• Make sure the heater, heater cord and
extension cord are firmly connected.
• Check for heat anywhere in the
electrical hookup once the system has
been operating for approximately 30
minutes.
• Make sure the system is unplugged and
properly stowed before starting and
driving your vehicle. Make sure the
protective cover seals the prongs of the
block heater cord plug when not in use.
• Make sure the heater system is
checked for proper operation before
winter.
Using the Engine Block Heater
Make sure the receptacle terminals are
clean and dry prior to use. Clean them with
a dry cloth if necessary.
The heater uses 0.4 to 1.0 kilowatt-hours
of energy per hour of use. The system does
not have a thermostat. It achieves
maximum temperature after
approximately three hours of operation.
Using the heater longer than three hours
does not improve system performance and
unnecessarily uses electricity.

Starting and Stopping the Engine

WARNING: Wait at least five
seconds before removing the fuel pump
nozzle to allow any residual fuel to drain
into the fuel tank.
WARNING: Stop refueling after the
fuel pump nozzle automatically shuts
off for the second time. Failure to follow
this will fill the expansion space in the
fuel tank and could lead to fuel
overflowing.
WARNING: Do not remove the fuel
pump nozzle from its fully inserted
position when refueling.
An engine that suddenly becomes noisy or
operates poorly after a fuel fill could be
using substandard fuel. We recommend
that you purchase diesel fuel from a
reputable fuel station.
Use only clean, approved containers that
prevent the entry of dirt or water whenever
you store diesel fuel.
Do not store diesel fuel in a galvanized
container. The fuel dissolves the zinc in the
galvanized container. The zinc will then
remain in the fuel. If you run the
contaminated fuel through the engine, the
zinc damages the fuel injectors. Engine
damage caused may not be covered by
the vehicle warranty.
Use the following guidelines to avoid
electrostatic charge build-up when filling
an ungrounded fuel container:
• Place the approved fuel container on
the ground.
• Do not fill a fuel container while it is in
the vehicle (including the cargo area).
• Keep the fuel pump nozzle in contact
with the fuel container when filling.
• Do not use a device that would hold
the fuel pump handle in the fill position.
Fuel Filler Cap
WARNING: The fuel system may
be under pressure. If you hear a hissing
sound near the fuel filler inlet, do not
refuel until the sound stops. Otherwise,
fuel may spray out, which could cause
serious personal injury.
Note:If you do not use the correct fuel filler
cap, excessive pressure or vacuum in the
fuel tank may damage the fuel system or
cause the fuel cap to disengage in a crash.
The fuel tank has a threaded fuel filler cap.
Note:If you must replace the fuel filler cap,
replace it with a fuel filler cap that is
designed for your vehicle. The vehicle
warranty may be void for any damage to the
fuel tank or fuel system if the correct
genuine Ford, Motorcraft or other certified
fuel filler cap is not used.
When refueling the vehicle fuel tank do the
following.
1. Bring your vehicle to a complete stop
and shift into neutral (N) or park (P).
2. Apply the parking brake and switch the
ignition off.
3. Turn the fuel filler cap
counterclockwise and remove it.
4. Refuel your vehicle as required.
5. Replace the fuel filler cap, turn it
clockwise until you feel a strong
resistance.
Fuel Fill Rate
Your vehicle has a fuel fill pipe that is able
to accept fuel up to 20 gal (75 L) per
minute from a fuel-dispensing nozzle.
Pumping fuel at greater flow rates may
result in premature nozzle shut off or spit
back.
111
Fuel and Refueling

1. When your vehicle has stopped, shift
into neutral (N) or park (P).
2. Apply the parking brake and switch the
ignition off.
3. Turn the fuel filler cap
counterclockwise and remove it.
4. Refuel your vehicle as required.
5. Replace the fuel filler cap, turn it
clockwise until you feel a strong
resistance.
If the fuel cap warning lamp or a warning
message appears in the instrument cluster,
you may not have installed the fuel filler
cap correctly.
If the fuel cap warning lamp remains on,
at the next opportunity, safely pull off of
the road, remove the fuel filler cap, align
the cap properly and reinstall it. The check
fuel cap warning lamp or warning message
may not reset immediately. It may take
several driving cycles for the indicators to
turn off. A driving cycle consists of an
engine start-up (after four or more hours
with the engine off) followed by normal
city and highway driving.
FUEL CONSUMPTION
The advertised capacity is the maximum
amount of fuel that you can add to the fuel
tank after running out of fuel. Included in
the advertised capacity is an empty
reserve. The empty reserve is an
unspecified amount of fuel that remains
in the fuel tank when the fuel gauge
indicates empty.
Note:The amount of fuel in the empty
reserve varies and should not be relied upon
to increase driving range.
Filling the Fuel Tank
For consistent results when refueling:
• 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 one automatic
shut-off when refueling.
Results are most accurate when the filling
method is consistent.
Calculating Fuel Economy
Do not measure fuel economy during the
first 1,000 mi (1,600 km) of driving (this is
your engine’s break-in period). A more
accurate measurement is obtained after
2,000 mi (3,200 km) to 3,000 mi
(4,800 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.
To calculate L/100 km (liters per 100
kilometers) fuel consumption, multiply the
liters used by 100, then divide by kilometers
traveled. To calculate MPG (miles per
gallon) fuel consumption, divide miles
traveled by gallons used.

