proper buckle for that seating positions until you hear a snap and feel it latch. Make sure the tongue is securely latched to the buckle by pulling on the tongue.


5. Remove remaining slack from the belt. Force the seat down with extra weight, e.g., by pressing down or kneeling on the child restraint while pulling up on the shoulder belt in order to force slack from the belt. This is necessary to remove the remaining slack that will exist once the additional weight of the child is added to the child restraint. It also helps to achieve the proper snugness of the child seat to the vehicle. Sometimes, a slight lean towards the buckle will additionally help to remove remaining slack from the belt.

6. Attach the tether strap (if the child seat is equipped). Refer to Attaching child safety seats with tether straps later in this chapter. 7. Before placing the child in the seat, forcibly move the seat forward and back to make sure the seat is securely held in place. To check this, grab the seat at the belt path and attempt to move it side to side and forward. There should be no more than 1 inch (2.5 cm) of movement for proper installation. 8. Ford recommends checking with a NHTSA Certified Child Passenger Safety Technician (CPST) to make certain the child restraint is properly installed. In Canada, check with your local St. John Ambulance office for referral to a CPST.


Attaching child safety seats with LATCH (Lower Anchors and Tethers for CHildren) attachments The LATCH system is composed of three vehicle anchor points: two (2) lower anchors located where the vehicle seat back and seat cushion meet (called the “seat bight”) and one (1) top tether anchor located behind that seating position. Your vehicle is not equipped with the lower anchor points in the seat bight. For this vehicle use the vehicle safety belt and upper tether to secure a child seat. See Attaching child safety seats with tether straps and Recommendations for attaching safety restraints for children in this chapter for more information.


Attaching child safety seats with tether straps Many forward-facing child safety seats include a tether strap which extends from the back of the child safety seat and hooks to an anchoring point called the top tether anchor. Tether straps are available as an accessory for many older safety seats. Contact the manufacturer of your child seat for information about ordering a tether strap, or to obtain a longer tether strap if the tether strap on your safety seat does not reach the appropriate top tether anchor in the vehicle. The passenger seats of your vehicle may be equipped with built-in tether strap anchors located behind the seats as described below. The tether anchors in your vehicle may be straps on the seatback or an anchor bracket mounted to the body shell on the back panel. 206

Seating and Safety Restraints


Attach the tether strap only to the appropriate tether anchor as shown. The tether strap may not work properly if attached somewhere other than the correct tether anchor. Once the child safety seat has been installed using the safety belt, you can attach the top tether strap. Tether strap attachment 1. Route the child safety seat tether strap over the back of the seat. For vehicles with adjustable head restraints, route the tether strap under the head restraint and between the head restraint posts, other wise route the tether strap over the top of the seatback. If the top of the safety seat hits the head restraint, raise the head restraint to let the child seat fit further rearward. 2. Locate the correct anchor for the selected seating position. 3. 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. 4. Remove tether cover.

5. Clip the tether strap to the anchor as shown. • Front seats (Regular Cab)


• Rear seats (Crew Cab)


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 with automatic locking mode combination lap and shoulder belts and Installing child safety seats in cinch tongue combination lap and shoulder belt seating positions sections 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. If your child restraint system is equipped with a tether strap, and the child restraint manufacturer recommends its use, Ford also recommends its use.

Seating and Safety Restraints


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. These straps may be secured below the back of the seat with rubber bands. To access, reach below the back of the seat and pull tether loop out of the rubber band securing it. 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: 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.


Child booster seats The belt-positioning booster (booster seat) is used to improve the fit of the vehicle safety belt. Children outgrow a typical child seat (e.g., convertible or toddler seat) when they weigh about 40 lb (18 kg) and are around four (4) years of age. Consult your child safety seat owner guide for the weight, height, and age limits specific to your child safety seat. Keep your child in the child safety seat if it properly fits the child, remains appropriate for their weight, height and age AND if properly secured to the vehicle. Although the lap/shoulder belt will provide some protection, children who have outgrown a typical child seat are still too small for lap/shoulder belts to fit properly, and wearing an improperly fitted vehicle safety belt could increase the risk of serious injury in a crash. To improve the fit of both the lap and shoulder belt on children who have outgrown child safety seats, Ford Motor Company recommends use of a belt-positioning booster. Booster seats position a child so that vehicle lap/shoulder safety belts fit better. They lift the child up so that the lap belt rests low across the hips and the knees bend comfortably at the edge of the cushion, while minimizing slouching. Booster seats may also make the shoulder belt fit better and more comfortably. Try to keep the belt near the middle of the shoulder and across the center of the chest. Moving the child closer (a few centimeters or inches) to the center of the vehicle, but remaining in the same seating position, may help provide a good shoulder belt fit.

