Protecting the environment
We must all play our part in
protecting the environment. Correct
vehicle usage and the authorized
disposal of waste, cleaning and
lubrication materials are significant
steps towards this aim. Information in this respect is highlighted in this
guide with the tree symbol.

PERCHLORATE MATERIAL
Certain components of this vehicle such as airbag modules, seat belt
pretensioners, and button cell batteries may contain Perchlorate Material
– Special handling may apply for service or vehicle end of life disposal.
See www.dtsc.ca.gov/hazardouswaste/perchlorate.
BREAKING-IN YOUR VEHICLE
Your vehicle does not need an extensive break-in. Try not to drive
continuously at the same speed for the first 1,000 miles (1,600 km) of
new vehicle operation. Vary your speed frequently in order to give the
moving parts a chance to break in.
Do not add friction modifier compounds or special break-in oils since
these additives may prevent piston ring seating. SeeEngine oilin the
Maintenance and Specificationschapter for more information on oil
usage.
HYBRID OPERATION
This hybrid vehicle combines electric and gasoline propulsion without
compromise, to provide breakthrough performance and efficiency. It
requires no special fuels and never has to be plugged in. Familiarizing
yourself with these unique characteristics will help ensure optimal
performance from your new vehicle.

Normal vehicle operation
Starting:Turn the ignition key to
the start position while your vehicle
is in P (Park). The green “Ready
Indicator” light will appear in the
instrument cluster, letting you know
that the vehicle is ready for driving. The engine may not start because
this Hybrid vehicle is equipped with Silent Key Start (SKS). 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 the vehicle is on, whether the engine is running or not to indicate
the vehicle is capable of movement (using its electric motor, engine, or
both). The vehicle’s computer will determine if an engine start is
required. Typically, the engine will not start unless the vehicle is cold, a
climate control change is requested, or the accelerator is depressed.
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.
Driving:The gas engine automatically starts and stops to provide power
when it’s needed and to save fuel when it’s not. While coasting at low
speeds, coming to a stop, or standing, the gas engine normally shuts
down and the 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 47 mph (75 km/h)
•Ascending a hill
•Charge level of high voltage battery is low
•Very high or low outside temperature (to provide system
cooling/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 the vehicle is not required. Simply step on the
accelerator when you are ready to drive.
Transmission Operation:Due to the technologically advanced,
electronically-controlled Continuously Variable Transaxle (eCVT) you will
not feel shift changes like those of a non-hybrid vehicle. Your hybrid’s
transmission is designed to do its work seamlessly.
Introduction

Since engine speed is controlled by the transmission, it may seem
elevated at times. This is normal hybrid operation and helps
deliver fuel efficiency and performance.
Neutral:It is not recommended to idle the vehicle in N (Neutral) for
extended periods of time because this will discharge your high voltage
battery and decrease fuel economy. Because of the unique nature of the
hybrid vehicle, the engine will not start in the N (Neutral) position. Also,
the engine cannot provide power to the hybrid system in N (Neutral).
Low Gear:L (Low gear) is designed to mimic the enhanced engine
braking available in non-hybrid vehicles. L (Low gear) will produce high
engine speeds to provide necessary engine braking. This is normal and
will not damage your vehicle. In L (Low gear) the gas engine will remain
on more often than in D (Drive gear).
Reverse:R (Reverse gear) vehicle speed is limited to 22 mph
(35 km/h).
Unique Hybrid operating characteristics
Your Hybrid, with its new technology, behaves differently compared to a
non-hybrid. Here is a description of the major differences:
Battery:Your Hybrid is equipped with a high voltage battery. A cool
battery ensures battery life and provides the best possible performance.
Your hybrid high voltage battery may periodically re-condition itself to
ensure maximum efficiency. You may notice slight changes in drivability
during this process, but it’s an important part of your hybrid’s high
voltage battery optimization features.
The high voltage battery is cooled by cabin air drawn from vent holes in
the front of the rear seat cushions. Avoid placing objects at the vent
holes which block air flow to the high voltage battery.
The high voltage battery is located between the rear passenger seat and
the trunk. Due to this location, the rear seat for the hybrid vehicle does
not have the ability to be lowered to allow pass-through between the
trunk and the rear of the passenger compartment. Do not attempt to
lower the rear seat.
If the vehicle is left inoperative for over 31 days, it may be necessary to
jumpstart the vehicle. For more information, refer toJump starting
(Low voltage [underhood] battery only)in theRoadside Emergencies
chapter and also refer toLow and high voltage battery — storagein
theMaintenance and Specificationschapter.

