Ford Taurus (2018 year). Manual — part 46

The warning system has two stages. First,
the system issues a temporary warning
that you need to take a rest. This message
only appears for a short time. If the system
detects further reduction in driving
alertness, it may issue another warning
that remains in the information display for
a longer time. You can press OK on the
steering wheel control to clear the warning.

System Display

When active, the system runs
automatically in the background and only
issues a warning if required. You can view
the status at any time using the
information display. See General
Information

(page 88).

The alertness level is shown by six steps
in a colored bar.

E131358

The current assessment of your alertness
is within a typical range.

E131359

The current assessment of your alertness
indicates that you should rest as soon as
safely possible.

The status bar travels from left to right as
the calculated alertness level decreases.
As the meter approaches the rest icon, the
color turns from green to yellow to red.

The yellow position indicates the first
warning is active and the red position
indicates the second warning is active.

Note:

If you have recently received a

warning, you should consider resting, even
if the current assessment is within the
typical range.

Note:

If the camera sensor cannot track the

road lane markings, or if your vehicle speed
drops below approximately 40 mph
(64 km/h), the alertness level changes to
grey for a short time and the information
display informs you that the system is
unavailable.

Resetting the System

You can reset the system by either:

•

Switching the ignition off and on.

•

Stopping the vehicle and then opening
and closing the driver’s door.

LANE KEEPING SYSTEM

(If

Equipped)

WARNINGS

The system is designed to aid the
driver. It is not intended to replace
your attention and judgment. You are

still responsible to drive with due care and
attention.

Always drive with due care and
attention when using and operating
the controls and features on your

vehicle.

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.

WARNINGS

In cold and severe weather
conditions the system may not
function. Rain, snow and spray can

all limit sensor performance.

The system will not operate if the
sensor cannot track the road lane
markings.

The sensor may incorrectly track lane
markings as other structures or
objects. This can result in a false or

missed warning.

The system may not operate
properly if the sensor is blocked.
Keep the windshield free from

obstruction.

If damage occurs in the immediate
area surrounding the sensor, have
your vehicle checked as soon as

possible.

Note:

The system works above 40 mph

(64 km/h).

Note:

The system works as long as the

camera can detect one lane marking.

Note:

When Aid or both modes are selected

and the system detects no steering activity
for a short period, the system alerts you to
put your hands on the steering wheel. The
system may detect a light grip or touch on
the steering wheel as hands off driving.

E249505

The system notifies you to stay in your lane
through the steering system and the
instrument cluster display when the front
camera detects an unintentional drift out
of your lane is likely to occur. The system
automatically detects and tracks the road
lane markings using a camera mounted
behind the interior rear view mirror.

Switching the System On and Off

Note:

The system on or off setting is stored

until it is manually changed, unless a
MyKey™ is detected. If the system detects
a MyKey™ it defaults to on and the mode
is set to Alert.

Note:

If a MyKey™ is detected, pressing the

button will not affect the on or off status of
the system.

E173233

Press the button located on the
center console to switch the
system on or off.

System Display

E151660

When you switch on the system, an
overhead graphic of a vehicle with lane
markings will display in the information
display. If you select aid mode when you
switch on the system, a separate white
icon will also appear or in some vehicles
arrows will display with the lane markings.

When you switch off the system, the lane
marking graphics will not display.

While the system is on, the color of the
lane markings will change to indicate the
system status.

Gray: Indicates that the system is
temporarily unable to provide a warning
or intervention on the indicated side(s).
This may be because:

•

Your vehicle is under the activation
speed.

•

The turn 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 conditions (significant
sun angles, shadows, snow, heavy rain
or fog), traffic conditions (following a
large vehicle that is blocking or
shadowing the lane), or vehicle
conditions (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(s).

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.

Troubleshooting

Why is the feature not available (line markings are gray) when I can see the lane markings

on the road?
