Fuel Use of the recommended fuel is an important part of the proper maintenance of your vehicle. Gasoline Octane Use regular unleaded gasoline with a posted octane of 87 or higher. If the octane is less than 87, you may get a heavy knocking noise when you drive. If this occurs, use a gasoline rated at 87 octane or higher as soon as possible. Otherwise, you might damage your engine. A little pinging noise when you accelerate or drive uphill is considered normal. This does not indicate a problem exists or that a higher-octane fuel is necessary. If you are using 87 octane or higher-octane fuel and hear heavy knocking, your engine needs service. Gasoline Speciﬁcations It is recommended that gasoline meet speciﬁcations which were developed by automobile manufacturers around the world and contained in the World-Wide Fuel Charter which is available from the Alliance of Automobile Manufacturers at www.autoalliance.org/fuel_charter.htm. Gasoline meeting these speciﬁcations could provide improved driveability and emission control system performance compared to other gasoline. California Fuel If your vehicle is certiﬁed to meet California Emission Standards, it is designed to operate on fuels that meet California speciﬁcations. See the underhood emission control label. If this fuel is 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 may turn on and your vehicle may fail a smog-check test. See Malfunction Indicator Lamp on page 3-30. If this occurs, return to your authorized GM dealer for diagnosis. If it is determined that the condition is caused by the type of fuel used, repairs may not be covered by your warranty. 5-5 Some gasolines that are not reformulated for low emissions may contain an octane-enhancing additive called methylcyclopentadienyl manganese tricarbonyl (MMT); ask the attendant where you buy gasoline whether the fuel contains MMT. General Motors does not recommend the use of such gasolines. Fuels containing MMT can reduce the life of spark plugs and the performance of the emission control system may be affected. The malfunction indicator lamp may turn on. If this occurs, return to your authorized GM dealer for service. 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 would not be covered by your warranty. To check the fuel availability, ask an auto club, or contact a major oil company that does business in the country where you will be driving. Additives To provide cleaner air, all gasolines in the United States are now required to contain additives that will help prevent engine and fuel system deposits from forming, allowing your emission control system to work properly. In most cases, you should not have to add anything to your fuel. However, some gasolines contain only the minimum amount of additive required to meet U.S. Environmental Protection Agency regulations. General Motors recommends that you buy gasolines that are advertised to help keep fuel injectors and intake valves clean. If your vehicle experiences problems due to dirty injectors or valves, try a different brand of gasoline. Also, your GM dealer has additives that will help correct and prevent most deposit-related problems. 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. Do not use fuel containing methanol. It can corrode metal parts in your fuel system and also damage the plastic and rubber parts. That damage would not be covered under your warranty. 5-6 Filling Your Tank {CAUTION: Fuel vapor burns violently and a fuel ﬁre can cause bad injuries. To help avoid injuries to you and others, read and follow all the instructions on the pump island. Turn off your engine when you are refueling. Do not smoke if you are near fuel or refueling your vehicle. Keep sparks, ﬂames and smoking materials away from fuel. Do not leave the fuel pump unattended when refueling your vehicle — this is against the law in some places. Keep children away from the fuel pump; never let children pump fuel. To open the fuel ﬁller door, pull up on the release lever located on the ﬂoor on the outboard side of the driver’s seat. 5-7 {CAUTION: If you spill fuel and then something ignites it, you could be badly burned. Fuel can spray out on you if you open the fuel cap too quickly. This spray can happen if your tank is nearly full, and is more likely in hot weather. Open the fuel cap slowly and wait for any hiss noise to stop. Then unscrew the cap all the way. Be careful not to spill fuel. Do not top off or overﬁll the tank and wait a few seconds after you have ﬁnished pumping before removing the nozzle. Clean fuel from painted surfaces as soon as possible. See Washing Your Vehicle on page 5-74. When replacing the fuel cap, turn it to the right (clockwise) until it clicks. Make sure the cap is fully installed. 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 on page 3-30. The tethered fuel cap is located behind a hinged fuel door on the passenger’s side of the vehicle. To remove the fuel cap, turn it slowly to the left (counterclockwise). The fuel cap has a spring in it; if the cap is released too soon, it will spring back to the right. 5-8 {CAUTION: If a ﬁre starts while you are refueling, do not remove the nozzle. Shut off the ﬂow of fuel by shutting off the pump or by notifying the station attendant. Leave the area immediately. If you need a new fuel cap, be sure to get Notice: 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 may damage your fuel tank and emissions system. See Malfunction Indicator Lamp on page 3-30. Filling a Portable Fuel Container {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: (cid:127) Dispense gasoline only into approved containers. (cid:127) 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. (cid:127) 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. (cid:127) Do not smoke while pumping gasoline. 5-9 Checking Things Under the Hood Hood Release To open the hood, do the following: 1. Pull the hood release handle inside the vehicle. It is located on the lower left side of the instrument panel. {CAUTION: 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 fuel, 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. 5-10 2. Then go to the front of the vehicle and lift up on the secondary hood release lever, located under the front center of the hood. 3. Lift the hood and release the hood prop from its retainer located on the underside of the hood. Before closing the hood, be sure all the ﬁller caps are on properly. Then lift the hood to relieve pressure on the hood prop. Remove the hood prop from the slot in the inner fender and return the prop to its retainer. Lower the hood 12 inches (30 cm) above the vehicle and release it to latch fully. Check to make sure the hood is closed and repeat the process if necessary. 4. Place the hood prop into the slot on the inner fender. 5-11 Engine Compartment Overview When you open the hood, here is what you will see: Automatic shown, Manual similar 5-12 A.

