Additional Safety Information The seat belts and airbags are obviously important parts of your occupant protection system. In addition, you should know that sitting upright, locking the doors, and stowing things properly can also increase your safety and possibly even save your life. Seat-Back Position The seat-backs should be in an upright position for you and your passengers to get the most protection from the seat belts. If you recline a seat-back, you reduce the protective capability of your seat belt. The farther a seat-back is reclined, the greater the risk that you will slide under the belt in a severe crash and be very seriously injured. For information on how to adjust the seat-back, see page 49. Door Locks It is not safe to leave your car doors unlocked. A passenger, especially a child, could open a door and accidentally fall out. Also, there is a greater chance of being thrown out of the car during a crash when the doors are not locked. Driver and Passenger Safety
