When cleaning the vehicle’s interior, only use cleaners speciﬁcally designed for the surfaces being cleaned. Permanent damage may result from using cleaners on surfaces for which they were not intended. Use glass cleaner only on glass. Remove any accidental over-spray from other surfaces immediately. To prevent over-spray, apply cleaner directly to the cleaning cloth. Notice: Using abrasive cleaners when cleaning glass surfaces on the vehicle, could scratch the glass and/or cause damage to the rear window defogger. When cleaning the glass on the vehicle, use only a soft cloth and glass cleaner. Many cleaners contain solvents that may become concentrated in the vehicle’s breathing space. Before using cleaners, read and adhere to all safety instructions on the label. While cleaning the vehicle’s interior, maintain adequate ventilation by opening the vehicle’s doors and windows. Dust may be removed from small buttons and knobs using a small brush with soft bristles. Products that remove odors from the vehicle’s upholstery and clean the vehicle’s glass can be obtained from your dealer/retailer. Do not clean the vehicle using: (cid:129) A knife or any other sharp object to remove a soil from any interior surface. (cid:129) A stiff brush. It can cause damage to the vehicle’s interior surfaces. (cid:129) Heavy pressure or aggressive rubbing with a cleaning cloth. Use of heavy pressure can damage the interior and does not improve the effectiveness of soil removal. Laundry detergents or dishwashing soaps with degreasers can leave residue that streaks and attracts dirt. For liquid cleaners, about 20 drops per gallon (3.78 L) of water is a good guide. Use only mild, neutral-pH soaps. Too much cleaner that saturates the upholstery. (cid:129) Organic solvents such as naptha, alcohol, etc. that can damage the vehicle’s interior. Fabric/Carpet Use a vacuum cleaner with a soft brush attachment frequently to remove dust and loose dirt. A canister vacuum with a beater bar in the nozzle may only be used on ﬂoor carpet and carpeted ﬂoor mats. For any soil, always try to remove it ﬁrst with plain water or club soda. Service and Appearance Care 5-81 Before cleaning, gently remove as much of the soil as possible using one of the following techniques: For liquids: gently blot the remaining soil with a paper towel. Allow the soil to absorb into the paper towel until no more can be removed. For solid dry soils: remove as much as possible and then vacuum. To clean: 1. Saturate a lint-free, clean white cloth with water or club soda. 2. Wring the cloth to remove excess moisture. 3. Start on the outside edge of the soil and gently rub toward the center. Continue cleaning, using a clean area of the cloth each time it becomes soiled. 4. Continue to gently rub the soiled area until the cleaning cloth remains clean. 5. If the soil is not completely removed, use a mild soap solution and repeat the cleaning process that was used with plain water. If any of the soil remains, a commercial fabric cleaner or spot lifter may be necessary. When a commercial upholstery cleaner or spot lifter is to be used, test a small hidden area for colorfastness ﬁrst. If the locally cleaned area gives any impression that a ring formation may result, clean the entire surface. After the cleaning process has been completed, a paper towel can be used to blot excess moisture from the fabric or carpet. (cid:129) (cid:129) (cid:129) (cid:129) 5-82 Service and Appearance Care Leather A soft cloth dampened with water can be used to remove dust. If a more thorough cleaning is necessary, a soft cloth dampened with a mild soap solution can be used. Allow the leather to dry naturally. Do not use heat to dry. Never use steam to clean leather. Never use spot lifters or spot removers on leather. Many commercial leather cleaners and coatings that are sold to preserve and protect leather may permanently change the appearance and feel of the leather and are not recommended. Do not use silicone or wax-based products, or those containing organic solvents to clean the vehicle’s interior because they can alter the appearance by increasing the gloss in a non-uniform manner. Never use shoe polish on leather. Instrument Panel, Vinyl, and Other Plastic Surfaces A soft cloth dampened with water may be used to remove dust. If a more thorough cleaning is necessary, a clean soft cloth dampened with a mild soap solution can be used to gently remove dust and dirt. Never use spot lifters or removers on plastic surfaces. Many commercial cleaners and coatings that are sold to preserve and protect soft plastic surfaces may permanently change the appearance and feel of the interior and are not recommended. Do not use silicone or wax-based products, or those containing organic solvents to clean the vehicle’s interior because they can alter the appearance by increasing the gloss in a non-uniform manner. Some commercial products may increase gloss on the instrument panel. The increase in gloss may cause annoying reﬂections in the windshield