Security System
*Some models.
 Theft-Deterrent  System *
              If  the  theft-deterrent  system  detects  an 
inappropriate entry into the vehicle or 
the intrusion sensor detects movement 
in the vehicle which could result in the 
vehicle (with the intrusion sensor) or its 
contents being stolen, the alarm alerts the 
surrounding area of an abnormality by 
sounding the siren/horn and  À ashing the 
hazard warning lights.
  The system will not function unless it's 
properly armed. So when you leave the 
vehicle, follow the arming procedure 
correctly.
  Intrusion  sensor 
*
    The intrusion sensor uses ultrasonic waves 
to detect movement inside the vehicle and 
to raise an alert of an intrusion into the 
vehicle.
  The intrusion sensor detects certain kinds 
of movement inside the vehicle, however, 
it may also respond to phenomenon 
outside the vehicle such as vibrations, loud 
noise, wind, and air currents.
 CAUTION
 In order for the intrusion sensor to 
operate appropriately, be aware of the 
following:
   
      Do not hang clothing or objects from 
a head restraint. 
        Return the sunvisors to their original 
positions.
        Do not blind the intrusion sensor by 
covering it or placing objects over it. 
        Do not allow the intrusion sensor to 
get soiled or wipe it with a liquid. 
        Do not shock or cause an impact to 
the intrusion sensor or the intrusion 
sensor bezel. 
        Do not install seats that are not 
Mazda genuine products. 
        To prevent obstruction of intrusion 
sensor, do not place objects or cargo 
near the intrusion sensor that are 
higher than the head restraints.
