2014 FORD C MAX HYBRID Engine

•
Very high or low outside temperature
(to provide system cooling or heating)
For C-MAX Energi vehicles, climate
control demands by passengers may
not directly cause the engine to run.
This only occurs when the high voltage
battery charge is low, or if the outside
temperature is cold enough to require
the engine to provide additional heat
for the cabin.
• Engine not warm enough to provide
passenger requested cabin
temperature.
Stopping: The gas engine may shut off
to conserve fuel as you come to a stop.
Restarting the vehicle is not required.
Simply step on the accelerator when you
are ready to drive.
Transmission Operation:
Due to the
technologically advanced,
electronically-controlled continuously
variable transaxle, you will not feel shift
changes like those of a non-hybrid vehicle.
Note: Since engine speed is controlled by
the transmission, it may seem elevated at
times. This is normal hybrid operation and
helps deliver fuel efficiency and
performance.
Neutral:
It is not recommended to idle the
vehicle in position N for an extended period
of time because this will discharge your
high voltage battery and decrease fuel
economy. The engine will not start or stop,
and cannot provide power to the hybrid
system in position
N.
Low Gear:
Low gear (position L) is
designed to mimic the enhanced engine
braking available in non-hybrid vehicles.
Low gear will produce high engine speeds
to provide necessary engine braking. This
is normal and will not damage your vehicle.
In low gear, the gas engine will remain on
more often than in position
D.
Reverse:
In position R, vehicle speed is
limited to 22 mph (35 km/h). Unique Hybrid Operating
Characteristics
Your vehicle behaves differently compared
to a non-hybrid. Here is a description of the
major differences:
Battery:
Your hybrid is equipped with a
high voltage battery. A cool battery ensures
battery life and provides the best possible
performance. Your hybrid high voltage
battery may periodically re-condition itself
to ensure maximum efficiency. You may
notice slight changes in driveability during
this process, but it is an important part of
your hybrid's high voltage battery
optimization features.
The high voltage battery is cooled by cabin
air drawn from vent holes in the trim panels
behind the rear seats. Avoid placing objects
at the vent holes that block airflow to the
high voltage battery.
Engine:
The engine speed in your hybrid
is not directly tied to your vehicle speed.
Your vehicle's engine and transmission are
designed to deliver the power you need at
the most efficient engine speed. During
heavy accelerations, your hybrid may reach
high engine speeds (up to 6000 RPM).
In prolonged mountainous driving, you may
see the engine tachometer changing
without your input. This is intentional and
maintains the battery charge level. You
may also notice during extended downhill
driving that your engine continues to run
instead of shutting off.
During this engine braking, the engine stays
on, but it is not using any fuel. You may also
hear a slight whine or whistle when
operating your vehicle. This is the normal
operation of the electric generator in the
hybrid system.
131
C-MAX (CCG) Unique Driving Characteristics

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?

C-MAX (CCG) Unique Driving Characteristics

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?

SAFETY PRECAUTIONS
WARNINGS
Do not overfill the fuel tank. The
pressure in an overfilled tank may
cause leakage and lead to fuel spray
and fire. The fuel system may be under
pressure. If you hear a hissing sound
near the fuel filler door (Easy Fuel
capless fuel system), do not refuel until
the sound stops. Otherwise, fuel may spray
out, which could cause serious personal
injury. Automotive fuels can cause serious
injury or death if misused or
mishandled.
The flow of fuel through a fuel pump
nozzle can produce static electricity,
which can cause a fire if fuel is
pumped into an ungrounded fuel container. Fuel ethanol and gasoline may
contain benzene, which is a
cancer-causing agent.
When refueling always shut the
engine off and never allow sparks or
open flames near the filler neck.
Never smoke or use a cell phone while
refueling. Fuel vapor is extremely
hazardous under certain conditions. Avoid
inhaling excess fumes. Observe the following guidelines when
handling automotive fuel:
•
Extinguish all smoking materials and
any open flames before refueling your
vehicle.
• Always turn off the vehicle before
refueling. •
Automotive fuels can be harmful or
fatal if swallowed. Fuel such as
gasoline is highly toxic and if
swallowed can cause death or
permanent injury. If fuel is swallowed,
call a physician immediately, even if no
symptoms are immediately apparent.
The toxic effects of fuel may not be
visible for hours.
• Avoid inhaling fuel vapors. Inhaling too
much fuel vapor of any kind can lead
to eye and respiratory tract irritation.
In severe cases, excessive or prolonged
breathing of fuel vapor can cause
serious illness and permanent injury.
• Avoid getting fuel liquid in your eyes. If
fuel is splashed in the eyes, remove
contact lenses (if worn), flush with
water for 15 minutes and seek medical
attention. Failure to seek proper
medical attention could lead to
permanent injury.
• Fuels can also be harmful if absorbed
through the skin. If fuel is splashed on
the skin, clothing or both, promptly
remove contaminated clothing and
wash skin thoroughly with soap and
water. Repeated or prolonged skin
contact with fuel liquid or vapor causes
skin irritation.
• Be particularly careful if you are taking
“Antabuse ” or other forms of disulfiram
for the treatment of alcoholism.
Breathing gasoline vapors, or skin
contact could cause an adverse
reaction. In sensitive individuals, serious
personal injury or sickness may result.
If fuel is splashed on the skin, promptly
wash skin thoroughly with soap and
water. Consult a physician immediately
if you experience an adverse reaction.

