kept for an overnight warranty repair. Rental reimbursement will be limited and must be supported by original receipts. This requires that you sign and complete a rental agreement and meet state/provincial, local, and rental vehicle provider requirements. Requirements vary and may include minimum age requirements, insurance coverage, credit card, etc. You are responsible for fuel usage charges and may also be responsible for taxes, levies, usage fees, excessive mileage, or rental usage beyond the completion of the repair. Generally it is not possible to provide a like-vehicle as a courtesy rental. 649 Vehicle Data Collection and Event Data Recorders Your vehicle, like other modern motor vehicles, has a number of sophisticated computer systems that monitor and control several aspects of the vehicle’s performance. Your vehicle uses on-board vehicle computers to monitor emission control components to optimize fuel economy, to monitor conditions for airbag deployment and, if the vehicle has the Anti-lock Brake System (ABS), to provide anti-lock braking and to help the driver control the vehicle in difficult driving situations. Some information may be stored during regular operations to facilitate repair of detected malfunctions; other information is stored only in a crash event by computer systems, such as those commonly called Event Data Recorders (EDR). In a crash event, computer systems, such as the airbag Sensing and Diagnostic Module (SDM) in your vehicle may record information about the condition of the vehicle and how it was operated, such as data related to engine speed, brake application, throttle position, vehicle speed, safety belt usage, airbag readiness, airbag performance, 650 and the severity of a collision. This information has been used to improve vehicle crash performance and may be used to improve crash performance of future vehicles and driving safety. Unlike the data recorders on many airplanes, these on-board systems do not record sounds, such as conversation of vehicle occupants. To read this information, special equipment is needed and access to the vehicle or the device that stores the data is required. GM will not access information about a crash event or share it with others other than: (cid:127) 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, (cid:127) (cid:127) as part of GM’s defense of litigation through the discovery process, or (cid:127) as required by law. In addition, once GM collects or receives data, GM may: (cid:127) use the data for GM research needs, (cid:127) make it available for research where appropriate conﬁdentiality is to be maintained and need is shown, or (cid:127) share summary data which is not tied to a speciﬁc vehicle with non-GM organizations for research purposes. Others, such as law enforcement, may have access to the special equipment that can read the information if they have access to the vehicle or the device that stores the data. If your vehicle has OnStar®, please check the OnStar® subscription service agreement or manual for information on its operations and data collection. Collision Damage Repair If your vehicle is involved in a collision and it is damaged, have the damage repaired by a qualiﬁed technician using the proper equipment and quality replacement parts. Poorly performed collision repairs will diminish your vehicle’s resale value, and safety performance can be compromised in subsequent collisions. Collision Parts Genuine GM Collision parts are new parts made with the same materials and construction methods as the parts with which your vehicle was originally built. Genuine GM Collision parts are your best choice to assure that your vehicle’s designed appearance, durability, and safety are preserved. The use of Genuine GM parts can help maintain your GM New Vehicle Warranty. 651 Recycled original equipment parts may also be used for repair. These parts are typically removed from vehicles that were total losses in prior accidents. In most cases, the parts being recycled are from undamaged sections of the vehicle. A recycled original equipment GM part, may be an acceptable choice to maintain your vehicle’s originally designed appearance and safety performance, however, the history of these parts is not known. Such parts are not covered by your GM New Vehicle Limited Warranty, and any related failures are not covered by that warranty. Aftermarket collision parts are also available. These are made by companies other than GM and may not have been tested for your vehicle. As a result, these parts may ﬁt poorly, exhibit premature durability/corrosion problems, and may not perform properly in subsequent collisions. Aftermarket parts are not covered by your GM New Vehicle Limited Warranty, and any vehicle failure related to such parts are not covered by that warranty. 