Parking Assist
WARNING: This page is about a different car, the 2012 Chevrolet Cruze. However, it is still accessible from the selected car via links, so may be relevant.
The ultrasonic parking assist system is designed to identify and notify the driver of an object in the vehicle's path when reversing at speeds of less than 8 km/h (5 MPH). The distance and location of the object is determined by 4 object sensors located in the rear bumper. The parking assist system will notify the driver using an audible beep signal through the radio.
