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

I recently purchased a used Audi A2 and have noticed that the coolant level is quite low. How often should I check and refill the coolant and what kind of coolant should I use? Also, are there any other steps I should take to ensure the proper functioning of the coolant system?

As with any car, it is important to regularly check and maintain the coolant levels in your Audi A2. You should check the level at least once a week and top it off as needed. As for the type of coolant, it is recommended to use a mixture of 50% coolant and 50% distilled water. Make sure to use a high-quality, long-life coolant that is compatible with your car's engine.
