Index

A good place to quickly locate information about the vehicle is the Index in the back of the manual. It is an alphabetical list of what is in the manual and the page number where it can be found.

Safety Warnings and Symbols

There are a number of safety cautions in this book. We use a box and the word CAUTION to tell about things that could hurt you if you were to ignore the warning.

{CAUTION:

These mean there is something that could hurt you or other people.

In the caution area, we tell you what the hazard is. Then we tell you what to do to help avoid or reduce the hazard. Please read these cautions. If you do not, you or others could be hurt.

You will also ﬁnd a circle with a slash through it in this book. This safety symbol means “Do Not,” “Do Not do this” or “Do Not let this happen.”

iii

Vehicle Damage Warnings

Also, in this manual you will ﬁnd these notices:

Notice: These mean there is something that could damage your vehicle.

A notice tells about something that can damage the vehicle. Many times, this damage would not be covered by your vehicle’s warranty, and it could be costly. But the notice will tell what to do to help avoid the damage.

When you read other manuals, you might see CAUTION and NOTICE warnings in different colors or in different words.

There are also warning labels on the vehicle. They use the same words, CAUTION or NOTICE.

Vehicle Symbols

The vehicle has components and labels that use symbols instead of text. Symbols are shown along with the text describing the operation or information relating to a speciﬁc component, control, message, gage, or indicator.

If you need help ﬁguring out a speciﬁc name of a component, gage, or indicator, reference the following topics:

• Seats and Restraint Systems in Section 1

Section 1 Seats and Restraint Systems

1-1

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 Seats

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

horizontal control forward or rearward.

• Raise or lower the front part of the seat cushion by

moving the front of the horizontal control up or down.

• Raise or lower the rear part of the seat cushion by

moving the rear of the horizontal control up or down.

• Raise or lower the entire seat by moving the entire

horizontal control up or down.

If the seats have power reclining seatbacks, the control used to operate them is located behind the power seat control on the outboard side of the seats. See “Power Reclining Seatbacks” under Reclining Seatbacks on page 1-5.

Manual Lumbar

If your vehicle has this feature, there is a knob located on the outboard side of the driver’s seat.

Turn the top of the knob toward the front of the vehicle to increase lumbar support. Turn the top of the knob toward the rear of the vehicle to decrease lumbar support.

1-3

Power Lumbar

Your vehicle may have power lumbar on the driver’s and front passenger’s seats.

The seatback lumbar support can be adjusted by moving the control located on the outboard side of the seat cushions.

To increase or decrease support, hold the control forward or rearward.

Keep in mind that as your seating position changes, as it may during long trips, so should the position of your lumbar support. Adjust the seat as needed.

Heated Seats

Your vehicle may have heated front seats. The buttons used to control this feature are located on the front door armrests. The engine must be running for the heated seat feature to work.

To heat the entire seat, press the horizontal button with the heated seat and seatback symbol. Press the button to cycle through the temperature settings of high, medium, and low and to turn the heated seat off. The indicator lights above the button will come on to designate the level of heat selected: three for high, two for medium, and one for low. The low setting warms the seatback and seat cushion until the seat temperature is near body temperature. The medium and high settings heat the seatback and seat cushion to a slightly higher temperature. You will be able to feel heat in about two minutes.

1-4

To heat only the seatback, press the vertical button with the heated seatback symbol. An indicator light on the button will come on to designate that only the seatback is being heated. Additional presses will cycle through the heat levels for the seatback only.

The feature will shut off automatically when the ignition is turned off.

Reclining Seatbacks

Manual Reclining Seatbacks

{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.

If the seats have manual reclining seatbacks, the lever used to operate them is located on the outboard side of the seats(s).

1-5

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.

Power Reclining Seatbacks

If your seats have power reclining seatbacks, use the vertical power seat control located on the outboard side of the seat(s).

• To recline the seatback, press the control toward

the rear of the vehicle.

