Front Seats

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

For information on the reclining seatbacks, see

Seatbacks on page 1-5

Your vehicle may have a memory function which allows seat settings to be saved and recalled. See

Power Lumbar

Heated Seats

You can increase or decrease lumbar support in an area of the lower seatback.

To increase support, press and hold the front of the control. To 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.

To increase support, press and hold the top of the control. To 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.

Your vehicle may have a memory function which allows seat settings to be saved and recalled. See

for more information.

Memory

The buttons used to control this feature are located on the front doors. The engine must be running for the heated seat feature to work.

To 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 heated seat off. Indicator lights will glow to designate the level of heat selected, three for high, two for medium, and one for low.

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

Page 11

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

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

Reclining 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.

{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.

Page 12

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.

The head restraints tilt forward and rearward also. To adjust the tilt for either of the front head restraints,

pull it toward you until you hear a click. There are four positions available: initial position, ﬁrst click, second click and third click. Each position will click into place. After the third position (three clicks) is reached, pulling the head restraint farther will release it back to the upright position.

Pull ﬁrmly on the top of the head restraint to position it to your liking.

The rear seat head restraints in your vehicle are adjustable. Slide an adjustable 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.

Safety Belts

Safety Belts: They Are for Everyone

This part of the manual tells you how to use safety belts properly. It also tells you some things you should not do with safety belts.

{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 on page 3-32

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

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.

They work

1-25

Page 32

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.

Take the simplest vehicle. Suppose it’s just a seat on wheels.

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

doesn’t stop.

Questions and Answers About Safety Belts

Q: Won’t I be trapped in the vehicle after an

accident if I’m wearing a safety belt?

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 safety belts – not instead of them. Every air bag 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.

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 – even one that isn’t your fault – you 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

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 or

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. To 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

Extender on page 1-47

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.

Safety Belt

1-31

Page 38

5. To 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.

1-32

Page 39

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.

1-33

Page 40

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.

1-34

Page 41

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.

1-35

Page 42

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.

1-36

Page 43

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.

1-37

Page 44

To 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.

1-38

Page 45

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.

Right Front Passenger Position

To learn how to wear the right front passenger’s safety belt properly, see

The right front passenger’s safety belt works the same way as the driver’s safety belt—except for one thing. If you ever pull the shoulder portion of the belt out all the way, you will engage the child restraint locking feature which may turn off the passenger’s frontal air bag. If this happens unintentionally, just let the belt go back all the way and start again.

Rear Seat Passengers

It is 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 are not 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 Safety Belt Comfort Guides for Children and Small Adults

Rear shoulder belt comfort guides will provide added safety belt comfort for older children who have outgrown booster seats and for small adults. When installed on a shoulder belt, the comfort guide better positions the belt away from the neck and head.

There is one guide for each passenger position in the rear seats. Here is how to install a comfort guide and use the safety belt:

Page 52

2. Place the guide over the belt and insert the two edges of the belt into the slots of the guide.

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

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. To wear it, just attach it to the regular safety belt.

Page 54

Child Restraints

Older Children

Older children who have outgrown booster seats should wear the vehicle’s safety belts.

If you have the choice, a child should sit in a seat that has a lap-shoulder belt to get the additional restraint a shoulder belt can provide.

Q: What is the proper way to wear safety belts? A: If possible, an older child should wear a

lap-shoulder belt and get the additional restraint a shoulder belt can provide. The shoulder belt should not cross the face or neck. The lap belt should ﬁt snugly below the hips, just touching the top of the thighs. It should never be worn over the abdomen, which could cause severe or even fatal internal injuries in a crash.

Accident statistics show that children are safer if they are restrained in the rear seat.

In a crash, children who are not buckled up can strike other people who are buckled up, or can be thrown out of the vehicle. Older children need to use safety belts properly.

1-48

Page 55

{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: If the child is sitting in a rear seat outside position,

move the child toward the center of the vehicle. If the child is sitting in the center position, move the child toward the safety belt buckle. In either case, 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. See

Children and Small Adults on page 1-44

Rear Safety Belt Comfort Guides for

1-49

Page 56

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.

