It also tells you some things you should not do with safety belts. {CAUTION: Do not let anyone ride where he or she can not wear a safety - 2004 GMC Yukon | Owner's Manual - Page 30
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's why: They work. You never know if you'll be in a crash. If - 2004 GMC Yukon | Owner's Manual - Page 31
Why Safety Belts Work When you ride in or on anything, you go as fast as it goes. Put someone on it. Take the simplest vehicle. Suppose it's just a seat on wheels. 1-25 - 2004 GMC Yukon | Owner's Manual - Page 32
Get it up to speed. Then stop the vehicle. The rider doesn't stop. The person keeps going until stopped by something. In a real vehicle, it could be the windshield... 1-26 - 2004 GMC Yukon | Owner's Manual - Page 33
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's why safety belts make such good sense. 1-27 - 2004 GMC Yukon | Owner's Manual - Page 34
in most of them in the future. But they are supplemental systems only; so they work with safety belts - not instead of them. Every air bag system ever offered for sale has required the use of safety belts. Even if you're in a vehicle that has air bags, you still have to buckle up to get the most - 2004 GMC Yukon | Owner's Manual - Page 35
your vehicle has. We'll start with the driver position. Driver Position This part describes the driver's restraint system. Lap-Shoulder Belt The driver has a lap-shoulder belt.

To make the lap part tight, pull down on the buckle end of the belt as you pull up on the shoulder belt. The safety belt locks if there's a sudden - 2004 GMC Yukon | Owner's Manual - Page 37
's wrong with this? {CAUTION: You can be seriously hurt if your shoulder belt is too loose. In a crash, you would move forward too much, which could increase injury. The shoulder belt should fit against your body. A: The shoulder belt is too loose. It won't give nearly as much protection this way - 2004 GMC Yukon | Owner's Manual - Page 38
is buckled in the wrong place like this. In a crash, the belt would go up over your abdomen. The belt forces would be there, not at the pelvic bones. This could cause serious internal injuries. Always buckle your belt into the buckle nearest you. A: The belt is buckled in the wrong place. 1-32 - 2004 GMC Yukon | Owner's Manual - Page 39
Q: What's wrong with this? {CAUTION: You can be seriously injured if your belt goes over an armrest like this. The belt would be much too high. In a crash, you can slide under the belt. The belt force would then be applied at the abdomen, not at the pelvic bones, and that could cause serious or - 2004 GMC Yukon | Owner's Manual - Page 40

In a crash, your body would move too far forward, which would increase the chance of head and neck injury. Also, the belt would apply too much force to the ribs, which are not as strong as - 2004 GMC Yukon | Owner's Manual - Page 41
wrong with this? {CAUTION: You can be seriously injured by a twisted belt. In a crash, you would not have the full width of the belt to spread impact forces. If a belt is twisted, make it straight so it can work properly, or ask your dealer to fix it. A: The belt is twisted across the body. 1-35 - 2004 GMC Yukon | Owner's Manual - Page 42

Older children who have outgrown booster seats should wear the vehicle's safety belts. If you have the choice, a child should sit in a seat that has a lap-shoulder - 2004 GMC Yukon | Owner's Manual - Page 52
on the child's shoulder, so that in a crash the child's upper body would have the restraint that belts provide. See Rear Safety Belt Comfort Guides for Children and Small Adults on page 1-42. If the child is so small that the shoulder belt is still very close to the child's face or neck, you might - 2004 GMC Yukon | Owner's Manual - Page 53
: Never do this. Here a child is sitting in a seat that has a lap-shoulder belt, but the shoulder part is behind the child. If the child wears the belt in this way, in a crash the child might slide under the belt. The belt's force would then be applied right on the child's abdomen.

including support for the head and neck. This is necessary because a newborn infant's neck is weak and its head weighs so much compared with the rest of its body. In a crash, an infant in a rear-facing seat settles into the restraint, so the crash forces can be distributed across the strongest part - 2004 GMC Yukon | Owner's Manual - Page 57
Child Restraint Systems {CAUTION: The body structure of a young child is quite unlike that of an adult or older child, for whom the safety belts are designed.
