HILL DESCENT CONTROL (HDC) [G2769091]

Hill Descent Control (HDC) restricts the vehicle’s speed to a set limit when travelling downhill.

WARNING:

Do not attempt a steep descent if HDC is inoperative or warning messages are displayed. Doing so could lead to loss of vehicle control, resulting in vehicle damage, personal injury, or death.

The HDC button is located on the centre console. The HDC button also controls operation of the All Terrain Progress Control (ATPC) system. See ALL TERRAIN PROGRESS CONTROL (ATPC) OVERVIEW.

The button operates as follows:

  1. A first press of the button enables the HDC system.
  2. A second press of the button disables the HDC system, and enables ATPC.
  3. A third press of the button disables ATPC.

The instrument panel displays a confirmation message and illuminates the HDC information lamp to confirm HDC has been selected. See HILL DESCENT CONTROL (HDC) (GREEN).

NOTE:

HDC is automatically selected by some terrain response driving programs.

HDC remains selected for up to 6 hours after the vehicle’s ignition is switched off.

Press the HDC button a second time to deselect HDC. The instrument panel displays a confirmation message and extinguishes the HDC information lamp. If HDC is deselected while it is active, operation fades out, allowing the vehicle's speed to increase.

To adjust the vehicle’s rate of descent:

  1. Move the SET button upward, and release, to increase the vehicle’s speed in increments of 1 km/h (0.6 mph). Move and hold the SET button for larger increases, up to the maximum permissible speed.
  2. Move the SET button downward, and release, to decrease the vehicle’s speed in increments of 1 km/h (0.6 mph). Move and hold the SET button for larger decreases, down to the minimum permissible speed.

The instrument panel displays the current set speed and the range of set speeds available.

NOTE:

The maximum and minimum permissible speeds are dependent on the gear selection.

NOTE:

The vehicle’s speed only increases on a slope steep enough to increase momentum. Using the SET button may not increase the vehicle’s speed on a gentle slope.

NOTE:

A pulsation may be felt through the brake pedal if the brakes are used when HDC is active. HDC operation resumes when the brake pedal is released.
