CAUTION: (Continued)


For example, in a crash at only 25 mph (40 km/h), a 12-lb. (5.5 kg) baby will suddenly become a 240-lb. (110 kg) force on a person’s arms. A baby should be secured in an appropriate restraint.


CAUTION:


People should never hold a baby in their arms while riding in a vehicle. A baby doesn’t weigh much -- until a crash. During a crash a baby will become so heavy it is not possible to hold it.


CAUTION: (Continued)

CAUTION:


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


Q: What are the different types of add-on


child restraints?


A: Add-on child restraints, which are purchased


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


For most basic types of child restraints, there are many different models available. When purchasing a child restraint, be sure it is designed to be used in a motor vehicle. If it is, the restraint will have a label saying that it meets federal motor vehicle safety standards. The restraint manufacturer’s instructions that come with the restraint state the weight and height limitations for a particular child restraint. In addition, there are many kinds of restraints available for children with special needs.


1-44


CAUTION:


CAUTION:


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


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

Restraint Systems for Children


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


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


1-46


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


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


1-47


Q: How do child restraints work? A: A child restraint system is any device designed for use in a motor vehicle to restrain, seat, or position children. A built-in child restraint system is a permanent part of the motor vehicle. An add-on child restraint system is a portable one, which is purchased by the vehicle’s owner. For many years, add-on child restraints have used the adult belt system in the vehicle. To help reduce the chance of injury, the child also has to be secured within the restraint. The vehicle’s belt system secures the add-on child restraint in the vehicle, and the add-on child restraint’s harness system holds the child in place within the restraint. One system, the three-point harness, has straps that come down over each of the infant’s shoulders and buckle together at the crotch. The five-point harness system has two shoulder straps, two hip straps and a crotch strap. A shield may take the place of hip straps.


A T-shaped shield has shoulder straps that are attached to a flat pad which rests low against the child’s body. A shelf- or armrest-type shield has straps that are attached to a wide, shelf-like shield that swings up or to the side.


When choosing a child restraint, be sure the child restraint is designed to be used in a vehicle. If it is, it will have a label saying that it meets federal motor vehicle safety standards. Then follow the instructions for the restraint. You may find these instructions on the restraint itself or in a booklet, or both. These restraints use the belt system in your vehicle, but the child also has to be secured within the restraint to help reduce the chance of personal injury. When securing an add-on child restraint, refer to the instructions that come with the restraint which may be on the restraint itself or in a booklet, or both, and to this manual. The child restraint instructions are important, so if they are not available, obtain a replacement copy from the manufacturer.

Where to Put the Restraint (Regular Cab Pickup) The child restraint must be secured properly in the right front passenger seat. If you want to secure a rear-facing child restraint in the right front passenger’s seat, turn off the passenger’s air bag. See “Air Bag Off Switch” and “Securing a Child Restraint in the Right Front Seat Position” in the Index for more on this, including important safety information.


CAUTION:


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


Keep in mind that an unsecured child restraint can move around in a collision or sudden stop and injure people in the vehicle -- even when no child is in it.


Where to Put the Restraint (Extended Cab Pickup) Accident statistics show that children are safer if they are restrained in the rear rather than the front seat. General Motors, therefore, recommends that child restraints be secured in the rear seat, including an infant riding in a rear-facing infant seat, a child riding in a forward-facing child seat and an older child riding in a booster seat. There is limited space in the rear seating area of an extended cab model. If you want to secure a child restraint in a rear seating position of an extended cab model, especially in the rear center position, be sure to study the instructions that came with your child restraint to see if there is enough room to secure your seat properly. If a forward-facing child seat must be secured in the vehicle’s right front seat, the seat should be moved back as far as possible. However, it is better to secure the restraint in a rear seat. If you want to secure a rear-facing child restraint in the right front passenger’s seat, turn off the passenger’s air bag. See “Air Bag Off Switch” and “Securing a Child Restraint in the Right Front Seat Position” in the Index for more on this, including important safety information.

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. Where to Put the Restraint (Crew Cab Pickup) Accident statistics show that children are safer if they are restrained in the rear rather than the front seat. General Motors, therefore, recommends that child restraints be secured in the rear seat, including an

infant riding in a rear-facing infant seat, a child riding in a forward-facing child seat and an older child riding in a booster seat. If a forward-facing child seat must be secured in the vehicle’s right front seat, the seat should be moved as far back as possible. However, it is better to secure the restraint in a rear seat. Never put a rear-facing child restraint in the right front passenger seat. Here’s why:


CAUTION:


A child riding in a rear-facing child restraint can be seriously injured or killed if the right front passenger’s air bag inflates. This is because the back of the rear-facing child restraint would be very close to the inflating air bag. Always secure a rear-facing child restraint in the rear seat. You may secure a forward-facing child restraint in the right front seat, but before you do, always move the front passenger seat as far back as it will go. It’s better to secure the child restraint in a rear seat.


Wherever you install it, be sure to secure the child restraint properly. Keep in mind that an unsecured child restraint can move around in a collision or sudden stop and injure people in the vehicle. Be sure to properly secure any child restraint in your vehicle -- even when no child is in it. Top Strap Some child restraints have a top strap, or “top tether.” It can help restrain the child restraint during a collision. For it to work, a top strap must be properly anchored to the vehicle. If the child restraint does not have a top strap, one can be obtained, in kit form, for many child restraints. Ask the child restraint manufacturer whether or not a kit is available.


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


1-51


Right Front Passenger Position Top Strap Anchor (All Models)


You’ll find the top strap anchor for the right front passenger seat behind the seat, near the floor.


1-52


If your vehicle is a regular cab model, there is also a top strap anchor for the right front passenger position located on the back panel of your vehicle, behind the right front passenger seat. In order to get to the anchor, you’ll have to remove the trim plug covering it. Once you have the top strap anchored, you’ll be ready to secure the child restraint itself. Tighten the top strap when and as the child restraint manufacturer’s instructions say.


Rear Seat Top Strap Anchors (Extended Cab Models)


If your vehicle is an extended cab model, you’ll find the top strap anchors for the rear seating positions near the top of the seatback. In addition to the top strap anchors, each seating position has a fabric loop at the top of the seatback that you’ll use to route a top strap through.


