Bulb Replacement
The headlamp is a semi-sealed beam type which uses a replacable
halogen bulb. The bulb can be replaced from the engine compart-
ment side without removing the headlamp body.
IGrasp 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. Press end of the retaining pin together to release bulb.
5. Remove the headlamp bulb. Do not shake or rotate the bulb when removing it.
6. Install the new bulb in reverse order of removal.
CAUTION:
I Do not leave headlamp reflector without bulb for a long
period of time as dust, moisture, smoke, etc. may enter the
headlamp body and affect the performance of the head-
lamp. Thus, the headlamp bulb should not be removed
from the headlamp reflector until just before a replacement
bulb is to be installed.
Aiming Adjustment
When performing headlamp aiming adjustment, use an aiming
machine, aiming wall screen or headlamp tester. For operating
instructions, of any aimer, it should be in good repair, calibrated and
used according to respective operation manuals supplied with the
unit.
For details, refer to the regulations in your own country.
Before performing aiming adjustment, check the following:
a. Keep all tires inflated to correct pressures.
b. Place vehicle and tester on one and same flat surface.
c. See that there is noload in vehicle other than coolant,
engine oil filled up to correct level, full fuel tank and the
driver (or equivalent weight placed in driver's position).