• To raise the seatback, press the control toward the

front of the vehicle.

1-6

{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. 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.

1-7

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 button, located on the top of the seatback, and push the head restraint down.

1-8

Rear Seats

Rear Seat Operation

Flip and Fold Second Row Seats (Five-Passenger)

Your vehicle may have ﬂip and fold second row seats which provide additional cargo space.

To ﬂip and fold the seat(s), do the following:

1. Pull up on the loop located where the seat cushion meets the seatback and ﬂip the seat cushion 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.

2. Lift the lever, located on the outboard side of the seatback, and fold the seatback forward. The head restraint will automatically fold out of the way as the seatback is folded down.

1-9

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

{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.

1. Lift the seatback until it locks into the upright position. Push and pull on the seatback to make sure it is locked.

2. Return the head restraints to the upright position by reaching behind the seat and pulling it forward until it locks into place. Push and pull on the head restraint to make sure that it is locked.

3. Flip the seat cushion back into place.

1-10

Fold and Tumble Second Row Seats (Seven-Passenger)

Your vehicle may have a second row 65/35 split bench seat which may be folded and tumbled for access to the third row seats.

To fold and tumble the seat(s), do the following:

1. Push the head restraints down fully.

2. Fold the seatback ﬂat on the seat by pulling up on the front part of the lever, located on the outboard side of the seat, and indicated as 1 on the handle and side cover.

3. Pull up on the rear part of the lever indicated as 2 on the handle and side cover to release the rear set of seat hooks from the ﬂoor pins.

4. Tumble the seat forward.

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

1. Tumble the seat rearward to reengage the rear seat hooks to the ﬂoor pins.

{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.

2. Try to raise the seat to check that it is locked down.

1-11

3. Lift the seatback up to return it to the 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.

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

Third Row Seat (Seven-Passenger)

{CAUTION:

Be sure to return the seat to the passenger seating position when ﬁnished. Push and pull on the seat to make sure it is locked in place. Never use the third row seating position while the second row is folded or folded and tumbled. This could cause injury in a sudden stop or crash.

To enter the third row seat, you must fold and tumble the second row seat following the instructions given previously.

1-12

If you are exiting the third row with no assistance, do the following:

1. Pull the handle, located on the center of the second row seatback, up to release the seatback and fold the seatback forward.

2. Pull the back of the seat lever, located on the outboard side of the seat and indicated with the number 2, to tumble the seat forward.

1-13

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 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 3-34.

1-14

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

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 bad 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 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 is just a seat on wheels.

1-15

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

does not stop.

1-16

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

or the instrument panel...

1-17

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.

Questions and Answers About Safety Belts

Q: Will I be trapped in the vehicle after an accident

if I am wearing a safety belt?

A: You could be — whether you are wearing a safety

belt or not. But you can unbuckle a safety belt, even if you are 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 airbags, why should I have to

wear safety belts?

A: Airbags 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 — not instead of them. Every airbag system ever offered for sale has required the use of safety belts. Even if you are in a vehicle that has airbags, you 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.

1-18

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 an

accident — even one that is not your fault — you and your passengers 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.

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 Older Children on page 1-32 or Infants and Young Children on page 1-34. Follow those rules for everyone’s protection.

First, you will want to know which restraint systems your vehicle has.

We will start with the driver position.

Driver Position

Lap-Shoulder Belt

The driver has a lap-shoulder belt. Here is 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.

3. Pick up the latch plate and pull the belt across you. Do not 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.

1-19

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 is not long enough, see Safety Belt Extender on page 1-31.

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. To make the lap part tight, pull up on the shoulder belt.

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 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 is a sudden stop or crash, or if you pull the belt very quickly out of the retractor.

1-20

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 against your body.

1-21

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 at the pelvic bones. This could cause serious internal injuries. Always buckle your belt into the buckle nearest you.

1-22

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.

1-23

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 to ﬁx it.
