Vehicle Data Recording and Privacy Your GM vehicle has a number of sophisticated computers that record information about the vehicle’s performance and how it is driven. For example, your vehicle uses computer modules to monitor and control engine and transmission performance, to monitor the conditions for airbag deployment and deploy airbags in a crash and, if so equipped, to provide antilock braking to help the driver control the vehicle. These modules may store data to help your dealer/retailer technician service your vehicle. Some modules may also store data about how you operate the vehicle, such as rate of fuel consumption or average speed. These modules may also retain the owner’s personal preferences, such as radio pre-sets, seat positions, and temperature settings. 7-16 Event Data Recorders This vehicle has an Event Data Recorder (EDR). The main purpose of an EDR is to record, in certain crash or near crash-like situations, such as an airbag deployment or hitting a road obstacle, data that will assist in understanding how a vehicle’s systems performed. The EDR is designed to record data related to vehicle dynamics and safety systems for a short period of time, typically 30 seconds or less. The EDR in this vehicle is designed to record such data as: (cid:127) How various systems in your vehicle were operating (cid:127) Whether or not the driver and passenger safety belts were buckled/fastened (cid:127) How far, if at all, the driver was pressing the accelerator and/or brake pedal (cid:127) How fast the vehicle was traveling This data can help provide a better understanding of the circumstances in which crashes and injuries occur. Important: EDR data is recorded by your vehicle only if a non-trivial crash situation occurs; no data is recorded by the EDR under normal driving conditions and no personal data (e.g., name, gender, age, and crash location) is recorded. However, other parties, such as law enforcement, could combine the EDR data with the type of personally identifying data routinely acquired during a crash investigation. To read data recorded by an EDR, special equipment is required, and access to the vehicle or the EDR is needed. In addition to the vehicle manufacturer, other parties, such as law enforcement, that have the special equipment, can read the information if they have access to the vehicle or the EDR. GM will not access this data or share it with others except: with the consent of the vehicle owner or, if the vehicle is leased, with the consent of the lessee; in response to an official request of police or similar government office; as part of GM’s defense of litigation through the discovery process; or, as required by law. Data that GM collects or receives may also be used for GM research needs or may be made available to others for research purposes, where a need is shown and the data is not tied to a speciﬁc vehicle or vehicle owner. 7-17 OnStar® If your vehicle has OnStar and you subscribe to the OnStar services, please refer to the OnStar Terms and Conditions for information on data collection and use. See also OnStar® System on page 2-67 in this manual for more information. Navigation System If your vehicle has a navigation system, use of the system may result in the storage of destinations, addresses, telephone numbers, and other trip information. Refer to the navigation system operating manual for information on stored data and for deletion instructions. Radio Frequency Identiﬁcation (RFID) RFID technology is used in some vehicles for functions such as tire pressure monitoring and ignition system security, as well as in connection with conveniences such as key fobs for remote door locking/unlocking and starting, and in-vehicle transmitters for garage door openers. RFID technology in GM vehicles does not use or record personal information or link with any other GM system containing personal information. 7-18 A Accessories and Modiﬁcations

For programming information, see DIC Vehicle Customization (With DIC Buttons) on page 3-76. 1-7 Reclining Seatbacks {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 do not want to. Adjust the driver’s seat only when the vehicle is not moving. {CAUTION: If the seatback is not locked, it could move forward in a sudden stop or crash. That could cause injury to the person sitting there. Always push and pull on the seatback to be sure it is locked. 1-8 {CAUTION: Sitting in a reclined position when your vehicle is in motion can be dangerous. Even if you buckle up, your safety belts cannot do their job when you are reclined like this. The shoulder belt cannot do its job. In a crash, you could go into it, receiving neck or other injuries. The lap belt cannot 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. Manual Reclining Seatbacks On seats with manual reclining seatbacks, the lever used to operate them is located on the outboard side of the seat(s). To recline the seatback: 1. Lift the recline lever. 2. Move the seatback to the desired position, then release the lever to lock the seatback in place. 3. Push and pull on the seatback to make sure it is locked. 1-9 To return the seatback to an upright position, do the following: 1. Lift the lever fully without applying pressure to the seatback and the seatback will return to the upright position. 