You can click on each indicator button to view more detail: 

The first indicator light is the notifications list. You will be able to see when you have uncertified logs, unidentified logs, etc.

The second indicator light is the malfunction/diagnostics list. It will be yellow if it is a data diagnostic or red if there is a malfunction present. If you click the button, it will show more detail and what needs done to correct it.

The third indicator light is the bluetooth icon. It will be green if you are properly connected to bluetooth and red if you are not. If you click on the button, it will also show information such as VIN number, app version, etc.
