PRINCIPLE OF OPERATION
WARNING: Always drive and ride
with your seatback upright and the lap
belt snug and low across the hips. WARNING:
Children must always
be properly restrained. WARNING:
Never let a passenger
hold a child on his or her lap while the
vehicle is moving. The passenger cannot
protect the child from injury in a crash. 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:
It is extremely
dangerous to ride in a cargo area, inside
or outside of a vehicle. In a crash, people
riding in these areas are more likely to be
seriously injured or killed. Do not allow
people to ride in any area of your vehicle
that is not equipped with seats and
seatbelts. Make sure everyone in your
vehicle is in a seat and properly using a
seatbelt. Failure to follow this warning
could result in serious personal injury or
death. WARNING:
In a rollover crash, an
unbelted person is significantly more
likely to die than a person wearing a
seatbelt. WARNING:
Each seating position
in your vehicle has a specific seatbelt
assembly made up of one buckle and
one tongue designed to be used as a pair.
Use the shoulder belt on the outside
shoulder only. Never wear the shoulder
belt under the arm. Never use a single
seatbelt for more than one person. 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:
Seatbelts and seats
may be hot in a vehicle that is in the
sunshine. The hot seatbelts or seats may
burn a small child. Check seat covers and
buckles before you place a child
anywhere near them.
All seating positions in your vehicle have
lap and shoulder seatbelts. All occupants
of the vehicle should always properly wear
their seatbelts, even when an airbag
supplemental restraint system is provided.
The seatbelt system consists of:
• Lap and shoulder seatbelts.
• Shoulder seatbelt with automatic
locking mode, (except driver seatbelt
and rear inflatable seatbelt).
• Height adjuster at the front outboard
seating positions.
• Seatbelt pretensioner at the front
outboard seating positions.
• Belt tension sensor at the front
outboard passenger seating position. •
Seatbelt warning light and chime.
39
Expedition (TB8) Canada/United States of America, enUSA, First-Printing SeatbeltsE71880

•
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 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.

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.

™

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 56).
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.

Expedition (TB8) Canada/United States of America, enUSA, First-Printing Supplementary Restraints System E151127 E67017

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 seat backrest 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.
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 seat backrest,
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.
If you think that the state of the passenger
airbag status indicator lamp is incorrect,
check for the following:
• Objects lodged underneath the seat.
• Objects between the seat cushion and
the center console.
• Objects hanging off the seat backrest.
• Objects stowed in the seat backrest
map pocket.
• Objects placed on the occupant's lap.
• Cargo interference with the seat.
53
Expedition (TB8) Canada/United States of America, enUSA, First-Printing Supplementary Restraints System

•
Other passengers pushing or pulling on
the seat.
• Rear passenger feet and knees resting
or pushing on the seat.
The conditions listed above may cause the
weight of a properly seated occupant to
be incorrectly interpreted by the front
passenger sensing system. The person in
the front passenger seat may appear
heavier or lighter due to the conditions
described in the previous list. Make sure the front passenger
sensing system is operating
properly. See Crash Sensors
and Airbag Indicator (page 56).
If the airbag readiness light is lit, do the
following:
The driver and adult passengers should
check for objects lodged underneath the
front passenger seat or cargo interfering
with the seat.
If objects are lodged or cargo is interfering
with the seat, take the following steps to
remove the obstruction:
• Pull your vehicle over.
• Switch your vehicle off.
• Driver or adult passengers should
check for any objects lodged
underneath the front passenger seat
or cargo interfering with the seat.
• Remove the obstruction(s) (if found).
• Restart your vehicle.
• Wait at least two minutes and verify
that the airbag readiness light in the
instrument cluster is no longer
illuminated.
• If the airbag readiness light in the
instrument cluster remains illuminated,
this may or may not be a problem due
to the front passenger sensing system. Do not attempt to repair or service the
system. Take your vehicle immediately to
an authorized dealer.
If it is necessary to modify an advanced
front airbag system to accommodate a
person with disabilities, contact your
Customer Relationship Center.
SIDE AIRBAGS
WARNING:
Do not place objects
or mount equipment on or near the
airbag cover, on the side of the front or
rear seatbacks, or in areas that may
come into contact with a deploying
airbag. Failure to follow these
instructions may increase the risk of
personal injury in the event of a crash. WARNING:
Do not use accessory
seat covers. The use of accessory seat
covers may prevent the deployment of
the side airbags and increase the risk of
injury in an accident. WARNING:
Do not lean your head
on the door. The side airbag could injure
you as it deploys from the side of the
seatback. 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:
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.
