Parking Support Brake (Pedes-
trians Rear of the Vehicle)
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 pedestrian is high, a buzzer
will sound. If the system determines
that the possibility of colliding with the
detected pedestrian is extremely high,
the brakes will be applied automatically
to help reduce the impact of the colli-
sion.
When a pedestrian is detected behind
the vehicle while backing up and the
brake pedal is not depressed or is
depressed late, the PKSB system will
operate automatically.
