area of your vehicle that is not equipped with seats and safety belts. Be sure everyone in your vehicle is in a seat and using a safety belt properly. In most states and in all Canadian provinces, the law says to wear safety belts. Here is why: They work. You never know if you will be in a crash - 2005 Cadillac STS | Owner's Manual - Page 15

or the instrument panel... or the safety belts! With safety belts, you slow down as the vehicle does. You get more time to stop. You stop over more distance, and your strongest bones take the forces. That is why safety belts make such good sense. 1-11 - 2005 Cadillac STS | Owner's Manual - Page 18
