If the following conditions are detected while the dynamic radar cruise control system is operating, the system clears the stored vehicle speed in the ECM and cancels the dynamic radar cruise control operation.
HINT:
During constant speed control mode, the cruise main indicator light (constant speed control mode) flashes. During vehicle-to-vehicle distance control, the cruise main indicator light (vehicle-to-vehicle distance control mode) flashes.