{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.

Infants and Young Children

Everyone in a vehicle needs protection! This includes infants and all other children. 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.

1-50

Page 57

Every time infants and young children ride in vehicles, they should have the protection provided by appropriate restraints. Young children should not use the vehicle’s adult safety belts alone, unless there is no other choice. Instead, they need to use a child restraint.

{CAUTION:

People should never hold a baby in their arms while riding in a vehicle. A baby doesn’t weigh much -- until a crash. During a crash a baby will become so heavy it is not possible to hold it. For example, in a crash at only 25 mph (40 km/h), a 12-lb. (5.5 kg) baby will suddenly become a 240-lb. (110 kg) force on a person’s arms. A baby should be secured in an appropriate restraint.

1-51

Page 58

{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-shoulder belts offer outstanding protection for adults and older children, 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.

Q: What are the different types of add-on child

restraints?

A: Add-on child restraints, which are purchased by

the vehicle’s owner, are available in four basic types. Selection of a particular restraint should take into consideration not only the child’s weight, height, and age but also whether or not the restraint will be compatible with the motor vehicle in which it will be used.

1-52

Page 59

For most basic types of child restraints, there are many different models available. When purchasing a child restraint, be sure it is designed to be used in a motor vehicle. If it is, the restraint will have a label saying that it meets federal motor vehicle safety standards.

The restraint manufacturer’s instructions that come with the restraint state the weight and height limitations for a particular child restraint. In addition, there are many kinds of restraints available for children with special needs.

{CAUTION:

Newborn infants need complete support, including support for the head and neck. This is necessary because a newborn infant’s neck is weak and its head weighs so much compared with the rest of its body. In a crash, an infant in a rear-facing seat settles into the restraint, so the crash forces can be distributed across the strongest part of an infant’s body, the back and shoulders. Infants always should be secured in appropriate infant restraints.

{CAUTION:

The body structure of a young child is quite unlike that of an adult or older child, for whom the safety belts are designed. A young child’s hip bones are still so small that the vehicle’s regular safety belt may not remain low on the hip bones, as it should. Instead, it may settle up around the child’s abdomen. In a crash, the belt would apply force on a body area that’s unprotected by any bony structure. This alone could cause serious or fatal injuries. Young children always should be secured in appropriate child restraints.

1-53

Page 60

Child Restraint Systems

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

A rear-facing infant seat (B) provides restraint with the seating surface against the back of the infant. The harness system holds the infant in place and, in a crash, acts to keep the infant positioned in the restraint.

1-54

Page 61

A forward-facing child seat (C-E) provides restraint for the child’s body with the harness and also sometimes with surfaces such as T-shaped or shelf-like shields.

A booster seat (F-G) is a child restraint designed to improve the ﬁt of the vehicle’s safety belt system. Some booster seats have a shoulder belt positioner, and some high-back booster seats have a ﬁve-point harness. A booster seat can also help a child to see out the window.

1-55

Page 62

Q: How do child restraints work? A: A child restraint system is any device designed for

use in a motor vehicle to restrain, seat, or position children. A built-in child restraint system is a permanent part of the motor vehicle. An add-on child restraint system is a portable one, which is purchased by the vehicle’s owner.

For many years, add-on child restraints have used the adult belt system in the vehicle. To help reduce the chance of injury, the child also has to be secured within the restraint. The vehicle’s belt system secures the add-on child restraint in the vehicle, and the add-on child restraint’s harness system holds the child in place within the restraint.

One system, the three-point harness, has straps that come down over each of the infant’s shouldersand buckle together at the crotch. The ﬁve-point harness system has two shoulder straps, two hip strapsanda crotch strap. A shield may take the placeofhip straps. A T-shaped shield has shoulder straps that are attached to a ﬂat pad which restslowagainstthe child’s body. A shelf- or armrest-type shield has straps that are attached to a wide, shelf-likeshield that swings up or to the side.

