Question about required maintenance

[gm830]

I bought my car in January of this year and I paid extra for this warranty maintenance package thingy where I just bring my car in and don't have to pay for maintenance service for 5 years...When the dealer was trying to sell it I thought he had showed me this list of required maintenance at like 6mo, 9mo, 12mo and so on...But I was looking through the coupon book I received for it to see when I should take it in (last time was July) and the book is only for every 5,000 mi, is that correct or should I be taking it in more often than that? The sticker for next service that they left on my car after the July visit says to bring it in again in october but I didn't receive any scheduled maintenance reminder in the mail like last time and then I looked at my coupon book and it said every 5,000 so I'm a little confused and I want to make sure that my Smurf is getting everything it needs. For anyone else who bought that package do they do the oil change when you take it in too? Oil is also every 5,000mi right?? Thanks!
