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 do not want to. Adjust the driver’s seat only when the vehicle is not moving.

Lift the bar located under the front of the seat to unlock it. Slide the seat to where you want it and release the bar. Try to move the seat with your body to be sure the seat is locked in place.

1-2

Power Seat

If your vehicle has front power seat(s), you can adjust them with these controls located at the front center of the seat cushion.

To raise or lower the seat, move the center knob up or down. To move the seat forward or rearward, move the center knob toward the right or left.

To raise or lower the front of the seat cushion, move the right lever up or down. To raise or lower the rear of the seat cushion, move the left lever up or down.

1-3

Reclining Seatbacks

{CAUTION:

The seats have manual reclining seatbacks. The lever used to operate them is located on the inboard side of the seats.

If the seatback is not locked, it could move forward in a sudden stop or crash. That could cause injury to the person sitting there. Always push and pull on the seatback to be sure it is locked.

1-4

To recline the seatback, do the following:

1. Lift the recline lever.

2. Move the seatback to the desired position, then release the lever to lock the seatback in place.

3. Push and pull on the seatback to make sure it is locked.

To return the seatback to an upright position, do the following:

1. Lift the lever fully without applying pressure to the seatback and the seatback will return to the upright position.

2. Push and pull on the seatback to make sure it is locked.

{CAUTION:

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 because it will not 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 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.

Do not have a seatback reclined if your vehicle is moving.

Rear Seats

Rear Seat Operation

Removing the Rear Seat

Disconnect the quick release latch plates for the lap-shoulder belts on the bench seat to be removed.

1. To do this, press the tip of a key into the release hole of the safety belt buckle while pulling up on the safety belt.

2. Locate the pins. On a three passenger seat there are two pins

located on the inboard sides of the rear seats.

Three Passenger Seat Shown

The driver’s side pin has a gray cap with a black “L” marked on it.

1-6

Three Passenger Seat Shown

The passenger’s side pin has a black cap with a white “R” marked on it.

On a four passenger seat, each half of the seat has a set of pins. The driver’s side has a set marked “L”, and the passenger’s side has a set marked “R”.

If the vehicle has ﬂoor mats, the pins will be located under a ﬂap that has been cut into the mat.

3. Pull the pin handle up to disengage the pin from the retaining clip, then pull the pin out.

4. Repeat this procedure for the other pins.

5. Pull the seat rearward about 2 inches (5 cm) and then lift the seat from the ﬂoor rails.

6. Remove the seat from the vehicle.

7. For the ﬁrst row rear seat, stow the safety belt latch by attaching the clip on the safety belt latch to the trim just inside the side door.

For the remaining rear seats, stow the safety belt latch plate on the clip at the window trim.

1-7

Replacing the Rear Seats

{CAUTION:

A seat that is not locked into place properly can move around in a collision or sudden stop. People in the vehicle could be injured. Be sure to lock the seat into place properly when installing it.

{CAUTION:

A safety belt that is improperly routed, not properly attached, or twisted will not provide the protection needed in a crash. The person wearing the belt could be seriously injured. After raising the rear seatback, always check to be sure that the safety belts are properly routed and attached, and are not twisted.

1. Position the seat into the open slots in both rails. Push the seat forward in the rail, hooking both seat bases onto the pins inside of the rails.

2. To install the locking pins at the rear of the seat base, locate the hole in the rail for the pin. If the vehicle has ﬂoor mats, pull the ﬂap that has been cut into the mat.

3. Insert the locking pins into the seat base and push the seat to line up the pins with the base.

On a three passenger seat, the pin with the black cap marked “R” must be installed on the passenger’s side and the pin with the gray cap marked “L” on the driver’s side.

On a four passenger seat, the pins marked “R” must be installed on the half of the seat on the passenger’s side. The pins marked “L” must be installed on the half of the seat on the driver’s side.

