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’ll find that pictures and words work together to explain things quickly.

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 may be equipped with 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 in the Index:

“Engine Compartment Overview”

“Instrument Panel”

“Comfort Controls”

“Audio Systems”

Also see “Warning Lights and Gages” in the Index.

These are some examples of vehicle symbols you may find on your vehicle:

Seats and Seat Controls

This section tells you about the seats -- how to adjust them, and fold them up and down. It also tells you about reclining front seatbacks and head restraints.

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 front seatback forward or rearward by moving the control toward the front or toward the rear of the vehicle.

1-2

Power Lumbar Control

Memory Seat

Use the lumbar control, located on the outboard side of the seat, to increase or decrease lumbar support in an area of the lower seatback.

T o increase support, press and hold the front of the control. T o 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.

T o increase support, press and hold the top of the control. T o 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.

The controls for the memory function are located on the driver’s door trim panel.

These buttons are used to program and recall the memory settings for the driver’s seat and both the driver’s and the passenger’s outside mirrors and the radio station presets. The seat, mirror positions and radio station presets can be personalized for both driver 1 and driver 2. Driver 1 or driver 2 corresponds to the memory buttons labeled 1 and 2 on the driver’s door and the numbers, 1 or 2, embossed on the back of each keyless entry transmitter.

1-3

T o set your memory seat, mirrors and radio station presets, do the following:

1. Adjust the driver’s seat (including the recliner, lumbar and side wing area), both outside mirrors and the radio station presets to your preference. See “Mirrors” and “Radio” in the Index to learn how to adjust your mirrors and set the radio station presets.

2. Press and hold the 1 or 2 (for driver 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.

T o repeat the procedure for a second driver, follow the preceding steps, but press the other number of the memory control. The memory feature only works when the transmission is in PARK (P).

T o recall memory seat, mirror positions and radio station presets, make sure your vehicle is in PARK (P), then press the 1 or 2 button of the memory control. You will hear a single chime ring to let you know the memory position will be recalled

If you use the unlock button on the keyless entry transmitter to enter the vehicle, the preset driver’s seat, mirror positions and radio station presets will be recalled if programmed in the Driver Information Center (DIC). The numbers on the back of the transmitters, 1 or 2, correspond to the numbers on the memory control.

The preset driver’s seat, mirror positions and radio station presets will also be recalled when inserting the key into the ignition if programmed in the Driver Information Center (DIC). See “Seat Position Recall” in the Index for more information.

T o stop movement of the memory seat feature at any time, press one of the memory buttons or power seat controls.

1-4

Easy Exit Seat

This feature makes entering or leaving the driver’s seat easier.

(Exit): This button is used to program and recall

the desired driver’s seat exit/entry position. The seat position can be personalized for driver 1 and driver 2.

T o store the seat exit position for driver 1 or driver 2, do the following:

1. Select the desired driver number by pressing the 1 or 2 button. The seat will move to the last stored memory position.

2. Adjust the seat to the desired exit/entry position.

3. Press and hold the the exit button for three seconds. A double chime will sound to let you know the exit position has been stored for the identified driver (driver 1 or 2).

T o use the exit/entry feature, do one of the following:

Press the exit button on the memory control.

Or, if you have this feature enabled (active) in the DIC, then removing the key from the ignition will cause the seat to move to the exit/entry position. See “Driver Information Center” in the Index.

Heated Front Seats (If Equipped)

The buttons for the driver’s side heated seat are located on the driver’s side door panel. The buttons for the passenger’s side heated seat are located on the passenger’s side door panel.

The engine must be running for this feature to operate. T o heat the entire seat, press the horizontal button with

the heated seat symbol. Press the button to cycle through the temperature settings of high, medium and low and to turn the seat off. The indicator lights will glow to indicate the level of heat selected: three for high, two for medium and one for low.

The low setting warms the seatback and seat cushion until the seat temperature is near body temperature. The medium and high heat the seatback and seat cushion to a slightly higher temperature. You will be able to feel heat in about two minutes.

1-5

T o heat only the seatback, press the vertical button with the heated seatback symbol. An indicator light on the button 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 entire seat.

The heated front seats will shut off when the ignition is turned to LOCK.

Your vehicle also has rear heated seats. See the section “Rear Heated Seats” later in this section.

Reclining Front Seatbacks

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

But don’t have a seatback reclined if your vehicle is moving.

1-6

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.

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.

1-7

T o raise or lower a head restraint, pull up on the head restraint or push the head restraint down.

