What should I be aware of when using an adaptive cruise control system?

Your answer included all relevant aspects of using an adaptive cruise control system.

1. Remaining constantly attentive is crucial, as even with advanced technology, the driver must always be ready to take control if necessary. This aligns with the principle of keeping a safe distance and being aware of surrounding traffic conditions outlined in German road traffic regulations.

2. The system's performance can indeed be compromised in adverse weather conditions like heavy rain or snowfall. This is important because safety systems are designed for ideal conditions, and variability in weather can affect vehicle behavior and sensor readings.

3. The ability to override the system using the accelerator or brake pedal is essential. It ensures that the driver can react promptly to unexpected situations, highlighting the importance of maintaining control over the vehicle at all times.

Understanding and acknowledging all these points helps ensure safe driving practices and compliance with German traffic laws.
