Questions and Answers About Safety Belts Will I be trapped in the vehicle after an accident if I am wearing a safety belt? You could be — whether you are wearing a safety belt or not. But you can unbuckle a safety belt, even if you are upside down.

Page 28 Make sure the release button on the buckle is positioned so you would be able to unbuckle the safety belt quickly if you ever had to. 3. Pick up the latch plate and pull the belt across you. Do not let it get twisted. The lap-shoulder belt may lock if you pull the belt across you very quickly.
Page 29 The lap part of the belt should be worn low and snug on the hips, just touching the thighs. In a crash, this applies force to the strong pelvic bones. And you would be less likely to slide under the lap belt. If you slid under it, the belt would apply force at your abdomen.
Page 30 What is 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. The shoulder belt is too loose. It will not give nearly as much protection this way.
Page 31 What is wrong with this? CAUTION: You can be seriously hurt if your lap belt is too loose. In a crash, you could slide under the lap belt and apply force at your abdomen. This could cause serious or even fatal injuries. The lap belt should be worn low and snug on the hips, just touching the thighs.
Page 32 What is wrong with this? CAUTION: You can be seriously injured if your belt 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.
Page 33 What is 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 fatal injuries.
Page 34 What is wrong with this? CAUTION: You can be seriously injured if you wear the shoulder belt under 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 are not as strong as shoulder bones.
Page 35 What is 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/retailer to ﬁx it.

Page 38: Rear Seat Passengers
Rear Seat Passengers It is very important for rear seat passengers to 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 are not safety belted can be thrown out of the vehicle in a crash.

The shoulder belt should go over the shoulder and across the chest. These parts of the body are best able to take belt restraining forces.
Page 43: Safety Belt Extender
Safety Belt Extender If the vehicle’s safety belt will fasten around you, you should use it. But if a safety belt is not long enough, your dealer/retailer will order you an extender. When you go in to order it, take the heaviest coat you will wear, so the extender will be long enough for you.
Page 44: Child Restraints
Child Restraints What is the proper way to wear safety belts? Older Children An older child should wear a lap-shoulder belt and get the additional restraint a shoulder belt can provide. The shoulder belt should not cross the face or neck. The lap belt should ﬁt snugly below the hips, just touching the top of the thighs.

Page 48 CAUTION: People should never hold a baby in their arms while riding in a vehicle. A baby does not weigh much — until a crash. During a crash a baby will become so heavy it is not possible to hold it. For example, in a crash at only 25 mph (40 km/h), a 12 lb (5.5 kg) baby will suddenly become a 240 lb (110 kg) force...
Page 49 CAUTION: Children who are up against, or very close to, any airbag when it inﬂates can be seriously injured or killed. Airbags plus lap-shoulder belts offer protection for adults and older children, but not for young children and infants. Neither the vehicle’s safety belt system nor its airbag system is designed for them.

Page 51: Child Restraint Systems
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. A young child’s hip bones are still so small that the vehicle’s regular safety belt may not remain low on the hip bones, as it should.

The harness system holds the infant in sometimes with surfaces such as T-shaped place and, in a crash, acts to keep the infant or shelf-like shields.
Page 53 How Should I Use a Child Restraint? A child restraint system is any device designed for use in a motor vehicle to restrain, seat, or position children. A built-in child restraint system is a permanent part of the motor vehicle. An add-on child restraint system is a portable one, which is purchased by the vehicle’s owner.
Page 54 Securing an Add-on Child Restraint in To help reduce the chance of injury, the child restraint must be secured in the vehicle. Child the Vehicle restraint systems must be secured in vehicle seats by lap belts or the lap belt portion of a lap-shoulder belt, or by the LATCH system.
Page 55 Securing the Child Within the Child Restraint CAUTION: There are several systems for securing the child A child can be seriously injured or killed within the child restraint. One system, the three-point harness, has straps that come down in a crash if the child is not properly over each of the infant’s shoulders and buckle secured in the child restraint.
Page 56: Where To Put The Restraint
Where to Put the Restraint CAUTION: (Continued) Accident statistics show that children are safer if they are restrained in the rear rather than the front inﬂating airbag. Be sure the airbag is off seat. We recommend that child restraints be before using a rear-facing child restraint secured in a rear seat including an infant riding in in the right front seat position.

The LATCH system holds a child restraint during Lower Anchors driving or in a crash. This system is designed to make installation of a child restraint easier.
Page 59 Top Tether Anchor Your child restraint may have a single tether (A) or a dual tether (C). Either will have a single attachment (B) to secure the top tether to the anchor. Some child restraints that have a top tether are designed for use with or without the top tether being attached.