Transmission

To prevent the engine from running at too
low an RPM, which could cause it to stall,
SelectShift still makes some downshifts
if it has determined that you have not
downshifted in time. Although SelectShift
makes some downshifts for you, it still
allows you to downshift at any time if the
SelectShift determines that there is no
damage to the engine from over-revving.
SelectShift does not automatically upshift,
even if the engine is approaching the RPM
limit. Shift manually by pressing the (+)
button.
Note:Engine damage could occur if you rev
the engine excessively and hold it without
shifting.
Progressive Range Selection (If
Equipped)
Progressive range selection gives you the
ability to lockout gears from the automatic
shifting range. This could provide you with
an improved driving experience, for
example, in slippery conditions or when
experiencing a steep slope.
With the gearshift lever in drive (D), press
the (–) button to activate progressive
range selection. The instrument cluster
indicates the available and selected gears.
All available gears display with the current
gear indicated. Press the (–) button again
to lock out gears beginning with the highest
gear. For example, press the (–) button
twice to lock out 6th and 5th gears. Only
the available gears display, and the
transmission shifts between the available
gears. Press the (+) button to unlock gears
to allow the transmission to shift to higher
gears. The transmission shifts within the
gear range you select.
Automatic Transmission at a Stop
(If Equipped)
Your transmission could reduce the load
on the engine when the vehicle stops, and
the gear selector is in drive (D) to reduce
fuel consumption and emissions. The
transmission resumes operation when you
release the brake. This feature activates
when the transmission is sufficiently
warmed, and the vehicle is on a level slope.
Automatic Transmission Adaptive
Learning
This feature could increase durability and
provide consistent shift feel over the life
of your vehicle. A new vehicle or
transmission may have firm shifts, soft
shifts, or both. This is normal and does not
affect the function or durability of the
transmission. Over time, the adaptive
learning process fully updates transmission
operation.
Brake-Shift Interlock
WARNING: Do not drive your
vehicle until you verify that the
stoplamps are working.
WARNING: When doing this
procedure, you need to take the
transmission out of park (P) which
means your vehicle can roll freely. To
avoid unwanted vehicle movement,
always fully apply the parking brake prior
to doing this procedure. Use wheel
chocks if appropriate.
WARNING: If the parking brake is
fully released, but the brake warning
lamp remains illuminated, the brakes
may not be working properly. Have your
vehicle checked as soon as possible.
131
Transmission

Your vehicle has a brake-shift interlock
feature that prevents the gearshift lever
from moving from park (P) when you
switch the ignition on but have not pressed
the brake pedal.
If you cannot move the gearshift lever out
of the park (P) position with the ignition in
the on position and the brake pedal
pressed, a malfunction could have
occurred. It is possible that a fuse has
blown, or your vehicle’s brake lamps are
not operating properly. See Fuse
Specification Chart (page 200).
If you do not have a blown fuse and the
brake lamps are working properly, the
following procedure allows you to move
the gearshift lever from park (P):
1. Apply the parking brake. Switch the
ignition key to off, then remove the key.
2. Move the steering column to the full
down and full rearward position,
toward the driver seat.
3. Remove the gearshift lever boot.
4. Place your fingers into the hole where
you removed the gearshift lever boot
and pull the top half of the 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 of
the shroud. Roll the top half of the
shroud upward on the hinge point, then
pull straight rearward toward the driver
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.

WHAT IS THE PNEUMATIC
LOCKING DIFFERENTIAL
The pneumatic locking differential can lock
or unlock the differential when the vehicle
is moving or stopped. The differential lock
provides full power to both wheels when
extra traction is required.
HOW DOES THE PNEUMATIC
LOCKING DIFFERENTIAL
WORK
If your vehicle is equipped with a
pneumatic locking differential:
• Power is transmitted to the opposite
wheel should one of the wheels begin
to slip.
• Raise both wheels off the ground if it
becomes necessary to operate one
wheel with the vehicle stationary.
The differential can be locked or unlocked
when the vehicle is moving at a constant
speed of less than 25 mph (40 km/h) and
while the wheels are not slipping. Do not
lock the differential when the vehicle is
traveling down steep grades and traction
is minimal.
Note:Do not use the differential lock at
vehicle speeds above 25 mph (40 km/h).
When the differential is locked, the
vehicle’s turning radius increases causing
understeer.
The differential lock and differential lock
light automatically disengage at speeds
above 25 mph (40 km/h). The differential
lock remains off until the vehicle is
restarted or the differential lock switch is
turned off then back on.
PNEUMATIC LOCKING
DIFFERENTIAL PRECAUTIONS
WARNING: Exceeding any vehicle
weight rating can adversely affect the
performance and handling of your
vehicle, cause vehicle damage and can
result in the loss of control of your
vehicle, serious personal injury or death.
WARNING: Failure to raise all drive
wheels with this type of differential could
cause the vehicle to move unexpectedly,
resulting in property damage, personal
injury or death.
WARNING: Sudden acceleration
on slippery surfaces could cause the
wheels to spin, the vehicle to turn
sideways on a crowned road surface or
in a turn, possibly resulting in loss of
vehicle control and personal injury.
SWITCHING THE PNEUMATIC
LOCKING DIFFERENTIAL ON
AND OFF
Press and hold the button on the dash to
turn the system on or off.
