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 5-69. 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 4-52. 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 original equipment tire size and recommended inﬂation pressure. See Loading Your Vehicle on page 4-52. 5-64 Inﬂation - Tire Pressure The tire and loading information label, shows the correct inﬂation pressures for your tires when they’re cold. “Cold” means your vehicle has been sitting for at least three hours or driven no more than 1 mile (1.6 km). See Loading Your Vehicle on page 4-52, for the location of your vehicle’s tire and loading information label. Notice: Don’t let anyone tell you that underinﬂation or overinﬂation is all right. It’s not. If your tires don’t have enough air (underinﬂation), you can get the following: Too much ﬂexing Too much heat Tire overloading (cid:127) Bad wear (cid:127) Bad handling (cid:127) Bad fuel economy If your tires have too much air (overinﬂation), you can get the following: (cid:127) Unusual wear (cid:127) Bad handling (cid:127) Rough ride (cid:127) Needless damage from road hazards (cid:127) (cid:127) (cid:127) 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 5-67 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 wheel wrench to tighten the cable. See Changing a Flat Tire on page 5-74. 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 Scheduled Maintenance on page 6-4. When to Check Check your tires once a month or more. Also, check the tire pressure of the spare tire. If you have a compact spare tire, it should be at 60 psi (420 kPa). How to Check Use a good quality pocket-type gage to check tire pressure. You can’t tell if your tires are properly inﬂated simply by looking at them. Radial tires may look properly inﬂated even when they’re underinﬂated. 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 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. Recheck 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. 5-65 After the tires have been rotated, adjust the front and rear inﬂation pressures as shown on the Tire and Loading Information label. For the location of the tire and loading information label see Loading Your Vehicle on page 4-52. Make certain that all wheel nuts are properly tightened, see “Wheel Nut Torque” under Capacities and Speciﬁcations on page 5-108 for the proper wheel nut torque speciﬁcation. {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” in the Index. When rotating your tires, always use one of the correct rotation patterns shown here. If your vehicle has a compact spare tire or a spare tire that does not match your vehicle’s road tires and wheels, in size and type, do not include the spare in the tire rotation. 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. 5-67 (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 4-52, for examples of these 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 (if you have one). It was developed for use on your vehicle. {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. 5-68 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. 5-69 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. 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. Scheduled wheel alignment and wheel balancing are not needed. However, 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. 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. 5-70 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 5-74 for more information. 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. 5-71 Tire Chains {CAUTION: If your vehicle has P225/75R15, P265/75R15 or P235/50R17 size tires, do not use tire chains. They can damage your vehicle because there is not enough clearance. Tire chains used on a vehicle without the proper amount of clearance can cause damage to the brakes, suspension or other vehicle parts. The area damaged by the tire chains could cause you to lose control of your vehicle and you or others may be injured in a crash. Use another type of traction device only if its manufacturer recommends it for use on your vehicle and tire size combination and road conditions. Follow that manufacturer’s instructions. To help avoid damage to your CAUTION: (Continued) CAUTION: (Continued) vehicle, drive slowly, readjust or remove the device if it is contacting your vehicle, and don’t spin your wheels. If you do ﬁnd traction devices that will ﬁt, install them on the rear tires. Notice: If your vehicle has a tire size other than P225/75R15, P265/75R15 or P235/50R17, use tire chains only where legal and only when you must. Use chains that are the proper size for your tires. Install them on the tires of the rear axle. Do not use chains on the tires of the front axle. 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. 5-72 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. 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. 5-73 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. See Hazard Warning Flashers on page 3-4 for more information. {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 an automatic transmission shift lever in PARK (P), or shift a manual transmission to FIRST (1) or REVERSE (R). 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) 5-74 CAUTION: (Continued) Put the wheel 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. The following steps will tell you how to use the jack and change a tire. Removing the Spare Tire and Tools The tools you will need are under the passenger’s seat. For crew cab models, the jack and wheel blocks are under the driver’s side rear seat. For regular and extended cab vehicles the jack and wheel blocks are located under the cover at the center of the vehicle behind the front seats. 