These services are provided at a nominal charge if the vehicle is no longer in the Powertrain warranty. Fuel Delivery: Delivery of enough fuel for the vehicle to get to the nearest service station (approximately $5 in Canada). For safety reasons, propane and other alternate fuels will not be provided through this service. Lock-out Service: Lock-out service will be covered at no charge if you are unable to gain entry into your vehicle. A remote unlock may be available if you have an active OnStar® subscription. To ensure security, the driver must present personal identiﬁcation before lock-out service is provided. In Canada, the vehicle registration is also required. (cid:129) Emergency Tow from a Public Roadway or Highway: Tow to the nearest dealership for warranty service or in the event of a vehicle-disabling crash. Flat Tire Change: Installation of a spare tire in good condition, when equipped and properly inﬂated, will be covered at no charge.

Trip Routing Service: Upon request, Roadside Assistance will send you detailed, computer personalized maps, highlighting your choice of either the most direct route or the most scenic route to your destination, anywhere in North America, along with helpful travel information pertaining to your trip. Please allow three weeks before your planned departure date. In Canada, trip routing requests will be limited to six per calendar year. Trip Interruption Beneﬁts and Assistance: If your trip is interrupted due to a warranty failure, incidental expenses may be reimbursed during the 5 years/ 100,000 miles (160 000 km) warranty period. Items covered are hotel, meals, and rental car. HUMMER and General Motors of Canada Limited reserve the right to limit services or reimbursement to an owner or driver when, in their sole discretion, the claims become excessive in frequency or type of occurrence. 7-7 (cid:129) (cid:129) (cid:129) (cid:129) (cid:129) (cid:129) HUMMER Technician Roadside Service (U.S. only) HUMMER’s exceptional Roadside Service is more than an auto club or towing service. It provides every HUMMER owner in the United States with the advantage of contacting a HUMMER advisor and, where available, a HUMMER trained dealer technician who can provide on-site service. A dealer technician will travel to your location generally within a 30 mile radius of a participating HUMMER dealership. If beyond this radius, we will arrange to have your car towed to the nearest HUMMER dealership. Each technician travels with a specially equipped service vehicle complete with the necessary HUMMER parts and tools required to handle most roadside repairs. Calling for Assistance For prompt and efficient assistance when calling, please provide the following to the Roadside Assistance Representative: (cid:129) Your name, home address, and home telephone number Telephone number of your location Location of the vehicle (cid:129) Model, year, color, and license plate number of the vehicle (cid:129) Odometer reading, Vehicle Identiﬁcation Number (VIN), and delivery date of the vehicle (cid:129) Description of the problem Towing and Road Service Exclusions Speciﬁcally excluded from Roadside Service coverage are towing or services for vehicles operated on a non-public roadway or highway, ﬁnes, impound towing caused by a violation of local, Municipal, State, Provincial or Federal law, and mounting, dismounting or changing of snow tires, chains, or other traction devices. Roadside Assistance is not part of or included in the coverage provided by the New Vehicle Limited Warranty. HUMMER and General Motors of Canada Limited reserve the right to make any changes or discontinue the Roadside Assistance program at any time without notiﬁcation. Scheduling Service Appointments When your vehicle requires warranty service, contact your dealer/retailer and request an appointment. By scheduling a service appointment and advising your service consultant of your transportation needs, your dealer/retailer can help minimize your inconvenience. 7-8 (cid:129) (cid:129) If your vehicle cannot be scheduled into the service department immediately, keep driving it until it can be scheduled for service, unless, of course, the problem is safety-related. If it is, please call your dealership/retailer, let them know this, and ask for instructions. If the dealer/retailer requests that you simply drop the vehicle off for service, you are urged to do so as early in the work day as possible to allow for the same day repair. Courtesy Transportation To enhance your ownership experience, we and our participating dealers are proud to offer Courtesy Transportation, a customer support program for vehicles with the Bumper to Bumper (Base Warranty Coverage period in Canada) and extended powertrain warranty in both the U.S. and Canada. Several courtesy transportation options are available to assist in reducing your inconvenience when warranty repairs are required. Courtesy Transportation is not a part of the New Vehicle Limited Warranty. A separate booklet entitled “Warranty and Owner Assistance Information” furnished with each new vehicle provides detailed warranty coverage information. Transportation Options Warranty service can generally be completed while you wait. However, if you are unable to wait, GM helps to minimize your inconvenience by providing several transportation options. Depending on the circumstances, your dealer can offer you one of the following: Shuttle Service Participating dealers can provide shuttle service to get you to your destination with minimal interruption of your daily schedule. This includes one-way or round trip shuttle service to a destination up to 10 miles (16 km) from the dealership. Public Transportation or Fuel Reimbursement If your vehicle requires warranty repairs, and public transportation is used instead of the dealer’s shuttle service, the expense must be supported by original receipts and can only be up to the maximum amount allowed by GM for shuttle service. In addition, for U.S. customers, should you arrange transportation through a friend or relative, limited reimbursement for reasonable fuel expenses may be available. Claim amounts should reﬂect actual costs and be supported by original receipts. See your dealer for information regarding the allowance amounts for reimbursement of fuel or other transportation costs. 