up can survive and sometimes walk away. Without belts they could have been badly hurt or killed. After more than 30 years of safety belts in vehicles, the facts are clear. In most crashes buckling up does matter...a lot! Your vehicle has a light that comes on as a reminder to buckle up. See Safety - 2003 GMC Yukon | Owner's Manual - Page 30
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. 1-24 - 2003 GMC Yukon | Owner's Manual - Page 31
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... 1-25 - 2003 GMC Yukon | Owner's Manual - Page 32
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. 1-26 - 2003 GMC Yukon | Owner's Manual - Page 33
air bags, why should I have to wear safety belts? How to Wear Safety Belts Properly This part is only for people of adult size. Be aware that there are special things to know about safety belts and children. And there are different rules for smaller children and babies.

This part describes the driver's restraint system. Lap-Shoulder Belt The driver has a lap-shoulder belt. belt across you. Don't let it get twisted. The shoulder belt may lock if you pull the belt across you very quickly. If this happens, let the belt go back slightly to unlock it. Then pull the belt - 2003 GMC Yukon | Owner's Manual - Page 35
. And you'd be less likely to slide under the lap belt. If you slid under it, the belt would apply force at your abdomen. This could cause serious or even fatal injuries. The shoulder belt should go over the shoulder and across the chest. These parts of the body are best able to take - 2003 GMC Yukon | Owner's Manual - Page 36
'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 - 2003 GMC Yukon | Owner's Manual - Page 37
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. 1-31 - 2003 GMC Yukon | Owner's Manual - Page 38
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 - 2003 GMC Yukon | Owner's Manual - Page 39
your arm. 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 aren't as strong as shoulder bones. You could also severely injure internal organs like your liver - 2003 GMC Yukon | Owner's Manual - Page 40
wrong with this? {CAUTION: You can be seriously injured by a twisted belt. In a crash, you wouldn't 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. 1-34 - 2003 GMC Yukon | Owner's Manual - Page 41
Use During Pregnancy Safety belts work for everyone, including pregnant women. Like all occupants, they are more likely to be seriously injured if they don't wear safety belts.

than in the second row you have a lap belt. To make the belt shorter, pull its free end as shown until the belt is snug. Buckle, position and release it the same way as the lap part of a lap-shoulder belt. If the belt isn't long enough, see Safety Belt Extender on page 1-43. Make sure the - 2003 GMC Yukon | Owner's Manual - Page 44
buckle up! Accident statistics show that unbelted people in the rear seat are hurt more often in crashes than those who are wearing safety belts. Rear passengers who aren't safety belted can be thrown out of the vehicle in a crash. And they can strike others in the vehicle who are wearing safety - 2003 GMC Yukon | Owner's Manual - Page 45
to make sure it is secure. When the shoulder belt is pulled out all the way, it will lock. If it does, let it go back all the way and start again. 3. To make the lap part tight, pull down on the buckle end of the belt as you pull up on the shoulder - 2003 GMC Yukon | Owner's Manual - Page 46

or neck? If the child is sitting in a rear seat outside position, move the child toward the center of the vehicle. See Rear Safety Belt Comfort Guides for Children and Small Adults on page 1-41. If the child is sitting in the second row center position, move the child toward the safety - 2003 GMC Yukon | Owner's Manual - Page 52
: 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. That could cause - 2003 GMC Yukon | Owner's Manual - Page 53
restraints. Young children should not use the vehicle's adult safety belts alone, unless there is no other choice. Instead, they need to use a child restraint. {CAUTION: People should never hold a baby in their arms while riding in a vehicle. A baby doesn't weigh much -- until a crash. During - 2003 GMC Yukon | Owner's Manual - Page 54
and older children, but not for young children and infants. Neither the vehicle's safety belt system nor its air bag system is designed for them. Young children and infants need the protection that a child restraint system can provide. Q: What are the different types of add-on child restraints - 2003 GMC Yukon | Owner's Manual - Page 55
. The restraint manufacturer's instructions that come with the restraint state 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 of an infant's body, the back - 2003 GMC Yukon | Owner's Manual - Page 56
position a child on a continuous flat surface. Make sure that the infant's head rests toward the center of the vehicle. A rear-facing infant seat (B) provides restraint with the seating surface against the back of the infant. The harness system holds the infant in place and, in a crash, acts to keep - 2003 GMC Yukon | Owner's Manual - Page 57
or shelf-like shields. A booster seat (F-G) is a child restraint designed to improve the fit of the vehicle's safety belt system. Some booster seats have a shoulder belt positioner, and some high-back booster seats have a five-point harness. A booster seat can also help a child to see out the window - 2003 GMC Yukon | Owner's Manual - Page 58
or in a booklet, or both. These restraints use the belt system in your vehicle, but the child also has to be secured within the restraint to help reduce the chance of personal injury.

Lower Anchorages and Top Tethers for Children (LATCH System) This system, designed to make installation of child restraints easier, does not use the vehicle's safety belts. Instead, it uses vehicle anchors (A, B) and child restraint attachements to secure the restraints. Some restraints also use - 2003 GMC Yukon | Owner's Manual - Page 66
or killed. Make sure that a LATCH-type child restraint is properly installed using the anchorage points, or use the vehicle's safety belts to secure the restraint.
