During vehicle start up, when the ParkSense Rear Park Assist System has detected a faulted condition, the instrument cluster will actuate a single chime, once per ignition cycle, and it will display the "PARKSENSE UNAVAILABLE WIPE REAR SENSORS" or the "PARKSENSE UNAVAILABLE SERVICE REQUIRED" message. Refer to "Electronic Vehicle Information Center (EVIC) or Driver Information Display (DID)" for further information. When the shift lever/gear selector is moved to REVERSE and the system has detected a faulted condition, the EVIC/DID will display the PARKSENSE UNAVAILABLE WIPE REAR SENSORS or PARKSENSE UNAVAILABLE SERVICE REQUIRED message for as long as the vehicle is in REVERSE. Under this condition, ParkSense will not operate.
If "PARKSENSE UNAVAILABLE WIPE REAR SENSORS" appears in the Electronic Vehicle Information Center (EVIC) or Driver Information Display (DID) make sure the outer surface and the underside of the rear fascia/bumper is clean and clear of snow, ice, mud, dirt or other obstruction and then cycle the ignition. If the message continues to appear, see an authorized dealer.
If "PARKSENSE UNAVAILABLE SERVICE REQUIRED" appears in the EVIC/DID, see an authorized dealer.
Cleaning The ParkSense System
Clean the ParkSense sensors with water, car wash soap and a soft cloth. Do not use rough or hard cloths. Do not scratch or poke the sensors. Otherwise, you could damage the sensors.
