FORD 2015 Mustang - Manual (Page 133)

If the fuel fill inlet was not properly closed,
a Check Fuel Fill Inlet message may
appear on the instrument cluster.
At the next opportunity, do the following:
1. Stop your vehicle as soon as safely
possible and shift the transmission into
park (P).
2. Open the fuel filler door and remove
any visible debris from the fuel fill
opening.
3. Insert either the fuel fill nozzle or the
fuel fill funnel provided with the vehicle
several times to allow the inlet to close
properly. This will dislodge any debris
preventing the inlet from sealing.
If this action corrects the problem, the
message may not reset immediately. It
may take several driving cycles for the
message to turn off. A driving cycle
consists of an engine start-up (after 4 or
more hours with the engine off) followed
by city or highway driving. Continuing to
drive with the message on may cause the
service engine soon lamp to turn on as
well.
FUEL CONSUMPTION
Your fuel tank's advertised capacity
includes the fuel indicated by your gauge
plus an empty reserve of fuel that remains
after the fuel gauge indicates empty. See
Capacities and Specifications (page
267).
• The empty reserve makes sure that you
do not run of out fuel until after the
gauge indicates empty.
• Due to the empty reserve, you may not
be able to refuel the full amount of the
advertised capacity of the fuel tank
even when the fuel gauge reads empty.
Note: The amount of fuel in the empty
reserve varies and should not be relied upon
to increase driving range.
Filling the Tank
For consistent results when refueling:
•
Always switch the ignition off before
refueling. If you leave the engine
running, you will get an inaccurate
reading.
• Use the same fill rate
(low-medium-high) each time you fill
the tank.
• Allow no more than two automatic
shut-offs when refueling.
Results are most accurate when the filling
method is consistent.
Calculating Fuel Economy
Do not measure fuel economy during the
first 1000 mi (1,600 km) of driving (this is
your engine’s break-in period). A more
accurate measurement is obtained after
2000 mi (3,000 km) to 3000 mi
(5,000 km). Also, fuel expense, frequency
of fill ups or fuel gauge readings are not
accurate ways to measure fuel economy.
1. Fill the fuel tank completely and record
the initial odometer reading.
2. Each time you fill the fuel tank, record
the amount of fuel added.
3. After at least three fill ups, fill the fuel
tank and record the current odometer
reading.
4. Subtract your initial odometer reading
from the current odometer reading.
5. Calculate fuel economy by dividing
miles traveled by gallons used (For
Metric: Multiply liters used by 100, then
divide by kilometers traveled).
