Overriding the System
WARNING
If you override the system by pressing
the accelerator pedal, it does not
automatically apply the brakes to
maintain a gap from any vehicle ahead. You can override the set speed and gap by
pressing the accelerator pedal.
When you override the system,
the green indicator light
illuminates and the lead vehicle
graphic does not show in the information
display.
The system resumes operation when you
release the accelerator pedal. The vehicle
speed decreases to the set speed, or a
lower speed if following a slower vehicle.
Changing the Set Speed
• Press and release SET+ or SET-. When
you select km/h as the display
measurement in the information
display the set speed changes in
approximately 1 km/h increments.
When you select mph as the display
measurement in the information
display the set speed changes in
approximately 1 mph increments.
• Press the accelerator or brake pedal
until you reach the desired speed. Press
and release SET+ or SET-.
• Press and hold
SET+ or SET-. The set
speed changes in approximately 5 mph
(10 km/h)
increments.
The system may apply the brakes to slow
the vehicle to the new set speed. The set
speed displays continuously in the
information display when the system is
active. Resuming the Set Speed
Press and release RES. Your vehicle speed
returns to the previously set speed and gap
setting.
Note:
Only use resume if you are aware of
the set speed and intend to return to it.
Automatic Cancellation
The system does not operate below
12 mph (20 km/h)
. An audible warning
sounds and the automatic braking releases
if the vehicle drops below this speed.
Automatic cancellation can also occur if:
• The tires lose traction.
• The engine speed is too low.
• You apply the parking brake.
Note: A message is shown in the display if
the engine speed drops too low.
Hilly Condition Usage
You should select a lower gear position
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 them from overheating.
Note: An audible warning sounds and the
system shuts down if it applies brakes for
an extended period of time. This allows the
brakes to cool down. The system functions
normally again when the brakes have cooled
down.
Switching Adaptive Cruise Control
Off
Press and release
OFF when the system is
in stand by mode or switch the ignition off.
Note: You erase the set speed when you
switch the system off.

A message displays if something obstructs
the radar signals from the sensor. The
sensor is located on the lower grille. The
system cannot detect a vehicle ahead and
does not function when something
obstructs the radar signals.
The following table lists possible causes and actions for this message displaying. Action
Cause
Clean the grille surface in front of the radar
or remove the object causing the obstruc-
tion.
The surface of the radar in the grille is dirty
or obstructed in some way.
Wait a short time. It may take several
minutes for the radar to detect that it is free
from obstruction.
The surface of the radar in the grille is clean
but the message remains in the display.
Do not use the system in these conditions
because it may not detect any vehicles
ahead.
Heavy rain or snow is interfering with the
radar signals.
Do not use the system in these conditions
because it may not detect any vehicles
ahead.
Swirling water, or snow or ice on the surface
of the road may interfere with the radar
signals.
Wait a short time or switch to normal cruise
control.
You are in a desert or remote area with no
other vehicles and no roadside objects.
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 environments.
A false blocked condition self clears or
clears after a key cycle.
Switching to Normal Cruise
Control WARNING
Normal cruise control will not brake
when your vehicle is approaching
slower vehicles. Always be aware of
which mode you have 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
replaces the adaptive cruise
control indicator light if you
select normal cruise control. The gap
setting does not display, the system does
not automatically respond to lead vehicles.
Automatic braking remains active to
maintain set speed.

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.
200
Flex (), enUSA, First Printing Driving Aids

WARNINGS
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 sensitivity can be
adjusted to one of three possible settings
by using the information display control.
See
General Information (page 99).
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. See
General
Information (page 99).
Blocked Sensors 201
Flex (), enUSA, First Printing Driving AidsE156130 E156131 E145632

If a message regarding a blocked sensor
appears in the information display, the
radar signals from the sensor have been
obstructed. The sensors are located behind
a fascia cover near the driver side of the
lower grille. When the sensors are
obstructed, a vehicle ahead cannot be
detected and the collision warning system
does not function. The following table lists
possible causes and actions for this
message being displayed. Action
Cause
Clean the grille surface in front of the radaror remove the object causing the obstruc- tion
The surface of the radar in the grille is dirty
or obstructed in some way
Wait a short time. It may take several
minutes for the radar to detect that it is no longer obstructed
The surface of the radar in the grille is clean
but the message remains in the display
The collision warning system is temporarily
disabled. Collision warning should automat-ically reactivate a short time after the weather conditions improve
Heavy rain, spray, snow, or fog is interfering
with the radar signals
The collision warning system is temporarily
disabled. Collision warning should automat-ically reactivate a short time after the weather conditions improve
Swirling water, or snow or ice on the surface
of the road may interfere with the radar signals
System Limitations 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. Due to the nature of radar technology,
there may be certain instances where
vehicles do not provide a collision warning.
These include:
•
Stationary vehicles or vehicles moving
below 6 mph (10 km/h).
• Pedestrians or objects in the roadway.
• Oncoming vehicles in the same lane. •
Severe weather conditions (see
blocked sensor section).
• Debris build-up on the grille near the
headlamps (see blocked sensor
section).
• Small distance to vehicle ahead.
• Steering wheel and pedal movements
are large (very active driving style).
If the front 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.

