You will receive genuine Saturn parts and Saturn-trained and supported service people. Genuine Saturn parts have one of these marks. Accessories and Modiﬁcations When non-dealer/non-retailer accessories are added 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 antilock brakes, traction control and stability control. Some of these accessories could 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/retailer can accessorize your vehicle using genuine GM Accessories. When you go to your GM dealer/retailer and ask for GM Accessories, you will know that GM-trained and supported service technicians will perform the work using genuine GM Accessories. Also, see Adding Equipment to Your Airbag-Equipped Vehicle on page 1-70. 5-3 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:129) Be sure you have sufficient knowledge, experience, the proper replacement parts, and tools before you attempt any vehicle maintenance task. (cid:129) 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. 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. California Perchlorate Materials Requirements Certain types of automotive applications, such as airbag initiators, seat belt pretensioners, and lithium batteries contained in remote keyless entry transmitters, may contain perchlorate materials. Special handling may be necessary. For additional information, see www.dtsc.ca.gov/hazardouswaste/perchlorate. 5-4 Fuel Use of the recommended fuel is an important part of the proper maintenance of your vehicle. To help keep the engine clean and maintain optimum vehicle performance, we recommend the use of gasoline advertised as TOP TIER Detergent Gasoline. The 8th digit of the Vehicle Identiﬁcation Number (VIN) shows the code letter or number that identiﬁes your vehicle’s engine. The VIN is at the top left of the instrument panel. See Vehicle Identiﬁcation Number (VIN) on page 5-93. If you want to do some of your own service work, you should 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 7-16. Your vehicle has an airbag system. Before attempting to do your own service work, see Servicing Your Airbag-Equipped Vehicle on page 1-70. 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 6-16. Adding Equipment to the Outside of the Vehicle Things you might add to the outside of your vehicle can affect the airﬂow around it. This can cause wind noise and can affect fuel economy and windshield washer performance. Check with your dealer/retailer before adding equipment to the outside of your vehicle. 5-5 Gasoline Octane If your vehicle has the 2.4L L4 engine (VIN Code B) or the 3.5L V6 engine (VIN Code N), use regular unleaded gasoline with a posted octane rating of 87 or higher. If the octane rating is less than 87, you might 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, the engine needs service. If your vehicle has the 3.6L V6 engine (VIN Code 7), use regular unleaded gasoline with a posted octane rating of 87 or higher. For best performance or trailer towing, you could choose to use middle grade 89 octane unleaded gasoline. If the octane rating is less than 87, you might 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, the engine needs service. Gasoline Speciﬁcations At a minimum, gasoline should meet ASTM speciﬁcation D 4814 in the United States or CAN/CGSB-3.5 or 3.511 in Canada. Some gasolines contain an octane-enhancing additive called methylcyclopentadienyl manganese tricarbonyl (MMT). We recommend against the use of gasolines containing MMT. See Additives on page 5-7 for additional information. 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 might be affected. The malfunction indicator lamp could turn on and your vehicle might fail a smog-check test. See Malfunction Indicator Lamp on page 3-40. If this occurs, return to your authorized dealer/retailer for diagnosis. If it is determined that the condition is caused by the type of fuel used, repairs might not be covered by the vehicle warranty. 5-6 Additives To provide cleaner air, all gasolines in the United States are now required to contain additives that help prevent engine and fuel system deposits from forming, allowing the emission control system to work properly. In most cases, you should not have to add anything to the 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/retailer has additives that will help correct and prevent most deposit-related problems. Gasolines containing oxygenates, such as ethers and ethanol, and reformulated gasolines might be available in your area. We recommend 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. Notice: Your vehicle was not designed for fuel that contains methanol. Do not use fuel containing methanol. It can corrode metal parts in the fuel system and also damage plastic and rubber parts. That damage would not be covered under your warranty. Some gasolines that are not reformulated for low emissions can contain an octane-enhancing additive called methylcyclopentadienyl manganese tricarbonyl (MMT); ask the attendant where you buy gasoline whether the fuel contains MMT. We recommend against the use of such gasolines. Fuels containing MMT can reduce the life of spark plugs and the performance of the emission control system could be affected. The malfunction indicator lamp might turn on. If this occurs, return to your dealer/retailer for service. Fuels in Foreign Countries If you plan on driving in another country outside the United States or Canada, the proper fuel might 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. 5-7 The fuel door is located on the passenger side of the vehicle. To open the fuel door, apply pressure on the center of the rear edge of the fuel door and it will pop open. 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. Do not use cellular phones. 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. Do not re-enter the vehicle while pumping fuel. Keep children away from the fuel pump; never let children pump fuel. 5-8 To remove the tethered fuel cap, turn it slowly counterclockwise. While refueling, hang the tethered fuel cap from the hook on the fuel door. { CAUTION: Fuel can spray out on you if you open the fuel cap too quickly. If you spill fuel and then something ignites it, you could be badly burned. 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 the fuel before removing the nozzle. Clean fuel from painted surfaces as soon as possible. See Washing Your Vehicle on page 5-88. 5-9 When replacing the fuel cap, turn it to the 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 3-40. If your vehicle has a Driver Information Center (DIC), the CHECK GAS CAP message displays if the fuel cap is not properly installed. { 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/ retailer 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 3-40. 5-10 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 fuel vapor. You can be badly burned and your vehicle damaged if this occurs. To help avoid injury to you and others: (cid:129) Dispense fuel only into approved containers. (cid:129) 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) CAUTION: (Continued) (cid:129) 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:129) Do not smoke while pumping fuel. (cid:129) Do not use a cellular phone while pumping fuel. 5-11 Checking Things Under the Hood Hood Release To open the hood, do the following: 1. Pull the hood release handle with this symbol on it. It is located inside the vehicle to the left of the steering column. { 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. 5-12 2. Then go to the front of the vehicle and push the secondary hood release handle toward the driver side of the vehicle. 3. Lift the hood. 4. After the hood is slightly lifted, it will continue to open to the full position. Before closing the hood, be sure all the ﬁller caps are on properly. Lower the hood until the lifting force of the strut is reduced, then release the hood to latch fully. Check to make sure the hood is closed and repeat the process if necessary. 5-13 Engine Compartment Overview When you open the hood on the 2.4L L4 engine, this is what you see: 5-14 A.

