The object detection system will use rear display indicators and the radio speakers for notification. The system can be disabled by pressing the ON/OFF button. The ON/OFF indicator will be ON when the system is OFF. The driver information center (DIC) will also display PARK ASSIST OFF.

CONDITIONS FOR RUNNING THE DTC
Ignition voltage is between 9-16 volts.
