FORD EXPEDITION 2020 Service Manual

•
Crash sensors and monitoring system
with readiness indicator.
The seatbelt pretensioners and rear
inflatable seatbelts are designed to
activate in frontal, near-frontal and side
crashes, and in rollovers. The seatbelt
pretensioners at the front seating positions
are designed to tighten the seatbelts firmly
against the occupant’ s body when
activated. This helps increase the
effectiveness of the seatbelts. In frontal
crashes, the seatbelt pretensioners can be
activated alone or, if the crash is of
sufficient severity, together with the front
airbags.
FASTENING THE SEATBELTS
Standard belts shown, inflatable belts
similar
The front outboard and rear safety
restraints in the vehicle are combination
lap and shoulder belts. 1. Insert the seatbelt tongue into the
proper buckle (the buckle closest to
the direction the tongue is coming
from) until you hear a snap and feel it
latch. Make sure you securely fasten
the tongue in the buckle. 2. To unfasten, press the release button
and remove the tongue from the
buckle.

The retractor for the third row center
seatbelt is in the roof.
To fasten the seatbelt:
1. Pull the belt out steadily. It may lock if
you pull it sharply or if the vehicle is on
a slope.
2. Insert the smaller tongue into the smaller buckle to the left of the center
seat.
3. Pull the larger tongue across the lap and insert it into the buckle to the right
of the center seat.
Note: If in constant use, you can leave the
belt buckled in the smaller buckle. When it
is not in use, or when you fold or move the
rear seats, you should release the belt from
the smaller buckle. Using the tongue of the
adjacent seatbelt, press the red button on
the smaller buckle. Using Seatbelts During Pregnancy WARNING: Always ride and drive
with your seatback upright and properly
fasten your seatbelt. Fit the lap portion
of the seatbelt snugly and low across
the hips. Position the shoulder portion of
the seatbelt across your chest. Pregnant
women must follow this practice. See
the following figure.
39
Expedition (TB8) Canada/United States of America, enUSA, Edition date: 201907, Third-Printing- SeatbeltsE275033

Pregnant women should always wear their
seatbelt. Position the lap belt portion of a
combination lap and shoulder belt low
across the hips below the belly and worn
as tight as comfort allows. Position the
shoulder belt to cross the middle of the
shoulder and the center of the chest.
Seatbelt Locking Modes
WARNING: If your vehicle is
involved in a crash, have the seatbelts
and associated components inspected
as soon as possible. Failure to follow this
instruction could result in personal injury
or death.
All safety restraints in the vehicle are
combination lap and shoulder belts. The
driver seatbelt has the vehicle sensitive
locking mode. The front outboard
passenger and rear seatbelts have both
the vehicle sensitive locking mode and the
automatic locking mode. Vehicle Sensitive Mode
This is the normal retractor mode, which
allows free shoulder belt length
adjustment to your movements and
locking in response to vehicle movement.
For example, if the driver brakes suddenly
or turns a corner sharply, or the vehicle
receives an impact of about
5 mph
(8 km/h) or more, the combination
seatbelts lock to help reduce forward
movement of the driver and passengers.
In addition, the retractor is designed to lock
if you pull the webbing out too quickly. If
the seatbelt retractor locks, slowly lower
the height adjuster to allow the seatbelt
to retract. If the retractor does not unlock,
pull the seatbelt out slowly then feed a
small length of webbing back toward the
stowed position. For rear seatbelts, recline
the rear seat backrest or push the seat
backrest cushion away from the seatbelt.
Feed a small length of webbing back
toward the stowed position.
Automatic Locking Mode
In this mode, the shoulder belt
automatically pre-locks. The belt still
retracts to remove any slack in the
shoulder belt. The automatic locking mode
is not available on the driver seatbelt.
When to Use the Automatic Locking
Mode
Use this mode when you install a child
safety seat, except a booster, in the
passenger front or rear seating positions.
Properly restrain children 12 years old and
under in a rear seating position whenever
possible. See
Seatbelts (page 37).

Expedition (TB8) Canada/United States of America, enUSA, Edition date: 201907, Third-Printing- SeatbeltsE142590

1. Buckle the combination lap and
shoulder belt.
2. Grasp the shoulder portion and pull downward until you pull the entire belt
out. As the belt retracts, you will hear
a clicking sound. This indicates the
seatbelt is now in the automatic
locking mode.
Rear Outermost Inflatable Seatbelts
(Second Row Only –If Equipped)1. Buckle the combination lap and
shoulder belt.
2. Grasp the lap portion of the belt and pull upward until you pull the entire
belt out. 3. Allow the belt to retract. As the belt
retracts, you will hear a clicking sound.
This indicates the seatbelt is now in the
automatic locking mode.
How to Disengage the Automatic
Locking Mode
Unbuckle the combination lap and
shoulder belt and allow it to retract
completely to disengage the automatic
locking mode and activate the vehicle
sensitive (emergency) locking mode.
Rear Inflatable Seatbelt (If Equipped) WARNING:
Do not attempt to
service, repair, or modify the
supplementary restraint system or
associated components. Failure to
follow this instruction could result in
personal injury or death.
The rear inflatable seatbelts are in the
shoulder portion of the seatbelts of the
second-row outermost seating positions.
Note: The rear inflatable seatbelts are
compatible with most infant and child
safety car seats and belt positioning booster
seats when you properly install them. This
is because they are designed to fill with a
cooled gas at a lower pressure and at a
slower rate than traditional airbags. After
inflation, the shoulder portion of the
seatbelt remains cool to the touch.
The rear inflatable seatbelt consists of the
following:
• An inflatable bag in the shoulder
seatbelt webbing.
• Lap seatbelt webbing with automatic
locking mode.
41
Expedition (TB8) Canada/United States of America, enUSA, Edition date: 201907, Third-Printing- SeatbeltsE142591 E146363

