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.

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.

vii

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.”

Vehicle Damage Warnings

Also, in this book you will find these notices:

NOTICE:

These mean there is something that could damage your vehicle.

In the notice area, we 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:

Seats and Seat Controls

This section tells you about the power seats -- how to adjust them, and also about the reclining front seatbacks, memory seats, lumbar adjustments and heated seats.

Power Seats

The power seat controls are located on the outboard side of the front seat cushions.

Move the front of the 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.

T o move the seat forward or rearward, slide the seat control forward or rearward.

T o recline the seatback, press the vertical control rearward. T o raise the seatback, press the vertical control forward.

Four-Way Power Lumbar Control

The driver’s and passenger’s seatback lumbar support can be adjusted four ways by moving a single control located on the outboard side of the seat cushions.

T o increase or decrease support, hold the control forward or rearward. T o move the lumbar up or down, hold the control up or down.

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

Memory Seat (If Equipped)

If your vehicle has this feature the controls are located on the driver’s door, and are used to program and recall memory settings for the driver’s seating and outside mirror positions.

Adjust the driver’s seat (including the seatback recliner and lumbar) and both of the outside mirrors to the desired position. Then press and hold button 1 (for driver 1) for three seconds. A chime will sound to let you know that the position has been stored.

A second mirror and seating position can be programmed by repeating the procedure with a second driver and pressing button 2 for three seconds. Each time button 1 or 2 is pressed and released while the vehicle is in PARK (P), the memory position will be recalled. Each time a memory button is pressed, a single chime will sound.

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

The seat and mirror positions can also be recalled by placing the key in the ignition if programmed to do so through the Driver Information Center (DIC).

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

T wo personalized exit positions can be set by first recalling the driver’s position (by pressing 1 or 2), then positioning the seat in the desired exit position for that driver. Then press and hold the button with the exit symbol for three seconds. A chime will sound to let you know that the position has been stored. With the vehicle in PARK (P), the exit position for that driver can be recalled by pressing the exit button. The mirrors, power lumbar and recline positions will not be stored or recalled for the exit positions.

1-3

Programming for automatic seat and mirror movement can be done through the Driver Information Center (DIC). You can choose to either select or not select automatic seat and mirror movement by using the remote keyless entry transmitter, by placing your key in the ignition, or when exiting the vehicle. For programming information, see “Vehicle Programming and Personalization Features” in the Index.

Heated Front Seats (Option)

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.

The horizontal button with the heated seat symbol is used to control the temperature settings high, medium and low. Press the button to cycle through the temperature settings and to turn the heated seat off. An indicator light will glow beside the temperature selected. 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.

T o heat only the seatback, press the vertical button with the heated seatback symbol. Press the vertical button again to heat the whole seat.

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

1-4

Power Reclining Front Seatback

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

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.

1-5

Head Restraints

Rear Seats

Your vehicle has a folding rear seat which lets you fold the seatbacks down for more cargo space.

Slide the head restraint up or down 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.

On some models, the head restraints tilt forward and rearward also.

The head restraints lock into place when raised. T o release the head restraint and lower it, press the tab located on the top of the seatback.

1-6

Pull up on the tab located where the seat cushion meets the seatback to fold the seat cushion up and out of the way . This will allow the seatback to fold flat and increase the cargo area.

The rear seatback handles are located on the outboard side of the rear seatbacks.

Pull the seatback toward you as you lift up on the handle. The head restraint will automatically fold out of the way when the seatback is folded down.

T o raise the seatbacks, lift up the seatbacks and push on them until they lock into the upright position. Push and pull on the seatbacks to make sure that they are latched securely. Then fold the bottom seat cushion back into place.

T o return the head restraint to the upright position, reach behind the seat and pull the restraint up until it locks into place. Push and pull on the head restraint to make sure that it is latched securely.

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.

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.

1-8

In most states and 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!

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.

1-9

Put someone on it. Get it up to speed. Then stop the vehicle. The rider

doesn’t stop.

1-10

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

or the instrument panel ...

1-11

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

1-12

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 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 and

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.

1-13

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.

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.

1-14

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 crash, or if you pull the belt very quickly out of the retractor.

1-15

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.

1-16

Q: What’s wrong with this?

A: The belt is buckled in the wrong place.

CAUTION:

You can be seriously injured if your belt is buckled in the wrong place like this. In a crash, the belt would go up over your abdomen. The belt forces would be there, not at the pelvic bones. This could cause serious internal injuries. Always buckle your belt into the buckle nearest you.

1-17

Q: What’s wrong with this?

A: The shoulder belt is worn under the arm. It should

be worn over the shoulder at all times.

CAUTION:

You can be seriously injured if you wear the shoulder belt under your arm. In a crash, your body would move too far forward, which would increase the chance of head and neck injury. Also, the belt would apply too much force to the ribs, which aren’t as strong as shoulder bones. You could also severely injure internal organs like your liver or spleen.