7-9 Courtesy Rental Vehicle Your dealer may arrange to provide you with a courtesy rental vehicle or reimburse you for a rental vehicle that you obtain if your vehicle is kept for a warranty repair. If you obtain a rental vehicle on your own, please see your dealer for the maximum number of days allowed and the allowance per rental day. Rental reimbursement must be supported by original receipts. This requires that you sign and complete a rental agreement and meet state, 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. It may not be possible to provide a like-vehicle as a courtesy rental. Additional Program Information All program options, such as shuttle service, may not be available at every dealer. Please contact your dealer for speciﬁc information about availability. All Courtesy Transportation arrangements will be administered by appropriate dealer personnel. General Motors reserves the right to unilaterally modify, change, or discontinue Courtesy Transportation at any time and to resolve all questions of claim eligibility pursuant to the terms and conditions described herein at its sole discretion. 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 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 ensure 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. 7-10 Recycled original equipment parts may also be used for repair. These parts are typically removed from vehicles that were total losses in prior crashes. 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. Repair Facility GM also recommends that you choose a collision repair facility that meets your needs before you ever need collision repairs. Your dealer/retailer 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. 7-11 If a Crash Occurs Here is what to do if you are involved in a crash. Try to relax and then check to make sure you 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 emergency services for help. Do not leave the scene of a crash 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:129) Give only the necessary and requested information to police and other parties involved in the crash. Do not discuss your personal condition, mental frame of mind, or anything unrelated to the crash. This will help guard against post-crash legal action. If you need roadside assistance, call GM Roadside Assistance. See Roadside Assistance Program on page 7-6 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:129) 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. (cid:129) 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 crash. 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. 7-12 (cid:129) (cid:129) (cid:129) (cid:129) (cid:129) 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. (cid:129) Choose a reputable collision repair facility for your vehicle. Whether you select a dealer/retailer 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:129) 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. 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. 7-13 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/retailer, 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. Washington D.C., 20590 You can also obtain other information about motor vehicle safety from http://www.safercar.gov. 7-14 Reporting Safety Defects to the Canadian Government If you live in Canada, and you believe that your vehicle has a safety defect, notify Transport Canada immediately, in addition to notifying General Motors of Canada Limited.

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. 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:129) How various systems in your vehicle were operating (cid:129) Whether or not the driver and passenger safety belts were buckled/fastened (cid:129) How far, if at all, the driver was pressing the accelerator and/or brake pedal (cid:129) 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. 7-16 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. 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 2-53 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. 7-17 ✍ NOTES 7-18 A Accessories and Modiﬁcations ............................ 5-3 Adding Equipment to Your Airbag-Equipped Vehicle ............................... 1-75 Additives, Fuel ................................................. 5-6 Add-On Electrical Equipment ........................... 5-110 Air Cleaner/Filter, Engine ................................. 5-18 Air Conditioning .............................................. 3-22 Airbag Off Light ..................................................... 3-35 Readiness Light .......................................... 3-34 Airbag System ................................................ 1-64 What Will You See After an Airbag Inﬂates? .... 1-70 When Should an Airbag Inﬂate? .................... 1-69 Where Are the Airbags? ............................... 1-66 Airbag Systems Adding Equipment to Your Airbag-Equipped Vehicle ............................ 1-75 Airbag Off Switch ........................................ 1-72 How Does an Airbag Restrain? ...................... 1-70 Servicing Your Airbag-Equipped Vehicle .......... 1-75 What Makes an Airbag Inﬂate? ...................... 1-70 Analog Clock .................................................. 3-21 Antenna, Fixed Mast ...................................... 3-118 Antenna, XM™ Satellite Radio Antenna System ..................................................... 3-118 Antilock Brake System (ABS) ............................. 4-4 Antilock Brake, System Warning Light ................ 3-39 Appearance Care Aluminum Wheels ...................................... 5-106 Care of Safety Belts ................................... 5-103 Chemical Paint Spotting .............................. 5-107 Cleaning Exterior Lamps/Lenses .................. 5-104 Fabric/Carpet ............................................ 5-101 Finish Care ............................................... 5-104 Finish Damage .......................................... 5-107 Instrument Panel, Vinyl, and Other Plastic Surfaces ..................................... 5-102 Interior Cleaning ........................................ 5-100 Leather .................................................... 5-102 Sheet Metal Damage .................................. 5-106 Speaker Covers ......................................... 5-103 Tires ........................................................ 5-106 Underbody Maintenance ............................. 5-107 Vehicle Care/Appearance Materials ............... 5-108 Washing Your Vehicle ................................. 5-103 Weatherstrips ............................................ 5-103 Windshield, Backglass, and Wiper Blades ...... 5-105 Wood Panels ............................................ 5-103 Appointments, Scheduling Service ....................... 7-8 Ashtray ......................................................... 3-21 Assist Steps ................................................... 4-32 Audio System ................................................. 3-72 Audio Steering Wheel Controls .................... 3-116 Fixed Mast Antenna ................................... 3-118 Navigation/Radio System, see Navigation Manual ............................ 3-104 Audio System (cont.)

