Maintenance and Specifications To prevent overfilling of the DEF tank when filling with a bottle, Ford recommends using Motorcraft௡ DEF. Additionally, if the message center indicates EXHAUST FLUID UNDER 1/2 FULL, you should only add a MAXIMUM of 2 gallons (6.7L) of DEF to the tank to prevent freeze damage due to overfilling. If the message center indicates EXHAUST FLUID LEVEL OK, do not add DEF. Contaminated DEF SCR systems are sensitive to contamination of the DEF. USE ONLY API or ISO 22241 CERTIFIED DIESEL EXHAUST FLUID. If the system becomes contaminated, the DEF light will illuminate and contaminated exhaust fluid messages will appear in the message center. Continued driving without replacing DEF will result in the following actions as required by the California Air Resources Board (CARB) and /or U.S. Environmental Protection Agency (EPA): • Within a certain number of miles (kilometers) to empty, speed will be limited upon restart. Prior to this occurring a message will appear in the message center. • Further vehicle operation without replacing contaminated DEF will cause the engine to enter an idle-only condition. This will only occur upon vehicle refueling and will be indicated by a message in the message center indicating required actions to resume normal operation. For either vehicle speed limiting or idle-only condition, normal vehicle operation will resume when the contaminated system is repaired. To service a contaminated SCR system, see your authorized dealer. DEF guidelines and information • Use only DEF that carries the trademark: American Petroleum Institute (API) certified DEF or ISO 22241. • Do not put DEF in the diesel fuel tank. • Do not overfill the DEF tank. • Do not re-use the DEF container or nozzle once it is emptied. • Avoid spilling DEF on painted surfaces, carpeting or plastic components. Immediately wipe away any DEF that has spilled with a damp cloth and water. If it has already crystallized, use warm water and a sponge. 35 2011 Diesel (eco) Supplement, 5th Printing USA (fus)
