2020 FORD EXPEDITION power steering

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.
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.
Roll Stability Control
The system 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.

STEERING
Electric Power Steering 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.
Your vehicle has an electric power steering
system, there is no fluid reservoir, no
maintenance is required.
If your vehicle loses electrical power while
you are driving, electric power steering
assistance is lost. The steering system still
operates and you can steer your vehicle
manually. Manually steering your vehicle
requires more effort.
256
Expedition (TB8) Canada/United States of America, enUSA, Edition date: 201907, Third-Printing- Driving Aids

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.
Steering Tips
If the steering wanders or pulls, check for:
•
Correct tire pressures.
• 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.
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. Additionally, 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. PRE-COLLISION ASSIST 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. WARNING:
The system does not
detect vehicles that are driving in a
different direction, pedestrians at night,
cyclists or animals. Apply the brakes
when necessary. Failure to follow this
instruction could result in the loss of
control of your vehicle, personal injury or
death. WARNING:
The system does not
operate during hard acceleration or
steering. Failure to take care may lead
to a crash or personal injury. WARNING: The system may fail or
operate with reduced function during
cold and severe weather conditions.
Snow, ice, rain, spray and fog can
adversely affect the system. Keep the
front camera and radar free of snow and
ice. Failure to take care may result in the
loss of control of your vehicle, serious
personal injury or death. WARNING:
Some situations and
objects prevent hazard detection. For

Radar Troubleshooting (If Equipped)
Action
Cause
Clean the grille surface in front of the radaror remove the object causing the obstruc- tion.
The surface of the radar in the grille is dirty
or obstructed in some way.
Wait a short time. It may take several
minutes for the radar to detect that there is no obstruction.
The surface of the radar in the grille is clean
but the message remains in the display screen.
The pre-collision assist system is tempor-
arily disabled. Pre-collision assist automat- ically reactivates a short time after the weather conditions improve.
Heavy rain, spray, snow or fog is interfering
with the radar signals.
The pre-collision assist system is tempor-
arily disabled. Pre-collision assist automat- ically reactivates a short time after the weather conditions improve.
Swirling water or snow or ice on the surface
of the road may interfere with the radar signals.
Contact an authorized dealer to have theradar checked for proper coverage and operation.
Radar is out of alignment due to a front-
end impact.
Note: Proper system operation requires a
clear view of the road by the camera. Have
any windshield damage in the area of the
camera's field of view repaired.
Note: 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 detections. Contact an
authorized dealer to have the radar checked
for proper coverage and operation.
Note: If your vehicle detects excessive heat
at the camera or a potential misalignment
condition, a message could display in the
information display indicating temporary
sensor unavailability. This message
deactivates automatically when operational
conditions are correct. For example, when
the ambient temperature around the sensor
decreases or the sensor automatically
recalibrates successfully. DRIVE CONTROL
