GENERAL INFORMATION
WARNING: Extended idling at high
engine speeds can produce very high
temperatures in the engine and exhaust
system, creating the risk of fire or other
damage. WARNING:
Do not park, idle or drive
your vehicle on dry grass or other dry
ground cover. The emission system heats
up the engine compartment and exhaust
system, creating the risk of fire. WARNING:
Do not start the vehicle
in a closed garage or in other enclosed
areas. Exhaust fumes can be toxic. Always
open the garage door before you start the
vehicle. WARNING:
If you smell exhaust
fumes inside your vehicle, have your
vehicle checked by an authorized dealer
immediately. Do not drive your vehicle if
you smell exhaust fumes. If you disconnect the battery, your vehicle
may exhibit some unusual driving
characteristics for approximately 5 mi (8 km)
after you reconnect it. This is because the
engine management system must realign
itself with the engine. You can disregard any
unusual driving characteristics during this
period.
The powertrain control system meets all
Canadian interference-causing equipment
standard requirements regulating the
impulse electrical field or radio noise.
When you start your vehicle, avoid pressing
the accelerator pedal until the ready to drive
indicator illuminates. Only use the
accelerator pedal when you have difficulty
starting your vehicle.
KEYLESS STARTING
Note:
The keyless starting system may not
function if the key is close to metal objects
or electronic devices such as cellular
phones. Note:
A valid key must be located inside
your vehicle to switch the ignition on and
start the vehicle.

The keyless starting system has three
modes:
•
Off: Turns the ignition off.
• Without applying the brake pedal,
press and release the button once
when the ignition is in the on mode,
or when the vehicle is running but is
not moving.
• On:
All electrical circuits are operational
and the warning lamps and indicators
illuminate.
• Without applying the brake pedal,
press and release the button once.
• Start:
Starts the vehicle. The engine may
not start when the vehicle starts.
• Press the brake pedal, and then press
the button until the vehicle starts. An
indicator light on the button
illuminates when the ignition is on
and when the vehicle starts. STARTING A HYBRID ELECTRIC
VEHICLE SYSTEM
When the engine starts for the first time on
your drive, the idle speed increases, this
helps to warm up the engine. If the engine
idle speed does not slow down automatically,
have your vehicle checked by an authorized
dealer.
Note:
You can crank the engine for a total
of 60 seconds without the engine starting
before the starting system temporarily
disables. The 60 seconds does not have to
be all at once. For example, if you crank the
engine three times for 20 seconds each time,
without the engine starting, you reached the
60-second time limit. A message appears
in the information display alerting you that
you exceeded the cranking time. You
cannot attempt to start the engine for at
least 15 minutes.
Note: After 15 minutes, you are limited to a
15-second engine cranking time. You need
to wait 60 minutes before you can crank the
engine for 60 seconds again. Before starting your vehicle, check the
following:
•
Make sure all occupants have fastened
their seatbelts.
• Make sure the headlamps and electrical
accessories are off.
• Make sure the parking brake is on.
• Put the transmission in
P.
Note: Do not touch the accelerator pedal.
1. Fully depress the brake pedal.
2. Press the button.
Note: The green ready indicator illuminates
letting you know that your vehicle is ready
for driving. Since your vehicle is equipped
with a silent key start, the engine may not
start when your vehicle starts.
See Hybrid
Vehicle Operation (page 173).
The system does not function if:
• The key frequencies are jammed.
• The key battery has no charge.
If you are unable to start your vehicle, do the
following:

1. Remove the rubber covering (A) in the
cupholder. With the buttons facing
upward and the unlock button facing the
front of your vehicle, place the first
intelligent access key into the backup
slot (B).
2. With the key in this position, press the brake pedal, then the START button to
switch the ignition on and start your
vehicle. Fast Restart
The fast restart feature allows you to restart
your vehicle within 20 seconds of switching
it off, even if it does not detect a valid
passive key.
Within 20 seconds of switching your vehicle
off, press the brake pedal and press the
button. After 20 seconds, you can no longer
start your vehicle if it does not detect a valid
passive key.
Once your vehicle starts, it remains running
until you press the button, even if your
vehicle does not detect a valid passive key.
If you open and close a door while your
vehicle is running, the system searches for
a valid passive key. You cannot start your
vehicle if the system does not detect a valid
passive key within 20 seconds.
Automatic Shutdown
This feature automatically shuts down your
vehicle if it has been idling for an extended
period. The ignition also turns off in order to
save battery power. Before your vehicle
shuts down, a message appears in the
information display showing a timer counting down from 30 seconds. If you do not
intervene within 30 seconds, your vehicle
shuts down. Another message appears in
the information display to inform you that
your vehicle has shut down in order to save
fuel. Start your vehicle as you normally do.
Automatic Shutdown Override
Note:
You cannot permanently switch off the
automatic shutdown feature. When you
switch it off temporarily, it turns on at the
next ignition cycle.
You can stop the shutdown, or reset the
timer, at any point before the 30-second
countdown has expired by doing any of the
following:

HYBRID VEHICLE OPERATION
This hybrid vehicle combines electric and
gasoline propulsion to provide breakthrough
performance and improved efficiency.
Familiarizing yourself with these unique
characteristics will provide an optimal driving
experience from your new vehicle.
Note:
You may notice higher engine speeds
upon start-up. This temporary condition is
normal and necessary to heat up the cabin
and minimize emissions.
Starting: When you start your vehicle, a
green ready indicator light will
appear in the lower right portion
of the instrument cluster and a ready to drive
message will appear in the middle of the left
cluster screen, letting you know that your
vehicle is ready for driving. The engine may not start because this
vehicle is equipped with silent key start. This
fuel saving feature allows your vehicle to be
ready–to–drive without requiring the gas
engine to be running. This indicator will
remain on while your vehicle is on, whether
the engine is running or not to indicate your
vehicle is capable of movement (using its
electric motor, engine, or both). Typically, the
engine will not start unless the vehicle is
cold, a climate control change is requested,
or the accelerator is pressed.
Driving:
The gas engine automatically starts and
stops to provide power when needed and
to save fuel when not needed. While
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.
• Vehicle speed above 85 mph (137 km/h).
However, the maximum speed for
electric-only operation may be lower
while driving in hot temperatures or on
hilly terrain.
• Ascending a hill.
• Charge level of high voltage battery is
low.
• Very high or low outside temperature (to
provide system cooling or heating).
• Engine not warm enough to provide
passenger requested cabin temperature.
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.

