Position the child safety seat on the seat cushion. 2. Route the child safety seat tether strap over the back of the seat. 3. Locate the correct anchor for the selected seating position. 4. You may need to pull the seatback forward to access the tether anchors. Make sure the seat is locked in the upright position before installing the child seat. Refer to the Rear folding seat system with load floor section in this chapter for information on how to operate the rear seats. 5. Clip the tether strap to the anchor as shown. • Front seats (Regular Cab) • Front seat (SuperCab) 130 2007 F-250/350/450/550 (f23) Owners Guide (post-2002-fmt) USA (fus) • Rear seats (Crew Cab) Seating and Safety Restraints If the tether strap is clipped incorrectly, the child safety seat may not be retained properly in the event of a collision. 6. Refer to the Installing child safety seats in combination lap and shoulder belt seating positions section of this chapter for further instructions to secure the child safety seat. 7. Tighten the child safety seat tether strap according to the manufacturer’s instructions. If the safety seat is not anchored properly, the risk of a child being injured in a collision greatly increases. Tether strap attachment (rear SuperCab only) There are three loops of webbing just above the back of the rear seat (along the bottom edge of the rear window) in the SuperCab. These loops are to be used as both routing loops and anchor loops for up to three child safety seat tether straps. Many tether straps cannot be tightened if the tether strap is hooked to the loop directly behind the child seat. To provide a tight tether strap: 131 2007 F-250/350/450/550 (f23) Owners Guide (post-2002-fmt) USA (fus) Seating and Safety Restraints 1. Route the tether strap through the loop directly behind the child seat. 2. Attach the strap hook onto the loop behind an adjacent seating position. 3. Install the child safety seat tightly using the vehicle belts. Follow the instructions in this chapter. 4. Tighten the tether strap according to the child seat manufacturer’s instructions. A single loop can be used to route and anchor more than one child seat. For example, the center loop can be used as a routing loop for a child safety seat in the center rear seat and as an anchoring loop for child seats installed in the outboard rear seats. 132 2007 F-250/350/450/550 (f23) Owners Guide (post-2002-fmt) USA (fus) Tires, Wheels and Loading NOTICE TO UTILITY VEHICLE AND TRUCK OWNERS Utility vehicles and trucks handle differently than passenger cars in the various driving conditions that are encountered on streets, highways and off-road. 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. Utility vehicles have a significantly higher rollover rate than other types of vehicles. To reduce the risk of serious injury or death from a rollover or other crash you must: • Avoid sharp turns and abrupt maneuvers; • Drive at safe speeds for the conditions; • Keep tires properly inflated; • Never overload or improperly load your vehicle; and • Make sure every passenger is properly restrained. In a rollover crash, an unbelted person is significantly more likely to die than a person wearing a seat belt. All occupants must wear safety belts and children/infants must use appropriate restraints to minimize the risk of injury or ejection. Study your Owner’s Guide and any supplements for specific information about equipment features, instructions for safe driving and additional precautions to reduce the risk of an accident or serious injury. VEHICLE CHARACTERISTICS 4WD and AWD Systems (if equipped) A vehicle equipped with AWD or 4WD (when you select the 4WD mode) has the ability to use all four wheels to power itself. This increases traction which may enable you to safely drive over terrain and road conditions that a conventional two-wheel drive vehicle cannot. 133 2007 F-250/350/450/550 (f23) Owners Guide (post-2002-fmt) USA (fus) Tires, Wheels and Loading Power is supplied to all four wheels through a transfer case or power transfer unit. 4WD vehicles allow you to select different drive modes as necessary. Information on shifting procedures and maintenance can be found in your Owner’s Guide. You should become thoroughly familiar with this information before you operate your vehicle. On some 4WD models, the initial shift from two-wheel drive to 4WD while the vehicle is moving can cause a momentary clunk and ratcheting sound. These sounds are normal as the front drivetrain comes up to speed and is not cause for concern. Do not become overconfident in the ability of 4WD and AWD vehicles. Although a 4WD or AWD vehicle may accelerate better than two-wheel drive vehicle in low traction situations, it won’t stop any faster than two-wheel drive vehicles. Always drive at a safe speed. How your vehicle differs from other vehicles SUV and trucks can differ from some other vehicles in a few noticeable ways. Your vehicle may be: • Higher – to allow higher load carrying capacity and to allow it to travel over rough terrain without getting hung up or damaging underbody components. • Shorter – to give it the capability to approach inclines and drive over the crest of a hill without getting hung up or damaging underbody components. All other things held equal, a shorter wheelbase may make your vehicle quicker to respond to steering inputs than a vehicle with a longer wheelbase. 134 2007 F-250/350/450/550 (f23) Owners Guide (post-2002-fmt) USA (fus) Tires, Wheels and Loading • Narrower — to provide greater maneuverability in tight spaces, particularly in off-road use. As a result of the above dimensional differences, SUV’s and trucks often will have a higher center of gravity and a greater difference in center of gravity between the loaded and unloaded condition. These differences that make your vehicle so versatile also make it handle differently than an ordinary passenger car. INFORMATION ABOUT UNIFORM TIRE QUALITY GRADING New vehicles are fitted with tires that have a rating on them called Tire Quality Grades. The Quality grades can be found where applicable on the tire sidewall between tread shoulder and maximum section width. For example: • Treadwear 200 Traction AA Temperature A These Tire Quality Grades are determined by standards that the United States Department of Transportation has set. Tire Quality Grades apply to new pneumatic tires for use on passenger cars. They do not apply to deep tread, winter-type snow tires, space-saver or temporary use spare tires, tires with nominal rim diameters of 10 to 12 inches or limited production tires as defined in Title 49 Code of Federal Regulations Part 575.104(c)(2). U.S. Department of Transportation-Tire quality grades: The U.S. Department of Transportation requires Ford to give you the following information about tire grades exactly as the government has written it. Treadwear The treadwear grade is a comparative rating based on the wear rate of the tire when tested under controlled conditions on a specified 135 2007 F-250/350/450/550 (f23) Owners Guide (post-2002-fmt) USA (fus) Tires, Wheels and Loading 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. The relative performance of tires depends upon the actual conditions of their use, however, and may depart significantly from the norm due to variations in driving habits, service practices, and differences in road characteristics and climate. Traction AA A B C 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. The traction grade assigned to this tire is based on straight-ahead braking traction tests, and does not include acceleration, cornering, hydroplaning or peak traction characteristics. Temperature A B C The temperature grades are A (the highest), B and C, representing the tire’s resistance to the generation of heat and its ability to dissipate heat when tested under controlled conditions on a specified indoor laboratory test wheel. Sustained high temperature can cause the material of the tire to degenerate and reduce tire life, and excessive temperature can lead to sudden tire failure. The grade C corresponds to a level of performance which all passenger car tires must meet under the Federal Motor Vehicle Safety Standard No. 109. Grades B and A represent higher levels of performance on the laboratory test wheel than the minimum required by law. The temperature grade for this tire is established for a tire that is properly inflated and not overloaded. Excessive speed, underinflation, or excessive loading, either separately or in combination, can cause heat buildup and possible tire failure. TIRES Tires are designed to give many thousands of miles of service, but they must be maintained in order to get the maximum benefit from them. 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. 136 2007 F-250/350/450/550 (f23) 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 Tire Label or Safety Compliance Certification 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. 137 2007 F-250/350/450/550 (f23) 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 the Tire Label. 138 2007 F-250/350/450/550 (f23) 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 with the tire gauge. 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 60 psi (4.15 bars). For Dissimilar spare tires and Full-size matching spare tires (see the Dissimilar Spare Tire/Wheel Information and Full-size Matching Spare Tire/Wheel Information sections for descriptions): Store and maintain at the higher of the front and rear inflation pressure as shown on the or Safety Compliance Certification Label or 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. 139 2007 F-250/350/450/550 (f23) Owners Guide (post-2002-fmt) USA (fus) Tires, Wheels and Loading Tire inflation information All tires with Steel Carcass Plies (if equipped): This type of tire utilizes steel cords in the sidewalls. As such, they cannot be treated like normal light truck tires. Tire service, including adjusting the air pressure, must be performed by personnel trained, supervised and equipped according to Federal Occupational Safety and Health Administration (OSHA) regulations. For example, during any procedure involving tire inflation, the technician or individual must utilize a remote inflation device, and ensure that all persons are clear of the trajectory area. WARNING An inflated tire and rim can be very dangerous if improperly used, serviced or maintained. To avoid serious injury, never attempt to re-inflate a tire which has been run flat or seriously under-inflated without first removing the tire from the wheel assembly for inspection. Do not attempt to add air to tires or replace tires or wheels without first taking precautions to protect persons and property. 140 2007 F-250/350/450/550 (f23) Owners Guide (post-2002-fmt) USA (fus) Tires, Wheels and Loading Stay out of the trajectory (1) as indicated in the illustration. 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 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. 141 2007 F-250/350/450/550 (f23) Owners Guide (post-2002-fmt) USA (fus) Tires, Wheels and Loading 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 6 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 6 years due to aging even if it has not been used. 142 2007 F-250/350/450/550 (f23) Owners Guide (post-2002-fmt) USA (fus) Tires, Wheels and Loading U.S. DOT Tire Identification Number (TIN) 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. 143 2007 F-250/350/450/550 (f23) 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 you have the correct tire and wheel size 2. Lubricate the tire bead and wheel bead 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. 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 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. Never spin the tires in excess of the 35 mph (55 km/h) point indicated on the speedometer. 144 2007 F-250/350/450/550 (f23) Owners Guide (post-2002-fmt) USA (fus) Tires, Wheels and Loading 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 your 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 your 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). 145 2007 F-250/350/450/550 (f23) Owners Guide (post-2002-fmt) USA (fus) Tires, Wheels and Loading • Rear Wheel Drive (RWD) vehicles/Four Wheel Drive (4WD) (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 your 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. 146 2007 F-250/350/450/550 (f23) Owners Guide (post-2002-fmt) USA (fus) Tires, Wheels and Loading • DRW – Six tire rotation If your vehicle is equipped with dual rear wheels it is recommended that the front and rear tires (in pairs) be rotated only side to side. We do not recommend splitting up the dual rear wheels. Rotate them side to side as a set/pair. After tire rotation, inflation pressures must be adjusted for the tires new positions in accordance with vehicle requirements. Sometimes irregular tire wear can be corrected by rotating the tires. Note: If your tires show uneven wear ask your 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 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. 147 2007 F-250/350/450/550 (f23) 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. 148 2007 F-250/350/450/550 (f23) 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 Tire Label or 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. 149 2007 F-250/350/450/550 (f23) 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 either the Tire Label or Safety Compliance Certification 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. 150 2007 F-250/350/450/550 (f23) 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.