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 or the LATCH system in your vehicle, but the child also has to be secured within the restraint to help reduce the chance of personal injury. When securing an add-on child restraint, refer to the instructions that come with the restraint which may be on the restraint itself or in a booklet, or both, and to this manual. The child restraint instructions are important, so if they are 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. General Motors recommends that child restraints be secured in a rear seat, including an infant riding in a rear-facing infant seat, a child riding in a forward-facing child seat and an older child riding in a booster seat.

Your vehicle has a rear seat that will accommodate a rear-facing child restraint. A label on your sun visor says, ″Never put a rear-facing child seat in the front.″ This is because the risk to the rear-facing child is so great, if the air bag deploys.

1-56

Page 63

{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-facing child restraint would be very close to the inﬂating air bag.

Even though the passenger sensing system is designed to turn off the passenger’s frontal air bag if the system detects a rear-facing child restraint, no system is fail-safe, and no one can guarantee that an air bag will not deploy under some unusual circumstance, even though it is turned off. General Motors recommends that rear-facing child restraints be secured in the rear seat, even if the air bag is off.

If you secure a forward-facing child restraint in the right front seat, always move the front passenger seat as far back as it will go. Itis 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 – even when no child is in it.

Top Strap

Some child restraints have a top strap, or “top tether.” It can help restrain the child restraint during a collision. For it to work, a top strap must be properly anchored to the vehicle. Some top strap-equipped child restraints are designed for use with or without the top strap being anchored. Others require the top strap always to be anchored. Be sure to read and follow the instructions for your child restraint. If yours requires that the top strap be anchored, do not use the restraint unless it is anchored properly.

1-57

Page 64

If the child restraint does not have a top strap, one can be obtained, in kit form, for many child restraints. Ask the child restraint manufacturer whether or not a kit is available.

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 the top strap to one of the following anchor points. Be sure to use an anchor point located on the same side of the vehicle as the seating position where the child restraint will be placed.

If you have an adjustable head restraint, route the top strap under it.

{CAUTION:

Each top tether bracket is designed to anchor only one child restraint. Attaching more than one child restraint to a single bracket could cause the anchor to come loose or even break during a crash. A child or others could be injured if this happens. To help prevent injury to people and damage to your vehicle, attach only one child restraint per bracket.

Once you have the top strap anchored, you will be ready to secure the child restraint itself. Tighten the top strap when and as the child restraint manufacturer’s instructions say.

Lower Anchorages and Top Tethers for Children (LATCH System)

Your vehicle has the LATCH system. You will ﬁnd anchors (A) in the center and right side passenger second row seating positions for bench seats, and the outboard passenger positions for bucket seats.

This system, designed to make installation of child restraints easier, does not use the vehicle’s safety belts. Instead, it uses vehicle anchors (A, B) and child restraint attachments to secure the restraints. Some restraints also use another vehicle anchor to secure a top tether strap (C).

1-61

Page 68

In order to use the LATCH system in your vehicle, you need a child restraint designed for that system.

To assist you in locating the lower anchors for this child restraint system, each seating position with the LATCH system has a visible metal anchorage point in the seat where the seatback meets the seat cushion.

{CAUTION:

If a LATCH-type child restraint is not attached to its anchorage points, the restraint will not be able to protect the child correctly. In a crash, the child could be seriously injured or killed. Make sure that a LATCH-type child restraint is properly installed using the anchorage points, or use the vehicle’s safety belts to secure the restraint, following the instructions that came with that restraint, and also the instructions in this manual.

1-62

Page 69

Securing a Child Restraint Designed for the LATCH System

1. Find the LATCH anchorages for the seating position you want to use, where the bottom of the seatback meets the back of the seat cushion.

2. Put the child restraint on the seat.

3. Attach and tighten the LATCH attachments on the child restraint to the LATCH anchorages in the vehicle. The child restraint instructions will show you how.

4. If the child restraint is forward-facing, attach and tighten the top tether to the top tether anchorage. The child restraint instructions will show you how. Also see

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

If a child restraint has been installed and the on indicator is lit, turn the vehicle off. Remove the child restraint from the vehicle and reinstall the child restraint.

