Ford Fusion Hybrid / Fusion Energi (2018 year). Manual — part 36

Low:

Low (L) is designed to mimic the enhanced
engine braking available in non-hybrid
vehicles. Low gear will produce high engine
speeds to provide necessary engine
braking. This is normal and will not damage
your vehicle. In low gear, the gas engine
will remain on more often than in drive (D).

Reverse:

In reverse (R), vehicle speed is limited to
22 mph (35 km/h).

Battery:

Your hybrid is equipped with a high voltage
battery. A cool battery maintains battery
life and provides the best possible
performance. The high voltage battery is
cooled by cabin air drawn from vent holes
in the trim panels behind the rear seats.
Avoid placing objects at the vent holes that
block airflow to the high voltage battery.

Engine:

The engine speed in your hybrid is not
directly tied to your vehicle speed. Your
vehicle's engine and transmission are
designed to deliver the power you need at
the most efficient engine speed. During
heavy accelerations, your hybrid may reach
high engine speeds (up to 6000 RPM).

In prolonged mountainous driving, you may
see the engine speed changing without
your input. This is intentional and maintains
the battery charge level. You may also
notice during extended downhill driving
that your engine continues to run instead
of shutting off.

During this engine braking, the engine stays
on, but it is not using any fuel. You may also
hear a slight whine or whistle when
operating your vehicle. This is the normal
operation of the electric generator in the
hybrid system.

During certain events (such as vehicle
servicing) your low voltage 12-volt battery
may become disconnected or disabled.
Once the battery is reconnected and after
driving the vehicle, the engine may
continue to operate for three to five
seconds after the key is turned to off. This
is a normal condition.

Braking:

Your hybrid is equipped with standard
hydraulic braking and regenerative braking.
Regenerative braking is performed by your
transmission and it captures brake energy
and stores it in your high voltage battery.

Driving to Optimize Fuel Economy

Note: Having your engine running is not
always an indication of inefficiency. In some
cases, it is actually more efficient than
driving in electric mode.

Your fuel economy should improve
throughout your hybrid's break-in period.
As with any vehicle, your driving habits and
accessory usage can significantly impact
your fuel economy. For best results, keep
in mind these tips:

•

Keep the tires properly inflated and
only use the recommended size.

•

Aggressive driving increases the
amount of energy required to move
your vehicle. In general, you can
achieve better fuel economy with mild
to moderate acceleration and
deceleration. Moderate braking is
particularly important since it allows
you to maximize the energy captured
by the regenerative braking system.

Additional Tips:
•

Do not carry extra loads.

•

Be mindful of adding external
accessories that may increase
aerodynamic drag.

•

Observe posted speed limits.

•

Perform all scheduled maintenance.

•

There is no need to wait for your engine
to warm up. The vehicle is ready to
drive immediately after starting.

PLUG-IN HYBRID VEHICLE
OPERATION

Plug-in Power Mode and Hybrid
Mode

You must plug in your Energi vehicle
regularly for optimal use of the high
voltage battery's extended range
capability. Charging your vehicle adds
electrical energy. This energy is used to
propel the vehicle in plug-in power mode.

Estimated electric range is shown in blue
next to gasoline range at the bottom of the
right information display. You can also
configure MyView to include detailed
vehicle range information. See Gauges
(page 89).

The system maximizes the use of
electric-only operation in plug-in power
mode. System conditions may require
engine operation; however, the system
uses plug-in power whenever possible.

When your plug-in power is depleted, the
powertrain system will automatically
switch to hybrid mode. Hybrid mode uses
both the gasoline engine and electric
motor to power your vehicle and maximize
fuel economy.

EV Modes

E144814

Your vehicle contains selectable
EV modes through the EV button
on the center console.

These modes are available when your
vehicle can run under high voltage battery
power. With your vehicle in driving mode,
you can change EV modes with each press
of the EV button. The current mode will be
displayed in the left-hand instrument
cluster screen.

Auto EV

E155152

This mode provides an
automatic use of high voltage
battery power during the drive,

staying in electric mode when possible and
running the engine when needed. This
mode will be the only one available if the
plug-in power has been depleted.

EV Now

E144814

This mode provides an electric
only driving experience. The
left-hand information display

changes to a screen displaying your
average miles or kilometers per charge
along with EV specific tools and functions.

Your vehicle may accelerate more slowly
and the top speed may be lower in EV Now
mode than in Auto EV mode.

You can enable your engine at any time by
using one of the following methods:

1.

Press the OK button on the left 5–way
steering wheel control while viewing
the miles or kilometers per charge
screen. Your vehicle will enable the
engine as needed, and will
automatically return to EV Now after
eight seconds or when the engine is no
longer needed.

2. Press the accelerator pedal fully. A pop

up message will appear. Press OK on
the left-hand steering wheel button to
activate as needed. The message will
disappear if you release the accelerator
pedal.

3. Press the EV button. This will change

the mode to EV Later and permit
engine operation.

Your vehicle may automatically enter
Engine Enabled mode if system conditions
require it. A engine enabled message will
display if this occurs. This is normal
function, and your vehicle will return to EV
Now when possible.

Your vehicle may enter Enable Engine
mode if the climate control is in a defrost
mode and the outside temperature is cold.
A engine enabled message will display if
this occurs. If defrost is not needed, select
a different climate control mode to permit
EV Now.

When you enable EV Now, a blue EV icon
displays in the left-hand information
display. If your vehicle is in the Engine
Enabled mode, the EV icon will be yellow.

EV Now will automatically exit when the
Plug in power has been depleted.

EV Later

E151263

This mode saves most of the
high voltage battery plug in
power for future use (for

example, your initial drive is at high speeds
on open roads, but later your drive will be
at low speeds in an urban area where
plug-in power usage is most efficient).
Your vehicle will run the engine as needed
and keep most of the high voltage battery
plug in power for later use in Auto Mode or
EV Now mode.

When you enable EV Later, a white EV
Later icon appears on the left-hand
information display.

The EV Later mode will automatically reset
to EV Auto mode when you power your
vehicle off. You may press the EV button
twice during the next drive to return to EV
Later mode, if desired.

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 97).

Settings

ECO Cruise

Driver Assist

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
106).

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
and Fusion 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?
