Low Engine Use
The low engine use mode is equipped on
Energi models only. The Low Engine Use
mode maintains proper engine lubrication
at sufficient temperature, and will activate
automatically when you drive your vehicle
with limited engine operation. When your
vehicle is in low engine use mode, your
vehicle will automatically run the engine
as necessary.
Note: If your vehicle is in low engine use
mode when you start your vehicle, a
message will appear in the information
display. See General Information (page
92).
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

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
192).
Can I tow the hybrid behind my motor home
with all four wheels down?

SAFETY PRECAUTIONS
WARNINGS
Do not overfill the fuel tank. The
pressure in an overfilled tank may
cause leakage and lead to fuel spray
and fire. The fuel system may be under
pressure. If you hear a hissing sound
near the fuel filler inlet, do not refuel
until the sound stops. Otherwise, fuel may
spray out, which could cause serious
personal injury. Fuels can cause serious injury or
death if misused or mishandled.
Flow of fuel through a fuel pump
nozzle can produce static electricity.
This can cause a fire if you are filling
an ungrounded fuel container. Fuel may contain benzene, which is
a cancer-causing agent.
When refueling always shut the
engine off and never allow sparks or
open flames near the fuel tank filler
valve. Never smoke or use a cell phone
while refueling. Fuel vapor is extremely
hazardous under certain conditions. Avoid
inhaling excess fumes. Observe the following guidelines when
handling automotive fuel:
•
Extinguish all smoking materials and
any open flames before refueling your
vehicle.
• Always turn off the vehicle before
refueling. •
Automotive fuels can be harmful or
fatal if swallowed. Fuel such as
gasoline is highly toxic and if
swallowed can cause death or
permanent injury. If fuel is swallowed,
call a physician immediately, even if no
symptoms are immediately apparent.
The toxic effects of fuel may not be
visible for hours.
• Avoid inhaling fuel vapors. Inhaling too
much fuel vapor of any kind can lead
to eye and respiratory tract irritation.
In severe cases, excessive or prolonged
breathing of fuel vapor can cause
serious illness and permanent injury.
• Avoid getting fuel liquid in your eyes. If
fuel is splashed in the eyes, remove
contact lenses (if worn), flush with
water for 15 minutes and seek medical
attention. Failure to seek proper
medical attention could lead to
permanent injury.
• Fuels can also be harmful if absorbed
through the skin. If fuel is splashed on
the skin, clothing or both, promptly
remove contaminated clothing and
wash skin thoroughly with soap and
water. Repeated or prolonged skin
contact with fuel liquid or vapor causes
skin irritation.
• Be particularly careful if you are taking
Antabuse or other forms of Disulfiram
for the treatment of alcoholism.
Breathing gasoline vapors could cause
an adverse reaction, serious personal
injury or sickness. If fuel is splashed on
the skin, wash the affected areas
immediately with plenty of soap and
water. Consult a physician immediately
if you experience any adverse reactions.

FUEL QUALITY
Choosing the Right Fuel
Your vehicle is designed to operate on
regular unleaded gasoline with a minimum
pump (R+M)/2 octane rating of 87.
Some fuel stations, particularly those in
high altitude areas, offer fuels posted as
regular unleaded gasoline with an octane
rating below 87. We do not recommend
these fuels.
For best overall vehicle and engine
performance, premium fuel with an octane
rating of 91 or higher is recommended. The
performance gained by using premium fuel
is most noticeable in hot weather.
Do not use any fuel other than those
recommended because they could lead to
engine damage that will not be covered by
the vehicle Warranty.
Note:
Use of any fuel other than those
recommended can impair the emission
control system and cause a loss of vehicle
performance.
Do not use:
• Diesel fuel.
• Fuels containing kerosene or paraffin.
• Fuel containing more than 15% ethanol
or E85 fuel.
• Fuels containing methanol.
• Fuels containing metallic-based
additives, including manganese-based
compounds. •
Fuels containing the octane booster
additive, methylcyclopentadienyl
manganese tricarbonyl (MMT).
• Leaded fuel (using leaded fuel is
prohibited by law).
The use of fuels with metallic compounds
such as methylcyclopentadienyl
manganese tricarbonyl (commonly known
as MMT), which is a manganese-based
fuel additive, will impair engine
performance and affect the emission
control system.
Do not be concerned if the engine
sometimes knocks lightly. However, if the
engine knocks heavily while using fuel with
the recommended octane rating, contact
an authorized dealer to prevent any engine
damage.
Fuel Freshness Mode (If Equipped)
This helps keep the fuel system functional
and the fuel fresh.
If you mainly use your vehicle in electric
power mode without refueling, the gasoline
in the fuel tank may become stale due to
aging. Stale gasoline can damage the
engine and fuel system.
Your vehicle automatically switches to fuel
freshness mode if you do not refuel your
vehicle with fresh fuel within an 18-month
period. Fuel freshness mode protects your
vehicle from potential engine and fuel
system damage caused by using stale fuel.
Note: If you do not add new fuel during an
18-month period, fuel freshness mode will
use fuel until approximately
1.2 gal (4.5 L)
of fuel remains in the fuel tank.
143
C-MAX Energi / C-MAX Hybrid (CCG) Canada/United States of America, enUSA, First Printing Fuel and RefuelingE161513

