The indicators for the turn signals will flash on and off. Your hazard flashers work no matter what position your key is in, and even if the key isn’t in. To turn off the flashers, press the button down again. When the flashers are on, your turn signals won’t work. Other Warning Devices If you carry reflective triangles, you can set one up at the side of the road about 300 feet (100 m) behind your vehicle. Your hazard warning flashers let you warn others. They also let police know you have a problem. Your front and rear turn signal lamps will flash on and off. 5-2 Jump Starting If your battery has run down, you may want to use another vehicle and some jumper cables to start your vehicle. But please use the following steps to do it safely. CAUTION: Batteries can hurt you. They can be dangerous because: D They contain acid that can burn you. D They contain gas that can explode or ignite. D They contain enough electricity to burn you. If you don’t follow these steps exactly, some or all of these things can hurt you. NOTICE: Ignoring these steps could result in costly damage to your vehicle that wouldn’t be covered by your warranty. The ACDelcoR battery in your vehicle has a built-in hydrometer. Do not charge, test or jump start the battery if the hydrometer looks clear or light yellow. Replace the battery when there is a clear or light yellow hydrometer and a cranking complaint. Trying to start your vehicle by pushing or pulling it won’t work, and it could damage your vehicle. 5-3 1. Check the other vehicle. It must have a 12-volt battery with a negative ground system. NOTICE: If the other system isn’t a 12-volt system with a negative ground, both vehicles can be damaged. 2. Get the vehicles close enough so the jumper cables can reach, but be sure the vehicles aren’t touching each other. If they are, it could cause a ground connection you don’t want. You wouldn’t be able to start your vehicle, and the bad grounding could damage the electrical systems. To avoid the possibility of the vehicles rolling, set the parking brake firmly on both vehicles involved in the jump start procedure. Put an automatic transaxle in PARK (P) and a manual transaxle in NEUTRAL before setting the parking brake. 3. Turn off the ignition on both vehicles. Unplug unnecessary accessories plugged into the cigarette lighter or accessory power outlet. Turn off all lamps that aren’t needed as well as radios. This will avoid sparks and help save both batteries. In addition, it could save your radio. 4. Open the hoods and locate the other vehicle’s battery and your vehicle’s remote positive (+) jump starting terminal in the box on the passenger side of the engine compartment. (Your vehicle’s battery isn’t under the hood.) CAUTION: An electric fan can start up even when the engine is not running and can injure you. Keep hands, clothing and tools away from any underhood electric fan. 5-4 5. Find the positive (+) and negative (-) terminals on each battery or remote terminal. You should always use the remote positive (+) terminal instead of the positive (+) terminal on your battery. See “Engine Compartment Overview” in the Index for more information on location. Lift and move the red positive (+) remote terminal cover away from the relay center. CAUTION: Using a match near a battery can cause battery gas to explode. People have been hurt doing this, and some have been blinded. Use a flashlight if you need more light. Be sure the battery has enough water. You don’t need to add water to the ACDelcoR battery installed in every new GM vehicle. But if a battery has filler caps, be sure the right amount of fluid is there. If it is low, add water to take care of that first. If you don’t, explosive gas could be present. Battery fluid contains acid that can burn you. Don’t get it on you. If you accidentally get it in your eyes or on your skin, flush the place with water and get medical help immediately. 5-5 6. Check that the jumper cables don’t have loose or missing insulation. If they do, you could get a shock. The vehicles could also be damaged. Before you connect the cables, here are some things you should know. Positive (+) will go to positive (+) and negative (-) will go to a heavy, unpainted metal engine part. Don’t connect positive (+) to negative (-) or you’ll get a short that would damage the battery and maybe other parts too. Also, don’t connect the negative (-) cable to the negative (-) terminal on the dead battery. CAUTION: Fans or other moving engine parts can injure you badly. Keep your hands away from moving parts once the engine is running. 5-6 7. Connect the red positive (+) cable to the remote positive (+) terminal of the vehicle with the dead battery. 8. Don’t let the other end touch metal. Connect it to the positive (+) terminal of the good battery. Use a remote positive (+) terminal if the vehicle has one. 9. Now connect the black negative (-) cable to the good battery’s negative (-) terminal. If you have the 4.0L V8 engine, your vehicle has a remote negative terminal, marked “GND”, located near the power steering fluid reservoir. Attach the cable to the remote negative terminal provided. Don’t let the other end of the negative (-) cable touch anything until the next step. The other end of the negative (-) cable doesn’t go to the dead battery. 10. If you have the 3.5L V6 engine, it goes to a heavy, unpainted metal part on the engine of the vehicle with the dead battery. Don’t allow the red and black handles in the jumper cable to touch each other. See “Engine Compartment Overview” in the Index for more information on location. 11. Now start the vehicle with the good battery and run the engine for a while. 12. Try to start the vehicle with the dead battery. If it won’t start after a few tries, it probably needs service. 5-7 13. Remove the cables in reverse order to prevent electrical shorting. Take care that they don’t touch each other or any other metal. Replace the red positive (+)remote terminal cover to its original position. Towing Your Vehicle CAUTION: To help avoid serious personal injury to you or others: D Never let passengers ride in a vehicle that is being towed. D Never tow faster than safe or posted speeds. D Never tow with damaged parts not fully secured. D Never get under your vehicle after it has been lifted by the tow truck. D Always secure the vehicle on each side with separate safety chains when towing it. D Use only the correct hooks. A. Remote Positive (+) Terminal B. Good Battery C. Heavy, Unpainted Metal Engine Part 5-8 NOTICE: Use the proper towing equipment to avoid damage to the bumper, fascia or fog lamp areas of the vehicle. With current trends in automotive styles and design, it is essential that the correct towing equipment is used to tow a vehicle. Your vehicle can be towed with wheel-lift or car-carrier equipment only. Consult your dealer or a professional towing service if you need to have your vehicle towed. See “Roadside Assistance” in the Index. Engine Overheating You will find a coolant temperature gage on your vehicle’s instrument panel. Your driver information center will also display messages about engine overheating. See “Engine Coolant Temperature Gage” in the Index. Overheated Engine Protection Operating Mode Should an overheated engine condition exist and the message HOT STOP ENGINE is displayed, an overheat protection mode which alternates firing groups of cylinders helps prevent engine damage. In this mode, you will notice a loss in power and engine performance. This operating mode allows your vehicle to be driven to a safe place in an emergency; you may drive up to 50 miles (80 km). Towing a trailer in the overheat protection mode should be avoided. NOTICE: After driving in the overheated engine protection operating mode, to avoid engine damage, allow the engine to cool before attempting any repair. The engine oil will be severely degraded. Repair the cause of coolant loss, change the oil and reset the oil life indicator. See “Engine Oil” in the Index. 5-9 If Steam Is Coming From Your Engine CAUTION: Steam from an overheated engine can burn you badly, even if you just open the hood. Stay away from the engine if you see or hear steam coming from it. Just turn it off and get everyone away from the vehicle until it cools down. Wait until there is no sign of steam or coolant before you open the hood. If you keep driving when your engine is overheated, the liquids in it can catch fire. You or others could be badly burned. Stop your engine if it overheats, and get out of the vehicle until the engine is cool. See “Overheated Engine Protection Operating Mode” in the Index. 