Never use a rear-facing child-restraint system in the front seat with an air bag that could
deploy:
Rear-facing child-restraint systems on the front seat are particularly dangerous even though
you may feel assured that a front passenger air bag will not deploy based on the fact that the
front passenger air bag deactivation indicator light illuminates. The child-restraint system
can be hit by a deploying air bag and moved viol ently backward resulting in serious injury or
death to the child.
Do not sit too close to the driver and front passenger air bags:
Sitting too close to the driver and front passenger air bag modules or placing hands or feet on
them is extremely dangerous. The driver and front passenger air bags inflate with great force
and speed. Serious injuries could occur if someon e is too close. The driver should always hold
onto only the rim of the steering wheel. The front seat passenger should keep both feet on the
floor. Front seat occupants should adjust their seats as far back as possible and always sit
upright against the seatbacks with seat belts worn properly.
Sit in the center of the seat and wear seat belts properly:
Sitting too close to the side air bag modules or placing hands on them, or sleeping up against
the door or hanging out the windows is extrem ely dangerous. The side and curtain air bags
inflate with great force and speed directly expanding
along the door on the side the car is hit.
Serious injury could occur if someone is sitting too close to the door or leaning against a
window, or if rear seat occupants grab the side s of the front seatbacks. Give the side and
curtain air bags room to work by sitting in th e center of the seat while the vehicle is moving
with seat belts worn properly.
Do not attach objects on or around the area where air bags deploy:
Attaching objects to the air bags or placing so mething in the area where the air bags deploy
is dangerous. In an accident, an object could interfere with air bag inflation and injure the
occupants. Furthermore, the bag could be damaged causing gases to release. Always keep
the deployment area of the air bag modules free of any obstructions.
For example, you should not do any of the following as it may interfere with air bag
deployment.
 Do not put a covering on or lean anything against areas such as the dashboard and lower
portion of the instrument panel that blocks the passenger front air bag and knee air bags.
 Do not use seat covers on the front seats and re ar seats equipped with in-seat side air bags.

Do not modify a front door or leave any damage unrepaired. Always have an Authorized
Mazda Dealer inspect a damaged front door:
Modifying a front door or leaving any damage unrepaired is dangerous. Each front door has a
side crash sensor as a component of the supplemental restraint system. If holes are drilled in a
front door, a door speaker is left removed, or a damaged door is left unrepaired, the sensor
could be adversely affected causing it to not detect the pressure of an impact correctly during
a side collision. If a sensor does not detect a side impact correctly, the side and curtain air
bags and the front seat belt pretensioner may not operate normally which could result in
serious injury to occupants.
Do not modify the supplemental restraint system:
Modifying the components or wiri ng of the supplemental restraint system is dangerous. You
could accidentally activate it or make it inoperable. Do not make any modifications to the
supplemental restraint system. This includes inst alling trim, badges, or anything else over the
air bag modules. It also includes installing extra electrical equipment on or near system
components or wiring. An Authorized Mazda Dealer can provide the special care needed in
the removal and installation of front seats. It is important to protect the air bag wiring and
connections to assure that the bags do not accidentally deploy, and that the front passenger
occupant classification system and the seats retain an undamaged air bag connection.
Do not place luggage or other objects under the front seats:
Placing luggage or other objects under th e front seats is dangerous. The components
essential to the supplemental restraint system could be damaged, and in the event of a side
collision, the appropriate air bags may not de ploy, which could result in death or serious
injury. To prevent damage to the components essential to the supplemental restraint system,
do not place luggage or other objects under the front seats.
Do not operate a vehicle with damaged air bag/seat belt pretensioner system components:
Expended or damaged air bag/seat belt preten sioner 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 dama ged 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 injuri es. Always have an Authorized Mazda Dealer
remove these parts.