If after reinstalling the child restraint and restarting the vehicle, the on indicator is still lit, check to make sure that the vehicle’s seatback is not pressing the child restraint into the seat cushion. If this happens, slightly recline the vehicle’s seatback and adjust the seat cushion if possible. Also make sure the child restraint is not trapped under the vehicle head restraint. If this happens, adjust the head restraint.

If the on indicator is still lit, secure the child in the child restraint in a rear seat position in the vehicle and check with your dealer.

Air Bag Systems

This part explains the frontal and side impact air bag systems.

Your vehicle has air bags – a frontal air bag for the driver and another frontal air bag for the right front passenger. Your vehicle may also have side impact air bags. Side impact air bags are available for the driver and right front passenger.

If your vehicle has a side impact air bag for the driver and/or the right front passenger, the words AIR BAG will appear on the air bag covering on the side of the seatback closest to the door.

Frontal air bags are designed to help reduce the risk of injury from the force of an inﬂating frontal air bag. But these air bags must inﬂate very quickly to do their job and comply with federal regulations.

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

{CAUTION:

You can be severely injured or killed in a crash if you are not wearing your safety belt – even if you 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 designed to work with safety belts but do not replace them.

Frontal air bags for the driver and right front passenger are designed to deploy only in moderate to severe frontal and near frontal crashes. They are not designed to inﬂate in rollover, rear or low-speed frontal crashes, or in many side crashes. And, for some unrestrained occupants, frontal air bags may provide less

CAUTION: (Continued)

1-72

Page 79

CAUTION: (Continued)

{CAUTION:

protection in frontal crashes than more forceful air bags have provided in the past.

The side impact air bags for the driver and right front passenger are designed to inﬂate only in moderate to severe crashes where something hits the side of your vehicle. They are not designed to inﬂate in frontal, in rollover or in rear crashes.

Everyone in your vehicle should wear a safety belt properly – whether or not there is an air bag for that person.

Both frontal and side impact 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 for air bag inﬂation before and during a crash. Always wear your safety belt, even with frontal air bags. The driver should sit as far back as possible while still maintaining control of the vehicle. Front occupants should not lean on or sleep against the door.

1-73

Page 80

{CAUTION:

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-shoulder belts offer 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 “Older Children” or “Infants and Young Children.”

There is an air bag readiness light on the instrument panel cluster, which shows the air bag symbol.

The system checks the air bag electrical system for malfunctions. The light tells you if there is an electrical problem. See for more information.

Air Bag Readiness Light on page 3-32

Where Are the Air Bags?

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

1-74

Page 81

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

If your vehicle has one, the driver’s side impact air bag is in the side of the driver’s seatback closest to the door.

1-75

Page 82

If your vehicle has one, the right front passenger’s side impact air bag is in the side of the passenger’s seatback closest to the door.

{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 causing severe injury or even death. 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. Don’t let seat covers block the inﬂation path of a side impact air bag.

1-76

Page 83

When Should an Air Bag Inﬂate?

Frontal Air Bags

The driver’s and right front passenger’s frontal air bags are designed to inﬂate in moderate to severe frontal or near-frontal crashes. But they are designed to inﬂate only if the impact speed is above the system’s designed “threshold level.”

In addition, your vehicle has “dual stage” frontal air bags, which adjust the amount of restraint according to crash severity. For moderate frontal impacts, these air bags inﬂate at a level less than full deployment. For more severe frontal impacts, full deployment occurs. If the front of your vehicle goes straight into a wall that doesn’t move or deform, the threshold level for the reduced deployment is about 10 to 16 mph (16 to 25 km/h), and the threshold level for a full deployment is about 20 to 25 mph (32 to 40 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 driver’s and right front passenger’s frontal air bags are not designed to inﬂate in rollovers, rear impacts, or in many side impacts because inﬂation would not help the occupant.

Seat Position Sensors

Vehicles with dual stage air bags are also equipped with special sensors which enable the sensing system to monitor the position of both the driver and passenger front seats. The seat position sensor provides information which is used to determine if the air bags should deploy at a reduced level or at full depoyment.

