Fuel and Refueling • Adding certain accessories to your vehicle (for example bug deflectors, rollbars/light bars, running boards, ski 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. Close windows for high speed driving. • Do not turn off the ignition while your vehicle is moving, especially at high speeds. Have the items listed in scheduled maintenance information performed according to the specified schedule. • • • • The scheduled maintenance items listed in scheduled maintenance information are essential to the life and performance of your vehicle and to its emissions system. If you use parts other than Ford, Motorcraft or Ford-authorized parts for maintenance replacements, or for service of components affecting emission control, such non-Ford parts should be the equivalent to genuine Ford Motor Company parts in performance and durability. Illumination of the service engine soon indicator, charging system warning light or the temperature warning light, fluid leaks, strange odors, smoke or loss of engine power could indicate that the emission control system is not working properly. An improperly operating or damaged exhaust system may allow exhaust to enter the vehicle. Have a damaged or improperly operating exhaust system inspected and repaired immediately. Do not make any unauthorized changes to your vehicle or engine. By law, vehicle owners and anyone who manufactures, repairs, services, sells, leases, trades vehicles, or supervises a fleet of vehicles are not permitted to intentionally remove an emission control device or prevent it from working.

Exhaust leaks may result in entry of harmful and potentially lethal fumes into the passenger compartment. If you smell exhaust fumes inside your vehicle, have your dealer inspect your vehicle immediately. Do not drive if you smell exhaust fumes. Your vehicle is equipped with various emission control components and a catalytic converter that will enable your vehicle to comply with applicable exhaust emission standards. To make sure that the catalytic converter and other emission control components continue to work properly: • • Use only the specified fuel listed. Avoid running out of fuel. 143 Super Duty (), enUSA
