When you are backing the vehicle and objects are detected at the same time near both the front and rear bumpers, both color-coded light displays will notify you of objects close to each bumper. If there are objects detected near both bumpers, the beeps will only be sounded to notify that objects are close to the rear bumper. However, if while you are backing and an object comes within 1 ft (0.3 m) of the front bumper, and at the same time there is another object further than 1 ft (0.3 m) from the rear bumper, then the beeps will only be sounded to notify you of the closer object that is near the front bumper. • A trailer was attached to your vehicle, or a bicycle or an object was hanging out of your trunk during your last drive when you turned off the vehicle. If the attached objects are removed from your vehicle before the start of your next drive, the system will return to normal operation unless an object is detected when the vehicle is shifted out of park. If this occurs, you will have to wait until the vehicle is driven forward above 15 mph (25 km/h) before UFRPA will return to normal operation. • A bicycle or an object is attached to the front bumper during your last drive when you turned off the vehicle. If the attached objects are removed from your vehicle before the start of your next drive, the system will return to normal unless an object is detected when the vehicle is shifted out of park. If this occurs, UFRPA will return to normal operation when the vehicle is driven forward above 15 mph (25 km/h). When the System Does Not Seem to Work Properly If the UFRPA system will not activate due to a temporary condition, the message PARKING ASSIST OFF will be displayed on the DIC and a red light will be shown on the rear UFRPA display when the shift lever is moved into REVERSE (R). This occurs under the following conditions: • The ultrasonic sensors are not kept clean. So be sure to keep your vehicle's front and rear bumpers free of mud, dirt, snow, ice and slush. For cleaning instructions, see Washing Your Vehicle on page 5-86. If after cleaning the front and rear bumpers and driving forward at a speed of at least 15 mph (25 km/h), the DIC displays the PARKING ASSIST OFF message, see your dealer. • The driver disables the system. See DIC Controls and Displays on page 3-72. • The parking brake pedal is depressed. 3-41
