High pressure car washes may cause water to enter the vehicle. 5-88 Cleaning Exterior Lamps/Lenses Use only lukewarm or cold water, a soft cloth and a car washing soap to clean exterior lamps and lenses. Follow instructions under Washing Your Vehicle on page 5-88. Finish Care Occasional waxing or mild polishing of your vehicle by hand may be necessary to remove residue from the paint ﬁnish. You can get GM-approved cleaning products from your dealer. See Vehicle Care/Appearance Materials on page 5-92. If your vehicle has a “basecoat/clearcoat” paint ﬁnish. The clearcoat gives more depth and gloss to the colored basecoat. Always use waxes and polishes that are non-abrasive and made for a basecoat/clearcoat paint ﬁnish. Notice: Machine compounding or aggressive polishing on a basecoat/clearcoat paint ﬁnish may damage it. Use only non-abrasive waxes and polishes that are made for a basecoat/clearcoat paint ﬁnish on your vehicle. Foreign materials such as calcium chloride and other salts, ice melting agents, road oil and tar, tree sap, bird droppings, chemicals from industrial chimneys, etc., can damage your vehicle’s ﬁnish if they remain on painted surfaces. Wash the vehicle as soon as possible. If necessary, use non-abrasive cleaners that are marked safe for painted surfaces to remove foreign matter. Exterior painted surfaces are subject to aging, weather and chemical fallout that can take their toll over a period of years. You can help to keep the paint ﬁnish looking new by keeping your vehicle garaged or covered whenever possible. Protecting Exterior Bright Metal Parts Bright metal parts should be cleaned regularly to keep their luster. Washing with water is all that is usually needed. However, you may use chrome polish on chrome or stainless steel trim, if necessary. Use special care with aluminum trim. To avoid damaging protective trim, never use auto or chrome polish, steam or caustic soap to clean aluminum. A coating of wax, rubbed to high polish, is recommended for all bright metal parts. 5-89 Windshield, Backglass, and Wiper Blades If the windshield is not clear after using the windshield washer, or if the wiper blade chatters when running, wax, sap or other material may be on the blade or windshield. Clean the outside of the windshield with a full-strength glass cleaning liquid. The windshield is clean if beads do not form when you rinse it with water. Grime from the windshield will stick to the wiper blades and affect their performance. Clean the blade by wiping vigorously with a cloth soaked in full-strength windshield washer solvent. Then rinse the blade with water. Check the wiper blades and clean them as necessary; replace blades that look worn. If you use strong soaps, chemicals, Aluminum Wheels Notice: abrasive polishes, cleaners, brushes, or cleaners that contain acid on aluminum or chrome-plated wheels, you could damage the surface of the wheel(s). The repairs would not be covered by your warranty. Use only GM-approved cleaners on aluminum or chrome-plated wheels. 5-90 Keep the wheels clean using a soft clean cloth with mild soap and water. Rinse with clean water. After rinsing thoroughly, dry with a soft clean towel. A wax may then be applied. Notice: Using chrome polish on aluminum wheels could damage the wheels. The repairs would not be covered by your warranty. Use chrome polish on chrome wheels only. The surface of these wheels is similar to the painted surface of the vehicle. Do not use strong soaps, chemicals, abrasive polishes, abrasive cleaners, cleaners with acid, or abrasive cleaning brushes on them because the surface could be damaged. Do not use chrome polish on aluminum wheels. Notice: automatic car wash that has silicone carbide tire cleaning brushes, you could damage the aluminum or chrome-plated wheels. The repairs would not be covered by your warranty. Never drive a vehicle equipped with aluminum or chrome-plated wheels through an automatic car wash that uses silicone carbide tire cleaning brushes. Do not take the vehicle through an automatic car wash that has silicone carbide tire cleaning brushes. These brushes can also damage the surface of these wheels. If you drive your vehicle through an Tires To clean the tires, use a stiff brush with tire cleaner. Notice: Using petroleum-based tire dressing products on your vehicle may damage the paint ﬁnish and/or