Front safety belt pretensioners
The safety belt pretensioners at the front outboard seating positions are
designed to tighten the safety belts firmly against the occupant’s body
during frontal collisions and in side collisions. This helps increase the
effectiveness of the safety belts. In frontal collisions, the safety belt
pretensioners can be activated alone or, if the collision is of sufficient
severity, together with the front airbags.
Front safety belt energy management retractors
The front outboard safety belt energy management retractors allow
webbing to be pulled out of the retractor in a gradual and controlled
manner in response to the occupant’s forward momentum. This helps
reduce the risk of force-related injuries to the occupant’s chest by
limiting the load on the occupant. Refer toEnergy management feature
section in this chapter.
Determining if the Personal Safety Systemis operational
The Personal Safety Systemuses a warning light in the instrument
cluster or a back-up tone to indicate the condition of the system. Refer
to theWarning light and chimessection in theInstrument cluster
chapter. Routine maintenance of the Personal Safety Systemis not
required.
The Restraints control module (RCM) monitors its own internal circuits
and the circuits for the airbag supplemental restraints, crash sensor(s),
safety belt pretensioners, front safety belt buckle sensors, front
passenger sensing system, and the driver seat position sensor. In
addition, the RCM also monitors the restraints warning light in the
instrument cluster. A difficulty with the system is indicated by one or
more of the following.
•The warning light will either flash or stay lit.
•The warning 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 warning light are repaired.
If any of these things happen, even intermittently, have the Personal
Safety Systemserviced at an authorized dealer immediately. Unless
serviced, the system may not function properly in the event of a
collision.

Safety restraints precautions
WARNING:Always drive and ride with your seatback upright
and the lap belt snug and low across the hips.
WARNING:To reduce the risk of injury, make sure children sit
in a rear seating position where they can 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 collision.
WARNING:All occupants of the vehicle, including the driver,
should always properly wear their safety belts, even when an
airbag supplemental restraint system (SRS) is provided.
WARNING:It is extremely dangerous to ride in a cargo area,
inside or outside of a vehicle. In a collision, 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 safety belts. Be sure everyone in your vehicle is in a
seat and using a safety belt properly.
WARNING:In a rollover crash, an unbelted person is
significantly more likely to die than a person wearing a safety
belt.
WARNING:Each seating position in your vehicle has a specific
safety belt assembly which is made up of one buckle and one
tongue that are designed to be used as a pair. 1) Use the shoulder belt
on the outside shoulder only. Never wear the shoulder belt under the
arm. 2) Never swing the safety belt around your neck over the inside
shoulder. 3) Never use a single belt for more than one person.
WARNING:When possible, all children 12 years old and under
should be properly restrained in a rear seating position.

Reasons given... Consider...
“Traffic is light”Nearly 1 of 2 deaths occur in
single-vehicle crashes,many when
no other vehicles are around.
“Belts wrinkle my clothes” Possibly, but a serious crash can do
much more than wrinkle your clothes,
particularly if you are unbelted.
“The people I’m with don’t
wear belts”Set the example, teen deaths occur 4
times more often in vehicles with
TWO or MORE people. Children and
younger brothers/sisters imitate
behavior they see.
“I have an airbag” Airbags offer greater protection when
used with safety belts. Frontal airbags
are not designed to inflate in rear and
side crashes or rollovers.
“I’d rather be thrown clear” Not a good idea.Peoplewho are
ejected are 40 times more likely
to DIE.Safety belts help prevent
ejection, WE CAN’T “PICK OUR
CRASH”.
WARNING:Do not sit on top of a buckled safety belt or insert a
latchplate into the buckle to avoid the Belt-Minderchime. To
do so may adversely affect the performance of the vehicle’s air bag
system.

1. Turn the ignition switch to the on position. DO NOT START THE
ENGINE.
2. Wait until the safety belt warning light turns off (Approximately one
minute).
•Step 3 must be completed within 50 seconds after the safety belt
warning light turns off.
3. For the seating position being disabled, buckle then unbuckle the
safety belt nine times at a moderate speed, ending in the unbuckled
state. Step 3 must be completed within 50 seconds after the safety belt
warning light turns off.
•After Step 3, the restraint system warning light (airbag light) will be
turned on for three seconds.
4. Within approximately seven seconds of the light turning off, buckle
then unbuckle the safety belt.
•This will disable the Belt-Minderfeature for that seating position if it
is currently enabled. As confirmation, the restraint system warning
light will flash four times per second for three seconds.
•This will enable the Belt-Minderfeature for that seating position if it
is currently disabled. As confirmation, the restraint system warning
light will flash four times per second for three seconds, followed by
three seconds with the light off, then followed by the restraint system
warning light flashing four times per second for three seconds again.

AIRBAG SUPPLEMENTAL RESTRAINT SYSTEM (SRS)
Important SRS precautions
The SRS is designed to work with
the safety belt 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.
WARNING:All occupants of the vehicle, including the driver,
should always properly wear their safety belts, even when an air
bag supplemental restraint system (SRS) is provided.
WARNING:When possible, all children 12 years old and under
should be properly restrained in a rear seating position.
WARNING:The National Highway Traffic Safety Administration
(NHTSA) recommends a minimum distance of at least 10 inches
(25 cm) between an occupant’s chest and the driver airbag module.

