2008 FORD F150 airbag

outboard passenger from certain upper body injuries. The term
“supplemental restraint” means the airbags are intended as a supplement
to the safety belts. Airbags alone cannot protect as well as airbags plus
safety belts in impacts for which the airbags are designed to deploy, and
airbags do not offer any protection in crashes for which they do not
deploy.
The airbag supplemental restraint system consists of:
•driver and passenger dual stage airbag modules (which include the
inflators and airbags).
•one or more impact and safing sensors.
•the same indicator light, RCM (restraints control module) and
diagnostic unit used for the Personal safety system.
•Front passenger sensing system
•Passenger airbag off indicator light.
The airbag supplemental restraints are an integral part of the Personal
Safety System. They are designed to be deployed in cases where the
Personal Safety System has determined the occupant conditions and
crash severity are appropriate to activate these devices. Refer to the
Personal Safety Systemsection in this chapter.
Important SRS precautions
All occupants of the vehicle,
including the driver, should
always properly wear their safety
belts, even when an airbag (SRS)
is provided.
Always transport children
12 years old and under in
the back seat if your vehicle has a
back seat. Rear facing infant seats
should NEVER be placed in the
front seats. This is because the
back of the infant seat is too close
to the inflating airbag and the risk
of a fatal injury to the infant when
the airbag inflates is substantial.

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 cover.
Never place your arms or feet over the airbag module as a
deploying airbag can result in serious 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.
Do not put anything on or
over the airbag cover (1).
Placing objects on or over the
airbag cover may cause those
objects to be thrown by the airbag
into your face and torso or may
result in a failure of the airbag to
inflate properly, both of which
could result in serious injury.
Do not attempt to service, repair, or modify the airbag
supplemental restraint systems or its fuses. See your authorized
dealer.
The front passenger airbag 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 airbag system, increasing the
risk of injury. Do not modify the front end of the vehicle.

Additional equipment may affect the performance of the airbag
sensors increasing the risk of injury. Please refer to theBody
Builders Layout Bookfor 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. Accident statistics
suggest that children are safer when
properly restrained in the rear seat
than in the front seat. Failure to
follow these instructions may
increase the risk of injury in a
collision.
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.
If two adults and a child occupy aRegular Cab, properly restrain the
child in the center front unless doing so would interfere with driving the
vehicle. This arrangement provides lap and shoulder belt protection for
all occupants, and airbag protection for the adults. A child or infant
properly restrained in the center front seat should not incur risk of
serious injury from the airbags.

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.
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 cover as possible while
maintaining vehicle control.
Several airbag system components get hot after inflation. Do not
touch them after inflation.

If the airbag has deployed,the airbag will not function again
and must be replaced immediately.If the airbag is not
replaced, the unrepaired area will increase the risk of injury in a
collision.
Determining if the system is operational
The SRS uses readiness lights in the instrument cluster or a tone to
indicate the condition of the system. Refer toAirbag readinessin the
Instrument Clusterchapter. Routine maintenance of the airbag is not
required.
A difficulty with the system is indicated by one or more of the following:
•The readiness lights will either
flash or stay lit.
•The readiness lights 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 an authorized dealer immediately. Unless serviced, the system may not
function properly in the event of a collision.
Disposal of airbags and airbag equipped vehicles
(including pretensioners)
See your authorized dealer. Airbags MUST BE disposed of by qualified
personnel.
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.
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,
•a child or a small person occupies the front passenger seat.
The front passenger sensing system
uses a
passenger airbag off
or

pass airbag off
indicator which will
illuminate and stay lit to remind you
that the front passenger frontal airbag is disabled. The indicator lamp is
located in the center stack of the instrument panel just above the radio.
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.
•If the child restraint has been installed and the indicator lamp is not
lit, then turn the vehicle off, remove the child restraint from the
vehicle and reinstall the restraint following the child restraint
manufacturer’s instructions.
The front passenger sensing system is designed to enable (may inflate)
the front passenger’s frontal airbag anytime the system senses that a
person of adult size is sitting properly in the front passenger seat.

•When the front passenger sensing system enables the front passenger
frontal airbag (may inflate), the indicator will be unlit and stay unlit.
If a person of adult size is sitting in the front passenger’s seat, but the

passenger airbag off
or
pass airbag off
indicator lamp is lit, it is
possible that the person isn’t sitting properly in the seat. If this happens:
•Turn the vehicle off and ask the person to place the seatback in the
full upright position.
•Have the person sit upright in the seat, centered on the seat cushion,
with the person’s legs comfortably extended.
•Restart the vehicle and have the person remain in this position for
about two minutes. This will allow the system to detect that person
and enable the passenger’s frontal airbag.
•If the indicator lamp remains lit even after this, the person should be
advised to ride in the rear seat.

Adult Unlit Enabled
Even with Advanced Restraints Systems, children 12 and under
should be properly restrained in the back seat.
After all occupants have adjusted their seats and put on safety belts, it’s
very important that they continue to sit properly. A properly seated
occupant sits upright, leaning against the seat back, and centered 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 is greatly increased.
Sitting improperly out of position or with the seat back reclined
too far can take off weight from the seat cushion and affect the
decision of the front passenger sensing system, resulting in serious
injury or death in a crash.
Always sit upright against your seatback, with your feet on the floor.

The front passenger sensing system may detect small or medium objects
placed on the seat cushion. For most objects that are in the front
passenger seat, the passenger airbag will be disabled. Even though the
passenger airbag is disabled, the
pass airbag off
lamp may or may not
be illuminated according to the table below.

In case there is a problem with the
front passenger sensing system, the
airbag readiness lamp in the
instrument cluster will stay lit.
DO NOT attempt to repair or service the system; take your vehicle
immediately to an authorized dealer.
The front passenger airbag is not designed to offer protection to
an occupant in the center seating position.
An out of position front center occupant could affect the
decision of the front passenger sensing system.
If it is necessary to modify an advanced front airbag system to
accommodate a person with disabilities, contact the Ford Customer
Relationship Center at the phone number shown in theCustomer
Assistancesection of thisOwner’s Guide.
Any alteration/modification to the front passenger seat may
affect the performance of the front passenger sensing system.
