Glossary of tire terminology • Tire label: A label showing the OE (Original Equipment) tire sizes, recommended inflation pressure and the maximum weight the vehicle can carry. 220 2007 Expedition (exd) Owners Guide (post-2002-fmt) USA (fus) Tires, Wheels and Loading • Tire Identification Number (TIN): A number on the sidewall of each tire providing information about the tire brand and manufacturing plant, tire size and date of manufacture. Also referred to as DOT code. • Inflation pressure: A measure of the amount of air in a tire. • Standard load: A class of P-metric or Metric tires designed to carry a maximum load at 35 psi [37 psi (2.5 bar) for Metric tires]. Increasing the inflation pressure beyond this pressure will not increase the tire’s load carrying capability. • Extra load: A class of P-metric or Metric tires designed to carry a heavier maximum load at 41 psi [43 psi (2.9 bar) for Metric tires]. Increasing the inflation pressure beyond this pressure will not increase the tire’s load carrying capability. • kPa: Kilopascal, a metric unit of air pressure. • PSI: Pounds per square inch, a standard unit of air pressure. • Cold inflation pressure: The tire pressure when the vehicle has been stationary and out of direct sunlight for an hour or more and prior to the vehicle being driven for 1 mile (1.6 km). front door. • Recommended inflation pressure: The cold inflation pressure found on the Safety Compliance Certification Label or Tire Label located on the B-Pillar or the edge of the driver’s door. • B-pillar: The structural member at the side of the vehicle behind the • Bead area of the tire: Area of the tire next to the rim. • Sidewall of the tire: Area between the bead area and the tread. • Tread area of the tire: Area of the perimeter of the tire that • Rim: The metal support (wheel) for a tire or a tire and tube assembly contacts the road when mounted on the vehicle. upon which the tire beads are seated. INFLATING YOUR TIRES Safe operation of your vehicle requires that your tires are properly inflated. Remember that a tire can lose up to half of its air pressure without appearing flat. Every day before you drive, check your tires. If one looks lower than the others, use a tire gauge to check pressure of all tires and adjust if required. 221 2007 Expedition (exd) Owners Guide (post-2002-fmt) USA (fus) Tires, Wheels and Loading At least once a month and before long trips, inspect each tire and check the tire pressure with a tire gauge (including spare, if equipped). Inflate all tires to the inflation pressure recommended by Ford Motor Company. Use a tire gauge to check the tire inflation pressure, including the spare (if equipped), at least monthly and before long trips. You are strongly urged to buy a reliable tire pressure gauge, as automatic service station gauges may be inaccurate. Ford recommends the use of a digital or dial-type tire pressure gauge rather than a stick-type tire pressure gauge. Use the recommended cold inflation pressure for optimum tire performance and wear. Under-inflation or over-inflation may cause uneven treadwear patterns. Under-inflation is the most common cause of tire failures and may result in severe tire cracking, tread separation or ⬙blowout⬙, with unexpected loss of vehicle control and increased risk of injury. Under-inflation increases sidewall flexing and rolling resistance, resulting in heat buildup and internal damage to the tire. It also may result in unnecessary tire stress, irregular wear, loss of vehicle control and accidents. A tire can lose up to half of its air pressure and not appear to be flat! Always inflate your tires to the Ford recommended inflation pressure even if it is less than the maximum inflation pressure information found on the tire. The Ford recommended tire inflation pressure is found on the Safety Compliance Certification Label or Tire Label which is located on the B-Pillar or the edge of the driver’s door. Failure to follow the tire pressure recommendations can cause uneven treadwear patterns and adversely affect the way your vehicle handles. Maximum Permissible Inflation Pressure is the tire manufacturer’s maximum permissible pressure and/or the pressure at which the maximum load can be carried by the tire. This pressure is normally higher than the manufacturer’s recommended cold inflation pressure which can be found on the Safety Compliance Certification Label or Tire Label which is located on the B-Pillar or the edge of the driver’s door. The cold inflation pressure should never be set lower than the recommended pressure on the Safety Compliance Certification Label or Tire Label. When weather temperature changes occur, tire inflation pressures also change. A 10°F (6°C) temperature drop can cause a corresponding drop of 1 psi (7 kPa) in inflation pressure. Check your tire pressures frequently and adjust them to the proper pressure which can be found on the Safety Compliance Certification Label or Tire Label. 222 2007 Expedition (exd) Owners Guide (post-2002-fmt) USA (fus) Tires, Wheels and Loading To check the pressure in your tire(s): 1. Make sure the tires are cool, meaning they are not hot from driving even a mile. If you are checking tire pressure when the tire is hot, (i.e. driven more than 1 mile [1.6 km]), never “bleed” or reduce air pressure. The tires are hot from driving and it is normal for pressures to increase above recommended cold pressures. A hot tire at or below recommended cold inflation pressure could be significantly under-inflated. Note: If you have to drive a distance to get air for your tire(s), check and record the tire pressure first and add the appropriate air pressure when you get to the pump. It is normal for tires to heat up and the air pressure inside to go up as you drive. 2. Remove the cap from the valve on one tire, then firmly press the tire gauge onto the valve and measure the pressure. 3. Add enough air to reach the recommended air pressure. Note: If you overfill the tire, release air by pushing on the metal stem in the center of the valve. Then recheck the pressure with your tire gauge. 4. Replace the valve cap. 5. Repeat this procedure for each tire, including the spare. Note: Some spare tires operate at a higher inflation pressure than the other tires. For T-type/mini-spare tires (see Dissimilar Spare Tire/Wheel Information section for description): Store and maintain at 60psi (4.15 bar). For Full Size and Dissimilar spare tires (see Dissimilar Spare Tire/Wheel Information section for description): Store and maintain at the higher of the front and rear inflation pressure as shown on the Tire Label. 6. Visually inspect the tires to make sure there are no nails or other objects embedded that could poke a hole in the tire and cause an air leak. 7. Check the sidewalls to make sure there are no gouges, cuts or bulges. TIRE CARE Inspecting your tires Periodically inspect the tire treads for uneven or excessive wear and remove objects such as stones, nails or glass that may be wedged in the tread grooves. Check for holes or cuts that may permit air leakage from the tire and make necessary repairs. Also inspect the tire sidewalls for 223 2007 Expedition (exd) Owners Guide (post-2002-fmt) USA (fus) Tires, Wheels and Loading cracking, cuts, bruises and other signs of damage or excessive wear. If internal damage to the tire is suspected, have the tire demounted and inspected in case it needs to be repaired or replaced. For your safety, tires that are damaged or show signs of excessive wear should not be used because they are more likely to blow out or fail. Improper or inadequate vehicle maintenance can cause tires to wear abnormally. Inspect all your tires, including the spare, frequently, and replace them if one or more of the following conditions exist: Tire wear When the tread is worn down to 1/16th of an inch (2 mm), tires must be replaced to help prevent your vehicle from skidding and hydroplaning. Built-in treadwear indicators, or “wear bars”, which look like narrow strips of smooth rubber across the tread will appear on the tire when the tread is worn down to 1/16th of an inch (2 mm). When the tire tread wears down to the same height as these “wear bars”, the tire is worn out and must be replaced. Damage Periodically inspect the tire treads and sidewalls for damage (such as bulges in the tread or sidewalls, cracks in the tread groove and separation in the tread or sidewall). If damage is observed or suspected have the tire inspected by a tire professional. Tires can be damaged during off-road use, so inspection after off-road use is also recommended. Age Tires degrade over time depending on many factors such as weather, storage conditions, and conditions of use (load, speed, inflation pressure, etc.) the tires experience throughout their lives. In general, tires should be replaced after six years regardless of tread wear. However, heat caused by hot climates or frequent high loading conditions can accelerate the aging process and may require tires to be replaced more frequently. You should replace your spare tire when you replace the road tires or after six years due to aging even if it has not been used. 224 2007 Expedition (exd) Owners Guide (post-2002-fmt) USA (fus) Tires, Wheels and Loading U.S. DOT Tire Identification Number (TIN) Both U.S. and Canada Federal regulations require tire manufacturers to place standardized information on the sidewall of all tires. This information identifies and describes the fundamental characteristics of the tire and also provides a U.S. DOT Tire Identification Number for safety standard certification and in case of a recall. This begins with the letters “DOT” and indicates that the tire meets all federal standards. The next two numbers or letters are the plant code designating where it was manufactured, the next two are the tire size code and the last four numbers represent the week and year the tire was built. For example, the numbers 317 mean the 31st week of 1997. After 2000 the numbers go to four digits. For example, 2501 means the 25th week of 2001. The numbers in between are identification codes used for traceability. This information is used to contact customers if a tire defect requires a recall. Tire replacement requirements Your vehicle is equipped with tires designed to provide a safe ride and handling capability. Only use replacement tires and wheels that are the same size, load index, speed rating and type (such as P-metric versus LT-metric or all-season versus all-terrain) as those originally provided by Ford. The recommended tire and wheel size may be found on either the Safety Compliance Certification Label or the Tire Label which is located on the B-Pillar or edge of the driver’s door. If this information is not found on these labels then you should consult your Ford dealer. Use of any tire or wheel not recommended by Ford can affect the safety and performance of your vehicle, which could result in an increased risk of loss of vehicle control, vehicle rollover, personal injury and death. Additionally the use of non-recommended tires and wheels could cause steering, suspension, axle or transfer case/power transfer unit failure. If you have questions regarding tire replacement, see an authorized dealer. 