OCCUPANT RESTRAINT SYSTEMS G16250 G16130 To adjust the height of the head restraint manually, adjust it while pushing the button located on the shoulder. After adjusting the head restraint manually, even if you adjust the seat to the foremost (or rearmost) position using seat position control, the head restraint may not be adjusted to the lowest (or highest) position. And if the head restraint reaches the highest (or lowest) position while the seat is being adjusted backward (or forward), the head restraint will be fixed in that position. To move the head restraint forward or rearward, move the head restraint as shown. The head restraint is most effective when it is close to your head. Therefore, using a cushion on the seatback is not recommended. CAUTION Adjust the center of the head restraint so that it is closest to the top of your ears. 145
