When you first start the vehicle the display will show BUICK and the Buick logo for a few seconds. If it is cold outside, this display may stay on for up to a minute. Clean the inside of the windshield as needed to remove any dirt or film that reduces the sharpness or clarity of the HUD image. To clean the HUD, spray household glass cleaner on a soft, clean cloth. Wipe the HUD lens gently, then dry it. Do not spray cleaner directly on the lens because the cleaner could leak into the unit. If the ignition is on and you cannot see the HUD image, check to see if one of the following conditions exist: Ultrasonic Rear Parking Assist (URPA) The Ultrasonic Rear Parking Assist (URPA) system is designed to help you park, while the vehicle is in REVERSE (R). It operates only at very low speeds, less than 3 mph (5 km/h). URPA can help make parking easier and to help you avoid colliding with objects such as parked vehicles. The URPA system can detect objects up to 5 feet (1.5 m) behind the vehicle, and tell you how close these objects are from your rear bumper. Your vehicle's URPA operates when the shift lever is moved into REVERSE (R) and the vehicle speed is less than 3 mph (5 km/h). Four ultrasonic sensors located at the rear bumper are used to detect the distance to the object. The URPA display is located inside the vehicle, near the rear window. It has three color-coded lights used to provide distance and system information to the driver.
