2014 FORD C MAX HYBRID battery

During certain events (such as vehicle
servicing) your low voltage 12-volt battery
may become disconnected or disabled.
Once the battery is reconnected and after
driving the vehicle, the engine may
continue to operate for three to five
seconds after the key is turned to off. This
is a normal condition.
Braking: Your hybrid is equipped with
standard hydraulic braking and
regenerative braking. Regenerative braking
is performed by your transmission and it
captures brake energy and stores it in your
high voltage battery.
Driving to optimize fuel economy
Note: Having your engine running is not
always an indication of inefficiency. In some
cases, it is actually more efficient than
driving in electric mode.
Your fuel economy should improve
throughout your hybrid's break-in period.
As with any vehicle, your driving habits and
accessory usage can significantly impact
your fuel economy. For best results, keep
in mind these tips:
• Keep the tires properly inflated and
only use the recommended size.
• Aggressive driving increases the
amount of energy required to move
your vehicle. In general, you can
achieve better fuel economy with mild
to moderate acceleration and
deceleration. Moderate braking is
particularly important since it allows
you to maximize the energy captured
by the regenerative braking system. Additional Tips:
•
Do not carry extra loads.
• Be mindful of adding external
accessories that may increase
aerodynamic drag.
• Observe posted speed limits.
• Perform all scheduled maintenance.
• There is no need to wait for your engine
to warm up. The vehicle is ready to
drive immediately after starting.
EV+ Mode
Your vehicle will recognize your frequent
destinations and allow for more EV driving
as you approach them. For example, when
nearing your home it should be easier to
stay in electric mode. The EV indicator will
display EV+ when this mode is active. You
should see this approximately 1/8 mile
(200 meters) from a frequent destination.
See
Information Displays (page 88).
Note: Frequent destinations are learned by
your vehicle after two to four weeks of use.
You can clear these destinations with a
Driving History reset through the Settings
menu.
Note: The EV+ feature can be turned on or
off through the Driver Assist section of the
Settings menu.

Frequently asked questions
Answer
Question
The high voltage battery is electrically isol-ated from the rest of the vehicle when the key is off. When you turn the key on, highvoltage 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 thesecontactors 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 keystart will start the engine if it is necessaryfor cabin heating, windshield defrost, or if
the outside temperature is low. (For C-MAX Energi vehicles, the engine may not berequired to operate these functions.)
Why does the engine sometimes start at
key-on?
There are several reasons the engine stayson 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 thisspeed 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 controlsystem 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?

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 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
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
182).
Can I tow the hybrid behind my motor home
with all four wheels down?

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.

CHARGING THE HIGH-VOLTAGE
BATTERY (ENERGI VEHICLES) WARNINGS
Do not use the 120-volt convenience
cord with an extension cord or
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. 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. Using
the standard 120-volt convenience cord
takes approximately 7 hours to completely
charge from an empty battery. Ford recommends upgrading to the
optional 240-volt charging station for
faster more efficient charging. Using a
240-volt charging station will take
approximately 2 ½ hours to fully charge an
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. You must use a
dedicated line, which means you cannot
have other appliances connected to the
same circuit. If you do not use a dedicated
circuit, the circuit breaker could trip or open.
If you do not have a dedicated circuit,
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 charge port receptacle of
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 up when you plug the cord into the
AC wall outlet.
Charge (green light) —
indicates status
of charging:
• No light means you have not connected
the cord to the vehicle.
• Blinking light means that the charging
is in process.
• Solid light means you have connected
the cord, but the vehicle is 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. You need to
unplug the cord and then plug it back
in to reset the fault. If the fault persists,
contact your authorized dealer. Charge Port
The charge port is located between the
front left side door and front left wheel
well. There is an indentation located on
the charge port door. Press in and release
with your thumb to open and close the
door.
Note:
Do not force the charge port door
open or closed. Forcing the door open or
closed will damage the charge port.
The light ring located around the charge
port indicates the charge status of the
high-voltage battery in your vehicle.
Divided into four quadrants, the charge
port light ring displays the state of charge
in 25 percent increments.
There is a cord acknowledgment feature
that activates when you initiate a charge
cycle. The four light quadrants will each
individually flash clockwise starting with
the top right light and ending with the top
left, two full times, confirming the system
detects the charging coupler.
Use your key fob to view the charge status
of your vehicle at any time by pressing the
unlock button. The light ring will light up
the corresponding quadrant(s) so that the
current state of charge can be determined.