1. The vehicle will have a cover if it is an extended or regular cab. Crew Cab Regular and Extended Cab 5-75 You will use the jack handle extensions and the wheel wrench to remove the underbody-mounted spare tire. A. Jack Handle Extensions B. Bottle Jack C. Extension Tool D. Wheel Wrench E. Wheel Blocks 1. Assemble the wheel wrench (D) and the jack handle extensions (A) as shown. 2. Move the seats forward and turn the wing nut on the cover counterclockwise to remove it. For crew cab models, reach under the rear seat to access the jack and wheel blocks. To reinstall the jack and wheel block assembly in the mounting bracket, insert the tabs into the jack base by pushing the blocks up into the assembly. The outer hole in the jack base aligns with the tab on the bracket. When reinstalling, make sure the jack is secure, but do not overtighten the jack in the bracket. 3. The wheel blocks and the wheel block retainer can be removed by turning the wing nut counterclockwise. Put the wheel 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. 4. There is also a wing nut used to retain the storage bag and tools located under the front passenger’s seat. To remove it, turn the wing nut counterclockwise. 5-76 4. When the tire has been lowered, tilt the retainer and slide it up the cable so it can be pulled up through the wheel opening. 5. Put the spare tire near the ﬂat tire. 5-77 2. Insert the hoist end (chiseled end) of the extension tool through the hole in the rear bumper and into the funnel-shaped guide. The chiseled end of the extension is used to lower the spare tire. 3. Turn the wheel wrench (D) counterclockwise to lower the spare tire to the ground. Continue to turn the wheel wrench until the spare tire can be pulled out from under the vehicle. If the spare tire does not lower to the ground, the secondary latch is engaged causing the tire not to lower. See “Secondary Latch System” later in this section. Removing the Flat Tire and Installing the Spare Tire Use the following pictures and instructions to remove the ﬂat tire and raise the vehicle. The tools you will be using include the bottle jack (A), the wheel blocks (B), the extension tool (C), the jack handle extensions (D), and the wheel wrench (E). 5-78 1. Remove the center cap by placing the chisel end of the wheel wrench (E) in the slot on the wheel and gently prying the cap out. 2. Use the wheel wrench to loosen all the wheel nuts. Turn the wheel wrench counterclockwise to loosen the wheel nuts. Do not remove the wheel nuts yet. Front Location 5-79 Front Location Rear Location 3. Position the jack (A) under the vehicle as shown. 5-80 Front Location If the ﬂat tire is on the front of the vehicle, position the jack to the rear of the front tire in the pocket off of the frame. If the ﬂat tire is on the rear, position the jack under the rear axle and get as close as possible to the shock absorber. {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. 5-81 6. Remove all the wheel nuts and take off the ﬂat tire. 7. Remove any rust or dirt from the wheel bolts, mounting surfaces and spare wheel. Rear Position 4. Make sure the jack head is positioned so that the rear axle is resting securely between the grooves that are on the jack head. 5. Turn the wheel wrench clockwise to raise the vehicle. Raise the vehicle far enough off the ground so there is enough room for the spare tire to ﬁt under the wheel well. 5-82 {CAUTION: {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. 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. 8. After mounting the spare, put the wheel nuts back on with the rounded end of the nuts toward the wheel. Tighten each wheel nut by hand. Then use the wheel wrench to tighten the nuts until the wheel is held against the hub. 5-83 Front Position Rear Position 9. Turn the wheel wrench counterclockwise to lower the vehicle. Lower the jack completely. 5-84 10. Tighten the wheel nuts ﬁrmly in a crisscross sequence as shown by turning the wheel wrench clockwise. {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. CAUTION: (Continued) CAUTION: (Continued) 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” in the Index for wheel nut torque speciﬁcation. 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” in the index for the wheel nut torque speciﬁcation. When you reinstall the regular wheel and tire, you must also reinstall the center cap. Place the cap on the wheel and tap it into place until it seats ﬂush with the wheel. The cap only goes on one way. Be sure to line up the tab on the center cap with the indentation on the wheel. 5-85 Store the tire under the rear of the vehicle in the spare tire carrier. Use the art and text following to help you. 1. Put the tire on the ground at the rear of the vehicle with the valve stem pointed down. Storing a Flat or Spare Tire, Jack 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. Notice: Storing an aluminum wheel with a ﬂat tire under your vehicle for an extended period of time or with the valve stem pointing up may damage the wheel. Always stow the wheel with the valve stem pointing down and have the wheel/tire repaired as soon as possible. 5-86 3. Attach the wheel wrench and extensions together. 2. Tilt the retainer downward and through the wheel opening. Make sure the retainer is fully seated across the underside of the wheel. 