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.

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.

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

You can adjust the front seats with the controls located on the side of the seat, next to the door.

You can use the round center knob to move the seat to where you want it. T o do this, move the knob up. To lower the seat, move the knob down. T o move the seat forward or rearward, move the knob toward the front of the vehicle or toward the rear.

You can also raise and lower the front and rear of the seat. T o raise or lower the front of the seat, move the front lever up or down. T o raise or lower the rear of the seat, move the rear lever up or down.

1-2

Power Lumbar Adjustment

Heated Front Seats

Your vehicle has a power lumbar adjuster located at the front of the control panel on the left side of the seat. You can increase or decrease lumbar support in an area of the lower seatback.

T o increase support, press and hold the front of the rocker switch. Let go of the switch when the lower seatback reaches the desired level of support.

T o decrease support, press and hold the rear of the rocker switch. Let go of the switch when the lower seatback reaches the desired level of support.

The control for the driver’s side heated seat is located on the left side of the seat. The control for the right front passenger is located on the right side of the passenger seat. Move the switch forward to MED or HIGH temperature to turn on the heating elements in the seat. The right front passenger’s safety belt must be buckled before the heating elements in that seat will operate. T o turn the heated seats off, move the switch rearward to OFF. For information on heated rear seats, see “Heated Rear Seats” in the Index.

1-3

Reclining Front Seatbacks

T o adjust the seatback, move the lever rearward.

Release the lever to lock the seatback where you want it. Move the lever again rearward and the seatback will go to an upright position.

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

1-4

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 because it won’t 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 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

Slide the head restraint up or down so that the top of the restraint is closest to the top of your ears. This position reduces the chance of a neck injury in a crash.

The head restraints tilt forward and rearward also. Pull firmly on the top of the head restraint to position it

to your liking.

Rear Seats

CAUTION:

If a head restraint is not installed on the seatback or stored in the vehicle properly, it could be thrown about the vehicle in a crash or sudden maneuver. People in the vehicle could be injured. Remove the head restraints only when you need to fold the seat, and be sure that the head restraints are stored securely in the appropriate holes at the rear of the lower seat cushion. When the seat is returned to the passenger position, be sure the head restraints are installed properly.

1-5

Folding the Rear Seat

Your vehicle has a 60/40 rear seat. Either side may be folded down to give you more cargo space.

Before folding, place the latch portion of the center safety belt in the center armrest. That way, the center safety belt will be out of the way when the seat is folded and also will be easily 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. When the seat is folded, it will lay flat on the floor.

T o fold the seat, pull up on the strap loop at the rear of the seat cushion.

Then, pull the seat cushion up and fold it forward.

Fold the seatback forward enough to allow removal of the head restraints. Push and hold the release buttons at the bottom of each head restraint height post and slide the head restraint out of the height

-adjust tubes.

Set the head restraints aside for now. You will stow them in their proper position after you are done folding the seat.

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

-adjust

1-6

Then, store the head restraints by sliding them into the rear of the seat cushion. Make sure the posts go in all the way.

T o return the seat to the passenger position, use the following procedure:

1. Remove the head restraints by sliding them out of the seat cushion.

2. Lift the seatback up enough to install the head restraints.

3. Push the seatback rearward all the way.

4. Lower the seat cushion until it latches in position.

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

If the latch plate portion of the center safety belt was put in the center armrest when the seat was folded, take the latch plate portion out and place it on the seat. That way, the center position safety belt will be available for the center rear seat passenger to use.

1-7

Heated Rear Seats

The controls for the heated rear seats are located on the rear of the center floor console, below the rear seat audio controls.

Press the top of the switch to HI or the bottom of the switch to LO to turn on the heating elements in the outside rear seat positions. The text HI or LO on the switch will illuminate to indicate that the heated seat elements are operating. The switch on the left side operates the driver’s seat and the switch on the right side operates the passenger’s sent. The rear seat outside passenger’s safety belt must be attached before the heating element in that seat will operate. T o turn the heated seats off, move the switch to the center. For more information on heated front seats, see “Heated Front Seats” in the Index.

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.

1-8

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 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!

1-9

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.

1-10

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 ...

1-11

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.

1-12

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.

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 (to see how, see “Seats” in the Index) so you can sit up straight.

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

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.

1-15

Shoulder Belt Height Adjuster

Before you begin to drive, move the shoulder belt adjuster to the height that is right for you.

T o move it down, push in at the word PRESS and move the height adjuster to the desired position. You can move the adjuster up just by pushing up on the shoulder belt guide. After you move the adjuster to where you want it, try to move it down without pushing in to make sure it has locked into position.

Adjust the height so that the shoulder portion of the belt is centered on your shoulder. The belt should be away from your face and neck, but not falling off your shoulder.

1-16

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.

1-17

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.

1-18

Q: What’s wrong with this?

A: The belt is over an armrest.

CAUTION:

You can be seriously injured if your belt goes over an armrest like this. The belt would be much too high. In a crash, you can slide under the belt. The belt force would then be applied at the abdomen, not at the pelvic bones, and that could cause serious or fatal injuries. Be sure the belt goes under the armrests.

1-19

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.

1-20

Q: What’s wrong with this?

A: The belt is twisted across the body.

CAUTION:

You can be seriously injured by a twisted belt. In a crash, you wouldn’t have the full width of the belt to spread impact forces. If a belt is twisted, make it straight so it can work properly, or ask your dealer to fix it.

1-21

T o unlatch the belt, just push the button on the buckle. The belt should go back out of the way.

Before you close the door, be sure the belt is out of the way . If you slam the door on it, you can damage both the belt and your vehicle.

Safety Belt Use During Pregnancy

Safety belts work for everyone, including pregnant women. Like all occupants, they are more likely to be seriously injured if they don’t wear safety belts.

A pregnant woman should wear a lap-shoulder belt, and the lap portion should be worn as low as possible, below the rounding, throughout the pregnancy.

