Ford Expedition (2018 year). Manual — part 53

Obstacle Distance Indicator

(If

Equipped)

E190459

The system provides obstacle distance
indication through the information display.

As the distance to the obstacle decreases,
the indicator blocks illuminate and move
toward the vehicle icon. If there is no
obstacle detected, the distance indicator
blocks show greyed out.

When you shift to reverse (R), the side
sensing system provides audible warnings
when your vehicle is moving and obstacles
are detected within 24 in (60 cm) and are
inside the driving path of your vehicle.
When you stop your vehicle the audible
warning stops after two seconds.

Note:

Visual distance indication remains

on when the transmission is in reverse (R).

When you shift to drive (D) or any other
forward gear, for example, low (L), sport
(S) or any forward gear in manual
transmission, the side sensing system
provides audible and visual distance
warnings when your vehicle is moving
below a speed of 5 mph (8 km/h) and

obstacles are detected within 24 in
(60 cm) and are inside the driving path of
your vehicle. Once your vehicle reaches a
standstill condition, the audible warning
stops after two seconds and visual
indication stops after four seconds.

If the transmission is in neutral (N), the side
sensing system provides visual distance
indication only when your vehicle is moving
below a speed of 5 mph (8 km/h) and
there is a front or rear parking aid obstacle
detected, and the side obstacle is within
24 in (60 cm) from the side of your vehicle.
When you stop your vehicle the visual
distance indication stops after four
seconds.

If the side sensing system is not available,
the side distance indicator blocks do not
appear.

The side sensing system is not available
under the following condition:
•

If you switch the traction control
system off.

The side sensing system may not be
available until you have driven
approximately the length of your vehicle
in order for the system to reinitialize if:
•

You switch the ignition on, off and back
on.

•

Your vehicle remains stationary for over
two minutes.

•

The anti-lock brake system is
activated.

•

The traction control system is
activated.

•

When the steering wheel angle
information is not available, the side
sensing system is not available. The
vehicle must be driven at least 492 ft
(150 m) above 19 mph (30 km/h) to
recover the steering wheel angle
information.

ACTIVE PARK ASSIST

(If Equipped)

Parallel Parking, Perpendicular
Parking, Parallel Park Out Assist

WARNINGS

You must remain in your vehicle
when the system turns on. 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 sensors may not detect objects
in heavy rain or other conditions that
cause interference.

Active park assist does not apply the
brakes under any circumstances.

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.

Note:

The Blind Spot Information System

does not detect traffic alongside or behind
your vehicle during an Active Park Assist
maneuver.

The system detects an available parallel
or perpendicular parking space and
automatically steers your vehicle into the
space (hands-free) while you control the
accelerator, gearshift and brakes. The
system visually and audibly guides you to
park your vehicle.

If you are uncomfortable with the proximity
to any vehicle or object, you may choose
to override the system by grabbing the
steering wheel or by pressing the button.

Parallel Park Out Assist automatically
steers your vehicle out of a parallel parking
space (hands-free) while you control the
accelerator, gearshift and brakes. The
system visually and audibly guides you to
enter traffic.

The system may not correctly operate in
any of the following conditions:
•

You use a spare tire or a tire
significantly worn more than the other
tires.

•

One or more tires are improperly
inflated.

•

You try to park on a tight curve.

•

Something passes between the front
bumper and the parking space. For
example, a pedestrian or cyclist.

•

The edge of the neighboring parked
vehicle is high off the ground. For
example, a bus, tow truck or flatbed
truck.

•

The weather conditions are poor. For
example, during heavy rain, snow or
fog.

Note:

Keep the sensors on the bumper or

fascia free from snow, ice and large
accumulations of dirt. Covered sensors can
affect the system's accuracy. Do not clean
the sensors with sharp objects.

Note:

The sensors may not detect objects

with surfaces that absorb ultrasonic waves
or cause ultrasonic interference. For
example, motorcycle exhaust, truck air
brakes or horns.

Note:

Following a change in tire size, the

system must recalibrate and operation may
be impaired for a short time.

Do not use the system if:
•

You have attached a foreign object
close to the sensors on the front or rear
of your vehicle. For example, a bike rack
or trailer.

•

You attach an overhanging object to
the roof. For example, a surfboard.

•

A foreign object damages or obstructs
the front or rear bumper or side
sensors.

•

The correct tire size is not in use on your
vehicle. For example, a mini-spare tire.

Using Active Park Assist - Parallel
Parking

E146186

Press the Active Park Assist
button once to search for a
parallel parking space.

When driving at a speed less than 22 mph
(35 km/h), the system automatically scans
both sides of your vehicle for an available
parking space. The system displays a
message and a corresponding graphic to
indicate it is searching for a parking space.
Use the direction indicator to select
searching either to the left-hand side or
right-hand side of your vehicle.

Note:

If the direction indicators are not

used, the system defaults to the passenger
side of your vehicle.

E130107

Note:

You can also switch the system on

after you have already driven partially or
completely past a parking space. Press the
Active Park Assist button and the system
informs you if you have recently passed a
suitable parking space.

When the system finds a suitable space,
it displays a message and a tone sounds.
Stop your vehicle and follow the
instructions on the screen. If your vehicle
is moving very slowly, you may need to pull
forward a short distance before the system
is ready to park.

Note:

You must observe that the space the

system selects remains clear of obstructions
at all times during the maneuver.

Note:

Drive your vehicle within 5 ft (1.5 m)

and as parallel as possible to the other
vehicles while passing a parking space.

Note:

The system always offers the last

parking space it detects. For example, if your
vehicle detects multiple spaces while you
are driving, it offers the last one.

Note:

If driven above approximately 22 mph

(35 km/h), the system shows a message to
alert you to reduce your vehicle speed.

Automatically Steering into a Parking
Space

Note:

If your vehicle speed exceeds

approximately 6 mph (10 km/h) or you
interrupt the maneuver, the system switches
off and you need to take full control of your
vehicle.

When you shift the transmission into
reverse (R), with your hands off the
steering wheel and nothing obstructing its
movement, your vehicle steers itself into
the space (hands-free). The system
displays instructions to move your vehicle
backward and forward in the space.

E130108

When you believe your vehicle is properly
parked, or you hear a solid tone
accompanied by a display message, bring
your vehicle to a complete stop.

When the Active Park Assist maneuver is
complete, the system displays a message
and a tone sounds.

Note:

You are responsible for checking your

parked vehicle and making any necessary
corrections before leaving your vehicle.

Using Active Park Assist -
Perpendicular Parking

E146186

Press the Active Park Assist
button twice to search for a
perpendicular parking space.

When driving at a speed less than 19 mph
(30 km/h), the system displays a message
and a corresponding graphic to indicate it
is searching for a parking space. Use the
direction indicator to select searching
either to the left-hand side or right-hand
side of your vehicle.

Note:

If you do not make a selection, the

system defaults to the passenger side.
