Traction: The friction between the tire and the road surface. The amount of grip provided. Tread: The portion of a tire that comes into contact with the road. Treadwear Indicators: Narrow bands, sometimes called “wear bars,” that show across the tread of a tire when only 1/16 inch (1.6 mm) of tread remains. See When It Is Time for New Tires on page 5-66. UTQGS (Uniform Tire Quality Grading Standards): A tire information system that provides consumers with ratings for a tire’s traction, temperature, and treadwear. Ratings are determined by tire manufacturers using government testing procedures. The ratings are molded into the sidewall of the tire. See Uniform Tire Quality Grading on page 5-68. Vehicle Capacity Weight: The number of designated seating positions multiplied by 150 lbs (68 kg) plus the rated cargo load. See Loading Your Vehicle on page 4-28. Vehicle Maximum Load on the Tire: Load on an individual tire due to curb weight, accessory weight, occupant weight, and cargo weight. Vehicle Placard: A label permanently attached to a vehicle showing the vehicle’s capacity weight and the original equipment tire size and recommended inﬂation pressure. See “Tire and Loading Information Label” under Loading Your Vehicle on page 4-28. 5-63 Inﬂation - Tire Pressure Tires need the correct amount of air pressure to operate effectively. Notice: Do not let anyone tell you that under-inﬂation or over-inﬂation is all right. It is not. If your tires do not have enough air (under-inﬂation), you can get the following: Too much ﬂexing Too much heat Tire overloading (cid:127) Premature or irregular wear (cid:127) Poor handling (cid:127) Reduced fuel economy If your tires have too much air (over-inﬂation), you can get the following: (cid:127) Unusual wear (cid:127) Poor handling (cid:127) Rough ride (cid:127) Needless damage from road hazards A Tire and Loading Information label is attached to the vehicle’s center pillar (B-pillar), below the driver’s door latch. This label shows your vehicle’s original equipment tires and the correct inﬂation pressures for your tires when they are cold. The recommended cold tire inﬂation pressure, shown on the label, is the minimum amount of air pressure needed to support your vehicle’s maximum load carrying capacity. For additional information regarding how much weight your vehicle can carry, and an example of the tire and loading information label, see Loading Your Vehicle on page 4-28. How you load your vehicle affects vehicle handling and ride comfort, never load your vehicle with more weight than it was designed to carry. When to Check Check your tires once a month or more. Do not forget to check the compact spare tire, it should be at 60 psi (420 kPa). For additional information regarding the compact spare tire, see Compact Spare Tire on page 5-84. How to Check Use a good quality pocket-type gage to check tire pressure. You cannot tell if your tires are properly inﬂated simply by looking at them. Radial tires may look properly inﬂated even when they are under-inﬂated. 5-64 (cid:127) (cid:127) (cid:127) Check the tire’s inﬂation pressure when the tires are cold. Cold means your vehicle has been sitting for at least three hours or driven no more than 1 mile (1.6 km). Remove the valve cap from the tire valve stem. Press the tire gage ﬁrmly onto the valve to get a pressure measurement. If the cold tire inﬂation pressure matches the recommended pressure on the Tire and Loading Information label, no further adjustment is necessary. If the inﬂation pressure is low, add air until you reach the recommended amount. If you overﬁll the tire, release air by pushing on the metal stem in the center of the tire valve. Re-check the tire pressure with the tire gage. Be sure to put the valve caps back on the valve stems. They help prevent leaks by keeping out dirt and moisture. Tire Inspection and Rotation Tires should be rotated every 5,000 to 8,000 miles (8 000 to 13 000 km). Any time you notice unusual wear, rotate your tires as soon as possible and check wheel alignment. Also check for damaged tires or wheels. See When It Is Time for New Tires on page 5-66 and Wheel Replacement on page 5-70 for more information. Make sure the spare tire is stored securely. Push, pull, and then try to rotate or turn the tire. If it moves, use the ratchet/wheel wrench to tighten the cable. See Changing a Flat Tire on page 5-72. The purpose of regular rotation is to achieve more uniform wear for all tires on the vehicle. The ﬁrst rotation is the most important. See Part A: Scheduled Maintenance Services on page 6-4. When rotating your tires, always use the correct rotation patterns shown here. Do not include the compact spare tire in your tire rotation. 5-65 After the tires have been rotated, adjust the front and rear inﬂation pressures as shown on the Tire and Loading Information label. See Inﬂation - Tire Pressure on page 5-64 and Loading Your Vehicle on page 4-28. Make certain that all wheel nuts are properly tightened. See “Wheel Nut Torque” under Capacities and Speciﬁcations on page 5-101. {CAUTION: Rust or dirt on a wheel, or on the parts to which it is fastened, can make wheel nuts become loose after a time. The wheel could come off and cause an accident. When you change a wheel, remove any rust or dirt from places where the wheel attaches to the vehicle. In an emergency, you can use a cloth or a paper towel to do this; but be sure to use a scraper or wire brush later, if you need to, to get all the rust or dirt off. See Changing a Flat Tire on page 5-72. 