Ford Diesel 2012 Supplement Manual page 27

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
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 Message center section in the
Instrument Cluster chapter of your Owner's Guide.
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.
