Lincoln Navigator (2019 year). Manual — part 3

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).

Seatbelts

•

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.

E71880

•

E67017

•

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.

E142587

1. Insert the seatbelt tongue into the proper

buckle (the buckle closest to the direction
the tongue is coming from) until you hear

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.

E142590

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

42

Navigator (TB9) Canada/United States of America, enUSA, Edition date: 201808, First-Printing

Seatbelts

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 39).

How to Use the Automatic Locking Mode

Non-Inflatable Seatbelts

E142591

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)

E146363

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.

Seatbelts

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.

•

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.

E146364

44

Navigator (TB9) Canada/United States of America, enUSA, Edition date: 201808, First-Printing

Seatbelts

During a crash of sufficient force, the
inflatable belt inflates from inside the
webbing.

E146365

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.

E146191

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 378).

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.

48

Seatbelts

WARNING: Only use extensions

provided free of charge by Lincoln 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
Lincoln Motor Company dealers. Only Lincoln
seatbelt extensions made by the same
company which made the original equipment
seatbelts, should be used with Lincoln
seatbelts. Ask your authorized dealer if your
extension is compatible with your Lincoln
vehicle restraint system.

Seatbelts

The Personal Safety 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 is able to
analyze different occupant conditions and
crash severity before activating the
appropriate safety devices to help better
protect a range of occupants in a variety of
frontal crash situations.

The Vehicle 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.

•

Passenger 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 lamp 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 indicators.

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.

Personal Safety System™

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.

51

Navigator (TB9) Canada/United States of America, enUSA, Edition date: 201808, First-Printing

Supplementary Restraints System

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.

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.

E151127

The driver and passenger front airbags will
deploy during significant frontal and near
frontal crashes.

52

Navigator (TB9) Canada/United States of America, enUSA, Edition date: 201808, First-Printing

Supplementary Restraints System

The driver and passenger front airbag system
consists of:
•

Driver and passenger airbag modules.

•

Front passenger sensing system.

E67017

· Crash sensors and monitoring
system with readiness indicator.
See Crash Sensors and Airbag

Indicator (page 59).

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.

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.

E142846

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.

Supplementary Restraints System

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.

E181984

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.

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.
