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 AdvanceTrac
system. In addition, installing any stereo
loudspeakers may interfere with and
adversely affect the AdvanceTrac 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 AdvanceTrac sensors. Reducing the
effectiveness of the AdvanceTrac 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
AdvanceTrac 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 AdvanceTrac
system activates, SLOW DOWN. The AdvanceTrac with Roll Stability
Control system helps you keep control of
your vehicle when on a slippery surface.
The electronic stability control portion of
the system helps avoid skids and lateral
slides and roll stability control helps avoid
a vehicle rollover. The traction control
system helps avoid drive wheel spin and
loss of traction. See Using Traction
Control (page 197). Vehicle without AdvanceTrac

PRINCIPLE OF OPERATION
WARNINGS
Hill descent control cannot control
descent in all surface conditions and
circumstances, such as ice or
extremely steep grades. Hill descent
control is a driver assist system and cannot
substitute for good judgment by the driver.
Failure to do so may result in loss of vehicle
control, crash or serious injury. Hill descent control does not provide
hill hold at zero miles per hour (0
kilometers per hour). When stopped,
the parking brake must be applied or the
vehicle must be placed in P (Park) or it
may roll away. Hill descent control allows the driver to set
and maintain vehicle speed while
descending steep grades in various surface
conditions.
Hill descent control can maintain vehicle
speeds on downhill grades between 2 mph
(3 km/h) and 12 mph (20 km/h). Above 20
mph (32 km/h), the system remains
armed, but descent speed cannot be set
or maintained.
Hill descent control requires a cooling
down interval after a period of sustained
use. The amount of time that the feature
can remain active before cooling varies
with conditions. The system will provide a
warning in the message center and a chime
will sound when the system is about to
disengage for cooling. At this time,
manually apply the brakes as needed to
maintain descent speed. USING HILL DESCENT
CONTROL Press and release the hill
descent button located on the
instrument panel. A light in the
cluster will illuminate and a
chime will sound when this feature is
activated.
To increase descent speed, press the
accelerator pedal until the desired speed
is reached. To decrease descent speed,
press the brake pedal until the desired
speed is reached.
Whether accelerating or decelerating, once
the desired descent speed is reached,
remove your feet from the pedals and the
chosen vehicle speed will be maintained.
Note: Noise from the ABS pump motor may
be observed during hill descent control
operation. This is a normal characteristic of
the ABS and should be no reason for
concern.
Hill descent modes
• At speeds between
2 mph (3.2 km/h)
and 20 mph (32 km/h): When the Hill
Descent Control switch is pressed and
Hill Descent Control is active, the Hill
Descent Control telltale flashes. Your
vehicle maintains your desired speed.
• At speeds between
20 mph (32 km/h)
and 40 mph (64 km/h): When the Hill
Descent Control switch is pressed, the
Hill Descent Control system is enabled,
the Hill Descent Control telltale is solid
and a message displays in the
information display. Your vehicle does
not maintain your desired speed and
you cannot set your descent speed.

PARKING AID (If Equipped)
WARNINGS
To help avoid personal injury, please
read and understand the limitations
of the system as contained in this
section. Sensing is only an aid for some
(generally large and fixed) objects when
moving in reverse on a flat surface at
parking speeds. Certain objects with
surfaces that absorb ultrasonic waves,
traffic control systems, fluorescent lamps,
inclement weather, air brakes, and external
motors and fans may also affect the
function of the sensing system; this may
include reduced performance or a false
activation. To help avoid personal injury, always
use caution when in reverse (R) and
when using the sensing system.
This system is not designed to
prevent contact with small or moving
objects. The system is designed to
provide a warning to assist the driver in
detecting large stationary objects to avoid
damaging your vehicle. The system may
not detect smaller objects, particularly
those close to the ground. Certain add-on devices such as large
trailer hitches, bike or surfboard racks
and any device that may block the
normal detection zone of the system, may
create false beeps. 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 alarms. Note:
If your vehicle is equipped with
MyKey ™, it is possible to prevent turning
the sensing system off. See MyKey ™
(page
61).
Note: If your vehicle is equipped with a
trailer tow package and a trailer is
connected to your vehicle, the rear sensing
system will be disabled and will not allow
you to switch the system on through the
information display. When you shift your
vehicle into reverse (R), a message appears
in the information display stating that a
trailer is connected and the rear sensing
system is disabled. If equipped, the center
stack rear sensing system display will not
be present.
The sensing system warns the driver of
obstacles within a certain range of the
bumper area. The system turns on
automatically when you switch on the
ignition.
When receiving a detection warning, the
radio volume reduces to a predetermined
level. After the warning goes away, the
radio volume returns to the previous level.
You can switch the system off through the
information display menu or from the
pop-up message that appears once the
transmission is shifted into reverse (R).
If a fault is present in the system, a warning
message appears in the information
display and will not allow you to switch the
faulted system on.
Rear Sensing System
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
202
F-150 (), enUSA, First Printing Parking Aids

