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 to repair the system.

PARK ASSIST OFF: If the URPA system does not activate due to a temporary condition, this 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 rear bumper 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.

• An object was hanging out of the trunk during the last drive cycle.

Once the object is removed, URPA will return to normal operation.

• 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.