Pictures and words work together 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. A box with the word CAUTION is used to tell about things that could hurt you or others if you were to ignore the warning. {CAUTION: These mean there is something that could hurt you or other people. We tell you what the hazard is and what to do to help avoid or reduce the hazard. Please read these cautions. If you do not, you or others could be hurt. A circle with a slash through it is a safety symbol which means “Do Not,” “Do Not do this” or “Do Not let this happen.” iii 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. Vehicle Damage Warnings You will also ﬁnd notices in this manual. 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. The notice tells 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 which use the same words, CAUTION or NOTICE. iv Section 1 Seats and Restraint Systems Front Seats ......................................................1-2 Power Seats ..................................................1-2 Power Lumbar ...............................................1-3 Heated Seats .................................................1-4 Memory Seat and Mirrors ................................1-4 Power Reclining Seatbacks ..............................1-5 Head Restraints .............................................1-7 Rear Seats .......................................................1-8 Heated Seats .................................................1-8 Split Folding Rear Seat ...................................1-8 Third Row Seat ............................................1-10 Safety Belts ...................................................1-16 Safety Belts: They Are for Everyone ................1-16 How to Wear Safety Belts Properly .................1-22 Lap-Shoulder Belt .........................................1-30 Safety Belt Use During Pregnancy ..................1-35 Safety Belt Extender .....................................1-35 Child Restraints .............................................1-36 Older Children ..............................................1-36 Infants and Young Children ............................1-39 Child Restraint Systems .................................1-43 Where to Put the Restraint .............................1-46 Lower Anchors and Tethers for Children (LATCH) ......................................1-47 Securing a Child Restraint in a Rear Seat Position ....................................1-57 Securing a Child Restraint in the Right Front Seat Position ............................1-60 Airbag System ...............................................1-64 Where Are the Airbags? ................................1-66 When Should an Airbag Inﬂate? .....................1-69 What Makes an Airbag Inﬂate? .......................1-70 How Does an Airbag Restrain? .......................1-70 What Will You See After an Airbag Inﬂates? .....1-70 Airbag Off Switch ..........................................1-72 Servicing Your Airbag-Equipped Vehicle ...........1-75 Adding Equipment to Your Airbag-Equipped Vehicle .............................1-75 Restraint System Check ..................................1-76 Checking the Restraint Systems ......................1-76 Replacing Restraint System Parts After a Crash ............................................1-77 1-1 On a vehicle with power seats, the controls used to operate them are located on the outboard side of the seats.

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. {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. CAUTION: (Continued) 1-6 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 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. To install the seat, do the following: 1. While holding the rear of the seat up, slide the front wheels into the slots on the ﬂoor. The front latches should lock into place. If the latches do not lock, try tilting the rear of the seat upward. 1-15 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. 2. Once the latches are engaged, pull up on the lever labeled 3 to allow the seat to drop into place. 3. Pull up on the lever labeled 1 to return the seatback to its upright position. 4. Push and pull on the seat to make sure it is locked into place. The seatback cannot be raised to the upright position unless the seat is secured to the ﬂoor. 1-16 Your vehicle has indicators as a reminder to buckle your safety belts. See Safety Belt Reminders on page 3-33. 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! {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. 1-17 Why Safety Belts Work When you ride in or on anything, you go as fast as it goes. Take the simplest vehicle. Suppose it is just a seat on wheels. Put someone on it. 1-18 Get it up to speed. Then stop the vehicle. The rider does not stop. The person keeps going until stopped by something. In a real vehicle, it could be the windshield... 1-19 or the instrument panel... 1-20 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. 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. 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. 1-21 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 1-36 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. 1-22 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. 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. 1-23 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. 1-24 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. 1-25 {CAUTION:
