Passenger Occupant Classification System*
First, please read "Supplemental Restraint System (SRS) Precaut ions" (page 2-26) carefully.
▼Passenger Occupant Classification Sensor
Your vehicle is equipped with a p
assenger occupant classification 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 bag deactivation indicator light turns on.
To reduce the chance of injuries caused by deployment of the pa ssenger 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 pretensioner system warning light flashes and the passenger air bag
deactivation indicator light illuminates 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.
If the passenger occupant classi fication sensor is normal, the indicator light turns on when
the ignition is switched ON. The light t urns off after a few seconds. Then, the indicator light
turns on or is off under the following conditions:

junior seat depending on the ch ild's physical size and seated posture.
*2 If a smaller adult sits on the passenger seat, the sensors might detect the person as being a child depending on
the person's physique.
If the passenger air bag deactivat ion 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
indicator light on/off condition chart, do not allow an occupan t to sit in the passenger seat
and consult an Authorized Mazda 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 passenger's seat to sit with a posture which makes it difficult
for the passenger occupant classification sensor to detect the occupant correctly:
Sitting in the passenger's seat with a posture which makes it difficult for the passenger
occupant classification sensor to detect the occupant correctly is dangerous. If the passenger
occupant classification sensor cannot detect the occupant sitting on the passenger's seat
correctly, the passenger front and side air ba gs and pretensioner system may not operate
(non-deploy) or they may operate (deploy) a ccidentally. The passenger will not have the
supplementary protection of the air bags or th e accidental operation (deployment) of the air
bags could result in serious injury or death.
Under the following conditions, the passenger occu pant classification sensor cannot detect a
passenger sitting on the passenger's seat co rrectly and the deployment/non-deployment of
the air bags cannot be controlled as indicated in the 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 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 indicato r 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 warning light might turn on if the passenger
seat receives a severe impact.
If the passenger air bag deactivation indicato r 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 indicator 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-fastening 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.

WA R N I N G
Do not leave the key in your vehicle with
children and keep them in a place where
your children will not find or play with
them:
Leaving children in a vehicle with the key is
dangerous. This could result in someone
being badly injured or even killed. Children
may find these keys to be an interesting toy
to play with and could cause the power
windows or other controls to operate, or
even make the vehicle move.
CAUTION
Because the key (transmitter) uses
low-intensity radio waves, it may not
function correctly under the following
conditions:
 The key is carried with communication
devices such as cellular phones.
 The key contacts or is covered by a
metal object.
 The key is near electronic devices such
as personal computers.
 Non-Mazda genuine electronic
equipment is installed in the vehicle.
 There is equipment which discharges
radio waves near the vehicle.
 The key (transmitter) may consume
battery power excessively if it receives
high-intensity radio waves. Do not place
the key near electronic devices such as
televisions or personal computers.
 To avoid damage to the key
(transmitter), DO NOT:
 Drop the key.
 Get the key wet.
 Disassemble the key.
 Expose the key to high temperatures
on places such as the dashboard or
hood, under direct sunlight.
 Expose the key to any kind of magnetic
field.
 Place heavy objects on the key.