See “Adding Washer Fluid” under Windshield Washer Fluid on page 5-32. Engine Oil If the oil pressure light appears on the instrument cluster, it means you need to check your engine oil level right away. For more information, see Oil Pressure Light on page 3-33. You should check your engine oil level regularly; this is an added reminder. Checking Engine Oil It is 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 engine oil dipstick handle is a yellow loop. See Engine Compartment Overview on page 5-12 for the location of the engine oil dipstick. 1. Turn off the engine and give the oil several minutes to drain back into the oil pan. If you do not do this, the oil dipstick might not show the actual level. 2. Pull 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. 5-13 When to Add Engine Oil What Kind of Engine Oil to Use If the oil is at or below the lower hole at the tip of the dipstick (B), then you will need to add at least one quart of oil. But you must use the right kind. This section explains what kind of oil to use. For engine oil crankcase capacity, see Capacities and Speciﬁcations on page 5-85. Notice: Do not add too much oil. If your engine has so much oil that the oil level gets above the upper hole (A) that shows the proper operating range, your engine could be damaged. See Engine Compartment Overview on page 5-12 for the location of the engine oil ﬁll cap. Be sure to add enough oil to put the level somewhere in the proper operating range, between the holes on the dipstick. Push the dipstick all the way back in when you are through. 5-14 Look for two things: • GM6094M Your vehicle’s engine requires oil meeting GM Standard GM6094M. You should look for and use only an oil that meets GM Standard GM6094M. • SAE 5W-30 As shown in the viscosity chart, SAE 5W-30 is best for your vehicle. These numbers on an oil container show its viscosity, or thickness. Do not use other viscosity oils such as SAE 20W-50. Oils meeting these requirements should also have the starburst symbol on the container. This symbol indicates that the oil has been certiﬁed by the American Petroleum Institute (API). You should look for this information on the oil container, and use only those oils that are identiﬁed as meeting GM Standard GM6094M and have the starburst symbol on the front of the oil container. Notice: Use only engine oil identiﬁed as meeting GM Standard GM6094M and showing 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 Goodwrench® oil meets all the requirements for your vehicle. If you are in an area of extreme cold, where the temperature falls below −20°F (−29°C), it is recommended that you use 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. Engine Oil Additives Do not add anything to your oil. The recommended oils with the starburst symbol that meet GM Standard GM6094M are all you will need for good performance and engine protection. 5-15 What to Do with Used Oil Used engine oil contains certain elements that may be unhealthy for your skin and could even cause cancer. Do not 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 dispose of 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 threat to the environment. If you change your own oil, be sure to drain all the oil from the ﬁlter before disposal. Never 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. When to Change Engine Oil If any one of these is true for you, use the short trip/city maintenance schedule: • Most trips are less than 5 miles (8 km). This is particularly important when outside temperatures are below freezing. • Most trips include extensive idling, such as frequent driving in stop-and-go traffic. • You frequently tow a trailer or use a carrier on top of your vehicle. • The vehicle is used for delivery service, police, taxi, or other commercial application. Driving under these conditions causes engine oil to break down sooner. If any one of these is true for your vehicle, then you need to change your oil and ﬁlter every 3,000 miles (5 000 km) or 3 months — whichever occurs ﬁrst. If none of them is true, use the long trip/highway maintenance schedule. Change oil and ﬁlter every 7,500 miles (12 500 km) or 12 months — whichever occurs ﬁrst. Driving a vehicle with a fully warmed engine under highway conditions will cause engine oil to break down slower. 5-16 Engine Air Cleaner/Filter The engine air cleaner/ﬁlter is located in the engine compartment on the passenger’s side of the vehicle. See Engine Compartment Overview on page 5-12 for more information on location. When to Inspect the Engine Air Cleaner/Filter Inspect the engine air cleaner/ﬁlter every 15,000 miles (25 000 km) and replace every 30,000 miles (50 000 km). If you are driving in dusty/dirty conditions, inspect the ﬁlter at each engine oil change. How to Inspect the Engine Air Cleaner/Filter To inspect the engine air cleaner/ﬁlter remove the ﬁlter from the vehicle and lightly shake the ﬁlter to release loose dust and dirt. If the ﬁlter remains caked with dirt, a new ﬁlter is required. 5-17 Automatic Transaxle Fluid When to Check Check your automatic transaxle ﬂuid level at least twice a year. Add ﬂuid if needed. See At Least Twice a Year on page 6-18. 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 the transaxle. Too much can mean that some of the ﬂuid could come out and fall on hot engine or exhaust system parts, starting a ﬁre. Too little ﬂuid could cause the transaxle to overheat. Be sure to get an accurate reading if you check the transaxle ﬂuid. To inspect or replace the ﬁlter, do the following: 1. Remove the screws and lift off the cover. 2. Inspect or replace the engine air cleaner/ﬁlter. 3. Put the cover back on tightly and tighten the screws. See Using Your Maintenance Schedule on page 6-4 for replacement intervals. {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 helps to stop ﬂame if the engine backﬁres. If it is not there and the engine backﬁres, you could be burned. Do not drive with it off, and be careful working on the engine with the air cleaner/ﬁlter off. If the air cleaner/ﬁlter is off, a backﬁre Notice: 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 are driving. 