5-66 When It Is Time for New Tires One way to tell when it’s time for new tires is to check the treadwear indicators, which will appear when your tires have only 1/16 inch (1.6 mm) or less of tread remaining. Some commercial truck tires may not have treadwear indicators. You need a new tire if any of the following statements are true: (cid:127) You can see the indicators at three or more places around the tire. (cid:127) You can see cord or fabric showing through the tire’s rubber. The tread or sidewall is cracked, cut or snagged deep enough to show cord or fabric. The tire has a bump, bulge or split. The tire has a puncture, cut or other damage that can’t be repaired well because of the size or location of the damage. (cid:127) (cid:127) (cid:127) Buying New Tires To ﬁnd out what kind and size of tires you need, look at the Certiﬁcation/Tire label or the Tire and Loading Information label. See Loading Your Vehicle on page 4-28, for examples of the labels and where they can be found on your vehicle. The tires installed on your vehicle when it was new had a Tire Performance Criteria Speciﬁcation (TPC Spec) number on each tire’s sidewall. When you get new tires, GM recommends that you get tires with that same TPC Spec number. That way your vehicle will continue to have tires that are designed to give proper endurance, handling, speed rating, traction, ride and other things during normal service on your vehicle. If your tires have an all-season tread design, the TPC number will be followed by an “MS” (for mud and snow). If you ever replace your tires with those not having a TPC Spec number, make sure they are the same size, load range, speed rating and construction type (bias, bias-belted or radial) as your original tires. {CAUTION: Mixing tires could cause you to lose control while driving. If you mix tires of different sizes or types (radial and bias-belted tires), the vehicle may not handle properly, and you could have a crash. Using tires of different sizes may also cause damage to your vehicle. Be sure to use the same size and type tires on all wheels. It’s all right to drive with your compact spare temporarily, it was developed for use on your vehicle. See Compact Spare Tire on page 5-84. {CAUTION: If you use bias-ply tires on your vehicle, the wheel rim ﬂanges could develop cracks after many miles of driving. A tire and/or wheel could fail suddenly, causing a crash. Use only radial-ply tires with the wheels on your vehicle. 5-67 Uniform Tire Quality Grading Quality grades can be found where applicable on the tire sidewall between tread shoulder and maximum section width. For example: Treadwear 200 Traction AA Temperature A The following information relates to the system developed by the United States National Highway Traffic Safety Administration, which grades tires by treadwear, traction and temperature performance. (This applies only to vehicles sold in the United States.) The grades are molded on the sidewalls of most passenger car tires. The Uniform Tire Quality Grading system does not apply to deep tread, winter-type snow tires, space-saver or temporary use spare tires, tires with nominal rim diameters of 10 to 12 inches (25 to 30 cm), or to some limited-production tires. While the tires available on General Motors passenger cars and light trucks may vary with respect to these grades, they must also conform to federal safety requirements and additional General Motors Tire Performance Criteria (TPC) standards. Treadwear The treadwear grade is a comparative rating based on the wear rate of the tire when tested under controlled conditions on a speciﬁed government test course. For example, a tire graded 150 would wear one and a half (1.5) times as well on the government course as a tire graded 100. The relative performance of tires depends upon the actual conditions of their use, however, and may depart signiﬁcantly from the norm due to variations in driving habits, service practices and differences in road characteristics and climate. Traction – AA, A, B, C The traction grades, from highest to lowest, are AA, A, B, and C. Those grades represent the tire’s ability to stop on wet pavement as measured under controlled conditions on speciﬁed government test surfaces of asphalt and concrete. A tire marked C may have poor traction performance. Warning: The traction grade assigned to this tire is based on straight-ahead braking traction tests, and does not include acceleration, cornering, hydroplaning, or peak traction characteristics. 