The cabin air filter is located in the engine compartment, just below the windshield on the passenger side. Open the hood and ensure it is securely supported.

Remove the plastic panel under the windshield to access the cabin air filter housing: then unclip the cover, slide out the old filter, and eliminate any debris present. Install the new filter, ensuring it is oriented correctly for airflow, then reposition the cover and the plastic panel.

It is also recommended to sanitize the cabin with a suitable spray.
