Note:
Some warning indicators appear in
the information display and function the
same as a warning lamp but do not display
when you start your vehicle.
Anti-Lock Braking System If it lights when you are driving,
this indicates a malfunction. You
will continue to have normal
braking (without anti-lock braking system)
unless the brake system warning lamp also
lights. Have the system checked by an
authorized dealer.
Battery If it lights while driving, this
indicates a malfunction. Switch
off all unnecessary electrical
equipment and have the system checked
by an authorized dealer immediately.
Brake System Lights when you engage the
parking brake with the ignition
on.
If it lights when you are driving, check that
you do not have the parking brake
engaged. If you do not have the parking
brake engaged, this indicates low brake
fluid level or a brake system malfunction.
Have the system checked immediately by
an authorized dealer. WARNING
Driving your vehicle with the warning
lamp on is dangerous. A significant
decrease in braking performance
may occur. It will take you longer to stop
your vehicle. Have your vehicle checked by
your authorized dealer immediately. Driving
extended distances with the parking brake
engaged can cause brake failure and the
risk of personal injury. Cruise Control (If Equipped)
Lights when you switch on this
feature.
Direction Indicator Lights when you switch on the
left or right direction indicator or
hazard warning flasher. If the
indicators stay on or flash faster, check for

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 AC
electrical source.
We recommend that you do the following
for a safe and correct operation:
•
Use a 16-gauge outdoor extension cord
that is product certified by
Underwriter ’s Laboratory (UL) or
Canadian Standards Association
(CSA). This extension cord must be
suitable for use outdoors, in cold
temperatures, and be clearly marked
Suitable for Use with Outdoor
Appliances. Do not use an indoor
extension cord outdoors. This 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 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.
• Check for heat anywhere in the
electrical hookup once the system has
been operating for approximately 30
minutes. •
Make sure the system is unplugged and
properly stowed before starting and
driving your vehicle. Make sure the
protective cover seals the prongs of the
block heater cord plug when not in use.
• Make sure the heater system is
checked for proper operation before
winter.
Using the Engine Block Heater
Make sure the receptacle terminals are
clean and dry prior to use. Clean them with
a dry cloth if necessary.
The heater uses 0.4 to 1.0 kilowatt-hours
of energy per hour of use. The system does
not have a thermostat. It achieves
maximum temperature after
approximately three hours of operation.
Using the heater longer than three hours
does not improve system performance and
unnecessarily uses electricity.

C-MAX (CCG) Canada/United States of America, enUSA, Second Printing Starting and Stopping the Engine

Note:
Cold temperatures will affect the
engine warm up time and the low engine
use mode may operate more frequently. Note:
An oil change is not required but gives
you the option of not running a low engine
use cycle. Resetting the oil life monitoring
system will suspend the low engine use
mode.
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 switch the key on, high voltage contactors inside the battery are
closed to make the electricity available to the motor and 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.
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
make sure that the emissions components are warm enough to minimize tailpipe
emissions. 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 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?

Low Engine Use (If Equipped)
The low engine use mode is equipped on
Energi models only. The low engine use
mode keeps the engine oil quality in good
condition when you drive your vehicle with
limited engine use. If your vehicle is in low
engine use mode when you start the
vehicle, a message appears in the
information display. When your vehicle is
in low engine use mode, your vehicle runs
the engine as necessary.
Selecting EV Now mode when your vehicle
is in the low engine use mode suspends
the low engine use mode for as long as you
continue driving your vehicle. The low
engine use mode resumes the next time
you start your vehicle.
Changing the engine oil and resetting the
oil life monitoring system suspends the low
engine use mode.
ENGINE COOLANT CHECK WARNINGS
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. 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. 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. Do not add coolant further than the
MAX
mark. Engine Coolant and Inverter
System Controller Coolant
Your vehicle has 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 the
scheduled maintenance information. See
Scheduled Maintenance
(page 420).
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. See
Adding Engine
Coolant in this chapter.
Maintain coolant concentration within
48% to 50%, which equates to a freeze
point between -30°F (-34°C) and -34°F
(-37°C).
Note: For best results, coolant
concentration should be tested with a
refractometer such as Robinair® Coolant
and Battery Refractometer 75240. We do
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
or 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 the scheduled maintenance
information. See Scheduled
Maintenance (page 420).
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. See
Adding Inverter
System Controller Coolant in this chapter.
Maintain coolant concentration within
48% to 50%, which equates to a freeze
point between -30°F (-34°C) and -34°F
(-37°C).
Note: For best results, coolant
concentration should be tested with a
refractometer such as Robinair® Coolant
and Battery Refractometer 75240. We do
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
or antifreeze or windshield washer fluid
outside of its specified function and vehicle
location.
Adding Coolant
Note: Do not use stop leak pellets, cooling
system sealants, or additives as they can
cause damage to the cooling 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.
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
Capacities and Specifications (page 275
).
• 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 the 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
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.
219
C-MAX (CCG) Canada/United States of America, enUSA, Second Printing Maintenance

Vehicles driven year-round in non-extreme
climates should use prediluted coolant
meeting the Ford specification for
optimum cooling system and engine
protection.
What You Should Know About Fail-
Safe Cooling
If the engine coolant supply is depleted,
this feature allows the vehicle to be driven
temporarily before incremental component
damage is incurred. The
“fail-safe”
distance depends on ambient
temperatures, vehicle load and terrain.
How Fail-Safe Cooling Works
If the engine begins to overheat, the engine
coolant temperature gauge will move to
the red (hot) area and: The coolant temperature
warning light will illuminate.
The service engine soon
indicator will illuminate.
If the engine reaches a preset
over-temperature condition, the engine
will automatically switch to alternating
cylinder operation. Each disabled cylinder
acts as an air pump and cools the engine.
When this occurs the vehicle will still
operate. However:
• The engine power will be limited.
• The air conditioning system will be
disabled.
Continued operation will increase the
engine temperature and the engine will
completely shut down, causing steering
and braking effort to increase.
Once the engine temperature cools, the
engine can be re-started. Take your vehicle
to an authorized dealer 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 while the engine is running or hot.
Note:
Driving the vehicle without repairing
the engine problem increases the chance of
engine damage. Take your vehicle to an
authorized dealer as soon as possible.
You have limited engine power when in the
fail-safe mode, so drive the vehicle with
caution. The vehicle will not be able to
maintain high-speed operation and the
engine will run rough. Remember that the
engine is capable of completely shutting
down automatically to prevent engine
damage, therefore:
1. Pull off the road as soon as safely possible and turn off the engine.
2. Arrange for the vehicle to be taken to an authorized dealer.
3. If this is not possible, wait a short period for the engine to cool.
4. Check the coolant level and replenish if low.
5. Re-start the engine and take your vehicle to an authorized dealer.
