{CAUTION:

CAUTION: (Continued)

The shoulder belt cannot do its job. 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.

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.

CAUTION: (Continued)

1-6

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

Head Restraints

Adjust the head restraint so that the top of the restraint is at the same height as the top of 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 release button, located on the top of the seatback, while you push the head restraint down.

The second and third row seats have head rests that can be adjusted up and down.

1-7

Rear Seats

Heated Seats

Driver’s Side RSA

Heated Seat Button

shown

On vehicles with rear outboard heated seats, the buttons used to control this feature are located on the Rear Seat Audio (RSA) panel.

M (Heated Seat): To heat the seat cushion, press the

button with the heated seat symbol. A heated seat symbol will be shown in the RSA display

to indicate that the feature is on. Press the button to cycle through the temperature settings of high, medium, and low, and to turn it off. Indicator bars next to the symbol will designate the level of heat selected: three for high, two for medium, and one for low.

The heated seats are off when the ignition is off.

Split Folding Rear Seat

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

1-8

Folding the Seatbacks

The seatbacks are equipped with rearward folding head rests (SUV only). When the seatback is being folded down, the head rest will automatically fold rearward.

To fold the rear seat, do the following:

1. Makesure that nothing is under or in front of the seat.

2. Pull up on the strap loop located at the rear of the seat cushion and pull the seat cushion up and fold it forward.

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.

3. Pull the seatback forward and fold it down until it is ﬂat.

If the seatback cannot fold ﬂat because it interferes with the cushion, try moving the front seat forward and/or bringing the front seatback more upright.

4. Repeat the steps for the other half of the split bench seat.

{CAUTION:

Using the third row seating position while the second row is folded, or folded and tumbled, could cause injury in a sudden stop or crash. Be sure to return the seat to the passenger seating position. Push and pull on the seat to make sure it is locked into place.

1-9

Returning the Seats 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.

{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.

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

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

2. Lower the seat cushion until it latches into position.

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

4. Return the head rest (SUV only) to the upright position.

Third Row Seat

Entering or Exiting the Third Row Seat

If your vehicle has a third row seat, it is intended for 2 passengers and has only 2 designated seating positions.

You must fold the second row seat down before entering or exiting the third row. See “Folding the Seatbacks” under Split Folding Rear Seat on page 1-8 earlier in this section for instructions.

The third row seatback can be folded and the entire seat can be tilted or removed from the vehicle.

3. Pull up on the lever labeled 1 to return the seatback to its upright position.

4. Push and pull on the seat to make sure it is locked into place. The seatback cannot be raised to the upright position unless the seat is secured to the ﬂoor.

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.

1-16

{CAUTION:

People riding on the tailgate (if equipped) can easily lose their balance and fall even when the vehicle is operated at low speeds. Falling from a moving vehicle may result in serious injuries or death.

{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 3-33.

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!

1-17

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.

1-18

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...

1-19

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.

1-20

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.

1-21

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 1-36 or Infants and Young Children on page 1-39. 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.

1-22

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.

1-23

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.

1-24

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.

1-25

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.
