How heavy can a trailer safely be? It should never weigh more than 1,000 lbs (454 kg). But even that can be too heavy. It depends on how you plan to use your rig. For example, speed, altitude, road grades, outside temperature and how much your vehicle is used to pull a trailer are all important. It can also depend on any special equipment that you have on your vehicle, and the amount of tongue weight the vehicle can carry. See “Weight of the Trailer Tongue” later in this section for more information. Maximum trailer weight is calculated assuming only the driver is in the tow vehicle and it has all the required trailering equipment. The weight of additional optional equipment, passengers and cargo in the tow vehicle must be subtracted from the maximum trailer weight. 285 You can ask your dealer for our trailering information or advice, or you can write us at: Chevrolet Customer Assistance Center P.O. Box 33170 Detroit, MI 48232-5170 In Canada, write to: General Motors of Canada Limited Customer Communication Centre, 163-005 1908 Colonel Sam Drive Oshawa, Ontario L1H 8P7 Weight of the Trailer Tongue The tongue load (A) of any trailer is an important weight to measure because it affects the total or gross weight of your vehicle. The Gross Vehicle Weight (GVW) includes the curb weight of the vehicle, any cargo you may carry in it, and the people who will be riding in the vehicle. And if you tow a trailer, you must add the tongue load to the GVW because your vehicle will be carrying that weight, too. See Loading Your Vehicle on page 277 for more information about your vehicle’s maximum load capacity. 286 If you’re using a weigh-carrying hitch or a weight-distributing hitch, the trailer tongue (A) should weigh 10 to 15 percent of the total loaded trailer weight (B). After you’ve loaded your trailer, weigh the trailer and then the tongue, separately, to see if the weights are proper. If they aren’t, you may be able to get them right simply by moving some items around in the trailer. Total Weight on Your Vehicle’s Tires Be sure your vehicle’s tires are inﬂated to the upper limit for cold tires. You’ll ﬁnd these numbers on the Tire-Loading Information label, See Loading Your Vehicle on page 277. Then be sure you don’t go over the GVW limit for your vehicle, including the weight of the trailer tongue. Hitches It’s important to have the correct hitch equipment. Crosswinds, large trucks going by and rough roads are a few reasons why you’ll need the right hitch. Here are some rules to follow: (cid:127) The rear bumper on your vehicle is not intended for hitches. Do not attach rental hitches or other bumper-type hitches to it. Use only a frame-mounted hitch that does not attach to the bumper. (cid:127) Will you have to make any holes in the body of your vehicle when you install a trailer hitch? If you do, then be sure to seal the holes later when you remove the hitch. If you don’t seal them, deadly carbon monoxide (CO) from your exhaust can get into your vehicle. See Engine Exhaust on page 121. Dirt and water can, too. Safety Chains You should always attach chains between your vehicle and your trailer. Cross the safety chains under the tongue of the trailer so that the tongue will not drop to the road if it becomes separated from the hitch. Instructions about safety chains may be provided by the hitch manufacturer or by the trailer manufacturer. Follow the manufacturer’s recommendation for attaching safety chains and do not attach them to the bumper. Always leave just enough slack so you can turn with your rig. And, never allow safety chains to drag on the ground. Trailer Brakes Does your trailer have its own brakes? Be sure to read and follow the instructions for the trailer brakes so you’ll be able to install, adjust and maintain them properly. Your vehicle may have anti-lock brakes. Do not try to tap into your vehicle’s brake system. If you do, both brake systems won’t work well, or at all. 287 Driving with a Trailer Towing a trailer requires a certain amount of experience. Before setting out for the open road, you’ll want to get to know your rig. Acquaint yourself with the feel of handling and braking with the added weight of the trailer. And always keep in mind that the vehicle you are driving is now a good deal longer and not nearly as responsive as your vehicle is by itself. Before you start, check the trailer hitch and platform (and attachments), safety chains, electrical connector, lamps, tires and mirror adjustment. If the trailer has electric brakes, start your vehicle and trailer moving and then apply the trailer brake controller by hand to be sure the brakes are working. This lets you check your electrical connection at the same time. During your trip, check occasionally to be sure that the load is secure, and that the lamps and any trailer brakes are still working. Following Distance Stay at least twice as far behind the vehicle ahead as you would when driving your vehicle without a trailer. This can help you avoid situations that require heavy braking and sudden turns. Passing You’ll need more passing distance up ahead when you’re towing a trailer. And, because you’re a good deal longer, you’ll need to go much farther beyond the passed vehicle before you can return to your lane. Backing Up Hold the bottom