How do I properly check and refill the coolant in my Audi A2?

I recently noticed that my Audi A2's coolant level is low. However, I'm unsure of how to properly check and refill it. Can someone provide me with step-by-step instructions?

First, make sure your car is cooled down and parked on a flat surface. Then locate the coolant reservoir, which is usually a semi-transparent plastic container with a cap labeled 'Coolant'. Open the cap and check the level of the coolant. If it's below the 'Min' line, you'll need to refill it. Using a funnel, slowly pour a 50/50 mixture of antifreeze and distilled water until the level reaches the 'Max' line. Be sure to clean up any spills and securely close the cap.

If you notice any leaks or discoloration in your coolant, it may be time to replace it entirely. Refer to your Audi A2's manual for the proper type and amount of coolant to use. It's important to regularly check and maintain your coolant levels to prevent engine damage.
