CLEANING THE EXTERIOR Wash your vehicle regularly with cool or lukewarm water and a neutral pH shampoo, such as Motorcraft Detail Wash. • Never use strong household detergents
or soap, such as dish washing or laundry liquid. These products can discolor and spot painted surfaces.
• Never wash a vehicle that is “hot to the
touch” or during exposure to strong, direct sunlight.
•
• Dry your vehicle with a chamois or soft terry cloth towel in order to eliminate water spotting. Immediately remove items such as gasoline, diesel fuel, bird droppings and insect deposits because they can cause damage to your vehicle’s paintwork and trim over time. Use Motorcraft Bug and Tar Remover.
• Remove any exterior accessories, such
as antennas, before entering a car wash.
Note: Suntan lotions and insect repellents can damage any painted surface; if these substances come in contact with your vehicle, wash off as soon as possible. Stripes or Graphics (if equipped) Do not use a commercial or high-pressure sprayer on the surface or edge of stripes and graphics. This can cause damage to the film and cause the edge of the film to peel away from the vehicle surface. Exterior Chrome Note: Never use abrasive materials such as steel wool or plastic pads as they can scratch the chrome surface. Note: Do not use chrome cleaner, metal cleaner or polish on wheels and wheel covers

Vehicle Care
• Use a quality wax that does not contain
abrasives. Follow the manufacturer’s instructions to apply and remove the wax.
•
• Apply a small amount of wax in a
back-and-forth motion, not in circles. • Do not allow wax to come in contact with any non-body (low-gloss black) colored trim. The wax will discolor or stain the parts over time. • Roof racks. • Bumpers. • Grained door handles. • Side moldings. • Mirror housings. • Windshield cowl area.
• Do not apply wax to glass areas. • After waxing, your car's paint should
feel smooth, and be free of streaks and smudges.
CLEANING THE ENGINE Engines are more efficient when they are clean because grease and dirt buildup keep the engine warmer than normal. When washing: •
Take care when using a power washer to clean the engine. The high-pressure fluid could penetrate the sealed parts and cause damage.
•
• Do not spray a hot engine with cold water to avoid cracking the engine block or other engine components. Spray Motorcraft Engine Shampoo and Degreaser on all parts that require cleaning and pressure rinse clean. In Canada, use Motorcraft Engine Shampoo.
• Never wash or rinse the engine while it is hot or running; water in the running engine may cause internal damage.
• Wash your vehicle first, using cool or
lukewarm water and a neutral pH shampoo, such as Motorcraft Detail Wash.
• Use Motorcraft Custom Bright Metal
Cleaner. Apply the product as you would a wax to clean bumpers and other chrome parts; allow the cleaner to dry for a few minutes, then wipe off the haze with a clean, dry rag.
• Do not apply cleaning product to hot
surfaces and do not leave cleaning product on chrome surfaces longer than the time recommended.
• Using other non-recommended cleaners can result in severe and permanent cosmetic damage.
Underbody Flush the complete underside of your vehicle frequently. Keep body and door drain holes free from packed dirt. Cleaning Plastic Exterior Parts Use only approved products to clean plastic parts •
For routine cleaning, use Motorcraft Detail Wash. If tar or grease spots are present, use Motorcraft Bug and Tar Remover.
•
WAXING Regular waxing is necessary to protect your car's paint from the elements. We recommend that you wash and wax the painted surface once or twice a year. When washing and waxing, park your vehicle in a shaded area out of direct sunlight. Always wash your vehicle before applying wax.