When using a child restraint with a top strap in either rear outboard position, raise the head restraint and route the top strap through the fabric loop on the seatback. Then, attach the top strap to the anchor point at the center rear seating position.


1-53


Rear Seat Top Strap Anchors (Crew Cab Models)


When using a child restraint with a top strap in the center rear position, route the top strap through the fabric loop on the seatback. Then, raise the head restraint and attach the top strap to the anchor point located at the closest outboard position. Once you have the top strap anchored, you’ll be ready to secure the child restraint itself. Tighten the top strap when and as the child restraint manufacturer’s instructions say.


1-54


If you vehicle is a crew cab model, you’ll find top strap anchors for the rear seating positions located on the back panel of your vehicle, behind the rear seat. In order to get to the brackets, you’ll have to remove the trim plugs covering them.


There are also anchorage points at the rear base of the front passenger’s seat. Anchor the top strap to one of these anchor points. Be sure to use an anchor point located on the same side of the vehicle as the seating position where the child restraint will be placed. Raise the head restraint and route the top strap under it. Once you have the top strap anchored, you’ll be ready to secure the child restraint itself. Tighten the top strap when and as the child restraint manufacturer’s instructions say.


Lower Anchorages and Top Tethers for Children (LATCH System) Your vehicle may have the LATCH system. If it does, you’ll find anchors in the rear of the seat cushion. For front passenger seat positions, there is an anchor behind and to the bottom of the seat to secure the top strap. For rear center seat positions, there is an anchor near the driver’s side rear seat head restraint.


1-55


In order to use the system, you need either a forward-facing child restraint that has attaching points (A) at its base and a top tether anchor (B), or a rear-facing child restraint that has attaching points (A), as shown here.


CAUTION:


If a LATCH-type child restraint isn’t attached to its anchorage points, the restraint won’t be able to protect a child sitting there. In a crash, the child could be seriously injured or killed. Make sure that a LATCH-type child restraint is properly installed using the anchorage points, or use the vehicle’s safety belts to secure the restraint. See “Securing a Child Restraint in the Center Rear Seat Position (Extended Cab) and (Crew Cab)” or “Securing a Child Restraint in the Right Front Seat Position” in the Index for information on how to secure a child restraint in your vehicle using the vehicle’s safety belts.


With this system, use the LATCH system instead of the vehicle’s safety belts to secure a child restraint.


1-56


Securing a Child Restraint Designed for the LATCH System D Find the anchors for the seating position you want to use, where the bottom of the seatback meets the back of the seat cushion.


D Put the child restraint on the seat. D Attach the anchor points on the child restraint to


the anchors in the vehicle. The child restraint instructions will show you how.


D Attach the top strap to the top strap anchor.


See “Top Strap” in the Index. Tighten the top strap according to the child restraint instructions.


D Push and pull the child restraint in different


directions to be sure it is secure.


To remove the child restraint, simply unhook the top strap from the top tether anchor and then disconnect the anchor points.


Securing a Child Restraint in a Rear Outside Seat Position (Extended Cab and Crew Cab) There is limited space in the rear seating area of an extended cab model. If you want to secure a child restraint in a rear outside seating position, be sure to study the instructions that came with your child restraint to see if there is enough room to secure your seat properly.


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


1-57


1. Put the restraint on the seat. 2. Pick up the latch plate, and run the lap and shoulder


portions of the vehicle’s safety belt through or around the restraint. The child restraint instructions will show you how. If the shoulder belt goes in front of the child’s face or neck, put it behind the child restraint.


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


1-58


4. Pull the rest of the shoulder belt all the way out of


the retractor to set the lock.


Securing a Child Restraint in the Center Front Seat Position


Don’t use child restraints in this position. The restraints won’t work properly.


1-59


5. To tighten the belt, feed the shoulder belt back into the


retractor while you push down on the child restraint. If you’re using a forward-facing child restraint, you may find it helpful to use your knee to push down on the child restraint as you tighten the belt.


6. Push and pull the child restraint in different


directions to be sure it is secure.


To remove the child restraint, just unbuckle the vehicle’s safety belt and let it go back all the way. The safety belt will move freely again and be ready to work for an adult or larger child passenger.


Securing a Child Restraint in the Center Rear Seat Position (Extended Cab and Crew Cab)


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


If you have an extended cab or a crew cab pickup, you can secure a child restraint in the center rear seat position. There is limited space in the rear seating area of an extended cab model. If you want to secure a child restraint in a rear seating position of an extended cab model, especially in the rear center position, be sure to study the instructions that came with your child restraint to see if there is enough room to secure your seat properly.

1. Make the belt as long as possible by tilting the latch


plate and pulling it along the belt.


2. Put the restraint on the seat.


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


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


5. To tighten the belt, pull its free end while you


push down on the child restraint. If you’re using a forward-facing child restraint, you may find it helpful to use your knee to push down on the child restraint as you tighten the belt.


6. Push and pull the child restraint in different


directions to be sure it is secure.


To remove the child restraint, just unbuckle the vehicle’s safety belt. It will be ready to work for an adult or larger child passenger.

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


1-62


CAUTION:


A child in a rear-facing child restraint can be seriously injured or killed if the right front passenger’s air bag inflates. This is because the back of the rear-facing child restraint would be very close to the inflating air bag. Be sure to turn off the air bag before using a rear-facing child restraint in the right front seat position. If a forward-facing child restraint is suitable for your child, always move the passenger seat as far back as it will go.


CAUTION:


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.


CAUTION: (Continued)


CAUTION: (Continued)


If this ever happens, don’t let anyone whom the national government has identified as a member of a passenger air bag risk group sit in the right front passenger’s position (for example, don’t secure a rear-facing child restraint in your vehicle) until you have your vehicle serviced. See “Air Bag Off Switch” in the Index.


Crew Cab Models: Your vehicle has a right front passenger air bag. Never put a rear-facing child restraint in this seat. Here’s why:


CAUTION:


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


Although a rear seat is a safer place, you can secure a forward-facing child restraint in the right front seat.


