A ﬂuid loss could indicate a problem. Have it inspected and repaired. Refer to the Maintenance Schedule to determine how often to check the lubricant and when to change it. See Part A: Scheduled Maintenance Services on page 6-4. To get an accurate reading, the vehicle should be on a level surface. If the level is below the bottom of the ﬁller plug hole, you’ll need to add some lubricant. Add enough lubricant to raise the level to the bottom of the ﬁller plug hole. What to Use Refer to the Maintenance Schedule to determine what kind of lubricant to use. See Part D: Recommended Fluids and Lubricants on page 6-33. 5-48 How to Check Lubricant Four-Wheel Drive Lubricant checks in this section also apply to these vehicles. However, there are two additional systems that need lubrication. Transfer Case When to Check Lubricant Refer to the Maintenance Schedule to determine how often to check the lubricant. See Part C: Periodic Maintenance Inspections on page 6-31. To get an accurate reading, the vehicle should be on a level surface. If the level is below the bottom of the ﬁller plug hole, you’ll need to add some lubricant. Add enough lubricant to raise the level to the bottom of the ﬁller plug hole. Use care not to overtighten the plug. What to Use Refer to the Maintenance Schedule to determine what kind of lubricant to use. See Part D: Recommended Fluids and Lubricants on page 6-33. 5-49 Front Axle When to Check and Change Lubricant Refer to the Maintenance Schedule to determine how often to check the lubricant and when to change it. See Part A: Scheduled Maintenance Services on page 6-4. How to Check Lubricant To get an accurate reading, the vehicle should be on a level surface. If the level is below the bottom of the ﬁller plug hole, you may need to add some lubricant. When the differential is cold, add enough lubricant to raise the level to 1/2 inch (12 mm) below the ﬁller plug hole. When the differential is at operating temperature (warm), add enough lubricant to raise the level to the bottom of the ﬁller plug hole. What to Use Refer to the Maintenance Schedule to determine what kind of lubricant to use.

If you ever have questions about your tire warranty and where to obtain service, see your GM Warranty booklet for details. For additional information refer to the tire manufacturer’s booklet included with your vehicle’s Owner’s Manual. {CAUTION: Poorly maintained and improperly used tires are dangerous. (cid:127) Overloading your tires can cause overheating as a result of too much friction. You could have an air-out and a serious accident. See “Loading Your Vehicle” in the Index. (cid:127) Underinﬂated tires pose the same danger as overloaded tires. The resulting accident could cause serious injury. Check all tires frequently to maintain the recommended pressure. Tire pressure should be checked when your tires are cold. (cid:127) Overinﬂated tires are more likely to be cut, punctured or broken by a sudden impact — such as when you hit a pothole. Keep tires at the recommended pressure. (cid:127) Worn, old tires can cause accidents. If your tread is badly worn, or if your tires have been damaged, replace them. 5-59 Tire Sidewall Labeling Useful information about a tire is molded into its sidewall.

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 5-74. 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 4-54. 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: 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 4-54. 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 4-54, for the location of your vehicle’s tire and loading information label. 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 5-69 (cid:127) (cid:127) (cid:127) 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. 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 5-72 and Wheel Replacement on page 5-76 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 5-79. 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, for scheduled rotation intervals. 5-70 When rotating your tires, always use the correct rotation pattern 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. After the tires have been rotated, adjust the front and rear inﬂation pressures as shown on the Certiﬁcation/Tire label or the Tire and Loading Information label. Make certain that all wheel nuts are properly tightened. See “Wheel Nut Torque” under Capacities and Speciﬁcations on page 5-108. {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. 5-71 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. 5-72 (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 Tire and Loading Information label. 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. 5-73 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. 5-74 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. 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. 5-75 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 5-79 for more information. 5-76 Used Replacement Wheels Tire Chains {CAUTION: {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. Don’t use tire chains. There’s 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 vehicle, drive slowly, readjust or remove the device if it’s contacting your vehicle, and don’t spin your wheels. If you do ﬁnd traction devices that will ﬁt, install them on the rear tires. 5-77 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. 5-78 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 cause an injury. The vehicle can slip off the jack and roll over you or other people. You and they could be badly injured. 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. To be even more certain the vehicle won’t move, you can 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 of the vehicle, at the opposite end. The following steps will tell you how to use the jack and change a tire. 5-79 Removing the Spare Tire and Tools The jacking equipment you’ll need is stored along the driver’s side inner rear quarter panel. In some cases, you may have to remove the spare tire in order to reach the jack. Your vehicle is also equipped with work gloves and a plastic ground mat to assist in the changing of a ﬂat tire. The following instructions explain how to remove the spare tire, depending on where it is mounted on your vehicle. See Compact Spare Tire on page 5-92 or Spare Tire on page 5-92 for more information about the spare. 