How do I properly maintain my Audi A2's engine cooling system?

I recently noticed that my Audi A2's engine temperature has been rising and I'm concerned about potential overheating issues. What steps should I take to properly maintain my engine cooling system?

First, check the coolant levels and make sure they are at the proper level. If they are low, top them off with a 50/50 mixture of coolant and water. Also, make sure to regularly flush and replace your coolant according to the manufacturer's recommendations.

Be sure to check for any leaks in the cooling system, such as from the radiator or hoses. If you notice any leaks, they should be repaired immediately to prevent further issues.
