Ford C-MAX Hybrid / Energi (2016 year). Manual - part 34

ECO Cruise

Note: ECO Cruise is available as a separate
feature on Energi vehicles only. On non
plug-in vehicles it is included in EcoSelect.

This feature saves vehicle energy by
relaxing acceleration compared to
standard cruise control. For example, your
vehicle may temporarily lose speed when
going uphill. When set to on, ECO appears
in the information display when cruise
control is on.

You can switch it on or off in through the
information display.  See General
Information (page 93).

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 Information Messages (page
101).

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

190).

Can I tow the hybrid behind my motor home

with all four wheels down?

ECOSELECT

EcoSelect is a drive mode for non-plugin
vehicles designed to offer the best possible
fuel economy with only a slight impact to
vehicle performance and comfort.

E198654

To switch EcoSelect on, press
the ECO button.

A graphic displays on your information
display when EcoSelect is on.

Your vehicle will remember the last
selected mode whenever you start your
vehicle.

EcoSelect allows your vehicle to operate
more efficiently. You will notice:
•

Less aggressive heating and cooling.

•

Softer acceleration.

•

More regenerative braking.

•

Changes in engine behavior.

•

ECO cruise control activation.
