2013 FORD C MAX engine

PLUG-IN POWER MODE AND HYBRID MODE (C-MAX ENERGI ONLY)
C-MAX Energi vehicles must be plugged in regularly for optimal use of
the high voltage battery’s extended range capability. When you charge
your vehicle you add electrical energy which is then used to propel the
vehicle in Plug-in Power Mode. Your estimated electric range in this
mode is shown in an enhanced battery gauge on the instrument panel
display. Electric only operation is maximized in plug-in power mode.
System conditions may require engine operation, however, plug-in power
will be used whenever possible.
When your plug-in power has been depleted, the powertrain system will
automatically switch to hybrid mode. Your battery gauge will show an
electric range of zero before transitioning to a simple battery graphic
upon entering hybrid mode. Hybrid mode uses both the gasoline engine
and electric motor to power your vehicle and maximize fuel economy as
with C-MAX Hybrid.
EV MODES (C-MAX ENERGI ONLY)
Your vehicle contains selectable EV modes through the EV
button on the center console.
These modes are available when the vehicle can run under high voltage
battery power. With the vehicle in driving mode you can change EV
modes with each press of the EV button. The current mode will be
displayed in the left hand instrument cluster screen.
Auto EV
This mode provides an automatic use of high-voltage battery
power during the drive, staying in electric mode when possible
and running the engine when needed. This mode will be the
only one available if the plug in power has been depleted.

EV Now
This mode provides an electric only driving experience using
plug-in power. The left-hand information display will change to an
Energy Use screen that supplies EV specific tools and functions.
The vehicle may accelerate more slowly and the top speed may be lower
than in Auto EV. At any time, the engine may be enabled by using one of
the following methods:
1. Press the OK button on the left 5–way steering wheel control while
viewing the EV screen. The vehicle will automatically exit override after
the timer has expired and the engine shuts down.
2.
Press the accelerator pedal fully. A pop up message statingPress OK to
Enable Enginewill appear. Press OK on the left steering wheel button to
activate as needed. The message will disappear if the accelerator pedal is
released.
3. Press the EV button. This will change the mode to EV Later and
permit engine operation
The vehicle may automatically enter Engine Enabled mode if system
conditions require it. A messageEngine Enabled for System
Performancewill display if this occurs. This is normal function, and
your vehicle will return to EV Now when possible.
The vehicle may enter Enable Engine mode if the climate control is in a
defrost mode and the outside temperature is cold. A messageEngine
Enabled Due to Defrostwill display if this occurs. If defrost is not
needed, select a different climate control mode to permit EV Now.
There is a blue EV icon that is displayed in the left-hand information
display when EV Now is enabled. If the vehicle is in the Engine Enabled
mode, the EV icon will be yellow.
EV Now will automatically exit when the Plug in power has been depleted.
EV Later
This mode saves the high voltage battery plug in power for
future use (for example, your initial drive is at high speeds on
open roads, but later your drive will be at low speeds in an
urban area). Your vehicle will run the engine as needed and
keep most of the high voltage battery plug in power for later use in Auto
EV or EV Now mode.
There is a white EV Later icon that appears on the left-hand information
display when EV Later is enabled.

