2-10

{ WARNING:

Sitting in a reclined position when your vehicle is in motion can be dangerous. Even if you buckle up, your safety belts cannot do their job when you are reclined like this. The shoulder belt cannot do its job. In a crash, you could go into it, receiving neck or other injuries. The lap belt cannot do its job either. In a crash the belt could go up over your abdomen. The belt forces would be there, not at your pelvic bones. This could cause serious internal injuries. For proper protection when the vehicle is in motion, have the seatback upright. Then sit well back in the seat and wear your safety belt properly.

Safety Belts

Safety Belts: They Are for Everyone This part of the manual tells you how to use safety belts properly. It also tells you some things you should not do with safety belts.

{ WARNING:

Do not let anyone ride where a safety belt cannot be worn properly. In a crash, if you or your passenger(s) are not wearing safety belts, the injuries can be much worse. You can hit things inside the vehicle harder or be ejected from the vehicle. You and your passenger(s) can be seriously injured or killed. In the same crash, you might not be, if you are buckled up. Always fasten your safety belt, and check that your passenger(s) are restrained properly too.

{ WARNING:

People riding on the tailgate (if equipped) can easily lose their balance and fall even when the vehicle is operated at low speeds. Falling from a moving vehicle may result in serious injuries or death.

{ WARNING:

It is extremely dangerous to ride in a cargo area, inside or outside of a vehicle. In a collision, people riding in these areas are more likely to be seriously injured or killed. Do not allow people to ride in any area of your vehicle that is not equipped with seats and safety belts. Be sure everyone in your vehicle is in a seat and using a safety belt properly.

Your vehicle has indicators as a reminder to buckle your safety belts. See Safety Belt Reminders on page 4‑32 .

Why Safety Belts Work When you ride in or on anything, you go as fast as it goes.

In most states and in all Canadian provinces, the law requires wearing safety belts. Here is why: You never know if you will be in a crash. If you do have a crash, you do not know if it will be a serious one. A few crashes are mild, and some crashes can be so serious that even buckled up, a person would not survive. But most crashes are in between. In many of them, people who buckle up can survive and sometimes walk away. Without belts they could have been badly hurt or killed. After more than 40 years of safety belts in vehicles, the facts are clear. In most crashes buckling up does matter ... a lot!

Take the simplest vehicle. Suppose it is just a seat on wheels.

Put someone on it.

Get it up to speed. Then stop the vehicle. The rider does not stop.

or the instrument panel...

Questions and Answers About Safety Belts

Q: Will I be trapped in the vehicle after a crash if I

am wearing a safety belt?

A: You could be — whether you are wearing a safety

belt or not. But your chance of being conscious during and after an accident, so you can unbuckle and get out, is much greater if you are belted. And you can unbuckle a safety belt, even if you are upside down.

Q: If my vehicle has airbags, why should I have to

wear safety belts?

A: Airbags are supplemental systems only; so they

work with safety belts — not instead of them. Whether or not an airbag is provided, all occupants still have to buckle up to get the most protection. That is true not only in frontal collisions, but especially in side and other collisions.

or the safety belts! With safety belts, you slow down as the vehicle does. You get more time to stop. You stop over more distance, and your strongest bones take the forces. That is why safety belts make such good sense.

2-20

Q: If I am a good driver, and I never drive far from

home, why should I wear safety belts?

A: You may be an excellent driver, but if you are in a crash — even one that is not your fault — you and your passenger(s) can be hurt. Being a good driver does not protect you from things beyond your control, such as bad drivers. Most accidents occur within 25 miles (40 km) of home. And the greatest number of serious injuries and deaths occur at speeds of less than 40 mph (65 km/h). Safety belts are for everyone.

How to Wear Safety Belts Properly This section 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 infants. If a child will be riding in the vehicle, see Older Children on page 2‑39 or Infants and Young Children on page 2‑42 . Follow those rules for everyone's protection. It is very important for all occupants to buckle up. Statistics show that unbelted people are hurt more often in crashes than those who are wearing safety belts. Occupants who are not buckled up can be thrown out of the vehicle in a crash. And they can strike others in the vehicle who are wearing safety belts.

2-21

First, before you or your passenger(s) wear a safety belt, there is important information you should know.

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 on your abdomen. This could cause serious or even fatal injuries. 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. The shoulder belt locks if there is a sudden stop or crash.

Sit up straight and always keep your feet on the floor in front of you. The lap part of the belt should be worn low and snug on the hips, just touching the thighs.

2-22

Q: What is wrong with this?

{ WARNING:

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 snugly against your body.

A: The shoulder belt is too loose. It will not give as

much protection this way.

2-23

Q: What is wrong with this?

{ WARNING:

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 on 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.

A: The lap belt is too loose. It will not give nearly as

much protection this way.

2-24

Q: What is wrong with this?

