1. Make sure that the headlamps are off and open the hood.
2. Remove the four bolts from the
top, side and bottom front of the
headlamp assembly.
3. Pull the assembly straight out
disengaging two snap clips to

4. Disconnect the electrical
connector by squeezing the release
tab and pushing the connector
forward and then pulling it

WARNING: Handle a halogen headlamp bulb carefully and keep

bulb to break the next time the headlamps are operated.
Install the new bulb(s) in reverse order.
