Enable or disable Pre-Collision System in Toyota Fortuner

The Toyota Fortuner offers a variety of advanced safety features, including a Pre-Collision System (PCS). This system is designed to help prevent accidents by detecting potential collisions and alerting the driver to take action. However, there may be situations where a driver may want to disable the PCS, such as when driving off-road or in certain weather conditions. In this article, we will discuss how to enable or disable the Pre-Collision System in a Toyota Fortuner and some important factors to consider before doing so.

How pre-collision system works in Fortuner

The Pre-Collision System in the Toyota Fortuner is a prime example of how modern technology can improve safety and reduce the risk of accidents. By detecting potential hazards and alerting the driver to take action, this system can help avoid collisions altogether or at least reduce the impact of a collision. The system is especially useful in situations where the driver may not be able to react in time, such as when driving at high speeds or in adverse weather conditions.


Radar sensor and camera

The system is made up of multiple components, including a radar sensor, a front-facing camera, and a control unit that processes information from both sensors. When the system detects an obstacle in front of the vehicle, it calculates the distance, speed, and trajectory of the obstacle to determine the risk of a collision. If the system determines that the risk is high, it will warn the driver with an audible and visual alert to take evasive action.

Automatic braking

If the driver does not take evasive action, the system will automatically apply the brakes to help avoid the collision. This can be especially useful in situations where the driver is distracted or not paying attention to the road ahead. The system is designed to work in conjunction with the driver and not take control of the vehicle entirely. The driver always retains control of the vehicle and can override the system if necessary.

In conclusion, the Pre-Collision System in the Toyota Fortuner is a vital safety feature that can greatly enhance the safety of drivers and passengers on the road. By using advanced technology to detect and avoid potential collisions, the system provides an extra layer of protection and can help prevent accidents before they occur. It is important to remember that this system should not replace good driving habits, such as paying attention to the road and driving defensively.

Disabling pre-collision system in Fortuner

While the Pre-Collision System (PCS) in the Toyota Fortuner is a crucial safety feature, there may be situations where a driver may need to disable it temporarily. For example, when driving on rough terrain, in deep snow or mud, or when the system is detecting obstacles that are not actually a threat.

To disable the PCS in a Toyota Fortuner, follow these steps:

  1. Start your Fortuner.
  2. Using steering wheel controls, go to settings in the instrument cluster display.
  3. Select PCS (Pre-Collision System).
  4. Select PCS On/Off.
  5. Select to enable/disable the pre-collision system.

PCS turns back on automatically on each engine start

In a Toyota Fortuner, the Pre-Collision System (PCS) is automatically enabled each time the engine switch is turned to the “ON” position for vehicles without the smart entry and start system, or the IGNITION ON mode for vehicles with the smart entry and start system.


However, if you choose to disable the system, the PCS warning light will turn on, and a message will be displayed on the multi-information display to inform you that the PCS is currently disabled. It is essential to ensure that the system is functioning correctly at all times to help avoid collisions and reduce the risk of injury or damage.

Changing the pre-collision warning timing

In a Toyota Fortuner, the Pre-Collision System (PCS) offers the option to change the warning timing from Early, Middle to Late. These settings can be easily adjusted via the instrument cluster display settings.

  1. Start your Fortuner.
  2. Using steering wheel controls, go to settings in the instrument cluster display.
  3. Select PCS (Pre-Collision System).
  4. Select Sensitivity (adjust alert timing).
  5. Select to change the pre-collision warning timing.

It is important to note that the warning timing setting will be retained even after turning off the engine. However, if the PCS is disabled and then re-enabled, the operation timing will return to the default setting, which is the Middle timing setting. It is recommended to adjust the warning timing setting based on your driving preferences and conditions to ensure optimal safety on the road.

When to disable the pre-collision system

It is recommended to disable the Pre-Collision System (PCS) in a Toyota Fortuner in certain situations to avoid accidents resulting in death or serious injury. Here are the scenarios when it is recommended to disable the PCS:

  • When the vehicle is being towed.
  • When your vehicle is towing another vehicle.
  • When transporting the vehicle via truck, boat, train or similar means of transportation.
  • When the vehicle is raised on a lift with the engine running and the tires are allowed to rotate freely.
  • When inspecting the vehicle using a drum tester such as a chassis dynamometer or speedometer tester, or when using an on vehicle wheel balancer.
  • When a strong impact is applied to the front bumper or front grille, due to an accident or other reasons.
  • If the vehicle cannot be driven in a stable manner, such as when the vehicle has been in an accident or is malfunctioning.
  • When the vehicle is driven in a sporty manner or off-road.
  • When the tires are not properly inflated.
  • When the tires are very worn.
  • When tires of a size other than specified are installed.
  • When tire chains are installed.
  • When a compact spare tire or an emergency tire puncture repair kit is used.
  • If equipment (snow plow, etc.) that may obstruct the radar sensor or front camera is temporarily installed to the vehicle

It is essential to follow the manufacturer’s guidelines and disable the PCS only when it is necessary and safe to do so. Disabling the system in inappropriate situations could potentially increase the risk of a collision.

PCS safety guidelines

To ensure the safety of yourself and others while operating a vehicle equipped with the Pre-Collision System (PCS), it is important to follow some safety precautions:

  • Always keep the system enabled, except in situations where it is recommended to disable it.
  • Keep the vehicle well-maintained and ensure that all components of the PCS are functioning correctly.
  • Pay attention to the road ahead and keep a safe distance from other vehicles, even when the PCS is enabled.
  • Always wear a seatbelt and ensure that all passengers in the vehicle do the same.
  • Be aware of the PCS warning signals and heed them promptly. If the system warns of an impending collision, take immediate action to avoid the collision.
  • Do not rely solely on the PCS to avoid collisions. Be a defensive driver and always be prepared to take evasive action if necessary.
  • Keep the radar sensor and front camera clean and free of obstructions.
  • Avoid modifying the vehicle or adding equipment that could interfere with the proper functioning of the PCS.
  • If the PCS warning light is on, or if there is any other indication of a problem with the system, have the vehicle inspected by a qualified technician as soon as possible.
  • Familiarize yourself with the owner’s manual and the operation of the PCS to ensure that you are using the system correctly and safely.

In conclusion, the Pre-Collision System (PCS) is an advanced safety feature in Toyota Fortuner that uses radar and camera technology to detect potential collisions and warn the driver or apply brakes automatically to help prevent or reduce the impact of a collision. However, it is important to understand the situations where the system may not work properly and take necessary safety precautions to ensure the system operates effectively. By following the recommended safety precautions and familiarizing yourself with the operation of the PCS, you can help prevent accidents and keep yourself and others safe on the road.
