Replacing headlamp bulbs (aerodynamic)
1. Make sure that the headlamps are off, then open the hood.
2. Remove the bolts from the top,
side and bottom of the headlamp
assembly.
3. Pull the assembly straight out
disengaging two snap clips from the
fender.
4. Disconnect the electrical
connector by squeezing the release
tab and pushing the connector
forward, then pulling it rearward.
5. Remove the bulb assembly by
turning it counterclockwise and
pulling it straight out.
WARNING: 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.
Install the new bulb(s) in reverse order.
