TOWING A TRAILER WARNINGS Do not exceed the GVWR or the GAWR specified on the certification label. Towing trailers beyond the maximum recommended gross trailer weight exceeds the limit of the vehicle and could result in engine damage, transmission damage, structural damage, loss of vehicle control, vehicle rollover and personal injury. Your vehicle may have electrical items, such as fuses or relays, related to towing. See Fuses (page 161). Your vehicle's load capacity designation is by weight, not by volume, so you cannot necessarily use all available space when loading a vehicle. Towing a trailer places an extra load on your vehicle's engine, transmission, axle, brakes, tires and suspension. Inspect these components periodically during, and after, any towing operation. Load Placement To help minimize how trailer movement affects your vehicle when driving: • Load the heaviest items closest to the trailer floor. • Load the heaviest items centered between the left and right side trailer tires. • Load the heaviest items above the trailer axles or just slightly forward toward the trailer tongue. Do not allow the final trailer tongue weight to go above or below 10-15% of the loaded trailer weight. When driving with a trailer or payload, a slight takeoff vibration or shudder may be present due to the increased payload weight. Additional information regarding proper trailer loading and setting your vehicle up for towing is located in another chapter of this manual. See Load Limit (page 135). You can also find information in the RV & Trailer Towing Guide available at your authorized dealer, or online.

ESSENTIAL TOWING CHECKS See Load limits in the Load Carrying chapter for load specification terms found on the tire label and Safety Compliance label and instructions on calculating your vehicle's load. Remember to account for the trailer tongue weight as part of your vehicle load when calculating the total vehicle weight. Hitches Do not use a hitch that either clamps onto the bumper or attaches to the axle. You must distribute the load in your trailer so that 10-15% of the total weight of the trailer is on the tongue. Safety Chains Note: Do not attach safety chains to the bumper. Always connect the safety chains to the frame or hook retainers of your vehicle hitch. To connect the safety chains, cross the chains under the trailer tongue and allow enough slack for turning tight corners. Do not allow the chains to drag on the ground. Trailer Brakes WARNING Do not connect a trailer's hydraulic brake system directly to your vehicle's brake system. Your vehicle may not have enough braking power and your chances of having a collision greatly increase. Electric brakes and manual, automatic or surge-type trailer brakes are safe if you install them properly and adjust them to the manufacturer's specifications. The trailer brakes must meet local and federal regulations. The rating for the tow vehicle's braking system operation is at the gross vehicle weight rating, not the gross combined weight rating. Trailer Lamps WARNING Never connect any trailer lamp wiring to the vehicle's tail lamp wiring; this may damage the electrical system resulting in fire. Contact your authorized dealer as soon as possible for assistance in proper trailer tow wiring installation. Additional electrical equipment may be required. Trailer lamps are required on most towed vehicles. Make sure all running lights, brake lights, turn signals and hazard lights are working. Before Towing a Trailer Practice turning, stopping and backing up to get the feel of your vehicle-trailer combination before starting on a trip. When turning, make wider turns so the trailer wheels clear curbs and other obstacles. When Towing a Trailer • Check your hitch, electrical connections and trailer wheel lug nuts thoroughly after you have traveled 50 miles (80 kilometers). • When stopped in congested or heavy traffic during hot weather, place the gearshift in position P or position N to aid engine and transmission cooling and to help air conditioning performance. • Turn off the speed control with heavy loads or in hilly terrain. The speed control may turn off automatically when you are towing on long, steep grades. 140 F-650/750 (TBC) , enUSA, First Printing Towing

