Ultrasonic Parking Assist
If available, the Ultrasonic Rear Parking Assist (URPA) system uses sensors on the rear bumper to assist with parking and avoiding objects while in R (Reverse). It operates at speeds less than 8 km/h (5 mph). URPA uses audible beeps to provide distance and system information.
Keep the sensors on the vehicle's rear bumper clean to ensure proper operation.
