5. As soon as you’ve cleaned the section, use a sponge to remove any excess cleaner. 6. Wipe cleaned area with a clean, water–dampened towel or cloth. 7. Wipe with a clean cloth and let dry. Special Fabric Cleaning Problems Stains caused by such things as catsup, coffee (black), egg, fruit, fruit juice, milk, soft drinks, vomit, urine and blood can be removed as follows: 1. Carefully scrape off excess stain, then sponge the soiled area with cool water. 2. If a stain remains, follow the cleaner instructions described earlier. 3. If an odor lingers after cleaning vomit or urine, treat the area with a water/baking soda solution: 1 teaspoon (5 ml) of baking soda to 1 cup (250 ml) of lukewarm water. 4. Let dry. Stains caused by candy, ice cream, mayonnaise, chili sauce and unknown stains can be removed as follows: 1. Carefully scrape off excess stain. 2. First, clean with cool water and allow to dry completely. 3. If a stain remains, follow the cleaner instructions described earlier. 5-91 (cid:127) Cleaning Interior Plastic Components Use only a mild soap and water solution on a soft cloth or sponge. Commercial cleaners may affect the surface ﬁnish. Cleaning the Speaker Covers Vacuum around a speaker cover gently, so that the speaker won’t be damaged. Clean spots with just water and mild soap. Cleaning Glass Surfaces Glass should be cleaned often. GM Glass Cleaner or a liquid household glass cleaner will remove normal tobacco smoke and dust ﬁlms on interior glass. See Vehicle Care/Appearance Materials on page 5-96. Notice: cleaning glass surfaces on your vehicle, you could scratch the glass and/or cause damage to the rear window defogger and the integrated radio antenna. When cleaning the glass on your vehicle, use only a soft cloth and glass cleaner. If you use abrasive cleaners when Cleaning Vinyl Use warm water and a clean cloth. (cid:127) Rub with a clean, damp cloth to remove dirt. You may have to do this more than once. Things like tar, asphalt and shoe polish will stain if you don’t get them off quickly. Use a clean cloth and vinyl cleaner. See your dealer for this product. Cleaning Leather Use a soft cloth with lukewarm water and a mild soap or saddle soap and wipe dry with a soft cloth. Then, let the leather dry naturally. Do not use heat to dry. For stubborn stains, use a leather cleaner. (cid:127) Never use oils, varnishes, solvent-based or abrasive cleaners, furniture polish or shoe polish on leather. (cid:127) Soiled or stained leather should be cleaned immediately. If dirt is allowed to work into the ﬁnish, it can harm the leather. Cleaning the Top of the Instrument Panel Use only mild soap and water to clean the top surfaces of the instrument panel. Sprays containing silicones or waxes may cause annoying reﬂections in the windshield and even make it difficult to see through the windshield under certain conditions. 5-92 (cid:127) (cid:127) Care of Safety Belts Keep belts clean and dry. {CAUTION: Do not bleach or dye safety belts. If you do, it may severely weaken them. In a crash, they might not be able to provide adequate protection. Clean safety belts only with mild soap and lukewarm water. Weatherstrips Silicone grease on weatherstrips will make them last longer, seal better, and not stick or squeak. Apply silicone grease with a clean cloth at least every six months. During very cold, damp weather more frequent application may be required. See Part D: Recommended Fluids and Lubricants on page 6-25. Cleaning the Outside of Your Vehicle The paint ﬁnish on your vehicle provides beauty, depth of color, gloss retention and durability. Washing Your Vehicle The best way to preserve your vehicle’s ﬁnish is to keep it clean by washing it often with lukewarm or cold water. Do not wash your vehicle in the direct rays of the sun. Use a car washing soap. Do not use strong soaps or chemical detergents. Be sure to rinse the vehicle well, removing all soap residue completely. You can get GM-approved cleaning products from your dealer. See Vehicle Care/Appearance Materials on page 5-96. Do not use cleaning agents that are petroleum based, or that contain acid or abrasives. All cleaning agents should be ﬂushed promptly and not allowed to dry on the surface, or they could stain. Dry the ﬁnish with a soft, clean chamois or an all-cotton towel to avoid surface scratches and water spotting. High pressure car washes may cause water to enter your vehicle. 