Terrain Response; Principle Of Operation; Using Hill Descent Control - Ford 2015 F-150 Owner's Manual

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
E163957
cluster will illuminate and a chime will
sound when this feature is activated.
To increase descent speed, press the
accelerator pedal until you reach the
desired speed. To decrease descent
speed, press the brake pedal until you
reach the desired speed.
When accelerating or decelerating, once
you reach the desired descent speed,
remove your feet from the pedals and hill
descent control maintains the chosen
vehicle speed.
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 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 indicator light 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 indicator light
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.
