{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. The URPA display is located inside the vehicle, above the liftgate glass. It has three color-coded lights that can be seen through the rearview mirror or by turning around. 3-21
