Hill Descent Control
HILL DESCENT CONTROL
If the vehicle speed is too high when an attempt
to select HDC is made, ‘NO HDC - SLOWDOWN’
appears in the message center and the HDC
warning light will extinguish when the switch is
released.
Hill Descent Control
To deselect HDC, move the switch rearwards
(the warning light will extinguish). If HDC is
deselected when HDC is operating, the warning
light will flash as the system ‘fades out’ -
allowing the vehicle to gradually increase in
speed.
When used in LOW range, HDC controls the
vehicle speed more aggressively. Use LOW
range gears when steep descents are to be
attempted.
NOTE: If the vehicle speed exceeds 35 mph
(60
km/h) when in HIGH range, HDC will be
automatically deselected (warning light
extinguishes). HDC is also automatically
deselected if the vehicle ignition is switched off
for more than 6 hours.
Hill Descent Control in action
HDC can be used with the transmission in
CommandShift mode, in ‘R’ (reverse) and ‘D’
(drive). When in ‘D’, the vehicle will

Hill Descent Control (HDC) operates in
conjunction with the anti-lock braking system
to provide greater control in off-road situations
particularly when descending severe gradients.
automatically select the most appropriate gear.
During a descent, if engine braking is
insufficient to control the vehicle speed, HDC (if
selected) automatically operates the brakes to
slow the vehicle and maintain a speed relative
to the selected gear range and the accelerator
pedal position.
To select HDC
HDC can be selected at any speed if LOW range
is selected in the transfer gearbox, and can be
selected at up to 20 mph (35 km/h) if the
vehicle is in HIGH range. The HDC ‘Information’
warning light in the instrument pack will
illuminate when HDC has been successfully
selected.
When driving off-road, HDC can be
permanently selected, to ensure that control is
maintained. ABS and traction control are still
fully operational and will assist if the need
arises.
Move the switch (arrowed) fully rearwards to
select HDC.
NOTE: With HDC selected, gear changes can be
carried out in the normal way.
