system whenever the oil is changed. 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 engine oil light being turned on, reset the system. After changing the engine oil, reset the system: 1. Turn the ignition key to RUN with the


engine off.


2. Fully press and release the accelerator pedal


three times within five seconds. If the change engine oil light is flashing, the system is reset. The light will flash for up to 30 seconds or until the ignition is turned off.


If the light comes on again and stays on for 30 seconds at the next ignition cycle, it did not reset. You will need to reset the system again.

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. 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/retailer, a service station, or a local recycling center for help.


Engine Air Cleaner/Filter See Engine Compartment Overview on page 314
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 (83 000 km) interval. See Scheduled Maintenance on page 420 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.


324


To inspect or replace the engine air cleaner/filter, do the following:


1. Unscrew the clamp on the air duct hose.


2. Disconnect the hose.


325


3. Release the clamps on the side of the air


cleaner assembly.


4. Turn the cover upward to disengage the


cover hinges.


5. Remove the air cleaner cover assembly and


air filter element.


6. Inspect or replace the air filter element.


If the air filter element is dirty, you should replace it. If it is only dusty, it may be cleaned by blowing compressed air through it from the clean side. Make sure you are away from the engine compartment when cleaning the air filter with compressed air.


326


Wipe all dust from inside of the housing and inspect the air cleaner and air outlet duct for cracks, cuts and deterioration. The air outlet duct must be replaced if damaged.


7. Reverse Steps 1 through 5 to reinstall


the engine air cleaner/filter cover and air duct hose.


{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.


Automatic Transaxle Fluid (2.2L L4 Engine) 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 at the intervals listed in Additional Required Services on page 423, and be sure to use the transaxle fluid listed in Recommended Fluids and Lubricants on page 432. How to Check Automatic Transaxle Fluid If your vehicle is equipped with the 2.2L L4
engine, you will have to have this procedure done at your retailer’s service department. 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 432.


327


Automatic Transaxle Fluid (3.5L V6 Engine) 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 at the intervals listed in Additional Required Services on page 423, and be sure to use the transaxle fluid listed in Recommended Fluids and Lubricants on page 432. How to Check Automatic Transaxle Fluid Because this operation can be a little difficult, you may choose to have this done at your retailer’s 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:129) When outside temperatures are


above 90°F (32°C).


(cid:129) At high speed for quite a while.


In heavy traffic — especially in hot weather.


(cid:129) While pulling a trailer. To get the right reading, the fluid should be at normal operating temperature, which is 180°F to 200°F (82°C to 93°C). Get the vehicle warmed up by driving about 15 miles (24 km) when outside temperatures are above 50°F (10°C). If it is colder than 50°F (10°C), you may have to drive longer.


328


(cid:129) Checking the Fluid Level Prepare your vehicle as follows: 1. Park your vehicle on a level place. 2. Warm the engine to normal operating


temperature until the electric radiator fan turns on at least once.


3. With the parking brake applied, place the shift


lever in PARK (P).


4. 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).


Then, turn off the engine and follow these steps: The transaxle fluid dipstick handle is the black loop near the rear of the engine compartment, toward the center. 1. Pull out the dipstick and wipe it with a clean


rag or paper towel.


2. Push it back in all the way, wait three seconds


and then pull it back out again.


3. Check both sides of the dipstick, and read the


lower level. The fluid level must be between the upper mark and the lower mark.


4. If the fluid level is in the acceptable range,


push the dipstick back in all the way.


329


Manual Transaxle Fluid It is not necessary to check the transaxle fluid level. A transaxle fluid leak is the only reason for fluid loss. If a leak occurs, take the vehicle to your retailer’s service department and have it repaired as soon as possible. See Recommended Fluids and Lubricants on page 432 for the proper fluid to use. Notice: Use of manual transaxle fluid other than that listed in the Maintenance Schedule may damage your vehicle, and the damages may not be covered by your warranty. Always use the correct manual transaxle fluid in your vehicle. See Recommended Fluids and Lubricants on page 432 for the correct manual transaxle fluid.


