how do i get the cd out of the machine?

I have a 2006 Chevy Equinox thay will not eject the cd when I push the button. This is only the second cd i have played and i am really at a loss. Cant figure out how to get to the inside of the player to check it out so i need help on how i should go about getting a cd out of the player?