5-18 Wait at least 30 minutes before checking the transaxle ﬂuid level if you have been driving: • When outside temperatures are above 90°F (32°C). • At high speed for quite a while. • In heavy traffic — especially in hot weather. To get the right reading, the ﬂuid should be at normal operating temperature, which is 158°F to 176°F (70°C to 80°C). Get the vehicle warmed up by driving about 15 miles (24 km) when outside temperatures are above 50°F (10°C). If it is colder than 50°F (10°C), you may have to drive longer. Checking the Fluid Level Prepare your vehicle as follows: • Park your vehicle on a level place. Keep the engine running. • With the parking brake applied, place the shift lever in PARK (P). • 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). • Let the engine run at idle for three to ﬁve minutes. Then, without shutting off the engine, follow these steps: The automatic transaxle dipstick is located toward the front of the engine compartment, near the power steering ﬂuid reservoir. See Engine Compartment Overview on page 5-12 for more information on location. 1. Pull out the dipstick and wipe it with a clean rag or paper towel. 2. Push the dipstick back in all the way, wait three seconds and then pull it back out again. 3. Check both sides of the dipstick, and read the lower level. The ﬂuid level must be between the two dimples in the hot range. 4. If the ﬂuid level is in the acceptable range, push the dipstick back in all the way. 5-19 How to Add Fluid Refer to the Maintenance Schedule to determine what kind of transaxle ﬂuid to use. See Part D: Recommended Fluids and Lubricants on page 6-24. If the ﬂuid level is low, add only enough of the proper ﬂuid to bring the level into the area between the two dimples in the hot range 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 does not take much ﬂuid, generally less than one pint (0.5 L). Do not overﬁll. Notice: Use of automatic transaxle ﬂuid labeled other than T-IV Automatic Transaxle Fluid may damage your vehicle, and the damages may not be covered by your warranty. Always use T-IV labeled automatic transaxle ﬂuid in your vehicle. See Part D: Recommended Fluids and Lubricants on page 6-24 for more information. 3. After adding ﬂuid, recheck the ﬂuid level as described under “How to Check,” earlier in this section. 4. When the correct ﬂuid level is obtained, push the dipstick back in all the way. 5-20 Manual Transaxle Fluid It is not necessary to check the transaxle ﬂuid level. A transaxle ﬂuid leak is the only reason for ﬂuid loss. If a leak occurs, take the vehicle to the dealership service department and have it repaired as soon as possible. See Part D: Recommended Fluids and Lubricants on page 6-24 for the proper ﬂuid to use. Hydraulic Clutch There is one reservoir for both the brake and the hydraulic clutch ﬂuid. See Brakes on page 5-33 for more information. The hydraulic clutch linkage in your vehicle is self-adjusting. The master cylinder reservoir is ﬁlled with hydraulic ﬂuid. A ﬂuid loss in this system could indicate a problem. Have the system inspected and repaired. When to Check and What to Use Refer to the Maintenance Schedule to determine how often you should check the ﬂuid level in your master cylinder reservoir and for the proper ﬂuid. See Part B: Owner Checks and Services on page 6-18 and Part D: Recommended Fluids and Lubricants on page 6-24. How to Check and Add Fluid To check the ﬂuid level, look on the side of the reservoir. If the ﬂuid reaches the MAX (A) mark on the reservoir, the ﬂuid level is correct. The reservoir is located near the back of the engine compartment on the driver’s side of the vehicle. See Engine Compartment Overview on page 5-12 for more information on location. Engine 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 on page 5-24. A 50/50 mixture of clean, drinkable water and proper coolant will: • Give freezing protection down to −22°F (−30°C). • Give boiling protection up to 268°F (131°C). • Protect against rust and corrosion. • Help keep the proper engine temperature. • Let the warning lights and gages work as they should. 5-21 If you use an improper coolant mixture, Notice: your engine could overheat and be badly damaged. The repair cost would not 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: have to add extra inhibitors or additives which claim to improve the system. These can be harmful. If you use the proper coolant, you do not What to Use Use a 50/50 mixture of clean, drinkable water and coolant that meets GM Speciﬁcation 1825M, which will not damage aluminum parts. You can also use a recycled coolant conforming to GM Speciﬁcation 1825M with a complete coolant ﬂush and reﬁll. If you use this coolant mixture, you do not need to add anything else. {CAUTION: Adding only plain water to your cooling system can be dangerous. Plain water, or some other liquid such as 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 would not 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 the proper coolant. 5-22 Checking Coolant The engine coolant surge tank is located in the rear of the engine compartment on the driver’s side of the vehicle. See Engine Compartment Overview on page 5-12 for more information on location. {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 between the MAX (A) and MIN (B) marks on the coolant surge tank. The level rises at engine operation temperature and drops again when the engine cools down. 5-23 Adding Coolant If the level falls below the MIN (B) mark, add the proper coolant mixture at the surge tank, but only when the engine is cool. If the surge tank is empty, a special ﬁll procedure is necessary. See Cooling System on page 5-26 for instructions on “How to Add Coolant to the Coolant Surge Tank.” Engine Overheating You will ﬁnd a coolant temperature gage on your vehicle’s instrument panel cluster. See Engine Coolant Temperature Gage on page 3-23. If Steam Is Coming From Your Engine {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. Do not spill coolant on a hot engine. When replacing the pressure cap, make sure it is hand-tight. Coolant Surge Tank Pressure Cap Notice: If the pressure cap is not tightly installed, coolant loss and possible engine damage may occur. Be sure the cap is properly and tightly secured. 5-24 {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. If you no longer have the overheat warning, you can drive. Just to be safe, drive slower for about 10 minutes. If the warning does not come back on, you can drive normally. If the warning continues and you have not stopped, pull over, stop, and park your vehicle right away. If there is still no sign of steam, you can idle the engine for three minutes while you are parked. If you still have the warning, turn off the engine and get everyone out of the vehicle until it cools down. You may decide not to lift the hood, but to get service help right away. If your engine catches ﬁre because you Notice: keep driving with no coolant, your vehicle can be badly damaged. The costly repairs would not be covered by your warranty. 