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

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 seat cushion to

unlock the seat.

Slide the seat to the desired position and release the

bar. Try to move the seat back and forth to make sure it

is locked in place.

1-3

Six-Way Power Seats

If your vehicle has power seats, the controls are located

on the outboard sides of the seat cushions.

• To move the entire seat forward or rearward, move

the control forward or rearward.

• To raise or lower the entire seat, move the control

up or down.

• To raise or lower the front of the seat, move the

front of the control up or down.

• To raise or lower the rear of the seat, move the

rear of the control up or down.

Power Lumbar

Your vehicle may have power lumbar. The control is

located on the outboard side of the driver’s seat cushion.

Press the front of the control to increase lumbar

support. Press the rear of the control to decrease

lumbar support.

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.

1-4

Heated Seats

If your vehicle has this

feature, the buttons are

located on the climate

control panel.

Press the button once to activate a high heat setting.

Both indicator lights above the button will come on.

Press the button again to select a lower temperature

setting. Only one indicator light will come on. Press the

button a third time to turn the heat off.

This feature only works when the ignition is on.

Reclining Seatbacks

Lift the lever located on the outboard side of the seat to

release the seatback, then move the seatback to the

desired position. Release the lever to lock the seatback

in place.

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 can not do their

job when you are reclined like this.

The shoulder belt can not 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 can not 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

Adjust the head restraint so that the top of the restraint

is closest to the top of the occupant’s head in each

front seat. This position reduces the chance of a neck

injury in a crash. Push the release button, located under

the head restraint, to lower the head restraint.

Center Seat

Your vehicle may have a front center seat. This seat

can be converted to a storage area by lowering

the armrest. See Center Console Storage Area on

page 2-41.

For information on safety belts for this position, see

Center Front Passenger Position on page 1-24.

1-7

Rear Seats

Split Folding Rear Seat

If your vehicle has this feature, both sides of the rear

seatback can be folded down in the vehicle. Make sure

the front seat is not reclined. If it is, the rear seatback

may not fold down all the way.

To lower the rear seatback, follow these steps:

1. Disconnect the rear center lap-shoulder belt latch, if

equipped, by using a pointed object to press the

release button.

2. Pull forward on the

seatback tab located

on the outboard side

of the rear seat

cushion to fold the

seatback down.

This gives direct access to the trunk.

{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

press rearward on the seatback to be sure it

is locked.

1-8

{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 raise the rear seatback, follow these steps:

1. Raise the seatback up and make sure it latches.

Push and pull on the seatback to be sure it is

locked in position.

2. Reconnect the center

safety belt latch plate

to the buckle.

Make sure the safety belt label is pointing to the release

button, and that both are facing the front of the

vehicle. Make sure the belt is not twisted. Push and pull

on the latch plate to be sure it is secure.

When the seat is not in use, the seatback should be

kept in the upright, locked position.

1-9

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 can not

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 3-32.

1-10

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.

1-11

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

does not stop.

1-12

The person keeps going until stopped by something. In

a real vehicle, it could be the windshield...

or the instrument panel...

1-13

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.
