Vehicle Maximum Load on the Tire: Load on an individual tire due to curb weight, accessory weight, occupant weight, and cargo weight. Vehicle Placard: A label permanently attached to a vehicle showing the vehicle’s capacity weight and the original equipment tire size and recommended inﬂation pressure. See “Tire and Loading Information Label” under Loading Your Vehicle on page 4-29. 5-58 Inﬂation - Tire Pressure Tires need the correct amount of air pressure to operate effectively. Notice: Do not let anyone tell you that under-inﬂation or over-inﬂation is all right. It is not. If your tires do not have enough air (under-inﬂation), you can get the following: Too much ﬂexing Too much heat Tire overloading (cid:127) Premature or irregular wear (cid:127) Poor handling (cid:127) Reduced fuel economy If your tires have too much air (over-inﬂation), you can get the following: (cid:127) Unusual wear (cid:127) Poor handling (cid:127) Rough ride (cid:127) Needless damage from road hazards (cid:127) (cid:127) (cid:127) A Tire and Loading Information label is attached to the vehicle’s center pillar (B-pillar), below the driver’s door latch. This label shows your vehicle’s original equipment tires and the correct inﬂation pressures for your tires when they are cold. The recommended cold tire inﬂation pressure, shown on the label, is the minimum amount of air pressure needed to support your vehicle’s maximum load carrying capacity. For additional information regarding how much weight your vehicle can carry, and an example of the tire and loading information label, see Loading Your Vehicle on page 4-29. How you load your vehicle affects vehicle handling and ride comfort, never load your vehicle with more weight than it was designed to carry. When to Check Check your tires once a month or more. Also, check the tire pressure of the spare tire. How to Check Use a good quality pocket-type gage to check tire pressure. You cannot tell if your tires are properly inﬂated simply by looking at them. Radial tires may look properly inﬂated even when they’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. Dual Tire Operation When the vehicle is new, or whenever a wheel, wheel bolt or wheel nut is replaced, check the wheel nut torque after 100, 1,000 and 6,000 miles (160, 1 600 and 10 000 km) of driving. For proper wheel nut tightening information, see “Removing the Flat Tire and Installing the Spare Tire” later in this section, under Changing a Flat Tire on page 5-68. Also see “Wheel Nut Torque” under Capacities and Speciﬁcations on page 5-97. 5-59 The outer tire on a dual wheel setup generally wears faster than the inner tire. Your tires will wear more evenly and last longer if you rotate the tires periodically. See Tire Inspection and Rotation on page 5-60. Also see Scheduled Maintenance on page 6-4. {CAUTION: If you operate your vehicle with a tire that is badly underinﬂated, the tire can overheat. An overheated tire can lose air suddenly or catch ﬁre. You or others could be injured. Be sure all tires (including the spare) are properly inﬂated. See Tires on page 5-52 and Inﬂation - Tire Pressure on page 5-58 for more information on proper tire inﬂation. 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 5-62 and Wheel Replacement on page 5-65 for more information. 5-60 Make sure the spare tire is stored securely. Push, pull, and then try to rotate or turn the tire. If it moves, use the ratchet/wheel wrench to tighten the cable. See Changing a Flat Tire on page 5-68. If your vehicle has dual rear wheels, also see Dual Tire Operation on page 5-59. 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. Single Rear Wheels If your vehicle has single rear wheels, always use the correct rotation pattern shown here when rotating your vehicle’s tires. Do not include the spare tire in the tire rotation. Dual Rear Wheels If your vehicle has dual rear wheels, always use one of the correct rotation patterns shown here when rotating your tires. When you install dual wheels, be sure that vent holes in the inner and outer wheels on each side are lined up. After the tires have been rotated, adjust the front and rear inﬂation pressures as shown on the Tire and Loading Information label. See Loading Your Vehicle on page 4-29. Make certain that all wheel nuts are properly tightened. See “Wheel Nut Torque” under Capacities and Speciﬁcations on page 5-97. {CAUTION: Rust or dirt on a wheel, or on the parts to which it is fastened, can make wheel nuts become loose after a time. The wheel could come off and cause an accident. When you change a wheel, remove any rust or dirt from places where the wheel attaches to the vehicle. In an emergency, you can use a cloth or a paper towel to do this; but be sure to use a scraper or wire brush later, if you need to, to get all the rust or dirt off. See Changing a Flat Tire on page 5-68. 