FORD 2015 Explorer - Manual (Page 249)

DRIVER ALERT (IF EQUIPPED)
WARNING: The driver alert system is designed to aid you. It is
not intended to replace your attention and judgment. You are still
responsible to drive with due care and attention.
Note: The system will store the on/off setting in the information display
menu through ignition cycles.
Note: If enabled in the menu, the system will be active above 40 mph
(64 km/h). When below the activation speed the driver alert system
display will inform you that the system is unavailable.
Note: The system works as long as one lane marking can be detected by
the camera.
Note: If the camera is blocked or if the windshield is damaged, the
system may not function.
Note: The system may not be available in poor weather or other low
visibility conditions.
The system automatically monitors your driving behavior using various
inputs including the front camera sensor.
If the system detects that your driving alertness is reduced below a
certain threshold, the system will alert you using a chime and a message
in the cluster display
Switching the System On and Off
You may switch the system on or off through the Information Display.
Refer to the Information Displays chapter. The system on or off setting
is stored and will use your last setting the next time the vehicle is
started.
System Warnings
Note: The system will not issue warnings below approximately 40 mph
(64 km/h).
The warning system is in two stages. At first the system issues a
temporary warning that you need to take a rest. This message will only
appear for a short time. If the system detects further reduction in driving
alertness, another warning may be issued which will remain in the
information display for a longer time. Press OK on the steering wheel
control to clear the warning.