FUEL QUALITY
Note:
Use of any fuel other than those
recommended may cause powertrain
damage, a loss of vehicle performance and
repairs may not be covered under warranty.
Choosing the Right Fuel
Use only UNLEADED gasoline or
UNLEADED gasoline blended with a
maximum of 15% ethanol in your gasoline
vehicle. If your vehicle is a Flex Fuel Vehicle
(FFV), it will have a yellow bezel placed
over the fuel fill inlet.
Do not use:
• fuels containing more than 15%
ethanol or E-85 fuel
• fuels containing methanol
• fuels containing metallic based
additives, including manganese-based
compounds
• fuels containing the octane booster
additive, methylcyclopentadienyl
manganese tricarbonyl (MMT)
• leaded-fuel (The use of leaded fuel is
prohibited by law)
Note: Use of any fuel other than the
recommended fuel can cause powertrain
damage, impair the emission control system
or cause loss of vehicle performance. Any
damage to the vehicle that is caused by the
use of fuel not recommended will not be
covered under warranty.
Octane Recommendations
Regular unleaded gasoline with a pump
(R+M)/2 octane rating of 87 is
recommended. Some fuel stations offer
fuels posted as regular with an octane
rating below 87, particularly in high altitude
areas. Fuels with octane levels below 87
are not recommended. Do not be concerned if your engine
sometimes knocks lightly. However, if it
knocks heavily while you are using fuel with
the recommended octane rating, see your
authorized dealer to prevent any engine
damage.
Fuel Freshness Mode (Energi
Vehicles Only)
This feature helps keeps the fuel system
functional and the fuel fresh.
If you operate your vehicle mainly in plug-in
power mode using electricity from plugging
in without refueling, the gasoline in your
tank eventually becomes old. Old fuel can
damage the engine and fuel system.
To prevent the fuel from becoming old,
your vehicle will automatically enter fuel
freshness mode. In fuel freshness mode
operates, your vehicle will operate in hybrid
mode causing the gasoline engine to run
in order to consume the fuel in the fuel
tank.
Note:
If new fuel is not added during an 18
month period, fuel freshness mode will
consume fuel until about 1 gallon (3.8 liters)
is left in the tank.
During fuel freshness mode:
• The information display screen will
indicate that fuel freshness mode is
active.
• The vehicle will only run in hybrid mode.
EV Now will not be available.
• Most of the plug-in power will be
stored until fuel freshness mode is
completed.
Note: EV Now can resume if less than 1
gallon (3.8 liters) of fuel is left in the tank.
Note: In most cases, when the fuel level is
below 1/4 tank, refueling the vehicle will end
fuel freshness mode and EV Now will now
become available. Refueling after
consuming a full tank in fuel freshness mode
will end the mode.
136
C-MAX (CCG) Fuel and Refueling

Note:
It is recommended to use a fuel
stabilizer if you consume less than a full
tank of fuel during an 18 month period.
RUNNING OUT OF FUEL
Avoid running out of fuel because this
situation may have an adverse effect on
powertrain components.
If you have run out of fuel:
• You may need to cycle the ignition from
off to on several times after refueling
to allow the fuel system to pump the
fuel from the tank to the engine. On
restarting, cranking time will take a few
seconds longer than normal. With
keyless ignition, just start the engine.
Crank time will be longer than usual.
• Normally, adding 1 gallon (3.8 liters) of
fuel is enough to restart the engine. If
the vehicle is out of fuel and on a steep
grade, more than 1 gallon (3.8 liters)
may be required.
• The service engine soon indicator may
come on. For more information on the
service engine soon indicator, See
Symbols Glossary (page 7).
Refilling With a Portable Fuel
Container WARNINGS
Do not insert the nozzle of portable
fuel containers or aftermarket
funnels into the capless fuel system.
This could damage the fuel system and its
seal, and may cause fuel to run onto the
ground instead of filling the tank, which
could result in serious personal injury. Do not try to pry open or push open
the capless fuel system with foreign
objects. This could damage the fuel
system and its seal and cause injury to you
or others. Note:
Do not use aftermarket funnels; they
will not work with the capless fuel system
and can damage it. The included funnel has
been specially designed to work safely with
your vehicle.
When filling the vehicle ’s fuel tank from a
portable fuel container, use the funnel
included with the vehicle. In C-MAX vehicles, the funnel is located in
the rear of the vehicle inside the load
compartment.
In C-MAX Energi vehicles the funnel is
located in the rear of the vehicle, inside
storage compartment
1.
Locate the portable funnel that comes
with your vehicle.

1. Put the vehicle in park (P) and switch
the ignition 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 to open both doors
until pumping is complete. Hold the
handle higher during insertion for easier
access. 4. Once pumping is complete, slowly
remove the fuel filler nozzle. Allow
approximately five to ten 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 spill 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 you did not close the fuel fill inlet
properly, a Check Fuel Fill Inlet message
may appear in the information display.
At the next opportunity, do the following:
1. Safely pull off the road.
2. Put the vehicle in park (P) and switch the ignition off.
3. Open the fuel filler door and remove any visible debris from the fuel fill
opening.
4. Insert the fuel fill nozzle or the fuel fill funnel provided with the vehicle several
times to dislodge any debris and allow
the inlet to close properly.
If this action corrects the problem, the
message may not reset immediately. It
may take several driving cycles for the
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 or highway driving. Continuing to
drive with the message on may cause the
service engine soon lamp to turn on as
well.
Easy Fuel ™ Capless System
(Energi Vehicles Only) WARNING
The fuel system may be under
pressure. If you hear a hissing sound
near the fuel filler door, do not refuel
until the sound stops. Otherwise, fuel may
spray out, which could cause serious
personal injury. 139