1-8

5. Push the pin(s) marked “L” down until they are in the retaining clip.

6. If the vehicle has a ﬂoor mat, put the ﬂap back to its original position.

7. Repeat this procedure for the other seat base.

8. Connect the quick-release latch plates for the lap-shoulder belts by inserting the latch plates into the buckles attached at the outboard positions of the bench seat. Do not twist the belt.

9. Check that all locking pins are locked into place before operating the vehicle.

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:

Do not let anyone ride where he or she cannot wear a safety belt properly. If you are in a crash and you are not wearing a safety belt, your injuries can be much worse. You can hit things inside the vehicle harder or be ejected from it and 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.

{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 indicators as a reminder to buckle your safety belts. See Safety Belt Reminders on page 3-26.

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 mostcrashesarein 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!

1-10

Why Safety Belts Work

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

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

Put someone on it.

1-11

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

1-12

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

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 is why safety belts make such good sense.

1-13

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.

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.

1-14

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 babies. If a child will be riding in your vehicle, see Older Children on page 1-29 or Infants and Young Children on page 1-32. 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.

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

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. 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.

1-15

Q: What is wrong with this?

A: The shoulder belt is too loose. It will not give 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 snugly against your body.

1-16

Q: What is wrong with this?

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

as much protection this way.

{CAUTION:

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.

1-17

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

1-18

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

1-19

Q: What is 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 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.

1-20

Q: What is wrong with this?

A: The belt is behind the body.

{CAUTION:

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.

1-21

Q: What is 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 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/retailer to ﬁx it.

Lap-Shoulder Belt

All seating positions in your vehicle have a lap-shoulder belt. If you are using a rear seating position with a detachable safety belt and the safety belt is not attached, see Rear Seat Operation on page 1-6 for instruction on reconnecting the safety belt to the mini-buckle.

Here is 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.

1-22

If you ever pull the shoulder portion of a passenger belt out all the way, you may engage the child restraint locking feature. If this happens, just let the belt go back all the way and start again.

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 1-28.

Make sure the release button on the buckle is positioned so you would be able to unbuckle the safety belt quickly if necessary.

4. If equipped with a shoulder belt height adjuster, move it to the height that is right for you. Improper shoulder belt height adjustment could reduce the effectiveness of the safety belt in a crash. See “Shoulder Belt Height Adjustment” later in this section.

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.

1-23

To unlatch the belt, push the button on the buckle. The belt should go back out of the way. When the safety belt is not in use, slide the latch plate up the safety belt webbing. The latch plate should rest on the stitching on the safety belt, near the guide loop on the side wall.

Before you close a 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.

Shoulder Belt Height Adjuster

Your vehicle has a shoulder belt height adjuster for the driver and right front passenger position.

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. Improper shoulder belt height adjustment could reduce the effectiveness of the safety belt in a crash.

To move it down, pull on the center adjuster control labeled PULL. You can move the height adjuster up just by pushing up on the shoulder belt guide.

After you move the height adjuster to where you want it, try to move it down without pushing in to make sure it has locked into position.

1-24

Safety Belt Pretensioners

If the GVWR (Gross Vehicle Weight Rating) of your vehicle is below 8,500 lb (3 855 kg) then your vehicle has safety belt pretensioners for the front occupants. You can ﬁnd the GVWR on the certiﬁcation label on the rear edge of the driver’s door. See Loading Your Vehicle on page 4-20 for more information.

Although you cannot see them, 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 they activate in a crash, you will need to get new ones, and probably other new parts for your safety belt system. See Replacing Restraint System Parts After a Crash on page 1-76.

Rear Safety Belt Comfort Guides

Rear shoulder belt comfort guides may provide added safety belt comfort for older children who have outgrown booster seats and for some adults. When installed on a shoulder belt, the comfort guide positions the belt away from the neck and head.

There is one guide for each outside passenger position in the rear seats. Here is how to install a comfort guide to the safety belt:

1. Locate the guide in a pocket on the side of the seatback.

1-25

2. Place the guide over the belt and insert the two edges of the belt into the slots of the guide.

1-26

3. Be sure that the belt is not twisted and it lies ﬂat. The elastic cord must be under the belt and the guide on top.
