steering FORD TAURUS 2019 Service Manual

System Display
If you switch the system on in alert mode,
an overhead graphic of a vehicle with lane
markings appears in the information
display.
If you switch the system on in aid or alert
and aid mode, a separate white icon also
appears, or in some vehicles, arrows
appear with the lane markings.
When you switch the system off, the lane
marking graphics do not display.
When the system is on, the color of the
lane markings change to indicate the
system status.
Gray: Indicates that the system is
temporarily unable to provide a warning
or intervention on the indicated side. This
may be because:
•
Your vehicle is under the activation
speed.
• The direction indicator is active. •
Your vehicle is in a dynamic maneuver.
• The road has no or poor lane markings
in the camera field of view.
• The camera is obscured or unable to
detect the lane markings due to
environmental, traffic or vehicle
conditions. For example, significant sun
angles, shadows, snow, heavy rain or
fog, following a large vehicle that is
blocking or shadowing the lane or poor
headlamp illumination.
See Troubleshooting for additional
information.
Green: Indicates that the system is
available or ready to provide a warning or
intervention on the indicated side.
Yellow: Indicates that the system is
providing or has just provided a lane
keeping aid intervention.
Red: Indicates that the system is providing
or has just provided a lane keeping alert
warning.
The system can be temporarily suppressed
at any time by the following:
• Quick braking.
• Fast acceleration.
• Using the turn signal indicator.
• Evasive steering maneuver.
• Driving too close to the lane marking.
Troubleshooting Why is the feature not available (line markings are gray) when I can see the lane markings
on the road?
Your vehicle speed is outside the operational range of the feature.
The sun is shining directly into the camera lens.
A quick intentional lane change has occurred.

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 by an
authorized dealer. WARNING:
If the system detects
an error, you may not feel a difference in
the steering, however a serious condition
may exist. Obtain immediate service
from an authorized dealer, 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.
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
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.
COLLISION WARNING SYSTEM
(If Equipped)
PRINCIPLE OF OPERATION WARNING:
This system is
designed to be a supplementary driving
aid. It is not intended to replace the
driver ’s attention, and judgment, or the
need to apply the brakes. This system
does NOT activate the brakes
automatically. Failure to press the brake
pedal to activate the brakes may result
in a collision.

If a message regarding a blocked sensor
appears in the information display, the
radar signals from the sensor have been
obstructed. The sensors are located behind
a fascia cover near the driver side of the
lower grille. When the sensors are
obstructed, a vehicle ahead cannot be
detected and the collision warning system
does not function. The following table lists
possible causes and actions for this
message being displayed. 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 it is no longer obstructed
The surface of the radar in the grille is clean
but the message remains in the display
The collision warning system is temporarily
disabled. Collision warning should automat-ically reactivate a short time after the weather conditions improve
Heavy rain, spray, snow, or fog is interfering
with the radar signals
The collision warning system is temporarily
disabled. Collision warning should automat-ically reactivate 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
System Limitations WARNING: The collision warning
system ’s brake support can only help
reduce the speed at which a collision
occurs if the driver applies the vehicle ’s
brakes. The brake pedal must be pressed
just like any typical braking situation.
Due to the nature of radar technology,
there may be certain instances where
vehicles do not provide a collision warning.
These include:
• Stationary vehicles or vehicles moving
below 6 mph (10 km/h).
• Pedestrians or objects in the roadway.
• Oncoming vehicles in the same lane. •
Severe weather conditions (see
blocked sensor section).
• Debris build-up on the grille near the
headlamps (see blocked sensor
section).
• Small distance to vehicle ahead.
• Steering wheel and pedal movements
are large (very active driving style).
If the front end of the vehicle is hit or
damaged, the radar sensing zone may be
altered causing missed or false collision
warnings. See your authorized dealer to
have your collision warning radar checked
for proper coverage and operation.

Before Towing a Trailer
Practice turning, stopping and backing up
to get the feel of your vehicle-trailer
combination before starting on a trip.
When turning, make wider turns so the
trailer wheels clear curbs and other
obstacles.
When Towing a Trailer
•
Do not drive faster than 70 mph
(113 km/h) during the first 500 mi
(800 km).
• Do not make full-throttle starts.
• Check your hitch, electrical connections
and trailer wheel lug nuts thoroughly
after you have traveled 50 mi (80 km).
• When stopped in congested or heavy
traffic during hot weather, place the
gearshift in position P to aid engine and
transmission cooling and to help A/C
performance.
• Turn off the speed control with heavy
loads or in hilly terrain. The speed
control may turn off automatically
when you are towing on long, steep
grades.
• Shift to a lower gear when driving down
a long or steep hill. Do not apply the
brakes continuously, as they may
overheat and become less effective.
• If your transmission is equipped with a
Grade Assist or Tow/Haul feature, use
this feature when towing. This provides
engine braking and helps eliminate
excessive transmission shifting for
optimum fuel economy and
transmission cooling.
• Allow more distance for stopping with
a trailer attached. Anticipate stops and
brake gradually.
• Avoid parking on a grade. However, if
you must park on a grade:
1. Turn the steering wheel to point your vehicle tires away from traffic flow. 2. Set your vehicle parking brake.
3. Place the automatic transmission in
park (P).
4. Place wheel chocks in front and back of the trailer wheels. Chocks are not
included with your vehicle.
Launching or Retrieving a Boat or
Personal Watercraft (PWC)
Note: Disconnect the wiring to the trailer
before backing the trailer into the water.
Note: Reconnect the wiring to the trailer
after
removing the trailer from the water.
When backing down a ramp during boat
launching or retrieval:
• Do not allow the static water level to
rise above the bottom edge of the rear
bumper.
• Do not allow waves to break higher
than
6 in (15 cm) above the bottom
edge of the rear bumper.
Exceeding these limits may allow water to
enter vehicle components:
• Causing internal damage to the
components.
• Affecting drivability, emissions, and
reliability.
Replace the rear axle lubricant anytime
the rear axle has been submerged in water.
Water may have contaminated the rear
axle lubricant, which is not normally
checked or changed unless a leak is
suspected or other axle repair is required.

•
Transmissions give their best fuel
economy when operated in the top
cruise gear and with steady pressure
on the gas pedal.
• Four-wheel-drive operation (if
equipped) is less fuel efficient than
two-wheel-drive operation.
• Close the windows for high-speed
driving.
DRIVING THROUGH WATER WARNING: Do not drive through
flowing or deep water as you may lose
control of your vehicle.
Note: Driving through standing water can
cause vehicle damage.
Note: Engine damage can occur if water
enters the air filter.
Before driving through standing water,
check the depth. Never drive through water
that is higher than the bottom of the front
rocker area of your vehicle. When driving through standing water, drive
very slowly and do not stop your vehicle.
Your brake performance and traction may
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.
• Check that the horn works.
• Check that the exterior lights work.
• Turn the steering wheel to check that
the steering power assist works.
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.
