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. Index A good place to look for what you need is the Index in the back of the manual. It’s an alphabetical list of what’s in the manual, and the page number where you’ll find it.

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. A L AUTION:

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.

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.

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:

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. Manual Front Seat

A CAUTION:

If your vehicle has a manual bucket, split bench or full bench seat, you can adjust it with this lever at the front of the seat.

You can lose control of the vehicle if you try to is adjust a manual driver’s seat while the vehicle moving. The sudden movement could startle and confuse you, or make you push a pedal when you don’t want to. Adjust the driver’s seat only when the vehicle is not moving.

Slide the lever at the front of the seat toward the passenger’s side to unlock it. Using your body, slide the seat to where you want it. Then, release the lever and try to move the seat with your body in order to make sure the seat is locked into place.

1-2

Power Driver’s Seat (Option)

You can use the round center knob to move the seat to where you want it. To raise the seat, move the knob up. To lower the seat, move the knob down. To move the seat forward, move the knob toward the front of the vehicle. To move the seat rearward, move the knob toward the rear of the vehicle. You can also raise and lower the front and rear of the seat. To raise the front of the seat, move the front lever up. To lower the front of the seat, move the front lever down. To raise the rear of the seat, move the rear lever up. To lower the rear of the seat, move the rear lever down.

If your vehicle has a power seat on the driver’s side, you can adjust it with these controls at the outside edge of the seat.

1-3

Power Lumbar Control

Reclining Seatbacks

If you have power lumbar adjustment, you can increase or decrease lumbar support in an area of the lower seatback.

To 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. To 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.

To adjust the front 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.

because it

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 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.

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

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. Seatback Latches The front seatback of the base level bench seat folds forward to let you access the rear of the cab. Your seatback will move back and forth freely, unless you come to a sudden stop. Then it will lock into place. If you have a Crew Cab, your front seatback is designed not to fold forward. Access to the rear of the cab is available by using the rear doors. The front seatback of split bench seat and bucket seats fold forward to let you access the rear of the cab.

To fold a front split bench or bucket seatback forward, pull this lever forward and fold the seatback forward.

just push

To return the seatback to the upright position, the seatback rearward until it latches. After returning the seatback to its upright position, pull the seatback forward to make sure it is locked. The rear seatback of a rear bench seat without a center armrest can be folded forward to let you reach the area behind it. Your seatback will move back and forth freely, unless you come to a sudden stop. Then, it will lock into place. The Crew Cab rear seatback with a center armrest folds forward to let you access the area behind it.

To fold a seatback forward, pull this lever forward and fold the seatback forward.

To return the seatback to the upright position, just push the seatback rearward until it latches. After returning the seatback to its upright position, pull the seatback forward to make sure it is locked.

A CAUTION:

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

Easy Entry Seat (Extended Cab Only) The manual driver and passenger front bucket seat and the manual 60/40 split bench seat of your vehicle have an easy entry feature. This makes it easy to get in and out of the rear seat. On vehicles with the power driver’s seat, only the front passenger’s seat has the easy entry feature.

To operate the seat, pull forward on the top of this lever and tilt the back forward toward the front of the vehicle.

To return the seat to its regular position, return the seatback to its upright position, then push the whole seat rearward until it latches. After returning the seat to its regular position, try to move the seat with your body in order to make sure the seat is locked into place.

Rear Seat (Extended Cab) Folding the Rear Seat The extended cab may have a rear folding seat which can be folded open for more seating space. To use the seat: 1. Pull the entire seat forward until it is flat.

If any easy entry seat isn’t locked, it can move. In a sudden stop or crash, the person sitting there if there is no crash or could be injured. And, even sudden stop, a driver sitting in an unlocked easy entry seat could be startled by the sudden movement and hit the wrong control or pedal, causing an accident. After you’ve used it, be sure to push rearward on any easy entry seat to be sure it is locked.

2. Then pull forward on the

RELEASE lever under the seat cushion, on the passenger’s side of the rear seat. Push the seatback rearward until it latches.

3. After pushing the seatback upright into position, pull

the seatback forward to make sure it is locked.