5-80 A. Retainer B. Rubber Band (Some Models) C. Jack Storage Cover D. Wheel Blocks E. Hub Cap Removal Tools (Some Models) F. Wheel Wrench G. Jack H. Jacking Instructions (Roll and place instructions above the jack after it is installed) 1. To remove your jack cover, pull up on the latch(es) on the cover (C). Remove the wheel blocks (D), jack (G) and wheel wrench (F). If you remove or restow a tire from/to the Notice: 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. To remove the underbody-mounted spare, insert the chisel end of the wheel wrench, on an angle, into the hoist shaft hole in the rear bumper. Be sure the chisel end of the wheel wrench connects into the hoist shaft. 3. Turn the wheel wrench counterclockwise to lower the spare tire. Keep turning the wheel wrench until the spare tire has been completely lowered. Tilt the retainer at the end of the cable and pull it through the wheel opening. Pull the tire out from under the vehicle. If you drive away before the spare tire or Notice: secondary latch system cable has been reinstalled, you could damage your vehicle. Always reinstall this cable before driving your vehicle. If you have an inside-mounted spare tire, the tire must be removed in order to have access to the jack storage. To remove an inside-mounted spare tire, reach into your tire’s cover and unscrew the wing nut at the center of the wheel. Remove it and the retainer. Unhook the tire from the mounting bracket and remove the cover. To remove a rear-mounted spare tire, ﬁrst make sure that the carrier arm is fully-latched to the tailgate. Then remove the spare tire cover. If you have this feature, the locking wheel nut can be removed by snapping the rubber weather cover off the face of the lock case. 5-81 Insert the key and pull the lock case straight off. It is not necessary to turn the key. Put the spare tire near the ﬂat tire. The tools you’ll be using include the jack (A) and wheel wrench (B). Your vehicle may also have an optional hub cap removal tool. 5-82 Removing the Wheel Cover Position the chisel end of your wheel wrench, or the hub cap removal tool (if equipped), in the notch of the hub cap and pry off the hub cap. Some of the molded plastic hub caps have imitation wheel nuts molded into them. The wheel wrench won’t ﬁt these imitation nuts, so don’t try to remove them with the socket end of the wheel wrench. If you have individual wheel nut caps that cover each nut, they must be removed in order to get to the wheel nuts. Use the socket end of the wheel wrench to remove the wheel nut caps. Your wheel nut caps may attach your hub cap to the wheel. Remove these wheel nut caps before you take off the hub cap. 5-83 Removing the Flat Tire and Installing the Spare Tire A. Front Frame Hole B. Rear Frame Hole (2–Door) or Spring Hanger Hole (4–Door) 1. Using the wheel wrench, loosen all the wheel nuts. Don’t remove them yet. 2. Turn the jack handle clockwise to raise the jack lift head. 3. Fit the jack into the appropriate hole nearest the ﬂat tire. 5-84 {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. Raise the vehicle by turning the jack handle clockwise. Raise the vehicle far enough off the ground so there is enough room for the spare tire to ﬁt underneath the wheel well. 5. Remove all the wheel nuts and take off the ﬂat tire. 5-85 6. 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. 7. Place the spare on the wheel mounting surface. 8. Put the nuts on by hand. Make sure the rounded end is toward the wheel. Tighten each nut by hand until the wheel is held against the hub. If a nut can’t be turned by hand, use the wheel wrench and see your dealer as soon as possible. {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. 5-86 {CAUTION: Incorrect wheel nuts or improperly tightened wheel nuts can cause the wheel to become 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 100 lb-ft (140 Y). 9. Lower the vehicle by turning the jack handle counterclockwise. Lower the jack completely. 10. Use the wrench to tighten the wheel nuts ﬁrmly in a crisscross sequence as shown. 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. 5-87 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. Notice: An aluminum wheel with a ﬂat tire should always be stored under the vehicle with the hoist. However, storing it that way for an extended period could damage the wheel. To avoid this, have the wheel repaired as soon as possible. 5-88 Follow this diagram to store the underbody-mounted spare. A. Retainer B. Valve Stem (Pointed Down) C. Spare or Flat Tire D. Spring E. Wheel Wrench F. Lower G. Raise H. Hoist Arm 1. Put the tire on the ground at the rear of the vehicle, with the valve stem pointed down and to the rear. 2. Pull the retainer through the wheel. 3. Put the chisel end of the wheel wrench, on an angle, through the hole in the rear bumper and into the hoist shaft. 4. Raise the tire fully against the underside of the vehicle by turning the wrench clockwise 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, pull, and then try to rotate or turn the tire. If the tire moves, use the wheel wrench to tighten the cable. Follow this diagram for the inside-mounted spare. 5-89 Follow this diagram for the rear-mounted spare. A. Wheel Carrier B. Spare or Flat Tire C. Wheel Nut and Locking Nut Cylinder (If Equipped) 6. Reinstall the locking wheel nut using the wheel wrench. Then push the lock case onto the lug nut until it stops. The key does not have to be inserted into the lock. Push the lock case to be sure it is secured. The special lug nut and lock case is not intended to be used on any road wheel, only on the spare wheel carrier. Tighten the nuts on the wheel carrier to 22 to 32 lb-ft (30 to 40 N·m). A. Spare or Flat Tire B. Retainer C. Nut D. Wheel Carrier E.