5-61 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. For examples of these labels and their location on your vehicle, see Loading Your Vehicle on page 4-29. 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, General Motors 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, load range, 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 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. 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. 5-62 (cid:127) (cid:127) (cid:127) {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. {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. 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. 5-63 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. 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 5-64 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. 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. 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. Whenever a wheel, wheel bolt or wheel nut is replaced on a dual wheel setup, check the wheel nut torque after 100, 1,000 and 6,000 miles (160, 1 600 and 10 000 km) of driving. For proper torque, see “Wheel Nut Torque” under Capacities and Speciﬁcations on page 5-97. See Changing a Flat Tire on page 5-68 for more information. 5-65 CAUTION: (Continued) 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. Used Replacement Wheels {CAUTION: Putting a used wheel on your vehicle is dangerous. You can’t know how it’s been used or how far it’s been driven. It could fail suddenly and cause a crash. If you have to replace a wheel, use a new GM original equipment wheel. Tire Chains {CAUTION: If your vehicle has dual wheels or P235/75R16 or LT245/75R16 size tires, do not use tire chains. They can damage your vehicle because there’s not enough clearance. Tire chains used (Continued) CAUTION: 5-66 If your vehicle does not have dual wheels Notice: and is equipped with a tire size other than P235/75R16 or LT245/75R16, 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. 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. 5-67 CAUTION: (Continued) To be even more certain the vehicle will not move, you should put blocks at the front and rear of the tire farthest away from the one being changed. That would be the tire, on the other side, at the opposite end of the vehicle. When you have a ﬂat tire, use the following example as a guide to assist you in the placement of wheel blocks. Changing a Flat Tire If a tire goes ﬂat, avoid further tire and wheel damage by driving slowly to a level place. Turn on your hazard warning ﬂashers. {CAUTION: Changing a tire can be dangerous. The vehicle can slip off the jack and roll over or fall on you or other people. You and they could be badly injured or even killed. Find a level place to change your tire. To help prevent the vehicle from moving: 1. Set the parking brake ﬁrmly. 2. Put the shift lever in PARK (P). 3. Turn off the engine and do not restart while the vehicle is raised. 4. Do not allow passengers to remain in the vehicle. CAUTION: (Continued) 5-68 The following information will tell you next how to use the jack and change a tire. Removing the Spare Tire and Tools If you have a cargo van or a passenger van, the equipment you will need is located in the passenger side rear corner of the vehicle. Remove the retaining wing bolt and lift it off the mounting bracket. If you have a van with the 15-passenger seating arrangement, the equipment you will need is secured on the rear ﬂoor of the passenger side of the vehicle. To access the equipment, remove the retaining wing bolt and lift it out of the mounting bracket. 5-69 To lower the spare tire from the vehicle, do the following: 1. Attach the wheel wrench and ratchet, with the DOWN side facing you. The wheel wrench has a socket end and a ﬂat chisel end. Note that there is an UP side and a DOWN side on the ratchet. The tools you will be using include the jack (A), jack handle extension (B), jack handle (C), wheel wrench (D) and the ratchet (E). Your spare tire is stored underneath the rear of your vehicle. You will use the wheel wrench (D) and the ratchet (E) to lower the spare tire from the vehicle. 2. Put the ﬂat chisel end of the wheel wrench on an angle through the hole between the body and the bumper. Be sure the ﬂat end connects into the hoist shaft. 5-70 3. Turn the ratchet counterclockwise to lower the spare tire to the ground. 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 on page 5-77. 