The 2025 4Runner integrates advanced safety technologies such as Parking Support Brake (PKSB) and Rear Camera Detection (RCD) to enhance the driving and parking experience. These features work together to provide both proactive and reactive assistance when parking and maneuvering in tight spaces, aiming to minimize potential collisions.

Parking Support Brake (PKSB)​

The Parking Support Brake (PKSB) is a vital safety system designed to prevent accidents while parking or reversing by automatically applying the brakes when an obstacle is detected in the vehicle's path.

• System Functionality: PKSB uses radar and sensors to continuously monitor the area around the vehicle, detecting obstacles such as walls, posts, or other vehicles. When reversing or moving forward at low speeds, if an obstacle is detected in the vehicle’s path, PKSB can automatically apply the brakes to avoid a collision.
• Activation: PKSB is automatically engaged when the vehicle is in reverse (R) or forward at low speeds (e.g., during parking maneuvers). The system’s sensors constantly monitor the area for any obstructions, triggering braking if an obstacle is detected.
• Limitations: While PKSB is an advanced safety feature, it is important to note that the system may have limited effectiveness in detecting smaller objects, objects with irregular shapes, or obstacles that are very close to the vehicle. Additionally, PKSB may not be as effective in low-light conditions or adverse weather, which can obscure sensor readings.
• Warning: If PKSB is engaged and the system applies the brakes, a warning light will illuminate on the dashboard to inform the driver that the system has intervened.

Rear Camera Detection (RCD)​

The Rear Camera Detection (RCD) system in the 2025 4Runner enhances visibility when reversing by utilizing a rear-facing camera to provide a real-time video feed of the area behind the vehicle, displayed on the infotainment screen.

• Detection Functionality: The RCD system works in conjunction with the vehicle’s backup camera to detect objects behind the vehicle as it moves in reverse. It provides visual alerts on the screen when objects are detected in the vehicle's path.
• Alerts: In addition to the visual display, RCD can also provide audible alerts if an obstacle is detected while reversing. These warnings increase in frequency and intensity as the vehicle gets closer to the obstruction.
• Camera Features: The system typically includes dynamic guidelines that adjust based on the vehicle’s steering angle, providing enhanced situational awareness. This feature is particularly useful when navigating tight spaces or parking in crowded environments.
• Limitations: RCD is highly effective in detecting large, easily visible objects but may struggle to detect low or small objects, such as curbs or small debris, which may be outside the camera’s range or field of view. The system is also reliant on the camera’s visibility, so dirty or obstructed lenses can reduce its effectiveness.

How to Use Parking Support Brake (PKSB) & Rear Camera Detection (RCD)​

1. Activating the Systems: Both PKSB and RCD are automatically activated when the vehicle is in reverse (R) or moving at low speeds in forward gear. However, the systems can be manually enabled or disabled through the vehicle's settings menu if preferred.
2. Adjusting Settings: The sensitivity and operation of RCD and PKSB can be adjusted via the vehicle's multi-information display. It is recommended to periodically check the system’s settings to ensure it’s tailored to your driving conditions.
3. Disabling the Systems: If desired, the Parking Support Brake (PKSB) and Rear Camera Detection (RCD) systems can be deactivated through the vehicle’s customization settings. However, it’s generally advisable to keep these systems enabled for enhanced safety, especially in parking scenarios.

How To disable the Parking Support Brake (PKSB) and Rear Camera Detection (RCD) on 6th Gen 4Runner​

Disabling Parking Support Brake (PKSB):

The PKSB system can be turned off through the vehicle’s customization settings:

1. Go to the Settings menu in the vehicle’s multi-information display.
2. Find the option for Parking Support Brake and toggle it to Off.
3. The system will no longer automatically intervene when an obstacle is detected while parking or reversing.

Disabling Rear Camera Detection (RCD):

To disable the Rear Camera Detection system, follow these steps:

1. Access the Settings menu on the infotainment screen.
2. Navigate to Rear Camera Settings.
3. Toggle the Rear Camera Detection feature to Off. This will stop the visual and audible alerts when reversing.

Note: While it is possible to disable these features, it is generally recommended to keep them active for enhanced safety when parking or reversing. Disabling them could reduce the effectiveness of collision avoidance systems in certain situations.
