How to properly maintain the coolant level in an Audi A2?

I recently noticed that the coolant level in my Audi A2 has been dropping, causing the temperature to rise. How do I properly maintain the coolant level to avoid the risk of overheating or engine damage?

Regularly check the coolant level in your vehicle using the designated reservoir. If the level is low, top it up with a mix of equal parts of antifreeze and water.

Make sure to check for any leaks in the cooling system, such as hoses or the radiator. These could be the cause of the dropping coolant level and should be addressed promptly.

Consider getting a coolant flush service at a trusted mechanic to ensure the system is functioning properly and to remove any contaminants or debris that may be causing the drop in coolant level.
