Driving and Operating When the System Does Not Seem to Work Properly If the URPA system does not activate due to a temporary condition, the message PARK ASSIST OFF displays on the DIC and a red light comes on the rear URPA display when the shift lever is moved into R (Reverse). This can occur under the following conditions: 8-43 • A tow bar is attached to the vehicle. Fuel Use of the recommended fuel is an important part of the proper maintenance of this vehicle. To help keep the engine clean and maintain optimum vehicle performance, we recommend the use of gasoline advertised as TOP TIER Detergent Gasoline. Look for the TOP TIER label on the fuel pump to ensure gasoline meets enhanced detergency standards developed by auto companies. A list of marketers providing TOP TIER Detergent Gasoline can be found at www.toptiergas.com. • The vehicle's bumper is damaged. Take the vehicle to your dealer/retailer to repair the system. • Other conditions may affect system performance, such as vibrations from a jackhammer or the compression of air brakes on a very large truck that is near the vehicle. If the system is still disabled, after driving forward at least 25 km/h (15 mph), take the vehicle to your dealer/retailer. • The ultrasonic sensors are not clean. Keep the vehicle's rear bumper free of mud, dirt, snow, ice and slush. For cleaning instructions, see Exterior Care on page 9-88. • A trailer was attached to the vehicle, or an object was hanging out of the trunk during the last drive cycle, making the red light come on in the rear display. Once the attached object is removed, URPA will return to normal operation.
