Open the glove box. On the right hand side, there's a lever which slows the descent of the glovebox door so it doesn't just flop down. Disconnect it by pushing the part connected to the door straight back. It'll pop out.

Then, put your hands on the two sides of the glovebox "box" right where it touches to top of the opening in the dash. Squeeze inwards and pull forward; the box will slide right out of the dash and pivot towards the floor (make sure you empty the contents of the glovebox or everything will dump out onto the floor. I know...).

Then look inside the opening. There is a rectangular hatch with tabs on either side. Push those tabs towards each other and the tray with the CAF in it slides right out.

Pull out old, dirty filter. Replace with new, clean filter. Be sure to align air flow arrows so that the arrow points down. Slide tray back into opening. Installation is the reverse or removal.