See “Adding Washer Fluid” under Windshield Washer Fluid on page 5-38. 5-19 Engine Oil 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 5-14 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. When to Add Engine Oil 2.4L L4 Engine 3.5L V6 Engine 5-20 See Engine Compartment Overview on page 5-14 for the location of the engine oil ﬁll cap. 3.6LV6 Engine If the oil is below the cross-hatched area at the tip of the dipstick, add at least one quart/liter of the recommended oil. This section explains what kind of oil to use. For engine oil crankcase capacity, see Capacities and Speciﬁcations on page 5-104. Notice: Do not add too much oil. If the engine has so much oil that the oil level gets above the upper mark that shows the proper operating range, the engine could be damaged. Add enough oil to put the level somewhere in the proper operating range. Push the dipstick all the way back in when you are through. 5-21 What Kind of Engine Oil to Use Look for three things: (cid:129) GM6094M Use only an oil that meets GM Standard GM6094M. (cid:129) SAE 5W-30 SAE 5W-30 is best for the vehicle. If you are in an area of extreme cold, where the temperature falls below −20°F (−29°C), use either an SAE 5W-30 5-22 synthetic oil or an SAE 0W-30 oil. Both provide easier cold starting and better protection for the engine at extremely low temperatures. These numbers on an oil container show its viscosity, or thickness. Do not use other viscosity oils such as SAE 20W-50. (cid:129) American Petroleum Institute (API) starburst symbol Oils meeting these requirements should have the starburst symbol on the container. This symbol indicates that the oil has been certiﬁed by the American Petroleum Institute (API). 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. 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 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. When the system has calculated that oil life has been diminished, it will indicate that an oil change is necessary. A CHANGE OIL SOON message will come on. See DIC Warnings and Messages on page 3-47. Change the 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 might not indicate that an oil change is necessary for over a year. However, the engine oil and ﬁlter must be changed at least once a year and at this time the system must be reset. Your dealer/retailer has trained service people who will perform this work using genuine parts and reset the system. It is also important to check the oil regularly and keep it at the proper level. If the system is ever reset accidentally, you must change the 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. 5-23 How to Reset the Engine Oil Life System The Engine Oil Life System calculates when to change the engine oil and ﬁlter based on vehicle use. Whenever the oil is changed, reset the system so it can calculate when the next oil change is required. If a situation occurs where you change the oil prior to a CHANGE OIL SOON message being turned on, reset the system. After changing the engine oil and ﬁlter, the system must be reset. To reset the oil life system: 1. Turn the ignition key to ON/RUN with the engine off. 2. Fully press and release the accelerator pedal three times within ﬁve seconds. If the message is not displayed, the system is reset. If the CHANGE 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 can 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. Recycle it by taking it to a place that collects used oil. 5-24 Engine Air Cleaner/Filter See Engine Compartment Overview on page 5-14 for the location of the engine air cleaner/ﬁlter. 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 (80 000 km) interval. See Scheduled Maintenance on page 6-4 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. To inspect or replace the engine air cleaner/ﬁlter, do the following: 1. Remove the spring clamps that hold the cover on. 2. Lift off the cover. 5-25 { 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. Notice: If the air cleaner/ﬁlter is off, a backﬁre can cause a damaging engine ﬁre. And, dirt can easily get into your engine, which will damage it. Always have the air cleaner/ﬁlter in place when you are driving. 3. Inspect or replace the engine air cleaner/ﬁlter. 4. Align the ﬁlter correctly using the alignment tab. 5. Install the cover by guiding the tabs on the rim of the top cover into the bottom hinges and turn the cover down to close it. 6. The spring clips will engage easily, if the cover is properly seated. 5-26 Automatic Transmission Fluid It is not necessary to check the transmission ﬂuid level. A transmission ﬂuid leak is the only reason for ﬂuid loss. If a leak occurs, take your vehicle to the dealer/retailer and have it repaired as soon as possible. Change the ﬂuid and ﬁlter at the intervals listed in Additional Required Services on page 6-6, and be sure to use the transmission ﬂuid listed in Recommended Fluids and Lubricants on page 6-12. Notice: Use of the incorrect automatic transmission ﬂuid may damage your vehicle, and the damages may not be covered by your warranty. Always use the automatic transmission ﬂuid listed in Recommended Fluids and Lubricants on page 6-12. For the 2.4L, 3.5L and 3.6L engines, the transmission ﬂuid will not reach the end of the dipstick unless the transmission is at operating temperature. If you need to check the transmission ﬂuid level, please take your vehicle to your dealer/retailer. 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, see Engine Overheating on page 5-30. A 50/50 mixture of clean, drinkable water and DEX-COOL® coolant will: (cid:129) Give freezing protection down to −34°F (−37°C). (cid:129) Give boiling protection up to 265°F (129°C). (cid:129) Protect against rust and corrosion. (cid:129) Help keep the proper engine temperature. Let the warning lights and gages work as they should. Notice: Using coolant other than DEX-COOL® can 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 the vehicle warranty. Always use DEX-COOL® (silicate-free) coolant in the vehicle. 