How to Add Automatic Transaxle Fluid Refer to the Maintenance Schedule to determine what kind of transaxle fluid to use. See Recommended Fluids and Lubricants on page 432. 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 432. 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.


330


Hydraulic Clutch The hydraulic clutch linkage in your vehicle is self-adjusting. The hydraulic clutch system does not have its own reservoir. The system receives fluid from the brake master cylinder reservoir. It is filled with DOT-3 brake fluid. See Brakes on page 343 for more information.


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 334.


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® 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.


331


(cid:129) 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 you have to add coolant more than four times a year, have your retailer check your 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 432 for more information.


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 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.


332


Checking Coolant


The surge tank is located on the driver’s side of the engine compartment. See Engine Compartment Overview on page 314 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 COLD FILL line. When your engine is warm, the level should be at the COLD FILL line or a little higher.


333


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. See Engine Overheating on page 334 for instructions on “How to Add Coolant to the Coolant Surge Tank.”


{CAUTION:


You can be burned if you spill coolant on hot engine parts. Coolant contains ethylene glycol, and it will burn if the engine parts are hot enough. Do not spill coolant on a hot engine.


When replacing the pressure cap, make sure it is hand-tight and fully seated.


If the pressure cap is not tightly


Coolant Surge Tank Pressure Cap Notice: installed, coolant loss and possible engine damage may occur. Be sure the cap is properly and tightly secured. If you need to replace your coolant surge tank pressure cap, see your retailer.


Engine Overheating You will find a coolant temperature gage and a coolant temperature warning light on your vehicle’s instrument panel. See Engine Coolant Temperature Gage on page 174 and Engine Coolant Temperature Warning Light on page 173.


334


If Steam Is Coming From Your Engine


{CAUTION:


Steam from an overheated engine can burn you badly, even if you just open the hood. Stay away from the engine if you see or hear steam coming from it. Just turn it off and get everyone away from the vehicle until it cools down. Wait until there is no sign of steam or coolant before you open the hood. If you keep driving when your engine is overheated, the liquids in it can catch fire. You or others could be badly burned. Stop your engine if it overheats, and get out of the vehicle until the engine is cool.


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.


If No Steam Is Coming From Your Engine If you get an engine overheat warning, but see or hear no steam, the problem may not be too serious. Sometimes the engine can get a little too hot when you: (cid:129) Climb a long hill on a hot day. (cid:129) Stop after high-speed driving. Idle for long periods in traffic.


(cid:129) Tow a trailer. If you get the overheat warning with no sign of steam, try this for a minute or so: 1. If you have an air conditioner and it is on,


turn it off.


2. Turn on your heater to full hot at the highest


fan speed and open the windows as necessary.


3. Try to minimize engine load. If you are in a traffic jam, shift to NEUTRAL (N); otherwise, shift to the highest gear possible while driving.


335


(cid:129) Cooling System When you decide it is safe to lift the hood, here is what you will see:


If you no longer have the overheat warning, you can drive. Just to be safe, drive slower for about ten minutes. If the warning does not come back on, you can drive normally. If the warning continues and you have not stopped, pull over, stop, and park your vehicle right away. If there is still no sign of steam, you can idle the engine for three minutes while you are parked. If you still have the warning, turn off the engine and get everyone out of the vehicle until it cools down. You may decide not to lift the hood but to get service help right away.

{CAUTION:


CAUTION:


(Continued)


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.


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 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. The coolant level should be at the COLD FILL line. If it is not, you may have a leak at 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. (Continued)


CAUTION:


If there seems to be no leak, with the engine on, check to see if the electric engine cooling fan is running. If the engine is overheating, the fan should be running. If it is not, your vehicle needs service. Turn off the engine. Notice: Engine damage from running your engine without coolant is not covered by your warranty. 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.


337


How to Add Coolant to the Coolant Surge Tank Notice: This vehicle has a specific coolant fill procedure. Failure to follow this procedure could cause your engine to overheat and be severely damaged. If you have not found a problem yet, check to see if coolant is visible in the surge tank. If coolant is visible but the coolant level is not at the COLD FILL line, 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 331 for more information.