Side Impact Air Bags

Your vehicle may or may not have a side impact air bag. See bags are designed to inﬂate in moderate to severe side crashes. A side impact air bag will inﬂate if the crash severity is above the system’s designed “threshold level.” The threshold level can vary with speciﬁc vehicle design. Side impact air bags are not designed to inﬂate in frontal or near-frontal impacts, rollovers or rear impacts, because inﬂation would not help the occupant. A side impact air bag will only deploy on the side of the vehicle that is struck.

Air Bag Systems on page 1-72

. Side impact air

Air Bag Systems

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. For frontal air bags, inﬂation is determined by the angle of the impact and how quickly the vehicle slows down

1-77

Page 84

in frontal and near-frontal impacts. For side impact air bags, inﬂation is determined by the location and severity of the impact.

The air bag system is designed to work properly under a wide range of conditions, including off-road usage. Observe safe driving speeds, especially on rough terrain. As always, wear your safety belt. See

Operating Your All-Wheel-Drive Vehicle Off Paved Roads on page 4-16

for tips on off-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. For both frontal and side impact air bags, the sensing system triggers a release of gas from the inﬂator, which inﬂates the air bag. The inﬂator, the air bag and related hardware are all part of the air bag modules. Frontal air bag modules are located inside the steering wheel and instrument panel. For vehicles with side impact air bags, the air bag modules are located in the seatback closest to the driver’s and/or right front passenger’s door.

How Does an Air Bag Restrain?

In moderate to severe frontal or near frontal collisions, even belted occupants can contact the steering wheel or the instrument panel. In moderate to severe side collisions, even belted occupants can contact the inside of the vehicle. The air bag supplements 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 the frontal air bags would not help you in many types of collisions, including rollovers, rear impacts, and many side impacts, primarily because an occupant’s motion is not toward the air bag. Side impact air bags would not help you in many types of collisions, including frontal or near frontal collisions, rollovers, and rear 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 for the driver’s and right front passenger’s frontal air bags, and only in moderate to severe side collisions for vehicles with a driver’s and right front passenger’s side impact air bag.

1-78

Page 85

What Will You See After an Air Bag Inﬂates?

{CAUTION:

After the 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 will be hot for a short time. These components include the steering wheel hub for the driver’s frontal air bag and the instrument panel for the right front passenger’s frontal air bag. For vehicles with side impact air bags, the side of the seatback closest to the driver’s and/or right front passenger’s door will be hot. 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 the vents in the deﬂated air bags. Air bag inﬂation doesn’t prevent the driver from seeing or being able to steer the vehicle, nor does it stop people from leaving the vehicle.

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 a door. If you experience breathing problems following an air bag deployment, you should seek medical attention.

1-79

Page 86

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 an

air bag inﬂates, 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 electronic frontal

sensors which help the sensing system distinguish between a moderate and a more severe frontal impact. Your vehicle is also equipped with a crash sensing and diagnostic module, which records information about the frontal air bag system. The module records information about the readiness of the system and when the system commands air bag inﬂation. It records the status of the driver’s safety belt usage in a crash in which the air bag deploys or a crash in which the air bag nearly deploys. The module also records speed, engine rpm, brake and throttle data.

• Let only qualiﬁed technicians work on your air bag

systems. Improper service can mean that an air bag system won’t work properly. See your dealer for service.

Notice:

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

Passenger Sensing System

If your rearview mirror has one of the indicators pictured in the following illustrations, your vehicle has a passenger sensing system. The indicator will be visible when you turn your ignition key to START or RUN. The words ON and OFF or the symbol for on and off, will be visible on the rearview mirror during the system check. When the system check is complete, either the word ON or the word OFF, or the symbol for on or the symbol for off will be visible. See

Bag Status Indicator on page 3-34

mirror does not have either of the indicators pictured, then your vehicle does not have the passenger sensing system.

The passenger sensing system will turn off the right front passenger’s frontal air bag under certain conditions. The driver’s air bag and the side air bags are not part of the passenger sensing system.

The passenger sensing system works with sensors that are part of the right front passenger’s seat and safety belt. The sensors are designed to detect the presence of a properly-seated occupant and determine if the passenger’s frontal air bag should be enabled (may inﬂate) or not.