Engine:The engine speed in your hybrid is not directly tied to your
vehicle speed. Your vehicle’s engine and transmission are designed to
deliver the power you need at the most efficient engine speed. During
heavy accelerations, your hybrid may reach high engine speeds (up to
6000 RPM). This is characteristic of the Atkinson cycle engine
technology helping to maximize your hybrid’s fuel economy.
In prolonged mountainous driving, you may see the engine tachometer
changing without your input. This is intentional and maintains the
battery charge level. You may also notice during extended downhill
driving that your engine continues to run instead of shutting off.
During this “engine braking”, the engine stays on, but it’s 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 generator in the
hybrid system.
During certain events (such as vehicle servicing) your low voltage
(underhood) battery may become disconnected or disabled. When this
occurs, and after reconnecting the low voltage (underhood) battery and
driving the vehicle, the engine may continue to operate for 3-5 seconds
after the key is turned to the off position. This is a normal condition, as
the vehicle’s computers are relearning the operating characteristics of
your particular engine in order to operate it at maximum efficiency.
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
Your fuel economy should improve throughout your hybrid’s break-in
period. As with any vehicle, fuel economy can be significantly impacted
by your driving habits and accessory usage. For best results, keep in
mind these tips:
Tire Inflation:Keep tires properly inflated and only use recommended
size.
Drive Habits:Aggressive driving increases the amount of energy
required to move your vehicle. In general, better fuel economy is
achieved 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.
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.

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

Specificationschapter for more fuel saving tips.
Frequently asked questions
Question Answer
What are the series
of clicks from the
cargo area when I
first turn the key in
the ignition?The high voltage battery is electrically isolated
from the rest of the vehicle when the key is off.
When the key is turned to on, high voltage
contactors inside the battery are closed to make
the electricity available to the motor/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.
Why does the engine
sometimes start at
key-on?The vehicle’s computer will determine if an
engine start is required at key-on. Silent Key
Start (SKS) will start the engine if it is
necessary for cabin heating, windshield defrost,
or if the outside temperature is low.
Why does it take a
long time before the
engine shuts down?There are several reasons the engine stays on for
an extended amount of time when it is first
started. One common reason is to ensure that
the emissions components are warm enough to
minimize tailpipe emissions. As the climate gets
cooler, this “engine-ON” time is extended.
Why does my engine
never shut down
above 47 mph
(75 km/h)?The engine is required to turn on above this
speed to protect the transmission hardware.

Question Answer
Why does my engine
stay ON when it’s
extremely cold
outside?In order to ensure that the climate control
system can begin heating the cabin and/or
defrosting the windshield as soon as a driver
requests it, the engine coolant temperature has
to be kept sufficiently hot. Keeping the engine
on is required to maintain the correct minimum
temperature.
Why does my engine
revupsohigh
sometimes when I
accelerate?Your vehicle’s engine and transmission are
designed to deliver the power you need at the
most efficient engine speed. This may be higher
than expected during heavy accelerations, and
may fluctuate during steady state driving. These
are characteristics of the Atkinson engine cycle
and the eCVT transmission technology that help
maximize your hybrid’s fuel economy.
What is the fan noise
I hear from the rear
of my hybrid?The fan noise comes from a fan located inside
the high voltage battery. This fan turns on when
the battery requires cooling air. The fan speed,
and associated noise level, will change according
to the amount of cooling required to maintain
good performance. Maintaining the battery
temperature at optimal conditions also prolongs
the useful life of the battery and helps to
achieve better fuel economy.
HowfarcanIgoin
Electric Drive if I
run out of gas?Running out of gas is not recommended.
However, you may be able to go about one mile,
driving at 30 mph (48 km/h), if the battery has a
normal state of charge.
What is the engine
oil change service
interval?The engine oil should be changed every
10,000 miles (16,000 km) under normal
operating conditions. See theScheduled
Maintenance Guidechapter.

DATA RECORDING
Service Data Recording
Service data recorders in your vehicle are capable of collecting and
storing diagnostic information about your vehicle. This potentially
includes information about the performance or status of various systems
and modules in the vehicle, such as engine, throttle, steering or brake
systems. In order to properly diagnose and service your vehicle, Ford
Motor Company, Ford of Canada, and service and repair facilities may
access or share among them vehicle diagnostic information received
through a direct connection to your vehicle when diagnosing or servicing
your vehicle. For U.S. only (if equipped), if you choose to use the SYNC
Vehicle Health Report, you consent that certain diagnostic information
may also be accessed electronically by Ford Motor Company and Ford
authorized service facilities, and that the diagnostic information may be
used for any purpose. See yourSYNCsupplement for more information.
Event Data Recording
This vehicle is equipped with an event data recorder (EDR). The
main purpose of an EDR is to record, in certain crash or near
crash-like situations, such as an airbag deployment or hitting a
road obstacle; this data will assist in understanding how a
vehicle’s systems performed. The EDR is designed to record data
related to vehicle dynamics and safety systems for a short period
of time, typically 30 seconds or less. The EDR in this vehicle is
designed to record such data as:
•How various systems in your vehicle were operating;
•Whether or not the driver and passenger seatbelts were
buckled/fastened;
•How far (if at all) the driver was depressing the accelerator
and/or the brake pedal; and
•How fast the vehicle was travelling; and
•Where the driver was positioning the steering wheel.
This data can help provide a better understanding of the
circumstances in which crashes and injuries occur.
Note: EDR data is recorded by your vehicle only if a non-trivial
crash situation occurs; no data is recorded by the EDR under
normal driving conditions and no personal data or information
(e.g., name, gender, age, and crash location) is recorded (see