{CAUTION:


Steam and scalding liquids from a hot cooling system can blow out and burn you badly. They are under pressure, and if you turn the coolant surge tank pressure cap — even a little — they can come out at high speed. Never turn the cap when the 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.


338


{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.


In cold weather, water can freeze and


Notice: crack the engine, radiator, heater core and other parts. Use the recommended coolant and the proper coolant mixture.


{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.


339


3. Fill the coolant surge tank with the proper DEX-COOL® coolant mixture, to the COLD FILL line.


1. You can remove the coolant surge tank pressure cap when the cooling system, including the coolant surge tank pressure cap and upper radiator hose, is no longer hot. Turn the pressure cap slowly counterclockwise about one-quarter of a turn. 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.


340


Check the level in the surge tank when the cooling system has cooled down. If the coolant is not at the proper level, repeat Steps 1 through 3 and reinstall the pressure cap. If the coolant still is not at the proper level when the system cools down again, see your retailer.


Windshield Washer Fluid What to Use When you need windshield or rear window 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.


341


4. With the coolant surge tank pressure cap off,


start the engine and let it run until you can feel the upper radiator hose getting hot. Watch out for the engine cooling fan. By this time, the coolant level inside the coolant surge tank may be lower. If the level is lower, add more of the proper DEX-COOL® coolant mixture to the coolant surge tank until the level reaches the COLD FILL line. 5. Then replace the pressure cap. Be sure the


pressure cap is hand-tight.


Adding Windshield Washer Fluid


Open the cap with the washer symbol on it. Add washer fluid until the tank is full. See Engine Compartment Overview on page 314
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.


(cid:129) 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.


342


Brakes Brake Fluid


The brake master cylinder reservoir is filled with DOT-3 brake fluid. See Engine Compartment Overview on page 314 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 the brake system fixed, since a leak means that sooner or later the brakes will not work well.


So, it is not a good idea to top off the brake fluid. Adding brake fluid will not correct a leak. If you add fluid when the 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 the brake fluid falls to a low level, the brake warning light will come on. See Brake System Warning Light on page 170.


343


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 432. 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. This could cause a crash. Always use the proper brake fluid.


Notice: (cid:129) 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 402.


344


(cid:129) Brake Wear Your vehicle has front disc brakes and rear drum 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.


{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 414. The rear drum brakes do not have wear indicators, but if you ever hear a rear brake rubbing noise, have the rear brake linings inspected immediately. Also, the rear brake drums should be removed and inspected each time the tires are removed for rotation or changing. When you have the front brake pads replaced, have the rear brakes inspected, too. Brake linings should always be replaced as complete axle sets.


345


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 make a moderate brake stop, the brakes adjust for wear. If you rarely make a moderate or heavier stop, then the brakes might not adjust correctly. If you drive in that way, then — very carefully — make a few moderate brake stops about every 1,000 miles (1 600 km), so the brakes will adjust properly.


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.


346


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 314 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 the 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 348 for tips on working around a battery without getting hurt.


347


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:129) They contain acid that can burn you. (cid:129) They contain gas that can explode or


(cid:129) They contain enough electricity to


ignite.


burn you.


If you do not follow these steps exactly, some or all of these things can hurt you.


Ignoring these steps could result in


Notice: costly damage to your vehicle that would not be covered by your warranty.


348


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


Notice: 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.


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 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!


4. Open the hood on the other vehicle and locate the positive (+) and negative (−) terminal locations on that vehicle. Open the hood on your vehicle and find the remote positive (+) and remote negative (−) jump starting terminals.


A. Remote Positive B. Remote Negative


2.2L L4 Engine


Vehicles equipped with the 2.2L L4 engine, the remote positive (+) terminal is located in the engine compartment on the driver’s side of the vehicle, on the underhood fuse block. See Engine Compartment Overview on page 314 for more information on location. Access the remote positive (+) terminal by removing the fuse block cover. The remote negative (−) terminal is the lift hook, which is located towards the rear of the engine on the driver’s side.


