GENERAL INFORMATION ON
RADIO FREQUENCIES
This device complies with Part 15 of the
FCC Rules and with Industry Canada
license-exempt RSS standard(s).
Operation is subject to the following two
conditions: (1) This device may not cause
harmful interference, and (2) This device
must accept any interference received,
including interference that may cause
undesired operation.
WARNING: Changes or
modifications not expressively approved
by the party responsible for compliance
could void the user's authority to operate
the equipment. The term "IC:" before the
radio certification number only signifies
that Industry Canada technical
specifications were met.
The typical operating range for your
transmitter is approximately
33 ft (10 m).
Vehicles with the remote start feature will
have a greater range.
One of the following could cause a
decrease in operating range:
• Weather conditions.
• Nearby radio towers.
• Structures around the vehicle.
• Other vehicles parked next to your
vehicle.
The radio frequency used by your remote
control can also be used by other radio
transmitters, for example amateur radios,
medical equipment, wireless headphones,
wireless remote controls, cell phones,
battery chargers and alarm systems. If the
frequencies are jammed, you will not be
able to use your remote control. You can
lock and unlock the doors with the key.
Note: Make sure to lock your vehicle before
leaving it unattended. Note:
If you are in range, the remote control
will operate if you press any button
unintentionally.
Note: The remote control contains sensitive
electrical components. Exposure to moisture
or impact may cause permanent damage.
Intelligent Access
(If Equipped)
The system uses a radio frequency signal
to communicate with your vehicle and
authorize your vehicle to unlock when one
of the following conditions are met:
• You activate the front exterior door
handle switch.
• You press the luggage compartment
button.
• You press a button on the transmitter.
If excessive radio frequency interference
is present in the area or if the transmitter
battery is low, you may need to
mechanically unlock your door. You can
use the mechanical key blade in your
intelligent access key to open the driver
door in this situation. See
Remote
Control (page 57).
REMOTE CONTROL
Integrated Keyhead Transmitter
Use the key blade to start your vehicle and
unlock or lock the driver door from outside
your vehicle. The integrated keyhead
transmitter functions as a programmed
ignition key that operates all the locks and
starts your vehicle, as well as a remote
control.

*This method only works for vehicles with
the hands-free liftgate feature.
Setting the Liftgate Open Height
1. Open the liftgate.
2.
Stop the liftgate movement by pressing
the control button on the liftgate when
it reaches the desired height.
Note: Once the liftgate has stopped
moving, you can also manually move it to
the desired height.
3. Press and hold the liftgate control button on the liftgate until you hear a
tone, indicating programming is
complete.
Note: You can only use the liftgate control
button to program the height.
Note: You cannot program the height if the
liftgate position is too low.
The new open liftgate height is recalled
when the power liftgate is opened. To
change the programmed height, repeat the
above procedure. Once you open the
power liftgate, you can manually move it
to a different height.
Note: The system recalls the new
programmed height until you reprogram it,
even if you disconnect the battery.
When operating the power liftgate after
you have programmed a lower height than
fully open, you can fully open the liftgate
by manually pushing it upward to the
maximum open position. Obstacle Detection
Note:
Entering your vehicle while the
liftgate is closing can cause your vehicle to
bounce and activate obstacle detection. To
prevent this, let the power liftgate close
completely before you enter your vehicle.
Before driving off, check the instrument
cluster for a liftgate or door ajar message or
warning indicator. Failure to do this could
result in unintentionally leaving the liftgate
open while driving.
When Closing
The system stops when it detects an
obstacle. A tone sounds and the system
reverses to open. Once you remove the
obstacle, you can power close the liftgate.
When Opening
The system stops when it detects an
obstacle and a tone sounds. Once you
remove the obstacle, you can continue to
operate the liftgate.
Switching the Power Liftgate On
or Off
You can switch the power liftgate on or off
through the vehicle settings on your
touchscreen.
When switched off, the liftgate only
unlatches and will not power open or close.
Hands-Free Feature (If Equipped)
Make sure you have the passive key within
3 ft (1 m)
of the liftgate.
1. Stand behind your vehicle, and face the
liftgate.
2. Move your foot, in a single-kick motion,
without pausing, under and away from
the rear bumper detection area.

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.
