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

Your answer correctly identifies all crucial aspects of using an adaptive cruise control system.

1. Remaining constantly attentive is vital, as the driver is ultimately responsible for safe driving, even when the system is engaged. This aligns with the German road traffic regulations that emphasize driver responsibility.

2. Awareness that the system can be affected by heavy rain or snow is important because these conditions can impair sensor functionality, potentially leading to unsafe driving situations.

3. Knowing that activating the accelerator or brake pedal can override the system is crucial, as it reinforces the driver's control over the vehicle at all times.

Recognition of all these factors is necessary to ensure safety while utilizing advanced driving assistance systems.
