Head Restraints Seatback Latches CAUTION: If the seatback isn't locked, it could move forward in a sudden stop or crash. That could cause injury to the person sitting there. Always press rearward on the seatback to be sure it is locked. Slide the head restraint up or down so that the top of the restraint is closest to the top of your ears. This position reduces the chance of a neck injury in a crash. The front seatback folds forward to let people get into the rear seat. The seatback will move back and forth freely unless you come to a sudden stop, then it will lock into place. 1-6
