The Lane-Keeping System* is not working on my Ford. What do I do?

Why is the feature not available (lane markings are gray) when I can see the lane markings on the road? 

Possible causes

  • Your vehicle speed is outside the operational range of the feature. 
  • The sun is shining directly into the camera lens. 
  • A quick intentional lane change has occurred. 
  • Your vehicle stays too close to the lane markings. 
  • Driving at high speeds in curves. 
  • The last alert warning or aid intervention occurred a short time ago. 
  • Ambiguous lane markings, for example in construction zones. 
  • Rapid transition from light to dark, or from dark to light. 
  • Sudden offset in lane markings. 
  • Anti-Lock Braking System (ABS) or AdvanceTrac™ is active. 
  • There is a camera blockage due to dirt, grime, fog, frost, or water on the windshield. 
  • You are driving too close to the vehicle in front of you. 
  • Transitioning between no lane markings to lane markings or vice versa. 
  • There is standing water on the road. 
  • Faint lane markings, for example, partial yellow lane markings on concrete roads. 
  • Lane width is too narrow or too wide. 
  • The camera has not been calibrated after a windshield replacement. 
  • Driving on tight roads or uneven roads. 

Why does the vehicle not come back toward the middle of the lane, as expected, in the Aid or Aid + Alert mode? 

Possible causes

  • High crosswinds are present. 
  • There is a large road crown. 
  • Rough roads, grooves, or shoulder drop-offs. 
  • Heavy uneven loading of the vehicle or improper tire inflation pressure. 
  • The tires have been changed, or the suspension has been modified.
