where's the gas tank release on 2007 Cadillac Escalade

We just got our used 2007 Cadilac Escalade & can't find the release to open the gas tank door?

there is no release - go push the gas door on the left center and it will pop open or take it to the dealer and have them show you or go to full service for gas since you wasted money on an escalade you can waste more on gas
It should be in your owner's manual here is a PDF format of your owner's manual
