Park the vehicle in a safe location and ensure it is powered off.

2. Remove the Glove Box

Open the glove box and remove any contents.
Locate the stop arm on the right side of the glove box; push it inward to allow the glove box to drop down fully.

Locate the cabin air filter housing behind the glove box.
Remove any retaining clips or screws securing the cabin air filter cover.
Gently pull the cover off to expose the cabin air filter.

Carefully remove the old cabin air filter from its housing.
Take the new cabin air filter out of its packaging and ensure it is oriented correctly (check for airflow direction arrows).

5. Reassemble the Components

Reattach the cabin air filter cover, securing it with retaining clips or screws.
Reinstall the glove box by aligning it with the dashboard and securing it in place.
