5. Vehicle position control function in ESP and HBA function are not in operation:
The HDC is the device to improve the engine brake effect during downhill driving on a steep hill. If the ESP
function is in operation, HDC operation is overridden.
6. Slope level exceeds 10%.
When the slope level exceeds 10%, the HDC operates until the vehicle reaches the speed value given in step (4).
When the slope level is between 10% and 20% during the HDC operation
When depressing the accelerator pedal or brake pedal, HDC system is changed to stand-by mode. When
depressing the accelerator pedal again, HDC starts its operation again. Therefore, drivers can control the vehicle
speed to a desired level by operating the accelerator pedal.
When the slope level exceeds 20% during the HDC operation
When depressing the accelerator pedal, HDC system is changed to stand-by mode. When depressing the brake
pedal, HDC continues its operation and the braking power is increased.
In this case, HECU sounds an abnormal noise and brake pedal may be very rigid, but this is a normal condition
due to HDC operation.
