When in the assisted parking status, the system can take over vehicle control and change to the inactive status at any time if required by the driver on his/her initiative. The driver's active exit conditions shall be described in the system manual. Exit conditions include but are not limited to:
——controlling the steering wheel;
——controlling the brake pedal;
——controlling the gear;
——controlling the parking brake.
