What do I do if the Lane-Keeping System* is not working on my Ford?

The Lane-Keeping System may not engage or your vehicle may not return to the center of the lane. Learn the potential reasons below.

Lane Keeping is Not Engaging

Possible causes are:

Driving Scenarios

  • Your vehicle speed is outside the operational range of the feature. 
  • A quick intentional lane change has occurred. 
  • Driving at high speeds in curves. 
  • You are driving too close to the vehicle in front of you. 

Road Conditions

  • Ambiguous lane markings, for example in construction zones. 
  • Sudden offset in lane markings. 
  • Transitioning between no lane markings to lane markings or vice versa. 
  • Faint lane markings, for example, partial yellow lane markings on concrete roads. 
  • Lane width is too narrow or too wide. 
  • Driving on tight roads or uneven roads. 

Environmental Conditions

  • The sun is shining directly into the camera lens. 
  • Rapid transition from light to dark, or from dark to light.
  • There is standing water on the road.  

Vehicle Symptoms

  • The camera has not been calibrated after a windshield replacement. 
  • There is a camera blockage due to dirt, grime, fog, frost, or water on the windshield. 
  • Anti-Lock Braking System (ABS) or AdvanceTrac™ is active. 
  • Your vehicle stays too close to the lane markings. 
  • The last alert warning or aid intervention occurred a short time ago.

Possible causes are:

  • High crosswinds are present.

  • The tires have been changed, or the suspension has been modified.
