AUTOMATIC CLIMATE CONTROL
AUTO: Press the button to switch on automatic operation. Select the desired
temperature using the temperature control. The system adjusts fan speed, air
distribution, air conditioning operation, and selects outside air or recirculated
air to heat or cool the vehicle in order to maintain the desired temperature.
A
Fan speed control:
Adjust the volume of air circulated in the vehicle.
B
Power:
Press the button to switch the system on and off. When the system is
off, it prevents outside air from entering the vehicle.
C
MAX Defrost: Press the button to switch on defrost. Outside air flows through
the windshield vents, air conditioning automatically turns on, and fan
automatically adjusts to the highest speed. You can also use this setting to
defrost and clear the windshield of a thin covering of ice. The heated rear window
also automatically turns on when you select maximum defrost.
D
Note:
To prevent window fogging, you cannot select recirculated air when
maximum defrost is on.
MAX A/C:
Press the button to maximize cooling. Recirculated air flows through
the instrument panel vents, air conditioning automatically turns on, and the fan
automatically adjusts to the highest speed.
E
Recirculated air:
Press the button to switch between outside air and
recirculated air. When you select recirculated air, the air currently in the
passenger compartment recirculates. This may reduce the time needed to cool
the interior (when used with
A/C) and may reduce unwanted odors from
entering your vehicle.

Note: In certain conditions (for example, maximum defrost), the air conditioning
compressor may continue to operate even though the air conditioning is
switched off.
Temperature Control You can set the temperature between
60°F (15.5°C) and 85°F (29.5°C) in steps
of 1°F (0.5°C). In position LO, 59°F (15°C),
the system switches to permanent cooling.
In position
HI, 86°F (30°C), the system
switches to permanent heating.
Single Zone Temperature Control
In this mode, the climate control system
links the temperature settings for both the
driver's side and passenger's side. If you
adjust the setting using the rotary control
on the driver ’s side, the system adjusts the
temperature to the same setting on the
passenger ’s side. Dual Zone Temperature Control
Select a temperature for the passenger
’s
side using the rotary control on the
passenger ’s side. Single zone temperature
control automatically switches off. The
temperature on the driver ’s side remains
unchanged. You can now adjust the
driver's side and passenger's side
temperatures independently. The display
shows the temperature settings for each
side.
Switching Back to Single Zone
Temperature Control
Press and hold the
AUTO button. The
passenger side temperature is adjusted to
the driver side temperature setting.

Note:
To reduce humidity build-up inside
your vehicle, do not drive with the system
switched off or with recirculated air always
switched on.
Note: Do not place objects under the front
seats as this may interfere with the airflow
to the rear seats.
Note: Remove any snow, ice or leaves from
the air intake area at the base of the
windshield.
Note: To improve the time to reach comfort
in hot weather, drive with the windows
slightly open for 2-3 minutes after start-up
or until your vehicle airs out.
In mild weather, you can improve your fuel
economy when using the climate control
system by using outside air instead of air
conditioning.

•
Very high or low outside temperature
(to provide system cooling or heating).
For C-MAX Energi vehicles, climate
control demands by passengers may
not directly cause the engine to run.
This only occurs when the high voltage
battery charge is low, or if the outside
temperature is cold enough to require
the engine to provide additional heat
for the cabin.
• Engine not warm enough to provide
passenger requested cabin
temperature.
Stopping: The gas engine may shut off
to conserve fuel as you come to a stop.
Restarting the vehicle is not required.
Simply step on the accelerator when you
are ready to drive.
Transmission Operation:
Due to the
technologically advanced,
electronically-controlled continuously
variable transaxle, you will not feel shift
changes like those of a non-hybrid vehicle.
Note: Since engine speed is controlled by
the transmission, it may seem elevated at
times. This is normal hybrid operation and
helps deliver fuel efficiency and
performance.
Neutral:
It is not recommended to idle the
vehicle in neutral (N) for an extended
period of time because this will discharge
your high voltage battery and decrease fuel
economy. The engine will not start or stop,
and cannot provide power to the hybrid
system in neutral (N).
Low:
Low (L) is designed to mimic the
enhanced engine braking available in
non-hybrid vehicles. Low gear will produce
high engine speeds to provide necessary
engine braking. This is normal and will not
damage your vehicle. In low gear, the gas
engine will remain on more often than in
drive (D).
Reverse:
In reverse (R), vehicle speed is
limited to 22 mph (35 km/h). Unique Hybrid Operating
Characteristics
Your vehicle behaves differently compared
to a non-hybrid. Here is a description of the
major differences:
Battery:
Your hybrid is equipped with a
high voltage battery. A cool battery
maintains battery life and provides the
best possible performance. Your hybrid
high voltage battery may periodically
re-condition itself to maintain maximum
efficiency. You may notice slight changes
in driveability during this process, but it is
an important part of your hybrid's high
voltage battery optimization features.
The high voltage battery is cooled by cabin
air drawn from vent holes in the trim panels
behind the rear seats. Avoid placing objects
at the vent holes that block airflow to the
high voltage battery.
Engine:
The engine speed in your hybrid
is not directly tied to your vehicle speed.
Your vehicle's engine and transmission are
designed to deliver the power you need at
the most efficient engine speed. During
heavy accelerations, your hybrid may reach
high engine speeds (up to 6000 RPM).
In prolonged mountainous driving, you may
see the engine speed changing without
your input. This is intentional and maintains
the battery charge level. You may also
notice during extended downhill driving
that your engine continues to run instead
of shutting off.
During this engine braking, the engine stays
on, but it is not using any fuel. You may also
hear a slight whine or whistle when
operating your vehicle. This is the normal
operation of the electric generator in the
hybrid system.

