Do not leave a seat belt extender
connected to the buckle:Leaving a seat belt extender
connected to the buckle without
using the seat belt is dangerous.
When the seat belt extender is
connected to the driver's seat belt
buckle (or front passenger) seat, the
SRS driver's (or front passenger's) air
bag system will determine that the
driver (or front passenger) is wearing
the seat belt even if the driver (or
front passenger) is not wearing it.
This condition could cause the
driver's (or front passenger's) air bag
to not activate correctly and result in
death or serious injury in the event of
collision. Always wear the seat belt
with the seat belt extender.
Do not use the seat belt extender when
installing a child-restraint system on
the front or rear passenger seat: Using a seat belt extender to fasten a
child-restraint system on any seat is
dangerous. Always follow the child-
restraint system manufacturer's
installation instructions and never
use a seat belt extender.
NOTE
When not in use, remove the seat belt extender
and store it in the vehicle. If the seat belt
extender is left connected, the seat belt
extender might get damaged as it will not
retract with the rest of the seat belt and can
easily fall out of the door when not in use and
be damaged. In addition, the seat belt warning
light will not illuminate and function properly.
Seat Belt Warning Light
With warning light for front
passenger's seat
The seat belt warning light illuminates if
the driver or front passenger's seat belt is
not fastened (only when the front
passenger seat is occupied) when the
ignition is switched ON.
Without warning light for front
passenger's seat
The seat belt warning light illuminates if
the driver's seat belt is not fastened when
the ignition is switched ON.

Seating a child in a child-restraint system on the front passenger seat is dangerous
under certain conditions (With Driver and Front Passenger Occupant Classification
System):Your vehicle is equipped with front passenger seat weight sensors. Even with the
front passenger seat weight sensors, if you must use the front passenger seat to seat
a child, using a child-restraint system on the front passenger seat under the
following conditions increases the danger of the front passenger air bag deploying
and could result in serious injury or death to the child.
ØThe front passenger air bag deactivation indicator light does not illuminate when
seating a child in the child-restraint system.
Ø Luggage or other items are placed on the seat with the child in the child-restraint
system.
Ø A rear passenger or luggage pushing or pulling down on the front passenger
seatback.
Ø A rear passenger puts their feet on the front seat rails.
Ø Luggage or other items are placed on the seatback or hung on the head restraint.
Ø Heavy items are placed in the seatback map pocket.
Ø The seat is washed.
Ø Liquids are spilled on the seat.
Ø The front passenger seat is moved backward, pushing into luggage or other items
placed behind it.
Ø The front passenger seatback contacts the rear seat.
Ø Luggage or other items are placed between the front passenger seat and driver
seat.
Ø Any accessories, which might increase the total seated weight on the front
passenger seat, are attached to the front passenger seat.
The designated positions with seat belts on the rear seats are the safest places for
children. Always use seat belts and child restraints.
Do not allow a child or anyone to lean over or against the side window of a vehicle
with side and curtain air bags: It is dangerous to allow anyone to lean over or against the side window, the area of
the front passenger seat, the front and rear window pillars and the roof edge along
both sides from which the side and curtain air bags deploy, even if a child-restraint
system is used. The impact of inflation from a side or curtain air bag could cause
serious injury or death to an out of position child. Furthermore, leaning over or
against the front door could block the side and curtain air bags and eliminate the
advantages of supplemental protection. With the front air bag and the additional
side air bag that comes out of the front seat, the rear seat is always a better location
for children. Take special care not to allow a child to lean over or against the side
window, even if the child is seated in a child-restraint system.

Driver and Front Passenger Occupant Classification Systemí
First, please read“Supplemental Restraint System (SRS) Precautions ”(page 2-44)
carefully.
q Driver Seat Slide Position Sensor
Your vehicle is equipped with a driver seat slide position sensor as a part of the
supplemental restraint system. The sensor is located under the driver seat. The sensor
determines whether the driver seat is fore or aft of a reference position and sends the seat
position to the diagnostic module (SAS unit). The SAS unit is designed to control the
deployment of the driver air bag depending on how close the driver seat is to the steering
wheel.
The air bag/front seat belt pretensioner system warning light flashes if the sensor has a
possible malfunction (page 2-53).
qFront Passenger Seat Weight Sensors
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 seat 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 system from
deploying if the front passenger air bag deactivation indicator light illuminates.
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
illuminates. 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 illuminates
according to the following table.
The air bag/front seat belt pretensioner system warning light flashes 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.

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:
ØA rear passenger pushes up on the front passenger seat with their feet.
Ø 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.
Ø The front passenger seat occupant sits in a manner that does not place the entire
weight of the occupant on the seat such as by sitting too close to the door,
grasping the assist grip or the rim of the moonroof and sitting with the seatback
reclined too far.
Ø Any accessories which might decrease the total seated weight on the front
passenger seat are attached to 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 illuminates.

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:
ØLuggage or other items are placed on the seat with the child in the child-restraint
system.
Ø A rear passenger or luggage push or pull down on the front passenger seatback.
Ø A rear passenger steps on the front passenger seat rails with their feet.
Ø Luggage or other items are placed on the seatback or hung on the head restraint.
Ø Heavy items are placed in the seatback map pocket.
Ø The seat is washed.
Ø Liquids are spilled on the seat.
Ø The front passenger seat is moved backward, pushing into luggage or other items
placed behind it.
Ø The front passenger seatback contacts the rear seat.
Ø Luggage or other items are placed between the front passenger seat and driver
seat.
Ø Any accessories which might increase the total seated weight on the front
passenger seat are attached to 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 illuminates.
CAUTION
Ø To assure proper deployment of the front air bag and to prevent damage to the
sensors in the front seat bottoms:
ØDo not place sharp objects on the front seat bottoms or leave heavy luggage on
them.
ØDo not spill any liquids on the front seats or under the front seats.
Ø To allow the sensors to function properly, always perform the following:
ØAdjust the front seats as far back as possible and always sit upright against the
seatbacks with seat belts worn properly.
ØIf 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
2-36).

WARNING
Do not operate a vehicle with damaged air bag/seat belt pretensioner system
components:Expended or damaged air bag/seat belt pretensioner system components must be
replaced after any collision which caused them to deploy or damage them. Only a
trained Authorized Mazda Dealer can fully evaluate these systems to see that they
will work in any subsequent accident. Driving with an expended or damaged air bag
or pretensioner unit will not afford you the necessary protection in the event of any
subsequent accident which could result in serious injury or death.
Do not remove interior air bag parts: Removing any components such as the front seats, front dashboard, the steering
wheel or parts on the front and rear window pillars and along the roof edge,
containing air bag parts or sensors is dangerous. These parts contain essential air
bag components. The air bag could accidentally activate and cause serious injuries.
Always have an Authorized Mazda Dealer remove these parts.
Dispose of the air bag properly: 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 can result. Ask an
Authorized Mazda Dealer how to safely dispose of an air bag or how to 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 9-2).