1-8

The extended cab's rear seat can also be folded up to provide more cargo space. To fold the seat: 1. Pull forward on the RELEASE lever at the side of the seat cushion, behind the passenger's side front seat. Fold the seatback forward until it latches with the seat cushion.

2. Lift the entire seat and push it rearward into place.

3. Make sure the seat is secure. Rear Seat (Crew Cab) You can adjust the seat by sliding the lever at the front of the seat toward the seat support to unlock it. Then, slide the seat to where you want it. Release the lever and try to move the seat with your body in order to make sure the seat is locked into place.

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 Supplemental Inflatable Restraint system, or air bag system.

A 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.

1-9

It is extremely dangerous to ride in a cargo area, inside or outside of a vehicle. In a collision, likely to be people riding in these areas are more 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 25 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.

Put someone on it.

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

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.

@ 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 kmh). Safety belts are for everyone.

Here Are Questions Many People Ask About Safety Belts -- and the Answers @ Won’t I be trapped in the vehicle after an

accident if I’m wearing a safety belt?

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. 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 -- 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.

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.

1-15

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

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.

To 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 it, guide. After you move the adjuster to where you want try to move it down without pushing in to make sure it has locked into position.

1-16

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. &: What’s wrong with this?

’ A 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.

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

as much protection this way.

1-1 7

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.

@' What's wrong with this?

A: The belt is buckled in the wrong place.

1-18

Q: What’s wrong with this?

A: The belt is over an armrest.

A 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

@ What’s wrong with this?,

A 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.

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

be worn over the shoulder at all times.

1-20

@ What’s wrong with this?

A: The belt is twisted across the body.

You can be seriously injured by a twisted belt. In of the a crash, you wouldn’t have the full width 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.

'I 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.

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.

1-22

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

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 The right front passenger’s safety belt works the same way as the driver’s safety belt. See “Driver Position” earlier in this section. Wheri the lap belt is pulled out all the way, it will lock. (This is the child restraint locking feature working normally.) If the belt locks, let it go back all the way and start again.

Supplemental Inflatable Restraint System This part explains the Supplemental Inflatable Restraint system or air bag system.

Your vehicle may have an air bag for the driver and another air bag for the right front passenger. If it does, it will say Supplemental Inflatable Restraint on the middle part of the steering wheel.

1-23

~

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

A CAUTION: you aren’t wearing your safety belt -- even if you You can be severely injured or killed in a crash if 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 donY replace them. Air bags are to severe designed to work only in moderate crashes where the front of your vehicle hits something. They aren’t designed to inflate at all in rollover, rear, side or low-speed frontal a safety belt properly -- whether or not there’s crashes. Everyone in your vehicle should wear an air bag for that person.

A CAUTION:

Air bags inflate with great force, faster than the blink of an eye. If you’re too close to an inflating air bag, 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.

An inflating air bag can seriously injure small children. Always secure children properly in your vehicle. To read how, see the part of this manual called “Children” and the caution label on the right front passenger’s safety belt.

1-24

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

AIR BAG

How the Air Bag System Works

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.

Where are the air bags? The driver’s air bag is in the middle of the steering wheel.

A 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.

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

1-26

When should an air bag inflate? An air bag is designed to inflate in a moderate to severe frontal or near-frontal crash. The air bag will inflate 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-road usage. 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-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-frontal collisions, 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. 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 -- the steering 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.

A CAUTION:

is dust in the air. When an air bag inflates, there 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 sensors are activated and driver’s safety belt usage at deployment.

Unless you have a Crew Cab, your vehicle has a switch on the instrument panel that you can use to turn off the passenger’s air bag. But use this switch only when you want to secure a rear-facing child restraint at the right front passenger’s position. See “Securing a Child Restraint in the Right Front Seat Position” in the Index for more on this, including important safety information.

A CAUTION:

If the right front passenger’s air bag is turned off, an adult or a child who is no longer an infant sitting in the right front passenger’s position won’t have the extra protection of an air bag. In a crash, the air bag wouldn’t be able to inflate and help protect the person sitting there. Make sure the air bag is turned on unless you are using a rear-facing child restraint in the right front seat position.