Seating and Safety Restraints


When children should use booster seats Children need to use booster seats from the time they outgrow the toddler seat until they are big enough for the vehicle seat and lap/shoulder belt to fit properly. Generally this is when they reach a height of at least 4 feet 9 inches (1.45 meters) tall (around age eight to age twelve and between 40 lb (18 kg) and 80 lb (36 kg) or upward to 100 lb (45 kg) if recommended by your child restraint manufacturer). Many state and provincial laws require that children use approved booster seats until they reach age eight, a height of 4 feet 9 inches (1.45 meters) tall, or 80 lb (36 kg). Booster seats should be used until you can answer YES to ALL of these questions when seated without a booster seat: • Can the child sit all the way back against the vehicle seat back with knees bent comfortably at the edge of the seat cushion? • Can the child sit without • Does the lap belt rest low across • Is the shoulder belt centered on the shoulder and chest? • Can the child stay seated like this for the whole trip?

Seating and Safety Restraints


Types of booster seats There are generally two types of belt-positioning booster seats: backless and high back. Always use booster seats in conjunction with the vehicle lap/shoulder belt. • Backless booster seats


If your backless booster seat has a removable shield, remove the shield. If a vehicle seating position has a low seat back or no head restraint, a backless booster seat may place your child’s head (as measured at the tops of the ears) above the top of the seat. In this case, move the backless booster to another seating position with a higher seat back or head restraint and lap/shoulder belts, or consider using a high back booster seat.


• High back booster seats


If, with a backless booster seat, you cannot find a seating position that adequately supports your child’s head, a high back booster seat would be a better choice.


213


2012 F-250/350/450/550 (f23) Owners Guide, 4th Printing USA (fus)


Seating and Safety Restraints


Children and booster seats vary in size and shape. Choose a booster that keeps the lap belt low and snug across the hips, never up across the stomach, and lets you adjust the shoulder belt to cross the chest and rest snugly near the center of the shoulder. The drawings below compare the ideal fit (center) to a shoulder belt uncomfortably close to the neck and a shoulder belt that could slip off the shoulder. The drawings below also show how the lap belt should be low and snug across the child’s hips.


If the booster seat slides on the vehicle seat, placing a rubberized mesh sold as shelf or carpet liner under the booster seat may improve this condition. Do not introduce any item thicker than this under the booster seat. Check with the booster seat manufacturer’s instructions. The importance of shoulder belts Using a booster without a shoulder belt increases the risk of a child’s head hitting a hard surface in a collision. For this reason, you should never use a booster seat with a lap belt only. It is generally best to use a booster seat with lap/shoulder belts in the back seat. Move a child to a different seating location if the shoulder belt does not stay positioned on the shoulder during use. 214


2012 F-250/350/450/550 (f23) Owners Guide, 4th Printing USA (fus)


Seating and Safety Restraints


Follow all instructions provided by the manufacturer of the booster seat.


WARNING: Never place, or allow a child to place, the shoulder belt under a child’s arm or behind the back because it reduces


the protection for the upper part of the body and may increase the risk of injury or death in a collision.


Child restraint and safety belt maintenance Inspect the vehicle safety belts and child safety seat systems periodically to make sure they work properly and are not damaged. Inspect the vehicle and child seat safety belts to make sure there are no nicks, tears or cuts. Replace if necessary. All vehicle safety belt assemblies, including retractors, buckles, front safety belt buckle assemblies, buckle support assemblies (slide bar-if equipped), shoulder belt height adjusters (if equipped), shoulder belt guide on seatback (if equipped), child safety seat LATCH and tether anchors, and attaching hardware, should be inspected after a collision. Refer to the child restraint manufacturer’s instructions for additional inspection and maintenance information specific to the child restraint. Ford Motor Company recommends that all safety belt assemblies in use in vehicles involved in a collision be replaced. However, if the collision was minor and an authorized dealer finds that the belts do not show damage and continue to operate properly, they do not need to be replaced. Safety belt assemblies not in use during a collision should also be inspected and replaced if either damage or improper operation is noted. For proper care of soiled safety belts, refer to Interior in the Cleaning chapter.