5-93 Cleaning Exterior Lamps/Lenses Use only lukewarm or cold water, a soft cloth and a car washing soap to clean exterior lamps and lenses. Follow instructions under “Washing Your Vehicle.” Finish Care Occasional waxing or mild polishing of your vehicle by hand may be necessary to remove residue from the paint ﬁnish. You can get GM-approved cleaning products from your dealer. See Vehicle Care/Appearance Materials on page 5-96. 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. Cleaning Windshield and Wiper Blades If the windshield is not clear after using the windshield washer, or if the wiper blade chatters when running, wax, sap or other material may be on the blade or windshield. Clean the outside of the windshield with a full-strength glass cleaning liquid. The windshield is clean if beads do not form when you rinse it with water. Grime from the windshield will stick to the wiper blades and affect their performance. Clean the blade by wiping vigorously with a cloth soaked in full-strength windshield washer solvent. Then rinse the blade with water. Check the wiper blades and clean them as necessary; replace blades that look worn. 5-94 Cleaning Aluminum or Chrome-Plated Wheels Your vehicle may be equipped with either aluminum or chrome-plated wheels. Keep your wheels clean using a soft clean cloth with mild soap and water. Rinse with clean water. After rinsing thoroughly, dry with a soft clean towel. A wax may then be applied. The surface of these wheels is similar to the painted surface of your vehicle. Do not use strong soaps, chemicals, abrasive polishes, abrasive cleaners, cleaners with acid, or abrasive cleaning brushes on them because you could damage the surface. Do not use chrome polish on aluminum wheels. Use chrome polish only on chrome-plated wheels, but avoid any painted surface of the wheel, and buff off immediately after application. Do not take your vehicle through an automatic car wash that has silicone carbide tire cleaning brushes. These brushes can also damage the surface of these wheels. Cleaning Tires To clean your tires, use a stiff brush with tire cleaner. Notice: Using petroleum-based tire dressing products on your vehicle may damage the paint ﬁnish and/or tires. When applying a tire dressing, always wipe off any overspray from all painted surfaces on your vehicle. Sheet Metal Damage If your vehicle is damaged and requires sheet metal repair or replacement, make sure the body repair shop applies anti-corrosion material to parts repaired or replaced to restore corrosion protection. Original manufacturer replacement parts will provide the corrosion protection while maintaining the warranty. 5-95 Finish Damage Any stone chips, fractures or deep scratches in the ﬁnish should be repaired right away. Bare metal will corrode quickly and may develop into major repair expense. Minor chips and scratches can be repaired with touch-up materials avaliable from your dealer. Larger areas of ﬁnish damage can be corrected in your dealer’s body and paint shop. Underbody Maintenance Chemicals used for ice and snow removal and dust control can collect on the underbody. If these are not removed, corrosion and rust can develop on the underbody parts such as fuel lines, frame, ﬂoor pan and exhaust system even though they have corrosion protection. At least every spring, ﬂush these materials from the underbody with plain water. Clean any areas where mud and debris can collect. Dirt packed in close areas of the frame should be loosened before being ﬂushed. Your dealer or an underbody car washing system can do this for you. Chemical Paint Spotting Some weather and atmospheric conditions can create a chemical fallout. Airborne pollutants can fall upon and attack painted surfaces on your vehicle. This damage can take two forms: blotchy, ring-shaped discolorations, and small, irregular dark spots etched into the paint surface. Although no defect in the paint job causes this, GM will repair, at no charge to the owner, the surfaces of new vehicles damaged by this fallout condition within 12 months or 12,000 miles (20 000 km) of purchase, whichever occurs ﬁrst.