5-68 Wheel Alignment and Tire Balance The wheels on your vehicle were aligned and balanced carefully at the factory to give you the longest tire life and best overall performance. If you notice unusual tire wear or your vehicle pulling one way or the other, the alignment may need to be reset. If you notice your vehicle vibrating when driving on a smooth road, your wheels may need to be rebalanced. Temperature – A, B, C The temperature grades are A (the highest), B, and C, representing the tire’s resistance to the generation of heat and its ability to dissipate heat when tested under controlled conditions on a speciﬁed indoor laboratory test wheel. Sustained high temperature can cause the material of the tire to degenerate and reduce tire life, and excessive temperature can lead to sudden tire failure. The grade C corresponds to a level of performance which all passenger car tires must meet under the Federal Motor Vehicle Safety Standard No. 109. Grades B and A represent higher levels of performance on the laboratory test wheel than the minimum required by law. Warning: The temperature grade for this tire is established for a tire that is properly inﬂated and not overloaded. Excessive speed, underinﬂation, or excessive loading, either separately or in combination, can cause heat buildup and possible tire failure. 5-69 Wheel Replacement Replace any wheel that is bent, cracked or badly rusted or corroded. If wheel nuts keep coming loose, the wheel, wheel bolts and wheel nuts should be replaced. If the wheel leaks air, replace it (except some aluminum wheels, which can sometimes be repaired). See your dealer if any of these conditions exist. Your dealer will know the kind of wheel you need. Each new wheel should have the same load-carrying capacity, diameter, width, offset and be mounted the same way as the one it replaces. If you need to replace any of your wheels, wheel bolts or wheel nuts, replace them only with new GM original equipment parts. This way, you will be sure to have the right wheel, wheel bolts and wheel nuts for your vehicle. {CAUTION: Using the wrong replacement wheels, wheel bolts or wheel nuts on your vehicle can be dangerous. It could affect the braking and handling of your vehicle, make your tires lose air and make you lose control. You could have a collision in which you or others could be injured. Always use the correct wheel, wheel bolts and wheel nuts for replacement. Notice: The wrong wheel can also cause problems with bearing life, brake cooling, speedometer or odometer calibration, headlamp aim, bumper height, vehicle ground clearance and tire or tire chain clearance to the body and chassis. See Changing a Flat Tire on page 5-72 for more information. 5-70 Used Replacement Wheels {CAUTION: Putting a used wheel on your vehicle is dangerous. You can’t know how it’s been used or how far it’s been driven. It could fail suddenly and cause a crash. If you have to replace a wheel, use a new GM original equipment wheel. Tire Chains Notice: Use tire chains only where legal and only when you must. Use only SAE Class “S” type chains that are the proper size for your tires. Install them on the rear axle tires and tighten them as tightly as possible with the ends securely fastened. Drive slowly and follow the chain manufacturer’s instructions. If you can hear the chains contacting your vehicle, stop and retighten them. If the contact continues, slow down until it stops. Driving too fast or spinning the wheels with chains on will damage your vehicle. If a Tire Goes Flat It’s unusual for a tire to “blowout” while you’re driving, especially if you maintain your tires properly. If air goes out of a tire, it’s much more likely to leak out slowly. But if you should ever have a “blowout,” here are a few tips about what to expect and what to do: If a front tire fails, the ﬂat tire will create a drag that pulls the vehicle toward that side. Take your foot off the accelerator pedal and grip the steering wheel ﬁrmly. Steer to maintain lane position, and then gently brake to a stop well out of the traffic lane. 5-71 A rear blowout, particularly on a curve, acts much like a skid and may require the same correction you’d use in a skid. In any rear blowout, remove your foot from the accelerator pedal. Get the vehicle under control by steering the way you want the vehicle to go. It may be very bumpy and noisy, but you can still steer. Gently brake to a stop, well off the road if possible. {CAUTION: Lifting a vehicle and getting under it to do maintenance or repairs is dangerous without the appropriate safety equipment and training. The jack provided with your vehicle is designed only for changing a ﬂat tire. If it is used for anything else, you or others could be badly injured or killed if the vehicle slips off the jack. Use the jack provided with your vehicle only for changing a ﬂat tire. If a tire goes ﬂat, the next part shows how to use your jacking equipment to change a ﬂat tire safely. Changing a Flat Tire If a tire goes ﬂat, avoid further tire and wheel damage by driving slowly to a level place. Turn on your hazard warning ﬂashers. {CAUTION: Changing a tire can be dangerous. The vehicle can slip off the jack and roll over or fall on you or other people. You and they could be badly injured or even killed. Find a level place to change your tire. To help prevent the vehicle from moving: 1. Set the parking brake ﬁrmly. 