you have 7.5k, 15k, and 30k check ups i believe. the 7.5 is oil and oil filter. the 15k is oil again and other stuff like tranny fluid should be checked, brake fluid, wind shield washer fluid, brake thickness, power steering fluid. it is basically all of your fluids but i add a valve check in there as well. and the 30k is the 15k plus like check belts or something. the 90k is for the water pump and timing belt i believe.
