Following a Vehicle
WARNING:When following a vehicle in front of you, your
vehicle will not decelerate automatically to a stop, nor will your
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 adjusts to maintain a preset
gap distance. The distance setting is adjustable.
The lead vehicle graphic will be illuminated.
Your 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 your 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. You should take immediate action.
To help you to pass, the system may provide a small temporary
acceleration when the you switch on your left-turn indicator while
following a lead car.
Setting the Gap Distance
Note:It is your responsibility to select a gap appropriate to the driving
conditions.
You can decrease or increase the
distance between your vehicle and
the vehicle in front of you by
pressing theGAPcontrolupor
down. The selected gap will display
in the information display as shown by the bars in the graphic. Four gap
distance settings are available.

Disengaging Adaptive Cruise Control
Press the brake pedal or pressCNCLto disengage the system.
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.
You can override the set speed and gap distance by pressing the
accelerator pedal.
When you are overriding the system, the green indicator light
illuminates and the follow vehicle does not show 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 pressSETupward and
release.
•Increase or decrease the speed by holdingSETupward 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 pressingSETupward or downward.
The system may apply the brakes to slow your 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 you are aware of the set speed and
intend to return to it.
Press and releaseRES. Your 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 sounds and the automatic braking released if your
vehicle drops below this speed.
Hilly Condition Usage
Note:An audible alarm sounds and the system shuts 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, for
example driving in mountainous areas. Your vehicle needs additional
engine braking 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 will erase when you switch the system off.
Press and releaseOFFor turn off the ignition.

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 way.Clean 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 display.Wait 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 signals.Do not use the system in these
conditions because it may not
detect any vehicle ahead.

Cause Action
Swirling water, or snow or ice on
the surface of the road may
interfere with the radar signals.Do not use system in these
conditions because it may not
detect any vehicle ahead.
You are in a desert or remote area
with no other vehicles and no
roadside objects.Wait 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 Lights and Messages
The BLIS® and CTA systems
illuminate a yellow alert indicator in
the outside mirror on the side of
the vehicle the approaching vehicle
is coming from.
Note:The alert indicator dims when nighttime darkness is detected.
CTA also sounds an audible alarm and a message appears in the
information display indicating a vehicle is coming from the right or left.
CTA works with the reverse sensing system which sounds its own
audible alarm; see theParking Aidschapter.
System Sensors
WARNING:Just prior to the system recognizing a blocked
condition and alerting the driver, the number of missed objects
will increase. To help avoid injuries, NEVER use the BLIS® as a
replacement for using the side and rear view mirrors and looking over
your shoulder before changing lanes. BLIS® is not a replacement for
careful driving.
Note:It is possible to get a blockage warning with no blockage present;
this is rare and known as a false blockage warning. A false blocked
condition either self-corrects or clears after a key cycle.
The system uses radar sensors
which are located behind the
bumper fascia on each side of the
vehicle. Do not allow these areas to
become obstructed by mud, snow or
bumper stickers, as this can cause
degraded system performance.
Driving Aids239
2015 Flex(471)
Owners Guide gf, 1st Printing, October 2014

If the system detects a degraded performance condition, a blocked
sensor warning or low visibility warning will appear in the information
display and the alert indicator illuminates in the appropriate mirror(s).
The information display warning can be cleared but the alert indicator
remains illuminated.
When the blockage is removed, the system can be reset in two ways: 1)
when at least two objects are detected while driving, or 2) turn the
ignition key from on to off, then back on. If the blockage is still present
after the key cycle, the system senses again that it is blocked after
driving in traffic.
Reasons for messages being displayed
The radar surface is
dirty or obstructedClean the fascia area in front of the radar or
remove the obstruction.
The radar surface is
not dirty or obstructedDrive normally in traffic for a few minutes to
allow the radar to detect passing vehicles so it
can clear the blocked state.
Heavy rainfall/snowfall
interferes with the
radar signalsNo action required. The system automatically
resets to an unblocked state once the
rainfall/snowfall rate decreases or stops. Do
not use BLIS® and/or CTA in these conditions.
System Limitations
The BLIS® and CTA systems do have their limitations; situations such as
severe weather conditions or debris build-up on the sensor area may
limit vehicle detection.
The following are other situations that may limit the BLIS®:
•Certain maneuvering of vehicles entering and exiting the blind zone.
•Vehicles passing through the blind zone at very fast rates.
•When several vehicles forming a convoy pass through the blind zone.
The following are other situations that may limit the CTA system:
•Adjacently parked vehicles or objects obstructing the sensors.
•Approaching vehicles passing at speeds greater than 15 mph
(24 km/h).
•Driving in reverse faster than 3 mph (5 km/h).
•Backing out of an angled parking spot.

False Alerts
Note:If you connected a trailer to your vehicle the BLIS® system may
detect the trailer causing a false alert. To avoid false alerts you may want
to turn the BLIS off manually.
There may be certain instances when either the BLIS® or CTA systems
illuminate the alert indicator with no vehicle in the coverage zone; this is
known as a false alert. Some amount of false alerts are normal; they are
temporary and self-correct.
System Errors
If either system senses a problem with the left or right sensor, the
BLIS® indicator in the information display will illuminate and remain on.
Also,BLIND SPOT SYSTEM FAULTorCROSS TRAFFIC SYSTEM
FAULTmessage will appear. When problems that may cause the left or
right indicator not to illuminate, only the information display message
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 you switch off the Blind Spot Information System, you will not
receive alerts and the information display will display a system off
message. The yellow alert indicator in the outside mirror will also flash
twice. The system switches back on whenever you switch the ignition on.
You can also have one or both systems switched off permanently at an
authorized dealer. Once switched off, the system can only be switched
back on at an authorized dealer.
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.
Driving Aids241
2015 Flex(471)
Owners Guide gf, 1st Printing, October 2014
USA(fus)

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 sensitivity can be adjusted to one of three possible
settings by using the information display control. Refer to the
Information Displayschapter.
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.