of the steering wheel with one hand. Then, to move the trailer to the left, just move that hand to the left. To move the trailer to the right, move your hand to the right. Always back up slowly and, if possible, have someone guide you. 288 Making Turns Notice: Making very sharp turns while trailering could cause the trailer to come in contact with the vehicle. Your vehicle could be damaged. Avoid making very sharp turns while trailering. When you’re turning with a trailer, make wider turns than normal. Do this so your trailer won’t strike soft shoulders, curbs, road signs, trees or other objects. Avoid jerky or sudden maneuvers. Signal well in advance. Turn Signals When Towing a Trailer When you tow a trailer, your vehicle may need additional wiring. Check with your dealer. The arrows on your instrument panel will ﬂash whenever you signal a turn or lane change. Properly hooked up, the trailer lamps will also ﬂash, telling other drivers you’re about to turn, change lanes or stop. When towing a trailer, the arrows on your instrument panel will ﬂash for turns even if the bulbs on the trailer are burned out. Thus, you may think drivers behind you are seeing your signal when they are not. It’s important to check occasionally to be sure the trailer bulbs are still working. 289 Driving On Grades Reduce speed and shift to a lower gear before you start down a long or steep downgrade. If you don’t shift down, you might have to use your brakes so much that they would get hot and no longer work well. On a long uphill grade, shift down and reduce your speed to around 45 mph (70 km/h) to reduce the possibility of engine and transaxle overheating. Notice: When the outside temperature is above 100° F (38° C) and/or there is a steep, continuous grade, the recommended speed when towing is 55 mph (88 km/h) or less. Extended higher than normal engine and transaxle temperatures may damage your vehicle. You may want to drive in THIRD (3), instead of DRIVE (D). 290 Parking on Hills {CAUTION: You really should not park your vehicle, with a trailer attached, on a hill. If something goes wrong, your rig could start to move. People can be injured, and both your vehicle and the trailer can be damaged. But if you ever have to park your rig on a hill, here’s how to do it: 1. Apply your regular brakes, but don’t shift into PARK (P) yet. 2. Have someone place chocks under the trailer wheels. 3. When the wheel chocks are in place, release the regular brakes until the chocks absorb the load. 4. Reapply the regular brakes. Then apply your parking brake, and then shift to PARK (P). 5. Release the regular brakes. When You Are Ready to Leave After Parking on a Hill 1. Apply your regular brakes and hold the pedal down while you: (cid:127) start your engine, (cid:127) shift into a gear, and (cid:127) release the parking brake. 2. Let up on the brake pedal. 3. Drive slowly until the trailer is clear of the chocks. 4. Stop and have someone pick up and store the chocks. Maintenance When Trailer Towing Your vehicle will need service more often when you’re pulling a trailer. See the Maintenance Schedule for more on this. Things that are especially important in trailer operation are automatic transaxle ﬂuid (don’t overﬁll), engine oil, drive belts, cooling system and brake system. Each of these is covered in this manual, and the Index will help you ﬁnd them quickly. If you’re trailering, it’s a good idea to review this information before you start your trip. Check periodically to see that all hitch nuts and bolts are tight. Engine Cooling When Trailer Towing Your cooling system may temporarily overheat during severe operating conditions.

We hope you will go to your dealer for all your service needs. You will get genuine GM parts and GM-trained and supported service people. We hope you will want to keep your GM vehicle all GM. Genuine GM parts have one of these marks: Accessories and Modiﬁcations When you add non-GM accessories to your vehicle they can affect your vehicle’s performance and safety, including such things as, airbags, braking, stability, ride and handling, emissions systems, aerodynamics, durability, and electronic systems like anti-lock brakes, traction control and stability control. Some of these accessories may even cause malfunction or damage not covered by warranty. GM Accessories are designed to complement and function with other systems on your vehicle. Your GM dealer can accessorize your vehicle using genuine GM Accessories. When you go to your GM dealer and ask for GM Accessories, you will know that GM-trained and supported service technicians will perform the work using genuine GM Accessories. 296 California Proposition 65 Warning Most motor vehicles, including this one, contain and/or emit chemicals known to the State of California to cause cancer and birth defects or other reproductive harm. Engine exhaust, many parts and systems (including some inside the vehicle), many ﬂuids, and some component wear by-products contain and/or emit these chemicals. Doing Your Own Service Work {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. (cid:127) Be sure you have sufficient knowledge, experience, the proper replacement parts, and tools before you attempt any vehicle maintenance task. CAUTION: (Continued) CAUTION: (Continued) (cid:127) 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. If you want to do some of your own service work, you will 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 Publications Ordering Information on page 441. Your vehicle has an airbag system. Before attempting to do your own service work, see Servicing Your Airbag-Equipped Vehicle on page 82. 