Lights Replacing HID headlamp bulbs (if equipped) The low beam headlamps on your vehicle use a "high intensity discharge" source. These lamps operate at a high voltage. The bulb is NOT replaceable. When the bulb is burned out, the lamp assembly must be replaced by your dealer or a qualified technician. Replacing front parking lamp/turn signal bulbs 1. Make sure the headlamp control is in the OFF position. 2. Open the hood. 3. At the back of the headlamp lens, remove the three headlamp assembly bolts. 4. Pull the headlamp assembly forward slightly to expose the electrical connectors. 5. Rotate the bulb socket counterclockwise and remove. 6. Pull the bulb straight out of the socket and push in the new bulb. 7. To complete installation of the parking lamp/turn signal assembly, follow the removal procedures in reverse order. Replacing foglamp bulbs Handle a halogen headlamp bulb carefully and keep out of children's reach. Grasp the bulb only by its plastic base and do not touch the glass. The oil from your hand could cause the bulb to break the next time the headlamps are operated. 108