5-10 NOTICE: If your engine catches fire because you keep driving with no coolant, your vehicle can be badly damaged. The costly repairs would not be covered by your warranty. See “Overheated Engine Protection Operating Mode” in the Index. If No Steam Is Coming From Your Engine If you get an engine overheat warning but see or hear no steam, the problem may not be too serious. Sometimes the engine can get a little too hot when you: D Climb a long hill on a hot day. D Stop after high-speed driving. D Idle for long periods in traffic. D Tow a trailer. If you get the overheat warning with no sign of steam, try this for a minute or so: 1. If your air conditioner is on, turn it off. 2. Turn on your heater to full hot at the highest fan speed and open the window as necessary. 3. If you’re in a traffic jam, shift to NEUTRAL (N); otherwise, shift to the highest gear while driving -- AUTOMATIC OVERDRIVE (D) or THIRD (3). If you no longer have the overheat warning, you can drive. Just to be safe, drive slower for about 10 minutes. If the warning doesn’t come back on, you can drive normally. If the warning continues, pull over, stop, and park your vehicle right away. If there’s still no sign of steam, idle the engine for three minutes while you’re parked. If you still have the warning, turn off the engine and get everyone out of the vehicle until it cools down. Also, see “Overheated Engine Protection Operating Mode” listed previously in this section. You may decide not to lift the hood but to get service help right away. 5-11 Cooling System When you decide it’s safe to lift the hood, here’s what you’ll see: CAUTION: An electric engine cooling fan under the hood can start up even when the engine is not running and can injure you. Keep hands, clothing and tools away from any underhood electric fan. If the coolant inside the coolant surge tank is boiling, don’t do anything else until it cools down. A. Coolant Surge Tank with Pressure Cap B. Two Electric Engine Cooling Fans 5-12 A low coolant level should be indicated by a CHECK COOLANT LEVEL message on the Driver Information Center. If it is, you may have a leak in the radiator hoses, heater hoses, radiator, water pump or somewhere else in the cooling system. CAUTION: Heater and radiator hoses, and other engine parts, can be very hot. Don’t touch them. If you do, you can be burned. Don’t run the engine if there is a leak. If you run the engine, it could lose all coolant. That could cause an engine fire, and you could be burned. Get any leak fixed before you drive the vehicle. NOTICE: Engine damage from running your engine without coolant isn’t covered by your warranty. See “Overheated Engine Protection Operating Mode” in the Index. NOTICE: When adding coolant, it is important that you use only DEX-COOLR (silicate-free) coolant. If coolant other than DEX-COOL is added to the system, premature engine, heater core or radiator corrosion may result. In addition, the engine coolant will require change sooner -- at 30,000 miles (50 000 km) or 24 months, whichever occurs first. Damage caused by the use of coolant other than DEX-COOLR is not covered by your new vehicle warranty. If there seems to be no leak, with the engine on, check to see if the electric engine cooling fans are running. If the engine is overheating, both fans should be running. If they aren’t, your vehicle needs service. 5-13 CAUTION: (Continued) cooling system, including the coolant surge tank pressure cap, is hot. Wait for the cooling system and coolant surge tank pressure cap to cool if you ever have to turn the pressure cap. How to Add Coolant to the Coolant Surge Tank If you haven’t found a problem yet, but the coolant level isn’t at at the proper level (below the base of the filler neck), add a 50/50 mixture of clean, drinkable water and DEX-COOLR coolant at the coolant surge tank, but be sure the cooling system, including the coolant surge tank pressure cap, is cool before you do it. See “Engine Coolant” in the Index for more information. CAUTION: Steam and scalding liquids from a hot cooling system can blow out and burn you badly. They are under pressure, and if you turn the coolant surge tank pressure cap -- even a little -- they can come out at high speed. Never turn the cap when the CAUTION: (Continued) 5-14 CAUTION: NOTICE: Adding only plain water to your cooling system can be dangerous. Plain water, or some other liquid like alcohol, can boil before the proper coolant mixture will. Your vehicle’s coolant warning system is set for the proper coolant mixture. With plain water or the wrong mixture, your engine could get too hot but you wouldn’t get the overheat warning. Your engine could catch fire and you or others could be burned. Use a 50/50 mixture of clean, drinkable water and DEX-COOLR coolant. In cold weather, water can freeze and crack the engine, radiator, heater core and other parts. So use the recommended coolant. CAUTION: You can be burned if you spill coolant on hot engine parts. Coolant contains ethylene glycol and it will burn if the engine parts are hot enough. Don’t spill coolant on a hot engine. 5-15 2. Then keep turning the pressure cap slowly, and remove it. 3. Then fill the coolant surge tank with the proper mixture, to the base of the filler neck. 1. You can remove the coolant surge tank pressure cap when the cooling system, including the coolant surge tank pressure cap and upper radiator hose, is no longer hot. Turn the pressure cap slowly counterclockwise (left) about one-quarter turn and then stop. If you hear a hiss, wait for that to stop. A hiss means there is still some pressure left. 5-16 4. With the coolant surge tank pressure cap off, start the engine and let it run until you can feel the upper radiator hose getting hot. Watch out for the engine cooling fans. By this time, the coolant level inside the coolant surge tank may be lower. If the level is lower, add more of the proper mixture to the coolant surge tank until the level reaches the base of the filler neck. 5. Then replace the pressure cap. Be sure the arrows on the pressure cap line up like this. 5-17 If a Tire Goes Flat It’s unusual for a tire to “blow out” while you’re driving, especially if you maintain your tires properly. If air goes out of a tire, it’s much more likely to leak out slowly. But if you should ever have a “blowout,” here are a few tips about what to expect and what to do: If a front tire fails, the flat tire will create a drag that pulls the vehicle toward that side. Take your foot off the accelerator pedal and grip the steering wheel firmly. Steer to maintain lane position, and then gently brake to a stop well out of the traffic lane. A rear blowout, particularly on a curve, acts much like a skid and may require the same correction you’d use in a skid. In any rear blowout, remove your foot from the accelerator pedal. Get the vehicle under control by steering the way you want the vehicle to go. It may be very bumpy and noisy, but you can still steer. Gently brake to a stop -- well off the road if possible. If a tire goes flat, the next part shows how to use your jacking equipment to change a flat tire safely. Changing a Flat Tire If a tire goes flat, avoid further tire and wheel damage by driving slowly to a level place. Turn on your hazard warning flashers. CAUTION: Changing a tire can cause an injury. The vehicle can slip off the jack and roll over you or other people. You and they could be badly injured. Find a level place to change your tire. To help prevent the vehicle from moving: 1. Set the parking brake firmly. 2. Put the shift lever in PARK (P). 3. Turn off the engine. To be even more certain the vehicle won’t move, you can put blocks at the front and rear of the tire farthest away from the one being changed. That would be the tire on the other side of the vehicle, at the opposite end. 5-18 Removing the Spare Tire and Tools The following steps will tell you how to use the jack and change a tire. The equipment you’ll need is in the trunk. Instructions for changing your tires are on the inside of the tire cover. You can rest the cover near you for easy reference while you change the tire. 1. Lift the tire cover to gain access to the spare tire and jacking equipment. See “Compact Spare Tire” later in this section for more information about the compact spare. 5-19 2. Remove the wheel wrench and jack from the jack container. 3. Remove the spare tire from the trunk. Removing the Wheel Cover The tools you’ll be using include the jack (A) and the wheel wrench (B). Insert the hooked end of the wheel wrench in one of the two small notches in the center cover and pry the cover off. Do not drop the cover or lay it face down, as it could be scratched or damaged. 5-20 Removing the Flat Tire and Installing the Spare Tire 3. Turn the wheel wrench counterclockwise by hand to lower the jack head until it fits under the vehicle. 1. Position the wheel wrench securely over the wheel nuts to loosen, but don’t remove them. 2. Attach the wheel wrench to the bolt on the end of the jack to create a jack handle. 5-21 CAUTION: Getting under a vehicle when it is jacked up is dangerous. If the vehicle slips off the jack, you could be badly injured or killed. Never get under a vehicle when it is supported only by a jack. CAUTION: Raising your vehicle with the jack improperly positioned can damage the vehicle and even make the vehicle fall. To help avoid personal injury and vehicle damage, be sure to fit the jack lift head into the proper location before raising the vehicle. 