Toyota Corolla Cross: PKSB (Parking Support Brake)

The PKSB (Parking Support Brake) consists of the following functions that operate when driving at a low speed or backing up, such as when parking. When the system determines that the possibility of a collision with a detected object is high, a warning operates to urge the driver to take evasive action. If the system determines that the possibility of a collision with a detected object is extremely high, the brakes are automatically applied to help avoid the collision or help reduce the impact of the collision.

PKSB (Parking Support Brake) system

The system can detect the following as detectable objects.

(Detectable objects differ depending on the function.)

  • Static Objects Front and Rear of the vehicle
  • Moving Vehicles Rear of the Vehicle

WARNING

■Cautions regarding the use of the system

Do not overly rely on the system, as doing so may lead to an accident.

Always drive while checking the safety of the surroundings of the vehicle.

Depending on the vehicle and road conditions, weather, etc., the system may not operate.

The detection capabilities of sensors and radars are limited.

Always drive while checking the safety of the surroundings of the vehicle.

  • The driver is solely responsible for safe driving. Always drive carefully, taking care to observe your surroundings. The PKSB (Parking Support Brake) system is designed to provide support to lessen the severity of collisions.

    However, it may not operate in some situations.

  • The PKSB (Parking Support Brake) system is not designed to stop the vehicle completely.

    Additionally, even if the system has stopped the vehicle, it is necessary to depress the brake pedal immediately as brake control will be canceled after approximately 2 seconds.

  • It is extremely dangerous to check the system operations by intentionally driving the vehicle into the direction of a wall, etc. Never attempt such actions.

■When to disable the PKSB (Parking Support Brake) system

In the following situations, disable the PKSB (Parking Support Brake) as the system may operate even though there is no possibility of a collision.

  • When inspecting the vehicle using a chassis roller, chassis dynamo or free roller
  • When loading the vehicle onto a boat, truck or other transport vessel
  • If the suspension has been modified or tires of a size other than specified are installed
  • If the front of the vehicle is raised or lowered due to the carried load
  • When equipment that may obstruct a sensor is installed, such as a towing eyelet, bumper protector (an additional trim strip, etc.), bicycle carrier, or snow plow
  • When using automatic car washing devices
  • 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 a tire chains or compact spare tire is used
  • When your vehicle is towing a trailer or during emergency towing

■Precautions for the suspension

Do not modify the suspension of the vehicle. If the height or tilt of the vehicle is changed, the sensors may not be able to detect detectable objects and the system may not operate correctly, possibly leading to an accident.

Enabling/Disabling the PKSB (Parking Support Brake)

The PKSB (Parking Support Brake) system can be enabled/disabled on of the multi-information display.

When the PKSB (Parking Support Brake) function is off, the driving assist information indicator will illuminate.

When turned OFF (disabled), the PKSB (Parking Support Brake) will be disabled and will not be enabled until the setting is changed to ON again in multi-information display.

(The function will not be reenabled by operating the engine switch.)

Displays and buzzers for engine output restriction control and brake control

If the engine output restriction control or brake control operates, a buzzer will sound and a message will be displayed on the multi-information display, to alert the driver.

Depending on the situation, engine output restriction control will operate to either limit acceleration or restrict output as much as possible.

  • Engine output restriction control is operating (acceleration restriction)

Acceleration greater than a certain amount is restricted by the system.

Multi-information display: "Object Detected Acceleration Reduced"

Driving assist information indicator: Not illuminated

Buzzer: Does not sound

  • Engine output restriction control is operating (output restricted as much as possible)

The system has determined that stronger-than-normal brake operation is necessary.

Multi-information display: "BRAKE!" Driving assist information indicator: Not illuminated

Buzzer: Short beep

  • Brake control is operating

The system determined that emergency braking is necessary.

Multi-information display: "BRAKE!"

Driving assist information indicator: Not illuminated

Buzzer: Short beep

  • Vehicle stopped by system operation

The vehicle has been stopped by brake control operation.

Multi-information display: "Switch to Brake" (If the accelerator pedal is not depressed, "Press Brake Pedal" will be displayed.)

Driving assist information indicator: Illuminated

Buzzer: Sounds repeatedly