Regular Cab and Extended Cab Models: Your vehicle has a right front passenger air bag. There’s a switch on the instrument panel that you can use to turn off the right front passenger’s air bag when you want to secure a rear-facing child restraint at the right front passenger’s position.

7. Push and pull the child restraint in different


directions to be sure it is secure.


1-66


Older Children


Older children who have outgrown booster seats should wear the vehicle’s safety belts. If you have the choice, a child should sit next to a window so the child can wear a lap-shoulder belt and get the additional restraint a shoulder belt can provide.


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


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


Accident statistics show that children are safer if they are restrained in the rear seat. In a crash, children who are not buckled up can strike other people who are buckled up, or can be thrown out of the vehicle. Older children need to use safety belts properly.


1-67


CAUTION:


Never do this. Here two children are wearing the same belt. The belt can’t properly spread the impact forces. In a crash, the two children can be crushed together and seriously injured. A belt must be used by only one person at a time.


Q: What if a child is wearing a lap-shoulder belt, but the child is so small that the shoulder belt is very close to the child’s face or neck?


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


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


1-68


CAUTION:


Never do this. Here a child is sitting in a seat that has a lap-shoulder belt, but the shoulder part is behind the child. If the child wears the belt in this way, in a crash the child might slide under the belt. The belt’s force would then be applied right on the child’s abdomen. That could cause serious or fatal injuries.


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


1-69


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.)

Windows


CAUTION:


Leaving children in a vehicle with the windows closed is dangerous. A child can be overcome by the extreme heat and can suffer permanent injuries or even death from heat stroke. Never leave a child alone in a vehicle, especially with the windows closed in warm or hot weather.


2-2


Manual Windows Turn the hand crank on each door to raise or lower manual windows.


Power Windows (If Equipped)


If your vehicle is equipped with power windows, the controls are located on each of the side doors in the front and rear.


The express down mode can be canceled at any time by pressing the opposite side of the switch. To open the window partway, lightly tap the switch until the window is at the desired position.


The driver’s door has a switch for the passenger window as well. Your power windows will work when the ignition has been turned to ACCESSORY or RUN or when Retained Accessory Power (RAP) is present. See “Retained Accessory Power” in the Index. Press the rear of the switch with the power window symbol on it to lower or raise the window. The driver’s window also has an express down feature that allows the window to be lowered without holding the switch. Press and hold the rear of the window switch for one second to activate the express down mode.


If you have power windows on a Crew Cab, the driver’s door power window switch has a lockout feature. This feature prevents the rear windows from operating except from the driver’s position when the driver’s door button labeled WINDOW LOCK is engaged. When the button is not engaged, the rear power windows will operate.

Swing-Out Windows (Extended Cab)


To open a rear swing-out window, flip the latch open and swing the glass out.


Sliding Rear Window (If Equipped) To open the sliding rear window, unlock the latch lever by pushing the lever toward the passenger’s side of the vehicle. Release the lever from the latch plate and slide the window toward the passenger’s side of the vehicle. To close the window, slide the window toward the driver’s side of the vehicle. The latch lever will automatically snap on to the latch plate. Try to open the window without releasing the latch lever to be sure the window is in the locked position.


The latch will catch when the window is fully open and it will also hold it in the open position.

easily open the doors and fall out of a moving vehicle. When a door is locked, the handle won’t open it. You increase the chance of being thrown out of the vehicle in a crash if the doors aren’t locked. So, wear safety belts properly and lock the doors whenever you drive.


D Young children who get into unlocked


vehicles may be unable to get out. A child can be overcome by extreme heat and can suffer permanent injuries or even death from heat stroke. Always lock your vehicle whenever you leave it.


D Outsiders can easily enter through an


unlocked door when you slow down or stop your vehicle. Locking your doors can help prevent this from happening.


Your vehicle may also have a key that locks and unlocks only the center floor console (if equipped).


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


2-6


There are several ways to lock and unlock your vehicle. You can use the keyless entry system (if equipped). You can also use your key.

Power Door Locks (If Equipped)


If your vehicle has this power door lock switch, press the raised side of the switch, marked “L” on either front door to lock all the doors at once.


Press the recessed side of the switch marked “U” to unlock all the doors at once.


2-7


If your vehicle has this power door lock switch, press the bottom of the switch on either front door to lock all the doors at once.


Press the top of the switch to unlock all the doors at once. The power door locks will operate at any time without the ignition being on. The power door locks will also automatically lock when the vehicle reaches 15 mph (24 km/h). To unlock the doors, refer to the instructions listed previously. The automatic locking feature can be disabled, if you prefer. See “Programmable Automatic Door Locks” in the following text. Operating the power locks may interact with the theft-deterrent system (if equipped). See “Content Theft-Deterrent” in the Index.


2-8


Programmable Automatic Door Locks Your vehicle is equipped with an auto lock/unlock feature which enables you to program your power door locks. Your vehicle left the factory programmed to have the automatic lock feature lock all the doors when the vehicle speed is greater than 15 mph (24 km/h) for two seconds, and then unlock all the doors once the key is removed from the ignition. The following instructions detail how to program your door locks. To enter the program mode you need to do the following: 1. Beginning with the ignition in OFF, pull back on the


turn signal/multifunction lever all the way toward you and hold it while you perform the next step.


2. Turn your key to ON and OFF twice. Then, with the


key in OFF, release the turn signal/multifunction lever. Once you do this, you will hear the lock switch lock and unlock.


3. You are now ready to program the automatic door


locks. Select one of the following four programming options and follow the instructions. You will have ten seconds to begin programming. If you exceed the ten second limit, the locks will automatically lock and unlock to indicate you have left the program mode.


If this occurs, repeat the procedure beginning with Step 1. You can exit the program mode any time by turning the ignition to ON (the locks will automatically lock and unlock to indicate you are leaving the program mode). If the lock/unlock switches are not pressed while in the programming mode, the auto lock/unlock setting will not be modified.


The following is a list of the available programming options: D All doors lock/Only the driver’s door unlocks:


Press the lock side of the power lock switch on the door panel once and then the unlock side once. This option is unavailable on most vehicles not equipped with keyless entry.