Note: Do not use snow chains on front tires of vehicles with 20” wheels and tires. 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 SAE Class S chains. • Install chains securely, verifying that the chains do not touch any • Drive cautiously. If you hear the chains rub or bang against your 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. • 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. tire chains on dry roads. 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 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. 153 2007 F-250/350/450/550 (f23) Owners Guide (post-2002-fmt) USA (fus) Tires, Wheels and Loading 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 (vehicles exported outside the U.S. and Canada may not have a Tire Label) on the B-Pillar or the edge of the driver’s door. 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. 154 2007 F-250/350/450/550 (f23) 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. 155 2007 F-250/350/450/550 (f23) 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. Exceeding the Safety Compliance Certification Label axle 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. 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. 156 2007 F-250/350/450/550 (f23) Owners Guide (post-2002-fmt) USA (fus) Tires, Wheels and Loading 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. 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 vehicles’ 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. 157 2007 F-250/350/450/550 (f23) Owners Guide (post-2002-fmt) USA (fus) Tires, Wheels and Loading 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 originals because they may lower the vehicle’s GVWR and GAWR limitations. Replacement tires with a higher limit than the originals do not increase the GVWR and GAWR limitations. 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. (1,400–750 (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. 158 2007 F-250/350/450/550 (f23) Owners Guide (post-2002-fmt) USA (fus) Tires, Wheels and Loading 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 1,400 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: 1,400 – (5 x 220) – (5 x 30) = 1,400 – 1,100 – 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 1,400 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 transport the cement to your home? If you and your friend each weigh 220 lb. (99 kg), the calculation would be: 1,400 – (2 x 220) – (12 x 100) = 1,400 – 440 – 1,200 = – 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: 1,400 – (2 x 220) – (9 x 100) = 1,400 – 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 Tire Label or 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. 159 2007 F-250/350/450/550 (f23) Owners Guide (post-2002-fmt) USA (fus) Tires, Wheels and Loading Loaded vehicles 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 can 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 Note: The trailer towing charts in this section apply to vehicles equipped with gasoline engines; for vehicles equipped with diesel engines, refer to your 6.0 Liter Power Stroke Direct Injection Turbo Diesel Owner’s Guide Supplement . Your vehicle may tow a Conventional/Class IV trailer or fifth wheel trailer provided the maximum trailer weight is less than or equal to the maximum trailer weight listed for your engine and rear axle ratio on the following charts. To calculate your maximum trailer weight: For pickup trucks: Take curb weight, hitch hardware and the driver’s weight, then subtract them from the GCWR listed for your vehicle series, engine, transmission and drive axle ratio (refer to the chart/table in the following text). This calculation will give you the maximum trailer weight possible for your vehicle. For chassis cabs and pickup trucks with aftermarket equipment: Weigh your vehicle at a certified scale and subtract this actual curb weight, hitch hardware, and the driver’s weight from the GCWR listed for your vehicle series, engine, transmission and drive axle ratio (refer to the chart/table in the following text). This calculation will give you the maximum trailer weight possible for your vehicle. The weight of all additional cargo and passengers must be subtracted from the maximum trailer weight calculated above. Further trailer/hitch restrictions and limitations exist depending on the type of trailer and hitch used. These additional maximum trailer weight and tongue load limitations are listed in the chart/table that follows the listing of GCWRs. Towing a trailer places an additional load on your vehicle’s engine, transmission, axle, brakes, tires and suspension. Inspect these components carefully prior to and after any towing operation. Refer to Transmission fluid temperature gauge in the Instrument Cluster chapter for the transmission fluid temperature information. 160 2007 F-250/350/450/550 (f23) Owners Guide (post-2002-fmt) USA (fus) Tires, Wheels and Loading Note: Do not exceed the GCWR listed for your vehicle on the following chart/table, or the GVWR, GAWR or tire ratings specified on the Tire Label or Safety Compliance Certification Label. Towing trailers beyond the maximum recommended trailer weight which exceeds the limit of the vehicle’s GCWR, GVWR, GAWR or tire ratings could result in engine damage, transmission damage, structural damage, loss of vehicle control, vehicle rollover and personal injury.