WARNING: Failure to inspect and if necessary replace the safety belt assembly or child restraint system under the above


conditions could result in severe personal injuries in the event of a collision.

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.


WARNING: 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.


WARNING: In a rollover crash, an unbelted person is significantly more likely to die than a person wearing a seat belt.


All occupants must wear seat 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


Four-wheel drive (4WD) system (if equipped) A vehicle equipped with 4WD (when selected) 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. 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 transfer case operation and shifting procedures can be found in the Driving chapter. Information on transfer case maintenance can be found in the Maintenance and Specifications chapter. 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.


WARNING: Do not become overconfident in the ability of 4WD vehicles. Although a 4WD 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 SUVs 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.


• Narrower – to provide greater maneuverability in tight spaces, particularly in off-road use.


As a result of the above dimensional differences, SUVs 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 Tire Quality Grades apply to new pneumatic passenger car tires. 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 passenger car tires. They do not apply to deep tread, winter-type snow tires, space-saver or temporary use spare tires, light truck or “LT” type 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 Motor Company 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 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


WARNING: The traction grade assigned to this tire is based on straight-ahead braking traction tests, and does not include


acceleration, cornering, hydroplaning or peak traction characteristics.


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.

Tires, Wheels and Loading


Temperature A B C


WARNING: The temperature grade for this tire is established for a tire that is properly inflated and not overloaded. Excessive


speed, underinflation, or excessive loading, either separately or in combination, can cause heat buildup and possible tire failure.


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. 139. Grades B and A represent higher levels of performance on the laboratory test wheel than the minimum required by law.


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.


• 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. 220

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. 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.


WARNING: 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!


221

Tires, Wheels and Loading


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. 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 (affixed to either the door hinge pillar, door-latch post, or the door edge that meets the door-latch post, next to the driver’s seating position), 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. Note: Do not reduce tire pressure to change the ride characteristics of the vehicle. If you do not maintain the inflation pressure at the levels specified by Ford, your vehicle may experience a condition known as “shimmy”. Shimmy is a severe vibration and oscillation in the steering wheel after the vehicle travels over a bump or dip in the road that does not dampen out by itself. Shimmy may result from significant under-inflation of the tires, improper tires (load range, size, or type), or vehicle modifications such as lift-kits. In the event that your vehicle experiences shimmy, you should slowly reduce speed by either lifting off the accelerator pedal or lightly applying the brakes. The shimmy will cease as the vehicle speed decreases. 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 (affixed to either the door hinge pillar, door-latch post, or the door edge that meets the door-latch post, next to the driver’s seating position), 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.

Tires, Wheels and Loading


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. 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 the Dissimilar spare tire/wheel information section for description): Store and maintain at 60 psi (4.15 bar). For full-size and dissimilar spare tires (see the 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. 223

Tire Inflation Information


WARNING: An inflated tire and rim can be very dangerous if improperly used, serviced or maintained. To reduce the risk of


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.


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 tire 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.

TIRE CARE


Inspecting your tires and wheel valve stems 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 the tire and valve stems for holes, cracks, or cuts that may permit air leakage and repair or replace the tire and replace the valve stem. 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.


225


2012 F-250/350/450/550 (f23) Owners Guide, 4th Printing 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.


WARNING: 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.

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


WARNING: 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 (affixed to either the door hinge pillar, door-latch post, or the door edge that meets the door-latch post, next to the driver’s seating position), 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 contact your authorized dealer as soon as possible. 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, contact your authorized dealer as soon as possible.

Tires, Wheels and Loading


WARNING: 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 (138 kPa) 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 ft (3.66 m) away from the tire wheel assembly. 4. Use both eye and ear protection. For a mounting pressure more than 20 psi (138 kPa) greater than the maximum pressure, an authorized 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 (3.66 m) away from the tire wheel assembly.