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 on page 418. 297 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 Use of the recommended fuel is an important part of the proper maintenance of your vehicle. To help keep your engine clean and maintain optimum vehicle performance, GM recommends the use of gasoline advertised as TOP TIER Detergent Gasoline. The 8th digit of your Vehicle Identiﬁcation Number (VIN) shows the code letter or number that identiﬁes your engine. You will ﬁnd the VIN at the top left of the instrument panel. See Vehicle Identiﬁcation Number (VIN) on page 394. If your vehicle has the 3.5L V6 engine (VIN Code K only), you may use either regular unleaded gasoline or ethanol fuel containing up to 85% ethanol (E85); also see Fuel E85 (85% Ethanol) on page 301. In all other engines, use only regular unleaded gasoline. Gasoline Octane For all vehicles except those with the 5.3L V8 engine (VIN Code C), use regular unleaded gasoline with a posted octane rating of 87 or higher. If the octane rating is less than 87, you may notice an audible knocking noise when you drive, commonly referred to as spark knock. If this occurs, use a gasoline rated at 87 octane or higher as soon as possible. If you are using gasoline rated at 87 octane or higher and you hear heavy knocking, your engine needs service. 298 California Fuel If your vehicle is certiﬁed to meet California Emissions 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 181. 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. If your vehicle has the 5.3L V8 engine (VIN Code C), use premium unleaded gasoline with a posted octane rating of 91 or higher. You may also use regular unleaded gasoline rated at 87 octane or higher, but your vehicle’s acceleration may be slightly reduced, and you may notice a slight audible knocking noise, commonly referred to as spark knock. If the octane is less than 87, you may notice 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. If you are using gasoline rated at 87 octane or higher and you hear heavy knocking, your engine needs service. Gasoline Speciﬁcations At a minimum, gasoline should meet ASTM speciﬁcation D 4814 in the United States or CAN/CGSB-3.5 in Canada. Some gasolines may contain an octane-enhancing additive called methylcyclopentadienyl manganese tricarbonyl (MMT). General Motors recommends against the use of gasolines containing MMT. See Additives on page 300 for additional information. 299 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. 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 recommends against 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 dealer for service. 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. To help keep fuel injectors and intake valves clean, or if your vehicle experiences problems due to dirty injectors or valves, look for gasoline that is advertised as TOP TIER Detergent Gasoline. Also, your 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. General Motors recommends that you use these gasolines if they comply with the speciﬁcations described earlier. However, E85 (85% ethanol) and other fuels containing more than 10% ethanol must not be used in vehicles that were not designed for those fuels. 300 Fuel E85 (85% Ethanol) The 8th digit of your Vehicle Identiﬁcation Number (VIN) shows the code letter or number that identiﬁes your engine. You will ﬁnd the VIN at the top left of the instrument panel. See Vehicle Identiﬁcation Number (VIN) on page 394. If your vehicle has the 3.5L V6 engine (VIN Code K only), you may use either regular unleaded gasoline or ethanol fuel containing up to 85% ethanol (E85); also see Fuel on page 298. In all other engines, including the 3.5L V6 (VIN Code N), use only regular unleaded gasoline. Only vehicles that have the 3.5L V6 engine (VIN Code K) may use 85% ethanol fuel (E85). General Motors encourages the use of E85 in vehicles that are designed to use it. The ethanol in E85 is a “renewable” fuel, meaning it is made from renewable sources such as corn and other crops. Many service stations will not have an 85% ethanol fuel (E85) pump available. The U. S. Department of Energy has an alternative fuels website (www.eere.energy.gov/afdc/infrastructure/ locator.html) that can help you ﬁnd E85 fuel. Those stations that do have E85 should have a label indicating ethanol content. Do not use the fuel if the ethanol content is greater than 85%. At a minimum, E85 should meet ASTM Speciﬁcation D 5798. By deﬁnition, this means that fuel labeled E85 will have an ethanol content between 70% and 85%. Filling the fuel tank with fuel mixtures that do not meet ASTM speciﬁcations can affect driveability and could cause the check engine light to come on. 301 To ensure quick starts in the wintertime, the E85 fuel must be formulated properly for your climate according to ASTM speciﬁcation D 5798. If you have trouble starting on E85, it may be because your E85 fuel