4. Near each wheel well is a notch in the frame to position the jack head. Position the jack under the vehicle and raise the jack head until it fits firmly against the sheet metal. Do not raise the vehicle yet. Put the compact spare near you. 5-22 5. Raise the vehicle by turning the wheel wrench clockwise on the jack. Raise the vehicle far enough off the ground so there’s enough room for the spare tire to fit. 6. Remove all the wheel nuts and take off the flat tire. 7. Remove any rust or dirt from the wheel bolts, mounting surfaces and spare wheel. CAUTION: Rust or dirt on the wheel, or on the parts to which it is fastened, can make the wheel nuts become loose after a time. The wheel could come off and cause an accident. When you change a wheel, remove any rust or dirt from the places where the wheel attaches to the vehicle. In an emergency, you can use a cloth or a paper towel to do this; but be sure to use a scraper or wire brush later, if you need to, to get all the rust or dirt off. CAUTION: Never use oil or grease on studs or nuts. If you do, the nuts might come loose. Your wheel could fall off, causing a serious accident. 5-23 8. Place the spare tire on the wheel-mounting surface. 9. 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. If a nut cannot be tightened by hand, use the wheel wrench, and see your dealer right away. 10. Lower the vehicle by turning the wheel wrench counterclockwise on the jack. Lower the jack completely. 5-24 11. Using the wheel wrench, tighten the wheel nuts firmly in a crisscross sequence as shown. CAUTION: Incorrect wheel nuts or improperly tightened wheel nuts can cause the wheel to become loose and even come off. This could lead to an accident. Be sure to use the correct wheel nuts. If you have to replace them, be sure to get new GM original equipment wheel nuts. Stop somewhere as soon as you can and have the nuts tightened with a torque wrench to 100 lb-ft (140 N·m). NOTICE: Improperly tightened wheel nuts can lead 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. 12. When the flat tire has been repaired or replaced, install the wheel cover. Be sure to position the alignment pin on the cover with the notch in the wheel. Apply pressure around the edge of the cap to snap it in place. Do not use a hammer or mallet to install the cover. Store the wheel cover in the trunk until you have replaced the compact spare tire with a regular tire. NOTICE: Wheel covers won’t fit on your compact spare. If you try to put a wheel cover on your compact spare, you could damage the cover or the spare. 5-25 Storing the Flat 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. 5-26 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. Storing the 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. The compact spare tire is for temporary use only. Replace the compact spare tire with a full-size tire as soon as you can. See “Compact Spare Tire” later in this section. See the storage instructions label to replace your compact spare into your trunk properly. 5-27 Compact Spare Tire Although the compact spare tire was fully inflated when your vehicle was new, it can lose air after a time. Check the inflation pressure regularly. It should be 60 psi (420 kPa). After installing the compact spare on your vehicle, you should stop as soon as possible and make sure your spare tire is correctly inflated. The compact spare is made to perform well at speeds up to 65 mph (105 km/h) for distances up to 3,000 miles (5 000 km), so you can finish your trip and have your full-size tire repaired or replaced where you want. You must calibrate the Check Tire Pressure System after installing or removing the compact spare. See “Check Tire Pressure System” in the Index. Of course, it’s best to replace your spare with a full-size tire as soon as you can. Your spare will last longer and be in good shape in case you need it again. NOTICE: When the compact spare is installed, don’t take your vehicle through an automatic car wash with guide rails. The compact spare can get caught on the rails. That can damage the tire and wheel, and maybe other parts of your vehicle. Don’t use your compact spare on other vehicles. And don’t mix your compact spare tire or wheel with other wheels or tires. They won’t fit. Keep your spare tire and its wheel together. NOTICE: Tire chains won’t fit your compact spare. Using them can damage your vehicle and can damage the chains too. Don’t use tire chains on your compact spare. 5-28 If You’re Stuck: In Sand, Mud, Ice or Snow In order to free your vehicle when it is stuck, you will need to spin the wheels, but you don’t want to spin your wheels too fast. The method known as “rocking” can help you get out when you’re stuck, but you must use caution. CAUTION: If you let your tires spin at high speed, they can explode, and you or others could be injured. And, the transaxle or other parts of the vehicle can overheat. That could cause an engine compartment fire or other damage. When you’re stuck, spin the wheels as little as possible. Don’t spin the wheels above 35 mph (55 km/h) as shown on the speedometer. NOTICE: Spinning your wheels can destroy parts of your vehicle as well as the tires. If you spin the wheels too fast while shifting your transaxle back and forth, you can destroy your transaxle. For information about using tire chains on your vehicle, see “Tire Chains” in the Index. Rocking Your Vehicle To Get It Out First, turn your steering wheel left and right. That will clear the area around your front wheels. You should turn your traction control system off. See “Traction Control System” in the Index. Then shift back and forth between REVERSE (R) and a forward gear, spinning the wheels as little as possible. Release the accelerator pedal while you shift, and press lightly on the accelerator pedal when the transaxle is in gear. By slowly spinning your wheels in the forward and reverse directions, you will cause a rocking motion that may free your vehicle. If that doesn’t get you out after a few tries, you may need to be towed out. If you do need to be towed out, see “Towing Your Vehicle” in the Index. 5-29 Section 6 Service and Appearance Care Here you will find information about the care of your vehicle. This section begins with service and fuel information, and then it shows how to check important fluid and lubricant levels. There is also technical information about your vehicle, and a part devoted to its appearance care. 6-2 6-3 6-10 6-10 6-15 6-20 6-23 6-26 6-31 6-32 6-35 6-37 6-48 Service Fuel Filling a Portable Fuel Container Checking Things Under the Hood Engine Oil Engine Air Cleaner/Filter Automatic Transaxle Fluid Engine Coolant Windshield Washer Fluid Brakes Battery Bulb Replacement Tires 6-58 6-58 6-62 6-64 6-64 6-65 6-66 6-67 6-71 6-75 6-76 6-78 Appearance Care Cleaning the Inside of Your Vehicle Cleaning the Outside of Your Vehicle Underbody Maintenance Chemical Paint Spotting GM Vehicle Care/Appearance Materials Vehicle Identification Number (VIN) Electrical System Removing the Rear Seat Cushion Replacement Bulbs Capacities and Specifications Normal Maintenance Replacement Parts 6- 6-1 Service Your dealer knows your vehicle best and wants you to be happy with it. We hope you’ll go to your dealer for all your service needs. You’ll get genuine GM parts and GM-trained and supported service people. We hope you’ll want to keep your GM vehicle all GM. Genuine GM parts have one of these marks: Doing Your Own Service Work If you want to do some of your own service work, you’ll want to use the proper service manual. It tells you much more about how to service your vehicle than this manual can. To order the proper service manual, see “Service and Owner Publications” in the Index. Your vehicle has an air bag system. Before attempting to do your own service work, see “Servicing Your Air Bag-Equipped Vehicle” in the Index. You should keep a record with all parts receipts and list the mileage and the date of any service work you perform. See “Maintenance Record” in the Index. 