🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open the cargo access area

• Open the liftgate and go to the rear corner of the cargo area where the lamp you are replacing sits.
• Remove any cargo floor panel or side trim panel covering the back of the tail lamp.
• Use the plastic trim tool to gently pop the access cover loose.

• Set the nuts aside in a safe place.
• Keep steady pressure while loosening.

Step 3: Pull the lamp housing out

• If it is a twist-lock style bulb, push in and turn it counterclockwise to release it.
• Install the new bulb into the socket and make sure it locks fully.
• Do not touch glass with bare fingers.

Step 6: Reinstall the bulb socket

• Insert the socket back into the lamp housing.
• Twist it clockwise until it locks.
• Make sure it sits flush and does not wobble.

Step 7: Reinstall the lamp housing

• Line up the locating pins with the body openings.
• Push the lamp housing straight in until it seats fully.
• Reinstall the retaining nuts using the 8mm socket, ratchet, and short extension.
• Torque to 5 Nm (44 in-lbs).