5-87 4. Insert the hoist end through the hole in the rear bumper and into the funnel-shaped guide. 5. Turn the wheel wrench clockwise to raise the tire part way up. Make sure the retainer is seated in the wheel opening and the valve stem is pointed down. 6. Raise the tire fully against the underside of the vehicle by turning the wheel wrench clockwise until you feel it skip twice. You cannot overtighten the cable. A. Push and Pull on Tire B. Turn Tire 7. Make sure the tire is stored securely. Push, pull, and then try to turn the tire. If the tire moves, check to make sure the tire valve stem is pointing down, then use the wheel wrench to loosen and then tighten the cable. 5-88 Return the wheel wrench and jack extensions and the storage bag to the location under the front passenger’s seat. Reinstall the jack and wheel blocks, be sure to install the wheel blocks ﬁrst. Secure the items in the vehicle as shown. A. Bottle Jack B. Wheel Blocks C. Wing Nut Regular and Extended Cab Crew Cab A. Bottle Jack B. Wheel Blocks C. Wing Nut 5-89 Secondary Latch System Your vehicle has an underbody mounted tire hoist assembly equipped with a secondary latch system. It is designed to stop the spare tire from suddenly falling off your vehicle. For the secondary latch to work, the spare must be installed with the valve stem pointing down. See “Storing a Flat or Spare Tire, Jack and Tools” earlier in this section. {CAUTION: Before beginning this procedure read all the instructions. Failure to read and follow the instructions could damage the hoist assembly and you and others could get hurt. Read and follow the instructions listed below. 5-90 To release the spare tire from the secondary latch do the following: 1. Check under the vehicle to see if the cable end ﬁtting is visible. 2. If the cable end ﬁtting is not visible proceed to Step 6. If it is visible, ﬁrst try to tighten the cable by turning the wheel wrench clockwise until you hear two clicks or feel it skip twice. You cannot overtighten the cable. 3. Loosen the cable by turning the wheel wrench counterclockwise three or four turns. 4. Repeat this procedure at least two times. If the spare tire lowers to the ground, continue with Step 5 of “Removing the Spare Tire and Tools” earlier in this section. 5. Turn the wrench counterclockwise until approximately six inches (15 cm) of cable is exposed. 6. Stand the wheel blocks on their shortest ends, with the backs facing each other. 7. Place the bottom edge of the jack on the wheel blocks, separating them so that the jack is balanced securely. 8. Attach the jack handle, extension, and wheel wrench to the jack and place it (with the wheel blocks) under the vehicle towards the front of the rear bumper. Position the center lift point of the jack under the wheel. 9. Turn the wrench clockwise to raise the jack until it lifts the tire. 10. Continue raising the jack until the tire stops moving upward and is held ﬁrmly in place. The secondary latch has released and the tire is balancing on the jack. 5-91 {CAUTION: Someone standing too close during the procedure could be injured by the jack. If the spare tire does not slide off the jack completely, make sure no one is behind you or on either side of you as you pull the jack out from the spare. 13. Disconnect the jack handle from the jack and carefully remove the jack. Use one hand to push against the spare while ﬁrmly pulling the jack out from under the spare tire with the other hand. If the spare tire is hanging from the cable, insert the hoist handle, extension and wheel wrench into the hoist shaft hole in the bumper and turn the wheel wrench counterclockwise to lower the spare the rest of the way. 11. Remove the jack handle and insert the hoist end of the extension through the hole in the rear bumper. Turn the wheel counterclockwise one turn or until the wheel retainer assembly falls out. 12. Reinsert the jack handle into the jack. Lower the jack by turning the wheel wrench counterclockwise. Keep lowering the jack until the spare tire slides off the jack or is hanging by the cable. 5-92 Spare Tire Compact Spare Tire Your vehicle may be equipped with a 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. For heavy payloads or towing, and for low traction or four-wheel-drive conditions, repair or replace the full-size tire, and reinstall for best performance. 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, don’t 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. 5-93 14. Tilt the tire retainer at the end of the cable and pull it through the wheel opening. Pull the tire out from under the vehicle. 15. If the cable is hanging under the vehicle, turn the wheel wrench clockwise to raise the cable back up. Have the hoist assembly inspected as soon as you can. You will not be able to store a spare or ﬂat tire using the hoist assembly until it has been replaced. To continue changing the ﬂat tire, see “Removing the Flat Tire and Installing the Spare Tire” earlier in this section. 