Remove the cover on the right side of the dashboard beside the glove box. Inside, you will see the damper for the glove box. Disconnect it from the glove box allowing you to open the glove box fully. Open the glove box and push in the tabs on each side that keep the box locked into the dashboard. Behind the glove box you will see the access panel for the cabin filter.

The Owner's Manual has the instructions in the Section 6 - do it yourself.
