2015 FORD C MAX maintenance reset

During certain events (such as vehicle
servicing) your low voltage 12-volt battery
may become disconnected or disabled.
Once the battery is reconnected and after
driving the vehicle, the engine may
continue to operate for three to five
seconds after the key is turned to off. This
is a normal condition.
Braking: Your hybrid is equipped with
standard hydraulic braking and
regenerative braking. Regenerative braking
is performed by your transmission and it
captures brake energy and stores it in your
high voltage battery.
Driving to Optimize Fuel Economy
Note: Having your engine running is not
always an indication of inefficiency. In some
cases, it is actually more efficient than
driving in electric mode.
Your fuel economy should improve
throughout your hybrid's break-in period.
As with any vehicle, your driving habits and
accessory usage can significantly impact
your fuel economy. For best results, keep
in mind these tips:
• Keep the tires properly inflated and
only use the recommended size.
• Aggressive driving increases the
amount of energy required to move
your vehicle. In general, you can
achieve better fuel economy with mild
to moderate acceleration and
deceleration. Moderate braking is
particularly important since it allows
you to maximize the energy captured
by the regenerative braking system.
Additional Tips:
• Do not carry extra loads.
• Be mindful of adding external
accessories that may increase
aerodynamic drag.
• Observe posted speed limits. •
Perform all scheduled maintenance.
• There is no need to wait for your engine
to warm up. The vehicle is ready to
drive immediately after starting.
EV+ Mode (C-MAX Energi Only)
Your vehicle will recognize your frequent
destinations and allow for more EV driving
as you approach them. For example, when
nearing your home it should be easier to
stay in electric mode. The EV indicator will
display EV+ when this mode is active. You
should see this approximately 1/8 mile
(200 meters) from a frequent destination.
See
Information Displays (page 91).
Note: Frequent destinations are learned by
your vehicle after two to four weeks of use.
You can clear these destinations with a
Driving History reset through the Settings
menu.
Note: You can switch the EV+ feature on
or off through the Driver Assist section of
the Settings menu.
Low Engine Use (If Equipped)
The low engine use mode is equipped on
Energi models only. The low engine use
mode will activate automatically when you
drive your vehicle with limited engine use.
The mode will maintain proper engine
lubrication at sufficient temperature. If your
vehicle is in low engine use mode when you
start the vehicle, a message will appear in
the information display. When your vehicle
is in low engine use mode, your vehicle will
automatically run the engine as necessary.
If you select the EV Now mode while the
vehicle is in the low engine use mode, EV
Now mode will be suspended for as long
as you are in low engine use mode The low
engine use mode will resume the next time
you start your vehicle and will
automatically stop when no longer needed.

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.
218
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.

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.