1-22

The best way to protect the fetus is to protect the mother. When a safety belt is worn properly, it’s more likely that the fetus won’t be hurt in a crash. For pregnant women, as for anyone, the key to making safety belts effective is wearing them properly.

Here are the most important things to know about the air bag system:

CAUTION:

Right Front Passenger Position

To learn how to wear the right front passenger’s safety belt properly, see “Driver Position” earlier in this section.

The right front passenger’s safety belt works the same way as the driver’s safety belt If you ever pull the lap portion of the belt out all the way , you will engage the child restraint locking feature. If this happens, just let the belt go back all the way and start again.

-- except for one thing.

Air Bag System

This part explains the air bag system. Your vehicle has air bags

and another air bag for the right front passenger. Frontal air bags are designed to help reduce the risk of

injury from the force of an inflating air bag. But these air bags must inflate very quickly to do their job and comply with federal regulations.

-- one air bag for the driver

You can be severely injured or killed in a crash if you aren’t wearing your safety belt have air bags. Wearing your safety belt during a crash helps reduce your chance of hitting things inside the vehicle or being ejected from it. Air bags are “supplemental restraints” to the safety belts. All air bags are designed to work with safety belts, but don’t replace them. Air bags are designed to work only in moderate to severe crashes where the front of your vehicle hits something. They aren’t designed to inflate at all in rollover, rear, side or low crashes. And, for unrestrained occupants, air bags may provide less protection in frontal crashes than more forceful air bags have provided in the past. Everyone in your vehicle should wear a safety belt properly not there’s an air bag for that person.

-speed frontal

-- even if you

-- whether or

1-23

CAUTION:

Air bags inflate with great force, faster than the blink of an eye. If you’re too close to an inflating air bag, as you would be if you were leaning forward, it could seriously injure you. Safety belts help keep you in position before and during a crash. Always wear your safety belt, even with air bags. The driver should sit as far back as possible while still maintaining control of the vehicle.

1-24

Anyone who is up against, or very close to, any air bag when it inflates can be seriously injured or killed. Air bags plus lap the best protection for adults, but not for young children and infants. Neither the vehicle’s safety belt system nor its air bag system is designed for them. Young children and infants need the protection that a child restraint system can provide. Always secure children properly in your vehicle. To read how, see the part of this manual called “Children.”

-shoulder belts offer

There is an air bag readiness light on the instrument panel, which shows AIR BAG.

The system checks the air bag electrical system for malfunctions. The light tells you if there is an electrical problem. See “Air Bag Readiness Light” in the Index for more information.

How the Air Bag System Works

Where are the air bags?

The driver’s air bag is in the middle of the steering wheel.

1-25

The right front passenger’s air bag is in the instrument panel on the passenger’s side.

CAUTION:

If something is between an occupant and an air bag, the bag might not inflate properly or it might force the object into that person. The path of an inflating air bag must be kept clear. Don’t put anything between an occupant and an air bag, and don’t attach or put anything on the steering wheel hub or on or near any other air bag covering.

1-26

When should an air bag inflate?

An air bag is designed to inflate in a moderate to severe frontal or near only if the impact speed is above the system’s designed “threshold level.” If your vehicle goes straight into a wall that doesn’t move or deform, the threshold level is about 9 to 16 mph (14 to 26 km/h). The threshold level can vary, however, with specific vehicle design, so that it can be somewhat above or below this range. If your vehicle strikes something that will move or deform, such as a parked car, the threshold level will be higher. The air bag is not designed to inflate in rollovers, side impacts or rear impacts, because inflation would not help the occupant.

In any particular crash, no one can say whether an air bag should have inflated simply because of the damage to a vehicle or because of what the repair costs were. Inflation is determined by the angle of the impact and how quickly the vehicle slows down in frontal or near

-frontal impacts.

The air bag system is designed to work properly under a wide range of conditions, including off Observe safe driving speeds, especially on rough terrain. As always, wear your safety belt. See “Off-Road Driving” in the Index for more tips on off

-frontal crash. The air bag will inflate

-road usage.

-road driving.

What makes an air bag inflate?

In an impact of sufficient severity, the air bag sensing system detects that the vehicle is in a crash. The sensing system triggers a release of gas from the inflator, which inflates the air bag. The inflator, air bag and related hardware are all part of the air bag modules inside the steering wheel and in the instrument panel in front of the right front passenger.

How does an air bag restrain?

In moderate to severe frontal or near even belted occupants can contact the steering wheel or the instrument panel. Air bags supplement the protection provided by safety belts. Air bags distribute the force of the impact more evenly over the occupant’s upper body, stopping the occupant more gradually. But air bags would not help you in many types of collisions, including rollovers, rear impacts and side impacts, primarily because an occupant’s motion is not toward those air bags. Air bags should never be regarded as anything more than a supplement to safety belts, and then only in moderate to severe frontal or near

-frontal collisions.

-frontal collisions,

1-27

What will you see after an air bag inflates?

After an air bag inflates, it quickly deflates, so quickly that some people may not even realize the air bag inflated. Some components of the air bag module wheel hub for the driver’s air bag, or the instrument panel for the right front passenger’s bag -- will be hot for a short time. The parts of the bag that come into contact with you may be warm, but not too hot to touch. There will be some smoke and dust coming from vents in the deflated air bags. Air bag inflation doesn’t prevent the driver from seeing or from being able to steer the vehicle, nor does it stop people from leaving the vehicle.

-- the steering

CAUTION:

When an air bag inflates, there is dust in the air. This dust could cause breathing problems for people with a history of asthma or other breathing trouble. To avoid this, everyone in the vehicle should get out as soon as it is safe to do so. If you have breathing problems but can’t get out of the vehicle after an air bag inflates, then get fresh air by opening a window or door.

In many crashes severe enough to inflate an air bag, windshields are broken by vehicle deformation. Additional windshield breakage may also occur from the right front passenger air bag.

Air bags are designed to inflate only once. After they inflate, you’ll need some new parts for your air bag system. If you don’t get them, the air bag system won’t be there to help protect you in another crash. A new system will include air bag modules and possibly other parts. The service manual for your vehicle covers the need to replace other parts.

