Ford Super Duty (2018 year). Manual — part 58

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

E163957

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 below 20 mph (32 km/h):
When the Hill Descent Control switch
is pressed and Hill Descent Control is
active, the Hill Descent Control telltale
will flash.

•

At speeds below 20 mph (32 km/h):
When the Hill Descent Control switch
is pressed and conditions are not
correct for hill descent activation, the
Hill Descent Control system will be
enabled, the Hill Descent Control
telltale will be solid and a message will
display in the information display.

•

At speeds above 20 mph (32 km/h):
When the Hill Descent Control switch
is pressed, the Hill Descent Control
system will be enabled, the telltale in
the cluster will not be illuminated and
a message will be displayed in the
information display.

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: Certain add-on devices installed
around the bumper or fascia may create
false beeps. 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.

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. See your
authorized technician.

Note: When a trailer is connected to your
vehicle, the rear parking aid may detect the
trailer and therefore provide warnings.
Disable the rear parking aid when a trailer
is connected to prevent these warnings.

Note: The sensing system cannot be turned
off when a MyKey is present. See Principle
of Operation (page 63).

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.

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.

The sensing 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 114).

If a fault is present in the system, a warning
message appears in the information
display and you cannot switch the system
on through the pop-up message. See
Information Messages (page 131).

REAR PARKING AID

(If Equipped)

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.

E231381

Coverage area of up to 6 ft (1.8 m) from
the rear bumper. There may be decreased
coverage area at the outer corners of the
bumper.

The system detects certain objects while
the transmission is in reverse (R) :
•

Your vehicle is moving toward a
stationary object at a speed of 3 mph
(5 km/h) or less.

•

Your vehicle is not moving, but a
moving object is approaching the rear
of your vehicle at a speed of 3 mph
(5 km/h) or less.

•

Your vehicle is 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 less than 12 in (30 cm) away
from the bumper.

Obstacle Distance Indicator

(If

Equipped)

The system provides obstacle distance
indication through the display screen. See
Rear View Camera (page 238).

REAR VIEW CAMERA

(If Equipped)

WARNINGS

The rear view camera system is a
reverse aid supplement device that
still requires the driver to use it in

conjunction with the interior and exterior
mirrors for maximum coverage.

Objects that are close to either
corner of the bumper or under the
bumper, might not be seen on the

screen due to the limited coverage of the
camera system.

Reverse your vehicle as slow as
possible, higher speeds may limit
your reaction time to stop your

vehicle.

Use caution when the tailgate is ajar.
If the tailgate is ajar, the camera will
be out of position and the video

image may be incorrect. All guidelines
disappear when the tailgate is ajar. Some
vehicles may not come equipped with
guidelines.

Use caution when turning camera
features on or off when the
transmission is not in park (P). Make

sure your vehicle is not moving.

The rear view camera system displays
what is behind your vehicle when you shift
the transmission into reverse (R).

During operation, lines appear in the
display that represents the path of your
vehicle and proximity to objects behind it.