,

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

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 passenger’s air bag. Do not open or break the air bag coverings.

1-30

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 GM dealer and the service manual have information about servicing your vehicle and the air bag system. To purchase a service manual, see “Service and Owner Publications’’ in the Index.

For up to 10 minutes after the ignition key is turned off and the battery is disconnected, an air bag can still inflate uring improper service. You are close to an air bag when can be injured if yo it inflates. Avoid wires wrapped with yellow tape or 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.

Adding Equipment to Your Air Bag-Equipped Vehicle &.’ 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 e.’ 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. (The phone numbers and addresses for Customer Assistance are in Step Two of the Customer Satisfaction Procedure in this manual. See “Custotner Satisfaction Procedure” in the Index.)

e.’ What if I add a snow plow? Will it keep the air A: We’ve designed our air bag systems to work properly under a wide range of conditions, including snow plowing with vehicles equipped with the optional Snow Plow Prep Package (RPO VYU). But don’t change or defeat the snow plow’s “tripping mechanism.” If you do, it can damage your snow plow and your vehicle, and it may cause an air bag inflation.

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.

Rear Safety Belt Comfort Guides for Children and Small Adults If your vehicle has a rear seat, your vehicle may have shoulder belt comfort guides. This feature 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. To 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:

To unlatch the belt, just push the button on the buckle.

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.

4. Buckle, position and release the safety belt as

described in “Rear Seat Outside Passenger Positions (Extended Cab)” or “Rear Seat Outside Passenger Positions (Crew Cab)” earlier in this section. Make sure that the shoulder belt crosses the shoulder.

To 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 or use an easy-entry seat, if your vehicle has one. Children Everyone in a vehicle needs protection! That includes infants and all children smaller than adult size. 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 /I\ 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 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 restrained in a child or infant restraint.

Never hold a baby in your arms while riding in a

vehicle. A baby doesn’t weigh much -- until a

crash. During a crash a baby will become so heavy you can’t hold it. For example, in a crash CAUTION: (Continued)

Child Restraints 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. Where to Put the Restraint (Except Extended Cab and Crew Cab) The child restraint must be secured properly in the center or right front passenger seat. If your vehicle has air bags and you want to secure a rear-facing child restraint in the right front passenger’s seat, you need to turn off the passenger’s air bag. See “Securing a Child Restraint in the Right Front Seat Position“ in the Index for more on this, including important safety information.

--

A child in a rear-facing child restraint can be seriously injured if the right front passenger’s air bag inflates. This is because the back of a rear-facing child restraint would be very close to the inflating air bag. Be sure to turn bag before using a rearfacing child restraint in the right front seat position.

Where to Put the Restraint (Extended Cab and Crew Cab) 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 the rear seat, if your vehicle has one. If you have a Crew Cab, never put a rear-facing child restraint in the right front passenger seat. Here’s why:

You may, however, secure a forward-facing child restraint in the right front seat. Before you secure a forward-facing child restraint, always move the front passenger seat as far back as it secure the child restraint in the rear seat.

If you have an Extended Cab, your vehicle has a switch on the instrument panel that you can use to turn off the passenger’s air bag. But use this switch only when you want to secure a rear-facing child restraint at the right front passenger’s position. See “Securing a Child Restraint in the Right Front Seat Position” in the Index for more on this, including important safety information.

A child in a rear-facing child restraint can be seriously injured if the right front passenger’s air bag inflates. This is because the back of a rear-facing child restraint would be very close to the inflating air bag. If you have a Crew Cab, always secure a rear-facing child restraint in the rear seat.

To turn off the right front passenger’s air bag, insert your ignition key into the switch, push in, and move the switch to AIR B A G OFF. The AIR BAG OFF light will come on to let you know that the right front passenger’s air bag is off. The right front passenger’s air bag will remain off until you turn it back on again, and the AIR B A G OFF light will stay on to remind you that the air bag is off.

A CAUTdN:

If the air bag readiness light ever comes on when you have turned off the air bag, it means that something may be wrong with the air bag system. The right front passenger’s air bag could inflate even though the switch is off. If this ever happens, don’t secure a rear-facing child restraint in your vehicle until you have your vehicle serviced.

