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

the front seat(s).

To increase support, press and hold the front of

the control. To decrease support, press and

If your vehicle has this

feature, the buttons are

located on the front

doors. The engine must

be running for the

heated seats 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. Indicator lights will come on to

designate the level of heat selected: three for

To heat only the seatback, press the vertical button

with the heated seatback symbol. An indicator light

on the seatback button will come on to designate

that only the seatback is being heated.

Additional presses of the seatback button will cycle

through the heat levels for the seatback only. Press

the horizontal button again to heat the whole seat.

The heated seats will be canceled after the ignition

is turned off. If you still want to use the heated seat

feature after you restart your vehicle, you will need

to press the heated seat button again.

Memory Seat and Mirrors

If your vehicle has this

feature, the controls for

the memory function

are located on the

driver’s door.

These buttons are used to program and recall

memory settings for the driver’s seat and both the

driver’s and passenger’s outside mirrors. The

settings for these features can be saved for up to

two drivers.

10

To store the memory settings, do the following:

1. While the vehicle is in PARK (P), adjust

the driver’s seat, including the seatback

recliner, lumbar, and side wing area, and

both outside mirrors to your preference.

2. Press and hold the 1 or 2 button of the memory

control for three seconds. A double chime will

sound to let you know that the position has

been stored.

To repeat the procedure for a second driver,

follow the preceding steps, but press the other

numbered memory control button.

Each time button 1 or 2 is pressed and released

while the vehicle is in PARK (P), a single chime will

sound and the memory position will be recalled.

To stop recall movement of the memory seat

feature at any time, press one of the memory

buttons or power seat controls.

Easy Exit Seat

The controls for this memory function are located

on the driver’s door.

B(Easy Exit Seat): This button is used to

program and recall the desired driver’s seat

position when exiting or entering the vehicle. The

seat position can be saved for up to two drivers.

To store the seat exit position, do the following:

1. Press and release the 1 or 2 button. The seat

will move to the stored memory position.

2. Adjust the seat to the desired exit position.

3. Press and hold the exit button of the memory

control for three seconds. A double chime will

sound to let you know that the position has

been stored for the selected button 1 or 2.

To repeat the procedure for a second driver,

follow the preceding steps, but press the

other numbered memory control button.

11

To use the seat exit position, do one of the

following:

• Press the exit button on the memory control,

or

• If this feature is activated in the DIC, removing

the key from the ignition will move the seat to

the exit position.

See “Easy Exit Seat” under DIC Vehicle

Customization on page 234 for more information

on activating this feature in the DIC.

Power Reclining Seatbacks

The front seats have power reclining seatbacks.

The control used to operate the seatbacks

are located on the outboard side of the seats.

• 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.

12

{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.

13

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. Push the

head restraint down to lower it.

Each front head restraint can also be tilted forward

to four positions by pulling on it. A click will

sound after each tilt position is reached. Pull the

head restraint forward, past the last position,

to release it to the upright position.

The rear seat head restraints are also adjustable

up and down, but they do not tilt.

14

Rear Seats

Heated Seats

If your vehicle has this

feature, the buttons

used to control

this feature are located

on the back of the

center console.

The engine must be

running for the heated

seat feature to work.

To heat the seat cushion, press the button to

cycle through the temperature settings of high and

low. Press the button a third time to turn the

feature off. An indicator light will glow for each heat

setting when the feature is operating.

The heated rear seats will shut off automatically

when the ignition is turned off.

60/40 Split Bench Seat

The 60/40 split bench seats can be folded to give

you more cargo space.

Folding the Seatbacks

The seatbacks are equipped with rearward folding

head restraints (SUV only). When the seatback

is being folded down, the head restraint will

automatically fold rearward.

1. Make sure that nothing is under or in front of

the seat.

2. Pull up on the strap

loop located at the

3. Pull the seatback forward and fold it down until

it is ﬂat.

If the seatback cannot fold ﬂat because it

interferes with the cushion, try moving the front

seat forward and/or bringing the front

seatback more upright.

4. Repeat the steps for the other half of the

60/40 split bench seat.

That could cause injury to the person

sitting there. Always push and pull on the

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.

16