652 Repair Facility GM also recommends that you choose a collision repair facility that meets your needs before you ever need collision repairs. Your GM dealer may have a collision repair center with GM-trained technicians and state of the art equipment, or be able to recommend a collision repair center that has GM-trained technicians and comparable equipment. Insuring Your Vehicle Protect your investment in your GM vehicle with comprehensive and collision insurance coverage. There are signiﬁcant differences in the quality of coverage afforded by various insurance policy terms. Many insurance policies provide reduced protection to your GM vehicle by limiting compensation for damage repairs by using aftermarket collision parts. Some insurance companies will not specify aftermarket collision parts. When purchasing insurance, we recommend that you assure your vehicle will be repaired with GM original equipment collision parts. If such insurance coverage is not available from your current insurance carrier, consider switching to another insurance carrier. If your vehicle is leased, the leasing company may require you to have insurance that assures repairs with Genuine GM Original Equipment Manufacturer (OEM) parts or Genuine Manufacturer replacement parts. Read your lease carefully, as you may be charged at the end of your lease for poor quality repairs. If an Accident Occurs Here is what to do if you are involved in an accident. (cid:127) Try to relax and then check to make sure you (cid:127) are all right. If you are uninjured, make sure that no one else in your vehicle, or the other vehicle, is injured. If there has been an injury, call 911 for help. Do not leave the scene of an accident until all matters have been taken care of. Move your vehicle only if its position puts you in danger or you are instructed to move it by a police officer. (cid:127) Give only the necessary and requested information to police and other parties involved in the accident. Do not discuss your personal condition, mental frame of mind, or anything unrelated to the accident. This will help guard against post-accident legal action. If you need roadside assistance, call GM Roadside Assistance. See Roadside Assistance Program on page 644 for more information. If your vehicle cannot be driven, know where the towing service will be taking it. Get a card from the tow truck operator or write down the driver’s name, the service’s name, and the phone number. (cid:127) (cid:127) (cid:127) Remove any valuables from your vehicle before it is towed away. Make sure this includes your insurance information and registration if you keep these items in your vehicle. 653 (cid:127) Choose a reputable collision repair facility for your vehicle. Whether you select a GM dealer or a private collision repair facility to ﬁx the damage, make sure you are comfortable with them. Remember, you will have to feel comfortable with their work for a long time. (cid:127) Once you have an estimate, read it carefully and make sure you understand what work will be performed on your vehicle. If you have a question, ask for an explanation. Reputable shops welcome this opportunity. (cid:127) Gather the important information you will need from the other driver. Things like name, address, phone number, driver’s license number, vehicle license plate, vehicle make, model and model year, Vehicle Identiﬁcation Number (VIN), insurance company and policy number, and a general description of the damage to the other vehicle. If possible, call your insurance company from the scene of the accident. They will walk you through the information they will need. If they ask for a police report, phone or go to the police department headquarters the next day and you can get a copy of the report for a nominal fee. In some states/provinces with “no fault” insurance laws, a report may not be necessary. This is especially true if there are no injuries and both vehicles are driveable. (cid:127) 654 Managing the Vehicle Damage Repair Process In the event that your vehicle requires damage repairs, GM recommends that you take an active role in its repair. If you have a pre-determined repair facility of choice, take your vehicle there, or have it towed there. Specify to the facility that any required replacement collision parts be original equipment parts, either new Genuine GM parts or recycled original GM parts. Remember, recycled parts will not be covered by your GM vehicle warranty. Insurance pays the bill for the repair, but you must live with the repair. Depending on your policy limits, your insurance company may initially value the repair using aftermarket parts. Discuss this with your repair professional, and insist on Genuine GM parts. Remember if your vehicle is leased you may be obligated to have the vehicle repaired with Genuine GM parts, even if your insurance coverage does not pay the full cost. If another party’s insurance company is paying for the repairs, you are not obligated to accept a repair valuation based on that insurance company’s collision policy repair limits, as you have no contractual limits with that company. In such cases, you can have control of the repair and parts choices as long as cost stays within reasonable limits. 655 Reporting Safety Defects Reporting Safety Defects to the United States Government If you believe that your vehicle has a defect which could cause a crash or could cause injury or death, you should immediately inform the National Highway Traffic Safety Administration (NHTSA), in addition to notifying General Motors. If NHTSA receives similar complaints, it may open an investigation, and if it ﬁnds that a safety defect exists in a group of vehicles, it may order a recall and remedy campaign. However, NHTSA cannot become involved in individual problems between you, your dealer, or General Motors. To contact NHTSA, you may call the Vehicle Safety Hotline toll-free at 1-888-327-4236 (TTY: 1-800-424-9153); go to http://www.safercar.gov; or write to: Administrator, NHTSA 400 Seventh Street, SW.

