2018 FORD EXPLORER parking sensors

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: If your vehicle is equipped with
MyKey ™, the sensing system cannot be
turned off when a MyKey ™ is present.
See
Principle of Operation (page 59).
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 alerts. Note:
Certain add-on devices installed
around the bumper or fascia may create
false alerts. 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. Remove the add-on device
to prevent false alerts.
Note: When a trailer is connected to your
vehicle, the rear parking aid may detect the
trailer and therefore provide an alert. Disable
the rear parking aid when a trailer is
connected to prevent the alert.
The sensing system warns the driver of
obstacles within a certain range of your
vehicle. The system turns on automatically
whenever you switch the ignition on.
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 105).
If a fault is present in the system, a warning
message appears in the information
display. See
Information Messages
(page 119).
REAR PARKING AID
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. 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 105). 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. 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.

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.
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 taking full control of
your vehicle after pressing the active park
assist button.
Keep your hands, hair, clothing and any
loose items clear of the steering wheel
when using active park assist.
The sensors are on the front and rear
bumpers. Note:
Keep the sensors free from snow, ice
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, for
example motorcycle exhausts, truck air
brakes or horns.
Note: If you change any tires, the system
must recalibrate and may not correctly
operate for a short time.
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
surfboard.

Selecting an Active Park Assist Mode Press the button once to
activate parallel parking. Press
the button a second time to
activate perpendicular parking. If you press
the button again the system switches off.
If your vehicle is parked and after you
switch the ignition on, you can use the
information display to toggle through the
modes. Press the button to switch the
system on and open the system menu in
the information display.
Note: If your vehicle is parked, the default
mode is parallel park out assist. However if
you did not use active park assist to parallel
park your vehicle, use the information
display to select park out assist.
Note: You can only repeatedly press the
active park assist button to toggle through
the modes after moving your vehicle
approximately 33 ft (10 m).
To toggle through the modes, use the
buttons on the information display to
select the following:
• Parallel parking.
• Perpendicular parking.
• Parallel park out assist.
• Switch the system off.
Note: There is no time limit for toggling
through the modes. Parallel Parking
The system detects available parallel
parking spaces and steers your vehicle into
the space. You control the accelerator,
gearshift and brakes. The system visually
and audibly guides you into a parallel
parking space. Press the button once to search
for a parking space.
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 vehicle speed is less than
22 mph (35 km/h), the system scans both
sides of your vehicle for an available
parking space. A message and a graphic
appear in the information display to
indicate the system is searching for a
parking space. Use the direction indicator
to be offered parking spaces on either the
left-hand side or right-hand side of your
vehicle.
Note: The system scans both sides of your
vehicle and offers parking spaces one side
at a time if you do not use the direction
indicator.
Note: The system defaults to the passenger
side if you do not use the direction indicator. Drive your vehicle approximately 3 ft (1 m)
and parallel to the other parked vehicles
when searching for a parking space.

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.
Troubleshooting Possible Cause
Symptom
You may have switched the traction control off.
The system does not search for
a parking space.
The transmission is in reverse (R). Your vehicle must
be moving forward to be able to detect a parking space.
The sensors may be blocked. For example, snow, ice
or dirt buildup. Blocked sensors can affect how the
system functions.
The system does not offer a
parking space.
There is not enough room in the parking space for your
vehicle to safely park.
There is not enough space for the parking maneuver on
the opposite side of the parking space.
The parking space is more than
5 ft (1.5 m) or less than
2 ft (0.5 m) away.
The vehicle speed is greater than
22 mph (35 km/h)
for parallel parking or greater than 19 mph (30 km/h)
for perpendicular parking.
You recently disconnected or replaced the battery. After
you reconnect the battery you must drive your vehicle
on a straight road for a short period of time.
Your vehicle is rolling in the opposite direction of the
current transmission position. For example, rolling
forward when in reverse (R).
The system does not correctly
position your vehicle in a
parking space.
An irregular curb along the parking space prevents the
system from correctly aligning your vehicle.

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. CROSS TRAFFIC ALERT
(If
Equipped) WARNING:
Do not use the cross
traffic alert system as a replacement for
using the interior and exterior mirrors or
looking over your shoulder before reversing
out of a parking space. The cross traffic
alert system is not a replacement for
careful driving. WARNING:
The system may not
operate properly during severe weather
conditions, for example snow, ice, heavy
rain and spray. Always drive with due care
and attention. Failure to take care may
result in a crash.
The system is designed to alert you of
vehicles approaching from the sides when
you shift into reverse (R).
Using the Cross Traffic Alert
System
The system is designed to detect vehicles
that approach with a speed up to
37 mph
(60 km/h). Coverage decreases when the
sensors are partially, mostly or fully
obstructed. Slowly reversing helps increase
the coverage area and effectiveness.
The system turns on when you start the
engine and you shift into reverse (R). The
system turns off when you shift out of
reverse (R).
