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 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.
What is the fan noise and slight
tapping sound I hear from the rear
of my hybrid?The fan noise comes from two fans
located inside the high voltage
battery. These fans turn 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.

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.

Note:After starting the vehicle, the engine may stop running to
conserve fuel after it is warmed-up and the high voltage battery is
sufficiently charged.
Note:If the vehicle does not start, put the gearshift lever into P (Park),
turn the ignition off, then attempt to start the vehicle again. If the
vehicle still does not start, it may require refueling, jump starting,
resetting of the fuel pump/high voltage shut-off switches or service. For
information on jump starting the vehicle and resetting the fuel
pump/high voltage shut-off switches, refer to theJump starting your
vehiclesection and theFuel pump/High voltage shut-off switches
section found in theRoadside Emergencieschapter.
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/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 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 harm.

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 specifications. 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 theMaintenance product specifications and capacities
section 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.
Checking and adding washer fluid for the liftgate
Washer fluid for the liftgate is supplied by the same reservoir as the
windshield.

6. Drive the vehicle to complete the relearning process.
•The vehicle may need to be driven 10 miles (16 km) or more to
relearn the idle and fuel trim strategy.
•If you do not allow the engine to relearn its idle trim, the idle
quality of your vehicle may be adversely affected until the idle
trim is eventually relearned.
If the battery has been disconnected or a new battery has been installed,
the clock and the preset radio stations must be reset once the battery is
reconnected.
•Always dispose of automotive
batteries in a responsible manner.
Follow your local authorized
standards for disposal. Call your
local authorized recycling center
to find out more about recycling
automotive batteries.
Low and high voltage battery – storage
Your vehicle must be started and run for a minimum of 10 minutes once
a month in order to maintain the high voltage battery charge. This will
maintain the high voltage battery but it is not enough to maintain the
low voltage (underhood) battery and additional low voltage (underhood)
battery charging may be required after 60 days.
If your vehicle is to be stored for 30 days or longer, the low voltage
(underhood) battery negative terminal must be disconnected. Failure to
do this could damage your vehicle’s batteries.
ENGINE COOLANT AND MOTOR/ELECTRONICS COOLANT
Your vehicle is equipped with two separate coolant systems. One is for
engine cooling and the other is for various electric motors and other
components that are specific to the hybrid operating systems.
