🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Access the cabin filter area

• Go to the passenger side footwell and use a flashlight to look up under the glovebox.
• If a lower trim panel blocks access, remove it (next step). If you can already see a rectangular filter cover, skip to Step 3.

Step 2: Remove the lower panel under the glovebox (if equipped)

• Use a Torx T20 screwdriver to remove the screws holding the lower panel under the glovebox.
• Use a plastic trim removal tool to gently release the clips, then lower the panel and set it aside.
• Tip: Support the panel so it doesn’t bend.

Step 3: Remove the cabin filter cover

• Locate the cabin filter housing cover (rectangular plastic cover in the HVAC box).
• Use your fingers and/or a plastic trim removal tool to release the tabs and remove the cover.

Step 4: Pull out the old cabin filter

• Slide the old filter straight out.
• Keep it level as you remove it so debris doesn’t spill into the housing.

Step 5: Install the new cabin filter

• Check the airflow direction arrow printed on the filter frame.
• Install the filter with the arrow pointing in the same direction as the old one (typically toward the rear of the car, into the HVAC box).
• Make sure it seats fully and isn’t folded or pinched.

Step 6: Reinstall the cover and panels

• Reinstall the filter cover and press until the tabs click into place.
• If removed, reinstall the lower panel: align it, snap the clips in by hand, then tighten screws using a Torx T20 screwdriver.