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 won’t ﬁt your compact spare. Using them can damage your vehicle and can damage the chains too. Don’t use tire chains on your compact spare. Full-Size Spare Tire Your vehicle may be equipped with a full-size spare tire, which, when new, was fully inﬂated. A spare tire, whether compact-size or full-size, may lose air over time, so check its inﬂation pressure regularly. See Inﬂation - Tire Pressure on page 5-64 and Loading Your Vehicle on page 4-52 for information regarding proper tire inﬂation and loading your vehicle. For instruction on how to remove, install or store a spare tire, see Changing a Flat Tire on page 5-74. After installing the spare tire on your vehicle, you should stop as soon as possible and make sure the spare is correctly inﬂated. Have the damaged or ﬂat road tire repaired or replaced as soon as you can and installed back onto your vehicle. This way, a spare tire will be available in case you need it again. Don’t mix tires and wheels of different sizes, because they won’t ﬁt. Keep your spare tire and its wheel together. 5-94 Appearance Care Remember, cleaning products can be hazardous. Some are toxic. Others can burst into ﬂames if you strike a match or get them on a hot part of the vehicle. Some are dangerous if you breathe their fumes in a closed space. When you use anything from a container to clean your vehicle, be sure to follow the manufacturer’s warnings and instructions. And always open your doors or windows when you are cleaning the inside. Never use these to clean your vehicle: (cid:127) Gasoline (cid:127) Benzene (cid:127) Naphtha (cid:127) Carbon Tetrachloride (cid:127) Acetone (cid:127) Paint Thinner Turpentine Lacquer Thinner (cid:127) Nail Polish Remover They can all be hazardous — some more than others — and they can all damage your vehicle, too. (cid:127) (cid:127) Do not use any of these unless this manual says you can. In many uses, these will damage your vehicle: (cid:127) Alcohol Laundry Soap (cid:127) Bleach (cid:127) Reducing Agents Cleaning the Inside of Your Vehicle 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. Cleaning Fabric/Carpet Your dealer has cleaners for the cleaning of fabric and carpet. They will clean normal spots and stains very well. You can get GM- approved cleaning products from your dealer. See Vehicle Care/Appearance Materials on page 5-102. 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. If a ring forms on fabric after spot cleaning, clean the entire area immediately or it will set. Using Cleaner on Fabric 1. Vacuum and brush the area to remove any loose dirt. 2. Always clean a whole trim panel or section. Mask surrounding trim along stitch or welt lines. 3. Follow the directions on the container label. 4. Apply cleaner with a clean sponge. Don’t saturate the material and don’t rub it roughly. 5. As soon as you’ve cleaned the section, use a sponge to remove any excess cleaner. 6. Wipe cleaned area with a clean, water-dampened towel or cloth. 7. Wipe with a clean cloth and let dry. 5-95 (cid:127) (cid:127) Special Fabric Cleaning Problems Stains caused by such things as catsup, coffee (black), egg, fruit, fruit juice, milk, soft drinks, vomit, urine and blood can be removed as follows: 1. Carefully scrape off excess stain, then sponge the soiled area with cool water. 2. If a stain remains, follow the cleaner instructions described earlier. 3. If an odor lingers after cleaning vomit or urine, treat the area with a water/baking soda solution: 1 teaspoon (5 ml) of baking sold to 1 cup (250 ml) of lukewarm water. 4. Let dry. Stains caused by candy, ice cream, mayonnaise, chili sauce and unknown stains can be removed as follows: 1. Carefully scrape off excess stain. 2. First, clean with cool water and allow to dry completely. 3. If a stain remains, follow the cleaner instructions described earlier. Cleaning Vinyl Use warm water and a clean cloth. (cid:127) Rub with a clean, damp cloth to remove dirt. You may have to do this more than once. Things like tar, asphalt and shoe polish will stain if you don’t get them off quickly. Use a clean cloth and vinyl cleaner. See your dealer for this product. Cleaning 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. 5-96 (cid:127) (cid:127) Cleaning the Top of the 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. Cleaning Interior Plastic Components Use only a mild soap and water solution on a soft cloth or sponge. Commercial cleaners may affect the surface ﬁnish. Cleaning 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 5-102. Notice: 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 cleaning Care of Safety Belts Keep belts clean and dry. {CAUTION: 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. Weatherstrips Silicone grease on weatherstrips will make them last longer, seal better, and not stick or squeak. Apply silicone grease with a clean cloth at least every six months. During very cold, damp weather more frequent application may be required. See Recommended Fluids and Lubricants on page 6-13. 5-97 Cleaning the Outside of Your Vehicle The paint ﬁnish on your vehicle provides beauty, depth of color, gloss retention and durability. Washing Your Vehicle The best way to preserve your vehicle’s ﬁnish is to keep it clean by washing it often with lukewarm or cold water. Do not wash your 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. You can get GM-approved cleaning products from your dealer. See Vehicle Care/Appearance Materials on page 5-102. 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. High pressure car washes may cause water to enter your 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.” 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 5-102. 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. 5-98 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. Cleaning the 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 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. 