Engage
Engage provides separate gauges for
engine power and high voltage battery
power in kilowatts (kW). The engine power
gauge fill is white and the high voltage
battery power gauge fill is blue. You can
also see an instantaneous fuel economy
gauge. When your vehicle is operating on
battery power only, you will see EV
displayed and the gauges will appear in
blue.
Empower
Empower provides a power demand gauge
in kilowatts (kW) which includes an engine
on or off threshold.
•
When your vehicle is operating with
battery power only (below the
threshold), you will see EV displayed
and the gauge fill is blue.
• When your vehicle is operating with
both the engine and the high voltage
battery providing power the gauge fill
is white.
• When power demand surpasses the
amber indicator, this level of demand
and associated fuel economy displays
in amber.
• When the engine is on, reducing power
demand to less than the threshold will
allow the engine to turn off.
You can also see an instantaneous fuel
economy gauge.
Note: You can reset your average fuel
economy by pressing and holding the OK
button on the left hand steering wheel
controls.
MyView
You can choose what to display in this
view. Selecting
Change MyView in the

Unique content available in MyView:
• Accessory Power — Indicates electrical
power demands from your vehicle ’s
accessory systems. Accessories use
power but do not contribute to
propelling your vehicle. The gauge
separately displays power demand in
kilowatts (kW) for climate and other
accessories. Climate includes the
power being used by high voltage
climate control components such as
the electric A/C compressor. Other
includes all power being used by the
low voltage accessories (cabin fans,
headlights, heated seats, etc.).
• 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 your vehicle
as soon as safely possible, turn your
vehicle off and let the engine cool.
• Tach rpm x 1000 — When the gasoline
engine is running, the tachometer
gauge displays the engine speed in
revolutions per minute (RPM). When
your vehicle is operating on battery
power only with the engine off, EV
displays and the tachometer is greyed
out.

Answer
Question
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 make sure 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 main- tain the correct coolant temperature.
Why does my engine stay on when it is
extremely cold outside?
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 when
driving at a steady speed. These are charac- teristics of the Atkinson engine cycle and the transmission technology that helpmaximize 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 10,000 mi
(16,000 km) 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?

C-MAX / C-MAX Hybrid (CCG) Canada/United States of America, enUSA, Edition date: 201707, Second Printing Unique Driving Characteristics

To prevent engine damage under these
conditions customers should follow these
steps:
•
Drive your vehicle at full engine
temperature for 15 to 30 minutes.
• Drive your vehicle at highway speeds.
• Drive your vehicle with the defroster
(hybrid vehicles) at full.
We recommend frequent oil changes.
Follow severe duty cycle in the
maintenance guide. This helps remove the
moisture contaminated oil from the engine.
Cold Weather Operation
To determine if the shortened oil change
interval or warming of the engine is
sufficient, clean and check the oil fill cap
on a regular basis. This will confirm that
the thick milky substance is not returning.
When extreme cold weather and sub-zero
conditions exist, fuel may be found in the
engine oil. This is caused by the engine not
reaching its full engine temperature.
In this situation, carry out the above steps
to prevent engine damage.
OIL CHANGE INDICATOR
RESET (If Equipped)
Only reset the system after changing the
engine oil and oil filter.
Resetting the Oil Life Monitoring
System
1. Switch the ignition on. Do not start the
engine.
2. Fully press the accelerator and brake pedals at the same time.
3. Keep the accelerator and brake pedals
fully pressed. 4. After three seconds, a message
appears confirming that the reset is in
progress.
5. After 25 seconds, a message appears confirming that the reset is complete.
6. Release the accelerator and brake pedals.
7. Switch the ignition off.
ENGINE COOLANT CHECK WARNINGS
Never remove the coolant reservoir
cap when the engine is running or
hot.
Do not put coolant in the windshield
washer reservoir. If sprayed on the
windshield, coolant could make it
difficult to see through the windshield. 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 you loosen the cap
slightly. Do not add coolant further than the
MAX mark.
Your vehicle has two separate cooling
systems. One for cooling the engine and a
separate system 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.
When the engine is cold, check the
concentration and level of the coolant at
the intervals listed in the scheduled
maintenance information. See Scheduled
Maintenance
(page 415).
216
C-MAX / C-MAX Hybrid (CCG) Canada/United States of America, enUSA, Edition date: 201707, Second Printing Maintenance

