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 all that’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 CAUTION:


These mean there is something that could hurt you or other people.


In the caution area, we tell you what the hazard is. Then we tell you what to do to help avoid or reduce the hazard. Please read these cautions. If you don’t, you or others could be hurt.


iii


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 labeis 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:


I NOTICE: I These mean there is something that could

Section 1 Seats and Restraint Systems


Here you’ll find information about the seats in your vehicle and how to use your safety belts properly. You can also learn about some things you should not do with air bags and safety belts. 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. Mar--a1 Front Seat


CAUTION:


You can lose control of the vehicle if you try to adjust a manual driver’s seat while the vehicle is 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.


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.


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 in place.


1-1


Power Driver’s Seat (Option)


Power Lumbar Control


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


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. You can use the round center knob to move the seat 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. 1-2


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.


Reclining Seatbacks Your vehicle will have one of these reclining seatback controls.


To adjust a seatback with this lever, lift the front of the lever. Release the lever to lock the seatback where you want it. Pull up on the front of the lever and the seatback will go to an upright position.


To adjust a seatback with this lever, 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.


1-3


A CAUTION:


Sitting in a reclined position when your vehicle is in motion can be dangerous. Even if you buckle up, your safety belts can’t do their job when you’re reclined like this. The shoulder belt can’t do its job because it won’t be against your body. Instead, it will be in front of you. In a crash you could go into it, receiving neck or other injuries. The lap belt can’t do its job either. In a crash the belt could go up over your abdomen. The belt forces would be there, not at your pelvic bones. This could cause serious internal injuries. For proper protection when the vehicle is in motion, have the seatback upright. Then sit well back in the seat and wear your safety belt properly.


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


1-4


traints


Head 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 in 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 all seats except the base level bench seat folds forward to let you access the rear of the cab. 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.


To fold a seatback forward on all seats except the base level bench seat, 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. 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.


Easy Entry Seat (Extended Cab Only) The driver and passenger front bucket seat and the 60/40 split bench seat of your vehicle has an easy entry feature. This makes it easy to get in and out of the rear seat. 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 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.


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


1-6


When you do, the seat bottom will release. Just pull or push the seat forward until it stops. 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.


’ A\ CAUTION:


If any easy entry seat isn’t locked, it can move. In a sudden stop or crash, the person sitting there could be injured. And, even if there is no crash or 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.


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.


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.


1-7


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. 1-8


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 (SIR), or air bag system.


de where he or she can‘t wear


Don’t let ady6h 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.


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


Why Safety Belts Work When you ride in or on anything, you go as fast as it goes.


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!


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

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

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.


e.' If my vehicle has air bags, why should I have to 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.


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.

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.


home, why should I wear safety belts?


&.’ If I’m a good driver, and I never drive far from 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 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.


1-13


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.


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.


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


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 guide. After you move the adjuster to where you want it, try to move it down without pushing in to make sure it has locked into position. Adjust the height so that the shoulder portion of the belt is centered on your shoulder. The belt should be away from your face and neck, but not falling off your shoulder.

Q: What’s wrong with this?


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


!It is


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


as much protection this way.

I A CAUTION:


You can be seriously injured i 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 i buckle your belt into the buckle nearest you.


A: The belt is buckled in the wrong place.


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.


A: The belt is over an armrest.


1-18


Q: 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.

What’s wrong with this?


A 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.


A: The belt is twisted across the body.

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


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


1-21


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.


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 an air bag. Wearing your safety belt during a crash helps reduce your chance of hitting things inside the vehicle or being ejected from it. The air bag is only a “supplemental restraint.” That is, it works with safety belts but doesn’t replace them. Air bags are designed to work only in moderate to severe crashes where the front of your vehicle hits something. They aren’t designed to inflate at all in rollover, rear, side or low-speed frontal crashes. Everyone in your vehicle, including the driver,


should wear a safety belt properly -- whether or


not there’s an air bag for that person.


