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
automatically stop when no longer needed.

Note: Cold temperatures will affect the
engine warm up time and the low engine
use mode may operate more frequently.

Note: An oil change is not required but gives
you the option of not running a low engine
use cycle. Resetting the oil life monitoring
system will suspend the low engine use
mode.

HYBRID VEHICLE FREQUENTLY ASKED QUESTIONS

Answer

Question

The high voltage battery is electrically isol-

ated from the rest of the vehicle when the

key is off. When you switch the key on, high

voltage contactors inside the battery are

closed to make the electricity available to

the motor and 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.

What are the series of clicks from the cargo
area when I first turn the key in the ignition?

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, the engine may not be

required to operate these functions.)

Why does the engine sometimes start at

key-on?

There are several reasons the engine stays

on for an extended amount of time when

you first start it. One common reason is to

make sure that the emissions components

are warm enough to minimize tailpipe

emissions. As the climate gets cooler, this

engine-on time is extended.

Why does it take a long time before the

engine shuts down?

The engine is required to turn on above this

speed to protect the transmission hard-

ware.

Why does my engine never shut down

above 85 mph (137 km/h)

In order to make sure that the climate

control system can begin heating the cabin

or defrosting the windshield as soon as a

driver requests it, the engine coolant

temperature has to be kept sufficiently hot.

Keeping the engine on is required to main-

tain the correct coolant temperature.

Why does my engine stay on when it is

extremely cold outside?

Answer

Question

Your vehicle's engine and transmission are

designed to deliver the power you need at
the 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 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 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 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 designed

to 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.
