I have 2006 Grand Prix How do I change head lamp?

Caution Halogen bulbs contain gas under pressure. Handling a bulb improperly could cause it to shatter into flying glass fragments. To help avoid personal injury:
Turn off the lamp switch and allow the bulb to cool before changing the bulb.
Leave the lamp switch OFF until the bulb change is complete. Always wear eye protection when changing a halogen bulb. Handle the bulb only by its base. Avoid touching the glass. Keep dirt and moisture off the bulb. Properly dispose of the used bulb. Keep halogen bulbs out of the reach of children.
Raise the hood.
Remove the headlamp assembly bolts from the upper fascia support.
Slide the headlamp assembly outward enough to release the headlamp bracket tabs from the slots in the upper fascia support.
