How to Use This Manual

Many people read the owner manual from

beginning to end when they ﬁrst receive their new

vehicle. If this is done, it can help you learn

about the features and controls for the vehicle.

Pictures and words work together in the

owner manual to explain things.

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.”

4

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

Memory Seat and Mirrors

Your vehicle may have the memory package.

The controls for this feature are located on the

driver’s door panel, and are used to program and

recall memory settings for the driver’s seat and

the outside mirrors.

To save your positions in memory, do the

following:

1. Adjust the driver’s seat, including the seatback

recliner and lumbar, and both outside mirrors

to your preferred position.

pressing button 2 for a second driver.

To recall your memory positions, the vehicle must

be in PARK (P). Press and release either

driving position. The seat and outside mirrors

will move to the position previously stored for the

identiﬁed driver. You will hear a single beep.

If you use the remote keyless entry transmitter to

feature is on, automatic seat and mirror movement

more information.

To stop recall movement of the memory feature at

memory buttons, or power mirror buttons.

If something has blocked the driver’s seat while

Then try recalling the memory position again

DIC Vehicle Customization on page 231 for

more information.

can be done using the DIC. You can select or

not select the following:

For programming information, see DIC Vehicle

Customization on page 231.

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.

14

If the seats have manual reclining seatbacks, the

lever used to operate them is located on the

outboard side of the seats.

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 the seats have power reclining seatbacks, the

controls used to operate them are located on

the outboard side of the seats.

• Tilt the top of the control rearward to recline

the seatback.

• Tilt the top of the control forward to raise the

seatback.

Recline, and Power Lumbar shown

{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 the 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.

17

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.

Center Seat

Your vehicle may have a front center seat. This

seat can be converted to a storage area by

lowering the seatback. See Center Flex Storage

Unit on page 152.

For information on safety belts for this position,

see Center Front Passenger Position on page 35.

18

Rear Seats

Rear Seat Pass-Through Door

Your vehicle has a pass-through door that provides

access to the trunk from the rear seats. See

“Rear Seat Pass-Through Door” under Trunk

on page 106.

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.

19

{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 to remind you and your

passengers to buckle your safety belts. See Safety

Belt Reminder Light on page 196 and Passenger

Safety Belt Reminder Light on page 197.

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 40 years of safety belts in

vehicles, the facts are clear. In most crashes

buckling up does matter... a lot!
