Coreect, the 2006 models don't illuminate unless there is someone in the seat that the system doesn't feel is capable of handling of airbag deployment safely.
It's like my old Accord with side airbags. The light stayed off no matter what unless I had something on the seat that shifted weight to the side. Once a re-adjustment of the items on the seat was made, the light went out.