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: • Climb a long hill on a hot day. • Stop after high-speed driving. • Idle for long periods in traffic. If you get the overheat warning with no sign of steam, try this for a minute or so: 1. In heavy traffic, let the engine idle in NEUTRAL (N) while stopped. If it is safe to do so, pull off the road, shift to PARK (P) or NEUTRAL (N) and let the engine idle. 2. Turn on your heater to full hot at the highest fan speed and open the windows as necessary. 5-25 Cooling System When you decide it is safe to lift the hood, here is what you will 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, do not do anything else until it cools down. The vehicle should be parked on a level surface. Make sure that the air conditioning is turned off. The coolant level should be between the MIN and MAX marks on the coolant surge tank when the engine is cool. If it is not, you may have a leak at the pressure cap or in the radiator hoses, heater hoses, radiator, water pump or somewhere else in the cooling system. A. Coolant Surge Tank with Pressure Cap B. Electric Engine Cooling Fan 5-26 {CAUTION: Heater and radiator hoses, and other engine parts, can be very hot. Do not touch them. If you do, you can be burned. Do not 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. If there seems to be no leak, with the engine on, check to see if the electric engine cooling fan is running. If the engine is overheating, the fan should be running. If it is not, your vehicle needs service. Notice: Engine damage from running your engine without coolant is not covered by your warranty. How to Add Coolant to the Coolant Surge Tank Notice: This vehicle has a speciﬁc coolant ﬁll procedure. Failure to follow this procedure could cause your engine to overheat and be severely damaged. If you have not found a problem yet, check to see if coolant is visible in the surge tank. If coolant is visible but the coolant level is not between the MIN and MAX marks, add a 50/50 mixture of clean, drinkable water and proper 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 on page 5-21 for more information. 5-27 If no coolant is visible in the surge tank, add coolant as follows: {CAUTION: {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 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. Adding only plain water to your cooling system can be dangerous. Plain water, or some other liquid such as 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 would not 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 a proper coolant. In cold weather, water can freeze and crack Notice: the engine, radiator, heater core and other parts. Use the recommended coolant and the proper coolant mixture. 5-28 {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. Do not spill coolant on a hot engine. 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 two or two and one-half turns. If you hear a hiss, wait for that to stop. This will allow any pressure still left to be vented out the discharge hose. 2. Then keep turning the pressure cap slowly, and remove it. 5-29 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 fan. By this time, the coolant level inside the coolant surge tank may be lower. If the level is lower than the MAX mark, add more of the proper mixture to the coolant surge tank until the level reaches the MAX mark. 5. Then replace the pressure cap. Be sure the pressure cap is hand-tight and fully seated. See your dealer, if necessary. 3. Fill the coolant surge tank with the proper mixture to the MAX mark on the coolant surge tank. Wait about ﬁve minutes, then check to see if the level is below the MAX mark. If the level is below the MAX mark, add additional coolant to bring the level up to the MAX mark. Repeat this procedure until the level remains constant at the MAX mark for at least ﬁve minutes. 5-30 Power Steering Fluid When to Check Power Steering Fluid The power steering ﬂuid reservoir is located toward the front of the engine compartment on the driver’s side of the vehicle. See Engine Compartment Overview on page 5-12 for reservoir location. 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. How to Check Power Steering Fluid Turn the key off and let the engine compartment cool down. The level should be between the MIN (B) and MAX (A) marks on the reservoir. If the level drops below the MIN (B) mark, add power steering ﬂuid. What to Use To determine what kind of ﬂuid to use, see Part D: Recommended Fluids and Lubricants on page 6-24. Always use the proper ﬂuid. Failure to use the proper ﬂuid can cause leaks and damage hoses and seals. 5-31 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 Open the cap with the washer symbol on it. Add washer ﬂuid until the tank is full. See Engine Compartment Overview on page 5-12 for reservoir location. Notice: (cid:127) When using concentrated washer ﬂuid, follow the manufacturer’s instructions for adding water. (cid:127) Do not 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 does not clean as well as washer ﬂuid. Fill your washer ﬂuid tank only three-quarters full when it is very cold. This allows for expansion if freezing occurs, which could damage the tank if it is completely full. (cid:127) Do not use engine coolant (antifreeze) in your windshield washer. It can damage your washer system and paint. 5-32 (cid:127) Brakes Brake Fluid Your vehicle has one reservoir for both the brake and clutch hydraulic systems. It is ﬁlled with DOT-3 brake ﬂuid. See Engine Compartment Overview on page 5-12 for the location of the reservoir. 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 or clutch system. If it is, you should have your brake/clutch system ﬁxed, since a leak means that sooner or later your brakes will not work well, or will not work at all. So, it is not a good idea to top off your brake ﬂuid. Adding brake ﬂuid will not correct a leak. If you add ﬂuid when your linings are worn, then you will 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 and/or clutch hydraulic system. When your brake ﬂuid falls to a low level, your brake warning light will come on. See Brake System Warning Light on page 3-22. 5-33 What to Add When you do need brake ﬂuid, use only DOT-3 brake ﬂuid. Use new brake ﬂuid from a sealed container only. See Part D: Recommended Fluids and Lubricants on page 6-24. 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: (cid:127) 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 will have to be replaced. Do not let someone put in the wrong kind of ﬂuid. 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 on page 5-70. Brake Wear Your vehicle has front disc brakes and may have rear drum brakes or rear 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. 