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

• Features and Controls in Section 2

• Instrument Panel Overview in Section 3

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 you have this feature,

the power seat controls

are located on the

outboard side of the front

seat cushions. The

horizontal control adjusts

the seat cushion and

the vertical control adjusts

the seatback.

• Move the front of the seat control up or down to

adjust the front portion of the cushion.

• Move the rear of the seat control up or down to

adjust the rear portion of the cushion.

• Lift up or push down on the center of the seat

control to move the entire seat up or down.

• To move the seat forward or rearward, slide the

seat control forward or rearward.

• To recline the seatback, press the vertical control

rearward. To raise the seatback, press the vertical

control forward. See Reclining Seatbacks on

page 1-5 for more information.

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 symbol. Press the button

repeatedly to cycle through the temperature settings of

high, medium, low and off. The indicator lights above

the button will glow 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 button with the

words BACK ONLY. An indicator light on the switch will

glow 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

If your vehicle has a manual recliner, lift the lever

located on the outboard side of the seat and push

the seatback rearward to recline the seatback.

To return the seatback to the normal position, lift the

lever without pushing rearward on the seatback and the

seatback will move forward.

If your vehicle has power

seats, the power reclining

seatback control is

located on the outboard

side of the front seat

cushions. Press the control

rearward to recline the

seatback. Press the control

forward to raise the

seatback.

1-5

But do not have a seatback reclined if your vehicle is

moving.

{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.

1-6

Head Restraints

Pull the head restraint up

to raise it. Press the

release button, located at

the base of the head

restraint, and push

the head restraint down

to lower it.

Adjust the head restraint so that the top of the

restraint is closest to the top of the occupant’s head.

This position reduces the chance of a neck injury

in a crash.

1-7

1-10

row seatback, up to release the seatback and fold

the seatback forward.

seat lever, located on

the outboard side

of the seat and

indicated with the

number 2, to tumble

the seat forward.

Be sure to return the seat to the original position when

you are ﬁnished. Never use the third row as a seating

position while the second row is folded and tumbled.

1. Pull up on the handle located on the bottom of the

seat cushion to release the seat cushion.

2. Lift up the seat, and then pull it forward.

the seatback, to make a continuous surface to the

second row folded seat.

1-11

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.

1-12

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.

1-13

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

does not stop.