The head restraints tilt forward also. T o tilt a head restraint forward, grab the top of the restraint and pull it toward you until you hear a click. Let go of the head restraint and it will stay in that position. If you want the head restraint to tilt forward more, pull it forward again until you hear a click. You can pull it forward up to three times and on the fourth pull it will release to the initial, upright position.

Rear Seats

60/40 Split Bench Seat (Second Row)

The 60/40 split bench seat can be folded to give you more cargo space.

Folding the Seatbacks

CAUTION:

If the seatback isn’t locked, it could move forward in a sudden stop or crash. That could cause injury to the person sitting there. Always press rearward on the seatback to be sure it is locked.

1-8

T o fold the rear seat, do the following:

1. Insert the two safety belt buckles into the pockets on the driver’s side seatback and place the passenger’s side seat belt through the loop located near the armrest before folding the rear seat.

That way, the buckles will be out of the way when the seat is folded and will be available for passengers to use when the seat is returned to the passenger position. Also, 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. Then fold it forward.

3. Pull the seatback forward and fold it down until it is flat.

The rear seatbacks are equipped with rearward folding head restraints. When the seatback is being folded down, the head restraint will automatically fold rearward.

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.

Returning the Seats to an Upright Position

T o return the seat to the upright position, do the following:

1. Lift the seatback up and push it rearward all the way.

2. Lower the seat cushion until it latches into position.

3. Pull forward on the seatback and up on the seat cushion to make sure the seat is securely in place.

4. Return the head restraints to the upright position.

5. Check to see that the safety belt buckles on the driver’s side seatback are accessible to the outboard and center occupants and are not under the seat cushions.

1-9

Third Row Single Seat (If Equipped)

T o fold the seatback, do the following:

Folding the Seatback

CAUTION:

2. Unlatch the seat from the floor by pulling up on the lever labeled 2, located on the rear of the seat.

3. Lift the rear of the seat up off of the floor and push it forward until it locks into place. You will not be able to unlatch the seat from the floor unless the seatback is folded down.

The seat will now remain locked in the upright position.

1-11

Returning the Seat to an Upright Position

T o return the seat to an upright position, do the following:

1. Pull the lever labeled 3 toward you.

2. While still holding the lever 3 toward you, grasp the top of the seat and pull it toward you slightly.

3. Let go of lever 3 and pull the seat completely down.

4. Push down on the seat firmly. Try pulling it up to be sure it is locked into place.

4. Squeeze the release handle while pulling the seat out.

5. While holding the rear of the seat up, roll the seat out of the vehicle.

1-13

Replacing the Third Row Single Seat

CAUTION:

If the seatback isn’t locked, it could move forward in a sudden stop or crash. That could cause injury to the person sitting there. Always press rearward on the seatback to be sure it is locked.

CAUTION:

A seat that isn’t locked into place properly can move around in a collision or sudden stop. People in the vehicle could be injured. Be sure to lock the seat into place properly when installing it.

T o replace the third row single seat, do the following:

1. Open the liftgate.

2. While holding the rear of the seat up, slide the front wheels into the slots on the floor. The front latches should lock into place. If latches do not lock, try tilting the rear of the seat upwards.

3. Once the latches are engaged, let the seat drop into place. Pull the lever labeled 1 and pull the seatback up to return it to its upright position.

4. Push and pull on the seat to make sure it is locked into place. The seatback cannot be raised to the upright position unless the seat is secured to the floor.

1-15

Heated Rear Seats (Second Row) (If Equipped)

The controls are located on the back of the center console.

The ignition must be in RUN for this feature to operate. T o activate the heated seats, press the button to cycle

through the high, medium and low settings. T o turn off the heated seats, press the button a fourth time. An indicator light will illuminate for each heat setting any time the heated seats are operating.

The heated seats will be canceled after the ignition is turned to 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.

Safety Belts: They’re 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.

And it explains the air bag system.

CAUTION:

Don’t let anyone ride where he or she can’t wear a safety belt properly. If you are in a crash and you’re not wearing a safety belt, your injuries can be much worse. You can hit things inside the vehicle or be ejected from it. You can be seriously injured or killed. In the same crash, you might not be if you are buckled up. Always fasten your safety belt, and check that your passengers’ belts are fastened properly too.

1-16

CAUTION:

It is extremely dangerous to ride in a cargo area, inside or outside of a vehicle. In a collision, people riding in these areas are more likely to be seriously injured or killed. Do not allow people to ride in any area of your vehicle that is not equipped with seats and safety belts. Be sure everyone in your vehicle is in a seat and using a safety belt properly.

