The shoulder belt should fit against your body. The shoulder belt is too loose. It won’t give nearly as much protection this way.

The belt force would then be applied at the abdomen, not at the pelvic bones, and that could cause serious or fatal injuries.
Page 45 What’s 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 aren’t as strong as shoulder bones.
Page 46 What’s 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.
Page 47: Safety Belt Use During Pregnancy

The driver’s side impact air bag is in the side of the driver’s seatback closest to the door. The driver’s frontal air bag is in the middle of the steering wheel.
Page 52 CAUTION: If something is between an occupant and an air bag, the bag might not inflate properly or it might force the object into that person causing severe injury or even death. The path of an inflating air bag must be kept clear. Don’t put anything between an occupant and an air bag, and don’t attach or put anything on the steering wheel hub or on or near any other air bag...

Rear Safety Belt Comfort Guides for Children and Small Adults Rear shoulder belt comfort guides will provide added safety belt comfort for older children who have outgrown booster seats and for small adults. When installed on a shoulder belt, the comfort guide better positions the belt away from the neck and head.

Page 65: Children
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 66 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 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 lb.
Page 67 CAUTION: Children who are up against, or very close to, any air bag when it inflates can be seriously injured or killed. Air bags plus lap shoulder belts offer outstanding protection for adults 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.
Page 68 What are the different types of add child restraints? CAUTION: on child restraints, which are purchased by the vehicle’s owner, are available in four basic types. Newborn infants need complete support, Selection of a particular restraint should take into including support for the head and neck. This is necessary because a newborn infant’s neck is consideration not only the child’s weight, height weak and its head weighs so much compared...
Page 69: Restraint Systems For Children
Restraint Systems for Children 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 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 71 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 child restraint system is a portable one, which is purchased by the vehicle’s owner.
Page 72: Where To Put The Restraint
When choosing a child restraint, be sure the child restraint is designed to be used in a vehicle. If it is, CAUTION: it will have a label saying that it meets federal motor vehicle safety standards. A child in a rear facing child restraint can be Then follow the instructions for the restraint.
Page 73: Top Strap
Top Strap Some child restraints have a top strap, or “top tether.” It can help restrain the child restraint during a collision. For it to work, a top strap must be properly anchored to the vehicle. Some top strap equipped child restraints are designed for use with or without the top strap being anchored.
Page 74 Once you have the top strap anchored, you’ll be ready to secure the child restraint itself. Tighten the top strap when and as the child restraint manufacturer’s instructions say. Yukon XL Denali models: A child restraint with a top strap should only be used in the second or third row. Don’t use a child restraint with a top strap in the front seat because there’s no place to anchor the top strap.

Page 76 In order to use the system, you need either a forward facing child restraint that has attaching points (B) at its base and a top tether anchor (C), or a rear facing child restraint that has attaching points (B), as shown here. With this system, use the LATCH system instead of the vehicle’s safety belts to secure a child restraint.

Page 85: Older Children
Older Children What is the proper way to wear safety belts? If possible, an older child should wear a 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 86 CAUTION: Never do this. Here two children are wearing the same belt. The belt can’t 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...
Page 87 CAUTION: Never do this. Here a child is sitting in a seat that has a 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.

Page 205: Defensive Driving
Defensive driving really means “be ready for anything.” On city streets, rural roads or freeways, it means “always expect the unexpected.” Assume that pedestrians or other drivers are going to be careless and make mistakes. Anticipate what they might do. Be ready for their mistakes. Rear end collisions are about the most preventable of accidents.

Drunken Driving The obvious way to solve the leading highway safety problem is for people never to drink alcohol and then Death and injury associated with drinking and driving is drive. But what if people do? How much is “too much” a national tragedy.
Page 207 There is a gender difference, too. Women generally have a lower relative percentage of body water than men. Since alcohol is carried in body water, this means that a woman generally will reach a higher BAC level than a man of her same body weight when each has the same number of drinks.

This can help you steer around the obstacle while braking hard. Let’s say the road is wet and you’re driving safely. Suddenly, an animal jumps out in front of you.

If you accelerate too fast, the drive wheels will spin and polish the surface under the tires even more. Your anti lock brakes improve your vehicle’s stability when you make a hard stop on a slippery road.

You should probably stay with your vehicle unless you know for sure that you are near help and you can hike through the snow. Here are some things to do to summon help and keep yourself and your passengers safe: Turn on your hazard flashers.
Page 243 CAUTION: Snow can trap exhaust gases under your vehicle. This can cause deadly CO (carbon monoxide) gas to get inside. CO could overcome you and kill you. You can’t see it or smell it, so you might not know it is in your vehicle. Clear away snow from around the base of your vehicle, especially any that is blocking your exhaust pipe.
