Is it OK to have over-full fluid levels?

Just purchased 2009 Sienna but all the fluid levels (coolant, powersteering, oil, and trans.) are overfull. The dealer says this is alright but I feel uneasy about it. Anyone know if any harm will happen?

Tanks for any and all feedsback.

No - The oil, or fluid pressure is too much pressure, and cause fluid leaks.