D All doors lock/All doors unlock: Press the lock side of the power lock switch on the door panel once, and then the unlock side twice (this is the factory setting). D All doors lock/None of the doors unlock: Press the lock side of the power lock switch on the door panel once, and then the unlock side three times.


D No doors lock/None of the doors unlock: Press the lock side of the power lock switch on the door panel twice. This turns off the automatic lock feature.


For more information, see your dealer.


Lockout Prevention To protect you from locking your key in the vehicle, this feature stops the power door locks from locking when the key is in the ignition and a door is open. If the power lock switch is pressed when a door is open and the key is in the ignition, all of the doors will lock and then the driver’s door will unlock. Child Security Locks (Crew Cabs) (If Equipped)


With this feature, you can lock the rear side doors so that they cannot be opened from the inside by passengers. This feature is located on the inside of the rear doors.


Move the button forward to engage the security feature. Move the button rearward to return the door locks to normal operation.


2-9


Keyless Entry System (If Equipped) If your vehicle has this feature, you can lock and unlock your doors from about 3 feet (1 m) up to 100 feet (30 m) away using the remote keyless entry transmitter supplied with your vehicle. 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. Changes or modifications to this system by other than an authorized service facility could void authorization to use this equipment.


At times you may notice a decrease in range. This is normal for any remote system. If the transmitter does not work or if you have to stand closer to your vehicle for the transmitter to work, try this: D Check the distance. You may be too far from your vehicle. You may need to stand closer during rainy or snowy weather.


D 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.


D Check to determine if battery replacement or


resynchronization is necessary. See the instructions that follow.


D If you’re still having trouble, see your dealer or a


qualified technician for service.


Operation UNLOCK: Pressing this button once will unlock the driver’s door. The parking lamps will flash and the interior lights will come on. Pressing UNLOCK again within three seconds will cause the remaining doors to unlock. The parking lamps will flash and the interior lights will come on.


2-10


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.


LOCK: Pressing this button once will lock all of the doors. Press LOCK again within three seconds and the horn will chirp. Operating the keyless entry transmitter may interact with the theft-deterrent system. See “Content-Theft Deterrent” in the Index.


Remote Panic Alarm When the button with the horn symbol on the keyless entry transmitter is pressed, the horn will sound and the headlamps and taillamps will flash for up to 30 seconds. This can be turned off by pressing the horn button again, waiting for 30 seconds, or starting the vehicle. 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.


2-11


To replace the battery in the keyless entry transmitter, do the following:


Resynchronization Resynchronization may be necessary due to the security method used by this system. The transmitter does not send the same signal twice to the receiver. The receiver will not respond to a signal that 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 press and hold the LOCK and UNLOCK buttons on the transmitter at the same time for seven seconds. The door locks should cycle to confirm synchronization. If the locks do not cycle, see your dealer for service.


1. Insert a dime in the slot between the covers of the


transmitter housing near the key ring hole. Remove the bottom by twisting the dime.


2. Remove and replace the battery with a three-volt


CR2032 or equivalent battery, positive (+) side up.


3. Align the covers and snap them together. 4. Resynchronize the transmitter. 5. Check the operation of the transmitter.


2-12


Rear Doors Your vehicle may be equipped with a rear access door(s) that allows easier access to the rear area of the extended cab.


To open a rear access door from the outside, first open the front door. Then, use the handle located on the front edge of the rear access door to open it.


You must fully close a rear access door before you can close the front door.


To open a rear access door from the inside, the front door must be opened first. Then, use the handle located on the inside of the rear access door to open it.


If your vehicle is a Crew Cab, you can open your doors from the inside or outside. Your vehicle may also have a feature which prevents children from opening rear doors. See “Child Security Locks” in the Index for more information.


2-13


Tailgate You can open the tailgate by lifting up on its handle while pulling the tailgate toward you. To shut the tailgate, firmly push it upward until it latches. After you put the tailgate back up, pull it back towards you to be sure 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 damage to the vehicle.


To remove the tailgate, do the following:


1. Raise the tailgate


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


2-14


Reverse the above procedure to reinstall. Make sure the tailgate is secure.


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 chime reminding you to remove your key from the ignition and take it with you. Always do this. If you have a manual transmission, your steering wheel will be locked, and so will your ignition. If you have an automatic transmission, your ignition and transmission will be locked. Also remember to lock the doors. If the key is in the ignition, with any door open, and you try to lock your doors with the power door locks, the driver’s door will not stay locked. This will help to keep you from locking your keys in the vehicle.


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 Even if you park in a lot where someone will be watching your vehicle, it’s still 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? D Put your valuables in a storage area, like your


glove box.


D Valuables can be locked in the center floor console. D If your vehicle has a remote keyless entry system,


take the transmitter with you.


D Lock all the doors except the driver’s.


2-15


Content Theft-Deterrent (If Equipped) Your vehicle may be equipped with a Content Theft-Deterrent alarm system.


With this system, the SECURITY message will flash as you open the door (if your ignition is off).


This message reminds you to activate the theft-deterrent system. Here’s how to do it: 1. Open the door. 2. Lock the door with the power door lock switch or the


remote keyless entry transmitter. The SECURITY message should come on and stay on. If using the remote keyless entry transmitter, the door does not need to be open.


3. Close all doors. The SECURITY message should go off after approximately 15 seconds. The alarm is not armed until the SECURITY message goes off.


2-16


If a door is opened without the key or the remote keyless entry transmitter, the alarm will go off. Your vehicle’s headlamps will flash and the horn will sound for about two minutes, then will turn off to save the battery power. Remember, the theft-deterrent system won’t activate if you lock the doors with a key or use the manual door lock. It activates only if you use a power door lock switch with the door open, or with the remote keyless entry transmitter. You should also remember that you can start your vehicle with the correct ignition key if the alarm has been set off. Here’s how to avoid setting off the alarm by accident: D If you don’t want to activate the theft-deterrent


system, the vehicle should be locked with the door key after the doors are closed.


D Always unlock a door with a key, or use the remote keyless entry transmitter. Unlocking a door any other way will set off the alarm if the system has been armed.


If you set off the alarm by accident, unlock any door with the key. You can also turn off the alarm by pressing UNLOCK on the remote keyless entry transmitter or by placing the key in the ignition and turning it to START.


