🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open the hood and access the headlamp

• Open the hood and locate the top fasteners for the headlamp assembly.
• Use a 10mm socket and ratchet to remove the upper headlamp bolts.
• If equipped with any trim retainers near the lamp, use a trim panel tool to release them gently.
• Keep the bolts organized.

Step 2: Remove the headlamp assembly

• Pull the headlamp assembly forward carefully until you can reach the bulb sockets.
• Use your hand to support the assembly while working.
• If it feels stuck, wiggle it lightly rather than forcing it.

Step 3: Remove the turn signal bulb socket

• Find the front turn signal bulb socket at the back of the headlamp housing.
• Rotate the socket counterclockwise by hand to unlock it.
• Pull the socket straight out of the housing.

Step 4: Replace the bulb

• Twist the old bulb out of the socket.
• Install the new bulb into the socket and make sure it seats fully.
• Do not touch the glass on the new bulb with bare fingers.

Step 5: Reinstall the socket and headlamp

• Insert the bulb socket back into the headlamp housing.
• Rotate it clockwise by hand until it locks.
• Set the headlamp assembly back into place.
• Reinstall the upper bolts with a 10mm socket and ratchet.
• Torque to 4.5 Nm (40 in-lbs).

Step 6: Test the new bulb

• Turn the ignition on and activate the turn signal.
