Ultrasonic Rear Parking Assist (URPA) Your vehicle may be equipped with Ultrasonic Rear Parking Assist (URPA). URPA is designed to help you park while in REVERSE (R) and operates only at speeds less than 3 mph (5 km/h). URPA can help you avoid colliding with objects such as parked vehicles. The system can detect objects 5 feet (1.5 m) behind your vehicle and tell you how close those objects are to your rear bumper. {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. 3-26
