Properly dispose of the air bag system:
Improper disposal of an air bag or a vehicle with live air bags in it can be extremely
dangerous. Unless all safety procedures are followed, injury could result. Have an Authorized
Mazda Dealer safely dispose of the air bag sy stem or scrap an air bag equipped vehicle.
NOTE
If it becomes necessary to have the components or wiring system for the supplementary
restraint system modified to accommodate a person with certain medical conditions in
accordance with a certified physician, contact an Authorized Mazda Dealer, refer to
“Customer Assistance (U.S.A.)” (page 8-2).
When an air bag deploys, a loud inflation noise can be heard and some smoke will be
released. Neither is likely to cause injury, however, the text ure of the air bags may cause
light skin injuries on body parts not covered with clothing through friction.
Should you sell your Mazda, we urge you to tell the new owner of its air bag systems and
that familiarization with all instructions about them, from the Owner's Manual, is
important.
This highly-visible label is displayed wh ich warns against the use of a rear-facing
child-restraint system on the front passenger seat.

Front Passenger Occupant Classification System*
First, please read "Supplemental Restraint System (SRS) Precautions" (page 2-44) carefully.
▼Front Passenger Occupant Classification Sensor
Your vehicle is equipped with a front passenger occupant classi
fication sensor as a part of
the supplemental restraint system. This sensor is equipped in t he front passenger's seat
cushion. This sensor measures th e electrostatic capacity of the front passenger's seat. The
SAS unit is designed to prevent the front passenger front and s ide air bags and seat belt
pretensioner system from deployi ng if the front passenger air bag deactivation indicator
light turns on.
To reduce the chance of injuries caused by deployment of the front passenger air bag, the
system deactivates the front passenger front and side air bags and also the seat belt
pretensioner system when the front passenger air bag deactivati on indicator light turns on.
Refer to the following table for the front passenger air bag deactivation indicator light
illumination conditions.

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

The air bag/front seat belt pretensioner system warning light f lashes and the front passenger
air bag deactivation indicator light illuminates if the sensors have a possible malfunction. If
this happens, the front passenger front and side air bags and s eat belt pretensioner system
will not deploy.
Front passenger air bag deactivation indicator light
This indicator light turns on to r emind you that the front passenger front and side air bags
and seat belt pretensioner will not deploy during a collision.
If the front passenger occupant classification sensor is normal, the indicator light turns on
when the ignition is switched ON. The light turns off after a f ew seconds. Then, the
indicator light turns on or is off under the following conditio ns:

deactivation indicator light on/off condition chart indicates.
If the front passenger air bag deactivation indicator light doe s not turn on when the ignition
is switched ON and does not turn on as indicated in the front p assenger air bag deactivation
indicator light on/off condition chart, do not allow an occupan t to sit in the front passenger
seat and consult an Authorized M azda Dealer as soon as possible. The system may not work
properly in an accident.
WA R N I N G
Do not allow an occupant in the front passenger's seat to sit with a posture which makes it
difficult for the front passenger occupant classification sensor to detect the occupant
correctly:
Sitting in the front passenger's seat with a posture which makes it difficult for the front
passenger occupant classification sensor to detect the occupant correctly is dangerous. If the
front passenger occupant classification sensor cann ot detect the occupant sitting on the front
passenger's seat correctly, the front passenger front and side air bags and pretensioner system
may not operate (non-deploy) or they may oper ate (deploy) accidentally. The front passenger
will not have the supplementary protection of the air bags or the accidental operation
(deployment) of the air bags could result in serious injury or death.
Under the following conditions, the front passe nger occupant classification sensor cannot
detect a passenger sitting on the front pa ssenger's seat correctly and the deployment/
non-deployment of the air bags cannot be controlled as indicated in the front passenger air
bag deactivation indicator light on/off condition chart. For example:

CAUTION
To assure proper deployment of the front air bag and to prevent damage to the sensor in
the front seat cushion:
 Do not place sharp objects on the front seat cushion or leave heavy luggage on them.
 Do not spill any liquids on the front seats or under the front seats.
 To allow the sensors to function pr operly, always perform the following:
 Adjust the front seats as far back as possibl e and always sit upright against the seatbacks
with seat belts worn properly.
 If you place your child on the front passenger seat, secure the child-restraint system
properly and slide the fron t passenger seat as far back as possible (page 2-33).
NOTE
The system requires about 10 seconds to alte rnate between turning the front passenger
front and side air bags and seat belt pretensioner system on or off.
The front passenger air bag deactivation indicato r light may turn on repeatedly if luggage
or other items are put on the front passenger seat, or if the temperature of the vehicle's
interior changes suddenly.
The front passenger air bag deactivation indicato r light may turn on for 10 seconds if the
electrostatic capacity on the front passenger seat changes.
The air bag/front seat belt pretensioner system warning light might turn on if the front
