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.
38
Expedition (TB8) Canada/United States of America, enUSA, Edition date: 201708, 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.
39
Expedition (TB8) Canada/United States of America, enUSA, Edition date: 201708, 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.

SEATBELT REMINDER
Belt-Minder™
This feature supplements the seatbelt
warning function by providing additional
reminders that intermittently sound a tone
and illuminate the seatbelt warning light
when you are in the driver seat or you have
a front seat passenger and a seatbelt is
unbuckled. The system uses information from the
front passenger sensing system to
determine if a front seat passenger is
present and therefore potentially in need
of a warning. To avoid activating the
Belt-Minder feature for objects you place
in the front passenger seat, only the front
seat passengers receive warnings as
determined by the front passenger sensing
system.
If the Belt-Minder warnings expire
(warnings for about five minutes) for one
passenger (driver or front passenger), the
other passenger can still cause the
Belt-Minder feature to turn on.

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 344). SEATBELT EXTENSION 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 Ford Motor
Company 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. WARNING:
Do not use a seatbelt
extension with an inflatable seatbelt. WARNING:
Do not use extensions
to change the fit of the belt 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
Ford Motor Company dealers. Only Ford
seatbelt extensions made by the original
equipment seatbelts manufacturer should
be used with Ford seatbelts. Ask your
authorized dealer if your extension is
compatible with your Ford vehicle restraint
system.

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 (first row only) and seatbelt
usage sensors.
• Driver seat position sensor.
• Front passenger sensing system.
• Passenger airbag off and on indicator
lamp.
• 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.

PRINCIPLE OF OPERATION
WARNING: Airbags do not inflate
slowly or gently, and the risk of injury
from a deploying airbag is the greatest
close to the trim covering the airbag
module. WARNING:
All occupants of your
vehicle, including the driver, should
always properly wear their seatbelts,
even when an airbag supplemental
restraint system is provided. Failure to
properly wear your seatbelt could
seriously increase the risk of injury or
death. WARNING:
Even with advanced
restraints systems, properly restrain
children 12 and under in a rear seating
position. Failure to follow this could
seriously increase the risk of injury or
death. WARNING: Do not place your arms
on the airbag cover or through the
steering wheel. Failure to follow this
instruction could result in personal injury. WARNING:
Keep the areas in front
of the airbags free from obstruction. Do
not affix anything to or over the airbag
covers. Objects could become projectiles
during airbag deployment or in a sudden
stop. Failure to follow this instruction
could result in personal injury or death. WARNING:
Airbags can kill or
injure a child in a child restraint. Never
place a rear-facing child restraint in front
of an active airbag. If you must use a
forward-facing child restraint in the front
seat, move the seat upon which the child
restraint is installed all the way back. 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. WARNING:
Several airbag system
components get hot after inflation. To
reduce the risk of injury, do not touch
them after inflation. 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 airbags are a supplemental restraint
system and are designed to work with the
seatbelts to help protect the driver and
right front passenger from certain upper
body injuries. Airbags do not inflate slowly;
there is a risk of injury from a deploying
airbag.
Note: You will hear a loud bang and see a
cloud of harmless powdery residue if an
airbag deploys. This is normal.
The airbags inflate and deflate rapidly
upon activation. After airbag deployment,
it is normal to notice a smoke-like, powdery
residue or smell the burnt propellant. This
may consist of cornstarch, talcum powder
(to lubricate the bag) or sodium
compounds (for example, baking soda)
that result from the combustion process
that inflates the airbag. Small amounts of
sodium hydroxide may be present which
may irritate the skin and eyes, but none of
the residue is toxic.
44
Expedition (TB8) Canada/United States of America, enUSA, Edition date: 201708, Third-Printing- Supplementary Restraints System

While the system is designed to help
reduce serious injuries, contact with a
deploying airbag may also cause abrasions
or swelling. Temporary hearing loss is also
a possibility as a result of the noise
associated with a deploying airbag.
Because airbags must inflate rapidly and
with considerable force, there is the risk of
death or serious injuries such as fractures,
facial and eye injuries or internal injuries,
particularly to occupants who are not
properly restrained or are otherwise out of
position at the time of airbag deployment.
Thus, it is extremely important that
occupants be properly restrained as far
away from the airbag module as possible
while maintaining vehicle control.
Routine maintenance of the airbags is not
required.
DRIVER AND PASSENGER
AIRBAGS
WARNING: Do not place your arms
on the airbag cover or through the
steering wheel. Failure to follow this
instruction could result in personal injury. WARNING: Keep the areas in front
of the airbags free from obstruction. Do
not affix anything to or over the airbag
covers. Objects could become projectiles
during airbag deployment or in a sudden
stop. Failure to follow this instruction
could result in personal injury or death. WARNING:
Airbags can kill or
injure a child in a child restraint. Never
place a rear-facing child restraint in front
of an active airbag. If you must use a
forward-facing child restraint in the front
seat, move the seat upon which the child
restraint is installed all the way back. The driver and passenger front airbags will
deploy during significant frontal and near
frontal crashes.
The driver and passenger front airbag
system consists of:
•
Driver and passenger airbag modules.
• Front passenger sensing system. · Crash sensors and monitoring
system with readiness indicator.
See Crash Sensors and Airbag
Indicator
(page 51).
Proper Driver and Front Passenger
Seating Adjustment WARNING:
National Highway
Traffic Safety Administration (NHTSA)
recommends a minimum distance of at
least
10 in (25 cm) between an
occupant's chest and the driver airbag
module.
To properly position yourself away from
the airbag:
• Move your seat to the rear as far as you
can while still reaching the pedals
comfortably.
• Recline the seat slightly (one or two
degrees) from the upright position.
45
Expedition (TB8) Canada/United States of America, enUSA, Edition date: 201708, Third-Printing- Supplementary Restraints SystemE151127 E67017

