2021 FORD EXPEDITION warning

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 68).
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 119).
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 129).
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.

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

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. 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.
• The front bumper, rear bumper or the
side sensors are damaged.
• The correct tire size is not in use on your
vehicle. For example, a mini-spare tire.

Possible Cause
Symptom
A parked vehicle has a high attachment. For example,
a salt sprayer, snowplow or moving truck bed.
The parking space length or position of parked objects
changes after your vehicle passes the space.
The temperature around your vehicle quickly changes.
For example, driving from a heated garage into the cold,
or after leaving a car wash.
REAR VIEW CAMERA WARNING: The rear view camera
system is a reverse aid supplement
device that still requires the driver to use
it in conjunction with the interior and
exterior mirrors for maximum coverage. WARNING:
Objects that are close
to either corner of the bumper or under
the bumper, might not be seen on the
screen due to the limited coverage of the
camera system. WARNING:
Reverse your vehicle
slowly. Failure to follow this instruction
could result in the loss of control of your
vehicle, personal injury or death. WARNING:
Use caution when the
rear cargo door is ajar. If the rear cargo
door is ajar, the camera will be out of
position and the video image may be
incorrect. All guidelines disappear when
the rear cargo door is ajar. Failure to
follow this instruction could result in
personal injury. WARNING:
Use caution when
turning camera features on or off when
the transmission is not in park (P). Make
sure your vehicle is not moving. The rear view camera system provides a
video image of the area behind your
vehicle.