During fuel freshness mode:
•
The information display will indicate
fuel freshness mode is active.
• The vehicle will only run in hybrid mode.
EV Now mode will not be available.
• Most of the plug-in power will be
stored until fuel freshness mode is
completed.
Note: EV Now mode resumes when less
than 1.2 gal (4.5 L) of fuel remains in the fuel
tank.
Note: When the fuel level is less than
one-quarter full, refueling your vehicle will
end fuel freshness mode.
Note: We recommend you use a fuel
stabilizer if you use less than a full tank of
fuel during an 18-month period.
FUEL FILLER FUNNEL
LOCATION
The fuel filler funnel is under the luggage
compartment floor covering.
RUNNING OUT OF FUEL
Running out of fuel can cause damage not
covered by the vehicle Warranty.
If your vehicle runs out of fuel:
• Add a minimum of
1.3 gal (5 L) of fuel
to restart the engine. If your vehicle is
out of fuel and on a steep slope, more
fuel may be required.
• You may need to switch the ignition
from off to on several times after
refueling to allow the fuel system to
pump the fuel from the tank to the
engine. When restarting, cranking time
takes a few seconds longer than
normal. Filling a Portable Fuel Container
Use the following guidelines to avoid
electrostatic charge build-up, which can
produce a spark, when filling an
ungrounded fuel container:
•
Only use an approved fuel container to
transfer fuel to your vehicle. Place the
container on the ground when filling it.
• Do not fill a fuel container when it is
inside your vehicle (including the cargo
area).
• Keep the fuel pump nozzle in contact
with the fuel container when filling it.
• Do not use a device that holds the fuel
pump nozzle lever in the fill position.
Adding Fuel From a Portable Fuel
Container WARNINGS
Do not insert the nozzle of a fuel
container or an aftermarket funnel
into the fuel system filler neck. This
may damage the fuel system filler neck or
its seal and cause fuel to run onto the
ground. Do not try to pry open or push open
the capless fuel system with foreign
objects. This could damage the fuel
system and its seal and cause injury to you
or others. Do not dispose of fuel in the
household refuse or the public
sewage system. Use an authorized
waste disposal facility. When refueling the vehicle fuel tank from
a fuel container, use the fuel filler funnel
included with your vehicle. See Fuel Filler
Funnel Location
(page 144).
Note: Do not use aftermarket funnels as
they will not work with the capless fuel
system and can damage it.

leave the fuel pump unattended
when refueling your vehicle.
Keep children away from the fuel
pump. Never let children pump fuel.
Wait at least 10 seconds before
removing the fuel pump nozzle to
allow any residual fuel to drain into
the fuel tank. Stop refueling after the fuel pump
nozzle automatically shuts off for the
second time. Failure to follow this
will fill the expansion space in the fuel tank
and could lead to fuel overflowing. Do not remove the fuel pump nozzle
from its fully inserted position when
refueling.
The fuel system may be under
pressure. If you hear a hissing sound
near the fuel filler inlet, do not refuel
until the sound stops. Otherwise, fuel may
spray out, which could cause serious