Your vehicle is equipped with tires designed to provide a safe ride and handling capability. 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 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 equipped). 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(if equipped).

Safety Practices


WARNING: 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.


WARNING: Do not spin the wheels at over 35 mph (56 km/h). The tires may fail and injure a passenger or bystander.


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 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 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


WARNING: If the tire label shows different tire pressures for the front and rear tires and the vehicle is equipped with TPMS


(tire pressure monitoring system), then the settings for the TPMS sensors need to be updated. Always perform the TPMS reset procedure after tire rotation. If the system is not reset, it may not provide a low tire pressure warning when necessary. See the TPMS reset procedure in this chapter.


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 and wheel assembly. A dissimilar spare tire/wheel is defined as a spare tire or wheel that is different in brand, size or appearance from the road tires and wheels. If you have a dissimilar spare tire and wheel assembly, 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. Rotating your tires at the recommended interval (as indicated in the Scheduled Maintenance chapter) will help your tires wear more evenly, providing better tire performance and longer tire life. • Rear-wheel drive (RWD)

TIRE PRESSURE MONITORING SYSTEM (TPMS) (IF EQUIPPED)


WARNING: 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.


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. Your vehicle has also been equipped with a TPMS malfunction indicator to indicate when the system is not operating properly. The TPMS malfunction indicator is combined with the low tire pressure telltale. When the system detects a malfunction, the telltale will flash for approximately one minute and then remain continuously illuminated. This sequence will continue upon subsequent vehicle start-ups as long as the malfunction exists. When the malfunction indicator is illuminated, the system may not be able to detect or signal low tire pressure as intended. TPMS malfunctions may occur for a variety of reasons, including the installation of


237

Tires, Wheels and Loading


replacement or alternate tires or wheels on the vehicle that prevent the TPMS from functioning properly. Always check the TPMS malfunction telltale after replacing one or more tires or wheels on your vehicle to ensure that the replacement or alternate tires and wheels allow the TPMS to continue to function properly. 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.


Changing Tires with a TPMS Note: Each road tire is equipped with a tire pressure sensor located inside the tire and wheel assembly cavity. The pressure sensor is attached to the valve stem. The pressure sensor is covered by the tire and is not visible unless the tire is removed. 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 The tire pressure monitoring system measures pressure in your four road tires and sends the tire pressure readings to your vehicle. The low tire pressure warning light 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. Visit www.checkmytires.org for additional information. When your temporary spare tire is installed When one of your road tires needs to be replaced with the temporary spare, the TPMS 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. 238


2012 F-250/350/450/550 (f23) Owners Guide, 4th Printing USA (fus)


Tires, Wheels and Loading


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 a 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 no longer capable of functioning as intended. Refer to the following chart for information concerning your tire pressure monitoring system: Low tire pressure warning light Solid warning light

1. Make sure tires are at the proper pressure. See Inflating your tires in this chapter. 2. After inflating your tires to the manufacturer’s recommended 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 turns off. Spare tire 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 the tires are properly inflated and the spare tire is not in use but the light remains on, contact your authorized dealer as soon as possible. On vehicles with different front and rear tire pressures, the TPMS must be retrained following every tire rotation. See Tire rotation in this chapter.

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 overnight with the outside temperature significantly lower than the daytime temperature, the tire pressure may decrease approximately 3 psi (21 kPa) for a drop of 30°F (17°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 light 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 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. 240

TPMS Reset Procedure


WARNING: To determine the required pressure(s) for your vehicle, refer to the Safety Compliance Certification Label


(affixed to either the door hinge pillar, door-latch post, or the door edge that meets the door-latch post, next to the driver’s seating position), or Tire Label located on the B-Pillar or the edge of the driver’s door. See Load Carrying for more information.


