REPLACEMENT PARTS
RECOMMENDATION
We have built your vehicle to the highest
standards using quality parts. We
recommend that you demand the use of
genuine Ford and Motorcraft parts whenever
your vehicle requires scheduled
maintenance or repair. You can clearly
identify genuine Ford and Motorcraft parts
by looking for the Ford, FoMoCo or
Motorcraft branding on the parts or their
packaging.
Scheduled Maintenance and
Mechanical Repairs
One of the best ways for you to make sure
that your vehicle provides years of service
is to have it maintained in line with our
recommendations using parts that conform
to the specifications detailed in this Owner’
s
Manual. Genuine Ford and Motorcraft parts
meet or exceed these specifications. Collision Repairs
We hope that you never experience a
collision, but accidents do happen. Genuine
Ford replacement collision parts meet our
stringent requirements for fit, finish, structural
integrity, corrosion protection and dent
resistance. During vehicle development we
validate that these parts deliver the intended
level of protection as a whole system. A
great way to know for sure you are getting
this level of protection is to use genuine Ford
replacement collision parts.
Warranty on Replacement Parts
Genuine Ford and Motorcraft replacement
parts are the only replacement parts that
benefit from a Lincoln Warranty. Damage
caused to your vehicle as a result of the
failure of non-Ford parts may not be covered
by the Lincoln Warranty. For additional
information, refer to the terms and conditions
of the Lincoln Warranty.
SPECIAL NOTICES
New Vehicle Limited Warranty
For a detailed description of what is covered
by your New Vehicle Limited Warranty, see
your warranty guide that is available online.
For more information, refer to our website
and download your copy of the warranty
guide.
Special Instructions
For your added safety, your vehicle is fitted
with sophisticated electronic controls.
WARNING: You risk death or serious
injury to yourself and others if you do not
follow the instruction highlighted by the
warning symbol. Failure to follow the
specific warnings and instructions could
result in personal injury.

Note:
The driver and front passenger
warnings switch on and off independently.
When you perform this procedure for one
seating position, do not buckle the other
position as this terminates the process.
Read Steps 1 - 4 before starting the
procedure.
Make sure that:
• You set the parking brake.
• The transmission is in park (P).
• The ignition is off.
• You close all vehicle doors.
• You unbuckle the driver and front
passenger seatbelts.
1. Switch the ignition on. Do not start the engine.
2. Wait until the seatbelt warning lamp turns
off (about one minute). After Step 2, wait
an additional five seconds before
proceeding with Step 3. Once you start
Step 3, you must complete the procedure
within 60 seconds. 3.
For the seating position you are switching
off, buckle then unbuckle the seatbelt
three times at a moderate speed, ending
in the unbuckled state. After Step 3, the
seatbelt warning lamp turns on.
4. When the seatbelt warning lamp is on, buckle then unbuckle the seatbelt. After
Step 4, the seatbelt warning lamp flashes
for confirmation.
• This switches the feature off if it is
currently on.
• This switches the feature on if it is
currently off.
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 396).

Navigator (TB9) Canada/United States of America, enUSA, First-Printing Seatbelts

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

The design and development of the Safety
Canopy included recommended testing
procedures that were developed by a group
of automotive safety experts known as the
Side Airbag Technical Working Group. These
recommended testing procedures help
reduce the risk of injuries related to the
deployment of side airbags (including the
Safety Canopy).
CRASH SENSORS AND AIRBAG
INDICATOR
WARNING: Modifying or adding
equipment to the front end of your vehicle
(including hood, bumper system, frame,
front end body structure, tow hooks and
hood pins) may affect the performance of
the airbag system, increasing the risk of
injury. Do not modify or add equipment to
the front end of your vehicle. Your vehicle has a collection of crash and
occupant sensors which provide information
to the restraints control module which
deploys (activates) the front seatbelt
pretensioners, the adaptive steering column,
driver airbag, passenger airbag, rear
inflatable belts, seat mounted side airbags,
and the Safety Canopy. Based on the type
of crash, the restraints control module will
deploy the appropriate safety devices.
The restraints control module also monitors
the readiness of the above safety devices
plus the crash and occupant sensors. The
readiness of the safety system is indicated
by a warning indicator light in the instrument
cluster or by a backup tone if the warning
light is not working. See Instrument Cluster
(page
127). Routine maintenance of the
airbag is not required.
A difficulty with the system is indicated by
one or more of the following: The readiness light will not
illuminate immediately after you
switch the ignition on.•
The readiness light either flashes or stays
lit.
• A series of five beeps will be heard. The
tone pattern will repeat periodically until
the problem, the light or both are
repaired.
If any of these things happen, even
intermittently, have the supplemental
restraint system serviced at an authorized
dealer immediately. Unless serviced, the
system may not function properly in the
event of a crash.