is not properly formulated for your climate. If this happens, switching to gasoline or adding gasoline to your fuel tank may improve starting. For good starting and heater efficiency below 32°F (0°C), the fuel mix in the fuel tank should contain no more than 70% ethanol. It is best not to alternate repeatedly between gasoline and E85. If you do switch fuels, it is recommended that you add as much fuel as possible — do not add less than three gallons (11 L) when refueling. You should drive the vehicle immediately after refueling for at least seven miles (11 km) to allow the vehicle to adapt to the change in ethanol concentration. E85 has less energy per gallon than gasoline, so you will need to reﬁll your fuel tank more often when using E85 than when you are using gasoline. See Filling the Tank on page 303. Notice: Some additives are not compatible with E85 fuel and may harm your vehicle’s fuel system. Damage caused by additives would not be covered by your new vehicle warranty. 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. 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. 302 Filling the 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. The tethered fuel cap is located behind a hinged fuel door on the driver’s side of the vehicle. If the vehicle has E85 fuel capability, a yellow cap with the words “E85/gasoline” can be seen. To remove the fuel cap, turn it slowly counterclockwise. The fuel cap has a spring in it; if the cap is released too soon, it will spring back to the right. 303 While refueling, hang the tethered fuel cap on the hook on the inside of the fuel door. {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 389. When replacing the fuel cap, turn it 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 181. 304 The TIGHTEN GAS CAP message will be displayed on the Driver Information Center (DIC) if the fuel cap is not properly installed. See DIC Warnings and Messages on page 195 for more information. {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 Notice: 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 may damage your fuel tank and emissions system. See Malfunction Indicator Lamp on page 181. CAUTION: (Continued) (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. 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. CAUTION: (Continued) 305 Checking Things Under the Hood {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. 306 Hood Release To open the hood, do the following: 1. Pull the interior hood release handle with this symbol on it. It is located to the left of the parking brake pedal. 2. Then go to the front of the vehicle and release the secondary hood latch, located near the center of the hood front, by pushing the latch to the right. 3. 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. 307 Engine Compartment Overview When you open the hood on the 3.5L V6 engine, this is what you will see: 308 A. Windshield Washer Fluid Reservoir.

See Engine Air Cleaner/Filter on page 316. L. Coolant Recovery Tank. See “Checking Coolant” under Cooling System on page 326. Engine Oil If the ENGINE OIL LOW ADD OIL message appears in the Driver Information Center (DIC), it means you need to check the engine oil level right away. For more information, see DIC Warnings and Messages on page 195. You should check the engine oil level regularly; this is an added reminder. Checking Engine Oil It is a good idea to check the 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 308 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 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. 311 When to Add Engine Oil V6 Engine Notice: Do not add too much oil. If the engine has so much oil that the oil level gets above the cross-hatched area that shows the proper operating range, the engine could be damaged. See Engine Compartment Overview on page 308 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 in the cross-hatched area. Push the dipstick all the way back in when you are through. V8 Engine If the oil is below the cross-hatched area at the tip of the dipstick, you will need to add at least one quart/liter 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 400. 312 What Kind of Engine Oil to Use 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. 313 Look for two things: (cid:127) 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. (cid:127) SAE 5W-30 As shown in the viscosity chart, SAE 5W-30 is best for your vehicle. When the system has calculated that oil life has been diminished, it will indicate that an oil change is necessary. A CHANGE ENGINE OIL SOON message will come on. See DIC Warnings and Messages on page 195. Change your oil as soon as possible within the next 600 miles (1 000 km). It is possible that, if you are driving under the best conditions, the oil life system may not indicate that an oil change is necessary for over a year. However, your engine oil and ﬁlter must be changed at least once a year and at this time the system must be reset. Your dealer has GM-trained service people who will perform this work using genuine GM parts and reset the system. It is also important to check your oil regularly and keep it at the proper level. If the system is ever reset accidentally, you must change your oil at 3,000 miles (5 000 km) since your last oil change. Remember to reset the oil life system whenever the oil is changed. 