6-2 CAUTION: You can be injured and your vehicle could be damaged if you try to do service work on a vehicle without knowing enough about it. D Be sure you have sufficient knowledge, experience, the proper replacement parts and tools before you attempt any vehicle maintenance task. D Be sure to use the proper nuts, bolts and other fasteners. “English” and “metric” fasteners can be easily confused. If you use the wrong fasteners, parts can later break or fall off. You could be hurt. Adding Equipment to the Outside of Your Vehicle Things you might add to the outside of your vehicle can affect the airflow around it. This may cause wind noise and affect windshield washer performance. Check with your dealer before adding equipment to the outside of your vehicle. Fuel If you have the 3.5L V6 engine (VIN Code H), use regular unleaded gasoline rated at 87 octane or higher. If you have the 4.0L V8 engine (VIN Code C), use premium unleaded gasoline rated at 91 octane or higher for best performance. You may use middle grade or regular unleaded gasolines, but your vehicle’s acceleration may be slightly reduced. It is recommended that the gasoline meet specifications which have been developed by the American Automobile Manufacturers Association (AAMA) and endorsed by the Canadian Motor Vehicle Manufacturers Association for better vehicle performance and engine protection. Gasolines meeting the AAMA specification could provide improved driveability and emission control system performance compared to other gasolines. Be sure the posted octane for premium is at least 91 (at least 89 for middle grade and 87 for regular). If the octane is less than 87, you may get a heavy knocking noise when you drive. If it’s bad enough, it can damage your engine. 6-3 If you’re using fuel rated at the recommended octane or higher and you hear heavy knocking, your engine needs service. But don’t worry if you hear a little pinging noise when you’re accelerating or driving up a hill. That’s normal, and you don’t have to buy a higher octane fuel to get rid of pinging. It’s the heavy, constant knock that means you have a problem. If your vehicle is certified to meet California Emission Standards (indicated on the underhood emission control label), it is designed to operate on fuels that meet California specifications. If such fuels are not available in states adopting California emissions standards, your vehicle will operate satisfactorily on fuels meeting federal specifications, but emission control system performance may be affected. The malfunction indicator lamp on your instrument panel may turn on and/or your vehicle may fail a smog-check test. See “Malfunction Indicator Lamp” in the Index. If this occurs, return to your authorized Oldsmobile dealer for diagnosis to determine the cause of failure. In the event it is determined that the cause of the condition is the type of fuels used, repairs may not be covered by your warranty. Some gasolines that are not reformulated for low emissions may contain an octane-enhancing additive called methylcyclopentadienyl manganese tricarbonyl (MMT); ask your service station operator whether or not the fuel contains MMT. General Motors does not recommend the use of such gasolines. If fuels containing MMT are used, spark plug life may be reduced and your emission control system performance may be affected. The malfunction indicator lamp on your instrument panel may turn on. If this occurs, return to your authorized Oldsmobile dealer for service. 6-4 To provide cleaner air, all gasolines in the United States are now required to contain additives that will help prevent deposits from forming in your engine and fuel system, allowing your emission control system to function properly. Therefore, you should not have to add anything to the fuel. In addition, gasolines containing oxygenates, such as ethers and ethanol, and reformulated gasolines may be available in your area to contribute to clean air. General Motors recommends that you use these gasolines, particularly if they comply with the specifications described earlier. NOTICE: Your vehicle was not designed for fuel that contains methanol. Don’t use it. It can corrode metal parts in your fuel system and also damage plastic and rubber parts. That damage wouldn’t be covered under your warranty. Fuels in Foreign Countries If you plan on driving in another country outside the United States or Canada, the proper fuel may be hard to find. Never use leaded gasoline or any other fuel not recommended in the previous text on fuel. Costly repairs caused by use of improper fuel wouldn’t be covered by your warranty. To check on fuel availability, ask an auto club, or contact a major oil company that does business in the country where you’ll be driving. You can also write us at the following address for advice. Just tell us where you’re going and give your Vehicle Identification Number (VIN). General Motors Overseas Distribution Corporation 1908 Colonel Sam Drive Oshawa, Ontario L1H 8P7 6-5 Filling Your Tank CAUTION: Gasoline vapor is highly flammable. It burns violently, and that can cause very bad injuries. Don’t smoke if you’re near gasoline or refueling your vehicle. Keep sparks, flames and smoking materials away from gasoline. 6-6 The cap is behind a hinged door on the driver’s side of the vehicle. To open the fuel door, press the button located on the driver’s door trim near the trunk release button. To do so, first open the trunk. The release mechanism is located on the driver’s side of the vehicle, at the top of the trunk compartment. Pull the tab toward you to release the fuel door. The ignition does not need to be on. The remote fuel door release will work in all transaxle positions. The trunk release lockout switch must be in OFF for the fuel door to open. The fuel door can be opened manually in case of an electrical power failure. NOTICE: Prying on a locked fuel filler door could damage it. Use the remote fuel door manual release located in the trunk. 6-7 CAUTION: If you get gasoline on yourself and then something ignites it, you could be badly burned. Gasoline can spray out on you if you open the fuel filler cap too quickly. This spray can happen if your tank is nearly full, and is more likely in hot weather. Open the fuel filler cap slowly and wait for any “hiss” noise to stop. Then unscrew the cap all the way. Be careful not to spill gasoline. Clean gasoline from painted surfaces as soon as possible. See “Cleaning the Outside of Your Vehicle” in the Index. While refueling, hang the tethered cap from the hook on the fuel door. To remove the cap, turn it slowly to the left (counterclockwise). The cap has a spring in it; if you let go of the cap too soon, it will spring back to the right. 6-8 When you put the cap back on, turn it to the right (clockwise) until you hear a clicking sound. Make sure you fully install the cap. The diagnostic system can determine if the fuel cap has been left off or improperly installed. This would allow fuel to evaporate into the atmosphere. See “Malfunction Indicator Lamp” in the Index. The CHECK GAS CAP DIC message will come on if the fuel cap is not properly reinstalled. NOTICE: If you need a new cap, be sure to get the right type. Your dealer can get one for you. If you get the wrong type, it may not fit properly. This may cause your malfunction indicator lamp to light and your fuel tank and emissions system may be damaged. See “Malfunction Indicator Lamp” in the Index. 6-9 Filling a Portable Fuel Container Checking Things Under the Hood CAUTION: CAUTION: Never fill a portable fuel container while it is in your vehicle. Static electricity discharge from the container can ignite the gasoline vapor. You can be badly burned and your vehicle damaged if this occurs. To help avoid injury to you and others: D Dispense gasoline only into approved containers. D Do not fill a container while it is inside a vehicle, in a vehicle’s trunk, pickup bed or on any surface other than the ground. D Bring the fill nozzle in contact with the inside of the fill opening before operating the nozzle. Contact should be maintained until the filling is complete. D Don’t smoke while pumping gasoline. An electric fan under the hood can start up and injure you even when the engine is not running. Keep hands, clothing and tools away from any underhood electric fan. CAUTION: Things that burn can get on hot engine parts and start a fire. These include liquids like gasoline, oil, coolant, brake fluid, windshield washer and other fluids, and plastic or rubber. You or others could be burned. Be careful not to drop or spill things that will burn onto a hot engine. 6-10 Hood Release To open the hood, first pull the hood release handle, located to the left of the steering wheel under the instrument panel. Then go to the front of the vehicle and pull up on the secondary hood release. Lift the hood. Before closing the hood, be sure all the filler caps are on properly. Then pull the hood down and close it firmly. 6-11 Engine Compartment Overview 3.5L V6 Engine When you open the hood, you’ll see: 6-12 A. Underhood Bussed Electrical Center B.

