Starting and Stopping the Engine 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 200 miles (320 kilometers) 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. 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. SWITCHING OFF THE ENGINE Turn the ignition to the off position. To prolong engine life (especially after extended high speed, high ambient temperature, or high GVW/GCW operation, such as heavy loads or heavy trailers), it is recommended that a hot engine be idled for 3-5 minutes. This allows the turbocharged engine to cool down. For more information on GVW/GCW, see the Load Carrying chapter in your Owner 's Manual. 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. ENGINE IDLE SHUTDOWN Your vehicle may be equipped with an engine idle shutdown system. This system automatically shuts down your engine when it has been idling in P (Park) or N (Neutral) for five minutes (parking brake set) or 15 minutes (parking brake not set). When the engine idle shutdown process has started: • A chime sounds and the information display will show ENGINE TURNS OFF IN 30 (seconds) and start counting down You can restart the five or 15-minute timer by changing the position of the accelerator pedal, brake pedal or the park brake within the final 30 seconds When the timer reaches zero, the engine shuts down and this message will appear in your information display ENGINE TURNED OFF Refer to Air filter and restriction gauge in the Maintenance chapter for more information. See Changing the Engine Air Filter (page 49). 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. • • 12 Super Duty (TFA)
