To prevent false detection by the air bag sensor system, heed the following:  


 Do not use tires or wheels other than those specifi ed for your Mazda:
 Use of any tire or wheel other than those specifi ed for your Mazda (page 9-9 ) is
dangerous. Use of such wheels will prevent the vehicle's accident detections system
from accurately detecting a collision or roll-over accident resulting in incorrect or
unexpected air bag deployment and the possibility of serious injuries.
 


 Do not overload your vehicle:
 Overloading your vehicle is dangerous as it could prevent the air bag crash sensor
system from accurately detecting a collision or roll-over accident resulting in incorrect
or unexpected air bag deployment and the possibility of serious injuries. The gross axle
weight rating (GAWR) and the gross vehicle weight rating (GVWR) for your vehicle are
on the Motor Vehicle Safety Standard Label on the driver's door frame. Do not exceed
these ratings.
 


 Do not drive the vehicle off -road:
 Driving your Mazda off -road is dangerous because the vehicle has not been designed
to do so. Driving the vehicle off -road could prevent the air bag crash sensor system
from accurately detecting a collision or roll-over accident resulting in incorrect or
unexpected air bag deployment and the possibility of serious injuries.
 




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 aff ected 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 wiring of the supplemental restraint system is dangerous.
You could accidentally activate it or make it inoperable. Do not make any modifi cations
to the supplemental restraint system. This includes installing 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 classifi cation system and the seats retain an undamaged
air bag connection.

SRS Air Bags
Do not place luggage or other objects under the front seats:
Placing luggage or other objects under the 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 deploy, 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 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 aff ord 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.

Properly dispose of the air bag system:
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 could result. Have an
Authorized Mazda Dealer safely dispose of the air bag system or scrap an air bag
equipped vehicle.

SRS Air Bags
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 moderate or severe frontal, near
frontal collisions.
In addition, the pretensioners operate when a side collision (only on the side in which the
collision occurs) or a roll-over accident is detected. The pretensioners operate differently
depending on what types of air bags are equipped. For more details about seat belt
pretensioner operation, refer to the SRS Air Bag Deployment Criteria (page 2-62 ).
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 infl ates 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 Bag Deployment Criteria"
(page 2-62 ).
(With Front Passenger Occupant Classifi cation System)
The driver's dual-stage air bag controls air bag infl ation 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.

SRS Air Bags
Front Passenger Air Bag
The front passenger air bag is mounted in the front passenger dashboard.
The infl ation mechanism for the front passenger air bag is the same as the driver's air bag.
For more details about air bag deployment, refer to "SRS Air Bag Deployment Criteria"
(page 2-62 ).
(With Front Passenger Occupant Classifi cation System)
In addition, the front passenger air bag is designed to only deploy when the front passenger
occupant classifi cation sensor detects a passenger sitting on the front passenger's seat. For
details, refer to the front passenger occupant classifi cation system (page 2-65 ).

Essential Safety Equipment
SRS Air Bags
Side Air Bags
The side air bags are mounted in the outboard sides of the front seatbacks.
When the air bag crash sensors detect a side impact of greater than moderate force, the
system infl ates the side air bag only on the side in which the vehicle was hit. The side
air bag infl ates quickly to reduce injury to the driver or front passenger's chest caused by
directly hitting interior parts such as a door or window.
For more details about air bag deployment, refer to "SRS Air Bag Deployment Criteria"
(page 2-62 ).
(With Front Passenger Occupant Classifi cation System)
In addition, the front passenger side bag is designed to only deploy when the front passenger
occupant classifi cation sensor detects a passenger sitting on the front passenger's seat. For
details, refer to the front passenger occupant classifi cation system (page 2-65 ).

Essential Safety Equipment
SRS Air Bags
Curtain Air Bags
The curtain air bags are mounted in the front and rear window pillars, and the roof edge
along both sides.
When the air bag crash sensors detect a side impact of greater than moderate force, the
curtain air bag infl ates quickly and helps to reduce injury mainly to the rear outboard
passenger's head caused by directly hitting interior parts such as a door or window.
For more details about air bag deployment, refer to "SRS Air Bag Deployment Criteria"
(page 2-62 ).
In a side impact:
Greater than moderate impact to one side of the vehicle will cause the curtain air bag on that
side only to infl ate.

Only one side curtain air bag will deploy on the
side of the vehicle that receives the force of an
impact.

(With Front Passenger Occupant Classifi cation System)
In a roll-over:
In response to a vehicle roll-over, both curtain air bags infl ate.


Both curtain air bags will deploy after
the roll-over accident is detected.