Your vehicle is equipped with a crash sensing and diagnostic module, which records information about the air bag system. The module records information about the readiness of the system, when the system commands air bag inflation and driver’s safety belt usage at deployment. Some modules also record speed, engine rpm, brake and throttle data.

Let only qualified technicians work on your air bag system. Improper service can mean that your air bag system won’t work properly. See your dealer for service.

1-28

NOTICE:

If you damage the covering for the driver’s or the right front passenger’s air bag, the bag may not work properly. You may have to replace the air bag module in the steering wheel or both the air bag module and the instrument panel for the right front passenger’s air bag. Do not open or break the air bag coverings.

Servicing Your Air Bag-Equipped Vehicle

Air bags affect how your vehicle should be serviced. There are parts of the air bag system in several places around your vehicle. You don’t want the system to inflate while someone is working on your vehicle. Your dealer and the service manual have information about servicing your vehicle and the air bag system. T o purchase a service manual, see “Service and Owner Publications” in the Index.

If your vehicle ever gets into a lot of water -- such as water up to the carpeting or higher your vehicle and soaks the carpet, the air bag controller can be soaked and ruined. If this ever happens, and then you start your vehicle, the damage could make the air bags inflate, even if there’s no crash. You would have to replace the air bags as well as the sensors and related parts. If your vehicle is ever in a flood, or if it’s exposed to water that soaks the carpet, you can avoid needless repair costs by turning off the vehicle immediately and disconnecting the battery cables. Don’t let anyone start the vehicle under any circumstances. See your dealer for service.

-- or if water enters

CAUTION:

For up to 10 minutes after the ignition key is turned off and the battery is disconnected, an air bag can still inflate during improper service. You can be injured if you are close to an air bag when it inflates. Avoid yellow connectors. They are probably part of the air bag system. Be sure to follow proper service procedures, and make sure the person performing work for you is qualified to do so.

The air bag system does not need regular maintenance.

1-29

Adding Equipment to Your Air Bag-Equipped Vehicle

Q: If I add a push bumper or a bicycle rack to the

front of my vehicle, will it keep the air bags from working properly?

A: As long as the push bumper or bicycle rack is

attached to your vehicle so that the vehicle’s basic structure isn’t changed, it’s not likely to keep the air bags from working properly in a crash.

Q: Is there anything I might add to the front of the

vehicle that could keep the air bags from working properly?

A: Yes. If you add things that change your vehicle’s

frame, bumper system, front end sheet metal or height, they may keep the air bag system from working properly. Also, the air bag system may not work properly if you relocate any of the air bag sensors. If you have any questions about this, you should contact Customer Assistance before you modify your vehicle.

It’s very important for rear seat passengers to buckle up! Accident statistics show that unbelted people in the rear seat are hurt more often in crashes than those who are wearing safety belts.

Rear passengers who aren’t safety belted can be thrown out of the vehicle in a crash. And they can strike others in the vehicle who are wearing safety belts.

Rear Seat Outside Passenger Positions

1-30

Lap-Shoulder Belt

The positions next to the windows have lap belts. Here’s how to wear one properly.

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

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

-shoulder

When the shoulder belt is pulled out all the way, it will lock. If it does, let it go back all the way and start again.

If the belt is not 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.

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

1-31

The safety belt locks if there’s a sudden stop or a crash. Each position next to the windows has a shoulder belt

height adjuster. Move the shoulder belt height adjuster to the height that is right for you.

1-32

To move the height adjuster down, push in at the word PRESS and move the height adjuster to the desired position. You can move the adjuster up just by pushing up on the shoulder belt guide. After you move the adjuster to where you want it, try to move it down without pushing in to make sure it has locked into position.

Adjust the height so that the shoulder portion of the belt is centered on your shoulder. The belt should be away from your face and neck, but not falling off your shoulder.

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.

1-33

T o unlatch the belt, just push the button on the buckle.

Rear Safety Belt Comfort Guides for Children and Small Adults

Rear shoulder belt comfort guides will provide added safety belt comfort for children who have outgrown child restraints and for small adults. When installed on a shoulder belt, the comfort guide pulls the belt away from the neck and head.

There is one guide for each outside passenger position in the rear seat. T o provide added safety belt comfort for children who have outgrown child restraints and for smaller adults, the comfort guides may be installed on the shoulder belts. Here’s how to install a comfort guide and use the safety belt:

1-34

1. Remove the guide from its storage clip on the side of the seatback.

2. Slide the guide under and past the belt. The elastic cord must be under the belt. Then, place the guide over the belt, and insert the two edges of the belt into the slots of the guide.

1-35

3. Be sure that the belt is not twisted and it lies flat. The elastic cord must be under the belt and the guide on top.

1-36

4. Buckle, position and release the safety belt as described in “Rear Seat Outside Passenger Positions” earlier in this section. Make sure that the shoulder belt crosses the shoulder.

T o remove and store the comfort guides, squeeze the belt edges together so that you can take them out from the guides. Slide the guide onto the storage clip.

Make sure you remove the comfort guide from the belt before you fold a rear seat down.

Center Passenger Position

Lap Belt

When you sit in the center seating position, you have a lap safety belt, which has no retractor. To make the belt longer, tilt the latch plate and pull it along the belt.

1-37

T o make the belt shorter, pull its free end as shown until the belt is snug.

Buckle, position and release it the same way as the lap part of a lap 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.

Children

Everyone in a vehicle needs protection! That includes infants and all children smaller than adult size. Neither the distance traveled nor the age and size of the traveler changes the need, for everyone, to use safety restraints. In fact, the law in every state in the United States and in every Canadian province says children up to some age must be restrained while in a vehicle.

Smaller Children and Babies

CAUTION:

Children who are up against, or very close to, any air bag when it inflates can be seriously injured or killed. Air bags plus lap the best protection for adults, but not for young children and infants. Neither the vehicle’s safety belt system nor its air bag system is designed for them. Young children and infants need the protection that a child restraint system can provide. Always secure children properly in your vehicle.

