HYBRID OPERATION
The Hybrid is a whole new kind of SUV that 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 Park (P). The gas engine will turn on,accompanied by the green
“ready indicator” light. Your engine may shut off shortly after starting,
depending on temperature and battery charge level. This is a natural
part of your Hybrid’s fuel-saving features. The “ready indicator” light will
stay on, and you do not need to restart the vehicle.
Note:You may notice higher engine speeds upon start-up. This
temporary condition is normal and necessary to heat up the cabin for
occupant comfort.
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
cause the engine to start up or remain running include:
•Driving request for moderate to rapid acceleration
•Vehicle speed above 40 mph (65 kph)
•Ascending a hill
•ECON mode not selected (while Climate Control is ON)
•Selection of climate control defrost mode or defrost/floor mode
•Charge level of high voltage battery is low
•Very high or low outside temperature (to provide system
cooling/heating)
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.
Since your 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.

Frequently asked questions
Question Answer
What is the pumping sound I hear
when I unlock or enter the vehicle,
and the venting sound a few
minutes after shutting off my
vehicle?This is the hydraulic portion of
your regenerative braking system
pressurizing and depressurizing.
You may also hear it occasionally
after pressing the brake pedal.
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 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 always start
at key-on?Your engine is started at key-on
because the emission components
need to be warm in order to
minimize tailpipe emissions, and in
cooler climates for cabin heating
and windshield defrost
performance.
After I start my car in the
morning, 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.

Question Answer
Why does my engine never shut
down above 40 mph (64 km/h)?The engine is required to turn on
above this speed to protect the
transaxle hardware.
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 rev up so
high 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 transaxle technology
that help maximize your hybrid’s
fuel economy.
What does it mean when my
power assist gauge moves to the
right? To the left?Electricity is coming out of the
battery when the gauge moves to
the right. Electricity is going into
the battery when the gauge moves
to the left.

The auxiliary power point is located
in the instrument panel.
A second auxiliary power point is
located on the rear side of the
center console.
Do not use the power point for
operating the cigarette lighter
element (if equipped).
To prevent the fuse from being
blown, do not use the power
point(s) over the vehicle capacity of 12 VDC/180W. If the power point or
cigar lighter socket is not working, a fuse may have blown. Refer to
Fuses and Relaysin theRoadside Emergencieschapter for information
on checking and replacing fuses.
To prevent the battery from being discharged, do not use the power
point longer than necessary when the engine is not running.
Always keep the power point caps closed when not being used.
Cigar/Cigarette lighter (if equipped)
Do not plug optional electrical accessories into the cigarette lighter
socket.
Do not hold the lighter in with your hand while it is heating, this will
damage the lighter element and socket. The lighter will be released from
its heating position when it is ready to be used.
Improper use of the lighter can cause damage not covered by your
warranty.
Power point (110 VAC) (if equipped)
The 110 VAC power point outlet is used for powering electrical devices
that require up to 150W. Exceeding the 150W limit will cause the power
point to cut off the power temporarily to provide overload protection.

Note:The 110 VAC power point is
equipped with a safety cap and a
safety twist tab. They both provide
protection from inserting any object
into the power point other than the
110 VAC electrical device plug. The
safety cap should always be in a
closed position whenever the power
point outlet is not in use.
The 110 VAC power point is located
in the floor console in front of the
gearshift.
The power outlet is not designed for the following electric appliances;
they may not work properly:
•Cathode ray tube type televisions.
•Motor loads, such as vacuum cleaners, electric saws and other electric
power tools, compressor-driven refrigerators, etc.
•Measuring devices, which process precise data, such as medical
equipment, measuring equipment, etc.
•Other appliances requiring an extremely stable power supply:
microcomputer-controlled electric blankets, touch sensor lamps, etc.
Do not keep electrical devices plugged in the power point
whenever the device is not in use. It is not recommended to use
any extension cord with the 110 VAC power point, since it will
defeat the safety protection design provided by the cap and twist
tab. It will also cause the power point to overload due to
powering multiple devices that can reach beyond the 150W load
limit.
The power point can switch to a fault mode when it is overloaded,
overheated, or shorted. For overloading and shorting conditions, unplug
your device and turn the ignition key off then on. For an overheating
condition, let the system cool off, then turn the ignition key off then on.
The 110 VAC power point can provide power whenever the vehicle
ignition is in the run position and the power point green indicator light
located in the top left corner is turned on. Refer to the indicator light
code below for the power point status.

Guarding against exhaust fumes
Carbon monoxide is present in exhaust fumes. Take precautions to avoid
its dangerous effects.
If you smell exhaust fumes inside your vehicle, have your dealer
inspect your vehicle immediately. Do not drive if you smell
exhaust fumes.
Important ventilating information
If the engine is idling while the vehicle is stopped for a long period of
time, open the windows at least one inch (2.5 cm) or adjust the heating
or air conditioning to bring in fresh air.
ENGINE BLOCK/HIGH VOLTAGE BATTERY HEATER
(IF EQUIPPED)
An engine block/high voltage battery heater warms the engine coolant
and high voltage battery cells which aids in starting, vehicle performance
and heater/defroster performance in cold weather. Use of an engine
block/high voltage battery heater is strongly recommended if you live in
a region where temperatures reach -10°F (-23°C) or below. For best
results, plug the heater in at least three hours before starting the vehicle.
The heater can be plugged in the night before starting the vehicle.
To reduce the risk of electrical shock, do not use your heater
with ungrounded electrical systems or two-pronged (cheater)
adapters.
BRAKES
Occasional brake noise is normal. If a metal-to-metal, continuous grinding
or continuous squeal sound is present, the brake linings may be worn-out
and should be inspected by an authorized dealer. If the vehicle has
continuous vibration or shudder in the steering wheel while braking, the
vehicle should be inspected by an authorized dealer.