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 the engine at extremely low temperatures. Engine Oil Additives Do not add anything to the oil. The recommended oils with the starburst symbol that meet GM Standard GM6094M are all you will need for good performance and engine protection. Engine Oil Life System When to Change Engine Oil Your vehicle has a computer system that lets you know when to change the engine oil and ﬁlter. This is based on engine revolutions and engine temperature, and not on mileage. Based on driving conditions, the mileage at which an oil change will be indicated can vary considerably. For the oil life system to work properly, you must reset the system every time the oil is changed. 314 How to Reset the Engine Oil Life System The Engine Oil Life System calculates when to change your engine oil and ﬁlter based on vehicle use. Anytime your oil is changed, reset the system so it can calculate when the next oil change is required. If a situation occurs where you change your oil prior to a CHANGE ENGINE OIL SOON message being turned on, reset the system. Always reset the engine oil life to 100% after every oil change. It will not reset itself. To reset the Engine Oil Life System, do the following: 1. Display the OIL LIFE REMAINING on the DIC. 2. Press and hold the SET/RESET button on the DIC for more than ﬁve seconds. The oil life will change to 100%. If the CHANGE ENGINE OIL SOON message comes back on when you start your vehicle, the Engine Oil Life System has not reset. Repeat the procedure. 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 used oil, ask your dealer, a service station, or a local recycling center for help. 315 Engine Air Cleaner/Filter The engine air cleaner/ﬁlter is located in the engine compartment on the driver’s side of the vehicle. See Engine Compartment Overview on page 308 for more information on location. When to Inspect the Engine Air Cleaner/Filter Inspect the air cleaner/ﬁlter at the Maintenance II intervals and replace it at the ﬁrst oil change after each 50,000 mile (83 000 km) interval. See Scheduled Maintenance on page 406 for more information. 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 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. 316 To inspect or replace the engine air cleaner/ﬁlter do the following: 1. Lift the ﬁlter cover tabs on top of the engine air cleaner/ﬁlter housing. 2. Push the ﬁlter cover housing toward the engine. 3. Pull out the ﬁlter. 4. Inspect or replace the engine air cleaner/ﬁlter. 5. To reinstall the cover, position the tabs through the hinges on the housing. 6. Push the cover tabs on top of the housing to lock the cover in place. Automatic Transaxle Fluid When to Check and Change Automatic Transaxle Fluid A good time to check your automatic transaxle ﬂuid level is when the engine oil is changed. Change the ﬂuid and ﬁlter at the intervals listed in Additional Required Services on page 409, and be sure to use the transaxle ﬂuid listed in Recommended Fluids and Lubricants on page 415. {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 ﬂames 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. 317 How to Check Automatic Transaxle Fluid 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. Wait at least 30 minutes before checking the transaxle ﬂuid level if you have been driving: (cid:127) When outside temperatures are above 90°F (32°C). (cid:127) At high speed for quite a while. (cid:127) (cid:127) While pulling a trailer. In heavy traffic — especially in hot weather. 318 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 is colder than 50°F (10°C), you may have to drive longer. Checking the Fluid Level Prepare your vehicle as follows: 1. Park your vehicle on a level place. Keep the engine running. 2. With the parking brake applied, place the shift lever in PARK (P). 3. 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). 4. Let the engine run at idle for three to ﬁve minutes. Then, without shutting off the engine, follow these steps: 1. Pull out the dipstick and wipe it with a clean rag or paper towel. The transaxle ﬂuid dipstick handle is the black loop with this symbol on it. It is located near the rear of the engine compartment. See Engine Compartment Overview on page 308 for more information on location. 2. Push it back in all the way, wait three seconds and then pull it back out again. V6 Engines 5.3L 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. 319 How to Add Fluid Refer to the Maintenance Schedule to determine what kind of transaxle ﬂuid to use. See Recommended Fluids and Lubricants on page 415. 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 does not take much ﬂuid, generally less than one pint (0.5 L). Do not overﬁll. Notice: Use of the incorrect automatic transaxle ﬂuid may damage your vehicle, and the damages may not be covered by your warranty. Always use the automatic transaxle ﬂuid listed in Recommended Fluids and Lubricants on page 415. 3. After adding ﬂuid, recheck the ﬂuid level as described under “How to Check Automatic Transaxle Fluid,” earlier in this section. 