Ultrasonic Parking Assist
If available, the Ultrasonic Rear Parking Assist (URPA) system assists the driver with parking and avoiding objects while in R (Reverse). URPA operates at speeds less than 8 km/h (5 mph).
The sensors on the rear bumper are used to detect objects up to 2.5m(8 ft) behind the vehicle, and at least 25 cm (10 in) off the ground.
WARNING
The URPA system does not detect pedestrians, bicyclists, animals, or any other objects located below the bumper or that are too close or too far from the vehicle. To prevent injury, death, or vehicle damage, even with URPA, always check behind the vehicle and check all mirrors before backing.
