safety belt pretensioner activation depending upon safety belt usage.
Refer toSafety beltsection in this chapter.
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 and rollovers when the
vehicle is equipped with the Safety Canopysystem. 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 the
Warning lights and chimessection in theInstrument Clusterchapter.
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, driver seat
position sensor, and front passenger sensing system. 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.

Position the safety belt height adjusters so that the belt rests
across the middle of your shoulder. Failure to adjust the safety
belt properly could reduce the effectiveness of the seat belt and
increase the risk of injury in a collision.
Safety belt pretensioner
Your vehicle is equipped with safety belt pretensioners at the driver and
front outboard passenger seating positions.
The safety belt pretensioner is a device which removes excess webbing
from the safety belt system. The safety belt pretensioner uses the same
crash sensor system as the front airbag supplemental restraint system
(SRS). When the safety belt pretensioner deploys, webbing from the lap
and shoulder belt is tightened. Refer to theSafety belt maintenance
section in this chapter.
The driver and front passenger safety belt system (including
retractors, buckles and height adjusters) must be replaced if the
vehicle is involved in a collision that results in deployment of front
airbags, seat-mounted side airbags and side air curtains (if equipped),
and safety belt pretensioners.
Safety belt extension assembly
If the safety belt is too short when fully extended, there isa8inch(20cm)
safety belt extension assembly that can be added (part number 611C22).
This assembly can be obtained from an authorized dealer.
Use only extensions manufactured by the same supplier as the safety
belt. Manufacturer identification is located at the end of the webbing on
the label. Also, use the safety belt extension only if the safety belt is too
short for you when fully extended.
Do not use extensions to change the fit of the shoulder belt
across the torso.
Safety belt maintenance
Inspect the safety belt systems periodically to make sure they work
properly and are not damaged. Inspect the safety belts to make sure
there are no nicks, tears or cuts. Replace if necessary. All safety belt
assemblies, including retractors, buckles, front safety belt buckle

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”.
Do not sit on top of a buckled safety belt or insert a latchplate
into the buckle to avoid the BeltMinderchime. To do so may
adversely affect the performance of the vehicle’s air bag system.
One time disable
If at any time the driver/front passenger quickly buckles then unbuckles
the safety belt for that seating position, the BeltMinderis disabled for
the current ignition cycle. The BeltMinderfeature will enable during the
same ignition cycle if the occupant buckles and remains buckled for
approximately 30 seconds. Confirmation is not given for the one time
disable.
Deactivating/activating the BeltMinderfeature
The driver and front passenger BeltMinderare
deactivated/activated independently. When deactivating/activating
one seating position, do not buckle the other position as this will
terminate the process.

•This will enable the BeltMinderfeature for that seating position if it
is currently disabled. As confirmation, the safety belt warning light will
flash 4 times per second for 3 seconds, followed by 3 seconds with the
light off, then followed by the safety belt warning light flashing 4 times
per second for 3 seconds again.
AIRBAG SUPPLEMENTAL RESTRAINT SYSTEM (SRS)
The instrument panel grab handle should never be used for
storage. The path of an inflating airbag must be kept clear at all
times.
The airbag supplemental restraint system (SRS) is designed to work in
conjunction with the safety belts to help protect the driver and front
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.

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.
Do not place any object between an occupant and an airbag or
near any other airbag covering. The airbag may not inflate
properly and might force an object into that person causing severe
injury or death. The IP Grab Handle should never be used for storage.
The path of an inflating airbag must be kept clear at all times.
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.
Always transport children 12 years old and under in the back
seat and always properly use appropriate child restraints.
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.
Never place your arm over the air bag module as a deploying air
bag 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.
2007 Freestyle(219)
Owners Guide (post-2002-fmt)
USA(fus)
Seating and Safety Restraints
141
•Recline the seat slightly one or two degrees from the upright position.
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.
Do not attempt to service, repair, or modify the airbag
supplemental restraint systems or its fuses. See your authorized
dealer.
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.
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.

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 and curtain (if equipped). Refer toSide airbag system
later in this chapter.
•one or more impact and safing sensors.
•Safety belt pretensioner
•a readiness light and tone.
•diagnostic module.
•and the electrical wiring which connects the components.
•Front passenger sensing system. Refer toFront passenger sensing
systemlater in this chapter.
•“Passenger airbag off” or “pass airbag off” indicator lamp. Refer to
Front passenger sensing systemlater in this chapter.
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
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).
