Limitations to SRS Air Bag
In severe collisions such as those described previously in "SRS Air Bag Deployment
Criteria", the applicable SRS air bag equipment will deploy. However, in some accidents,
the equipment may not deploy depending on the type of collision and its severity.

Limitations to front/near front collision detection:
The following illustrations are examples of front/near front collisions that may not be
detected as severe enough to deploy the SRS air bag equipment.

Roll-over (Without Front Passenger Occupant Classification System)

(With Front Passenger Occupant Classi¿ cation System)
Limitations to roll-over detection:
The following illustration is an example of an accident that may not be detected as a roll-
over accident. Therefore, the front seat belt pretensioners and curtain air bags may not
deploy.

Front Passenger Occupant Classi¿ cation System
First, please read "Supplemental Restraint System (SRS) Precautions" (page 2-38 )
carefully.
Front Passenger Occupant Classi¿ cation Sensor
Your vehicle is equipped with a front passenger occupant classi¿ cation sensor as a part
of the supplemental restraint system. This sensor is equipped in the front passenger's seat
cushion. This sensor measures the electrostatic capacity of the front passenger's seat. The
SAS unit is designed to prevent the front passenger front and side air bags and seat belt
pretensioner system from deploying 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 deactivation 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 bags 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 À ashes 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 seat belt pretensioner system
will not deploy.
Front passenger air bag deactivation indicator light
This indicator light turns on to remind 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 classi¿ cation sensor is normal, the indicator light turns
on when the ignition is switched ON. The light turns off after a few seconds. Then, the
indicator light turns on or is off under the following conditions:

*1 The occupant classi¿ cation sensor may not detect a child seated on the seat, in a child-restraint system, or a
junior seat depending on the child's physical size and seated posture.
*2 If a smaller adult sits on the front passenger seat, the sensors might detect the person as being a child depending
on the person's physique.


The curtain air bag is ready for inÀ ating regardless of what the front passenger air bag
deactivation indicator light on/off condition chart indicates.
If the front passenger air bag deactivation indicator light does not turn on when the ignition
is switched ON and does not turn on as indicated in the front passenger air bag deactivation
indicator light on/off condition chart, do not allow an occupant to sit in the front passenger
seat and consult an Authorized Mazda Dealer as soon as possible. The system may not work
properly in an accident.

WARNING
Do not allow an occupant in the front passenger's seat to sit with a posture which
makes it diffi cult for the front passenger occupant classifi cation sensor to detect the
occupant correctly:
Sitting in the front passenger's seat with a posture which makes it diffi cult for the front
passenger occupant classifi cation sensor to detect the occupant correctly is dangerous.
If the front passenger occupant classifi cation sensor cannot 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 (deploy) or they may operate (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 passenger occupant classifi cation sensor
cannot detect a passenger sitting on the front passenger'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:




¾ A front passenger is seated as shown in the following fi gure:


%:A(*'#'A'FKVKQPKPFD%:A(*'#'A'FKVKQPKPFD

¾ A rear passenger pushes up on the front passenger seat with their feet.



¾ Luggage or other items placed under the front passenger seat or between the front
passenger seat and driver seat that push up the front passenger seat bottom.
 


¾ An object, such as a seat cushion, is put on the front passenger's seat or between the
passenger's back and the seatback.
 


¾ A seat cover is put on the front passenger's seat.



¾ Luggage or other items are placed on the seat with the child in the child-restraint
system.
 


¾ A rear passenger or luggage push or pull down on the front passenger seatback.



¾ Luggage or other items are placed on the seatback or hung on the head restraint.



¾ The seat is washed.



¾ Liquids are spilled on the seat.



¾ The front passenger seat is moved backward, pushing into luggage or other items
placed behind it.
 


¾ The front passenger seatback contacts the rear seat.



¾ Luggage or other items are placed between the front passenger seat and driver seat.



¾ An electric device is put on the front passenger's seat.



¾ An additional electrical device, such as a seat warmer is installed to the surface of the
front passenger seat.

The front passenger front and side air bags and seat belt pretensioner systems will
deactivate if the front passenger air bag deactivation indicator light turns on.

CAUTION
 


¾ To assure proper deployment of the front air bag and to prevent damage to the sensor in
the front seat cushion:
 


¾ Do not place sharp objects on the front seat cushion or leave heavy luggage on them.



¾ Do not spill any liquids on the front seats or under the front seats.

 


¾ To allow the sensors to function properly, always perform the following: 



¾ Adjust the front seats as far back as possible and always sit upright against the
seatbacks with seat belts worn properly.
 


¾ If you place your child on the front passenger seat, secure the child-restraint system
properly and slide the front passenger seat as far back as possible (page 2-27 ).

y The system requires about 10 seconds to alternate between turning the front passenger
front and side air bags and seat belt pretensioner system on or off.
 


y The front passenger air bag deactivation indicator 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.
 


y The front passenger air bag deactivation indicator light may turn on for 10 seconds if the
electrostatic capacity on the front passenger seat changes.
 


y The air bag/front seat belt pretensioner system warning light might turn on if the front
passenger seat receives a severe impact.
 


y If the front passenger air bag deactivation indicator light does not turn on after installing
a child-restraint system on the front passenger seat, ¿ rst, re-install your child-restraint
system according to the procedure in this owner's manual. Then, if the front passenger air
bag deactivation indicator light still does not turn on, install the child-restraint system on
the rear seat and consult an Authorized Mazda Dealer as soon as possible.
 


y If the front passenger air bag deactivation indicator light turns on when an occupant
is seated directly in the front passenger seat, have the passenger re-adjust their posture
by sitting with their feet on the À oor, and then re-fastening the seat belt. If the front
passenger air bag deactivation indicator light remains turned on, move the passenger to
the rear seat. If sitting in the rear seat is not possible, slide the front passenger seat as far
back as possible. Consult an Authorized Mazda Dealer as soon as possible.