tires. When applying a tire dressing, always wipe off any overspray from all painted surfaces on your vehicle. Sheet Metal Damage If the vehicle is damaged and requires sheet metal repair or replacement, make sure the body repair shop applies anti-corrosion material to parts repaired or replaced to restore corrosion protection. Original manufacturer replacement parts will provide the corrosion protection while maintaining the warranty. Finish Damage Any stone chips, fractures or deep scratches in the ﬁnish should be repaired right away. Bare metal will corrode quickly and may develop into major repair expense. Minor chips and scratches can be repaired with touch-up materials available from your GM dealer. Larger areas of ﬁnish damage can be corrected in your GM dealer’s body and paint shop. Underbody Maintenance Chemicals used for ice and snow removal and dust control can collect on the underbody. If these are not removed, corrosion and rust can develop on the underbody parts such as fuel lines, frame, ﬂoor pan, and exhaust system even though they have corrosion protection. At least every spring, ﬂush these materials from the underbody with plain water. Clean any areas where mud and debris can collect. Dirt packed in close areas of the frame should be loosened before being ﬂushed. Your GM dealer or an underbody car washing system can do this for you. Chemical Paint Spotting Some weather and atmospheric conditions can create a chemical fallout. Airborne pollutants can fall upon and attack painted surfaces on the vehicle. This damage can take two forms: blotchy, ring-shaped discolorations, and small, irregular dark spots etched into the paint surface. Although no defect in the paint job causes this, GM will repair, at no charge to the owner, the surfaces of new vehicles damaged by this fallout condition within 12 months or 12,000 miles (20 000 km) of purchase, whichever occurs ﬁrst. 5-91 Vehicle Care/Appearance Materials See your GM dealer for more information on purchasing the following products.

Odor Eliminator Spot Lifter Vehicle Identiﬁcation Vehicle Identiﬁcation Number (VIN) This is the legal identiﬁer for your vehicle. It appears on a plate in the front corner of the instrument panel, on the driver’s side. You can see it if you look through the windshield from outside your vehicle. The VIN also appears on the Vehicle Certiﬁcation and Service Parts labels and the certiﬁcates of title and registration. Engine Identiﬁcation The eighth character in your VIN is the engine code. This code will help you identify your engine, speciﬁcations and replacement parts. Service Parts Identiﬁcation Label You will ﬁnd this label on the inside of the glove box. It is very helpful if you ever need to order parts. On this label, you will ﬁnd the following: (cid:127) VIN (cid:127) Model designation (cid:127) Paint information (cid:127) Production options and special equipment Be sure that this label is not removed from the vehicle. 5-93 Electrical System Add-On Electrical Equipment Notice: Don’t add anything electrical to your vehicle unless you check with your dealer ﬁrst. Some electrical equipment can damage your vehicle and the damage wouldn’t be covered by your warranty. Some add-on electrical equipment can keep other components from working as they should. Your vehicle has an airbag system. Before attempting to add anything electrical to your vehicle, see Servicing Your Airbag-Equipped Vehicle on page 1-64. Headlamps The headlamp wiring is protected by four fuses. An electrical overload will cause a lamp to go on and off. If this happens, have your headlamp wiring checked right away. Windshield Wiper Fuses The windshield wiper motor is protected by a circuit breaker and a fuse. If the motor overheats due to heavy snow or ice, the wiper will stop until the motor cools. If the overload is caused by some electrical problem, be sure to get it ﬁxed. Power Windows and Other Power Options Circuit breakers protect the power windows and other power accessories. When the current load is too heavy, the circuit breaker opens and closes, protecting the circuit until the problem is ﬁxed or goes away. 5-94 Engine Compartment Fuse Block Fuses and Circuit Breakers The wiring circuits in your vehicle are protected from short circuits by a combination of fuses and circuit breakers. This greatly reduces the chance