5-34 (cid:127) {CAUTION: The brake wear warning sound means that soon your brakes will not 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. If you have rear drum brakes, they do not have wear indicators, but if you ever hear a rear brake rubbing noise, have the rear brake linings inspected immediately. Also, the rear brake drums should be removed and inspected each time the tires are removed for rotation or changing. When you have the front brake pads replaced, have the rear brakes inspected, too. Brake linings should always be replaced as complete axle sets. See Brake System Inspection on page 6-23. 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 make a moderate brake stop, your disc brakes adjust for wear. If you rarely make a moderate or heavier stop, then your brakes might not adjust correctly. If you drive in that way, then — very carefully — make a few moderate brake stops about every 1,000 miles (1 600 km), so your brakes will adjust properly. If your brake pedal goes down farther than normal, your rear drum brakes may need adjustment. Adjust them by backing up and ﬁrmly applying the brakes a few times. 5-35 Vehicle Storage If you are 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 are not careful. See Jump Starting on page 5-36 for tips on working around a battery without getting hurt. Jump Starting If your battery has run down, you may want to use another vehicle and some jumper cables to start your vehicle. Be sure to use the following steps to do it safely. 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 need new ones put in — be sure you get new approved GM replacement parts. If you do not, 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 have come to expect can change in many other ways if someone puts in the wrong replacement brake parts. Battery Your vehicle has a maintenance free battery. When it is time for a new battery, get one that has the replacement number shown on the original battery’s label. See Engine Compartment Overview on page 5-12 for battery location. Warning: Battery posts, terminals and related accessories contain lead and lead compounds, chemicals known to the State of California to cause cancer and reproductive harm. Wash hands after handling. 5-36 {CAUTION: Batteries can hurt you. They can be dangerous because: (cid:127) They contain acid that can burn you. (cid:127) They contain gas that can explode or (cid:127) They contain enough electricity to ignite. burn you. If you do not follow these steps exactly, some or all of these things can hurt you. Ignoring these steps could result in costly Notice: damage to your vehicle that would not be covered by your warranty. Trying to start your vehicle by pushing or pulling it will not work, and it could damage your vehicle. 1. Check the other vehicle. It must have a 12-volt battery with a negative ground system. 2. Get the vehicles close enough so the jumper cables can reach, but be sure the vehicles are not touching each other. If they are, it could cause a ground connection you do not want. You would not 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) or a manual transaxle in NEUTRAL before setting the parking brake. If you leave your radio or other accessories Notice: on during the jump starting procedure, they could be damaged. The repairs would not be covered by your warranty. Always turn off your radio and other accessories when jump starting your vehicle. 3. Turn off the ignition on both vehicles. Unplug unnecessary accessories plugged into the cigarette lighter or the accessory power outlet. Turn off the radio and all lamps that are not needed. This will avoid sparks and help save both batteries. And it could save the radio! If the other vehicle’s system is not a 12-volt Notice: system with a negative ground, both vehicles can be damaged. Only use vehicles with 12-volt systems with negative grounds to jump start your vehicle. 5-37 4. Open the hoods and locate the batteries. Find the positive (+) and negative (−) terminal locations on each vehicle. Your vehicle’s positive (+) terminal is located under a red tethered cap on the battery. See Engine Compartment Overview on page 5-12 for more information on location. Flip the cap up to access the positive (+) terminal. {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. {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 do not need to add water to the battery installed in your new 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. Do not 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. 5-38 {CAUTION: Fans or other moving engine parts can injure you badly. Keep your hands away from moving parts once the engine is running. 5. Check that the jumper cables do not have loose or missing insulation. If they do, you could get a shock. The vehicles could be damaged too. Before you connect the cables, here are some things you should know. Positive (+) will go to positive (+) or to a remote positive (+) terminal if the vehicle has one. Negative (−) will go to a heavy, unpainted metal engine part or to a remote negative (−) terminal if the vehicle has one. Do not connect positive (+) to negative (−) or you will get a short that would damage the battery and maybe other parts too. And do not connect the negative (−) cable to the negative (−) terminal on the dead battery because this can cause sparks. 6. Connect the red positive (+) cable to the positive (+) terminal of the dead battery. Use a remote positive (+) terminal if the vehicle has one. 7. Do not 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. 8. Now connect the black negative (−) cable to the negative (−) terminal of the good battery. Use a remote negative (−) terminal if the vehicle has one. Do not let the other end touch anything until the next step. The other end of the negative (−) cable does not go to the dead battery. It goes to a heavy, unpainted metal engine part or to a remote negative (−) terminal on the vehicle with the dead battery. 9. Connect the other end of the negative (−) cable at least 18 inches (45 cm) away from the dead battery, but not near engine parts that move. The electrical connection is just as good there, and the chance of sparks getting back to the battery is much less. 5-39 10. Now start the vehicle with the good battery and run the engine for a while. 11. Try to start the vehicle that had the dead battery. If it will not start after a few tries, it probably needs service. If the jumper cables are connected or Notice: removed in the wrong order, electrical shorting may occur and damage the vehicle. The repairs would not be covered by your warranty. Always connect and remove the jumper cables in the correct order, making sure that the cables do not touch each other or other metal. 