2022 FORD F-450 warning

WHAT IS HILL START ASSIST
Hill Start Assist makes it easier for you to
pull away when your vehicle is on a slope
without using the parking brake.
HOW DOES HILL START
ASSIST WORK
When the system activates, your vehicle
remains stationary for a few seconds after
you release the brake pedal. This gives you
time to move your foot from the brake
pedal to the accelerator pedal. The brakes
release when the engine has developed
sufficient torque to prevent your vehicle
from rolling down the slope.
HILL START ASSIST
PRECAUTIONS
WARNING: The system does not
replace the parking brake. When you
leave your vehicle, always apply the
parking brake. WARNING:
You must remain in
your vehicle when the system turns on.
At all times, you are responsible for
controlling your vehicle, supervising the
system and intervening, if required.
Failure to take care may result in the loss
of control of your vehicle, serious
personal injury or death. WARNING:
The system turns off if
there is a malfunction or if you
excessively rev the engine. HILL START ASSIST –

WHAT IS TRACTION CONTROL
The traction control system helps to avoid
drive wheel spin and loss of traction.
HOW DOES TRACTION
CONTROL WORK
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.
SWITCHING TRACTION
CONTROL ON AND OFF
WARNING: 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 traction control system turns on each
time you switch the ignition on.
The button for the stability and traction
control system is on the instrument panel. Press and release the button to switch
traction control off. The stability control
system remains fully active, to switch it off,
press and hold the button for a few
seconds, then release.
When you switch traction control off, a
message and an illuminated icon appear
on the instrument cluster.
Press the switch again to turn the traction
control system back on to normal
operation.
If your vehicle is stuck in mud or snow,
switching traction control off may be
beneficial as this allows the wheels to spin.
Your vehicle may have MyKey restrictions
regarding this feature. See
What Is
MyKey (page 77).

HOW DOES STABILITY
CONTROL WORK
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 speakers may
interfere with and adversely affect the
electronic stability control system.
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. WARNING: You are responsible for
controlling your vehicle at all times. The
system is designed to be an aid and does
not relieve you of your responsibility to
drive with due care and attention. Failure
to follow this instruction could result in
the loss of control of your vehicle,
personal injury or death.
If a driving condition activates either the
stability control or traction control you may
experience the following conditions:
• The stability and traction control light
flashes.
• Your vehicle slows down.
• Reduced engine power.
The stability control system has several
features built into it to help you maintain
control of your vehicle:
Electronic Stability Control
Electronic stability control 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.
Roll Stability Control
Roll stability control enhances your
vehicle ’s ability to prevent rollovers by
detecting your vehicle ’s roll motion and
the rate at which it changes by applying
the brakes to one or more wheels
individually.
Curve Control
Curve control enhances your vehicle ’s
ability to follow the road when cornering
severely or avoiding objects in the roadway.
Curve control operates by reducing engine
power and, if necessary, applying brakes
to one or more of the wheels individually.

control speed in low traction conditions
or extremely steep slopes. The system
is designed to be an aid and does not
relieve you of your responsibility to drive
with due care and attention. Failure to
follow this instruction could result in
personal injury.
Trail control lets you focus on steering
during low-speed and off-road use by
controlling your vehicle's acceleration and
braking to maintain the speed that you set.
You may hear a noise from the anti-lock
brake system pump motor when you use
the system. This is normal.
SWITCHING TRAIL CONTROL
ON AND OFF Press the button.

WHAT IS HILL DESCENT
CONTROL
Hill descent control allows the driver to set
and maintain vehicle speed while
descending steep slopes in various surface
conditions.
HOW DOES HILL DESCENT
CONTROL WORK
Hill descent control can maintain vehicle
speeds on downhill slopes between
2
– 20 mph (3– 32 km/h). Above 20 mph
(32 km/h), the system remains on but the
descent speed cannot be set or
maintained.
Note: The system does not function below
2 mph (3 km/h)
.
The system requires a cool down interval
after a period of sustained use. Hill descent
control provides a warning in the message
center and a tone sounds when the system
is about to disengage for cooling. At this
time, manually apply the brakes as needed
to maintain descent speed.
Note: The amount of time that the system
can remain active before cooling varies with
conditions.
HILL DESCENT CONTROL
PRECAUTIONS WARNING:
The system does not
control speed in low traction conditions
or extremely steep slopes. The system
is designed to be an aid and does not
relieve you of your responsibility to drive
with due care and attention. Failure to
follow this instruction could result in
personal injury. WARNING:
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. WARNING:

HYDRAULIC POWER
STEERING
HYDRAULIC POWER STEERING
GUIDELINES
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.