225 2007 Expedition (exd) Owners Guide (post-2002-fmt) USA (fus) Tires, Wheels and Loading When mounting replacement tires and wheels, you should not exceed the maximum pressure indicated on the sidewall of the tire to set the beads without additional precautions listed below. If the beads do not seat at the maximum pressure indicated, re-lubricate and try again. When inflating the tire for mounting pressures up to 20 psi greater than the maximum pressure on the tire sidewall, the following precautions must be taken to protect the person mounting the tire: 1. Make sure that you have the correct tire and wheel size. 2. Lubricate the tire bead and wheel bead seat area again. 3. Stand at a minimum of 12 feet away from the tire wheel assembly. 4. Use both eye and ear protection. For a mounting pressure more than 20 psi greater than the maximum pressure, a Ford Dealer or other tire service professional should do the mounting. Always inflate steel carcass tires with a remote air fill with the person inflating standing at a minimum of 12 ft. away from the tire wheel assembly. Important: Remember to replace the wheel valve stems when the road tires are replaced on your vehicle. It is recommended that the two front tires or two rear tires generally be replaced as a pair. The tire pressure sensors mounted in the wheels (originally installed on your vehicle) are not designed to be used in aftermarket wheels. The use of wheels or tires not recommended by Ford Motor Company may affect the operation of your Tire Pressure Monitoring System. If the TPMS indicator is flashing, your TPMS is malfunctioning. Your replacement tire might be incompatible with your TPMS, or some component of the TPMS may be damaged. Safety practices Driving habits have a great deal to do with your tire mileage and safety. • Observe posted speed limits • Avoid fast starts, stops and turns • Avoid potholes and objects on the road • Do not run over curbs or hit the tire against a curb when parking 226 2007 Expedition (exd) Owners Guide (post-2002-fmt) USA (fus) Tires, Wheels and Loading If your vehicle is stuck in snow, mud, sand, etc., do not rapidly spin the tires; spinning the tires can tear the tire and cause an explosion. A tire can explode in as little as three to five seconds. Do not spin the wheels at over 35 mph (56 km/h). The tires may fail and injure a passenger or bystander. Highway hazards No matter how carefully you drive there’s always the possibility that you may eventually have a flat tire on the highway. Drive slowly to the closest safe area out of traffic. This may further damage the flat tire, but your safety is more important. If you feel a sudden vibration or ride disturbance while driving, or you suspect your tire or vehicle has been damaged, immediately reduce your speed. Drive with caution until you can safely pull off the road. Stop and inspect the tires for damage. If a tire is under-inflated or damaged, deflate it, remove wheel and replace it with your spare tire and wheel. If you cannot detect a cause, have the vehicle towed to the nearest repair facility or tire dealer to have the vehicle inspected. Tire and wheel alignment A bad jolt from hitting a curb or pothole can cause the front end of your vehicle to become misaligned or cause damage to your tires. If your vehicle seems to pull to one side when you’re driving, the wheels may be out of alignment. Have an authorized dealer check the wheel alignment periodically. Wheel misalignment in the front or the rear can cause uneven and rapid treadwear of your tires and should be corrected by an authorized dealer. Front wheel drive (FWD) vehicles and those with an independent rear suspension (if equipped) may require alignment of all four wheels. The tires should also be balanced periodically. An unbalanced tire and wheel assembly may result in irregular tire wear. Tire rotation Rotating your tires at the recommended interval (as indicated in the scheduled maintenance information that comes with your vehicle) will help your tires wear more evenly, providing better tire performance and longer tire life. Unless otherwise specified, rotate the tires approximately every 5,000 miles (8,000 km). 227 2007 Expedition (exd) Owners Guide (post-2002-fmt) USA (fus) Tires, Wheels and Loading • Rear Wheel Drive (RWD) vehicles/Four Wheel Drive (4WD)/ All Wheel Drive (AWD) vehicles (front tires at top of diagram) Sometimes irregular tire wear can be corrected by rotating the tires. Note: If your tires show uneven wear ask an authorized dealer to check for and correct any wheel misalignment, tire imbalance or mechanical problem involved before tire rotation. Note: Your vehicle may be equipped with a dissimilar spare tire/wheel. A dissimilar spare tire/wheel is defined as a spare tire and/or wheel that is different in brand, size or appearance from the road tires and wheels. If you have a dissimilar spare tire/wheel it is intended for temporary use only and should not be used in a tire rotation. Note: After having your tires rotated, inflation pressure must be checked and adjusted to the vehicle requirements. INFORMATION CONTAINED ON THE TIRE SIDEWALL Both U.S. and Canada Federal regulations require tire manufacturers to place standardized information on the sidewall of all tires. This information identifies and describes the fundamental characteristics of the tire and also provides a U.S. DOT Tire Identification Number for safety standard certification and in case of a recall. 228 2007 Expedition (exd) Owners Guide (post-2002-fmt) USA (fus) Tires, Wheels and Loading Information on “P” type tires P215/65R15 95H is an example of a tire size, load index and speed rating. The definitions of these items are listed below. (Note that the tire size, load index and speed rating for your vehicle may be different from this example.) 1. P: Indicates a tire, designated by the Tire and Rim Association (T&RA), that may be used for service on cars, SUVs, minivans and light trucks. Note: If your tire size does not begin with a letter this may mean it is designated by either ETRTO (European Tire and Rim Technical Organization) or JATMA (Japan Tire Manufacturing Association). 2. 215: Indicates the nominal width of the tire in millimeters from sidewall edge to sidewall edge. In general, the larger the number, the wider the tire. 3. 65: Indicates the aspect ratio which gives the tire’s ratio of height to width. 4. R: Indicates a “radial” type tire. 5. 15: Indicates the wheel or rim diameter in inches. If you change your wheel size, you will have to purchase new tires to match the new wheel diameter. 6. 95: Indicates the tire’s load index. It is an index that relates to how much weight a tire can carry. You may find this information in your Owner’s Guide. If not, contact a local tire dealer. Note: You may not find this information on all tires because it is not required by federal law. 7. H: Indicates the tire’s speed rating. The speed rating denotes the speed at which a tire is designed to be driven for extended periods of time under a standard condition of load and inflation pressure. The tires on your vehicle may operate at different conditions for load and inflation pressure. These speed ratings may need to be adjusted for the difference in conditions. The ratings range from 81 mph (130 km/h) to 186 mph (299 km/h). These ratings are listed in the following chart. 229 2007 Expedition (exd) Owners Guide (post-2002-fmt) USA (fus) Tires, Wheels and Loading Note: You may not find this information on all tires because it is not required by federal law. Letter rating Speed rating - mph (km/h) 81 mph (130 km/h) 87 mph (140 km/h) 99 mph (159 km/h) 106 mph (171 km/h) 112 mph (180 km/h) 118 mph (190 km/h) 124 mph (200 km/h) 130 mph (210 km/h) 149 mph (240 km/h) 168 mph (270 km/h) 186 mph (299 km/h) Note: For tires with a maximum speed capability over 149 mph (240 km/h), tire manufacturers sometimes use the letters ZR. For those with a maximum speed capability over 186 mph (299 km/h), tire manufacturers always use the letters ZR. 8. U.S. DOT Tire Identification Number (TIN): This begins with the letters “DOT” and indicates that the tire meets all federal standards. The next two numbers or letters are the plant code designating where it was manufactured, the next two are the tire size code and the last four numbers represent the week and year the tire was built. For example, the numbers 317 mean the 31st week of 1997. After 2000 the numbers go to four digits. For example, 2501 means the 25th week of 2001. The numbers in between are identification codes used for traceability. This information is used to contact customers if a tire defect requires a recall. 9. M+S or M/S: Mud and Snow, or AT: All Terrain, or AS: All Season. 10. Tire Ply Composition and Material Used: Indicates the number of plies or the number of layers of rubber-coated fabric in the tire tread and sidewall. Tire manufacturers also must indicate the ply materials in the tire and the sidewall, which include steel, nylon, polyester, and others. 11. Maximum Load: Indicates the maximum load in kilograms and pounds that can be carried by the tire. Refer to the Safety Compliance Certification Label, which is located on the B-Pillar or the edge of the driver’s door, for the correct tire pressure for your vehicle. 