Parking Support Brake function (rear-crossing vehicles)^{* *}If equipped If a rear radar sensor detects a vehicle approaching from the right or left at the rear of the vehicle and the system determines that the possibility of a collision is high, this function will perform brake control to reduce the likelihood of an impact with the approaching vehicle. Examples of function operation This function will operate in situations such as the following if a vehicle is detected in the traveling direction of the vehicle. When reversing, a vehicle is approaching and the brake pedal is not depressed, or is depressed late Types of sensors BSM (Blind Spot Monitor)* Warning: To ensure the system can operate properly Observe the following precautions regarding the rear radar sensors (To ensure the system can operate properly). Failure to do so may cause a sensor to not operate properly, and may cause an accident. Do not modify, disassemble or paint the sensors. Do not replace a rear radar sensor with a part other than a genuine part. Do not damage the rear radar sensors, and always keep the radar sensors and their surrounding area on the bumper clean. If the area around a rear radar sensor is subjected to an impact, the system may not operate properly due to a sensor malfunction. Have the vehicle inspected by your Toyota dealer. Observe the rear radar sensor handling precautions. (To ensure the system can operate properly) Note: The Parking Support Brake function (rear-crossing vehicles) 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: Engine output restriction control The Parking Support Brake is enabled. The vehicle speed is approximately 9 mph (15 km/h) or less. Vehicles are approaching from the right or left at the rear of the vehicle at a traveling speed of approximately 5 mph (8 km/h) or more. The shift position is in R. The Parking Support Brake determines that a stronger than normal brake operation is necessary to avoid a collision with an approaching vehicle. Brake control Engine output restriction control is operating. The Parking Support Brake determines that an emergency brake operation is necessary to avoid a collision with an approaching vehicle. The Parking Support Brake function (rear-crossing vehicles) will stop operating when The function will stop operating if any of the following conditions are met: Engine output restriction control The Parking Support Brake is disabled. The collision becomes avoidable with normal brake operation. A vehicle is no longer approaching from the right or left at the rear 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. A vehicle is no longer approaching from the right or left at the rear of the vehicle. Detection area of the Parking Support Brake function (rear-crossing vehicles) The detection area of the Parking Support Brake function (rear-crossing vehicles) differs from the detection area of the RCTA function (RCTA function detection areas). Therefore, even if the RCTA function detects a vehicle and provides an alert, the Parking Support Brake function (rear-crossing vehicles) may not start operating. Situations in which the system may not operate properly 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 Situations in which the system may operate even if there is no possibility of a collision
