When the dynamic radar cruise control system is turned on using the cruise control main switch, the cruise control indicator (vehicle-to-vehicle distance control mode) illuminates. The hybrid vehicle control ECU assembly uses this and other indicators to indicate the control condition (presence or absence of a preceding vehicle, vehicle-to-vehicle distance, and set vehicle speed) and fail-safe state via CAN communication.
