📋 Before You Begin

• 🅿️ Park on level ground, set the parking brake, and switch the ignition OFF.
• 📦 Empty the glovebox so nothing falls out while it’s lowered.
• 💡 Have a flashlight ready so you can see the filter door clearly.
• Trim panel tool = plastic pry tool for panels.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open and lower the glovebox

• Open the glovebox fully.
• Use your hands to gently push in on both sides of the glovebox to clear the side “stops,” then let the glovebox swing down.
• If equipped with a small glovebox “damper” strap on the right side, use a trim panel tool to gently pop it off the glovebox pin.

Step 2: Locate the cabin filter access door

• Look behind the lowered glovebox area toward the passenger-side dash.
• Use a flashlight to find the rectangular cabin filter cover/door.

Step 3: Remove the cabin filter cover

• Release the cover tabs by hand. If tight, gently assist with a trim panel tool.
• If your cover uses fasteners, remove them with a 7mm socket and 1/4" drive ratchet or a Phillips screwdriver (use the tool that matches the fastener head).

Step 4: Remove the old filter

• Pull the old filter straight out.
• Wear nitrile gloves—old filters can be dusty.
• Note the airflow direction arrow on the old filter frame before removal.

Step 5: Install the new cabin air filter

• Match the new filter’s airflow arrow to the same direction as the old one.
• Slide the new filter into the housing until it seats flat (don’t bend or crush it).
• If it fights you, it’s likely flipped.

Step 6: Reinstall the cover and glovebox

• Reinstall the cabin filter cover and snap the tabs fully into place.
• If fasteners were removed, reinstall them with a 7mm socket and 1/4" drive ratchet or Phillips screwdriver until snug (do not overtighten).
• Reconnect the glovebox damper strap (if equipped) by pressing it back onto the pin by hand.
• Lift the glovebox up, push in the sides to clear the stops again, and close it.