230 2007 Expedition (exd) Owners Guide (post-2002-fmt) USA (fus) Tires, Wheels and Loading 12. Treadwear, Traction and Temperature Grades • 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 one-half (11⁄2) times as well on the government course as a tire graded 100. • Traction: The traction grades, from highest to lowest are AA, A, B, and C. The 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. • Temperature: 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. 13. Maximum Permissible Inflation Pressure: Indicates the tire manufacturers’ maximum permissible pressure and/or the pressure at which the maximum load can be carried by the tire. This pressure is normally higher than the manufacturer’s recommended cold inflation pressure which can be found on the Safety Compliance Certification Label or Tire Label which is located on the B-Pillar or the edge of the driver’s door. The cold inflation pressure should never be set lower than the recommended pressure on the vehicle label. The tire suppliers may have additional markings, notes or warnings such as standard load, radial tubeless, etc. 231 2007 Expedition (exd) Owners Guide (post-2002-fmt) USA (fus) Tires, Wheels and Loading Additional information contained on the tire sidewall for “LT” type tires “LT” type tires have some additional information beyond those of “P” type tires; these differences are described below: 1. LT: Indicates a tire, designated by the Tire and Rim Association (T&RA), that is intended for service on light trucks. 2. Load Range/Load Inflation Limits: Indicates the tire’s load-carrying capabilities and its inflation limits. 3. Maximum Load Dual lb. (kg) at psi (kPa) cold: Indicates the maximum load and tire pressure when the tire is used as a dual; defined as four tires on the rear axle (a total of six or more tires on the vehicle). 4. Maximum Load Single lb. (kg) at psi (kPa) cold: Indicates the maximum load and tire pressure when the tire is used as a single; defined as two tires (total) on the rear axle. 232 2007 Expedition (exd) Owners Guide (post-2002-fmt) USA (fus) Tires, Wheels and Loading Information on “T” type tires “T” type tires have some additional information beyond those of “P” type tires; these differences are described below: T145/80D16 is an example of a tire size. Note: The temporary tire size for your vehicle may be different from this example. 1. T: Indicates a type of tire, designated by the Tire and Rim Association (T&RA), that is intended for temporary service on cars, SUVs, minivans and light trucks. 2. 145: Indicates the nominal width of the tire in millimeters from sidewall edge to sidewall edge. In general, the larger the number, the wider the tire. 3. 80: Indicates the aspect ratio which gives the tire’s ratio of height to width. Numbers of 70 or lower indicate a short sidewall. 4. D: Indicates a “diagonal” type tire. R: Indicates a “radial” type tire. 5. 16: Indicates the wheel or rim diameter in inches. If you change your wheel size, you will have to purchase new tires to match the new wheel diameter. Location of the tire label You will find a Tire Label containing tire inflation pressure by tire size and other important information located on the B-Pillar or the edge of the driver’s door. Refer to the payload description and graphic in the Vehicle loading — with and without a trailer section. 233 2007 Expedition (exd) Owners Guide (post-2002-fmt) USA (fus) Tires, Wheels and Loading TIRE PRESSURE MONITORING SYSTEM (TPMS) Each tire, including the spare (if provided), should be checked monthly when cold and inflated to the inflation pressure recommended by the vehicle manufacturer on the vehicle placard or tire inflation pressure label. (If your vehicle has tires of a different size than the size indicated on the vehicle placard or tire inflation pressure label, you should determine the proper tire inflation pressure for those tires.) As an added safety feature, your vehicle has been equipped with a tire pressure monitoring system (TPMS) that illuminates a low tire pressure telltale when one or more of your tires is significantly under-inflated. Accordingly, when the low tire pressure telltale illuminates, you should stop and check your tires as soon as possible, and inflate them to the proper pressure. Driving on a significantly under-inflated tire causes the tire to overheat and can lead to tire failure. Under-inflation also reduces fuel efficiency and tire tread life, and may affect the vehicle’s handling and stopping ability. Please note that the TPMS is not a substitute for proper tire maintenance, and it is the driver’s responsibility to maintain correct tire pressure, even if under-inflation has not reached the level to trigger illumination of the TPMS low tire pressure telltale. The Tire Pressure Monitoring System complies with part 15 of the FCC rules and with RSS-210 of Industry Canada. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) This device must accept any interference received, including interference that may cause undesired operation. The Tire Pressure Monitoring System is NOT a substitute for manually checking tire pressure. The tire pressure should be checked periodically (at least monthly) using a tire gauge, see Inflating your tires in this chapter. Failure to properly maintain your tire pressure could increase the risk of tire failure, loss of control, vehicle rollover and personal injury. 234 2007 Expedition (exd) Owners Guide (post-2002-fmt) USA (fus) Tires, Wheels and Loading Changing tires with TPMS Each road tire is equipped with a tire pressure sensor fastened to the inside rim of the wheel. The pressure sensor is covered by the tire and is not visible unless the tire is removed. The pressure sensor is located opposite (180 degrees) from the valve stem. Care must be taken when changing the tire to avoid damaging the sensor. It is recommended that you always have your tires serviced by an authorized dealer. The tire pressure should be checked periodically (at least monthly) using an accurate tire gauge, refer to Inflating your tires in this chapter. Understanding your Tire Pressure Monitoring System (TPMS) The Tire Pressure Monitoring System measures pressure in your four road tires and sends the tire pressure readings to your vehicle. The Low Tire Warning Lamp will turn ON if the tire pressure is significantly low. Once the light is illuminated, your tires are under inflated and need to be inflated to the manufacturer’s recommended tire pressure. Even if the light turns ON and a short time later turns OFF, your tire pressure still needs to be checked. When your temporary spare tire is installed When one of your road tires needs to be replaced with the temporary spare, the TPMS system will continue to identify an issue to remind you that the damaged road wheel/tire needs to be repaired and put back on your vehicle. To restore the full functionality of the Tire Pressure Monitoring System, have the damaged road wheel/tire repaired and remounted on your vehicle. For additional information, refer to Changing tires with TPMS in this section. When you believe your system is not operating properly The main function of the Tire Pressure Monitoring System is to warn you when your tires need air. It can also warn you in the event the system is 235 2007 Expedition (exd) Owners Guide (post-2002-fmt) USA (fus) Tires, Wheels and Loading no longer capable of functioning as intended. Please refer to the following chart for information concerning your Tire Pressure Monitoring System: Low Tire Pressure Warning Light Solid Warning Light Tire(s) Possible cause Customer Action Required under-inflated 1. Check your tire pressure to ensure tires are properly inflated; refer to Inflating your tires in this chapter. 2. After inflating your tires to the manufacturer’s recommended inflation pressure as shown on the Tire Label (located on the edge of driver’s door or the B-Pillar), the vehicle must be driven for at least two minutes over 20 mph (32 km/h) before the light will turn OFF. Spare tire in use Your temporary spare tire is in use. Repair the damaged road wheel/tire and reinstall it on the vehicle to restore system functionality. For a description on how the system functions, refer to When your temporary spare tire is installed in this section. If your tires are properly inflated and your spare tire is not in use and the light remains ON, have the system inspected by your authorized dealer. TPMS malfunction 236 2007 Expedition (exd) Owners Guide (post-2002-fmt) USA (fus) Low Tire Pressure Warning Light Flashing Warning Light Tires, Wheels and Loading Possible cause Customer Action Required Spare tire in use Your temporary spare tire is in use. Repair the damaged road wheel and re-mount it on the vehicle to restore system functionality. For a description of how the system functions under these conditions, refer to When your temporary spare tire is installed in this section. If your tires are properly inflated and your spare tire is not in use and the TPMS warning light is still ON, have the system inspected by your authorized dealer. TPMS malfunction When inflating your tires When putting air into your tires (such as at a gas station or in your garage), the Tire Pressure Monitoring System may not respond immediately to the air added to your tires. It may take up to two minutes of driving over 20 mph (32 km/h) for the light to turn OFF after you have filled your tires to the recommended inflation pressure. How temperature affects your tire pressure The Tire Pressure Monitoring System (TPMS) monitors tire pressure in each pneumatic tire. While driving in a normal manner, a typical passenger tire inflation pressure may increase approximately 2 to 4 psi (14 to 28 kPa) from a cold start situation. If the vehicle is stationary over night with the outside temperature significantly lower than the daytime temperature, the tire pressure may decrease approximately 3 psi (20.7 kPa) for a drop of 30° F (16.6°C) in ambient temperature. This lower pressure value may be detected by the TPMS as being significantly lower than the recommended inflation pressure and activate the TPMS warning for low tire pressure. If the low tire pressure warning light is ON, visually check each tire to verify that no tire is flat. (If one or more tires are flat, repair as necessary.) Check air pressure in the road tires. If 237 2007 Expedition (exd) Owners Guide (post-2002-fmt) USA (fus) Tires, Wheels