parking brake pedal down again.
If you are parking your vehicle on a grade
or with a trailer, press and hold the brake
pedal down, then set the parking brake.
There may be a little vehicle movement as
the parking brake sets to hold the vehicle's
weight. This is normal and should be no
reason for concern. If needed, press and
hold the service brake pedal down, then
try reapplying the parking brake. Chock the
wheels if required. If the parking brake
cannot hold the weight of the vehicle, the
parking brake may need to be serviced or
the vehicle may be overloaded.
ELECTRIC PARKING BRAKE (If
Equipped)
The electric parking brake replaces the
conventional foot brake. The operating
switch is located on the instrument panel
left of the steering wheel. WARNING
Always set the parking brake fully
and make sure the transmission is
locked in park (P). Failure to set the
parking brake and engage park could result
in vehicle roll-away, property damage or
bodily injury. Note:
When you apply the electric parking
brake in certain conditions, for example, on
a steep hill, the electric parking brake may
reapply the brakes within ten minutes. Note:
You may notice various noises when
you apply and release the electric parking
brake. This is normal and no cause for
concern.
Applying the Electric Parking
Brake WARNING
If the brake system warning lamp
does not illuminate or flashes, there
could be a problem with your electric
parking brake. Have the system checked
by an authorized dealer as soon as
possible. Pull the switch up to apply the electric
parking brake.
The brake system warning lamp will
illuminate to confirm that the electric
parking brake has been applied. See
Information Displays
(page 105).
Note: The brake system warning lamp will
remain illuminated for about ten seconds if
you switch the ignition off with the parking
brake applied, or apply the parking brake
while the ignition is off.
Note: The electric parking brake will not
automatically apply. You must apply the
electric parking brake using the electric
parking brake switch.

Applying the Electric Parking
Brake When the Vehicle is Moving
WARNINGS
Applying the electric parking brake
while moving will result in use of the
anti-lock braking system. Do not use
the electric parking brake system when the
vehicle is moving unless the normal brake
system is unable to stop the vehicle. With the exception of emergency
conditions (for example, the brake
pedal does not work or is blocked),
do not apply the electric parking brake
while the vehicle is moving. On bends, or
poor road surfaces or weather conditions,
emergency braking can cause the vehicle
to skid out of control or off the road. If you apply the electric parking brake when
your vehicle is moving, the brake system
warning lamp will illuminate and a warning
tone will sound. See Information
Displays (page 105).
If your vehicle speed is above
4 mph
(6 km/h), the braking force is applied as
long as the switch is pulled. Release or
press the switch or press the accelerator
pedal to stop the braking force. Releasing the Electric Parking
Brake You can release the electric parking brake
either manually by pressing the switch or
automatically.
Manual Release
WARNING
If the brake system warning light
remains illuminated or flashes after
you have released the parking brake,
there could be a problem with your braking
system. Have the system checked by an
authorized dealer as soon as possible. You can manually release the electric
parking brake by:
1. Switching the ignition on.
2. Pressing the brake pedal.
3. Pressing the electric parking brake
switch.
When the electric parking brake is released,
the brake system warning lamp will turn
off.
Driving With a Trailer
Depending on the grade and the weight of
the trailer, your vehicle and trailer may roll
backwards slightly when you start on a
slope.

the slope without rolling away for
about two to three seconds. This hold
time automatically extends if you are
in the process of driving off.
4. Drive off in the normal manner. The system releases the brakes
automatically.
Note: When you remove your foot from the
brake pedal and press the pedal again when
the system is active, you will experience
significantly reduced brake pedal travel. This
is normal.
Switching the System On and Off
When you switch the ignition on, the
system automatically turns on. You can
switch the system on or off in the
information display. See General
Information (page 105). The system

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.