5-27 (cid:129) Notice: If an improper coolant mixture is used, the engine could overheat and be badly damaged. The repair cost would not be covered by the vehicle 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/retailer check your cooling system. Notice: in the vehicle’s cooling system, the vehicle could be damaged. Use only the proper mixture of the engine coolant listed in this manual for the cooling system. See Recommended Fluids and Lubricants on page 6-12 for more information. If extra inhibitors and/or additives are used 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 the cooling system can be dangerous. Plain water, or some other liquid such as alcohol, can boil before the proper coolant mixture will. The vehicle’s coolant warning system is set for the proper coolant mixture. With plain water or the wrong mixture, the engine could get too hot but would not get the overheat warning. The engine could catch ﬁre and you or others could be burned. Use a 50/50 mixture of clean, drinkable water and DEX-COOL® coolant. 5-28 Checking Coolant The engine coolant surge tank is located in the rear of the engine compartment. See Engine Compartment Overview on page 5-14 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 at the FULL COLD mark or slightly higher. 5-29 Adding Coolant If you need more coolant, add the proper DEX-COOL® 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 Engine Overheating on page 5-30 and Cooling System on page 5-33. { CAUTION: You can be burned if you spill coolant on hot engine parts. Coolant contains eythylene 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 and fully seated. If the pressure cap is not tightly installed, Pressure Cap Notice: coolant loss and possible engine damage may occur. Be sure the cap is properly and tightly secured. See Engine Compartment Overview on page 5-14 for more information on location. Engine Overheating You will ﬁnd an engine coolant temperature gage as well as an engine coolant temperature warning light on your vehicle’s instrument panel cluster. See Engine Coolant Temperature Gage on page 3-39 and Engine Coolant Temperature Warning Light on page 3-38. 5-30 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 5-32 for information on driving to a safe place in an emergency. If the engine catches ﬁre while driving with Notice: no coolant, the vehicle can be badly damaged. The costly repairs would not be covered by the vehicle warranty. See Overheated Engine Protection Operating Mode on page 5-32 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:129) Climb a long hill on a hot day. (cid:129) Stop after high-speed driving. Idle for long periods in traffic. Tow a trailer. 5-31 (cid:129) (cid:129) 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 N (Neutral) while stopped. If it is safe to do so, pull off the road, shift to P (Park) or N (NEUTRAL) and let the engine idle. 2. Turn on your heater to full hot at the highest fan speed and open the windows as necessary. 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, pull over, stop, and park your vehicle right away. If there is still no sign of steam, 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 might 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 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 5-20. 5-32 Cooling System When you decide it is safe to lift the hood, this is what you see: { CAUTION: An electric engine cooling fan under the hood can start up even when the engine is not running and can cause injury. 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. 3.5L V6 Engine shown, 2.4L L4, 3.6L V6 Engines similar A. Engine Cooling Fans B. Engine Coolant Surge Tank C. Pressure Cap 5-33 The coolant level should be at or above the FULL COLD mark on the coolant surge tank. 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. { 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 fans are running. If the engine is overheating, both fans should be running. If they are not, your vehicle needs service. Notice: Engine damage from running the engine without coolant is not covered by the warranty. 5-34 Notice: Using coolant other than DEX-COOL® can 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 the vehicle warranty. Always use DEX-COOL® (silicate-free) coolant in the vehicle. 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 the 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 at or above the FULL COLD mark, add a 50/50 mixture of clean, drinkable water and DEX-COOL® 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 5-27 for more information. 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 the cooling system can be dangerous. Plain water, or some other liquid such as alcohol, can boil before the proper coolant mixture will. The vehicle’s coolant warning system is set for the proper coolant mixture. With plain water or the wrong mixture, the engine could get too hot but you would not get the overheat warning. The engine could catch ﬁre and you or others could be burned. Use a 50/50 mixture of clean, drinkable water and DEX-COOL® 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. 5-35 { CAUTION: You can be burned if you spill coolant on hot engine parts. Coolant contains eythylene glycol and it will burn if the engine parts are hot enough. Do not spill coolant on a hot engine. 1. 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 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. 3. Fill the coolant surge tank with the proper mixture, to the FULL COLD mark. Wait about ﬁve minutes, then check to see if the level is below the mark. If the level is below the FULL COLD mark, add additional coolant to bring the level up to the mark. Repeat this procedure until the level remains constant at the FULL COLD mark for at least ﬁve minutes. 