2018 FORD EXPEDITION sensor

PRINCIPLE OF OPERATION
WARNING: To help avoid personal
injury, always use caution when in
reverse (R) and when using the sensing
system. WARNING: The system may not
detect objects with surfaces that absorb
reflection. Always drive with due care
and attention. Failure to take care may
result in a crash. WARNING:
Traffic control
systems, inclement weather, air brakes,
external motors and fans may affect the
correct operation of the sensing
system.This may cause reduced
performance or false alerts. WARNING:
The system may not
detect small or moving objects,
particularly those close to the ground.
Note: Certain add-on devices installed
around the bumper or fascia may create
false beeps. For example, large trailer
hitches, bike or surfboard racks, license plate
brackets, bumper covers or any other device
that may block the normal detection zone
of the system.
Note: Keep the sensors, located on the
bumper or fascia, free from snow, ice and
large accumulations of dirt. If the sensors
are covered, the system ’s accuracy can be
affected. Do not clean the sensors with
sharp objects.
Note: If your vehicle sustains damage to
the bumper or fascia, leaving it misaligned
or bent, the sensing zone may be altered
causing inaccurate measurement of
obstacles or false alarms. See your
authorized technician. Note:
When a trailer is connected to your
vehicle, the rear parking aid may detect the
trailer and therefore provide warnings.
Disable the rear parking aid when a trailer
is connected to prevent these warnings.
Note: The sensing system cannot be turned
off when a MyKey is present. See Principle
of Operation
(page 61).
We recommend that you take some time
to get to know the system and its
limitations by reading this section.
The sensing system warns the driver of
obstacles within a certain range of your
vehicle. The system automatically turns
on each time you switch the ignition on.
When receiving a detection warning, the
radio volume reduces to a predetermined
level. After the warning goes away, the
radio volume returns to the previous level. You can turn the system on or
off by pressing the parking aid
button. If your vehicle does not
have a parking aid button, the system can
be switched off through the information
display menu or from the pop-up message
that appears once you shift the
transmission into reverse (R). See General
Information
(page 111).
If a fault is present in the system, a warning
message appears in the information
display and does not allow you to switch
the system on. See
Information
Messages (page 123).
If a sensor is blocked and cannot function,
the system becomes disabled and a
warning message appears in the
information display. The system returns to
a normal state once the blockage is
cleared.

REAR PARKING AID (IF EQUIPPED)
The rear sensors are only active when the
transmission is in reverse (R). As your
vehicle moves closer to the obstacle, the
rate of the audible warning increases.
When the obstacle is less than
12 in
(30 cm) away, the warning sounds
continuously. If the system detects a
stationary or receding object farther than
12 in (30 cm)
from the corners of the
bumper, the tone sounds for only three
seconds. Once the system detects an
object approaching, the warning sounds
again. Coverage area of up to
6 ft (1.8 m) from
the rear bumper. There may be decreased
coverage area at the outer corners of the
bumper. The system detects certain objects while
the transmission is in reverse (R) :
•
Your vehicle is moving toward a
stationary object at a speed of
3 mph
(5 km/h) or less.
• Your vehicle is not moving, but a
moving object is approaching the rear
of your vehicle at a speed of
3 mph
(5 km/h) or less.
• Your vehicle is moving at a speed of
less than 3 mph (5 km/h) and a moving
object is approaching the rear of your
vehicle at a speed of less than
3 mph
(5 km/h).
The system provides audio warnings only
when your vehicle is moving or when your
vehicle is stationary and the detected
obstacle is less than
12 in (30 cm) away
from the bumper.
Obstacle Distance Indicator
(If
Equipped)
The system provides obstacle distance
indication through the information display.
The distance indicator displays when the
transmission is in reverse (R).
The indicator displays:
• As the distance to the obstacle
decreases the indicator blocks
illuminate and move towards the
vehicle icon.
• If there is no obstacle detected, the
distance indicator blocks are grayed
out.
FRONT PARKING AID (IF EQUIPPED)
The front sensors are active when the
transmission is in any position other than
park (P) and your vehicle is traveling at low
speed.
222
Expedition (TB8) Canada/United States of America, enUSA, Edition date: 201708, Third-Printing- Parking AidsE130178

