Reasons given... Consider...
“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. People who 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-Minder  chime. To
do so may adversely affect the performance of the vehicle’s airbag
system.
Deactivating/activating the Belt-Minder  feature (Driver only)
Note: If you are using MyKey  , the Belt-Minder  cannot be disabled.
Also, if the Belt-Minder  has been previously disabled, it will be
re-enabled during the use of MyKey  . Refer to MyKey  in the Locks and
Security chapter.
The Belt-Minder  feature can be deactivated/activated by performing the
following procedure:
Before following the procedure, make sure that the following conditions
are met:
• the parking brake is set
• the gearshift is in P (Park)
• the ignition switch is in the off position
• all vehicle doors are closed
• the driver’s safety belt is unbuckled
• the parklamps/headlamps are in the off position
WARNING: While the design allows you to deactivate your
Belt-Minder  , this system is designed to improve your chances of
being safely belted and surviving an accident. We recommend you
leave the Belt-Minder  system activated for yourself and others who
may use the vehicle. To reduce the risk of injury, do not
deactivate/activate the Belt-Minder  feature while driving the vehicle.Seating and Safety Restraints

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.Seating and Safety Restraints

WARNING: Never place your arm over the airbag module as a
deploying airbag can result in serious arm fractures or other
injuries.
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 airbag module.
Placing objects on or over the airbag inflation area may cause
those objects to be propelled by the airbag 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. Contact your
authorized dealer as soon as possible.
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.
WARNING: Additional equipment such as snowplow equipment
may effect the performance of the airbag 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 airbags
For additional important safety information, read all information on
safety restraints in this guide.
Children must always be properly restrained. Failure to follow these
instructions may increase the risk of injury in a collision. Seating and Safety Restraints

WARNING: An infant in a rear-facing seat faces a high risk of
serious or fatal injuries from a deploying passenger airbag. Rear
facing infant seats should NEVER be placed in the front seats, unless
the passenger airbag is turned off. See Passenger airbag ON/OFF
switch.
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. Always properly restrain all occupants, including the
child in an appropriate child seat or booster.
How does the airbag supplemental restraint system work?
The airbag SRS is designed to
activate when the vehicle sustains
sufficient longitudinal deceleration.
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. Airbags are
designed to inflate in frontal and
near-frontal collisions, not rollover,
side-impact, or rear-impacts.Seating and Safety Restraints

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, it may also
cause minor 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.
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.
The SRS consists of:
• driver and passenger airbag modules (which include the inflators and
airbags),
• seat-mounted side airbags (if equipped) . Refer to Seat-mounted side
airbag system later in this chapter
• Safety Canopy  System (if equipped). Refer to Safety Canopy 
System later in this chapter. Seating and Safety Restraints

• one or more impact and safing sensors,
• a readiness light and tone
• and the electrical wiring which connects the components.
The diagnostic module monitors its own internal circuits and the
supplemental airbag electrical system wiring (including the impact
sensors), the system wiring, the airbag system readiness light, the airbag
backup power and the airbag ignitors.
Seat-mounted side airbag system (if equipped)
WARNING: Do not place objects or mount equipment on or
near the airbag cover on the side of the seatbacks of the front
seats or in front seat 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 collision.
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
airbag SRS, its fuses or the seat cover on a seat containing an
airbag. See an authorized dealer.
WARNING: All occupants of the vehicle should always wear
their safety belts even when an airbag SRS is provided.Seating and Safety Restraints

How does the side airbag system work?
The design and development of the
side airbag system 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.
The side airbag system consists of
the following:
• An inflatable bag (airbag) with a
gas generator concealed behind
the outboard bolster of the driver
and front passenger seatbacks.
• A special seat cover designed to
allow airbag deployment.
• The same warning light, electronic control and diagnostic unit as used
for the front airbags.
• Crash sensors located on the front doors.
• One crash sensor located on each side of the c-pillar (Crew cab and
SuperCab only).
Side airbags, in combination with safety belts, can help reduce the risk of
severe injuries in the event of a significant side impact collision.
The side airbags are fitted on the outboard side of the seatbacks of the
front seats. In certain lateral collisions, the airbag on the side affected by
the collision will be inflated. The airbag was designed to inflate between
the door panel and occupant to further enhance the protection provided
occupants in side impact collisions.
The airbag SRS is designed to activate when the vehicle sustains lateral
deceleration sufficient to cause the sensors to close an electrical circuit
that initiates airbag inflation. Seating and Safety Restraints

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. Side airbags are designed
to inflate in side-impact collisions, not roll-over, rear-impact, frontal or
near-frontal collisions, unless the collision causes sufficient lateral
deceleration.
WARNING: Several airbag system components get hot after
inflation. Do not touch them after inflation.
WARNING: If the side
airbag has deployed, the
airbag will not function again.
The side airbag system
(including the seat) must be
inspected and serviced by an
authorized dealer. If the airbag
is not replaced, the unrepaired
area will increase the risk of injury
in a collision.
Safety Canopy  System (if equipped)
WARNING: 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.
WARNING: Do not lean your head on the door. The Safety
Canopy  could injure you as it deploys from the headliner.Seating and Safety Restraints