See Part D: Recommended Fluids and Lubricants on page 6-25. 5-97 Vehicle Identiﬁcation Vehicle Identiﬁcation Number (VIN) This is the legal identiﬁer for your vehicle. It appears on a plate in the front corner of the instrument panel, on the driver’s side. You can see it if you look through the windshield from outside your vehicle. The VIN also appears on the Vehicle Certiﬁcation and Service Parts labels and the certiﬁcates of title and registration. Engine Identiﬁcation The 8th character in your VIN is the engine code. This code will help you identify your engine, speciﬁcations and replacement parts. 5-98 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. Electrical System Add-On Electrical Equipment Notice: Don’t add anything electrical to your vehicle unless you check with your dealer ﬁrst. Some electrical equipment can damage your vehicle and the damage wouldn’t be covered by your warranty. Some add-on electrical equipment can keep other components from working as they should. Your vehicle has an air bag system. Before attempting to add anything electrical to your vehicle, see Servicing Your Air Bag-Equipped Vehicle on page 1-58. 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 damage 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. There are four fuse blocks in your vehicle: the main and auxiliary instrument panel fuse blocks, the underhood fuse block and the rear fuse block. Main and Auxiliary Instrument Panel Fuse Blocks The main and auxiliary instrument panel fuse blocks are located under the instrument panel, on the passenger’s side of the vehicle. Lamps, connectors and the HVAC duct temperature sensors may need to be disconnected and removed to allow access to these fuse blocks. Remove the hush panel on the passenger’s side to reveal the fuses by performing the following steps: 1. Remove the two screws located along the front edge of the panel. 2. Lower the hush panel. 3. Remove the fuse block cover. 4. Place the wide end of the fuse puller over the plastic end of the fuse. 5. Squeeze the ends over the fuse and pull it out. When ﬁnished, reinstall the fuse block cover and the hush panel. Reinstall lamps, connectors and HVAC duct temperature sensors if they were removed. 5-99 Main Instrument Panel Fuse Block Fuses Usage IGN SEN ELC ABS HVAC Auto Dimming Mirror, Driver HTS Seat, Rear Defog Relay, MEM Module, Cool LVL Sensor, Pass Heated Seat HVAC Flat Pk Mtrs, Electronic Level Control Sensor, Electronic Level Control Sensor (R Bec) Anti-Lock Brake System Module HVAC Main Con Head, HVAC Programmer, Instrument Panel Cluster CR CONT Stepper Motor Cruise, Cruise Switch HUD CSTR/SBM LP PK L Head-Up Display Switch, Head-Up Display HVAC Programmer, Instrument Panel Cluster, SBM (275 to LCM) (1135 to BTSI SL) Underhood Lamp, Left Park/ Sidemarker, Left Park/Turn Lamp, SBM, Left Tail Signal Lamp, Left Tail/Stoplamp, Left Rear Sidemarker Fuses Usage Interior Lamps PDM Module HVAC Motor, HVAC Mix Motors SBM PDM A/C 5-100 Fuses Usage Auxiliary Instrument Panel Fuse Block LP PK R RUN WSW Blank Right Park/Sidemarker Lamp, Right ParK/Turn Lamp, Right Tail/Sign Lamp, Right Tail/Stoplamp, Right Rear Sidemarker, Stop/Taillamp, Tail/Signal Lamp, License Lamp, RFA Run/Accessory Wiper Motor Not Used WSW/RFA Wiper Switch, RFA, Rain Sense B/U LP Auto Dimming Mirror, Back-Up Lamps Fuses Usage PERIM LP Perimeter Lamps ACCY IGN 3 Accessory Ignition 3 5-101 Underhood Fuse Block There are additional fuses located in the engine compartment on the passenger’s side of the vehicle.

Avoid contact between the rear seat and the fuse center whenever you remove or reinstall the rear seat. 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. To reinstall the rear seat cushion, do the following: {CAUTION: A safety belt that isn’t properly routed through the seat cushion or is twisted won’t provide the protection needed in a crash. If the safety belt hasn’t been routed through the seat cushion at all, it won’t 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. 5-104 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. Check to make sure the safety belts are properly routed and that no portion of any safety belt is trapped under the seat. Also make sure the seat cushion is secured. 5-105 Rear Compartment Fuse Block Additional fuses are located in the fuse center under the rear 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 Maintenance intervals, checks, inspections and recommended ﬂuids and lubricants as prescribed in this manual are necessary to keep your vehicle in good working condition. Any damage caused by failure to follow scheduled maintenance may not be covered by warranty. Your Vehicle and the Environment Proper vehicle maintenance not only helps to keep your vehicle in good working condition, but also helps the environment. Improper vehicle maintenance can even affect the quality of the air we breathe. Improper ﬂuid levels or the wrong tire inﬂation can increase the level of emissions from your vehicle. To help protect our environment, and to keep your vehicle in good condition, be sure to maintain your vehicle properly. 6-2 “Part B: Owner Checks and Services” tells you what should be checked and when. It also explains what you can easily do to help keep your vehicle in good condition. “Part C: Periodic Maintenance Inspections” explains important inspections that your dealer’s service department can perform for you. “Part D: Recommended Fluids and Lubricants” lists some recommended products necessary to help keep your vehicle properly maintained. These products, or their equivalents, should be used whether you do the work yourself or have it done. “Part E: Maintenance Record” is a place for you to record and keep track of the maintenance performed on your vehicle. Keep your maintenance receipts. They may be needed to qualify your vehicle for warranty repairs. How This Section is Organized This maintenance schedule is divided into ﬁve parts: “Part A: Scheduled Maintenance Services” explains what to have done and how often. Some of these services can be complex, so unless you are technically qualiﬁed and have the necessary equipment, you should let your GM dealer’s service department do these jobs. Your GM dealer has GM-trained and supported service people that will perform the work using genuine GM parts. {CAUTION: Performing maintenance work on a vehicle can be dangerous. In trying to do some jobs, you can be seriously injured. Do your own maintenance work only if you have the required know-how and the proper tools and equipment for the job. If you have any doubt, have a qualiﬁed technician do the work. If you want to get the service information, see Service Publications Ordering Information on page 7-11. 6-3 Part A: Scheduled Maintenance Services In this part are scheduled maintenance services which are to be performed at the mileage intervals speciﬁed. Using Your Maintenance Schedule We at General Motors want to keep your vehicle in good working condition. But we do not know exactly how you will drive it. You may drive short distances only a few times a week. Or you may drive long distances all the time in very hot, dusty weather. You may use your vehicle in making deliveries. Or you may drive it to work, to do errands or in many other ways. Because of the different ways people use their vehicles, maintenance needs may vary. You may need more frequent checks and replacements. So please read the following and note how you drive. If you have questions on how to keep your vehicle in good condition, see your dealer. This part tells you the maintenance services you should have done and when to schedule them. When you go to your dealer for your service needs, you will know that GM-trained and supported service people will perform the work using genuine GM parts. The proper ﬂuids and lubricants to use are listed in Part D. Make sure whoever services your vehicle uses these. All parts should be replaced and all necessary repairs done before you or anyone else drives the vehicle. These schedules are for vehicles that: carry passengers and cargo within recommended limits. You will ﬁnd these on the tire and loading information label. See Loading Your Vehicle on page 4-33. are driven on reasonable road surfaces within legal driving limits. use the recommended fuel. See Gasoline Octane on page 5-4. 