and Loading any tire is under-inflated, carefully drive the vehicle to the nearest location where air can be added to the tires. Inflate all the tires to the recommended inflation pressure. SNOW TIRES AND CHAINS Snow tires must be the same size and grade as the tires you currently have on your vehicle. The tires on your vehicle have all weather treads to provide traction in rain and snow. However, in some climates, you may need to use snow tires and chains. If you need to use chains, it is recommended that steel wheels (of the same size and specifications) be used, as chains may chip aluminum wheels. Follow these guidelines when using snow tires and chains: • Use only cable type chains or chains offered by Ford as an accessory or equivalent. Other conventional link type chains may contact and cause damage to the vehicle’s wheel house and/or body. • Do not install chains on the front wheels. Chains on the front wheels • Chains are not recommended for use on the P275/55R20 tire. • Install chains securely, verifying that the chains do not touch any • Drive cautiously. If you hear the chains rub or bang against your may interfere with suspension components. wiring, brake lines or fuel lines. vehicle, stop and re-tighten the chains. If this does not work, remove the chains to prevent damage to your vehicle. tire chains on dry roads. • If possible, avoid fully loading your vehicle. • Remove the tire chains when they are no longer needed. Do not use • The suspension insulation and bumpers will help prevent vehicle damage. Do not remove these components from your vehicle when using snow tires and chains. • Do not exceed 30 mph (48 km/h) with tire chains on your vehicle. VEHICLE LOADING – WITH AND WITHOUT A TRAILER This section will guide you in the proper loading of your vehicle and/or trailer, to keep your loaded vehicle weight within its design rating capability, with or without a trailer. Properly loading your vehicle will provide maximum return of vehicle design performance. Before loading 238 2007 Expedition (exd) Owners Guide (post-2002-fmt) USA (fus) Tires, Wheels and Loading your vehicle, familiarize yourself with the following terms for determining your vehicle’s weight ratings, with or without a trailer, from the vehicle’s Tire Label or Safety Compliance Certification Label: Base Curb Weight – is the weight of the vehicle including a full tank of fuel and all standard equipment. It does not include passengers, cargo, or optional equipment. Vehicle Curb Weight – is the weight of your new vehicle when you picked it up from your authorized dealer plus any aftermarket equipment. Payload – is the combined weight of cargo and passengers that the vehicle is carrying. The maximum payload for your vehicle can be found on the Tire Label on the B-Pillar or the edge of the driver’s door (vehicles exported outside the US and Canada may not have a Tire Label). Look for “THE COMBINED WEIGHT OF OCCUPANTS AND CARGO SHOULD NEVER EXCEED XXX kg OR XXX lb.” for maximum payload. The payload listed on the Tire Label is the maximum payload for the vehicle as built by the assembly plant. If any aftermarket or authorized-dealer installed equipment has been installed on the vehicle, the weight of the equipment must be subtracted from the payload listed on the Tire Label in order to determine the new payload. The appropriate loading capacity of your vehicle can be limited either by volume capacity (how much space is available) or by payload capacity (how much weight the vehicle should carry). Once you have reached the maximum payload of your vehicle, do not add more cargo, even if there is space available. Overloading or improperly loading your vehicle can contribute to loss of vehicle control and vehicle rollover. 239 2007 Expedition (exd) Owners Guide (post-2002-fmt) USA (fus) Tires, Wheels and Loading Example only: Cargo Weight – includes all weight added to the Base Curb Weight, including cargo and optional equipment. When towing, trailer tongue load or king pin weight is also part of cargo weight. GAW (Gross Axle Weight) – is the total weight placed on each axle (front and rear) – including vehicle curb weight and all payload. 240 2007 Expedition (exd) Owners Guide (post-2002-fmt) USA (fus) Tires, Wheels and Loading GAWR (Gross Axle Weight Rating) – is the maximum allowable weight that can be carried by a single axle (front or rear). These numbers are shown on the Safety Compliance Certification Label located on the B-Pillar or the edge of the driver’s door. The total load on each axle must never exceed its GAWR. Note: For trailer towing information refer to Trailer towing found in this chapter or the RV and Trailer Towing Guide provided by your authorized dealer. GVW (Gross Vehicle Weight) – is the Vehicle Curb Weight + cargo + passengers. GVWR (Gross Vehicle Weight Rating) – is the maximum allowable weight of the fully loaded vehicle (including all options, equipment, passengers and cargo). The GVWR is shown on the Safety Compliance Certification Label located on the B-Pillar or the edge of the driver’s door. The GVW must never exceed the GVWR. Exceeding the Safety Compliance Certification Label vehicle weight rating limits could result in substandard vehicle handling or performance, engine, transmission and/or structural damage, serious damage to the vehicle, loss of control and personal injury. 241 2007 Expedition (exd) Owners Guide (post-2002-fmt) USA (fus) Tires, Wheels and Loading GCW (Gross Combined Weight) – is the weight of the loaded vehicle (GVW) plus the weight of the fully loaded trailer. GCWR (Gross Combined Weight Rating) – is the maximum allowable weight of the vehicle and the loaded trailer – including all cargo and passengers – that the vehicle can handle without risking damage. (Important: The towing vehicle’s braking system is rated for operation at GVWR, not at GCWR.) Separate functional brakes should be used for safe control of towed vehicles and for trailers where the GCW of the towing vehicle plus the trailer exceed the GVWR of the towing vehicle. The GCW must never exceed the GCWR. Maximum Loaded Trailer Weight – is the highest possible weight of a fully loaded trailer the vehicle can tow. It assumes a vehicle with only mandatory options, no cargo (internal or external), a tongue load of 10–15% (conventional trailer) or king pin weight of 15–25% (fifth wheel trailer), and driver only (150 lb. [68 kg]). Consult your authorized dealer (or the RV and Trailer Towing Guide provided by your authorized dealer) for more detailed information. Tongue Load or Fifth Wheel King Pin Weight – refers to the amount of the weight that a trailer pushes down on a trailer hitch. Examples: For a 5,000 lb. (2,268 kg) conventional trailer, multiply 5,000 by 0.10 and 0.15 to obtain a proper tongue load range of 500 to 750 lb. (227 to 340 kg). For an 11,500 lb. (5,216 kg) fifth wheel trailer, multiply by 0.15 and 0.25 to obtain a proper king pin load range of 1,725 to 2,875 lb. (782 to 1,304 kg) Do not exceed the GVWR or the GAWR specified on the Safety Compliance Certification Label. Do not use replacement tires with lower load carrying capacities than the original tires because they may lower the vehicle’s GVWR and GAWR limitations. Replacement tires with a higher limit than the original tires do not increase the GVWR and GAWR limitations. 242 2007 Expedition (exd) Owners Guide (post-2002-fmt) USA (fus) Tires, Wheels and Loading Exceeding any vehicle weight rating limitation could result in serious damage to the vehicle and/or personal injury. Steps for determining the correct load limit: 1. Locate the statement “The combined weight of occupants and cargo should never exceed XXX kg or XXX lbs.” on your vehicle’s placard. 2. Determine the combined weight of the driver and passengers that will be riding in your vehicle. 3. Subtract the combined weight of the driver and passengers from XXX kg or XXX lbs. 4. The resulting figure equals the available amount of cargo and luggage load capacity. For example, if the “XXX” amount equals 1,400 lbs. and there will be five 150 lb. passengers in your vehicle, the amount of available cargo and luggage load capacity is 650 lbs. (1400-750 (5 x 150) = 650 lb.). In metric units (635-340 (5 x 68) = 295 kg.) 5. Determine the combined weight of luggage and cargo being loaded on the vehicle. That weight may not safely exceed the available cargo and luggage load capacity calculated in Step 4. 6. If your vehicle will be towing a trailer, load from your trailer will be transferred to your vehicle. Consult this manual to determine how this reduces the available cargo and luggage load capacity of your vehicle. The following gives you a few examples on how to calculate the available amount of cargo and luggage load capacity: • Another example for your vehicle with 1400 lb. (635 kg) of cargo and luggage capacity. You decide to go golfing. Is there enough load capacity to carry you, 4 of your friends and all the golf bags? You and four friends average 220 lb. (99 kg) each and the golf bags weigh approximately 30 lb. (13.5 kg) each. The calculation would be: 1400 - (5 x 220) - (5 x 30) = 1400 - 1100 - 150 = 150 lb. Yes, you have enough load capacity in your vehicle to transport four friends and your golf bags. In metric units, the calculation would be: 635 kg - (5 x 99 kg) - (5 x 13.5 kg) = 635 - 495 - 67.5 = 72.5 kg. • A final example for your vehicle with 1400 lb. (635 kg) of cargo and luggage capacity. You and one of your friends decide to pick up cement from the local home improvement store to finish that patio you have been planning for the past 2 years. Measuring the inside of the vehicle with the rear seat folded down, you have room for 12-100 lb. (45 kg) bags of cement. Do you have enough load capacity to 243 2007 Expedition (exd) Owners Guide (post-2002-fmt) USA (fus) Tires, Wheels and Loading transport the cement to your home? If you and your friend each weigh 220 lb. (99 kg), the calculation would be: 1400 - (2 x 220) - (12 x 100) = 1400 - 440 - 1200 = - 240 lb. No, you do not have enough cargo capacity to carry that much weight. In metric units, the calculation would be: 635 kg - (2 x 99 kg) - (12 x 45 kg) = 635 - 198 - 540 = -103 kg. You will need to reduce the load weight by at least 240 lb. (104 kg). If you remove 3-100 lb. (45 kg) cement bags, then