1-22


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 for an air bag inflation in a crash. Always wear your safety belt, even with an air bag, and sit as far back as you can while still maintaining control of your vehicle.


’ There is an air bag


readiness light on the instrument panel, which shows AIR BAG.


AIR BAG


The system checks the air bag’s 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.


he Air Bag System Works


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


Don’t put anything on, or attach anything to, the steering wheel. Also, don’t put anything (such as pets or objects) between the driver and the steering wheel. If something is between an occupant and an air bag, it could affect the


performance of the air bag -- or worse, it could


cause injury.


When should an air bag inflate? The air bag is designed to inflate in moderate to severe frontal or near-frontal crashes. 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.


1-23


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 the vehicle’s deceleration. Vehicle damage is only one indication of this. 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 a frontal or near-frontal impact of sufficient severity, the air bag sensing system detects that the vehicle is suddenly stopping as a result of a crash. The sensing system triggers a chemical reaction of the sodium azide sealed in the inflator. The reaction produces nitrogen gas, which inflates the air bag. The inflator, air bag and related hardware are all part of the air bag module packed inside the steering wheel.


How does an air bag restrain? In moderate to severe frontal or near-frontal collisions, even belted occupants can contact the steering wheel. 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 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 the air bag. 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 the air bag inflates, it quickly deflates. This occurs so quickly that some people may not even realize the air bag inflated. Some components of the air bag module in the steering wheel hub will be hot for a short time. The part of the bag that comes into contact with you may be warm, but it will never be too hot to touch. There will be some smoke and dust coming from vents in the deflated air bag. Air bag inflation will not prevent the driver from seeing or from being able to steer the vehicle, nor will it stop people from leaving the vehicle.


1-24


1 a CAUTION:


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


inflates, then get


0 The air bag is designed to inflate only once. After it 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 the air bag module and possibly other parts. The service manual for your vehicle covers the need to replace other parts.


Your vehicle is equipped with a 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. Let only qualified technicians work on your air bag system. Improper service can mean that your air bag system won’t work properly. See your dealer for service.


NOTICE:


If you damage the cover for the driver’s air bag, it may not work properly. You may have to replace the air bag module. Do not open or break the air bag cover.


1-25

Servicing Your Air Bag-Equipped Vehicle The air bag affects 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 two minutes after the ignition key is turned off and the battery is disconnected, an air bag can still inflate during improper service. You can be injured if you are close to an air bag when it inflates. Avoid 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.


1-26


Adding Equipment to Your Air Bag-Equipped Vehicle Q: If I add a push bumper or a bicycle rack to the


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


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


attached to your vehicle so that the vehicle’s basic structure isn’t changed, it’s not likely to keep the


.I air bags from wor@ng properly in a crash.


What if I add a snow plow? Will it keep the air bag from working properly?


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.


Q=


A:


Is there anything I might add to the front of the vehicle that could keep the air bag from working properly? 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 question 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 "Customer Satisfaction Procedure" i n the Index.)


Safety 1 ___ Jse DurinP Z regnancy


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


Lap Belt If your vehicle has front and rear bench seats, someone can sit in the center positions.

Front (All)


Rear (Extended and Crew Cab)


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


Rear Seat r rssengers


It’s very important for rear seat passengers to buckle up! Accident statistics show that unbelted people in the rear seat are hurt more often in crashes than those who are wearing safety belts. Rear passengers who aren’t safety belted can be thrown out of the vehicle in a crash. And they can strike others in the vehicle who are wearing safety belts. Rear Seat Outside Passenger Positions (Extended Cab)


Front (All)


To make the belt shorter, pull its free end as shown until the belt is snug. Buckle, position and release it the same way as the lap part of a lap-shoulder belt. 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.


If you have a Crew Cab, see “Rear Seat Outside Passenger Positions (Crew Cab)” later in this section.


Lap-Shoulder Belt (Extended Cab) The positions next to the windows have lap-shoulder belts. Here’s how to wear one properly.


1. Pick up the latch plate and pull the belt across you.


Don’t let it get twisted.


2. Push the latch plate into the buckle until it clicks.


~~


If the belt stops before it reaches the buckle, tilt the latch plate and keep pulling until you can buckle it. Pull up on the latch plate to make sure it is secure. If the belt is not long enough, see “Safety Belt Extender” at the end of this section. Make sure the release button on the buckle is positioned so you would be able to unbuckle the safety belt quickly if you ever had to.

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


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.

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


A CAUTION:


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


at only 25 mph (40 k d ) , a 124b. (5.5 kg) baby will suddenly become a 2404b. (110 kg) force on your arms. The baby would be almost impossible to hold. Secure the baby in an infant restraint.

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 unless the child is an infmt and you’re the only adult in the vehicle. In that case, you might want to secure the restraint in the front seat where you can keep an eye on the baby. 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.


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. 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


Securing a Child Restraint in a Rear Outside Seat Position (Extended Cab)


If your child restraint has a top strap, it should be anchored. If you need to have an anchor installed, you can ask your GM dealer to put it in for you. If you want to install an anchor yourself, your dealer can tell you how to do it.

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


a crash.


0 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.

I A CAUTION:


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? 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.

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.


1-51


Safety Belt Extender If the vehicle‘s safety belt will hsten around you, you should use it. But ifa safety belt isn’t long enough to Faten, 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 SI ~tems 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.)


1-52


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 you ever see a label on the right front passenger’s safety belt in an Extended Cab model that says to replace the belt, be sure to do so. Then the new belt will be there to help protect you in a collision. You would see this label on the belt near the door opening. 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.

Tailgate You can open the tailgate by lifting up on its handle while pulling t.he tailgate toward you. To shut the tailgate, firmly push it away from you into the latch. When you put the tailgate back up, pull it back towara you, to be sure that it latches securely. Tailgate Removal The tailgate on your vehicle can be removed to allow for different loading situations. Although the tailgate can be removed without assistance, you may want someone to assist you with the removal to avoid possible finish damage.


Your vehicle has one double-sided key for the ignition and all door locks.


If you ever lose your keys, your dealer will be able to assist you with obtaining new ones.


NOTICE:


Your vehicle has a number of new features that can help prevent theft. But you can have a lot of . trouble getting into your vehicle if you ever lock your key inside. You may even have to damage your vehicle to get in. So be sure you have an extra key.

To remove the tailgate:


Third Door (Option)


1. Raise the tailgate


slightly and release both retaining cable clips. To release the cable clips, lift the cable so it points straight out and push the cable clips forward.


2. With the tailgate at a slight upward angle, pull back on the tailgate at the right edge and then move the tailgate to the right to release the left edge.


Reverse the above procedure to re-install. Make sure the tailgate is secure.


Your vehicle may be equipped with a third door that allows easier access to the rear area of an extended cab. To open the door, first open the passenger side front door. Then, use the handle located on the front edge of the rear door. You must close and latch the third door before you can close the front passenger door.

Door Locks


Unlocked doors can be dangerous.


Passengers -- especially children -- can easily


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.


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.


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


To unlock the door, slide the lever up.

Operation To unlock the driver’s door, press the UNLOCK button. If you press this button again within five seconds, all the doors (except the rear seat access door) will unlock. Press the LOCK button to lock all the doors (except the rear seat access door). When the UNLOCK button is pressed, the interior dome lamps are turned on for 40 seconds or until the ignition is activated. When the LOCK button is pressed, the interior lamps are turned on for a few seconds if the doors are closed. If the LOCK but.ton is pressed when a door is open, the interior lamps will stay on for a few seconds after the door is closed.


Matching Transmitter(s) To Your Vehicle Each key chain 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 the new transmitter is coded, the lost transmitter will not unlock your vehicle. Each vehicle can have only two transmitters matched to it. Battery Replacement Under normal use. the batteries in your key chain transmitter should last about two years. You can tell the batteries are 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 batteries. Use two Duraeell@ batteries type DL2014, or a similar type.

To replace the batteries:


1. Insert a dime in the side seam of the transmitter


housing, near the key ring hole.


2. Twist the dime to separate the two halves of the


transmitter housing. Separate the housing, bottom half first.


3. Remove and replace the batteries. Put the new


batteries in with the printed side down.


4. Align the housing and snap the halves together.

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 -- fast or less for the first 500 miles (804 km). Don’t drive at any one speed slow -- for the first 500 miles (804 km). Don’t make full-throttle starts. 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. 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.


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


LOCK (B): This position locks your ignition, steering wheel and transmission. It's a theft-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, if your vehicle is being pushed). RUN (D): This is the position for driving. START (E): This position starts your engine. I A CAUTION:


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.


NOTICE:


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


Key Release Button


The ignition key cannot be removed from the ignition of manual transmission vehicles unless the key release button is used.


To remove the key on manual transmission vehicles, turn the key to the OFF position, then press the button and turn the key to the LOCK position. Do not hold the button in while turning the key to OFF. Keeping your finger on the button, pull the key straight out. On automatic transmission vehicles, turn the key to LOCK and pull it straight out.

Starting Your Gasoline Engine If you have a diesel engine, see “Starting Your Diesel Engine” in the Diesel Engine Supplement. Automatic transmission Move your shift lever to PARK (P) or NEUTRAL (N). Your engine won’t start in any other position -- that’s a safety feature. To restart when you’re already moving, use NEUTRAL (N) only.


Manual transmission The gear selector should be in NEUTRAL (N). Hold the clutch pedal to the floor and start the engine. Your vehicle won’t start if the clutch pedal is not all the way down -- that’s a safety feature. 1. Without pushing the accelerator pedal, turn your


ignition key to START. When the engine starts, let go of the key. The idle speed will go down as your engine gets warm.


NOTICE:


NOTICE:


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


Holding your key in START for longer than 15 seconds at a time will cause your battery to be drained much sooner. And the excessive heat can damage your starter motor.

Engine Coolant Heater (Option) In very cold weather, 0°F (-18°C) or colder, the engine coolant heater can help.


in a minimum of four hours prior to starting


You’ll get easier starting and better fuel economy during engine warm-up. Usually, the coolant heater should be pl~~gged your vehicle. To use the coolant heater: 1. Turn off the engine. 2. Open the hood and unwrap the electrical cord. 3. Plug it into a normal, grounded 110-volt AC outlet.


3. If your engine still won’t start (or starts but then


stops), wait 15 seconds and start over. When the engine starts, let go of the key and the accelerator pedal.


I NOTICE:


Your engine is designed to work with the electronics in your vehicle. If you add electrical parts or accessories, you could change the way the engine operates. Before adding electrical equipment, check with your dealer. If you don’t, your engine might not perform properly. If you ever have to have your vehicle towed, see the part of this manual that tells how to do it without damaging your vehicle. See “Towing Your Vehicle” in the Index.

. .


Plugging the cord into an ungrounded outlet could cause an electrical shock. Also, the wrong kind of extension cord could overheat and cause a fire. You could be seriously injured. Plug the cord into a properly grounded three-prong 110-volt AC outlet. If the cord won't reach, use a heavy-duty three-prong extension cord rated for at least 15 amps.


3. After you've used the coolant heater, be sure to


store the cord a s it was before t o keep it away from moving engine parts. If you don't. it could be damaged.


How long should you keep the coolant heater plugged in'? The answer depends on the outside temperature, the kind of oil you have, and some other things. Instead of trying to list everything here, we ask that you contact your GM dealer in the area where you'll be parking your vehicle. The dea1e.r can give you the best advice for that particular area.


