Front Seats

Manual Seats

{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.

If your vehicle has a manual bucket or a split bench seat, you can adjust it with this lever located at the front of the seat.

Lift the lever to unlock the seat. Using your body, slide the seat to where you want it and release the lever. Try to move the seat with your body to make sure the seat is locked into place.

1-3

Power Seats

If your vehicle has a power seat, you can adjust it with these controls located on the outboard sides of the seats.

• Raise or lower the front of the seat cushion by

raising or lowering the forward edge of the horizontal control.

• Move the seat forward or rearward by moving the

whole horizontal control forward or rearward.

• Raise or lower the rear of the seat cushion by

raising or lowering the rear edge of the horizontal control.

• Moving the whole horizontal control up or down

raises or lowers the entire seat cushion.

If your vehicle has power reclining seats, you can use the vertical control to adjust the angle of the seatback. Move the reclining front seatback rearward or forward by moving the control toward the rear or the front of the vehicle. See

Reclining Seatbacks on page 1-6

1-4

Power Lumbar

You can increase or decrease lumbar support in an area of the lower seatback.

To increase support, press and hold the front of the control. To decrease support, press and hold the rear of the control. Let go of the control when the lower seatback reaches the desired level of support.

You can also reshape the side wing area of the lower seatback for more lateral support.

To increase support, press and hold the top of the control. To decrease support, press and hold the bottom of the control. Let go of the control when the lower seatback reaches the desired level of support.

Your vehicle may have a memory function which allows seat settings to be saved and recalled. See

Seat on page 2-69

for more information.

1-5

Heated Seats

If your vehicle has this feature, the button used to control the driver’s heated seat is located on the driver’s door panel. The button used to control the passenger’s heated seat is located on the passenger’s door panel.

To heat the entire seat, press the horizontal button. Press the button to cycle through the temperature settings of high, medium, and low. The indicator light will glow to indicate the level of heat selected.

To heat only the seatback, press the vertical button with the heated seatback symbol. An indicator light on the button will glow to designate that only the seatback is being heated.

The engine must be running for them to operate. The heated front seats will be canceled after the ignition

is turned off. If you still want to use the heated front seat feature after you restart your vehicle, you will need to press the heated seat button again.

Reclining Seatbacks

To adjust the front seatback, lift the manual lever located on the outboard side of the seat. Release the lever to lock the seatback where you want it. Lift the lever again without pushing on the seatback and the seatback will go to an upright position.

If your vehicle has power seats with a power recliner, see

Power Seats on page 1-4

how to operate the reclining seatback feature.

for further information on

1-6

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. 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.

1-7

Head Restraints

Adjust your head restraint so that the top of the restraint is closest to the top of your head. This position reduces the chance of a neck injury in a crash.

To raise the head restraint pull up on the head restraint. On some models the head restraints tilt forward and

rearward also.

The rear seat head restraints in your vehicle may be adjustable. They work the same as the front seat head restraints, except they do not tilt forward and rearward.

Seatback Latches

{CAUTION:

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.

The seatbacks fold forward to let you access the rear of the cab.

To fold a front seatback forward, lift the lever at the base of the seat to release the seatback.

The lever is located on the outboard side of the seat cushion.

To return the seatback to the upright position, push the seatback rearward until it latches. After returning the seatback to its upright position, push and pull on the seatback to make sure it is locked.

1-8

Rear Seats

Rear Seat Operation (Extended Cab)

Folding the Rear Seat

The extended cab’s rear seat can be folded up to provide more cargo space. To fold the seat do the following:

1. Pull forward on the release strap located under the rear seat cushion.

2. Fold the seat cushion upward until it latches with the seatback.

3. Push and pull on the seat to make sure the seat is secure.

The extended cab’s rear seat can also be folded open for more seating space. To use the seat do the following:

1. Push rearward on the seat cushion while pulling up on the release strap under the seat cushion. Pull the seat cushion downward until it latches.

2. After pulling the seat cushion down, pull up on it to make sure it is locked.

Rear Seat Operation (Crew Cab)

The second row rear seat has a 60/40 split seat. Either side of the rear seat may be folded down to give you more cargo space.

Make sure that nothing is under or in front of the seat and that the head restraints are completely lowered.

1-9

To fold the rear seat, do the following:

1. Pull up on the strap loop at the rear of the seat cushion. Then, pull the seat cushion up and fold it forward.

2. After folding the seat cushion fully forward, pull the seatback forward and fold the seatback down untilit is ﬂat. If the seatback cannot fold ﬂatbecauseit interferes with the cushion, try moving the frontseat forward and/or bringing the front seat more upright. The lever at the base of the seatmustbeturned rearward to release the seatback.

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.

{CAUTION:

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.

{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.

Your vehicle has a light that comes on as a reminder to buckle up. See

Safety Belt Reminder Light on page 3-36

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

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.

They work

1-11

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.

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

1-12

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

doesn’t stop.

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

Questions and Answers About Safety Belts

Q: Won’t I be trapped in the vehicle after an

accident if I’m wearing a safety belt?

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.

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 safety belts – not instead of them. Every air bag 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.

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 – even one that isn’t your fault – you and 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

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 or

Infants and Young Children on page 1-35

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.

Older Children on page 1-33

. Follow

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. To see how, see “Seats” in the Index.

1-16

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

Extender on page 1-32

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

1-17

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

1-18

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.

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.

1-19

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.

1-20

Q: What’s wrong with this?

A: The belt is over an armrest.

{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. Be sure the belt goes under the armrests.

1-21

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.

1-22

Q: What’s wrong with this?

A: The belt is twisted across the body.

{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.

1-23

To unlatch the belt, just push the button on the buckle. The belt should go back out of the way.

Before you close the door, be sure the belt is out of the way. If you slam the door on it, you can damage both the belt and your vehicle.

Safety Belt Use During Pregnancy

Safety belts work for everyone, including pregnant women. Like all occupants, they are more likely to be seriously injured if they don’t wear safety belts.

A pregnant woman should wear a lap-shoulder belt, and the lap portion should be worn as low as possible, below the rounding, throughout the pregnancy.
