PRINCIPLE OF OPERATION
WARNING: Hill descent control
cannot control descent in all surface
conditions and circumstances, such as
ice or extremely steep grades. Hill
descent control is a driver assist system
and cannot substitute for good judgment
by the driver. Failure to do so may result
in loss of vehicle control, crash or serious
injury. WARNING:
Hill descent control
does not provide hill hold at zero miles
per hour (0 kilometers per hour). When
stopped, you must apply the parking
brake or place the vehicle in P (Park), or
it may roll away.
Hill descent control allows you to set and
maintain vehicle speed while descending
steep grades in various surface conditions.
Hill descent control can maintain vehicle
speeds on downhill grades between 2 mph
(3 km/h) and 12 mph (20 km/h). Above 20
mph (32 km/h), the system remains
armed, but you cannot use the system to
set or maintain the descent speed.
Hill descent control requires a cooling
down interval after a period of sustained
use. The amount of time that the feature
can remain active before cooling varies
with conditions. The system provides a
warning in the message center and a tone
sounds when the system is about to
disengage for cooling. At this time,
manually apply the brakes as needed to
maintain descent speed. USING HILL DESCENT
CONTROL Press and release the hill
descent button on the
instrument panel. The button
illuminates and a chime sounds when you
switch this feature on.
To increase descent speed, press the
accelerator pedal until you reach the
desired speed. To decrease descent
speed, press the brake pedal until you
reach the desired speed.
Whether accelerating or decelerating, once
you reach the desired descent speed,
remove your feet from the pedals and hill
descent control maintains the chosen
vehicle speed.
Note: You may observe noise from the ABS
pump motor during hill descent control
operation. This is a normal characteristic of
the ABS and should be no reason for
concern.
Hill Descent Modes
• At speeds between
2 mph (3 km/h)
and 20 mph (32 km/h): When you
press this button, the light flashes
indicating this feature is active. Your
vehicle maintains the speed you desire
while in this mode.
• At speeds between
20 mph (32 km/h)
and 40 mph (64 km/h): When you
press this button, the light is solid and
a message appears in the information
display indicating this feature is active.
Your vehicle does not maintain the
speed you desire and you cannot set
your descent speed.

(If Equipped)

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 64).
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 113).
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 125).
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.

Expedition (TB8) Canada/United States of America, enUSA, Edition date: 201808, Second-Printing Parking AidsE139213

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 greyed
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.
226
Expedition (TB8) Canada/United States of America, enUSA, Edition date: 201808, Second-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 113). 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 turn grey. 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 stops after two 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 inside
the detection area. Once the vehicle is
stationary, the audio warning stops after
two seconds and the visual indication
stops after four 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
inside the detection area. Once your vehicle
is stationary, the visual indication stops
after four 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.
227
Expedition (TB8) Canada/United States of America, enUSA, Edition date: 201808, Second-Printing Parking AidsE187330

Coverage area is up to 24 in (60 cm) from
the sides of your vehicle.
When the system detects an object close
to the side of your vehicle, an audible
warning sounds. As your vehicle moves
closer to obstacles within the driving path
of your vehicle, the rate of the audible
warning increases.
Obstacle Distance Indicator (If
Equipped) 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.
228
Expedition (TB8) Canada/United States of America, enUSA, Edition date: 201808, Second-Printing Parking AidsE187810 E190459

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) 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
