Questions and Answers About How to Wear Safety Belts Properly Safety Belts 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 Will I be trapped in the vehicle after an accident rules for smaller children and babies.
Page 15: Driver Position
Driver Position 3. Pick up the latch plate and pull the belt across you. Do not let it get twisted. The shoulder belt may lock if you pull the belt across you very quickly. If this Lap-Shoulder Belt happens, let the belt go back slightly to unlock it.
Page 16 5. To make the lap part tight, pull down on the buckle end of the belt as you pull up on the shoulder belt. 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.
Page 17 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 18 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.
Page 19 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 20 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 to ﬁx it.
Page 21: Safety Belt Use During Pregnancy
Safety Belt Use During Pregnancy Safety belts work for everyone, including pregnant women. Like all occupants, they are more likely to be seriously injured if they do not wear safety belts. To unlatch the belt, just push the button on the buckle. The belt should go back out of the way.
Page 22: Right Passenger Position
Right Passenger Position The right passenger’s safety belt works the same way as the driver’s safety belt. See Driver Position on page 1-9. Center Passenger Position Lap Belt If your vehicle has a center seat, someone can sit in the center position.
Page 23: Child Restraints
Safety Belt Extender Child Restraints If the vehicle’s safety belt will fasten around you, you Older Children should use it. But if a safety belt is not long enough, your dealer will order you an extender. It is free. When you go in to order it, take the heaviest coat you will wear, so the extender will be long enough for you.
Page 24 What is the proper way to wear safety belts? If possible, 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 26: Infants And Young Children
Infants and Young Children Everyone in a vehicle needs protection! This includes infants and all other children. Neither the distance traveled nor the age and size of the traveler changes the need, for everyone, to use safety restraints. In fact, the law in every state in the United States and in every Canadian province says children up to some age must be restrained while in a vehicle.
Page 27 For most basic types of child restraints, there are many different models available. When purchasing a child restraint, be sure it is designed to be used in a motor vehicle. If it is, the restraint will have a label saying that it meets federal motor vehicle safety standards.
Page 28: 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.
Page 29 A rear-facing infant seat (B) provides restraint with the A forward-facing child seat (C-E) provides restraint for seating surface against the back of the infant. The the child’s body with the harness and also sometimes harness system holds the infant in place and, in a crash, with surfaces such as T-shaped or shelf-like shields.
Page 30 How do child restraints work? 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 31: Top Strap
Top Strap When choosing a child restraint, be sure the child restraint is designed to be used in a vehicle. If it is, it will have a label saying that it meets federal motor Some child restraints have a top strap, or “top tether,” vehicle safety standards.
Page 32 There are no top strap anchors in this vehicle. Do not secure a child seat in this vehicle if a national or local law requires that the top strap be anchored, or if the instructions that come with the restraint say that the top strap must be anchored.