349


A. Remote Negative B. Positive Terminal


3.5L V6 Engine


Vehicle equipped with the 3.5L V6 engine, the positive (+) terminal is located in the engine compartment on the driver’s side of the vehicle on the battery. The negative (−) terminal is located in the engine compartment on the driver’s side of the vehicle. See Engine Compartment Overview on page 314 for more information on location.


After unsnapping and opening the black cap on the positive (+) terminal on the top of the battery, clamp the jumper cable to the terminal. Place the negative (-) jumper cable clamp on the nut on the end of the engine.


{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.


350


{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.


351


6. Connect the red positive (+) cable to the positive (+) terminal on 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 of the good battery. Use a remote positive (+) terminal if the vehicle has one.


8. Now connect the black negative (−) cable to the negative (−) terminal of the good battery. Use a remote negative (−) terminal if the vehicle has one. Do not let the other end touch anything until the next step. The other end of the negative (−) cable does not go to the dead battery. It goes to a heavy, unpainted metal engine part or to a remote negative (−) terminal on the vehicle with the dead battery.


9. Connect the other end of the negative (−) cable 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. Your vehicle has a remote negative (−) terminal for this purpose.


10. Now start the vehicle with the good battery


and run the engine for a while.


11. Press the unlock symbol on the remote keyless entry transmitter to disarm your security system, if equipped.


12. Try to start the vehicle that had the dead


battery. If it will not start after a few tries, it probably needs service.

All-Wheel Drive If you have an all-wheel-drive vehicle, be sure to perform the lubricant checks described in this section. There are two additional systems that need lubrication.


353


Transfer Case (3.5L V6 Engine) When to Check and Change Lubricant Refer to the Maintenance Schedule to determine how often to check the lubricant and when to change it. See Scheduled Maintenance on page 420. How to Check Lubricant


To get an accurate reading, the vehicle should be on a level surface. If the level is below the bottom of the filler plug hole, located on the transfer case, you’ll need to add some lubricant. Add enough lubricant to raise the level to the bottom of the filler plug hole. A fluid loss could indicate a problem; check and have it repaired, if needed. What to Use Refer to the Maintenance Schedule to determine what kind of lubricant to use. See Recommended Fluids and Lubricants on page 432.


A. Fill Plug B. Drain Plug


354


Headlamp Aiming The visual optical headlamp aiming system has been preset at the factory and should need no further adjustment. However, if the vehicle is damaged in an accident, the aim of the headlamps may be affected and adjustment may be necessary. If oncoming vehicles flash their high beams at you, this may mean the vertical aim of your headlamps needs to be adjusted. It is recommended that the vehicle is taken to your dealer/retailer for service if the headlamps need to be adjusted. It is possible however, to re-aim the headlamps as described. The vehicle should be properly prepared as follows: (cid:129) The vehicle should be placed so the


headlamps are 25 ft. (7.6 m) from a light colored wall.


(cid:129) The vehicle must have all four tires on a level surface which is level all the way to the wall.


(cid:129) The vehicle should be placed so it is


perpendicular to the wall or other flat surface. (cid:129) The vehicle should not have any snow, ice, or


mud on it.


(cid:129) The vehicle should be fully assembled and all other work stopped while headlamp aiming is being performed.


(cid:129) The vehicle should be normally loaded with a


full tank of fuel and one person or 160 lbs (75 kg) sitting on the driver’s seat. (cid:129) Tires should be properly inflated. (cid:129) The spare tire is in its proper location in


the vehicle.


Headlamp aiming is done with the vehicle’s low-beam headlamps. The high-beam headlamps will be correctly aimed if the low-beam headlamps are aimed properly.


355


To adjust the vertical aim: 1. Open the hood. See Hood Release on


page 313 for more information.


4. At the wall measure from the ground upward (A) to the recorded distance from Step 3 and mark it.


5. Draw or tape a horizontal line (B) on the wall


the width of the vehicle at the height of the mark in Step 4.