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% for conventional towing or 15%-25% fifth-wheel towing of the total weight of the trailer is on the tongue. 161 2007 F-250/350/450/550 (f23) 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.

Park the unloaded vehicle on a level surface. With the ignition on and all doors closed, allow the vehicle to stand for several minutes so that it can level. 2. Measure the height of a reference point on the front and rear bumpers at the center of the vehicle. 3. Attach the trailer to the vehicle and adjust the hitch equalizers so that the front bumper height is within 1⁄2” (13 mm) of the reference point. After proper adjustment, the rear bumper should be no higher than in Step 2. 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. If you own a trailer with a hydraulic brake system, do not connect the trailer’s hydraulic brake system directly to your vehicle’s brake system. The vehicle’s brake system is only designed to carry the appropriate amount of brake fluid for the vehicle alone. Connecting a hydraulic trailer braking system could adversely affect your vehicle’s braking performance. The braking system of the tow vehicle is rated for operation at the GVWR not GCWR. 163 2007 F-250/350/450/550 (f23) Owners Guide (post-2002-fmt) USA (fus) Tires, Wheels and Loading Integrated trailer brake controller (if equipped) Your vehicle may be equipped with a fully integrated electronic Trailer Brake Controller (TBC). When used properly, the TBC helps ensure smooth and effective trailer braking by powering the trailer’s electric brakes with a proportional output based on the towing vehicle’s brake pressure. The Ford TBC has only been verified to be compatible with trailers having electric-actuated drum brakes (one to four axles) and not hydraulic surge or electric-over-hydraulic types. It is the responsibility of the customer to ensure that the trailer brakes are adjusted appropriately, functioning normally and all electric connections are properly made. The TBC user interface consists of the following: 1. +/- (GAIN adjustment buttons): Pressing these buttons will adjust the TBC’s power output to the trailer brakes (in 0.5 increments). The GAIN setting can be increased to a maximum of 10.0 or decreased to a minimum of 0 (no trailer braking). Pressing and holding a button will raise or lower the setting continuously. 2. Trailer connection indicator: This lamp indicates trailer electrical connection status. • When a successful trailer connection is detected, the indicator will be • If the electrical connection is lost, the indicator will flash red. If the green. connection is lost while the vehicle is stationary, the indicator will turn off after 30 seconds. If the connection is lost while the vehicle is moving, the indicator will flash until the ignition is turned off, then on again. • If no electrical connection is detected after the ignition is turned on, pressing a GAIN adjustment button will display the GAIN setting. Sliding the manual control will display the GAIN setting, OUTPUT bar graph and light the trailer indicator red. 164 2007 F-250/350/450/550 (f23) Owners Guide (post-2002-fmt) USA (fus) Tires, Wheels and Loading 3. GAIN setting display: Shows the current GAIN setting. This will illuminate when a trailer is connected, flash if the trailer becomes disconnected, or remain off if no trailer is connected. 4. OUTPUT bar graph: When the vehicle’s brake pedal is pushed, or when the manual control is activated, green bar indicators will illuminate to indicate the amount of power going to the trailer brakes relative to the brake pedal or manual control input. 5. Manual control lever: Slide the control lever to the left to activate power to the trailer’s electric brakes independent of the tow vehicle’s brakes (see the following Procedure for adjusting GAIN section for instructions on proper use of this feature). If the manual control is activated while the brake is also applied, the greater of the two inputs determines the power sent to the trailer brakes. • Stop Lamps: Activating the TBC manual control lever will illuminate both the trailer brake lamps and the tow vehicle brake lamps (presuming proper trailer electrical connection). Pressing the vehicle brake pedal will also illuminate both trailer and vehicle brake lamps. GAIN The GAIN setting is used to set the TBC for the specific towing condition and should be changed as towing conditions change. Changes to towing conditions include trailer load, vehicle load, road conditions and weather. The GAIN should be set to provide the maximum trailer braking assistance while ensuring the trailer wheels do not lock when braking. Locked trailer wheels may lead to trailer instability. Procedure for adjusting GAIN: Note: This should only be performed in a traffic free environment at speeds of approximately 20 – 25 mph (30 – 40 km/h). 1. Make sure the trailer brakes are in good working condition, functioning normally, and properly adjusted. See your trailer dealer if necessary. 2. Hook-up the trailer and make the electrical connections according to the trailer manufacturer’s instructions. 3. When a trailer with electric brakes is plugged in, the trailer connection indicator will illuminate green on the TBC and the GAIN setting display will illuminate. 4. Use the GAIN adjustment (+/-) buttons to increase or decrease the GAIN setting to the desired starting point. (A GAIN setting of 6.0 is a good starting point for heavier loads.) 