Answer
Question
Your vehicle's engine and transmission aredesigned to deliver the power you need atthe most efficient engine speed. This may be higher than expected during heavy
accelerations, and may fluctuate when
driving at a steady speed. These are charac- teristics of the Atkinson engine cycle and the transmission technology that helpmaximize your hybrid's fuel economy.
Why does my engine rev up so high some-
times when I accelerate?
The fan noise comes from a fan located
next to the high voltage battery pack. This fan turns on when the battery requires
cooling air. The fan speed, and associated noise level, will change according to theamount of cooling required to maintain
good performance. Maintaining the battery temperature at optimal conditions also
prolongs the useful life of the battery and helps to achieve better fuel economy.
What is the fan noise I hear from the rear
of my hybrid?
Change the engine oil every 10000 miles
(16000 kilometers) or once per year under normal operating conditions.
What is the engine oil change service
interval?
Your hybrid vehicle can use E15 (15%
ethanol, 85% gasoline) fuel, but you may notice slightly reduced fuel economy
because ethanol contains less energy per
gallon than gasoline. Your hybrid vehicle is not designed to use E85 (85% ethanol).
Can I put E15 or E85 in my vehicle, and how
will it affect my fuel economy?
The high voltage battery system is designedto last the life of the vehicle and requires no maintenance.
How long will my high voltage battery last?
Does it need maintenance?
There are no provisions for charging the
high voltage battery from a power supply
external to the vehicle. (For C-MAX Energi
vehicles, the vehicle can be plugged into a
110-volt outlet with charge cord provided.)
Can you charge the battery with a plug into
an A/C outlet?
Yes. Your hybrid vehicle can be flat towed
without modification. See Towing (page
186).
Can I tow the hybrid behind my motor home
with all four wheels down?

2. Press the brake pedal and press the
push button start to switch on the
ignition.
3. Check the information display for the Ready to Drive light as the gasoline
engine may not start, but the electric
motor may be running. If you do not see
the Ready to Drive light, repeat Steps
1 and 2 up to two more times.
Note: When you try to restart your vehicle
after a fuel shutoff, the vehicle makes sure
that the electrical system is safe to restart.
Once your vehicle determines that the
electrical system is safe, then the vehicle
will allow you to restart.
Note: In the event that your vehicle does
not restart after your third attempt, contact
an authorized dealer.
JUMP STARTING THE VEHICLE WARNINGS
The gases around the battery can
explode if exposed to flames, sparks
or lit cigarettes. An explosion could
result in injury or vehicle damage. Batteries contain sulfuric acid which
can burn skin, eyes and clothing, if
contacted. Do not attempt to push-start your
automatic transmission vehicle. Automatic
transmissions do not have push-start
capability. Attempting to push-start a
vehicle with an automatic transmission
may cause transmission damage.
Preparing Your Vehicle
Note:
Use only a 12-volt supply to start your
vehicle.
Note: Do not disconnect the battery of the
disabled vehicle as this could damage the
vehicle's electrical system.
1. Park the booster vehicle close to the hood of the disabled vehicle making
sure the two vehicles do not touch. Set
the parking brake on both vehicles and
stay clear of the engine cooling fan and
other moving parts.
2. Check all battery terminals and remove
any excessive corrosion before you
attach the battery cables. Ensure that
vent caps are tight and level.
3. Turn the heater fan on in both vehicles
to protect from any electrical surges.
Turn all other accessories off.
Connecting the Jumper Cables
Your vehicle has a 12-volt battery that has
two prongs accessible from under the
hood. Your vehicle can be jumped the
same way conventional vehicles can by
using these prongs. The illustration below
shows the two connector prongs used for
jump-starting your vehicle.

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.

C-MAX (CCG) Canada/United States of America, enUSA, Second Printing Maintenance

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.