of ﬁres caused by electrical problems. Look at the silver-colored band inside the fuse. If the band is broken or melted, replace the fuse. Be sure you replace a bad fuse with a new one of the identical size and rating. If you ever have a problem on the road and don’t have a spare fuse, you can borrow one that has the same amperage. Just pick some feature of your vehicle that you can get along without — like the radio or cigarette lighter— and use its fuse, if it is the correct amperage. Replace it as soon as you can. The fuse block is located under the hood in the engine compartment on the driver’s side of the vehicle. See Engine Compartment Overview on page 5-12 for more information on location. Remove the primary cover by pressing the two locking tabs. Remove the secondary cover by snapping off while lifting. To reinstall the fuse panel cover, reverse the sequence. 5-95 L6 Engine 5-96 Fuses Usage Fuses Usage 10 11 12 13 14 15 16 17 18 19 20 Electrically-Controlled Air Suspension Passenger’s Side High-Beam

Have you purchased the GM Protection Plan? The Plan supplements your new vehicle warranties. See your Warranty and Owner Assistance booklet or your dealer for details. Maintenance Requirements Notice: Maintenance intervals, checks, inspections, replacement parts and recommended ﬂuids and lubricants as prescribed in this manual are necessary to keep your vehicle in good working condition. Any damage caused by failure to follow scheduled maintenance may not be covered by warranty. Your Vehicle and the Environment Proper vehicle maintenance not only helps to keep your vehicle in good working condition, but also helps the environment. All recommended maintenance is important. Improper vehicle maintenance can even affect the quality of the air we breathe. Improper ﬂuid levels or the wrong tire inﬂation can increase the level of emissions from your vehicle. To help protect our environment, and to keep your vehicle in good condition, be sure to maintain your vehicle properly. 6-2 Using Your Maintenance Schedule We at General Motors want to help you keep your vehicle in good working condition. But we do not know exactly how you will drive it. You may drive very short distances only a few times a week. Or you may drive long distances all the time in very hot, dusty weather. You may use your vehicle in making deliveries. Or you may drive it to work, to do errands or in many other ways. Because of all the different ways people use their vehicles, maintenance needs vary. You may need more frequent checks and replacements. So please read the following and note how you drive. If you have any questions on how to keep your vehicle in good condition, see your GM Goodwrench® dealer. This schedule is for vehicles that: carry passengers and cargo within recommended limits. You will ﬁnd these limits on the tire and loading information label. See Loading Your Vehicle on page 4-44. are driven on reasonable road surfaces within legal driving limits. are driven off-road in the recommended manner. See Off-Road Driving with Your Four-Wheel-Drive Vehicle on page 4-15. use the recommended fuel. See Gasoline Octane on page 5-5. The services in Scheduled Maintenance on page 6-5 should be performed when indicated. See Additional Required Services on page 6-7 and Maintenance Footnotes on page 6-9 for further information. 6-3 (cid:127) (cid:127) (cid:127) (cid:127) {CAUTION: Performing maintenance work on a vehicle can be dangerous. In trying to do some jobs, you can be seriously injured. Do your own maintenance work only if you have the required know-how and the proper tools and equipment for the job. If you have any doubt, see your GM Goodwrench® dealer to have a qualiﬁed technician do the work. Some maintenance services can be complex. So, unless you are technically qualiﬁed and have the necessary equipment, you should have your GM Goodwrench® dealer do these jobs. When you go to your GM Goodwrench® dealer for your service needs, you will know that GM-trained and supported service technicians will perform the work using genuine GM parts. If you want to purchase service information, see Service Publications Ordering Information on page 7-11. Owner Checks and Services on page 6-10 tells you what should be checked, when to check it and what you can easily do to help keep your vehicle in good condition. The proper replacement parts, ﬂuids and lubricants to use are listed in Recommended Fluids and Lubricants on page 6-14 and Normal Maintenance Replacement Parts on page 6-16. When your vehicle is serviced, make sure these are used. All parts should be replaced and all necessary repairs done before you or anyone else drives the vehicle. We recommend the use of genuine GM parts. 