🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open the trunk and access the lamp fasteners

• Open the trunk and look behind each rear lamp from inside the trunk area.
• Use the trim panel tool to gently move any trunk liner edge out of the way.
• Locate the rear lamp retaining fasteners and bulb access area.
• Work gently to avoid breaking clips.

Step 2: Remove the rear lamp assembly

• Use the 10mm socket and ratchet to remove the rear lamp nuts.
• Support the lamp with one hand as you remove the last fastener.
• Carefully pull the lamp straight rearward to release the alignment pins.
• If the lamp feels stuck, use a small flat-blade screwdriver only to gently help release the clip area.

Step 3: Replace the bulbs

• Twist the bulb socket counterclockwise by hand or with a small flat-blade screwdriver if needed.
• Remove the old bulb from the socket.
• Install the new bulb in the same position.
• Make sure it seats fully before reinstalling the socket.
• Repeat on the other side.

Step 4: Reinstall the lamp assembly

• Line up the lamp pins with the body openings.
• Push the lamp straight into place.
• Install the retaining nuts by hand first.
• Use the 10mm socket and ratchet to tighten them.
• Torque to 7.8 Nm (69 in-lbs).

Step 5: Test the lights

• Turn on the parking lights and check both taillights.
• Press the brake pedal and confirm both brake functions work.
• Check turn signals and reverse lights while you are there.
