You want to set off in an automatic car (hydraulic converter). What must you know?

The combination of answers provided includes important points regarding the operation of an automatic car with a hydraulic converter:

1. Holding the car with service brakes when selecting a gear is essential to prevent any unintended movement, ensuring safety. This aligns with practices outlined in German road traffic regulations to maintain control of the vehicle.

2. Moving the selector lever only when the engine has stopped is crucial for preventing damage to the transmission and ensuring smooth gear changes. This practice is part of correct driving behavior expected in Germany.

3. Raising engine revolutions to prevent stalling is important, particularly when starting from a stop. This action gives the vehicle enough power to move smoothly without stalling, which is vital for safety in traffic situations.

Understanding these rules helps drivers operate their vehicles safely and in compliance with German traffic laws, ensuring both personal safety and the safety of others on the road. Every aspect of these rules contributes to effective vehicle management and traffic safety.
