How to Use This Manual

Many people read their owner’s manual from beginning to end when they first receive their new vehicle. If

you do this, it will help you learn about the features and controls for your vehicle. In this manual, you will find that pictures and words work together to explain things.

Index

A good place to look for what you need is the Index in back of the manual. It is an alphabetical list of what

is in the manual, and the page number where you will find it.

Safety Warnings and Symbols

You will find a number of safety cautions in this book. We use a box and the word CAUTION to tell you 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 don’t, you or others could be hurt.

You will also find a circle with a slash through it in this book. This safety symbol means “Don’t,” “Don’t do this” or “Don’t let this happen.”

iii

Vehicle Damage Warnings

Also, in this book you will find these notices:

Notice: These mean there is something that could damage your vehicle.

A notice will tell you about something that can damage your vehicle. Many times, this damage would not be covered by your warranty, and it could be costly.

But the notice will tell you 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.

You’ll also see warning labels on your vehicle. They use the same words, CAUTION or NOTICE.

Vehicle Symbols

Your vehicle has components and labels that use symbols instead of text. Symbols, used on your vehicle, 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

Front Seats

Power Seats

Your vehicle may have this feature. The power seat controls are located on the outboard side of the

front seat cushions. The horizontal control adjusts the seat cushion and

the vertical control adjusts the seatback.

Move the front of the horizontal seat control up or down to adjust the front portion of the cushion.

Move the rear of the seat control up or down to adjust the rear portion of the cushion.

Lift up or push down on the center of the seat control to move the entire seat up or down.

To move the seat forward or rearward, slide the seat control forward or rearward.

To recline the seatback, press the vertical control rearward. To raise the seatback, press the vertical control forward.

Power Lumbar

Your vehicle may have this feature. The seatback lumbar support can be adjusted by moving a control located on the outboard side of the seat cushions.

To increase or decrease support, hold the control forward or rearward. 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.

1-2

Heated Seats

Your vehicle may have heated front seats. The buttons used to control this feature are located on

the front door armrests. The engine must be running for the heated seat feature to work.

To heat only the seatback, press the button with the words BACK ONLY. An indicator light on the switch will glow to designate that only the seatback is being heated. Additional presses will cycle through the heat levels for the seatback only. Press the horizontal button again to heat the whole seat.

The feature will shut off automatically when the ignition is turned off.

To heat the entire seat, press the horizontal button with the heated seat symbol. Press the button repeatedly

to cycle through the temperature settings of high, medium, low and off. The indicator lights will glow 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.

1-3

Power Reclining Seatbacks

Your vehicle may have this feature. The vertical power seat control described earlier allows the seatback to recline. See Power Seats on page 1-2 for more information.

But don’t 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’t do their job when you’re reclined like this.

The shoulder belt can’t do its job. In a crash, you could go into it, receiving neck or other injuries.

The lap belt can’t 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.
