2011 FORD SUPER DUTY ECO mode

As the DEF level nears empty, the
DEF warning symbol will be
displayed and chimes will sound
with the messages starting at
300 miles (483 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 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 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.
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.

If fuses burn out
Burned-out or blown fuses usually indicate an electrical short-circuit,
although a fuse may occasionally burn out from vibration. Insert a second
fuse. If this fuse immediately burns out and you cannot locate the cause,
return your vehicle to your dealer for a circuit check.
WARNING:Replacement fuses and circuit breakers must always
be the same rating as the original equipment shown. Never
replace a fuse or circuit breaker with one of a higher rating. Higher
rated fuses or circuit breakers could allow circuit overloading in the
event of a circuit malfunction, resulting in severe vehicle damage or
personal injury due to fire.
Refer to theOwner’s Guidefor replacement of fuses.
Selective catalytic reduction (SCR) system speed limit and
Idle-only modes
If the vehicle’s speed is limited or in an idle-only mode, the SCR system
may be limiting the vehicle’s functions due to low or contaminated diesel
exhaust fluid (DEF). Check the DEF. SeeSelective catalytic reduction
(SCR) systemin theMaintenance and Specificationschapter for more
information.

Intelligent Oil Life Monitor™
Your diesel engine is equipped with an Intelligent Oil Life Monitor™ that
calculates the proper engine oil change service interval based on vehicle
use. The following table is intended to provide examples of vehicle use
and its impact on engine oil change interval; it is provided as a guideline
only. Actual engine oil change intervals will depend on several factors
and will generally decrease with severity of use.
