ACC Unavailable Warning

If the system turns off, and the EVIC displays “ACC/ FCW Unavailable, Vehicle System Error”, 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.
