Cruise Main Indicator Light Circuit [04/2018 - 08/2021]: Description
WARNING: This page is about a different variant/trim than selected.
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 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.