4. When the tire has been lowered, pull the tire toward you so you can reach the tire retainer and pull it up through the wheel opening. If you have a vehicle which was completed from a cab and chassis, refer to the information from the body supplier/installer. The spare tire is a full-size tire, like the other tires on your vehicle. 5-71 Rear Position Rear Flat: Assemble the jack (A) together with the jack handle (B), jack handle extension (C) and ratchet (D) as shown. Be sure that the ratchet has the UP mark facing you. To assemble the jack handle and jack handle extension, use the art and text following. Removing the Flat Tire and Installing the Spare Tire If your vehicle has plastic wheel nut caps, loosen them by turning the wheel wrench counterclockwise. The wheel nut caps are designed to remain with the center cap. Remove the center cap. If the wheel has a smooth center piece, place the chisel end of the wheel wrench in the slot on the wheel and gently pry it out. 1. With the DOWN side facing you, use the ratchet and wheel wrench to loosen all the wheel nuts. Do not remove them yet. 2. Assemble the jack and tools for a front or rear ﬂat as follows: Front Position Front Flat: Assemble the jack (A) together with the jack handle (B) and ratchet (C) as shown. Be sure that the ratchet has the UP mark facing you. 5-72 Connect the jack handle (B) and jack handle extension (C) together and press the retention clip (arrow) so it engages. Front Position 5-73 3. Position the jack under the vehicle as shown. {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. Rear Position {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. 5-74 4. Raise the vehicle by turning the ratchet clockwise. Make sure the UP mark faces you. Raise the vehicle far enough off the ground so there is enough room for the spare tire to ﬁt. 5. Remove all the wheel nuts, and take off the ﬂat tire. 5-75 {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. 6. Remove any rust or dirt from the wheel bolts, mounting surfaces and spare wheel. 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. Put the wheel nuts back on with the rounded end of the nuts toward the wheel. Tighten each wheel nut by hand until the wheel is held against the hub. 8. Lower the vehicle by turning the jack handle counterclockwise. Lower the jack completely. 5-76 {CAUTION: Incorrect wheel nuts or improperly tightened wheel nuts can cause the wheel to come loose and even come off. This could lead to an accident. Be sure to use the correct wheel nuts. If you have to replace them, be sure to get new GM original equipment wheel nuts. Stop somewhere as soon as you can and have the nuts tightened with a torque wrench to the proper torque speciﬁcation. See Capacities and Speciﬁcations on page 5-97 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 on page 5-97 for the wheel nut torque speciﬁcation. 9. Tighten the nuts ﬁrmly in a crisscross sequence as shown. Turn the wheel wrench clockwise. 10. Put the wheel cover or the center cap and plastic wheel nut caps back on. Remove any wheel blocks. 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 the vehicle if the cable holding the spare tire is damaged. For the secondary latch to work, the tire must be stowed with the valve stem pointing down. 5-77 See Storing a Flat or Spare Tire and Tools on page 5-80 for instructions on storing the spare tire correctly. {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. To release the spare tire from the secondary latch, do the following: {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. 5-78 1. Check under the vehicle to see if the cable end is visible. If the cable is not visible, start this procedure at Step 6. 2. Turn the wrench counterclockwise until approximately 6 inches (15 cm) of cable is exposed. 3. Connect the jack handle (C) and jack handle extension (B) together and press the retention clip (arrow) so it engages. 4. Attach the jack handle/jack handle extension to the jack. With the UP mark facing you, slide the ratchet onto the end of the jack handle extension. The set-up should look like the picture above. 5. Place the jack under the vehicle, ahead of the rear bumper. Position the center lift point of the jack under the center of the spare tire and turn the handle clockwise to raise the jack until it lifts the secondary latch spring. 6. Keep raising the jack until the spare tire stops moving upward and is held ﬁrmly in place. This lets you know that the secondary latch has released. The spare tire is now balancing on the jack. 7. Lower the jack by turning the ratchet counterclockwise. Keep lowering the jack until the spare tire slides off the jack or is hanging by the cable. 5-79 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. 