When you’re turning with a trailer, make wider turns than normal. Do this so your trailer won’t strike soft shoulders, curbs, road signs, trees or other objects. Avoid jerky or sudden maneuvers. Signal well in advance. Turn Signals When Towing a Trailer The arrows on your instrument panel will ﬂash whenever you signal a turn or lane change. Properly hooked up, the trailer lamps will also ﬂash, telling other drivers you’re about to turn, change lanes or stop. When towing a trailer, the arrows on your instrument panel will ﬂash for turns even if the bulbs on the trailer are burned out. Thus, you may think drivers behind you are seeing your signal when they are not. It’s important to check occasionally to be sure the trailer bulbs are still working. Driving On Grades Reduce speed and shift to a lower gear before you start down a long or steep downgrade. If you don’t shift down, you might have to use your brakes so much that they would get hot and no longer work well. You can tow in DRIVE (D). You may want to shift the transmission to THIRD (3) or a lower gear, under heavy loads or hilly conditions. When towing at high altitude on steep uphill grades, consider the following: Engine coolant will boil at a lower temperature than at normal altitudes. If you turn your engine off immediately after towing at high altitude on steep uphill grades, your vehicle may show signs similar to engine overheating. To avoid this, let the engine run while parked (preferably on level ground) with the automatic transmission in PARK (P) for a few minutes before turning the engine off. If you do get the overheat warning, see Engine Overheating on page 5-27. 4-49 Parking on Hills {CAUTION: You really should not park your vehicle, with a trailer attached, on a hill. If something goes wrong, your rig could start to move. People can be injured, and both your vehicle and the trailer can be damaged. But if you ever have to park your rig on a hill, here’s how to do it: 1. Apply your regular brakes, but don’t shift into PARK (P) yet. When parking uphill, turn your wheels away from the curb. When parking downhill, turn your wheels into the curb. 2. Have someone place chocks under the trailer wheels. 3. When the wheel chocks are in place, release the regular brakes until the chocks absorb the load. 4. Reapply the regular brakes. Then apply your parking brake, and then shift into PARK (P). 5. Release the regular brakes. 4-50 When You Are Ready to Leave After Parking on a Hill 1. Apply your regular brakes and hold the pedal down while you: start your engine, shift into a gear, and release the parking brake. 2. Let up on the brake pedal. 3. Drive slowly until the trailer is clear of the chocks. 4. Stop and have someone pick up and store the chocks. Maintenance When Trailer Towing Your vehicle will need service more often when you’re pulling a trailer. See the Maintenance Schedule for more on this. Things that are especially important in trailer operation are automatic transmission ﬂuid (don’t overﬁll), engine oil, axle lubricant, belt(s), cooling system and brake system. Each of these is covered in this manual, and the Index will help you ﬁnd them quickly. If you’re trailering, it’s a good idea to review these sections before you start your trip. Check periodically to see that all hitch nuts and bolts are tight. (cid:127) (cid:127) (cid:127) Trailer Wiring Harness Your vehicle is equipped with a seven-wire trailer towing harness. This harness has a seven-pin universal heavy-duty trailer connector (if equipped with the trailering package) that is attached to a bracket on the hitch platform. If your vehicle is not equipped with the heavy-duty trailer connector, you can purchase one from your Saab dealer. The seven-wire harness contains the following trailer circuits: (cid:127) Yellow: Left Stop/Turn Signal (cid:127) Dark Green: Right Stop/Turn Signal (cid:127) Brown: Running Lamps (cid:127) White: Ground Light Green: Back-up Lamps (cid:127) Dark Blue: Electric Brakes (cid:127) Red: Battery Feed (The chassis wiring ring terminal must be fastened to a stud on the underhood electrical center before the trailer feed will become active.) If you need to tow a light-duty trailer with a standard four-way round pin connector, an adapter connector is available from your dealer. Your vehicle is also equipped with wiring for an electric trailer brake controller. These wires are located inside the vehicle on the driver’s side under the instrument panel. These wires should be connected to an electric trailer brake controller by your dealer or a qualiﬁed service center. 4-51 (cid:127) ✍ NOTES 4-52 Section 5 Service and Appearance Care Service ............................................................5-3 Accessories and Modiﬁcations ..........................5-3 California Proposition 65 Warning .....................5-3 Doing Your Own Service Work .........................5-4 Adding Equipment to the Outside of Your Vehicle ...5-4 Fuel ................................................................5-5 Gasoline Octane ............................................5-5 Gasoline Speciﬁcations ....................................5-5 California Fuel ...............................................5-5 Additives .......................................................5-6 Fuels in Foreign Countries ...............................5-7 Filling the Tank ..............................................5-8 Filling a Portable Fuel Container .....................5-10 Checking Things Under the Hood ....................5-10 Hood Release ..............................................5-11 Engine Compartment Overview .......................5-12 Engine Oil ...................................................5-16 Engine Oil Life System ..................................5-19 Engine Air Cleaner/Filter ................................5-21 Automatic Transmission Fluid .........................5-22 Engine Coolant .............................................5-24 Radiator Pressure Cap ..................................5-27 Engine Overheating .......................................5-27 Cooling System ............................................5-29 Engine Fan Noise .........................................5-34 