🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open and support the glove box

• Use your hand to open the glove box fully.
• Remove all contents so nothing falls out.
• Let the glove box drop down carefully until it stops.

Step 2: Release the glove box stops

• Use a trim panel tool or your fingers to gently squeeze the sides of the glove box inward.
• This lets the stops clear the opening and allows the glove box to swing down farther.
• Go slow to avoid cracking the plastic.

Step 3: Remove the cabin filter cover

• Use your hand to find the filter access cover behind the glove box opening.
• Release the retaining tabs and remove the cover.

Step 4: Remove the old cabin air filter

• Use your hand to slide the old filter straight out.
• Note the airflow arrow direction on the old filter before removal.
• Keep the dirty filter level to avoid dropping debris.

Step 5: Install the new cabin air filter

• Use your hand to slide the new filter into the slot.
• Match the airflow arrow to the direction marked on the old filter or HVAC housing.
• Push the filter in fully until it sits flush.

Step 6: Reinstall the cover and glove box

• Use your hand to reinstall the filter cover until it clicks into place.
• Lift the glove box back up and press the sides inward if needed so it clears the stops.
• Close the glove box fully.