4. With the coolant surge tank pressure cap off, start the engine and let it run until you can feel the upper radiator hose getting hot. Watch out for the engine cooling fans. By this time, the coolant level inside the coolant surge tank might be lower. If the level is lower than the FULL COLD mark, add more of the proper mixture to the coolant surge tank until the level reaches the FULL COLD mark. 5. Then replace the pressure cap. Be sure the pressure cap is hand-tight and fully seated. 5-36 Power Steering Fluid See Engine Compartment Overview on page 5-14 for reservoir location. When to Check Power Steering Fluid Power steering ﬂuid is used in all vehicles with V6 engines. Vehicles with the 4-cylinder engine have electric power steering and do not use power steering ﬂuid. It is not necessary to regularly check power steering ﬂuid unless a leak is suspected in the system, or an unusual noise is heard. 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. If your vehicle has the 3.5L V6 engine, the ﬂuid level should be between the ADD and HOT marks when the engine is cold, and at the HOT mark when the engine is hot. If the ﬂuid is at the ADD mark when the engine is cold or hot, power steering ﬂuid should be added. If your vehicle has the 3.6L V6 engine, the ﬂuid level should be between the MIN (Minimum) and MAX (Maximum) marks when the engine is cold, and at the MAX mark when the engine is hot. If the ﬂuid is at the MIN mark when the engine is cold or hot, power steering ﬂuid should be added. The ﬂuid level should be within the crosshatch area on the dipstick. If the ﬂuid is at or below the ADD or MIN mark on the dipstick, add just enough ﬂuid to bring the level within the crosshatch area. 5-37 What to Use To determine what kind of ﬂuid to use, see Recommended Fluids and Lubricants on page 6-12. Always use the proper ﬂuid. Notice: Use of the incorrect ﬂuid may damage your vehicle and the damages may not be covered by your warranty. Always use the correct ﬂuid listed in Recommended Fluids and Lubricants on page 6-12. 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 When the windshield washer ﬂuid reservoir is low, a LOW WASHER FLUID message displays on the Driver Information Center (DIC). See DIC Warnings and Messages on page 3-47 for more information. 5-38 Open the cap with the washer symbol on it. Add washer ﬂuid until the tank is full. See Engine Compartment Overview on page 5-14 for reservoir location. Notice: (cid:129) When using concentrated washer ﬂuid, follow the manufacturer’s instructions for adding water. (cid:129) 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 the washer ﬂuid tank only three-quarters full when it is very cold. This allows for ﬂuid expansion if freezing occurs, which could damage the tank if it is completely full. (cid:129) Do not use engine coolant (antifreeze) in your windshield washer. It can damage the vehicle’s windshield washer system and paint. (cid:129) Brakes Brake Fluid The brake master cylinder reservoir is ﬁlled with DOT-3 brake ﬂuid. See Engine Compartment Overview on page 5-14 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 hydraulic system. If it is, have the brake hydraulic system ﬁxed, since a leak means that sooner or later the brakes will not work well. Do not top off the brake ﬂuid. Adding brake ﬂuid will not correct a leak. If ﬂuid is added when the linings are worn, there will be too much ﬂuid when new brake linings are installed. 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 the brake ﬂuid falls to a low level, the BRAKE FLUID message in the Driver Information Center (DIC) displays. See DIC Warnings and Messages on page 3-47. 5-39 What to Add Use only new DOT-3 brake ﬂuid from a sealed container. See Recommended Fluids and Lubricants on page 6-12. Always clean the brake ﬂuid reservoir cap and the area around the cap before removing it. This helps keep dirt from entering the reservoir. { CAUTION: With the wrong kind of ﬂuid in the brake hydraulic system, the brakes might not work well. This could cause a crash. Always use the proper brake ﬂuid. Notice: (cid:129) Using the wrong ﬂuid can badly damage brake hydraulic system parts. For example, just a few drops of mineral-based oil, such as engine oil, in the brake hydraulic system can damage brake hydraulic 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 5-88. Brake Wear Your vehicle has 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 can come and go or be heard all the time your vehicle is moving, except when you are pushing on the brake pedal ﬁrmly. 5-40 (cid:129) { 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 can cause a brake squeal when the brakes are ﬁrst applied or lightly applied. This does not mean something is wrong with the 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 torque speciﬁcations in Capacities and Speciﬁcations on page 5-104. Brake linings should always be replaced as complete axle sets. Brake Pedal Travel See your dealer/retailer 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 that brake service might be required. Brake Adjustment Every time you apply the brakes, with or without the vehicle moving, the 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 brake parts. When you replace parts of the braking system — for example, when the brake linings wear down and you need new ones put in — be sure you get new approved replacement parts. If you do not, the brakes might not work properly. For example, if someone puts in brake linings that are wrong for your vehicle, the balance between the 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. 