Be sure to turn off the air bag before using a rear-facing child restraint in the right front seat position.

Larger Children

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.

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

1-62

I

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.

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 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.

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.

1-64

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.

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. 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.)

is open the doors and fall out. When a door 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.

To lock the door from the inside, slide the lever on your door down.

To unlock the door, slide the lever up.

There are several ways to lock and unlock your vehicle. From the outside, use your key or the Keyless Entry System, if your vehicle has this option.

Power Door Locks (If Equipped)

Zear Door Security Locks (Crew Cab)

Press the bottom of the power door lock switch, marked LOCK, on either front door to lock all the doors at once. Press the ribbed side of the switch to unlock all the doors at once.

With this feature, you can lock the rear doors so they can’t be opened from the inside by the passengers.

Move the lever up to engage the security feature. Move the lever down to return the door locks to normal operation. Leaving Your Vehicle If you are leaving the vehicle, take your keys, open your door and set the locks from inside. Then get out and close the door.

2-6

Keyless Entry System (If Equipped) If your vehicle has this option, you can lock and unlock your doors from about 3 feet (1 m) up to 30 feet (9 m) away using the remote keyless entry transmitter supplied with your vehicle. In addition, your interior lamps will be illuminated for a set period of time when the transmitter signal is received by the Keyless Entry System. 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-210 of Industry Canada. 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.

This system has a range of about 3 feet (1 m) up to 30 feet (9 m). 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 to determine if battery replacement or transmitter resynchronization is necessary. See the instructions that follow. Check the distance. You may be too far from your vehicle. You may need to stand closer during rainy or snowy weather.

0 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.

0 If you’re still having trouble, see your GM dealer or

a qualified technician for service.

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

Operation To unlock the driver’s door, press the UNLOCK button. If you press this button again within five seconds, all the remaining doors (except the third door) will unlock. The interior lamps will come on for 40 seconds or until the ignition is turned on. Press the LOCK button to lock all the doors (except the third door). The interior lamps will come on for two seconds as soon as all the doors are closed. 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.

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:

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.

2-8

To 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. Test the operation of the transmitter with your

vehicle. If the transmitter does not work, try synchronizing the transmitter with the receiver.

Synchronization Synchronization 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. To resynchronize your transmitter, stand close to your vehicle and simultaneously press and hold the LOCK and UNLOCK buttons on the transmitter for at least five seconds. The door locks should cycle to confirm synchronization. If the locks do not cycle, see your dealer for service. Theft Vehicle theft is big business, especially in some cities. Although your vehicle has a number of theft-deterrent 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 -- so don’t do it. When you park your vehicle and open the driver’s door, you’ll hear a tone 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. If you have an automatic transmission, taking your key out also locks your transmission. And 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. 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. Lock all the doors except the driver’s.

New Vehicle “Break-In”

NOTICE:

Your modern vehicle doesn’t need an elaborate “break-in.” But it will perform better in the long run if you follow these guidelines:

Keep your speed at 55 mph (88 km/h) or Don’t drive at any one speed -- fast or less for the first 500 miles (805 km). slow -- for the first 500 miles (805 km). Don’t make full-throttle starts.

a Avoid making hard stops for the first

200 miles (322 km) or so. During this time your new brake linings aren’t yet broken in. Hard stops with new linings can mean premature wear and earlier replacement. Follow this breaking-in guideline every time you get new brake linings.

0 Don’t tow a trailer during break-in. See

“Towing a Trailer’’ in the Index for more information.

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

ACCESSORY (A): ACCESSORY 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 towards 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-deterrent feature. 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, your vehicle is being pushed). RUN (D): This is the position for driving. START (E): This starts your engine. I- I A CAUTIO1.;

if

On manual transmission vehicles, turning the key to LOCK will lock the steering column and result in a loss of ability to steer the vehicle. This could cause a collision. If you need to turn the engine off while the vehicle is moving, turn the key only to OFF. Don’t press the key release button while the vehicle is moving.