Power Steering Fluid .....................................5-35 Windshield Washer Fluid ................................5-36 Brakes ........................................................5-37 Battery ........................................................5-40 Jump Starting ...............................................5-41 All-Wheel Drive ..............................................5-46 Rear Axle .......................................................5-47 Front Axle ......................................................5-48 Headlamp Aiming ...........................................5-49 Bulb Replacement ..........................................5-49 High Intensity Discharge (HID) Lighting ............5-49 Halogen Bulbs ..............................................5-50 Headlamps, Front Turn Signal, Sidemarker, and Parking Lamps ....................................5-50 Taillamps, Turn Signal, Sidemarker, Stoplamps and Back-up Lamps ...................5-52 Replacement Bulbs .......................................5-53 Windshield Replacement .................................5-53 Windshield Wiper Blade Replacement ..............5-53 Tires ..............................................................5-56 Tire Sidewall Labeling ...................................5-57 Tire Terminology and Deﬁnitions .....................5-60 Inﬂation -

We hope you will go to your dealer for all your service and parts needs. Accessories and Modiﬁcations When you add non-Saab accessories to your vehicle they can affect your vehicle’s performance and safety, including such things as, braking, stability, ride and handling, emissions systems, aerodynamics, durability, and electronic systems like antilock brakes, traction control, and stability control. Some of these accessories may even cause malfunction or damage not covered by warranty. Saab Accessories are designed to complement and function with other systems on your vehicle. Your Saab dealer can accessorize your vehicle using genuine Saab Accessories. When you go to your Saab dealer and ask for Saab Accessories, you will know that Saab-trained and supported service technicians will perform the work using genuine Saab Accessories. 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. 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:127) Be sure you have sufficient knowledge, experience, the proper replacement parts, and tools before you attempt any vehicle maintenance task. (cid:127) Be sure to use the proper nuts, bolts, and other fasteners. English and metric fasteners can be easily confused. If you use the wrong fasteners, parts can later break or fall off. You could be hurt. If you want to do some of your own service work, you will want to use the proper service manual. It tells you much more about how to service your vehicle than this manual can. Your vehicle has an airbag system. Before attempting to do your own service work, see Servicing Your Airbag-Equipped Vehicle on page 1-65. 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 6-15. Adding Equipment to the Outside of Your Vehicle Things you might add to the outside of your vehicle can affect the airﬂow around it. This may cause wind noise and affect windshield washer performance. Check with your dealer before adding equipment to the outside of your vehicle. 5-4 Fuel Use of the recommended fuel is an important part of the proper maintenance of your vehicle. Gasoline Octane Use regular unleaded gasoline with a posted octane rating of 87 or higher. If the octane rating is less than 87, you may notice an audible knocking noise when you drive, commonly referred to as spark knock. If this occurs, use a gasoline rated at 87 octane or higher as soon as possible. If you are using gasoline rated at 87 octane or higher and you hear heavy knocking, your engine needs service. Gasoline Speciﬁcations At a minimum, gasoline should meet ASTM speciﬁcation D 4814 in the United States or CAN/CGSB-3.5 in Canada. Some gasolines may contain an octane-enhancing additive called methylcyclopentadienyl manganese tricarbonyl (MMT). We recommend against the use of gasolines containing MMT. See Additives on page 5-6 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 may be affected. The malfunction indicator lamp may turn on and your vehicle may fail a smog-check test. See Malfunction Indicator Lamp on page 3-36. If this occurs, return to your authorized dealer for diagnosis. If it is determined that the condition is caused by the type of fuel used, repairs may not be covered by your warranty. 5-5 Additives To provide cleaner air, all gasolines in the United States are now required to contain additives that will help prevent engine and fuel system deposits from forming, allowing your emission control system to work properly. In most cases, you should not have to add anything to your fuel. However, some gasolines contain only the minimum amount of additive required to meet U.S. Environmental Protection Agency regulations. To help keep fuel injectors and intake valves clean, or if your vehicle experiences problems due to dirty injectors or valves, look for gasoline that is advertised as TOP TIER Detergent Gasoline. Also, your dealer has additives that will help correct and prevent most deposit-related problems. Gasolines containing oxygenates, such as ethers and ethanol, and reformulated gasolines may be available in your area. 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 your fuel system and also damage the plastic and rubber parts. That damage would not be covered under your warranty. 5-6 Some gasolines that are not reformulated for low emissions may contain an octane-enhancing additive called methylcyclopentadienyl manganese tricarbonyl (MMT); ask the attendant where you buy gasoline whether the fuel contains MMT. 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 may be affected. The malfunction indicator lamp may turn on. If this occurs, return to your authorized dealer for service. Fuels in Foreign Countries If you plan on driving in another country outside the United States or Canada, the proper fuel may be hard to ﬁnd. Never use leaded gasoline or any other fuel not recommended in the previous text on fuel. Costly repairs caused by use of improper fuel would not be covered by your warranty. To check the fuel availability, ask an auto club, or contact a major oil company that does business in the country where you will be driving. 