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

• Audio System(s) in Section 3

• Engine Compartment Overview in Section 5

Section 1 Seats and Restraint Systems

1-1

Front Seats

Power Seats

The power seat controls are located on the outboard

edge of the front 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.

• Use the vertical control to recline the seatback.

See “Power Reclining Seatbacks” under Reclining

Seatbacks on page 1-4

Your seats may have a memory function which allows

seat settings to be saved and recalled. See Memory

Seat on page 2-62 for more information.

1-2

Power Lumbar

Your vehicle’s seats have power lumbar.

You can increase or

decrease lumbar support

in an area of the lower

seatback with this control,

located on the outboard

sides of the front seat(s).

To increase support, press and hold the front of the

control. To decrease support, press and hold the rear

of the control. Let go of the control when the lower

seatback reaches the desired level of support.

You can also reshape the side wing area of

the lower seatback for more lateral support.

To increase support, press and hold the top of the

control. To decrease support, press and hold the bottom

of the control. Let go of the control when the lower

seatback reaches the desired level of support.

Your vehicle may have a memory function which allows

seat settings to be saved and recalled. See Memory

Seat on page 2-62 for more information.

Heated Seats

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 be lit to designate the level of heat selected: three for

high, two for medium, and one for low.

1-3

To heat only the seatback, press the vertical button with

the heated seatback symbol. An indicator light on the

seatback button will be lit 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.

Reclining Seatbacks

Power Reclining Seatbacks

The front seats have power reclining seatbacks. Use the

vertical power seat control located on the outboard

side of the seat(s) to operate them.

• 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.

1-4

{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.

1-5

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.

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.

1-6

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 (SUV only) are equipped with rearward

folding head restraints. When the seatback is being

folded down, the head restraint will automatically

fold rearward.

To fold the rear seat, do the following:

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

the seat.

2. Pull up on the strap

loop located at the rear

of the seat cushion

and pull the seat

cushion up and fold

it forward.

Notice: Folding a rear seat with the safety belts

still fastened may cause damage to the seat or the

safety belts. Always unbuckle the safety belts

and return them to their normal stowed position

before folding a rear seat.

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.

bench seat.

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.
