FORD 2011 F-550 v.2 - Manual (Page 54)

SPEED LIMITED TO XX MPH UPON RESTART EXHAUST FLUID
EMPTY (diesel engine only) — Displayed when the remaining diesel
exhaust fluid level is depleted. Speed will be limited upon restart. The
diesel exhaust fluid must be replenished to resume normal operation of
the vehicle. Refer to your diesel supplement for more 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.
WATER IN FUEL DRAIN FILTER SEE MANUAL (if equipped) —
Displayed when the water separator has reached a predetermined
capacity and needs to be drained. Refer to your diesel supplement for
more information.
LOW TIRE PRESSURE — Displayed when one or more tires on your
vehicle have low tire pressure. Refer to Inflating Your Tires in the
Tires, Wheels and Loading chapter.
