2010 FORD E450 Owners Manual

How does the airbag supplemental restraint system work?
The airbag SRS is designed to
activate when the vehicle sustains a
longitudinal deceleration sufficient
to cause the airbag 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 sufficient
enough to cause activation. 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 or sodium compounds which
may irritate the skin and eyes, but
none of the residue is toxic.
While the SRS 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. 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:
•driver and passenger airbag modules (which include the inflators and
airbags)
•one or more impact and safing sensors

•safety belt pretensioners
•a readiness light and tone
•a diagnostic module
•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
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.
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 theWarning lights and
chimessection in theInstrument 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 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, contact your
authorized dealer as soon as possible. Unless serviced, the system may
not function properly in the event of a collision.
SOS Post-Crash Alert System™
The system automatically flashes the turn signal lamps and sounds the
horn three times at four second intervals in the event of a serious impact
that deploys an airbag (front, side, side curtain or Safety Canopy)or
the safety belt pretensioners.

The system can be turned off when any one of the following actions are
taken by the driver or any other person:
•pressing the hazard control button,
•or pressing the panic button on the remote entry transmitter.
The feature will continue to operate until the vehicle runs out of power.
Disposal of airbags and airbag equipped vehicles (including
pretensioners)
Contact your authorized dealer as soon as possible. Airbags MUST BE
disposed of by qualified personnel.
Passenger airbag ON/OFF switch (if equipped)
Note: The passenger airbag ON/OFF
switch (if equipped) may be on
vehicles with no rear seats and a
gross vehicle weight rating (GVWR)
greater than 8500 lb (3856 kg). See
Vehicle loading – with and
without a trailerin theTires,
Wheels and loadingchapter.
WARNING:An airbag
ON/OFF switch (if
equipped) may have been installed
in this vehicle. Before driving,
alwayslook at the face of the
switch to be sure the switch is in
the proper position in accordance
with these instructions and
warnings. Failure to put the
switch in a proper position can
increase the risk of serious injury
or death in a collision.

Turning the passenger airbag off
1. Insert the ignition key, turn the
switch to OFF position and hold in
OFF position while removing the
key.
2. When the ignition is turned to the
ON position the OFF light
illuminates briefly, momentarily
shuts off and then turns back on.
This indicates that the passenger
airbag is deactivated.
WARNING:If the light fails to illuminate when the passenger air
bag switch is in the OFF position and the ignition switch is in
ON, contact your authorized dealer as soon as possible.
WARNING:In order to avoid inadvertent activation of the
switch, always remove the ignition key from the passenger air
bag ON/OFF switch.
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.
Turning the passenger airbag back on
The passenger airbag remains OFF until you turn it back ON.
1. Insert the ignition key and turn
the switch to ON.
2. The OFF light will briefly
illuminate when the ignition is
turned to On. This indicates that the
passenger airbag is operational.

WARNING:If the OFF light is illuminated when the passenger
airbag switch is in the ON position and the ignition switch is in
ON, have the passenger airbag switch serviced at an authorized dealer
immediately.
The passenger side airbag should always be ON (the airbag OFF light
shouldnotbe illuminated) unless the passenger is a person who meets
the requirements stated either in Category 1, 2 or 3 of the
NHTSA/Transport Canada deactivation criteria which follows.
WARNING:The safety belts for the driver and right front
passenger seating positions have been specifically designed to
function together with the airbags in certain types of crashes. When
you turn OFF your airbag, you not only lose the protection of the
airbag, you also may reduce the effectiveness of your safety belt
system, which was designed to work with the airbag. If you are not a
person who meets the requirements stated in the NHTSA/Transport
Canada deactivation criteria turning OFF the airbag can increase the
risk of serious injury or death in a collision.
WARNING:If your vehicle has rear seats, always transport
children who are 12 and younger in a rear seating position.
Always use safety belts and child restraints properly. DO NOT place a
child in a rear facing infant seat in the front seat unless your vehicle is
equipped with an airbag ON/OFF switch and the passenger airbag is
turned OFF. 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 vast majority of drivers and passengers are much safer with an airbag
than without. To do their job and reduce the risk of life threatening
injuries, airbags must open with great force, and this force can pose a
potentially deadly risk in some situations, particularly when a front seat
occupant is not properly buckled up. The most effective way to reduce the
risk of unnecessary airbag injuries without reducing the overall safety of
the vehicle is to make sure all occupants are properly restrained in the
vehicle, especially in the front seat. This provides the protection of safety
belts and permits the airbags to provide the additional protection they
were designed to provide. If you choose to deactivate your airbag, you are
losing the very significant risk reducing benefits of the airbag and you are
also reducing the effectiveness of the safety belts, because safety belts in
modern vehicles are designed to work as a safety system with the airbags.

NHTSA deactivation criteria (excluding Canada)
1.Infant.An infant (less than 1 year old) must ride in the front seat
because:
•the vehicle has no rear seat;
•the vehicle has a rear seat too small to accommodate a rear-facing
infant seat; or
•the infant has a medical condition which, according to the infant’s
physician, makes it necessary for the infant to ride in the front so that
the driver can constantly monitor the child’s condition.
2.Child age 1 to 12.A child age 1 to 12 must ride in the front seat
because:
•the vehicle has no rear seat;
•although children ages 1 to 12 ride in the rear seat(s) whenever
possible, children ages 1 to 12 sometimes must ride in the front
because no space is available in the rear seat(s) of the vehicle; or
•the child has a medical condition which, according to the child’s
physician, makes it necessary for the child to ride in the front seat so
that the driver can constantly monitor the child’s condition.
3.Medical condition.A passenger has a medical condition which,
according to his or her physician:
•causes the passenger airbag to pose a special risk for the passenger;
and
•makes the potential harm from the passenger airbag in a crash greater
than the potential harm from turning OFF the airbag and allowing the
passenger, even if belted, to hit the dashboard or windshield in a
crash.

WARNING:This vehicle has special energy management safety
belts for the driver and right front passenger. These particular
belts are specifically designed to work with airbags to help reduce the
risk of injury in a collision. The energy management safety belt is
designed to give or release additional belt webbing in some accidents
to reduce concentration of force on an occupant’s chest and reduce the
risk of certain bone fractures and injuries to underlying organs. In a
crash, if the airbag is turned OFF, this energy management safety belt
might permit the person wearing the belt to move forward enough to
incur a serious or fatal injury. The more severe the crash, and the
heavier the occupant, the greater the risk is. Be sure the airbag is
turned ON for any person who does not qualify under the NHTSA
deactivation criteria.
Transport Canada deactivation criteria (Canada Only)
1.Infant:An infant (less than 1 year old) must ride in the front seat
because:
•my vehicle has no rear seat;
•the rear seat in my vehicle cannot accommodate a rear-facing infant
seat; or
•the infant has a medical condition which, according to the infant’s
physician, makes it necessary for the infant to ride in the front seat so
that the driver can monitor the infant’s condition.
2.Child age 12 or under:A child age 12 or under must ride in the
front seat because:
•my vehicle has no rear seat;
•although children age 12 and under ride in the rear seat whenever
possible, children age 12 and under have no option but to sometimes
ride in the front seat because rear seat space is insufficient; or
•the child has a medical condition that, according to the child’s
physician, makes it necessary for the child to ride in the front seat so
that the driver can monitor the child’s condition.
3.Medical condition:A passenger has a medical condition that,
according to his or her physician:
•poses a special risk for the passenger if the airbag deploys; and
•makes the potential harm from the passenger airbag deployment
greater than the potential harm from turning OFF the airbag and
experiencing a crash without the protection offered by the airbag
