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 toInflating Your Tiresin the
Tires, Wheels and Loadingchapter.
TIRE PRESSURE MONITOR FAULT— Displayed when the Tire
Pressure Monitoring System is malfunctioning. If the warning stays on or
continues to come on, have the system inspected by your authorized
dealer.

Filling the tank
The advertised fuel capacity of the fuel tank on your vehicle is equal to
the rated refill capacity of the fuel tank as listed in theMaintenance
product specifications and capacitiessection of this chapter.
The advertised capacity is the amount of the indicated capacity and the
empty reserve combined. Indicated capacity is the difference in the
amount of fuel in a full tank and a tank when the fuel gauge indicates
empty. Empty reserve is the small amount of fuel remaining in the fuel
tank after the fuel gauge indicates empty.
The amount of usable fuel in the empty reserve varies and should
not be relied upon to increase driving range. When refueling your
vehicle after the fuel gauge indicates empty, you might not be
able to refuel the full amount of the advertised capacity of the
fuel tank due to the empty reserve still present in the tank.
For consistent results when filling the fuel tank:
•Turn the engine/ignition switch to the off position prior to refueling,
an error in the reading will result if the engine is left running.
•Use the same filling rate setting (low — medium — high) each time
the tank is filled.
•Allow no more than two automatic click-offs when filling.
•Always use fuel with the recommended octane rating.
•Use a known quality gasoline, preferably a national brand.
•Have the vehicle loading and distribution the same every time.
Your results will be most accurate if your filling method is consistent.
Calculating fuel economy
1. Fill the fuel tank completely and record the initial odometer reading
(in miles or kilometers).
2. Each time you fill the tank, record the amount of fuel added (in
gallons or liters).
3. After at least three to five tank fill-ups, fill the fuel tank and record
the current odometer reading.
4. Subtract your initial odometer reading from the current odometer
reading.
5. Follow one of the simple calculations in order to determine fuel
economy:
Calculation 1:Divide total miles traveled by total gallons used.
