Each TPMS sensor has a unique identiﬁcation code. Any time you replace one or more of the TPMS sensors, rotate the vehicle’s tires, or install a full-size spare that has a TPMS sensor, the sensor’s identiﬁcation codes will need to be matched to the new tire/wheel position. Each tire/wheel position is matched to the TPMS sensor using a TPMS diagnostic tool. See your GM dealer for service. The TPMS sensors may also be matched to each tire/wheel position by increasing or decreasing the tire’s air pressure. When increasing the tire’s air pressure, do not exceed the maximum tire pressure indicated on the tire’s sidewall. You will have two minutes to match the ﬁrst tire/wheel position, and ﬁve minutes overall, to match all four tire/wheel positions. If it takes longer than two minutes, to match the ﬁrst tire and wheel, or more than ﬁve minutes to match all four tire and wheel positions the matching process stops and you will need to start over. The TPMS matching process is outlined below: 1. Set the parking brake. 2. Turn the ignition switch to RUN with the engine off. 3. Press the Driver Information Center (DIC) vehicle information button until the RELEARN TIRE POSITIONS displays. 4. Press the set/reset button to allow the system to learn the tire positions. The horn will sound twice to indicate that the TPMS is ready, and then the message TIRE LEARNING ACTIVE will display. The sensor matching process can begin. 5. Start with the driver’s side front tire. 6. Remove the valve cap from the valve stem. Activate the TPMS sensor by increasing or decreasing the tire’s air pressure for ﬁve seconds, or until a horn chirp sounds. The horn chirp, which may take up to 30 seconds, conﬁrms that the sensor identiﬁcation code has been matched to this tire position. To decrease the tire’s air-pressure use the pointed end of the valve cap, a pencil-style air pressure gage or a key. 5-61 7. Proceed to the passenger’s side front tire, and repeat the procedure in Step 6. 8. Proceed to the passenger’s side rear tire, and repeat the procedure in Step 6. 9. Proceed to the driver’s side rear tire, and repeat the procedure in Step 6. 10. When the re-learning is complete, the horn will sound and the TIRE LEARNING ACTIVE message will clear from the DIC display. Exit the matching process by turning the ignition switch to OFF. 11. Set all four tires to the recommended air pressure level as indicated on the tire and loading information label. 12. Put the valve caps back on the valve stems. The compact spare tire does not have a TPMS sensor. If you replace one of the road tires with the compact spare, the SERVICE TIRE MONITOR SYSTEM message will be displayed on the DIC screen. This message should go off once you re-install the road tire containing the TPMS sensor. The SERVICE TIRE MONITOR SYSTEM message is also displayed when a part of the TPMS is not working properly. One or more missing or inoperable TPMS sensors will cause the service tire monitor message to be displayed. See your GM dealer for service if all the TPMS sensors are installed and the error message comes on and stays on. This device complies with Part 15 of the FCC Rules.

This device must accept any interference received, including interference that may cause undesired operation of the device. Changes or modiﬁcations to this system by other than an authorized service facility could void authorization to use this equipment. 5-62 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 5-64 and Wheel Replacement on page 5-69 for more information. 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. Four-Tire Rotation Pattern If your vehicle has a compact spare tire, it should not be included in the tire rotation process. Use the four-tire rotation pattern shown. Five-Tire Rotation Pattern A ﬁve-tire rotation pattern may be used for your professional vehicle, if it has a full-size spare tire and wheel assembly that matches the original equipment tires and wheels in size, type and brand. The correct ﬁve-tire rotation pattern is shown. 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 4-31. Vehicles that have the Tire Pressure Monitor System (TPMS) will need to have the sensors reset after a tire rotation is performed. See Tire Pressure Monitor System on page 5-59. 5-63 Make certain that all wheel nuts are properly tightened. See “Wheel Nut Torque” under Capacities and Speciﬁcations on page 5-101. {CAUTION: Rust or dirt on a wheel, or on the parts to which it is fastened, can make wheel nuts become loose after a time. The wheel could come off and cause an accident. When you change a wheel, remove any rust or dirt from places where the wheel attaches to the vehicle. In an emergency, you can use a cloth or a paper towel to do this; but be sure to use a scraper or wire brush later, if needed, to get all the rust or dirt off. See Changing a Flat Tire on page 5-72. 5-64 When It Is Time for New Tires One way to tell when it is 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. 