Testing the Alarm The alarm can be tested by following these steps: 1. From inside the vehicle, lower the driver’s window


and open the driver’s door.


2. Activate the system by locking the doors with the power door lock switch while the door is open, or with the remote keyless entry transmitter.


3. Get out of the vehicle, close the door and wait for the


SECURITY message to go out.


4. Then reach in through the window, unlock the door


with the manual door lock and open the door. This should set off the alarm.


If the alarm does not sound when it should but the vehicle’s headlamps flash, check to see if the horn works. The horn fuse may be blown. To replace the fuse, see “Fuses and Circuit Breakers” in the Index. If the alarm does not sound or the vehicle’s headlamps do not flash, the vehicle should be serviced by an authorized service center.


PasslockR Your vehicle is equipped with the Passlock theft-deterrent system. Passlock is a passive theft-deterrent system. Passlock enables fuel if the ignition lock cylinder is turned with a valid key. If a correct key is not used or the ignition lock cylinder is tampered with, fuel is disabled. If the engine stalls and the SECURITY message flashes, wait until the light stops flashing before trying to restart the engine. Remember to release the key from START as soon as the engine starts. If the engine is running and the SECURITY message comes on, you will be able to restart the engine if you turn the engine off. However, your Passlock system is not working properly and must be serviced by your dealer. Your vehicle is not protected by Passlock at this time. You may also want to check the fuse (see “Fuses and Circuit Breakers” in the Index). See your dealer for service. In an emergency, call the GM Roadside Assistance Center. See “Roadside Assistance” in the Index.


2-17


New Vehicle “Break-In”


NOTICE:


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


Your vehicle doesn’t need an elaborate “break-in.” But it will perform better in the long run if you follow these guidelines: D Keep your speed at 55 mph (88 km/h) or


less for the first 500 miles (805 km).


D Don’t drive at any one speed -- fast or slow -- for the first 500 miles (805 km). Don’t make full-throttle starts.


D 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.


D Don’t tow a trailer during break-in.


See “Towing a Trailer” in the Index for more information.


2-18


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 toward you.


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


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 you are using the correct key; if so, is it all the way in? 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.


OFF (C): This position lets you turn off the engine. 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.


2-19


Key Release Button (Manual Transmission)


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 OFF, then press the button and turn the key to LOCK. Do not hold the button in while turning the key to OFF. Pull the key straight out. Retained Accessory Power (RAP) (If Equipped) Your vehicle may be equipped with a Retained Accessory Power (RAP) feature which will allow certain features on your vehicle to continue to work up to 20 minutes after the ignition key is turned to OFF.


2-20


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


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.


Manual Transmission The gear selector should be in NEUTRAL and the parking brake engaged. 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.


Starting Your V8 Engine 1. With your foot off the accelerator pedal, turn the


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:


2.


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. Wait about 15 seconds between each try to help avoid draining your battery or damaging your starter.


2. If it doesn’t start within 10 seconds, push the


accelerator pedal all the way to the floor, while you hold the ignition key in START. When the engine starts, let go of the key and let up on the accelerator pedal. Wait about 15 seconds between each try.


When starting your engine in very cold weather (below 0_F or -18_C), do this: 1. With your foot off the accelerator pedal, turn the


ignition key to START and hold it there. When the engine starts, let go of the key. Use the accelerator pedal to maintain engine speed, if you have to, until your engine has run for a while. If your engine still won’t start (or starts but then stops), it could be flooded with too much gasoline. Try pushing your accelerator pedal all the way to the floor and holding it there as you hold the key in START for about three seconds. When the engine starts, let go of the key and accelerator. If the vehicle starts briefly but then stops again, do the same thing, but this time keep the pedal down for five or six seconds. This clears the extra gasoline from the engine.


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.


2-21


Starting Your V6 Engine 1. With your foot off 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.


3. If your engine still won’t start (or starts but then stops), wait 15 seconds and start over. When the engine starts, let go of the key and the accelerator pedal.


NOTICE:


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


NOTICE:


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


2. If it doesn’t start within 10 seconds, hold your key in START for not more than 10 seconds. Then, push the accelerator pedal all the way down for five more seconds, unless it starts sooner.


2-22


Engine Coolant Heater (If Equipped)


In very cold weather, 0_F (-18_C) or colder, the engine coolant heater can help. You’ll get easier starting and better fuel economy during engine warm-up. Usually, the coolant heater should be plugged in a minimum of four hours prior to starting your vehicle.


To Use the Engine Coolant Heater 1. Turn off the engine. 2. Open the hood and unwrap the electrical cord.


The cord is located on the driver’s side of the engine compartment, near the power steering fluid reservoir.


3. Plug it into a normal, grounded 110-volt AC outlet.


CAUTION:


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


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


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


2-23


Automatic Transmission Operation


If your vehicle is equipped with an automatic transmission, it features an electronic shift position indicator within the instrument panel cluster. This display must be powered anytime the shift lever is capable of being moved out of PARK (P). This means that if your key is in OFF, rather than LOCK, there will be a small current drain on your battery which could discharge your battery over a period of time. If you have to leave your key in the ignition in OFF for an extended period, it is recommended that you remove the IGN 0 fuse from the instrument panel fuse block. See “Fuses and Circuit Breakers” in the Index. There are several different positions for your shift lever.


2-24


PARK (P): This position locks your rear wheels. It’s the best position to use when you start your engine because your vehicle can’t move easily. If your vehicle is equipped with the AllisonR Transmission, use park for stationary operation of the Power Takeoff (PTO) (if equipped).


CAUTION:


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


CAUTION: (Continued)


CAUTION: (Continued)


If you have four-wheel drive, your vehicle will be free to roll -- even if your shift lever is in PARK (P) -- if your transfer case is in NEUTRAL. 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. See “Shifting Into PARK (P)” in the Index. If you’re pulling a trailer, see “Towing a Trailer” in the Index.


REVERSE (R): Use this gear to back up. If your vehicle is equipped with the Allison Transmission, the “R” may blink on the PRNDL if the shift inhibitor is active.


