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

PRINCIPLE OF OPERATION

HDC operates in conjunction with stability
control (ESP) 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 and Hill Descent
Control (HDC).

Hill descent control (HDC)

Note: Once HDC is selected, it will be
activated at speeds below 35 km/h (22
mph) and deactivated above 40 km/h (25
mph) but will not turn off until vehicle speed
exceeds 60 km/h (37 mph).
Note: HDC will be turned off when the
ignition is off.
The HDC switch will illuminate
continuously to indicate that
HDC is fully active.
HDC will temporarily deactivate during the
following conditions:
• High brake temperature. Operation
resumes once the brakes cool down.
• ESP on warning lamp is illuminated
and operating.
• Electronic locking differential is
operating.

HDC operation

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.