Jacking Instructions (roll and place instructions above the jack after it is installed) 5-91 Compact Spare Tire The compact spare tire is a temporary replacement tire made to perform at speeds up to 65 mph (105 km/h) and for distances up to 3,000 miles (5 000 km). With the compact spare installed, you can ﬁnish your trip and then have the damaged or ﬂat road tire repaired or replaced. Of course, it’s best to repair or replace the damaged road tire as soon as you can. Your compact spare tire will last longer and be in good shape in case you need it again. The compact spare may lose air after a time, so check the inﬂation pressure regularly. After installing the compact spare on your vehicle, stop as soon as possible and make sure it’s correctly inﬂated. It should be 60 psi (420 kPa). Don’t use your compact spare tire on other vehicles and don’t mix your compact spare tire or wheel with other wheels or tires, they won’t ﬁt. Keep your compact spare and its wheel together. Don’t include the compact spare in your tire rotation. 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. Spare Tire Your vehicle, when new, had a fully inﬂated spare tire. 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 5-69 and Loading Your Vehicle on page 4-54 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 5-79. 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. If your vehicle has the Xtreme™ Sport Appearance Package (RPO V4A), the spare tire is smaller than your vehicle’s original road tires, so don’t include the spare in the tire rotation. 5-92 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. 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 5-100. 5-93 (cid:127) (cid:127) (cid:127) 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. 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. 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. 5-94 (cid:127) (cid:127) (cid:127) Cleaning Wood Panels Use a clean cloth moistened in warm, soapy water (use mild dish washing soap). Dry the wood immediately with a clean cloth. 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 5-100. 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 Part D: Recommended Fluids and Lubricants on page 6-33. 5-95 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. Don’t wash your vehicle in the direct rays of the sun. Use a car washing soap. Don’t 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 5-100. Don’t 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 5-100. If your vehicle has a “basecoat/clearcoat” paint ﬁnish. The clearcoat gives more depth and gloss to the colored basecoat. Always use waxes and polishes that are non-abrasive and made for a basecoat/clearcoat paint ﬁnish. Notice: Machine compounding or aggressive polishing on a basecoat/clearcoat paint ﬁnish may damage it. Use only non-abrasive waxes and polishes that are made for a basecoat/clearcoat paint ﬁnish on your vehicle. 5-96 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, Backglass and Wiper Blades If the windshield is not clear after using the windshield washer, or if the wiper blade chatters when running, wax, sap or other material may be on the blade or windshield. Clean the outside of the windshield with a full-strength glass cleaning liquid. The windshield is clean if beads do not form when you rinse it with water. Grime from the windshield will stick to the wiper blades and affect their performance. Clean the blade by wiping vigorously with a cloth soaked in full-strength windshield washer solvent. Then rinse the blade with water. Check the wiper blades and clean them as necessary; replace blades that look worn. 5-97 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. Don’t 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. Don’t 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. 5-98 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. 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. 5-99 Vehicle Care/Appearance Materials See your GM dealer for more information on purchasing the following products.

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’ll ﬁnd this label on the inside of the glove box. It’s very helpful if you ever need to order parts. On this label is: your VIN, the model designation, paint information and a list of all production options and special equipment. Be sure that this label is not removed from the vehicle. 5-101 (cid:127) (cid:127) (cid:127) (cid:127) 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. 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 1-57. Headlamps The headlamp wiring is protected by an internal circuit breaker. An electrical overload will cause the lamps to go on and off, or in some cases to remain off. If this happens, have your headlamp wiring checked right away. 5-102 Fuses and Circuit Breakers The wiring circuits in your vehicle are protected from short circuits by a combination of fuses and circuit breakers. This greatly reduces the chance of ﬁres caused by electrical problems. Look at the silver-colored band inside the fuse. If the band is broken or melted, replace the fuse. Be sure you replace a bad fuse with a new one of the identical size and rating. If you ever have a problem on the road and don’t have a spare fuse, you can borrow one that has the same amperage. Just pick some feature of your vehicle that you can get along without — like the radio or cigarette lighter — and use its fuse, if it is the correct amperage. Replace it as soon as you can. Instrument Panel Fuse Block The instrument panel fuse block is located at the end of the instrument panel on the driver’s side of the vehicle. Remove the cover by turning the fastener counterclockwise. Extra fuses and the fuse extractor are provided in the cover.