165 2007 F-250/350/450/550 (f23) Owners Guide (post-2002-fmt) USA (fus) Tires, Wheels and Loading 5. In a traffic-free environment, tow the trailer on a dry, level surface at a speed of 20 – 25 mph (30 – 40 km/h) and squeeze the manual control lever completely. 6. If the trailer wheels lock-up (indicated by squealing tires), reduce the GAIN setting; if the trailer wheels turn freely, increase the GAIN setting. Repeat Steps 5 and 6 until the GAIN setting is at a point just below trailer wheel lock-up. If towing a heavier trailer, trailer wheel lockup may not be attainable even with the maximum GAIN setting of 10. Explanation of instrument cluster messages: The TBC interacts with the instrument cluster message center. These messages, accompanied by a single chime, will be displayed when the TBC determines a malfunction in the trailer connection, TBC system, or in the trailer. These messages are listed below: TRAILER DISCONNECTED (if equipped with message center) or CHECK TRAILER (if equipped with mini message center): This message is displayed when a trailer connection was determined and then a disconnection, either intentionally or unintentionally, has been sensed during a given ignition cycle. It is also displayed if a trailer fault occurs causing the trailer to appear disconnected. This message is also displayed during manual activation without a trailer connected. TBC FAULT: This message is displayed in response to faults sensed by the TBC. In the event this message is seen, please take your vehicle to an authorized dealer for diagnosis and repair. The TBC may still function, but performance may be degraded. TRAILER FAULT: The TBC is capable of determining certain faults in the vehicle wiring and trailer wiring/brake system. These faults do not mean there is anything wrong with the TBC. This message is displayed when one of the following faults has occurred: • Short circuit on the electric brake output wire: If the TRAILER FAULT message is displayed with no trailer connected, the problem is with the vehicle wiring from the TBC to the 7–pin connector in the bumper. If the message is only displayed with a trailer connected, the problem is related to the trailer wiring; consult your trailer dealer for assistance. This can be a short to ground (i.e., chaffed wire) or a short to voltage (i.e., pulled pin on trailer emergency break-away battery). • Trailer brake overload: The trailer brakes are drawing too much current; consult your trailer dealer for assistance. Note: Your TBC can be diagnosed by your authorized dealer to determine exactly which trailer fault has occurred; however, if the fault is with the trailer this diagnosis is not covered under your Ford warranty. 166 2007 F-250/350/450/550 (f23) Owners Guide (post-2002-fmt) USA (fus) Tires, Wheels and Loading Points to Remember: • Remember to adjust gain setting before using the TBC for the first • Readjust GAIN setting on the TBC (according to procedure above) time. whenever road, weather and trailer or vehicle loading conditions change from those that existed when the gain was initially set. • The sliding lever on the TBC should be used only for manual activation of trailer brakes to assist with proper adjustment of the GAIN. Misuse, such as application during trailer sway, could cause instability of trailer and/or tow vehicle. • Avoid towing in adverse weather conditions. The TBC does not provide anti-lock control of the trailer wheels. Trailer wheels can lock-up on slippery surfaces, resulting in reduced stability of trailer and tow vehicle. • The TBC interacts with the brake system of the vehicle, including ABS, in order to reduce the likelihood of trailer wheel lockup. Therefore, if these systems are not functioning properly the TBC may not function at full performance. • When the vehicle is turned off, the TBC Output is disabled and the display is shut down. Reactivation of the ignition from 3 (OFF) to 4 (ON) will awaken the TBC module. • The TBC is only a factory or dealer installed item. Ford is not responsible for warranty or performance of the TBC due to misuse or customer installation. • Do not attempt removal of the TBC without consulting the Workshop Manual. Damage to the unit may result. 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. Using a step bumper (if equipped) The rear bumper is equipped with an integral hitch and only requires a ball with a one inch (25.4 mm) shank diameter. The bumper has a 5,000 lb. (2,270 kg) trailer weight and 500 lb. (227 kg) tongue weight capacity. If it is necessary to relocate the trailer hitch ball position, a frame-mounted trailer hitch must be installed. 167 2007 F-250/350/450/550 (f23) Owners Guide (post-2002-fmt) USA (fus) Tires, Wheels and Loading Driving while you tow When towing a trailer: • Do not drive faster than 70 mph (112 km/h) during the first 500 miles (800 km) of trailer towing 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 transmission shifting, activate the Tow/Haul feature. This will also assist in transmission cooling. (For additional information, refer to the Understanding the shift positions of the 5–speed automatic transmission section in the Driving chapter. • Anticipate stops and brake gradually. • Do not exceed the GCWR rating or transmission damage may occur. • Your vehicle may be equipped with a temporary or conventional spare tire.

