Checking engine coolant
The concentration and level of
engine coolant should be checked at
the intervals listed inscheduled
maintenance information. The
coolant concentration should be
maintained at 50/50 coolant and
distilled water, which equates to a
freeze point of -34°F (-37°C).
Coolant concentration testing is
possible with a hydrometer or
antifreeze tester. The level of
coolant should be maintained at the
FULL COLD level or within the
COLD FILL RANGE in the coolant
reservoir. If the level falls below, add
coolant per the instructions in theAdding engine coolantsection. When
the engine is cold, check the level of engine coolant in the reservoir.
Checking motor/electronics (M/E) coolant
The M/E coolant reservoir is located
at the rear of the engine
compartment. Refer to the following
engine coolant sections for all
information, instructions and
warnings related to cooling systems.
The two systems use the same
coolant and operate similarly, with
the Motor and Electronics system
generally operating at a lower
temperature and pressure. The fluid
levels in both reservoirs need to be maintained. When the engine is cold,
check the level of M/E coolant in the reservoir. The coolant should be at
the FULL COLD level as shown on the side of the coolant reservoir.
Factory fill and coolant specifications
Your vehicle was factory-filled with a 50/50 engine coolant and water
concentration. If the concentration of coolant falls below 40% or above
60%, the engine parts could become damaged or not work properly.A
50/50 mixture of coolant and water provides the following:
•Freeze protection down to -34°F (-37°C).
•Boiling protection up to 265°F (129°C).

•Protection against rust and other forms of corrosion.
•Enables calibrated gauges to work properly.
Common instructions for cooling systems
•The engine coolant should be at the FULL COLD level or within the
COLD FILL RANGE as listed on the engine coolant reservoir
(depending upon application).
•Refer to thescheduled maintenance informationfor service interval
schedules.
•Be sure to read and understandPrecautions when servicing your
vehiclein this chapter.
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. If coolant is
filled to the COLD FILL RANGE or FULL COLD level when the engine is
not cool, the system will remain underfilled.
WARNING: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.
WARNING: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.

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, 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/–37°C), drain some coolant and adjust the
concentration. It may take several drains and additions to obtain a 50/50
coolant concentration.
Whenever coolant has been added, the coolant level in the coolant
reservoir should be checked the next few times you drive the vehicle. If
necessary, add enough 50/50 concentration of engine coolant and
distilled water to bring the liquid level to the proper level.
If you have to add more than 1.0 quart (1.0 liter) of engine coolant per
month, have your authorized dealer check the engine cooling system.
Your cooling system may have a leak. Operating an engine with a low
level of coolant can result in engine overheating and possible engine
damage.
Recycled engine coolant
Ford Motor Company does NOT recommend the use of recycled engine
coolant since a Ford-approved recycling process is not yet available.
Used engine coolant should be disposed of in an appropriate
manner. Follow your community’s regulations and standards for recycling
and disposing of automotive fluids.
Coolant refill capacity
To find out how much fluid your vehicle’s cooling system can hold, refer
toMaintenance product specifications and capacitiesin this chapter.
Fill your engine coolant reservoir as outlined inAdding engine coolant

•Keep the fuel pump nozzle in contact with the fuel container while
filling.
•DO NOT use a device that would hold the fuel pump handle in the fill
position.
Easy Fuel™ “no cap” fuel system
Your fuel tank is equipped with an Easy Fuel™ “no cap” fuel filler
system. This allows you to simply open the fuel filler door and insert the
fuel filler nozzle into the fuel system. The Easy Fuel™ system is
self-sealing and protected against dust, dirt, water and snow/ice.
When fueling your vehicle:
1. Turn the engine off.
2. Open the fuel filler door.
3. Slowly insert the fuel filler nozzle fully into the fuel system, and leave
the nozzle fully inserted until you are done pumping. Pump fuel as
normal.
4. After you are done pumping fuel, slowly remove the fuel filler
nozzle—allow about five seconds after pumping fuel before removing the
fuel filler nozzle. This allows residual fuel to drain back into the fuel tank
and not spill onto the vehicle.
Note:A fuel spillage concern may occur if overfilling the fuel tank. Do
not overfill the tank to the point that the fuel is able to bypass the fuel
filler nozzle. The overfilled fuel may run down the drain located below
and in front of the fuel filler door.
If the check fuel fill inlet lamp or CHECK FUEL FILL INLET message
comes on, the fuel fill inlet may not have properly closed. The inlet may
have stuck open or debris may be preventing the inlet from fully closing.
At the next opportunity, safely pull off the road, turn off the engine,
open the fuel filler door and remove any visible debris from the fuel fill
opening. Insert either the fuel fill nozzle or the fuel fill funnel (see
Refilling with a portable fuel containerfor funnel location) provided
with the vehicle several times to dislodge any debris and/or allow the
inlet to close properly. If this action corrects the problem, the check fuel
fill inlet lamp or CHECK FUEL FILL INLET message may not reset
immediately. It may take several driving cycles for the check fuel fill inlet
lamp or CHECK FUEL FILL INLET message to turn off. A driving cycle
consists of an engine start-up (after four or more hours with the engine
off) followed by city/highway driving. Continuing to drive with the check
fuel fill inlet lamp or CHECK FUEL FILL INLET message on may cause
the service engine soon lamp to turn on as well.