2. Put the shift lever in PARK (P). 3. Turn off the engine and do not restart while the vehicle is raised. 4. Do not allow passengers to remain in the vehicle. CAUTION: (Continued) 5-72 Removing the Spare Tire and Tools CAUTION: (Continued) To be even more certain the vehicle will not move, you should put blocks at the front and rear of the tire farthest away from the one being changed. That would be the tire, on the other side, at the opposite end of the vehicle. When you have a ﬂat tire, use the following example as a guide to assist you in the placement of wheel blocks. The jacking equipment you’ll need is stored by your vehicle’s rear doors, along the passenger’s side wall. 1. Remove the jack cover by pulling it away from the side wall and down to release the tabs securing the top of the cover. The following information will tell you next how to use the jack and change a tire. 5-73 If you remove or restow a tire from/to Notice: the storage position under the vehicle when it is supported by a jack, you could damage the tire and/or your vehicle. Always remove or restow a tire when the vehicle is on the ground. 2. Remove the wheel blocks by turning the top nut counterclockwise. Remove the nut and washer, then pull the wheel blocks off the bolt. 3. Push down on the bolt and remove the hooked end from the slot. Slide the jack toward the front of the vehicle and lift it from the mounting. Remove the extension and the ratchet from the pouch. Your compact spare tire is stored underneath the rear of your vehicle. You will use the ratchet and extension to lower the compact spare tire. 5-74 The ratchet has an UP side. 5. Put the ﬂat end of the extension on an angle through the hole in the rear door frame, above the bumper. Be sure the ﬂat end connects into the hoist shaft. It also has a DOWN side. 4. Attach the ratchet to the extension, with the DOWN side facing you. The extension has a socket end and a ﬂat chisel end. 6. Turn the ratchet counterclockwise to lower the compact spare tire to the ground. Keep turning the ratchet until the spare tire can be pulled out from under the vehicle. 5-75 7. Tilt the retainer plate at the end of the cable, when the tire has been lowered, and pull it through the wheel opening. If you drive away before the spare tire or 8. Pull the tire out from under the vehicle. Notice: secondary latch system cable has been reinstalled, you could damage your vehicle. Always reinstall this cable before driving your vehicle. The tools you’ll be using include the jack (A), wheel blocks (B), extension (C) and ratchet (D). Removing the Flat Tire and Installing the Spare Tire If your vehicle has plastic wheel nut caps, loosen them by turning the wheel wrench counterclockwise. The wheel nut caps are designed to remain with the center cap. Remove the center cap. 5-76 If the wheel has a smooth center piece, place the chisel end of the wheel wrench in the slot on the wheel and gently pry it out. 1. Before you start, block the front and rear of the tire farthest away from the one being changed. Then put your compact spare tire near the ﬂat tire. 2. With the DOWN side facing you, turn the ratchet and socket to loosen all the wheel nuts counterclockwise. Don’t remove them yet. 3. Attach the socket end of the extension to the jack bolt. {CAUTION: Getting under a vehicle when it is jacked up is dangerous. If the vehicle slips off the jack you could be badly injured or killed. Never get under a vehicle when it is supported only by a jack. {CAUTION: Raising your vehicle with the jack improperly positioned can damage the vehicle and even make the vehicle fall. To help avoid personal injury and vehicle damage, be sure to ﬁt the jack lift head into the proper location before raising the vehicle. 4. Attach the ratchet to the extension with the UP side facing you. 5. Turn the ratchet clockwise. That will raise the jack lift head a little. 5-77 6. Position the jack under the vehicle. Use the above diagram to locate the general positions for placing the jack. Front Position A. Front Jack Location B. Jack C. Ratchet and Extension 5-78 Rear Position A. Rear Jack Location B. Jack C. Ratchet and Extension 7. Raise the vehicle by turning the ratchet clockwise. Make sure the UP mark faces you. Raise the vehicle far enough off the ground so there is enough room for the compact spare tire to ﬁt underneath the wheel well. 5-79 8. Remove all the wheel nuts and take off the ﬂat tire. {CAUTION: Rust or dirt on the wheel, or on the parts to which it is fastened, can make the wheel nuts become loose after a time. The wheel could come off and cause an accident. When you change a wheel, remove any rust or dirt from the places where the wheel attaches to the vehicle. In an emergency, you can use a cloth or a paper towel to do this; but be sure to use a scraper or wire brush later, if you need to, to get all the rust or dirt off. 9. Remove any rust or dirt from the wheel bolts, mounting surfaces and spare wheel. {CAUTION: Never use oil or grease on studs or nuts. If you do, the nuts might come loose. Your wheel could fall off, causing a serious accident. 10. Put on the compact spare tire on the mounting surface. 