• Shift to a lower gear when driving down a long or steep hill. Do not apply the brakes continuously, as they may overheat and become less effective. • If your transmission is equipped with the Tow/Haul feature, use this feature when towing. This provides engine braking and helps eliminate excessive transmission shifting for optimum fuel economy and transmission cooling. • Allow more distance for stopping with a trailer attached. Anticipate stops and brake gradually. FIFTH WHEEL OPERATION WARNINGS Failure to follow the fifth wheel manufacturer ’s instructions for hooking and unhooking as well as sliding the fifth wheel could result in an accident, personal injury or death. When the tractor and trailer are parked unattended, the trailer brake hand control should never be used to apply the brake, since air may leak from the system, allowing vehicle movement, resulting in possible property damage, personal injury or death. Before hook-up, make sure: • The fifth wheel jaws are fully open. • The fifth wheel is fully tilted back to prevent body damage when the tractor is backed under a trailer. • You block the trailer wheels and adjust and apply the trailer spring brakes. Never chase a trailer. • The brake hoses and light cords are clear of the fifth wheel. Hook-up 1. Back the tractor squarely under the trailer, engaging the fifth-wheel jaws on the kingpin. Always back up slowly; make sure the trailer is neither too high nor too low. Avoid backing under the trailer from an angle. 2. Connect the service and emergency brake hoses and trailer light connector. 3. Inspect the jaws of the fifth wheel to be sure they have fully closed on the trailer kingpin and the trailer plate is resting securely on the fifth wheel. 4. Make sure the coupler release lever is in the locked position. 5. Charge the trailer brake system. Set the trailer brakes, with either the hand valve or tractor protection valve. Pull against the trailer for an extra check of proper hook-up. Do not pull hard enough to damage or strain the equipment. 6. Set the tractor parking brakes and fully raise the trailer landing gear. 7. Check the operation of all trailer lights and correct any lights that may be faulty. Un-hook 1. Try to keep the tractor and trailer in a straight line. 2. Apply the parking brakes. 3. Lower the trailer landing gear, making sure it is on solid, level ground. The weight of the trailer is to be on the landing gear. 4. Block the trailer wheels. 5. Disconnect the brake hoses and light cords. Be sure hoses and cords are clear. 6. Pull coupler release lever to disengage the fifth wheel jaws. 141 F-650/750 (TBC) , enUSA, First Printing Towing

BREAKING-IN You need to break in new tires for approximately 300 mi (480 km). During this time, your vehicle may exhibit some unusual driving characteristics. Avoid driving too fast during the first 1,000 mi (1,600 km) . Vary your speed frequently and change up through the gears early. Do not labor the engine. Drive your new vehicle at least 500 mi (800 km) before towing a trailer. Make sure you use the specified engine oil. See Capacities and Specifications (page 258). Do not add friction modifier compounds or special break-in oils during the first few thousand miles (kilometers) of operation. These additives may prevent piston ring seating. GENERAL DRIVING POINTS General Information • Accelerate smoothly and evenly. Rapid acceleration increases fuel consumption without increasing engine performance. • When approaching a hill, press the accelerator smoothly to start the incline at full power, and then shift down as needed to maintain vehicle speed. • When going down a hill, or long steep grades, prevent overspeeding of the engine. Normally, choose the same gear to descend the hill that you use to ascend the hill. The engine governor has no control over engine speed when it is being pushed by a loaded vehicle. • Do not operate in a gear that permits an engine speed more than the maximum governed speed or high-idle RPM (no load). • Always shift to a lower gear at high altitudes to prevent engine smoking. Backing Up WARNINGS All vehicles have blind spots. To reduce the risk of severe injury or property damage, never move your vehicle to the side or rear or change lanes without being sure your way is clear on both sides and to your rear. To reduce the risk of the possibility of personal injury while backing up the vehicle, always be sure your vehicle ’s path is clear. Before backing up your vehicle, be sure you can do so safely. If anything behind the cab limits your view, do not rely on mirrors alone to make sure that your intended path is clear. If other people are in the vicinity, have someone standing well behind your vehicle and outside of your intended path (visible through an exterior mirror) guide you as you back up. Although OSHA or some governmental regulations may require the use of an electrical or mechanical back up alarm to warn bystanders, such an alarm does not guarantee that the intended path is clear. When in doubt, get out of your vehicle and visually check the intended path is clear. Back up slowly as to allow others time to move, if necessary. If you install an electrical back up alarm, connect it to the backup lamp circuit. 143 F-650/750 (TBC) , enUSA, First Printing Driving Hints