-shoulder belts offer

1-38

CAUTION:

Smaller children and babies should always be restrained in a child or infant restraint. The instructions for the restraint will say whether it is the right type and size for your child. A very young child’s hip bones are so small that a regular belt might not stay low on the hips, as it should. Instead, the belt will likely be over the child’s abdomen. In a crash, the belt would apply force right on the child’s abdomen, which could cause serious or fatal injuries. So, be sure that any child small enough for one is always properly restrained in a child or infant restraint.

Infants need complete support, including support for the head and neck. This is necessary because an infant’s neck is weak and its head weighs so much compared with the rest of its body. In a frontal crash, an infant in a rear

-facing restraint settles into the restraint, so the crash

forces can be distributed across the strongest part of the infant’s body, the back and shoulders. A baby should be secured in an appropriate infant restraint. This is so important that many hospitals today won’t release a newborn infant to its parents unless there is an infant restraint available for the baby’s first trip in a motor vehicle.

1-39

CAUTION:

Never hold a baby in your arms while riding in a vehicle. A baby doesn’t weigh much crash. During a crash a baby will become so heavy you can’t hold it. For example, in a crash

Child Restraints

Every time infants and young children ride in vehicles, they should have protection provided by appropriate restraints.

Q: What are the different types of add-on

child restraints?

A: Add-on child restraints are available in four basic

types. When selecting a child restraint, take into consideration not only the child’s weight and size, but also whether or not the restraint will be compatible with the motor vehicle in which it will be used.

An infant car bed (A) is a special bed made for use in a motor vehicle. It’s an infant restraint system designed to restrain or position a child on a continuous flat surface. With an infant car bed, make sure that the infant’s head rests toward the center of the vehicle.

1-41

A rear-facing infant restraint (B) positions an infant to face the rear of the vehicle. Rear restraints are designed for infants of up to about 20 lbs. (9 kg) and about one year of age. This type of restraint faces the rear so that the infant’s head, neck and body can have the support they need in a frontal crash. Some infant seats come in two parts

-- the base stays secured in the vehicle and

the seat part is removable.

-facing infant

1-42

A forward-facing child restraint (C-E) positions a child upright to face forward in the vehicle. These forward help protect children who are from 20 to 40 lbs. (9 to 18 kg) and about 26 to 40 inches (66 to 102 cm) in height, or up to around four years of age. One type, a convertible restraint, is designed to be used either as a rear seat or a forward

-facing restraints are designed to

1-43

A booster seat (F) is designed for children who are about 40 to 60 lbs., or even up to 80 lbs. (18 to 27 kg, or even up to 36 kg), and about four to eight years of age. A booster seat is designed to improve the fit of the vehicle’s safety belt system. Booster seats with shields use lap

When choosing a child restraint, be sure the child restraint is designed to be used in a vehicle. If it is, it will have a label saying that it meets federal motor vehicle safety standards.

Then follow the instructions for the restraint. You may find these instructions on the restraint itself or in a booklet, or both. These restraints use the belt system in your vehicle, but the child also has to be secured within the restraint to help reduce the chance of personal injury. The instructions that come with the infant or child restraint will show you how to do that. Both the owner’s manual and the child restraint instructions are important, so if either one of these is not available, obtain a replacement copy from the manufacturer.

Where to Put the Restraint

Accident statistics show that children are safer if they are restrained in the rear rather than the front seat. We at General Motors therefore recommend that you put your child restraint in a rear seat. Never put a rear child restraint in the right front passenger seat. Here’s why:

-facing

1-44

CAUTION:

A child in a rear-facing child restraint can be seriously injured or killed if the right front passenger’s air bag inflates. This is because the back of the rear very close to the inflating air bag. Always secure a rear

-facing child restraint in a rear seat.

You may secure a forward-facing child restraint in the right front seat, but before you do, always move the front passenger seat as far back as it will go. It’s better to secure the child restraint in a rear seat.

Wherever you install it, be sure to secure the child restraint properly.

Keep in mind that an unsecured child restraint can move around in a collision or sudden stop and injure people in the vehicle. Be sure to properly secure any child restraint in your vehicle

-facing child restraint would be

-- even when no child is in it.

Top Strap

In Canada, the law requires that forward-facing child restraints have a top strap, and that the strap be anchored. In the United States, some child restraints also have a top strap. If your child restraint has a top strap, it should be anchored.

Anchor brackets for the rear outside seat positions are located on the floor in the cargo area.

1-45

CAUTION:

Routing the top strap for a child restraint over or under the cargo security shade could cause the shade to come loose and even break. If this happens, the shade could be thrown about the vehicle in a collision or sudden maneuver. You or others could be injured. When anchoring a top strap to a cargo tiedown, be sure to remove the cargo security shade from your vehicle. See “Cargo Security Shade” in the Index.

Don’t use the front set of tie-down brackets. Anchor the top strap to the rearmost bracket on the same side of the vehicle as the child restraint. If you need to have an anchor bracket installed for the center rear seat, you can ask your dealer to put it in for you. This work will be done for you free of charge. If you want to install the anchor yourself, your dealer can tell you how to do it.

1-46

Securing a Child Restraint in a Rear Outside Seat Position

You’ll be using the lap-shoulder belt. See the earlier part about the top strap if the child restraint has one. Be sure to follow the instructions that came with the child restraint. Secure the child in the child restraint when and as the instructions say.

1. Put the restraint on the seat.

2. Pick up the latch plate, and run the lap and shoulder portions of the vehicle’s safety belt through or around the restraint. The child restraint instructions will show you how.

If the shoulder belt goes in front of the child’s face or neck, put it behind the child restraint.

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

1-47

4. Pull the rest of the shoulder belt all the way out of the retractor to set the lock.

1-48

5. T o tighten the belt, feed the shoulder belt back into the retractor while you push down on the child restraint. If you’re using a forward restraint, you may find it helpful to use your knee to push down on the child restraint as you tighten the belt.