Note: The TPMS reset procedure needs to be performed after each tire rotation on vehicles that require different recommended tire pressures in the front tires as compared to the rear tires. Overview To provide the vehicle’s load carrying capability, some vehicles require different recommended tire pressures in the front tires as compared to the rear tires. The tire pressure monitoring system equipped on these vehicles is designed to illuminate the low tire pressure warning light at two different pressures; one for the front tires and one for the rear tires. Since tires need to be rotated to provide consistent performance and maximum tire life, the tire pressure monitoring system needs to know when the tires are rotated to determine which set of tires are on the front and which are on the rear. With this information, the system can detect and properly warn of low tire pressures. TPMS reset tips: • To reduce the chances of interference from another vehicle, the TPMS reset procedure should be performed at least three feet (one meter) away from another Ford Motor Company vehicle undergoing the TPMS reset procedure at the same time. • Do not wait more than two minutes between resetting each tire sensor


or the system will time-out and the entire procedure will have to be repeated on all four wheels.


• A double horn chirp indicates the need to repeat the procedure. Performing the TPMS Reset Procedure It is recommended that you read the entire procedure before attempting. 1. Drive the vehicle above 20 mph (32 km/h) for at least two minutes and then park in a safe location where you can easily get to all four tires and have access to an air pump. 2. Place the ignition in the off position and keep the key in the ignition.

Remove the valve cap from the valve stem on the left front tire; decrease the air pressure until the horn sounds. Note: The single horn chirp confirms that the sensor identification code has been learned by the module for this position. If a double horn is heard, the reset procedure was unsuccessful, and must be repeated.

7. Remove the valve cap from the valve stem on the right front tire; decrease the air pressure until the horn sounds. 8. Remove the valve cap from the valve stem on the right rear tire; decrease the air pressure until the horn sounds. 9. Remove the valve cap from the valve stem on the left rear tire; decrease the air pressure until the horn sounds. Training is complete after the horn sounds for the last tire trained (driver’s side rear tire), the TPMS indicator stops flashing, and the message center (if equipped) displays a message. 10. Turn the ignition off. If two short horn beeps are heard, the reset procedure was unsuccessful and must be repeated. If after repeating the procedure and two short beeps are heard when the ignition is turned to off, seek assistance from your authorized dealer. 11. Set all four tires to the recommended air pressure as indicated on the Safety Compliance Certification Label (affixed to either the door hinge pillar, door-latch post, or the door edge that meets the door-latch post, next to the driver’s seating position) or Tire Label located on the B-Pillar or the edge of the driver’s door. See Load Carrying for more information.


USING SNOW CHAINS


WARNING: Snow tires must be the same size, load index, speed rating as those originally provided by Ford. 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.


Note: Do not use snow chains on vehicles with 20 inch 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. Note: The suspension insulation and bumpers will help prevent vehicle damage. Do not remove these components from your vehicle when using snow tires and chains.


243

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.


244

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 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.


WARNING: 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.

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)


WARNING: Do not exceed the GVWR or the GAWR specified on the Safety Compliance Certification Label.

Tires, Wheels and Loading


WARNING: 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.


WARNING: 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 lb.” 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 lb. 4. The resulting figure equals the available amount of cargo and luggage load capacity. For example, if the “XXX” amount equals 1,400 lb. and there will be five 150 lb. passengers in your vehicle, the amount of available cargo and luggage load capacity is 650 lb. (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 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: 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.

Tires, Wheels and Loading • 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: 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. The label shall be affixed to either the door hinge pillar, door-latch post, or the door edge that meets the door-latch post, next to the driver’s seating position.


Special loading instructions for owners of pick-up trucks and utility-type vehicles


WARNING: 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’s guide.


WARNING: 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 chart in this section applies to vehicles equipped with a gasoline engine; for vehicles equipped with a diesel engine, refer to your diesel 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 for your engine and rear axle ratio. 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. To find the maximum trailer weight allowed for your vehicle, consult your authorized dealer (or the RV and Trailer Towing Guide provided by your authorized dealer). To calculate your maximum trailer weight on your own: 1. Pick-up trucks: Take curb weight, hitch hardware and the driver’s weight, then subtract them from the GCWR listed for your vehicle series and drive axle ratio listed on the following table.


2. Chassis cabs and pick-up 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 and drive axle ratio listed on the following table.


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. This information follows the table listing the maximum GCWRs. For load specification terms found on the label and instructions on calculating your vehicle’s load, refer to Vehicle loading - with and without a trailer in this chapter when figuring the total weight of your vehicle. Note: Do not exceed the tire ratings specified on the Tire Label or Safety Compliance Certification Label.