2. Push and pull on the seatback to make sure it is locked. Power Reclining Seatbacks If the seats have power reclining seatbacks, the control used to recline them is located on the outboard side of the seat behind the power seat control. (cid:127) To recline the seatback, tilt the top of the control rearward. (cid:127) To bring the seatback forward, tilt the top of the control forward. Do not have a seatback reclined if your vehicle is moving. 1-10 Head Restraints Adjust the head restraint so that the top of the restraint is at the same height as the top of the occupant’s head. This position reduces the chance of a neck injury in a crash. Pull the head restraint up to raise it. To lower the head restraint, press the release button, located on the top of the seatback, while you push the head restraint down. The second row seats have head rests that can be adjusted up and down. 1-11 Seatback Latches The front seatbacks tilt forward to allow access to the rear of the cab. To tilt the seatback forward, lift the lever located on the outboard side of the seat cushion. {CAUTION: If the seatback is not locked, it could move forward in a sudden stop or crash. That could cause injury to the person sitting there. Always push and pull on the seatback to be sure it is locked. To return the seatback to the upright position, push the seatback rearward until it latches. After returning the seatback to its upright position, push and pull on the seatback to make sure it is locked. Center Seat Your vehicle may have a front center seat. The seatback doubles as an armrest and cupholder/storage area for the driver and passenger when the center seat is not used. Do not use it as a seating position when the seatback is folded down. 1-12 Rear Seats Rear Seat Operation (Full Bench) Folding the Rear Seat To fold the seat up, do the following: Notice: Folding a rear seat with the safety belts still fastened may cause damage to the seat or the safety belts. Always unbuckle the safety belts and return them to their normal stowed position before folding a rear seat. 1. Pull up on the front of the seat cushion while pulling down on the release strap, located under the seat cushion. 2. Pull the seat cushion up until it latches with the seatback. 3. After latching the seat cushion up, pull forward on it to make sure it is locked. To fold the seat down, do the following: 1. Push the seat cushion rearward while pulling the release strap, located under the seat cushion. Pull the seat cushion down until it latches. 2. After latching the seat cushion, pull up on it to make sure it is locked. Rear Seat Operation (Split Bench) Folding Rear Seat On a vehicle with a second row 60/40 split seat either side of the rear seat may be folded for added cargo space. Notice: Folding a rear seat with the safety belts still fastened may cause damage to the seat or the safety belts. Always unbuckle the safety belts and return them to their normal stowed position before folding a rear seat. Make sure that nothing is on the seat. To fold the seat, slowly pull the seat cushion up. To return the seat to the normal seating position, slowly pull the seat cushion down. {CAUTION: A safety belt that is improperly routed, not properly attached, or twisted will not provide the protection needed in a crash. The person wearing the belt could be seriously injured. After raising the rear seatback, always check to be sure that the safety belts are properly routed and attached, and are not twisted. 1-13 Safety Belts Safety Belts: They Are for Everyone This part of the manual tells you how to use safety belts properly. It also tells you some things you should not do with safety belts. {CAUTION: Do not let anyone ride where he or she cannot wear a safety belt properly. If you are in a crash and you are not wearing a safety belt, your injuries can be much worse. You can hit things inside the vehicle harder or be ejected from it and 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 passenger(s) are restrained properly too. 1-14 {CAUTION: People riding on the tailgate (if equipped) can easily lose their balance and fall even when the vehicle is operated at low speeds. Falling from a moving vehicle may result in serious injuries or death. {CAUTION: It is extremely dangerous to ride in a cargo area, inside or outside of a vehicle. In a collision, people riding in these areas are more likely to be seriously injured or killed. Do not allow people to ride in any area of your vehicle that is not equipped with seats and safety belts. Be sure everyone in your vehicle is in a seat and using a safety belt properly. Your vehicle has indicators as a reminder to buckle your safety belts. See Safety Belt Reminders on page 3-39. Why Safety Belts Work When you ride in or on anything, you go as fast as it goes. In most states and in all Canadian provinces, the law requires wearing safety belts. Here is why: You never know if you will be in a crash. If you do have a crash, you do not know if it will be a serious one. A few crashes are mild, and some crashes can be so serious that even buckled up, a person would not 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 40 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 is just a seat on wheels. 1-15 Put someone on it. Get it up to speed. Then stop the vehicle. The rider does not stop. 1-16 The person keeps going until stopped by something. In a real vehicle, it could be the windshield... or the instrument panel... 