5-41 Battery Your vehicle has a maintenance free battery. When it is time for a new battery, see your dealer/retailer for one that has the replacement number shown on the original battery’s label. See Engine Compartment Overview on page 5-14 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 { 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 5-43 for tips on working around a battery without getting hurt. Infrequent Usage: If you drive your vehicle infrequently, remove the black, negative (−) cable from the battery. This will help keep the battery from running down. Extended Storage: For extended storage of your vehicle, remove the black, negative (−) cable from the battery or use a battery trickle charger. This will help maintain the charge of the battery over an extended period of time. 5-42 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. { CAUTION: Batteries can hurt you. They can be dangerous because: (cid:129) They contain acid that can burn you. (cid:129) They contain gas that can explode or ignite. (cid:129) They contain enough electricity to 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. 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. 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 transmission in P (Park) or a manual transmission 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! 5-43 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. The negative (–) terminal is located under a black tethered cap on the battery. See Engine Compartment Overview on page 5-14 for more information on location. Flip the caps up to access the positive (+) and negative (–) terminals. { 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. 5-44 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. { 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. 5-45 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. 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. 5-46 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 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. Bulb Replacement For the proper type of replacement bulbs, see Replacement Bulbs on page 5-50. For any bulb changing procedure not listed in this section, contact your dealer/retailer. 3. Disconnect the red positive (+) cable from the vehicle with the good battery. Halogen Bulbs 4. Disconnect the red positive (+) cable from the other vehicle. 5. Return the caps over the positive (+) and negative (–) terminals to their original positions. Headlamp Aiming Headlamp aim has been preset at the factory and should need no further adjustment. However, if your vehicle is damaged in a crash, the headlamp aim may be affected. Aim adjustment to the low-beam headlamps may be necessary if oncoming drivers ﬂash their high-beam headlamps at you (for vertical aim). If the headlamps need to be re-aimed, it is recommended that you take the vehicle to your dealer/retailer for service. { 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. 5-47 Taillamps, Turn Signal, Sidemarker, Stoplamps and Back-up Lamps To replace a sidemarker lamp, turn signal lamp, or a back-up lamp: 1.

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 vehicle Warranty booklet for details. { CAUTION: Poorly maintained and improperly used tires are dangerous. (cid:129) Overloading your vehicle’s tires can cause overheating as a result of too much ﬂexing. You could have an air-out and a serious accident. See Loading the Vehicle on page 4-24. CAUTION: (Continued) CAUTION: (Continued) (cid:129) 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 vehicle’s tires are cold. See Inﬂation - Tire Pressure on page 5-58. (cid:129) 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:129) Worn, old tires can cause accidents. If the tire’s tread is badly worn, or if your vehicle’s tires have been damaged, replace them. 5-51 Tire Sidewall Labeling Useful information about a tire is molded into its sidewall. The examples below show a typical passenger vehicle tire and a compact spare tire sidewall. Passenger (P-Metric) Tire Example 5-52 (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. See the “Tire Size” illustration later in this section for more detail. (B) TPC Spec (Tire Performance Criteria Speciﬁcation): Original equipment tires designed to GM’s speciﬁc tire performance criteria have a TPC speciﬁcation code molded onto the sidewall. GM’s TPC speciﬁcations meet or exceed all federal safety guidelines. (C) DOT (Department of Transportation): The Department of Transportation (DOT) code indicates that the tire is in compliance with the U.S. Department of Transportation Motor Vehicle Safety Standards. (D) Tire Identiﬁcation Number (TIN): The letters and numbers following DOT (Department of Transportation) code is the Tire Identiﬁcation Number (TIN). The TIN shows the manufacturer and plant code, tire size, and date the tire was manufactured. The TIN is molded onto both sides of the tire, although only one side may have the date of manufacture. (E) Tire Ply Material: The type of cord and number of plies in the sidewall and under the tread. (F) Uniform Tire Quality Grading (UTQG): Tire manufacturers are required to grade tires based on three performance factors: treadwear, traction, and temperature resistance. For more information see Uniform Tire Quality Grading on page 5-69. (G) Maximum Cold Inﬂation Load Limit: Maximum load that can be carried and the maximum pressure needed to support that load. Compact Spare Tire Example (A) Temporary Use Only: The compact spare tire or temporary use tire has a tread life of approximately 3,000 miles (5 000 km) and should not be driven at speeds over 65 mph (105 km/h). The compact spare tire is for emergency use when a regular road tire has lost air and gone ﬂat. If your vehicle has a compact spare tire, see Compact Spare Tire on page 5-84 and If a Tire Goes Flat on page 5-73. (B) Tire Ply Material: The type of cord and number of plies in the sidewall and under the tread. (C) Tire Identiﬁcation Number (TIN): The letters and numbers following the DOT (Department of Transportation) code is the Tire Identiﬁcation Number (TIN). The TIN shows the manufacturer and plant code, tire size, and date the tire was manufactured. The TIN is molded onto both sides of the tire, although only one side may have the date of manufacture. (D) Maximum Cold Inﬂation Load Limit: Maximum load that can be carried and the maximum pressure needed to support that load. (E) Tire Inﬂation: The temporary use tire or compact spare tire should be inﬂated to 60 psi (420 kPa).

