2007 MAZDA MODEL B3000 TRUCK airbag

Front safety belt usage sensors
The front safety belt usage sensors detect whether or not the driver and
front outboard passenger safety belts are fastened. This information
allows your Personal Safety Systemto tailor the airbag deployment and
safety belt pretensioner activation depending upon safety belt usage.
Refer to Safety belt usage sensors later in this chapter.
Front outboard 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 Canopy system. 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 outboard safety belt energy management retractors
The front 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 to Energy management retractors section in
this chapter.
Determining if the Personal Safety System is operational
The Personal Safety System uses 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 chimes section in theInstrument Cluster
chapter. Routine maintenance of the Personal Safety System is 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, front
passenger sensing system, and the driver seat position sensor. 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.

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.
WARNING: 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 and safety belt pretensioners.
Front safety belt height adjustment
Your vehicle has safety belt height adjustments for the driver and front
passenger. Adjust the height of the shoulder belt so the belt rests across
the middle of your shoulder.
• Regular Cab and four–door Cab
Plus 4
To lower the shoulder belt height, push the button and slide the height
adjuster down. To raise the height of the shoulder belt, slide the height
adjuster up. Pull down on the height adjuster to make sure it is locked in
place. WARNING: 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 extension assembly
If the safety belt assembly is too short for you, even when fully
extended, 20 cm (8 inches) can be added to the safety belt assembly by
adding a safety belt extension assembly. Safety belt extension assemblies
can be obtained from your authorized Mazda dealership.
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.
NOTE: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.
NOTE: If unsure about the proper procedures, bring your vehicle to an
authorized Mazda dealership for inspection. Inspect the safety belts to
make sure there are no nicks, tears or cuts, replacing if necessary. Check
the automatic locking retractor on the passenger outboard seating position.
All safety belt assemblies, including retractors, buckles, front safety belt
buckle assemblies, buckle support assemblies (slide bar-if equipped),
shoulder belt height adjusters (if equipped), shoulder belt guide on
seatback (if equipped), child safety seat tether bracket assemblies (if
equipped), and attaching hardware, should be inspected after a collision.
Mazda recommends that all safety belt assemblies used in vehicles involved
in a collision be replaced. However, if the collision was minor and an
authorized Mazda technician finds that the belts do not show damage and
continue to operate properly, they do not need to be replaced. Safety belt
assemblies not in use during a collision should also be inspected and
replaced if either damage or improper operation is noted.
The energy absorbing functions may have been activated in a collision so
the restraints should be examined; if the front airbags have deployed, the
pretensioners have also deployed and must be replaced — regardless of
whether there was an occupant in the passenger seat or not.
WARNING: Failure to inspect and if necessary replace the
safety belt assembly under the above conditions could result in
severe personal injuries in the event of a collision.
Refer to Interior in theCleaning chapter.

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. Peoplewho are
ejected are 40 times more likely
to DIE. Safety belts help prevent
ejection, WE CAN’T PICK OUR
CRASH.
WARNING: Always wear the safety belt. Do not be tempted to
sit on top of the belt to fool police or to defeat the warning
system. The safety belt and safety belt warning system are
there to protect your life.
One time disable
If at any time the driver/front passenger quickly buckles then unbuckles
the safety belt for that seating position, the BeltMinder
is disabled for
the current ignition cycle. The BeltMinder
feature 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 BeltMinder feature
The driver and front passenger BeltMinder
are
deactivated/activated independently. When deactivating/activating
one seating position, do not buckle the other position as this will
terminate the process.
Read Steps1-4t horoughly before proceeding with the
deactivation/activation programming procedure.
Note: The driver and front passenger BeltMinder
features must be
disabled/enabled separately. Both cannot be disable/enabled during the
same key cycle.

AIRBAG SUPPLEMENTAL RESTRAINT SYSTEM (SRS)
The airbag supplemental restraint system 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.
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 System section in this chapter.
Important supplemental restraint system (SRS) precautions
The supplemental restraint system is designed to work with the safety
belt to help protect the driver and right front passenger from certain
upper body injuries.

WARNING: Airbags DO NOT
inflate slowly or gently and the
risk of injury from a deploying
airbag is greatest close to the
trim covering the airbag
module. Always wear your
safety belt.
WARNING: Airbags have been known to kill or injure a child in
front facing child restraints. When placing a child safety seat in
a front seating position including the center (if equipped), you
should make sure that the passenger airbag is off. If the child
safety seat is in the outboard seating position, slide the seat all
the way back.
WARNING: Do not install a
child seat in a center facing
jump seat.
WARNING: Rear facing child
seats should NEVER be placed
in front of an active airbag.
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: National Highway Traffic Safety Administration
(NHTSA) recommends a minimum distance of at least 25 cm (10
inches) between an occupant’s chest and the driver air bag
module.
WARNING: Never place your arm or feet over the airbag
module as a deploying airbag can result in serious arm fractures
or other injuries.
Steps you can take 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
including hands or feet. 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 System or its fuses. See your
authorized Mazda dealership.
WARNING: Modifications to the front end of the vehicle,
including frame, bumper, front end body structure, tow hooks
and snow plows may effect the performance of the airbag
sensors increasing the risk of injury. Do not modify the front
end of the vehicle.
WARNING: Additional equipment may effect the performance
of the airbag sensors increasing the risk of injury. Consult your
authorized Mazda dealership before installation of additional
equipment.
WARNING: The front passenger airbag is not designed to offer
protection to an occupant in the center front seating position.

Children and airbags
For additional important safety information, read all information on
safety restraints in this guide.WARNING: Do not install a
child seat in a center facing
jump seat.
WARNING: Airbags can kill or
injure a child in a child seat.
NEVER place 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.
WARNING: Booster seats must be installed only in seating
positions equipped with a combination lap/shoulder belt.
WARNING: To reduce the risk of injury, make sure children sit
where they can be properly restrained.
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.
