Hill Descent Control
HILL DESCENT CONTROL
Hill descent control in action
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 and the accelerator pedal
position.
Hill Descent Control
When driving off-road, HDC can be
permanently selected, to ensure that control is
maintained whenever low range gears are
engaged. ABS and traction control are still fully
operational and will assist if the need arises.
NOTE: With HDC selected, gear changes can be
carried out in the normal way.
If the brake pedal is depressed when HDC is
active, HDC is overridden and the brakes will
perform as normal (a pulsation might be felt
through the brake pedal). If the brake pedal is
then released, HDC will recommence operating
if necessary.
H2617
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.
If the clutch is depressed for longer than 3
seconds while HDC is operating, the HDC
information light will flash. If, after 60 seconds
the clutch is still depressed, the information
light extinguishes and the HDC ‘failure’ warning
light flashes as the system gradually fades out
(see ‘HDC fade-out’, page 113).
To select HDC
HDC can be selected with the vehicle in any
gear, but will only operate when low range
gears are engaged with the vehicle travelling at
less than 50 km/h, and the clutch is engaged
(manual gearbox vehicles).
In extreme circumstances, the HDC system
may cause brake temperatures to exceed their
pre-set limits. If this occurs, the HDC ‘failure’
warning light (AMBER) will start to flash and
the warning chime will sound continuously.
During this time HDC will function as normal.
Press the switch (illustrated above) to select
HDC.
If low range gears are engaged, the HDC
information light (GREEN) on the instrument
panel will illuminate (if low range gears have
NOT been selected, the light will flash).
To avoid further cause for brake temperatures
to rise, engage an appropriate low gear for
steep descents and avoid descending hills at
higher than the minimum descent speed. If the
To deselect HDC, press the switch a second
time (the information light will extinguish and a
single warning sound will chime).
‘failure’ warning light continues to flash, the
HDC system will gradually fade out (see ‘HDC
fade-out’, page 113).
