Toyota bZ4X Owner's Manual: Parking Support Brake Function: Detecting Moving Vehicles Approaching from the Rear of Your Vehicle

The Parking Support Brake system in your 2025 Toyota bZ4X is equipped with rear radar sensors designed to detect vehicles approaching from either the right or left while you are reversing. If the system determines that there is a high likelihood of a collision, it will automatically engage the brake control to help reduce the severity of a potential impact with the approaching vehicle.

This specific function of the Parking Support Brake system will activate in situations such as the following if an approaching vehicle is detected while you are reversing:

When reversing and a vehicle is approaching from the side or rear, and the brake pedal is not depressed, or is depressed with insufficient force or delay.

WARNING

To ensure the system can operate properly

The Parking Support Brake function for detecting moving vehicles approaching from the right or left at the rear of your 2025 Toyota bZ4X will operate when the driving assist information indicator is not illuminated, and all of the following conditions are met:

• EV System Output Restriction Control
  • The Parking Support Brake system is enabled through the vehicle's settings.
  • The vehicle's speed is approximately 9 mph (15 km/h) or less, typical for parking maneuvers.
  • Vehicles are approaching from the right or left at the rear of your vehicle at a traveling speed of approximately 5 mph (8 km/h) or more.
  • The gear shift is in the 'R' (Reverse) position.
  • The Parking Support Brake system assesses that a stronger-than-normal brake operation is necessary to prevent a potential collision with the approaching vehicle.
• Brake Control
  • The EV system output restriction control is already active, limiting the vehicle's power output.
  • The Parking Support Brake system determines that an immediate and forceful emergency brake operation is required to avoid an imminent collision with a vehicle approaching from the rear.

The Parking Support Brake function for detecting moving vehicles from the rear will stop operating if any of the following conditions occur:

• EV System Output Restriction Control
  • The Parking Support Brake system is disabled.
  • The system determines that a collision has become avoidable with normal driver brake operation.
  • A vehicle is no longer detected approaching from the right or left at the rear of your vehicle.
• Brake Control
  • The Parking Support Brake system is disabled.
  • Approximately 2 seconds have elapsed since the vehicle was brought to a stop by the system's brake control.
  • The driver manually depresses the brake pedal after the vehicle has been stopped by the automatic brake control.

The Parking Support Brake function for moving vehicles approaching from the rear may have limitations in certain situations. Please consult your 2025 Toyota bZ4X owner's manual for specific details.

Under certain conditions, the Parking Support Brake function for moving vehicles approaching from the rear might issue alerts or activate braking even without an imminent collision risk. Refer to your vehicle's manual for more information.

If the rear camera sensor of your 2025 Toyota bZ4X detects a pedestrian located behind the vehicle while you are backing up, and the system assesses a high probability of a collision, an audible buzzer will sound to alert you. Furthermore, if the system determines that the risk of collision with the detected pedestrian is extremely high, it will automatically apply the brakes to help minimize the impact of the collision.

Examples of system operation

The system operates when an approaching pedestrian is detected behind the vehicle while backing up, and when the brake pedal is not depressed or is depressed late

WARNING

What to Do If the Parking Support Brake Function (Pedestrians Rear of the Vehicle) Activates Unnecessarily

If the Parking Support Brake function for pedestrians behind your 2025 Toyota bZ4X engages unexpectedly, immediately depress the brake pedal. This action will override and cancel the system's operation, allowing you to regain direct control of the vehicle.

• Proper Use of the Parking Support Brake Function (Pedestrians Rear of the Vehicle)

The Parking Support Brake function for detecting pedestrians behind your vehicle will operate when the driving assist information indicator on your dashboard is not illuminated, and all of the following conditions are met:

• EV System Output Restriction Control
  • The Parking Support Brake system is enabled and active.
  • The vehicle's speed is 9 mph (15 km/h) or less, indicating a slow backing-up scenario.
  • The gear shift is in the 'R' (Reverse) position.
  • A pedestrian is detected in the area directly behind your vehicle by the rear camera sensor.
  • The PKSB system assesses that a stronger-than-normal brake operation is necessary to avoid a potential collision with the detected pedestrian.
• Brake Control
  • The EV system output restriction control is already active, limiting the vehicle's power.
  • The Parking Support Brake system determines that an immediate and forceful emergency brake operation is required to prevent an imminent collision with the pedestrian behind your 2025 Toyota bZ4X.

The Parking Support Brake function for detecting pedestrians will cease operation if any of the following conditions occur:

• EV System Output Restriction Control
  • The Parking Support Brake system is disabled.
  • The system determines that a collision has become avoidable with normal driver brake operation.
  • The pedestrian is no longer detected behind your vehicle by the rear camera.
• Brake Control
  • The Parking Support Brake system is disabled.
  • Approximately 2 seconds have elapsed since the vehicle was brought to a stop by the system's brake control.
  • The driver manually depresses the brake pedal after the vehicle has been stopped by the automatic brake control.

To re-enable this specific function of the Parking Support Brake system after it has been triggered, you can either re-enable the entire PKSB system through the vehicle's settings or turn the power switch off and then back on.

It's important to understand that the detection area of the Parking Support Brake function for pedestrians behind your 2025 Toyota bZ4X might differ from the detection area of the Rear Camera Detection (RCD) function. Therefore, even if the RCD system detects a pedestrian and provides a visual or audible alert, the Parking Support Brake function for pedestrians might not necessarily initiate automatic braking.

The Parking Support Brake function for detecting pedestrians behind your vehicle might have limitations under certain circumstances. Please refer to your 2025 Toyota bZ4X owner's manual for a detailed list of these situations.

Under specific conditions, the Parking Support Brake function for pedestrians behind your vehicle could potentially issue warnings or activate braking even if no pedestrian is actually present. For a comprehensive understanding of these scenarios, please consult your vehicle's owner's manual.

The pedestrian detection feature of the Parking Support Brake in your 2025 Toyota bZ4X provides an added layer of security when reversing, further enhancing parking safety.
