Ultrasonic Rear Parking Assist (URPA)(Option) Ultrasonic rear parking assist can help you to determine how close an object is to your rear bumper within a given area, making parking easier. The URPA display is located inside the vehicle, above the rear window. It has three color-coded lights that can be seen through the rearview mirror. How the System Works Ultrasonic rear parking assist comes on automatically when the shift lever is moved into REVERSE (R) and the vehicle speed is less than 3 mph (5 km/h). When the system comes on, the three lights on the display will illuminate to let you know that the system is working. URPA senses how close your vehicle is to an object. The distance is determined by the four rear sensors located on the bumper. When shifting into REVERSE (R) and an object is detected, one of the following will occur: A chime will sound the first time an object is detected, if the object is between 20 inches (0.5 m) and 5 feet (1.5 m) away. URPA can detect objects 3 inches (7.6 cm) and wider, and at least 10 inches (2.5 cm) tall, but cannot detect objects that are above trunk level. In order for the rear sensors to recognize an object, it must be within operating range. 2-30