6. Push and pull the child restraint in different directions to be sure it is secure.

-facing child

T o remove the child restraint, just unbuckle the vehicle’s safety belt and let it go back all the way. The safety belt will move freely again and be ready to work for an adult or larger child passenger.

Securing a Child Restraint in the Center Rear Seat Position

You’ll be using the lap belt. Be sure to follow the instructions that came with the child restraint. Secure the child in the child restraint when and as the instructions say.

See the earlier part about the top strap if the child restraint has one.

1. Make the belt as long as possible by tilting the latch plate and pulling it along the belt.

2. Put the restraint on the seat.

3. Run the vehicle’s safety belt through or around the restraint. The child restraint instructions will show you how.

1-49

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

You’ll be using the lap about the top strap if the child restraint has one. Be sure to follow the instructions that came with the child restraint. Secure the child in the child restraint when and as the instructions say.

1. Because your vehicle has a right front passenger air bag, always move the seat as far back as it will go before securing a forward (See “Seats” in the Index.)

2. Put the restraint on the seat.

3. Pick up the latch plate, and run the lap and shoulder portions of the vehicle’s safety belt through or around the restraint. The child restraint instructions will show you how.

If the shoulder belt goes in front of the child’s face or neck, put it behind the child restraint.

6. T o tighten the belt, feed the lap belt back into the retractor while you push down on the child restraint. You may find it helpful to use your knee to push down on the child restraint as you tighten the belt.

7. Push and pull the child restraint in different directions to be sure it is secure.

Larger Children

Children who have outgrown child restraints should wear the vehicle’s safety belts.

If you have the choice, a child should sit next to a window so the child can wear a lap-shoulder belt and get the additional restraint a shoulder belt can provide.

Accident statistics show that children are safer if they are restrained in the rear seat. But they need to use the safety belts properly.

Children who aren’t buckled up can be thrown out in a crash.

Children who aren’t buckled up can strike other people who are.

1-54

CAUTION:

Never do this. Here two children are wearing the same belt. The

belt can’t properly spread the impact forces. In a crash, the two children can be crushed together and seriously injured. A belt must be used by only one person at a time.

Q: What if a child is wearing a lap-shoulder belt,

but the child is so small that the shoulder belt is very close to the child’s face or neck?

A: Move the child toward the center of the vehicle, but

be sure that the shoulder belt still is on the child’s shoulder, so that in a crash the child’s upper body would have the restraint that belts provide. If the child is sitting in a rear seat outside position, see “Rear Safety Belt Comfort Guides” in the Index. If the child is so small that the shoulder belt is still very close to the child’s face or neck, you might want to place the child in a seat that has a lap belt, if your vehicle has one.

1-55

CAUTION:

Never do this. Here a child is sitting in a seat that has a

lap

-shoulder belt, but the shoulder part is behind

the child. If the child wears the belt in this way, in a crash the child might slide under the belt. The belt’s force would then be applied right on the child’s abdomen. That could cause serious or fatal injuries.

Wherever the child sits, the lap portion of the belt should be worn low and snug on the hips, just touching the child’s thighs. This applies belt force to the child’s pelvic bones in a crash.

1-56

Safety Belt Extender

If the vehicle’s safety belt will fasten around you, you should use it.

But if a safety belt isn’t long enough to fasten, your dealer will order you an extender. It’s free. When you go in to order it, take the heaviest coat you will wear, so the extender will be long enough for you. The extender will be just for you, and just for the seat in your vehicle that you choose. Don’t let someone else use it, and use it only for the seat it is made to fit. T o wear it, just attach it to the regular safety belt.

Checking Your Restraint Systems

Now and then, make sure the safety belt reminder light and all your belts, buckles, latch plates, retractors and anchorages are working properly. Look for any other loose or damaged safety belt system parts. If you see anything that might keep a safety belt system from doing its job, have it repaired.

T orn or frayed safety belts may not protect you in a crash. They can rip apart under impact forces. If a belt is torn or frayed, get a new one right away.

Also look for any opened or broken air bag covers, and have them repaired or replaced. (The air bag system does not need regular maintenance.)

Replacing Restraint System Parts After a Crash

If you’ve had a crash, do you need new belts? After a very minor collision, nothing may be necessary.

But if the belts were stretched, as they would be if worn during a more severe crash, then you need new belts.

If belts are cut or damaged, replace them. Collision damage also may mean you will need to have safety belt or seat parts repaired or replaced. New parts and repairs may be necessary even if the belt wasn’t being used at the time of the collision.

If an air bag inflates, you’ll need to replace air bag system parts. See the part on the air bag system earlier in this section.

Door Locks

CAUTION:

Unlocked doors can be dangerous. Passengers -- especially children -- can easily

open the doors and fall out. When a door is locked, the inside handle won’t open it.

Outsiders can easily enter through an unlocked door when you slow down or stop your vehicle.

This may not be so obvious: You increase the chance of being thrown out of the vehicle in a crash if the doors aren’t locked. Wear safety belts properly, lock your doors, and you will be far better off whenever you drive your vehicle.

Keyless Entry System

You can lock and unlock your doors, tailgate or panel doors from about 3 feet (1 m) up to 30 feet (9 m) away using the remote keyless entry transmitter supplied with your vehicle.

Your keyless entry system operates on a radio frequency subject to Federal Communications Commission (FCC) Rules and with Industry Canada.

This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) this device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation.

This device complies with RSS Operation is subject to the following two conditions: (1) this device may not cause interference, and (2) this device must accept any interference received, including interference that may cause undesired operation of the device.

Changes or modifications to this system by other than an authorized service facility could void authorization to use this equipment.

At times you may notice a decrease in range. This is normal for any remote keyless entry system. If the transmitter does not work or if you have to stand closer to your vehicle for the transmitter to work, try this:

Check the distance. You may be too far from your vehicle. You may need to stand closer during rainy or snowy weather.

Check the location. Other vehicles or objects may be blocking the signal. T ake a few steps to the left or right, hold the transmitter higher, and try again.

