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:

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:

WARNING
  Luggage or other items placed under the passenger seat or between the passenger
seat and driver seat that push up the passenger seat bottom.
  An object, such as a seat cushion, is put on the passenger's seat or between the
passenger's back and the seatback.
  A seat cover is put on the passenger's seat. 
 Luggage or other items are placed on the seat with the child in the child-restraint
system.
  The seat is washed. 
 Liquids are spilled on the seat. 
 The passenger seat is moved backward, pushing into luggage or other items placed
behind it.
  Luggage or other items are placed between the passenger seat and driver seat. 
 An electric device is put on the passenger's seat. 
 An additional electrical device, such as a seat warmer is installed to the surface of
the passenger seat.
The passenger front and side air bags and seat belt pretensioner systems will deactivate
if the passenger air bag deactivation OFF indicator light turns on.
CAUTION
  To assure proper deployment of the front air bag and to prevent damage to the sensor
in the seat cushion:
 


 Do not place sharp objects on the seat cushion or leave heavy luggage on them.



 Do not spill any liquids on the seats or under the seats.


 To allow the sensors to function properly, always perform the following:




 Adjust the seats as far back as possible and always sit upright against the seatbacks
with seat belts worn properly.
 


 If you place your child on the passenger seat, secure the child-restraint system
properly and slide the passenger seat as far back as possible within the position in
which the child-restraint system can be installed.

NOTE
  The system requires about 10 seconds to alternate between turning the passenger front
and side air bags and seat belt pretensioner system on or off.
  The passenger air bag deactivation OFF indicator light may turn on repeatedly if
luggage or other items are put on the passenger seat, or if the temperature of the
vehicle's interior changes suddenly.
  The passenger air bag deactivation OFF indicator light may turn on for 10 seconds if
the electrostatic capacity on the passenger seat changes.
  The air bag/seat belt pretensioner system warning light might turn on if the passenger
seat receives a severe impact.
  If the passenger air bag deactivation OFF indicator light does not turn on after
installing a child-restraint system on the passenger seat, ¿ rst, re-install your child-
restraint system according to the procedure in this owner's manual. Then, if the
passenger air bag deactivation OFF indicator light still does not turn on, and consult an
Authorised Mazda Repairer as soon as possible.
  If the passenger air bag deactivation OFF indicator light turns on when an occupant
is seated directly in the passenger seat, have the passenger re-adjust their posture by
sitting with their feet on the À oor, and then re-fastening the seat belt. If the passenger
air bag deactivation OFF indicator light remains turned on, slide the passenger seat as
far back as possible. Consult an Authorised Mazda Repairer as soon as possible.

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.