6-4 Scheduled Maintenance When the change engine oil light comes on, it means that service is required for your vehicle. Have your vehicle serviced as soon as possible within the next 600 miles (1 000 km). It is possible that, if you are driving under the best conditions, the engine oil life system may not indicate that vehicle service is necessary for over a year. However, your engine oil and ﬁlter must be changed at least once a year and at this time the system must be reset. Your GM Goodwrench® dealer has GM-trained service technicians who will perform this work using genuine GM parts and reset the system. If the engine oil life system is ever reset accidentally, you must service your vehicle within 3,000 miles (5 000 km) since your last service. Remember to reset the oil life system whenever the oil is changed. See Engine Oil Life System on page 5-18 for information on the Engine Oil Life System and resetting the system. When the change engine oil light appears, certain services, checks and inspections are required. Required services are described in the following for “Maintenance I” and “Maintenance II.” Generally, it is recommended that your ﬁrst service be Maintenance I, your second service be Maintenance II and that you alternate Maintenance I and Maintenance II thereafter. However, in some cases, Maintenance II may be required more often. Maintenance I — Use Maintenance I if the change engine oil light comes on within 10 months since the vehicle was purchased or Maintenance II was performed. Maintenance II — Use Maintenance II if the previous service performed was Maintenance I. Always use Maintenance II whenever the light comes on 10 months or more since the last service or if the light has not come on at all for one year. 6-5 Scheduled Maintenance Service Maintenance I Maintenance II Change engine oil and ﬁlter.

We, however, urge that all recommended maintenance services be performed at the indicated intervals and the maintenance be recorded. (a) Visually inspect brake lines and hoses for proper hook-up, binding, leaks, cracks, chaﬁng, etc. Inspect disc brake pads for wear and rotors for surface condition. Inspect other brake parts, including calipers, parking brake, etc. (b) Visually inspect front and rear suspension and steering system for damaged, loose or missing parts or signs of wear. Inspect power steering lines and hoses for proper hook-up, binding, leaks, cracks, chaﬁng, etc. (c) Visually inspect hoses and have them replaced if they are cracked, swollen or deteriorated. Inspect all pipes, ﬁttings and clamps; replace with genuine GM parts as needed. To help ensure proper operation, a pressure test of the cooling system and pressure cap and cleaning the outside of the radiator and air conditioning condenser is recommended at least once a year. (d) Visually inspect wiper blades for wear or cracking. Replace blade inserts that appear worn or damaged or that streak or miss areas of the windshield. (e) Make sure the safety belt reminder light and all your belts, buckles, latch plates, retractors and anchorages are working properly. Look for any other loose or damaged safety belt system parts. If you see anything that might keep a safety belt system from doing its job, have it repaired. Have any torn or frayed safety belts replaced. Also look for any opened or broken airbag coverings, and have them repaired or replaced. (The airbag system does not need regular maintenance.) (f) Lubricate all key lock cylinders, hood latch assembly, secondary latch, pivots, spring anchor, release pawl, rear compartment hinges, outer liftgate handle pivot points, rear door detent link, roller mechanism, liftgate handle pivot points, latch bolt, fuel door hinge, cargo door hinge, locks and folding seat hardware. More frequent lubrication may be required when exposed to a corrosive environment. Applying silicone grease on weatherstrips with a clean cloth will make them last longer, seal better and not stick or squeak. (g) Check vent hose at transfer case for kinks and proper installation. 