It is used for the second item of the 6 operation conditions of the ABS/ESP’s HDC function. Please refer to the ABS/
ESP section for the specific information related to the HDC.
1) HDC Operation switch ON
2) Forward/Reverse Shifting lever location
Manual transmission: operates in the 1st gear or reverse gear position (does not operate in the neutral position).
Automatic transmission: possibly operates except in the P (parking) or N (neutral) position.
3) When not depressing the accelerator pedal or brake pedal.
4) The vehicle speed is above 7 km/h (based on the automatic transmission/4H drive mode).
5) The ESP’s vehicle position control function and HBA function are not in operation.
The HDC is added to aid drivers when driving down the hill, but when any basic function of the ESP is in
operation prior to the HDC system operation, the ESP takes priority over the HDC.
6) The inclination of the driving road exceeds 10%.
When the inclination of the driving road exceeds 10%, the HDC operates until the vehicle reaches the speed
condition given in step 4).

When the Inclination is 10% ~ 20% During the HDC Operation
When depressing the accelerator pedal or brake pedal, it converts to the stand-by mode, and when depressing
the accelerator pedal again, the HDC operates again. Therefore, driver may maintain a desired speed by repeat-
ing this depressing and releasing process of the accelerator pedal.
When the Inclination Exceeds 20% During the HDC Operation
When depressing the accelerator pedal, it converts to the HDC operation stand-by mode. When depressing the
brake pedal, the HDC operation state is maintained and the braking power is enhanced.
In this case, the HECU emits an abnormal noise and the brake pedal may feel very rigid, but this is a normal
occurrence resulted from the HDC operation.
2. Detects the position of the shifting lever for the HDC operation among ABS/ESP functions.
• The vehicle with the manual transmission does not have a separate device or switch that detects the 1st
gear. It only detects the forward/reverse direction of the vehicle through the back-up light switch and the
neutral switch, and cannot solely detect the 1st gear position. The reason for noting the 1st gear above, though
the HDC also operates in the 2nd gear position, is because the engine may turn off during the HDC operation
process. You may face a very dangerous situation if the engine turns off at a steep hill.
• The HDC aids the slowdown of the vehicle when driving down a steep hill and cannot sufficiently decelerate
only with the engine brake. Thus, a driver must operate the HDC only in the 1st gear when driving a vehicle
with the manual transmission.