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 cannot be repaired well because of the size or location of the damage. (cid:127) (cid:127) (cid:127) Buying New Tires GM has developed and matched speciﬁc tires for your vehicle. The original equipment tires installed on your vehicle, when it was new, were designed to meet General Motors Tire Performance Criteria Speciﬁcation (TPC spec) system rating. If you need replacement tires, GM strongly recommends that you get tires with the same TPC Spec rating. This way, your vehicle will continue to have tires that are designed to give the same performance and vehicle safety, during normal use, as the original tires. GM’s exclusive TPC Spec system considers over a dozen critical speciﬁcations that impact the overall performance of your vehicle, including brake system performance, ride and handling, traction control, and tire pressure monitoring performance. GM’s TPC Spec number is molded onto the tire’s sidewall by the tire manufacturer. If the tires have an all-season tread design, the TPC spec number will be followed by an MS for mud and snow. See Tire Sidewall Labeling on page 5-50 for additional information. {CAUTION: Mixing tires could cause you to lose control of your vehicle while driving. If you mix tires of different sizes, brands, or types (radial and bias-belted tires), the vehicle may not handle properly, and you could have a crash. Using tires of different sizes, brands, or types may also cause damage to your vehicle. Be sure to use the correct size, brand, and type of tires on all wheels. Your vehicle may have a compact spare tire and wheel assembly. If the vehicle has a compact spare tire and wheel, they have the same overall diameter as your vehicle’s full-size tires and wheels. Because they were designed and developed for use on your vehicle, it is all right to drive your vehicle with the compact spare installed properly. Compact spare tires are designed for temporary use only. See Spare Tire on page 5-81. 5-65 Your vehicle’s original equipment tires are listed on the Tire and Loading Information Label. This label is attached to the vehicle’s center pillar (B-pillar). See Loading Your Vehicle on page 4-31. Different Size Tires and Wheels If you add wheels or tires that are a different size than your original equipment wheels and tires, this may affect the way your vehicle performs, including its braking, ride and handling characteristics, stability and resistance to rollover. Additionally, if your vehicle has electronic systems such as, antilock brakes; traction control; and electronic stability control, the performance of these systems can be affected. {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. If you must replace your vehicle’s tires with those that do not have a TPC Spec number, make sure they are the same size, load range, speed rating, and construction type (radial and bias-belted tires) as your vehicle’s original tires. Vehicles that have a tire pressure monitoring system may give an inaccurate low-pressure warning if non-TPC spec rated tires are installed on your vehicle. Non-TPC Spec rated tires may give a low-pressure warning that is higher or lower than the proper warning level you would get with TPC Spec rated tires. See Tire Pressure Monitor System on page 5-59 5-66 {CAUTION: If you add different sized wheels, your vehicle may not provide an acceptable level of performance and safety if tires not recommended for those wheels are selected. You may increase the chance that you will crash and suffer serious injury. Only use GM speciﬁc wheel and tire systems developed for your vehicle, and have them properly installed by a GM certiﬁed technician. See Buying New Tires on page 5-65 and Accessories and Modiﬁcations on page 5-3 for additional information. 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. 5-67 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 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. 5-68 Wheel Alignment and Tire Balance The tires and wheels on your vehicle were aligned and balanced carefully at the factory to give you the longest tire life and best overall performance. Adjustments to wheel alignment and tire balancing will not be necessary on a regular basis. However, if you notice unusual tire wear or your vehicle pulling to one side or the other, the alignment may need to be checked. If you notice your vehicle vibrating when driving on a smooth road, your tires and wheels may need to be rebalanced. See your dealer for proper diagnosis. 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. Some aluminum wheels can sometimes be repaired. See your GM dealer if any of these conditions exist. Your GM 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. If your vehicle is a professional model, the wheels have a unique offset and bolt hole diameter. Each of the wheels on the professional vehicle have eight wheels nuts. The wheels on the non-professional vehicle have ﬁve wheel nuts. See Changing a Flat Tire on page 5-72 for more information. 5-69 Used Replacement Wheels Tire Chains {CAUTION: {CAUTION: Putting a used wheel on your vehicle is dangerous. You cannot know how it has been used or how far it has been driven. It could fail suddenly and cause a crash. If you have to replace a wheel, use a new GM original equipment wheel. Do not use tire chains. There is not enough clearance. Tire chains used on a vehicle without the proper amount of clearance can cause damage to the brakes, suspension or other vehicle parts. The area damaged by the tire chains could cause you to lose control of your vehicle and you or others may be injured in a crash. Use another type of traction device only if its manufacturer recommends it for use on your vehicle and tire size combination and road conditions. Follow that manufacturer’s instructions. To help avoid damage to your vehicle, drive slowly, readjust or remove the device if it is contacting your vehicle, and do not spin your vehicle’s wheels. If you do ﬁnd traction devices that will ﬁt, install them on the front tires. 5-70 If a Tire Goes Flat It is unusual for a tire to blowout while you are driving, especially if you maintain your vehicle’s tires properly. If air goes out of a tire, it is 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 would 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 the jacking equipment to change a ﬂat tire safely. 5-71 CAUTION: (Continued) 3. Turn off the engine and do not restart while the vehicle is raised. 4. Do not allow passengers to remain in the vehicle. 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. 