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 return to the
vehicle sensitive (emergency) locking mode.
After any vehicle collision, the combination lap and shoulder belt
system at all passenger seating positions must be checked by a
qualified technician to verify that the “ automatic locking retractor ”
feature for child seats is still functioning properly, in addition to other
checks for proper seat belt system function.
BELT AND RETRACTOR ASSEMBLY MUST BE REPLACED if
the safety belt assembly “ automatic locking retractor ” feature or
any other safety belt function is not operating properly. In addition, all
safety belts should be checked for proper function. Failure to replace
the belt and retractor assembly could increase the risk of injury in
collisions.
Safety belt pretensioner
Your vehicle is equipped with safety belt pretensioners at the driver and
right front passenger seating positions.
The safety belt pretensioner removes some slack from the safety belt
system at the start of a crash. The safety belt pretensioner uses the
same crash sensor system as the front airbags and Safety Canopy

system. When the safety belt pretensioner deploys, the lap and shoulder
belt are tightened.
When the Safety Canopy
system and/or the front airbags are activated,
the safety belt pretensioners for the driver and right front passenger
seating positions will be activated when the respective seatbelt is
properly buckled.
The driver and the right front passenger seat belt system
(including retractors, buckles and height adjusters) must be
replaced if the vehicle is involved in a collision that results in
deployment of front air bags or Safety Canopy
and safety belt
pretensioners.
Refer to the Safety belt maintenance section in this chapter.

Always transport children 12 years old and under in the back
seat and always properly use appropriate child restraints.
The National Highway Traffic Safety Administration (NHTSA)
recommends a minimum distance of at least 25 cm (10 inches)
between an occupant ’ s chest and the driver air bag module.
Never place your arm over the air bag module as a deploying air
bag can result in serious arm fractures or other injuries.
To properly position yourself away from the air bag:
• 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.
Do not put anything on or over the air bag module. Placing
objects on or over the air bag inflation area may cause those
objects to be propelled by the air bag into your face and torso causing
serious injury.
Do not attempt to service, repair, or modify the air bag
supplemental restraint systems or its fuses. See your Ford or
Lincoln Mercury dealer.
The front passenger air bag is not designed to offer protection to
an occupant in the center front seating position.
Modifying or adding equipment to the front end of the vehicle
(including frame, bumper, front end body structure and tow
hooks) may affect the performance of the air bag system, increasing
the risk of injury. Do not modify the front end of the vehicle.
Additional equipment may affect the performance of the air bag
sensors increasing the risk of injury. Please refer to the Body
Builders Layout Book for instructions about the appropriate installation
of additional equipment.

Children and air bags
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 collision.
Air bags can kill or injure a
child in a child seat.
NEVER place a rear-facing child
seat in front of an active air bag. If
you must use a forward-facing
child seat in the front seat, move
the seat all the way back.
How does the air bag supplemental restraint system work?
The air bag SRS is designed to
activate when the vehicle sustains
longitudinal deceleration sufficient
to cause the sensors to close an
electrical circuit that initiates air
bag inflation.
The fact that the air bags did not
inflate in a collision does not mean
that something is wrong with the
system. Rather, it means the forces
were not of the type sufficient to
cause activation. The driver and passenger airbags are designed to inflate
in frontal and near-frontal collisions, not rollover, side-impact, or
rear-impacts unless the collision causes sufficient longitudinal
deceleration.

USA English (fus) Seating and Safety Restraints

The air bags inflate and deflate
rapidly upon activation. After air bag
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 (e.g., baking
soda) that result from the
combustion process that inflates the
air bag. 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 air bag may also cause abrasions, swelling or temporary
hearing loss. Because air bags 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 air bag deployment. Thus, it is extremely important that occupants be
properly restrained as far away from the air bag module as possible while
maintaining vehicle control.
Several air bag system components get hot after inflation. Do not
touch them after inflation.
If the air bag has deployed, the air bag will not function
again and must be replaced immediately. If the air bag is not
replaced, the unrepaired area will increase the risk of injury in a
collision.
The SRS consists of:
• driver and passenger air bag modules (which include the inflators and
air bags),
• one or more impact and safing sensors and diagnostic monitor (RCM),
• a readiness light and tone
• the electrical wiring which connects the components.
The RCM (restraints control module) monitors its own internal circuits
and the supplemental air bag electrical system wiring (including the
2004 Navigator (nav)
Owners Guide (post-2002-fmt)
USA English (fus)Seating and Safety Restraints
198

impact sensors, the system wiring, the air bag system readiness light, the
air bag back up power and the air bag ignitors).
Determining if the system is operational
The SRS uses a readiness light in the instrument cluster or a tone to
indicate the condition of the system. Refer to Air bag readiness section
in the Instrument cluster chapter. Routine maintenance of the air bag is
not required.
A difficulty with the system is indicated by one or more of the following:
• The readiness light will either
flash or stay lit.
• The readiness light will not
illuminate immediately after ignition is turned on.
• A series of five beeps will be heard. The tone pattern will repeat
periodically until the problem and/or light are repaired.
If any of these things happen, even intermittently, have the SRS serviced
at your dealership or by a qualified technician immediately. Unless
serviced, the system may not function properly in the event of a
collision.
Safety Canopy  system
Do not place objects or
mount equipment on or
near the headliner at the siderail
that may come into contact with a
deploying Safety Canopy
. Failure
to follow these instructions may
increase the risk of personal injury
in the event of a collision.
Do not lean your head on the door. The Safety Canopy
could
injure you as it deploys from the headliner.