continuously. If a stationary or receding
object is detected farther than 12 in
(30 cm) from the side your vehicle, the
tone sounds for only three seconds. Once
the system detects an object approaching,
the warning sounds again. The coverage area is up to 6 feet
(1.8 meters) from the rear
bumper. There is decreased
coverage area at the outer
corners of the bumper.
A
The system detects certain objects while
the transmission is in reverse (R):
• and moving toward a stationary object
at a speed of
3 mph (5 km/h) or less.
• but not moving, and a moving object is
approaching the rear of your vehicle at
a speed of
3 mph (5 km/h) or less.
• and moving at a speed of less than
3 mph (5 km/h)
and a moving object
is approaching the rear of your vehicle
at a speed of less than 3 mph (5 km/h).
The system provides audio warnings only
when your vehicle is moving or when your
vehicle is stationary and the detected
obstacle is fewer than
12 in (30 cm) away
from the bumper. The system provides obstacle distance
indication through the center stack display
(if equipped). The distance indication will
be present when the transmission is in
reverse (R).
•
As the distance to the obstacle
decreases (obstacle becomes closer),
the indicator blocks will illuminate and
move towards the vehicle icon.
• If there is no obstacle detected, the
distance indicator blocks will be grayed
out.
ACTIVE PARK ASSIST (If Equipped) WARNING
Designed to be a supplementary park
aid, this system may not work in all
conditions. This system cannot
replace the driver ’s attention and
judgment. The driver is responsible for
avoiding hazards and maintaining a safe
distance and speed, even when the system
is in use. Note:
The driver is always responsible for
controlling the vehicle, supervising the
system and intervening if required.
The system detects an available parallel
parking space and automatically steers
your vehicle into the space (hands-free)
while you control the accelerator, gearshift
and brakes. The system visually and
audibly instructs you to park your vehicle.
The system may not function correctly if
something passes between the front
bumper and the parking space (a
pedestrian or cyclist) or if the edge of the
neighboring parked vehicle is high off the
ground (for example, a bus, tow truck or
flatbed truck).
Note: The sensors may not detect objects
in heavy rain, snow or other conditions that
cause disruptive reflections.
203
F-150 (), enUSA, First Printing Parking AidsE130178

Note:
Keep the sensors, located on the
bumper or fascia, free from snow, ice and
large accumulations of dirt. Covered sensors
can affect the system's accuracy. Do not
clean the sensors with sharp objects.
Note: The sensors may not detect objects
with surfaces that absorb ultrasonic waves.
Do not use the system if:
• You have attached a foreign object
(bike rack or trailer) to the front or rear
of your vehicle or close to the sensors.
• You have attached an overhanging
object (surfboard) to the roof.
• A foreign object damages or obstructs
the rear bumper side sensors.
• A mini-spare tire is in use. Using Active Park Assist Press the button located on the
center console near the gearshift
lever.
The touchscreen displays a message and
a corresponding graphic to indicate it is
searching for a parking space. Use the
direction indicator to indicate which side
of your vehicle you want the system to
search.
Note: The system automatically searches
on the passenger side. You can use the
direction indicator to toggle between the
driver and passenger side. When the system finds a suitable space,
the touchscreen displays a message and
a tone sounds. Stop your vehicle and
follow the instructions on the touchscreen.
If your vehicle is moving very slowly, you
may need to pull forward a short distance
before the system is ready to park.
Note:
You must observe that the selected
space remains clear of obstructions at all
times in the maneuver.
Note: Active park assist may not detect
vehicles with overhanging loads (a bus or a
truck), street furniture and other items. You
must make sure the selected space is
suitable for parking. Note:
You should drive your vehicle as
parallel to the other vehicles as possible
while passing a parking space.
Note: The system always offers the last
detected parking space (for example, if the
vehicle detects multiple spaces while you
are driving, it offers the last one).
Note: If driven above approximately 22 mph
(35 km/h), the touchscreen shows a
message to alert you to reduce your vehicle
speed.

Automatic Steering into Parking
Space
Note:
If your vehicle speed exceeds 6 mph
(9 km/h), the system turns off and you need
to take full control of your vehicle.
Note: If an object interrupts a maneuver
before completion, the system turns off. The
steering wheel position does not indicate
the actual position of the steering and you
have to take full control of your vehicle. When you shift the transmission into
reverse (R), with your hands off the wheel
(and nothing obstructing its movement),
your vehicle steers itself into the space.
Indicated by tones, instructions to move
your vehicle back and forth in the space
display on the touchscreen.When you think your vehicle has enough
space in front and behind it, or you hear a
solid tone from the parking aid
(accompanied by a touchscreen display
message and a chime), bring your vehicle
to a complete stop.
When automatic steering is finished, the
touch screen displays a message and a
tone sounds, indicating that the active park
assist process is done. The driver is
responsible for checking the parking job
and making any necessary corrections
before putting the transmission in park (P).
Deactivating the Park Assist
Feature
Manually deactivate the system by:
•
Pressing the active park assist button.
• Grabbing the steering wheel. •
Driving above approximately
22 mph
(35 km/h) for 30 seconds during an
active park search.
• Driving above
6 mph (9 km/h) during
automatic steering.
• Turning off the traction control system.
Certain vehicle conditions can also
deactivate the system, such as:
• Traction control has activated on a
slippery or loose surface.
• There is an anti-lock brake system
activation or failure.
• Something touches the steering wheel.
If a problem occurs with the system, a
warning message displays, followed by a
tone. Occasional system messages may
occur in normal operation. For recurring or
frequent system faults, contact an
authorized dealer to have your vehicle
serviced.