5-80 11. Put the nuts on by hand. Make sure the cone-shaped end is toward the wheel. Tighten each nut by hand until the wheel is held against the hub. If a nut cannot be turned by hand, use the extension and see your dealer as soon as possible. {CAUTION: Incorrect wheel nuts or improperly tightened wheel nuts can cause the wheel to come loose and even come off. This could lead to an accident. Be sure to use the correct wheel nuts. If you have to replace them, be sure to get new GM original equipment wheel nuts. Stop somewhere as soon as you can and have the nuts tightened with a torque wrench to the proper torque speciﬁcation. See Capacities and Speciﬁcations on page 5-101 for wheel nut torque speciﬁcation. 12. Lower the vehicle by turning the ratchet counterclockwise. Lower the jack completely. 5-81 Improperly tightened wheel nuts can lead Notice: to brake pulsation and rotor damage. To avoid expensive brake repairs, evenly tighten the wheel nuts in the proper sequence and to the proper torque speciﬁcation. See Capacities and Speciﬁcations on page 5-101 for the wheel nut torque speciﬁcation. 13. Tighten the wheel nuts ﬁrmly in a crisscross sequence as shown. Turn the ratchet clockwise with the UP mark facing you. 14. Remove the wheel blocks. Notice: Wheel covers will not ﬁt on your compact spare. If you try to put a wheel cover on the compact spare, you could damage the cover or the spare. Do not try to put a wheel cover, center cap, or lug nut caps on your compact spare tire. They will not ﬁt. Store the wheel cover, center cap, or lug nut caps in the trunk until you have the ﬂat tire repaired or replaced. Storing a Flat or Spare Tire and Tools {CAUTION: Storing a jack, a tire, or other equipment in the passenger compartment of the vehicle could cause injury. In a sudden stop or collision, loose equipment could strike someone. Store all these in the proper place. To store a ﬂat tire, do the following: 1. Put the ﬂat tire on the ground at the rear of the vehicle with the valve stem pointed down. 2. Tilt the retainer plate downward and through the wheel opening. Make sure it is fully seated across the underside of the wheel. Attach the ratchet, with the UP side facing you, to the extension. 5-82 3. Put the ﬂat end of the extension on an angle through the hole in the rear door frame, above the bumper. The compact spare is for temporary use only. Replace the compact spare tire with a full-size tire as soon as you can. See Compact Spare Tire on page 5-84. See the storage instructions label to restore your compact spare properly. 4. Raise the tire fully against the underside of the vehicle by turning the ratchet/wheel wrench until you hear two clicks or feel it skip twice. The spare tire hoist cannot be overtightened. 5. Make sure the tire is stored securely. Push and pull (A), and then try to turn (B) the tire. If the tire moves, use the ratchet/wheel wrench to tighten the cable. 6. Return the jacking equipment to its proper location. 5-83 Compact Spare Tire Although the compact spare tire was fully inﬂated when your vehicle was new, it can lose air after a time. Check the inﬂation pressure regularly. It should be 60 psi (420 kPa). After installing the compact spare on your vehicle, you should stop as soon as possible and make sure your spare tire is correctly inﬂated. The compact spare is made to perform well at speeds up to 65 mph (105 km/h) for distances up to 3,000 miles (5 000 km), so you can ﬁnish your trip and have your full-size tire repaired or replaced where you want. Of course, it’s best to replace your spare with a full-size tire as soon as you can. Your spare will last longer and be in good shape in case you need it again. Notice: When the compact spare is installed, do not take your vehicle through an automatic car wash with guide rails. The compact spare can get caught on the rails. That can damage the tire and wheel, and maybe other parts of your vehicle. Don’t use your compact spare on other vehicles. And don’t mix your compact spare tire or wheel with other wheels or tires. They won’t ﬁt. Keep your spare tire and its wheel together. Notice: Tire chains will not ﬁt your compact spare. Using them can damage your vehicle and can damage the chains too. Do not use tire chains on your compact spare. Appearance Care Cleaning products can be hazardous. Some are toxic. Other cleaning products can burst into ﬂames if a match is struck near them or if they get on a hot part of the vehicle. Some are dangerous if their fumes are inhaled in a closed space. When anything from a container is used to clean the vehicle, be sure to follow the manufacturer’s warnings and instructions. Always open the doors or windows of the vehicle when cleaning the inside. Never use these to clean the vehicle: (cid:127) Gasoline (cid:127) Benzene (cid:127) Naphtha (cid:127) Carbon Tetrachloride (cid:127) Acetone (cid:127) Paint Thinner Turpentine 5-84 (cid:127) Lacquer Thinner (cid:127) Nail Polish Remover They can all be hazardous — some more than others — and they can all damage the vehicle, too. Do not use any of these products unless this manual says you can. In many uses, these