FCW Limited Functionality Warning

~1min read

If the message "ACC/FCW Limited Functionality" or "ACC/FCW Limited Functionality. Clean Windshield" is displayed in the instrument cluster, a condition may temporarily exist that limits FCW functionality. Although the vehicle can still be driven under normal conditions, active braking may not be fully available. Once the condition limiting system performance no longer exists, the system will return to full operation. If the problem is not resolved, see an authorized dealer.