Coverage area of up to 28 in (70 cm) from
the front bumper. The coverage area
decreases at the outer corners.
When your vehicle approaches an object,
a warning tone sounds. When your vehicle
moves closer to an object, the warning
tone repeat rate increases. The warning
tone sounds continuously when an object
is
12 in (30 cm) or less from the front
bumper.
You can switch the system off through the
information display menu or from the
pop-up message that appears once you
shift the transmission into reverse (R). See
General Information
(page 111). If your
vehicle has a parking aid button, you can
switch the system off by pressing the
button.
Obstacle Distance Indicator
(If
Equipped)
The system provides obstacle distance
indication through the information display.
The indicator displays:
• As the distance to the obstacle
decreases the indicator blocks
illuminate and move towards the
vehicle icon.
• If there is no obstacle detected, the
distance indicator blocks are grayed
out. If the transmission is in reverse (R), the
front sensing system provides audio
warnings when your vehicle is moving and
the detected obstacle is moving towards
your vehicle. Once the vehicle is stationary,
the audio warning will be stopped after 2
seconds. Visual indication is always
present in reverse (R).
If the transmission is in drive (D) or any
other forward gear (for example, low (L),
sport (S) or any forward gear in a manual
transmission), the front sensing system
provides audio and visual warnings when
your vehicle is moving below a speed of
5 mph (8 km/h) and an obstacle is located
inside the detection area. Once the vehicle
is stationary, the audio warning will be
stopped after 2 seconds and the visual
indication stops after 4 seconds. If the
obstacles detected are within
12 in
(30 cm), the visual indication remains on.
If the transmission is in neutral (N), the
system provides visual indication only
when your vehicle is moving at
5 mph
(8 km/h) or below and an obstacle is
located inside the detection area. Once
your vehicle is stationary, the visual
indication will stop after 4 seconds.
SIDE SENSING SYSTEM
(IF
EQUIPPED)
The side sensing system uses the front and
rear side sensors to detect and map
obstacles within the vehicle's driving path,
located near the sides of your vehicle. The
side sensors are active when the
transmission is in any position other than
park (P).
Note: Obstacles that enter the side
detection area without being detected and
mapped by the front or rear side sensors will
not be detected.
223
Expedition (TB8) Canada/United States of America, enUSA, Edition date: 201708, Third-Printing- Parking AidsE187330

The side sensing system may not be
available until you have driven

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) WARNING:
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. WARNING:
The sensors may not
detect objects in heavy rain or other
conditions that cause interference. WARNING:
Active park assist does
not apply the brakes under any
circumstances. WARNING:
You are responsible
for controlling your vehicle at all times.
The system is designed to be an aid and
does not relieve you of your responsibility
to drive with due care and attention.
Failure to follow this instruction could
result in the loss of control of your
vehicle, personal injury or death.
Active park assist is a multi-step process
and may require you to shift the
transmission multiple times. Follow the
onscreen instructions until the parking
maneuver is complete.

and large accumulations of dirt.
Note: Do not cover up the sensors.
Note: Do not clean the sensors with sharp
objects.
Note: The sensors may not detect objects
with surfaces that absorb ultrasonic waves.
The sensors may falsely detect objects due
to ultrasonic interference caused by
motorcycle exhausts, truck air brakes or
horns, for example.
Note: If you change any tires, the system
must recalibrate and may not correctly
operate for a short time.
225
Expedition (TB8) Canada/United States of America, enUSA, Edition date: 201708, Third-Printing- Parking Aids

The system may not correctly operate in
any of the following conditions:
•
You use a spare tire or a tire that is
significantly worn more than the other
tires.
• One or more tires are incorrectly
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, fog,
high humidity and high temperatures.
Do not use the system if:
• You have attached an add-on
accessory close to the sensors on the
front or rear of your vehicle. For
example, a bike rack or trailer.
• You have attached an overhanging
object to the roof. For example, a

to continue the maneuver, it may instruct
you to stop your vehicle. The system may
not provide any further instruction. Steering
assistance continues to operate but you
must decide if it is safe to continue the
maneuver. After the system directs your vehicle to a
position where you can exit the parking
space in a forward movement, a message
appears instructing you to take full control
of your vehicle. Generally, hand-over is
when your vehicle is still inside the parking
space.
Note:
Parallel Park Out Assist may not be
available when the clearance to the front
or the rear of your vehicle is too small.
Note: If the vehicle speed exceeds
approximately 6 mph (9 km/h), you
interrupt the maneuver, or the system
switches off, you must take full control of
your vehicle.
Note: You are responsible for controlling
your vehicle and making sure the path is
clear prior to pulling into traffic.

in poor visibility, for example fog, heavy
rain, spray or snow. WARNING:
Do not use the system
when towing a trailer with aftermarket
trailer brake controls. Aftermarket trailer
brakes will not function properly when
you switch the system on because the
brakes are electronically controlled.
Failing to do so may result in loss of
vehicle control, which could result in
serious injury. WARNING:
Do not use tire sizes
other than those recommended because
this can affect the normal operation of
the system. Failure to do so may result
in a loss of vehicle control, which could
result in serious injury. WARNING: Adaptive cruise control
may not detect stationary or slow
moving vehicles below 6 mph (10 km/h). WARNING: Adaptive cruise control
does not detect pedestrians or objects
in the road. WARNING: Adaptive cruise control
does not detect oncoming vehicles in the
same lane. WARNING: Adaptive cruise control
is not a crash warning or avoidance
system. WARNING:
Do not use adaptive
cruise control with a snow plow blade
installed.
Note: It is your responsibility to stay alert,
drive safely and be in control of the vehicle
at all times.
The system adjusts your vehicle speed to
maintain the set gap between you and the
