SYSTEM DESCRIPTION

OUTLINE OF THEFT DETERRENT SYSTEM

  • The theft deterrent system can be set/canceled by locking/unlocking the doors using any of the following operations:
    • Entry lock/unlock operation
    • Wireless lock/unlock operation*1
    • Key linked lock/unlock operation
    • Opening and closing the doors*2
      • *1: Using the remote door lock and unlock is also considered to be a wireless lock/unlock operation. (for Toyota Entune Remote Connect Compatible Type)
      • *2: Only when setting the theft deterrent system.
  • The alarm function will be activated when someone attempts to forcibly unlock any of the doors or open any of the doors or the engine hood while the system is in the armed state.
  • In the alarm sounding state, the system illuminates the interior lights and blinks the turn signal lights and the exterior lights. At the same time, the system sounds the vehicle horn and security horn assembly to deter break-in and theft as well as to warn people around the vehicle.

    HINT:

    The interior lights are illuminated if the interior light door switches in the map light assembly and no. 1 room light assembly are on.

  • The theft deterrent system has an active arming mode. There are 4 states in this mode; a disarmed state, an arming preparation state, an armed state and an alarm sounding state.

(a) Disarmed state:

  • The alarm function is not operating.
  • The theft deterrent system is not operating.
