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 426).
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 426).
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

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 266).
• 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.
215
C-MAX (CCG) Mexico/United States of America/Canada, enUSA, CPE Review 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.

We engineer and test all motor vehicles
and their components for reliable, regular
driving. Under various conditions,
long-term storage may lead to degraded
engine performance or failure unless you
use specific precautions to preserve engine
components.
General
•
Store all vehicles in a dry, ventilated
place.
• Protect from sunlight, if possible.
• If vehicles are stored outside, they
require regular maintenance to protect
against rust and damage.
Body
• Wash your vehicle thoroughly to
remove dirt, grease, oil, tar or mud from
exterior surfaces, rear-wheel housing
and the underside of front fenders.
• Periodically wash your vehicle if it is
stored in exposed locations.
• Touch-up exposed or primed metal to
prevent rust.
• Cover chrome and stainless steel parts
with a thick coat of auto wax to prevent
discoloration. Re-wax as necessary
when you wash your vehicle.
• Lubricate all hood, door and trunk lid
hinges, and latches with a light grade
oil.
• Cover interior trim to prevent fading.
• Keep all rubber parts free from oil and
solvents. Engine
•
The engine oil and filter should be
changed prior to storage because used
engine oil contains contaminates that
may cause engine damage.
• Start the engine every 15 days for a
minimum of 15 minutes. Run at fast idle
with the climate controls set to defrost
until the engine reaches normal
operating temperature.
• With your foot on the brake, shift
through all the gears while the engine
is running.
• We recommend that you change the
engine oil before you use your vehicle
again.
Fuel system
• Fill the fuel tank with high-quality fuel
until the first automatic shutoff of the
fuel pump nozzle.
Cooling system
• Protect against freezing temperatures.
• When removing your vehicle from
storage, check coolant fluid level.
Confirm that there are no cooling
system leaks and that fluid is at the
recommended level.
Battery
• Check and recharge as necessary. Keep
connections clean.
• If storing your vehicle for more than 30
days without recharging the battery,
we recommend that you disconnect
the battery cables to maintain battery
charge for quick starting.
Note: It is necessary to reset memory
features if battery cables are disconnected.

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, a qualified expert, such
as the factory-trained technicians at your
dealership, should inspect discolored fluids
that also show signs of overheating or
foreign material contamination
immediately.
Make sure to change your vehicle
’s oils and
fluids 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.
Owner Checks and Services
Make sure you perform the following basic
maintenance checks and inspections every
month or at six-month intervals. Check every month
Engine oil level.
Function of all interior and exterior lights.
Tires (including spare) for wear and proper pressure. Windshield washer fluid level. Check every six months
Battery connections. Clean if necessary.
Body and door drain holes for obstructions. Clean if necessary. Cooling system fluid level and coolant strength.
Door weatherstrips for wear. Lubricate if necessary.
Hinges, latches and outside locks for proper operation. Lubricate if necessary. Parking brake for proper operation.
Safety belts and seat latches for wear and function.
Safety warning lamps (brake, ABS, airbag and safety belt) for operation.
Washer spray and wiper operation. Clean or replace blades as necessary.
