Instrument Cluster ENGINE IDLED - SEE OWNER'S MANUAL EXHAUST FLUID SYSTEM FAULT (diesel engine only) - Displayed when the SCR system detects a fault. The engine will eventually enter into an idle-only mode. Press OK to override the idle mode. Refer to your diesel supplement for more information. Contact your authorized dealer as soon as possible. FUEL FILTER CHANGE REQUIRED (diesel engine only) - Displayed when a fuel filter change is required. Refer to the scheduled maintenance information. LOW FUEL PRESSURE (diesel engine only) - If this message appears during a cold start or during cold operation 32°F (0°C) up to 10 minutes after the initial cold start; monitor the message center and if it disappears and does not re-appear after the engine has fully warmed up, the low fuel pressure message is most likely caused by waxed or gelled fuel. To prevent this, use an anti-gel additive. Refer to your diesel supplement for more information. The customer warranty may be void from using additives that do not meet or exceed Ford specifications. If the low fuel pressure message persistently appears after re-fueling during the cold start and cold operation conditions defined previously and then disappear when the engine has fully warmed up, consider different fuel sources. • Low Fuel Operation: If the message appears when the vehicle is warm and during low fuel tank level operation, i.e. the tank level is at or very near empty, refuel the vehicle and operate the vehicle. If the message reappears after fueling, see below. If the message does not come back, the low fuel pressure condition was due to low fuel levels in the fuel tank. • Normal Operation: If the message appears during normal operation when the vehicle / engine is fully warm, and fuel level is not low, the fuel filters must be changed regardless of the maintenance schedule interval. If replacement of the fuel filter does not remedy the low fuel pressure message during normal operation as defined above, please take the vehicle to your authorized dealer. REDUCED ENGINE POWER (diesel engine only) - Displayed approximately two hours after the DRIVE TO CLEAN EXHAUST SYSTEM message has displayed and the vehicle operator has not driven the vehicle above 30 mph (48 km/h) for at least 20 minutes to clean the DPF. At this point the vehicle must be serviced by an authorized dealer. This message is normal. Refer to your diesel supplement for more information. 53 2012 F-250/350/450/550 (f23) Owners Guide, 4th Printing USA (fus)
