Allow ample time for delivery. Note to Canadian Customers: All listed prices are quoted in U.S. funds. Canadian residents are to make checks payable in U.S. funds. 536 Event Data Recorders Some information about your vehicle’s performance and how it is driven may be recorded on various modules if a crash occurs. Some people refer to these modules as event data recorders (EDRs). These modules may record several seconds of pre-crash and crash data, such as data related to engine speed, brake application, throttle position, vehicle speed, yaw rate, steering wheel angle, lateral acceleration, safety belt usage, airbag readiness, airbag performance and the severity of the collision. Unlike the ﬂight data recorders on airplanes, these modules do not record sounds or conversations. To retrieve this data, special equipment and access to the vehicle or the module that stores the data are required. Certain data may also be sent to or retrieved by OnStar® (see below). GM will not access this information 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. Others may be able to retrieve this data if they have access to the vehicle and have the special equipment necessary to download the data. 537 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 145 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. Please 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. 538 A Accessories and Modiﬁcations .....................

How to Use This Manual Many people read the owner manual from beginning to end when they ﬁrst receive their new vehicle. If this is done, it can help you learn about the features and controls for the vehicle. Pictures and words work together in the owner manual to explain things. Index A good place to quickly locate information about the vehicle is the Index in the back of the manual. It is an alphabetical list of what is in the manual and the page number where it can be found. Safety Warnings and Symbols There are a number of safety cautions in this book. We use a box and the word CAUTION to tell about things that could hurt you if you were to ignore the warning. {CAUTION: These mean there is something that could hurt you or other people. In the caution area, we tell you what the hazard is. Then we tell you what to do to help avoid or reduce the hazard. Please read these cautions. If you do not, you or others could be hurt. You will also ﬁnd a circle with a slash through it in this book. This safety symbol means “Do Not,” “Do Not do this” or “Do Not let this happen.” Vehicle Damage Warnings Also, in this manual you will ﬁnd these notices: Notice: These mean there is something that could damage your vehicle. A notice tells about something that can damage the vehicle. Many times, this damage would not be covered by your vehicle’s warranty, and it could be costly. But the notice will tell what to do to help avoid the damage. When you read other manuals, you might see CAUTION and NOTICE warnings in different colors or in different words. There are also warning labels on the vehicle. They use the same words, CAUTION or NOTICE. Vehicle Symbols The vehicle has components and labels that use symbols instead of text. Symbols are shown along with the text describing the operation or information relating to a speciﬁc component, control, message, gage, or indicator.

Reclining Seatbacks Manual 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. In vehicles with seats that have manual reclining seatbacks, the lever used to operate them is located on the outboard side of the seat. To recline the seatback, do the following: 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. 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. 15 Power Reclining Seatbacks In vehicles with seats that have power reclining seatbacks, the control used to recline them is located on the outboard side of the seat behind the power seat control. See Power Seats on page 10 for more information. (cid:129) To recline the seatback, tilt the top of the control rearward. (cid:129) To bring the seatback forward, tilt the top of the control forward. 16 {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 because it will not be against your body. Instead, it will be in front of you. In a crash, you could go into it, receiving neck or other injuries. The lap belt 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. Do not have a seatback reclined if your vehicle is moving. Head Restraints 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. 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. 17 Entering and Exiting the Third Row {CAUTION: Using the third row seating position while the second row is folded, or folded and tumbled, could cause injury in a sudden stop or crash. Be sure to return the seat to the passenger seating position. Push and pull on the seat to make sure it is locked into place.