4. When the correct ﬂuid level is obtained, push the dipstick back in all the way. 320 Engine Coolant The cooling system in your vehicle is ﬁlled with DEX-COOL® engine coolant. This coolant is designed to remain in your vehicle for ﬁve years or 150,000 miles (240 000 km), whichever occurs ﬁrst, if you add only DEX-COOL® 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 or if you need to add coolant to the radiator, see Engine Overheating on page 323. A 50/50 mixture of clean, drinkable water and DEX-COOL® coolant will: (cid:127) Give freezing protection down to −34°F (−37°C). (cid:127) Give boiling protection up to 265°F (129°C). (cid:127) Protect against rust and corrosion. (cid:127) Help keep the proper engine temperature. (cid:127) Let the warning lights and gages work as they should. Notice: Using coolant other than DEX-COOL® may cause premature engine, heater core, or radiator corrosion. In addition, the engine coolant may require changing sooner, at the ﬁrst maintenance service after each 30,000 miles (50 000 km) or 24 months, whichever occurs ﬁrst. Any repairs would not be covered by your warranty. Always use DEX-COOL® (silicate-free) coolant in your vehicle. What to Use Use a mixture of one-half clean, drinkable water and one-half DEX-COOL® coolant which will not damage aluminum parts. 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 CAUTION: (Continued) CAUTION: (Continued) 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 DEX-COOL® coolant. If you use an improper coolant Notice: mixture, 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 coolant needs to be added more than four times a year, have your dealer check the cooling system. Notice: If you use extra inhibitors and/or additives in your vehicle’s cooling system, you could damage your vehicle. Use only the proper mixture of the engine coolant listed in this manual for the cooling system. See Recommended Fluids and Lubricants on page 415 for more information. 321 Checking Coolant The coolant recovery tank cap has this symbol on it. See Engine Compartment Overview on page 308 for more information on the location of the coolant recovery tank. The vehicle must be on a level surface when checking the coolant level. When the engine is cold, the coolant level should be at the cold ﬁll line or a little higher. The cold ﬁll line is marked with the same symbol as the coolant recovery tank cap. 322 Adding Coolant If more coolant is needed, add the proper DEX-COOL® coolant mixture at the coolant recovery tank, but be careful not to spill it. If the coolant recovery tank is completely empty, add coolant to the cooling system through the coolant ﬁll neck on the engine. See Engine Overheating on page 323. {CAUTION: Turning the radiator pressure cap when the engine and radiator are hot can allow steam and scalding liquids to blow out and burn you badly. With the coolant recovery tank, you will almost never have to add coolant at the radiator. Never turn the radiator pressure cap — even a little — when the engine and radiator are hot. Engine Overheating There is a coolant temperature gage and a warning light on the instrument panel that indicate an overheated engine condition. See Engine Coolant Temperature Gage on page 180 and Engine Coolant Temperature Warning Light on page 179. In addition, you will ﬁnd an ENGINE OVERHEATED IDLE ENGINE and an ENGINE OVERHEATED STOP ENGINE message displayed on the vehicle’s Driver Information Center (DIC). See DIC Warnings and Messages on page 195 for more information. {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. Occasionally check the coolant level in the radiator. For information on how to add coolant to the radiator, see Cooling System on page 326. Pressure Cap Notice: installed, coolant loss and possible engine damage may occur. Be sure the cap is properly and tightly secured. See Engine Compartment Overview on page 308 for more information on location. If the pressure cap is not tightly 323 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. 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 the vehicles 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 on page 325 for information on driving to a safe place in an emergency. 324 If your engine catches ﬁre because Notice: 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 on page 325 for information on driving to a safe place in an emergency. If No Steam Is Coming From Your Engine An overheat warning can indicate a serious problem. 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: (cid:127) Climb a long hill on a hot day. (cid:127) Stop after high-speed driving. (cid:127) Idle for long periods in traffic. (cid:127) Tow a trailer. If an overheat warning occurs without any 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. Set the heater at the highest setting and the fan at the highest speed and open the windows as necessary. If the overheat warning no longer exists, the vehicle can be driven. Just to be safe, drive slower for about 10 minutes. If the warning does not come back on, the vehicle can be driven normally. If the warning continues, and you have not stopped, pull over, stop, and park the vehicle right away. If there is still no sign of steam, idle the engine for three minutes while parked. If the warning is still there, turn off the engine and get everyone out of the vehicle until it cools down. Also, see “Overheated Engine Protection Operating Mode” later in this section. You may decide not to lift the hood but to get service help right away. Overheated Engine Protection Operating Mode This emergency operating mode allows your vehicle to be driven to a safe place in an emergency situation. If an overheated engine condition exists, an overheat protection mode which alternates ﬁring groups of cylinders helps prevent engine damage. In this mode, you will notice a signiﬁcant loss in power and engine performance. The coolant temperature gage will indicate an overheat condition exists. Driving extended miles (km) and/or 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 system. See Engine Oil on page 311. 