and even make it difficult to see through the windshield under certain conditions. Care of Safety Belts Keep belts clean and dry. { CAUTION Do not bleach or dye safety belts. It may severely weaken them. In a crash, they might not be able to provide adequate protection. Clean safety belts only with mild soap and lukewarm water. Service and Appearance Care 5-83 Weatherstrips Silicone grease on weatherstrips will make them last longer, seal better, and not stick or squeak. Apply silicone grease with a clean cloth. During very cold, damp weather frequent application may be required. See Recommended Fluids and Lubricants on page 6-12. Washing Your Vehicle The best way to preserve the vehicle’s ﬁnish is to keep it clean by washing it often. Notice: Certain cleaners contain chemicals that can damage the emblems or nameplates on the vehicle. Check the cleaning product label. If it states that it should not be used on plastic parts, do not use it on the vehicle or damage may occur and it would not be covered by the warranty. Do not wash the vehicle in direct sunlight. Use a car washing soap. Do not use cleaning agents that are petroleum based or that contain acid or abrasives, as they can damage the paint, metal or plastic on the vehicle. Approved cleaning products can be obtained from your dealer/ retailer. Follow all manufacturers’ directions regarding correct product usage, necessary safety precautions and appropriate disposal of any vehicle care product. Rinse the vehicle well, before washing and after to remove all cleaning agents completely. If they are allowed to dry on the surface, they could stain. Dry the ﬁnish with a soft, clean chamois or an all-cotton towel to avoid surface scratches and water spotting. High pressure car washes may cause water to enter the vehicle. Avoid using high pressure washes closer than 12 inches (30 cm) to the surface of the vehicle. Use of power washers exceeding 1,200 psi (8 274 kPa) can result in damage or removal of paint and decals. 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 5-83. 5-84 Service and Appearance Care Finish Care Occasional waxing or mild polishing of the vehicle by hand may be necessary to remove residue from the paint ﬁnish. Approved cleaning products can be obtained from your dealer/retailer. If the 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 the 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 the 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. To help keep the paint ﬁnish looking new, keep the 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, chrome polish may be used 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. Windshield, Backglass, and Wiper Blades Clean the outside of the windshield and backglass with glass cleaner. Clean the rubber blades using a lint free cloth or paper towel soaked with windshield washer ﬂuid or a mild detergent. Wash the windshield thoroughly when you clean the blades. Bugs, road grime, sap and a buildup of vehicle wash/wax treatments may cause wiper streaking. Replace the wiper blades if they are worn or damaged. Wipers can be damaged by: (cid:129) Extreme dusty conditions (cid:129) Sand and salt (cid:129) Heat and sun (cid:129) Snow and ice, without proper removal Service and Appearance Care 5-85 Aluminum or Chrome-Plated Wheels and Trim The vehicle may have either aluminum or chrome-plated wheels. 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: Chrome wheels and other chrome trim may be damaged if the vehicle is not washed after driving on roads that have been sprayed with magnesium, calcium or sodium chloride. These chlorides are used on roads for conditions such as ice and dust. Always wash the vehicle’s chrome with soap and water after exposure. Notice: Using strong soaps, chemicals, abrasive polishes, cleaners, brushes, or cleaners that contain acid on aluminum or chrome-plated wheels, could damage the surface of the wheel(s). The repairs would not be covered by the vehicle warranty. Use only approved cleaners on aluminum or chrome-plated wheels. 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 they could damage the surface. Do not use chrome polish on aluminum wheels. Notice: Using chrome polish on aluminum wheels could damage the wheels. The repairs would not be covered by the vehicle warranty. Use chrome polish on chrome wheels only. Use chrome polish only on chrome-plated wheels, but avoid any painted surface of the wheel, and buff off immediately after application. Notice: Driving the vehicle through an automatic car wash that has silicone carbide tire cleaning brushes, could damage the aluminum or chrome-plated wheels. The repairs would not be covered by the vehicle warranty. Never drive a vehicle that has aluminum or chrome-plated wheels through an automatic car wash that uses silicone carbide tire cleaning brushes. Tires To clean the tires, use a stiff brush with tire cleaner. Notice: Using petroleum-based tire dressing products on the vehicle may damage the paint ﬁnish and/or tires. When applying a tire dressing, always wipe off any overspray from all painted surfaces on the vehicle. 