will damage the vehicle: (cid:127) Alcohol Laundry Soap (cid:127) Bleach (cid:127) Reducing Agents Fabric/Carpet Use a vacuum cleaner often to get rid of dust and loose dirt. Wipe vinyl, leather, plastic, and painted surfaces with a clean, damp cloth. GM-approved cleaning products can be obtained from your dealer. Here are some cleaning tips: (cid:127) Always read the instructions on the cleaner label. (cid:127) Clean up stains as soon as you can before they set. (cid:127) Carefully scrape off any excess stain. (cid:127) Use a clean cloth or sponge, and change to a clean area often. A soft brush may be used if stains are stubborn. To avoid forming a ring on fabric after spot cleaning, clean the entire area immediately or it will set. Most stains can be removed with club soda water. To clean, use the following instructions: 1. For liquids: blot with a clean, soft, white cloth. For solids: remove as much as possible and then vacuum or brush. 2. Apply club soda water to a clean, soft, white cloth. Do not over-saturate; the cloth should not drip water. 3. Clean the entire area. Avoid getting the fabric too wet. 4. Start cleaning from the seams into the stain to avoid a ring effect. 5. Continue cleaning, using a clean area of the cloth each time it becomes soiled. 6. When the stain is removed, blot the cleaned area with another dry, clean, soft, white cloth. 5-85 (cid:127) (cid:127) (cid:127) Using Cleaner on Fabric 1. First, try the cleaner on an area of the fabric that is not easily seen to make sure the cleaner does not affect the color of the fabric. 2. For liquids: blot with a clean, soft, white cloth. For solids: remove as much as possible and then vacuum or brush. 3. Spray a small amount of the cleaner onto a clean soft, white, cloth. Do not apply spray directly to the fabric. 4. Start cleaning from the seams into the stain to avoid a ring effect. 5. Continue cleaning, using a clean area of the cloth each time it becomes soiled. 6. When the stain is removed, blot the cleaned area with another dry, clean, soft, white cloth. 7. If the cleaner leaves a ring effect, follow up with the club soda water instructions given earlier in this section. Special Fabric Cleaning Problems Stains caused by such things as catsup, black coffee, egg, fruit, fruit juice, milk, soft drinks, vomit, urine, and blood can be removed using the club soda water instructions given earlier in this section. If an odor lingers after cleaning vomit or urine, treat the area with a water and baking soda solution: 1 teaspoon (5 ml) of baking soda to 1 cup (250 ml) of lukewarm water. Let dry. Stains caused by oil and grease can be cleaned with an approved GM cleaner and a clean, white cloth. 1. Carefully scrape off excess stain. 2. Clean with cool water and allow to dry completely. 3. If a stain remains, follow the “Using Cleaner on Fabric” instructions described earlier. Vinyl Use warm water and a clean cloth. (cid:127) Rub with a clean, damp cloth to remove dirt. This may have to be done more than once. Things like tar, asphalt, and shoe polish will stain if they are not removed quickly. Use a clean cloth and vinyl cleaner. See your dealer for this product. 5-86 (cid:127) Leather Use a soft cloth with lukewarm water and a mild soap or saddle soap and wipe dry with a soft cloth. Then, let the leather dry naturally. Do not use heat to dry. For stubborn stains, use a leather cleaner. (cid:127) Never use oils, varnishes, solvent-based or abrasive cleaners, furniture polish, or shoe polish on leather. (cid:127) Soiled or stained leather should be cleaned immediately. If dirt is allowed to work into the ﬁnish, it can harm the leather. Glass Surfaces Glass should be cleaned often. GM Glass Cleaner or a liquid household glass cleaner will remove normal tobacco smoke and dust ﬁlms on interior glass. See Vehicle Care/Appearance Materials on page 5-92. Notice: cleaning glass surfaces on your vehicle, you could scratch the glass and/or cause damage to the rear window defogger and the integrated radio antenna. When cleaning the glass on your vehicle, use only a soft cloth and glass cleaner. If you use abrasive cleaners when Instrument Panel Use only mild soap and water to clean the top surfaces of the instrument panel. Sprays containing silicones or waxes 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: Interior Plastic Components Use only a mild soap and water solution on a soft cloth or sponge. Commercial cleaners may affect the surface ﬁnish. Do not bleach or dye safety belts. If you do, 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. 