ACC Unavailable Warning
If the system turns off, and the EVIC displays “Adaptive Cruise Control (ACC) Unavailable”, there may be a temporary malfunction that limits ACC functionality.
Although the vehicle is still drivable under normal conditions, ACC will be temporarily unavailable. If this occurs, try activating ACC again later, following a key cycle. If the problem persists, see your authorized dealer.
