SAFETY RESTRAINTS
Personal Safety System
The Personal Safety System provides an improved overall level of frontal
crash protection to front seat occupants and is designed to help further
reduce the risk of air bag-related injuries. The system is able to analyze
different occupant conditions and crash severity before activating the
appropriate safety devices to help better protect a range of occupants in
a variety of frontal crash situations.
Your vehicle’s Personal Safety System consists of:
•Driver and passenger dual-stage air bag supplemental restraints.
•Front safety belts with pretensioners, load limiter (first row only), and
safety belt usage sensors.
•Passenger occupant classification sensor (OCS)
•Front crash severity sensor.
•Restraints Control Module (RCM) with impact and safing sensors.
•Restraint system warning light and back-up tone.
•The electrical wiring for the air bags, crash sensor(s), safety belt
pretensioners, front safety belt usage sensors, driver seat position
sensor, passenger occupant classification sensor, and indicator lights.
How does the Personal Safety System work?
The Personal Safety System can adapt the deployment strategy of your
vehicle’s safety devices according to crash severity and occupant
conditions. A collection of crash and occupant sensors provides
information to the Restraints control module (RCM). During a crash, the
RCM activates the safety belt pretensioners and/or either one or both
stages of the dual-stage air bag supplemental restraints based on crash
severity and occupant conditions.
The fact that the pretensioners or air bags did not activate for both front
seat occupants in a collision does not mean that something is wrong with
the system. Rather, it means the Personal Safety System determined the
accident conditions (crash severity, belt usage, etc.) were not
appropriate to activate these safety devices. Front air bags and
pretensioners are designed to activate only in frontal and near-frontal
collisions, not rollovers, side-impacts, or rear-impacts unless the collision
causes sufficient longitudinal deceleration.

Driver and passenger dual-stage air bag supplemental restraints
The dual-stage air bags offer the capability to tailor the level of air bag
inflation energy. A lower, less forceful energy level is provided for more
common, moderate-severity impacts. A higher energy level is used for
the most severe impacts. Refer toAir bag supplemental restraints
section in this chapter.
Front crash severity sensor
The front crash severity sensor enhances the ability to detect the
severity of an impact. Positioned up front, it provides valuable
information early in the crash event on the severity of the impact. This
allows your Personal Safety System to distinguish between different
levels of crash severity and modify the deployment strategy of the
dual-stage air bags and safety belt pretensioners.
Driver’s seat position sensor
The driver’s seat position sensor allows your Personal Safety System to
tailor the deployment level of the driver dual-stage air bag based on seat
position. The system is designed to help protect smaller drivers sitting
close to the driver air bag by providing a lower air bag output level.
Occupant Classification Sensor (OCS)
For air bags to do their job they must inflate with great force, and this
force can pose a potentially deadly risk to occupants that are very close
to the air bag when it begins to inflate. For some occupants, like infants
in rear-facing child seats, this occurs because they are initially sitting
very close to the air bag. For other occupants, this occurs when the
occupant is not properly restrained by seat belts or child safety seats and
they move forward during pre-crash braking. The most effective way to
reduce the risk of unnecessary injuries is to make sure all occupants are
properly restrained. Accident statistics suggest that children are much
safer when properly restrained in the rear seating positions than in the
front.
WARNING: Air bags can kill or injure a child in a child seat.
NEVER place a rear-facing child seat in front of an active air
bag. If you must use a forward-facing child seat in the front
seat, move the seat all the way back.
WARNING: Always transport children 12 years old and under
in the back seat and always properly use appropriate child
restraints.

The front passenger sensing system can automatically turn off the
passenger front air bag. The system is designed to help protect small
(child size) occupants from air bag deployments when they are
improperly seated or restrained in the front passenger seat contrary to
proper child-seating or restraint usage recommendations. Even with this
technology, parents areSTRONGLYencouraged to always properly
restrain children in the rear seat. The sensor also turns off the passenger
front air bag and seat-mounted side air bag (if equipped) when the
passenger seat is empty to prevent unnecessary replacement of air
bag(s) after a collision.
When the front passenger seat is occupied and the sensing system has
turned off the passenger’s frontal air bag, the“pass air bag off”indicator
will light and stay lit to remind you that the front passenger frontal air
bag is off. SeeFront passenger sensing systemin the airbags section of
this chapter.
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 System to tailor the air bag deployment and
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 a frontal or near-frontal collision. This maximizes the effectiveness
of the safety belts and helps properly position the occupant relative to
the air bag to improve protection. The safety belt pretensioners can be
either activated alone or, if the collision is of sufficient severity, together
with the air bags.
Front safety belt load limiter
The front outboard safety belt load limiter allows 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 toLoad limiter featuresection 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 theWarning lightsection in theInstrument clusterchapter. 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 air bag supplemental restraints, crash sensor(s),
safety belt pretensioners, front safety belt buckle sensors, driver seat
position sensor, and passenger occupant classification sensor. In addition,
the RCM also monitors the restraints warning light in the instrument
cluster. A malfunction 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 System serviced by your authorized Mazda dealership
immediately. Unless serviced, the system may not function properly in
the event of a collision.
Safety restraints precautions
WARNING: Always drive and ride with your seatback upright
and the lap belt snug and low across the hips.
WARNING: To reduce the risk of injury, make sure children sit
where they can be properly restrained.
WARNING: Never let a passenger hold a child on his or her lap
while the vehicle is moving. The passenger cannot protect the
child from injury in a collision.
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: After any vehicle collision, the safety belt systems
at all seating positions (except the driver position, which
doesn’t have this feature) must be checked by a qualified
technician to verify that the automatic locking retractor feature
for child seats is still functioning properly. In addition, all seat
belts should be checked for proper function.
WARNING: BELT AND RETRACTOR ASSEMBLY MUST BE
REPLACED if the seat belt assembly“automatic locking
retractor”feature or any other seat belt function is not
operating properly when checked according to the procedures in
Workshop Manual. Failure to replace the Belt and Retractor
assembly could increase the risk of injury in collisions.
Safety belt height adjustment
Your vehicle has safety belt height
adjustments at the front outboard
seating positions. Adjust the height
of the shoulder belt so the belt rests
across the middle of your shoulder.
To adjust the shoulder belt height,
squeeze and hold the buttons on the
side and slide the height adjuster up
or down. Release the buttons and
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
safety 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
right front passenger seating positions.
The safety belt pretensioner removes some slack from the safety belt
system at the start of a crash. The safety belt pretensioner uses the
same crash sensor system as the front airbags and side-curtain air bags
(if equipped). When the safety belt pretensioner deploys, the lap and
shoulder belt are tightened.

