What is the most efficient way to check the battery level in an Audi A2?

I can't seem to find a clear indicator for the battery level in my Audi A2. Is there a specific button or display I can reference for this information?

You can check the battery level by accessing the onboard computer. Navigate to the car settings menu and look for the battery icon. It will display the current voltage.

Another way to check the battery level is by using a multimeter. Connect the multimeter to the battery terminals and it will give you an accurate reading of the voltage.