{ WARNING:

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 on the pelvic bones. This could cause serious internal injuries. Always buckle your belt into the buckle nearest you.

A: The belt is buckled in the wrong buckle.

2-25

Q: What is wrong with this?

{ WARNING:

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 on the abdomen, not on the pelvic bones, and that could cause serious or fatal injuries. Be sure the belt goes under the armrests.

A: The belt is over an armrest.

2-26

Q: What is wrong with this?

{ WARNING:

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. You could also severely injure internal organs like your liver or spleen. The shoulder belt should go over the shoulder and across the chest.

A: The shoulder belt is worn under the arm. It should

be worn over the shoulder at all times.

2-27

Q: What is wrong with this?

{ WARNING:

You can be seriously injured by not wearing the lap-shoulder belt properly. In a crash, you would not be restrained by the shoulder belt. Your body could move too far forward increasing the chance of head and neck injury. You might also slide under the lap belt. The belt force would then be applied right on the abdomen. That could cause serious or fatal injuries. The shoulder belt should go over the shoulder and across the chest.

A: The belt is behind the body.

2-28

Q: What is wrong with this?

{ WARNING:

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.

A: The belt is twisted across the body.

2-29

Lap-Shoulder Belt If the vehicle is a regular cab, then all seating positions in the vehicle have a lap-shoulder belt. If the vehicle is a crew or extended cab, then all seating positions in the vehicle have a lap-shoulder belt except for the center front passenger position (if equipped), which has a lap belt. See Lap Belt (Crew and Extended Cab) on page 2‑37 for more information. The following instructions explain how to wear a lap-shoulder belt properly.

1. Adjust the seat, if the seat is adjustable, so you

can sit up straight. To see how, see “Seats” in the Index.

2. 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. If this happens, let the belt go back slightly to unlock it. Then pull the belt across you more slowly. If the shoulder portion of a passenger belt is pulled out all the way, the child restraint locking feature may be engaged. If this happens, let the belt go back all the way and start again. Engaging the child restraint locking feature may affect the passenger sensing system, if equipped. See Passenger Sensing System on page 2‑86 for more information.

2-30

If the belt stops before it reaches the buckle, when using the lap-shoulder belt in a rear center seating position of a crew-cab, tilt the latch plate and keep pulling the safety belt until it can be buckled.

3. Push the latch plate into the buckle until it clicks.

Pull up on the latch plate to make sure it is secure. If the belt is not long enough, see Safety Belt Extender on page 2‑38 . If the latch plate will not go fully into the buckle, check if the correct buckle is being used. Position the release button on the buckle so that the safety belt could be quickly unbuckled if necessary.

2-31

4.

If equipped with a shoulder belt height adjuster, move it to the height that is right for you. See “Shoulder Belt Height Adjustment” later in this section.

To unlatch the belt, push the button on the buckle. The belt should return to its stowed position. Before a door is closed, be sure the safety belt is out of the way. If a door is slammed against a safety belt, damage can occur to both the safety belt and the vehicle.

5. To make the lap part tight, pull up on the

shoulder belt. It may be necessary to pull stitching on the safety belt through the latch plate to fully tighten the lap belt on smaller occupants.

2-32

Shoulder Belt Height Adjuster The vehicle has a shoulder belt height adjuster for the driver and right front passenger. Adjust the height so that the shoulder portion of the belt is centered on the shoulder. The belt should be away from the face and neck, but not falling off the shoulder. Improper shoulder belt height adjustment could reduce the effectiveness of the safety belt in a crash.

To move the adjuster down for the regular and crew cabs, squeeze the buttons (A) on the sides of the height adjuster and move the height adjuster to the desired position.

Regular and Crew Cab

On the extended cab, push down on the release button (A) and move the height adjuster to the desired position.

Extended Cab

You can move the adjuster up just by pushing up on the shoulder belt guide. After you move the adjuster to where you want it, try to move it down, without squeezing the buttons for the regular and crew cabs, or without pushing the release button for extended cabs, to make sure it has locked into position.

2-33

Rear Safety Belt Comfort Guides This vehicle may have rear shoulder belt comfort guides. If not, they are available through your dealer. The guides may provide added safety belt comfort for older children who have outgrown booster seats and for some adults. When installed and properly adjusted, the comfort guide positions the belt away from the neck and head.

Safety Belt Pretensioners This vehicle has safety belt pretensioners for front outboard occupants. Although the safety belt pretensioners cannot be seen, they are part of the safety belt assembly. They can help tighten the safety belts during the early stages of a moderate to severe frontal, near frontal, or rear crash if the threshold conditions for pretensioner activation are met. And, if your vehicle has side impact airbags, safety belt pretensioners can help tighten the safety belts in a side crash or a rollover event. Pretensioners work only once. If the pretensioners activate in a crash, they will need to be replaced, and probably other new parts for the vehicle's safety belt system. See Replacing Restraint System Parts After a