6-9 (h) Change automatic transmission ﬂuid and ﬁlter if the vehicle is mainly driven under one or more of these conditions: − In heavy city traffic where the outside temperature regularly reaches 90°F (32°C) or higher. − In hilly or mountainous terrain. − When doing frequent trailer towing. − Uses such as found in taxi, police or delivery service. (i) Drain, ﬂush and reﬁll cooling system. This service can be complex; you should have your dealer perform this service. See Engine Coolant on page 5-24 for what to use. Inspect hoses. Clean radiator, condenser, pressure cap and ﬁller neck. Pressure test the cooling system and pressure cap. (j) A ﬂuid loss in any vehicle system could indicate a problem. Have the system inspected and repaired and the ﬂuid level checked. Add ﬂuid if needed. (k) If you drive regularly under dusty conditions, inspect the ﬁlter at each engine oil change. Owner Checks and Services These owner checks and services should be performed at the intervals speciﬁed to help ensure the safety, dependability and emission control performance of your vehicle. Your GM Goodwrench® dealer can assist you with these checks and services. Be sure any necessary repairs are completed at once. Whenever any ﬂuids or lubricants are added to your vehicle, make sure they are the proper ones, as shown in Recommended Fluids and Lubricants on page 6-14. At Each Fuel Fill It is important to perform these underhood checks at each fuel ﬁll. Engine Oil Level Check Check the engine oil level and add the proper oil if necessary. See Engine Oil on page 5-15 for further details. Notice: and keep it at the proper level. Failure to keep your engine oil at the proper level can cause damage to your engine not covered by your warranty. It is important to check your oil regularly 6-10 Engine Coolant Level Check Check the engine coolant level and add DEX-COOL® coolant mixture if necessary. See Engine Coolant on page 5-24 for further details. Windshield Washer Fluid Level Check Check the windshield washer ﬂuid level in the windshield washer tank and add the proper ﬂuid if necessary. At Least Once a Month Tire Inﬂation Check Visually inspect your tires and make sure tires are inﬂated to the correct pressures. Do not forget to check your spare tire. See Tires on page 5-53 for further details. Check to make sure the spare tire is stored securely. Push, pull and then try to turn the spare tire. If it moves, tighten it. See Changing a Flat Tire on page 5-70. At Least Once a Year Starter Switch Check {CAUTION: When you are doing this inspection, the vehicle could move suddenly. If the vehicle moves, you or others could be injured. 1. Before you start, be sure you have enough room around the vehicle. 2. Firmly apply both the parking brake and the regular brake. See Parking Brake on page 2-31 if necessary. Do not use the accelerator pedal, and be ready to turn off the engine immediately if it starts. 3. Try to start the engine in each gear. The starter should work only in PARK (P) or NEUTRAL (N). If the starter works in any other position, contact your GM Goodwrench® dealer for service. 6-11 Automatic Transmission Shift Lock Control System Check {CAUTION: When you are doing this inspection, the vehicle could move suddenly. If the vehicle moves, you or others could be injured. Ignition Transmission Lock Check While parked, and with the parking brake set, try to turn the ignition to LOCK in each shift lever position. The ignition should turn to LOCK only when the shift lever is in PARK (P). The key should come out only in LOCK. Contact your GM Goodwrench® dealer if service is required. 1. Before you start, be sure you have enough room around the vehicle. It should be parked on a level surface. 2. Firmly apply the parking brake. See Parking Brake on page 2-31 if necessary. Be ready to apply the regular brake immediately if the vehicle begins to move. 3. With the engine off, turn the ignition to RUN, but do not start the engine. Without applying the regular brake, try to move the shift lever out of PARK (P) with normal effort. If the shift lever moves out of PARK (P), contact your GM Goodwrench® dealer for service. 6-12 (cid:127) (cid:127) Parking Brake and Automatic Transmission Park (P) Mechanism Check Park on a fairly steep hill, with the vehicle facing downhill.