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. If your vehicle is equipped with the Allison Transmission, do not idle in REVERSE (R) for more than five minutes. Extended idling in REVERSE (R) may cause transmission overheating and damage. Always select PARK (P) whenever idle time exceeds five minutes.


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


2-25


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.


CAUTION:


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


NOTICE:


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


DRIVE (D): This position is for normal driving. If you need more power for passing, and you’re: D Going less than about 35 mph (55 km/h), push your


accelerator pedal about halfway down.


D Going about 35 mph (55 km/h) or more, push the


accelerator all the way down.


You’ll shift down to the next gear and have more power. DRIVE (D) can be used when towing a trailer, carrying a heavy load, driving on steep hills or for off-road driving. You may want to shift the transmission to THIRD (3) or, if necessary, a lower gear selection if the transmission shifts too often.


NOTICE:


If your vehicle is equipped with the Allison Transmission, do not idle in DRIVE (D) for more than five minutes. Extended idling in DRIVE (D) may cause transmission overheating and damage. Always select PARK (P) if idle time is longer than five minutes.


2-26


If your vehicle is equipped with the Allison Transmission, it will initially attain first range when DRIVE (D) is selected. As vehicle speed increases, the transmission will upshift automatically through each available range up to FIFTH (5). As the vehicle slows, the transmission will downshift automatically. THIRD (3): This position is also used for normal driving, however it offers more power and lower fuel economy than DRIVE (D). SECOND (2): This position gives you more power but lower fuel economy. You can use SECOND (2) on hills. It can help control your speed as you go down steep mountain roads, but then you would also want to use your brakes off and on. If you manually select SECOND (2) in a light duty automatic transmission, the transmission will drive in second gear. You may use this feature for reducing the speed of 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.


On cold days, approximately 32_F (0_C) or colder, your transmission is designed to shift differently until the engine reaches normal operating temperature. This is intended to improve heater performance.


2-27


Tow/Haul Mode Selector Switch (Automatic Transmission)


Manual Transmission Operation 5-Speed (VORTEC 6000 V8 Engine)


Here’s how to operate your transmission.


Your vehicle is equipped with a tow/haul mode. The selector switch is located on the end of the column shift lever. You can use this feature to assist when towing or hauling a heavy load. See “Tow/Haul Mode” in the Index for more information.


FIRST (1) is intended only for heavy loads or trailer towing and is not recommended for normal driving. During the first 500 miles (805 km) of vehicle use, start your vehicle moving in FIRST (1). This allows clutch components to break-in properly.

SECOND (2): Press the clutch pedal and shift into SECOND (2). Then, slowly let up on the clutch pedal as you press the accelerator pedal. You can shift into SECOND (2) when you’re going less than 20 mph (32 km/h). If you’ve come to a complete stop and it’s hard to shift into SECOND (2), put the shift lever into NEUTRAL and let up on the clutch. Press the clutch pedal back down. Then shift into SECOND (2). If you try to downshift into SECOND (2) at excessive vehicle speeds, the shift lever will not move into the SECOND (2) position until the vehicle speed is reduced. THIRD (3): Press the clutch pedal and shift into THIRD (3). Then, slowly let up on the clutch pedal as you press the accelerator pedal.


FOURTH (4) and FIFTH (5): Shift into the higher forward gears the same way you do for THIRD (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. NEUTRAL: Use this position when you start or idle your engine. REVERSE (R): To back up, first press down the clutch pedal. Wait for the vehicle to stop moving 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.


2-29


NEUTRAL: Use this position when you start or idle your engine. REVERSE (R): To back up, first press down the clutch pedal. Wait for the vehicle to stop moving 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.


5-Speed (VORTEC 4300 V6 and 4800 V8 Engines) Here’s how to operate your transmission: FIRST (1): Press the clutch pedal and shift into FIRST (1). Then, slowly let up on the clutch pedal as you press the accelerator pedal. You can shift into FIRST (1) when you’re going less than 20 mph (32 km/h). If you’ve come to a complete stop and it’s hard to shift into FIRST (1), put the shift lever into NEUTRAL and let up on the clutch. Press the clutch pedal back down. Then shift into FIRST (1). SECOND (2): Press the clutch pedal as you let up on the accelerator pedal and shift into SECOND (2). Then, slowly let up on the clutch pedal as you press the accelerator pedal. THIRD (3), FOURTH (4) and FIFTH (5): Shift into THIRD (3), FOURTH (4) and FIFTH (5) the same way you do for SECOND (2). 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.

6-Speed (VORTEC 8100 V8 and DURAMAXt 6600 V8 Engines)


Here’s how to operate your transmission.


This 6-speed pattern is unique to GM manual transmissions. The transmission always repositions the shift lever to NEUTRAL, which is located between FOURTH (4) and FIFTH (5) gear. To prevent unintentional gear selections, additional force is required to move the shift lever into REVERSE (R) or FIRST (1). Use FIRST (1) when trailer towing, driving with payload in the pickup box or launching on a grade. Otherwise, start in SECOND (2) gear. Only shift into FIRST (1) when the vehicle has stopped moving.


During the first 500 miles (805 km) of vehicle use, start the vehicle moving in FIRST (1) gear. This allows the clutch components to wear-in properly. FIRST (1): With the vehicle at a stop, release the brake, press the clutch pedal and shift into FIRST (1). Then, slowly let up on the clutch pedal as you press the accelerator pedal. Only downshift into FIRST (1) when the vehicle has come to a complete stop. If the shift lever will not go into FIRST (1), put the lever in NEUTRAL and let up on the clutch pedal to fully engage the clutch. Press the clutch pedal again. Then, shift into FIRST (1). SECOND (2): With the vehicle at a stop, release the brake, press the clutch pedal and shift into SECOND (2). Then, slowly let up on the clutch pedal as you press the accelerator pedal. With the vehicle moving, press the clutch pedal and upshift into SECOND (2) from FIRST (1) while applying light pressure to the right on the shifter. Then, slowly let up on the clutch pedal as you press the accelerator pedal. If you come to a complete stop and the shift lever will not go into SECOND (2), put the lever in NEUTRAL and let up on the clutch pedal to fully engage the clutch. Press the clutch pedal again. Then, shift into SECOND (2).