5-86 Service and Appearance Care 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 dealer/retailer or an underbody car washing system can do this. 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, we 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. 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 vehicle 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 dealer/retailer. Larger areas of ﬁnish damage can be corrected in your dealer’s/retailer’s body and paint shop. Service and Appearance Care 5-87 Service Parts Identiﬁcation Label This label is on the inside of the glove box. It is very helpful if parts need to be ordered. The label has the following information: (cid:129) Vehicle Identiﬁcation Number (VIN) (cid:129) Model designation (cid:129) Paint information (cid:129) Production options and special equipment Do not remove this label from the vehicle. Electrical System High Voltage Devices and Wiring { CAUTION Exposure to high voltage can cause shock, burns, and even death. The high voltage systems in your vehicle can only be serviced by technicians with special training. High voltage devices are identiﬁed by labels. Do not remove, open, take apart, or modify these devices. High voltage cable or wiring has orange covering. Do not probe, tamper with, cut, or modify high voltage cable or wiring. Vehicle Identiﬁcation Vehicle Identiﬁcation Number (VIN) This is the legal identiﬁer for the vehicle. It appears on a plate in the front corner of the instrument panel, on the driver side. It can be seen through the windshield from outside the 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 the VIN is the engine code. This code helps identify the vehicle’s engine, speciﬁcations, and replacement parts. See “Engine Speciﬁcations” under Capacities and Speciﬁcations on page 5-94 for the vehicle’s engine code. 5-88 Service and Appearance Care Add-On Electrical Equipment Notice: Do not add anything electrical to the vehicle unless you check with your dealer/retailer ﬁrst. Some electrical equipment can damage the vehicle and the damage would not be covered by the vehicle’s warranty. Some add-on electrical equipment can keep other components from working as they should. Add-on equipment can drain the vehicle’s battery, even if the vehicle is not operating. The vehicle has an airbag system. Before attempting to add anything electrical to the vehicle, see Servicing Your Airbag-Equipped Vehicle on page 1-61. 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, have it ﬁxed. Power Windows and Other Power Options Circuit breakers in the fuse block 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. Fuses and Circuit Breakers The wiring circuits in your vehicle are protected from short circuits by a combination of fuses, circuit breakers and fusible thermal links. 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. Fuses of the same amperage can be temporarily borrowed from another fuse location, if a fuse goes out. Replace the fuse as soon as you can. Instrument Panel Fuse Block The instrument panel fuse block is located under the instrument panel on the passenger side of the vehicle. Pull down on the cover to access the fuse block.

Maintenance Schedule 6-1 Maintenance Requirements Notice: Maintenance intervals, checks, inspections, replacement parts, and recommended ﬂuids and lubricants as prescribed in this manual are necessary to keep this vehicle in good working condition. Any damage caused by failure to follow scheduled maintenance might not be covered by the vehicle warranty. Your Vehicle and the Environment Proper vehicle maintenance not only helps to keep the 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 the vehicle. 6-2 Maintenance Schedule To help protect the environment, and to keep the vehicle in good condition, be sure to maintain the vehicle properly. Using the Maintenance Schedule We want to help keep this vehicle in good working condition. But we do not know exactly how you will drive it. You might drive very short distances only a few times a week. Or you might drive long distances all the time in very hot, dusty weather. You might use the vehicle in making deliveries. Or you might 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 might 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 the vehicle in good condition, see your dealer/retailer. This schedule is for vehicles that: carry passengers and cargo within recommended limits on the Tire and Loading Information label. See Loading the Vehicle on page 4-16. are driven on reasonable road surfaces within legal driving limits. use the recommended fuel. See Gasoline Octane on page 5-5. The services in Scheduled Maintenance on page 6-3 should be performed when indicated. See Additional Required Services on page 6-6 and Maintenance Footnotes on page 6-7 for further information. { 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 dealer/retailer to have a