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.

HINTS ON CONTROLLING THE
INTERIOR CLIMATE
General Hints
Note: Prolonged use of recirculated air may
cause the windows to fog up.
Note: You may feel a small amount of air
from the footwell air vents regardless of the
air distribution 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: Do not adjust the settings when your
vehicle interior is extremely hot or cold. The
system automatically adjusts to the
previously stored settings. For the system
to function efficiently, the instrument panel
and side air vents should be fully open.
Note: At low ambient temperatures with
AUTO selected, the system directs the air
stream toward the windshield and side
windows for as long as the engine remains
cold.
Note: When you switch off the system,
outside air does not enter your vehicle. Note:
When the system is in AUTO mode,
and the interior and exterior temperatures
are high, the system automatically selects
recirculated air to maximize cooling of the
interior. When the interior reaches the
selected temperature, the system
automatically selects outside air.
Note: When you select windshield
defrosting and defogging, the instrument
panel and footwell level functions switch
off automatically and air conditioning
switches on. Outside air flows into your
vehicle.
For maximum cooling performance, press
MAX A/C
.
To aid in side window defogging and
demisting in cold weather, press the floor
vent button.
In mild weather, you can improve your fuel
economy when using the climate control
system by using outside air instead of air
conditioning.
• Turn the temperature control knob(s)
so the interior temperature is set to
60°F (15.5°C).
• Set the air distribution to panel or floor
(or both).
• Press
A/C so that A/C OFF appears
in the display.
• Press the recirculated air button so
fresh air enters the vehicle.
• Press the small fan button until the fan
is at its lowest setting.

C-MAX (CCG) Climate Control

•
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 position 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 position
N.
Low Gear:
Low gear (position 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 position
D.
Reverse:
In position 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 ensures
battery life and provides the best possible
performance. Your hybrid high voltage
battery may periodically re-condition itself
to ensure 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 tachometer 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.

C-MAX (CCG) Unique Driving Characteristics

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 during
steady state driving. These are character-
istics of the Atkinson engine cycle and the transmission technology that help
maximize 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
182).
Can I tow the hybrid behind my motor home
with all four wheels down?

HAZARD WARNING FLASHERS
Note:
If used when the vehicle is not
running, the battery will lose charge. There
may be insufficient power to restart your
vehicle. The hazard warning button is
located on the instrument panel.
Use it when your vehicle is
creating a safety hazard for other
motorists.
• Press the button to turn on the hazard
warning function, and the front and
rear direction indicators will flash.
• Press the button again to turn them
off.
FUEL SHUTOFF WARNING
Failure to inspect and, if necessary,
repair fuel leaks after a collision may
increase the risk of fire and serious
injury. Ford Motor Company recommends
that the fuel system be inspected by an
authorized dealer after any collision. In the event of a moderate to severe
collision, this vehicle is equipped with a
fuel pump shut-off feature that stops the
flow of fuel to the engine. Not every impact
will cause a shut-off.
Should your vehicle shut off after a
collision, you may restart your vehicle by
doing the following:
1. Turn the ignition off.
2. Turn the ignition to crank.
3. Turn the ignition off.
4.
Turn the ignition on again to re-enable
the fuel pump.
For vehicles equipped with a push button
start system: 1. Press the START/STOP button to
turn the ignition off.
2. Press the brake pedal and press the START/STOP
button (crank
attempt).
3. Remove your foot from the brake pedal
and press the
START/STOP button
(ignition off).
4. Press the
START/STOP button again
to re-enable the fuel system.
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.

ENGINE COOLANT CHECK
Engine Coolant and Inverter
System Controller Coolant
Your vehicle is equipped with 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 417).
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. The coolant concentration should be
maintained 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 Rotunda tool
300-ROB75240 available from your dealer.
Ford does 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 417).
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.
The coolant concentration should be
maintained within 48% to 50%, which
equates to a freeze point between -30°F
(-34°C) and -34°F (-37°C).

C-MAX (CCG) Maintenance

Note:
For best results, coolant
concentration should be tested with a
refractometer such as Rotunda tool
300-ROB75240 available from your dealer.
Ford does 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 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.
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 265).
• 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
only 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.