6-4 (cid:127) (cid:127) (cid:127) Selecting the Right Schedule First you’ll need to decide which of the two schedules is right for your vehicle. Here’s how to decide which schedule to follow: Short Trip/City Deﬁnition Follow the Short Trip/City Scheduled Maintenance if any one of these conditions is true for your vehicle: (cid:127) Most trips are less than 5 miles (8 km). This is particularly important when outside temperatures are below freezing. (cid:127) Most trips include extensive idling (such as frequent driving in stop-and-go traffic). (cid:127) You frequently tow a trailer or use a carrier on top of your vehicle. If the vehicle is used for delivery service, police, taxi or other commercial application. One of the reasons you should follow this schedule if you operate your vehicle under any of these conditions is that these conditions cause engine oil to break down sooner. Short Trip/City Intervals Every 3,000 Miles (5 000 km): Engine Oil and Filter Change (or 3 months, whichever occurs ﬁrst). Every 6,000 Miles (10 000 km): Tire Rotation. Every 15,000 Miles (25 000 km): Engine Air Cleaner Filter Inspection. Passenger Compartment Air Filter Replacement. Every 30,000 Miles (50 000 km): Engine Air Cleaner Filter Replacement. Supercharger Oil Check (or every 36 months, whichever occurs ﬁrst) (3800 Code 1 V6 engine only). Every 50,000 Miles (83 000 km): Automatic Transaxle Service (severe conditions only). Every 100,000 Miles (166 000 km): Spark Plug Wire Inspection. Spark Plug Replacement. Automatic Transaxle Service (normal conditions). Every 150 000 Miles (240 000 km): Cooling System Service (or every 60 months, whichever occurs ﬁrst). Engine Accessory Drive Belt Inspection. These intervals only summarize maintenance services. Be sure to follow the complete scheduled maintenance on the following pages. 6-5 (cid:127) Long Trip/Highway Deﬁnition Follow this scheduled maintenance only if none of the conditions from the Short Trip/City Scheduled Maintenance are true. Do not use this schedule if the vehicle is used for trailer towing, driven in a dusty area or used off paved roads. Use the Short Trip/City schedule for these conditions Driving a vehicle with a fully warmed engine under highway conditions will cause engine oil to break down slower. Long Trip/Highway Intervals Every 7,500 Miles (12 500 km): Engine Oil and Filter Change (or every 12 months, whichever occurs ﬁrst). Tire Rotation. Every 15,000 Miles (25 000 km): Engine Air Cleaner Filter Inspection. Passenger Compartment Air Filter Replacement. Every 30,000 Miles (50 000 km): Supercharger Oil Check (or every 36 months, whichever occurs ﬁrst) (3800 Code 1 V6 engine only). Engine Air Cleaner Filter Replacement. Every 50,000 Miles (83 000 km): Automatic Transaxle Service (severe conditions only). Every 100,000 Miles (166 000 km): Spark Plug Wire Inspection. Spark Plug Replacement. Automatic Transaxle Service (normal conditions). Every 150,000 Miles (240 000 km): Cooling System Service (or every 60 months, whichever occurs ﬁrst). Engine Accessory Drive Belt Inspection. These intervals only summarize maintenance services. Be sure to follow the complete scheduled maintenance on the following pages. 6-6 Short Trip/City Scheduled Maintenance The services shown in this schedule up to 100,000 miles (166 000 km) should be repeated after 100,000 miles (166 000 km) at the same intervals for the life of this vehicle. The services shown at 150,000 miles (240 000 km) should be repeated at the same interval after 150,000 miles (240 000 km) for the life of this vehicle. See Part B: Owner Checks and Services on page 6-19 and Part C: Periodic Maintenance Inspections on page 6-23. Footnotes † The U.S. Environmental Protection Agency or the California Air Resources Board has determined that the failure to perform this maintenance item will not nullify the emission warranty or limit recall liability prior to the completion of the vehicle’s useful life. We, however, urge that all recommended maintenance services be performed at the indicated intervals and the maintenance be recorded. * If your vehicle has the GM Oil Life System, a computer system lets you know when to change the oil and ﬁlter. This is based on engine revolutions and engine temperature, and not on mileage. Based on driving conditions, the mileage at which an oil change will be indicated can vary considerably. For the oil life system to work properly, you must reset the system every time the oil is changed. When the system has calculated that oil life has been diminished, it will indicate that an oil change is necessary. A CHANGE ENGINE OIL SOON message will come on. Change your oil as soon as possible within the next two times you stop for fuel. It is possible that, if you are driving under the best conditions, the oil life system may not indicate that an oil change 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. It is also important to check your oil regularly and keep it at the proper level. If the system is ever reset accidentally, you must change your oil at 3,000 miles (5 000 km) since your last oil change. Remember to reset the oil life system whenever the oil is changed. See Engine Oil on page 5-14 for information on resetting the system. Whenever the tires are rotated, the Check Tire Pressure System (if equipped) must be reset. + A good time to check your brakes is during tire rotation.