5-99 Cleaning Aluminum Wheels Keep your 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. The surface of these wheels is similar to the painted surface of your vehicle. Do not use strong soaps, chemicals, abrasive polishes, abrasive cleaners, cleaners with acid, or abrasive cleaning brushes on them because you could damage the surface. Do not use chrome polish on aluminum wheels. Do not take your vehicle through an automatic car wash that has silicone carbide tire cleaning brushes. These brushes can also damage the surface of these wheels. Cleaning Tires To clean your 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 your 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 avaliable from your dealer. Larger areas of ﬁnish damage can be corrected in your dealer’s body and paint shop. 5-100 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 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 your 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. 5-101 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 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 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. 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 Air Bag-Equipped Vehicle on page 1-72. 5-103 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. Power and Heated Seat Circuit Breakers There is a circuit breaker located underneath the driver’s side front seat that controls the power and heated seat functions. 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 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. 5-104 Engine Compartment Fuse Block The engine compartment fuse block is located on the driver’s side of the engine compartment. See Engine Compartment Overview on page 5-12 for more information on location of the engine compartment fuse block. To remove the cover, push in on the tab on the end of the cover and lift. To reinstall the cover, line up the tab and push down on the cover until the tab clicks into place.

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 4-52. 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 6-4 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 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. 6-3 (cid:127) (cid:127) (cid:127) (cid:127) 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 get service information, see Service Publications Ordering Information on page 7-11. Owner Checks and Services on page 6-9 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 6-13 and Normal Maintenance Replacement Parts on page 6-15. 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. Scheduled Maintenance When the CHANGE 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 on page 5-13 for information on the Engine Oil Life System and resetting the system. When the CHANGE 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. 6-4 Maintenance I — Use Maintenance I if the CHANGE OIL light comes on within ten months since 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 ten months or more since the last service or if the light has not come on at all for one year. Scheduled Maintenance Service Maintenance I Maintenance II Change engine oil and ﬁlter. Reset oil life system. See Engine Oil on page 5-13. An Emission Control Service.

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 drum brake linings for wear or cracks. Inspect disc brake pads for wear and rotors for surface condition. Inspect other brake parts, including drums, wheel cylinders, calipers, parking brake, etc. Check parking brake adjustment. (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. Visually check constant velocity joints, rubber boots and axle seals for leaks. (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 air bag coverings, and have them repaired or replaced. (The air bag system does not need regular maintenance.) 6-7 (f) Lubricate all key lock cylinders, body door and fuel door hinges, latches and locks (including glove box and console doors), hood latch assembly, secondary latch, pivots, spring anchor, release pawl and any moving seat hardware. Lubricate hood safety lever pivot and prop rod pivot and tailgate latch bolt, handle assembly pivot points and hinges. 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) 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. (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. See Engine Coolant on page 5-25 for what to use. Inspect hoses. Clean radiator, condenser, pressure cap and ﬁller neck. Pressure test the cooling system and pressure cap. 6-8 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 6-13. 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 5-13 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 Engine Coolant Level Check Check the engine coolant level and add DEX-COOL® coolant mixture if necessary. See Engine Coolant on page 5-25 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 5-57 for further details. Check to make sure the spare tire is stored securely. Push, pull and then try to rotate or turn the spare tire. If it moves, tighten it. See Changing a Flat Tire on page 5-74. 6-9 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 2-29 if necessary. Do not use the accelerator pedal, and be ready to turn off the engine immediately if it starts. 3. On automatic transmission vehicles, 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. On manual transmission vehicles, put the shift lever in NEUTRAL (N), push the clutch down halfway and try to start the engine. The starter should work only when the clutch is pushed down all the way to the ﬂoor.