The load index represents the load carry capacity a tire is certiﬁed to carry. The load index can range from 1 to 279. The speed rating is the maximum speed a tire is certiﬁed to carry a load. Speed ratings range from A to Z. Tire Terminology and Deﬁnitions Air Pressure: The amount of air inside the tire pressing outward on each square inch of the tire. Air pressure is expressed in pounds per square inch (psi) or kilopascal (kPa). Accessory Weight: This means the combined weight of optional accessories. Some examples of optional accessories are, automatic transmission, power steering, power brakes, power windows, power seats, and air conditioning. Aspect Ratio: The relationship of a tire’s height to its width. Belt: A rubber coated layer of cords that is located between the plies and the tread. Cords may be made from steel or other reinforcing materials. Bead: The tire bead contains steel wires wrapped by steel cords that hold the tire onto the rim. Bias Ply Tire: A pneumatic tire in which the plies are laid at alternate angles less than 90 degrees to the centerline of the tread. Cold Tire Pressure: The amount of air pressure in a tire, measured in pounds per square inch (psi) or kilopascals (kPa) before a tire has built up heat from driving. See Inﬂation - Tire Pressure on page 5-58. Curb Weight: The weight of a motor vehicle with standard and optional equipment including the maximum capacity of fuel, oil, and coolant, but without passengers and cargo. DOT Markings: A code molded into the sidewall of a tire signifying that the tire is in compliance with the U.S. Department of Transportation (DOT) motor vehicle safety standards. The DOT code includes the Tire Identiﬁcation Number (TIN), an alphanumeric designator which can also identify the tire manufacturer, production plant, brand, and date of production. GVWR: Gross Vehicle Weight Rating. See Loading the Vehicle on page 4-24. GAWR FRT: Gross Axle Weight Rating for the front axle. See Loading the Vehicle on page 4-24. 5-55 GAWR RR: Gross Axle Weight Rating for the rear axle. See Loading the Vehicle on page 4-24.

Outward Facing Sidewall: The side of an asymmetrical tire that has a particular side that faces outward when mounted on a vehicle. The side of the tire that contains a whitewall, bears white lettering, or bears manufacturer, brand, and/or model name molding that is higher or deeper than the same moldings on the other sidewall of the tire. Passenger (P-Metric) Tire: A tire used on passenger cars and some light duty trucks and multipurpose vehicles. Recommended Inﬂation Pressure: Vehicle manufacturer’s recommended tire inﬂation pressure as shown on the tire placard. See Inﬂation - Tire Pressure on page 5-58 and Loading the Vehicle on page 4-24. 5-56 Radial Ply Tire: A pneumatic tire in which the ply cords that extend to the beads are laid at 90 degrees to the centerline of the tread. Rim: A metal support for a tire and upon which the tire beads are seated. Sidewall: The portion of a tire between the tread and the bead. Speed Rating: An alphanumeric code assigned to a tire indicating the maximum speed at which a tire can operate. Traction: The friction between the tire and the road surface. 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 5-66. 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 5-69. Vehicle Capacity Weight: The number of designated seating positions multiplied by 150 lbs (68 kg) plus the rated cargo load. See Loading the Vehicle on page 4-24. 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 the Vehicle on page 4-24. 5-57 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: (cid:129) Too much ﬂexing (cid:129) Too much heat (cid:129) Tire overloading (cid:129) Premature or irregular wear (cid:129) Poor handling (cid:129) Reduced fuel economy If your tires have too much air (over-inﬂation), you can get the following: (cid:129) Unusual wear (cid:129) Poor handling (cid:129) Rough ride (cid:129) Needless damage from road hazards A vehicle speciﬁc Tire and Loading Information label is attached to your vehicle. 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 the Vehicle on page 4-24. How you load your vehicle affects vehicle handling and ride comfort. Never load your vehicle with more weight than it was designed to carry. 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 5-84. 5-58 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 Pressure Monitor System The Tire Pressure Monitor System (TPMS) uses radio and sensor technology to check tire pressure levels. The TPMS sensors monitor the air pressure in your vehicle’s tires and transmit tire pressure readings to a receiver located in the vehicle. Each tire, including the spare (if provided), should be checked monthly when cold and inﬂated to the inﬂation pressure recommended by the vehicle manufacturer on the vehicle placard or tire inﬂation pressure label. (If your vehicle has tires of a different size than the size indicated on the vehicle placard or tire inﬂation pressure label, you should determine the proper tire inﬂation pressure for those tires.) As an added safety feature, your vehicle has been equipped with a tire pressure monitoring system (TPMS) that illuminates a low tire pressure telltale when one or more of your tires is signiﬁcantly under-inﬂated. Accordingly, when the low tire pressure telltale illuminates, you should stop and check your tires as soon as possible, and inﬂate them to the proper pressure. Driving on a signiﬁcantly under-inﬂated tire causes the tire to overheat and can lead to tire failure. Under-inﬂation also reduces fuel efficiency and tire tread life, and may affect the vehicle’s handling and stopping ability. 