Parking WARNING When parking your vehicle, do not leave the transmission in gear; if the key is in the on position and the vehicle rolls, the engine could start. Failure to follow these instructions could result in an unattended vehicle moving, possibly causing personal injury or property damage. Always use the parking brake. When parking on a grade, block the wheels and turn the front wheels to one side so that if your vehicle rolls, the front tires act against the curb to stop your vehicle. The front wheels are more effective at stopping a rolling vehicle than the rear wheels. ECONOMICAL DRIVING Your fuel economy is affected by several things, such as how you drive, the conditions you drive under, and how you maintain your vehicle. You may improve your fuel economy by keeping these things in mind: • Accelerate and slow down in a smooth, moderate fashion. • Drive at steady speeds without stopping. • Anticipate stops; slowing down may eliminate the need to stop. • Close the windows for high-speed driving. • Drive at reasonable speeds (traveling at 55 mph [88 km/h] uses 15% less fuel than traveling at 65 mph [105 km/h]). • Keep the tires properly inflated and use only the recommended size. • Use the recommended engine oil. • Perform all regularly scheduled maintenance. Avoid these actions; they reduce your fuel economy: • Sudden accelerations or hard accelerations. • Warm up your vehicle on cold mornings. • Use the air conditioner or front defroster. • Use the speed control in hilly terrain. • Rest your foot on the brake pedal while driving. • Carry unnecessary weight (approximately 1 mpg [0.4 km/L] is lost for every 400 lb [180 kilogram] of weight carried). • Driving with the wheels out of alignment. Conditions • Adding certain accessories to your vehicle (for example bug deflectors, rollbars, light bars, running boards, ski racks or luggage racks) may reduce fuel economy. • Using fuel blended with alcohol may lower fuel economy. • Fuel economy may decrease with lower temperatures during the first 8– 10 miles (12 –16 kilometers) of driving. • Driving on flat terrain offers improved fuel economy as compared to driving on hilly terrain. • Transmissions give their best fuel economy when operated in the top cruise gear and with steady pressure on the gas pedal. 144 F-650/750 (TBC) , enUSA, First Printing Driving Hints

COLD WEATHER PRECAUTIONS Note: Idling in cold weather does not heat the engine to its normal operating temperature. Long periods of idling, especially in cold weather, can cause a buildup of deposits which can cause engine damage. Changing to a lighter grade engine oil also makes starting easier under these conditions. Refer to Engine oil specifications. See Capacities and Specifications (page 258). Diesel fuel is adjusted seasonally for cold temperatures. Diesel fuel which has not been properly formulated for the ambient conditions may gel which can clog the fuel filters. One indication that the fuel filter(s) may be clogged is if the engine starts, stalls after a short time, and then does not restart. If you have been using biodiesel, you may need to use a fuel with lower biodiesel content, try another brand, or discontinue using biodiesel. Do not use alcohol based additives to correct fuel gelling. This may result in damage to the fuel injectors and system. Use the proper anti-gel and performance improvement product. See Capacities and Specifications (page 258). Your vehicle is equipped with a fuel and water separator that recirculates fuel from the engine to help prevent fuel filter clogging. To avoid engine fuel starvation during cold weather operation of 32°F (0°C) or below, we recommended that the fuel level in your tank should not drop below 1⁄4 full. This helps prevent air from entering the fuel system and stalling the engine. Your vehicle is equipped with a selective catalyst reduction system that uses Diesel Exhaust Fluid (DEF) to operate properly. You need to replenish your vehicle ’s DEF at certain intervals. When filling your vehicle ’s DEF tank in cold weather, you must take special care to prevent damage to the tank. See Selective Catalytic Reduction System (page 95). In cold weather below 32°F (0°C), the engine may slowly increase to a higher idle speed if left idling in park (P) or neutral (N). If you operate your vehicle in a heavy snowstorm or blowing snow conditions, snow and ice can clog the engine air induction. If this occurs, the engine may experience a significant reduction in power output. At the earliest opportunity, clear all the snow or ice away from inside the air filter assembly. Remove the air cleaner cover and the pleated paper filter, leaving the foam filter in and remove any snow or ice. Make sure you install the foam filter correctly in place. Remove any debris, snow or ice on the foam filter by brushing the surface with soft brush. Once you have cleared all of the debris, reinstall the air filter and assembly. Do not use water, solvents, or a hard brush for cleaning the foam filter. WARNING To reduce the risk of vehicle damage and/or personal burn injuries do not start your engine with the air filter removed and do not remove it while the engine is running. 145 F-650/750 (TBC) , enUSA, First Printing Driving Hints