WARNING: Do not exceed the GVWR or the GAWR specified on the certification label.

Hitches


WARNING: ON PICK-UP TRUCKS, the trailer hitch provided on this vehicle enhances collision protection for the fuel system. DO


NOT REMOVE!


Do not mount a ball hitch (sometimes referred to as a trailer ball hitch or trailer ball) to the bumper or use a hitch that clamps onto the vehicle’s bumper or attaches to the axle. You must distribute the load in your trailer so that 10–15% for conventional towing or 15–25% for fifth-wheel towing of the total weight of the trailer is on the tongue. Hitch ratings The standard 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.

To determine which trailer hitch your vehicle is equipped with, refer to the trailer hitch label located on trailer hitch cross tube. Once you determine which trailer hitch you have consult your authorized dealer, the RV and Trailer Towing Guide provided by your dealer or online at https://www.fleet.ford.com/showroom/rv_trailer_towing/default.asp.


WARNING: The hitch rating listed on the trailer hitch label are maximum possible trailer ratings for that hitch but may not be what your vehicle is capable of towing. To find the maximum trailer weight allowed for your specific vehicle, consult your authorized dealer (or the RV and Trailer Towing Guide provided by your authorized dealer).


WARNING: 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.


Weight-Distributing Hitches When hooking-up a trailer using a weight-distributing hitch, always use the following procedure: 1. Park the vehicle (without the trailer) on a level surface. 2. Measure the height of the top of the front wheel opening on the fender, this is H1. 3. Attach the trailer to the vehicle without the weight distributing bars connected. 4. Measure the height of the top of the front wheel opening on the fender a second time, this is H2. 5. Install and adjust the tension in the weight distributing bars so that the height of the front fender is approximately halfway between H1 and H2. 6. Check that the trailer is level. If not level, adjust the ball height accordingly and repeat Steps 3–6.


WARNING: Do not adjust a weight-distributing hitch to any position where the rear bumper of the vehicle is higher than it was before attaching the trailer. Doing so will defeat the function of the weight-distributing hitch, which may cause unpredictable handling, and could result in serious personal injury.

Fifth-wheel trailer hitch (if equipped) To find the maximum trailer weight allowed for your vehicle, consult your authorized dealer (or the RV and Trailer Towing Guide provided by your authorized dealer). Fifth-wheel and gooseneck towing Your vehicle may be equipped with a fifth-wheel prep package. This package enables your vehicle to accept certain fifth-wheel trailer hitches and gooseneck ball hitches. The fifth-wheel trailer hitch is attached to the four mounting pads in the pick-up bed; an optional 7–pin connector provided in the bed as well. Alternatively, if a gooseneck ball hitch is used, the ball is attached to the tube in the center of the bed. Shorter pick-up boxes (e.g. 6’ 6” F-250/350) provide less clearance between the cab and fifth-wheel/gooseneck trailer compared to “long box” pick-ups. When selecting a trailer and tow vehicle, it’s critical that this combination provide clearance between the cab and tow vehicle for turns up to and including 90 degrees. Failure to follow this recommendation could result in the trailer contacting the cab of the tow vehicle during tight turns that are typical during low-speed parking and turning maneuvers. This contact could result in damage to the trailer and tow vehicle.


WARNING: The mounting pads in the bed are specifically designed for certain fifth-wheel trailer hitches and gooseneck ball


hitches. Do not use these mounting pads for other purposes. Doing so could result in vehicle structural damage, loss of vehicle control, and personal injury. Contact your authorized dealer to purchase gooseneck and fifth-wheel hitches that are compatible with your vehicle.


WARNING: Towing trailers beyond the maximum limit of the towing system could result in vehicle structural damage, loss of


vehicle control and personal injury.


Fifth-wheel and gooseneck hitch ratings


WARNING: The hitch rating listed on the trailer hitch label is the maximum possible trailer rating. To find the maximum trailer weight allowed for your specific vehicle, consult your authorized dealer or the RV and Trailer Towing Guide provided by your authorized dealer.

Safety Chains Note: Do not attach safety chains to the bumper. 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.


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.


