Instrument Cluster Diesel Exhaust Fluid (DEF) (If Equipped) WARNING Do not drain the fuel and water separator while the engine is running. Fuel may ignite if the separator is drained while the engine is running or the vehicle is moving. Note: Do not drain the fuel and water separator while the engine is running. Air will enter into the fuel system causing the engine not to operate properly. With the key in the on position, lights when the DEF is E163176 contaminated or low. See Selective Catalytic Reduction System (page 21). Glow Plug Pre-Heat With the key in the on position, lights when the glow plug heat is necessary as a starting aid. Wait until the light goes off before starting. See Starting a Diesel Engine (page 10). After you start the engine, the light should turn off. When the engine is cold, the light should always light for a short period. Water In Fuel During refueling, it is possible for you to pump water-contaminated diesel fuel into your fuel tank. Your vehicle's fuel system is equipped with a fuel filter and water separator to remove water from the fuel. The water in fuel indicator lights when the fuel and water separator has a significant quantity of water in it and requires immediate draining. If the water in fuel lights when the engine is running, stop your vehicle as soon as safely possible, shut off the engine, then drain the fuel and water separator. See Fuel Quality (page 15). Allowing water to stay in the fuel system, after the water in fuel indicator lights, could result in extensive damage or failure of the fuel injection system. 9 Super Duty (TFA) , enUSA
