🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open the glove box

• Use your hands to open the passenger-side glove box fully.
• Empty the glove box if needed so it does not fall or bind.
• Support the door as you lower it.

Step 2: Release the glove box stops

• Use a trim removal tool to gently press inward on the glove box side stops if they do not release by hand.
• Lower the glove box door carefully until it hangs down and exposes the filter access cover.

Step 3: Remove the cabin filter access cover

• Use your hands to release the access cover tabs behind the glove box.
• Pull the cover straight out so the tabs do not snap.

Step 4: Remove the old filter

• Use your hands to slide the cabin air filter out of the housing.
• Note the airflow direction arrow on the old filter before removing it.
• Match the arrow on the new filter.

Step 5: Install the new filter

• Use your hands to slide the new cabin air filter into the housing in the same direction as the old one.
• Make sure it sits flat and fully seated.

Step 6: Reinstall the access cover

• Use your hands to snap the access cover back into place.
• Make sure both tabs are locked.

Step 7: Reinstall the glove box

• Raise the glove box back into position by hand.
