Range Rover Evoque: Hill descent control (HDC) controls

Hill descent control (HDC) controls
1. Press to switch HDC on and off.
2. Press to increase the set speed.
3. Press to decrease the set speed.
Manual transmission: HDC can be used in 1st,
2nd or reverse gears.
Automatic transmission: HDC can be used in
D, R and CommandShift 1, 2 or 3.
Note: HDC is automatically selected by some
of the Terrain response special programs.
HDC can be selected at speeds above 80km/h
(50mph) but will not engage until vehicle speed
drops below 50km/h (30mph). The HDC
warning lamp will flash while vehicle speed is
above 50km/h (30mph).
The green warning lamp in the message centre
will illuminate while HDC is active.
A green graphic will also be displayed in the
message centre showing the HDC target speed.
When HDC is unable to operate, the display will
be grey. The graphic indicates the range of
target speeds available in the currently selected
gear. Target speed is adjusted via the cruise
control switches.
If HDC is deselected while operating, the green
warning lamp will flash and the system will
fade out, allowing vehicle speed to gradually
increase.
Note: HDC is automatically deselected if the
ignition is switched off for more than 6 hours.

using the cruise control steer
With HDC activated, if the vehicle is stopped on
a slope using the foot brake, GRC will become
active (except in Terrain Response Sand
program). It operates in all gears and in neutral
position.
In extreme circumstances, the HDC system
may cause brake temperatures to exceed their
pre-set limits. An HDC warning will be
displayed in the message centre. HDC will then
fade out and become temp