After all occupants have adjusted their
seats and put on seatbelts, it is very
important that they continue to sit
properly. Properly seated occupants sit
upright, lean against the seat back, and
center themselves on the seat cushion,
with their feet comfortably extended on
the floor. Sitting improperly can increase
the chance of injury in a crash event. For
example, if an occupant slouches, lies
down, turns sideways, sits forward, leans
forward or sideways, or puts one or both
feet up, the chance of injury during a crash
greatly increases.
Children and Airbags
WARNING: Airbags can kill or
injure a child in a child restraint. Never
place a rear-facing child restraint in front
of an active airbag. If you must use a
forward-facing child restraint in the front
seat, move the seat upon which the child
restraint is installed all the way back. Children must always be properly
restrained. Accident statistics suggest that
children are safer when properly restrained
in the rear seating positions than in the
front seating position. Failure to follow
these instructions may increase the risk of
injury in a crash. FRONT PASSENGER SENSING
SYSTEM WARNING:
Even with advanced
restraints systems, properly restrain
children 12 and under in a rear seating
position. Failure to follow this could
seriously increase the risk of injury or
death. WARNING:
Sitting improperly, out
of position or with the seatback reclined
too far can take weight off the seat
cushion and affect the decision of the
passenger sensing system, resulting in
serious injury or death in the event of a
crash. Always sit upright against your
seat back, with your feet on the floor. WARNING:
Any alteration or
modification to the front passenger seat
may affect the performance of the front
passenger sensing system. This could
seriously increase the risk of injury or
death. The front passenger sensing system uses
a passenger airbag status indicator which
illuminates indicating that the front
passenger frontal airbag is either on
(enabled) or off (disabled). The indicator
lamp is in the center stack of the
instrument panel.
46
Expedition (TB8) Canada/United States of America, enUSA, Edition date: 201708, Third-Printing- Supplementary Restraints SystemE142846 E181984

Note:
When you first switch the ignition on,
the passenger airbag status indicator off
and on lamps illuminate for a short period
to confirm it is functional.
The front passenger sensing system is
designed to disable (will not inflate) the
front passenger frontal airbag under
certain conditions:
• The front passenger seat is
unoccupied.
• The system determines an infant is
present in a child restraint.
• A passenger takes their weight off of
the seat for a period of time.
• If there is a problem with the airbag
system or the passenger sensing
system.
Even with this technology, parents are
strongly encouraged to always properly
restrain children in the rear seat.
• When the front passenger sensing
system disables (will not inflate) the
front passenger frontal airbag, the
passenger airbag status indicator
illuminates the off lamp and stays lit
to remind you that the front passenger
frontal airbag is disabled.
• If you have installed the child restraint
and the passenger airbag status
indicator illuminates the on lamp, then
switch your vehicle off, remove the
child restraint from your vehicle and
reinstall the restraint following the
child restraint manufacturer's
instructions.
The front passenger sensing system works
with sensors that are part of the front
passenger seat and seatbelt. The sensors
are designed to detect the presence of a
properly seated occupant and determine
if the front passenger frontal airbag should
be enabled. •
When the front passenger sensing
system enables the front passenger
frontal airbag (may inflate), the
passenger airbag status indicator
illuminates the on lamp and remains
illuminated.
If a person of adult size is sitting in the front
passenger seat, but the passenger airbag
status indicator off lamp is lit, it is possible
that the person is not sitting properly in the
seat. If this happens:
• Switch your vehicle off and ask the
person to place the seatback in an
upright position.
• Have the person sit upright in the seat,
centered on the seat cushion, with the
person's legs comfortably extended.
• Restart your vehicle and have the
person remain in this position for about
two minutes. This allows the system
to detect that person and enable the
passenger frontal airbag.
• If the indicator off lamp remains lit
even after this, you should advise the
person to ride in the rear seat.
Note: When the passenger airbag status
indicator off lamp illuminates, the passenger
side airbag (seat mounted) may be disabled
to avoid the risk of airbag deployment
issues.
After all occupants have adjusted their
seats and put on seatbelts, it is very
important that they continue to sit
properly. A properly seated occupant sits
upright, leaning against the seatback, and
centered on the seat cushion, with their
feet comfortably extended on the floor.
Sitting improperly can increase the chance
of injury in a crash event. For example, if
an occupant slouches, lies down, turns
sideways, sits forward, leans forward or
sideways, or puts one or both feet up, the
chance of injury during a crash greatly
increases.