5-87 (cid:127) 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. Washing Your Vehicle The paint ﬁnish on the vehicle provides beauty, depth of color, gloss retention, and durability. The best way to preserve the vehicle’s ﬁnish is to keep it clean by washing it often with lukewarm or cold water. Do not wash the vehicle in the direct rays of the sun. Use a car washing soap. Do not use strong soaps or chemical detergents. Be sure to rinse the vehicle well, removing all soap residue completely. GM-approved cleaning products can be obtained from your dealer. See Vehicle Care/Appearance Materials on page 5-92. Do not use cleaning agents that are petroleum based, or that contain acid or abrasives. All cleaning agents should be ﬂushed promptly and not allowed to dry on the surface, or they could stain. Dry the ﬁnish with a soft, clean chamois or an all-cotton towel to avoid surface scratches and water spotting. If you drive your vehicle through an Notice: automatic car wash that does not have enough clearance for the wide rear tires and wheels, you could damage your vehicle. Verify with the manager of the car wash that your vehicle will ﬁt before entering the car wash or use a touchless car wash. High pressure car washes may cause water to enter the vehicle. 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. 5-88 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. Windshield 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 glass cleaning liquid or powder and water solution. The windshield is clean if beads do not form when it is rinsed 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. 5-89 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. 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. If you drive your vehicle through an 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. 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. 5-90 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.

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 8th 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 front passenger door frame. 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 air bag system. Before attempting to add anything electrical to your vehicle, see Servicing Your Airbag-Equipped Vehicle on page 1-69. Headlamp Wiring The headlamp wiring is protected by a circuit breaker in the lamp switch. An electrical overload will cause the lamps to ﬂicker on and off, or in some cases to remain 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, etc., the wiper will stop until the motor cools. Although the circuit is protected from electrical overload, overload due to heavy snow, etc., may cause wiper linkage damage. Always clear ice and heavy snow from the windshield before using the windshield wipers. If the overload is caused by some electrical problem and not snow, etc., be sure to get it ﬁxed. Power Windows and Other Power Options Circuit breakers in the fuse panel 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 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. Spare fuses and a fuse puller are located in the underhood fuse block. You can remove fuses with the fuse puller. Remember to replace any of the spare fuses you use, so you will have some if you ever need them again. If you ever have a problem on the road and do not 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. There are two fuse blocks in your vehicle: one is inside the vehicle and one is in the engine compartment. 5-95 Instrument Panel Fuse Block The fuse block is located on the lower portion of the instrument panel on the driver’s side.

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 Maintenance intervals, checks, inspections 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. 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 How This Section is Organized This maintenance schedule is divided into ﬁve parts: “Part A: Scheduled Maintenance Services” explains what to have done and how often. Some of these services can be complex, so unless you are technically qualiﬁed and have the necessary equipment, you should let your GM dealer’s service department do these jobs. Your GM dealer has GM-trained and supported service people that will perform the work using genuine GM parts. {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, have a qualiﬁed technician do the work. If you want to get the service information, see Service Publications Ordering Information on page 7-12. “Part B: Owner Checks and Services” tells you what should be checked and when. It also explains what you can easily do to help keep your vehicle in good condition. “Part C: Periodic Maintenance Inspections” explains important inspections that your dealer’s service department can perform for you. “Part D: Recommended Fluids and Lubricants” lists some recommended products necessary to help keep your vehicle properly maintained. These products, or their equivalents, should be used whether you do the work yourself or have it done. “Part E: Maintenance Record” is a place for you to record and keep track of the maintenance performed on your vehicle. Keep your maintenance receipts. They may be needed to qualify your vehicle for warranty repairs. 