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 warning light and indicator chime
The safety belt warning light illuminates in the instrument cluster and a
chime sounds to remind the occupants to fasten their safety belts.

BeltMinder
The BeltMinder feature is a supplemental warning to the safety belt
warning function. This feature provides additional reminders by
intermittently sounding a chime and illuminating the safety belt warning
lamp in the instrument cluster when the driver’s and front passenger’s
safety belt is unbuckled.
The BeltMinder feature uses information from the passenger occupant
classification sensor to determine if a front seat passenger is present and
therefore potentially in need of a warning. To avoid activating the
BeltMinder feature for objects placed in the front passenger seat,
warnings will only be given to large front seat occupants as determined
by the passenger occupant classification sensor.

WARNING: Do not put anything on or over the air bag module
including hands or feet. 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.
WARNING: Do not attempt to service, repair, or modify the Air
Bag Supplemental Restraint Systems 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 affect the performance of the air bag
sensors increasing the risk of injury. Do not modify the front
end of the vehicle.
WARNING: Additional equipment may affect the performance
of the air bag sensors increasing the risk of injury. Consult your
authorized Mazda dealership before installation of additional
equipment.
Children and air bags
For additional important safety
information, read all information on
safety restraints in this guide.
WARNING: 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.

WARNING: Air bags can kill or injure a child in a child seat
NEVER place a rear-facing child seat in front of an active air
bag. If you must use a forward-facing child seat in the front
seat, move the seat all the way back. Secure the seat and the
child in it properly.
How does the air bag supplemental restraint system work?
The air bag SRS is designed to
activate when the vehicle sustains
longitudinal deceleration sufficient
to cause the sensors to close an
electrical circuit that initiates air
bag inflation.
The fact that the air bags 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. Air bags 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 air bags inflate and deflate
rapidly upon activation. After air bag
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
air bag. 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 air bag may also cause abrasions, swelling or temporary

hearing loss. Because air bags 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 air bag deployment. Thus, it is extremely important that occupants be
properly restrained as far away from the air bag module as possible while
maintaining vehicle control.
WARNING: Several air bag system components get hot after
inflation. Do not touch them after inflation or you may be
burned.
WARNING: If the air bag and safety belt pretensioners have
deployed, the air bag and safety belt pretensioners will not
function again and must be replaced immediately. If the air bag
and safety belt pretensioners are not replaced, the unrepaired
area will increase the risk of injury in a collision.
The SRS consists of:
•driver and passenger air bag modules (which include the inflators and
air bags),
•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 air bag electrical system wiring (including the impact
sensors), the system wiring, the air bag system readiness light, the air
bag back up power and the air bag ignitors.
Front passenger sensing system
The front passenger sensing system will turn off the front passenger’s
frontal air bag under certain conditions. The front passenger
seat-mounted side air bag (if equipped) will be deactivated if the sensor
detects an empty seat; otherwise, the seat-mounted side air bag will be
enabled. 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 not.

How does the side air bag system work?
The design and development of the
side air bag system included
recommended testing procedures
that were developed by a group of
automotive safety experts known as
the Side Air Bag Technical Working
Group. These recommended testing
procedures help reduce the risk of
injuries related to the deployment of
side air bags.
The side air bag system consists of
the following:
•An inflatable nylon bag (air bag)
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 warning light, electronic control and diagnostic unit as used
for the front air bags.
•Two crash sensors located on the lower portion of the b-pillar (one on
each side of the vehicle).
Side air bags, in combination with seat belts, can help reduce the risk of
severe injuries in the event of a significant side impact collision.
The side air bags are fitted on the outboard side of the seatbacks of the
front seats. In certain lateral collisions, the air bag on the side affected
by the collision will be inflated. If the front passenger sensing system
detects an empty seat, the front passenger seat-mounted side air bag will
be deactivated. The air bag was designed to inflate between the door
panel and occupant to further enhance the protection provided
occupants in side impact collisions.
The air bag SRS is designed to activate when the vehicle sustains lateral
deceleration sufficient to cause the sensors to close an electrical circuit
that initiates air bag inflation.
The fact that the air bags 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 air bags are designed