Note:
Make sure that the coolant level is
between the MIN and the MAX marks on
the coolant reservoir.
Note: Coolant expands when it is hot. The
level may extend beyond the
MAX mark.
Maintain coolant concentration within
48% to 50%, which equates to a freeze
point between -30°F (-34°C) and -34°F
(-37°C). Coolant concentration should be
checked using a refractometer. We do not
recommend the use of hydrometers or
coolant test strips for measuring coolant
concentration.
Adding Coolant WARNINGS
Do not add engine coolant when the
engine is hot. Failure to follow this
instruction could result in personal
injury. Never remove the coolant reservoir
cap when the engine is running or
hot.
Note:
Automotive fluids are not
interchangeable. Do not use coolant or
windshield washer fluid outside of its
specified function and vehicle location.
Note: Do not use stop leak pellets, cooling
system sealants, or non-specified additives
as they can cause damage to the engine
cooling or heating systems. Resulting
component damage may not be covered by
the vehicle Warranty. It is very important to use prediluted
coolant approved to the correct
specification in order to avoid plugging the
small passageways in the engine cooling
system. See Capacities and
Specifications (page 274). Do not mix
different colors or types of coolant in your
vehicle. Mixing of engine coolants or using
an incorrect coolant may harm the engine
or cooling system components and may
not be covered by the vehicle Warranty.
Note: If prediluted coolant is not available,
use the approved concentrated coolant
diluting it to 50/50 with distilled water. See
Capacities and Specifications (page 270).
Using water that has not been deionized
may contribute to deposit formation,
corrosion and plugging of the small cooling
system passageways.
Note: Coolants marketed for all makes and
models may not be approved to Ford
specifications and may cause damage to
the cooling system. Resulting component
damage may not be covered by the vehicle
Warranty.
If the coolant level is at or below the
minimum mark, add prediluted coolant
immediately.
To top up the coolant level do the
following:
1. Unscrew the cap slowly. Any pressure escapes as you unscrew the cap.
2. Add prediluted coolant approved to the correct specification. See
Capacities and Specifications (page
270
).
3. Add enough prediluted coolant to reach the correct level.
4. Replace the coolant reservoir cap, turn
it clockwise until you feel a strong
resistance.
217
C-MAX / C-MAX Hybrid (CCG) Canada/United States of America, enUSA, Edition date: 201707, Second Printing Maintenance

5. Check the coolant level in the coolant
reservoir the next few times you drive
your vehicle. If necessary, add enough
prediluted engine coolant to bring the
coolant level to the correct level.
If you have to add more than 1.1 qt (1 L) of
engine coolant per month, have your
vehicle checked as soon as possible.
Operating an engine with a low level of
coolant can result in engine overheating
and possible engine damage.
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.
In case of emergency, you can add a large
amount of water without engine coolant
in order to reach a vehicle service location.
In this instance, qualified personnel:
1. Must drain the cooling system.
2. Chemically clean the cooling system.
3. Refill with prediluted coolant as soon as possible.
Water alone, without coolant, can cause
engine damage from corrosion,
overheating or freezing.
Do not use the following as a coolant
substitute:
• Alcohol.
• Methanol.
• Brine.
• Any coolant mixed with alcohol or
methanol antifreeze.
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.
Recycled Coolant
We do not recommend the use of recycled
coolant as an approved recycling process
is not yet available.
Dispose of used engine coolant in an
appropriate manner. Follow your
community's regulations and standards
for recycling and disposing of automotive
fluids.
Severe Climates
If you drive in extremely cold climates:
•
It may be necessary to increase the
coolant concentration above 50%.
• A coolant concentration of 60%
provides improved freeze point
protection. Coolant concentrations
above 60% decrease the overheat
protection characteristics of the
coolant and may cause engine
damage.
If you drive in extremely hot climates:
• You can decrease the coolant
concentration to 40%.
• Coolant concentrations below 40%
decrease the freeze and corrosion
protection characteristics of the
coolant and may cause engine
damage.
Vehicles driven year-round in non-extreme
climates should use prediluted coolant for
optimum cooling system and engine
protection.
218
C-MAX / C-MAX Hybrid (CCG) Canada/United States of America, enUSA, Edition date: 201707, Second Printing Maintenance

Coolant Change
At specific mileage intervals, as listed in
the scheduled maintenance information,
the coolant should be changed. Add
prediluted coolant approved to the correct
specification. See Capacities and
Specifications (page 270).
Fail-Safe Cooling
Fail-safe cooling allows you to temporarily
drive your vehicle before any incremental
component damage occurs. The fail-safe
distance depends on ambient
temperature, vehicle load and terrain.
How Fail-Safe Cooling Works
If the engine begins to overheat, the
coolant temperature gauge moves toward
the red zone: A warning lamp illuminates and
a message may appear in the
information display.
If the engine reaches a preset
over-temperature condition, the engine
automatically switches to alternating
cylinder operation. Each disabled cylinder
acts as an air pump and cools the engine.
When this occurs, your vehicle still
operates, however:
• Engine power is limited.
• The air conditioning system turns off.
Continued operation increases the engine
temperature, causing the engine to
completely shut down. Your steering and
braking effort increases in this situation.
When the engine temperature cools, you
can re-start the engine. Have your vehicle
checked as soon as possible to minimize
engine damage. When Fail-Safe Mode Is Activated WARNINGS
Fail-safe mode is for use during
emergencies only. Operate your
vehicle in fail-safe mode only as long
as necessary to bring your vehicle to rest
in a safe location and seek immediate
repairs. When in fail-safe mode, your
vehicle will have limited power, will not be
able to maintain high-speed operation, and
may completely shut down without
warning, potentially losing engine power,
power steering assist, and power brake
assist, which may increase the possibility
of a crash resulting in serious injury. Never remove the coolant reservoir
cap when the engine is running or
hot.
Your vehicle has limited engine power
when in the fail-safe mode, drive your
vehicle with caution. Your vehicle does not
maintain high-speed operation and the
engine may operate poorly.
Remember that the engine is capable of
automatically shutting down to prevent
engine damage. In this situation:
1. Pull off the road as soon as safely
possible and switch the engine off.
2. If you are a member of a roadside assistance program, we recommend
that you contact your roadside
assistance service provider.
3. If this is not possible, wait a short period for the engine to cool.
4. Check the coolant level. If the coolant level is at or below the minimum mark,
add prediluted coolant immediately.
5. When the engine temperature cools, you can re-start the engine. Have your
vehicle checked as soon as possible to
minimize engine damage.