5-7 Filling the Tank {CAUTION: Fuel vapor burns violently and a fuel ﬁre can cause bad injuries. To help avoid injuries to you and others, read and follow all the instructions on the pump island. Turn off your engine when you are refueling. Do not smoke if you are near fuel or refueling your vehicle. Keep sparks, ﬂames, and smoking materials away from fuel. Do not leave the fuel pump unattended when refueling your vehicle — this is against the law in some places. Keep children away from the fuel pump; never let children pump fuel. 5-8 The tethered fuel cap is located behind a hinged fuel door on the driver’s side of the vehicle. To remove the fuel cap, turn it slowly counterclockwise. While refueling, hang the tethered fuel cap from the hook on the fuel door. {CAUTION: If you spill fuel and then something ignites it, you could be badly burned. Fuel can spray out on you if you open the fuel cap too quickly. This spray can happen if your tank is nearly full, and is more likely in hot weather. Open the fuel cap slowly and wait for any hiss noise to stop. Then unscrew the cap all the way. Be careful not to spill fuel. Do not top off or overﬁll the tank and wait a few seconds after you have ﬁnished pumping before removing the nozzle. Clean fuel from painted surfaces as soon as possible. See Washing Your Vehicle on page 5-92. When replacing the fuel cap, turn it clockwise until it clicks. Make sure the cap is fully installed. The diagnostic system can determine if the fuel cap has been left off or improperly installed. This would allow fuel to evaporate into the atmosphere. See Malfunction Indicator Lamp on page 3-36. There may also be a light that comes on in the instrument panel to let you know if your gas cap is not properly installed. See Check Gas Cap Light on page 3-43 for more information. {CAUTION: If a ﬁre starts while you are refueling, do not remove the nozzle. Shut off the ﬂow of fuel by shutting off the pump or by notifying the station attendant. Leave the area immediately. Notice: If you need a new fuel cap, be sure to get the right type. Your dealer can get one for you. If you get the wrong type, it may not ﬁt properly. This may cause your malfunction indicator lamp to light and may damage your fuel tank and emissions system. See Malfunction Indicator Lamp on page 3-36. 5-9 Checking Things Under the Hood {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. Filling a Portable Fuel Container {CAUTION: Never ﬁll a portable fuel container while it is in your vehicle. Static electricity discharge from the container can ignite the gasoline vapor. You can be badly burned and your vehicle damaged if this occurs. To help avoid injury to you and others: (cid:127) Dispense gasoline only into approved containers. (cid:127) Do not ﬁll a container while it is inside a vehicle, in a vehicle’s trunk, pickup bed, or on any surface other than the ground. (cid:127) Bring the ﬁll nozzle in contact with the inside of the ﬁll opening before operating the nozzle. Contact should be maintained until the ﬁlling is complete. (cid:127) Do not smoke while pumping gasoline. 5-10 Hood Release 1. To open the hood, ﬁrst pull the handle with this symbol on it. It is located inside the vehicle under the instrument panel on the driver’s side. 2. Then go to the front of the vehicle and push the secondary hood latch up and to the right to release it, then lift the hood. Before closing the hood, be sure all the ﬁller caps are on properly. Then pull the hood down and close it ﬁrmly. Check to make sure the hood is closed and repeat the process if necessary. 5-11 Engine Compartment Overview When you open the hood on the 4.2L L6 engine, here is what you will see: 5-12 A.

Engine Compartment Fuse Block. See Engine Compartment Fuse Block on page 5-99. L. Battery. See Battery on page 5-40. 5-15 Engine Oil Checking Engine Oil It is a good idea to check your engine oil every time you get fuel. In order to get an accurate reading, the oil must be warm and the vehicle must be on level ground. The engine oil dipstick handle is a yellow loop. See Engine Compartment Overview on page 5-12 for the location of the engine oil dipstick. 1. Turn off the engine and give the oil several minutes to drain back into the oil pan. If you do not do this, the oil dipstick might not show the actual level. 2. Pull 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 L6 Engine V8 Engine 5-16 If the oil is below the cross-hatched area (L) for the L6 engine or below the cross-hatched area at the tip of the dipstick for the V8 engine, you will need to add at least one quart/liter of oil. But you must use the right kind. This section explains what kind of oil to use. For engine oil crankcase capacity, see Capacities and Speciﬁcations on page 5-108. Notice: Do not add too much oil. If your engine has so much oil that the oil level gets above the cross-hatched area (F) that shows the proper operating range for the L6 engine or above the cross-hatched area for the V8 engine, your engine could be damaged. See Engine Compartment Overview on page 5-12 for the location of the engine oil ﬁll cap. Be sure to add enough oil to put the level somewhere in the proper operating range. Push the dipstick all the way back in when you are through. 5-17 What Kind of Engine Oil to Use These numbers on an oil container show its viscosity, or thickness. Do not use other viscosity oils such as SAE 20W-50. Oils meeting these requirements should also have the starburst symbol on the container. This symbol indicates that the oil has been certiﬁed by the American Petroleum Institute (API). You should look for this information on the oil container, and use only those oils that are identiﬁed as meeting standard GM6094M and have the starburst symbol on the front of the oil container. Notice: Use only engine oil identiﬁed as meeting 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. Look for two things: (cid:127) GM6094M Your vehicle’s engine requires oil meeting standard GM6094M. You should look for and use only an oil that meets standard GM6094M. (cid:127) SAE 5W-30 As shown in the viscosity chart, SAE 5W-30 is best for your vehicle. 