194 UNDERSTANDING THE FEATURES OF YOUR VEHICLE • FCW will not react to irrelevant objects such as overhead objects, ground reflections, objects not in the path of the car, stationary objects that are far away, oncoming traffic, or leading vehicles with the same or higher rate of speed. • FCW will be disabled like ACC below with the unavailable screens. FCW 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 FCW functionality. Although the vehicle is still drivable under normal conditions, FCW will be temporarily unavailable. If this occurs, try activating FCW again later, following a key cycle. If the problem persists, see your authorized dealer. Service FCW Warning If the system turns off, and the EVIC displays "ACC/ FCW Unavailable Service Radar Sensor", it indicates there is an internal system fault. Although the vehicle is still drivable under normal conditions, have the system checked by an authorized dealer. ACC/FCW Unavailable Warning
