The AH3 requires the oil service much more often because the torque converter is replaced by an electric motor for the hybrid system. The motor generates a lot of heat which can cause the fluid to degrade at a more rapid rate.
I'd change it every 60,000 miles or so for the gas version, and stick to the books for the hybrid.