5-18 If you are in an area of extreme cold, where the temperature falls below −20°F (−29°C), it is recommended that you use either an SAE 5W-30 synthetic oil or an SAE 0W-30 oil. Both will provide easier cold starting and better protection for your engine at extremely low temperatures. Engine Oil Additives Do not add anything to your oil. The recommended oils with the starburst symbol that meet standard GM6094M are all you will need for good performance and engine protection. Engine Oil Life System When to Change Engine Oil Your vehicle has a computer system that lets you know when to change the engine oil and ﬁlter. This is based on engine revolutions and engine temperature, and not on mileage. Based on driving conditions, the mileage at which an oil change will be indicated can vary considerably. For the oil life system to work properly, you must reset the system every time the oil is changed. When the system has calculated that oil life has been diminished, it will indicate that an oil change is necessary. A CHANGE ENGINE OIL message will come on in the Driver Information Center (DIC). 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 may 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 has trained service people who will perform this work 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 your oil at 3,000 miles (5 000 km) since the last oil change. Remember to reset the oil life system whenever the oil is changed. 5-19 How to Reset the Engine Oil Life System The Engine Oil Life System calculates when to change your engine oil and ﬁlter based on vehicle use. Anytime your oil is changed, reset the system so it can calculate when the next oil change is required. If a situation occurs where you change your oil prior to a CHANGE ENGINE OIL message being turned on, reset the system. To reset the Engine Oil Life System, do the following: 1. Use the fuel button on the Driver Information Center to reach the ENGINE OIL LIFE screen. 2. Press and hold the select button on the Driver Information Center ﬁve seconds while ENGINE OIL LIFE is displayed. 3. OIL LIFE RESET will appear on the Driver Information Center (DIC) display for 10 seconds to let you know the system is reset. If the CHANGE ENGINE OIL message comes back on when you start your vehicle, the engine oil life system has not reset. Repeat the procedure. What to Do with Used Oil Used engine oil contains certain elements that may be unhealthy for your skin and could even cause cancer. Do not let used oil stay on your skin for very long. Clean your skin and nails with soap and water, or a good hand cleaner. Wash or properly dispose of clothing or rags containing used engine oil. See the manufacturer’s warnings about the use and disposal of oil products. Used oil can be a threat to the environment. If you change your own oil, be sure to drain all the oil from the ﬁlter before disposal. Never dispose of oil by putting it in the trash, pouring it on the ground, into sewers, or into streams or bodies of water. Instead, recycle it by taking it to a place that collects used oil. If you have a problem properly disposing of used oil, ask your dealer, a service station, or a local recycling center for help. 5-20 Engine Air Cleaner/Filter See Engine Compartment Overview on page 5-12 for the location of the engine air cleaner/ﬁlter. When to Inspect 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 6-4 for more information. If you are driving in dusty/dirty conditions, inspect the ﬁlter at each engine oil change. How to Inspect 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 ﬁlter, do the following: 1. Remove the screws on the engine cleaner/ﬁlter and lift off the cover. 2. Remove the air cleaner/ﬁlter from the housing. Care should be taken to dislodge as little dirt as possible. 3. Inspect or replace the engine air cleaner/ﬁlter. 4. Reinstall the cover and tighten the screws. {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 can Notice: cause a damaging engine ﬁre. And, dirt can easily get into your engine, which will damage it. Always have the air cleaner/ﬁlter in place when you are driving. 5-21 Automatic Transmission Fluid When to Check and Change Automatic Transmission Fluid A good time to check your automatic transmission ﬂuid level is when the engine oil is changed. 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. How to Check Automatic Transmission Fluid Because this operation can be a little difficult, you may choose to have this done at the dealership service department. If you do it yourself, be sure to follow all the instructions here, or you could get a false reading on the dipstick. Notice: Too much or too little ﬂuid can damage your transmission. Too much can mean that some of the ﬂuid could come out and fall on hot engine part or exhaust system parts, starting a ﬁre. Too little ﬂuid could cause the transmission to overheat. Be sure to get an accurate reading if you check your transmission ﬂuid. 5-22 Wait at least 30 minutes before checking the transmission ﬂuid level if you have been driving: (cid:127) When outside temperatures are above 90°F (32°C). (cid:127) At high speed for quite a while. In heavy traffic — especially in hot weather. (cid:127) 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), drive the vehicle in THIRD (3) until the engine temperature gage moves and then remains steady for 10 minutes. A cold ﬂuid check can be made after the vehicle has been sitting for eight hours or more with the engine off, but this is used only as a reference. Let the engine run at idle for ﬁve minutes if outside temperatures are 50°F (10°C) or more. If it is colder than 50°F (10°C), you may have to idle the engine longer. Should the ﬂuid level be low during this cold check, you must check the ﬂuid hot before adding ﬂuid. Checking the ﬂuid hot will give you a more accurate reading of the ﬂuid level. (cid:127) Checking the Fluid Level Prepare your vehicle as follows: 1. Park your vehicle on a level place. Keep the engine running. 