During certain events (such as vehicle
servicing) your low voltage 12-volt battery
may become disconnected or disabled. Once
the battery is reconnected and after driving
the vehicle, the engine may continue to
operate for three to five seconds after the
key is turned to off. This is a normal
condition.
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 your high voltage battery.
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 in
mind these tips:
•
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.
ECOSELECT
EcoSelect is a drive mode for non plug-in
vehicles designed to offer the best possible
fuel economy with tradeoffs in vehicle
performance and comfort. To switch EcoSelect on, press the
ECO button.
A graphic displays on your information
display when EcoSelect is on.
Your vehicle will remember the last selected
mode whenever you start your vehicle.
EcoSelect allows your vehicle to operate
more efficiently. You will notice:
• Less aggressive cooling.
• Softer acceleration.
• Increased deceleration when coasting.

HYBRID VEHICLE FREQUENTLY ASKED QUESTIONS Answer
Question
The high voltage battery is electrically isolated 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 avail-
able 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 will determine if an engine start is requiredat key-on. Silent key start will start 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 stays on for an extended amountof 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?
The engine is required to turn on above this speed to protect thetransmission hardware.
Why does my engine never shut down above 85 mph (137 km/h)

Note:
If you do not add new fuel during an
18-month period, fuel freshness mode will
use fuel until approximately 1.2 gal (4.5 L) of
fuel remains in the fuel tank.
During fuel freshness mode:
• The information display will indicate fuel
freshness mode is active.
• EV Now mode will not be available.
• Most of the electric-only driving range
will be saved until fuel freshness mode
is completed.
Note: EV Now mode will become available
when less than 1.2 gal (4.5 L) of fuel remains
in the fuel tank.
Note: When the fuel level is less than
one-quarter full, refueling your vehicle will
end fuel freshness mode.
Note: We recommend you use a fuel
stabilizer if you use less than a full tank of
fuel during an 18-month period.
FUEL FILLER FUNNEL LOCATION
The fuel filler funnel is under the luggage
compartment floor covering. RUNNING OUT OF FUEL
Avoid running out of fuel because this
situation may have an adverse effect on
vehicle components.If you have run out of fuel:
•
To start the vehicle with a keyless
ignition, just start the engine. Crank time
will be longer than usual.
• Normally, adding 1 gal (3.8 L) of fuel is
enough to restart the vehicle. If the
vehicle is out of fuel and on a steep
grade, more than
1 gal (3.8 L) may be
required.
• The service engine soon indicator may
come on.
Refilling With a Portable Fuel Container WARNING:
Flow of fuel through a
fuel pump nozzle can produce static
electricity. This can cause a fire if you are
filling an ungrounded fuel container. WARNING:
Do not insert the nozzle
of a fuel container or an aftermarket funnel
into the fuel filler neck. This may damage
the fuel system filler neck or its seal and
cause fuel to run onto the ground.

If the service engine soon indicator remains
on, have your vehicle serviced at the first
available opportunity. Although some
malfunctions detected by the OBD-II may not
have symptoms that are apparent, continued
driving with the service engine soon indicator
on can result in increased emissions, lower
fuel economy, reduced engine and
transmission smoothness and lead to more
costly repairs.
Readiness for Inspection and
Maintenance (I/M) Testing
Some state and provincial and local
governments may have
Inspection/Maintenance (I/M) programs to
inspect the emission control equipment on
your vehicle. Failure to pass this inspection
could prevent you from getting a vehicle
registration.
If the service engine soon indicator
is on or the bulb does not work,
your vehicle may need service.
See On-Board Diagnostics. 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.

2. Locate the access door and remove the
plastic cover. 3. Pull the outer cover off to expose the
service disconnect cover. 4. Slide the handle on the service
disconnect outboard to the right. 5. Pull the handle toward you and remove
the circuit from the vehicle to disable the
high-voltage battery.
Reactivating the High-Voltage Battery
Note: If you have manually disconnected
your high-voltage shut off circuit you will
need to reconnect the circuit before it can
be reactivated. The vehicle detects if the
electrical system is safe and then
reactivates. HIGH VOLTAGE SHUTOFF SWITCH
The integrity of the high voltage system is
continuously monitored. After a substantial
collision or physical jolt, the high voltage
system could become deactivated. To
reinitialize the system.
1. Press the START/STOP button to turn
the ignition off.
2. Press the brake pedal and press the START/STOP
button.
3. If your vehicle is not powered on after this sequence, repeat steps 1 and 2 up
to two more times.
Note: During this process, your vehicle will
detect if the electrical system is safe and
reactivate. Once your vehicle determines
the electrical system safe, you can start your
vehicle as you would normally by either
turning the ignition key or by pressing the
brake in combination with the START/STOP
button.
Note: In the event your vehicle does not
reactivate after the third key cycle, contact
an authorized dealer.
