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.

To move a manual seat forward or rearward:

1. Lift the bar to unlock the seat.

2. Slide the seat to the desired position and release the bar.

Try to move the seat with your body to be sure the seat is locked in place.

1-2

Power Seats

Power Lumbar

If the vehicle has power seats, the controls used to operate them are located on the outboard side of the seats.

To adjust the seat, do any of the following:

• Move the seat forward or rearward by sliding the

control forward or rearward.

• Raise or lower the front part of the seat cushion

by moving the front of the control up or down.

• Raise or lower the rear part of the seat cushion

by moving the rear of the control up or down.

If your vehicle has this feature, the control is located on the outboard side of the seat(s).

Press and hold the front of the control until you have the desired lumbar support. To decrease lumbar support, press and hold the rear of the control.

1-3

Heated Seats

If your vehicle has this feature, the controls are located on the outboard side of the front seats.

This feature will heat the cushion and back of the seats. Press the top of the switch to turn the heat to the

high setting. Press the bottom of the switch to turn the heat to the low setting. Put the switch in the center position to turn the heat off.

The ignition must be on for the heated seat feature to work. The seat will heat to the last setting if the ignition has been turned off and then turned back on.

The passenger’s safety belt must be fastened for the heated seat feature to work on the passenger’s seat.

Reclining Seatbacks

{CAUTION:

1-4

{CAUTION:

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.

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

To recline the seatback:

1. Lift the recline lever and move the seatback to the desired position, then release the lever to lock the seatback in place.

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

To return the seatback to an upright position:

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.

1-5

{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.

1-6

Head Restraints

Adjust the head restraint so that the top of the restraint is at the same height as the occupant’s head. This position reduces the chance of a neck injury in a crash.

Pull the head restraint up to raise it. To lower the head restraint, press the button, located on the top of the seatback, and push the head restraint down.

1-7

Rear Seats

60/40 Split Bench Seat

The 60/40 split bench seats can be folded to give you more cargo space.

Folding the Seatbacks

To fold the rear seatback(s), do the following:

1. Make sure that nothing is on, under, or in front of the seat.

2. Place your hand under the front of the seat cushion and lift the cushion up while moving it forward.

There is a label below the seat cushion with instructions to aid in seat operation.

1-8

3. Pull the cushion forward until it rests in the footwell.

Notice: Folding a rear seat with the safety belts still fastened may cause damage to the seat or the safety belts. Always unbuckle the safety belts and return them to their normal stowed position before folding a rear seat.

4. Lift the latch on top of the seatback and pull the seatback forward. Fold the seatback down until it is nearly ﬂat.

5. If the seatback will not fold nearly ﬂat, try moving the front seat forward and/or moving the front seatback more upright.

6. Repeat the steps for the other half of the 60/40 split bench seat.

1-9

Returning the Seatbacks to an Upright Position

{CAUTION:

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.

To return the seatback(s) to the upright position, do the following:

1. Lift the seatback up and push it rearward all the way.

2. Place your hand under the front of the seat cushion and lift the cushion while moving it rearward until it latches into position.

3. Pull forward on the seatback and push down on the seat cushion to make sure the seat is securely in place.

Safety Belts

Safety Belts: They Are for Everyone

{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.

1-10

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 3-28.

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!

1-11

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.

1-12

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

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

1-13

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.

1-14

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.

1-15

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 1-30 or Infants and Young Children on page 1-33. 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.

1-16

Q: What is wrong with this?

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

1-17

Q: What is wrong with this?

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

1-18

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.

1-19

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.

1-20

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.

1-21

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.

1-22

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.

1-23

Lap-Shoulder Belt

All seating positions in your vehicle have a lap-shoulder belt.

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.

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.

Engaging the child restraint locking feature may affect the passenger sensing system. See Passenger Sensing System on page 1-62.

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 1-30.

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.

1-24

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.

To unlatch the belt, just push the button on the buckle. 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.

1-25

Shoulder Belt Height Adjuster

Your 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 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, press the release button (A) and move the height adjuster to the desired position. 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 pressing the release button to make sure it has locked into position.

Safety Belt Pretensioners

Your vehicle has safety belt pretensioners for front outboard occupants. 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 1-70.

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.
