2013 FORD FLEX brake

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.
Changing the Set Speed
There are three ways to change the set speed:
•Accelerate or brake to the desired speed and press SET upward and
release.
•Increase or decrease the speed by holding SET upward or downward
until the desired set speed is shown on the information display. The
vehicle speed will gradually change to the selected speed.
•Increase or decrease the speed in increments of 1 mph (2 km/h) by
briefly pressing the SET upward or downward.
The system may apply the brakes to slow the vehicle down to the new
set speed. The set speed will display continuously in the information
display while the system is active.

Resuming the Set Speed
Note:Resume should only be used if the driver is aware of the set speed
and intends to return to it.
Press and release RES/CNCL. The vehicle will return to the previously
set speed. The set speed will display continuously in the information
display while the system is active.
Low Speed Automatic Cancellation
The system is not functional at vehicle speeds below 16 mph (26 km/h).
An audible alarm will sound and the automatic braking will be released if
the vehicle drops below this speed.
Hilly Condition Usage
Note:An audible alarm will sound and the system will shut down if it is
applying brakes for an extended period of time. This allows the brakes to
cool down. The system will function normally again when the brakes
have cooled down.
You should select a lower gear position when the system is active in
situations such as prolonged downhill driving on steep grades (i.e.,
driving in mountainous areas). Additional engine braking is needed in
these situations to reduce the load on the vehicle’s regular brake system
to prevent them from overheating.
Switching Off Adaptive Cruise Control
Note:The set speed memory is erased when you turn off the system.
Press and release OFF or turn off the ignition.

Detection Issues
The radar sensor has a limited field of vision. It may not detect vehicles at
all or detect a vehicle later than expected in some situations. The lead
vehicle graphic will not illuminate if a vehicle is not detected in front of you.
Detection issues can occur:
A. When driving on a different line
than the vehicle in front.
B. With vehicles that edge into your
lane. These vehicles can only be
detected once they have moved fully
into your lane.
C. There may be issues with the
detection of vehicles in front when
driving into and coming out of a
bend or curve in the road.
In these cases the system may brake late or unexpectedly. The driver
should stay alert and intervene when necessary.
If the front end of the vehicle is hit or damaged, the radar sensing zone may
be altered causing missed or false vehicle detections. See your authorized
dealer to have the radar checked for proper coverage and operation.
Adaptive Cruise Control Not Available
Several conditions exist which can cause the system to deactivate or
prevent the system from activating when requested. These conditions
include:
•a blocked sensor
•high brake temperature
•a failure in the system or a related system.

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.
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.

System Errors
If either system senses a problem with the left or right sensor, the BLIS
indicator illuminates and remains on andBLIND SPOT SYSTEM
FAULTorCROSS TRAFFIC SYSTEM FAULTappears in the
information display. When problems that may cause the left or right
indicator not to illuminate, only the information display faults appear.
Switching the Systems Off and On
One or both systems can be switched off temporarily by using the
information display control; refer to theInformation Displaychapter.
When the BLISis switched off, the driver does not receive alerts and
the information display shows BLIND SPOT SYS OFF and/or CTA
SYSTEM OFF. The system switches back on whenever the ignition is
switched on.
One or both systems can also be switched off permanently at your
authorized dealer. Once switched off, switching it back on must also be
done at the dealership. When switched off, the information display shows
BLIND SPOT DISABLED and/or CTA DISABLED.
COLLISION WARNING SYSTEM (IF EQUIPPED)
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.
WARNING:The collision warning system with brake support
cannot help prevent all collisions. Do not rely on this system to
replace driver judgment and the need to maintain distance and speed.
Note:The system does not detect, warn or respond to potential
collisions with vehicles to the rear or sides of the vehicle.
Note:The collision warning system is active at speeds above
approximately 5 mph (8 km/h).

This system is designed to alert the
driver of certain collision risks. A
radar detects if your vehicle is rapidly
approaching another vehicle traveling
in the same direction as yours.
If it is, a red warning light
illuminates and an audible warning
chime sounds.
The brake support system assists the driver in reducing the collision speed
by charging the brakes. If the risk of collision further increases after the
warning light illuminates, the brake support prepares the brake system for
rapid braking. This may be apparent to the driver. The system does not
automatically activate the brakes but, if the brake pedal is pressed, full force
braking is applied even if the brake pedal is lightly pressed.
Using the Collision Warning System
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.
The warning system and chime can be turned on and off separately; the
warning system sensitivity can be adjusted to one of three possible
settings by using the information display control. Refer to the
Information Displayschapter.
Note:If the system cannot be turned off in a vehicle equipped with
MyKey, refer to theMyKeychapter.
Note:If collision warnings are perceived as being too frequent or
disturbing then the warning sensitivity can be reduced, though the
manufacturer recommends using the highest sensitivity setting where
possible. Setting lower sensitivity would lead to fewer and later system
warnings. Refer to theInformation Displayschapter for instructions on
reducing the sensitivity.