325 Cooling System When you decide it is safe to lift the hood, this is what you will see: 5.3L V8 Engine A. Pressure Cap B. Electric Engine Cooling Fans C. Coolant Recovery Tank 3.5L V6 Engine A. Coolant Recovery Tank B. Pressure Cap C. Electric Engine Cooling Fans 326 {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. When the engine is cold, the coolant level should be at or above the cold ﬁll line on the coolant recovery tank. To check the coolant level, look for the cold ﬁll line on the side of the coolant recovery tank that faces the engine. If the level is not correct, there may be a leak at the pressure cap or in the radiator hoses, heater hoses, radiator, water pump, or somewhere else in the cooling system. If the coolant inside the coolant recovery tank is boiling, do not do anything else until it cools down. The vehicle should be parked on a level surface. If your vehicle has the 3.5L V6 engine, the coolant recovery tank is located in the rear of the engine compartment on the passenger’s side of the vehicle. If your vehicle has the 5.3L V8 engine, the coolant recovery tank is located in the rear of the engine compartment on the driver’s side of the vehicle. See Engine Compartment Overview on page 308. {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. 327 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, the fans should be running. If the fans are not running, your vehicle needs service. Notice: Engine damage from running your engine without coolant is not covered by your warranty. See Overheated Engine Protection Operating Mode on page 325 for information on driving to a safe place in an emergency. Notice: Using coolant other than DEX-COOL® may cause premature engine, heater core, or radiator corrosion. In addition, the engine coolant could require changing sooner, at 30,000 miles (50 000 km) or 24 months, whichever occurs ﬁrst. Any repairs would not be covered by your warranty. Always use DEX-COOL® (silicate-free) coolant in your vehicle. How to Add Coolant to the Coolant Recovery Tank {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 DEX-COOL® coolant. 328 If you have not found a problem yet, but the coolant level is not at the cold ﬁll line, add a 50/50 mixture of clean, drinkable water and DEX-COOL® engine coolant at the coolant recovery tank. See Engine Coolant on page 320 for more information. Notice: crack the engine, radiator, heater core and other parts. Use the recommended coolant and the proper coolant mixture. In cold weather, water can freeze and {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 the coolant level in the coolant recovery tank is at the cold ﬁll line, start the vehicle. If the overheat warning continues, there is one more thing you can try. Add the proper coolant mixture directly to the cooling system through the coolant ﬁll neck on the engine, but be sure the system is cool before you do it. {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 radiator pressure cap — even a little — they can come out at high speed. Never turn the cap when the cooling system, including the radiator pressure cap, is hot. Wait for the cooling system and radiator pressure cap to cool if you ever have to turn the pressure cap. 329 How to Add Coolant to the Cooling System Notice: Your engine has a speciﬁc cooling system drain and ﬁll procedure. Failure to follow this procedure could cause your engine to overheat and be severely damaged. If your engine’s cooling system needs to be drained and re-ﬁlled, please see your dealer. 1. Remove the pressure cap when the cooling system, including the pressure cap and upper radiator hose is no longer hot. Turn the pressure cap slowly counterclockwise. If you hear a hiss, wait for that to stop. A hiss means that there is still some pressure left. 2. Then keep turning the pressure cap and remove it. 330 {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. 3. Fill the cooling system with the proper DEX-COOL® coolant mixture, up to the base of the ﬁller neck. See Engine Coolant on page 320 for more information about the proper coolant mixture. 4. Rinse or wipe any spilled coolant from the engine and the compartment. 5. Then ﬁll the coolant recovery tank to the cold ﬁll line. 6. Install the coolant recovery tank cap and the pressure cap. After a day or two of driving, when the engine is cold, check the coolant level in the recovery tank. If it is low, reﬁll it to the cold ﬁll line. If the coolant in the recovery tank is constantly low, you should have a dealership service department inspect the vehicle for leaks. Power Steering Fluid The power steering ﬂuid reservoir is located toward the rear of the engine compartment on the passenger’s side of the vehicle. See Engine Compartment Overview on page 308 for reservoir location. 