2-31


THIRD (3): Press the clutch pedal and upshift into THIRD (3). Then, slowly let up on the clutch pedal as you press the accelerator pedal. FOURTH (4), FIFTH (5) and SIXTH (6): Upshift into the higher forward gears the same way as you do THIRD (3). Slowly let up on the clutch pedal as you press the accelerator pedal. NEUTRAL: Use this position when you start or idle your engine. REVERSE (R): To back up, press the clutch pedal. Wait for the vehicle to stop moving and then, shift to REVERSE (R). Let up on the clutch slowly while pressing the accelerator pedal. Also, use REVERSE (R), along with the parking brake, when turning off your engine and parking your vehicle.


Shift Speeds


CAUTION:


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


Do not allow the engine rpm to overspeed and enter the tachometer red lines. Engine overspeed occurs when downshifting, or descending a grade, at too high a vehicle speed. When going down steep grades, always select a gear at least one position lower than you would use on climbing a grade. This will allow the vehicle’s engine to provide some braking and help to slow the vehicle as it goes down the grade. Monitor your vehicle speed, acceleration and engine rpm while applying the brakes as you go down the grade to ensure you have complete control over the vehicle.


2-32


If your engine speed drops below 600 rpm, or if the engine is not running smoothly, you should downshift to the next lower gear. When operating on slippery surfaces, downshift at lower than normal vehicle speeds to prevent the tires from slipping. In bench seat equipped vehicles, move the tallest beverage containers to the right cupholder to provide additional clearance for the shift lever. For vehicles equipped with a center console, the front cup holder pulls out and turns 180_ to provide additional clearance between tall beverage containers and the shift lever.


Shift Light


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 allow. 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. If your vehicle has four-wheel drive and is equipped with a manual transmission, disregard the SHIFT light when the transfer case is in 4-Wheel Low. Ignore the SHIFT light when you downshift.


2-33


Four-Wheel Drive (If Equipped) 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 part that follows before using four-wheel drive. See the appropriate text for the transfer case in your vehicle.


NOTICE:


Driving in the 4-WHEEL HIGH (4HI) or 4-WHEEL LOW (4LO) positions for a long time on dry or wet pavement could shorten the life of your vehicle’s drivetrain.


Front Axle Locking Feature The front axle locks and unlocks automatically when you shift the transfer case. Some delay for the axle to lock or unlock is normal.


2-34


Manual Transfer Case (If Equipped)


The transfer case shift lever is on the floor to the right of the driver. Use this lever to shift into and out of four-wheel drive.


The 4WD indicator will light up when you shift into four-wheel drive and the front axle engages.


Some delay between shifting and the indicator’s lighting is normal.


CAUTION:


Shifting the transfer case to NEUTRAL can cause your vehicle to roll even if the transmission is in PARK (P), or if you have a manual transmission, even if you are in gear. You or someone else could be seriously injured. Be sure to set the parking brake before placing the transfer case in NEUTRAL. See “Parking Brake” in the Index.


NEUTRAL (N): Shift to this setting only when your vehicle needs to be towed. The ignition switch must be in RUN in order to shift the lever into NEUTRAL (N). See “Recreational Vehicle Towing” or “Towing your Vehicle” in the Index. 4-Wheel Low (4L0): This setting also engages your front axle and delivers extra torque. You may never need 4LO. It sends maximum power to all four wheels. You might choose 4LO if you are driving off-road in deep sand, deep mud, deep snow and climbing or descending steep hills.


2-35


An indicator on the bezel near the lever shows you the transfer case settings: 2-Wheel High (2HI): This setting is used for driving in most street and highway situations. Your front axle is not engaged in two-wheel drive. This setting also provides the best fuel economy. 4-Wheel High (4HI): Use 4HI when you need extra traction, such as on snowy or icy roads or in most off-road situations. This setting also engages your front axle to help drive your vehicle. This is the best setting to use when plowing snow.


Automatic Transfer Case (If Equipped)


The transfer case switches are located to the left of the instrument panel cluster.


Use these switches to shift into and out of four-wheel drive.


You can shift from 2-Wheel High (2HI) to 4-Wheel High (4HI) or from 4-Wheel High (4HI) to 2-Wheel High (2HI) while the vehicle is moving. Your front axle will engage faster if you take your foot off of the accelerator for a couple of seconds after you shift. In extremely cold weather, it may be necessary to stop or slow the vehicle to shift into 4-Wheel High (4HI). To shift into or out of 4-Wheel Low (4LO) or NEUTRAL (N): 1. Slow the vehicle to a roll, about 1 to 3 mph


(2 to 5 km/h) and shift an automatic transmission into NEUTRAL (N), or with a manual transmission, press the clutch pedal.


2. Shift the transfer case shift lever in


one continuous motion.


Don’t pause in NEUTRAL (N) as you shift the transfer case into 4-Wheel Low (4LO), or your gears could clash. Remember that driving in 4-Wheel High (4HI) or 4-Wheel Low (4LO) may reduce fuel economy. Also, driving in four-wheel drive on dry pavement could cause your tires to wear faster and make your transfer case harder to shift and run noisier.


2-36


4HI: Use 4HI when you need extra traction, such as on snowy or icy roads or in most off-road situations. This setting also engages your front axle to help drive your vehicle. This is the best setting to use when plowing snow. 4LO: This setting also engages your front axle and delivers extra torque. You may never need 4LO. It sends maximum power to all four wheels. You might choose 4LO if you are driving off-road in deep sand, deep mud, deep snow and climbing or descending steep hills.


CAUTION:


Shifting the transfer case to NEUTRAL can cause your vehicle to roll even if the transmission is in PARK (P). You or someone else could be seriously injured. Be sure to set the parking brake before placing the transfer case in NEUTRAL. See “Parking Brake” in the Index.


NEUTRAL: Shift the vehicle’s transfer case to NEUTRAL only when towing your vehicle. See “Recreational Vehicle Towing” or “Towing Your Vehicle” in the Index for more information.