1-17 Questions and Answers About Safety Belts Q: Will I be trapped in the vehicle after a crash if I am wearing a safety belt? A: You could be — whether you are wearing a safety belt or not. But your chance of being conscious during and after an accident, so you can unbuckle and get out, is much greater if you are belted. And you can unbuckle a safety belt, even if you are upside down. Q: If my vehicle has airbags, why should I have to wear safety belts? A: Airbags are supplemental systems only; so they work with safety belts — not instead of them. Whether or not an airbag is provided, all occupants still have to buckle up to get the most protection. That is 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 is why safety belts make such good sense. 1-18 Q: If I am a good driver, and I never drive far from home, why should I wear safety belts? A: You may be an excellent driver, but if you are in a crash — even one that is not your fault — you and your passenger(s) can be hurt. Being a good driver does not protect you from things beyond your control, such as bad drivers. Most accidents occur within 25 miles (40 km) of home. And the greatest number of serious injuries and deaths occur at speeds of less than 40 mph (65 km/h). Safety belts are for everyone. How to Wear Safety Belts Properly This section 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 Older Children on page 1-35 or Infants and Young Children on page 1-39. Follow those rules for everyone’s protection. It is very important for all occupants to buckle up. Statistics show that unbelted people are hurt more often in crashes than those who are wearing safety belts. Occupants who are not buckled up can be thrown out of the vehicle in a crash. And they can strike others in the vehicle who are wearing safety belts. First, before you or your passenger(s) wear a safety belt, there is important information you should know. 1-19 Sit up straight and always keep your feet on the ﬂoor in front of you. The lap part of the belt should be worn low and snug on the hips, just touching the thighs. In a crash, this applies force to the strong pelvic bones and you would be less likely to slide under the lap belt. If you slid under it, the belt would apply force on 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 shoulder belt locks if there is a sudden stop or crash. 1-20 Q: What is wrong with this? {CAUTION: You can be seriously hurt if your shoulder belt is too loose. In a crash, you would move forward too much, which could increase injury. The shoulder belt should ﬁt snugly against your body. A: The shoulder belt is too loose. It will not give as much protection this way. 1-21 Q: What is wrong with this? {CAUTION: You can be seriously hurt if your lap belt is too loose. In a crash, you could slide under the lap belt and apply force on your abdomen. This could cause serious or even fatal injuries. The lap belt should be worn low and snug on the hips, just touching the thighs. A: The lap belt is too loose. It will not give nearly as much protection this way. 1-22 Q: What is wrong with this? {CAUTION: You can be seriously injured if your belt is buckled in the wrong place like this. In a crash, the belt would go up over your abdomen. The belt forces would be there, not on the pelvic bones. This could cause serious internal injuries. Always buckle your belt into the buckle nearest you. A: The belt is buckled in the wrong place. 1-23 {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 on the abdomen, not on the pelvic bones, and that could cause serious or fatal injuries. Be sure the belt goes under the armrests. Q: What is wrong with this? A: The belt is over an armrest. 1-24 Q: What is wrong with this? A: The shoulder belt is worn under the arm. It should be worn over the shoulder at all times. {CAUTION: You can be seriously injured if you wear the shoulder belt under your arm. In a crash, your body would move too far forward, which would increase the chance of head and neck injury. Also, the belt would apply too much force to the ribs, which are not as strong as shoulder bones. You could also severely injure internal organs like your liver or spleen. The shoulder belt should go over the shoulder and across the chest. 1-25 {CAUTION: You can be seriously injured by not wearing the lap-shoulder belt properly. In a crash, you would not be restrained by the shoulder belt. Your body could move too far forward increasing the chance of head and neck injury. You might also slide under the lap belt. The belt force would then be applied right on the abdomen. That could cause serious or fatal injuries. The shoulder belt should go over the shoulder and across the chest. Q: What is wrong with this? A: The belt is behind the body. 1-26 Q: What is wrong with this? {CAUTION: You can be seriously injured by a twisted belt. In a crash, you would not 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/retailer to ﬁx it. A: The belt is twisted across the body. 1-27 Lap-Shoulder Belt All seating positions in your vehicle have a lap-shoulder belt except for the center front passenger position (if equipped) if your vehicle is a crew or extended cab, which has a lap belt. See Lap Belt (Crew and Extended Cab) on page 1-34 for more information. Here is how to wear a lap-shoulder belt properly. 1. Adjust the seat, if the seat is adjustable, so you can sit up straight. To see how, see “Seats” in the Index. 