Accessing Fuel Computer in 08' Mazda3

I just got a brand new 08' madza3 s Sport a few days ago and i was looking through the manual and found there is a fuel computer inside the car. It says to push the "info" button but I don't have one. Instead I have the ":00" button. I did some research and found that if you hold the CD and AM/FM buttons then turn the car on the "DIS ON" will appear in the dash after the "HELLO" and then if you restart you car again the fuel thing will come up. I tried that method out and it didn't work. I held the CD and AM/FM buttons and everything. Anyone have any idea on how to activate it in the O8' non-hatchback models? I would REALLY like this feature.