1. Put the tire on the ground at the rear of the vehicle with the valve stem pointed down. 8. 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, slide the ratchet onto the wheel wrench and insert the wheel wrench into the hoist shaft hole above the bumper. Turn the wheel wrench counterclockwise to lower the spare the rest of the way. Be sure the DOWN mark on the ratchet is facing you. 9. 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. 10. If the cable is hanging under the vehicle, turn the wheel wrench in the hoist shaft hole in the bumper 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 repaired or replaced. To continue changing the ﬂat tire, return to Step 4 of Removing the Flat Tire and Installing the Spare Tire on page 5-72. 5-80 2. Pull the retaining bar through the center of the wheel, making sure it is properly attached. 3. Pull the wheel toward the rear of the vehicle, keeping the cable tight. 4. With the UP side facing you, attach the ratchet to the wheel wrench. 5. Put the ﬂat end of the wheel wrench on an angle through the hole in the rear door frame, above the bumper. 5-81 6. Raise the tire fully against the underside of the vehicle. Continue turning the ratchet until the tire is secure and the cable is tight. The spare tire hoist cannot be overtightened. 7. Make sure the tire is stored securely. Push, pull, and then try to rotate or turn the tire. If the tire moves, use the ratchet to tighten the cable. You will hear two clicks when the tire is up all the way. Return the jacking equipment to the proper location. Secure the items and replace the jack cover. Spare Tire Your vehicle, when new, had a fully inﬂated spare tire. A spare tire may lose air over time, so check its inﬂation pressure regularly. See Inﬂation - Tire Pressure on page 5-58 and Loading Your Vehicle on page 4-29 for information regarding proper tire inﬂation and loading your vehicle. For instructions on how to remove, install or store a spare tire, see Removing the Flat Tire and Installing the Spare Tire on page 5-72 and Storing a Flat or Spare Tire and Tools on page 5-80. 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. Your vehicle may have a different size spare tire than the road tires — those originally installed on your vehicle. This spare tire was developed for use on your vehicle, so it’s all right to drive on it. If your vehicle has a spare tire that does not match your vehicle’s original road tires and wheels in size and type, do not include the spare in the tire rotation. Appearance Care Cleaning products can be hazardous. Some are toxic. Other cleaning products can burst into ﬂames if a match is struck near them or if they get on a hot part of the vehicle. Some are dangerous if their fumes are inhaled in an enclosed space. When anything from a container is used to clean the vehicle, be sure to follow the manufacturer’s warnings and instructions. Always open the doors or windows of the vehicle when cleaning the inside. 5-82 Never use these to clean the vehicle: (cid:127) Gasoline (cid:127) Benzene (cid:127) Naphtha (cid:127) Carbon Tetrachloride (cid:127) Acetone (cid:127) Paint Thinner Turpentine Lacquer Thinner (cid:127) Nail Polish Remover They can all be hazardous — some more than others — and they can all damage the vehicle, too. Do not use any of these products unless this manual says you can. In many uses, these will damage the vehicle: (cid:127) Alcohol Laundry Soap (cid:127) Bleach (cid:127) Reducing Agents Fabric/Carpet Use a vacuum cleaner often to get rid of dust and loose dirt. Wipe vinyl, leather, plastic, and painted surfaces with a clean, damp cloth. GM-approved cleaning products can be obtained from your dealer. Here are some cleaning tips: (cid:127) Always read the instructions on the cleaner label. (cid:127) Clean up stains as soon as you can before they set. (cid:127) Carefully scrape off any excess stain. (cid:127) Use a clean cloth or sponge, and change to a clean area often. A soft brush may be used if stains are stubborn. To avoid forming a ring on fabric after spot cleaning, clean the entire area immediately or it will set. Most stains can be removed with club soda water. To clean, use the following instructions: 1. For liquids: blot with a clean, soft, white cloth. For solids: remove as much as possible and then vacuum or brush. 2. Apply club soda water to a clean, soft, white cloth. Do not over-saturate; the cloth should not drip water. 5-83 (cid:127) (cid:127) (cid:127) (cid:127) 3. Clean the entire area. Avoid getting the fabric too wet. 4. Start cleaning from the seams into the stain to avoid a ring effect. 5. Continue cleaning, using a clean area of the cloth each time it becomes soiled. 