5-59 Please note that the TPMS is not a substitute for proper tire maintenance, and it is the driver’s responsibility to maintain correct tire pressure, even if under-inﬂation has not reached the level to trigger illumination of the TPMS low tire pressure telltale. Your vehicle has also been equipped with a TPMS malfunction indicator to indicate when the system is not operating properly. The TPMS malfunction indicator is combined with the low tire pressure telltale. When the system detects a malfunction, the telltale will ﬂash for approximately one minute and then remain continuously illuminated. This sequence will continue upon subsequent vehicle start-ups as long as the malfunction exists. When the malfunction indicator is illuminated, the system may not be able to detect or signal low tire pressure as intended. TPMS malfunctions may occur for a variety of reasons, including the installation of replacement or alternate tires or wheels on the vehicle that prevent the TPMS from functioning properly. Always check the TPMS malfunction telltale after replacing one or more tires or wheels on your vehicle to ensure that the replacement or alternate tires and wheels allow the TPMS to continue to function properly. See Tire Pressure Monitor Operation on page 5-61 for additional information. 5-60 Federal Communications Commission (FCC) and Industry and Science Canada The Tire Pressure Monitor System (TPMS) operates on a radio frequency and complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: 1. This device may not cause harmful interference. 2. This device must accept any interference received, including interference that may cause undesired operation. The TPMS operates on a radio frequency and complies with RSS-210 of Industry and Science Canada. Operation is subject to the following two conditions: 1. This device may not cause interference. 2. This device must accept any interference received, including interference that may cause undesired operation of the device. Changes or modiﬁcations to this system by other than an authorized service facility could void authorization to use this equipment. Tire Pressure Monitor Operation The Tire Pressure Monitor System (TPMS) is designed to warn the driver when a low tire pressure condition exists. TPMS sensors are mounted onto each tire and wheel assembly, excluding the spare tire and wheel assembly. The TPMS sensors monitor the air pressure in the vehicle’s tires and transmits the tire pressure readings to a receiver located in the vehicle. When a low tire pressure condition is detected, the TPMS turns on the low tire pressure warning light located on the instrument panel cluster. At the same time a message to check the pressure in a speciﬁc tire appears on the Driver Information Center (DIC) display. The low tire pressure warning light and the DIC warning message come on at each ignition cycle until the tires are inﬂated to the correct inﬂation pressure. Using the DIC, tire pressure levels can be viewed by the driver. For additional information and details about the DIC operation and displays see DIC Operation and Displays on page 3-45 and DIC Warnings and Messages on page 3-47. The low tire pressure warning light may come on in cool weather when the vehicle is ﬁrst started, and then turn off as you start to drive. This could be an early indicator that the air pressure in the tire(s) are getting low and need to be inﬂated to the proper pressure. A Tire and Loading Information label shows the size of your vehicle’s original equipment tires and the correct inﬂation pressure for your vehicle’s tires when they are cold. See Loading the Vehicle on page 4-24, for an example of the Tire and Loading Information label and its location on your vehicle. Also see Inﬂation - Tire Pressure on page 5-58. Your vehicle’s TPMS system can warn you about a low tire pressure condition but it does not replace normal tire maintenance. See Tire Inspection and Rotation on page 5-64 and Tires on page 5-51. Notice: Liquid tire sealants could damage the Tire Pressure Monitor System (TPMS) sensors. Sensor damage caused by using a tire sealant is not covered by your warranty. Do not use liquid tire sealants. 