🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open the glove box

• Use your hands to open the glove box fully.
• Empty the glove box if it is heavy.
• Go slow to avoid breaking tabs.

Step 2: Release the glove box stops

• Use your hands to gently squeeze both sides of the glove box inward.
• This clears the glove box stops so the box can hang down farther.
• If needed, use a trim tool or small flat-blade screwdriver very carefully to help lift the side tabs.

Step 3: Remove the cabin filter cover

• Look behind the glove box for the rectangular cabin filter access cover.
• Use your hand to unclip the cover and remove it.
• Keep steady pressure on the clips.

Step 4: Remove the old filter

• Slide the old cabin air filter straight out.
• Pay attention to the airflow arrow on the filter before removing it.
• Use a flashlight if the area is dark.

Step 5: Install the new filter

• Compare the new filter to the old one to make sure they match.
• Insert the new filter in the same direction as the airflow arrow.
• Push it fully into the housing by hand.

Step 6: Reinstall the cover and glove box

• Snap the filter cover back into place by hand.
• Lift the glove box back up and push the side stops back into position.
• Close the glove box and make sure it opens and closes normally.