Notice: Do not cover a headlamp to improve beam cut-off when aiming. Covering a headlamp may cause excessive heat build-up which may cause damage to the headlamp. 6. Turn on the low-beam headlamps and place a piece of cardboard or equivalent in front of the headlamp not being adjusted. This allows only the beam of light from the headlamp being adjusted to be seen on the flat surface.


2. Locate the aim dot on the lens of the


low-beam headlamp.


3. Measure the distance from the ground to the aim dot on the low-beam headlamp. Record the distance.


356


9. Make sure that the light from the headlamp is positioned at the bottom edge of the horizontal tape line. The lamp on the left (A) shows the correct headlamp aim. The lamp on the right (B) shows the incorrect headlamp aim.


10. Repeat Steps 7 through 9 for the opposite


headlamp.


7. Locate the vertical headlamp aiming screws,


which are under the hood near each headlamp assembly. The adjustment screw can be turned with a 6 mm socket.


8. Turn the vertical aiming screw until the headlamp beam is aimed to the horizontal tape line. Turn it clockwise or counterclockwise to raise or lower the angle of the beam.

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 Saturn Warranty booklet for details. For additional information refer to the tire manufacturer’s booklet included with your vehicle.


{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 friction. You could have an air-out and a serious accident. See Loading Your Vehicle on page 279. (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.


CAUTION:


(Continued)


366


CAUTION:


(Continued)


Tire pressure should be checked when your vehicle’s tires are cold. See Inflation - Tire Pressure on page 374.


(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.


Low-Profile Performance Tire (Red Line) If your vehicle has P245/50R18 size tires, they are classified as low-profile performance tires. These tires are designed for very responsive driving on wet or dry pavement. You may also notice more road noise with low-profile performance tires and that they tend to wear faster.


If your vehicle has low-profile tires,


Notice: they are more susceptible to damage from road hazards or curb impact than standard profile tires. Tire and/or wheel assembly damage can occur when coming into contact with road hazards like, potholes, or sharp edged objects, or when sliding into a curb. Your Saturn Warranty does not cover this type of damage. Keep tires set to the correct inflation pressure and, when possible avoid contact with curbs, potholes, and other road hazards.

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 Tire and Loading Information label is attached to the vehicle’s center pillar (B-pillar). This label shows your vehicle’s original equipment tires and the correct inflation pressures for your tires when they are cold. The recommended cold tire inflation pressure, shown on the label, is the minimum amount of air pressure needed to support your vehicle’s maximum load carrying capacity. For additional information regarding how much weight your vehicle can carry, and an example of the Tire and Loading Information label, see Loading Your Vehicle on page 279. 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 398.


374


How to Check Use a good quality pocket-type gage to check tire pressure. You cannot tell if your tires are properly inflated simply by looking at them. Radial tires may look properly inflated even when they are under-inflated. Check the tire’s inflation pressure when the tires are cold. Cold means your vehicle has been sitting for at least three hours or driven no more than 1 mile (1.6 km). Remove the valve cap from the tire valve stem. Press the tire gage firmly onto the valve to get a pressure measurement. If the cold tire inflation pressure matches the recommended pressure on the Tire and Loading Information label, no further adjustment is necessary. If the inflation pressure is low, add air until you reach the recommended amount. If you overfill the tire, release air by pushing on the metal stem in the center of the tire valve. Re-check the tire pressure with the tire gage.


Be sure to put the valve caps back on the valve stems. They help prevent leaks by keeping out dirt and moisture.


Tire Inspection and Rotation Tires should be rotated every 5,000 to 8,000 miles (8 000 to 13 000 km). Any time you notice unusual wear, rotate your tires as soon as possible and check wheel alignment. Also check for damaged tires or wheels. See When It Is Time for New Tires on page 377
and Wheel Replacement on page 382 for more information. The purpose of regular rotation is to achieve more uniform wear for all tires on the vehicle. The first rotation is the most important. See Scheduled Maintenance on page 420.


