First, please read "Supplementary Restraint System (SRS) Precautions" (page 2-33 )
carefully.
Passenger Occupant Classi¿ cation Sensor
Your vehicle is equipped with a passenger occupant classi¿ cation sensor as a part of the
supplementary restraint system. This sensor is equipped in the passenger's seat cushion. This
sensor measures the electrostatic capacity of the passenger's seat. The SAS unit is designed
to prevent the passenger front and side air bags and seat belt pretensioner system from
deploying if the passenger air bag deactivation OFF indicator light turns on.
To reduce the chance of injuries caused by deployment of the passenger air bag, the system
deactivates the passenger front and side air bags and also the seat belt pretensioner system
when the passenger air bag deactivation OFF indicator light turns on. Refer to the following
table for the passenger air bag deactivation indicator light illumination conditions.
This system shuts off the passenger front and side air bags and seat belt pretensioner system,
so make sure the passenger air bag deactivation indicator light turns on according to the
following table.
The air bag/seat belt pretensioner system warning light À ashes and the passenger air bag
deactivation OFF indicator light illuminates if the sensors have a possible malfunction. If
this happens, the passenger front and side air bags and seat belt pretensioner system will not
deploy.
Passenger air bag deactivation indicator lights
These indicator lights turn on to remind you that the passenger front and side air bags and
seat belt pretensioner will or will not deploy during a collision.
If the passenger occupant classi¿ cation sensor is normal, both indicator lights turn on when
the ignition is switched ON. The lights turn off after a few seconds. Then, the indicator
lights turn on or off under the following conditions:

junior seat depending on the child's physical size and seated posture.
*2 If a smaller adult sits on the passenger seat, the sensors might detect the person as being a child depending on
the person's physique.
If both of the passenger air bag deactivation indicator lights do not turn on for a speci¿ ed
period of time when the ignition is switched ON or they do not turn on as indicated in
the passenger air bag deactivation indicator light on/off condition chart, do not allow an
occupant to sit in the passenger seat and consult an Authorised Mazda Repairer as soon as
possible. The system may not work properly in an accident.

WARNING
Do not allow an occupant in the passenger's seat to sit with a posture which makes
it dif¿ cult for the passenger occupant classi¿ cation sensor to detect the occupant
correctly:
Sitting in the passenger's seat with a posture which makes it dif¿ cult for the passenger
occupant classi¿ cation sensor to detect the occupant correctly is dangerous. If the
passenger occupant classi¿ cation sensor cannot detect the occupant sitting on the
passenger's seat correctly, the passenger front and side air bags and pretensioner
system may not operate (non-deploy) or they may operate (deploy) accidentally. The
passenger will not have the supplementary protection 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 passenger occupant classi¿ cation sensor cannot
detect a passenger sitting on the passenger's seat correctly and the deployment/non-
deployment of the air bags cannot be controlled as indicated in the passenger air bag
deactivation indicator light on/off condition chart. For example:
 
 A passenger is seated as shown in the following ¿ gure:

Active Bonnet
*Some models.
Active Bonnet precautions *
In the unlikely event that the vehicle were to hit a pedestrian and a certain amount of impact
is applied to the front of the vehicle, impact to the head of the pedestrian if it were to hit the
bonnet is lessened by the rear area of the bonnet raising instantly to maintain a wide space
between it and the parts in the engine compartment. If the sensor installed to the back of the
front bumper detects a certain amount of impact by a collision with a pedestrian or other
obstruction while the vehicle is being driven at a speed suf¿ cient to activate the system, the
system is activated and the bonnet is raised.

WARNING
If the active bonnet has activated, always consult an expert repairer, we recommend an
Authorised Mazda Repairer.
If the bonnet release handle is pulled after the active bonnet has activated, the bonnet
will rise even further. If the vehicle is driven with the bonnet raised it will obstruct
visibility and could result in an accident. In addition, do not attempt to push the bonnet
back down. Otherwise, it could deform the bonnet or cause injury because the activated
bonnet cannot be lowered manually. Before driving the vehicle to an expert repairer, we
recommend an Authorised Mazda Repairer after the active bonnet has activated, make
sure that the raised bonnet does not obstruct vision and drive the vehicle at a low speed.

result in a burn as the actuator is hot directly after the activation.
Operation and Handling
 




 Always make sure that the bonnet is closed completely before driving. Otherwise, the
system may not operate normally.
 


 The system may not operate for about 8 seconds after the ignition is switched ON.



 Use tyres of the same speci¿ ed size on all four wheels. If tyres with different sizes are
used, the system may not operate normally.
 


 If something hits the area around the front bumper, the sensor could be damaged even if
the active bonnet does not activate. Always consult an expert repairer, we recommend an
Authorised Mazda Repairer to have the vehicle inspected.
 


 Do not remove or repair parts or wiring for the active bonnet. In addition, do not test
the system’s circuitry using an electric tester. Otherwise, the active bonnet may activate
mistakenly or not operate normally. Consult an expert repairer, we recommend an
Authorised Mazda Repairer for when repairs or replacement servicing is required.
 


 Do not replace the front bumper, bonnet, suspension, aero parts, or wheels with non-
genuine Mazda parts. Otherwise, the system may not operate normally.
 


 Do not install non-genuine Mazda accessories to the front bumper. In addition, do not
install objects on the bonnet. Otherwise, the system may not operate normally.
 


 Do not close the bonnet excessively or apply a load to the actuator. Otherwise, the
actuator could be damaged and cause the system to not operate normally.
 


 Do not modify the suspension. If the vehicle height or the damping force of the
suspensions is changed, the system may not operate normally.
 


 When equipping parts, consult an expert repairer, we recommend an Authorised Mazda
Repairer. If parts are installed incorrectly, the active bonnet may not activate normally due
to the inability to detect an impact.
 


 When disposing of the vehicle, consult an expert repairer, we recommend an Authorised
Mazda Repairer. If the vehicle is not handled correctly, it could result in injury.
 


 The active bonnet cannot be reused if it has been activated. Have the system replaced at