WARNING:Never place your arm over the air bag module as a
deploying air bag can result in serious arm fractures or other
injuries.
WARNING:Ford Motor Company recommends that an
authorized dealer inspect all steering column assemblies in use
in vehicles involved in a collision. Failure to inspect and if necessary
replace the steering column assembly could result in severe injury or
death in the event of a collision.
WARNING:Do not attempt to service, repair, or modify the
steering column, its adaptive module, or its fuses. See your
authorized dealer.
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.
WARNING: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.
WARNING:Do not attempt to service, repair, or modify the
airbag supplemental restraint systems or its fuses. See your
authorized dealer.
WARNING:The front passenger airbag is not designed to offer
protection to an occupant in the center front seating position.
WARNING: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 airbag system,
increasing the risk of injury. Do not modify the front end of the
vehicle.

Children and airbags
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.
WARNING:Airbags can kill
or injure a child in a child
seat.NEVERplace a rear-facing
child seat in front of an active
airbag. If you must use a
forward-facing child seat in the
front seat, move the seat all the
way back.
WARNING:Front seating positions only: If seating two adults
and a child, Ford recommends properly restraining the child in
the center front seating position, but only if doing so will not interfere
with driving the vehicle. This arrangement provides lap and shoulder
belt and airbag protection for adult occupants and an attachment
method for a child restraint. If the child seat interferes with driving the
vehicle and the child restraint is forward-facing, the child may be
restrained in the passenger seat. Move the seat as far rearward as
possible to minimize the likelihood of interaction with the front
passenger airbag. Never place a rear-facing child seat in front of an
active airbag. All occupants of the vehicle should always properly wear
their safety belts. Ensure the child is properly restrained in an
appropriate child seat or with the use of a booster.

How does the airbag supplemental restraint system work?
The airbag SRS is designed to
activate when the vehicle sustains
longitudinal deceleration sufficient
to cause the sensors to close an
electrical circuit that initiates airbag
inflation.
The fact that the airbags 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. 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.
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 (e.g., 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, swelling or temporary
hearing loss. 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.

The SRS consists of the following items:
•Driver and passenger airbag modules (which include the inflators and
airbags)
•safety belt pretensioners
•Front passenger sensing system
•“Passenger airbag off” or “pass airbag off” indicator lamp. Refer to
Front passenger sensing systemlater in this chapter.
•Driver and passenger side airbags
•One or more impact and safing sensors
•A readiness light and tone
•A diagnostic module
•The electrical wiring which connects the components
The diagnostic module monitors its own internal circuits as well as the
supplemental airbag electrical system wiring (including the impact
sensors), the system wiring, the airbag system readiness light, the airbag
back up power and the airbag ignitors.
WARNING:Several air bag system components get hot after
inflation. Do not touch them after inflation.
WARNING: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.
WARNING:If the safety belt pretensioners deploy in an
accident, they will not function again ( belt will not extract or
retract) and must be replaced immediately. Failure to replace the
retractor assemblies will increase the risk of injury.
Front passenger sensing system
The front passenger sensing system is designed to meet the regulatory
requirements of Federal Motor Vehicle Safety Standard (FMVSS) 208
and is designed to disable (will not inflate) the front passenger’s frontal
airbag under certain conditions.

Owners Guide(own2002), 2nd Printing
USA(fus)
Seating and Safety Restraints

The front passenger sensing system works with sensors that are part of
the front passenger’s seat and safety belt. The sensors are designed to
detect the presence of a properly seated occupant and determine if the
front passenger’s frontal airbag should be enabled (may inflate) or
disabled (will not inflate).
The front passenger sensing system will disable (will not inflate) the
front passenger’s frontal airbag if:
•the front passenger seat is unoccupied, or has small/medium objects in
the front seat,
•the system determines that an infant is present in a rear-facing infant
seat that is installed according to the manufacturer’s instructions,
•the system determines that a small child is present in a forward-facing
child restraint that is installed according to the manufacturer’s
instructions,
•the system determines that a small child is present in a booster seat,
•a front passenger takes his/her weight off of the seat for a period of
time,
For side airbag equipped vehicles, the front passenger sensing system
will turn off the passenger seat side airbag if:
•the seat is empty and safety belt is unbuckled.
The front passenger sensing system
uses apassenger airbag offor
pass airbag offindicator which will
illuminate and stay lit to remind you
that the front passenger frontal
airbag is disabled. The indicator
lamp is located on the instrument panel to the right of the radio over the
glove box.
Note: The indicator lamp will illuminate for a short period of time when
the ignition is turned to the on position to confirm it is functional.
When the front passenger seat is not occupied (empty seat) or in the
event that the front passenger frontal airbag is enabled (may inflate), the
indicator lamp will be unlit.
The front passenger sensing system is designed to disable (will not
inflate) the front passenger’s frontal airbag when a rear facing infant
seat, a forward-facing child restraint, or a booster seat is detected.
•When the front passenger sensing system disables (will not inflate)
the front passenger frontal airbag, the indicator lamp will illuminate
and stay lit to remind you that the front passenger frontal airbag is
disabled.
