The Precision Park 4000 is a reverse park assist system utilizing ultrasonic technology to detect obstacles behind the vehicle when backing. The system engages when the vehicle is shifted into reverse. Four nickel-sized sensors mounted into the rear bumper emit an ultra high frequency (ultra sonic) sound wave that is reflected back from an obstacle. When an obstacle is detected, the system alerts the driver with an audible beep that quickens as the obstacle nears and via the LED display that shows distance and location to obstacle. A feature packed no compromise reverse parking aid.

“With Preceision Park, I feel much more confident when reversing; it’s like having eyes in the back of my car. Thank you for a great product.”
