⚠️ Safety & Precautions

• ⚠️ Turn the car OFF fully and keep the key fob away from the vehicle so it can’t “wake up” unexpectedly.
• ⚠️ Keep fingers clear of the cooling fan area; it can run automatically on hybrids.
• ⚠️ Do not blow compressed air into the intake tube; debris can be pushed into the engine.
• ⚠️ Battery disconnect is not required for this job.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Locate the air filter housing

• Use the flashlight to find the air box near the front/side of the engine bay with a big rubber intake tube attached.

Step 2: Unclip the air box cover

• Release the metal spring clips holding the air box lid down.
• If a clip is stuck, gently pry it with a flathead screwdriver (go slow so you don’t crack the plastic).
• Tip: Push the lid down slightly, then unclip.

Step 3: Open the air box and remove the old filter

• Lift the air box lid up just enough to access the filter (you usually don’t need to remove the intake tube).
• Pull the old filter straight out.
• Use a clean shop towel to wipe loose dust from the inside of the air box.

Step 4: Install the new filter correctly

• Place the new filter into the lower air box tray.
• Make sure the filter’s rubber edge (gasket) seats evenly all the way around—no gaps or folds.
• Tip: If it won’t sit flat, it’s misaligned.

Step 5: Close and secure the air box

• Lower the air box lid back into place.
• Re-engage all the clips by hand; use the flathead screwdriver only if needed to help guide a stubborn clip.
• Do a quick visual check that the lid is fully closed on all sides.

✅ After Repair
