2014 FORD FUSION HYBRID battery

Frequently asked questions AnswerQuestion
The high voltage battery is electrically isol-
ated from the rest of the vehicle when the
key is off. When you turn the key 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.What are the series of clicks from the cargo
area when I first turn the key in the ignition?
The vehicle's computer will determine if an
engine start is required at key-on. Silent key
start will start the engine if it is necessary
for cabin heating, windshield defrost, or if
the outside temperature is low. (For Fusion
Energi vehicles, the engine may not be
required to operate these functions.)Why does the engine sometimes start at
key-on?
There are several reasons the engine stays
on for an extended amount of time when
you first start it. One common reason is to
ensure that the emissions components are
warm enough to minimize tailpipe emis-
sions. As the climate gets cooler, this
engine-on time is extended.Why does it take a long time before the
engine shuts down?
The engine is required to turn on above this
speed to protect the transmission hard-
ware.Why does my engine never shut down
above 85 mph (137 km/h)
In order to ensure that the climate control
system can begin heating the cabin 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 main-
tain the correct coolant temperature.Why does my engine stay on when it is
extremely cold outside?
146Unique Driving Characteristics

AnswerQuestion
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 character-
istics of the Atkinson engine cycle and the
transmission technology that help
maximize your hybrid's fuel economy.Why does my engine rev up so high some-
times when I accelerate?
The fan noise comes from a fan located
outside 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.What is the fan noise I hear from the rear
of my hybrid?
Change the engine oil every 10000 miles
(16000 km) or once per year under normal
operating conditions.What is the engine oil change service
interval?
Your hybrid vehicle can use E15 (15%
ethanol, 85% gasoline) fuel, but you may
notice slightly reduced fuel economy
because ethanol contains less energy per
gallon than gasoline. Your hybrid vehicle is
not designed to use E85 (85% ethanol).Can I put E15 or E85 in my vehicle, and how
will it affect my fuel economy?
The high voltage battery system is designed
to last the life of the vehicle and requires
no maintenance.How long will my high voltage battery last?
Does it need maintenance?
There are no provisions for charging the
high voltage battery from a power supply
external to the vehicle. (For Fusion Energi
vehicles, the vehicle can be plugged into a
110-volt outlet with charge cord provided.)Can you charge the battery with a plug into
an A/C outlet?
Yes. Your hybrid vehicle can be flat towed
without modification. See Towing (page
213).Can I tow the hybrid behind my motor home
with all four wheels down?
147Unique Driving Characteristics

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 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 with the ignition Off. Then, start the
vehicle and complete the above driving
cycle. The vehicle must warm up to its
normal operating temperature. Once
started, do not turn off the vehicle 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.

Ford recommends upgrading to the
optional 240-volt charging station for
faster more efficient charging. Use of a
240-volt charging station will take
approximately 2½ hours to fully charge a
empty battery.
Note: Your electrical source must meet
certain requirements for the high-voltage
batteries to charge. The AC outlet must be
a three-prong 110-120 volt AC outlet that is
properly grounded, 15–20 amps (or greater),
and in good condition. The line also must
be dedicated, which means that no other
appliances should be connected to the
same circuit. If a dedicated circuit is not
used, the circuit breaker could trip or open.
If a dedicated circuit is not available, contact
a licensed professional electrician for proper
installation.
Make sure that the 120–volt convenience
cord is completely unwound before
charging. Always plug the cord into the AC
outlet before connecting the charging
coupler into the vehicle’s charge port
receptacle. The 120–volt convenience cord
inline control box has three indicator lights
that represent the charging status; power,
charge and fault.
Power (green light)— this indicator lights
up when the cord is plugged into the AC
wall outlet.
Charge (green light)— indicates status
of charging: • No light means the cord is not
connected to the vehicle.
• Blinking light means that the charging
is in process.
• Solid light means that the vehicle is
connected but not charging.
Fault (red triangle light)— Lights up in
case of a detected failure. No charging is
possible:
• Blinking red triangle light – means that
the 120–volt convenience cord is trying
to reset the failure and could restart
the charging cycle.
• Solid red triangle light – means that
the fault is permanent. The cord needs
to be unplugged and re-plugged to
reset the fault. If the fault persists,
contact your authorized dealer.