6. When the stain is removed, blot the cleaned area with another dry, clean, soft, white cloth. Using Cleaner on Fabric 1. First, try the cleaner on an area of the fabric that is not easily seen to make sure the cleaner does not affect the color of the fabric. 2. For liquids: blot with a clean, soft, white cloth. For solids: remove as much as possible and then vacuum or brush. 3. Spray a small amount of the cleaner onto a clean soft, white, cloth. Do not apply spray directly to the fabric. 4. Start cleaning from the seams into the stain to avoid a ring effect. 5. Continue cleaning, using a clean area of the cloth each time it becomes soiled. 6. When the stain is removed, blot the cleaned area with another dry, clean, soft, white cloth. 7. If the cleaner leaves a ring effect, follow up with the club soda water instructions given earlier in this section. Special Fabric Cleaning Problems Stains caused by such things as catsup, black coffee, egg, fruit, fruit juice, milk, soft drinks, vomit, urine, and blood can be removed using the club soda water instructions given earlier in this section. If an odor lingers after cleaning vomit or urine, treat the area with a water and baking soda solution: 1 teaspoon (5 ml) of baking soda to 1 cup (250 ml) of lukewarm water. Let dry. Stains caused by oil and grease can be cleaned with an approved GM cleaner and a clean, white cloth. 1. Carefully scrape off excess stain. 2. Clean with cool water and allow to dry completely. 3. If a stain remains, follow the “Using Cleaner on Fabric” instructions described earlier. 5-84 Vinyl Use warm water and a clean cloth. (cid:127) Rub with a clean, damp cloth to remove dirt. This may have to be done more than once. Things like tar, asphalt, and shoe polish will stain if they are not removed quickly. Use a clean cloth and vinyl cleaner. See your dealer for this product. 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. Interior Plastic Components Use only a mild soap and water solution on a soft cloth or sponge. Commercial cleaners may affect the surface ﬁnish. 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 5-90. 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. 5-85 (cid:127) Weatherstrips Silicone grease on weatherstrips will make them last longer, seal better, and not stick or squeak. Apply silicone grease with a clean cloth. During very cold, damp weather frequent application may be required. See Recommended Fluids and Lubricants on page 6-13. Washing Your Vehicle The paint ﬁnish on the vehicle provides beauty, depth of color, gloss retention, and durability. The best way to preserve the vehicle’s ﬁnish is to keep it clean by washing it often with lukewarm or cold water. Do not wash the vehicle in the direct rays of the sun. Use a car washing soap. Do not use strong soaps or chemical detergents. Be sure to rinse the vehicle well, removing all soap residue completely. GM-approved cleaning products can be obtained from your dealer. See Vehicle Care/Appearance Materials on page 5-90. 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 the vehicle. 5-86 Cleaning Exterior Lamps/Lenses Use only lukewarm or cold water, a soft cloth and a car washing soap to clean exterior lamps and lenses. Follow instructions under Washing Your Vehicle on page 5-86. 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 5-90. If your vehicle has a “basecoat/clearcoat” paint ﬁnish. The clearcoat gives more depth and gloss to the colored basecoat. Always use waxes and polishes that are non-abrasive and made for a basecoat/clearcoat paint ﬁnish. Notice: Machine compounding or aggressive polishing on a basecoat/clearcoat paint ﬁnish may damage it. Use only non-abrasive waxes and polishes that are made for a basecoat/clearcoat paint ﬁnish on your vehicle. Foreign materials such as calcium chloride and other salts, ice melting agents, road oil and tar, tree sap, bird droppings, chemicals from industrial chimneys, etc., can damage your vehicle’s ﬁnish if they remain on painted surfaces. Wash the vehicle as soon as possible. If necessary, use non-abrasive cleaners that are marked safe for painted surfaces to remove foreign matter. Exterior painted surfaces are subject to aging, weather and chemical fallout that can take their toll over a period of years. You can help to keep the paint ﬁnish looking new by keeping your vehicle garaged or covered whenever possible. Protecting Exterior Bright Metal Parts Bright metal parts should be cleaned regularly to keep their luster. Washing with water is all that is usually needed. However, you may use chrome polish on chrome or stainless steel trim, if necessary. Use special care with aluminum trim. To avoid damaging protective trim, never use auto or chrome polish, steam or caustic