Bulb Replacement
The headlamp is a semi-sealed beam type which uses a
replaceable halogen bulb. The bulb can be replaced from the
engine compartment side without removing the headlamp body.
Grasp only the plastic base when handling the bulb. Never
touch the glass envelope.
1. Disconnect the battery cable.
2. Turn the bulb retaining ring counterclockwise until it is free
from the headlamp reflector, and then remove
it.
3. Disconnect the harness connector from the back side of the
bulb.
4. Remove the headlamp bulb carefully. Do not shake or rotate
the bulb when removing it.
5. Install in the reverse order of removal.
CAUTION:
Do not leave the bulb out of the headlamp reflector for a
long period of time as dust, moisture, smoke, etc. may
enter the headlamp body and affect the performance of
the headlamp. Thus, the headlamp bulb should not be
removed from the headlamp reflector until just before a
replacement bulb is to be installed.
