Maintenance and Specifications After installation of the new filter element, reset the gauge by pressing the reset button on top of the gauge. Note: Vehicle operation in heavy snowfall or extreme rain conditions may feed excessive amounts of snow/water into the air intake system. This could plug/soak the air filter with snow and may cause the engine to lose power and possibly shut down. The following actions are recommend after operating the vehicle up to 200 miles (320 km) in heavy 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. • Extreme rain: The air filter will dry after about 15-30 minutes at highway speeds. At the earliest opportunity, open the hood and reset the air filter restriction gauge. Air filter replacement: When replacing the air filter element, use the Motorcraft air filter element listed in Motorcraft part numbers later in this chapter. 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. 52 2011 Diesel (eco) Supplement, 5th Printing USA (fus)
