What is the best way to maintain the hybrid engine of an Audi A2?

I recently purchased a used Audi A2 with a hybrid engine and I want to make sure I am properly maintaining it. What are the recommended maintenance tasks and schedules for the hybrid engine of this car model?

The most important maintenance tasks for the hybrid engine of an Audi A2 are regular oil changes and keeping the battery charged. Schedule an oil change every 3,000 miles and use the manufacturer recommended oil.

In addition to regular oil changes, it is also important to check and replace the air and fuel filters every 20,000 miles. This will help keep your engine running smoothly and efficiently.

Don't forget about the electrical components of your hybrid engine. Inspect the battery terminals and cables for any signs of corrosion and replace them if necessary. You should also have the battery's state of charge tested every 12 months.