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 vehicle’s hazard warning ﬂashers. See Hazard Warning Flashers on page 3-6 for more information. {CAUTION: Changing a tire can be dangerous. The vehicle can slip off the jack and roll over or fall on you or other people. You and they could be badly injured or even killed. Find a level place to change your tire. To help prevent the vehicle from moving: 1. Set the parking brake ﬁrmly. 2. Put the shift lever in PARK (P). CAUTION: (Continued) 5-72 When your vehicle has a ﬂat tire, use the following example as a guide to assist you in the placement of wheel blocks. Removing the Spare Tire and Tools The equipment you will need is in the trunk. To access the equipment, do the following: 1. Open the trunk. See Trunk on page 2-13 for more information. 2. Press the area at the front of the handle located on the cover so that the back edge raises. The following information will tell you next how to use the jack and change a tire. 3. Grab the handle and remove the cover. 5-73 4. Turn the wing nut to remove the retainer that holds the wrench and jack. 5. Remove the wheel wrench, jack and spare tire from the trunk. See Spare Tire on page 5-81 for more information. The tools you will be using include the jack (A) and the wheel wrench (B). 5-74 Removing the Flat Tire and Installing the Spare Tire 2. For models with exposed lug nuts, loosen them using the wheel wrench. Do not remove them yet. 1. For models having aluminum wheels with a center wheel cover, use the ﬂat end of the wheel wrench to gently pry the wheel covers off. Be careful not to scratch the aluminum wheel edge and do not try to remove it with your hands. Then loosen the wheel nuts with the wheel wrench. Do not remove them yet. 5-75 {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. If you position the jack under the rocker Notice: molding and attempt to raise the vehicle, you could break the molding and/or cause other damage to your vehicle. Always position the jack so that when the jack head is raised, it will ﬁt ﬁrmly in the notch located inboard from the rocker molding. 3. Find the jacking location from the diagram above and use the corresponding cutouts located in the plastic molding. The front location is (A) 8.5 inches (21 cm) from the rear edge of the front wheel well, and the rear location (B) is 3.5 inches (8.5 cm) from the front edge of the rear wheel well. The notches may also be labeled JACK with an arrow pointing to the jacking location on the vehicle. 5-76 4. Turn the jack handle counterclockwise to lower the jack lift head until the jack ﬁts under the vehicle. 5. Raise the jack until the metal ﬂange ﬁts ﬁrmly into the channel of the jack head. 6. Put the spare tire near you. 7. Raise the vehicle by turning the jack handle clockwise. Raise the vehicle far enough off the ground for the spare tire to ﬁt under the vehicle. 5-77 8. Remove all wheel nuts and take off the ﬂat tire. 10. Place the spare tire on the wheel-mounting surface. {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 needed, to get all the rust or dirt off. 9. 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. 11. Put the wheel nuts back on with the rounded end of the nuts toward the wheel. Tighten each nut by hand until the wheel is held against the hub. 5-78 12. Lower the vehicle by turning the jack handle counterclockwise. Lower the jack completely. {CAUTION: Incorrect wheel nuts or improperly tightened wheel nuts can cause the wheel to come loose and even come off. This could lead to an accident. Be sure to use the correct wheel nuts. If you have to replace them, be sure to get new GM original equipment wheel nuts. Stop somewhere as soon as you can and have the nuts tightened with a torque wrench to the proper torque speciﬁcation. See Capacities and Speciﬁcations on page 5-101 for wheel nut torque speciﬁcation. Improperly tightened wheel nuts can lead Notice: to brake pulsation and rotor damage. To avoid expensive brake repairs, evenly tighten the wheel nuts in the proper sequence and to the proper torque speciﬁcation. See Capacities and Speciﬁcations on page 5-101 for the wheel nut torque speciﬁcation. 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. After you have put the spare tire on your vehicle, you will need to store the ﬂat tire in your trunk. Store the ﬂat tire as far forward in the trunk as possible. Store the jack and wheel wrench in their compartment in the trunk. For storage, the jack must be raised until the screw end is ﬂush with the edge of the jack. The compact spare is for temporary use only. Replace the compact spare tire with a full-size tire as soon as you can. 5-Wheel Nuts 8-Wheel Nuts 13. Tighten the wheel nuts ﬁrmly in a crisscross sequence as shown. If your vehicle is equipped with wheel nut covers, screw the nut covers on with your ﬁngers, then tighten one-quarter turn with the wheel wrench. Notice: Wheel covers will not ﬁt on your compact spare. If you try to put a wheel cover on the compact spare, you could damage the cover or the spare. Do not try to put a wheel cover on your compact spare tire, if equipped. It will not ﬁt. Store the wheel cover and lug nut caps in the trunk until you have the ﬂat tire repaired or replaced. 5-80 3. Insert the jack container (E) into the spare tire (F). Then insert the jack and wheel wrench (D) into the center of the compact spare tire making sure to line up the wheel nut hole with the bolt (G) on the compartment ﬂoor. 4. Secure the tire and wheel with the retainer (C) and then the wing nut (B). 5. Reinstall the compact spare tire cover (A). Spare Tire Compact Spare Tire Your vehicle may be equipped with a compact spare tire. Although the compact spare tire was fully inﬂated when the vehicle was new, it can lose air after a time. Check the inﬂation pressure regularly. It should be 60 psi (420 kPa). 