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 or be ejected from it. You can be seriously injured or killed. In the same crash, you might not be, if you are buckled up. Always fasten your safety belt, and check that your passengers’ belts are fastened properly too. {CAUTION: It is extremely dangerous to ride in a cargo area, inside or outside of a vehicle. In a collision, people riding in these areas are more likely to be seriously injured or killed. Do not allow people to ride in any area of your vehicle that is not equipped with seats and safety belts. Be sure everyone in your vehicle is in a seat and using a safety belt properly. Your vehicle has indicators to remind you and your passengers to buckle your safety belts. See Safety Belt Reminder Light on page 216 and Passenger Safety Belt Reminder Light on page 217. In most states and in all Canadian provinces, the law says to wear safety belts. Here is why: They work. 24 Why Safety Belts Work When you ride in or on anything, you go as fast as it goes. 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 bad 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. 25 Put someone on it. Get it up to speed. Then stop the vehicle. The rider does not stop. 26 The person keeps going until stopped by something. In a real vehicle, it could be the windshield... or the instrument panel... 27 Questions and Answers About Safety Belts Q: Will I be trapped in the vehicle after an accident if I am wearing a safety belt? A: You could be — whether you are wearing a safety belt or not. But you can unbuckle a safety belt, even if you are upside down. And your chance of being conscious during and after an accident, so you can unbuckle and get out, is much greater if you are belted. 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. Every airbag system ever offered for sale has required the use of safety belts. Even if you are in a vehicle that has airbags, you 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. 28 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 an accident — even one that is not your fault — you and your passengers 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 part is only for people of adult size. Be aware that there are special things to know about safety belts and children. And there are different rules for smaller children and babies. If a child will be riding in your vehicle, see Older Children on page 48 or Infants and Young Children on page 51. Follow those rules for everyone’s protection. First, you will want to know which restraint systems your vehicle has. We will start with the driver position. 29 Driver Position Lap-Shoulder Belt The driver has a lap-shoulder belt. Here is how to wear it properly. 1. Close and lock the door. 2. Adjust the seat so you can sit up straight. To see how, see “Seats” in the Index. 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. 4. Push the latch plate into the buckle until it clicks. Pull up on the latch plate to make sure it is secure. If the belt is not long enough, see Safety Belt Extender on page 47. Make sure the release button on the buckle is positioned so you would be able to unbuckle the safety belt quickly if you ever had to. 5. Move the shoulder belt height adjuster 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 on page 38. 3. Pick up the latch plate and pull the belt across you. Do not let it get twisted. 30 6. 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. 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 at your abdomen. This could cause serious or even fatal injuries. The shoulder belt should go over the shoulder and across the chest. These parts of the body are best able to take belt restraining forces. The safety belt locks if there is a sudden stop or crash. 31 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 against your body. A: The shoulder belt is too loose. It will not give nearly as much protection this way. 32 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 at 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. 33 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 at 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. 34 Q: What is wrong with this? A: The belt is over an armrest. {CAUTION: You can be seriously injured if your belt goes over an armrest like this. The belt would be much too high. In a crash, you can slide under the belt. The belt force would then be applied at the abdomen, not at the pelvic bones, and that could cause serious or fatal injuries. Be sure the belt goes under the armrests. 35 Q: What is wrong with this? {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. A: The shoulder belt is worn under the arm. It should be worn over the shoulder at all times. 36 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. 37 Shoulder Belt Height Adjustment Before you begin to drive, move the shoulder belt height adjuster to the height that is right for you. 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. Incorrect positioning of the shoulder belt can reduce the effectiveness of the safety belt. To move it down, push down on the button (A) and move the height adjuster to the desired position. You can move the height adjuster up by pushing up on the shoulder belt guide. After you move the height adjuster to where you want it, try to move it down without pushing the button down to make sure it has locked into position. To unlatch the belt, push the button on the buckle. The belt should go back out of the way. When the safety belt is not in use, slide the latch plate up the safety belt webbing. The latch plate should rest on the stitching on the safety belt, near the guide loop on the side wall. Before you close the door, be sure the belt is out of the way. If you slam the door on it, you can damage both the belt and your vehicle. 38 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. 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. Right Front Passenger Position To learn how to wear the right front passenger’s safety belt properly, see Driver Position on page 30. The right front passenger’s safety belt works the same way as the driver’s safety belt — except for one thing. If you ever pull the shoulder portion of the belt out all the way, you will engage the child restraint locking feature. If this happens, let the belt go back all the way and start again. 39 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. Rear Seat Passengers It is very important for rear seat passengers to buckle up! Accident statistics show that unbelted people in the rear seat are hurt more often in crashes than those who are wearing safety belts. Rear passengers who are not safety belted can be thrown out of the vehicle in a crash. And they can strike others in the vehicle who are wearing safety belts. Lap-Shoulder Belt All rear seating positions have lap-shoulder belts. If you are using the center third row seating position and the safety belt is not attached, see Third Row Seats on page 21 for instruction on reconnecting the lap belt to the shoulder belt. Here is how to wear one properly. 40 1. Pick up the latch plate and pull the belt across you. Do not let it get twisted. The 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. 2. Push the latch plate into the buckle until it clicks. Pull up on the latch plate to make sure it is secure. When the shoulder belt is pulled out all the way, it will lock. If it does, let it go back all the way and start again. If the belt is not long enough, see Safety Belt Extender on page 47. Make sure the release button on the buckle is positioned so you would be able to unbuckle the safety belt quickly if you ever had to. 3. To make the lap part tight, pull up on the shoulder part. It may be necessary to pull stitching on the safety belt through the latch plate to fully tighten the lap belt on smaller occupants. 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 at your abdomen. This could cause serious or even fatal injuries. The shoulder belt should go over the shoulder and across the chest. These parts of the body are best able to take belt restraining forces. 41 The safety belt locks if there is a sudden stop or a crash. {CAUTION: You can be seriously hurt if your shoulder belt is too loose. In a crash, you would move forward too much, which could increase injury. The shoulder belt should ﬁt against your body. 42 To unlatch the belt, push the button on the buckle. For outboard seating positions, when the safety belt is not in use, slide the latch plate up the safety belt webbing. The latch plate should rest on the stitching on the safety belt, near the guide loop on the side wall. Here is how to install a comfort guide to the safety belt: 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 a guide for each outboard passenger positions in the second row seat and all passenger positions in the third row. Outboard Positions 1. For the outboard positions, remove the guide from its storage clip on the interior body. 43 For the third row center position, locate the comfort guide which is located in a storage pocket, at the top of the seat, under the headrest on the driver’s side of the vehicle. To access the comfort guide, you will ﬁrst need to move the headrest forward by pulling on the handle behind the seatback. The comfort guide will now be accessible. Pull the comfort guide out of its storage location and then return the headrest to its upright position. The elastic cord on the comfort guide is adjustable. You can make it longer or shorter by squeezing the both ends of the plastic adjuster. Third Row Center Position 44 2. Slide the guide under and past the belt. The elastic cord must be under the belt. Then, place the guide over the belt, and insert the two edges of the belt into the slots of the guide. 3. Be sure that the belt is not twisted and it lies ﬂat. The elastic cord must be under the belt and the guide on top. 45 {CAUTION: A safety belt that is not properly worn may