The services shown at 150,000 miles (240 000 km) should be repeated at the same interval after 150,000 miles (240 000 km) for the life of this vehicle. See Part B: Owner Checks and Services on page 6-19 and Part C: Periodic Maintenance Inspections on page 6-23. Footnotes † The U.S. Environmental Protection Agency or the California Air Resources Board has determined that the failure to perform this maintenance item will not nullify the emission warranty or limit recall liability prior to the completion of the vehicle’s useful life. We, however, urge that all recommended maintenance services be performed at the indicated intervals and the maintenance be recorded. * If your vehicle has the GM Oil Life System, a computer system lets you know when to change the engine oil and ﬁlter. This is based on engine revolutions and engine temperature, and not on mileage. Based on 6-14 driving conditions, the mileage at which an oil change will be indicated can vary considerably. For the oil life system to work properly, you must reset the system every time the oil is changed. When the system has calculated that oil life has been diminished, it will indicate that an oil change is necessary. A CHANGE ENGINE OIL SOON message will come on. Change your oil as soon as possible within the next two times you stop for fuel. It is possible that, if you are driving under the best conditions, the oil life system may not indicate that an oil change 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. It is also important to check your oil regularly and keep it at the proper level. If the system is ever reset accidentally, you must change your oil at 3,000 miles (5 000 km) since your last oil change. Remember to reset the oil life system whenever the oil is changed. See Engine Oil on page 5-14 for information on resetting the system. Whenever the tires are rotated, the Check Tire Pressure System (if equipped) must be reset. + A good time to check your brakes is during tire rotation.

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 Part D. At Each Fuel Fill It is important for you or a service station attendant 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 5-14 for further details. Engine Coolant Level Check Check the engine coolant level and add DEX-COOL® coolant mixture if necessary. See Engine Coolant on page 5-25 for further details. Windshield Washer Fluid Level Check Check the windshield washer ﬂuid level in the windshield washer tank and add the proper ﬂuid if necessary. See Windshield Washer Fluid on page 5-39 for further details. At Least Once a Month Tire Inﬂation Check Visually inspect your tires and make sure tires are inﬂated to the correct pressures. Don’t forget to check your spare tire. See Tires on page 5-62 for further details. Cassette Tape Player Service Clean cassette tape player. Cleaning should be done every 50 hours of tape play. See Audio System(s) on page 3-57 for further details. 6-19 Automatic Transaxle Check Check the transaxle ﬂuid level; add if needed. See Automatic Transaxle Fluid on page 5-23. A ﬂuid loss may indicate a problem. Check the system and repair if needed. At Least Once a Year Key Lock Cylinders Service Lubricate the key lock cylinders with the lubricant speciﬁed in Part D. Body Lubrication Service Lubricate all body door hinges. Also lubricate all hinges and latches, including those for the hood, glove box door and console door. Part D tells you what to use. More frequent lubrication may be required when exposed to a corrosive environment. At Least Twice a Year Restraint System Check Make sure the safety belt reminder light and all your belts, buckles, latch plates, retractors and anchorages are working properly. Look for any other loose or damaged safety belt system parts. If you see anything that might keep a safety belt system from doing its job, have it repaired. Have any torn or frayed safety belts replaced. Also look for any opened or broken air bag coverings, and have them repaired or replaced. (The air bag system does not need regular maintenance.) Wiper Blade Check Inspect wiper blades for wear or cracking. Replace blade inserts that appear worn or damaged or that streak or miss areas of the windshield. Also see “Windshield Wiper and Wiper Blades” under Cleaning the Outside of Your Vehicle on page 5-93. Weatherstrip Lubrication 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 more frequent application may be required. See Part D: Recommended Fluids and Lubricants on page 6-25. 