6. HDC (HILL DESCENT CONTROL)
System Overview
The HDC system is an automatic descent control device that allows the vehicle to automatically decelerate to about
7 km/h by 0.1G, on steep roads (slope level exceeding 10%) through a separately installed switch operation. When
the vehicle speed reaches below 7 km/h (refer to the information below), the HDC automatically terminates the
operation.
HDC Switch
HDC Indicator (Instrument Panel) Sensor Cluster (G Sensor)
When you see a steep downhill ahead, press the HDC
switch and the green HDC indicator comes on. When
the G sensor within the sensor cluster detects a slope
level exceeding 10%, the ESP’s HDC function operates.
When this occurs, the green HDC indicator flashes
along with a loud operation sound.
When you press the HDC switch, the green
HDC indicator comes on, and when the HDC
operates, the green HDC indictor flashes at
0.5 second of interval.
The G Sensor within the sensor cluster detects the
steepness of driving roads. When the HDC switch
is in operation, if the G sensor detects a downhill
steepness exceeding 10%, it transmits the HDC
operation signal to the ESP HECU.

• The G sensor in sensor cluster measures the actual
road steepness. However, it may recognize a sharp
turn or rough road as a downhill road with a slope
level exceeding 10%, and the HDC may operate.
