2015 FORD C MAX HYBRID battery

Answer
Question
Your vehicle's engine and transmission aredesigned to deliver the power you need atthe most efficient engine speed. This may be higher than expected during heavy
accelerations, and may fluctuate when
driving at a steady speed. These are charac- teristics of the Atkinson engine cycle and the transmission technology that helpmaximize 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
next to the high voltage battery pack. This fan turns on when the battery requires
cooling air. The fan speed, and associated noise level, will change according to theamount 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 kilometers) 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 designedto 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 C-MAX 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
181).
Can I tow the hybrid behind my motor home
with all four wheels down?

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 and
Maintenance (I/M) Testing
Some state and 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.
If the service engine soon
indicator is on or the bulb does
not work, your vehicle may need
service. See On-Board Diagnostics.
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 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 your vehicle is ready
for I/M testing. The OBD-II system checks the emission
control system during normal driving. A
complete check may take several days. If
the vehicle is not ready for I/M testing, you
can perform the following driving cycle
consisting of mixed city and highway
driving:
15 minutes of steady driving on an
expressway or highway followed by 20
minutes of stop-and-go driving with at
least four 30-second idle periods.
Allow your 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, you
need to repeat the above driving cycle.

CHARGING THE HIGH
VOLTAGE BATTERY WARNINGS
Do not use the 120 volt convenience
cord with an extension cord,
two-prong adaptor, surge protector,
timer or other adapter. In Canada, do not use the 120 volt
convenience cord in commercial
garages.
This equipment has arcing or
sparking parts, do not expose to
flammable vapors. Position this
equipment at least 18 inches (80
millimeters) above the floor. The AC wall plug must fit firmly into
the AC outlet. If the connection feels
loose, worn or the AC outlet is
damaged, please have a qualified
electrician replace the AC outlet. Using a
convenience cord with a worn outlet may
cause burns, property damage and
increase the risk of electric shock. Charging Equipment
Your vehicle is equipped with a standard
120 volt convenience cord located in the
floor compartment behind the driver seat.
Note:
The 120 volt convenience cord allows
you to charge the high voltage battery using
a standard 120 volt household outlet. It
takes approximately seven hours to
completely charge an empty battery using
the standard 120 volt convenience cord.
We recommend upgrading to the optional
240 volt charging station for faster more
efficient charging. It takes approximately
2.5 hours to completely charge an empty
battery using a 240 volt charging station.
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.
• You must use a dedicated line, which
means you cannot have other
appliances connected to the same
circuit.
Note: If you do not have a dedicated circuit,
contact a licensed professional electrician
for proper installation.

C-MAX (CCG) Mexico/United States of America/Canada, enUSA, CPE Review High Voltage BatteryE78097

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 charge port on your
vehicle. 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 when you plug the
cord into the AC wall outlet.
Charge (green light):
• This indicates the status of charging.
• No light means you have not connected
the cord to the vehicle.
• A flashing light means that the
charging is in process.
• A solid light means you have connected
the cord, but your vehicle is not
charging.
Fault (red triangle light):
• This indicates a detected failure and
that charging is not possible.
• A flashing red triangle light means that
the 120 volt convenience cord is trying
to reset the failure and could restart
the charging cycle.
• A solid red triangle light means that the
fault is permanent. You need to unplug
the cord and then plug it back in to
reset the fault. Contact an authorized
dealer.