2-37


You can choose among four driving settings: 2HI: This setting is used for driving in most street and highway situations. Your front axle is not engaged in two-wheel drive. This setting also provides the best fuel economy. AUTO 4WD: This setting is ideal for use when road conditions are variable. When driving your vehicle in AUTO 4WD, the front axle is engaged, but the vehicle’s power is sent to the rear wheels. When the vehicle senses a loss of traction, the system will automatically engage four-wheel drive. Driving in this mode results in slightly lower fuel economy than 2HI.


Indicator lights in the switches show which setting your transfer case is in. The indicator lights will come on briefly when you turn on the ignition and one will stay on. If the lights do not come on, you should take your vehicle to your dealer for service. An indicator light will flash while the transfer case is being shifted. It will remain illuminated when the shift is complete. If for some reason the transfer case cannot make a requested shift, it will return to the last chosen setting. If the SERVICE 4WD light stays on, you should take your vehicle to your dealer for service. See “Service 4WD” in the Index for further information.


Shifting to 4HI or AUTO 4WD Press and release the 4HI or AUTO 4WD switch. This can be done at any speed (except when shifting from 4LO), and the indicator light will flash while shifting. It will remain illuminated when the shift is completed.


Shifting to 2HI Press and release the 2HI switch. This can be done at any speed (except when shifting from 4LO).


Shifting to 4LO To shift to 4LO, the ignition must be in RUN and the vehicle must be stopped or moving less than 3 mph (4.8 km/h) with the transmission in NEUTRAL (N). The preferred method for shifting into 4LO is to have your vehicle moving 1 to 2 mph (1.6 to 3.2 km/h). Press and release the 4LO switch. You must wait for the 4LO indicator light to stop flashing and remain illuminated before shifting your transmission in gear. If the 4LO switch is pressed when your vehicle is in gear and/or moving, the 4LO indicator light will flash for 30 seconds and not complete the shift unless your vehicle is moving less than 3 mph (4.8 km/h) and the transmission is in NEUTRAL (N). After 30 seconds the transfer case will return to the setting last chosen.


Shifting Out of 4LO To shift from 4LO to 4HI, AUTO 4WD or 2HI your vehicle must be stopped or moving less than 3 mph (4.8 km/h) with the transmission in NEUTRAL (N) and the ignition in RUN. The preferred method for shifting out of 4LO is to have your vehicle moving 1 to 2 mph (1.6 to 3.2 km/h). Press and release the 4HI, AUTO 4WD or 2HI switch. You must wait for the 4HI, AUTO 4WD or 2HI indicator light to stop flashing and remain illuminated before shifting your transmission into gear.


2-38


If the 4HI, AUTO 4WD or 2HI switch is pressed when your vehicle is in gear and/or moving, the 4HI, AUTO 4WD or 2HI indicator light will flash for 30 seconds but will not complete the shift unless your vehicle is moving less than 3 mph (4.8 km/h) and the transmission is in NEUTRAL (N).


Shifting to NEUTRAL To shift the transfer case to NEUTRAL, first make sure the vehicle is parked so that it will not roll: 1. Set the parking brake. 2. Start the vehicle or turn the ignition to RUN. 3. Connect the vehicle to the towing vehicle. 4. Put the transmission in NEUTRAL (N). 5. Shift the transfer case to 2HI. 6. Simultaneously press and hold the 2HI and 4LO buttons for 10 seconds. The red NEUTRAL light will come on when the transfer case shift to NEUTRAL is complete.


7. Shift the transmission to REVERSE (R) for one


second, then shift the transmission to DRIVE (D) for one second.


8. Turn the ignition to OFF. 9. Place the transmission shift lever in PARK (P). 10. Release the parking brake prior to towing.


Shifting Out of NEUTRAL To shift out of NEUTRAL: 1. Set the parking brake and apply the regular


brake pedal.


2. Shift the transmission to NEUTRAL (N) and turn the


ignition to RUN with the engine off.


3. Press the button for the desired transfer case shift


position (2HI, 4HI, AUTO 4WD or 4LO).


4. After the transfer case has shifted out of NEUTRAL


the red light will go out.


5. You may start the engine and shift the transmission


to the desired position.


2-39


Electronic Transfer Case (If Equipped) If your four-wheel-drive vehicle has the electronic transfer case, the transfer case switches are located to the left of the instrument panel cluster. Use these switches to shift into and out of four-wheel drive. You can choose among three driving settings:


2HI: This setting is for driving in most street and highway situations. Your front axle is not engaged in two-wheel drive. 4HI: This setting engages your front axle to help drive your vehicle. Use 4HI when you need extra traction, such as on snowy or icy roads, or in most off-road situations. 4LO: This setting also engages your front axle to give you extra traction. You may never need 4LO. It sends the maximum power to all four wheels. You might choose 4LO if you were driving off-road in sand, mud or deep snow and climbing or descending steep hills. Indicator lights in the switches show you which setting you are in. The indicator lights will come on briefly when you turn on the ignition and the last chosen setting will stay on. If the lights do not come on, you should take your vehicle in for service. An indicator light will flash while shifting. It will remain illuminated when the shift is completed. If for some reason the transfer cannot make a requested shift, it will return to the last chosen setting.

Shifting from 2HI to 4HI Press and release the 4HI switch. This can be done at any speed, and the front axle will lock automatically with some delay.


Shifting from 4HI to 2HI Press and release the 2HI switch. This can be done at any speed, and the front axle will unlock automatically with some delay.


Shifting from 2HI or 4HI to 4LO To shift from 2HI or 4HI to 4LO, the vehicle must be stopped or moving less than 3 mph (4.8 km/h) with the transmission in NEUTRAL (N). The preferred method for shifting into 4LO is to have your vehicle moving 1 to 2 mph (1.6 to 3.2 km/h). Press and release the 4LO switch. You must wait for the 4LO indicator light to stop flashing and remain illuminated before shifting your transmission into gear.


If the 4LO switch is pressed when your vehicle is in gear and/or moving, the 4LO indicator light will flash for 30 seconds and not complete the shift unless your vehicle is moving slower than 3 mph (4.8 km/h) and the transmission is in NEUTRAL (N). The transfer case will shift to 4HI while waiting to complete the shift to 4LO if you are shifting from 2HI.