Pull the release lever to release the
brake. Driving with the parking
brake on will cause the brakes to
wear out quickly and reduce fuel
economy.
STEERING
Your vehicle is equipped with an Electric Power-Assisted Steering
(EPAS) system. There is no fluid reservoir to check or fill.
If your vehicle loses electrical power while you are driving (or if the
ignition is turned off), you can steer the vehicle manually, but it takes
more effort. Under extreme usage conditions, the steering effort may
increase. This occurs to prevent overheating and permanent damage to
your steering system. If this should occur, you will neither lose the ability
to steer the vehicle manually nor will it cause permanent damage.
Typical steering and driving maneuvers will allow the system to cool and
steering assist will return to normal.
If the steering wanders or pulls, check for:
•an improperly inflated tire
•uneven tire wear
•loose or worn suspension components
•loose or worn steering components
•improper steering alignment
A high crown in the road or high crosswinds may also make the steering
seem to wander/pull.

If the engine coolant has not been checked at the recommended interval,
the engine coolant reservoir may become low or empty. If the reservoir is
low or empty, add engine coolant to the reservoir. Refer toAdding
engine coolantin this chapter.
Note:Automotive fluids are not interchangeable; do not use engine
coolant, antifreeze or windshield washer fluid outside of its specified
function and vehicle location.
Adding engine coolant
When adding coolant, make sure it is a 50/50 mixture of engine coolant
and distilled water. Add the mixture to the coolant reservoir,when the
engine is cool,until the appropriate fill level is obtained.
Do not add engine coolant when the engine is hot. Steam and
scalding liquids released from a hot cooling system can burn you
badly. Also, you can be burned if you spill coolant on hot engine parts.
Do not put engine coolant in the windshield washer fluid
container. If sprayed on the windshield, engine coolant could
make it difficult to see through the windshield.
•Add Motorcraft Premium Gold Engine Coolant or equivalent
meeting Ford specification WSS-M97B51-A1.Refer to
Maintenance product specifications and capacitiesin this chapter.
Note:Use of Motorcraft Cooling System Stop Leak Pellets or an
equivalent product meeting Ford specification WSS-M99B37-B6, may
darken the color of Motorcraft Premium Gold Engine Coolant from
yellow to golden tan.
•Do not add/mix an orange-colored, extended life coolant such
as Motorcraft Specialty Orange Engine Coolant, meeting Ford
specification WSS-M97B44-D, or DEX-COOLbrand with the
factory-filled coolant.Mixing Motorcraft Specialty Orange Engine
Coolant or any orange-colored extended life product such as
DEX-COOLbrand with your factory filled coolant can result in
degraded corrosion protection.
•A large amount of water without engine coolant may be added, in case
of emergency, to reach a vehicle service location. In this instance, the
cooling system must be drained and refilled with a 50/50 mixture of
engine coolant and distilled water as soon as possible. Water alone
(without engine coolant) can cause engine damage from corrosion,
overheating or freezing.

•Do not use alcohol, methanol, brine or any engine coolants
mixed with alcohol or methanol antifreeze (coolant).Alcohol
and other liquids can cause engine damage from overheating or
freezing.
•Do not add extra inhibitors or additives to the coolant.These
can be harmful and compromise the corrosion protection of the engine
coolant.
For vehicles with overflow coolant systems with a non-pressurized cap
on the coolant recovery system, add coolant to the coolant recovery
reservoir when the engine is cool. Add the proper mixture of coolant and
water to the “FULL COLD” level. For all other vehicles which have a
coolant degas system with a pressurized cap, or if it is necessary to
remove the coolant pressure relief cap on the radiator of a vehicle with
an overflow system, follow these steps to add engine coolant.
To reduce the risk of personal injury, make sure the engine is
cool before unscrewing the coolant pressure relief cap. The
cooling system is under pressure; steam and hot liquid can come out
forcefully when the cap is loosened slightly.
1. Before you begin, turn the engine off and let it cool.
2. When the engine is cool, wrap a thick cloth around the coolant
pressure relief cap on the coolant reservoir (a translucent plastic bottle).
Slowly turn cap counterclockwise (left) until pressure begins to release.
3. Step back while the pressure releases.
4. When you are sure that all the pressure has been released, use the
cloth to turn it counterclockwise and remove the cap.
5. Fill the coolant reservoir slowly with the proper coolant mixture (see
above), to within the “COLD FILL RANGE” or the “FULL COLD” level on
the reservoir. If you removed the radiator cap in an overflow system, fill
the radiator until the coolant is visible and radiator is almost full.
6. Replace the cap. Turn until tightly installed. Cap must be tightly
installed to prevent coolant loss.
After any coolant has been added, check the coolant concentration (refer
toChecking engine coolant). If the concentration is not 50/50
(protection to –34°F/–36°C), drain some coolant and adjust the
concentration. It may take several drains and additions to obtain a 50/50
coolant concentration.
