Hill Descent Control (HDC) is automatically engaged for some Terrain Response programs. If required, HDC can be deselected or engaged independently of Terrain Response. See HILL DESCENT CONTROL (HDC) OVERVIEW.
The HDC status will be displayed in the Message centre whether it is engaged, or disengaged, by the system or by the driver.
Although Dynamic Stability Control (DSC) is automatically engaged when a special program is selected, it can be turned off if required. See SWITCHING DSC OFF.
