PRINCIPLE OF OPERATION
WARNINGS
Vehicle modifications involving
braking system, aftermarket roof
racks, suspension, steering system,
tire construction and wheel and tire size
may change the handling characteristics
of your vehicle and may adversely affect
the performance of the electronic stability
control system. In addition, installing any
stereo loudspeakers may interfere with
and adversely affect the electronic stability
control system. Install any aftermarket
stereo loudspeaker as far as possible from
the front center console, the tunnel, and
the front seats in order to minimize the risk
of interfering with the electronic stability
control sensors. Reducing the
effectiveness of the electronic stability
control system could lead to an increased
risk of loss of vehicle control, vehicle
rollover, personal injury and death. Remember that even advanced
technology cannot defy the laws of
physics. It’
s always possible to lose
control of a vehicle due to inappropriate
driver input for the conditions. Aggressive
driving on any road condition can cause
you to lose control of your vehicle
increasing the risk of personal injury or
property damage. Activation of the
electronic stability control system is an
indication that at least some of the tires
have exceeded their ability to grip the road;
this could reduce the operator ’s ability to
control the vehicle potentially resulting in
a loss of vehicle control, vehicle rollover,
personal injury and death. If your electronic
stability control system activates, SLOW
DOWN. The system automatically turns on each
time you switch the ignition on. If a fault occurs in either the stability
control or the traction control system, you
may experience the following conditions:
•
The stability and traction control light
illuminates steadily.
• The stability control and traction
control systems do not enhance your
vehicle's ability to maintain traction of
the wheels.
If a driving condition activates either the
stability control or the traction control
system you may experience the following
conditions:
• The stability and traction control light
flashes.
• Your vehicle slows down.
• Reduced engine power.
• A vibration in the brake pedal.
• The brake pedal is stiffer than usual.
• If the driving condition is severe and
your foot is not on the brake, the brake
pedal may move as the system applies
higher brake force.
The stability control system has several
features built into it to help you maintain
control of your vehicle:
Electronic Stability Control
The system enhances your vehicle ’s ability
to prevent skids or lateral slides by
applying brakes to one or more of the
wheels individually and, if necessary,
reducing engine power.
Roll Stability Control
The system enhances your vehicle ’s ability
to prevent rollovers by detecting your
vehicle ’s roll motion and the rate at which
it changes by applying the brakes to one
or more wheels individually.

Traction Control
The system enhances your vehicle
’s ability
to maintain traction of the wheels by
detecting and controlling wheel spin. See
Using Traction Control (page 177). Vehicle without stability control

PRINCIPLE OF OPERATION
WARNINGS
To help avoid personal injury, always
use caution when in reverse (R) and
when using the sensing system.
The system may not detect objects
with surfaces that absorb reflection.
Always drive with due care and
attention. Failure to take care may result
in a crash. Traffic control systems, inclement
weather, air brakes, external motors
and fans may affect the correct
operation of the sensing system.This may
cause reduced performance or false alerts. The system may not detect small or
moving objects, particularly those
close to the ground.
Note:
If your vehicle is equipped with
MyKey ™, the sensing system cannot be
turned off when a MyKey ™ is present. See
Principle of Operation (page 57).
Note: Keep the sensors, located on the
bumper or fascia, free from snow, ice and
large accumulations of dirt. If the sensors
are covered, the system ’s accuracy can be
affected. Do not clean the sensors with
sharp objects.
Note: If your vehicle sustains damage to
the bumper or fascia, leaving it misaligned
or bent, the sensing zone may be altered
causing inaccurate measurement of
obstacles or false alerts.
Note: Certain add-on devices installed
around the bumper or fascia may create
false alerts. For example, large trailer
hitches, bike or surfboard racks, license plate
brackets, bumper covers or any other device
that may block the normal detection zone
of the system. Remove the add-on device
to prevent false alerts. Note:
When a trailer is connected to your
vehicle, the rear parking aid may detect the
trailer and therefore provide an alert. Disable
the rear parking aid when a trailer is
connected to prevent the alert.
The sensing system warns the driver of
obstacles within a certain range of your
vehicle. The system turns on automatically
whenever you switch the ignition on.
The system can be switched off through
the information display menu or from the
pop-up message that appears once you
shift the transmission into reverse (R). See
General Information
(page 97).
If a fault is present in the system, a warning
message appears in the information
display. See
Information Messages
(page 105).
REAR PARKING AID
The rear sensors are only active when the
transmission is in reverse (R). As your
vehicle moves closer to the obstacle, the
rate of the audible warning increases.
When the obstacle is less than
12 in
(30 cm) away, the warning sounds
continuously. If the system detects a
stationary or receding object farther than
12 in (30 cm)
from the corners of the
bumper, the tone sounds for only three
seconds. Once the system detects an
object approaching, the warning sounds
again.

