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.

CHANGING THE 12V BATTERY
WARNINGS
Batteries normally produce explosive
gases which can cause personal
injury. Therefore, do not allow
flames, sparks or lighted substances to
come near the battery. When working near
the battery, always shield your face and
protect your eyes. Always provide correct
ventilation. When lifting a plastic-cased battery,
excessive pressure on the end walls
could cause acid to flow through the
vent caps, resulting in personal injury and
damage to the vehicle or battery. Lift the
battery with a battery carrier or with your
hands on opposite corners. Keep batteries out of reach of
children. Batteries contain sulfuric
acid. Avoid contact with skin, eyes or
clothing. Shield your eyes when working
near the battery to protect against possible
splashing of acid solution. In case of acid
contact with skin or eyes, flush
immediately with water for a minimum of
15 minutes and get prompt medical
attention. If acid is swallowed, call a
physician immediately. Battery posts, terminals and related
accessories contain lead and lead
compounds. Wash hands after
handling. Your vehicle has a Motorcraft®
maintenance-free battery which normally
does not require additional water during
its life of service.
Note:
If your vehicle's battery has a cover
or shield, make sure it is reinstalled after the
battery has been cleaned or replaced.
Note: See an authorized dealer for low
voltage battery access, testing, or
replacement. When a low voltage battery replacement
is necessary, see an authorized dealer to
replace the low voltage battery with a Ford
recommended replacement low voltage
battery that matches the electrical
requirements of the vehicle.
To ensure proper operation of the battery
management system (BMS), do not allow
a technician to connect any electrical
device ground connection directly to the
low voltage battery negative post. A
connection at the low voltage battery
negative post can cause inaccurate
measurements of the battery condition
and potential incorrect system operation.
Note:
If a person adds electrical or
electronic accessories or components to the
vehicle, the accessories or components may
adversely affect the low voltage battery
performance and durability and may also
affect the performance of other electrical
systems in the vehicle.
For longer, trouble-free operation, keep the
top of the battery clean and dry. Also,
make certain the battery cables are always
tightly fastened to the battery terminals.
If you see any corrosion on the battery or
terminals, remove the cables from the
terminals and clean with a wire brush. You
can neutralize the acid with a solution of
baking soda and water.
When a battery replacement is required,
the battery should only be replaced with
a Ford recommended replacement battery
that matches the electrical requirements
of the vehicle.
Because your vehicle ’s engine is
electronically-controlled by a computer,
some engine control settings are
maintained by power from the low voltage
battery. Some engine computer settings,
like the idle trim and fuel trim strategy,
optimize the driveability and performance
of the engine. Some other computer
settings, like the clock and radio station
223
C-MAX (CCG) Canada/United States of America, enUSA, Second Printing Maintenance

presets, are also maintained in memory by
power from the low voltage battery. When
a technician disconnects and connects the
low voltage battery, these settings are
erased. Complete the following procedure
in order to restore the settings:
1. With the vehicle at a complete stop,
set the parking brake.
2. Shift into park (P).
3. Switch off all accessories.
4. Fully press the brake pedal and start the vehicle.
5. Run the engine until it reaches normal operating temperature. While the
engine is warming up, complete the
following: Reset the clock. See Audio
System (page 282). Reset the power
windows bounce-back feature. See
Windows and Mirrors
(page 79).
Reset the radio station presets. See
Audio System
(page 282).
6. Allow the engine to idle for at least one
minute. If the engine turns off, press
the accelerator pedal to start the
engine.
7. While the engine is running, press the brake pedal and shift into neutral (N).
8. Allow the engine to run for at least one
minute by pressing on the accelerator
pedal.
9. Drive the vehicle at least 12 mi (20 km)
to completely relearn the idle and fuel
trim strategy.
Note: If you do not allow the engine to
relearn the idle and fuel trim strategy, the
idle quality of your vehicle may be adversely
affected until the engine computer
eventually relearns the idle trim and fuel
trim strategy.
Make sure that you dispose of old batteries
in an environmentally friendly way. Seek
advice from your local authority about
recycling old batteries. CHECKING THE WIPER
BLADES
Run the tip of your fingers over the edge of
the blade to check for roughness.
Clean the wiper blades with washer fluid
or water applied with a soft sponge or
cloth.
CHANGING THE WIPER
BLADES
Note:
Use the service position in winter to
provide easier access to the front wiper
blades for freeing them from snow and ice.
The front wipers will not return to their
normal position as soon as you switch on
the ignition. The front wipers will stay in the
service position when you switch the ignition
on or start the engine. Switch on the front
wipers to any mode, then switch off the
front wipers to bring the front wipers back
to the park position.
Note: The windshield wiper blades are
different in length. If you install wiper blades
of the wrong length, the wipers may not
work correctly. If equipped with autowipers,
the rain sensor may not work correctly.
Note: Make sure that the wiper blade locks
into place. Lower the wiper arm and blade
back to the windshield. The wiper arms will
automatically return to their normal position
when the ignition is turned on.
Note: Replace wiper blades at least once
per year for optimum performance.