5-81 A. Cover B. Wing Nut C. Retainer D. Jack and Wheel Wrench E. Jack Container F. Spare Tire G. Bolt 1. Open the trunk. See Trunk on page 2-13 2. Reinstall the spare tire (F) with the valve stem up, and line up the wheel nut hole with the bolt (G) or wheel center and place on the compartment ﬂoor. After installing the compact spare on the vehicle, stop as soon as possible and make sure the spare tire is correctly inﬂated. The compact spare is made to perform well at speeds up to 65 mph (105 km/h) for distances up to 3,000 miles (5 000 km), so you can ﬁnish your trip and have the full-size tire repaired or replaced at your convenience. Of course, it is best to replace the spare with a full-size tire as soon as possible. The spare tire will last longer and be in good shape in case it is needed again. Notice: When the compact spare is installed, do not take your vehicle through an automatic car wash with guide rails. The compact spare can get caught on the rails. That can damage the tire and wheel, and maybe other parts of your vehicle. Do not use the compact spare on other vehicles. And do not mix the compact spare tire or wheel with other wheels or tires. They will not ﬁt. Keep the spare tire and its wheel together. Notice: Tire chains will not ﬁt your compact spare. Using them can damage your vehicle and can damage the chains too. Do not use tire chains on your compact spare. Spare Tire Your vehicle may be equipped with a spare tire, which, when new, was fully inﬂated. A spare tire may lose air over time, so check its inﬂation pressure regularly. See Inﬂation - Tire Pressure on page 5-56 and Loading Your Vehicle on page 4-31 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 5-75. 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 tire, that was originally installed on your vehicle. This spare tire was developed for use on your vehicle, so it is 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. 5-82 Appearance Care Cleaning the Inside of Your Vehicle Your vehicle’s interior will continue to look its best if it is cleaned often. Although not always visible, dust and dirt can accumulate on your upholstery. Dirt can damage carpet, fabric, leather, and plastic surfaces. Regular vacuuming is recommended to remove particles from your upholstery. It is important to keep your upholstery from becoming and remaining heavily soiled. Soils should be removed as quickly as possible. Your vehicle’s interior may experience extremes of heat that could cause stains to set rapidly. Lighter colored interiors may require more frequent cleaning. Use care because newspapers and garments that transfer color to your home furnishings may also transfer color to your vehicle’s interior. When cleaning your vehicle’s interior, only use cleaners speciﬁcally designed for the surfaces being cleaned. Permanent damage may result from using cleaners on surfaces for which they were not intended. Use glass cleaner only on glass. Remove any accidental over-spray from other surfaces immediately. To prevent over-spray, apply cleaner directly to the cleaning cloth. If you use abrasive cleaners when cleaning Notice: glass surfaces on your vehicle, you could scratch the glass and/or cause damage to the integrated radio antenna and the rear window defogger. When cleaning the glass on your vehicle, use only a soft cloth and glass cleaner. Many cleaners contain solvents that may become concentrated in your vehicle’s breathing space. Before using cleaners, read and adhere to all safety instructions on the label. While cleaning your vehicle’s interior, maintain adequate ventilation by opening your vehicle’s doors and windows. Dust may be removed from small buttons and knobs using a small brush with soft bristles. Your GM dealer has a product for cleaning your vehicle’s glass. Should it become necessary, you can also obtain a product from your GM dealer to remove odors from your vehicle’s upholstery. 5-83 Do not clean your vehicle using the following cleaners or techniques: (cid:127) Never use a knife or any other sharp object to remove a soil from any interior surface. (cid:127) Never use a stiff brush. It can cause damage to your vehicle’s interior surfaces. (cid:127) Never apply heavy pressure or rub aggressively with a cleaning cloth. Use of heavy pressure can damage your interior and does not improve the effectiveness of soil removal. (cid:127) Use only mild, neutral-pH soaps. Avoid laundry detergents or dishwashing soaps with degreasers. Using too much soap will leave a residue that leaves streaks and attracts dirt. For liquid cleaners, about 20 drops per gallon (3.78 L) of water is a good guide. (cid:127) Do not heavily saturate your upholstery while cleaning. (cid:127) Damage to your vehicle’s interior may result from the use of many organic solvents such as naptha, alcohol, etc. 5-84 Fabric/Carpet Use a vacuum cleaner with a soft brush attachment frequently to remove dust and loose dirt. A canister vacuum with a beater bar in the nozzle may only be used on ﬂoor carpet and carpeted ﬂoor mats. For soils, always try to remove them ﬁrst with plain water or club soda. Before cleaning, gently remove as much of the soil as possible using one of the following techniques: For liquids: gently blot the remaining soil with a paper towel. Allow the soil to absorb into the paper towel until no more can be removed. For solid dry soils: remove as much as possible and then vacuum. To clean, use the following instructions: 1. Saturate a lint-free, clean white cloth with water or club soda. 2. Wring the cloth to remove excess moisture. 3. Start on the outside edge of the soil and gently rub toward the center. Continue cleaning, using a clean area of the cloth each time it becomes soiled. 4. Continue to gently rub the soiled area until the cleaning cloth remains clean. 