Brake Fluid Reservoir K. Automatic Transaxle Fluid Dipstick (near the air cleaner) L. Engine Air Cleaner/Filter Engine Oil Checking Engine Oil It’s a good idea to check your engine oil every time you get fuel. In order to get an accurate reading, the oil must be warm and the vehicle must be on level ground. The top of the engine oil dipstick is a round yellow loop. If the CHECK OIL LEVEL message appears on the instrument panel, it means you need to check your engine oil level right away. For more information, see “DIC Warnings and Messages” in the Index. You should check your engine oil level regularly; this is an added reminder. See “Engine Compartment Overview” in the Index for more information on location. Turn off the engine and give the oil several minutes to drain back into the oil pan. If you don’t, the oil dipstick might not show the actual level. 6-15 When to Add Engine Oil If the oil is at or below the ADD line, then you’ll need to add at least one quart of oil. But you must use the right kind. This part explains what kind of oil to use. For crankcase capacity, see “Capacities and Specifications” in the Index. NOTICE: Don’t add too much oil. If your engine has so much oil that the oil level gets above the upper mark that shows the proper operating range, your engine could be damaged. Pull out the dipstick and clean it with a paper towel or cloth, then push it back in all the way. Remove it again, keeping the tip down, and check the level. 3.5L V6 Engine 4.0L V8 Engine 6-16 See “Engine Compartment Overview” in the Index for more information on location. What Kind of Engine Oil to Use Oils recommended for your vehicle can be identified by looking for the starburst symbol. This symbol indicates that the oil has been certified by the American Petroleum Institute (API). Do not use any oil which does not carry this starburst symbol. Be sure to fill it enough to put the level somewhere in the proper operating range. Push the dipstick all the way back in when you’re through. If you change your own oil, be sure you use oil that has the starburst symbol on the front of the oil container. If you have your oil changed for you, be sure the oil put into your engine is American Petroleum Institute certified for gasoline engines. You should also use the proper viscosity oil for your vehicle, as shown in the following chart: 6-17 As shown in the chart, SAE 5W-30 is best for your vehicle. However, you can use SAE 10W-30 if it’s going to be 0_F (-18_C) or above. These numbers on an oil container show its viscosity, or thickness. Do not use other viscosity oils, such as SAE 20W-50. NOTICE: Use only engine oil with the American Petroleum Institute Certified For Gasoline Engines starburst symbol. Failure to use the recommended oil can result in engine damage not covered by your warranty. GM GoodwrenchR oil meets all the requirements for your vehicle. If you are in an area where the temperature falls below -20_F (-29_C), consider using either an SAE 5W-30 synthetic oil or an SAE 0W-30 oil. Both will provide easier cold starting and better protection for your engine at extremely low temperatures. 6-18 Engine Oil Additives Don’t add anything to your oil. The recommended oils with the starburst symbol are all you will need for good performance and engine protection. When to Change Engine Oil Your vehicle has a computer that lets you know when to change your engine oil. This is not based on mileage, but on engine revolutions and engine operating temperature. When the computer has calculated that the oil needs changing, the GM Oil Life Systemt will indicate that a change is necessary. The mileage between oil and filter changes will vary depending on how you drive your vehicle -- usually between 3,000 miles (5 000 km) and 10,000 miles (16 000 km) since your last oil and filter change. Under severe conditions, the system may come on before 3,000 miles (5 000 km). Never drive your vehicle more than 10,000 miles (16 000 km) or 12 months (whichever occurs first) without an oil change. The system won’t detect dust in the oil. So, if you drive in a dusty area, be sure to change your oil and filter every 3,000 miles (5 000 km) or sooner. Remember to reset the Oil Life System whenever the oil is changed. How to Reset the Oil Life System Always reset the engine Oil Life System to 100% after every oil change. It will not reset itself. To reset the OIL LIFE reminder, do the following: 1. With the ignition on, press the SELECT right arrow button to OIL so the OIL LIFE percentage is displayed. 2. Press RESET and hold for five seconds. OIL LIFE XXX% will appear and then when the button is released OIL LIFE 100% will be displayed. 6-19 Engine Air Cleaner/Filter The engine air cleaner and filter are on the driver’s side of the engine compartment. See “Engine Compartment Overview” in the Index for more information on location. What to Do with Used Oil Did you know that used engine oil contains certain elements that may be unhealthy for your skin and could even cause cancer? Don’t let used oil stay on your skin for very long. Clean your skin and nails with soap and water, or a good hand cleaner. Wash or properly throw away clothing or rags containing used engine oil. See the manufacturer’s warnings about the use and disposal of oil products. Used oil can be a real threat to the environment. If you change your own oil, be sure to drain all free-flowing oil from the filter before disposal. Don’t ever dispose of oil by putting it in the trash, pouring it on the ground, into sewers, or into streams or bodies of water. Instead, recycle it by taking it to a place that collects used oil. If you have a problem properly disposing of your used oil, ask your dealer, a service station or a local recycling center for help. 6-20 To check or replace the air filter: 1. Using a Phillips screwdriver, unscrew the two wing screws on the outboard side of the filter cover. 2. Remove the cover. 3. Remove the air filter. 4. Install the new air filter and reverse all of the steps. Be sure the tabs of the air cleaner cover fit into the slots of the air cleaner housing. Refer to the Maintenance Schedule to determine when to replace the air filter. See “Scheduled Maintenance Services” in the Index. CAUTION: Operating the engine with the air cleaner/filter off can cause you or others to be burned. The air cleaner not only cleans the air, it stops flame if the engine backfires. If it isn’t there, and the engine backfires, you could be burned. Don’t drive with it off, and be careful working on the engine with the air cleaner/filter off. NOTICE: If the air cleaner/filter is off, a backfire can cause a damaging engine fire. And, dirt can easily get into your engine, which will damage it. Always have the air cleaner/filter in place when you’re driving. 6-21 To check or replace the air filter: 1. With the hood open, unlatch and remove the access panel. 2. To remove the filter, press on the spring tab on the side of the filter housing and pull the filter out of the housing. 3. To install the new filter, press on the spring tab and insert the filter into the housing. The filter should be fully inserted into the upper and lower grooves and locked into place by the spring tab. 4. Reinstall the air filter access panel at the base of the windshield. Passenger Compartment Air Filter The passenger compartment air filter removes certain particles from the air, including pollen and dust particles. Reductions in airflow, which may occur more often in dusty areas, indicate that the filter may need to be replaced early. The filter should be replaced as part of the routine scheduled maintenance. See “Maintenance Schedule” in the Index for more information. The passenger compartment air filter is located on the passenger side at the base of the windshield and can be accessed through a removable panel under the hood of the vehicle. See “Engine Compartment Overview” in the Index for more information on location. 6-22 Automatic Transaxle Fluid When to Check and Change A good time to check your automatic transaxle fluid level is when the engine oil is changed. Change both the fluid and filter every 50,000 miles (83 000 km) if the vehicle is mainly driven under one or more of these conditions: D In heavy city traffic where the outside temperature regularly reaches 90_F (32_C) or higher. D In hilly or mountainous terrain. D When doing frequent trailer towing. D Uses such as found in taxi, police or delivery service. If you do not use your vehicle under any of these conditions, change the fluid and filter at 100,000 miles (166 000 km). See “Scheduled Maintenance Services” in the Index. How to Check Because this operation can be a little difficult, you may choose to have this done at the dealership service department. If you do it yourself, be sure to follow all the instructions here, or you could get a false reading on the dipstick. NOTICE: Too much or too little fluid can damage your transaxle. Too much can mean that some of the fluid could come out and fall on hot engine parts or exhaust system parts, starting a fire. Be sure to get an accurate reading if you check your transaxle fluid. 6-23 Wait at least 30 minutes before checking the transaxle fluid level if you have been driving: D When outside temperatures are above 90_F (32_C). D At high speed for quite a while. D In heavy traffic -- especially in hot weather. D While pulling a trailer. To get the right reading, the fluid should be at normal operating temperature, which is 180_F to 200_F (82_C to 93_C). Get the vehicle warmed up by driving about 15 miles (24 km) when outside temperatures are above 50_F (10_C). If it’s colder than 50_F (10_C), you may have to drive longer. Checking the Fluid Level Prepare your vehicle as follows: D Park your vehicle on a level place. Keep the engine running. D With the parking brake applied, place the shift lever in PARK (P). 