Matching Transmitter(s) To Your Vehicle

Each remote keyless entry transmitter is coded to prevent another transmitter from unlocking your vehicle. If a transmitter is lost or stolen, a replacement can be purchased through your dealer. Remember to bring any remaining transmitters with you when you go to your dealer. When the dealer matches the replacement transmitter to your vehicle, any remaining transmitters must also be matched. Once your dealer has coded the new transmitter, the lost transmitter will not unlock your vehicle. Each vehicle can have only four transmitters matched to it.

Have each transmitter you intend to match ready for the next steps. T o match transmitters to your vehicle:

1. Turn the ignition to RUN, then to OFF. This will disarm the theft

2. Remove the RADIO fuse (Fuse 17). This fuse is located in the main fuse block, which is located on the left side of your main instrument panel. When the fuse block is open the radio fuse is located on the lower right hand corner of your instrument panel. See “Fuses and Circuit Breakers” in the Index.

-deterrent system.

3. Turn the ignition from OFF to RUN three times quickly (within five seconds). The vehicle will respond by locking the doors, unlocking the driver’s doors and releasing the tailgate or panel doors. Your transmitter is now ready to match the vehicle.

4. Press and hold the LOCK and UNLOCK buttons on the first transmitter for 15 seconds. The vehicle will respond as in Step 3.

5. Repeat Step 4 for the remaining transmitters.

6. When you have finished matching all of your transmitters, replace the RADIO fuse (Fuse 17).

7. Check that all transmitters work by pressing their buttons.

If the transmitters don’t work, or if you’d rather not match the transmitters yourself, see your dealer.

2-9

Battery Replacement

Under normal use, the battery in your transmitter should last about two years.

You can tell the battery is weak if the transmitter won’t work at the normal range in any location. If you have to get close to your vehicle before the transmitter works, it’s probably time to change the battery.

NOTICE:

When replacing the battery, use care not to touch any of the circuitry. Static from your body transferred to these surfaces may damage the transmitter.

Use one three volt, type CR2032, or equivalent battery.

T o replace the battery:

1. Insert a small coin, or flathead screwdriver, to separate the bottom of the transmitter from the top.

2. Remove the battery and replace it with a new one, making sure the positive (+) side of the battery is facing down.

3. Snap the top and bottom together.

4. T est the operation of the transmitter with your vehicle. If the transmitter does not work, try synchronizing the transmitter with the receiver.

2-10

Resynchronization

Resynchronization may be necessary due to the security method used by this system. The transmitter does not send the same signal twice to the receiver. The receiver will not respond to a signal it has been sent previously. This prevents anyone from recording and playing back the signal from the transmitter.

T o resynchronize your transmitter, stand close to your vehicle and simultaneously press and hold the LOCK and UNLOCK buttons on the transmitter for at least eight seconds. The door locks should cycle and the parking lamps and headlamps should flash to confirm synchronization. If this does not happen, you may need to replace the battery in your transmitter or match the transmitter to your vehicle. If the locks still do not cycle, see your dealer for service.

Rear Doors

CAUTION:

It can be dangerous to drive with the tailgate glass, tailgate or rear doors open because carbon monoxide (CO) gas can come into your vehicle. You can’t see or smell CO. It can cause unconsciousness and even death.

If you must drive with the tailgate glass, tailgate or rear doors open or if electrical wiring or other cable connections must pass through the seal between the body and the tailgate glass, tailgate or rear doors:

Make sure all other windows are shut.

Turn the fan on your heating or cooling system to its highest speed with the setting on VENT. That will force outside air into your vehicle. See “Comfort Controls” in the Index.

If you have air outlets on or under the instrument panel, open them all the way.

See “Engine Exhaust” in the Index.

2-11

Tailgate Glass and Tailgate (If Equipped)

If your vehicle has a tailgate, you must raise the rear glass before lowering the tailgate.

T o open the glass from the outside, use your key. With the key in the lock, turn the key clockwise to release the glass, then lift it up.

Theft

Vehicle theft is big business, especially in some cities. Although your vehicle has a number of theft features, we know that nothing we put on it can make it impossible to steal. However, there are ways you can help.

Key in the Ignition

If you leave your vehicle with the keys inside, it’s an easy target for joy riders or professional thieves don’t do it.

When you park your vehicle and open the driver’s door, you’ll hear a chime reminding you to remove your key from the ignition and take it with you. Always do this. Your steering wheel will be locked, and so will your ignition and transmission. Also remember to lock the doors.

Parking at Night

Park in a lighted spot, close all windows and lock your vehicle. Remember to keep your valuables out of sight. Put them in a storage area, or take them with you.

-deterrent

-- so

2-13

Parking Lots

If you park in a lot where someone will be watching your vehicle, it’s best to lock it up and take your keys. But what if you have to leave your ignition key? What if you have to leave something valuable in your vehicle?

Put your valuables in a storage area, like your glove box.

T ake the remote keyless entry system transmitter with you.

Lock all the doors except the driver’s.

Theft-Deterrent System

Your vehicle has a theft-deterrent alarm system. Once armed, the system will sound the horn and flash the parking lamps if the vehicle is tampered with.

Opening the doors may activate the alarm. See “Disarming the System” later in this section for further information on turning the system off.

Shock Sensor

A shock sensor triggers the alarm when it detects a blow to your vehicle. It is located in the center floor console. There are two levels of alarms via the shock sensor: two horn blasts and the headlamp/parking lamps flash for non

-threatening blows to the vehicle or a full

-minute alarm for harder blows to the vehicle. Its

two sensitivity can be adjusted if more or less sensitivity is desired. If sensitivity is increased too much, it may give false alarms caused by gusts of wind or other natural events that may shake the vehicle.

The adjustment for the shock sensor sensitivity can be accessed through a hole in the forward wall of the main bin of the center floor console.

2-14

Using a small flat-tipped screwdriver, turn the adjuster clockwise to increase sensitivity and turn counterclockwise to decrease sensitivity. The shock sensor is ignored by the alarm system when the ignition is on, when the tailgate or panel doors are open, when the alarm is disarmed, when customized to be ignored and for five seconds after the horn sounds an alarm or chirp. The shock sensor is ignored after triggering three full alarms until the system is rearmed.

