Hill Descent Control (Hdc); Principle Of Operation; Using Hill Descent Control - Ford Ranger Owner's Manual

PRINCIPLE OF OPERATION

HDC operates in conjunction with ABS to
provide greater control when off-road,
particularly when descending steep slopes.
HDC operation is fully automatic when
engaged.
During a hill descent when driving off-road,
engine braking is used to control the speed
of descent. If engine braking alone is
insufficient to control the vehicle's speed,
HDC will slow the vehicle using the braking
system.
If the vehicle is fitted with a manual
transmission, HDC should only be used in
first, or reverse gears. If the vehicle is fitted
with an automatic transmission, HDC
should only be used in D, R, or Sport mode
1. When in D the vehicle will select the
most appropriate gear.
Before driving off-road
WARNING
Before driving off-road it is
absolutely essential that
in-experienced drivers become fully
familiar with the vehicle's controls. In
particular, Sport mode, Hill Descent
Control (HDC).
USING HILL DESCENT
CONTROL
Note: When the rear differential lock is
engaged, the HDC will not be available.
Selecting HDC
HDC can be selected at speeds below 60
km/h (35 mph). To select HDC, press and
release the HDC on/off switch. For item
location: See At a Glance (page 9).

Hill descent control (HDC)

The HDC switch will illuminate
continuously at speeds below
40 km/h (25 mph) to indicate
that HDC is fully active.
If the vehicle speed exceeds 60 km/h (35
mph) HDC will disengage, and the HDC
switch illumination will go off.
HDC operation
E102680
With HDC engaged, the speed of descent
can be altered using the cruise control
steering wheel switches. SET + increases
the speed, and SET - decreases the speed.
To increase speed press, and hold, the SET
+ switch until the desired speed is
achieved. When the switch is released, the
speed will be maintained.
To decrease speed press, and hold, the
SET - switch until the desired speed is
achieved. When the switch is released, the
speed will be maintained.
To increase or decrease speed gradually,
tap the SET + or SET - switch as required.
Each tap of the switch will increase, or
decrease the speed in increments of 0.5
km/h (0.3 mph). The speed can also be
increased or decreased by pressing the
accelerator pedal or brake pedal
respectively.
Note: Each gear has a pre-determined
minimum speed.
