The following messages may be displayed on the DIC:

SERVICE PARKING ASSIST:

If this message occurs, take the vehicle to your dealer to repair the system.

PARK ASSIST OFF: If the UFRPA system does not activate due to a temporary condition, the message displays on the DIC. This can occur under the following conditions:

- The driver has disabled the system.

- The ultrasonic sensors are not clean. Keep the vehicle's bumpers free of mud, dirt, snow, ice and slush. For cleaning instructions, see Exterior Care .

- The park assist sensors are covered by frost or ice. Frost or ice can form around and behind the sensors and may not always be seen; this can occur after washing the vehicle in cold weather. The message may not clear until the frost or ice has melted.

- A trailer was attached to the vehicle, or an object was hanging out of the liftgate during the last drive cycle. Once the attached object is removed, UFRPA will return to normal operation.

- An object or cover is attached to the front of the vehicle.

- A tow bar is attached to the vehicle.

- The bumper is damaged.

Take the vehicle to your dealer to repair the system.

- Other conditions, such as vibrations from a jackhammer or the compression of air brakes on a very large truck, are affecting system performance.
