2008 GMC Acadia Owner's Manual - Page 21

{CAUTION: It is extremely dangerous to ride in a cargo area, inside or outside of a vehicle. In a collision, people riding in these areas are more likely to be seriously injured or killed. Do not allow people to ride in any 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. Your vehicle has indicators as a reminder to buckle your safety belts. See Safety Belt Reminders on page 3-41. In most states and in all Canadian provinces, the law requires wearing safety belts. Here is why: You never know if you will be in a crash. If you do have a crash, you do not know if it will be a serious one. A few crashes are mild, and some crashes can be so serious that even buckled up, a person would not survive. But most crashes are in between. In many of them, people who buckle up can survive and sometimes walk away. Without belts they could have been badly hurt or killed. After more than 40 years of safety belts in vehicles, the facts are clear. In most crashes buckling up does matter...a lot! 1-17
