Answer
Question
The high voltage battery system is designed to last the life of thevehicle 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. SeeTowing (page 254).
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. WARNINGS
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 We recommend regular unleaded gasoline
with a minimum pump (R+M)/2 octane rating
of 87. Some fuel stations offer fuels posted
as regular unleaded gasoline with an octane
rating below 87, particularly in high altitude
areas. We do not recommend fuels with an
octane rating below 87.
Do not use any fuel other than those
recommended because they could lead to
engine damage that may 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. 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.
RUNNING OUT OF FUEL
Avoid running out of fuel because this
situation may have an adverse effect on
vehicle components.
If you have run out of fuel: •
To start the vehicle with a keyless
ignition, just start the engine. Crank time
will be longer than usual.
• Normally, adding 1 gallon (3.8 liters) of
fuel is enough to restart the vehicle. If the
vehicle is out of fuel and on a steep
grade, more than 1 gallon (3.8 liters) may
be required.
• The service engine soon indicator may
come on.
Refilling With a Portable Fuel Container WARNINGS
Do not insert the nozzle of portable
fuel containers or aftermarket funnels
into the capless fuel system. This could
damage the fuel system and its seal, and
may cause fuel to run onto the ground
instead of filling the tank, which could result
in serious personal injury. 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. 177

Note:
Do not use aftermarket funnels; they
will not work with the capless fuel system
and can damage it. The included funnel has
been specially designed to work safely with
your vehicle. When filling the vehicle
’s fuel tank from a
portable fuel container, use the funnel
included with the vehicle.

The funnel is located in the rear of the
vehicle, inside the load compartment,
underneath the load floor carpet and is
accessible from the trunk.
1. Locate the portable funnel that comes
with your vehicle. 2. Slowly insert the funnel into the capless
fuel system. 3.
Fill the vehicle with fuel from the portable
fuel container.
4. When done, clean the funnel or properly
dispose of it. Extra funnels can be
purchased from your authorized dealer
if you choose to dispose of the funnel.
REFUELING WARNINGS
Do not overfill the fuel tank. The
pressure in an overfilled tank may
cause leakage and lead to fuel spray and
fire. WARNINGS
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 remove the fuel pump nozzle
from its fully inserted position when
refueling. 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. Stop refueling when the fuel pump
nozzle automatically shuts off for the
first time. Failure to follow this will fill the
expansion space in the fuel tank and could
lead to fuel overflowing. Wait at least 10 seconds before
removing the fuel pump nozzle to allow
any residual fuel to drain into the fuel tank.

injury. Read and follow all the instructions on
the pump island.
1. When you stop your vehicle, shift into
park (P) or neutral (N) and switch the
ignition off. 2. Press the button on the driver door to
open the fuel filler door. The fuel filler
door can take up to 15 seconds to open
before you can insert a fuel filler nozzle. 3.
Insert the fuel pump nozzle up to the first
notch on the nozzle A. Keep it resting
on the cover of the fuel tank filler pipe
opening. 4. Hold the fuel pump nozzle in position B
when refueling. Holding the fuel nozzle
in position A can affect the flow of fuel
and shut off the fuel nozzle before the
fuel tank is full. 5.