5. If the soil is not completely removed, use a mild soap solution and repeat the cleaning process that was used with plain water. (cid:127) (cid:127) If any of the soil remains, a commercial fabric cleaner or spot lifter may be necessary. When a commercial upholstery cleaner or spot lifter is to be used, test a small hidden area for colorfastness ﬁrst. If the locally cleaned area gives any impression that a ring formation may result, clean the entire surface. After the cleaning process has been completed, a paper towel can be used to blot excess moisture from the fabric or carpet. Leather A soft cloth dampened with water may be used to remove dust. If a more thorough cleaning is necessary, a soft cloth dampened with a mild soap solution can be used. Allow the leather to dry naturally. Do not use heat to dry. Never use steam to clean leather. Never use spot lifters or spot removers on leather. Many commercial leather cleaners and coatings that are sold to preserve and protect leather may permanently change the appearance and feel of your leather and are not recommended. Do not use silicone or wax-based products, or those containing organic solvents to clean your vehicle’s interior because they can alter the appearance by increasing the gloss in a non-uniform manner. Never use shoe polish on your leather. Instrument Panel, Vinyl, and Other Plastic Surfaces A soft cloth dampened with water may be used to remove dust. If a more thorough cleaning is necessary, a clean soft cloth dampened with a mild soap solution can be used to gently remove dust and dirt. Never use spot lifters or removers on plastic surfaces. Many commercial cleaners and coatings that are sold to preserve and protect soft plastic surfaces may permanently change the appearance and feel of your interior and are not recommended. Do not use silicone or wax-based products, or those containing organic solvents to clean your vehicle’s interior because they can alter the appearance by increasing the gloss in a non-uniform manner. Some commercial products may increase gloss on your instrument panel. The increase in gloss may cause annoying reﬂections in the windshield and even make it difficult to see through the windshield under certain conditions. Wood Panels Use a clean cloth moistened in warm, soapy water (use mild dish washing soap). Dry the wood immediately with a clean cloth. 5-85 Speaker Covers Vacuum around a speaker cover gently, so that the speaker will not be damaged. Clean spots with just water and mild soap. 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. During very cold, damp weather frequent application may be required. See Recommended Fluids and Lubricants on page 6-12. 5-86 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. 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 the vehicle by hand may be necessary to remove residue from the paint ﬁnish. GM-approved cleaning products can be obtained from your dealer. See Vehicle Care/Appearance Materials on page 5-90. 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. The vehicle has a “basecoat/clearcoat” paint ﬁnish. The clearcoat gives more depth and gloss to the colored basecoat. Always use waxes and polishes that are non-abrasive and made for a basecoat/clearcoat paint ﬁnish. Foreign materials such as calcium chloride and other salts, ice melting agents, road oil and tar, tree sap, bird droppings, chemicals from industrial chimneys, etc., can damage the vehicle’s ﬁnish if they remain on painted surfaces. Wash the vehicle as soon as possible. If necessary, use non-abrasive cleaners that are marked safe for painted surfaces to remove foreign matter. Exterior painted surfaces are subject to aging, weather, and chemical fallout that can take their toll over a period of years. To help keep the paint ﬁnish looking new, keep the vehicle in a garage 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 or Chrome-Plated Wheels The vehicle may be equipped with either aluminum or chrome-plated wheels. Keep the wheels clean using a soft clean cloth with mild soap and water. Rinse with clean water. After rinsing thoroughly, dry with a soft clean towel. A wax may then be applied. Notice: 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. The surface of these wheels is similar to the painted surface of your vehicle. Do not use strong soaps, chemicals, abrasive polishes, abrasive cleaners, cleaners with acid, or abrasive cleaning brushes on them because you could damage the surface. Do not use chrome polish on aluminum wheels. 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. If you drive your vehicle through an Use chrome polish only on chrome-plated wheels, but avoid any painted surface of the wheel, and buff off immediately after application. 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 your 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 Sheet Metal Damage If the vehicle is damaged and requires sheet metal repair or replacement, make sure the body repair shop applies anti-corrosion material to parts repaired or replaced to restore corrosion protection. Original manufacturer replacement parts will provide the corrosion protection while maintaining the warranty. Finish Damage Any stone chips, fractures or deep scratches in the ﬁnish should be repaired right away. Bare metal will corrode quickly and may develop into major repair expense. Minor chips and scratches can be repaired with touch-up materials available from your GM dealer. Larger areas of ﬁnish damage can be corrected in your GM dealer’s body and paint shop. Underbody Maintenance Chemicals used for ice and snow removal and dust control can collect on the underbody. If these are not removed, corrosion and rust can develop on the underbody parts such as fuel lines, frame, ﬂoor pan, and exhaust system even though they have corrosion protection. At least every spring, ﬂush these materials from the underbody with plain water. Clean