FUEL CONSUMPTION
Empty reserve is the amount of fuel
remaining in the 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.
•
The usable capacity of the fuel tank is
the amount of fuel that can be added
into the tank after the gauge indicates
empty
• The advertised capacity is the total fuel
tank size. See Capacities and
Specifications (page 292). It is the
combined usable capacity plus the
empty reserve.
• 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.
Filling the Tank
For consistent results when filling the fuel
tank:
• Turn the ignition off before fueling; an
inaccurate reading results if the engine
is left running.
• Use the same fill rate
(low-medium-high) each time the tank
is filled.
• Allow no more than two automatic
click-offs when filling.
Results are most accurate when the filling
method is consistent. Calculating Fuel Economy
Do not measure fuel economy during the
first 1000 miles (1600 kilometers) of
driving (this is your engine
’s break-in
period); a more accurate measurement is
obtained after 2000 miles - 3000 miles
(3200 kilometers - 4800 kilometers). 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 tank, record the amount of fuel added.
3. After at least 3 to 5 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. Calculate fuel economy by dividing miles traveled by gallons used (For
Metric: Multiply liters used by 100, then
divide by kilometers traveled).
Keep a record for at least 1 month and
record the type of driving (city or highway).
This provides an accurate estimate of the
vehicle ’s fuel economy under current
driving conditions. Additionally, keeping
records during summer and winter show
how temperature impacts fuel economy.
In general, lower temperatures mean lower
fuel economy.
Conditions
• Heavily loading a vehicle or towing a
trailer may reduce fuel economy at any
speed.
• Carrying unnecessary weight may
reduce fuel economy (approximately
1 mpg [0.4 km/L] is lost for every 400
pounds [180 kilograms] of weight
carried).

WARNINGS
When doing this procedure, you will
be taking the vehicle out of park
which means the vehicle can roll
freely. To avoid unwanted vehicle
movement, always fully set the parking
brake prior to doing this procedure. Use
wheel chocks if appropriate. If the parking brake is fully released,
but the brake warning lamp remains
illuminated, the brakes may not be
working properly. See your authorized
dealer. Your vehicle is equipped with a brake-shift
interlock feature that prevents the
gearshift lever from being moved from P
(Park) when the ignition is in the 3 (on)
position and the brake pedal is not pressed.
If you cannot move the gearshift lever out
of P (Park) position with the ignition in the
4 (on) position and the brake pedal
pressed, a malfunction may have occurred.
It is possible that a fuse has blown or the
vehicle
’s brake lamps are not operating
properly. See Fuse Specification Chart
(page 215).
If the fuse is not blown and the brake
lamps are working properly, the following
procedure will allow you to move the
gearshift lever from P (Park):
1. Apply the parking brake. Turn the ignition key to 1 (off), then remove the
key.
2. Move the steering column to the full down and full rearward position
(toward the driver ’s seat).
3. Remove the gearshift lever boot. 4. Place fingers into hole where the
gearshift lever boot was removed from
and pull top half of shroud up and
forward to separate it from the lower
half of the shroud. There is a hinge at
the forward edge of the top shroud.
Roll the top half of the shroud upward
on the hinge point to clear the hazard
flasher button, then pull straight
rearward toward the driver ’s seat to
remove.
5. Remove the top half of the shroud.
6. Remove the three fasteners under the column that secure the lower shroud
half to the column. 7.
Pull the lock lever into the full unlocked
position and remove the lower shroud
cover by pulling the lever handle
through the slot in the cover. 8.
Apply the brake and move the gearshift
lever into N (Neutral).

9. Start the vehicle.
Perform Steps 4 through 8 in reverse order,
making sure to engage the hinge pivots
between the upper and lower halves of the
shroud. Keep slight pressure in the forward
direction as the halves are rotated
together.
If Your Vehicle Gets Stuck In Mud
or Snow
Note:
Do not rock the vehicle if the engine
is not at normal operating temperature or
damage to the transmission may occur.
Note: Do not rock the vehicle for more than
a minute or damage to the transmission and
tires may occur, or the engine may overheat.
If your vehicle gets stuck in mud or snow,
it may be rocked out by shifting between
forward and reverse gears, stopping
between shifts in a steady pattern. Press
lightly on the accelerator in each gear.
POWER TAKE-OFF
Auxiliary equipment called power take-off,
or PTO, is often added to the engine or
transmission to operate utility equipment.
Examples include a wheel-lift for tow
trucks, cranes, tools for construction or tire
service, and pumping fluids. PTO
applications draw auxiliary horsepower
from the powertrain, often while the
vehicle is stationary. In this condition, there
is limited cooling air flow through the
radiator and around the vehicle that
normally occurs when a vehicle is moving.
The aftermarket PTO system installer,
having the most knowledge of the final
application, is responsible for determining
whether additional chassis heat protection
or powertrain cooling is required, and
alerting the user to the safe and proper
operation. Ford Super Duty Vehicles are approved for
use as a stationary (including split shaft
capability) or mobile power source, within
limits and operating guidelines detailed in
the Ford Truck Body Builders Layout Book,
found at www.fleet.ford.com/truckbbas,
and through the Ford Truck Body Builders
Advisory Service.
