2006 FORD FREESTAR sensor

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. Front
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.

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 airbag modules (which include the inflators and
airbags).
•side airbags (if equipped). Refer toSide airbag systemlater in this
chapter.
•one or more impact and safing sensors.
•a readiness light and tone.
•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.
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
air bag 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 air bag 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 air bag 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,

Do not lean your head on the door. The side airbag could injure
you as it deploys from the side of the seatback.
Do not attempt to service, repair, or modify the airbag SRS, its
fuses or the seat cover on a seat containing an airbag. See your
authorized dealer.
All occupants of the vehicle should always wear their safety belts
even when an airbag SRS is provided.
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 nylon 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 readiness airbag light,
electronic control and diagnostic
unit as used for the front airbags.
•Two crash sensors located under
the outboard side of the front
seats, attached to the floor.
Side airbags, in combination with
seat 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, even if the respective seat is not occupied.

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.
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.
Several air bag system components get hot after inflation. Do not
touch them after inflation.
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 Canopysystem (if equipped)
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.

•An inflatable nylon curtain with a gas generator concealed behind the
headliner and above the doors (one on each side of vehicle).
•A headliner designed to flex open above the side doors to allow Safety
Canopy
deployment.
•The same readiness airbag light, electronic control and diagnostic unit
as used for the front airbags.
•Two crash sensors mounted under the front seats (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, along the entire side of the vehicle. In certain lateral collisions
or rollover events, the Safety Canopy
system will be activated,
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.
Several Safety Canopy
system components get hot after
inflation. Do not touch them after inflation.

TIRE REPLACEMENT REQUIREMENTS
Your vehicle is equipped with tires designed to provide a safe ride and
handling capability.
Only use replacement tires and wheels that are the same size
and type (such as P-metric versus LT-metric or all-season versus
all-terrain) as those originally provided by Ford. Use of any tire or
wheel not recommended by Ford can affect the safety and
performance of your vehicle, which could result in an increased risk of
loss of vehicle control, vehicle rollover, personal injury and death.
Additionally the use of non-recommended tires and wheels could cause
steering, suspension, axle or transfer case/power transfer unit failure. If
you have questions regarding tire replacement, see an authorized
dealer.
Important:Remember to replace the wheel valve stems when the road
tires are replaced on your vehicle.
It is recommended that the two front tires or two rear tires generally be
replaced as a pair.
The tire pressure monitoring sensors mounted in the wheels (originally
installed on your vehicle) are not designed to be used in after-market
wheels.
The installation of replacement tires with steel cord body plies in the tire
sidewall may cause malfunction of the Tire Pressure Monitoring System
(TPMS), and is not recommended (cord material information is molded
on the tire sidewall). Additionally, if your vehicle was originally equipped
with run-flat tires, replacing them with tires that are not identical to
those originally fitted may cause malfunction of the TPMS, and is not
recommended. Run-flat tires should not be used to replace regular tires.
Always check your TPMS indicator immediately after replacing one or
more tires on your vehicle. If the TPMS indicator is flashing, your TPMS
is malfunctioning. Your replacement tire might be incompatible with your
TPMS, or some component of the TPMS may be damaged.
INFORMATION CONTAINED ON THE TIRE SIDEWALL
Federal law requires tire manufacturers to place standardized
information on the sidewall of all tires. This information identifies and
describes the fundamental characteristics of the tire and also provides a
U.S. DOT Tire Identification Number for safety standard certification and
in case of a recall.

Changing tires with TPMS
Each road tire is equipped with
a tire pressure sensor fastened
to the inside rim of the wheel.
The pressure sensor is covered
by the tire and is not visible
unless the tire is removed. The
pressure sensor is located
opposite (180 degrees) from the
valve stem. Care must be taken
when changing the tire to avoid
damaging the sensor.It is
recommended that you always have
your tires serviced by an authorized
dealer.
The tire pressure should be checked
periodically (at least monthly) using
an accurate tire gauge, refer to
Inspecting and inflating your
tiresin this chapter.
Understanding your Tire Pressure Monitoring System (TPMS)
The Tire Pressure Monitoring System measures pressure in your four
road tires and sends the tire pressure readings to your vehicle every
minute while you are driving and once every 6 hours when your vehicle
is parked. The Low Tire Warning Lamp will turn ON if the tire pressure
is 25% below the pressure listed on the Safety Compliance Certification
Label (approximately 6 to 9 psi below the manufacturer’s recommend
tire pressure). If the tire pressure increases 2 psi above the “Light ON”
threshold, then the TPMS light will turn OFF. Once the light is
illuminated, your tires are under inflated and need to be inflated to the
manufacturer’s recommended tire pressure. Even if the light turns ON
and a short time later turns OFF, your tire pressure still needs to be
checked.
In short, once the light has turned ON, at least one tire may be under
inflated.
When your temporary spare tire is installed (if equipped)
When one of your road tires needs to be replaced with the temporary
spare (T-type spare/Mini spare or Dissimilar spare), the TPMS system
will continue to identify an issue to remind you that the damaged road

When inflating your tires
When putting air into your tires (such as at a gas station or in your
garage), the Tire Pressure Monitoring System may not respond
immediately to the air added to your tires. Here are the details:
•The tire pressure sensors mounted in your wheels updates your
vehicle with tire pressure information only once every minute,
therefore it may take up to two minutes of driving over 20 mph
(32 km/h) for the light to turn OFF after you have filled your tires to
the recommended tire pressure.
•If your vehicle has been parked for over 30 minutes, the sensors go
into a low power mode to conserve battery life and therefore only
transmit about once every 6 hours. If you inflate your tires under
these conditions, it may take up to two minutes of driving over
20 mph (32 km/h) for the light to turn OFF after you have filled your
tires to the recommended tire pressure.
For these reasons, the low tire pressure warning light is NOT a
substitute for using an accurate tire gauge when checking and filling
your tires.