2022 Super Duty (TFE) Canada/United States of America, enUSA, Edition date: 202103, First-Printing Steering

The electronic torque overlay steering
system adds supplemental steering assist
to the hydraulic gear when needed,
dependent on vehicle conditions such as
vehicle speed, steering wheel angle, and
steering wheel torque. The hydraulic
steering system provides the majority of
steering assistance. The electronic torque
overlay enables features such as pro trailer
backup assistance and lane departure
warning.
If your vehicle loses electrical power while
you are driving, your vehicle loses electric
power steering assistance. The steering
system still operates, and you can steer
your vehicle with hydraulic assist. Steering
your vehicle with only hydraulic assist
requires more effort.
Extreme continuous steering may increase
the effort required for you to steer your
vehicle. This increased effort prevents
overheating and permanent damage to
the steering system. You do not lose the
ability to steer your vehicle manually.
Typical steering and driving maneuvers
allow the system to cool and return to
normal operation.
Adaptive Learning (If Equipped)
The electronic power steering system
adaptive learning helps correct road
irregularities and improves overall handling
and steering feel. It communicates with
the brake system to help operate
advanced stability control and accident
avoidance systems. Whenever the battery
is disconnected or a new battery installed,
you must drive your vehicle a short
distance before the system relearns the
strategy and reactivates all systems. LOCATING THE HYDRAULIC
POWER STEERING FLUID
RESERVOIR
The hydraulic power steering fluid reservoir
is found in the engine compartment.
See
Under Hood Overview (page 397).
CHECKING THE HYDRAULIC
POWER STEERING FLUID
Check the power steering fluid. See
Scheduled Maintenance
(page 622). If
adding fluid is necessary, use only
MERCON LV ATF.
Check the fluid level when it is at ambient
temperature.
1. Check the fluid level in the reservoir. It should be between the MIN and MAX
range. Do not add fluid if the level is
within this range.
2. If the fluid level is low, add fluid to bring
the fluid level up to between the MIN
and MAX range.
3. Switch the engine on.
4. While the engine idles, turn the steering
wheel left and right several times.
5. Switch the engine off.
6. Recheck the fluid level in the reservoir. Do not add fluid if the level is between
the MIN and MAX range.
7. If the fluid is low, add fluid in small amounts, continuously checking the
level until it is between the MIN and
MAX range. For proper fluid type, See
Capacities and Specifications (page
467
). Be sure to put the cap back on the
reservoir.

HYDRAULIC POWER STEERING
ADAPTIVE STEERING
Note:
The adaptive steering system has
diagnostic checks that continuously monitor
the system. If the system detects a fault, a
message displays in the information display.
If a red warning message displays, stop your
vehicle as soon as it is safe to do so. The
message may clear if the fault is no longer
present. If an adaptive steering system
warning message appears each time you
start your vehicle, have the system checked
as soon as possible.
The adaptive steering system continually
changes the steering ratio with changes to
vehicle speed, optimizing the steering
response in all conditions. The system also
changes when you switch on the
transmission tow/haul feature. When you
select the tow/haul button, the adaptive
steering system reduces vehicle sensitivity
to steering inputs at higher vehicle speeds,
while maintaining the ease of parking and
maneuverability at low speeds.
Note: The adaptive steering system is
designed with a locking device. With the
lock engaged, the adaptive steering system
remains mechanically locked at a fixed
steering ratio. You may also notice a click
when you switch the vehicle on or after you
switch it off, as the lock disengages or
engages. Note:
If your vehicle loses electrical power
or detects a fault when you are driving, the
system automatically shuts down and you
retain normal steering function with a fixed
steering ratio. During this time, it is possible
that the steering wheel may not be straight
when the vehicle is driving straight ahead.
In addition, the driver may notice that the
steering wheel angle required to steer the
vehicle may be different.
Note: During parking maneuvers, the
adaptive steering system balances the driver
workload for various steering wheel inputs
and vehicle loading conditions. Under
extreme operating conditions the system
locking device may engage. This strategy
prevents overheating and permanent
damage to the adaptive steering system.
Typical steering and driving maneuvers
allow the system to cool and return to
normal operation.