• Never wash or rinse any ignition coil, spark plug wire or spark plug well, or the area in and around these locations.
• Cover the battery, power distribution box, and air filter assembly to prevent water damage when cleaning the engine.
CLEANING THE EXHAUST
WARNINGS
Failure to maintain the functional holes, in the tailpipe section of the exhaust, clean and free of debris or
foreign material may result in the holes becoming blocked or plugged. Do not modify or remove the tail-pipe section. Blocked or plugged holes or removal/modification of the system could result in elevated exhaust gas temperatures which may result in vehicle/property damage or personal injury.
The normal operating temperature of the exhaust system is very high. Never work around or attempt to
repair any part of the exhaust system until it has cooled. Use special care when working around the diesel oxidation catalytic converter and/or the diesel particulate filter (DPF). The diesel oxidation catalytic converter and/or the DPF heats up to a high temperature after only a short period of engine operation and can stay hot even after the engine is turned off. Failure to follow these instructions may result in personal injury.
249
Super Duty (TFA)
The visible holes in the exhaust tip and the holes under the shield just inboard of the right rear tire(s) are functional. The holes need to be kept clear of mud/debris or foreign material to maintain proper function of the exhaust system. Clean and remove debris or foreign material if present as needed. Spraying with a hose during regular washing of vehicle should help keep holes clean and clear of debris or foreign material. CLEANING THE WINDOWS AND WIPER BLADES Car wash chemicals and environmental fallout can result in windshield and wiper blade contamination. Dirty windshield and wipers will result in poor windshield wiper operation. Keep the windshield and wiper blades clean to maintain windshield wiper performance. To clean the windshield and wiper blades: • Clean the windshield with a non-abrasive glass cleaner. For windshields contaminated with tree sap, chemicals, wax or bugs, clean the entire windshield using steel wool (no greater than 0000 grade) in a circular motion and rinse with water. • Clean the wiper blades with isopropyl rubbing alcohol or windshield washer fluid.

WARNING
Do not use chemical solvents or strong detergents when cleaning the steering wheel or instrument panel
to avoid contamination of the airbag system.
Clean the instrument panel and cluster lens with a clean, damp, white cotton cloth, then use a clean and dry white cotton cloth to dry these areas. • Avoid cleaners or polishes that increase
the gloss of the upper portion of the instrument panel. The dull finish in this area helps protect you from undesirable windshield reflection. Be certain to wash or wipe your hands clean if you have been in contact with certain products such as insect repellent and suntan lotion in order to avoid possible damage to the interior painted surfaces.
•
• Do not use household or glass cleaners as these may damage the finish of the instrument panel, interior trim and cluster lens.
• Do not allow air fresheners and hand sanitizers to spill onto interior surfaces. If a spill occurs, wipe off immediately. Damage may not be covered by your warranty.
If a staining liquid like coffee or juice has been spilled on the instrument panel or on interior trim surfaces, clean as follows: 1. Wipe up spilled liquid using a clean,
white, cotton cloth.
Note: Do not use razor blades or other sharp objects to clean or remove decals from the inside of the heated rear window. The vehicle warranty does not cover damage caused to the heated rear window grid lines. CLEANING THE INTERIOR
WARNINGS
Do not use cleaning solvents, bleach or dye on the vehicle’s safety belts, as these actions may weaken the
belt webbing.
On vehicles equipped with seat-mounted airbags, do not use chemical solvents or strong detergents. Such products could contaminate the side airbag system and affect performance of the side airbag in a collision.
For fabric, carpets, cloth seats, safety belts and seats equipped with side airbags: • Remove dust and loose dirt with a
vacuum cleaner.
•
• Remove light stains and soil with Motorcraft Professional Strength Carpet & Upholstery Cleaner. If grease or tar is present on the material, spot-clean the area first with Motorcraft Spot and Stain Remover. In Canada, use Motorcraft Multi-Purpose Cleaner. If a ring forms on the fabric after spot cleaning, clean the entire area immediately (but do not oversaturate) or the ring will set.

