    Why Safety Belts Work 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 you do have Aren’t safety belts for kids? a crash, you don’t know if it will be a bad one.

  • Page 20: How To Wear Safety Belts Properly

    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. If a child will be riding in your vehicle, see Older Children on page 1-27 or Infants and Young Children on page 1-30.
  • Page 21 5. Move the shoulder belt height adjuster to the height that is right for you. See Shoulder Belt Height Adjustment on page 1-21. The lap part of the belt should be worn low and snug on 6. To make the lap part tight, pull down on the buckle the hips, just touching the thighs.
  • Page 22 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 23 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 24 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 25 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 26 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 27: Shoulder Belt Height Adjustment

    Shoulder Belt Height Adjustment Before you begin to drive, move the shoulder belt height adjuster to the height that is right for you. Adjust the height so that the shoulder portion of the belt is centered on your shoulder. The belt should be away from your face and neck, but not falling off your shoulder.

  • Page 30: 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.
  • Page 31 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. If the belt is not long enough, see Safety Belt Extender on page 1-26. 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.

    Safety Belt Extender Each position next to the windows has a shoulder belt height adjuster. See Shoulder Belt Height Adjustment on page 1-21. 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 will CAUTION: order you an extender.
  • Page 33: Child Restraints

    Child Restraints What is the proper way to wear safety belts? If possible, an older child should wear a Older Children 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 34 CAUTION: Never do this. Here two children are wearing the same belt. The belt can not properly spread the impact forces. In a crash, the two children can be crushed together and seriously injured. A belt must be used by only one person at a time. What if a child is wearing a lap-shoulder belt, but the child is so small that the shoulder belt is very close to the child’s face or neck?
  • Page 35 CAUTION: 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.
  • Page 36: 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 37 What are the different types of add-on child restraints? Add-on child restraints, which are purchased by the vehicle’s owner, are available in four basic types. Selection of a particular restraint should take into consideration not only the child’s weight, height, and age but also whether or not the restraint will be compatible with the motor vehicle in which it will be used.

CAUTION: (The threshold level can vary, however, with specific vehicle design, so that it can be somewhat above or below this range.) If something is between an occupant and an airbag, the bag might not inflate properly or it Airbags may inflate at different crash speeds.
  • Page 60: How Does An Airbag Restrain

    What Makes an Airbag Inflate? What Will You See After an Airbag Inflates? In an impact of sufficient severity, the airbag sensing system detects that the vehicle is in a crash. After an airbag inflates, it quickly deflates, The sensing system triggers a release of gas from the so quickly that some people may not even realize inflator, which inflates the airbag.