6-24 D With your foot on the brake pedal, move the shift lever through each gear range, pausing for about three seconds in each range. Then, position the shift lever in PARK (P). D Let the engine run at idle for three to five minutes. Then, without shutting off the engine, follow these steps: 3.5L V6 Engine 4.0L V8 Engine See “Engine Compartment Overview” in the Index for more information on location. 1. Pull out the dipstick and wipe it with a clean rag or paper towel. 2. Push it back in all the way, wait three seconds and then pull it back out again. 3.5L V6 Engine 4.0L V8 Engine 3. Check both sides of the dipstick, and read the lower level. The fluid level must be in the cross-hatched area. 4. If the fluid level is in the acceptable range, push the dipstick back in all the way. How to Add Fluid Refer to the Maintenance Schedule to determine what kind of transaxle fluid to use. See “Recommended Fluids and Lubricants” in the Index. If the fluid level is low, add only enough of the proper fluid to bring the level into the cross-hatched area on the dipstick. 1. Pull out the dipstick. 2. Using a long-neck funnel, add enough fluid at the dipstick hole to bring it to the proper level. It doesn’t take much fluid, generally less than one pint (0.5 L). Don’t overfill. NOTICE: We recommend you use only fluid labeled DEXRONR-III, because fluid with that label is made especially for your automatic transaxle. Damage caused by fluid other than DEXRONR-III is not covered by your new vehicle warranty. 3. After adding fluid, recheck the fluid level as described under “How to Check.” 4. When the correct fluid level is obtained, push the dipstick back in all the way. 6-25 NOTICE: When adding coolant, it is important that you use only DEX-COOLR (silicate-free) coolant. If coolant other than DEX-COOL is added to the system, premature engine, heater core or radiator corrosion may result. In addition, the engine coolant will require change sooner -- at 30,000 miles (50 000 km) or 24 months, whichever occurs first. Damage caused by the use of coolant other than DEX-COOLR is not covered by your new vehicle warranty. Engine Coolant The cooling system in your vehicle is filled with DEX-COOLR engine coolant. This coolant is designed to remain in your vehicle for 5 years or 150,000 miles (240 000 km), whichever occurs first, if you add only DEX-COOLR extended life coolant. The following explains your cooling system and how to add coolant when it is low. If you have a problem with engine overheating, see “Engine Overheating” in the Index. A 50/50 mixture of clean, drinkable water and DEX-COOLR coolant will: D Give freezing protection down to -34_F (-37_C). D Give boiling protection up to 265_F (129_C). D Protect against rust and corrosion. D Help keep the proper engine temperature. D Let the warning lights and gages work as they should. 6-26 What to Use Use a mixture of one-half clean, drinkable water and one-half DEX-COOLR coolant which won’t damage aluminum parts. If you use this coolant mixture, you don’t need to add anything else. CAUTION: Adding only plain water to your cooling system can be dangerous. Plain water, or some other liquid like alcohol, can boil before the proper coolant mixture will. Your vehicle’s coolant warning system is set for the proper coolant mixture. With plain water or the wrong mixture, your engine could get too hot but you wouldn’t get the overheat warning. Your engine could catch fire and you or others could be burned. Use a 50/50 mixture of clean, drinkable water and DEX-COOLR coolant. NOTICE: If you use an improper coolant mixture, your engine could overheat and be badly damaged. The repair cost wouldn’t be covered by your warranty. Too much water in the mixture can freeze and crack the engine, radiator, heater core and other parts. If you have to add coolant more than four times a year, have your dealer check your cooling system. NOTICE: If you use the proper coolant, you don’t have to add extra inhibitors or additives which claim to improve the system. These can be harmful. 6-27 Checking Coolant CAUTION: Turning the surge tank pressure cap when the engine and radiator are hot can allow steam and scalding liquids to blow out and burn you badly. Never turn the surge tank pressure cap -- even a little -- when the engine and radiator are hot. The vehicle must be on a level surface. When your engine is cold, the coolant level should be at the base of the filler neck. The engine coolant surge tank is located on the passenger’s side of the engine compartment. See “Engine Compartment Overview” in the Index for more information on location. 6-28 Adding Coolant If you need more coolant, add the proper DEX-COOLR coolant mixture at the surge tank, but only when the engine is cool. CAUTION: You can be burned if you spill coolant on hot engine parts. Coolant contains ethylene glycol, and it will burn if the engine parts are hot enough. Don’t spill coolant on a hot engine. If the LOW ENGINE COOLANT DIC message comes on and stays on, it means you’re low on engine coolant. When replacing the pressure cap, make sure it is hand-tight. 6-29 Cooling System Pressure Cap The cooling system pressure cap is located on the surge tank. NOTICE: Your cooling system pressure cap is a 15 psi (105 kPa) pressure-type cap and must be tightly installed to prevent coolant loss and possible engine damage from overheating. Power Steering Fluid When to Check Power Steering Fluid It is not necessary to regularly check power steering fluid unless you suspect there is a leak in the system or you hear an unusual noise. A fluid loss in this system could indicate a problem. Have the system inspected and repaired. See “Engine Compartment Overview” in the Index for more information on location. How to Check Power Steering Fluid Turn the key off, let the engine compartment cool down, wipe the cap and the top of the reservoir clean, then unscrew the cap and wipe the dipstick with a clean rag. Replace the cap and completely tighten it. Then remove the cap again and look at the fluid level on the dipstick. The level should be at the FULL COLD mark. If necessary, add only enough fluid to bring the level up to the mark. What to Use To determine what kind of fluid to use, see “Recommended Fluids and Lubricants” in the Index. Always use the proper fluid. Failure to use the proper fluid can cause leaks and damage hoses and seals. 6-30 Windshield Washer Fluid What to Use When you need windshield washer fluid, be sure to read the manufacturer’s instructions before use. If you will be operating your vehicle in an area where the temperature may fall below freezing, use a fluid that has sufficient protection against freezing. Adding Washer Fluid The windshield washer fluid reservoir is located at the front of the engine compartment on the passenger’s side. See “Engine Compartment Overview” in the Index for more information on location. When the tank contains 0.5 quarts (0.5 liters) or less, the message LOW WASHER FLUID will be displayed on the Driver Information Center (DIC). Open the cap labeled WASHER FLUID. Add washer fluid until the tank is full. NOTICE: D When using concentrated washer fluid, follow the manufacturer’s instructions for adding water. D Don’t mix water with ready-to-use washer fluid. Water can cause the solution to freeze and damage your washer fluid tank and other parts of the washer system. Also, water doesn’t clean as well as washer fluid. D Fill your washer fluid tank only three-quarters full when it’s very cold. This allows for expansion if freezing occurs, which could damage the tank if it is completely full. D Don’t use engine coolant (antifreeze) in your windshield washer. It can damage your washer system and paint. 