That's all total bullsh*t. Do what your manual says. I bet it says nothing more than change the oil (as you normally do), change air filter, probably not even change coolant at this point, inspect belts, etc. those 30k maintenances are a huge scamtastic ripoff.
Stealerships always upsell and foment fear about a future without their expensive and useless maintenance packages, but the manual will give you the truth.
