Ultrasonic Rear Parking Assist (URPA) 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, on the center console. It has three color-coded lights that can be seen through the rearview mirror or by turning around. {CAUTION: Even with the Ultrasonic Rear Park Assist system, the driver must check carefully before backing up. The system does not operate above typical backing speeds of 3 mph (5 km/h) while parking. And, the system does not detect objects that are more than 5 feet (1.5 meters) behind the vehicle. So, unless you check carefully behind you before and when you back up, you could strike children, pedestrians, bicyclists or pets behind you, and they could be injured or killed. Whether or not you are using rear park assist, always check carefully behind your vehicle before you back up and then watch closely as you do. How the System Works URPA 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 ultrasonic sensors located on the rear bumper. 3-38