5-40 Jumper Cable Removal A. Heavy, Unpainted Metal Engine Part or Remote Negative (–) Terminal B. Good Battery or Remote Positive (+) and Remote Negative (−) Terminals C. Dead Battery or Remote Positive (+) Terminal Bulb Replacement For the proper type of replacement bulbs, see Replacement Bulbs on page 5-47. For any bulb changing procedure not listed in this section, contact your dealer. 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. To disconnect the jumper cables from both vehicles, do the following: 1. Disconnect the black negative (−) cable from the vehicle that had the dead battery. 2. Disconnect the black negative (−) cable from the vehicle with the good battery. 3. Disconnect the red positive (+) cable from the vehicle with the good battery. 4. Disconnect the red positive (+) cable from the other vehicle. 5. Return the positive (+) terminal cap to its original position. Headlamp Aiming Headlamp aim has been preset at the factory and should need no further adjustment. If your vehicle is damaged in an accident, the headlamp aim may be affected. Aim adjustment to the low-beam headlamps may be necessary if it is difficult to see the lane markers (for horizontal aim), or if oncoming drivers ﬂash their high-beam headlamps 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. 5-41 Headlamps To replace a headlamp bulb, do the following: 1. Open the hood.

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 GM Warranty booklet for details. For additional information refer to the tire manufacturer’s booklet included with your vehicle’s Owner Manual. 5-48 {CAUTION: Poorly maintained and improperly used tires are dangerous. (cid:127) Overloading your tires can cause overheating as a result of too much friction. You could have an air-out and a serious accident. See Loading Your Vehicle on page 4-29. (cid:127) Underinﬂated tires pose the same danger as overloaded tires. The resulting accident could cause serious injury. Check all tires frequently to maintain the recommended pressure. Tire pressure should be checked when your tires are cold. See Inﬂation - Tire Pressure on page 5-54. (cid:127) Overinﬂated tires are more likely to be cut, punctured or broken by a sudden impact — such as when you hit a pothole. Keep tires at the recommended pressure. (cid:127) Worn, old tires can cause accidents. If your tread is badly worn, or if your tires have been damaged, replace them. Tire Sidewall Labelling Useful information about a tire is molded into its sidewall. The examples below show a typical passenger car tire and a compact spare tire sidewall. Passenger Car Tire Example (A) Tire Size: The tire size is a combination of letters and numbers used to deﬁne a particular tire’s width, height, aspect ratio, construction type and service description.

The amount of grip provided. Tread: The portion of a tire that comes into contact with the road. Treadwear Indicators: Narrow bands, sometimes called “wear bars,” that show across the tread of a tire when only 1/16 inch (1.6 mm) of tread remains. See When It Is Time for New Tires on page 5-57. UTQGS (Uniform Tire Quality Grading Standards): A tire information system that provides consumers with ratings for a tire’s traction, temperature, and treadwear. Ratings are determined by tire manufacturers using government testing procedures. The ratings are molded into the sidewall of the tire. See Uniform Tire Quality Grading on page 5-58. Vehicle Capacity Weight: The number of designated seating positions multiplied by 150 lbs (68 kg) plus the rated cargo load. See Loading Your Vehicle on page 4-29. 5-53 If your tires have too much air (over-inﬂation), you can get the following: (cid:127) Unusual wear (cid:127) Poor handling (cid:127) Rough ride (cid:127) Needless damage from road hazards A Tire and Loading Information label is attached to the vehicle’s center pillar (B-pillar), below the driver’s door latch. This label shows your vehicle’s original equipment tires and the correct inﬂation pressures for your tires when they are cold. The recommended cold tire inﬂation pressure, shown on the label, is the minimum amount of air pressure needed to support your vehicle’s maximum load carrying capacity. For additional information regarding how much weight your vehicle can carry, and an example of the tire and loading information label, see Loading Your Vehicle on page 4-29. How you load your vehicle affects vehicle handling and ride comfort, never load your vehicle with more weight than it was designed to carry. Vehicle Maximum Load on the Tire: Load on an individual tire due to curb weight, accessory weight, occupant weight, and cargo weight. Vehicle Placard: A label permanently attached to a vehicle showing the vehicle’s capacity weight and the original equipment tire size and recommended inﬂation pressure. See “Tire and Loading Information Label” under Loading Your Vehicle on page 4-29. Inﬂation - Tire Pressure Tires need the correct amount of air pressure to operate effectively. Notice: Do not let anyone tell you that under-inﬂation or over-inﬂation is all right. It is not. If your tires do not have enough air (under-inﬂation), you can get the following: Too much ﬂexing Too much heat Tire overloading (cid:127) Premature or irregular wear (cid:127) Poor handling (cid:127) Reduced fuel economy 5-54 (cid:127) (cid:127) (cid:127) When to Check Check your tires once a month or more. Do not forget to check the compact spare tire, it should be at 60 psi (420 kPa). For additional information regarding the compact spare tire, see Compact Spare Tire on page 5-70. How to Check Use a good quality pocket-type gage to check tire pressure. You cannot tell if your tires are properly inﬂated simply by looking at them. Radial tires may look properly inﬂated even when they are under-inﬂated. Check the tire’s inﬂation pressure when the tires are cold. Cold means your vehicle has been sitting for at least three hours or driven no more than 1 mile (1.6 km). Remove the valve cap from the tire valve stem. Press the tire gage ﬁrmly onto the valve to get a pressure measurement. If the cold tire inﬂation pressure matches the recommended pressure on the Tire and Loading Information label, no further adjustment is necessary. If the inﬂation pressure is low, add air until you reach the recommended amount. If you overﬁll the tire, release air by pushing on the metal stem in the center of the tire valve. Re-check the tire pressure with the tire gage. Be sure to put the valve caps back on the valve stems. They help prevent leaks by keeping out dirt and moisture. Tire Inspection and Rotation Tires should be rotated every 5,000 to 8,000 miles (8 000 to 13 000 km). Any time you notice unusual wear, rotate your tires as soon as possible and check wheel alignment. Also check for damaged tires or wheels. See When It Is Time for New Tires on page 5-57 and Wheel Replacement on page 5-60 for more information. 