9-38 Driving and Operating How the System Works URPA comes on automatically when the shift lever is moved into R (Reverse). A single beep sounds to indicate the system is working. URPA operates only at speeds less than 8 km/h (5 mph). An obstacle detection is indicated by beeps. The time between beeps gets shorter as the vehicle approaches the obstacle. Repeated beeps are heard when the distance is less than 30 cm (12 in). To be detected, objects must be at least 25 cm (10 in) off the ground and below rear door level. Objects must also be within 2.5 m (8 ft) from the rear bumper. This distance may be less during warmer or humid weather. Driver Assistance Systems 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). Turning the System On and Off The system can be disabled through the Driver Information Center (DIC). See "Park Assist" under Driver Information Center (DIC) on page 5-25. URPA defaults to the on setting each time the vehicle is started. Turn URPA off when towing a trailer. { Warning The URPA system does not detect children, pedestrians, bicyclists, animals, or objects below the bumper or that are too close or too far from the vehicle. It is not available at speeds greater than 8 km/h (5 mph). To prevent injury, death, or vehicle damage, even with URPA, always check the area around the vehicle and check all mirrors before backing. When the System Does Not Seem to Work Properly The following messages may be displayed on the DIC: SERVICE PARK ASSIST: If this message occurs, take the vehicle to your dealer for repair. PARK ASSIST OFF: This message occurs if the driver disables the system or if the vehicle is driven above 8 km/h (5 mph) in R (Reverse).
