Seat, seatbelt and SRS airbags
1-8
Rear seats
WARNING
Seatbelts provide maximum restraint when
the occupant sits well back and upright in the
seat. Do not put cushions or any other materi-
als between occupants and seatbacks or seat
cushions. If you do so, the risk of sliding
under the lap belt and of the lap belt sliding
up over the abdomen will increase, and both
can result in serious internal injury or death.
WARNING
Never stack luggage or other cargo higher
than the top of the seatback because it could
tumble forward and injure passengers in the
event of a sudden stop or accident.
