Fuel and Refueling Your vehicle's message center will display a series of messages regarding the amount of DEF available. A systems check will display messages indicating the amount of DEF available (OK or under 1⁄2 full) or will produce a warning message that displays the mileage (kilometers) remaining as the fluid in the DEF tank nears empty. For more information on warning messages, see the Information Displays chapter of your Owner's Manual. As the DEF level nears empty, the DEF warning symbol will be displayed and chimes will sound with the messages starting at 500 miles (805 km) remaining before DEF is depleted. The warning symbol and messages will continue until the DEF tank is refilled. Continued driving without refilling 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 vehicle restart. Prior to this occurring a message will appear in the message center. • Further vehicle operation without refilling your DEF tank will cause the engine to enter an idle-only condition. This will only occur upon vehicle refueling or extended idle and will be indicated by a message in the message center indicating required actions to resume normal operation. It is required to add a minimum of 0.5 gallons (1.9L) of DEF to the tank to exit the idle-only condition, but the vehicle will still be in the speed limiting mode until the tank is refilled completely. For either vehicle speed limiting or idle-only condition, normal vehicle operation will resume when the DEF tank is refilled. Note: When filling the DEF tank from empty, there may be a short delay before detecting the increased level of DEF. This must occur before full power is returned. 20 2013 Diesel (67l) Supplement, 1st Printing USA (fus)