soap to clean aluminum. A coating of wax, rubbed to high polish, is recommended for all bright metal parts. Windshield and Wiper Blades If the windshield is not clear after using the windshield washer, or if the wiper blade chatters when running, wax, sap, or other material may be on the blade or windshield. Clean the outside of the windshield with a glass cleaning liquid or powder and water solution. The windshield is clean if beads do not form when it is rinsed with water. Grime from the windshield will stick to the wiper blades and affect their performance. Clean the blade by wiping vigorously with a cloth soaked in full-strength windshield washer solvent. Then rinse the blade with water. Check the wiper blades and clean them as necessary; replace blades that look worn. 5-87 If you use strong soaps, chemicals, Aluminum Wheels Notice: abrasive polishes, cleaners, brushes, or cleaners that contain acid on aluminum or chrome-plated wheels, you could damage the surface of the wheel(s). The repairs would not be covered by your warranty. Use only GM-approved cleaners on aluminum or chrome-plated wheels. Keep the wheels clean using a soft clean cloth with mild soap and water. Rinse with clean water. After rinsing thoroughly, dry with a soft clean towel. A wax may then be applied. Notice: Using chrome polish on aluminum wheels could damage the wheels. The repairs would not be covered by your warranty. Use chrome polish on chrome wheels only. The surface of these wheels is similar to the painted surface of the vehicle. Do not use strong soaps, chemicals, abrasive polishes, abrasive cleaners, cleaners with acid, or abrasive cleaning brushes on them because the surface could be damaged. Do not use chrome polish on aluminum wheels. If you drive your vehicle through an Notice: automatic car wash that has silicone carbide tire cleaning brushes, you could damage the aluminum or chrome-plated wheels. The repairs would not be covered by your warranty. Never drive a vehicle equipped with aluminum or chrome-plated wheels through an automatic car wash that uses silicone carbide tire cleaning brushes. Do not take the vehicle through an automatic car wash that has silicone carbide tire cleaning brushes. These brushes can also damage the surface of these wheels. Tires To clean the tires, use a stiff brush with tire cleaner. Notice: Using petroleum-based tire dressing products on your vehicle may damage the paint ﬁnish and/or tires. When applying a tire dressing, always wipe off any overspray from all painted surfaces on your vehicle. 5-88 At least every spring, ﬂush these materials from the underbody with plain water. Clean any areas where mud and debris can collect. Dirt packed in close areas of the frame should be loosened before being ﬂushed. Your GM dealer or an underbody car washing system can do this for you. Chemical Paint Spotting Some weather and atmospheric conditions can create a chemical fallout. Airborne pollutants can fall upon and attack painted surfaces on the vehicle. This damage can take two forms: blotchy, ring-shaped discolorations, and small, irregular dark spots etched into the paint surface. Although no defect in the paint job causes this, GM will repair, at no charge to the owner, the surfaces of new vehicles damaged by this fallout condition within 12 months or 12,000 miles (20 000 km) of purchase, whichever occurs ﬁrst. Sheet Metal Damage If the vehicle is damaged and requires sheet metal repair or replacement, make sure the body repair shop applies anti-corrosion material to parts repaired or replaced to restore corrosion protection. Original manufacturer replacement parts will provide the corrosion protection while maintaining the warranty. Finish Damage Any stone chips, fractures or deep scratches in the ﬁnish should be repaired right away. Bare metal will corrode quickly and may develop into major repair expense. Minor chips and scratches can be repaired with touch-up materials available from your GM dealer. Larger areas of ﬁnish damage can be corrected in your GM dealer’s body and paint shop. Underbody Maintenance Chemicals used for ice and snow removal and dust control can collect on the underbody. If these are not removed, corrosion and rust can develop on the underbody parts such as fuel lines, frame, ﬂoor pan, and exhaust system even though they have corrosion protection. 5-89 Vehicle Care/Appearance Materials See your GM dealer for more information on purchasing the following products.

