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.

STEERING
Electric Power Steering
WARNING:The electric power steering system has diagnostic
checks that continuously monitor the system to ensure proper
operation. When a system error is detected a steering message will
appear in the information display.
WARNING:The electric power steering system has diagnostic
checks that continuously monitor the system to ensure proper
operation of the electronic system. When an electronic error is
detected, a message will be displayed in the information display. If this
happens, stop the vehicle in a safe place, and turn off the engine. After
at least 10 seconds, reset the system by restarting the engine, and
watch the information display for a steering message. If a steering
message returns, or returns while driving, take the vehicle to your
dealer to have it checked.
WARNING:Obtain immediate service if a system error is
detected. You may not notice any difference in the feel of your
steering, but a serious condition may exist. Failure to do so may result
in loss of steering control.
Your vehicle is equipped with an electric power-assisted steering system.
There is no fluid reservoir to check or fill.
If your vehicle loses electrical power while you are driving (or if the
ignition is turned off), you can steer the vehicle manually, but it takes
more effort. Extreme continuous steering may increase the effort it
takes for you to steer. This occurs to prevent internal overheating and
permanent damage to your steering system. If this should occur, you
will neither lose the ability to steer the vehicle manually nor will it cause
permanent damage. Typical steering and driving maneuvers will allow the
system to cool and steering assist will return to normal.
When a steering system error is detected, steering messages may appear
in the information display.

The coolant concentration should be maintained at 50%.
Note:For best results, coolant concentration should be tested with a
refractometer such as Rotunda tool ROB75240 available from your
dealer. Ford does not recommend the use of hydrometers or coolant test
strips for measuring coolant concentrations.
Note:It is very important to use prediluted coolant meeting the Ford
specification in order to avoid plugging the small coolant passageways.
Use of concentrated coolant and water may cause coolant passageway
plugging and void the warranty. See the technical specifications chart in
theCapacities and Specificationschapter.
Note:Automotive fluids are not interchangeable; do not use
coolant/antifreeze or windshield washer fluid outside of its specified
function and vehicle location.
Adding Coolant
WARNING:Do not add engine coolant when the engine is hot.
Steam and scalding liquids released from a hot cooling system
can burn you badly. Also, you can be burned if you spill coolant on hot
engine parts.
WARNING:Do not put engine coolant in the windshield washer
fluid container. If sprayed on the windshield, engine coolant
could make it difficult to see through the windshield.
WARNING:To reduce the risk of personal injury, make sure the
engine is cool before unscrewing the coolant pressure relief cap.
The cooling system is under pressure; steam and hot liquid can come
out forcefully when the cap is loosened slightly.
WARNING:Do not add coolant further than the MAX mark.
Note:Do not use stop leak pellets or cooling system sealants/additives
as they can cause damage to the cooling and/or heating systems. This
damage would not be covered under your vehicle’s warranty.

Note:During normal vehicle operation, the coolant may change color
from orange to pink or light red. As long as the coolant is clear and
uncontaminated, this color change does not indicate the coolant has
degraded nor does it require the coolant to be drained, the system
to be flushed, or the coolant to be replaced.
•DO NOT MIX different colors or types of coolant in your vehicle. Make
sure the correct coolant is used. Mixing of coolants may harm your
cooling system. The use of an improper coolant may harm engine,
inverter system controller, and cooling system components and may
void the warranty.
•
In case of emergency, a large amount of water without engine coolant
may be added to the engine cooling system only in order to reach a
vehicle service location. In this instance, the engine cooling system must
be drained, chemically cleaned with Motorcraft® Premium Cooling
System Flush, and refilled with prediluted engine coolant as soon as
possible. Water alone (without engine coolant) can cause engine damage
from corrosion, overheating, or freezing. DO NOT use this method for
the inverter system controller cooling system. The inverter system
controller cooling system operates close to ambient temperature, and is
susceptible to freezing in any subfreezing environment in the absence of
coolant.
•Do not use alcohol, methanol, brine or any engine coolants mixed with
alcohol or methanol antifreeze (coolant). Alcohol and other liquids can
cause engine damage from overheating or freezing.
•Do not add extra inhibitors or additives to the coolant. These can be
harmful and compromise the corrosion protection of the coolant.
Adding Engine Coolant
1. Remove the Easy Fuel funnel from the storage compartment. Refer to
Running Out of Fuelfor the location of the Easy Fuel funnel.
2. Unscrew the engine coolant reservoir cap slowly. Any pressure will
escape as you unscrew the cap.
3. Position the Easy Fuel funnel in the engine coolant reservoir opening.
Push the Easy Fuel funnel neck fully into the engine coolant reservoir,
past the vent tube, in order to avoid pouring the coolant into the vent
tube and spilling the coolant on the ground.
4. Add prediluted engine coolant to the engine coolant reservoir. Make
sure that the level is between the MIN and MAX marks on the engine
coolant reservoir. Use prediluted engine coolant meeting the Ford
specification. See the technical specifications chart in theCapacities
and Specificationschapter.

Tips for Use of the Temporary Mobility Kit
Read the following list of tips to make sure safe operation of the
temporary mobility kit:
•Before operating the temporary mobility kit, make sure your vehicle is
safely off the road and away from moving traffic. Turn on the hazard
lights.
•Always set the parking brake to make sure the vehicle does not move
unexpectedly.
•
Do not remove any foreign objects, such as nails or screws, from the
tire.
•When using the temporary mobility kit, leave the engine running
(only if the vehicle is outdoors or in a well-ventilated area) so the
compressor does not drain the vehicle’s battery.
•Do not allow the compressor to operate continuously for more than
15 minutes; this will help prevent the compressor from overheating.
•Never leave the temporary mobility kit unattended when it is
operating.
•Sealant compound contains latex. Make sure that you use the
non-latex gloves provided to avoid an allergic reaction.
•Keep the temporary mobility kit away from children.
•Only use the temporary mobility kit when the ambient temperature is
between -22°F (–30°C) and 158°F (70°C).
•Only use the sealing compound before the use by date. The use by
date is on the lower right hand corner of the label located on the
sealant canister (bottle).Note:Check the use by date regularly and
replace the canister after four years.
•Do not store the temporary mobility kit unsecured inside the
passenger compartment of the vehicle as it may cause injury during a
sudden stop or collision. Always store the kit in its original location.
•
After sealant use, the tire pressure monitoring system sensor and valve
stem on the wheel must be replaced by an authorized Ford dealer.
•When inflating a tire or other objects, use the black air hose only. Do not
use the transparent hose which is designed for sealant application only.
•Operating the temporary mobility kit could cause an electrical
disturbance in radio, CD, and DVD player operation (if equipped).

Ford Motor Company has recommended maintenance intervals for
various parts and component systems based upon engineering testing.
Ford Motor Company relies upon this testing to determine the most
appropriate mileage for replacement of oils and fluids to protect your
vehicle at the lowest overall cost to you and recommends against
maintenance schedules that deviate from the scheduled maintenance
information.
Ford strongly recommends using only genuine Ford, Motorcraft® or
Ford-authorized remanufactured replacement parts because they are
engineered for your vehicle.
Additives and Chemicals
Ford Motor Company recommended additives and chemicals are listed in
this book and in theWorkshop Manual.Additional chemicals or additives
not approved by Ford Motor Company are not recommended as part of
normal maintenance. Please consult your warranty information.
Oils, Fluids and Flushing
In many cases, fluid discoloration is a normal operating characteristic
and, by itself, does not necessarily indicate a concern or that the fluid
needs to be changed. However, discolored fluids that also show signs of
overheating and/or foreign material contamination should be inspected
immediately by a qualified expert such as the factory-trained technicians
at your dealership. Your vehicle’s oils and fluids should be changed at the
specified intervals or in conjunction with a repair. Flushing is a viable
way to change fluid for many vehicle sub-systems during scheduled
maintenance. It is critical that systems are flushed only with new fluid
that is the same as that required to fill and operate the system, or using
a Ford-approved flushing chemical.
