🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open the hatch and find the access panel

• Open the rear hatch.
• Look behind the rear interior trim near the taillight area.
• Use a trim panel tool to gently pop off the access cover.
• Work slowly to avoid breaking clips.

Step 2: Remove the bulb holder

• Reach into the opening and locate the bulb socket at the back of the taillight housing.
• Use your hand to twist the socket counterclockwise and remove it.
• If it is stuck, use a flathead screwdriver very gently for extra turning help.

Step 3: Replace the bulb

• Pull the old bulb straight out of the socket.
• Push the new bulb into the socket until it seats fully.
• Do not touch the glass if the bulb has a glass envelope. Use gloves.

Step 4: Reinstall the socket

• Line up the bulb holder with the taillight housing.
• Push it in and twist clockwise until it locks.
• Torque: Hand-tight only; no published torque spec for the bulb socket.

Step 5: Repeat on the other side

• Follow the same steps on the opposite taillight.
• Replace both bulbs together so brightness matches.

Step 6: Reinstall the access cover

• Snap the access cover back into place by hand.
• Make sure it sits flush and all clips are seated.