Arming the System

The alarm system can be armed to detect break-ins by locking your vehicle using the keyless entry or by locking the doors with the power door lock switch.

Passive arming is also available if you would like the system to arm all by itself after the doors have been closed for a short time. See “Feature Customization” in the Index. When the system is armed, a red light will flash on the center floor console briefly once every two seconds. If you return to your vehicle and the red light is flashing two brief flashes every two seconds, the system is armed and the shock sensor had triggered a two minute alarm. If the red light is flashing three times every two seconds, the system is armed and there was an intrusion that sounded the alarm.

Horn chirps and parking lamp flashes can be set to your choice.

Remote Keyless Entry T ransmitter Locking

If all the doors are closed, locking the vehicle with the transmitter will immediately arm the system. The horn will chirp twice and the headlamps and parking lamps will flash, confirming that the system is armed if that mode is selected. If any door is open when the transmitter LOCK button is pressed, the system goes into an armed wait mode, waiting for the doors to close. Once they are closed, the system will arm and the headlamps and parking lamps will flash. If the tailgate or panel doors are open or ajar at the time the system is arming, the headlamps and parking lamps flash once.

Power Door Lock Switch Locking

If any door is open when the power door lock switch is pressed, the system goes into an armed wait mode, waiting for the doors to close. Once they are closed, the system will arm and the parking lamps will flash. If both of the doors are closed when the power lock switch is pressed, the system assumes you are inside the vehicle, so it will not arm. Locking the doors by using the manual door locks will not arm the system.

2-15

Passive Arming

If the LOCK button on the keyless entry transmitter or the power door lock switch is pressed, the system will arm immediately. If the ignition was just turned off and a door was opened, the system will arm six seconds after the doors, tailgate or panel doors are closed, whether or not you lock them with the manual door lock. If a door is opened without the ignition being turned on, the system will wait 30 seconds after the doors, tailgate or panel doors are closed before arming, allowing you time to get into the vehicle and put the key in the ignition. The parking lamps will flash when the system arms. Passive arming is not enabled from the factory.

Disarming the System

There are two ways to disarm the system:

1. Press the UNLOCK button on the keyless entry transmitter. If the horn chirps two or three times when you unlock the vehicle, the alarm sounded in your absence. T wo chirps means that the shock sensor was set off and three chirps means that a door, tailgate or the panel doors were opened.

2. Turn the ignition to RUN with the proper key.

For more information on customizing the features mentioned here, see “Feature Customization” in the Index.

Turning Off the Alarm

If you started the alarm by pressing the panic button on the keyless entry transmitter, you must either push that button again or turn the ignition to RUN to stop the alarm.

If the alarm is sounding due to the shock sensor or a door, tailgate or panel door opening, it can be turned off by either turning the ignition switch with a proper key inserted or by pressing any button on the keyless entry transmitter. If you use your keyless entry transmitter to silence the alarm, additional things will happen depending upon which button you press.

Pressing the UNLOCK button will turn the alarm off, unlock the driver’s door and disarm the system.

Pressing the LOCK button will turn the alarm off, keep the doors locked and keep the system armed.

Pressing the REAR 2X button will turn the alarm off and disarm the system.

Pressing the panic button will turn the alarm off, keep the doors locked and keep the system armed.

If the alarm is sounding because an incorrect ignition key was used, press any button on the keyless entry transmitter to turn the alarm off.

The alarm will stop by itself after two minutes.

Ignition Positions

You can use your key to turn your ignition switch to five different positions.

ACCESSORY (A): This position lets you use things like the radio, power windows and the windshield wipers when the engine is off. Push in the key and turn it toward you. Your steering wheel will remain locked, just as it was before you inserted the key.

LOCK (B): This position locks your ignition, steering wheel and transmission. It’s a theft You will only be able to remove your key when the ignition is turned to LOCK.

OFF (C): This position lets you turn off the engine, but still turn the steering wheel. It doesn’t lock the steering wheel like LOCK. Use OFF if you must have your vehicle in motion while the engine is off (for example, if your vehicle is being pushed).

RUN (D): This is the position for driving. START (E): This starts your engine.

-deterrent feature.

NOTICE:

If your key seems stuck in LOCK and you can’t turn it, be sure you are using the correct key; if so, is it all the way in? If it is, then turn the steering wheel left and right while you turn the key hard. But turn the key only with your hand. Using a tool to force it could break the key or the ignition switch. If none of this works, then your vehicle needs service.

2-22

Retained Accessory Power

Your vehicle is equipped with a Retained Accessory Power (RAP) feature which will allow certain features of your vehicle to continue to work up to 20 minutes after the ignition key is turned to OFF.

Your radio, power windows and console accessories will work when the ignition key is turned to RUN or ACCESSOR Y. Once the key is turned from RUN to OFF, these features will continue to work for up to 20 minutes or until a door is opened.

Starting Your Engine

Move your shift lever to PARK (P) or NEUTRAL (N). Your engine won’t start in any other position safety feature. T o restart when you’re already moving, use NEUTRAL (N) only.

-- that’s a

NOTICE:

Don’t try to shift to PARK (P) if your vehicle is moving. If you do, you could damage the transmission. Shift to PARK (P) only when your vehicle is stopped.

How to Start the Engine

1. Without pushing the accelerator pedal, turn your ignition key to STAR T. When the engine starts, let go of the key. The idle speed will go down as your engine gets warm.

NOTICE:

Holding your key in START for longer than 15 seconds at a time will cause your battery to be drained much sooner. And the excessive heat can damage your starter motor. W ait about 15 seconds between each try to help avoid draining your battery or damaging your starter.

2. If it doesn’t start right away, hold your key in STAR T. If it doesn’t start in 10 seconds, push the accelerator pedal all the way down for five more seconds, unless it starts sooner.

2-23

3. If your engine still won’t start (or starts but then stops), wait 15 seconds and start over.

When the engine starts, let go of the key and the accelerator pedal.

