ECO mode FORD F-450 2018 Repair Manual

Benefits of engine braking are:
•
Lower brake temperature.
• Reduced brake fade.
• Longer brake life.
• Improved driving and trailering control. Press the button on the switch
bank next to the audio unit to
switch the system on or off.
There are two engine brake modes, manual
and automatic.
Manual Engine Braking
1. Press the button to switch on manual engine braking.
2. Release the accelerator pedal to maximize engine braking.
3. Apply the brakes. The transmission downshifts to lower gears.
Note: The engine braking feature only
functions when you release the accelerator.
Note: You can shift the transmission to
lower gears with progressive range selection
(PRS) or manual shifting independent of
pressing the brakes.
Note: You can also use manual engine
braking with cruise control to improve grade
descent control.
Note: If your vehicle has Adaptive Cruise
Control, the speed control system uses the
selected engine brake mode, transmission
gears, and brakes to maintain the set speed
and distance to the vehicle being followed.
Automatic Engine Braking
1. Press the button twice to switch on automatic engine braking.
2. Release the accelerator or brake pedal.
The system remembers your vehicle
speed. Note:
This feature offers smoother, less
aggressive engine braking during downhill
descents. It may not apply braking if the
vehicle speed is not increasing, although it
will apply full engine braking force when
needed to prevent acceleration. The system
automatically activates the engine brake
and, if necessary, downshifts the
transmission to lower gears to not exceed
your vehicle's set speed when the brake or
accelerator were last released.
Warning Lamp Conditions
• Illuminates when this feature is
switched on and the system is
operating properly. See Warning
Lamps and Indicators (page 108).
• Flashes when the engine brake is
disabled due to a fault or the engine
does not meet the required braking
conditions.
• Does not illuminate when the switch
or indicator is faulty.
You can switch the system on at anytime.
The system becomes active once the
braking conditions are met.
Braking Conditions
• Your vehicle is in a forward gear.
• The engine speed is above about 1500
RPM.
• Your foot is off the accelerator.
You can use this feature with tow/haul or
progressive range selection to provide
further increased engine braking. The
transmission automatically upshifts to
prevent the engine from entering the red
zone on the tachometer.
See Automatic
Transmission (page 208).

PRINCIPLE OF OPERATION
The traction control system helps avoid
drive wheel spin and loss of traction.
If your vehicle begins to slide, the system
applies the brakes to individual wheels
and, when needed, reduces engine power
at the same time. If the wheels spin when
accelerating on slippery or loose surfaces,
the system reduces engine power in order
to increase traction.
USING TRACTION CONTROL
WARNING
The stability and traction control
light illuminates steadily if the
system detects a failure. Make sure
you did not manually disable the traction
control system using the information
display controls or the switch. If the
stability control and traction control light
is still illuminating steadily, have the
system serviced by an authorized dealer
immediately. Operating your vehicle with
the traction control disabled could lead to
an increased risk of loss of vehicle control,
vehicle rollover, personal injury and death. The system automatically turns on each
time you switch the ignition on.
If your vehicle is stuck in mud or snow,
switching traction control off may be
beneficial as this allows the wheels to spin.
Note:
When you switch traction control off,
stability control remains fully active.
Note: For additional information on the
traction and stability control systems. See
Using Stability Control (page 231).
Switching the System Off
When you switch the system off or on, a
message appears in the information
display showing system status. Use the traction and stability control
switch on the instrument panel to switch
the system off or on.
The switch illuminates when traction
control is off.
When you place your vehicle into
four-wheel drive low mode the traction
control disables. Traction control resumes
full operation when you put your vehicle
back into two-wheel drive mode.
System Indicator Lights and
Messages
The stability and traction control
light:
• Temporarily illuminates on engine
start-up.
• Flashes when a driving condition
activates either of the systems.
• Illuminates if a problem occurs in either
of the systems. The stability and traction control
off light temporarily illuminates
on engine start-up and stays on
when you switch the traction control
system off.