Exceeding these limits may allow water to enter critical vehicle components, adversely affecting driveability, emissions and reliability. Replace front and rear axle lubricants any time the axles have been submerged in water. Axle lubricant quantities are not to be checked unless a leak is suspected. RECREATIONAL TOWING This applies to all 4x2 trucks with rear wheel drive capability. An example of recreational towing is towing your vehicle behind a motorhome. The following recreational towing guidelines are designed to ensure that your transmission is not damaged. • Place the transmission in N (Neutral). • Maximum speed is 35 mph (56 km/h). • Maximum distance is 50 miles (80 km). If a distance of 50 miles (80 km) or a speed of 35 mph (56 km/h) must be exceeded, you must disconnect the driveshaft. Ford recommends the driveshaft be removed/installed only by a qualified technician. See your local 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. 170 2007 F-250/350/450/550 (f23) Owners Guide (post-2002-fmt) USA (fus) Tires, Wheels and Loading 4x4 with manual shift transfer case: • Place the transfer case in N (Neutral). • Front hub locks are in the FREE position. 4x4 electronic shift transfer case vehicles with automatic transmissions: Regarding recreational towing or having your vehicle towed, 4x4 vehicles with electronic shift on the fly cannot be towed with any wheels on the ground unless the rear driveshaft is removed and the front hub locks are in free mode (with the exception of moving it as a disabled vehicle off the road out of traffic). The hub locks can be set to free mode at any time by turning them from AUTO to LOCK and back to AUTO at least two times. Always make sure that both hub locks are set to the same position. 171 2007 F-250/350/450/550 (f23) Owners Guide (post-2002-fmt) USA (fus) Driving STARTING Positions of the ignition 1. ACCESSORY, allows the electrical accessories such as the radio to operate while the engine is not running. 2. LOCK, locks the steering wheel, automatic transmission gearshift lever and allows key removal. For vehicles equipped with a manual transmission, you must depress the ignition release lever to release the key. 3. OFF, shuts off the engine and all accessories without locking the steering wheel. This position also allows the automatic transmission shift lever to be moved from the P (Park) position without the brake pedal being depressed. When the key is in the ignition and in the OFF position, the automatic transmission shift lever can be moved from the P (Park) position without the brake pedal depressed. To avoid unwanted vehicle movement, always set the parking brake. 4. ON, all electrical circuits operational. Warning lights illuminated. Key position when driving. 5. START, cranks the engine. Release the key as soon as 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, don’t press 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. 172 2007 F-250/350/450/550 (f23) Owners Guide (post-2002-fmt) USA (fus) Driving 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. 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 When the engine starts, the idle RPM runs faster to warm the engine. If the engine idle speed does not slow down automatically, have the vehicle checked. If your vehicle is operated in a heavy snow storm or blowing snow conditions, the engine air induction may become partially clogged with snow and/or ice. If this occurs, the engine may experience a significant reduction in power output. At the earliest opportunity, clear all the snow and/or ice away from the air induction inlet. The following starting instructions are for vehicles equipped with a gasoline engine; if your vehicle is equipped with a Diesel engine, refer to Starting the engine in your 6.0 Liter Power Stroke Direct Injection Turbo Diesel Owner’s Guide Supplement. Before starting the vehicle: 1. Make sure all occupants buckle 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 electrical accessories are off. 173 2007 F-250/350/450/550 (f23) Owners Guide (post-2002-fmt) USA (fus) Driving If starting a vehicle with an automatic transmission: 1. Make sure the parking brake is set. 2. Make sure the gearshift is in P (Park). If starting a vehicle with a manual transmission: 1. Make sure the parking brake is set. 2. Push the clutch pedal to the floor. 174 2007 F-250/350/450/550 (f23) Owners Guide (post-2002-fmt) USA (fus) • Turn the key to 4 (ON) without turning the key to 5 (START). Driving 175 2007 F-250/350/450/550 (f23) Owners Guide (post-2002-fmt) USA (fus) Driving Make sure the corresponding lights illuminate or illuminate briefly. If a light fails to illuminate, have the vehicle serviced. • If the driver’s safety belt is fastened, the Starting the engine 1. Turn the key to 4 (ON) without turning the key to 5 (START). 2.