WARNING: 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, which could result in loss of vehicle control, crash or serious injury.


The braking system of the tow vehicle is rated for operation at the GVWR not GCWR. 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 been tested to be compatible with several major brands of electric-over-hydraulic trailer brakes; contact your authorized dealer for information on which brands can be used.


WARNING: The Ford TBC has been verified to be compatible with trailers having electric-actuated drum brakes (one to four axles) and some electric-over-hydraulic types, but not hydraulic surge 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. Failure to do so may result in loss of vehicle control, crash or serious injury.

The TBC user interface consists of the following: 1. +/- (GAIN adjustment buttons): Pressing these buttons adjusts 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 raises or lowers the setting continuously. The gain setting displays in the message center as follows: TBC GAIN = XX.X. The trailer brake controller (TBC) is designed to display three items of information in the instrument cluster message center. These are: gain setting, output bar graph, and trailer connectivity status. They appear in the message center as follows: • TBC GAIN = XX.X NO TRAILER: The instrument cluster message center displays the current gain setting during a given ignition cycle and when adjusting the gain. This message is also displayed during manual activation without a trailer connected or when gain adjustments are made with no trailer connected.


• TBC GAIN = XX.X OUTPUT = //////: When the vehicle’s brake pedal


is pushed, or when the manual control is activated, bar indicators illuminate in the instrument cluster message center to indicate the amount of power going to the trailer brakes relative to the brake pedal or manual control input. One bar indicates the least amount of output with six bars indicating maximum output. • TRAILER CONNECTED: This message is displayed when a correct


trailer wiring connection (a trailer with electric trailer brakes) has been sensed during a given ignition cycle.


• TRAILER DISCONNECTED: This message is displayed and accompanied by a single chime, 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 truck or trailer wiring fault occurs causing the trailer to appear disconnected. This message is also displayed during manual activation without a trailer connected.

2. 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 illuminates both


the trailer brake lamps and the tow vehicle brake lamps except the center high-mount stop lamp (presuming proper trailer electrical connection). Pressing the vehicle brake pedal also illuminates both trailer and vehicle brake lamps. Procedure for adjusting 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. 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 CONNECTED message displays in the instrument cluster message center. 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. 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 lock-up may not be attainable even with the maximum GAIN setting of 10.

Explanation of instrument cluster warning messages: The TBC interacts with the instrument cluster message center to display the following messages: TRAILER BRAKE MODULE FAULT: This message is displayed and accompanied by a single chime, in response to faults sensed by the TBC. In the event this message is seen, please contact your authorized dealer as soon as possible for diagnosis and repair. The TBC may still function, but performance may be degraded. WIRING FAULT ON TRAILER: This message is displayed when a Short circuit on the electric brake output wire has occurred. If the WIRING FAULT ON TRAILER message is displayed and accompanied by a single chime, with no trailer connected, the problem is with the vehicle wiring from the TBC to the 7–pin connector at 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) or trailer brakes drawing too much current. 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. 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) 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 is equipped with a feature which reduces output at vehicle speeds below 11 mph (18 km/h) so trailer and vehicle braking is not jerky or harsh. This feature is only available when applying the brakes using the vehicle’s brake pedal, not the TBC.

Tires, Wheels and Loading • The TBC interacts with the brake system of the vehicle, including


ABS, in order to reduce the likelihood of trailer wheel lock-up; therefore, if these systems are not functioning properly, the TBC may not function at full performance.


• Your vehicle’s brake system and the trailer brake system work


independently of each other; changing the GAIN setting on the TBC does not affect the operation of your vehicle’s brakes whether a trailer is attached or not.


• When the vehicle is turned off, the TBC output is disabled and the display is shut down; turning the ignition from off to on awakens 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. Contact your authorized dealer or trailer rental agency for proper instructions and equipment for hooking-up trailer lamps.


Driving while you tow When towing a trailer: • Consult your local motor vehicle laws for towing a trailer. • Do not drive faster than 70 mph (113 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. • Activate the tow/haul feature to eliminate excessive transmission


shifting and assist in transmission cooling. For additional information, refer to Automatic transmission operation in the Driving chapter. • Allow more distance for stopping with a trailer attached; anticipate
