In a belts properly. It also tells you some things you should collision, people riding in these areas are more not do with safety belts.
Page 16: Why Safety Belts Work
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 18 Or it could be the instrument panel. With belts, you slow down as the vehicle does. You get more time to stop. Now, what if you and your passengers were to give that big vehicle a chance to deal with the force of the You stop over more distance, and your strongest bones impact, instead of you? take the forces.
Page 19 Questions and Answers About If I am a good driver, and I never drive far from home, why should I wear safety belts? Safety Belts You may be an excellent driver, but if you are in an accident — even one that is not your fault — you Will I be trapped in the vehicle after an accident and your passengers can be hurt.
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.

To make the belt until the belt is snug. longer, tilt the latch plate and pull it along the belt. Buckle, position and release it the same way as the lap part of a lap-shoulder belt.
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.
Page 32: Safety Belt Extender
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.
Page 38 CAUTION: CAUTION: Newborn infants need complete support, The body structure of a young child is quite including support for the head and neck. unlike that of an adult or older child, for whom This is necessary because a newborn infant’s the safety belts are designed.
Page 39: Child Restraint Systems

The harness system holds the infant in place and, An infant car bed (A), a special bed made for use in a in a crash, acts to keep the infant positioned in motor vehicle, is an infant restraint system designed the restraint.

Page 46: Securing A Child Restraint In A Rear Outside Seat Position
Securing a Child Restraint in a Rear Outside Seat Position (Crew Cab Models) There are no top strap anchors in the rear outside seat positions. Do not secure a child seat in these positions if a national or local law requires that the top strap be anchored, or if the instructions that come with the child restraint say that the top strap must be anchored.

Page 54: Airbag System
Airbag System If you were using a child restraint in a vehicle equipped with a right front passenger’s airbag, turn on the right front passenger’s airbag when you remove the child restraint from the vehicle unless the person who will be sitting there is a member of a passenger airbag risk group.
Page 55 If it says AIR BAG on the middle part of the steering wheel, but it does not say AIR BAG on the instrument panel in front of the right front passenger’s seat, your vehicle has an airbag for the driver only. If it says AIR BAG on the middle part of the steering wheel, but there is no right front passenger seat, your vehicle has an airbag for the driver only.
Page 56 Here are the most important things to know about the airbag system: CAUTION: CAUTION: Airbags inﬂate with great force, faster than the blink of an eye. If you are too close to an inﬂating airbag, as you would be if you were You can be severely injured or killed in a crash leaning forward, it could seriously injure you.

CAUTION: Anyone who is up against, or very close to, any airbag when it inﬂates can be seriously The system checks the airbag electrical system for injured or killed.
Page 58: Where Are The Airbags
Where Are the Airbags? The right front passenger’s airbag is in the instrument panel on the passenger’s side. The driver’s airbag is in the middle of the steering wheel. 1-52...
Page 59 It depends largely on what you hit, the direction of the impact and how quickly your vehicle slows down. 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.
Page 61 In many crashes severe enough to inﬂate the airbag, windshields are broken by vehicle deformation. CAUTION: Additional windshield breakage may also occur from the right front passenger airbag. • Airbags are designed to inﬂate only once. After they When an airbag inﬂates, there is dust in the inﬂate, you will need some new parts for your air.
Page 62: Airbag Off Switch
Airbag Off Switch This switch should only be turned to the off position if the person in the right front passenger’s position is a member of a passenger risk group identiﬁed by the If your vehicle has a right front passenger airbag, it has national government as follows: a switch on the instrument panel that you can use to turn off the right front passenger’s airbag.
Page 63 Medical Condition. A passenger has a medical condition which, according to his or her physician: • causes the passenger airbag to pose a special risk for the passenger; and • makes the potential harm from the passenger airbag in a crash greater than the potential harm from turning off the airbag and allowing the passenger, even if belted, to hit the dashboard or windshield in a crash.
Page 64 The airbag off light will come on to let you know that the right front passenger’s airbag is off. The light will stay on to remind you that the airbag is off. The right front passenger’s airbag will remain off until you turn it back on.
