If the rear camera sensor detects a pedestrian behind the vehicle while backing up
and the system determines that the possibility of colliding with the detected pedes-
trian is high, a buzzer will sound. If the system determines that the possibility of col-
liding with the detected pedestrian is extremely high, the brakes will be applied
automatically to help reduce the impact of the collision.
When a pedestrian is detected behind the vehicle while backing up, the brake
pedal is not depressed or is depressed late.