the load calculation would be: 1400 - (2 x 220) - (9 x 100) = 1400 - 440 - 900 = 60 lb. Now you have the load capacity to transport the cement and your friend home. In metric units, the calculation would be: 635 kg - (2 x 99 kg) - (9 x 45 kg) = 635 - 198 - 405 = 32 kg. The above calculations also assume that the loads are positioned in your vehicle in a manner that does not overload the Front or the Rear Gross Axle Weight Rating specified for your vehicle on the Safety Compliance Certification Label found on the edge of the driver’s door. Special loading instructions for owners of pickup trucks and utility-type vehicles For important information regarding safe operation of this type of vehicle, see the Preparing to drive your vehicle section in the Driving chapter of this owner guide. Loaded vehicles, with a higher center of gravity, may handle differently than unloaded vehicles. Extra precautions, such as slower speeds and increased stopping distance, should be taken when driving a heavily loaded vehicle. Your vehicle has the capability to haul more cargo and people than most passenger cars. Depending upon the type and placement of the load, hauling cargo and people may raise the center of gravity of the vehicle. TRAILER TOWING Trailer towing puts additional loads on your vehicle’s engine, transmission, axle, brakes, tires, and suspension. For your safety and to maximize vehicle performance, be sure to use the proper equipment while towing. Follow these guidelines to ensure safe towing procedure: • Stay within your vehicle’s load limits. If exceeded, cargo should be removed from the trailer and/or the vehicle until all weights are within specified limits. 244 2007 Expedition (exd) Owners Guide (post-2002-fmt) USA (fus) tow in this chapter. Tires, Wheels and Loading • Thoroughly prepare your vehicle for towing. Refer to Preparing to • Use extra caution when driving while trailer towing.

Additionally, during the first 500 miles (800 km) that you tow a trailer, do not drive over 70 mph (112 km/h) and do not make starts at full throttle. • Refer to the instructions included with towing accessories for the proper installation and adjustment specifications. Trailer towing (standard equipment): Your vehicle is equipped with a integrated trailer hitch and a Class I (4-pin) trailer electrical connector. The 4-pin connector supplies power to tail lamps, stop lamps, and turn lamps. See the trailer towing chart for the trailer towing weight recommendation. Trailer towing (optionally equipped trailer tow package): The optional trailer tow package includes heavy duty trailer tow wiring. Both a Class I (4-pin) and IV (7-pin) trailer electrical connector are provided. Under the instrument panel a electrical connector is provided for a customer supplied aftermarket electronic brake controller. For installing a customer supplied electronic brake controller, a electrical jumper harness and trailer tow electrical instructions are included with the optional trailer tow package. The kit containing a electrical jumper and trailer tow electrical instructions may be purchased from any authorized dealer (Part number 4L1Z-14A348-AA) Note: Before towing a trailer, make sure the trailer brakes (if equipped) and lamps are properly connected and functional. Electronic trailer brakes (if equipped) refer to the instructions provided by the aftermarket electronic brake controller manufacture for determining trailer brake functionality. 245 2007 Expedition (exd) Owners Guide (post-2002-fmt) USA (fus) Tires, Wheels and Loading Rear axle Maximum GCWR - ratio lb.

Do not exceed the maximum loads listed on the Safety Compliance Certification label. For load specification terms found on the label, refer to Vehicle loading in this chapter. Remember to figure in the tongue load of your loaded trailer when figuring the total weight. Towing trailers beyond the maximum recommended gross trailer weight exceeds the limit of the vehicle and could result in engine damage, transmission damage, structural damage, loss of control, vehicle rollover and personal injury. 247 2007 Expedition (exd) Owners Guide (post-2002-fmt) USA (fus) Tires, Wheels and Loading Integrated hitch rating The standard integrated hitch has two ratings depending on mode of operation: • Weight carrying - requires a draw bar and hitch ball. The draw bar • Weight distributing - requires an aftermarket weight distributing system which includes draw bar, hitch ball, spring bars and snap-up brackets. The vertical tongue load of the trailer is distributed between the truck and the trailer by this system. supports all the vertical tongue load of the trailer. Mode Maximum Gross Trailer Weight - lb. Maximum Tongue Weight - lb. (kg) (kg) 600 (272) Weight carrying Weight distributing 910 (412) These are hitch ratings only; actual vehicle ratings are dependent on engine, transmission and axle combinations. 6000 (2721) 9100 (4127) Towing trailers beyond the maximum tongue weight exceeds the limit of the towing system and could result in vehicle structural damage, loss of vehicle control and personal injury. Preparing to tow Use the proper equipment for towing a trailer and make sure it is properly attached to your vehicle. See your authorized dealer or a reliable trailer dealer if you require assistance. Hitches Do not use hitches that clamp onto the vehicle’s bumper or attach to the axle. You must distribute the load in your trailer so that 10%–15% of the total weight of the trailer is on the tongue. Weight distributing hitch When hooking up a trailer using a load equalizing hitch, always use the following procedure: 1. Park the unloaded vehicle on a level surface. With the ignition in the ON position and all doors closed, allow the vehicle to stand (without passengers) for several minutes so that it can level. 248 2007 Expedition (exd) Owners Guide (post-2002-fmt) USA (fus) Tires, Wheels and Loading 2. Turn the air suspension (if equipped) control to OFF. 3. Measure the height of a reference point on the front and rear bumpers at the center of the vehicle. 4. Attach the trailer to the vehicle and adjust the hitch equalizers so that the front bumper height is within a 1⁄2” (13 mm) of the reference point. After proper adjustment, the rear bumper should be no higher than in Step 3. 5. Turn the air suspension (if equipped) control to ON. Note: Adjusting a weight distributing hitch so the rear bumper of the vehicle is higher than it was unloaded will defeat the function of the weight distributing hitch and may cause unpredictable handling. Safety chains Always connect the trailer’s safety chains to the frame or hook retainers of the vehicle hitch. To connect the trailer’s safety chains, cross the chains under the trailer tongue and allow slack for turning corners. If you use a rental trailer, follow the instructions that the rental agency gives to you. Do not attach safety chains to the bumper. Trailer brakes Electric brakes and manual, automatic or surge-type trailer brakes are safe if installed properly and adjusted to the manufacturer’s specifications. The trailer brakes must meet local and Federal regulations. Do not connect a trailer’s hydraulic brake system directly to your vehicle’s brake system. Your vehicle may not have enough braking power and your chances of having a collision greatly increase. The braking system of the tow vehicle is rated for operation at the GVWR not GCWR. Trailer lamps Trailer lamps are required on most towed vehicles. Make sure all running lights, brake lights, turn signals and hazard lights are working. See your authorized dealer or trailer rental agency for proper instructions and equipment for hooking up trailer lamps. 249 2007 Expedition (exd) Owners Guide (post-2002-fmt) USA (fus) Tires, Wheels and Loading Driving while you tow When towing a trailer: • Keep your speed no faster than 70 mph (112 km/h) during the first 500 miles (800 km) of towing a trailer, and don’t make full throttle starts. • Turn off the speed control. The speed control may shut off automatically when you are towing on long, steep grades. • Consult your local motor vehicle speed regulations for towing a trailer. • To eliminate excessive shifting, use a lower gear. This will also assist in transmission cooling. (For additional information, refer to Driving with a 6-speed automatic transmission in the Driving chapter. • Anticipate stops and brake gradually. • Do not exceed the GCWR rating or transmission damage may occur. If your vehicle is equipped with AdvanceTrac威 with RSC, you may experience AdvanceTrac威 with RSC activations during typical cornering maneuvers with a heavily loaded trailer; this is normal. Cornering at a slower speed while towing will reduce the tendency of the AdvanceTrac威 stability enhancement system to activate. Servicing after towing If you tow a trailer for long distances, your vehicle will require more frequent service intervals. Refer to your Scheduled Maintenance Information for more information. Trailer towing tips • Practice turning, stopping and backing up before starting on a trip to get the feel of the vehicle trailer combination. When turning, make wider turns so the trailer wheels will clear curbs and other obstacles. • Allow more distance for stopping with a trailer attached. • If you are driving down a long or steep hill, shift to a lower gear. Do not apply the brakes continuously, as they may overheat and become less effective. • The trailer tongue weight should be 10–15% of the loaded trailer • If you will be towing a trailer frequently in hot weather, hilly weight. conditions, at GCWR, or any combination of these factors, consider refilling your rear axle with synthetic gear lube if not already so equipped. Refer to the Maintenance and Specifications chapter for 250 2007 Expedition (exd) Owners Guide (post-2002-fmt) USA (fus) Tires, Wheels and Loading the lubricant specification. Remember that regardless of the rear axle lube used, do not tow a trailer for the first 500 miles (800 km) of a new vehicle, and that the first 500 miles (800 km) of towing be done at no faster than 70 mph (112 km/h) with no full throttle starts. • After you have traveled 50 miles (80 km), thoroughly check your • To aid in engine/transmission cooling and A/C efficiency during hot • Vehicles with trailers should not be parked on a grade.

