2013 FORD EXPLORER warning

Following a Vehicle
WARNING:When following a vehicle in front of you, the vehicle
will not decelerate automatically to a stop, nor will the vehicle
always decelerate quickly enough to avoid a collision without driver
intervention. Always apply the brakes when necessary. Failing to do so
may result in a collision, serious injury or death.
WARNING:Adaptive cruise control only warns of vehicles
detected by the radar sensor. In some cases there may be no
warning or the warning may be delayed. The driver should always apply
the brakes when necessary. Failing to do so may result in a collision,
serious injury or death.
Note:The brakes may emit a sound when they are being modulated by
the adaptive cruise control system.
When a vehicle ahead of you enters the same lane or a slower vehicle is
ahead in the same lane, the vehicle speed will adjust automatically to
maintain a preset gap distance. The distance setting is adjustable.
The lead vehicle graphic will be illuminated.
The vehicle will maintain a constant distance between the vehicle ahead
until:
•the vehicle in front of you accelerates to a speed above the set speed
•the vehicle in front of you moves out of your lane or out of view
•the vehicle speed falls below 16 mph (26 km/h)
•a new gap distance is set.
The vehicle brakes will be automatically applied to slow the vehicle to
maintain a safe distance from the vehicle in front. The maximum braking
which is applied by the system is limited and can be overridden by the
driver applying the brakes.
If the system predicts that its maximum braking level will not be
sufficient, an audible warning will sound while the system continues to
brake. This is accompanied by a heads-up display; a red warning bar
illuminating on the windshield. The driver should take immediate action.

Setting the Gap Distance
Note:It is the driver’s responsibility to select a gap appropriate to the
driving conditions.
The distance between your vehicle
and the vehicle in front of you can
be decreased or increased by
pressing the GAP control up or
down. The selected gap will be
displayed in the message center as shown by the bars in the graphic.
Four gap distance settings are available.

Each time the vehicle is restarted, the last chosen gap for the current
driver will be automatically selected.
Disengaging Adaptive Cruise Control
Press the brake pedal or press CNCL to disengage the system. The last
set speed will be displayed with a strikethrough.
Disengaging the system will not erase your previous set speed.
Overriding Adaptive Cruise Control
WARNING:Whenever the driver is overriding the ACC by
pressing the accelerator pedal, the ACC will not automatically
apply the brakes to maintain separation from any vehicle ahead.
The set speed and gap distance can be overridden by pressing the
accelerator pedal.
When the driver is overriding the system, the green indicator
light is illuminated, and the follow vehicle is not shown in the
information display. The system will resume operation when you
release the accelerator pedal. The vehicle speed will decrease to the set
speed, or a lower speed if following a slower vehicle.

Blocked Sensor
WARNING:Do not use ACC when towing a trailer with brake
controls. Aftermarket trailer brakes will not function properly
when ACC is activated because the brakes are electronically controlled.
Failing to do so may result in loss of vehicle control, which could result
in serious injury.
WARNING:Do not use tires sizes other than those
recommended because this can affect the normal operation of
ACC. Failing to do so may result in a loss of vehicle control, which
could result in serious injury.
A message regarding a blocked
sensor is displayed if the radar
signals from the sensor have been
obstructed. The sensor is located
behind a fascia cover near the driver
side of the lower grille. A vehicle
ahead cannot be detected and the
system will not function when the
radar signals are obstructed. The
following table lists possible causes
and actions for this message being
displayed.
Cause Action
The surface of the radar in the
grille is dirty or obstructed in
some wayClean the grille surface in front of
the radar or remove the object
causing the obstruction
The surface of the radar in the
grille is clean but the message
remains in the displayWait a short time. It may take
several minutes for the radar to
detect that it is no longer
obstructed
Heavy rain or snow is interfering
with the radar signalsDo not use ACC in these condition
because it may not detect, warn,
or respond to potential collisions.

Cause Action
Swirling water, or snow or ice on
the surface of the road may
interfere with the radar signalsDo not use ACC in these condition
because it may not detect, warn,
or respond to potential collisions.
Desert / remote area with no other
vehicles and no roadside objectsWait a short time or switch to
normal cruise control.
Due to the nature of radar technology, it is possible to get a blockage
warning and not be blocked. This can happen, for example, when driving
in sparse rural or desert environments. A false blocked condition will
either self clear or clear after a key cycle.
Switching to Normal Cruise Control
WARNING:Normal cruise control will not brake due to slower
vehicles. Always be aware of which mode is selected and apply
the brakes when necessary.
You can manually change from adaptive cruise control to normal cruise
control through the information display.
The cruise control indicator light will replace the adaptive
cruise control indicator light if normal cruise control is selected.
The gap setting will not be displayed, the system will not
automatically respond to lead vehicles and automatic braking will not be
activated. The system will default to adaptive cruise control when the
engine is started.

intended to replace the driver’s attention and judgment. The
driver is still responsible to drive with due care and attention.
The system detects unintentional drifting toward the outside of the lane
and alerts and/or aids the driver to stay in the lane through the steering
system and instrument cluster display. The system automatically detects
and tracks the road lane markings using a camera that is mounted behind
the interior rear view mirror.
Note:The system needs to be activated by the driver at each key cycle.
Note:The system works above 40 mph (64 km/h).
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:When Aid mode is on and the driver’s hands are off the steering
wheel for a short continuous period of time, the system alerts the driver
to put their hands on the steering wheel. The system may detect a light
grip/touch on the steering wheel as hands off driving. SeeSystem
settings.
