AIRBAG SUPPLEMENTAL RESTRAINT SYSTEM (SRS)
Important supplemental restraint system (SRS) precautions
The supplemental restraint system
is designed to work with the seat
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.
WARNING: All occupants of the vehicle, including the driver,
should always properly wear their seat belts, even when an air
bag supplemental restraint system (SRS) is provided.
WARNING: Always transport children 12 years old and under
in the back seat and always properly use appropriate child
restraint systems.
WARNING: 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.

WARNING: The driver should always hold onto only the rim of
the steering wheel. Never place your arm over the airbag
module or anywhere inside the rim 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 notches) 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 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 airbag
sensors increasing the risk of injury. Do not modify the front
end of the vehicle.
WARNING: Additional equipment may affect the performance
of the airbag sensors increasing the risk of injury. Consult your
authorized Mazda dealership before installation of additional
equipment.

Children and airbags
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 rather than
in the front seating position.
Failure to follow these
instructions may increase the
risk of injury in a collision.
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. Secure the seat and the
child in it properly.
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. 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. WARNING:
Several airbag system components get hot after
inflation. Do not touch them after inflation or you may be burned.
WARNING: If the airbag and seat belt pretensioners have
deployed, the airbag or seat belt pretensioners will not function
again and must be replaced immediately. If the airbag or seat
belt pretensioners are 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),
• seat-mounted side airbags (if equipped). Refer to Seat-mounted side
airbag system later 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.

•Side curtain airbag system. Refer to Side curtain airbag systemlater
in this chapter.
• Front passenger sensing system. Refer to Front passenger sensing
system. later in this chapter.
• “Passenger airbag off” or “pass airbag off” indicator lamp. Refer to
Front passenger sensing system. later in this chapter.
• Seat belt pretensioners
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 seat 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).
The front passenger sensing system will disable (will not inflate) the
front passenger’s frontal airbag 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,
• the system determines that a small child is present in a forward-facing
child restraint that is installed according to the manufacturer’s
instructions,
• the system determines that a small child is present in a booster seat,
• a front passenger takes his/her weight off of the seat for a period of
time,
For side airbag equipped vehicles, the front passenger sensing system
will turn off the passenger seat side airbag if:
• the seat is empty and seat belt is unbuckled.

The front passenger sensing system
uses a passenger airbag off or
pass airbag off indicator which will
illuminate and stay lit to remind you
that the front passenger frontal airbag is disabled. The indicator lamp is
located in the center stack of the instrument panel just above the air
vents.
Note : The indicator lamp will illuminate for a short period of time when
the ignition is turned to the ON position to confirm it is functional.
When the front passenger seat is not occupied (empty seat) or in the
event that the front passenger frontal airbag is enabled (may inflate), the
indicator lamp will be unlit.
The front passenger sensing system is designed to disable (will not
inflate) the front passenger’s frontal airbag when a rear facing infant
seat, a forward-facing child restraint, or a booster seat is detected.
• When the front passenger sensing system disables (will not inflate)
the front passenger frontal airbag, the indicator lamp will illuminate
and stay lit to remind you that the front passenger frontal airbag is
disabled.
• If the child restraint has been installed and the indicator lamp is not
lit, then turn the vehicle off, remove the child restraint from the
vehicle and reinstall the restraint following the child restraint
manufacturer’s instructions.
The front passenger sensing system is designed to enable (may inflate)
the front passenger’s frontal airbag anytime the system senses that a
person of adult size is sitting properly in the front passenger seat.
• When the front passenger sensing system enables the front passenger
frontal airbag (may inflate), the indicator will be unlit and stay unlit.
If a person of adult size is sitting in the front passenger’s seat, but the
passenger airbag off or pass airbag off indicator lamp is lit, it is
possible that the person isn’t sitting properly in the seat. If this happens:
• Turn the vehicle off and ask the person to place the seatback in the
full upright position.
• Have the person sit upright in the seat, centered on the seat cushion,
with the person’s legs comfortably extended.
• Restart the vehicle and have the person remain in this position for
about two minutes. This will allow the system to detect that person
and enable the passenger’s frontal airbag.

•If the indicator lamp remains lit even after this, the person should be
advised to ride in the rear seat, and the system should be taken
promptly to an authorized Mazda dealer for repair before that seat is
occupied again.
Occupant Pass Airbag Off
Indicator Lamp Passenger Airbag
Empty seat Unlit Disabled
Small child in child
safety seat or booster Lit Disabled
Small child with seat
belt buckled or
unbuckled Lit Disabled
Adult Unlit Enabled WARNING: Even with Advanced Restraints Systems, children
12 and under should be properly restrained in the back seat.
After all occupants have adjusted their seats and put on seat belts, it’s
very important that they continue to sit properly. A properly seated
occupant sits upright, leaning against the seat back, and centered on the
seat cushion, with their feet comfortably extended on the floor. Sitting
improperly can increase the chance of injury in a crash event. For
example, if an occupant slouches, lies down, turns sideways, sits forward,
leans forward or sideways, or puts one or both feet up, the chance of
injury during a crash is greatly increased. WARNING: Sitting improperly out of position or with the seat
back reclined too far can take off weight from the seat cushion
and affect the decision of the front passenger sensing system,
resulting in serious injury or death in a crash.
Always sit upright against your seatback, with your feet on the
floor.

The front passenger sensing system may detect small or medium objects
placed on the seat cushion. For most objects that are in the front
passenger seat, the passenger airbag will be disabled. Even though the
passenger airbag is disabled, the pass airbag offlamp may or may not
be illuminated according to the table below.
Objects Pass Airbag Off
Indicator Lamp Passenger Airbag
Small (i.e. 3 ring
binder, small purse,
bottled water) Unlit Disabled
Medium (i.e. heavy
briefcase, fully packed
luggage) Lit Disabled
Empty seat, or small
to medium object with
seat belt buckled Lit Disabled
If you think that the status of the passenger airbag off indicator lamp is
incorrect, check for the following:
• Objects lodged underneath the seat
• Objects between the seat cushion and the center console (if
equipped)
• Objects hanging off the seat back
• Objects stowed in the seatback map pocket (if equipped)
• Objects placed on the occupant’s lap
• Cargo interference with the seat
• Other passengers pushing or pulling on the seat
• Rear passenger feet and knees resting or pushing on the seat
The conditions listed above may cause the weight of a properly seated
occupant to be incorrectly interpreted by the front passenger sensing
system. The person in the front passenger seat may appear heavier or
lighter due to the conditions described in the list above.
