Here is the link from Edmunds.com on what maintance has to be done during 5,000 miles interval for Mazda3, but you will have to submit the information to get exact right information. Very good way to keep the your car well mainted, hope it helps. Good luck

i just checked that out, it really wasnt very useful, you can get that same info from Mazda or the dealership where you bought the car

 

Yes, you are correct, I am sure some of it is in the manual too, but it will help me to do the maintance and check better cause i do everything myself, the closest mazda dealer is 10 miles from me, and i am too laze to drive there to do it all and pay their labor costs where i can do it myself, anyways, if it doesn't help you at least someone else like me may use it.