NOTICE:

Your engine is designed to work with the electronics in your vehicle. If you add electrical parts or accessories, you could change the way the engine operates. Before adding electrical equipment, check with your dealer. If you don’t, your engine might not perform properly.

If you ever have to have your vehicle towed, see the part of this manual that tells how to do it without damaging your vehicle. See “Towing Your Vehicle” in the Index.

Engine Coolant Heater (If Equipped)

In very cold weather, 0_F (

-18

C) or colder, the engine coolant heater can help.

You’ll get easier starting and better fuel economy during engine warm-up. Usually , the coolant heater should be plugged in a minimum of four hours prior to starting your vehicle.

2-24

To Use the Engine Coolant Heater

1. Turn off the engine.

2. Open the hood and unwrap the electrical cord. The engine coolant heater electrical cord is located

on the driver’s side of the engine compartment, near the power steering reservoir.

3. Plug it into a normal, grounded 110

-volt AC outlet.

CAUTION:

Plugging the cord into an ungrounded outlet could cause an electrical shock. Also, the wrong kind of extension cord could overheat and cause a fire. You could be seriously injured. Plug the cord into a properly grounded three 110

-volt AC outlet. If the cord won’t reach, use a

heavy

-duty three-prong extension cord rated for

at least 15 amps.

-prong

4. Before starting the engine, be sure to unplug and store the cord as it was before to keep it away from moving engine parts. If you don’t, it could be damaged.

How long should you keep the coolant heater plugged in? The answer depends on the outside temperature, the kind of oil you have, and some other things. Instead of trying to list everything here, we ask that you contact your dealer in the area where you’ll be parking your vehicle. The dealer can give you the best advice for that particular area.

2-25

Automatic Transmission Operation

There are several different positions for your shift lever. Your vehicle features an electronic shift position indicator

within the instrument cluster. This display must be powered anytime the shift lever is capable of being moved out of PARK (P). This means that if your key is in OFF, rather than LOCK, there will be a small current drain on your battery which could discharge your battery over a period of time. If you need to leave your key in the ignition in OFF for an extended period for any reason, it is recommended that you disconnect the battery cable from the battery to prevent discharging your battery.

PARK (P): This locks your rear wheels. It’s the best position to use when you start your engine because your vehicle can’t move easily.

CAUTION:

It is dangerous to get out of your vehicle if the shift lever is not fully in PARK (P) with the parking brake firmly set. Your vehicle can roll.

Don’t leave your vehicle when the engine is running unless you have to. If you have left the engine running, the vehicle can move suddenly. You or others could be injured. To be sure your vehicle won’t move, even when you’re on fairly level ground, always set your parking brake and move the shift lever to PARK (P).

See “Shifting Into PARK (P)” in the Index. If you have four roll your transfer case is in NEUTRAL. So, be sure the transfer case is in a drive gear NEUTRAL. See “Four Transfer Case)” in the Index. If you’re pulling a trailer, see “Towing a Trailer” in the Index.

REVERSE (R): Use this gear to back up.

NOTICE:

Shifting to REVERSE (R) while your vehicle is moving forward could damage your transmission. Shift to REVERSE (R) only after your vehicle is stopped.

T o rock your vehicle back and forth to get out of snow, ice or sand without damaging your transmission, see “Stuck: In Sand, Mud, Ice or Snow” in the Index.

NEUTRAL (N): In this position, your engine doesn’t connect with the wheels. T o restart when you’re already moving, use NEUTRAL (N) only. Also, use NEUTRAL (N) when your vehicle is being towed.

CAUTION:

Shifting out of PARK (P) or NEUTRAL (N) while your engine is “racing” (running at high speed) is dangerous. Unless your foot is firmly on the brake pedal, your vehicle could move very rapidly. You could lose control and hit people or objects. Don’t shift out of PARK (P) or NEUTRAL (N) while your engine is racing.

NOTICE:

Damage to your transmission caused by shifting out of PARK (P) or NEUTRAL (N) with the engine racing isn’t covered by your warranty.

2-27

AUTOMATIC OVERDRIVE (B): This position is for

normal driving. If you need more power for passing, and you’re:

Going less than about 35 mph (56 km/h), push your accelerator pedal about halfway down.

Going about 35 mph (56 km/h) or more, push the accelerator all the way down.

You’ll shift down to the next gear and have more power.

AUTOMATIC OVERDRIVE (B) can be used when towing a trailer, carrying a heavy load, driving on steep hills or for off transmission to THIRD (3) or, if necessary, a lower gear selection if the transmission shifts too often.

THIRD (3): This position is also used for normal driving, however, it offers more power and lower fuel economy than AUTOMATIC OVERDRIVE (B).

SECOND (2): This position gives you more power but lower fuel economy. You can use SECOND (2) on hills. It can help control your speed as you go down steep mountain roads, but then you would also want to use your brakes off and on.

-road driving. You may want to shift the

If you manually select SECOND (2), the transmission will drive in second gear. You may use this feature for reducing torque to the rear wheels when you are trying to start your vehicle from a stop on slippery road surfaces.

FIRST (1): This position gives you even more power (but lower fuel economy) than SECOND (2). You can use it on very steep hills, or in deep snow or mud. If the selector lever is put in FIRST (1) while the vehicle is moving forward, the transmission won’t shift into first gear until the vehicle is going slowly enough.

NOTICE:

If your rear wheels can’t rotate, don’t try to drive. This might happen if you were stuck in very deep sand or mud or were up against a solid object. You could damage your transmission.

Also, if you stop when going uphill, don’t hold your vehicle there with only the accelerator pedal. This could overheat and damage the transmission. Use your brakes or shift into PARK (P) to hold your vehicle in position on a hill.

Four-Wheel Drive

Your vehicle has four-wheel drive. You can send your engine’s driving power to all four wheels for extra traction. T o get the most satisfaction out of four-wheel drive, you must be familiar with its operation. Read the section that follows before using four should use 2HI for most normal driving conditions.