Driving style — good driving and fuel economy habits
Since it is able to operate in electric mode and to collect braking energy,
your hybrid vehicle may get better fuel economy in city driving than on
the highway. This is contrary to conventional vehicles. However, many of
the same actions that improve fuel economy in a conventional vehicle
will also improve fuel economy in this vehicle.
Give consideration to the lists that follow and you may be able to
improve your fuel economy.
Habits
•Avoid aggressive driving. Quick acceleration and deceleration decrease
fuel economy.
•Drive at a smooth, constant speed. Excessive variation in pedal input
causes more operating mode changes and reduces efficiency.
•Drive at reasonable speeds. Traveling at 60 mph [96 km/h] uses
approximately 20% less fuel than traveling at 70 mph [112 km/h]).
•Minimize A/C and defroster usage. Your vehicle is equipped with an
electric A/C system, which can provide cooling for passenger comfort
or defrost without running the engine. However, the A/C system uses
battery energy when the engine is off, which reduces fuel economy.
Using Auto mode, minimizing use of defrost and Max A/C, or choosing
a higher temperature setting can help reduce energy usage.
•Minimize temperature extremes when the vehicle is parked, for
example by storing in a garage to avoid extreme cold in winter and
extreme sun loads in summer. The high voltage battery operates more
efficiently in moderate temperatures, and less energy will be spent
returning the passenger compartment to a comfortable temperature.
•Combine errands. Your vehicle is more fuel efficient when the engine
is warm. Driving to your farthest destination first will warm the engine
more quickly and may improve fuel economy for the rest of the trip.
Maintenance
•Keep tires properly inflated and use only recommended size.
•Keep wheels properly aligned.
•Use recommended engine oil. Refer toMaintenance product
specifications and capacitiesin this chapter.
•Perform all regularly scheduled maintenance items. Follow the
recommended maintenance schedule and owner maintenance checks
found inscheduled maintenance information.

electrical system dry out. After three driving cycles without these or any
other temporary malfunctions present, the service engine soon
indicator should stay off the next time the engine is started. A driving
cycle consists of a cold engine startup followed by mixed city/highway
driving. No additional vehicle service is required.
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/Maintenance (I/M) testing
Some state/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. 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 considered not ready for I/M testing.
If the service engine soon
indicator is on or the bulb does not
work, the vehicle may need to be serviced. Refer toOn-board
diagnostics (OBD-II)in this chapter.
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 the vehicle is ready for I/M testing.
The OBD-II system is designed to check the emission control system
during normal driving. A complete check may take several days. If the
vehicle is not ready for I/M testing, the following driving cycle consisting
of mixed city and highway driving may be performed:
15 minutes of steady driving on an expressway/highway followed by
20 minutes of stop-and-go driving with at least four 30-second idle
periods.

Allow the vehicle to sit for at least eight hours without starting the
engine. Then, start the engine and complete the above driving cycle. The
engine must warm up to its normal operating temperature. Once started,
do not turn off the engine until the above driving cycle is complete. If
the vehicle is still not ready for I/M testing, the above driving cycle will
have to be repeated.
BRAKE FLUID
The fluid level will drop slowly as
the brakes wear, and will rise when
the brake components are replaced.
Check fluid levels with the ignition
in the on position. Fluid levels
between the MIN and MAX lines are
within the normal operating range;
there is no need to add fluid.
If the fluid levels are outside of the
normal operating range the performance of your brake system could be
compromised; seek service from your authorized dealer immediately.
TRANSMISSION FLUID
Checking electronically-controlled Continuously Variable
Transmission (eCVT)
The eCVT does not have an underhood transmission fluid dipstick.
Your transmission does not consume fluid. It is designed to be filled for
life. However, the fluid level should be checked if the transmission is not
working properly, or if you notice some sign of fluid leakage.
Transmission fluid should be checked and, if required, fluid
should be added by an authorized dealer.
Do not use supplemental transmission fluid additives, treatments or
cleaning agents. The use of these materials may affect transmission
operation and result in damage to internal transmission components.
AIR FILTER
Your vehicle is equipped with a long life air filter. The air filter is
designed to last the life of the vehicle. See your authorized dealer or a
qualified technician for replacement. The technician can check the
diagnostics system for the possibility of an excessively dirty air filter.

Removing vehicle from storage
When your vehicle is ready to come out of storage, do the following:
•Wash your vehicle to remove any dirt or grease film build-up on
window surfaces.
•Check windshield wipers for any deterioration.
•Check under the hood for any foreign material that may have collected
during storage (mice/squirrel nests).
•Check the exhaust for any foreign material that may have collected
during storage.
•Check tire pressures and set tire inflation per the Tire Label.
•Check brake pedal operation. Drive the vehicle 15 ft (4.5 meters) back
and forth to remove rust build up.
•Check fluid levels (including coolant, oil and gas) to make sure there
are no leaks, and fluids are at recommended levels.
•If the battery was removed, clean the battery cable ends and inspect.
If you have any concerns or issues, contact your authorized dealer.
