Parking Support Brake function (static objects)

If the sensors detect a static object, such as a wall, in the traveling direction of the vehicle and the system determines that a collision may occur due to the vehicle suddenly moving forward due to an accidental accelerator pedal operation, the vehicle moving the unintended direction due to the wrong shift position being selected, or while parking or traveling at low speeds, the system will operate to lessen the impact with the detected static object and reduce the resulting damage.

Examples of function operation

This function will operate in situations such as the following if an object is detected in the traveling direction of the vehicle.

When traveling at a low speed and the brake pedal is not depressed, or is depressed late

When the accelerator pedal is depressed excessively

When the vehicle moves in the unintended direction due to the wrong shift position being selected

Types of sensors

Warning:

To ensure the system can operate properly

Observe the following precautions.

Failing to do so may result in the vehicle being unable to be driven safely and possibly cause an accident.

Do not damage the sensors, and always keep them clean.

Do not attach a sticker or install an electronic component, such as a backlit license plate (especially fluorescent type), fog lights, fender pole or wireless antenna near a radar sensor.

Do not subject the surrounding area of the sensor to a strong impact. If subjected to an impact, have the vehicle inspected by your Toyota dealer. If the front or rear bumper needs to be removed/installed or replaced, contact your Toyota dealer.

Do not modify, disassemble or paint the sensors.

Do not attach a license plate cover.

Keep your tires properly inflated.

Handling the suspension

Do not modify the suspension, as changes to the height or inclination of the vehicle may prevent the sensors from detecting objects correctly or cause the system to not operate or operate unnecessarily.

If the Parking Support Brake function (static objects) operates unnecessarily, such as at a railroad crossing

In the event that the Parking Support Brake function (static objects) operates unnecessarily, such as at a railroad crossing, brake control will be canceled after approximately 2 seconds, allowing you to proceed forward and leave the area, brake control can also be canceled by depressing the brake pedal. Depressing the accelerator pedal after brake control is canceled will allow you to proceed forward and leave the area.

Notes when washing the vehicle

Do not apply intensive bursts of water or steam to the sensor area.

Doing so may result in the sensor malfunctioning.

When using a high pressure washer to wash the vehicle, do not spray the sensors directly, as doing so may cause a sensor to malfunction.

When using steam to clean the vehicle, do not direct steam too close to the sensors as doing so may cause a sensor to malfunction.

Note:

The Parking Support Brake function (static object) will operate when

The function will operate when the PKSB OFF indicator is not illuminated or flashing (Indicators, PKSB OFF indicator (warning buzzer)) and all of the following conditions are met:

Hybrid system output restriction control

The Parking Support Brake is enabled.

The vehicle speed is approximately 9 mph (15 km/h) or less.

There is a static object in the traveling direction of the vehicle and approximately 6 to 13 ft. (2 to 4 m) away.

The Parking Support Brake determines that a stronger-than-normal brake operation is necessary to avoid a collision.

Brake control

Hybrid system output restriction control is operating.

The Parking Support Brake determines that an immediate brake operation is necessary to avoid a collision.

The Parking Support Brake function (static objects) will stop operating when

The function will stop operating if any of the following conditions are met:

Hybrid system output restriction control

The Parking Support Brake is disabled.

The system determines that the collision has become avoidable with normal brake operation.

The static object is no longer approximately 6 to 13 ft. (2 to 4 m) away from the vehicle or in the traveling direction of the vehicle.

Brake control

The Parking Support Brake is disabled.

Approximately 2 seconds have elapsed since the vehicle was stopped by brake control.

The brake pedal is depressed after the vehicle is stopped by brake control.

The static object is no longer approximately 6 to 13 ft. (2 to 4 m) away from the vehicle or in the traveling direction of the vehicle.

Detection range of the Parking Support Brake function (static objects)

The detection range of the Parking Support Brake function (static objects) differs from the detection range of the intuitive parking assist. (Sensor detection display, object distance) Therefore, even if the intuitive parking assist detects an object and provides a warning, the Parking Support Brake function (static objects) may not start operating.

Situations in which the system may not operate properly

Situations in which the system may operate even if there is no possibility of a collision
