Ford Fusion (2018 year). Manual — part 52

The sensor on the left-hand side is only
partially obstructed and zone coverage on

the right-hand side is maximized.

E142441

Zone coverage also decreases when
parking at narrow angles. The sensor on
the left-hand side is mostly obstructed and
zone coverage on that side is severely
reduced.

System Lights, Messages and
Audible Alerts

E142442

When the system detects a vehicle, an
indicator illuminates in the exterior mirror
on the side the approaching vehicle is
coming from. A tone sounds and a
message appears in the information
display.

Note: In exceptional conditions, the system
could alert you even when there is nothing
in the detection zone, for example a vehicle
passing in the distance.

Blocked Sensors

E205199

The sensors are behind the rear bumper
on both sides of your vehicle.

Note: Keep the sensors free from snow, ice
and large accumulations of dirt.

Note: Do not cover the sensors with bumper
stickers, repair compound or other objects.

Note: Blocked sensors could affect system
performance.

If the sensors are blocked, a message may
appear in the information display when
you shift into reverse (R). See
Information Messages (page 105).

System Limitations

The system may not correctly operate
when any of the following occur:
•

The sensors are blocked.

•

Adjacently parked vehicles or objects
are obstructing the sensors.

•

Vehicles approach at speeds greater
than 37 mph (60 km/h).

•

The vehicle speed is greater than 7 mph
(12 km/h).

•

You reverse out of an angled parking
space.

System Errors

If the system detects a fault a message
displays. See General Information (page
96).

Switching the System Off and On

You can temporarily switch the system off
using the information display. See General
Information (page 96). When you switch
system off, a message displays. See
Information Messages (page 105).

Note: The system turns on each time you
switch the ignition on and you shift into
reverse (R). If you temporarily switch the
system off, it turns on the next time you
switch the ignition on.

Note: The system may not correctly operate
when towing a trailer. For vehicles with a
trailer tow module and tow bar approved
by us, the system turns off when you attach
a trailer. For vehicles with an aftermarket
trailer tow module or tow bar, we
recommend that you switch the system off
when you attach a trailer.

To permanently switch the system off,
contact an authorized dealer.

STEERING

Electric Power Steering

WARNINGS

The electric power steering system
has diagnostic checks that
continuously monitor the system. If

a fault is detected, a message displays in
the information display. Stop your vehicle
as soon as it is safe to do so. Switch the
ignition off. After at least 10 seconds,
switch the ignition on and watch the
information display for a steering system
warning message. If a steering system
warning message returns, have the system
checked by an authorized dealer.

If the system detects an error, you
may not feel a difference in the
steering, however a serious condition

may exist. Obtain immediate service from
an authorized dealer, failure to do so may
result in loss of steering control.

Your vehicle has an electric power steering
system. There is no fluid reservoir. No
maintenance is required.

If your vehicle loses electrical power while
you are driving, electric power steering
assistance is lost. The steering system still
operates and you can steer your vehicle
manually. Manually steering your vehicle
requires more effort.

Extreme continuous steering may increase
the effort required for you to steer your
vehicle. This increased effort prevents
overheating and permanent damage to
the steering system. You do not lose the
ability to steer your vehicle manually.
Typical steering and driving maneuvers
allow the system to cool and return to
normal operation.

Steering Tips

If the steering wanders or pulls, check for:
•

Correct tire pressures.

•

Uneven tire wear.

•

Loose or worn suspension
components.

•

Loose or worn steering components.

•

Improper vehicle alignment.

Note: A high crown in the road or high
crosswinds may also make the steering
seem to wander or pull.

Adaptive Learning

The electronic power steering system
adaptive learning helps correct road
irregularities and improves overall handling
and steering feel. It communicates with
the brake system to help operate
advanced stability control and accident
avoidance systems. Additionally, whenever
the battery is disconnected or a new
battery installed, you must drive your
vehicle a short distance before the system
relearns the strategy and reactivates all
systems.

PRE-COLLISION ASSIST

(If

Equipped)

WARNINGS

At all times, you are responsible for
controlling your vehicle, supervising
the system and intervening, if

required. Failure to take care may result in
the loss of control of your vehicle, serious
personal injury or death.

The system is designed to aid the
driver. It is not intended to replace
your attention and judgment. You are

still responsible to drive with due care and
attention.

The system does not detect vehicles
that are driving in a different
direction, pedestrians at night,

cyclists or animals. Failure to take care
may result in the loss of control of your
vehicle, serious personal injury or death.

The system does not operate during
hard acceleration or steering. Failure
to take care may lead to a crash or

personal injury.

The system may fail or operate with
reduced function during cold and
severe weather conditions. Snow,

ice, rain, spray and fog can adversely affect
the system. Keep the front camera and
radar free of snow and ice. Failure to take
care may result in the loss of control of
your vehicle, serious personal injury or
death.

In situations where the vehicle
camera has limited detection
capability, this may reduce system

performance. These situations include but
are not limited to direct or low sunlight,
vehicles at night without tail lights,
unconventional vehicle types, pedestrians
with complex backgrounds, running

WARNINGS

pedestrians, partly obscured pedestrians,
or pedestrians that the system cannot
distinguish from a group. Failure to take
care may result in the loss of control of
your vehicle, serious personal injury or
death.

The system cannot help prevent all
crashes. Do not rely on this system
to replace driver judgment and the

need to maintain a safe distance and
speed.

Using the Pre-Collision Assist
System

The system is active at speeds above
approximately 3 mph (5 km/h) and
pedestrian detection is active at speeds
up to 50 mph (80 km/h).

E156130

If your vehicle is rapidly approaching
another stationary vehicle, a vehicle
traveling in the same direction as yours, or
a pedestrian within your driving path, the
system is designed to provide three levels
of functionality:

1.

Alert

2. Brake Support

3. Active Braking

E156131

Alert: When activated, a red warning light
flashes, an audible warning chime sounds
and a warning message shows in the
information display.

Brake Support: Assists the driver in
reducing collision speed by preparing the
brake system for rapid braking. Brake
support does not automatically activate
the brakes, but if the brake pedal is pressed
even lightly by the driver, brake support
could add additional braking up to full
force.

Active Braking: Active braking may
activate if the system determines that a
collision is imminent. The system may help
the driver reduce impact damage or avoid
the crash completely.

Note: If you perceive Pre-Collision Assist
alerts as being too frequent or disturbing,
then you can reduce the alert sensitivity,
though the manufacturer recommends
using the highest sensitivity setting where
possible. Setting lower sensitivity would
lead to fewer and later system warnings.

Adjusting the Pre-Collision Assist
Settings

You can adjust the Pre-Collision Assist
settings by using the information display
control. See General Information (page
96).

If required, you can switch active braking
off using the information display control.
See General Information (page 96).

Note: Active braking automatically turns
on every time you switch the ignition on.