qualiﬁed technician do the work. See Doing Your Own Service Work on page 5-4. Some maintenance services can be complex. So, unless you are technically qualiﬁed and have the necessary equipment, have your dealer/retailer do these jobs. When you go to your dealer/retailer for service, trained and supported service technicians will perform the work using genuine parts. (cid:129) (cid:129) (cid:129) To purchase service information, see Service Publications Ordering Information on page 7-15. Owner Checks and Services on page 6-9 tells what should be checked, when to check it, and what can easily be done to help keep the vehicle in good condition. The proper replacement parts, ﬂuids, and lubricants to use are listed in Recommended Fluids and Lubricants on page 6-12 and Maintenance Replacement Parts on page 6-14. When the 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 parts from your dealer/retailer. Scheduled Maintenance When the CHANGE ENGINE OIL SOON message displays, service is required for the vehicle. Have the vehicle serviced as soon as possible within the next 600 miles (1 000 km). It is possible that, if driving under the best conditions, the engine oil life system might not indicate that vehicle service is necessary for over a year. However, the engine oil and ﬁlter must be changed at least once a year and at this time the system must be reset. Your dealer/retailer has trained service technicians who will perform this work using genuine parts and reset the system. If the engine oil life system is ever reset accidentally, service the vehicle within 3,000 miles (5 000 km) since the last service. Remember to reset Maintenance Schedule 6-3 the oil life system whenever the oil is changed. See Engine Oil Life System on page 5-15 for information on the Engine Oil Life System and resetting the system. When the CHANGE ENGINE OIL SOON message 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 the ﬁrst service be Maintenance I, the second service be Maintenance II, and then alternate Maintenance I and Maintenance II thereafter. However, in some cases, Maintenance II may be required more often. 6-4 Maintenance Schedule Maintenance I — Use Maintenance I if the CHANGE ENGINE OIL SOON message displays 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.

Owner Checks and Services These owner checks and services should be performed at the intervals speciﬁed to help ensure vehicle safety, dependability, and emission control performance. Your dealer/ retailer can assist with these checks and services. Be sure any necessary repairs are completed at once. Whenever any ﬂuids or lubricants are added to the vehicle, make sure they are the proper ones, as shown in Recommended Fluids and Lubricants on page 6-12. At Each Fuel Fill It is important to perform these underhood checks at each fuel ﬁll. Maintenance Schedule 6-9 At Least Once a Month Tire Inﬂation Check Inspect the vehicle’s tires and make sure they are inﬂated to the correct pressures. Do not forget to check the spare tire, if the vehicle has one. See Inﬂation - Tire Pressure on page 5-43. If the vehicle has a spare tire, check to make sure it is stored securely. See Changing a Flat Tire on page 5-66. Tire Wear Inspection Tire rotation may be required for high mileage highway drivers prior to the Engine Oil Life System service notiﬁcation. Check the tires for wear and, if necessary, rotate the tires. See Tire Inspection and Rotation on page 5-50.

Normally, any concerns with the sales transaction or the operation of the vehicle will be resolved by the 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. 7-2 Customer Assistance Information STEP TWO: If after contacting a member of dealership management, it appears your concern cannot be resolved by the dealership without further help, in the U.S., call the GMC Consumer Relations Manager at 1-800-GMC-8782 (1-800-462-8782, Customer Assistance prompt). In Canada, call General Motors of Canada Customer Communication at 1-800-263-3777 (English) or 1-800-263-7854 (French). We encourage you to call the toll-free number in order to give your inquiry prompt attention. Have the following information available to give the Customer Assistance Representative: (cid:129) 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:129) Dealership name and location. (cid:129) Vehicle delivery date and present mileage. When contacting GMC, remember that your concern will likely be resolved at a dealer’s facility. That is why we suggest following Step One ﬁrst. STEP THREE — U.S. Owners: 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 can ﬁle with the Better Business Bureau (BBB) Auto Line Program to enforce your rights. 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 ﬁlling out 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 dr.bbb.org/goauto This program is available in all 50 states and the District of Columbia.

General Motors of Canada Limited has committed to binding arbitration of owner disputes involving factory-related vehicle service claims.
