Standard fitment is the Electronic Parking Brake. It is engaged or dis-engaged by the console switch. It also dis-engages when ECU feels engine torque at a certain clutch position, i.e. you're just biting the clutch and not just at that clutch position in neutral. It does not engage when engine is stopped.
'Parking Brake Fault' can be caused by something as simple as pulling the switch too slowly (i.e. neither up nor down...) or something as expensive as the control unit. A fault scan would tell you.
The Hill Hold Assist is an optional extra. It engages when it senses the car coming to rest when there is pressure on the footbrake. It will not activate if the car rolls to a stop. It doesn't promote wear on the handbrake mechanism because rather than operating the parking brake each time, the ABS system holds hydraulic pressure in the system therefore all four brakes hold the vehicle. It dis-engages much more quickly than the parking brake so driving off is much smoother.
