9. Check Jam Protection: Notes

HINT:Β 

The jam protection function prevents any part of your body from getting caught by accident between the door frame and the door glass during power window operation.

  1. Check that the door glass goes down by approximately 50 mm (2.0 in.) right when something gets caught between the door frame and the door glass during power window operation. However, when the opening between the door frame and the door glass is less than 200 mm (7.9 in.), the door glass keeps going down until the opening reaches 200 mm (7.9 in.) and stops there.