any areas where mud and debris can collect. Dirt packed in close areas of the frame should be loosened before being ﬂushed. Your dealer or an underbody car washing system can do this for you. Chemical Paint Spotting Some weather and atmospheric conditions can create a chemical fallout. Airborne pollutants can fall upon and attack painted surfaces on the vehicle. This damage can take two forms: blotchy, ring-shaped discolorations, and small, irregular dark spots etched into the paint surface. Although no defect in the paint job causes this, GM will repair, at no charge to the owner, the surfaces of new vehicles damaged by this fallout condition within 12 months or 12,000 miles (20 000 km) of purchase, whichever occurs ﬁrst. 5-89 Vehicle Care/Appearance Materials Description Usage Description Usage Polishing Cloth Wax-Treated Tar and Road Oil Remover Chrome Cleaner and Polish White Sidewall Tire Cleaner Vinyl Cleaner Glass Cleaner Chrome and Wire Wheel Cleaner Finish Enhancer Interior and exterior polishing cloth.

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 the VIN is the engine code. This code will help you identify your vehicle’s engine, speciﬁcations, and replacement parts. Service Parts Identiﬁcation Label You will ﬁnd this label on your spare tire cover. 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 airbag system. Before attempting to add anything electrical to your vehicle, see Servicing Your Airbag-Equipped Vehicle on page 1-70. Headlamp Wiring The headlamp wiring system has four individual fuses. An electrical overload will cause the lamps to go on and off, or in some cases to remain off. If this happens, have the headlamp wiring checked right away. Windshield Wiper Fuses The windshield wiper motor is protected by an internal circuit breaker. If the wiper motor overheats due to heavy snow, the wipers will stop until the motor cools and will then restart. A fuse powers the wiper motor. If the fuse blows, there is an electrical problem. Be sure to have it ﬁxed. 5-92 Power Windows and Other Power Options Circuit breakers protect the power windows and power seats. When the current load is too heavy, the circuit breaker opens and closes, protecting the circuit until the problem is ﬁxed or goes away. Fuses and Circuit Breakers The wiring circuits in your vehicle are protected from short circuits by a combination of fuses 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 a fuse should blow, see your dealer for service immediately. If you ever have a problem on the road and do not have a spare fuse, you can “borrow” one that has the same amperage. 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. The fuses are located in two fuse blocks, one located in the engine compartment, and the other under the rear seat. If a fuse should blow, have your vehicle serviced by your dealer immediately. Underhood Fuse Block The underhood fuse block is located on the passenger’s side of the engine compartment. Remove the fuse cover and secondary service cover to access the fuse block. 5-93 Fuses F1 F2 F3 F4 Usage Spare Driver’s Side Low Beam Passenger’s Side Low Beam Airbag Fuses F5 F6 F7 F8 Usage Powertrain Control Module Transaxle Spare Spare 5-94 Fuses Usage J-Case Fuse Usage F9 F10 F11 F12 F13 F14 F15 F16 F17 F18 F19 F20 F21 F22 F23 F24 F25 F26 F27 F28 F29 F30 F31 F32 Spare High Beam Headlamp High Beam Headlamp Windshield Washer Pump Spare Climate Controls Spare Fog Lamps Horn Windshield Wiper Lamp Lamp Oxygen Sensor Powertrain Engine Control Module Crank Electric Ignition Air Conditioning Air Solenoid Engine Control Module, Transaxle Control Module Spare Spare Spare Spare JC1 JC2 JC3 JC4 JC5 JC6 JC7 JC8 Relay R1 R2 R3 R4 R5 R6 R7 R8 R9 R10 R11 R12 Heated Windshield Washer Cooling Fan High Spare Crank Cooling Fan Low Anti-lock Brake System 2 Anti-lock Brake System 1 Air Pump Usage Cooling Fan 1 Cooling Fan 2 Crank Powertrain Spare Ignition Cooling Fan 3 Windshield Wiper Air Pump Windshield Wiper High Air Conditioning Air Control 5-95 If you touch the exposed wires with the Rear Underseat Fuse Block The rear fuse block is located under the rear seat on the driver’s side. The rear seat cushion must be removed to access the rear fuse block. Removing the Rear Seat Cushion Notice: metal on the seat cushion, you could cause a short that could damage the battery and or wires. Avoid contact between the rear seat and the fuse center whenever you remove or reinstall the rear seat. Do not remove covers from any of the covered parts, and do not store anything under the seats. To remove the rear seat cushion, do the following: 1. Pull up on the front of the cushion to release the front hooks. 2. Pull the cushion up and out toward the front of the vehicle. 5-96 To access the fuse block, pull out and lift up on the cover latch, located at the end of the fuse block, near the battery cable. To reinstall the rear seat cushion, do the following: {CAUTION: A safety belt that is not properly routed through the seat cushion or is twisted will not provide the protection needed in a crash. If the (Continued) CAUTION: CAUTION: (Continued) safety belt has not been routed through the seat cushion at all, it will not be there to work for the next passenger. The person sitting in that position could be badly injured. After reinstalling the seat cushion, always check to be sure that the safety belts are properly routed and are not twisted. 1. Buckle the center passenger position safety belt, then route the safety belts through the proper slots in the seat cushion. Do not let the safety belts get twisted. 2. Slide the rear of the cushion up and under the seatback so the rear-locating guides hook into the wire loops on the back frame. 3. With the seat cushion lowered, push rearward and then press down on the seat cushion until the spring locks on both ends engage. 4.

