How to Use this Manual

Many people read their owner’s manual from beginning to end when they first receive their new vehicle. If you do this, it will help you learn about the features and controls for your vehicle. In this manual, you’ll find that pictures and words work together to explain things quickly.

Safety Warnings and Symbols

You will find a number of safety cautions in this book. We use a box and the word CAUTION to tell you about things that could hurt you if you were to ignore the warning.

CAUTION:

These mean there is something that could hurt you or other people.

In the caution area, we tell you what the hazard is. Then we tell you what to do to help avoid or reduce the hazard. Please read these cautions. If you don’t, you or others could be hurt.

vii

You will also find a circle with a slash through it in this book. This safety symbol means “Don’t,” “Don’t do this” or “Don’t let this happen.”

Vehicle Damage Warnings

Also, in this book you will find these notices:

NOTICE:

These mean there is something that could damage your vehicle.

In the notice area, we tell you about something that can damage your vehicle. Many times, this damage would not be covered by your warranty, and it could be costly. But the notice will tell you what to do to help avoid the damage.

When you read other manuals, you might see CAUTION and NOTICE warnings in different colors or in different words.

You’ll also see warning labels on your vehicle. They use the same words, CAUTION or NOTICE.

Seats and Seat Controls

This section tells you about the seats -- how to adjust them, and fold them up and down.

Manual Front Seat

CAUTION:

You can lose control of the vehicle if you try to adjust a manual driver’s seat while the vehicle is moving. The sudden movement could startle and confuse you, or make you push a pedal when you don’t want to. Adjust the driver’s seat only when the vehicle is not moving.

Move the lever under the front of the manual seat up to unlock it. Slide the seat to where you want it. Then release the lever and try to move the seat with your body to make sure the seat is locked into place.

1-2

Manual Lumbar Support (If Equipped)

If you have this feature, there will be a knob on the outside of the driver’s bucket seat.

Turn the knob toward the front of the vehicle to increase lumbar support and toward the rear of the vehicle to decrease lumbar support.

Reclining Seatbacks (Bucket Seats or 60/40 Bench)

T o adjust the front seatback, lift the lever on the outside of the seat.

Release the lever to lock the seatback where you want it. Pull up on the lever and the seat will go to an upright position.

1-3

But don’t have a seatback reclined if your vehicle is moving.

CAUTION:

Sitting in a reclined position when your vehicle is in motion can be dangerous. Even if you buckle up, your safety belts can’t do their job when you’re reclined like this.

The shoulder belt can’t do its job because it won’t be against your body. Instead, it will be in front of you. In a crash you could go into it, receiving neck or other injuries.

The lap belt can’t 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.

1-4

Seatback Latches (Regular or Extended Cab Only)

CAUTION:

The front seatback folds forward to let people get into the rear seat or to access the storage area behind the seat.

T o fold the front seatback forward, push the lever on the side of the seat rearward and pull the seatback forward.

T o return the seatback to the upright position, push the seatback all the way back until the latch catches. If the seatback was reclined before being folded forward, it will return to the reclined position.

If the seatback isn’t locked, it could move forward in a sudden stop or crash. That could cause injury to the person sitting there. Always press rearward on the seatback to be sure it is locked.

1-5

Easy Entry Seat (Extended Cab Models)

The right front bucket or split-bench seat of your vehicle makes it easy to get in and out of the rear vehicle area.

Tilt the right front seatback completely forward and the whole seat will slide forward.

Move the seatback to its original position after someone gets into the rear seat area. Then move the seat rearward until it locks.

CAUTION:

Jump Seat (Extended Cab Models)

Your extended cab pickup has a jump seat in the rear area.

If an easy entry right front seat isn’t locked, it can move. In a sudden stop or crash, the person sitting there could be injured. After you’ve used it, be sure to push rearward on an easy entry seat to be sure it is locked.

Tilt the seatback completely forward again to get out.

1-6

T o fold the jump seat down, pull down on the pull tab on the bottom of the seat until the seat is in place, then move the seatback to a vertical position. T o store the seat, fold the seatback down on the cushion, then push the entire seat up until it is flush with the trim panel.

Don’t let the safety belts be damaged by the hinges or the latches. Safety belts should be folded and stored between the seat cushion and seatback.

Rear Seat (Crew Cab

T o tilt the rear seat forward, pull forward on the lever located at the base of the seatback.

Safety Belts: They’re 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.

And it explains the air bag system.

CAUTION:

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.

Don’t let anyone ride where he or she can’t wear a safety belt properly. If you are in a crash and you’re not wearing a safety belt, your injuries can be much worse. You can hit things inside the vehicle or be ejected from it. You 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 passengers’ belts are fastened properly too.

Your vehicle has a light that comes on as a reminder to buckle up. See “Safety Belt Reminder Light” in the Index.

In most states and Canadian provinces, the law says to wear safety belts. Here’s why: They work.

1-7

You never know if you’ll be in a crash. If you do have a crash, you don’t know if it will be a bad one.

A few crashes are mild, and some crashes can be so serious that even buckled up a person wouldn’t 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 30 years of safety belts in vehicles, the facts are clear. In most crashes buckling up does matter ... a lot!

Why Safety Belts Work

When you ride in or on anything, you go as fast as it goes.

T ake the simplest vehicle. Suppose it’s just a seat on wheels.

1-8

Put someone on it. Get it up to speed. Then stop the vehicle. The rider

doesn’t stop.

1-9

The person keeps going until stopped by something. In a real vehicle, it could be the windshield ...

1-10

or the instrument panel ...

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’s why safety belts make such good sense.

Here Are Questions Many People Ask About Safety Belts

Won’t I be trapped in the vehicle after an

accident if I’m wearing a safety belt?

-- and the Answers

A: You could be -- whether you’re wearing a safety

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

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

wear safety belts?

A: Air bags are in many vehicles today and will

be in most of them in the future. But they are supplemental systems only; so they work with safety belts system ever offered for sale has required the use of safety belts. Even if you’re in a vehicle that has air bags, you still have to buckle up to get the most protection. That’s true not only in frontal collisions, but especially in side and other collisions.

-- not instead of them. Every air bag

1-11

Q: If I’m 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’re in an

accident your passengers can be hurt. Being a good driver doesn’t 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

Adults

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 the part of this manual called “Children.” Follow those rules for everyone’s protection.

First, you’ll want to know which restraint systems your vehicle has.

We’ll start with the driver position.

Driver Position

This part describes the driver’s restraint system.

Lap-Shoulder Belt

The driver has a lap-shoulder belt. Here’s how to wear it properly.

1. Close and lock the door.

2. Adjust the seat so you can sit up straight. T o see how , see “Seats” in the Index.

1-12

3. Pick up the latch plate and pull the belt across you. Don’t let it get twisted.

The 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.

4. 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 isn’t long enough, see “Safety Belt Extender” at the end of this section.

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.

5. T o make the lap part tight, pull down on the buckle end of the belt as you pull up on the shoulder belt.

1-13

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. And you’d be less likely to slide under the lap belt. If you slid under it, the belt would apply force at 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 safety belt locks if there’s a sudden stop or crash, or if you pull the belt very quickly out of the retractor.

1-14

Q: What’s wrong with this?

A: The shoulder belt is too loose. It won’t give nearly

as much protection this way.

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.

1-15

Q: What’s wrong with this?

A: The belt is buckled in the wrong place.

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

1-16

Q: What’s wrong with this?

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

be worn over the shoulder at all times.

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. You could also severely injure internal organs like your liver or spleen.
