Do you have a Mac OS X?
Maybe you just need to reinstall the driver. Download it through the following link:

Let me know if it does not work and tell me what OS version you are using. Click on the Apple menu and select About This Mac to get the version.

Thanks.

I suggest that you get the instructions manual, you will find what the icon indicates there... you can also visit a local dealership and have a few chat with the mechanic. I'm sure they will not charge you for a very basic question.
