Every GM vehicle made in the past few years has an anti-siphoning valve at the bottom of the filler neck. There is a cone shaped tool that you can put onto a hose, to bypass, but your friendly neighbor kids won't have one.
I can't verify that the H3 has one, but I can't see why it would not when Saturns, and other GM vehicles have this device.
