Your cabin air filter is located under the instrument panel in the
passenger footwell area. The particulate filtration system reduces the
concentration of airborne particles such as dust, spores and pollen in
the air supplied to the interior of your vehicle. The particulate filtration
system gives you and your passengers the following benefits:
•It improves your driving comfort by reducing particle concentration.
•It improves the interior compartment cleanliness.
•It protects the climate control components from particle deposits.
Replace the filter at regular intervals. See theScheduled Maintenance
chapter.
For more information about your filter, see an authorized dealer.

section of the Settings menu.
Frequently Asked Questions
Question Answer
What are the
series of clicks
from the cargo
area when I first
turn the key in
the ignition?The high voltage battery is electrically isolated from
the rest of the vehicle when the key is off. When
the key is turned to on, high voltage contactors
inside the battery are closed to make the electricity
available to the motor/generator and enable the
vehicle to drive. The clicks are the sound of these
contactors as they close and open during start up
and shut down.
Why does the
engine sometimes
start at key-on?The vehicle’s computer will determine if an engine
start is required at key-on. Silent key start will start
the engine if it is necessary for cabin heating,
windshield defrost, or if the outside temperature is
low. (For C-MAX Energi vehicles, engine on is not
required to operate these functions.)

Question Answer
What is the fan
noise I hear from
the rear of my
hybrid?The fan noise comes from a fan located inside the
high voltage battery. This fan turns on when the
battery requires cooling air. The fan speed, and
associated noise level, will change according to
the amount 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
engine oil change
service interval?The engine oil should be changed every 10000 miles
(16000 km) under normal operating conditions. See
theScheduled maintenance information.
Can I put E15 or
E85 in my
vehicle, and how
will it affect my
fuel economy?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).
How long will my
high voltage
battery last?
Does it need
maintenance?The high voltage battery system is designed to last
the life of the vehicle and requires no maintenance.
Can you charge
the battery with
aplugintoan
A/C outlet?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 I tow the
hybrid behind my
motor home with
all four wheels
down?Yes. Your hybrid vehicle can be flat-towed without
modification. See theRecreational towingsection
in theTowingchapter for more information.

Your vehicle is equipped with various emission control components
and a catalytic converter which will enable your vehicle to comply with
applicable exhaust emission standards. To make sure that the catalytic
converter and other emission control components continue to work
properly:
•Use only the specified fuel listed.
•Avoid running out of fuel.
•Do not turn off the ignition while your vehicle is moving, especially at
high speeds.
•Have the items listed inScheduled Maintenance Information
performed according to the specified schedule.
The scheduled maintenance items listed inScheduled Maintenance
Informationare essential to the life and performance of your vehicle
and to its emissions system.
If other than Ford, Motorcraft® or Ford-authorized parts are used for
maintenance replacements or for service of components affecting
emission control, such non-Ford parts should be equivalent to genuine
Ford Motor Company parts in performance and durability.
Illumination of the service engine soon indicator, charging system
warning light or the temperature warning light, fluid leaks, strange odors,
smoke or loss of engine power could indicate that the emission control
system is not working properly.
An improperly operating or damaged exhaust system may allow exhaust
to enter the vehicle. Have a damaged or improperly operating exhaust
system inspected and repaired immediately.
Do not make any unauthorized changes to your vehicle or engine.
By law, vehicle owners and anyone who manufactures, repairs, services,
sells, leases, trades vehicles, or supervises a fleet of vehicles are not
permitted to intentionally remove an emission control device or prevent
it from working. Information about your vehicle’s emission system is on
the Vehicle Emission Control Information Decal located on or near the
engine. This decal also lists engine displacement.
Please consult your warranty information for complete emission warranty
information.

Readiness for Inspection/Maintenance (I/M) Testing
Some state, provincial and local governments may have
Inspection/Maintenance (I/M) programs to inspect the emission control
equipment on your vehicle. Failure to pass this inspection could prevent
you from getting a vehicle registration.
If the service engine soon indicator is on or the bulb does not
work, the vehicle may need to be serviced. SeeOn-board
Diagnostics (OBD-II)in this chapter.
Your vehicle may not pass the I/M test if the service engine soon
indicator is on or not working properly (bulb is burned out), or if the
OBD-II system has determined that some of the emission control systems
have not been properly checked. In this case, the vehicle is considered
not ready for I/M testing.
If the vehicle’s engine or transmission has just been serviced, or the
battery has recently run down or been replaced, the OBD-II system may
indicate that the vehicle is not ready for I/M testing. To determine if the
vehicle is ready for I/M testing, turn the ignition key to the on position
for 15 seconds without cranking the engine. If the service engine soon
indicator blinks eight times, it means that the vehicle is not ready for I/M
testing; if the service engine soon indicator stays on solid, it means that
the vehicle is ready for I/M testing.
The OBD-II system is designed to check the emission control system
during normal driving. A complete check may take several days. If the
vehicle is not ready for I/M testing, the following driving cycle consisting
of mixed city and highway driving may be performed:
15 minutes of steady driving on an expressway or highway followed by
20 minutes of stop-and-go driving with at least four 30-second idle
periods.
Allow the vehicle to sit for at least eight hours without starting the
engine. Then, start the engine and complete the above driving cycle.
The engine must warm up to its normal operating temperature. Once the
engine is started, do not turn off the engine until the above driving cycle
is complete. If the vehicle is still not ready for I/M testing, the above
driving cycle will have to be repeated.