5-55 The purpose of regular rotation is to achieve more uniform wear for all tires on the vehicle. The ﬁrst rotation is the most important. See Part A: Scheduled Maintenance Services on page 6-4. When rotating your tires, always use the correct rotation pattern shown here. Do not include the compact spare tire in the tire rotation. 5-56 After the tires have been rotated, adjust the front and rear inﬂation pressures as shown on the tire and loading information label. See Loading Your Vehicle on page 4-29 for an example of the tire and loading information label and where it is located on your vehicle. Make certain that all wheel nuts are properly tightened. See “Wheel Nut Torque” under Capacities and Speciﬁcations on page 5-85. {CAUTION: Rust or dirt on a wheel, or on the parts to which it is fastened, can make wheel nuts become loose after a time. The wheel could come off and cause an accident. When you change a wheel, remove any rust or dirt from places where the wheel attaches to the vehicle. In an emergency, you can use a cloth or a paper towel to do this; but be sure to use a scraper or wire brush later, if needed, to get all the rust or dirt off. See Changing a Flat Tire on page 5-62. When It Is Time for New Tires One way to tell when it’s time for new tires is to check the treadwear indicators, which will appear when your tires have only 1/16 inch (1.6 mm) or less of tread remaining. You need a new tire if any of the following statements are true: • You can see the indicators at three or more places around the tire. • You can see cord or fabric showing through the tire’s rubber. • The tread or sidewall is cracked, cut or snagged deep enough to show cord or fabric. • The tire has a bump, bulge or split. • The tire has a puncture, cut or other damage that can’t be repaired well because of the size or location of the damage. 5-57 Buying New Tires To ﬁnd out what kind and size of tires you need, look at the tire and loading information label attached to your vehicle. See Loading Your Vehicle on page 4-29 for a label example and where it is attached to your vehicle. Make sure the replacements are the same size, load range, speed rating and construction type (bias, bias-belted or radial) as your original tires. {CAUTION: Mixing tires could cause you to lose control while driving. If you mix tires of different sizes or types (radial and bias-belted tires), the vehicle may not handle properly, and you could have a crash. Using tires of different sizes may also cause damage to your vehicle. Be sure to use the same size and type tires on all wheels. It’s all right to drive with your compact spare temporarily, it was developed for use on your vehicle. See Compact Spare Tire on page 5-70. 5-58 {CAUTION: If you use bias-ply tires on your vehicle, the wheel rim ﬂanges could develop cracks after many miles of driving. A tire and/or wheel could fail suddenly, causing a crash. Use only radial-ply tires with the wheels on your vehicle. Uniform Tire Quality Grading Quality grades can be found where applicable on the tire sidewall between tread shoulder and maximum selection width. For example: Treadwear 200 Traction AA Temperature A The following information relates to the system developed by the Unites States National Highway Traffic Safety Administration, which grades tires by treadwear, traction and temperature performance. (This applies only to vehicles sold in the United States.) The grades are molded on the sidewalls of most passenger car tires. The Uniform Tire Quality Grading system does not apply to deep tread, winter-type snow tires, space-saver or temporary use spare tires, tires with nominal rim diameters of 10 to 12 inches (25 to 30 cm), or to some limited-production tires. Temperature — A, B, C The temperature grades are A (the highest), B, and C, representing the tire’s resistance to the generation of heat and its ability to dissipate heat when tested under controlled conditions on a speciﬁed indoor laboratory test wheel. Sustained high temperature can cause the material of the tire to degenerate and reduce tire life, and excessive temperature can lead to sudden tire failure. The grade C corresponds to a level of performance which all passenger car tires must meet under the Federal Motor Vehicle Safety Standard No. 109. Grades B and A represent higher levels of performance on the laboratory test wheel than the minimum required by law. Warning: The temperature grade for this tire is established for a tire that is properly inﬂated and not overloaded. Excessive speed, underinﬂation, or excessive loading, either separately or in combination, can cause heat buildup and possible tire failure. While the tires available on General Motors passenger cars and light trucks may vary with respect to these grades, they must also conform to federal safety requirements. Treadwear The treadwear grade is a comparative rating based on the wear rate of the tire when tested under controlled conditions on a speciﬁed government test course. For example, a tire graded 150 would wear one and a half (11⁄2) times as well on the government course as a tire graded 100. The relative performance of tires depends upon the actual conditions of their use, however, and may depart signiﬁcantly from the norm due to variations in driving habits, service practices and differences in road characteristics and climate. Traction — AA, A, B, C The traction grades, from highest to lowest, are AA, A, B, and C. Those grades represent the tire’s ability to stop on wet pavement as measured under controlled conditions on speciﬁed government test surfaces of asphalt and concrete. A tire marked C may have poor traction performance. Warning: The traction grade assigned to this tire is based on straight-ahead braking traction tests, and does not include acceleration, cornering, hydroplaning, or peak traction characteristics. 