How to check and refill coolant in an Audi A2?

I just noticed my Audi A2's temperature gauge is going up. I suspect it's low on coolant, but I don't know how to check it. Can someone guide me on how to check and refill coolant in an Audi A2?

To check the coolant level in your Audi A2, first make sure the engine is completely cool. Then locate the coolant reservoir in the engine bay. It should have a MIN and MAX level marking on it. If the level is below the MIN mark, you need to refill your coolant.

To refill the coolant in your Audi A2, you will need a mixture of antifreeze and water in a 50:50 ratio. Slowly pour the mixture into the coolant reservoir until it reaches the MAX level. Be careful not to overfill.