PRINCIPLE OF OPERATION
WARNINGS
Hill descent control cannot control
descent in all surface conditions and
circumstances, such as ice or
extremely steep grades. Hill descent
control is a driver assist system and cannot
substitute for good judgment by the driver.
Failure to do so may result in loss of vehicle
control, crash or serious injury. Hill descent control does not provide
hill hold at zero miles per hour (0
kilometers per hour). When stopped,
the parking brake must be applied or the
vehicle must be placed in P (Park) or it
may roll away. Hill descent control allows the driver to set
and maintain vehicle speed while
descending steep grades in various surface
conditions.
Hill descent control can maintain vehicle
speeds on downhill grades between 2 mph
(3 km/h) and 12 mph (20 km/h). Above 20
mph (32 km/h), the system remains
armed, but descent speed cannot be set
or maintained.
Hill descent control requires a cooling
down interval after a period of sustained
use. The amount of time that the feature
can remain active before cooling varies
with conditions. The system will provide a
warning in the message center and a chime
will sound when the system is about to
disengage for cooling. At this time,
manually apply the brakes as needed to
maintain descent speed. USING HILL DESCENT
CONTROL Press and release the hill
descent button located on the
instrument panel. A light in the
cluster will illuminate and a chime will
sound when this feature is activated.
To increase descent speed, press the
accelerator pedal until the desired speed
is reached. To decrease descent speed,
press the brake pedal until the desired
speed is reached.
Whether accelerating or decelerating, once
the desired descent speed is reached,
remove your feet from the pedals and the
chosen vehicle speed will be maintained.
Note: Noise from the ABS pump motor may
be observed during hill descent control
operation. This is a normal characteristic of
the ABS and should be no reason for
concern.
Hill descent modes
• At speeds below 20 mph (32 km/h):
When the Hill Descent Control switch
is pressed and Hill Descent Control is
active, the Hill Descent Control telltale
will flash.
• At speeds below 20 mph (32 km/h):
When the Hill Descent Control switch
is pressed and conditions are not
correct for hill descent activation, the
Hill Descent Control system will be
enabled, the Hill Descent Control
telltale will be solid and a message will
display in the information display.
• At speeds above 20 mph (32 km/h):
When the Hill Descent Control switch
is pressed, the Hill Descent Control
system will be enabled, the telltale in
the cluster will not be illuminated and
a message will be displayed in the
information display.

PRINCIPLE OF OPERATION
Cruise control lets you maintain a set
speed without keeping your foot on the
accelerator pedal. You can use cruise
control when your vehicle speed is greater
than 20 mph (30 km/h).
USING CRUISE CONTROL WARNINGS
Do not use cruise control on winding
roads, in heavy traffic or when the
road surface is slippery. This could
result in loss of vehicle control, serious
injury or death. When you are going downhill, your
vehicle speed could increase above
the set speed. The system does not
apply the brakes. Note:

audible warning sounds and a message
appears in the information display.
Automatic braking releases.
Hilly Condition and Trailer Tow
Usage
Note: An audible alarm sounds and the
system shuts down if it applies brakes for
an extended period of time. This allows the
brakes to cool. The system functions
normally again after the brakes cool. Note:
When towing with adaptive cruise
control, switch on Tow/Haul Mode and
Diesel Engine Brake.
Note: Tow/Haul mode increases the time
gaps and allows more distance for braking.
Select a lower gear when the system is
active in situations such as prolonged
downhill driving on steep grades, for
example in mountainous areas. The
system needs additional engine braking in
these situations to reduce the load on the
vehicle ’s regular brake system to prevent
it from overheating.
Switching Adaptive Cruise Control
Off
Note: You erase the set speed and gap
setting when you switch the system off.
Press
OFF when the system is in standby
mode, or switch the ignition off.
Detection Issues WARNINGS
On rare occasions, detection issues
can occur due to the road
infrastructures, for example bridges,
tunnels and safety barriers. In these cases,
the system may brake late or
unexpectedly. At all times, you are
responsible for controlling your vehicle,
supervising the system and intervening, if
required. If the system malfunctions, have your
vehicle checked as soon as possible.
The radar sensor has a limited field of view.
It may not detect vehicles at all or detect
a vehicle later than expected in some
situations. The lead vehicle graphic does
not illuminate if the system does not
detect a vehicle in front of you.

Calculating the Maximum
Loaded Trailer Weight for Your
Vehicle
1. Start with the gross combined weight rating for your vehicle
model and axle ratio. See the
previous chart.
2. Subtract all of the following
that apply to your vehicle:
• Vehicle curb weight.
• Hitch hardware weight, such as
a draw bar, ball, locks or weight
distributing hardware.
• Driver weight.
• Passenger(s) weight. •
Payload, cargo and luggage
weight.
• Aftermarket equipment weight.
This equals the maximum loaded
trailer weight for this combination.
Note: The trailer tongue load is
considered part of the payload for
your vehicle. Reduce the total
payload by the final trailer tongue
weight.
Note: Consult an authorized dealer
to determine the maximum trailer
weight allowed for your vehicle if
you are not sure.

Trailer Brake Effort Setting
The trailer brake controller allows the user
to customize how aggressively the trailer
brakes engage. The default value is the low
setting and is the recommended setting
for most trailers. If your trailer's brakes
require more initial voltage, or if you prefer
more aggressive trailer braking, then select
either the medium or the high setting.
Procedure for Setting Trailer Brake
Controller Mode
Choose the low, medium or high setting
for the required initial trailer brake output.
Procedure for Adjusting Gain
Note:
Only perform this procedure in a
traffic-free environment at speeds of
approximately 20– 25 mph (30–40 km/h).
The gain setting adjusts the trailer brake
controller for the specific towing condition.
You should change the setting as towing
conditions change. Changes to towing
conditions include trailer load, vehicle load,
road conditions and weather.
The gain should be set to provide the
maximum trailer braking assistance while
making sure the trailer wheels do not lock
when using the brakes. Locked trailer
wheels may lead to trailer instability.
1. Make sure the trailer brakes are in good
working condition, functioning normally
and properly adjusted. See your trailer
dealer if necessary.
2. Hook up the trailer and make the electrical connections according to the
trailer manufacturer's instructions.
3. When you plug in a trailer with electric or electric-over-hydraulic brakes, a
confirmation message appears in the
information display. 4. Use the gain adjustment (+ and -)
buttons to increase or decrease the
gain setting to the desired starting
point. A gain setting of 6.0 is a good
starting point for heavier loads.
5. In a traffic-free environment, tow the trailer on a dry, level surface at a speed
of
20– 25 mph (30–40 km/h) and
squeeze the manual control lever
completely.
6. If the trailer wheels lock up, indicated by squealing tires, reduce the gain
setting. If the trailer wheels turn freely,
increase the gain setting. Repeat Steps
5 and 6 until the gain setting is at a
point just below trailer wheel lock-up.
If towing a heavier trailer, trailer wheel
lock-up may not be attainable even
with the maximum gain setting of 10.
Information Display Warning Messages
Note: An authorized dealer can diagnose
the trailer brake controller to determine
exactly which trailer fault has occurred.
However, your Ford warranty does not cover
this diagnosis if the fault is with the trailer.
TRAILER BRAKE MODULE FAULT
Displays in response to faults sensed by
the trailer brake controller, accompanied
by a single tone. If this message appears,
contact an authorized dealer as soon as
possible for diagnosis and repair. The
controller may still function, but with
degraded performance.
WIRING FAULT ON TRAILER
Displays when there is a short circuit on
the electric brake output wire.
If this message displays, with no trailer
connected, the problem is with your vehicle
wiring or trailer brake controller. Contact
an authorized dealer.