Safety Compliance Certification Label
Example:
WARNING
Exceeding the Safety
Compliance Certification
label vehicle weight limits can
adversely affect the performance
and handling of your vehicle,
cause vehicle damage and can
result in the loss of control of your
vehicle, serious personal injury or
death. Maximum Loaded Trailer
Weight
Maximum loaded trailer weight is
the highest possible weight of a
fully loaded trailer the vehicle can
tow. Consult an authorized dealer
(or the RV and Trailer Towing
Guide available at an authorized
dealer) for more detailed
information.
GCWR (Gross Combined
Weight Rating)
GCWR is the maximum allowable
weight of the vehicle and the
loaded trailer, including all cargo
and passengers, that the vehicle
can handle without risking
damage. (Important: The towing vehicle
’s braking system is rated
for operation at Gross Vehicle
Weight Rating, not at Gross
Combined Weight Rating.)
Separate functional brakes should
be used for safe control of towed
vehicles and for trailers where the
Gross Combined Weight of the
towing vehicle plus the trailer
exceed the Gross Vehicle Weight
Rating of the towing vehicle.
The gross combined weight must
never exceed the Gross Combined
Weight Rating.
Note: For trailer towing
information refer to the RV and
Trailer Towing Guide available at
an authorized dealer. WARNINGS
Do not exceed the GVWR or
the GAWR specified on the
certification label. Do not use replacement tires
with lower load carrying
capacities than the original tires
because they may lower your
vehicle's GVWR and GAWR
limitations. Replacement tires
with a higher limit than the original
tires do not increase the GVWR
and GAWR limitations. 206

TOWING A TRAILER
WARNINGS
Do not exceed the GVWR or
the GAWR specified on the
certification label. Towing trailers beyond the
maximum recommended
gross trailer weight exceeds the
limit of your vehicle and could
result in engine damage,
transmission damage, structural
damage, loss of vehicle control,
vehicle rollover and personal
injury. Note:
Your vehicle may have
electrical items, such as fuses or
relays, related to towing. See
Fuses (page 233).
Your vehicle's load capacity
designation is by weight, not by
volume, so you cannot necessarily
use all available space when
loading a vehicle or trailer.
Towing a trailer places an extra
load on your vehicle's engine,
transmission, axle, brakes, tires
and suspension. Inspect these
components periodically during,
and after, any towing operation. Load Placement
To help minimize how trailer
movement affects your vehicle
when driving:
•
Load the heaviest items closest
to the trailer floor.
• Load the heaviest items
centered between the left and
right side trailer tires.
• Load the heaviest items above
the trailer axles or just slightly
forward toward the trailer
tongue. Do not allow the final
trailer tongue weight to go
above or below 10-15% of the
loaded trailer weight.
• Select a ball mount with the
correct rise or drop. When both
the loaded vehicle and trailer
are connected, the trailer frame
should be level, or slightly
angled down toward your
vehicle, when viewed from the
side.
When driving with a trailer or
payload, a slight takeoff vibration
or shudder may be present due to
the increased payload weight.
Additional information regarding
proper trailer loading and setting
your vehicle up for towing is
located in the Load Carrying
chapter. See
Load Limit (page
203).
You can also find information in
the
RV & Trailer Towing Guide
available at your authorized
dealer, or online.

TRAILER SWAY CONTROL 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 107). Slow
your vehicle down, pull safely to the side
of the road and check for correct load
distribution. See Load Carrying (page
203).
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 feet² (1.86
meters²) if your vehicle can tow a
class I trailer or 40 feet² (3.72
meters²) if your vehicle can tow a
class III trailer.
Note: For high altitude operation,
reduce the gross combined weight
by 2% per 1000 feet (300 meters)
starting at the 1000 foot (300
meter) 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
vehicle ’s electrical system may not
include the wiring connector
needed to use electric trailer
brakes.