2. Pick up the latch plate and pull the belt across you. Do not let it get twisted. The lap-shoulder belt may lock if you pull the belt across you very quickly. If this happens, let the belt go back slightly to unlock it. Then pull the belt across you more slowly. If you ever pull the shoulder portion of a passenger belt out all the way, you may engage the child restraint locking feature. If this happens, just let the belt go back all the way and start again. Engaging the child restraint locking feature may affect the passenger sensing system. See Passenger Sensing System on page 1-81. 1-28 3. 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 is not long enough, see Safety Belt Extender on page 1-35. Make sure the release button on the buckle is positioned so you would be able to unbuckle the safety belt quickly if necessary. 4. If equipped with a shoulder belt height adjuster, move it to the height that is right for you. Improper shoulder belt height adjustment could reduce the effectiveness of the safety belt in a crash. See “Shoulder Belt Height Adjustment” later in this section. 5. To make the lap part tight, pull up on the shoulder belt. It may be necessary to pull stitching on the safety belt through the latch plate to fully tighten the lap belt on smaller occupants. To unlatch the belt, just push the button on the buckle. Before you close a door, be sure the belt is out of the way. If you slam the door on it, you can damage both the belt and your vehicle. 1-29 Shoulder Belt Height Adjuster Your vehicle has a shoulder belt height adjuster for the driver and right front passenger. 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. Improper shoulder belt height adjustment could reduce the effectiveness of the safety belt in a crash. On the extended cabs, push down on the release button (A) and move the height adjuster to the desired position. To move the adjuster down for the regular and crew cabs, squeeze the buttons (A) on the sides of the height adjuster and move the height adjuster to the desired position. Extended Cab 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 squeezing the buttons for the regular and crew cabs, or without pushing the release button for extended cabs, to make sure it has locked into position. Regular and Crew Cab 1-30 Safety Belt Pretensioners Your vehicle has safety belt pretensioners for front outboard occupants. Although you cannot see them, they are part of the safety belt assembly. They can help tighten the safety belts during the early stages of a moderate to severe frontal, near frontal, or rear crash if the threshold conditions for pretensioner activation are met. And, if your vehicle has side impact airbags, safety belt pretensioners can help tighten the safety belts in a side crash or a rollover event. Pretensioners work only once. If they activate in a crash, you will need to get new ones, and probably other new parts for your safety belt system. See Replacing Restraint System Parts After a Crash on page 1-89. Rear Safety Belt Comfort Guides Rear shoulder belt comfort guides may provide added safety belt comfort for older children who have outgrown booster seats and for some adults. When installed on a shoulder belt, the comfort guide positions the belt away from the neck and head. There is one guide for each outboard passenger position in the rear seat. Here is how to install a comfort guide to the shoulder belt: 1. Remove the guide from its storage clip on the interior body. 2. Place the guide over the belt and insert the two edges of the belt into the slots of the guide. 1-31 {CAUTION: A safety belt that is not properly worn may not provide the protection needed in a crash. The person wearing the belt could be seriously injured. 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. 3. Be sure that the belt is not twisted and it lies ﬂat. The elastic cord must be under the belt and the guide on top. 1-32 Safety Belt Use During Pregnancy Safety belts work for everyone, including pregnant women. Like all occupants, they are more likely to be seriously injured if they do not wear safety belts. 4. Buckle, position, and release the safety belt as described previously in this section. Make sure that the shoulder belt crosses the shoulder. To remove and store the comfort guide, squeeze the belt edges together so that you can take them out of the guides. Slide the guide onto the storage clip. 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 is more likely that the fetus will not be hurt in a crash. For pregnant women, as for anyone, the key to making safety belts effective is wearing them properly. 1-33 Lap Belt (Crew and Extended Cab) This part is only for the lap belt. To learn how to wear a lap-shoulder belt, see Lap-Shoulder Belt on page 1-28. You vehicle may have a center seating position. When you sit in the center front seating position, you have a lap safety belt, which has no retractor. To make the belt longer, tilt the latch plate and pull it along the belt. 1-34 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 is not long enough, see Safety Belt Extender on page 1-35. Make sure the release button on the buckle is positioned so you would be able to unbuckle the safety belt quickly if necessary. Child Restraints Older Children Safety Belt Extender If the safety belt will fasten around you, you should use it. But if a safety belt is not long enough, your dealer/ retailer will order you an extender. When you go in to order it, take the heaviest coat you will wear, so the extender will be long enough for you. To help avoid personal injury, do not let someone else use it, and use it only for the seat it is made to ﬁt. The extender has been designed for adults. Never use it for securing child seats. To wear it, attach it to the regular safety belt. For more information, see the instruction sheet that comes with the extender. Older children who have outgrown booster seats should wear the vehicle’s safety belts. 