5-59 Wheel Alignment and Tire Balance The tires and wheels on your vehicle were aligned and balanced carefully at the factory to give you the longest tire life and best overall performance. Adjustments to wheel alignment and tire balancing will not be necessary on a regular basis. However, if you notice unusual tire wear or your vehicle pulling to one side or the other, the alignment may need to be checked. If you notice your vehicle vibrating when driving on a smooth road, your tires and wheels may need to be rebalanced. See your dealer for proper diagnosis. Wheel Replacement Replace any wheel that is bent, cracked or badly rusted or corroded. If wheel nuts keep coming loose, the wheel, wheel bolts and wheel nuts should be replaced. If the wheel leaks air, replace it (except some aluminum wheels, which can sometimes be repaired). See your dealer if any of these conditions exist. Your dealer will know the kind of wheel you need. Each new wheel should have the same load-carrying capacity, diameter, width, offset and be mounted the same way as the one it replaces. If you need to replace any of your wheels, wheel bolts or wheel nuts, replace them only with new GM original equipment parts. This way, you will be sure to have the right wheel, wheel bolts and wheel nuts for your vehicle. {CAUTION: Using the wrong replacement wheels, wheel bolts or wheel nuts on your vehicle can be dangerous. It could affect the braking and handling of your vehicle, make your tires lose air and make you lose control. You could have a collision in which you or others could be injured. Always use the correct wheel, wheel bolts and wheel nuts for replacement. 5-60 Notice: The wrong wheel can also cause problems with bearing life, brake cooling, speedometer or odometer calibration, headlamp aim, bumper height, vehicle ground clearance and tire or tire chain clearance to the body and chassis. See Changing a Flat Tire on page 5-62 for more information. Used Replacement Wheels {CAUTION: Putting a used wheel on your vehicle is dangerous. You can’t know how it’s been used or how far it’s been driven. It could fail suddenly and cause a crash. If you have to replace a wheel, use a new GM original equipment wheel. Tire Chains Notice: Use tire chains only where legal and only when you must. Use only SAE Class “S” type chains that are the proper size for your tires. Install them on the front tires and tighten them as tightly as possible with the ends securely fastened. Drive slowly and follow the chain manufacturer’s instructions. If you can hear the chains contacting your vehicle, stop and retighten them. If the contact continues, slow down until it stops. Driving too fast or spinning the wheels with chains on will damage your vehicle. If a Tire Goes Flat It is unusual for a tire to blowout while you’re driving, especially if you maintain your tires properly. If air goes out of a tire, it is much more likely to leak out slowly. But if you should ever have a blowout, here are a few tips about what to expect and what to do: If a front tire fails, the ﬂat tire will create a drag that pulls the vehicle toward that side. Take your foot off the accelerator pedal and grip the steering wheel ﬁrmly. Steer to maintain lane position, and then gently brake to a stop well out of the traffic lane. 5-61 A rear blowout, particularly on a curve, acts much like a skid and may require the same correction you would; use in a skid. In any rear blowout, remove your foot from the accelerator pedal. Get the vehicle under control by steering the way you want the vehicle to go. It may be very bumpy and noisy, but you can still steer. Gently brake to a stop, well off the road if possible. {CAUTION: Lifting a vehicle and getting under it to do maintenance or repairs is dangerous without the appropriate safety equipment and training. The jack provided with your vehicle is designed only for changing a ﬂat tire. If it is used for anything else, you or others could be badly injured or killed if the vehicle slips off the jack. Use the jack provided with your vehicle only for changing a ﬂat tire. If a tire goes ﬂat, the next part shows how to use 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 be dangerous. The vehicle can slip off the jack and roll over or fall on you or other people. You and they could be badly injured or even killed. Find a level place to change your tire. To help prevent the vehicle from moving: 1. Set the parking brake ﬁrmly. 2. Put an automatic transaxle shift lever in PARK (P), or shift a manual transaxle to FIRST (1) or REVERSE (R). CAUTION: (Continued) 5-62 When you have a ﬂat tire, use the following example as a guide to assist you in the placement of wheel blocks. CAUTION: (Continued) 3. Turn off the engine and do not restart while the vehicle is raised. 4. Do not allow passengers to remain in the vehicle. To be even more certain the vehicle will not move, you should put blocks at the front and rear of the tire farthest away from the one being changed. That would be the tire on the other side, at the opposite end of the vehicle. The following information will tell you how to use the jack and change a tire. 5-63 Removing the Spare Tire and Tools The compact spare tire and tools you will need are located in the trunk. A. Jack B. Wheel Wrench C. Jack Handle D. Screwdriver 1. Open the trunk or liftgate. See Trunk (Sedan) on page 2-9 or Liftgate (Hatchback) on page 2-11 for more information. 2. Lift the trim cover. 5-64 3. Remove the foam tray. 4. Remove the jack, the jack handle and the wheel wrench from the foam tray. 5. Turn the retainer counterclockwise and remove it from the compact spare. 6. Remove the compact spare tire. See Compact Spare Tire on page 5-70 for more information. Removing the Flat Tire and Installing the Spare Tire 1. If your vehicle has wheel covers, loosen the four plastic caps by hand or by using the wheel wrench. The plastic nuts do not come off of the cover. 2. Remove the wheel cover using the ﬂat end of the jack handle or the screwdriver. Pry along the edge of the wheel cover until it comes off. 3. Use the wheel wrench to loosen all the wheel nuts. Do not remove them yet. 5-65 Hatchback shown, Sedan similar 4. Locate the notch in the frame near each wheel which the jack head ﬁts in. 5. Position the jack and raise the jack head until it ﬁts ﬁrmly into the notch in the vehicle’s frame nearest the ﬂat tire. 6. Put the compact spare tire near you. 7. Insert the jack handle into the jack and the wheel wrench onto the end of the jack handle. {CAUTION: Getting under a vehicle when it is jacked up is dangerous. If the vehicle slips off the jack you could be badly injured or killed. Never get under a vehicle when it is supported only by a jack. 5-66 {CAUTION: {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. 8. Raise the vehicle by turning the wheel wrench clockwise. Raise the vehicle far enough off the ground so there is enough room for the compact spare tire to ﬁt underneath the wheel well. 9. Remove all of the wheel nuts by turning them counterclockwise. 10. Remove the ﬂat tire. Rust or dirt on the wheel, or on the parts to which it is fastened, can make the wheel nuts