Normally, any concerns with the sales transaction or the operation of your vehicle will be resolved by your dealer’s sales or service departments. Sometimes, however, despite the best intentions of all concerned, misunderstandings can occur. If your concern has not been resolved to your satisfaction, the following steps should be taken: STEP ONE: Discuss your concern with a member of dealership management. Normally, concerns can be quickly resolved at that level. If the matter has already been reviewed with the sales, service or parts manager, contact the owner of the dealership or the general manager. STEP TWO: If after contacting a member of dealership management, it appears your concern cannot be resolved by the dealership without further help, contact the Chevrolet Customer Assistance Center by calling 1-800-222-1020. In Canada, contact GM of Canada Customer Communication Centre by calling 1-800-263-3777 (English) or 1-800-263-7854 (French). 7-2 We encourage you to call the toll-free number in order to give your inquiry prompt attention. Please have the following information available to give the Customer Assistance Representative: (cid:127) Vehicle Identiﬁcation Number (VIN). This is available from the vehicle registration or title, or the plate at the top left of the instrument panel and visible through the windshield. (cid:127) Dealership name and location. (cid:127) Vehicle delivery date and present mileage (kilometers). When contacting Chevrolet, please remember that your concern will likely be resolved at a dealer’s facility. That is why we suggest you follow Step One ﬁrst if you have a concern. STEP THREE: Both General Motors and your dealer are committed to making sure you are completely satisﬁed with your new vehicle. However, if you continue to remain unsatisﬁed after following the procedure outlined in Steps One and Two, you should ﬁle with the BBB Auto Line Program to enforce any additional rights you may have. Canadian owners refer to your Warranty and Owner Assistance Information booklet for information on the Canadian Motor Vehicle Arbitration Plan (CAMVAP). The BBB Auto Line Program is an out of court program administered by the Council of Better Business Bureaus to settle automotive disputes regarding vehicle repairs or the interpretation of the New Vehicle Limited Warranty. Although you may be required to resort to this informal dispute resolution program prior to ﬁling a court action, use of the program is free of charge and your case will generally be heard within 40 days. If you do not agree with the decision given in your case, you may reject it and proceed with any other venue for relief available to you. You may contact the BBB Auto Line Program using the toll-free telephone number or write them at the following address: BBB Auto Line Program Council of Better Business Bureaus, Inc. 4200 Wilson Boulevard Suite 800 Arlington, VA 22203-1838 Telephone: 1-800-955-5100 This program is available in all 50 states and the District of Columbia. Eligibility is limited by vehicle age, mileage, and other factors. General Motors reserves the right to change eligibility limitations and/or discontinue its participation in this program.

To enhance your ownership experience, we and our participating dealers are proud to offer Courtesy Transportation, a customer support program for new vehicles. The Courtesy Transportation program is offered to retail purchase/lease customers in conjunction with the Bumper-to-Bumper coverage provided by the New Vehicle Limited Warranty. Several transportation options are available when warranty repairs are required. This will reduce your inconvenience during warranty repairs. Scheduling Service Appointments When your vehicle requires warranty service, you should contact your dealer and request an appointment. By scheduling a service appointment and advising your service consultant of your transportation needs, your dealer can help minimize your inconvenience. 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, let them know this, and ask for instructions. If the dealer 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 same day repair. Transportation Options Warranty service can generally be completed while you wait. However, if you are unable to wait, Chevrolet helps 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 you with shuttle service to get you to your destination with minimal interruption of your daily schedule. This includes a one way or round trip shuttle service to a destination up to 10 miles (16 km) from the dealership. 7-7 Public Transportation or Fuel Reimbursement If your vehicle requires overnight warranty repairs, reimbursement of up to a ﬁve-day maximum may be available for the use of public transportation such as a taxi or bus. In addition, should you arrange transportation through a friend or relative, reimbursement for reasonable fuel expenses of up to a ﬁve-day maximum may be available. Claim amounts should reﬂect actual costs and be supported by original receipts. 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. Reimbursement will be limited to a maximum of $30.00 a day and must be supported by 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. Generally it is not possible to provide a like-vehicle as a courtesy rental. 7-8 Additional Program Information Courtesy Transportation is available during the Bumper-to-Bumper warranty coverage period, but it is not 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. Courtesy Transportation is available only at participating GM dealers and all program options, such as shuttle service, may not be available at every dealer. Please contact your GM dealer for speciﬁc information about availability. All Courtesy Transportation arrangements will be administered by appropriate dealer personnel. Canadian Vehicles: For warranty repairs during the Complete Vehicle Coverage period of the General Motors of Canada New Vehicle Limited Warranty, alternative transportation may be available under the Courtesy Transportation Program. Please consult your dealer for details. 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. 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 so equipped, 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, 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
