Just thought I would share the procedure with all the people including myself that hate this feature.
Stop your vehicle in a flat area, apply parking brake and turn engine off.
Press VDC button and hold until disabled.Do not take finger off the button.
The light will go yellow, green and it will turn off.
Within 5 seconds of of VDC light turning off, release the button.
Within 2 seconds of releasing button, press the VDC button again and and a hill assist light will illuminate on the dash.
Turn off engine.