Your vehicle has a light that comes on as a reminder to buckle up. See “Safety Belt Reminder Light” in the Index.

In most states and in all Canadian provinces, the law says to wear safety belts. Here’s why: They work.

You never know if you’ll be in a crash. If you do have a crash, you don’t know if it will be a bad one.

A few crashes are mild, and some crashes can be so serious that even buckled up a person wouldn’t survive. But most crashes are in between. In many of them, people who buckle up can survive and sometimes walk away . Without belts they could have been badly hurt or killed.

After more than 30 years of safety belts in vehicles, the facts are clear. In most crashes buckling up does matter ... a lot!

1-17

Why Safety Belts Work

When you ride in or on anything, you go as fast as it goes.

T ake the simplest vehicle. Suppose it’s just a seat on wheels.

Put someone on it.

1-18

Get it up to speed. Then stop the vehicle. The rider doesn’t stop.

The person keeps going until stopped by something. In a real vehicle, it could be the windshield ...

1-19

or the instrument panel ... or the safety belts!

With safety belts, you slow down as the vehicle does. You get more time to stop. You stop over more distance, and your strongest bones take the forces. That’s why safety belts make such good sense.

Here Are Questions Many People Ask About Safety Belts

Won’t I be trapped in the vehicle after an

accident if I’m wearing a safety belt?

-- and the Answers

A: You could be -- whether you’re wearing a safety

belt or not. But you can unbuckle a safety belt, even if you’re upside down. And your chance of being conscious during and after an accident, so you can unbuckle and get out, is much greater if you are belted.

Q: If my vehicle has air bags, why should I have to

wear safety belts?

A: Air bags are in many vehicles today and will be in

most of them in the future. But they are supplemental systems only; so they work with safety belts system ever offered for sale has required the use of safety belts. Even if you’re in a vehicle that has air bags, you still have to buckle up to get the most protection. That’s true not only in frontal collisions, but especially in side and other collisions.

-- not instead of them. Every air bag

Q: If I’m a good driver, and I never drive far from

home, why should I wear safety belts?

A: You may be an excellent driver, but if you’re in an

accident and your passengers can be hurt. Being a good driver doesn’t protect you from things beyond your control, such as bad drivers.

Most accidents occur within 25 miles (40 km) of home. And the greatest number of serious injuries and deaths occur at speeds of less than 40 mph (65 km/h).

Safety belts are for everyone.

-- even one that isn’t your fault -- you

How to Wear Safety Belts Properly

Adults

This part is only for people of adult size. Be aware that there are special things to know about

safety belts and children. And there are different rules for smaller children and babies. If a child will be riding in your vehicle, see the part of this manual called “Children.” Follow those rules for everyone’s protection.

First, you’ll want to know which restraint systems your vehicle has.

We’ll start with the driver position.

Driver Position

This part describes the driver’s restraint system.

Lap-Shoulder Belt

The driver has a lap-shoulder belt. Here’s how to wear it properly.

1. Close and lock the door.

2. Adjust the seat so you can sit up straight. T o see how, see “Seats” in the Index.

3. Pick up the latch plate and pull the belt across you. Don’t let it get twisted.

The shoulder belt may lock if you pull the belt across you very quickly. If this happens, let the belt go back slightly to unlock it. Then pull the belt across you more slowly.

When the shoulder portion of the belt is pulled out all the way, it will lock. To permit the shoulder belt to move freely again, unbuckle the belt, let it retract all the way, and buckle up again.

1-22

4. Push the latch plate into the buckle until it clicks. Pull up on the latch plate to make sure it is secure.

If the belt isn’t long enough, see “Safety Belt Extender” at the end of this section.

Make sure the release button on the buckle is positioned so you would be able to unbuckle the safety belt quickly if you ever had to.

5. T o make the lap part tight, pull down on the buckle end of the belt as you pull up on the shoulder belt.

The lap part of the belt should be worn low and snug on the hips, just touching the thighs. In a crash, this applies force to the strong pelvic bones. And you’d be less likely to slide under the lap belt. If you slid under it, the belt would apply force at your abdomen. This could cause serious or even fatal injuries. The shoulder belt should go over the shoulder and across the chest. These parts of the body are best able to take belt restraining forces.

The safety belt locks if there’s a sudden stop or a crash, or if you pull the belt very quickly out of the retractor.

1-23

Q: What’s wrong with this?

A: The shoulder belt is too loose. It won’t give nearly

as much protection this way.

CAUTION:

You can be seriously hurt if your shoulder belt is too loose. In a crash, you would move forward too much, which could increase injury. The shoulder belt should fit against your body.
