2018 FORD F-450 ECO mode

We recommend the following cold
weather idling guidelines:
•
You can use Motorcraft® cetane
improvers or non-alcohol-based
cetane improvers from a reputable
manufacturer as needed.
• Maintain the engine cooling system
properly.
• Avoid shutting the engine down after
an extensive idling period. Drive your
vehicle for several miles with the
engine at normal operating
temperatures under a moderate load.
• Consider using an engine block heater.
• For extended idle times use an
approved idle speed increase device.
Winter Operating Tips for Arctic
Operation -20°F (-29°C) and Below
The following information is a guideline
only and is not to be the only source of
possible solutions in resolving extreme
cold temperature issues.
Starting Aids WARNING
Do not use starting fluid, for example
ether, in the air intake system. Such
fluid could cause immediate
explosive damage to the engine and
possible personal injury. The use of the factory engine block heater
assists in engine starting in extreme cold
ambient temperatures See Engine Block
Heater (page 183). Idle Control
Your vehicle may have a factory option for
a stationary elevated idle control through
the upfitter switches in the overhead
console. This allows the operator to
elevate the idle RPM for extended idle
periods, as well as aftermarket equipment
such as PTO operation. You must configure
this feature even if ordered from the
factory. See your authorized dealer for
required upfitting.
Operation in Snow and Rain
Vehicle operation in heavy snowfall or
extreme rain conditions may feed
excessive amounts of snow or water into
the air intake system. This could plug the
air filter with snow and may cause the
engine to lose power and possibly shut
down.
We recommend the following actions after
operating your vehicle up to
200 mi
(320 km) in snowfall or extreme rain:
• Snow: At the earliest opportunity, open
the hood and clear all the snow and ice
from the air filter housing inlet (do not
remove the foam filter) and reset the
air filter restriction gauge.
Note: Removal of the foam filter degrades
your vehicle performance during snow and
hot weather conditions.
• Extreme rain: The air filter dries after
about 15– 30 minutes at highway
speeds. At the earliest opportunity,
open the hood and reset the air filter
restriction gauge.
Refer to Air filter and restriction gauge in
the Maintenance chapter for more
information. See
Changing the Engine
Air Filter (page 363).

Operation in Standing Water
Ingestion of water into the diesel engine
can result in immediate and severe
damage to the engine. If driving through
water, slow down to avoid splashing water
into the intake. If the engine stalls, and you
suspect ingestion of water into the engine,
do not try to restart the engine. Consult
your dealer for service immediately.
Your fuel tank vents to the atmosphere by
valves on top of the tank and through the
fuel cap. If water reaches the top of the
tank, the valves may pull water into the
fuel tank. Water in the fuel can cause
performance issues and damage the fuel
injection system.
SWITCHING OFF THE ENGINE
- 6.7L DIESEL
Switch the ignition off.
To help prolong engine life, we
recommended you allow the engine to idle
for three to five minutes, especially after
any of the following:
•
Continuous engine speed.
• High ambient temperature.
• High GVW or GCW operation, for
example heavy loads or trailers.
This allows the turbo charged engine to
cool down.
ENGINE IDLE SHUTDOWN
Your vehicle may be equipped with an
engine idle shutdown system. This system
automatically shuts down your engine
when it has been idling in P (Park) or N
(Neutral) for five minutes (parking brake
set) or 15 minutes (parking brake not set).
When the engine idle shutdown process
has started: •
A chime sounds and the information
display will show ENGINE TURNS OFF
IN 30 (seconds) and start counting
down
• You can restart the five or 15-minute
timer by changing the position of the
accelerator pedal, brake pedal or the
park brake within the final 30 seconds
• When the timer reaches zero, the
engine shuts down and this message
will appear in your information display
ENGINE TURNED OFF
• One minute after the engine has shut
down, the electrical system simulates
key off, even though the ignition is still
in the on position, initiating normal
accessory delay period
• You must move the ignition to the off
position to reset the system before
restarting your vehicle.
The engine idle shutdown idle timer does
not start if:
• The engine is operating in power
take-off mode.
• The engine coolant temperature is
below 60°F (16°C).
• The exhaust emission control device is
regenerating.
ENGINE BLOCK HEATER
(If
Equipped) WARNINGS
Failure to follow engine block heater
instructions could result in property
damage or serious personal injury.
Do not use your heater with
ungrounded electrical systems or
two-pronged adapters. There is a risk
of electrical shock. 183
Super Duty (TFE) Canada/United States of America, enUSA, Edition date: 201709, Second Printing Starting and Stopping the Engine

Continued driving without refilling results
in the following actions as required by the
California Air Resources Board (CARB) and
the U.S. Environmental Protection Agency
(EPA):
•
Within a preset distance to empty,
speed is limited upon vehicle restart.
Prior to this occurring a message
appears in the information display.
• Further vehicle operation without
refilling the diesel exhaust fluid tank
causes the engine to enter an idle-only
condition. This only occurs upon vehicle
refueling or at an extended idle. A
message indicates the required actions
to resume normal operation. It is
required to add a minimum of 1.0 gal
(3.8 L) of diesel exhaust fluid to the
tank to exit the idle-only condition, but
your vehicle is still in the speed-limiting
mode until you refill the tank
completely.
Note: For either vehicle speed limiting or
idle-only condition, normal vehicle operation
resumes when you refill the diesel exhaust
fluid tank.
Note: When filling the diesel exhaust fluid
tank from empty, there may be a short delay
before detecting the increased level of fluid.
The increased level detection must occur
before your vehicle returns to full power.
Diesel Exhaust Fluid Guidelines
and Information
• Use only diesel exhaust fluid that
carries the American Petroleum
Institute (API) certified diesel exhaust
fluid trademark or ISO 22241.
• Do not put diesel exhaust fluid in the
diesel fuel tank.
• Do not overfill the diesel exhaust fluid
tank.
• Diesel exhaust fluid is corrosive.
• Do not re-use the diesel exhaust fluid
container once it is emptied. •
Avoid spilling diesel exhaust fluid on
painted surfaces, carpeting or plastic
components. Immediately wipe away
any diesel exhaust fluid that has spilled
with a damp cloth and water. If it has
already crystallized, use warm water
and a sponge.
• Store diesel exhaust fluid out of direct
sunlight and in temperatures between
23°F (-5°C)
and 68°F (20°C).
• Diesel exhaust fluid freezes below 12°F
(-11°C)
.
• Do not store the diesel exhaust fluid
bottle in your vehicle. If it leaks it could
cause damage to interior components
or release an ammonia odor inside your
vehicle.
• Diesel exhaust fluid is non-flammable,
non-toxic, colorless and water-soluble
liquid.
• The system has a diesel exhaust fluid
quality sensor. Dilution of diesel
exhaust fluid or use of any other liquid
in the SCR system leads to a diesel
exhaust fluid system fault, eventually
leading to the vehicle only operating in
idle-only mode.
• Do not dilute diesel exhaust fluid with
water or any other liquid.
• An ammonia odor may be smelled
when the cap is removed or during
refill. Refill diesel exhaust fluid in a well
ventilated area.

First (1)
•
Transmission operates in first (1) gear
only.
• Provides maximum engine braking.
• Allows upshifts by moving gearshift
lever.
• Does not downshift into first (1) gear
at high speeds; allows for first (1) gear
when vehicle reaches slower speeds.
Forced downshifts
• Allowed in drive (D) with the tow/haul
feature on or off.
• Press the accelerator to the floor.
• Allows transmission to select an
appropriate gear.
Tow/Haul Mode WARNING
Do not use tow/haul when the road
surface is slippery. Failure to follow
this instruction could result in the
loss of control of your vehicle. To activate tow/haul, press the
button on the gearshift lever
once. The TOW HAUL indicator
light illuminates in the instrument cluster. The tow/haul feature:
•
Delays upshifts to reduce the frequency
of transmission shifting.
• Provides engine braking in all forward
gears, which slows your vehicle and
assists you in controlling your vehicle
when descending a grade.
• Depending on driving conditions and
load conditions, may downshift the
transmission, slow your vehicle and
control your vehicle speed when
descending a hill, without pressing the
accelerator pedal. The amount of
downshift braking provided varies
based upon the amount you press the
brake pedal.
The tow/haul feature improves
transmission operation when towing a
trailer or a heavy load. All transmission
gear ranges are available when using
tow/haul.
Note: If your vehicle is equipped with the
Adaptive Steering System, enabling the
tow/haul feature adjusts the steering
response. In tow/haul mode the Adaptive
Steering system reduces vehicle sensitivity
to steering inputs at higher vehicle speeds
when maintaining the ease of parking and
maneuverability at low speeds. See
Steering (page 259).
To deactivate the tow/haul feature and
return to normal driving mode, press the
button on the gearshift lever when
tow/haul is active. The TOW HAUL light
deactivates. Tow/haul also deactivates
when you power down your vehicle.

Understanding your SelectShift
Automatic
™ transmission (If Equipped)Your vehicle is equipped with a SelectShift
Automatic
™ transmission gearshift lever.
The SelectShift Automatic transmission
gives you the ability to change gears up or
down (without a clutch) as desired.
In order to prevent the engine from running
at too low an RPM, which may cause it to
stall, SelectShift still automatically make
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 as long as the
SelectShift determines that damage will
not be caused to the engine from
over-revving.
SelectShift does not automatically upshift,
even if the engine is approaching the RPM
limit. It must be shifted manually by
pressing the + button.
Note: Engine damage may occur if you
maintain excessive engine revving without
shifting. The SelectShift Automatic transmission
feature has two modes: PRS and M mode.
PRS (Progressive Range Selection)
Progressive Range Selection gives you the
ability to lockout gears from the automatic
shifting range. This may provide you with
an improved driving experience (for
example, in slippery conditions or when
experiencing a steep grade).
With the gearshift lever in drive (D), press
the – button to active PRS. The available
and selected gears are indicated on the
instrument cluster.
All available gears display with the current
gear indicated. Press the – button again to
lock out gears beginning with the highest
gear. Example: press the – button twice to
lock out 6th and 5th gears. Only the
available gears display and the
transmission automatically shifts between
the available gears. Press the + button to
unlock gears to allow the transmission to
shift to higher gears. The transmission
shifts automatically within the gear range
you select.
Manual (M)
Moving the gearshift lever to the manual
(M) position allows you to manually select
the gear you desire. Only the current gear
displays. Use the buttons on the gearshift
lever to manually select gears. Press the
+ button to upshift or the – button to
downshift. Return the transmission to a
different gearshift position to deactivate
manual control.