•
The same warning light, electronic
control and diagnostic unit as used for
the front seatbelts.
• Impact sensors in various parts of the
vehicle.
How does the rear inflatable seatbelt
system work? WARNING: If a supplementary
restraint system component has
deployed, it will not function again. Have
the system and associated components
inspected as soon as possible. Failure to
follow this instruction could result in
personal injury or death.
The rear inflatable seatbelts function like
standard restraints in everyday usage. During a crash of sufficient force, the
inflatable belt inflates from inside the
webbing. The fully inflated seatbelt's increased
diameter more effectively holds the
occupant in the appropriate seating
position, and spreads crash forces over
more area of the body than regular
seatbelts. This helps reduce pressure on
the chest and helps control head and neck
motion for passengers.
The rear inflatable seatbelts are designed
to inflate in frontal or near-frontal crashes,
side impact crashes and rollovers. The fact
that the rear inflatable seatbelt did not
inflate in a crash does not mean that
something is wrong with the system.
Rather, it means the forces were not of the
type sufficient to cause activation.
SEATBELT HEIGHT
ADJUSTMENT
WARNING:
Position the seatbelt
height adjuster so that the belt rests
across the middle of your shoulder.
Failure to adjust the seatbelt properly
could reduce the effectiveness of the
seatbelt and increase the risk of injury in
a crash.
42
Expedition (TB8) Canada/United States of America, enUSA, Edition date: 201907, Third-Printing- SeatbeltsE146364 E146365

To adjust the shoulder belt height, squeeze
the button and slide the height adjuster up
or down. Release the button and pull down
on the height adjuster to make sure it is
locked in place.

CHILD RESTRAINT AND
SEATBELT MAINTENANCE
Inspect the vehicle seatbelts and child
safety seat systems periodically to make
sure they work properly and are not
damaged. Inspect the vehicle and child
restraint seatbelts to make sure there are
no nicks, tears or cuts. Replace if
necessary. All vehicle seatbelt assemblies,
including retractors, buckles, front seatbelt buckle assemblies, buckle support
assemblies (slide bar-if equipped),
shoulder belt height adjusters (if
equipped), shoulder belt guide on seat
backrest (if equipped), child safety seat
LATCH and tether anchors, and attaching
hardware, should be inspected after a
crash. Read the child restraint
manufacturer's instructions for additional
inspection and maintenance information
specific to the child restraint.
We recommend that all seatbelt
assemblies in use in vehicles involved in a
crash be replaced. However, if the crash
was minor and an authorized dealer finds
that the belts do not show damage and
continue to operate properly, they do not
need to be replaced. Seatbelt assemblies
not in use during a crash should also be
inspected and replaced if either damage
or improper operation is noted.
Properly care for seatbelts. See Vehicle
Care (page 343).
SEATBELT EXTENSIONS WARNING:
Persons who fit into
the vehicle's seatbelt should not use an
extension. Unnecessary use could result
in serious personal injury in the event of
a crash. WARNING:
Only use extensions
provided free of charge by our dealers.
The dealer will provide an extension
designed specifically for this vehicle,
model year and seating position. The use
of an extension intended for another
vehicle, model year or seating position
may not offer you the full protection of
your vehicle's seatbelt restraint system. WARNING:
Never use seatbelt
extensions to install child restraints.
45
Expedition (TB8) Canada/United States of America, enUSA, Edition date: 201907, Third-Printing- Seatbelts

WARNING: Do not use a seatbelt
extension with an inflatable seatbelt. WARNING:
Do not use extensions
to change the way the seatbelt fits
across the torso, over the lap or to make
the seatbelt buckle easier to reach.
If, because of body size or driving position,
it is not possible to properly fasten the
seatbelt over your lap and shoulder, an
extension that is compatible with the
seatbelts is available free of charge from
our dealers. Only use our seatbelt
extensions made by the original equipment
seatbelt manufacturer with our seatbelts.
Ask your authorized dealer if your extension
is compatible with your vehicle restraint
system.

Expedition (TB8) Canada/United States of America, enUSA, Edition date: 201907, Third-Printing- Seatbelts

This system provides an improved overall
level of frontal crash protection to front
seat occupants and is designed to help
further reduce the risk of airbag-related
injuries. The system analyzes different
occupant conditions and crash severity
before activating the appropriate safety
devices to help better protect occupants
in a variety of frontal crash situations.
Your vehicle's Personal Safety System
consists of:
•
Driver and passenger dual-stage airbag
supplemental restraints.
• Front seat outermost seatbelts with
pretensioners, energy management
retractors and seatbelt usage sensors.
• Driver seat position sensor.
• Front passenger sensing system.
• Passenger airbag off and on indicators.
• Front crash severity sensors.
• Restraints control module with impact
and safing sensors.
• Restraint system warning light and
tone.
• The electrical wiring for the airbags,
crash sensors, seatbelt pretensioners,
front seatbelt usage sensors, driver
seat position sensor, front passenger
sensing system and indicator lights.
How Does the Personal Safety
System Work?
The Personal Safety System can adapt the
deployment strategy of the safety devices
according to crash severity and occupant
conditions. A collection of crash and
occupant sensors provides information to
the restraints control module. During a
crash, the restraints control module may
deploy the seatbelt pretensioners, one or
both stages of the dual-stage airbags
based on crash severity and occupant
conditions.
