I took a few pictures showing the tabs on the cabin air filter cover, behind the glovebox, and one showing the cabin filter housing with the door and filter removed. Mine had a few small leaves caught by the filter. The filter is marked with an arrow showing which side goes up when installed.

Gently squeeze the tabs to remove the cover. I used a finger from both hands, pressed in and wiggled the cover out. The filter media slides easily out after you hook it from below with a finger tip and wiggle it out enough to grasp it.
