How do I check the coolant level in an Audi A6?

I noticed my Audi A6's engine temperature rising and want to make sure the coolant level is sufficient. Can someone explain the process for checking and adding coolant in this specific car model?

To check the coolant level in an Audi A6, start by locating the coolant reservoir which can be found near the radiator. Then, remove the cap and use a flashlight to check the level, which should be between the "MIN" and "MAX" marks. If it's low, use a 50/50 mixture of coolant and water to top it off.