Note: If the engine does not start within five seconds on the first try, turn the key to 3 (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. 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. 176 2007 F-250/350/450/550 (f23) Owners Guide (post-2002-fmt) USA (fus) Driving 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. USING THE ENGINE BLOCK HEATER (IF EQUIPPED) 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 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. The plug for the block heater is exposed in the front of the vehicle, beneath the grille. Vehicles equipped with a gasoline engine have the plug exposed on the driver side of the vehicle; vehicles equipped with a Diesel engine have the plug exposed on the passenger side of the vehicle. To reduce the risk of electrical shock, do not use your heater with ungrounded electrical systems or two-pronged (cheater) adapters. BRAKES Occasional brake noise is normal. If a metal-to-metal, continuous grinding or continuous squeal sound is present, the brake linings may be worn-out and should be inspected by your authorized dealer. If the vehicle has continuous vibration or shudder in the steering wheel while braking, the vehicle should be inspected by your authorized dealer. Refer to Brake system warning light in the Instrument Cluster chapter for information on the brake system warning light. BRAKE 177 2007 F-250/350/450/550 (f23) Owners Guide (post-2002-fmt) USA (fus) Driving Four-wheel anti-lock brake system (ABS) Your vehicle is equipped with an Anti-lock Braking System (ABS). This system helps you maintain steering control during emergency stops by keeping the brakes from locking. Noise from the ABS pump motor and brake pedal pulsation may be observed during ABS braking and the brake pedal may suddenly travel a little farther as soon as ABS braking is done and normal brake operation resumes. These are normal characteristics of the ABS and should be no reason for concern. ABS warning lamp The ABS lamp in the instrument cluster momentarily illuminates when the ignition is turned on. If the light does not illuminate during start up, remains on or flashes, the ABS may be disabled and may need to be serviced. Even when the ABS is disabled, normal braking is still effective. (If your BRAKE warning lamp illuminates with the parking brake released, have your brake system serviced immediately.) Using ABS When hard braking is required, apply continuous force on the brake pedal; do not pump the brake pedal since this will reduce the effectiveness of the ABS and will increase your vehicle’s stopping distance. The ABS will be activated immediately, allowing you to retain full steering control during hard braking and on slippery surfaces. However, the ABS does not decrease stopping distance. BRAKE ABS 178 2007 F-250/350/450/550 (f23) Owners Guide (post-2002-fmt) USA (fus) Parking brake To set the parking brake, press the parking brake pedal down until the pedal stops. Driving BRAKE The BRAKE warning lamp in the instrument cluster illuminates and remains illuminated until the parking brake is released. Pull the right side of the release lever to release the parking brake; the release lever pulls at an angle toward the driver’s door. To prevent the pedal from releasing too quickly, place your left foot on the parking brake pedal, then pull the release lever, making sure the pedal fully releases. You may want to pull the release lever again to make sure the parking brake is fully released. Always set the parking brake fully and make sure that the gearshift is securely latched in P (Park) (automatic transmission) or in 1 (First) (manual transmission). 179 2007 F-250/350/450/550 (f23) Owners Guide (post-2002-fmt) USA (fus) Driving Note: If your vehicle is equipped with a manual transmission, the engine may be required to run while power accessories operate and the parking brake is set. It is recommended that wheel chocks be used during this operation. If you’re parking your vehicle on a grade or with a trailer, press and hold the brake pedal down, then set the parking brake. There may be a little vehicle movement as the parking brake sets to hold the vehicle’s weight. This is normal and should be no reason for concern. If needed, press and hold the service brake pedal down, then try reapplying the parking brake. Chock the wheels if required. If the parking brake cannot hold the weight of the vehicle, the parking brake may need to be serviced or the vehicle may be overloaded. (below the FULL COLD mark on the dipstick). STEERING To help prevent damage to the power steering system: • Never hold the steering wheel at its furthest turning points (until it stops) for more than three to five seconds when the engine is running. • Do not operate the vehicle with a low power steering pump fluid level • Some noise is normal during operation. If excessive, check for low power steering pump fluid level before seeking service by your dealer. • Heavy or uneven efforts may be caused by low power steering fluid. Check for low power steering pump fluid level before seeking service by your dealer. • Do not fill the power steering pump reservoir above the FULL HOT mark on the dipstick, 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: • an improperly inflated tire • uneven tire wear • loose or worn suspension components • loose or worn steering components • improper steering alignment If any steering components are serviced or replaced, install new fasteners (many are coated with thread adhesive or have prevailing torque features which may not be re-used). Never re-use a bolt or nut. Torque fasteners to specifications in Workshop Manual. 