FEATURES OF YOUR HYUNDAI 1 21 B110A01NF-GAT ! FOLDING REAR SEATBACKS WARNING: ! WARNING: B110A01NF B080D02TG-1 o For maximum effectiveness in case of an accident, the headrest should be adjusted so the middle of the headrest is at the same height of the center of gravity of an occupant's head. Generally, the center of gravity of most people's head is similar with the height of the top of their eyes. Also, adjust the headrest as close to your head as possible. For this reason, the use of a cushion that holds the body away from the seatback is not recommended. o Do not operate vehicle with the headrests removed as injury to the occupants may occur in the event of an accident. Headrests may provide protection against neck injuries when properly adjusted. o To unlock the seatback, pull the seatback release lever, then pull forward on the seatback panel. o When you return the seatback to its upright position, always be sure it has locked into position by pulling and pushing on the top of the seatback. The purpose of the folding rear seatbacks is to allow you to carry longer objects than could otherwise be accommodated. Do not allow passengers to sit on top of the folded down seatback, while the car is moving as this is not a proper seating position and no seat belts are available for use. This could result in serious injury or death in case of an accident or sudden stop. Objects carried on the folded down seatback should not extend higher than the top of the front seats. This could allow cargo to slide forward and cause injury or damage during sudden stops.
