Seats and Seat Controls

This section tells you about the seats -- how to adjust them, and fold them up and down. It also tells you about reclining front seatbacks and head restraints.

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.

yellowblue

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

Lift the lever at the front of the seat to unlock it. Using your body, slide the seat to where you want it. Then, release the lever and try to move the seat with your body in order to make sure the seat is locked into place.

Move the reclining front seatback rearward by moving the button toward the rear of the vehicle. Move the seatback forward by moving the button toward the front of the vehicle. See “Reclining Seatbacks” in the Index for further information.

1-4

yellowblue

Power Lumbar Control (If Equipped)

If you have power lumbar adjustment, you can increase or decrease lumbar support in an area of the lower seatback.

T o increase support, press and hold the front of the rocker switch. Let go of the switch when the lower seatback reaches the desired level of support.

T o decrease support, press and hold the rear of the rocker switch. Let go of the switch when the lower seatback reaches the desired level of support.

T o decrease support, press and hold the bottom of the rocker switch. Let go of the switch when the lower seatback reaches the desired level of support.

1-5

yellowblue

Memory Seat (If Equipped)

The memory function controls the driver’s seat cushion and recliner positions.

It does not store the lumbar or back support positions.

T o set your memory seat:

1. Adjust the driver’s seat to your desired position.

2. Press the SET button and then press the 1 or 2 button of the memory control within five seconds.

When your vehicle is in PARK (P), press the 1 or 2 side of the memory control to recall the seat setting.

T o do the same thing for a second driver, follow the preceding steps, but press the other number of the memory control.

1-6

yellowblue

Heated Front Seats (If Equipped)

If your vehicle has heated front seats, the ignition must be in RUN for them to operate.

The control for the driver’s side heated seat is located on the driver’s side door panel. The control for the passenger’s side heated seat is located on the passenger’s side door panel.

T o activate the heated seats, press the button once for the HI heat setting. Press the button again for the LO heat setting. T o turn off the heated seats, press the button a third time. An indicator light on the control will illuminate for each heat setting anytime the heated seats are operating.

Reclining Seatbacks

T o adjust the front seatback, lift the lever upward. Release the lever to lock the seatback where you want it. Lift the lever again upward and the seatback will go to an upright position.

If your vehicle has power seats with a power recliner, see “Power Seats” in the Index for further information on how to operate the reclining seatback feature.

1-7

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

yellowblue

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.

1-8

yellowblue

Head Restraints

Slide the head restraint up or down so that the top of the restraint is closest to the top of your ears. This position reduces the chance of a neck injury in a crash.

On some models, the head restraints tilt forward and rearward also.

T o tilt the head restraints forward, grasp the top of the restraint and move it forward to where you want it to go until you hear a click. It will then be locked into that position until you need to move it again. Pulling it forward past the last position will allow the restraint to return to its upright position.

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.

T o fold a front seatback forward, pull this lever forward and fold the seatback forward.

T o return the seatback to the upright position, just push the seatback rearward until it latches. After returning the seatback to its upright position, pull the seatback forward to make sure it is locked.

1-9

yellowblue

Easy Entry Seat (Extended Cab Only)

CAUTION:

If any easy entry seat isn’t locked, it can move. In a sudden stop or crash, the person sitting there could be injured. And, even if there is no crash or sudden stop, a driver sitting in an unlocked easy entry seat could be startled by the sudden movement and hit the wrong control or pedal, causing an accident. After you’ve used it, be sure to push rearward on any easy entry seat to be sure it is locked.

The manual driver side front bucket seat and the manual driver side split bench seat of your vehicle have an easy entry feature. This makes it easy to get in and out of the rear seat.

T o operate the seat, pull forward on the top of this lever and tilt the seatback forward toward the front of the vehicle.

When you do, the seat bottom will release. Just pull or push the seat forward until it stops.

T o return the seat to its regular position, return the seatback to its upright position, then push the whole seat rearward until it latches.

After returning the seat to its regular position, try to move the seat with your body in order to make sure the seat is locked into place.

1-10

Rear Seat (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:

1. Pull forward on the release strap under the rear seat cushion, on the passenger’s side.

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.

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:

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.

yellowblue

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” in the Index.)

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

1-12

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.

yellowblue

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

1-13

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

doesn’t stop.

1-14

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

or the instrument panel ...

1-15

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

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.

1-17

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 (to see how, see “Seats” in the Index) so you can sit up straight.

yellowblue

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.

1-18

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.

yellowblue

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.

1-19

Q: What’s wrong with this?

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

as much protection this way.

yellowblue

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.

1-20

Q: What’s wrong with this?

A: The belt is buckled in the wrong place.

yellowblue

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.

1-21

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.

yellowblue

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.

yellowblue

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

T o 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.

yellowblue

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.
