The front passenger front and side air bags and the seat belt pretension\
er are designed to deploy depending on the condition of the total seated weight on the fron\
t passenger seat.

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.
Impacts involving trees or polesFrontal offset impact to the vehicle

First, please read "Supplemental Restraint System (SRS) Precautions" (page 2-40 ) carefully.
Front Passenger Seat Weight Sensor
Your vehicle is equipped with a front passenger seat weight sensors as a \
part of the
supplemental restraint system. These sensors are located under both of the front passenger
seat rails. These sensors determine the total seated weight on the front passenger s\
eat and
monitor the seat belt buckle for the front passenger seat. The SAS unit is designed to prevent
the front passenger front and side air bags and seat belt pretensioner s\
ystem from deploying
if the front passenger air bag deactivation indicator light illuminates.\
To reduce the chance of injuries caused by deployment of the front passen\
ger air bag,
the system deactivates the front passenger front and side air bags and a\
lso the seat
belt pretensioner system when the front passenger air bag deactivation i\
ndicator light
illuminates. Refer to the following table for the front passenger air ba\
g 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 illuminates
according to the following table.
The air bag/front seat belt pretensioner system warning light fl ashes and the front passenger
air bag deactivation indicator light illuminates if the sensors have a p\
ossible malfunction.
If this happens, the front passenger front and side air bags and seat be\
lt pretensioner system
will not deploy.
Front passenger air bag deactivation indicator light
This indicator light illuminates 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 weight sensors are normal, the indicator light il\
luminates when the
ignition is switched ON. The light turns off after a few seconds.
The front/passenger air bag deactivation indicator light illuminates or \
is off under the
following conditions:

*2 Off Ready Ready
*1 If a larger child sits on the front passenger seat, the sensors might detect the\
child as being an adult depending on the child's physique.
*2 If a smaller adult sits on the front passenger seat, the sensors might d\
etect the person as being a child depending on the person's physique.
The curtain air bag is ready for infl ating regardless of the chart above.
If the front passenger air bag deactivation indicator light does not ill\
uminate when the
ignition is switched ON and does not illuminate as indicated in the abov\
e chart, do not allow
a child 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 decrease the total seated weight on the front passenger seat: When an adult or large child sits on the front passenger seat, decreasing the total seated
weight on the front passenger seat required for air bag deployment is dangerous. The
front passenger seat weight sensors will detect the reduced total seated weight condition
and the front passenger front and side air bags and seat belt pretensioner system will
not deploy during an accident. The front passenger will not have the supplementary
protection of the air bag, which could result in serious injury. Decreasing the total seated
weight on the front passenger seat could result in an air bag not deploying under the
following conditions, for example:

Do not increase the total seated weight on the front passenger seat: When an infant or small child sits on the front passenger seat, increasing the total seated
weight on the front passenger seat is dangerous. The front passenger seat weight sensors
will detect the increased total seated weight, which could result in the unexpected
deployment of the front passenger front and side air bags and seat belt pretensioner
system in an accident and may cause serious injury. Increasing the total seated weight on
the front passenger seat could result in the front passenger front and side air bags and
seat belt pretensioner system deployment in an accident under the following conditions,
for example:

NOTE
 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 illuminate 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 illuminate for 10\
seconds if
the total seated weight on the front passenger seat changes.
 y The air bag/front seat belt pretensioner system warning light might illuminate if the front
passenger seat receives a severe impact.
 y If the front passenger air bag deactivation indicator light does not illuminate a\
fter
installing a child-restraint system on the front passenger seat, fi 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 illuminate\
, 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 illuminates when an a\
dult is
seated in the front passenger seat, have the passenger re-adjust their posture by sitting
with their feet on the fl oor, and then re-fastening the seat belt. If the front passenger air
bag deactivation indicator light still illuminates, move the passenger t\
o 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.
Driver and Front Passenger Buckle Switches
The buckle switches on the front seat belts detect whether or not the fr\
ont seat belts are
securely fastened and further control the deployment of the air bags.
