With four ultrasonic sensors on the front and rear, available Intuitive Parking Assist detects how close the LS is to surrounding objects. When the Parking Assist button is activated, the system alerts you when another vehicle or object is in close proximity. Distance is indicated by an LCD display, accompanied by an audible beep. The closer the LS is to the object, the more lines appear on the display, and the more frequent the beeping becomes.