2. With the parking brake applied, place the shift lever in PARK (P). 3. With your foot on the brake pedal, move the shift lever through each gear range, pausing for about three seconds in each range. Then, position the shift lever in PARK (P). 4. Let the engine run at idle for three minutes or more. Then, without shutting off the engine, follow these steps: 1. Flip the handle up and then pull out the dipstick and wipe it with a clean rag or paper towel. The automatic transmission dipstick handle with this symbol on it is located in the engine compartment on the passenger’s side of the vehicle. See Engine Compartment Overview on page 5-12 for more information on location. 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 in the COLD area, below the cross-hatched area, for a cold check or in the HOT or cross-hatched area for a hot check. Be sure to keep the dipstick pointed down to get an accurate reading. 4. If the ﬂuid level is in the acceptable range, push the dipstick back in all the way; then ﬂip the handle down to lock the dipstick in place. Consistency of Readings Always check the ﬂuid level at least twice using the procedure described previously. Consistency (repeatable readings) is important to maintaining proper ﬂuid level. If inconsistent readings persist, contact your dealer. 5-23 How to Add Automatic Transmission Fluid Refer to the Maintenance Schedule to determine what kind of transmission ﬂuid to use. See Recommended Fluids and Lubricants on page 6-12. Add ﬂuid only after checking the transmission ﬂuid while it is hot. A cold check is used only as a reference. If the ﬂuid level is low, add only enough of the proper ﬂuid to bring the level up to the HOT area for a hot check. It does not take much ﬂuid, generally less than one pint (0.5 L). Do not overﬁll. 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. (cid:127) After adding ﬂuid, recheck the ﬂuid level as described under “How to Check Automatic Transmission Fluid,” earlier in this section. (cid:127) When the correct ﬂuid level is obtained, push the dipstick back in all the way; then ﬂip the handle down to lock the dipstick in place. 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 5-27. A 50/50 mixture of clean, drinkable water and DEX-COOL® coolant will: (cid:127) Give freezing protection down to −34°F (−37°C). (cid:127) Give boiling protection up to 265°F (129°C). (cid:127) Protect against rust and corrosion. (cid:127) Help keep the proper engine temperature. 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. 5-24 (cid:127) What to Use Use a mixture of one-half clean, drinkable water and one-half DEX-COOL® coolant. 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. If you use an improper coolant mixture, your Notice: engine could overheat and be badly damaged. The repair cost would not be covered by your warranty. Too much water in the mixture can freeze and crack the engine, radiator, heater core and other parts. If you have to add coolant more than four times a year, have your dealer check your cooling system. Notice: 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 6-12 for more information. 5-25 Checking Coolant The engine coolant recovery tank is in the engine compartment on the passenger’s side of the vehicle. The cap has this symbol on it. See Engine Compartment Overview on page 5-12 for more information on location. {CAUTION: Turning the radiator pressure cap when the engine and radiator are hot can allow steam and scalding liquids to blow out and burn you badly. With the coolant recovery tank, you will almost never have to add coolant at the radiator. Never turn the radiator pressure cap — even a little — when the engine and radiator are hot. The vehicle must be on a level surface. When your engine is cold, the coolant level should be at FULL COLD, or a little higher. Adding Coolant If you need more coolant, add the proper DEX-COOL® coolant mixture at the coolant recovery tank. 5-26 Add coolant mixture at the recovery tank, but be careful not to spill it. {CAUTION: You can be burned if you spill coolant on hot engine parts. Coolant contains ethylene glycol, and it will burn if the engine parts are hot enough. Do not spill coolant on a hot engine. Occasionally check the coolant level in the radiator. For information on how to add coolant to the radiator, see Cooling System on page 5-29. If the pressure cap is not tightly installed, Radiator 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 5-12 for information on location. Engine Overheating You will ﬁnd a coolant temperature gage on your vehicle’s instrument panel. See Engine Coolant Temperature Gage on page 3-36 for more information. If your vehicle has a Driver Information Center (DIC), the display will show an Engine Coolant Hot/Engine Overheated message. See DIC Warnings and Messages on page 3-47 for more information. 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 you keep Notice: driving with no coolant, your vehicle can be badly damaged. The costly repairs would not be covered by your warranty. 5-27 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:127) Climb a long hill on a hot day. (cid:127) Stop after high-speed driving. Idle for long periods in traffic. Tow a trailer. If you get the overheat warning with no sign of steam, try this for a minute or so: 1. In heavy traffic, let the engine idle in NEUTRAL (N) while stopped. If it is safe to do so, pull off the road, shift to PARK (P) or NEUTRAL (N) and let the engine idle. 2. Turn on your heater to full hot at the highest fan speed and open the windows as necessary. If you no longer have the overheat warning, you can drive. Just to be safe, drive slower for about 10 minutes. If the warning does not come back on, you can drive normally. If the warning continues and you have not stopped, pull over, stop, and park your vehicle right away. If there is still no sign of steam, you can push down the accelerator until the engine speed is about twice as fast as normal idle speed for at least 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. 