2022 FORD F-550 power 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.

WHAT IS DRIVE MODE
CONTROL
Your vehicle has various drive modes that
you can select for different driving
conditions. Depending on the drive mode
that you select, the system adjusts various
vehicle settings.
HOW DOES DRIVE MODE
CONTROL WORK
Drive mode control adjusts your vehicle
configuration for each mode you select.
Changing the drive mode adjusts the
steering effort and feel of the steering
system.
The stability and traction control assist
your vehicle control in adverse conditions
or high-performance driving.
Throttle control enhances the powertrain
response, transmission controls become
optimized with shift schedules, and
four-wheel drive settings are optimized
and tuned to each mode.
Changing the drive mode can engage or
disengage the electronic locking
differentials.
Changing the drive mode changes the
four-wheel drive mode to the default
setting for the selected drive mode.
Note:
The system has diagnostic checks
that continuously monitor the system for
proper operation. If a mode is unavailable
due to a system fault, the drive mode
system defaults to normal. When the
system defaults to normal, the driveline
settings remain the same as prior to the
system fault. Note:
The system reverts to the normal
mode each time you start your vehicle. At
startup the system also displays a prompt
on the instrument cluster display that gives
you the option to return to the previously
selected drive mode during the last ignition
cycle. If you select yes, the system returns
to the last selected drive mode and the
default driveline settings associated with
that mode. If you select no, the system
remains in normal mode and the driveline
settings remain the same as selected in the
prior ignition cycle. If you do not select yes
or no, the system stays in normal mode and
the driveline settings remain the same as
selected in the prior ignition cycle.
SELECTING A DRIVE MODE To change the drive mode setting, press
the drive mode button. The drive mode
selection menu appears in the instrument
cluster and allows you to select through
the available drive modes.

When driving through standing water, drive
very slowly and do not stop your vehicle.
Your brake performance and traction could
be limited. After driving through water and
as soon as it is safe to do so:
•
Lightly press the brake pedal to dry the
brakes and to check that they work.
• Turn the steering wheel to check that
the steering power assist works.
Check the function of the following:
• Horn
• Exterior lights
FLOOR MATS WARNING: Use a floor mat
designed to fit the footwell of your
vehicle that does not obstruct the pedal
area. Failure to follow this instruction
could result in the loss of control of your
vehicle, personal injury or death. WARNING:
Pedals that cannot
move freely can cause loss of vehicle
control and increase the risk of serious
personal injury. WARNING:
Secure the floor mat
to both retention devices so that it
cannot slip out of position and interfere
with the pedals. Failure to follow this
instruction could result in the loss of
control of your vehicle, personal injury or
death. WARNING: Do not place additional
floor mats or any other covering on top
of the original floor mats. This could
result in the floor mat interfering with the
operation of the pedals. Failure to follow
this instruction could result in the loss of
control of your vehicle, personal injury or
death. WARNING:
Always make sure that
objects cannot fall into the driver foot
well while your vehicle is moving. Objects
that are loose can become trapped
under the pedals causing a loss of
vehicle control. To install floor mats that have eyelets,
position the floor mat eyelet over the
retention post and press down to lock in
position. Repeat for all eyelets on the floor
mat.
To remove the floor mats, reverse the
installation procedure.
