How do you change the cabin filter in a 2011 Toyota Highlander?

To change the cabin filter in a 2011 Toyota Highlander, first, locate the filter compartment, which is behind the glove box. Open the glove box and remove the damper arm to allow it to drop down fully. Then, unclip the sides of the glove box to access the filter housing. Slide out the old cabin filter, insert the new one (ensuring the airflow direction matches the markings), and reassemble the glove box.
