Lexus ES: PKSA (Parking Support Alert)
The Parking Support Alert system 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, such as a wall, or pedestrian is high, a warning operates to urge the driver to take evasive action.