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. 6-2 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. Using the 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 4-31. 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 6-7 for further information. {CAUTION: Performing maintenance work on a vehicle can be dangerous. In trying to do some jobs, you can be seriously injured. Do your own maintenance work only if you have the required know-how and the proper tools and equipment for the job. If you have any doubt, see your GM Goodwrench® dealer to have a qualiﬁed technician do the work. Some maintenance services can be complex. So, unless you are technically qualiﬁed and have the necessary equipment, you should have your GM Goodwrench® dealer do these jobs. 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 7-14. Owner Checks and Services on page 6-9 tells you what should be checked, when to check it, and what you can easily do to help keep your vehicle in good condition. The proper replacement parts, ﬂuids, and lubricants to use are listed in Recommended Fluids and Lubricants on page 6-12 and Normal Maintenance Replacement Parts on page 6-13. 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. 6-3 (cid:127) (cid:127) (cid:127) Scheduled Maintenance When the CHANGE ENGINE OIL SOON message in the Driver Information Center (DIC) comes on, it means that service is required for your vehicle. Have your vehicle serviced as soon as possible within the next 600 miles (1 000 km). It is possible that, if you are driving under the best conditions, the engine oil life system may not indicate that vehicle service is necessary for over a year. However, your engine oil and ﬁlter must be changed at least once a year and at this time the system must be reset. Your GM Goodwrench® dealer has GM-trained service technicians who will perform this work using genuine GM parts and reset the system. If the engine oil life system is ever reset accidentally, you must service your vehicle within 3,000 miles (5 000 km) since your last service. Remember to reset the oil life system whenever the oil is changed. See Engine Oil Life System on page 5-16 for information on the Engine Oil Life System and resetting the system. When the CHANGE ENGINE OIL SOON message appears, certain services, checks, and inspections are required. Required services are described in the following for “Maintenance I” and “Maintenance II.” Generally, it is recommended that 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 SOON message 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. Always use Maintenance II whenever the message comes on 10 months or more since the last service or if the message has not come on at all for one year. 6-4 Scheduled Maintenance Service Maintenance I Maintenance II Change engine oil and ﬁlter.

