2018 FORD C-MAY HYBRID brake

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).

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.

BRAKE FLUID CHECK
WARNINGS
Do not use any fluid other than the
recommended brake fluid as this will
reduce brake efficiency. Use of
incorrect fluid could result in the loss of
vehicle control, serious personal injury or
death. Only use brake fluid from a sealed
container. Contamination with dirt,
water, petroleum products or other
materials may result in brake system
damage or failure. Failure to adhere to this
warning could result in the loss of vehicle
control, serious personal injury or death. Do not allow the fluid to touch your
skin or eyes. If this happens, rinse the
affected areas immediately with
plenty of water and contact your physician. A fluid level between the MAX and
MIN lines is within the normal
operating range and there is no need
to add fluid. A fluid level not in the normal
operating range could compromise the
performance of the system. Have your
vehicle checked immediately. To avoid fluid contamination, the reservoir
cap must remain in place and fully tight,
unless you are adding fluid.
Only use fluid that meets Ford
specifications. See
Capacities and
Specifications (page 270).
POWER STEERING FLUID
CHECK
Your vehicle is equipped with an electric
power steering (EPS) system. There is no
fluid reservoir to check or fill. WASHER FLUID CHECK WARNING
If you operate your vehicle in
temperatures below
41.0°F (5°C),
use washer fluid with antifreeze
protection. Failure to use washer fluid with
antifreeze protection in cold weather could
result in impaired windshield vision and
increase the risk of injury or accident. Note:
The front and rear washer systems
are supplied from the same reservoir.
Add fluid to fill the reservoir if the level is
low. Only use a washer fluid that meets
Ford specifications. See
Capacities and
Specifications (page 270).
State or local regulations on volatile
organic compounds may restrict the use
of methanol, a common windshield washer
antifreeze additive. Washer fluids
containing non-methanol antifreeze
agents should be used only if they provide
cold weather protection without damaging
the vehicle ’s paint finish, wiper blades or
washer system.
FUEL FILTER
Your vehicle is equipped with a lifetime
fuel filter that is integrated with the fuel
tank. Regular maintenance or replacement
is not needed.

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
Replace the wiper blades at least annually
for optimum performance.
You can improve poor wiper quality by
cleaning the wiper blades and the
windshield.
Note:
The windshield wiper blades are
different in length. If you install wiper
blades of the wrong length, the wiper blades
can clash damaging the wiper system.
Service Position
Set the windshield wipers in the service
position to change the wiper blades.
Note: You can use the service position to
provide easier access to the wiper blades
for freeing them from snow and ice.
