264 Cruise Control Detection Issues The radar sensor has a limited field of vision. It may not detect vehicles at all or detect a vehicle later than expected in some situations. The lead vehicle graphic will not illuminate if the system does not detect a vehicle in front of you. Detection issues can occur: A. When driving on a different line than the vehicle in front. B. With vehicles that edge into your lane. The system can only detect these vehicles once they move fully into your lane. C. 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 the system may brake late or unexpectedly. You should stay alert and intervene when necessary. If the front end of your vehicle is hit or damaged, the radar sensing zone may be altered causing missed or false vehicle detections. See your authorized dealer to have the radar checked for proper coverage and operation. 2013 Explorer (exp) Owners Guide gf, 4th Printing, November 2012 USA (fus)
