DRIVE TO CLEAN EXHAUST SYSTEM (diesel engine only) —
Displayed when the Diesel Particulate Filter (DPF) is full of particles
(exhaust soot) and the vehicle is not being operated in a manner to
allow normal cleaning. This message will stay on until the exhaust filter
cleaning has begun, at which time the CLEANING EXHAUST FILTER
message will be displayed. It is recommended the vehicle operator drive
the vehicle above 30 mph (48 km/h) until the CLEANING EXHAUST
FILTER message turns off. This message is NORMAL. Refer to your
diesel supplement for more information.
Note: If this message is ignored, your vehicle will continue to fill the
Diesel Particulate Filter (DPF) with particles (exhaust soot). If cleaning
is not permitted, the light will illuminate and engine power may be
limited. If the vehicle is still not operated in a manner to allow cleaning,
the service engine soon light will illuminate and engine power will
be further limited. Dealer service will then be required to restore your
vehicle to full-power operation.
STOP SAFELY NOW (diesel engine only) — Displayed and a chime
sounds when the vehicle exhaust system temperature exceeds intended
operating range. If this warning occurs, engine power is reduced and the
engine will shut down when the vehicle speed is below 3 mph (5 km/h).
Stop the vehicle as soon as safely possible and contact your
authorized dealer. Depending on the severity of the over-temperature
condition, the vehicle may not restart after cycling the ignition off. If the
vehicle restarts, there may be limited power. If the exhaust
over-temperature condition reoccurs, the message center will display
STOP SAFELY NOW, the chime will sound, and engine power will be
reduced again and shut down below 3 mph (5 km/h). Refer to your
diesel supplement for more information.
ENGINE OIL DILUTED (diesel engine only) — Displays once the

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. Instrument Cluster

CDs with homemade paper
(adhesive) labels should not be
inserted into the CD player as
the label may peel and cause the
CD to become jammed. It is

contact your authorized dealer for further information.
Audio system warranty and service
Refer to the Warranty Guide/Customer Information Guide for audio
system warranty information. If service is necessary, see your dealer or

MP3 track and folder structure
Your MP3 system recognizes MP3 individual tracks and folder structure
as follows:
• There are two different modes for MP3 disc playback: MP3 track mode
(system default) and MP3 folder mode. For more information on track
and folder mode, refer to Sample MP3 structure in the following
section.
• MP3 track mode ignores any folder structure on the MP3 disc. The
player numbers each MP3 track on the disc (noted by the .mp3 file
extension) from T001 to a maximum of T255.
Note: The maximum number of playable MP3 files may be less
depending on the structure of the CD and exact model of radio
present.
• MP3 folder mode represents a folder structure consisting of one level
of folders. The CD player numbers all MP3 tracks on the disc (noted
by the .mp3 file extension) and all folders containing MP3 files, from
F001 (folder) T001 (track) to F253 T255.
• Creating discs with only one level of folders will help with navigation
through the disc files. Entertainment Systems

• Terrain: Hills, mountains, tall buildings, bridges, tunnels, freeway
overpasses, parking garages, dense tree foliage and thunderstorms can
interfere with your reception.
• Station overload: When you pass a ground based broadcast repeating
tower, a stronger signal may overtake a weaker one and result in an
audio mute.
Unlike AM/FM audible static, you will hear an audio mute when there is
a satellite radio signal interference. Your radio display may display NO
SIGNAL to indicate the interference.
