Action
Message
The four wheel drive system has automatically disabled itself due to the system overheating.
4WD Temporarily
Disabled
The four wheel drive system is locking up the torque transfer clutch to help reduce clutch temperature.
4WD Temporarily
Locked
Displays when the system automatically disables to protect itself.
This may be caused by operating the vehicle with a mini spare tire installed, if the system detects dissimilar size tires, or if there is an
issue with another vehicle system preventing 4WD operation. The system resumes normal operation and clears this message after
you cycle the ignition on and off and drive a short distance with the road tire re-installed or after the other vehicle system issues are resolved.
4WD Off
Displays after the system cools and the four wheel drive system resumes normal function.
4WD Restored
The four wheel drive system is not operating properly and the
powertrain fault indicator illuminates. If the warning stays illumin- ated or continues to illuminate, contact an authorized dealer as soon as possible.

PRINCIPLE OF OPERATION
This system is a proactive system. It has
the ability to anticipate wheel slip and
transfer torque to the front wheels before
slip occurs. Even when wheel slip is not
present, the system is continuously
adjusting to the torque distribution, in an
attempt to improve straight line and
cornering behavior, both on and off road.
The system automatically turns on every
time you switch the ignition on.
If any component requires maintenance,
a message appears in the information
display.
USING FOUR-WHEEL DRIVE
WARNING: Vehicles with a higher
center of gravity (utility and four-wheel
drive vehicles) handle differently than
vehicles with a lower center of gravity
(passenger cars). Avoid sharp turns,
excessive speed and abrupt steering in
these vehicles. Failure to drive cautiously
increases the risk of losing control of your
vehicle, vehicle rollover, personal injury
and death.
The intelligent 4WD system continuously
monitors vehicle conditions and adjusts
the power distribution between the front
and rear wheels. It combines transparent
all-surface operation with highly capable
four-wheel drive.
The 4WD system is always active and
requires no driver input. It is capable of
handling all road conditions including
street and highway driving as well as
off-road and winter driving. You can
optimize more 4WD control by selecting
different drive modes. See
Selecting a
Drive Mode (page 278). Note:
A warning message displays in the
information display when a 4WD system
fault is present. See
Information
Messages (page 121). A 4WD system fault
causes the 4WD system to default to
rear-wheel drive only mode. When this
warning message is displayed, have your
vehicle serviced at an authorized dealer.
Note: A warning message displays in the
information display if the 4WD system
overheats. See
Information Messages
(page 121). This condition could occur if the
vehicle is operated in extreme conditions
with excessive wheel slip, such as deep
sand. To resume normal 4WD function as
soon as possible, stop the vehicle in a safe
location and stop the engine for at least 10
minutes. After the engine is restarted and
the 4WD system is adequately cooled, the
warning message turns off and normal 4WD
function returns.
Operating Four-Wheel Drive (4WD)
Vehicles With Spare Tires
Do not use a different size spare tire other
than the tire provided. If the mini-spare tire
is installed, the 4WD system will disable
and enter rear-wheel drive only mode to
protect driveline components. Some
limited 4WD traction could be provided if
the mini-spare is installed on one of the
front wheels. If you are in driving conditions
where limited 4WD traction is needed
while the mini-spare is installed, it is
recommended the mini-spare be installed
on the front axle.
See Information
Messages (page 121).
If the mini-spare is installed, this condition
is indicated by a warning in the information
display. If there is a warning message in
the information display from using the
spare tire, this indicator should turn off
after reinstalling or replacing the normal
road tire and cycling the ignition off and
on. We recommended reinstalling or

HOW DOES ADAPTIVE CRUISE
CONTROL WITH STOP AND GO
WORK
Adaptive cruise control with stop and go
uses radar and camera sensors to adjust
the speed of your vehicle to maintain a set
gap from the vehicle in front of you in the
same lane while following it to a complete
stop. You can also engage the system to
follow a vehicle in front of you and adjust
set speed while stopped.
WHAT IS ADAPTIVE CRUISE
CONTROL WITH LANE
CENTERING
Adaptive cruise control with lane centering
uses radar and camera sensors to help
keep your vehicle in the lane by applying
continuous assistance steering torque
input toward the lane center on highways.
Note:
The adaptive cruise control gap
setting operates normally.
WHAT IS INTELLIGENT
ADAPTIVE CRUISE CONTROL
Intelligent adaptive cruise control
combines speed sign recognition with
adaptive cruise control to adjust the cruise
set speed to the speed limit detected by
the speed sign recognition system. For
example, if the speed sign recognition
system detects a 50 mph (80 km/h)
speed limit, the cruise set speed is updated
to
50 mph (80 km/h).
Note: The adaptive cruise control gap
setting operates normally. ADAPTIVE CRUISE CONTROL

Evasive Steering Assist (If Equipped)
If your vehicle is rapidly approaching a
stationary vehicle or a vehicle traveling in
the same direction as your vehicle, the
system is designed to help you steer
around the vehicle.
The system only activates when all of the
following occur:
• The Pre-Collision Assist system detects
a vehicle ahead and starts to apply
Active Braking.
• You turn the steering wheel in an
attempt to steer around the vehicle.
After you turn the steering wheel, the
system applies additional steering torque
to help you steer around the vehicle. After
you pass the vehicle, the system applies
steering torque in the opposite direction to
encourage you to steer back into the lane.
The system deactivates after you fully pass
the vehicle.
Note: The system does not automatically
steer around a vehicle. If you do not turn the
steering wheel, the system does not
activate.
Note: The system does not activate if the
distance to the vehicle ahead is too small
and the system cannot avoid a crash.
Adjusting the Pre-Collision Assist
Settings
You can adjust the following settings by
using the touchscreen. See Settings (page
464
).
• You can change Alert and Distance
Alert sensitivity to one of three possible
settings.
• You can switch Distance Indication and
Alert on or off. •
If required, you can switch Active
Braking on or off.
• If required, you can switch Evasive
Steering Assist on or off.
Note: Active Braking and Evasive Steering
Assist automatically turn on every time you
switch the ignition on.
Note: If you switch Active Braking off,
Evasive Steering Assist turns off.

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 121). Slow
your vehicle down, pull safely to the side
of the road and check for correct load
distribution. See
Load Carrying (page
282).
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: Be 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 55 ft² (5.11 m²) if your
vehicle can tow a class III trailer
weighing more than
5,000 lb
(2,267 kg).
Note: Your vehicle could have
reduced performance when
operating at high altitudes, and
when heavily loaded or towing a
trailer. When driving at elevation,
in order to match driving
performance as perceived at sea
level, reduce gross vehicle weight
and gross combination weight by
2% per
1,000 ft (300 m) of
elevation.
