Remove the headlamp assembly from the vehicle. If you wish to change the halogen bulb: Disconnect the electrical connector from the headlamp bulb/socket. Remove the headlamp bulb/socket retainer ring from the headlamp, by turning counterclockwise. Remove the headlamp bulb/socket from the headlamp assembly. .

1. Open the hood. 2. Remove the front air deflector. 3. Apply light pressure to the headlamp lens to hold the headlamp assembly in place while disconnecting the retainers. 4. Lift up the headlamp assembly retainers to release. Important: Note the location and position of the headlamp adjuster retainers and the locator tab. 5. Remove the headlamp assembly, pulling straight forward from the headlamp mounting panel. 6. Disconnect the wiring harness from the headlamp assembly. 7. Rotate the headlamp bulb/socket counterclockwise to release. 8. Remove the headlamp bulb/socket from the headlamp assembly, if required.
