"TECHLINE SUMMARY ARTICLE - IF YOU SEE THE MESSAGE SOME DRIVER ASSIST SYSTEMS CANNOT OPERATE: RADAR OBSTRUCTED IN THE DRIVER INFORMATION INTERFACE, IT MEANS THAT SOMETHING IS BLOCKING OR COVERING THE MILLIMETER WAVE RADAR IN THE FRONT GRILLE, PREVENTING IT FROM DETECTING OBJECTS AHEAD OF THE VEHICLE. YOU MAY ALSO SEE THIS MESSAGE WHEN DRIVING IN RAIN, SNOW, FOG, ETC.
ITÂ’S NOT UNCOMMON FOR IT TO INTERMITTENTLY COME ON WHEN DRIVING UNDER THOSE CONDITIONS."
