When the ParkSense Rear Park Assist System is malfunctioning, the instrument cluster will actuate a single chime, once per ignition cycle, and it will display the “CLEAN PARK ASSIST SENSORS” or the “SERVICE PARK ASSIST SYSTEM” message. Refer to “Electronic Vehicle Information Center (EVIC)” in “Understanding Your Instrument Panel” for further information. When the shift lever is moved to REVERSE and the system has detected a faulted condition, the EVIC will display the “CLEAN PARK ASSIST SENSORS” or the “SERVICE PARK ASSIST SYSTEM” message for as long as the vehicle is in REVERSE. Under this condition, ParkSense will not operate.

If “CLEAN PARK ASSIST SENSORS” appears in the Electronic Vehicle Information Center (EVIC) make sure 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 “SERVICE PARK ASSIST SYSTEM” appears in the EVIC, see an authorized dealer.