Launching or retrieving a boat Disconnect the wiring to the trailer before backing the trailer into the water. Reconnect the wiring to the trailer after the trailer is removed from the water. When backing down a ramp during boat launching or retrieval: • do not allow the static water level to rise above the bottom edge of • do not allow waves to break higher than 6 inches (15 cm) above the the rear bumper. bottom edge of the rear bumper. Exceeding these limits may allow water to enter vehicle components: • causing internal damage to the components. • affecting driveability, emissions and reliability. Replace the rear axle lubricant any time the axle has been submerged in water. Rear axle lubricant quantities are not to be checked or changed unless a leak is suspected or repair required. RECREATIONAL TOWING (ALL WHEELS ON THE GROUND) An example of recreational towing would be towing your vehicle behind a motorhome. Follow these guidelines if you have the need for recreational towing your vehicle with all four wheels on the ground. These guidelines are designed to ensure that your transmission is not damaged. 2WD vehicles (with automatic transmissions): • Place the transmission in N (Neutral) • Maximum speed is 35 mph (56 km/h) • Maximum distance is 50 miles (80 km) 251 2007 Expedition (exd) Owners Guide (post-2002-fmt) USA (fus) Tires, Wheels and Loading If a distance of 50 miles (80 km) or a speed of 35 mph (56 km/h) must be exceeded, the drive shaft will have to be removed before the vehicle is towed. Ford recommends the driveshaft be removed/installed only by a qualified technician at an authorized dealer. See your authorized dealer for driveshaft removal/installation. Improper removal/installation of the driveshaft can cause transmission fluid loss, damage to the driveshaft and internal transmission components. Vehicles equipped with Control Trac four-wheel drive system: Vehicles equipped with the Control Trac four-wheel drive system cannot be towed with any wheels on the ground. See your authorized dealer if you must flat-tow a vehicle equipped with the Control Trac four-wheel drive system. 252 2007 Expedition (exd) Owners Guide (post-2002-fmt) USA (fus) Driving STARTING Positions of the ignition 1. OFF/LOCK, locks the steering wheel, automatic transmission gearshift lever and allows key removal. 2. ACCESSORY, allows the electrical accessories such as the radio to operate while the engine is not running. 3. ON, all electrical circuits operational. Warning lights illuminated. Key position when driving. 4. START, cranks the engine. Release the key once the engine starts. Preparing to start your vehicle Engine starting is controlled by the powertrain control system. This system meets all Canadian Interference-Causing Equipment standard requirements regulating the impulse electrical field strength of radio noise. When starting a fuel-injected engine, avoid pressing the accelerator before or during starting. Only use the accelerator when you have difficulty starting the engine. For more information on starting the vehicle, refer to Starting the engine in this chapter. Extended idling at high engine speeds can produce very high temperatures in the engine and exhaust system, creating the risk of fire or other damage. Do not park, idle, or drive your vehicle in dry grass or other dry ground cover. The emission system heats up the engine compartment and exhaust system, which can start a fire. Do not start your vehicle in a closed garage or in other enclosed areas. Exhaust fumes can be toxic. Always open the garage door before you start the engine. See Guarding against exhaust fumes in this chapter for more instructions. 253 2007 Expedition (exd) Owners Guide (post-2002-fmt) USA (fus) Driving If you smell exhaust fumes inside your vehicle, have your dealer inspect your vehicle immediately. Do not drive if you smell exhaust fumes. Important safety precautions A computer system controls the engine’s idle revolutions per minute (RPM). When the engine starts, the idle RPM runs higher than normal in order to warm the engine. If the engine idle speed does not slow down automatically, have the vehicle checked. Do not allow the vehicle to idle for more than 10 minutes at the higher engine RPM. Before starting the vehicle: 1. Make sure all vehicle occupants have buckled their safety belts. For more information on safety belts and their proper usage, refer to the Seating and Safety Restraints chapter. 2. Make sure the headlamps and vehicle accessories are off. 3. Make sure the gearshift is in P (Park). 254 2007 Expedition (exd) Owners Guide (post-2002-fmt) USA (fus) 4. Make sure the parking brake is set. Driving 5. Turn the key to 3 (ON) without turning the key to 4 (START). Some warning lights will briefly illuminate. See Warning lights and chimes in the Instrument Cluster chapter for more information regarding the warning lights. Starting the engine Note: Whenever you start your vehicle, release the key once the engine starts. 1. Turn the key to 4 (START) without pressing the accelerator pedal and release once the engine starts. The key will return to 3 (ON). 2. When the engine starts, release the key. 255 2007 Expedition (exd) Owners Guide (post-2002-fmt) USA (fus) Driving 3. After idling for a few seconds, apply the brake, shift into gear and drive. Note: If the engine does not start within five seconds on the first try, turn the key to OFF, wait 10 seconds and try again. If the engine still fails to start, press the accelerator to the floor and try again; this will allow the engine to crank with the fuel shut off in case the engine is flooded with fuel. This vehicle has a computer assisted cranking system which assists in starting the engine. If the ignition key is turned to 4 (START) and then released when the engine begins cranking, the engine may continue cranking for up to 10 seconds or until the vehicle starts Guarding against exhaust fumes Carbon monoxide is present in exhaust fumes. Take precautions to avoid its dangerous effects. If you smell exhaust fumes inside your vehicle, have your dealer inspect your vehicle immediately. Do not drive if you smell exhaust fumes. Important ventilating information If the engine is idling while the vehicle is stopped for a long period of time, open the windows at least one inch (2.5 cm) or adjust the heating or air conditioning to bring in fresh air. ENGINE BLOCK HEATER (IF EQUIPPED) If your vehicle is factory equipped with an engine block heater, a rubber cap/plug assembly will be visibly attached to the grille on the front of the vehicle. For factory-equipped, this assembly is loose-shipped in-vehicle for authorized dealer installation. If not factory-equipped, the engine block heater can be purchased through authorized dealer accessories. Replacement rubber caps are available through the authorized dealer, 3L1Z-6E088-AA. Use of an engine block heater is strongly recommended if you live in a region where temperatures reach -10°F (-23°C) or below. For best 256 2007 Expedition (exd) Owners Guide (post-2002-fmt) USA (fus) Driving results, plug the heater in at least three hours before starting the vehicle (the heater can be plugged in the night before starting the vehicle). To plug the heater in, remove the cap from the plug and insert the plug into a 110 volt grounded outlet. Be sure to re-attach the cap onto the plug when the heater is not in use. To reduce the risk of electrical shock, do not use your heater with ungrounded electrical systems or two-pronged (cheater) adapters. BRAKES Your service brakes are self-adjusting. Refer to the scheduled maintenance information for scheduled maintenance. Occasional brake noise is normal and often does not indicate a performance concern with the vehicle’s brake system. In normal operation, automotive brake systems may emit occasional or intermittent squeal or groan noises when the brakes are applied. Such noises are usually heard during the first few brake applications in the morning; however, they may be heard at any time while braking and can be aggravated by environmental conditions such as cold, heat, moisture, road dust, salt or mud. If a “metal-to-metal,” “continuous grinding” or “continuous squeal” sound is present while braking, the brake linings may be worn-out and should be inspected by an authorized dealer. Refer to Brake system warning light in the Instrument Cluster chapter for information on the brake system warning light. BRAKE If you are driving down a long or steep hill, shift to a lower gear. Do not apply your brakes continuously, as they may overheat and become less effective. Anti-lock brake system (ABS) On ABS-equipped vehicles, a noise from the hydraulic pump motor and pulsation in the pedal may be observed during ABS braking events. Pedal pulsation coupled with noise while braking under panic conditions or on loose gravel, bumps, wet or snowy roads is normal and indicates proper functioning of the vehicle’s anti-lock brake system. The ABS performs a self-check after you start the engine and begin to drive away. A brief 257 2007 Expedition (exd) Owners Guide (post-2002-fmt) USA (fus) Driving mechanical noise may be heard during this test. This is normal. If a malfunction is found, the ABS warning light will come on. If the vehicle has continuous vibration or shudder in the steering wheel while braking, the vehicle