In order to operate the engine in temperatures of 32°F (0°C) or lower, read the following instructions: • Make sure that the batteries are of sufficient size and are fully charged. Check other electrical components to make sure they are in optimum condition • Use the proper coolant solution at the concentration recommended protecting the engine against damage from freezing • Try to keep the fuel tank full as much as possible at the end of operation to prevent condensation in the fuel system • Make sure you use proper cold weather engine oil and that it is at its proper level. Also, if necessary, make sure to follow the engine oil and filter change schedule found under the Special operating conditions section listed in the scheduled maintenance information • At temperatures of -9°F (-23°C) or below, it is recommended that you use an engine block heater to improve cold engine starting • If operating in arctic temperatures of -20°F (-29°C) or lower, consult your truck dealer for information about special cold weather equipment and precautions The following cold weather idling guidelines are recommended: • You can use Motorcraft® cetane improvers or non-alcohol-based cetane improvers from a reputable manufacturer as needed. • Maintain the engine cooling system properly. • Avoid shutting the engine down after an extensive idling period. Drive your vehicle for several miles with the engine at normal operating temperatures under a moderate load. • Consider using an engine block heater. • For extended idle times use an approved idle speed increase device. Winter Operating Tips for Arctic Operation -20°F (-29°C) and Below The following information is a guideline only and is not to be the only source of possible solutions in resolving extreme cold temperature issues. Starting Aids WARNING Do not use starting fluid, such as ether, in the air intake system (see air filter decal). Such fluid could cause immediate explosive damage to the engine and possible personal injury. The use of the factory engine block heater assists in engine starting in extreme cold ambient temperatures. See Engine Block Heater (page 88). Idle Control Your vehicle may have a factory option for a stationary elevated idle control through dash-mounted upfitter switches that allows the operator to elevate the idle rpm for extended idle periods, as well as aftermarket equipment such as PTO operation. You must configure this feature even if ordered from the factory. See your authorized dealer for required upfitting. 146 F-650/750 (TBC) , enUSA, First Printing Driving Hints

Operation in Snow and Rain Vehicle operation in heavy snowfall or extreme rain conditions may feed excessive amounts of snow or water into the air intake system. This could plug the air filter with snow and may cause the engine to lose power and possibly shut down. We recommend the following actions after operating your vehicle up to 199 mi (320 km) in snowfall or extreme rain: • Snow: At the earliest opportunity, open the hood and clear all the snow and ice from the air filter housing inlet (do not remove the foam filter) and reset the air filter restriction gauge. Note: Removal of the foam filter degrades your vehicle performance during snow and hot weather conditions. • Extreme rain: The air filter dries after about 15– 30 minutes at highway speeds. At the earliest opportunity, open the hood and reset the air filter restriction gauge. DRIVING THROUGH WATER WARNING Do not drive through flowing or deep water as you may lose control of your vehicle. Note: Driving through standing water can cause vehicle damage. Note: Engine damage can occur if water enters the air filter. Before driving through standing water, check the depth. Never drive through water that is higher than the bottom of the wheel hubs. When driving through standing water, drive very slowly and do not stop your vehicle. Your brake performance and traction may be limited. After driving through water and as soon as it is safe to do so: • Lightly press the brake pedal to dry the brakes and to check that they work. • Check that the horn works. • Check that the exterior lights work. • Turn the steering wheel to check that the steering power assist works. Operation in Standing Water Ingestion of water into the diesel engine can result in immediate and severe damage to the engine. If driving through water, slow down to avoid splashing water into the intake. If the engine stalls, and you suspect ingestion of water into the engine, do not try to restart the engine. Consult your dealer for service immediately. Your fuel tank vents to the atmosphere by valves on top of the tank and through the fuel cap. If water reaches the top of the tank, the valves may pull water into the fuel tank. Water in the fuel can cause performance issues and damage the fuel injection system. 147 F-650/750 (TBC) , enUSA, First Printing Driving HintsE176913