6-31 Brakes Brake Fluid See “Engine Compartment Overview” in the Index for more information on location. Your brake master cylinder reservoir is on the driver’s side of the engine compartment. It is filled with DOT-3 brake fluid. There are only two reasons why the brake fluid level in the reservoir might go down. The first is that the brake fluid goes down to an acceptable level during normal brake lining wear. When new linings are put in, the fluid level goes back up. The other reason is that fluid is leaking out of the brake system. If it is, you should have your brake system fixed, since a leak means that sooner or later your brakes won’t work well, or won’t work at all. 6-32 So, it isn’t a good idea to “top off” your brake fluid. Adding brake fluid won’t correct a leak. If you add fluid when your linings are worn, then you’ll have too much fluid when you get new brake linings. You should add (or remove) brake fluid, as necessary, only when work is done on the brake hydraulic system. CAUTION: If you have too much brake fluid, it can spill on the engine. The fluid will burn if the engine is hot enough. You or others could be burned, and your vehicle could be damaged. Add brake fluid only when work is done on the brake hydraulic system. When your brake fluid falls to a low level, your brake warning light will come on. A chime will sound if you try to drive with this warning light on. See “Brake System Warning Light” in the Index. What to Add When you do need brake fluid, use only DOT-3 brake fluid. Use new brake fluid from a sealed container only. Refer to “Recommended Fluids and Lubricants” in the Maintenance Schedule. Always clean the brake fluid reservoir cap and the area around the cap before removing it. This will help keep dirt from entering the reservoir. CAUTION: With the wrong kind of fluid in your brake system, your brakes may not work well, or they may not even work at all. This could cause a crash. Always use the proper brake fluid. NOTICE: D Using the wrong fluid can badly damage brake system parts. For example, just a few drops of mineral-based oil, such as engine oil, in your brake system can damage brake system parts so badly that they’ll have to be replaced. Don’t let someone put in the wrong kind of fluid. D If you spill brake fluid on your vehicle’s painted surfaces, the paint finish can be damaged. Be careful not to spill brake fluid on your vehicle. If you do, wash it off immediately. See “Appearance Care” in the Index. 6-33 Brake Wear Your vehicle has four-wheel disc brakes. Disc brake pads have built-in wear indicators that make a high-pitched warning sound when the brake pads are worn and new pads are needed. The sound may come and go or be heard all the time your vehicle is moving (except when you are pushing on the brake pedal firmly). CAUTION: The brake wear warning sound means that soon your brakes won’t work well. That could lead to an accident. When you hear the brake wear warning sound, have your vehicle serviced. NOTICE: Continuing to drive with worn-out brake pads could result in costly brake repair. Some driving conditions or climates may cause a brake squeal when the brakes are first applied or lightly applied. This does not mean something is wrong with your brakes. Properly torqued wheel nuts are necessary to help prevent brake pulsation. When tires are rotated, inspect brake pads for wear and evenly tighten wheel nuts in the proper sequence to GM torque specifications. Brake linings should always be replaced as complete axle sets. See “Brake System Inspection” in Section 7 of this manual under Part C “Periodic Maintenance Inspections.” Brake Pedal Travel See your dealer if the brake pedal does not return to normal height, or if there is a rapid increase in pedal travel. This could be a sign of brake trouble. Brake Adjustment Every time you apply the brakes, with or without the vehicle moving, your brakes adjust for wear. 6-34 Replacing Brake System Parts The braking system on a vehicle is complex. Its many parts have to be of top quality and work well together if the vehicle is to have really good braking. Your vehicle was designed and tested with top-quality GM brake parts. When you replace parts of your braking system -- for example, when your brake linings wear down and you have to have new ones put in -- be sure you get new approved GM replacement parts. If you don’t, your brakes may no longer work properly. For example, if someone puts in brake linings that are wrong for your vehicle, the balance between your front and rear brakes can change -- for the worse. The braking performance you’ve come to expect can change in many other ways if someone puts in the wrong replacement brake parts. Battery Your new vehicle comes with a maintenance free ACDelcoR battery. When it’s time for a new battery, get one that has the replacement number shown on the original battery’s label. We recommend an ACDelco battery. The battery is located under the rear seat cushion. To access the battery, see “Removing the Rear Seat Cushion” in the Index. You don’t need to access the battery to jump start your vehicle. See “Jump Starting” in the Index. CAUTION: A battery that isn’t properly vented can let sulfuric acid fumes into the area under the rear seat cushion. These fumes can damage your rear seat safety belt systems. You may not be able to see this damage, and the safety belts might not provide the protection needed in a crash. If a replacement battery is ever needed, it must be vented in the same manner as the original battery. Always make sure that the vent hose is properly reattached before reinstalling the seat cushion. 6-35 Vehicle Storage If you’re not going to drive your vehicle for 25 days or more, remove the black, negative (-) cable from the battery. This will help keep your battery from running down. CAUTION: Batteries have acid that can burn you and gas that can explode. You can be badly hurt if you aren’t careful. See “Jump Starting” in the Index for tips on working around a battery without getting hurt. Contact your dealer to learn how to prepare your vehicle for longer storage periods. Also, for your audio system, see “Theft-Deterrent Feature” in the Index. To be sure the vent hose (A) is properly attached, the vent hose connectors (B) must be securely reattached to the vent outlets (C) on each side of the battery, and the vent assembly grommet (D) must be secured to the floor pan (E). 6-36 Bulb Replacement This section describes bulb changing procedures for some of your interior and exterior lamps. For any bulb changing procedure not listed in this section, contact your dealer’s service department. For the type of bulb to use, see “Replacement Bulbs” in the Index. Halogen Bulbs CAUTION: Halogen bulbs have pressurized gas inside and can burst if you drop or scratch the bulb. You or others could be injured. Be sure to read and follow the instructions on the bulb package. Headlamps For the proper bulb type, see “Replacement Bulbs” in the Index. 1. Remove the two bolts with a 10 mm socket. 2. Use a large screwdriver by the outside mount to separate the lamp assembly from the outboard snap mounting pin. Slide the headlamp assembly outward and lift it out. 6-37 3. Disconnect the wiring harness from the headlamp assembly. 4. Lift the tabs to remove the bulb from the assembly. 5. Replace the bulb. Push the bulb assembly in and turn it clockwise to install the bulb assembly into the headlamp assembly. Then reconnect the wiring harness to the lamp assembly. 6-38 Headlamp Aiming Your vehicle has a visual optical headlamp aiming system equipped with horizontal aim indicators. The aim has been pre-set at the factory and should need no further adjustment. This is true even though your horizontal aim indicators may not fall exactly on the “0” (zero) marks on their scales. 6. Slide the lamp assembly back into place by lining up the track on the bottom of the assembly with the guide on the vehicle. Then connect the outboard snap and secure the lamp assembly with the two bolts. 6-39 If your vehicle is damaged in an accident, the headlamp aim may be affected. Aim adjustment to the low beam may be necessary if it is difficult to see lane markers (for horizontal aim), or if oncoming drivers flash their high beams at you (for vertical aim). If you believe your headlamps need to be re-aimed, we recommend that you take your vehicle to your dealer for service. However, it is possible for you to re-aim your headlamps as described in the following procedure. NOTICE: To make sure your headlamps are aimed properly, read all the instructions before beginning. Failure to follow these instructions could cause damage to headlamp parts. The vehicle should be properly prepared as follows: D The vehicle should be placed so the headlamps are 25 ft. (7.6 m) from a light colored wall or other flat surface. D The vehicle must have all four tires on a perfectly level surface which is level all the way to the wall or other flat surface. D The vehicle should be placed so it is perpendicular to the wall or other flat surface. D The vehicle should not have any snow, ice or mud attached to it. D The vehicle should be fully assembled and all other work stopped while headlamp aiming is being done. D The vehicle should be normally loaded with a full tank of fuel and one person or 160 lbs. (75 kg) on the driver’s seat. D Tires should be properly inflated. Headlamp aiming is done with the vehicle low beam lamps. The high beam lamps will be correctly aimed if the low beam lamps are aimed properly. The headlamp aiming devices are under the hood near the headlamps. 6-40 If you believe your headlamps need horizontal (left/right) adjustment, follow the horizontal aiming procedure. If you believe your headlamps need only vertical (up/down) adjustment, follow only the vertical aiming procedure. Adjustment screws can be turned with an E8 TorxR socket or T15 Torx screwdriver. Headlamp Horizontal Aiming Turn the horizontal aiming screw (A) until the indicator (B) is lined up with zero. Once the horizontal aim is adjusted, then adjust the vertical aim. 6-41 Headlamp Vertical Aiming 1. Find the aim dot on the lens of the lamps. 