•Charge Level — This indicates the State of Charge of the battery.
Additionally, for Energi vehicles the option only applies for the Hybrid
Mode battery display (simple battery graphic). The Plug-in Power
Mode battery will always show the charge level with associated
remaining EV range.
•Inst. Fuel — Shows instantaneous fuel usage.
•Coolant Temp – Indicates engine coolant temperature. At normal
operating temperature, the level indicator will be white and will
be in the normal range (between H and C). If the engine coolant
temperature exceeds the normal range, the level indicator will change
to red to indicate that the engine is overheating. Stop the vehicle as
soon as safely possible, turn off the vehicle and let the engine cool.
The thermometer indicator next to the gauge will illuminate in blue or
white to indicate the following:
•
Blue thermometer : This indicates that the hybrid system is not
warm enough to allow EV operation. The gasoline engine will run
continuously when the indicator is blue. During silent key start mode,
the thermometer indicator will be blue, but the gasoline engine will not
run. This is the result of the vehicle computer allowing the engine to be
cooler during the silent key start period. This is normal operation and
does not indicate a problem with your vehicle. After the first engine
start the indicator will turn white when the gasoline engine is warm
enough to turn off.
•White thermometer : This indicates that the hybrid system is warm
enough to allow EV operation. If the vehicle operates on battery
power long enough, it is possible that the gasoline engine may need to
run to keep the system warm. In this case, the thermometer indicator
will revert back to blue.
Note:Trip data, average fuel economy and average speed cannot be
reset in MyView. You can reset this data from other screens where it is
shown.

ENGINE BLOCK HEATER (IF EQUIPPED)
WARNING:Failure to follow engine block heater instructions
could result in property damage or physical injury.
WARNING:Do not use your heater with ungrounded electrical
systems or two-pronged (cheater) adapters. There is a risk of
electrical shock.
Note:The heater is most effective when outdoor temperatures are below
0°F (-18°C).
The heater acts as a starting aid by warming the engine coolant. This
allows the climate control system to respond quickly. The equipment
includes a heater element (installed in the engine block) and a wire
harness. You can connect the system to a grounded 120 volt A/C
electrical source.
We recommend that you do the following for safe and correct operation:
•
Use a 16-gauge outdoor extension cord that is product certified by
Underwriter’s Laboratory or Canadian Standards Association. This
extension cord must be able to be used outdoors, in cold temperatures,
and be clearly markedSuitable for Use with Outdoor Appliances.
Never use an indoor extension cord outdoors; it could result in an
electric shock or become a fire hazard.
•Use as short an extension cord as possible.
•Do not use multiple extension cords.
•Make sure that when in operation, the extension cord plug and the
heater cord plug connections are free and clear of water. This could
cause an electric shock or fire.
•
Make sure your vehicle is parked in a clean area, clear of combustibles.
•Make sure the heater, heater cord and extension cord are firmly
connected.

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.

COOLANT
Engine Coolant and Inverter System Controller Coolant
Your vehicle is equipped with two separate cooling systems. One is for
cooling the engine and one is for cooling the inverter system controller
that is specific to the hybrid operating system. The two systems operate
similarly, with the inverter system controller cooling system generally
operating at a lower temperature and pressure.
Checking the Engine Coolant
When the engine is cold, check the concentration and level of the engine
coolant at the intervals listed in theScheduled Maintenance Information.
Note:Make sure that the level is between the MIN and MAX marks on
the engine coolant reservoir.
Note:Coolant expands when it is hot. The level may extend beyond the
MAX mark.
Note:If the level is at the MIN mark, below the MIN mark, or empty,
add prediluted coolant immediately. Refer toAdding Engine Coolantin
this chapter.
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:Automotive fluids are not interchangeable; do not use engine
coolant/antifreeze or windshield washer fluid outside of its specified
function and vehicle location.
Checking the Inverter System Controller Coolant
When the engine is cold, check the concentration and level of the
inverter system controller coolant at the intervals listed in theScheduled
Maintenance Information.
Note:Make sure that the level is between the MIN and MAX marks on
the inverter system controller coolant reservoir.
Note:Coolant expands when it is hot. The level may extend beyond the
MAX mark.
Note:If the level is at the MIN mark, below the MIN mark, or empty,
add prediluted coolant immediately. Refer toAdding Inverter System
Controller Coolantin this chapter.

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.