should be inspected by an authorized dealer. The ABS operates by detecting the onset of wheel lockup during brake applications and compensates for this tendency. The wheels are prevented from locking even when the brakes are firmly applied. Using ABS • In an emergency or when maximum efficiency from the four-wheel ABS is required, apply continuous force on the brake. The four wheel ABS will be activated immediately, thus allowing you to retain steering control of your vehicle and, providing there is sufficient space, will enable you to avoid obstacles and bring the vehicle to a controlled stop. • The anti-lock system does not always reduce stopping distance. Always leave enough room between your vehicle and the vehicle in front of you to stop. • We recommend that you familiarize yourself with this braking technique. However, avoid taking any unnecessary risks. ABS ABS warning lamp The ABS warning lamp in the instrument cluster momentarily illuminates when the ignition is turned on. If the light does not illuminate momentarily at start up, remains on or continues to flash, the ABS needs to be serviced. With the ABS light on, the anti-lock brake system is disabled and normal braking is still effective unless the brake warning light also remains illuminated with parking brake released. (If your brake warning lamp illuminates, have your vehicle serviced immediately.) BRAKE 258 2007 Expedition (exd) Owners Guide (post-2002-fmt) USA (fus) Driving Parking brake Apply the parking brake whenever the vehicle is parked. To set the parking brake, press the parking brake pedal down until the pedal stops. The BRAKE warning lamp in the instrument cluster illuminates and remains illuminated (when the ignition is turned ON) until the parking brake is released. BRAKE If the parking brake is fully released, but the brake warning lamp remains illuminated, the brakes may not be working properly. See your authorized dealer. Always set the parking brake fully and make sure that the gearshift is securely latched in P (Park). The parking brake is not recommended to stop a moving vehicle. However, if the normal brakes fail, the parking brake can be used to stop your vehicle in an emergency. Since the parking brake applies only the rear brakes, the vehicle’s stopping distance will increase greatly and the handling of your vehicle will be adversely affected. 259 2007 Expedition (exd) Owners Guide (post-2002-fmt) USA (fus) Driving Pull the release lever to release the brake. Driving with the parking brake on will cause the brakes to wear out quickly and reduce fuel economy. ADVANCETRAC姞 WITH ROLL STABILITY CONTROL姟 (RSC) STABILITY ENHANCEMENT SYSTEM (IF EQUIPPED) The AdvanceTrac威 with RSC system provides stability enhancement features such as Roll Stability Control娂 (RSC), Electronic Stability Control (ESC) and Traction Control (TCS) for certain driving situations. The system includes an AdvanceTrac威 with RSC on/off button, and a “sliding car” icon in the instrument cluster. Some drivers may notice a slight movement of the brake pedal when the AdvanceTrac威 with RSC performs a system self-check. During AdvanceTrac威 with RSC operation you may experience the following: • A rumble, grunting, or grinding noise after startup and when driving • A slight deceleration of the vehicle • The AdvanceTrac威 with RSC indicator light will flash when the system • If your foot is on the brake pedal, you will feel a vibration in the • If the driving condition is severe and your foot is not on the brake, the brake pedal will move to apply higher brake forces. You may also hear a whoosh of air from under the instrument panel during this severe condition. is activated. pedal. off Traction Control Traction Control helps your vehicle maintain traction, when driving on slippery and/or hilly road surfaces, by detecting and controlling wheel spin. Excessive wheel spin is controlled by momentarily reducing engine power and/or applying the anti-lock brakes. Traction Control is a driver aid that helps your vehicle. 260 2007 Expedition (exd) Owners Guide (post-2002-fmt) USA (fus) Driving If your vehicle should become stuck in deep snow or mud, try switching the AdvanceTrac威 with RSC system off by pressing the AdvanceTrac威 with RSC button momentarily. This will allow your tires to “dig” for traction. If the AdvanceTrac威 with RSC system is activated excessively in a short period of time, the brake portion of the system will disable to allow the brakes to cool down. In this situation, Traction Control will use only engine power reduction to help control the wheels from over-spinning. When the brakes have cooled down, the system will again function normally. Anti-lock braking, RSC and ESC are not affected by this condition and will function normally during the cool-down period. If the vehicle is stuck in snow or mud or when driving in deep sand, switching off the AdvanceTrac with RSC system may be beneficial so the wheels are allowed to spin. If your vehicle seems to lose engine power while driving in deep sand or very deep snow, switching off the AdvanceTrac with RSC stability enhancement feature will restore full engine power and will enhance momentum through the obstacle. During Traction Control events the “sliding car” icon in the instrument cluster will flash momentarily. Electronic Stability Control (ESC) The Electronic Stability Control (ESC) with RSC system may enhance your vehicle’s stability during adverse maneuvers. The AdvanceTrac威 with RSC system helps the driver maintain steering control. AdvanceTrac威 with RSC will attempt to correct the vehicle motion by applying brake force at individual tires and, if necessary, by reducing engine power. During Electronic Stability Control events the “sliding car” icon in the instrument cluster will flash momentarily. Driving maneuvers which may activate AdvanceTrac威 with RSC system include: • Taking a turn too fast. • Maneuvering quickly to avoid an accident, pedestrian or obstacle. • Driving over a patch of ice. • Changing lanes on a snow-rutted road. • Entering a snow-free road from a snow-covered side street, or vice • Entering a paved road from a gravel road, or vice versa. versa. 261 2007 Expedition (exd) Owners Guide (post-2002-fmt) USA (fus) Driving • Driving on slick surfaces. • Cornering while towing a heavily loaded trailer (refer to Trailer towing in the Tires, Wheels and Loading chapter.) Roll Stability Control娂 (RSC) The RSC system works in conjunction with the AdvanceTrac威 system to help maintain roll stability of the vehicle during aggressive maneuvers by applying brake force to one or more wheels. During Roll Stability Control娂 (RSC) events the “sliding car” icon in the instrument cluster will flash momentarily. Driving conditions that may activate AdvanceTrac威 with RSC include: • Emergency lane-change • Taking a turn too fast • Quick maneuvering to avoid an accident, pedestrian or obstacle AdvanceTrac威 with RSC button and icon functionality The AdvanceTrac威 with RSC system automatically turns on each time the engine is started, even if it was turned off when the engine was last shut down. All functions of the AdvanceTrac威 with RSC (RSC, ESC, Engine Traction Control, and Brake Traction Control) will be activated at start up. When the system is left active, the “sliding car” icon in the reconfigurable telltale (RTT) location in the message center will flash only when any of the components of the system are affecting the vehicle’s performance, otherwise the light will remain off. Consequently, the “sliding car” icon will not be illuminated during most of your normal driving. The AdvanceTrac威 with RSC button, located on the center stack of the instrument panel, allows the driver to control certain features of the AdvanceTrac威 with RSC system below 25 mph (40 km/h). If the vehicle is below 25 mph (40 km/h), momentarily pressing the AdvanceTrac威 with RSC button will disable RSC, ESC and Engine Traction Control and steadily illuminate the “sliding car” icon. Pressing and holding the AdvanceTrac威 with RSC button for more than five seconds will further disable the brake portion of the Traction Control feature and the “sliding car” icon will flash momentarily and then illuminate steady. If the vehicle is above 25 mph (40 km/h), momentarily pressing the AdvanceTrac威 with RSC button will steadily illuminate the “sliding car” 262 2007 Expedition (exd) Owners Guide (post-2002-fmt) USA (fus) Driving icon, however, the AdvanceTrac威 with RSC system will remain enabled until the vehicle speed drops below 25 mph. If the vehicle speed decreases below 25 mph (40 km/h), the system will become deactivated, but if the vehicle speed subsequently increases to above 25 mph (40 km/h), the system will again become active. In general, the system will be active at all times the vehicle speed is above 25 mph (40 km/h). When in R (Reverse) or in 4L (4x4 Low), ABS and the Traction Control feature will continue to function, however ESC and RSC are disabled. All these conditions are normal during AdvanceTrac威 with RSC operation. Refer to the following table. AdvanceTrac威 with RSC Features “Sliding car” icon RSC ESC Engine Traction Control Brake Traction Control Off Enabled Enabled Enabled Enabled Illuminated solid Disabled below 25 mph Disabled below 25 mph Disabled below 25 mph (40 km/h) (40 km/h) (40 km/h) Enabled Flashes then illuminated