Halogen bulbs have pressurized gas inside and
can burst if you drop or scratch the bulb. You or
others could be injured. Be sure to read and
follow the instructions on the bulb package.
To replace the headlamp bulb:
1. Open the hood.
2. Push in on both sides of the electrical connector. Pull
up and rearward, to disconnect it from the bulb. The
plastic clip on the electrical connector may need to
be lifted gently with a screwdriver.
