What is the best way to maintain the cooling system of my Audi A8?

I recently purchased an Audi A8 and have noticed that the engine temperature tends to rise quickly, especially in stop-and-go traffic. How can I properly maintain the cooling system to prevent any potential issues?

Regularly check the coolant level and top it off if necessary. It's also important to have the cooling system flushed and refilled every 30,000 miles.

Make sure the radiator and cooling fans are free of any debris or buildup. If they are clogged, it can hinder the cooling system's efficiency.

Consider upgrading your coolant to a high-performance option. This can help regulate engine temperature and prevent any overheating issues.
