A green graphic will also be displayed in the

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.
HILL DESCENT CONTROL (HDC)
CONTROLS
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.
HDC OPERATION
With HDC engaged, standard descent speed
will not exceed 20km/h (12.4mph).
While the green warning lamp is continuously
illuminated, HDC target speed can be modified
using the cruise control steering wheel
switches, as follows:
ꢀ
To increase speed, press and hold switch
(2) until the green pointer in the target
speed display is at the desired speed.
1. Press to switch HDC on and off.
2. Press to increase the set speed.
3. Press to decrease the set speed.
ꢀ
To decrease speed, press and hold switch
(3) until the green pointer in the target
speed display is at the desired 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.
Release the switch to set the target speed.
Note: The white needle indicates the current
vehicle speed.
Note: HDC is automatically selected by some
of the Terrain response special programs.
To increase or decrease speed gradually, tap
switches (2) and (3) as required. Each tap of
the switch will increase/decrease the speed in
increments/decrements of 1km/h (0.6mph).
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).
Note: If a new target speed is set and then
reverse gear is selected, the target speed will
change to the default reverse speed. When a
forward gear is next selected, the new target
speed is reinstated.
The green warning lamp in the message centre
will illuminate while HDC is active.