5-28 (cid:127) (cid:127) Cooling System When you decide it is safe to lift the hood, here is what you will see: 4.2L L6 Engine A. Coolant Recovery Tank B. Radiator Pressure Cap C. Engine Fan 5.3L V8 Engine A. Coolant Recovery Tank B. Radiator Pressure Cap C. Engine Fan If the coolant inside the coolant recovery tank is boiling, do not do anything else until it cools down. The vehicle should be parked on a level surface. 5-29 The coolant level should be at least up to the FULL COLD mark. 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. If there seems to be no leak, start the engine again. The engine cooling fan speed should increase when idle speed is doubled by pushing the accelerator pedal down. If it does 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 may 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. {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. 5-30 How to Add Coolant to the Coolant Recovery Tank If you have not found a problem yet, but the coolant level is not at the FULL COLD mark, add a 50/50 mixture of clean, drinkable water and DEX-COOL® engine coolant at the coolant recovery tank. See Engine Coolant on page 5-24 for more information. {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 crack Notice: 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. When the coolant in the coolant recovery tank is at the FULL COLD mark, start your vehicle. 5-31 If the overheat warning continues, there is one more thing you can try. You can add the proper coolant mixture directly to the radiator, but be sure the cooling system is cool before you do it. {CAUTION: Steam and scalding liquids from a hot cooling system can blow out and burn you badly. They are under pressure, and if you turn the radiator pressure cap — even a little — they can come out at high speed. Never turn the cap when the cooling system, including the radiator pressure cap, is hot. Wait for the cooling system and radiator pressure cap to cool if you ever have to turn the pressure cap. 5-32 How to Add Coolant to the Radiator 1. You can remove the radiator pressure cap when the cooling system, including the radiator pressure cap and upper radiator hose, is no longer hot. Turn the pressure cap slowly counterclockwise about one full turn. If you hear a hiss, wait for that to stop. A hiss means there is still some pressure left. 2. Then keep turning the pressure cap. Remove the pressure cap. 3. Fill the radiator with the proper DEX-COOL® coolant mixture, up to the base of the ﬁller neck. See Engine Coolant on page 5-24 for more information about the proper coolant mixture. 4. Then ﬁll the coolant recovery tank to the FULL COLD mark. 5. Put the cap back on the coolant recovery tank, but leave the radiator pressure cap off. 5-33 Engine Fan Noise Your vehicle has a clutched engine cooling fan. When the clutch is engaged, the fan spins faster to provide more air to cool the engine. In most everyday driving conditions the clutch is not engaged. This improves fuel economy and reduces fan noise. Under heavy vehicle loading, trailer towing, and/or high outside temperatures, the fan speed increases when the clutch engages so you may hear an increase in fan noise. This is normal and should not be mistaken as the transmission slipping or making extra shifts. It is merely the cooling system functioning properly. The fan will slow down when additional cooling is not required and the clutch disengages. You may also hear this fan noise when you start the engine. It will go away as the fan clutch disengages. 6. Start the engine and let it run until you can feel the upper radiator hose getting hot. Watch out for the engine cooling fan. 7. By this time, the coolant level inside the radiator ﬁller neck may be lower. If the level is lower, add more of the proper DEX-COOL® coolant mixture through the ﬁller neck until the level reaches the base of the ﬁller neck. 8. Then replace the pressure cap. At any time during this procedure if coolant begins to ﬂow out of the ﬁller neck, reinstall the pressure cap. Be sure the pressure cap is hand-tight and fully seated. 5-34 Power Steering Fluid See Engine Compartment Overview on page 5-12 for reservoir location. When to Check Power Steering Fluid It is not necessary to regularly check power steering ﬂuid unless you suspect there is a leak in the system or you hear an unusual noise. A ﬂuid loss in this system could indicate a problem. Have the system inspected and repaired. How to Check Power Steering Fluid To check the power steering ﬂuid, do the following: 1. Turn the key off and let the engine compartment cool down. 2. Wipe the cap and the top of the reservoir clean. 3. Unscrew the cap and wipe the dipstick with a clean rag. 4. Replace the cap and completely tighten it. 5. Remove the cap again and look at the ﬂuid level on the dipstick. For vehicles with the 4.2L L6 engine, the level should be at the C (Cold) mark. For vehicles with the 5.3L V8 engine, the level should be at the FULL mark. If necessary, add only enough ﬂuid to bring the level up to the mark. What to Use To determine what kind of ﬂuid to use, see Recommended Fluids and Lubricants on page 6-12. Always use the proper ﬂuid. Failure to use the proper ﬂuid can cause leaks and damage hoses and seals. 5-35 Windshield Washer Fluid What to Use When you need windshield washer ﬂuid, be sure to read the manufacturer’s instructions before use. If you will be operating your vehicle in an area where the temperature may fall below freezing, use a ﬂuid that has sufficient protection against freezing. Adding Washer Fluid Open the cap with the washer symbol on it. Add washer ﬂuid until the tank is full. See Engine Compartment Overview on page 5-12 for reservoir location. Notice: (cid:127) When using concentrated washer ﬂuid, follow the manufacturer’s instructions for adding water. (cid:127) Do not mix water with ready-to-use washer ﬂuid. Water can cause the solution to freeze and damage your washer ﬂuid tank and other parts of the washer system. Also, water does not clean as well as washer ﬂuid. Fill your washer ﬂuid tank only three-quarters full when it is very cold. This allows for expansion if freezing occurs, which could damage the tank if it is completely full. (cid:127) Do not use engine coolant (antifreeze) in your windshield washer. It can damage your washer system and paint. 