Automatic Transmission Operation


There are several different positions for your- shift lever. If your vehicle is equipped with an automatic transmission, it now features an electronic shift position indicator within the instrument cluster. This display must be powered anytime the shift lever is capable of being moved out of the PARK (P) position. This means that if your key is in the OFF position, rather than the LOCK position, there will be a small current drain on your battery which could discharge your battery over a period of time. If you have to leave your key in the ignition i n the OFF position for an extended period, it is recommended that you disconnect the battery cable from the battery to prevent discharging your battery.


-


will be free to roll -- even if your shift lever if’ you have four-wheel drive, your vehicle is in PARK (P) -- if your transfer case is in NEUTRAL (N). So, be sure the transfer case is in a drive gear, two-wheel high (2H) or four-wheel high (4H) or four-wheel low (4L) -- not in NEUTRAL (N). See “Shifting Into PARK (P)” in the Index. If you’re pulling a trailer, see “Towing a Trailer” in the Index.


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


It is dangerous to get out of your vehicle if the shift lever is not fully in PARK (P) with the parking brake firmly set. Your vehicle can roll. Don’t leave your vehicle when the engine is running unless you have to. If you have left the engine running, the vehicle can move suddenly. You or others could be injured. To be sure your vehicle won’t move, even when you’re on fairly level ground, always set your parking brake and move the shift lever to PARK (P).


CAUTION: (Continued)

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


NOTICE:


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

ice or sand without damaging your transmission, see “Stuck: In Sand. Mud, Ice or Snow” in the Index. NEUTRAL (N): In this position, your engine doesn’t connect with the wheels. To restart when you’re already moving, use NEUTRAL (N) only. Also, use NEUTRAL (N) when your vehicle is being towed.


I Shifting out of PARK (P) or NEUTRAL (N) while


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


I NOTICE:


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

AUTOMATIC OVERDRIVE (0): This position is for normal driving. If you need more power for passing, and you’re: 0 Going less than about 35 mph (56 km/h), push your


accelerator pedal about halfway down.


0 Going about 35 mph (56 k d h j or more, push the


accelerator all the way down.


You’ll shift down to the next gear and have more power. AUTOMATIC OVERDRIVE (GO) can be used when towing a trailer, carrying a heavy load or driving o n steep hills. You may want to shift the transmission to THIRD (3) or, if necessary, a lower gear selection if the transmission shifts too often. THIRD (3): This position is also used for normal driving, however it offers more power and lower fuel economy than AUTOMATIC OVERDRIVE (68). SECOND (2): This position gives you more power but lower fuel economy. You can use SECOND (2) on hills. It can help control your speed as you g o down steep mountain roads, but then you would also want to use your brakes off and on. If you manually select SECOND (2), the transmission will drive in second gear. You may use this feature for


2-16


reducing torque to the rear wheels when you are trying to start your vehicle from a stop on slippery road surfaces. FIRST (1): This position gives you even more power (but lower fuel economy) than SECOND (2). You can use it on very steep hills, or in deep snow or mud. If the selector lever is put in FIRST (1) while the vehicle is moving forward, the transmission won’t shift into first gear until the vehicle is going slowly enough.


NOTICE:


If your rear wheels can’t rotate, don’t try to drive. This might happen if you were stuck in very deep sand or mud or were up against a solid object. You could damage your transmission. Also, if you stop when going uphill, don’t hold your vehicle there with only the accelerator pedal. This could overheat and damage the transmission. Use your brakes or shift into PARK (P) to hold your vehicle in position on a hill.


Manual Transmission 5-Speed (with Low Gear)


Here's how to operate your transmission:


LOW (1 ) is intended only for heavy loads and is not recommended for normal driving. For normal driving conditions, start your vehicle moving in the second gear position (FIRST (2)). LOW (1): Press the clutch pedal and shift into LOW (1 ). Then, slowly let up on the clutch pedal as you press the accelerator pedal. Shift into LOW (1) only when the vehicle speed is below 5 tnph (8 kmh). If you try to shift into LOW (1) at excessive vehicle speeds, the shift lever will not move into the LOW (1) position until vehicle speed is reduced.