6-20 Starter Switch Check {CAUTION: When you are doing this inspection, the vehicle could move suddenly. If the vehicle moves, you or others could be injured. 1. Before you start, be sure you have enough room around the vehicle. 2. Firmly apply both the parking brake and the regular brake. See Parking Brake on page 2-29 if necessary. Do not use the accelerator pedal, and be ready to turn off the engine immediately if it starts. 3. Try to start the engine in each gear. The starter should work only in PARK (P) or NEUTRAL (N). If the starter works in any other position, your vehicle needs 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 if necessary. Be ready to apply the regular brake immediately if the vehicle begins to move. 3. With the engine off, turn the key to the RUN position, but don’t 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), your vehicle needs service. 6-21 Ignition Transaxle Lock Check While parked, and with the parking brake set, try to turn the ignition key to LOCK in each shift lever position. The key should turn to LOCK only when the shift lever is in PARK (P). The key should come out only in LOCK. 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. Park on a fairly steep hill, with the vehicle facing downhill. Keeping your foot on the regular brake, set the parking brake. To check the parking brake’s holding ability: With the engine running and transaxle in NEUTRAL (N), slowly remove foot pressure from the regular brake pedal. Do this until the vehicle is held by the parking brake only. To check the PARK (P) mechanism’s holding ability: With the engine running, shift to PARK (P). Then release the parking brake followed by the regular brake. Underbody Flushing Service At least every spring, use plain water to ﬂush any corrosive materials from the underbody. Take care to clean thoroughly any areas where mud and other debris can collect. 6-22 (cid:127) (cid:127) (cid:127) (cid:127) Part C: Periodic Maintenance Inspections Listed in this part are inspections and services which should be performed at least twice a year (for instance, each spring and fall). You should let your dealer’s service department do these jobs. Make sure any necessary repairs are completed at once. Proper procedures to perform these services may be found in a service manual. See Service Publications Ordering Information on page 7-11. Steering, Suspension and Front Drive Axle Boot and Seal Inspection Inspect the front and rear suspension and steering system for damaged, loose or missing parts, signs of wear or lack of lubrication. Inspect the power steering lines and hoses for proper hook-up, binding, leaks, cracks, chaﬁng, etc. Clean and then inspect the drive axle boot seals for damage, tears or leakage. Replace seals if necessary. Exhaust System Inspection Inspect the complete exhaust system. Inspect the body near the exhaust system. Look for broken, damaged, missing or out-of-position parts as well as open seams, holes, loose connections or other conditions which could cause a heat build-up in the ﬂoor pan or could let exhaust fumes into the vehicle. See Engine Exhaust on page 2-34. 6-23 Fuel System Inspection Inspect the complete fuel system for damage or leaks. Engine Cooling System Inspection Inspect the hoses and have them replaced if they are cracked, swollen or deteriorated. Inspect all pipes, ﬁttings and clamps; replace as needed. Clean the outside of the radiator and air conditioning condenser. To help ensure proper operation, a pressure test of the cooling system and pressure cap is recommended at least once a year. Throttle System Inspection Inspect the throttle system for interference or binding, and for damaged or missing parts. Replace parts as needed. Replace any components that have high effort or excessive wear. Do not lubricate accelerator and cruise control cables. Brake System Inspection Inspect the complete system. 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. Check parking brake adjustment.