5-36 (cid:127) Brakes Brake Fluid Your brake master cylinder reservoir is ﬁlled with DOT-3 brake ﬂuid. See Engine Compartment Overview on page 5-12 for the location of the reservoir. There are only two reasons why the brake ﬂuid level in the reservoir might go down. The ﬁrst is that the brake ﬂuid goes down to an acceptable level during normal brake lining wear. When new linings are put in, the ﬂuid level goes back up. The other reason is that ﬂuid is leaking out of the brake system. If it is, you should have your brake system ﬁxed, since a leak means that sooner or later your brakes will not work well, or will not work at all. So, it is not a good idea to top off your brake ﬂuid. Adding brake ﬂuid will not correct a leak. If you add ﬂuid when your linings are worn, then you will have too much ﬂuid when you get new brake linings. You should add or remove brake ﬂuid, as necessary, only when work is done on the brake hydraulic system. {CAUTION: If you have too much brake ﬂuid, it can spill on the engine. The ﬂuid will burn if the engine is hot enough. You or others could be burned, and your vehicle could be damaged. Add brake ﬂuid only when work is done on the brake hydraulic system. See “Checking Brake Fluid” in this section. Refer to the Maintenance Schedule to determine when to check your brake ﬂuid. See Scheduled Maintenance on page 6-4. 5-37 Checking Brake Fluid You can check the brake ﬂuid without taking off the cap. {CAUTION: Look at the brake ﬂuid reservoir. The ﬂuid level should be above MIN. If it is not, have your brake system checked to see if there is a leak. After work is done on the brake hydraulic system, make sure the level is above the MIN but not over the MAX mark. 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 6-12. 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. 5-38 With the wrong kind of ﬂuid in your brake system, your brakes may not work well, or they may not even work at all. This could cause a crash. Always use the proper brake ﬂuid. Notice: (cid:127) Using the wrong ﬂuid can badly damage brake system parts. For example, just a few drops of mineral-based oil, such as engine oil, in your brake system can damage brake system parts so badly that they will have to be replaced. Do not let someone put in the wrong kind of ﬂuid. If you spill brake ﬂuid on your vehicle’s painted surfaces, the paint ﬁnish can be damaged. Be careful not to spill brake ﬂuid on your vehicle. If you do, wash it off immediately. See Washing Your Vehicle on page 5-92. (cid:127) Brake Wear Your vehicle has four-wheel disc brakes. Disc brake pads have built-in wear indicators that make a high-pitched warning sound when the brake pads are worn and new pads are needed. The sound may come and go or be heard all the time your vehicle is moving, except when you are pushing on the brake pedal ﬁrmly. {CAUTION: The brake wear warning sound means that soon your brakes will not work well. That could lead to an accident. When you hear the brake wear warning sound, have your vehicle serviced. Notice: Continuing to drive with worn-out brake pads could result in costly brake repair. Some driving conditions or climates may cause a brake squeal when the brakes are ﬁrst applied or lightly applied. This does not mean something is wrong with your brakes. Properly torqued wheel nuts are necessary to help prevent brake pulsation. When tires are rotated, inspect brake pads for wear and evenly tighten wheel nuts in the proper sequence to torque speciﬁcations. Brake linings should always be replaced as complete axle sets. Brake Pedal Travel See your dealer if the brake pedal does not return to normal height, or if there is a rapid increase in pedal travel. This could be a sign of brake trouble. Brake Adjustment Every time you make a brake stop, your disc brakes adjust for wear. 5-39 Vehicle Storage If you are not going to drive your vehicle for 25 days or more, remove the black, negative (−) cable from the battery. This will help keep your battery from running down. {CAUTION: Batteries have acid that can burn you and gas that can explode. You can be badly hurt if you are not careful. See Jump Starting on page 5-41 for tips on working around a battery without getting hurt. 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 your braking system — for example, when your brake linings wear down and you need new ones put in — be sure you get new approved replacement parts. If you do not, your brakes may no longer work properly. For example, if someone puts in brake linings that are wrong for your vehicle, the balance between your front and rear brakes can change — for the worse. The braking performance you have come to expect can change in many other ways if someone puts in the wrong replacement brake parts. Battery Your vehicle has a maintenance free battery. When it is time for a new battery, get one that has the replacement number shown on the original battery’s label. We recommend an ACDelco® replacement battery. See Engine Compartment Overview on page 5-12 for battery location. Warning: Battery posts, terminals, and related accessories contain lead and lead compounds, chemicals known to the State of California to cause cancer and reproductive harm. Wash hands after handling. 5-40 Jump Starting If your vehicle’s battery has run down, you may want to use another vehicle and some jumper cables to start your vehicle. Be sure to use the following steps to do it safely. {CAUTION: Batteries can hurt you. They can be dangerous because: (cid:127) They contain acid that can burn you. (cid:127) They contain gas that can explode or (cid:127) They contain enough electricity to ignite. burn you. If you do not follow these steps exactly, some or all of these things can hurt you. Ignoring these steps could result in costly Notice: damage to your vehicle that would not be covered by your warranty. Trying to start your vehicle by pushing or pulling it will not work, and it could damage your vehicle. 1. Check the other vehicle. It must have a 12-volt battery with a negative ground system. Notice: If the other vehicle’s system is not a 12-volt system with a negative ground, both vehicles can be damaged. Only use vehicles with 12-volt systems with negative grounds to jump start your vehicle. 