FIRST (2): Press the clutch pedal and shift into FIRST (2). Then. slowly let up on the clutch pedal as you press the accelerator pedal. You can shift into FIRST (2) when you're going less than 20 mph (32 k d h ) . If you've come to a complete stop and it's hard to shift into FIRST (2), put the shift lever i n NEUTRAL (N) and let up on the clutch. Press the clutch pedal back down. Then shift into FIRST ( 2 ) . If you try to shift into FIRST (2) at excessive vehicle speeds, the shift lever will not move into the FIRST (2) position until vehicle speed is reduced. SECOND (3): Press the clutch pedal a s you let up on the accelerator pedal and shift into SECOND (3). Then, slowly let up on the clutch pedal as YOLI press the accelerator pedal. THIRD (4) and FOURTH (5): Shift into the higher forward gears the same way you do for SECOND (3). Slowly let up on the clutch pedal as you press the accelerator pedal. To stop. let up on the accelerator pedal and press the brake pedal. Just before the vehicle stops, press the clutch pedal and the brake pedal, and shift to NEUTRAL (N).

NEUTRAL (N): Use this position when YOLI start or idle your engine. REVERSE (R): To back up, first press down the clutch pedal. Wait about five seconds for the internal parts to stop spinning and then shift into REVERSE (R). Let up on the clutch pedal slowly while pressing the accelerator pedal.


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


Also, use REVERSE (R), along with the parking brake, when turning off your engine and parking your vehicle.

Also, use REVERSE (R), along with the parking brake, when turning off your engine and parking your vehicle.


Shift Speeds


A CAUTION:


If you skip more than one gear when you downshift, you could lose control of your vehicle. And you could injure yourself or others. Don’t shift down more than one gear when you downshift.


NOTICE:


If you skip more than one gear when you downshift, or if you race the engine when you downshift, you can damage the engine, clutch or transmission.


2-19


If your speed drops below 20 mph (32 km/h), or if the engine is not running smoothly, you should downshift to the next lower gear. You may have to downshift two or more gears to keep the engine running smoothly or for good performance. If you have a five-speed manual transmission with low gear (RPO MW3), the following charts show when to shift to the next higher gear for best fuel economy.


Acceleration Shift Speeds VIN Code 4.3L V6 (W)


2 to 3 15 mph (24 km/h)


Cruise Shift Speeds


3 to 4 40 mph (64 km/h)


4 to 5 SO mph (80 km/h)


4.3L V6 (W)


15 rnph 45-SO mph (24 hdh) (40-64 k d h ) (72-80 km/h)


25-40 mph


Shift Light


SHIFT


If you have a manual transmission, you may have a SHIFT light. This light will show you when to shift to the next higher gear for best fuel economy.


When this light comes on, you can shift to the next higher gear if weather, road and traffic conditions let you. For the best fuel economy, accelerate slowly and shift when the light comes on. While you accelerate, it is normal for the light to go on and off if you quickly change the position of the accelerator. Ignore the SHIFT light when you downshift. If your vehicle has four-wheel drive and is equipped with a manual transmission, disregard the SHIFT light when the transfer case is in 4L.

Locking Rear Axle (Option) If you have this feature, your rear axle can give you additional traction on snow, mud, ice, sand or gravel. It works like a standard axle most of the time, but when one of the rear wheels has no traction and the other does, the locking feature will allow the wheel with traction to move the vehicle. Four- Wheel Drive If your vehicle has four-wheel drive, you can send your engine's driving power to all four wheels for extra traction. To get the most satisfaction out of four-wheel drive, you must be Familiar with its operation. Read the
