HILL DESCENT CONTROL (HDC) OVERVIEW

WARNING

Do not attempt a steep descent if the Hill Descent Control (HDC) system is inoperative or warning messages are displayed. Doing so may potentially result in damage to the vehicle or personal injury.

The HDC system restricts the vehicle's speed to a set limit when traveling downhill.

The HDC button is located on the center console. The speed limits for the HDC system are adjusted via the control buttons mounted on the right side of the steering wheel.

Dependent on the vehicle's specification, the HDC button also operates the All Terrain Progress Control (ATPC) system. See USING THE PROGRESS CONTROL SYSTEM.

Operate the HDC system as follows:

  1. HDC button: Press and release to enable the HDC system. The instrument panel displays a confirmation message and illuminates the HDC warning lamp to confirm selection. Press and release the button again to disable the HDC system. The instrument panel displays a confirmation message and extinguishes the HDC warning lamp to confirm deselection. See HILL DESCENT CONTROL (HDC) (GREEN).

    NOTES

    The HDC system is automatically selected by some of the terrain response driving programs.

    NOTES

    The HDC system is automatically deselected if the ignition is switched off for more than 6 hours.

  2. SET + button: Press and release to increase the descent set speed in increments of 0.6 mph (1 km/h). Alternatively, press and hold the button for larger incremental increases, up to the maximum permissible set speed.

    NOTES

    Each gear has a predetermined maximum speed.

    NOTES

    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.

  3. - button: Press and release to decrease the descent set speed in increments of 0.6 mph (1 km/h). Alternatively, touch and hold for larger incremental decreases, down to the minimum permissible set speed.

    NOTES

    Each gear has a predetermined minimum speed.

When the HDC system is enabled, the instrument panel displays a graphic showing the current set speed. The graphic also indicates the range of set speeds available for the current gear selection.

If the HDC system is deselected while operating, the warning lamp extinguishes. HDC operation fades out, allowing the vehicle's speed to gradually increase.

The HDC system can be selected at any speed, but only operates at vehicle speeds of less than 31 mph (50 km/h).

If the HDC system is enabled and the vehicle's speed exceeds 31 mph (50 km/h), HDC operation is suspended. The instrument panel displays a suspended message and the graphic illuminates grey. The HDC warning lamp also flashes.

NOTES

If the vehicle's speed exceeds 50 mph (80 km/h), the HDC system disables. The instrument panel displays a disabled message and extinguishes the HDC warning lamp.

If the brake pedal is pressed when the HDC system is active, a pulsation may be felt through the brake pedal. When the brake pedal is released, HDC operation resumes.

If an HDC system fault is detected, the instrument panel displays a message indicating that HDC is not available. In this event, contact a retailer/authorized repairer as soon as possible.

If a fault is detected during operation of the HDC system, HDC operation fades out.
