Which driver assistance systems do you have to manually activate to assist you in specific situations?

The combination you selected (1 and 2) is correct because both the active park assist and adaptive cruise control (ACC) are systems that require manual activation by the driver in specific situations. Active park assist helps with parking, but the driver must activate it when they intend to park. Similarly, the adaptive cruise control system needs to be engaged by the driver to maintain a set speed and adjust automatically to traffic conditions.

The emergency brake assist, on the other hand, is a system that automatically activates in emergencies to help prevent collisions, and it operates without manual input from the driver. Understanding the difference between these systems is crucial for safe driving in Germany, where proper use of driver assistance technologies contributes to road safety and compliance with traffic regulations.