• Protect from sunlight, if possible. If vehicles are stored outside, they • require regular maintenance to protect against rust and damage.
Body • Wash your vehicle thoroughly to
remove dirt, grease, oil, tar or mud from exterior surfaces, rear-wheel housing and underside of front fenders.
• Periodically wash your vehicle stored
in exposed locations. Touch-up exposed or primed metal to prevent rust.
•
• Cover chrome and stainless steel parts with a thick coat of auto wax to prevent discoloration. Re-wax as necessary when your vehicle is washed. Lubricate all hood, door and trunk lid hinges, and latches with a light grade oil.
•
• Cover interior trim to prevent fading. •
Keep all rubber parts free from oil and solvents.
Engine •
The engine oil and filter should be changed prior to storage, as used engine oil contain contaminates that may cause engine damage. Start the engine every 15 days. Run at fast idle until it reaches normal operating temperature
•
• With your foot on the brake, shift
through all the gears while the engine is running.
Note: Industrial-strength or heavy-duty cleaners in combination with brush agitation to remove brake dust and dirt, could wear away the clear coat finish over a period time. Note: Do not use hydrofluoric acid-based or high caustic-based wheel cleaners, steel wool, fuels or strong household detergents. Note: If you intend parking your vehicle for an extended period after cleaning the wheels with a wheel cleaner, drive your vehicle for a few minutes before doing so. This will reduce the risk of increased corrosion of the brake discs. Alloy wheels and wheel covers are coated with a clear coat paint finish. To maintain their condition we recommend that you: • Clean the wheels weekly using
Motorcraft Wheel and Tire Cleaner. Apply using manufacturer's instructions.
• Use a sponge to remove heavy deposits of dirt and brake dust accumulation.
• Rinse thoroughly with a strong stream of water when you have completed the cleaning process. To remove tar and grease, use Motorcraft Bug and Tar Remover.

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. Study your owner's manual 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. Four-wheel drive system (if equipped)
WARNING
Do not become overconfident in the ability of four-wheel drive vehicles. Although a four-wheel drive vehicle may accelerate better than a 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.
A vehicle equipped with four-wheel drive (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. For four-wheel drive vehicles, a spare tire of a different size other than the tire provided should never be used. A dissimilar spare tire size (other than the spare tire provided) or major dissimilar tire sized between the front and rear axles could cause the four-wheel drive system to stop functioning and default to front-wheel drive.
GENERAL INFORMATION Notice to utility vehicle and truck owners
WARNINGS
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 seat belts and children/infants must use appropriate restraints to minimize the risk of injury or ejection.
Do not become overconfident in the ability of four-wheel drive vehicles. Although a four-wheel drive vehicle may accelerate better than a 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 Sport utility vehicles and trucks can differ from some other vehicles in a few noticeable ways. Your vehicle may be:
As a result of the above dimensional differences, Sport utility vehicles 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.
•
• 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.

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 (1
½) 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
TIRE CARE 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).

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 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. Glossary of Tire Terminology *Tire label: A label showing the 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.

A. P: Indicates a tire, designated by the Tire and Rim Association, that may be used for service on cars, sport utility vehicles, minivans and light trucks. Note: If your tire size does not begin with a letter this may mean it is designated by either the European Tire and Rim Technical Organization or the Japan Tire Manufacturing Association. B. 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. C. 65: Indicates the aspect ratio which gives the tire's ratio of height to width. D. R: Indicates a radial type tire. E. 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. F. 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 manual. 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.
G. 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

J. 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. K. Maximum Load: Indicates the maximum load in kilograms and pounds that can be carried by the tire. (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. L. 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 1½ 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.

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. 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
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!
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 (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. Failure to follow the tire pressure recommendations can cause uneven treadwear patterns and adversely affect the way your vehicle handles
263
Super Duty (TFA)
Wheels and Tires
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 Inflation Pressure is the tire manufacturer's maximum permissible pressure and 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 located on
the B-pillar or the edge of the
driver's door. The cold inflation
pressure should never be set lower
than the recommended pressure
on the Safety Compliance
Certification Label or Tire Label.
When weather temperature
changes occur, tire inflation
pressures also change. A 10°F
(6°C) temperature drop can
cause a corresponding drop of 1
psi (7 kPa) in inflation pressure.
Check your tire pressures
frequently and adjust them to the
proper pressure which can be
found on the Safety Compliance
Certification Label or Tire Label.
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.
Note: If you are checking tire
pressure when the tire is hot, (for
example, driven more than 1 mile
[1.6 kilometers]), 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.
264
Super Duty (TFA)
Wheels and Tires
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 pressing 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 wheel and tire assembly information for a description. Store and maintain at 60 psi (4.15 bar). For full-size and dissimilar spare tires, see the Dissimilar spare wheel and tire assembly information for a description. Store and maintain at the higher of the front and rear inflation pressure as shown on the Safety Compliance Certification Label or Tire Label.
6. Visually inspect the tires to make sure there are no nails or other objects embedded that could poke a hole in the tire and cause an air leak. 7. Check the sidewalls to make sure there are no gouges, cuts or bulges. Tire 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 regulations. For example, during