375


When towing your vehicle with all four wheels on the ground, the vehicle’s odometer will not record the miles generated while towing. Keep a record of how many miles your vehicle was towed so they can be added to the mileage on the vehicle’s odometer when following your maintenance schedule for recommended services.


After the tires have been rotated, adjust the front and rear inflation pressures as shown on the Tire and Loading Information label. See Loading Your Vehicle on page 279. Make certain that all wheel nuts are properly tightened. See “Wheel Nut Torque” under Capacities and Specifications on page 414.


{CAUTION:


Rust or dirt on a wheel, or on the parts to which it is fastened, can make wheel nuts become loose after time. The wheel could come off and cause an accident. When you change a wheel, remove any rust or dirt from places where the wheel attaches to the vehicle. In an emergency, you can use a cloth or a paper towel to do this; but be sure to use a scraper or wire brush later, if needed, to get all the rust or dirt off. See Changing a Flat Tire on page 386.


When rotating your tires, always use the correct rotation pattern shown here. Do not include the compact spare tire in your tire rotation.


376


When It Is Time for New Tires


One way to tell when it is time for new tires is to check the treadwear indicators, which will appear when your tires have only 1/16 inch (1.6 mm) or less of tread remaining.


You need a new tire if any of the following statements are true: (cid:129) You can see the indicators at three or more


places around the tire.


(cid:129) You can see cord or fabric showing through


the tire’s rubber.


(cid:129) The tread or sidewall is cracked, cut, or


snagged deep enough to show cord or fabric.


(cid:129) The tire has a bump, bulge, or split. (cid:129) The tire has a puncture, cut, or other damage


that cannot be repaired well because of the size or location of the damage.


Buying New Tires GM has developed and matched specific tires for your vehicle. The original equipment tires installed on your vehicle, when it was new, were designed to meet General Motors Tire Performance Criteria Specification (TPC spec) system rating. If you need replacement tires, GM strongly recommends that you get tires with the same TPC Spec rating. This way, your vehicle will continue to have tires that are designed to give the same performance and vehicle safety, during normal use, as the original tires.


377


GM’s exclusive TPC Spec system considers over a dozen critical specifications that impact the overall performance of your vehicle, including brake system performance, ride and handling, traction control, and tire pressure monitoring performance. GM’s TPC Spec number is molded onto the tire’s sidewall by the tire manufacturer. If the tires have an all-season tread design, the TPC spec number will be followed by an MS for mud and snow. See Tire Sidewall Labeling on page 367 for additional information.


{CAUTION:


Mixing tires could cause you to lose control while driving. If you mix tires of different sizes, brands, or types (radial and bias-belted tires), the vehicle may not handle properly, and you could have a crash. Using tires of different sizes,


CAUTION:


(Continued)


CAUTION:


(Continued)


brands, or types may also cause damage to your vehicle. Be sure to use the correct size, brand, and type of tires on all wheels. It is all right to drive with your compact spare temporarily, as it was developed for use on your vehicle. See Compact Spare Tire on page 398.


{CAUTION:


If you use bias-ply tires on your vehicle, the wheel rim flanges could develop cracks after many miles of driving. A tire and/or wheel could fail suddenly, causing a crash. Use only radial-ply tires with the wheels on your vehicle.


378


If you must replace your vehicle’s tires with those that do not have a TPC Spec number, make sure they are the same size, load range, speed rating, and construction type (radial and bias-belted tires) as your vehicle’s original tires. Your vehicle’s original equipment tires are listed on the Tire and Loading Information label. This label is attached to the vehicle’s center pillar (B-pillar). See Loading Your Vehicle on page 279, for more information about the Tire and Loading Information label and its location on your vehicle.


Different Size Tires and Wheels If you add wheels or tires that are a different size than your original equipment wheels and tires, this may affect the way your vehicle performs, including its braking, ride and handling characteristics, stability, and resistance to rollover. Additionally, if your vehicle has electronic systems such as, anti-lock brakes, traction control, and stability control, the performance of these systems can be affected.