3. At the wall or other flat surface, measure from the floor to the recorded distance and draw a horizontal line the width of the vehicle. 2. Measure the distance from the ground to the aim dot on each lamp; if left low beam, subtract two inches. Record this distance. 6-42 4. Turn on the low beam headlamps and cover the lamp not being evaluated. The ambient light should allow the beam cut off to be seen on the wall. 5. Turn the vertical aiming screw (C) until the headlamp beam is aimed to the horizontal line. It is recommended to cover the lamp that is not being evaluated to better see the beam being aimed. 6-43 Front Turn Signals and Parking Lamps 1. Remove the two bolts with a 10 mm socket. 2. Use a large screwdriver by the outside mount to separate the lamp assembly from the outboard snap mounting pin. Slide the headlamp assembly outward and lift it out. 3. Disconnect the wiring harness from the headlamp assembly. 6-44 4. Tip the headlamp assembly and while pressing the release, turn the bulb and socket counterclockwise to remove them. 5. Replace the bulb and socket. Then reconnect the wiring harness to the lamp assembly. 6. Slide the lamp assembly back into place by lining up the track on the bottom of the assembly with the guide on the vehicle. Then connect the outboard snap and secure the lamp assembly with the two bolts. 6-45 Rear Turn Signals, Stoplamps, Taillamps and Back-up Lamps For the proper bulb type, see “Replacement Bulbs” in the Index. 1. Open the trunk. Turn the screws located inside of the trunk counterclockwise and remove them. 2. Remove the plastic trim piece from the trunk. 3. Pull the carpeting away from the rear corner of the trunk. 6-46 4. Remove the three 10 mm nuts holding the lamp in place and remove the lamp assembly. 5. While pressing the release, turn the bulb socket assembly counterclockwise to remove it from the lamp assembly. 6. Pull the bulb straight out to remove it from the socket. 7. Replace the bulb and reverse the steps to reinstall the lamp assembly. Windshield Wiper Blade Replacement Windshield wiper blades should be inspected at least twice a year for wear or cracking. See “Wiper Blade Check” in the Index for more information. To replace the wiper blade assembly: 1. Lift the wiper arm up from the windshield and set it in the vertically locked position. 2. Push the tab on the wiper blade assembly and pull the assembly down enough to release it from the “U” hooked end of the wiper arm. Slide the assembly away from the arm. 3. Remove the blade. 4. To reinstall the wiper blade assembly, slide it over the wiper arm to engage the “U” hooked end on the wiper blade assembly. Pull up on the assembly to lock it into place. For the proper windshield wiper blade replacement length and type, see “Normal Maintenance Replacement Parts” in the Index. 6-47 Tires Your new vehicle comes with high-quality tires made by a leading tire manufacturer. If you ever have questions about your tire warranty and where to obtain service, see your Oldsmobile Warranty booklet for details. CAUTION: Poorly maintained and improperly used tires are dangerous. D Overloading your tires can cause overheating as a result of too much friction. You could have an air-out and a serious accident. See “Loading Your Vehicle” in the Index. CAUTION: (Continued) CAUTION: (Continued) D Underinflated tires pose the same danger as overloaded tires. The resulting accident could cause serious injury. Check all tires frequently to maintain the recommended pressure. Tire pressure should be checked when your tires are cold. D Overinflated tires are more likely to be cut, punctured or broken by a sudden impact -- such as when you hit a pothole. Keep tires at the recommended pressure. D Worn, old tires can cause accidents. If your tread is badly worn, or if your tires have been damaged, replace them. 6-48 Inflation -- Tire Pressure The Tire-Loading Information label, which is on the rear edge of the driver’s door, shows the correct inflation pressures for your tires when they’re cold. “Cold” means your vehicle has been sitting for at least three hours or driven no more than 1 mile (1.6 km). NOTICE: Don’t let anyone tell you that underinflation or overinflation is all right. It’s not. If your tires don’t have enough air (underinflation), you can get the following: D Too much flexing D Too much heat D Tire overloading D Bad wear D Bad handling D Bad fuel economy. NOTICE: (Continued) NOTICE: (Continued) If your tires have too much air (overinflation), you can get the following: D Unusual wear D Bad handling D Rough ride D Needless damage from road hazards. When to Check Check your tires once a month or more. Don’t forget your compact spare tire. It should be at 60 psi (420 kPa). How to Check Use a good quality pocket-type gage to check tire pressure. You can’t tell if your tires are properly inflated simply by looking at them. Radial tires may look properly inflated even when they’re underinflated. Be sure to put the valve caps back on the valve stems. They help prevent leaks by keeping out dirt and moisture. 6-49 Check Tire Pressure System The check tire pressure system can alert you to a large change in the pressure of one tire. The system won’t alert you before you drive that a tire is low or flat. You must begin driving before the system will work properly. The LOW TIRE PRESSURE message will appear on the Driver Information Center (DIC) if pressure difference (low pressure) is detected in one tire. The check tire pressure system may not alert you if: D more than one tire is low, D the vehicle is moving faster than 65 mph (105 km/h), D the system is not yet calibrated, D the tire treadwear is uneven, D the compact spare tire is installed, D tire chains are being used, or D the vehicle is being driven on a rough or frozen road. If the anti-lock brake system warning light comes on, the check tire pressure system may not be working properly. See your dealer for service. Also, see “Anti-Lock Brake System Warning Light” in the Index. The check tire pressure system detects differences in tire rotation speeds that are caused by changes in tire pressure. The system can alert you about a low tire -- but it doesn’t replace normal tire maintenance. See “Tires” in the Index. When the LOW TIRE PRESSURE message appears on the Driver Information Center, you should stop as soon as you can and check all your tires for damage. If a tire is flat, see “If a Tire Goes Flat” in the Index. Also check the tire pressure in all four tires as soon as you can. See “Inflation-Tire Pressure” in the Index. Any time you adjust a tire’s pressure or have one or more tires repaired or replaced, you’ll need to reset (calibrate) the check tire pressure system. You’ll also need to reset the system whenever you rotate the tires, buy new tires, install or remove the compact spare, and whenever the vehicle’s battery has been disconnected. Don’t reset the check tire pressure system without first correcting the cause of the problem and checking and adjusting the pressure in all four tires. If you reset the system when the tire pressures are incorrect, the check tire pressure system will not work properly and may not alert you when a tire is low or high. 6-50 To reset (calibrate) the system: 1. Turn the ignition switch to RUN. 2. Press the SELECT right arrow button on the DIC until you enter the GAGE mode. Then press the SELECT down arrow until TIRE PRESSURE appears on the display. 3. Press and hold the DIC RESET button for about five seconds. After five seconds, the display will show TIRE PRESSURE RESET. If TIRE PRESSURE RESET does not appear on the display after about five seconds, see your dealer for service. After you release the DIC RESET button, TIRE PRESSURE NORMAL will appear on the display. The system completes the calibration process during driving. Calibration time can take 45 to 90 minutes, depending on your driving habits. After the system has been calibrated, the system will alert the driver that a tire is low, up to a maximum speed of 65 mph (105 km/h). Tire Inspection and Rotation Tires should be rotated every 6,000 to 8,000 miles (10 000 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’s Time for New Tires” and “Wheel Replacement” later in this section 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 Services” in the Index for scheduled rotation intervals. When rotating your tires, always use the correct rotation pattern shown here. 6-51 Don’t include the compact spare tire in your tire rotation. After the tires have been rotated, adjust the front and rear inflation pressures as shown on the Tire-Loading Information label. Reset the Check Tire Pressure System. See “Check Tire Pressure System” in the Index. Make certain that all wheel nuts are properly tightened. See “Wheel Nut Torque” in the Index. CAUTION:
