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.”

iii

Vehicle Damage Warnings

Vehicle Symbols

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.

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

These are some examples of symbols that may be found on the vehicle:

Front Seats

Power Seats

Horizontal Control: You can adjust your vehicle’s front

seats with the horizontal control located on the outboard edge of each front seat.

Raise or lower the front of the seat by raising or lowering the forward edge of the control. Raise or lower the rear of the seat by raising or lowering the rear edge of the control.

Move the seat forward or rearward by moving the whole control toward the front or toward the rear of the vehicle.

Moving the whole control up or down raises or lowers the entire seat cushion.

Vertical Control: You can use the vertical control to adjust the angle of the seatback. Move the reclining seatback forward or rearward by moving the top of the control toward the front or toward the rear of the vehicle.

For information on the reclining seatbacks, see Reclining Seatbacks on page 1-6.

Your vehicle may have a memory function which allows seat settings to be saved and recalled. See Memory Seat on page 2-45 for more information.

1-3

Power Lumbar

Your vehicle’s seats may be equipped with 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 2-45 for more information.

1-4

Heated Seats

If your vehicle is equipped with 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 horizontalbuttonwith the heated seat and seatback symbol. Press thebuttonto cycle through the temperature settings of high, medium and low and to turn the heated seatoff.Indicator lights will be lit to designate the level of heat selected: three for high, two for medium, and one for low.

The low setting warms the seatback and 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.

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 front seats will shut off automatically when the ignition is turned off.

1-5

Reclining Seatbacks

The vertical power seat control described earlier allows the seatback to recline.

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 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.

1-6

Head Restraints

Adjust your head restraint so that the top of the restraint is closest to the top of your head. This position reduces the chance of a neck injury in a crash.

The head restraints tilt forward and rearward also. To adjust the tilt for either of the front head restraints,

pull it toward you until you hear a click. There are four positions available: initial position, ﬁrst click, second click and third click. Each position will click into place. After the third position (three clicks) is reached, pulling the head restraint farther will release it back to the upright position.

Pull ﬁrmly on the top of the head restraint to position it to your liking.

The rear seat head restraints in your vehicle are adjustable up and down. Move the head restraint so that the top of the restraint is closest to the top of your head. This position reduces the chance of a neck injury in a crash.
