⚠️ Safety & Precautions

• ⚠️ Turn the vehicle fully OFF and keep the key fob away from the cabin so the hybrid system cannot ready itself.
• ⚠️ Do not touch the glass part of a new bulb with bare fingers; skin oil can shorten bulb life.
• ⚠️ Work gently around the tail lamp because the plastic locating pins can crack if the lamp is pried sideways.
• ⚠️ Battery disconnect is not normally required for this bulb replacement.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open the Liftgate

• Use your hand to open the rear liftgate fully.
• Put on safety glasses and clean nitrile gloves.
• Locate the two exposed 10mm bolts on the inner edge of the tail lamp assembly.

Step 2: Remove the Tail Lamp Bolts

• Use a 10mm socket and 1/4-inch ratchet to remove the two tail lamp retaining bolts.
• Place the bolts somewhere safe so they do not fall into the body opening.
• Use light pressure only.

Step 3: Release the Tail Lamp Assembly

• Hold the tail lamp with both hands and pull it straight rearward from the vehicle body.
• If it feels stuck, use a plastic trim removal tool carefully at the outer edge to help release the locating pins.
• Do not twist the lamp side-to-side; the plastic guide pins are easy to damage.

Step 4: Remove the Turn Signal Bulb Socket

• Look at the back of the tail lamp assembly and find the rear turn signal bulb socket.
• The turn signal socket is the one for the amber flashing bulb.
• Use your gloved hand to turn the socket counterclockwise about a quarter turn.
• Pull the socket straight out of the lamp housing.

Step 5: Replace the Bulb

• Use your gloved hand to pull the old bulb straight out of the socket.
• Push the new rear turn signal bulb, amber 7440A/7440NA type straight into the socket until it seats fully.
• Do not force it. If it does not slide in, rotate it and try again.
• Never touch bulb glass bare-handed.

Step 6: Test the Bulb Before Reassembly

• Keep the bulb socket hanging safely outside the lamp opening.
• Use your hand to press the hazard warning switch on the dashboard.
• Confirm the new rear turn signal bulb flashes correctly.
• Press the hazard warning switch again to turn the flashers off.

Step 7: Reinstall the Bulb Socket

• Use your gloved hand to insert the bulb socket into the tail lamp housing.
• Turn the socket clockwise about a quarter turn until it locks.
• Make sure the socket sits flat so water cannot enter the lamp.

Step 8: Reinstall the Tail Lamp Assembly

• Line up the tail lamp locating pins with the body holes.
• Push the lamp straight forward by hand until it seats evenly against the body.
• Use the 10mm socket and 1/4-inch ratchet to reinstall the two bolts.
• Torque to 5.0 Nm (44 in-lbs).
• If you do not have a small torque wrench, tighten the bolts snug only. Do not overtighten.

Step 9: Repeat on the Other Side

• Use the same 10mm socket, 1/4-inch ratchet, and plastic trim removal tool to replace the other rear turn signal bulb if replacing in pairs.
• Replacing both sides helps keep bulb brightness and color even.