2. Get the vehicles close enough so the jumper cables can reach, but be sure the vehicles are not touching each other. If they are, it could cause a ground connection you do not want. You would not be able to start your vehicle, and the bad grounding could damage the electrical systems. To avoid the possibility of the vehicles rolling, set the parking brake ﬁrmly on both vehicles involved in the jump start procedure. Put an automatic transmission in PARK (P) or a manual transmission in NEUTRAL before setting the parking brake. If you have a four-wheel-drive vehicle, be sure the transfer case is not in NEUTRAL. 5-41 {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. 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 outlets, if equipped. Turn off the radio and all lamps that are not needed. This will avoid sparks and help to save both batteries. And it could save the radio! 4. Open both hoods and locate the batteries. Find the positive (+) and negative (−) terminals on each battery. Your vehicle has a remote negative (−) jump starting terminal. You should always use this remote terminal instead of the terminal on the battery. The remote negative (−) terminal is located on the front engine lift bracket on vehicles with the 4.2L L6 engine or the engine accessory drive bracket for vehicles with the 5.3L V8 engine, and is marked GND (Ground). See Engine Compartment Overview on page 5-12 for more information on location. 5-42 {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 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. 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. 5-43 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 the remote negative (−) terminal on the vehicle with the dead battery. Your vehicle has a remote negative (−) terminal, marked GND, for this purpose. 9. Connect the other end of the negative (−) cable to the remote negative (−) terminal on the vehicle with the dead battery. 10. Now start the vehicle with the good battery and run the engine for a while. 11. Try to start the vehicle that had the dead battery. If it will not start after a few tries, it probably needs service. If the jumper cables are connected or Notice: removed in the wrong order, electrical shorting may occur and damage the vehicle. The repairs would not be covered by your warranty. Always connect and remove the jumper cables in the correct order, making sure that the cables do not touch each other or other metal. 5.3L V8 Engine 4.2L L6 Engine The remote negative (−) terminal is located on the front engine lift bracket for the 4.2L L6 engine, and on the accessory drive bracket for the 5.3L V8 engine. 5-44 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. 3. Disconnect the red positive (+) cable from the vehicle with the good battery. 4. Disconnect the red positive (+) cable from the other vehicle. 5-45 All-Wheel Drive When to Check Lubricant It is not necessary to regularly check ﬂuid unless you suspect there is a leak or you hear an unusual noise. A ﬂuid loss could indicate a problem. Have it inspected and repaired. How to Check Lubricant 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. Use care not to overtighten the plug. What to Use To determine what kind of lubricant to use, see Recommended Fluids and Lubricants on page 6-12. To get an accurate reading, the vehicle should be on a level surface. 5-46 Rear Axle When to Check Lubricant It is not necessary to regularly check rear axle ﬂuid unless you suspect there is a leak or you hear an unusual noise. A ﬂuid loss could indicate a problem. Have it inspected and repaired. How to Check Lubricant The proper level is from 0 to 3/8 inch (0 to 10 mm) below the bottom of the ﬁller plug hole, located on the rear axle. What to Use To add lubricant when the level is low, use SAE 75W–90 Synthetic Axle Lubricant (GM Part No. U.S. 12378261, in Canada 10953455) meeting GM Speciﬁcation 9986115. To completely reﬁll after draining, add 4 ounces (118 ml) of Limited-Slip Axle Lubricant Additive (GM Part No. U.S. 1052358, in Canada 992694). Then ﬁll to the bottom of the ﬁller plug hole with the Synthetic Gear Lubricant. To get an accurate reading, the vehicle should be on a level surface. 5-47 Front Axle When to Check Lubricant It is not necessary to regularly check front axle ﬂuid unless you suspect there is a leak or you hear an unusual noise. A ﬂuid loss could indicate a problem. Have it inspected and repaired. How to Check Lubricant If the level is below the bottom of the ﬁller plug hole, located on the front axle, you may need to add some lubricant. When the differential is cold, add enough lubricant to raise the level to 1/2 inch (12 mm) below the ﬁller plug hole. When the differential is at operating temperature (warm), add enough lubricant to raise the level to the bottom of the ﬁller plug hole. What to Use To determine what kind of lubricant to use, see Recommended Fluids and Lubricants on page 6-12. To get an accurate reading, the vehicle should be on a level surface. 5-48 Headlamp Aiming Headlamp aim has been preset at the factory and should need no further adjustment. If your vehicle is damaged in an accident, the headlamp aim may be affected. Aim adjustment to the low-beam headlamps may be necessary if it is difficult to see the lane markers (for horizontal aim), or if oncoming drivers ﬂash their high-beam headlamps at you (for vertical aim). If you believe your headlamps need to be re-aimed, we recommend that you take your vehicle to your dealer for service. Bulb Replacement For the proper type of replacement bulbs, see Replacement Bulbs on page 5-53. For any bulb changing procedure not listed in this section, contact your dealer. High Intensity Discharge (HID) Lighting {CAUTION: The low beam high intensity discharge lighting system operates at a very high voltage. If you try to service any of the system components, you could be seriously injured. Have your dealer or a qualiﬁed technician service them. Your vehicle may have HID headlamps. After your vehicle’s HID headlamp bulb has been replaced, you may notice that the beam is a slightly different shade than it was originally.
