Hill Descent Control (HDC)

The HDC warning lamp is controlled by the ABS ECU and the instrument pack software. The lamp illuminates briefly in a green color when the ignition is moved to position II. The lamp is also illuminated when HDC is selected on and the vehicle speed is less than 20 mph (35 km/h).

If HDC is selected on and the vehicle speed is faster than the operating speed, the lamp will flash and a message 'NO HDC, SLOW DOWN' will be displayed in the message center.

If the use of HDC causes the brake discs to exceed their pre-determined temperature, the HDC initiates 'fade out'. The lamp flashes during 'fade out' and a message 'HDC TEMP.NOT AVAIL' will be displayed in the message center. When the brake discs have cooled, HDC is reactivated, the lamp illuminates and the message is removed from the message center.