{CAUTION:


If you add different sized wheels, your vehicle may not provide an acceptable level of performance and safety if tires not recommended for those wheels are selected. You may increase the chance that you will crash and suffer serious injury. Only use Saturn specific wheel and tire systems developed for your vehicle, and have them properly installed by a Saturn certified technician.


See Buying New Tires on page 377 and Accessories and Modifications on page 304 for additional information.


379


Uniform Tire Quality Grading Quality grades can be found where applicable on the tire sidewall between tread shoulder and maximum section width. For example: Treadwear 200 Traction AA Temperature A The following information relates to the system developed by the United States National Highway Traffic Safety Administration (NHTSA), which grades tires by treadwear, traction, and temperature performance. This applies only to vehicles sold in the United States. The grades are molded on the sidewalls of most passenger car tires. The Uniform Tire Quality Grading (UTQG) system does not apply to deep tread, winter-type snow tires, space-saver, or temporary use spare tires, tires with nominal rim diameters of 10 to 12 inches (25 to 30 cm), or to some limited-production tires.


While the tires available on General Motors passenger cars and light trucks may vary with respect to these grades, they must also conform to federal safety requirements and additional General Motors Tire Performance Criteria (TPC) standards. Treadwear The treadwear grade is a comparative rating based on the wear rate of the tire when tested under controlled conditions on a specified government test course. For example, a tire graded 150 would wear one and a half (1.5) times as well on the government course as a tire graded 100. The relative performance of tires depends upon the actual conditions of their use, however, and may depart significantly from the norm due to variations in driving habits, service practices, and differences in road characteristics and climate.


380


Traction – AA, A, B, C The traction grades, from highest to lowest, are AA, A, B, and C. Those grades represent the tire’s ability to stop on wet pavement as measured under controlled conditions on specified government test surfaces of asphalt and concrete. A tire marked C may have poor traction performance. Warning: The traction grade assigned to this tire is based on straight-ahead braking traction tests, and does not include acceleration, cornering, hydroplaning, or peak traction characteristics.


Temperature – A, B, C The temperature grades are A (the highest), B, and C, representing the tire’s resistance to the generation of heat and its ability to dissipate heat when tested under controlled conditions on a specified indoor laboratory test wheel. Sustained high temperature can cause the material of the tire to degenerate and reduce tire life, and excessive temperature can lead to sudden tire failure. The grade C corresponds to a level of performance which all passenger car tires must meet under the Federal Motor Vehicle Safety Standard No. 109. Grades B and A represent higher levels of performance on the laboratory test wheel than the minimum required by law. Warning: The temperature grade for this tire is established for a tire that is properly inflated and not overloaded. Excessive speed, underinflation, or excessive loading, either separately or in combination, can cause heat buildup and possible tire failure.

Wheel Alignment and Tire Balance The tires and wheels on your vehicle were aligned and balanced carefully at the factory to give you the longest tire life and best overall performance. Adjustments to wheel alignment and tire balancing will not be necessary on a regular basis. However, if you notice unusual tire wear or your vehicle pulling to one side or the other, the alignment may need to be checked. If you notice your vehicle vibrating when driving on a smooth road, your tires and wheels may need to be rebalanced. See your retailer for proper diagnosis.


Wheel Replacement Replace any wheel that is bent, cracked or badly rusted or corroded. If wheel nuts keep coming loose, the wheel, wheel bolts and wheel nuts should be replaced. If the wheel leaks air, replace it (except some aluminum wheels, which can sometimes be repaired). See your dealer/retailer if any of these conditions exist. Your dealer/retailer will know the kind of wheel you need. Each new wheel should have the same load-carrying capacity, diameter, width, offset and be mounted the same way as the one it replaces.


382


If you need to replace any of your wheels, wheel bolts or wheel nuts, replace them only with new Saturn original equipment parts. This way, you will be sure to have the right wheel, wheel bolts and wheel nuts for your vehicle.


{CAUTION:


Using the wrong replacement wheels, wheel bolts, or wheel nuts on your vehicle can be dangerous. It could affect the braking and handling of your vehicle, make your tires lose air and make you lose control. You could have a collision in which you or others could be injured. Always use the correct wheel, wheel bolts, and wheel nuts for replacement.


