If your vehicle is also equipped with a front passenger occupant classifi cation system,
refer to the Front Passenger Occupant Classifi cation System (page 2-57 ) for details.
If your vehicle is equipped with a front passenger occupant classifi cation system, the front
passenger air bag deactivation indicator light illuminates for a specifi\
ed time after the
ignition is switched ON.
Small children must be protected by a child-restraint system as stipulat\
ed by law in every
state and province. In certain states and provinces, larger children must use a child-restraint
system (page 2-23 ).
Carefully consider which child-restraint system is necessary for your ch\
ild and follow
the installation directions in this Owner's Manual as well as the child-\
restraint system
manufacturer's instructions.
WARNING
Seat belts must be worn in air bag equipped vehicles: Depending only on the air bags for protection during an accident is dangerous. Alone,
air bags may not prevent serious injuries. The appropriate air bags can be expected to
infl ate only in the fi rst accident, such as frontal, near frontal or side collisions or roll-over
accidents that are at least moderate. Vehicle occupants should always wear seat belts.

Children should not ride in the front passenger seat: Placing a child, 12 years or under, in the front seat is dangerous. The child could be hit
by a deploying air bag and be seriously injured or even killed. A sleeping child is more
likely to lean against the door and be hit by the side air bag in moderate collision to the
front-passenger side of the vehicle. Whenever possible, always secure a child 12 years and
under on the rear seats with an appropriate child-restraint system for the child's age and
size.

First, please read "Supplemental Restraint System (SRS) Precautions" (page 2-41 ) 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.

 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.

ont seat belts are