PRINCIPLE OF OPERATION
Cruise control lets you maintain a set
speed without keeping your foot on the
accelerator pedal. You can use cruise
control when your vehicle speed is greater
than 20 mph (30 km/h).
USING CRUISE CONTROL WARNINGS
Do not use cruise control on winding
roads, in heavy traffic or when the
road surface is slippery. This could
result in loss of vehicle control, serious
injury or death. When you are going downhill, your
vehicle speed could increase above
the set speed. The system does not
apply the brakes. Note:
Cruise control disengages if the
vehicle speed decreases more than 10 mph
(16 km/h) below the set speed when driving
uphill. The cruise controls are on the steering
wheel.

audible warning sounds and a message
appears in the information display.
Automatic braking releases.
The system does not operate below
12 mph (20 km/h)
.
Automatic cancellation can also occur if:
• The tires lose traction.
• The engine speed is too low.
• You apply the parking brake. Hilly Condition Usage
Note:
An audible alarm sounds and the
system shuts down if it applies brakes for
an extended period of time. This allows the
brakes to cool. The system functions
normally again after the brakes cool.
Select a lower gear when the system is
active in situations such as prolonged
downhill driving on steep grades, for
example in mountainous areas. The
system needs additional engine braking in
these situations to reduce the load on the
vehicle ’s regular brake system to prevent
it from overheating.
Switching Adaptive Cruise Control
Off
Note: You erase the set speed and gap
setting when you switch the system off.
Press
OFF when the system is in standby
mode, or switch the ignition off.
Detection Issues WARNINGS
On rare occasions, detection issues
can occur due to the road
infrastructures, for example bridges,
tunnels and safety barriers. In these cases,
the system may brake late or
unexpectedly. At all times, you are
responsible for controlling your vehicle,
supervising the system and intervening, if
required. If the system malfunctions, have your
vehicle checked as soon as possible.
The radar sensor has a limited field of view.
It may not detect vehicles at all or detect
a vehicle later than expected in some
situations. The lead vehicle graphic does
not illuminate if the system does not
detect a vehicle in front of you.
193
Flex (TP3) , enUSA, Edition date: 201801, Second Printing Cruise Control

System Sensor Blockage
The system uses radar sensors that are
located behind the bumper fascia on each
side of your vehicle. Any dirt, mud and
snow in front of the sensors and/or driving
in heavy rain can cause system
degradation. Also, other types of
obstructions in front of the sensor can
cause system degradation. This is referred
to as a
‘blocked ’ condition.
Note: Do not apply bumper stickers and/or
repair compound to these areas, this can
cause degraded system performance.
If the system detects a degraded
performance condition, a message warning
of a blocked sensor will appear in the
information display. Also the system alert
indicators will remain ON and the system
will no longer provide any vehicle warnings.
You can clear the information display
warning but the alert indicators will remain
illuminated.
A "blocked" condition can be cleared in
two ways:
• After the blockage in front of the
sensors is removed or the
rainfall/snowfall rate decreases or
stops, drive for a few minutes in traffic
to allow the sensors to detect passing
vehicles.
• By cycling the ignition from ON to OFF
and then back ON. Note:
When towing a trailer, the sensors
may detect the trailer thus causing a false
alert. It may be desirable to turn the Blind
Spot Information System off if the false
alerts become annoying.
System Errors
If the system senses a problem with the
left or right sensor, the telltale will
illuminate and a message will appear in
the information display. See Information
Messages (page 105).
System Limitations
The system does have its limitations;
situations such as severe weather
conditions or debris build-up on the sensor
may limit vehicle detection.
The following are other situations that may
limit the system:
• 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.
Switching the System Off and On
You can temporarily switch the Blind Spot
Information System off in the information
display. See
General Information (page
97). When the Blind Spot Information
System switches off, you will not receive
alerts and the information display shows
a system off message. The telltale in the
cluster also illuminates. When you switch
the Blind Spot Information System on or
off, the alert indicators flash twice.
Note: The system switches back on every
time you start your vehicle.
197

