Question Answer
Why does my engine
never shut down above
45 mph (73 km/h)?The engine is required to turn on above
this speed to protect the transmission
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 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.

PRESSURE when the engine oil level is low. Check the oil level and add
oil if needed. If the warning light or message stays on, even though the
oil level is correct, do not start the engine and contact your authorized
dealer as soon as possible. This indicates a problem with the engine or a
related component. Refer toEngine oilin theMaintenance and
Specificationschapter.
High engine or high motor
electronic coolant temperature
(RTT):Illuminates when the engine
coolant or motor electronics coolant temperature is high. The message
center displays HIGH ENGINE TEMPERATURE / HIGH MOTOR
TEMPERATURE when the engine coolant or motor electronics are
overheating. Stop the vehicle as soon as safely possible, turn off the
engine, and let it cool. Check the coolant and coolant level. If the light
and message stays on or continues to turn on after the vehicle warms
up, contact your authorized dealer as soon as possible. Continuing to
drive with an overheated engine can cause serious engine damage. This
indicates a problem with the engine or a related component. Refer to
Engine coolant and motor/electronics coolantin theMaintenance
and Specificationschapter.
WARNING:Never remove the coolant reservoir cap while the
engine is running or hot.

temperature, the level indicator will
be blue and will be in the normal
range (between “H” and “C”). If the
engine coolant temperature exceeds
the normal range, the level indicator
will change to red to indicate that
the engine is overheating. Stop the
vehicle as soon as safely possible,
switch off the engine and let the engine cool.

Warning messages that have been reset are divided into two categories:
•They will reappear on the display ten minutes from the reset.
•They will not reappear until an ignition on/off cycle has been
completed if the fault condition still exists. This acts as a reminder
that these warning conditions still exist within the vehicle.
Warnings that return after 10 minutes:
PARK BRAKE ENGAGED— Displayed when the park brake is
engaged. If the warning stays on after the park brake is off, contact your
authorized dealer as soon as possible.
CHECK BRAKE SYSTEM— Displayed when the brake system needs
servicing. If the warning stays on or continues to come on, contact your
authorized dealer as soon as possible.
Warnings that return after the ignition key is turned from off to
on:
STOP SAFELY NOW— Displayed when the stop safety hazard warning
lamp is illuminated. This indicates a hybrid component fault/failure that
will cause the vehicle to shut down, fail to start or enter into limited
operating mode.
Note: If the vehicle is still running, it may soon shut down without
further warning and should be stopped safely. Contact your authorized
dealer as soon as possible.
HIGH ENGINE TEMPERATURE— Displayed when the engine
coolant is overheating. Engine coolant temperature warning lamp will
illuminate indicating coolant temperature is high. Stop the vehicle as
soon as safely possible, turn off the engine and let it cool. Check the
coolant level. Refer toEngine coolantin theMaintenance and
Specificationschapter. If the warning stays on or continues to come on,
contact your authorized dealer as soon as possible.
WARNING:When the engine and radiator are hot, scalding
coolant and steam may shoot out under pressure and cause
serious injury. Do not remove the cooling system cap when the engine
and radiator are hot.
HIGH MOTOR TEMPERATURE— Displayed when the motor
electronics are overheating. Stop the vehicle as soon as safely possible,
turn off the engine and let it cool. Refer toEngine coolant and
motor/electronics coolantin theMaintenance and Specifications
chapter. If the warning stays on or continues to come on, contact your
authorized dealer as soon as possible.

Guarding against exhaust fumes
Carbon monoxide is present in exhaust fumes. Take precautions to avoid
its dangerous effects.
WARNING: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 HEATER (IF EQUIPPED)
An engine block heater warms the engine coolant which aids in starting
and allows the heater/defroster system to respond quickly. If your vehicle
is equipped with this system, your equipment includes a heater element
which is installed in your engine block and a wire harness which allows
the user to connect the system to a grounded 120 volt a/c electrical
source. The block heater system is most effective when outdoor
temperatures reach below 0°F (-18°C).
WARNING:Failure to follow engine block heater instructions
could result in property damage or physical injury.
WARNING:To reduce the risk of electrical shock, do not use
your heater with ungrounded electrical systems or two-pronged
(cheater) adapters.
Prior to using the engine block heater, follow these recommendations for
proper and safe operation:
•For your safety, use an outdoor extension cord that is product
certified by Underwriter’s Laboratory (UL) or Canadian Standards
Association (CSA). Use only an extension cord that can be used
outdoors, in cold temperatures, and is clearly markedSuitable for Use
with Outdoor Appliances.Never use an indoor extension cord
outdoors; it could result in an electric shock or fire hazard.
•Use a 16 gauge outdoor extension cord, minimum.
•Use as short an extension cord as possible.

WINDSHIELD WASHER FLUID
Add fluid to fill the reservoir if the
level is low. In very cold weather, do
not fill the reservoir completely.
Only use a washer fluid that meets
Ford specification WSB-M8B16-A2.
Do not use any special washer fluid
such as windshield water repellent
type fluid or bug wash. They may
cause squeaking, chatter noise, streaking and smearing. Refer to the
Maintenance product specifications and capacitiessection in this
chapter.
State or local regulations on volatile organic compounds may restrict the
use of methanol, a common windshield washer antifreeze additive.
Washer fluids containing non-methanol antifreeze agents should be used
only if they provide cold weather protection without damaging the
vehicle’s paint finish, wiper blades or washer system.
WARNING:If you operate your vehicle in temperatures below
40°F (5°C), use washer fluid with antifreeze protection. Failure
to use washer fluid with antifreeze protection in cold weather could
result in impaired windshield vision and increase the risk of injury or
accident.
Note:Do not put washer fluid in the engine coolant reservoir. Washer
fluid placed in the cooling system may harm engine and cooling system
components.
CHANGING THE WIPER BLADES
1. Pull the wiper arm away from the
vehicle. Turn the blade at an angle
from the wiper arm. Push the lock
tab to release the blade and pull the
wiper blade down toward the
windshield to remove it from the
arm.
2. Attach the new wiper to the
wiper arm and press it into place
until a click is heard.
Replace wiper blades at least once per year for optimum performance.