Disabled below 25 mph Disabled below 25 mph Disabled below 25 mph Disabled below 25 mph solid (40 km/h) (40 km/h) (40 km/h) (40 km/h) Button functions Default at start-up Button pressed momentarily Button pressed and held more than five seconds Do not alter or modify your vehicle’s suspension or steering; the resulting changes to the vehicle’s handling can adversely affect the AdvanceTrac威 with RSC system. Also, do not install a stereo loudspeaker near the front center console or tunnel or under either front seat as the vibrations can adversely affect the AdvanceTrac威 with RSC sensors located in this area. 263 2007 Expedition (exd) Owners Guide (post-2002-fmt) USA (fus) Driving Aggressive driving in any road conditions can cause you to lose control of your vehicle increasing the risk of severe personal injury or property damage. The occurrence of a AdvanceTrac威 with RSC event is an indication that at least some of the tires have exceeded their ability to grip the road; this may lead to an increased risk of loss of vehicle control, vehicle rollover, personal injury and death. If you experience a severe road event, SLOW DOWN. If a failure is detected in the AdvanceTrac威 with RSC system, the “sliding car” icon illuminates solid in the instrument cluster message center and will stay on. If the “sliding car” icon in the instrument cluster message center remains on solid while the engine is running, without the AdvanceTrac威 with RSC button having been pushed, have the system serviced by an authorized dealer immediately. for more than a few seconds when the engine is running. STEERING Your vehicle is equipped with power steering. Power steering uses energy from the engine to decrease the driver’s effort in steering the vehicle. To help prevent damage to the power steering pump: • Never hold the steering wheel to the extreme right or the extreme left • Do not operate the vehicle with the power steering pump fluid level • Some noise is normal during operation. If the noise is excessive, check for low power steering pump fluid level before seeking service by your authorized dealer. • Heavy or uneven steering efforts may be caused by low power steering pump fluid level. Check for low power steering pump fluid level before seeking service by your authorized dealer. • Do not fill the power steering pump reservoir above the MAX mark on below the MIN mark on the reservoir. the reservoir, as this may result in leaks from the reservoir. If the power steering system breaks down (or if the engine is turned off), you can steer the vehicle manually, but it takes more effort. If the steering wanders or pulls, check for: • Underinflated tire(s) on any wheel(s) • Uneven vehicle loading • High crown in center of road 264 2007 Expedition (exd) Owners Guide (post-2002-fmt) USA (fus) Driving • High crosswinds • Wheels out of alignment • Loose or worn suspension components Variable assist steering Your vehicle is equipped with variable assist power steering. At low engine RPM, steering assist will adjust to reduce efforts and improve low speed maneuverability. At high engine RPM, the assist will adjust to improve steering feel at high speeds. If the amount of effort required to steer your vehicle changes while driving at a constant engine RPM, have the power steering system checked by your authorized dealer. AIR SUSPENSION SYSTEM (IF EQUIPPED) The air suspension system is designed to improve ride, handling and general vehicle performance during: • Certain road conditions • Steering maneuvers • Braking • Acceleration This system keeps the rear of your vehicle at a constant level by automatically adding air or releasing air from the springs. If you exceed the load limit, the rear air suspension may not operate. The air suspension system will stay active for 40 minutes after the ignition is turned off to accommodate any load changes. (The air compressor may run when the vehicle is off; this is normal.) The air suspension system can be enabled or disabled through the message center. Refer to Message center in the Driver Controls chapter. If the system is off, the rear air suspension will not operate and will not raise (pump) or lower (vent) while the vehicle is not moving. However, if the system determines that the vehicle is low or high and needs to make a height adjustment while driving at speeds above 15 mph (24 km/h), the system will pump or vent as required. Normal vehicle operation does not require any action by the driver. On vehicles equipped with air suspension, turn the air suspension and the ignition switch off prior to jacking, hoisting or towing your vehicle. 265 2007 Expedition (exd) Owners Guide (post-2002-fmt) USA (fus) Driving LIMITED-SLIP AXLE (IF EQUIPPED) This axle provides added traction on slippery surfaces, particularly when one wheel is on a poor traction surface. Under normal conditions, the limited slip axle functions like a standard rear axle. Extended use of other than the manufacturer’s specified size tires on a limited slip rear axle could result in a permanent reduction in effectiveness. This loss of effectiveness does not affect normal driving and should not be noticeable to the driver. PREPARING TO DRIVE Utility vehicles have a significantly higher rollover rate than other types of vehicles. In a rollover crash, an unbelted person is significantly more likely to die than a person wearing a seat belt. Utility vehicles and trucks have larger tires and increased ground clearance, giving the vehicle a higher center of gravity than a passenger car. Vehicles with a higher center of gravity such as utility vehicles and trucks handle differently than vehicles with a lower center of gravity. Utility vehicles and trucks are not designed for cornering at speeds as high as passenger cars any more than low-slung sports cars are designed to perform satisfactorily under off-road conditions. Avoid sharp turns, excessive speed or abrupt maneuvers in these vehicles. Failure to drive cautiously could result in an increased risk of loss of vehicle control, vehicle rollover, personal injury and death. Loaded vehicles, with a higher center of gravity, may handle differently than unloaded vehicles. Do not overload your vehicle and use extra precautions, such as driving at slower speeds, avoiding abrupt steering changes and allowing for increased stopping distance, when driving a heavily loaded vehicle. Over loading or loading the vehicle improperly can deteriorate handling capability and contribute to loss of vehicle control and vehicle rollover. AUTOMATIC TRANSMISSION OPERATION Brake-shift interlock – column-shift transmission This vehicle is equipped with a park/brake-shift interlock feature that prevents the gearshift lever from being moved from P (Park) when the ignition is in the ON position unless brake pedal is depressed. 266 2007 Expedition (exd) Owners Guide (post-2002-fmt) USA (fus) Driving If you cannot move the gearshift lever out of P (Park) with ignition in the ON position and the brake pedal depressed, or when the ignition is in the OFF position, it is possible that a fuse has blown or the vehicle’s brakelamps are not operating properly. Refer to Fuses and relays in the Roadside Emergencies chapter. If the fuse is not blown, perform the following procedure: 1. Apply the parking brake. 2. Turn the key to the OFF position. 3. Remove the access plug on top of the steering column. 4.

Turn the ignition to the LOCK position and remove the key whenever you leave your vehicle. If the parking brake is fully released, but the brake warning lamp remains illuminated, the brakes may not be working properly. See your authorized dealer. Driving with a 6–speed automatic transmission This vehicle is equipped with an Adaptive Transmission Shift Strategy. The Adaptive Transmission Shift Strategy offers the optimal transmission operation and shift quality. When the engine is turned off, the shift data which includes the adaptive information will be stored automatically in the Transmission Control Module (TCM). If the battery is disconnected for any reason, the stored information from the last time the key was turned to OFF will be read. This way, no information will be lost with any battery removal or battery disconnect. P (Park) This position locks the transmission and prevents the rear wheels from turning. To put your vehicle in gear: • Depress the brake pedal • Start the engine • Move the gearshift lever into the desired gear. If your vehicle is equipped with a floor-shift transmission, press the gearshift lever release button (on the front of the lever) while shifting into the desired gear. 269 2007 Expedition (exd) Owners Guide (post-2002-fmt) USA (fus) Driving To put your vehicle in P (Park): • Come to a complete stop • Move the gearshift lever and securely latch it in P (Park) Always set the parking brake fully and make sure the gearshift is latched in P (Park). Turn the ignition to the LOCK position and remove the key whenever you leave your vehicle. R (Reverse) With the gearshift lever in R (Reverse), the vehicle will move backward. Always come to a complete stop before shifting into and out of R (Reverse). N (Neutral) With the gearshift lever in N (Neutral), the vehicle can be started and is free to roll. Hold the brake pedal down while in this position. D (Drive) with Overdrive The normal driving position for the best fuel economy.
