Bulb Replacement
The headlamp is a semi-sealed beam type which uses a replace-
able 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. Disconnect the harness connector from the back side of the
bulb.
3. Pull off the rubber cap.
4. Push and raise retaining pin to loosen it.
5. Remove the headlamp bulb carefully. Do not shake or rotate
the bulb when removing it.
6. Install in the reverse order of removal.
CAUTION:
Do not leave headlamp reflector without bulb for a long
period of time. Dust, moisture, smoke, etc. entering head-
lamp body may affect the performance of the headlamp.
Remove headlamp bulb from the headlamp reflector just
before a replacement bulb is installed.
Aiming Adjustment
When performing headlamp aiming adjustment, use an aiming
machine, aiming wall screen or headlamp tester. Aimers should
be in good repair, calibrated and operated in accordance with
respective operation manuals.
If any aimer is not available, aiming adjustment can be done as
follows:
For details, refer to the regulations in your own country.
a. Keep all tires inflated to correct pressures.
b. Place vehicle and tester on one and same flat surface.
c. See that there is no-load in vehicle (coolant, engine oil
filled up to correct level and full fuel tank) other than the
driver (or equivalent weight placed in driver's position).
CAUTION:
Be sure aiming switch is set to ª0º when performing aiming
adjustment on vehicles equipped with headlamp aiming
control.