HYBRID VEHICLE OPERATION (C-MAX HYBRID AND C-MAX ENERGI)
This hybrid vehicle combines electric and gasoline propulsion to provide
breakthrough performance and improved efficiency. Familiarizing yourself
with these unique characteristics will provide an optimal driving experience
from your new vehicle.
Note:You may notice higher engine speeds upon start-up. This
temporary condition is normal and necessary to heat up the cabin and
minimize emissions.
Starting:When you start your vehicle, a green ready indicator
light will appear in the lower right portion of the instrument
cluster and a ready to drive message will appear in the middle
of the left cluster screen, letting you know that the vehicle is ready for
driving.
The engine may not start because this hybrid vehicle is equipped with
silent key start. This fuel saving feature allows your vehicle to be
ready-to-drive without requiring the gas engine to be running. This
indicator will remain on while the vehicle is on, whether the engine is
running or not to indicate the vehicle is capable of movement (using its
electric motor, engine, or both). Typically, the engine will not start unless
the vehicle is cold, a climate control change is requested, or the
accelerator is pressed.
Driving:The gas engine automatically starts and stops to provide power
when it’s needed and to save fuel when it’s not. While coasting at low
speeds, coming to a stop, or standing, the gas engine normally shuts
down and the vehicle operates in electric-only mode. Conditions that
may cause the engine to start up or remain running include:
•considerable vehicle acceleration
•vehicle speed above 60 mph (96 km/h) For C-MAX Energi vehicles,
you can drive up to 85 mph (137 km/h) in EV mode.
•ascending a hill
•charge level of high voltage battery is low
•very high or low outside temperature (to provide system cooling or
heating) For C-MAX Energi vehicles, climate control demands by
passengers do not directly cause the engine to run. This only occurs
when the high voltage battery charge is low.
•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 positionNfor
extended periods of time because this will discharge your high voltage
battery and decrease fuel economy. The engine will not start, and cannot
provide power to the hybrid system in positionN.
Low Gear:Low gear (positionL) 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 positionD.
Reverse:In positionR, vehicle speed is limited to 22 mph (35 km/h).
Unique Hybrid Operating Characteristics
Your hybrid 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 drivability
during this process, but it’s 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 which block air flow to the high voltage battery.
The high voltage battery is located behind the rear seat or underneath
the load floor. The rear seats can be lowered to increase cargo space.
If the vehicle is left inoperative for over 31 days, it may be necessary
to jump start the vehicle. Refer toJump starting the vehiclein the
Roadside Emergencieschapter and also seeLow and high voltage
battery – storagein theVehicle Carechapter.

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’s 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.
During certain events (such as vehicle servicing) your low voltage
(underhood) 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 vehicle
computer housed with the transmission and it commands a portion of
the brake energy stored 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, fuel economy can be significantly impacted
by your driving habits, accessory usage, temperature and terrain.
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, better fuel economy is achieved 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.
Note:Frequent destinations are learned by your vehicle after two to
four weeks of use. These destinations can be cleared with a Lifetime
Summary 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
Question Answer
What are the
series of clicks
from the cargo
area when I first
turn the key in
the ignition?The high voltage battery is electrically isolated from
the rest of the vehicle when the key is off. When
the key is turned 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.
Why does the
engine sometimes
start at key-on?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 C-MAX Energi vehicles, engine on is not
required to operate these functions.)

Question Answer
Why does it take
a long time
before the engine
shuts down?There are several reasons the engine stays on for an
extended amount of time when it is first started.
One common reason is to ensure that the emissions
components are warm enough to minimize tailpipe
emissions. As the climate gets cooler, this engine-on
time is extended.
Why does my
engine never
shut down
above 60 mph
(96 km/h)?The engine is required to turn on above this speed
to protect the transmission hardware. (For C-MAX
Energi vehicles, you can travel up to 85 mph
[137 km/h] in EV mode.)
Why does my
engine stay
on when it’s
extremely cold
outside?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 maintain the correct minimum temperature.
(For C-MAX Energi vehicles, this is not required to
maintain cabin conditions.)
Why does my
engine rev up so
high sometimes
when I
accelerate?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
characteristics of the Atkinson engine cycle and the
eCVT transmission technology that help maximize
your hybrid’s fuel economy.

Question Answer
What is the fan
noise I hear from
the rear of my
hybrid?The fan noise comes from a fan located inside 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
engine oil change
service interval?The engine oil should be changed every 10000 miles
(16000 km) under normal operating conditions. See
theScheduled maintenance information.
Can I put E15 or
E85 in my
vehicle, and how
will it affect my
fuel economy?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).
How long will my
high voltage
battery last?
Does it need
maintenance?The high voltage battery system is designed to last
the life of the vehicle and requires no maintenance.
Can you charge
the battery with
aplugintoan
A/C outlet?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 I tow the
hybrid behind my
motor home with
all four wheels
down?Yes. Your hybrid vehicle can be flat-towed without
modification. See theRecreational towingsection
in theTowingchapter for more information.
