What is the best way to maintain the cooling system in an Audi A2?

I recently purchased an Audi A2 and want to make sure I take proper care of the cooling system. What steps should I take to maintain it?

Regularly check and replace the coolant according to the manufacturer's recommendations to prevent overheating and potential engine damage.

Make sure to flush and refill the coolant system every 2-3 years to remove any built up debris that could cause clogs or blockages.