Notice: The wrong wheel can also cause problems with bearing life, brake cooling, speedometer or odometer calibration, headlamp aim, bumper height, vehicle ground clearance, and tire or tire chain clearance to the body and chassis. See Changing a Flat Tire on page 386 for more information. Used Replacement Wheels


{CAUTION:


Putting a used wheel on your vehicle is dangerous. You cannot know how it has been used or how far it has been driven. It could fail suddenly and cause a crash. If you have to replace a wheel, use a new Saturn original equipment wheel.

Tire Chains


{CAUTION:


If your vehicle has P235/65R16, P235/ 60R17, or P245/50R18 size tires, do not use tire chains. They can damage your vehicle because there is not enough clearance. Tire chains used on a vehicle without the proper amount of clearance can cause damage to the brakes, suspension, or other vehicle parts. The area damaged by the tire chains could cause you to lose control of your vehicle and you or others may be injured in a crash. Use another type of traction device only if its manufacturer recommends it for use on your vehicle and tire size combination and road conditions. Follow that manufacturer’s instructions. To help avoid (Continued)

damage to your vehicle, drive slowly, readjust, or remove the device if it is contacting your vehicle, and do not spin your wheels. If you do find traction devices that will fit, install them on the front tires.


If your vehicle has a tire size other than


Notice: P235/65R16, P235/60R17, or P245/50R18 size tires, use tire chains only where legal and only when you must. Use only SAE Class “S” type chains that are the proper size for your tires. Install them on the front tires and tighten them as tightly as possible with the ends securely fastened. Drive slowly and follow the chain manufacturer’s instructions. If you can hear the chains contacting your vehicle, stop and retighten them. If the contact continues, slow down until it stops. Driving too fast or spinning the wheels with chains on will damage your vehicle.


If a Tire Goes Flat It is unusual for a tire to blowout while you are driving, especially if you maintain your vehicle’s tires properly. If air goes out of a tire, it is much more likely to leak out slowly. But if you should ever have a blowout, here are a few tips about what to expect and what to do: If a front tire fails, the flat tire will create a drag that pulls the vehicle toward that side. Take your foot off the accelerator pedal and grip the steering wheel firmly. Steer to maintain lane position, and then gently brake to a stop well out of the traffic lane. A rear blowout, particularly on a curve, acts much like a skid and may require the same correction you would use in a skid. In any rear blowout remove your foot from the accelerator pedal. Get the vehicle under control by steering the way you want the vehicle to go. It may be very bumpy and noisy, but you can still steer. Gently brake to a stop, well off the road if possible.


{CAUTION:


Lifting a vehicle and getting under it to do maintenance or repairs is dangerous without the appropriate safety equipment and training. The jack provided with your vehicle is designed only for changing a flat tire. If it is used for anything else, you or others could be badly injured or killed if the vehicle slips off the jack. Use the jack provided with your vehicle only for changing a flat tire.


If a tire goes flat, the next part shows how to use the jacking equipment to change a flat tire safely.

Changing a Flat Tire If a tire goes flat, avoid further tire and wheel damage by driving slowly to a level place. Turn on your hazard warning flashers.


{CAUTION:


Changing a tire can be dangerous. The vehicle can slip off the jack and roll over or fall on you or other people. You and they could be badly injured or even killed. Find a level place to change your tire. To help prevent the vehicle from moving:


1. Set the parking brake firmly. 2. Put an automatic transaxle shift lever


in PARK (P), or shift a manual transaxle to FIRST (1) or REVERSE (R). (Continued)


CAUTION:


CAUTION:


(Continued)


3. Turn off the engine and do not restart


while the vehicle is raised.


4. Do not allow passengers to remain in


the vehicle.


To be even more certain the vehicle will not move, you should put blocks at the front and rear of the tire farthest away from the one being changed. That would be the tire on the other side, at the opposite end of the vehicle.


When you have a flat tire, use the following example as a guide to assist you in the placement of wheel blocks.
