Driver Controls • There may be issues with the detection of vehicles in front when driving into and coming out of a bend or curve in the road. In these cases ACC may brake late or unexpectedly. The driver should stay alert and intervene when necessary. If the front end of the vehicle is hit or damaged, the radar sensing zone may be altered causing missed or false vehicle detections. Check with your authorized dealer to have the ACC radar checked for proper coverage and operation. ACC Not Available Several conditions exist which can cause ACC to deactivate or prevent ACC from activating when requested. These conditions include: • The sensor is blocked, refer to Blocked sensor in this section. • Brake temperature is high, refer to Hilly condition usage in this section. • A failure has occurred in the ACC system or related system. 106 2012 Explorer (exp) Owners Guide, 2nd Printing USA (fus)