6-3 Part A: Scheduled Maintenance Services In this part are scheduled maintenance services which are to be performed at the mileage intervals speciﬁed. Using Your Maintenance Schedule We at General Motors want to help you to keep your vehicle in good working condition. But we do not know exactly how you will drive it. You may drive 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 dealer. This part tells you the maintenance services you should have done and when to schedule them. When you go to your dealer for your service needs, you will know that GM-trained and supported service people will perform the work using GM parts. The proper ﬂuids and lubricants to use are listed in Part D. Make sure whoever services your vehicle uses them. All parts should be replaced and all necessary repairs done before you or anyone else drives the vehicle. These schedules are 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 4-28. are driven on reasonable road surfaces within driving limits. use the recommended fuel. See Gasoline Octane on page 5-5. 6-4 (cid:127) (cid:127) (cid:127) Selecting the Right Schedule First you will need to decide which of the two schedules is right for your vehicle. Here is how to decide which schedule to follow: Short Trip/City Deﬁnition Follow the Short Trip/City Scheduled Maintenance if any one of these conditions is true for your vehicle: (cid:127) Most trips are less than 5 miles (8 km). This is particularly important when outside temperatures are below freezing. (cid:127) Most trips include extensive idling, such as frequent driving in stop-and-go traffic. (cid:127) You frequently tow a trailer or use a carrier on top of your vehicle. If the vehicle is used for delivery service, police, taxi, or other commercial application. One of the reasons you should follow this schedule if you operate your vehicle under any of these conditions is that these conditions cause engine oil to break down sooner. Short Trip/City Intervals Every 3,000 Miles (5 000 km): Engine Oil and Filter Change (or 3 months, whichever occurs ﬁrst). Chassis Lubrication (or 3 months, whichever occurs ﬁrst). Every 6,000 Miles (10 000 km): Tire Rotation. Every 15,000 Miles (25 000 km): Engine Air Cleaner Filter Inspection. Front Wheel Bearing Repack (two–wheel drive only) (or at each brake relining, whichever occurs ﬁrst). Automatic Transmission Service (severe conditions only). Every 30,000 Miles (50 000 km): Fuel Filter Replacement. Every 45,000 Miles (75 000 km): Engine Air Cleaner Filter Replacement. Every 50,000 Miles (83 000 km): Automatic Transmission Service (normal conditions). Transfer Case Fluid Change. Every 100,000 Miles (166 000 km): Spark Plug Wire Inspection. Spark Plug Replacement. Positive Crankcase Ventilation (PCV) Valve Inspection. 6-5 (cid:127) Every 150 000 Miles (240 000 km): Cooling System Service (or every 60 months, whichever occurs ﬁrst). Engine Accessory Drive Belt Inspection. These intervals only summarize maintenance services. Be sure to follow the complete scheduled maintenance on the following pages. Long Trip/Highway Deﬁnition Follow this scheduled maintenance only if none of the conditions from the Short Trip/City Scheduled Maintenance are true. Do not use this schedule if the vehicle is used for trailer towing, driven in a dusty area, or used off paved roads. Use the Short Trip/City schedule for these conditions. Driving a vehicle with a fully warmed engine under highway conditions will cause engine oil to break down slower. Long Trip/Highway Intervals Every 7,500 Miles (12 500 km): Engine Oil and Filter Change (or every 12 months, whichever occurs ﬁrst). Chassis Lubrication (or 12 months, whichever occurs ﬁrst). Tire Rotation. Every 15,000 Miles (25 000 km): Engine Air Cleaner Filter Inspection. Automatic Transmission Service (severe conditions only). Every 30,000 Miles (50 000 km): Fuel Filter Replacement. Front Wheel Bearing Repack (two–wheel drive only) (or at each brake relining, whichever occurs ﬁrst). Every 45,000 Miles (75 000 km): Engine Air Cleaner Filter Replacement. Every 50,000 Miles (83 000 km): Automatic Transmission Service (normal conditions). Transfer Case Fluid Change. Every 100,000 Miles (166 000 km): Spark Plug Wire Inspection. Spark Plug Replacement. Positive Crankcase Ventilation (PCV) Valve Inspection. Every 150,000 Miles (240 000 km): Cooling System Service (or every 60 months, whichever occurs ﬁrst). Engine Accessory Drive Belt Inspection. These intervals only summarize maintenance services. Be sure to follow the complete scheduled maintenance on the following pages. 6-6 Short Trip/City Scheduled Maintenance The services shown in this schedule up to 100,000 miles (166 000 km) should be repeated after 100,000 miles (166 000 km) at the same intervals for the life of this vehicle. The services shown at 150,000 miles (240 000 km) should be repeated at the same interval after 150,000 miles (240 000 km) for the life of this vehicle. See Part B: Owner Checks and Services on page 6-24 and Part C: Periodic Maintenance Inspections on page 6-28. Footnotes † The U.S. Environmental Protection Agency or the California Air Resources Board has determined that the failure to perform this maintenance item will not nullify the emission warranty or limit recall liability prior to the completion of the vehicle’s useful life. We, however, urge that all recommended maintenance services be performed at the indicated intervals and the maintenance be recorded. # Lubricate the front suspension, ball joints and kingpin bushings, steering linkage, parking brake cable guides and brake pedal springs. + A good time to check your brakes is during tire rotation.