1-81

Page 88

Your vehicle has a rear seat that will accommodate a rear-facing child restraint. A label on your sun visor says, “Never put a rear-facing child seat in the front.” This is because the risk to the rear-facing child is so great, if the air bag deploys.

{CAUTION:

The passenger sensing system is designed to turn off the right front passenger’s frontal air bag if:

• the right front passenger seat is unoccupied

• the system determines that an infant is present in a

rear-facing infant seat

• the system determines that a small child is present

in a forward-facing child restraint

• the system determines that a small child is present

in a booster seat

• a right front passenger takes his/her weight off of

the seat for a period of time

• the right front passenger seat is occupied by a

smaller person, such as a child who has outgrown child restraints

• or if there is a critical problem with the air bag

system or the passenger sensing system.

1-82

Page 89

When the passenger sensing system has turned off the passenger’s frontal air bag, the off indicator will light and stay lit to remind you that the air bag is off.

If a child restraint has been installed and the on indicator is lit, turn the vehicle off. Remove the child restraint from the vehicle and reinstall the child restraint following the child restraint manufacturer’s directions and refer to

Securing a Child Restraint in the Right Front

Seat Position on page 1-68

If the on indicator is still lit, secure the child in the child restraint in a rear seat position in the vehicle and check with your dealer.

The passenger sensing system is designed to enable (may inﬂate) the right front passenger’s frontal air bag anytime the system senses that a person of adult size is sitting properly in the right front passenger’s seat. When the passenger sensing system has allowed the air bag to be enabled, the on indicator will light and stay lit to remind you that the air bag is active.

For some children who have outgrown child restraints and for very small adults, the passenger sensing system may or may not turn off the right front passenger’s frontal air bag, depending upon the person’s seating posture and body build. Everyone in your vehicle who has outgrown child restraints should wear a safety belt properly — whether or not there is an air bag for that person.

If a person of adult-size is sitting intherightfront passenger’s seat, but the offindicatorislit,itcould be because that person is not sitting properly in the seat. If this happens, turn the vehicle off and ask the person to place the seatback in the fully upright position, then sit upright in the seat, centered on the seat cushion, with the person’s legs comfortably extended. Restart the vehicle and have the person remain in this position for about two minutes. This will allow the system to detect that person and then enable the passenger’s air bag.

Servicing Your Air Bag-Equipped Vehicle

Air bags affect how your vehicle should be serviced. There air bag system parts 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. To purchase a service manual, see

Information on page 7-11

Service Publications Ordering

{CAUTION:

For up to 10 seconds 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.

Air bag systems do not need regular maintenance.

Adding Equipment to Your Air Bag-Equipped Vehicle

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

sides 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 or side 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.

Restraint System Check

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.

Torn 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

{CAUTION:

A crash can damage the restraint systems in your vehicle. A damaged restraint system may not properly protect the person using it, resulting in serious injury or even death in a crash. To help make sure your restraint systems are working properly after a crash, have them inspected and any necessary replacements made as soon as possible.

If you’ve had a crash, do you need new belts or LATCH system parts?

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 parts.

If the LATCH system was being used during a more severe crash, you may need new LATCH system parts.

If belts are cut or damaged, replace them. Collision damage also may mean you will need to have LATCH system, safety belt or seat parts repaired or replaced. New parts and repairs may be necessary even if the belt or LATCH system 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.

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. Take a few steps to the left or right, hold the transmitter higher, and try again.

• Check to determine if battery replacement is

necessary. See “Battery Replacement” under

Remote Keyless Entry System Operation on page 2-5

• If you are still having trouble, see your dealer or a

qualiﬁed technician for service.

Remote Keyless Entry System Operation

You can lock and unlock your doors from about 3 feet (1 m) up to 100 feet (30 m) away using the remote keyless entry transmitter supplied with your vehicle.

K (Unlock): Pressing this

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 a maximum of four transmitters matched to it.

Battery Replacement

Under normal use, the battery in your remote keyless entry 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:

touch any of the circuitry. Static from your body transferred to these surfaces may damage the transmitter.