180 2007 F-250/350/450/550 (f23) Owners Guide (post-2002-fmt) USA (fus) Driving A high crown in the road or high crosswinds may also make the steering seem to wander/pull. TRACTION-LOK 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 Traction-Lok axle functions like a standard rear axle. The axle may exhibit a slight noise or vibration in tight turns with low vehicle speed. This is normal behavior and indicates the axle is working. PREPARING TO DRIVE YOUR VEHICLE 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 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. 181 2007 F-250/350/450/550 (f23) Owners Guide (post-2002-fmt) USA (fus) Driving AUTOMATIC TRANSMISSION OPERATION (IF EQUIPPED) Brake-shift interlock This vehicle is equipped with a brake-shift interlock feature that prevents the gearshift lever from being moved from P (Park) when the ignition is in the 4 (ON) position unless brake pedal is depressed. If you cannot move the gearshift lever out of P (Park) with ignition in the 4 (ON) position and the brake pedal depressed: 1. Apply the parking brake, turn ignition key to 2 (LOCK), then remove the key. 2. Insert the key and turn it to 3 (OFF). Apply the brake pedal and shift to N (Neutral). When the key is in the ignition and in the OFF position, the automatic transmission shift lever can be moved from the P (Park) position without the brake pedal depressed. To avoid unwanted vehicle movement, always set the parking brake. 3. Start the vehicle. If it is necessary to use the above procedure to move the gearshift lever, 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. Do not drive your vehicle until you verify that the brakelamps are working. 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. 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 as soon as possible. 182 2007 F-250/350/450/550 (f23) Owners Guide (post-2002-fmt) USA (fus) Understanding the shift positions of the 5–speed automatic transmission Driving This vehicle is equipped with an adaptive Transmission Shift Strategy. Adaptive Shift Strategy offers the optimal transmission operation and shift quality. When the vehicle’s battery has been disconnected for any type of service or repair, the transmission will need to relearn the normal shift strategy parameters, much like having to reset your radio stations when your vehicle battery has been disconnected. The Adaptive Transmission Strategy allows the transmission to relearn these operating parameters. This learning process could take several transmission upshifts and downshifts; during this learning process, slightly firmer shifts may occur. After this learning process, normal shift feel and shift scheduling will resume. P (Park) This position locks the transmission and prevents the rear wheels from turning. To put your vehicle in gear: • Start the engine • Depress the brake pedal • Move the gearshift lever into the desired gear 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). 183 2007 F-250/350/450/550 (f23) Owners Guide (post-2002-fmt) USA (fus) Driving 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 (Overdrive) with Tow/Haul OFF D (Overdrive) with Tow/Haul OFF is the normal driving position for the best fuel economy. The overdrive function allows automatic upshifts and downshifts through gears one through five. D (Overdrive) with Tow/Haul ON The Tow/Haul feature improves transmission operation when towing a trailer or a heavy load. All transmission gear ranges are available when using Tow/Haul. To activate Tow/Haul, press the button on the end of the gearshift lever. The TOW HAUL indicator light will illuminate in the instrument cluster. Tow/Haul delays upshifts to reduce frequency of transmission shifting. Tow/Haul also provides engine braking in all forward gears when the transmission is in the D (Overdrive) position; this engine braking will slow the vehicle and assist the driver in controlling the vehicle when descending a grade. Depending on driving conditions and load conditions, the transmission may downshift, slow the vehicle and control the vehicle speed when descending a hill, without the accelerator pedal being pressed. The amount of downshift braking provided will vary based upon the amount the brake pedal is depressed. To deactivate the Tow/Haul feature and return to normal driving mode, press the button on the end of the gearshift lever. The TOW HAUL light will no longer be illuminated. When you shut-off and restart the engine, the transmission will automatically return to normal D (Overdrive) mode (Tow/Haul OFF). Do not use the Tow/Haul feature when driving in icy or slippery conditions as the increased engine braking can cause the rear wheels to slide and the vehicle to swing around with the possible loss of vehicle control. 184 2007 F-250/350/450/550 (f23) Owners Guide (post-2002-fmt) USA (fus) Driving 3 (Third) Transmission starts and operates in third gear only. Used for improved traction on slippery roads. Selecting 3 (Third) provides engine braking. 2 (Second) Use 2 (Second) to start-up on slippery roads or to provide additional engine braking on downgrades. 1 (First) • Provides maximum engine braking. • Allows upshifts by moving gearshift lever. • The transmission will not downshift into 1 (First) at high speeds; it will downshift to a lower gear and then shift into 1 (First) when the vehicle reaches slower speeds. (Overdrive) or D (Drive). Forced downshifts • Allowed in • Depress the accelerator to the floor. • Allows transmission to select an appropriate gear. If your vehicle gets stuck in mud or snow If your vehicle gets stuck in mud or snow, it may be rocked out by shifting between forward and reverse gears, stopping between shifts in a steady pattern. Press lightly on the accelerator in each gear. Do not rock the vehicle if the engine is not at normal operating temperature or damage to the transmission may occur. Do not rock the vehicle for more than a minute or damage to the transmission and tires may occur, or the engine may overheat. MANUAL TRANSMISSION OPERATION (IF EQUIPPED) 3 D 2 4 Using the clutch The manual transmission has a starter interlock that prevents cranking the engine unless the clutch pedal is fully depressed.