Odor Eliminator Spot Lifter Vehicle Identiﬁcation Vehicle Identiﬁcation Number (VIN) This is the legal identiﬁer for your vehicle. It appears on a plate in the front corner of the instrument panel, on the driver’s side. You can see it if you look through the windshield from outside your vehicle. The VIN also appears on the Vehicle Certiﬁcation and Service Parts labels and the certiﬁcates of title and registration. Engine Identiﬁcation The eighth character in your VIN is the engine code. This code will help you identify your engine, speciﬁcations and replacement parts. Service Parts Identiﬁcation Label You will ﬁnd this label on the front passenger door frame. It is very helpful if you ever need to order parts. On this label you will ﬁnd the following: (cid:127) VIN (cid:127) Model designation (cid:127) Paint information (cid:127) Production options and special equipment Be sure that this label is not removed from the vehicle. 5-91 Electrical System Add-On Electrical Equipment Notice: Don’t add anything electrical to your vehicle unless you check with your dealer ﬁrst. Some electrical equipment can damage your vehicle and the damage wouldn’t be covered by your warranty. Some add-on electrical equipment can keep other components from working as they should. Your vehicle has an air bag system. Before attempting to add anything electrical to your vehicle, see Servicing Your Airbag-Equipped Vehicle on page 1-69. Headlamp Wiring The headlamp wiring is protected by a circuit breaker in the lamp switch. An electrical overload will cause the lamps to ﬂicker on and off, or in some cases to remain off. If this happens, have your headlamp wiring checked right away. Windshield Wiper Fuses The windshield wiper motor is protected by a circuit breaker and a fuse. If the motor overheats due to heavy snow, etc., the wiper will stop until the motor cools. Although the circuit is protected from electrical overload, overload due to heavy snow, etc., may cause wiper linkage damage. Always clear ice and heavy snow from the windshield before using the windshield wipers. If the overload is caused by some electrical problem and not snow, etc., be sure to get it ﬁxed. 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. 5-92 Floor Console Fuse Block The ﬂoor console fuse block is located under the driver’s seat.

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 4-29. are driven on reasonable road surfaces within legal driving limits. use the recommended fuel. See Gasoline Octane on page 5-5. The services in Scheduled Maintenance on page 6-4 should be performed when indicated. See Additional Required Services on page 6-6 and Maintenance Footnotes on page 6-8 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. When you go to your GM Goodwrench dealer for your service needs, you will know that GM-trained and supported service technicians will perform the work using genuine GM parts. If you want to purchase service information, see Service Publications Ordering Information on page 7-11. 6-3 (cid:127) (cid:127) (cid:127) Owner Checks and Services on page 6-10 tells you what should be checked, when to check it and what you can easily do to help keep your vehicle in good condition. The proper replacement parts, ﬂuids and lubricants to use are listed in Recommended Fluids and Lubricants on page 6-13 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 engine oil light comes on, it means that service is required for your vehicle. Have your vehicle serviced as soon as possible within the next 600 miles (1 000 km). It is possible that, if you are driving under the best conditions, the engine oil life system may not indicate that vehicle service is necessary for over a year. However, your engine oil and ﬁlter must be changed at least once a year and at this time the system must be reset. Your GM Goodwrench dealer has GM-trained service technicians who will perform this work using genuine GM parts and reset the system. 6-4 If the engine oil life system is ever reset accidentally, you must service your vehicle within 3,000 miles (5 000 km) since your last service. Remember to reset the oil life system whenever the oil is changed. See Engine Oil Life System on page 5-16 for information on the Engine Oil Life System and resetting the system. When the change engine oil light appears, certain services, checks and inspections are required. Required services are described in the following for “Maintenance I” and “Maintenance II.” Generally, it is recommended that your ﬁrst service be Maintenance I, your second service be Maintenance II and that you alternate Maintenance I and Maintenance II thereafter. However, in some cases, Maintenance II may be required more often. Maintenance I — Use Maintenance I if the change engine oil light comes on within 10 months since the vehicle was purchased or Maintenance II was performed. Maintenance II — Use Maintenance II if the previous service performed was Maintenance I.