We, however, urge that all recommended maintenance services be performed at the indicated intervals and the maintenance be recorded. (a) Visually inspect brake lines and hoses for proper hook-up, binding, leaks, cracks, chaﬁng, etc. Inspect disc brake pads for wear and rotors for surface condition. Inspect other brake parts, including calipers, parking brake, etc. (b) Visually inspect front and rear suspension and steering system for damaged, loose, or missing parts or signs of wear. Inspect power steering lines and hoses for proper hook-up, binding, leaks, cracks, chaﬁng, etc. 6-7 (c) Visually inspect hoses and have them replaced if they are cracked, swollen, or deteriorated. Inspect all pipes, ﬁttings and clamps; replace with genuine GM parts as needed. To help ensure proper operation, a pressure test of the cooling system and pressure cap and cleaning the outside of the radiator and air conditioning condenser is recommended at least once a year. (d) Visually inspect wiper blades for wear or cracking. Replace wiper blades that appear worn or damaged or that streak or miss areas of the windshield. (e) Make sure the safety belt reminder light and all your belts, buckles, latch plates, retractors, and anchorages are working properly. Look for any other loose or damaged safety belt system parts. If you see anything that might keep a safety belt system from doing its job, have it repaired. Have any torn or frayed safety belts replaced. Also look for any opened or broken airbag coverings, and have them repaired or replaced. The airbag system does not need regular maintenance. (f) Lubricate all key lock cylinders. Lubricate all hinges and latches, including those for the hood, rear compartment, glove box door, and console door. More frequent lubrication may be required when exposed to a corrosive environment. Applying silicone grease on weatherstrips with a clean cloth will make them last longer, seal better, and not stick or squeak. (g) If you drive regularly under dusty conditions, the ﬁlter may require replacement more often. 6-8 (h) Change automatic transaxle ﬂuid and ﬁlter if the vehicle is mainly driven under one or more of these conditions: − In heavy city traffic where the outside temperature regularly reaches 90°F (32°C) or higher. − In hilly or mountainous terrain. − When doing frequent trailer towing. − Professional vehicle uses, such as limousine service. − Uses such as high performance operation. (j) Drain, ﬂush, and reﬁll cooling system. This service can be complex; you should have your dealer perform this service. See Engine Coolant on page 5-22 for what to use. Inspect hoses. Clean radiator, condenser, pressure cap, and ﬁller neck. Pressure test the cooling system and pressure cap. (k) A ﬂuid loss in any vehicle system could indicate a problem. Have the system inspected and repaired and the ﬂuid level checked. Add ﬂuid if needed. (l) Inspect throttle body bore and valve plates for deposits. Open the throttle valve and inspect all surfaces. Clean as required. (m) If you drive regularly under dusty conditions, inspect the ﬁlter at each engine oil change. (n) Visually inspect belt for fraying, excessive cracks, or obvious damage. Replace belt if necessary. Owner Checks and Services These owner checks and services should be performed at the intervals speciﬁed to help ensure the safety, dependability, and emission control performance of your vehicle. Your GM Goodwrench® dealer can assist you with these checks and services. Be sure any necessary repairs are completed at once. Whenever any ﬂuids or lubricants are added to your vehicle, make sure they are the proper ones, as shown in Recommended Fluids and Lubricants on page 6-12. At Each Fuel Fill It is important to perform these underhood checks at each fuel ﬁll. Engine Oil Level Check Check the engine oil level and add the proper oil if necessary. See Engine Oil on page 5-13 for further details. Notice: and keep it at the proper level. Failure to keep your engine oil at the proper level can cause damage to your engine not covered by your warranty. It is important to check your oil regularly Engine Coolant Level Check Check the engine coolant level and add DEX-COOL® coolant mixture if necessary. See Engine Coolant on page 5-22 for further details. Windshield Washer Fluid Level Check Check the windshield washer ﬂuid level in the windshield washer ﬂuid reservoir and add the proper ﬂuid if necessary. At Least Once a Month Tire Inﬂation Check Visually inspect your vehicle’s tires and make sure they are inﬂated to the correct pressures. Do not forget to check the spare tire. See Tires on page 5-49 for further details. Check to make sure the spare tire is stored securely. See Changing a Flat Tire on page 5-72. Tire Wear Inspection Tire rotation may be required for high mileage highway drivers prior to the Engine Oil Life System service notiﬁcation. Check the tires for wear and, if necessary, rotate the tires. See Tire Inspection and Rotation on page 5-63. 6-9 At Least Once a Year Starter Switch Check {CAUTION: When you are doing this inspection, the vehicle could move suddenly. If the vehicle moves, you or others could be injured. 1. Before you start, be sure you have enough room around the vehicle. 2. Firmly apply both the parking brake and the regular brake. See Parking Brake on page 2-29. Do not use the accelerator pedal, and be ready to turn off the engine immediately if it starts. 3. Try to start the engine in each gear. The vehicle should start only in PARK (P) or NEUTRAL (N). If the vehicle starts in any other position, contact your GM Goodwrench® dealer for service. Automatic Transaxle Shift Lock Control System Check {CAUTION: When you are doing this inspection, the vehicle could move suddenly. If the vehicle moves, you or others could be injured. 1. Before you start, be sure you have enough room around the vehicle. It should be parked on a level surface. 2. Firmly apply the parking brake. See Parking Brake on page 2-29. Be ready to apply the regular brake immediately if the vehicle begins to move. 3. With the engine off, turn the ignition to RUN, but do not start the engine. Without applying the regular brake, try to move the shift lever out of PARK (P) with normal effort. If the shift lever moves out of PARK (P), contact your GM Goodwrench® dealer for service. 6-10 Ignition Transaxle Lock Check While parked, and with the parking brake set, try to turn the ignition to OFF in each shift lever position. The ignition should turn to OFF only when the shift lever is in PARK (P). The key should come out only in OFF. Contact your GM Goodwrench® dealer if service is required. Parking Brake and Automatic Transaxle Park (P) Mechanism Check {CAUTION: When you are doing this check, your vehicle could begin to move. You or others could be injured and property could be damaged. Make sure there is room in front of your vehicle in case it begins to roll. Be ready to apply the regular brake at once should the vehicle begin to move.
