ethanol, 85% gasoline), but you couldnotice slightly reduced fuel economy
because ethanol contains less energy per
gallon than gasoline. Your hybrid vehicle is not designed to use E85 (85% ethanol).
Can I put E15 or E85 in my vehicle, and how
will it affect my fuel economy?
The high voltage battery system is designedto last the life of the vehicle and requires no maintenance.
How long will my high voltage battery last?
Does it need maintenance?

Your vehicle may not pass the I/M test if
the service engine soon indicator is on or
not working properly (bulb is burned out),
or if the OBD-II system has determined
that some of the emission control systems
have not been properly checked. In this
case, the vehicle is not ready for I/M
testing.
If the vehicle
’s engine or transmission has
just been serviced, or the battery has
recently run down or been replaced, the
OBD-II system may indicate that the
vehicle is not ready for I/M testing. To
determine if the vehicle is ready for I/M
testing, turn the ignition key to the on
position for 15 seconds without cranking
the engine. If the service engine soon
indicator blinks eight times, it means that
the vehicle is not ready for I/M testing; if
the service engine soon indicator stays on
solid, it means that your vehicle is ready
for I/M testing.
The OBD-II system checks the emission
control system during normal driving. A
complete check may take several days.
If the vehicle is not ready for I/M testing,
you can perform the following driving cycle
consisting of mixed city and highway
driving:
1. 15 minutes of steady driving on an expressway or highway followed by 20
minutes of stop-and-go driving with at
least four 30-second idle periods.
2. Allow your vehicle to sit for at least eight hours with the ignition off. Then,
start the vehicle and complete the
above driving cycle. The vehicle must
warm up to its normal operating
temperature. Once started, do not turn
off the vehicle until the above driving
cycle is complete.
If the vehicle is still not ready for I/M
testing, you need to repeat the above
driving cycle.

Driving in Special Conditions With
Four-Wheel drive (4WD)
Note:
Use of the 4WD system in slippery,
deep snow, and sand drive modes on dry
surfaces could produce some vibration,
driveline bind up, or excessive tire wear as
these drive modes are intended for slippery
and loose surfaces.
Note: The design of 4WD vehicles are for
driving on sand, snow, mud and rough roads
and have operating characteristics that are
somewhat different from conventional
vehicles, both on and off the highway.
Basic Operating Principles in Special
Conditions
• Drive slower in strong crosswinds which
can affect the normal steering
characteristics of your vehicle.
• Be extremely careful when driving on
pavement made slippery by loose sand,
water, gravel, snow or ice. If Your Vehicle Goes Off the Edge of the
Pavement
•
If your vehicle goes off the edge of the
pavement, slow down, but avoid severe
brake application, ease the vehicle
back onto the pavement only after
reducing your speed. Do not turn the
steering wheel too sharply while
returning to the road surface.
• It could be safer to stay on the apron
or shoulder of the road and slow down
gradually before returning to the
pavement. You could lose control if you
do not slow down or if you turn the
steering wheel too sharply or abruptly.
• It often could be less risky to strike
small objects, such as highway
reflectors, with minor damage to your
vehicle rather than attempt a sudden
return to the pavement which could
cause the vehicle to slide sideways out
of control or rollover. Remember, your
safety and the safety of others should
be your primary concern.
If Your Vehicle Gets Stuck WARNING: Apply the parking
brake, shift into park (P), switch the
ignition off and remove the key before
you leave your vehicle. Failure to follow
this instruction could result in personal
injury or death. WARNING:
If the parking brake is
fully released, but the brake warning
lamp remains illuminated, the brakes
may not be working properly. Have your
vehicle checked as soon as possible. WARNING:
Do not spin the wheels
at over 34 mph (55 km/h). The tires may
fail and injure a passenger or bystander.

PRINCIPLE OF OPERATION
WARNING: To help avoid personal
injury, always use caution when in
reverse (R) and when using the sensing
system. WARNING:
The system may not
detect objects with surfaces that absorb
reflection. Always drive with due care
and attention. Failure to take care may
result in a crash. WARNING: Traffic control systems,
inclement weather, air brakes, external
motors and fans may affect the correct
operation of the sensing system. This
may cause reduced performance or false
alerts. WARNING:
The system may not
detect small or moving objects,
particularly those close to the ground.
Note: If your vehicle has MyKey ™, the
sensing system cannot be switched off
when a MyKey ™ is present.
See Principle
of Operation (page 64).
Note: Keep the sensors on the bumper or
fascia free from snow, ice and large
accumulations of dirt. If the sensors are
covered, the system ’s accuracy can be
affected. Do not clean the sensors with
sharp objects.
Note: If your vehicle sustains damage to
the bumper or fascia, leaving it misaligned
or bent, the sensing zone may be altered
causing inaccurate measurement of
obstacles or false alerts. Note:
Certain add-on devices installed
around the bumper or fascia may create
false alerts. For example, large trailer
hitches, bike or surfboard racks, license plate
brackets, bumper covers or any other device
that may block the normal detection zone
of the system. Remove the add-on device
to prevent false alerts.
Note: When you connect a trailer to your
vehicle, the rear parking aid may detect the
trailer and therefore provide an alert. Disable
the rear parking aid when you connect a
trailer to prevent the alert.
The sensing system warns the driver of
obstacles within a certain range of your
vehicle. The system turns on automatically
whenever you switch the ignition on.
You can switch the system off through the
touchscreen, information display or from
the pop-up message that appears once
you shift the transmission into reverse (R).
If your vehicle has a parking aid button, you
can switch the system off by pressing the
button.
If a fault is present in the system, a warning
message appears in the information
display. See Information Messages
(page 121).
REAR PARKING AID WARNING:
The system may not
detect objects with surfaces that absorb
reflection. Always drive with due care
and attention. Failure to take care may
result in a crash. WARNING:
The system may not
detect small or moving objects,
particularly those close to the ground.
