How the SRS Air Bags Work
Your Mazda is equipped with the following types of SRS air bags. SRS air bags are
designed to work together with the seat belts to help to reduce injuries during an accident.
The SRS air bags are designed to provide further protection for passengers in addition to the
seat belt functions. Be sure to wear seat belts properly.
▼ Seat Belt Pretensioners
The seat belt pretensioners are designed to deploy in moderate
or severe frontal, near frontal
collisions.
In addition, during a side collision, the pretensioner operates . The pretensioners operate
differently depending on what types of air bags are equipped. F or more details about seat
belt pretensioner operation, refer to the SRS Air Bag Deployment Criteria (page 2-46).
▼ Driver Air Bag
The driver's air bag is mounted in the steering wheel.
When air bag crash sensors detect a frontal impact of greater than moderate force, the
driver's air bag inflates quickly
helping to reduce injury mainly to the driver's head or chest
caused by directly hitting the steering wheel.
For more details about air bag deployment, refer to "SRS Air Ba g Deployment Criteria"
(page 2-46).
(Except Mexico)
The driver's dual-stage air bag controls air bag inflation in two energy stages. During an
impact of moderate severity, the driver's air bag deploys with lesser energy, whereas during
more severe impacts, it deploys with more energy.

NOTEIn a frontal offset collision, the equipped air bags and pretensioners may all deploy depending on the direction,
angle, and rate of impact.

Passenger Occupant Classification System
First, please read "Supplemental Restraint System (SRS) Precautions" (page 2-36) carefully.
▼Passenger Occupant Classification Sensor
Your vehicle is equipped with a passenger occupant classificati
on sensor as a part of the
supplemental restraint system. This sensor is equipped in the p assenger's seat cushion. This
sensor measures the electrostatic capacity of the passenger's s eat. The SAS unit is designed
to prevent the passenger front and side air bags and seat belt pretensioner system from
deploying if the passenger air b ag deactivation indicator light turns on.
To reduce the chance of injuries caused by deployment of the passenger air bag, the system
deactivates the passenger front and side air bags and also the seat belt pretensioner system
when the passenger air bag deactivation indicator light turns o n. Refer to the following table
for the passenger air bag deactivation indicator light illumina tion conditions.

This system shuts off the passenger front and side air bags and seat belt pretensioner system,
so make sure the passenger air bag deactivation indicator light turns on according to the
following table.

The air bag/seat belt pretension er system warning light flashes and the passenger air bag
deactivation indicator light illu minates if the sensors have a possible malfunction. If this
happens, the passenger front and side air bags and seat belt pr etensioner system will not
deploy.
Passenger air bag deactivation indicator light
This indicator light turns on to remind you that the passenger front and side air bags and seat
belt pretensioner will not deploy during a collision.
Ty p e A
If the passenger occupant classification sensor is normal, the indicator light turns on when
the ignition is switched ON. The light turns off after a few se conds. Then, the indicator light
turns on or is off under the following conditions:

the person's physique.
If the passenger air bag deactiv ation indicator light does not turn on when the ignition is
switched ON and does not turn on as indicated in the passenger air bag deactivation

Luggage or other items placed under the passe nger seat or between the passenger seat and
driver seat that push up the passenger seat bottom.
 An object, such as a seat cushion, is put on the passenger's seat or between the passenger's
back and the seatback.
 A seat cover is put on the passenger's seat.
 Luggage or other items are placed on the seat with the child in the child-restraint system.
 The seat is washed.
 Liquids are spilled on the seat.
 The passenger seat is moved backward, pushing into luggage or other items placed behind
it.
 Luggage or other items are placed between the passenger seat and driver seat.
 An electric device is put on the passenger's seat.
 An additional electrical device, such as a seat warmer is installed to the surface of the
passenger seat.
The passenger front and side air bags and seat belt pretensioner systems will deactivate if the
passenger air bag deactivation indicator light turns on.
CAUTION
 To assure proper deployment of the front air bag and to prevent damage to the sensor in
the seat cushion:
 Do not place sharp objects on the seat cushion or leave heavy luggage on them.
 Do not spill any liquids on the seats or under the seats.
 To allow the sensors to function pr operly, always perform the following:
 Adjust the seats as far back as possible an d always sit upright against the seatbacks with
seat belts worn properly.
 If you place your child on the passenger seat , secure the child-restraint system properly
and slide the passenger seat as far back as possible.

NOTE
The system requires about 10 seconds to alternate between turning the passenger front
and side air bags and seat belt pretensioner system on or off.
The passenger air bag deactivation indicator light may turn on repeatedly if luggage or
other items are put on the passenger seat, or if the temperature of the vehicle's interior
changes suddenly.
The passenger air bag deactivation indicator light may turn on for 10 seconds if the
electrostatic capacity on the passenger seat changes.
The air bag/seat belt pretensioner system wa rning light might turn on if the passenger
seat receives a severe impact.
If the passenger air bag deactivation indicator light does not turn on after installing a
child-restraint system on the passenger seat, first, re-install your child-restraint system
according to the procedure in this owner's manual. Then, if the passenger air bag
deactivation indicator light still does not turn on, and consult an Authorized Mazda
Dealer as soon as possible.
If the passenger air bag deactivation indicato r light turns on when an occupant is seated
directly in the passenger seat, have the passenger re-adjust their posture by sitting with
their feet on the floor, and then re-fasteni ng the seat belt. If the passenger air bag
deactivation indicator light remains turned on, slide the passenger seat as far back as
possible. Consult an Authorized Mazda Dealer as soon as possible.