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. If you need help ﬁguring out a speciﬁc name of a component, gage, or indicator, reference the following topics: (cid:127) Seats and Restraint Systems in Section 1 (cid:127) Features and Controls in Section 2 (cid:127) (cid:127) Climate Controls in Section 3 (cid:127) Warning Lights, Gages, and Indicators in Instrument Panel Overview in Section 3 Section 3 (cid:127) Audio System(s) in Section 3 (cid:127) Engine Compartment Overview in Section 5 These are some examples of symbols that may be found on the vehicle: Section 1 Seats and Restraint Systems Front Seats ..................................................... 9 Manual Seats ................................................ 9 Power Seats ............................................... 10 Power Lumbar ............................................. 11 Heated Seats .............................................. 11 Memory Seat and Mirrors ............................ 12 Reclining Seatbacks .................................... 15 Head Restraints .......................................... 18 Seatback Latches ........................................ 18 Rear Seats .................................................... 19 Rear Seat Operation (Extended Cab) .......... 19 Rear Seat Operation (Crew Cab) ................ 20 Safety Belts .................................................. 22 Safety Belts: They Are for Everyone ........... 22 Questions and Answers About Safety Belts ............................................. 26 How to Wear Safety Belts Properly ............. 27 Driver Position ............................................. 27 Safety Belt Use During Pregnancy .............. 36 Right Front Passenger Position ................... 37 Center Front Passenger Position ................. 37 Rear Seat Passengers ................................ 38 Rear Safety Belt Comfort Guides ................ 41 Safety Belt Extender ................................... 43 Child Restraints ............................................ 44 Older Children ............................................. 44 Infants and Young Children ......................... 47 Child Restraint Systems .............................. 51 Where to Put the Restraint .......................... 55 Lower Anchors and Tethers for Children (LATCH) .................................... 58 Securing a Child Restraint in a Rear Seat Position ........................................... 71 Securing a Child Restraint in the Center Front Seat Position .................................. 74 Securing a Child Restraint in the Right Front Seat Position (Crew Cab) (With Passenger Sensing System) ........... 74 Securing a Child Restraint in the Right Front Seat Position (Regular and Extended Cab) (With Airbag Off Switch) .......................... 78 Securing a Child Restraint in the Right Front Seat Position (Regular and Extended Cab) (With Passenger Sensing System) ...................................... 85 Section 1 Seats and Restraint Systems Passenger Sensing System ....................... 103 Servicing Your Airbag-Equipped Vehicle .... 108 Adding Equipment to Your Airbag-Equipped Vehicle ........................ 109 Restraint System Check ............................. 111 Checking the Restraint Systems ................ 111 Replacing Restraint System Parts After a Crash ......................................... 112 Airbag System .............................................. 91 Where Are the Airbags? .............................. 93 When Should an Airbag Inﬂate? .................. 95 What Makes an Airbag Inﬂate? ................... 97 How Does an Airbag Restrain? ................... 98 What Will You See After an Airbag Inﬂates? ................................................... 98 Airbag Off Switch ...................................... 100 Front Seats Manual Seats {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. If your vehicle has a manual bucket or a split bench seat, you can adjust the seat forward or rearward with the bar located under the front of the seat cushion. Lift the bar to unlock the seat.

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. 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. 15 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 your seats have power reclining seatbacks, use the vertical power seat control located on the outboard side of the seat(s). (cid:127) To recline the seatback, press the control toward the rear of the vehicle. (cid:127) To raise the seatback, press the control toward the front of the vehicle. 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. 17 Head Restraints Adjust the head restraint so that the top of the restraint is at the same height as the occupant’s head. This position reduces the chance of a neck injury in a crash. Pull the head restraint up to raise it. Push the head restraint down to lower it. The rear seats may have head restraints that can be adjusted up and down. 18 Seatback Latches The front seatbacks fold forward to allow access to the rear of the cab. To fold 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. Rear Seats Rear Seat Operation (Extended Cab) Folding the Rear Seat The rear seat in the extended cab can be folded up to provide more cargo space. 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. 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. The seat can also be folded down for more seating space. To fold the seat down, do the following: 1. Push the seat cushion 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. 1. Push down on the front of the seat cushion while pulling down on the release strap, located under the seat cushion. 19 Rear Seat Operation (Crew Cab) The second row seat is a 60/40 split seat. Either side of the rear seat may be ﬂipped and folded for added cargo space. Make sure that nothing is under or in front of the seat and that the head restraints are completely lowered. To ﬂip and fold the seat, do the following: 1. Pull up on the strap loop at the rear of the seat cushion. Then, pull the seat cushion up and ﬂip it forward. 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. 2. After folding the seat cushion fully forward, pull the seatback forward until it is ﬂat. If the seatback cannot fold ﬂat because it interferes with the cushion, try moving the front seat forward and/or bringing the front seat more upright. The lever at the base of the seat must be turned rearward to release the seatback. 20 To return the seat to the normal seating position, do the following: 1. Lift the seatback up and push it rearward all the way. {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. 2. Push and pull on the seatback to make sure it is locked into place. 3. Lower the seat cushion until it latches into position. Pull up on the cushion to make sure it is locked into place. {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. Make sure that the safety belt buckles on the driver’s side seatback are accessible to the outboard and center occupant and are not under the seat cushions. 21 {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. 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 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. 22 Your vehicle has a light that comes on as a reminder to buckle up. See Safety Belt Reminder Light on page 247. 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 says to wear safety belts. Here is why: They work. 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. 23 Put someone on it. Get it up to speed. Then stop the vehicle. The rider does not stop. 24 The person keeps going until stopped by something. In a real vehicle, it could be the windshield... or the instrument panel... 25 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 in many vehicles today and will be in most of them in the future. But they are supplemental systems only; so they work with safety belts — not instead of them. Every 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. 26 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.

If the belt is not long enough, see Safety Belt Extender on page 43. 28 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.