1-35 The manufacturer’s instructions that come with the booster seat state the weight and height limitations for that booster. Use a booster seat with a lap-shoulder belt until the child passes the below ﬁt test: (cid:127) Sit all the way back on the seat. Do the knees bend at the seat edge? If yes, continue. If no, return to the booster seat. (cid:127) Buckle the lap-shoulder belt. Does the shoulder belt rest on the shoulder? If yes, continue. If no, try using the rear safety belt comfort guide. See “Rear Safety Belt Comfort Guides” under Lap-Shoulder Belt on page 1-28 for more information. If the shoulder belt still does not rest on the shoulder, then return to the booster seat. (cid:127) Does the lap belt ﬁt low and snug on the hips, touching the thighs? If yes, continue. If no, return to the booster seat. (cid:127) Can proper safety belt ﬁt be maintained for the length of the trip? If yes, continue. If no, return to the booster seat. Q: What is the proper way to wear safety belts? A: 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. This applies belt force to the child’s pelvic bones in a crash. It should never be worn over the abdomen, which could cause severe or even fatal internal injuries in a crash. Also see “Rear Safety Belt Comfort Guides” under Lap-Shoulder Belt on page 1-28. According to accident statistics, children and infants are safer when properly restrained in the rear seating positions than in the front seating positions. 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. 1-36 {CAUTION: Never do this. Here two children are wearing the same belt. The belt cannot 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. 1-37 {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. In a crash, the child would not be restrained by the shoulder belt. The child might slide under the lap belt. The belt force would then be applied right on the abdomen. That could cause serious or fatal injuries. The child could also move too far forward increasing the chance of head and neck injury. The shoulder belt should go over the shoulder and across the chest. 1-38 {CAUTION: People should never hold an infant in their arms while riding in a vehicle. An infant does not weigh much — until a crash. During a crash an infant will become so heavy it is not possible to hold it. For example, in a crash at only 25 mph (40 km/h), a 12 lb (5.5 kg) infant will suddenly become a 240 lb (110 kg) force on a person’s arms. An infant should be secured in an appropriate restraint. Infants and Young Children Everyone in a vehicle needs protection! This includes infants and all other children. Neither the distance traveled nor the age and size of the traveler changes the need, for everyone, to use safety restraints. In fact, the law in every state in the United States and in every Canadian province says children up to some age must be restrained while in a vehicle. {CAUTION: Children can be seriously injured or strangled if a shoulder belt is wrapped around their neck and the safety belt continues to tighten. Never leave children unattended in a vehicle and never allow children to play with the safety belts. Every time infants and young children ride in vehicles, they should have the protection provided by appropriate restraints. Children who are not restrained properly can strike other people, or can be thrown out of the vehicle. In addition, young children should not use the vehicle’s adult safety belts alone; they need to use a child restraint. 1-39 {CAUTION: Children who are up against, or very close to, any airbag when it inﬂates can be seriously injured or killed. Airbags plus lap-shoulder belts offer protection for adults and older children, but not for young children and infants. Neither the vehicle’s safety belt system nor its airbag system is designed for them. Young children and infants need the protection that a child restraint system can provide. 1-40 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. {CAUTION: The body structure of a young child is quite unlike that of an adult or older child, for whom the safety belts are designed. A young child’s hip bones are still so small that the vehicle’s regular safety belt may not remain low on the hip bones, as it should. Instead, it may settle up around the child’s abdomen. In a crash, the belt would apply force on a body area that is unprotected by any bony structure. This alone could cause serious or fatal injuries. Young children should always be secured in appropriate child restraints. For most basic types of child restraints, there are many different models available. When purchasing a child restraint, be sure it is designed to be used in a motor vehicle. If it is, the restraint will have a label saying that it meets federal motor vehicle safety standards. The restraint manufacturer’s instructions that come with the restraint state the weight and height limitations for a particular child restraint. In addition, there are many kinds of restraints available for children with special needs. {CAUTION:
