engine FORD F450 SUPER DUTY 2020 Manual Online

When the system is active, your vehicle
remains stationary on the slope for two to
three seconds after you release the brake
pedal. This allows time to move your foot
from the brake to the accelerator pedal.
The system releases the brakes
automatically once the engine has
developed sufficient torque to prevent your
vehicle from rolling down the slope. This
is an advantage when pulling away on a
slope, for example from a car park ramp,
traffic lights or when reversing uphill into
a parking space.
The system activates on any slope that
causes your vehicle to roll.
Note:
There is no warning light to indicate
the system is either on or off.
Using Hill Start Assist
1. Press the brake pedal to bring your vehicle to a complete standstill. Keep
the brake pedal pressed and shift into
first gear when facing uphill or reverse
(R) when facing downhill.
2. If the sensors detect that your vehicle is on a slope, the system activates
automatically.
3. When you remove your foot from the brake pedal, your vehicle remains on
the slope without rolling away for
about two to three seconds. This hold
time automatically extends if you are
in the process of driving off.
4. Drive off in the normal manner. The system releases the brakes
automatically.
Note: When you remove your foot from the
brake pedal and press the pedal again when
the system is active, you will experience
significantly reduced brake pedal travel. This
is normal. Switching the System On and Off
Vehicles with Manual Transmission
You can switch this feature on or off in the
information display. The system
remembers the last setting when you start
your vehicle.
Vehicles with Automatic Transmission
You cannot turn the system on or off.
When you switch the ignition on, the
system automatically turns on.

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 228). 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
WARNING: Vehicle modifications
involving braking system, aftermarket
roof racks, suspension, steering system,
tire construction and wheel and tire size
may change the handling characteristics
of your vehicle and may adversely affect
the performance of the electronic
stability control system. In addition,
installing any stereo loudspeakers may
interfere with and adversely affect the
electronic stability control system. Install
any aftermarket stereo loudspeaker as
far as possible from the front center
console, the tunnel, and the front seats
in order to minimize the risk of interfering
with the electronic stability control
sensors. Reducing the effectiveness of
the electronic stability control system
could lead to an increased risk of loss of
vehicle control, vehicle rollover, personal
injury and death. WARNING:
Remember that even
advanced technology cannot defy the
laws of physics. It’ s always possible to
lose control of a vehicle due to
inappropriate driver input for the
conditions. Aggressive driving on any
road condition can cause you to lose
control of your vehicle increasing the risk
of personal injury or property damage.
Activation of the electronic stability
control system is an indication that at
least some of the tires have exceeded
their ability to grip the road; this could
reduce the operator ’s ability to control
the vehicle potentially resulting in a loss
of vehicle control, vehicle rollover,
personal injury and death. If your
electronic stability control system
activates, SLOW DOWN.
The system automatically turns on each
time you switch the ignition on. If a fault occurs in either the stability
control or the traction control system, you
may experience the following conditions:
•
The stability and traction control light
illuminates steadily.
• The stability control and traction
control systems do not enhance your
vehicle's ability to maintain traction of
the wheels.
• The Adaptive Steering system (if
equipped) automatically changes the
steering function to a fixed steering
ratio. See
Steering (page 261).
If a driving condition activates either the
stability control or the traction control
system you may experience the following
conditions:
• The stability and traction control light
flashes.
• Your vehicle slows down.
• Reduced engine power.
• A vibration in the brake pedal.
• The brake pedal is stiffer than usual.
• If the driving condition is severe and
your foot is not on the brake, the brake
pedal may move as the system applies
higher brake force.
The stability control system has several
features built into it to help you maintain
control of your vehicle:
Electronic Stability Control
The system enhances your vehicle ’s ability
to prevent skids or lateral slides by
applying brakes to one or more of the
wheels individually and, if necessary,
reducing engine power.

Overriding the Set Speed
WARNING: If you override the
system by pressing the accelerator
pedal, it does not automatically apply
the brakes to maintain a gap from any
vehicle ahead.
When you press the accelerator pedal, you
override the set speed and gap distance. Use the accelerator pedal
normally to intentionally exceed
the set speed limit.
When you override the system, the green
indicator light illuminates and the vehicle
image does not appear in the information
display.
The system resumes operation when you
release the accelerator pedal. The vehicle
speed decreases to the set speed, or a
lower speed if following a slower vehicle.
Changing the Set Speed Press and release to increase the
set speed in small increments.
Press and release to decrease
the set speed in small
increments.
Press and hold either button to change the
set speed in large increments. Release the
button when you reach your preferred
speed.
The system may apply the brakes to slow
the vehicle to the new set speed. The set
speed displays continuously in the
information display when the system is
active.
Canceling the Set Speed Press and release the button or
tap the brake pedal. The set speed does not erase.
Note:
If you press the clutch pedal (manual
transmission only) for an extended period,
this action also cancels the set speed.
Resuming the Set Speed Press and release the button.
Your vehicle speed returns to the
previously set speed and gap setting. The
set speed displays continuously in the
information display when the system is
active.
Note: Only use resume if you are aware of
the set speed and intend to return to it.
Automatic Cancellation
The system is not functional at vehicle
speeds below 12 mph (20 km/h). The
information display indicates low engine
speed, an audible alarm sounds and the
automatic braking releases if the vehicle
drops below this speed.
Automatic cancellation can also occur
when:
• The tires lose traction.
• You apply the parking brake.
Note: If the engine speed drops too low, an
audible warning sounds and a message
appears in the information display.
Automatic braking releases.
Hilly Condition and Trailer Tow
Usage
You should 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.

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.
Switching Adaptive Cruise Control
Off Press and release the button
when the system is in standby
mode, or switch the ignition off.
Note: You erase the set speed and gap
setting when you switch the system off.
Detection Issues WARNING: 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. WARNING:
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. Detection issues can occur:
When driving on a different line
than the vehicle in front.
A
With vehicles that edge into your
lane. The system can only detect
these vehicles once they move
fully into your lane.
B
There may be issues with the
detection of vehicles in front
when driving into and coming out
of a bend or curve in the road.
C
In these cases, the system may brake late
or unexpectedly. You should stay alert and
take action when necessary.
If something hits the front end of your
vehicle or damage occurs, the
radar-sensing zone may change. This could
cause missed or false vehicle detection.

CROSS TRAFFIC ALERT (IF
EQUIPPED) WARNING:
Do not use the cross
traffic alert system as a replacement for
using the interior and exterior mirrors or
looking over your shoulder before
reversing out of a parking space. The
cross traffic alert system is not a
replacement for careful driving. WARNING:
The system may not
operate properly during severe weather
conditions, for example snow, ice, heavy
rain and spray. Always drive with due
care and attention. Failure to take care
may result in a crash. The system alerts you of vehicles
approaching from the sides behind your
vehicle when you shift into reverse (R).
Using Cross Traffic Alert
The system detects vehicles that approach
at a speed between
4 mph (6 km/h) and
37 mph (60 km/h). Coverage decreases
when the sensors are partially, mostly or
fully obstructed. Slowly reversing helps
increase the coverage area and
effectiveness.
The system turns on when you start the
engine and you shift into reverse (R). The
system turns off when you shift out of
reverse (R). The sensor on the left-hand side is only
partially obstructed and zone coverage on
the right-hand side is maximized.

STEERING
Hydraulic Power Steering
To help prevent damage to the power
steering system:
•
Do not hold the steering wheel at its
furthest turning points for more than
three to five seconds when the engine
is running.
• Avoid continuously steering back and
forth with elevated engine RPM as this
may overheat the system. If trying to
free a stuck vehicle, pause between
attempts to allow the power steering
system to cool or seek assistance.
Typical steering and driving maneuvers
allow the system to cool.
• Do not operate the vehicle if the power
steering pump fluid level is below the
MIN mark on the reservoir.
• Some noise is normal during operation.
If excessive, check for low power
steering pump fluid level before
seeking service by your dealer.
• Heavy or uneven efforts may be caused
by low power steering fluid. Check for
low power steering pump fluid level
before seeking service by your dealer.
• Do not fill the power steering pump
reservoir above the MAX mark on the
reservoir, as this may result in leaks
from the reservoir.
If the power steering system breaks down
or if you switch the engine off, you can
steer the vehicle manually, but it takes
more effort.
If you have any steering components
serviced or replaced, install new fasteners.
Many fasteners have coatings with thread
adhesive, or have prevailing torque
features you cannot reuse. Do not reuse a
bolt or nut. Torque fasteners to
specifications. Steering Tips
If the steering wanders or pulls, check for:
•
An improperly inflated tire.
• Uneven tire wear.
• Loose or worn suspension
components.
• Loose or worn steering components.
• Improper vehicle alignment.
Note: A high crown in the road or high
crosswinds may also make the steering
seem to wander or pull.
Electronic Torque Overlay Steering
(If Equipped) WARNING: The electric power
steering system has diagnostic checks
that continuously monitor the system. If
a fault is detected, a message displays
in the information display. Stop your
vehicle as soon as it is safe to do so.
Switch the ignition off. After at least 10
seconds, switch the ignition on and
watch the information display for a
steering system warning message. If a
steering system warning message
returns, have the system checked as
soon as possible. WARNING:
If the system detects
an error, you may not feel a difference in
the steering, however a serious condition
may exist. Have your vehicle checked as
soon as possible. Failure to do so may
result in loss of steering control.

when the road surface is slippery. Failure
to follow this instruction could result in
the loss of control of your vehicle. Tow/Haul – For improved
transmission operation when
towing a trailer or a heavy load.
This mode moves upshifts to higher engine
speeds to reduce the frequency of
transmission shifting. This mode also
provides engine braking in all forward
gears, which slows your vehicle and assists
you in controlling your vehicle when
descending a grade. The amount of
downshift braking provided varies based
on the amount you press the brake pedal. Deep Snow/Sand – For snow or
soft, dry sand.
Eco – For efficient driving. This
mode helps deliver maximum
fuel efficiency and helps to
increase driving range. Slippery – For less than ideal
road conditions such as snow or
ice covered roads. Use this mode
for crossing terrain where loose, wet or
slippery material covers a firm surface.
Slippery mode lowers throttle response
and, if equipped with automatic
transmission, optimizes shifting for slippery
surfaces. Rock Crawl – For optimum
rock-climbing ability. Rock crawl
mode prompts you to put your
vehicle in 4x4 Low. Rock Crawl mode
optimizes the throttle and transmission
response to provide you additional control
of your vehicle. See

TOWING A TRAILER
WARNING: Do not exceed
the GVWR or the GAWR
specified on the certification
label. WARNING:
Towing trailers
beyond the maximum
recommended gross trailer
weight exceeds the limit of your
vehicle and could result in engine
damage, transmission damage,
structural damage, loss of
vehicle control, vehicle rollover
and personal injury. WARNING:
Do not exceed
the lowest rating capacity for
your vehicle or trailer hitch.
Overloading your vehicle or
trailer hitch can impair your
vehicle stability and handling.
Failure to follow this instruction
could result in the loss of control
of your vehicle, personal injury or
death. WARNING:
Do not cut,
drill, weld or modify the trailer
hitch. Modifying the trailer hitch
could reduce the hitch rating. Note:
To prevent your trailer from
accumulating distance, and the
trailer information status appearing
when you restart your vehicle after
disconnecting your trailer, you must
deactivate your trailer. Using the
information display, go to the
Towing menu and then the Select
Trailer option. Select the No active
trailer option. See
Information
Displays (page 112).
Your vehicle may have electrical
items, such as fuses or relays,
related to towing. See
Fuses
(page 334).
Your vehicle may have ability to
modify trailer towing features.
See
General Information (page
112).
Your vehicle's load capacity
designation is by weight, not by
volume, so you cannot necessarily
use all available space when
