How anti-theft alarm system works in Toyota Fortuner

One of the features that make Toyota Fortuner stand out from its competitors is its anti-theft alarm system. This system is designed to protect the vehicle from theft and unauthorized entry. In this article, we will explore how the anti-theft alarm system works in the Toyota Fortuner and what measures are in place to prevent theft.

The anti-theft alarm system in Fortuner is designed to detect unauthorized entry and alert the owner with both sound and light. When an intrusion is detected, the system triggers the horn and flashes the lights to draw attention to the vehicle. This helps to deter potential thieves and notify people nearby of a possible theft.

What triggers the alarm

The alarm is triggered in the following situations when the alarm is set:

  • A locked door is opened in any way other than using the entry function (vehicles with smart entry & start system), wireless remote control or mechanical key.
  • The hood is opened.
  • The intrusion sensor detects something moving inside the vehicle. (An intruder gets in the vehicle.) (if equipped)
  • The quarter windows or back door window are broken. (if equipped)
  • A person inside the vehicle opens a door or hood.
  • Vehicles with power siren: The battery is disconnected.

Setting the alarm system

To prevent unexpected triggering of the alarm and vehicle theft, make sure of the following:

  • Nobody is in the vehicle.
  • The windows are closed before the alarm is set.
  • No valuables or other personal items are left in the vehicle

To set the anti-theft alarm system in the Toyota Fortuner, you must first ensure that all doors and the hood are closed. Next, you can lock all the doors using either the entry function, which is available on vehicles with the smart entry and start system, or the wireless remote control. Once all the doors are locked, the system will be set automatically after a period of 30 seconds.

During this time, you should be able to see a small red indicator light on the dashboard, which confirms that the system is armed and ready to detect any potential intrusions or tampering. It’s important to remember that once the system is set, any attempt to open the doors or tamper with the vehicle’s ignition system will trigger the alarm and alert the owner.

Deactivating or stopping the alarm

Do one of the following to deactivate or stop the alarms:

  • Unlock the doors using the entry function (vehicles with smart entry & start system) or the wireless remote control.
  • Start the engine. (The alarm will be deactivated or stopped after a few seconds.)

Intrusion sensor

In addition to the standard anti-theft alarm system, some Toyota Fortuner models may also come equipped with an intrusion sensor. This sensor is designed to detect any intruders or movements inside the vehicle, and if triggered, will activate the alarm system.

The intrusion sensor can be especially useful in detecting attempts to break into the vehicle through the windows, as well as movements inside the vehicle itself. This provides an added layer of security, making it more difficult for thieves to gain access to the vehicle and potentially steal it.

It’s important to note, however, that while the intrusion sensor can be an effective deterrent against theft, it does not guarantee absolute security against all intrusions. There are still ways in which a determined thief may be able to bypass or disable the sensor, and it is ultimately up to the owner to take additional precautions to ensure the safety and security of their vehicle.

Overall, the intrusion sensor is a valuable addition to the Toyota Fortuner’s anti-theft system, providing an extra layer of protection against potential intruders and making the vehicle more secure for its owners.

The intrusion sensor will be set automatically when the alarm is set.

How to disable the intrusion sensor

If you plan on leaving pets or other moving items inside your Toyota Fortuner while the anti-theft alarm system is set, it is important to stop the intrusion sensor before the alarm is set. This is because the intrusion sensor is designed to detect any movement or intruders inside the vehicle, and it may trigger the alarm if it senses any movement.

  1. Turn the engine switch to the “LOCK” position (vehicles without smart entry & start system) or off (vehicles with smart entry & start system).
  2. Press the intrusion sensor cancel switch. When the system is canceled, the indicator flashes rapidly.

It’s important to note that leaving pets or other living beings inside a vehicle for extended periods of time can be dangerous, especially in hot weather. Always make sure to take appropriate precautions and never leave pets or children unattended in a vehicle for extended periods of time, even with the intrusion sensor disabled.

Canceling and automatic re-enabling of the intrusion sensor (if equipped)

  • The alarm will still be set even when the intrusion sensor is canceled.
  • Vehicles without smart entry & start system: After the intrusion sensor is canceled, turning the engine switch to the “ON” position or unlocking the doors using the wireless remote control will re-enable the intrusion sensor.
  • Vehicles with smart entry & start system: After the intrusion sensor is canceled, pressing the engine switch or unlocking the doors using the entry function or wireless remote control will re-enable the intrusion sensor.
  • The intrusion sensor will automatically be re-enabled when the alarm system is deactivated.

Intrusion sensor detection considerations

The sensor may trigger the alarm in the following situations:

  • A window is open. In this case, the sensor may detect the following: Wind or the movement of objects such as leaves and insects inside the vehicle. Ultrasonic waves emitted from devices such as the intrusion sensors of other vehicles. The movement of people outside the vehicle.
  • Small insects such as moths or flies are in the vehicle.
  • Unstable items, such as dangling accessories or clothes hanging on the coat hooks, are in the vehicle.
  • Places with extreme vibrations or noises, or situations in which the vehicle is subject to repeated impacts or vibrations:
    • When parked in a parking garage.
    • When the vehicle is transported by a ferry, trailer, train, etc.
    • When ice adhering to the vehicle is removed.
    • When the vehicle is in an automatic or high-pressure car wash.
    • When in a hail or lightning storm.

In conclusion, the anti-theft alarm system in the Toyota Fortuner is a valuable security feature that is designed to prevent and deter theft of the vehicle. The system uses a combination of sound and light to alert the owner of any potential intrusions, and can also include an intrusion sensor that detects movement inside the vehicle.

However, it is important to remember that the system is not foolproof and additional precautions may need to be taken to ensure the safety and security of the vehicle.
