Note: Overview of HDC Operation
HDC (Hill Descent Control) System
The HDC system is an automatic descent control device that allows the vehicle to automatically decelerate to
about 7 km/h with increment of 0.1G, on steep roads (inclination 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)
The HDC does not have a separate sensor for the input signal and detects
the inclination of hills by using the G sensor (acceleration sensor) in the
sensor cluster.
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 inclination exceeding 10%, the ESP’s HDC function
operates. When this occurs, the green HDC indicator goes off along with a
loud operation noise.
When pressing the HDC switch, the green HDC
indicator on the instrument panel comes on, and
when the HDC operates, the green HDC indictor
blinks with 0.5 seconds of interval. The G Sensor within the sensor cluster detects
the inclination of driving roads. When the HDC
switch is in operation, if the G sensor detects a
downhill inclination exceeding 10%, it transmits
the HDC operation signal to the ESP HECU.

* For the specific information, please refer to the ABS/
ESP section.
• The G sensor within the sensor cluster
measures the actual road inclination.
However, it may recognize a sharp turn or
rough road as a downhill with a inclination
exceeding 10%, and the HDC may operate.