• Two crash sensors mounted in the front doors (one on each side).
• Two crash sensors located at the c-pillar behind the rear doors (one
on each side).
• Rollover sensor in the restraints control module (RCM).
The Safety Canopy
system, in combination with seat belts, can help
reduce the risk of severe injuries in the event of a significant side impact
collision or rollover event.
Children 12 years old and under should always be properly restrained in
the second or third row seats. The Safety Canopy
will not interfere
with children restrained using a properly installed child or booster seat
because it is designed to inflate downward from the headliner above the
doors along the side window opening.
The Safety Canopy
system is designed to activate when the vehicle
sustains lateral deceleration sufficient to cause the side crash sensor to
close an electrical circuit that initiates Safety Canopy
inflation or when
a certain likelihood of a rollover event is detected by the rollover sensor.
The Safety Canopy
is mounted to roof side-rail sheet metal, behind the
headliner, above the first and second row seats. In certain lateral
collisions or rollover events, the Safety Canopy
system will be
activated, regardless of which seats are occupied. In certain rollover
events, the Safety Canopy
on both sides of the vehicle will be inflated,
regardless of which seats are occupied. The Safety Canopy
is designed
to inflate between the side window area and occupants to further
enhance protection provided in side impact collisions and rollover events.
The fact that the Safety Canopy
did not activate in a collision does not
mean that something is wrong with the system. Rather, it means the
forces were not of the type sufficient to cause activation. The Safety
Canopy
is designed to inflate in certain side impact collisions or
rollover events, not in rear impact, frontal or near-frontal collisions,
unless the collision causes sufficient lateral deceleration or rollover
likelihood.

Do not alter or modify your vehicle ’ s suspension or steering; the
resulting changes to the vehicle ’ s handling can adversely affect
the Roll Stability Control system. Also, do not install a stereo
loudspeaker near the front center console or under either front
seat. The speaker vibrations can adversely affect the Roll
Stability Control sensors located in this area.
Note: Pressing the Roll Stability Control button will disable the Roll
Stability Control.
Aggressive driving in any road conditions can cause you to lose
control of your vehicle increasing the risk of severe personal
injury or property damage. The occurrence of an Roll Stability Control
event is an indication that at least some of the tires have exceeded
their ability to grip the road; this may lead to an increased risk of loss
of vehicle control, vehicle rollover, personal injury and death. If you
experience a severe road event, SLOW DOWN.
AUTOMATIC TRANSMISSION OPERATION
Brake-shift interlock
This vehicle is equipped with a brake-shift interlock feature that prevents
the gearshift lever from being moved from P (Park) when the ignition is
in the ON position unless brake pedal is depressed.
If you cannot move the gearshift lever out of P (Park) with ignition in
the ON position and the brake pedal depressed, it is possible that a fuse
has blown or the vehicle ’ s brakelamps are not operating properly. Refer
to Fuses and relays in the Roadside emergencies chapter.
If the fuse is not blown, perform the following procedure:
1. Apply the parking brake, turn the ignition to LOCK, then remove the
key.

The system is not effective at speeds greater than 10 km/h (6 mph) and
may not detect certain angular or moving objects.
The system detects obstacles up to
a maximum range of six meters (20
ft.) behind the rear bumper with a
decreased coverage area at the
outer corners of the bumper, (refer
to the figures for approximate zone
coverage areas). As you move closer
to the obstacle, the rate of the tone
increases. When the distance to the
obstacle is less than 45.0 cm (18
in.), the tone will sound
continuously. If the system detects
an object that is approaching the
vehicle at such as rate that rapid
braking is required, a very high rate
tone will sound. If this tone is heard
while reversing, the driver is advised
to slow down immediately until the
tone either changes to a slower rate
or stops.
While receiving a warning the radio
volume will be reduced to a predetermined level. After the warning goes
away, the radio will return to the previous volume. The radio volume may
be overridden using the radio volume control.
The extended rear park assist is automatically enabled when the gear
selector is placed in R (Reverse) and the ignition is ON. A park assist
control in the message center allows the driver to disable the extended
rear park aid only when the ignition is ON, and the gear selector is in R
(Reverse).
Always keep the sensors (located on the rear bumper/fascia) free
from snow, ice and large accumulations of dirt (do not clean the
sensors with sharp objects). These elements may cause the
system to operate inaccurately.
If the vehicle sustains damage to the rear bumper/fascia, leaving
it misaligned or bent, the sensing zone may be altered causing
inaccurate measurement of obstacles or false alarms.