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. How to Check Power Steering Fluid To check the power steering ﬂuid, do the following: 1. Turn the key off and let the engine compartment cool down. 2. Wipe the cap and the top of the reservoir clean. 3. Unscrew the cap and wipe the dipstick with a clean rag. 4. Replace the cap and completely tighten it. 5. Remove the cap again and look at the ﬂuid level on the dipstick. The ﬂuid level should be somewhere within the cross-hatched area on the dipstick. If the ﬂuid is at the ADD mark, you should add ﬂuid. What to Use To determine what kind of ﬂuid to use, see Recommended Fluids and Lubricants on page 415. Always use the proper ﬂuid. Failure to use the proper ﬂuid can cause leaks and damage hoses and seals. 331 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 A WASHER FLUID LOW ADD FLUID message will be displayed on the Driver Information Center (DIC) when you need to add windshield washer ﬂuid to your vehicle. See DIC Warnings and Messages on page 195 for more information. Open the cap with the washer symbol on it. Add washer ﬂuid until the tank is full. 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. (cid:127) 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. See Engine Compartment Overview on page 308 for more information on location. 332 Brakes Brake Fluid Your brake master cylinder reservoir is ﬁlled with DOT-3 brake ﬂuid. See Engine Compartment Overview on page 308 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 system. If it is, you should have your brake 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 your vehicle has 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. See Brake System Warning Light on page 177. 333 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 Recommended Fluids and Lubricants on page 415. 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 the brake system, the 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 the 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 Washing Your Vehicle on page 389. (cid:127) 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. 334 {CAUTION: The brake wear warning sound means that soon the 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. Brake linings should always be replaced as complete axle sets. 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. 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. 335 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. We recommend an ACDelco® replacement battery. See Engine Compartment Overview on page 308 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. 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 337 for tips on working around a battery without getting hurt. 336 Jump Starting If your vehicle’s 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. {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 (cid:127) They contain enough electricity to or 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 Notice: costly 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. If the other vehicle’s system is not Notice: a 12-volt 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. 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. 337 To uncover the remote positive (+) terminal, remove the fuse block cover. You should always use the remote positive (+) terminal instead of the positive (+) terminal on the battery. {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. Notice: If you leave your radio or other accessories 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 outlets. 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! 4. Open the hoods and locate the batteries. Find the positive (+) and negative (−) terminal locations on each vehicle. You will not need to access your battery for jump starting. Your vehicle has a remote positive (+) jump starting terminal for that purpose. The remote positive (+) terminal is located in the engine compartment on the passenger’s side of the vehicle, on the underhood fuse block. See Engine Compartment Overview on page 308 for more information on location. 338 {CAUTION: {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 do not, 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. 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 basic 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. 339 6. Connect the red positive (+) cable to the positive (+) terminal location of the vehicle with 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 location of the vehicle with the good battery. Use a remote positive (+) terminal if the vehicle has one. 8. Now connect the black negative (−) cable to the negative (−) terminal location of the vehicle with 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. 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 Notice: or 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. 340 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 fuse block cover to its original position.

However, 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, it is recommend that you take the vehicle to your dealer for service.
