FUNCTION General D A jam protection function automatically stops the power window and moves it downward if a foreign object gets jammed in the door window during one-touch auto-up operation D On the previous model, the jamming of the power window was detected by the limit switch and pulse sensor On the new model, this has been changed to the two hall ICs that are integrated in the all door’s power window motor D The activation of the jam protection function is described below Operation of Jam Protection Function Door Window Position from Full Close 200 mm (7.87 in.) or more Down operation
