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

• Climate Controls in Section 3

• Warning Lights, Gages, and Indicators 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 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:

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.

{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

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.
