spare tire??

I own a 2003 chevy trailblazer and I don't have an owners manual, how do I remove my spare tire please help, I gotta flat right now

suprising nobody told you yet...the handle is in the back on the left (On my EXT it is there) There is a little door....You put the handle together and stick it into the little hole on right side that is visible when you open the hatch. You turn the handle and it lowers the tire down....wholla!
