Using this Manual Many people read the owner manual from beginning to end when they first receive their new vehicle to learn about the vehicle’s features and controls. Pictures and words work together 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. A box with the word CAUTION is used to tell about things that could hurt you or others if you were to ignore the warning.

{CAUTION:

These mean there is something that could hurt you or other people.

We tell you what the hazard is and what to do to help avoid or reduce the hazard. Please read these cautions. If you do not, you or others could be hurt.

A circle with a slash through it is a safety symbol which means “Do Not,” “Do Not do this” or “Do Not let this happen.”

iii

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.

Vehicle Damage Warnings You will also find notices in this manual. 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. The notice tells 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 which use the same words, CAUTION or NOTICE.

Front Seats

Manual Seats

{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.

To move a manual seat forward or rearward:

1. Lift the bar to unlock

the seat.

2. Slide the seat to the desired position and release the bar.

Try to move the seat with your body to be sure the seat is locked in place.

1-2

Power Seats

Power Lumbar

If the vehicle has power seats, the controls used to operate them are located on the outboard side of the seats.

If your vehicle has this feature, the control is located on the outboard side of the seat(s).

To adjust the seat, do any of the following: (cid:129) Move the seat forward or rearward by sliding the

control forward or rearward.

(cid:129) Raise or lower the front part of the seat cushion

by moving the front of the control up or down.

(cid:129) Raise or lower the rear part of the seat cushion

by moving the rear of the control up or down.

Press and hold the front of the control until you have the desired lumbar support. To decrease lumbar support, press and hold the rear of the control.

1-3

Heated Seats

If your vehicle has this feature, the controls are located on the outboard side of the front seats.

The ignition must be on for the heated seat feature to work. The seat will heat to the last setting if the ignition has been turned off and then turned back on. The passenger’s safety belt must be fastened for the heated seat feature to work on the passenger’s seat. 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.

This feature will heat the cushion and back of the seats. Press the top of the switch to turn the heat to the high setting. Press the bottom of the switch to turn the heat to the low setting. Put the switch in the center position to turn the heat off.

1-4

{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.

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: 1. Lift the recline lever and move the seatback to the desired position, then release the lever to lock the seatback in place.

2. Push and pull on the seatback to make sure

it is locked.

To return the seatback to an upright position: 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.

1-5

{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 because it will not be against your body. Instead, it will be in front of you. 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.

1-6

Head Restraints

Adjust the head restraint so that the top of the restraint is at the same height as the occupant’s head. This position reduces the chance of a neck injury in a crash.

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.

1-7

Rear Seats 60/40 Split Bench Seat The 60/40 split bench seats can be folded to give you more cargo space. Folding the Seatbacks To fold the rear seatback(s), do the following: 1. Make sure that nothing is on, under,

or in front of the seat.

2. Place your hand under

the front of the seat cushion and lift the cushion up while moving it forward.

There is a label below the seat cushion with instructions to aid in seat operation.

1-8

3. Pull the cushion forward until it rests in the footwell. 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.

4. Lift the latch on top of the seatback and pull the seatback forward. Fold the seatback down until it is nearly flat.

5. If the seatback will not fold nearly flat, try moving

the front seat forward and/or moving the front seatback more upright.

6. Repeat the steps for the other half of the 60/40 split

bench seat.

1-9

To return the seatback(s) to the upright position, do the following: 1. Lift the seatback up and push it rearward all the way. 2. Place your hand under the front of the seat cushion and lift the cushion while moving it rearward until it latches into position.

3. Pull forward on the seatback and push down on

the seat cushion to make sure the seat is securely in place.

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.

Returning the Seatbacks to an Upright Position

{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.