5-61 (cid:129) One or more TPMS sensors are missing or damaged. The DIC message and the TPMS malfunction light should go off when the TPMS sensors are installed and the sensor matching process is performed successfully. See your dealer/retailer for service. (cid:129) Replacement tires or wheels do not match your vehicle’s original equipment tires or wheels. Tires and wheels other than those recommended for your vehicle could prevent the TPMS from functioning properly. See Buying New Tires on page 5-67. (cid:129) Operating electronic devices or being near facilities using radio wave frequencies similar to the TPMS could cause the TPMS sensors to malfunction. If the TPMS is not functioning it cannot detect or signal a low tire condition. See your dealer/retailer for service if the TPMS malfunction light and DIC message comes on and stays on. TPMS Malfunction Light and Message The TPMS will not function properly if one or more of the TPMS sensors are missing or inoperable. When the system detects a malfunction, the low tire warning light ﬂashes for about one minute and then stays on for the remainder of the ignition cycle. A DIC warning message is also displayed. The low tire warning light and DIC warning message come on at each ignition cycle until the problem is corrected. Some of the conditions that can cause the malfunction light and DIC message to come on are: (cid:129) One of the road tires has been replaced with the spare tire. The spare tire does not have a TPMS sensor. The TPMS malfunction light and DIC message should go off once you re-install the road tire containing the TPMS sensor. The TPMS sensor matching process was started but not completed or not completed successfully after rotating the vehicle’s tires. The DIC message and TPMS malfunction light should go off once the TPMS sensor matching process is performed successfully. See “TPMS Sensor Matching Process” later in this section. 5-62 (cid:129) TPMS Sensor Matching Process Each TPMS sensor has a unique identiﬁcation code. Any time you replace one or more of the TPMS sensors or rotate the vehicle’s tires, the identiﬁcation codes need to be matched to the new tire/wheel location. The sensors are matched, to the tire/wheel locations, in the following order: driver side front tire, passenger side front tire, passenger side rear tire, and driver side rear tire using a TPMS diagnostic tool. See your dealer/retailer for service. The TPMS sensors can also be matched to each tire/wheel position by increasing or decreasing the tire’s air pressure. When increasing the tire’s pressure, do not exceed the maximum inﬂation pressure indicated on the tire’s sidewall. To decrease the tire’s air-pressure use the pointed end of the valve cap, a pencil-style air pressure gage, or a key. You have two minutes to match each tire and wheel position. If it takes longer than two minutes to match any tire and wheel position, the matching process stops and you need to start over. The TPMS matching process is outlined below: 1. Set the parking brake. 2. Turn the ignition switch to ON/RUN with the engine off. 3. Press and hold the Remote Keyless Entry (RKE) transmitter’s LOCK and UNLOCK buttons, at the same time, for about ﬁve seconds to start the TPMS learn mode. The horn sounds twice indicating the TPMS receiver is ready and in learn mode. 4. Start with the driver side front tire. The driver side front turn signal also comes on to indicate that corner’s sensor is ready to be learned. 5. Remove the valve cap from the tire’s valve stem. Activate the TPMS sensor by increasing or decreasing the tire’s air pressure for about eight seconds. The horn chirp, can take up to 30 seconds to sound. It chirps one time and then all the turn signals ﬂash one time to conﬁrm the sensor identiﬁcation code has been matched to the tire/wheel position. 6. The passenger side front turn signal comes on to indicate that corner sensor is ready to be learned. Proceed to the passenger side front tire and repeat the procedure in Step 5. 5-63 7. The passenger side rear turn signal comes on to indicate that corner sensor is ready to be learned. Proceed to the passenger side rear tire and repeat the procedure in Step 5. 8. The driver side rear turn signal comes on to indicate that corner sensor is ready to be learned. Proceed to the driver side rear tire, and repeat the procedure in Step 5. 9. After hearing the single horn chirp for the driver side rear tire, two additional horn chirps sound to indicate the tire learning process is done. Turn the ignition switch to LOCK/OFF. If no tires are learned after entering the TPMS learn mode, or if communication with the receiver stops, or if the time limit has expired, turn the ignition switch to LOCK/OFF and start over beginning with Step 2. 10. Set all four tires to the recommended air pressure level as indicated on the Tire and Loading Information label. 11. Put the valve caps back on the valve stems. Tire Inspection and Rotation We recommend that you regularly inspect your vehicle’s tires, including the spare tire, for signs of wear or damage. See When It Is Time for New Tires on page 5-66 for more information. Tires should be rotated every 5,000 to 8,000 miles (8 000 to 13 000 km). See Scheduled Maintenance on page 6-4. The purpose of a regular tire rotation is to achieve a uniform wear for all tires on the vehicle. This will ensure that your vehicle continues to perform most like it did when the tires were new. Any time you notice unusual wear, rotate the