For your safety, tires that are damaged or show signs of excessive wear should not be used because they are more likely to blow out or fail. Improper or inadequate vehicle maintenance can cause tires to wear abnormally. Inspect all your tires, including the spare, frequently, and replace them if one or more of the following conditions exist:
WARNING
Stay out of the trajectory (1) as indicated in the illustration.
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

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
WARNING
Tires degrade over time depending on many factors such as weather, storage conditions, and conditions of use (load, speed, inflation pressure) 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.

This information identifies and
Tire Wear
When the tread is worn down to
one sixteenth of an inch (2
millimeters), 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 one sixteenth of
an inch (2 millimeters).
When the tire tread wears down
to the same height as these wear
bars, the tire is worn out and must
be replaced.

WARNINGS
When inflating the tire for mounting pressures up to 20 psi (1.38 bar) greater than the maximum pressure on the tire sidewall, the following precautions must be taken to protect the person mounting the tire: 1. Make sure that you have the correct tire and wheel size. 2. Lubricate the tire bead and wheel bead seat area again. 3. Stand at a minimum of 12 feet (3.6 meters) away from the wheel and tire assembly. 4. Use both eye and ear protection. For a mounting pressure more than 20 psi (1.38 bar) 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 feet (3.6 meters) away from the wheel and tire assembly
Important: Remember to replace the wheel valve stems when the road tires are replaced on your vehicle
The two front tires or two rear tires should 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 the tire pressure monitoring system indicator is flashing, the system is malfunctioning. Your replacement tire might be incompatible with your tire pressure monitoring system, or some component of the system may be damaged. Safety Practices
WARNINGS
If your vehicle is stuck in snow, mud, or sand, do not rapidly spin the tires; spinning the tires can tear the tire and cause an explosion. A tire can explode in as little as three to five seconds.
Do not spin the wheels at over 35 mph (56 km/h). The
tires may fail and injure a passenger or bystander.
Driving habits have a great deal to do with your tire mileage and safety. *Observe posted speed limits
270
Super Duty (TFA)
Wheels and Tires
*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 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 a tire pressure monitoring system, then the settings for the system sensors need to be updated. Always perform the system reset procedure after tire rotation. If the system is not reset, it may not provide a low tire pressure warning when necessary.

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 wheel and tire assembly. A dissimilar spare wheel and tire assembly is defined as a spare wheel and tire assembly that is different in brand, size or appearance from the road tires and wheels. If you have a dissimilar spare wheel and tire 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.

E142548E166988Wheels and Tires
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. 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. 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, transfer case or 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 cables. If you need to use cables, it is recommended that steel wheels (of the same size and specifications) be used, as cables 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. Follow these guidelines when using snow tires and chains: •
If possible, avoid fully loading your vehicle
• Use only SAE Class S chains. •
Install chains securely, verifying that the chains do not touch any wiring, brake lines or fuel lines.
• Drive cautiously. If you hear the chains rub or bang against your vehicle, stop and retighten the chains. If this does not work, remove the chains to prevent damage to your vehicle.
• Remove the tire chains when they are
no longer needed. Do not use tire chains on dry roads.
If you have any questions regarding snow chains or cables, please contact your authorized dealer. TIRE PRESSURE MONITORING SYSTEM
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.
273
Super Duty (TFA)
Wheels and Tires
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.
Super Duty (TFA)
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 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,