How the SRS Air Bags Work
Your Mazda is equipped with the following types of SRS air bags. SRS air bags are
designed to work together with the seat belts to help to reduce injuries during an accident.
The SRS air bags are designed to provide further protection for passengers in addition to the
seat belt functions. Be sure to wear seat belts properly.
▼ Front Seat Belt Pretensioners
The front seat belt pretensioners are designed to deploy in mod
erate or severe frontal, near
frontal collisions.
In addition, the pretensioners ope rate when a side collision or a roll-over accident is
detected. The pretensioners operate differently depending on wh at types of air bags are
equipped. For more det ails about seat belt pretensioner operati on, refer to the SRS Air Bag
Deployment Criteria (page 2-81).
▼ Driver Air Bag
The driver's air bag is mounted in the steering wheel.
When air bag crash sensors detect a frontal impact of greater than moderate force, the
driver's air bag inflates quickly
helping to reduce injury mainly to the driver's head or chest
caused by directly hitting the steering wheel.
For more details about air bag deployment, refer to "SRS Air Ba g Deployment Criteria"
(page 2-81).
(With Front Passenger Occupa nt Classification System)
The driver's dual-stage air bag controls air bag inflation in two energy stages. During an
impact of moderate severity, the driver's air bag deploys with lesser energy, whereas during
more severe impacts, it deploys with more energy.

Front Passenger Occupant Classification System*
First, please read "Supplemental Restraint System (SRS) Precaut ions" (page 2-69) carefully.
▼Front Passenger Occupant Classification Sensor
Your vehicle is equipped with a front passenger occupant classi
fication 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 deployin g if the front passenger air bag deactivation indicator
light turns on.
To reduce the chance of injuries caused by deployment of the fr ont 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 deactivati on indicator light turns on.
Refer to the following table fo r the front passenger air bag de activation 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 f lashes and the front passenger
air bag deactivation indicator li ght illuminates if the sensors have a possible malfunction. If
this happens, the front passenger front and side air bags and s eat belt pretensioner system
will not deploy.
Front passenger air bag de activation indicator light
This indicator light turns on to remind you that the front pass enger front and side air bags
and seat belt pretensioner wil l not deploy during a collision.

depending on the person's physique.
The curtain air bag is ready for inflating regardless of what the front passenger air bag
deactivation indicator light on/ off condition chart indicates.
If the front passenger air bag d eactivation indicator light does not turn on when the ignition
is switched ON and does not turn on as indicated in the front p assenger air bag deactivation
indicator light on/off condition chart, do not allow an occupan t 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.
WA R N I N G
Do not allow an occupant in the front passenger's seat to sit with a posture which makes it
difficult for the front passenger occupant classification sensor to detect the occupant
correctly:
Sitting in the front passenger's seat with a posture which makes it difficult for the front
passenger occupant classification sensor to dete ct the occupant correctly is dangerous. If the
front passenger occupant classification sensor cannot detect the occupant sitting on the front
passenger's seat correctly, the front passeng er front and side air bags and pretensioner
system may not operate (non-deploy) or they may operate (deploy) accidentally. The front
passenger will not have the supplementary prot ection 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 classification 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:

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
 To assure proper deployment of the front air bag and to prevent damage to the sensor in
the front seat cushion:
 Do not place sharp objects on the front seat cushion or leave heavy luggage on them.
 Do not spill any liquids on the fr ont seats or under the front seats.
 To allow the sensors to function pr operly, always perform the following:
 Adjust the front seats as far back as possibl e and always sit upright against the seatbacks
with seat belts worn properly.
 If you place your child on the front passe nger seat, secure the child-restraint system
properly and slide the front passenger seat as far back as possible (page 2-60).
NOTE
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.
The front passenger air bag deactivation indicator light may turn on repeatedly if luggage
or other items are put on the front passenger se at, or if the temperature of the vehicle's
interior changes suddenly.
The front passenger air bag deactivation indicator light may turn on for 10 seconds if the
electrostatic capacity on the front passenger seat changes.
The air bag/front seat belt pr etensioner system warning light might turn on if the front
passenger seat receives a severe impact.
If the front passenger air bag deactivation indicator light does not turn on after installing
a child-restraint system on the front passenger seat, first, 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.
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 floor, 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.
