You need to access it from the passenger area of the dash. IF you open the glove and press in on the left you can pull the glove comparment away to access the tab the arrow is pointing at, release it.

Under the dash there will be 4 screws that hol a panel up. remove and lower the panel. The tab you released has a small bolt in it toward the back, remove it and lower that piece (#1 on 1st drawing) that the tab is attached to. Pull down on the filter and put the new one in. reassemble
