1.
Fill the fuel tank completely and record
the initial odometer reading.
2. Each time you fill the tank, record the amount of fuel added.
3. After at least three to five tank fill ups, fill the fuel tank and record the current
odometer reading.
4. Subtract your initial odometer reading from the current odometer reading.
5. Calculate fuel economy by dividing miles traveled by gallons used (For
Metric: Multiply liters used by 100, then
divide by kilometers traveled).
Keep a record for at least one month and
record the type of driving (city or highway).
This provides an accurate estimate of the
vehicle ’s fuel economy under current
driving conditions. Additionally, keeping
records during summer and winter show
how temperature impacts fuel economy.
In general, lower temperatures mean lower
fuel economy.
EMISSION CONTROL SYSTEM WARNINGS
Do not park, idle, or drive your vehicle
in dry grass or other dry ground cover.
The emission system heats up the
engine compartment and exhaust system,
which can start a fire. Exhaust leaks may result in entry of
harmful and potentially lethal fumes
into the passenger compartment. If
you smell exhaust fumes inside your
vehicle, have your dealer inspect your
vehicle immediately. Do not drive if you
smell exhaust fumes. Your vehicle is equipped with various
emission control components and a
catalytic converter that 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:
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 in scheduled
maintenance information performed
according to the specified schedule.
The scheduled maintenance items listed
in scheduled maintenance information are
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 details.
On-Board Diagnostics (OBD-II)
Your vehicle is equipped with a computer
that monitors the engine ’s emission control
system. This system is commonly known
as the on-board diagnostics system
(OBD-II). The OBD-II system protects the
environment by ensuring that your vehicle
continues to meet government emission
standards. The OBD-II system also assists
your authorized dealer in properly servicing
your vehicle. When the service engine soon
indicator illuminates, the OBD-II
system has detected a
malfunction. Temporary malfunctions may
cause the service engine soon indicator to
illuminate. Examples are:
1. The vehicle has run out of fuel —the
engine may misfire or run poorly.
2. Poor fuel quality or water in the fuel —the engine may misfire or run
poorly.
3. The fuel fill inlet may not have been properly closed. See Refueling (page
138).
4. Driving through deep water —the
electrical system may be wet. These temporary malfunctions can be
corrected by filling the fuel tank with good
quality fuel, properly closing the fuel fill
inlet or letting the electrical system dry out.
After three driving cycles without these or
any other temporary malfunctions present,
the service engine soon indicator should
stay off the next time the engine is started.
A driving cycle consists of a cold engine
startup followed by mixed city/highway
driving. No additional vehicle service is
required.
If the service engine soon indicator remains
on, have your vehicle serviced at the first
available opportunity. Although some
malfunctions detected by the OBD-II may
not have symptoms that are apparent,
continued driving with the service engine
soon indicator on can result in increased
emissions, lower fuel economy, reduced
engine and transmission smoothness, and
lead to more costly repairs.
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. See On-Board Diagnostics.
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.
144
C-MAX (CCG) Fuel and Refueling

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/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 with the ignition Off. Then, start the
vehicle and complete the above driving
cycle. The vehicle must warm up to its
normal operating temperature. Once
started, do not turn off the vehicle 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.

Note:
Your electrical source must meet
certain requirements for the high-voltage
batteries to charge. The AC outlet must be
a three-prong 110-120 volt AC outlet that is
properly grounded, 15– 20 amps (or greater),
and in good condition. You must use a
dedicated line, which means you cannot
have other appliances connected to the
same circuit. If you do not use a dedicated
circuit, the circuit breaker could trip or open.
If you do not have a dedicated circuit,
contact a licensed professional electrician
for proper installation.
Make sure that the 120– volt convenience
cord is completely unwound before

lights up when you plug the cord into the
AC wall outlet.
Charge (green light) —
indicates status
of charging:
• No light means you have not connected
the cord to the vehicle.
• Blinking light means that the charging
is in process.
• Solid light means you have connected
the cord, but the vehicle is not charging.
Fault (red triangle light) —
Lights up in
case of a detected failure. No charging is
possible:
• Blinking red triangle light – means that
the 120– volt convenience cord is trying
to reset the failure and could restart
the charging cycle.
• Solid red triangle light – means that
the fault is permanent. You need to
unplug the cord and then plug it back
in to reset the fault. If the fault persists,