Information System (page 196). If the
Blind Spot Information System is blocked,
Cross Traffic Alert is also blocked. A
corresponding message appears in the
information display as soon as you shift
the transmission into reverse (R).
System Limitations
Cross Traffic Alert has its limitations;
situations such as severe weather
conditions or debris build-up on the sensor
area may limit vehicle detection.
The system detects approaching vehicles
from up to
45 ft (14 m) away, though
coverage decreases when the sensors are
blocked. Reversing slowly helps increase
the coverage area and effectiveness.
The following are other situations that may
limit the Cross Traffic Alert performance:
• Stationary or slow moving vehicles.
• Pedestrians or objects in the roadway.
• Oncoming vehicles in the same lame.
• Severe weather conditions.
• Debris build-up near or around the
sensor(s).
• Small distance to the vehicle ahead.
• Adjacently parking 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.
If the rear end of the vehicle is hit or
damaged, the radar sensing zone may be
altered causing missed or false collision
warnings. See your authorized dealer to
have your collision warning radar checked
for proper coverage and operation. False Alerts
Note:
When towing a trailer, the sensors
may detect the trailer thus causing a false
alert. It may be desirable to turn the Blind
Spot Information System off if the false
alerts become annoying.
There may be certain instances when there
is a false alert by the Cross Traffic Alert
system that illuminates the alert indicator
with no vehicle in the coverage zone. Some
amount of false alerts are normal; they are
temporary and self-correct.
System Errors
If Cross Traffic Alert senses a problem with
the left or right sensor a message will
appear in the information display. See
Information Messages
(page 105).
Switching the System Off and On
You can temporarily switch Cross Traffic
Alert off in the information display. See
Information Messages (page 105). When
you switch Cross Traffic Alert off, you will
not receive alerts and the information
display will display a system off message.
Note: The Cross Traffic Alert switches on
whenever the ignition is switched on and
ready to provide appropriate alerts when
the transmission is in reverse (R). Cross
Traffic Alert will not remember the last
selected on or off setting.
You can also have Cross Traffic Alert
switched off permanently at an authorized
dealer. Once switched off permanently,
the system can only be switched back on
at an authorized dealer.

STEERING
Electric Power Steering
WARNINGS
The electric power steering system
has diagnostic checks that
continuously monitor the system. If
a fault is detected, a message displays in
the information display. Stop your vehicle
as soon as it is safe to do so. Switch the
ignition off. After at least 10 seconds,
switch the ignition on and watch the
information display for a steering system
warning message. If a steering system
warning message returns, have the system
checked by an authorized dealer. If the system detects an error, you
may not feel a difference in the
steering, however a serious condition
may exist. Obtain immediate service from
an authorized dealer, failure to do so may
result in loss of steering control. Your vehicle has an electric power steering
system. There is no fluid reservoir. No
maintenance is required.
If your vehicle loses electrical power while
you are driving, electric power steering
assistance is lost. The steering system still
operates and you can steer your vehicle
manually. Manually steering your vehicle
requires more effort.
Extreme continuous steering may increase
the effort required for you to steer your
vehicle. This increased effort prevents
overheating and permanent damage to
the steering system. You do not lose the
ability to steer your vehicle manually.
Typical steering and driving maneuvers
allow the system to cool and return to
normal operation. Steering Tips
If the steering wanders or pulls, check for:
•
Correct tire pressures.
• Uneven tire wear.
• Loose or worn suspension
components.
• Loose or worn steering components.
• Improper vehicle alignment.
Note: A high crown in the road or high
crosswinds may also make the steering
seem to wander or pull.
Adaptive Learning
The electronic power steering system
adaptive learning helps correct road
irregularities and improves overall handling
and steering feel. It communicates with
the brake system to help operate
advanced stability control and accident
avoidance systems. Additionally, whenever
the battery is disconnected or a new
battery installed, you must drive your
vehicle a short distance before the system
relearns the strategy and reactivates all
systems.
COLLISION WARNING SYSTEM
(If Equipped)
PRINCIPLE OF OPERATION WARNINGS
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.

TRAILER SWAY CONTROL (If
Equipped) WARNING
Turning off trailer sway control
increases the risk of loss of vehicle
control, serious injury or death. Ford
does not recommend disabling this feature
except in situations where speed reduction
may be detrimental (such as hill climbing),
the driver has significant trailer towing
experience, and can control trailer sway
and maintain safe operation. Note:
This feature does not prevent trailer
sway, but reduces it when it begins.
Note: This feature cannot stop all trailers
from swaying.
Note: In some cases, if your vehicle speed
is too high, the system may turn on multiple
times, gradually reducing your vehicle speed.
The system applies the brakes to the
individual wheels and reduces engine
torque to aid vehicle stability. If the trailer
begins to sway, the stability control
warning lamp flashes and a message
appears in the information display. See
Information Messages (page 105). Slow
your vehicle down, pull safely to the side
of the road and check for correct load
distribution. See
Load Carrying (page
204).
You can switch this feature off in the
information display. When you switch the
ignition on, the system automatically turns
on. RECOMMENDED TOWING
WEIGHTS
Note:
Do not exceed the trailer
weight for your vehicle
configuration listed in the chart
below.
Note: Make sure to take into
consideration trailer frontal area.
Do not exceed 20 ft² (1.86 m²) if
your vehicle can tow a class I
trailer, or 40 ft² (3.72 m²) if your
vehicle can tow a class III trailer.
Note: For high altitude operation,
reduce the gross combined weight
by 2% per
1,000 ft (300 m)
starting at the 1,000 ft (300 m)
elevation point.
Note: Certain states require
electric trailer brakes for trailers
over a specified weight. Check
state regulations for this specified
weight. The maximum trailer
weights listed may be limited to
this specified weight, as the
