How to Handle BatteryNJSC0003CAUTION:
If it becomes necessary to start the engine with a booster
battery and jumper cables,
1) Use a 12-volt booster battery.
2) After connecting battery cables, ensure that they are
tightly clamped to battery terminals for good contact.
3) Never add distilled water through the hole used to check
specific gravity.

METHODS OF PREVENTING OVER-DISCHARGENJSC0003S01The following precautions must be taken to prevent over-discharg-
ing a battery.
+The battery surface (particularly its top) should always be kept
clean and dry.
+The terminal connections should be clean and tight.
+At every routine maintenance, check the electrolyte level.
This also applies to batteries designated as ªlow maintenanceº
and ªmaintenance-freeº.
MEL041F
+When the vehicle is not going to be used over a long period of
time, disconnect the negative battery terminal.
MEL042F
+Check the charge condition of the battery.
Periodically check the specific gravity of the electrolyte. Keep
a close check on charge condition to prevent over-discharge.
CHECKING ELECTROLYTE LEVELNJSC0003S02WARNING:
Do not allow battery fluid to come in contact with skin, eyes,
fabrics, or painted surfaces. After touching a battery, do not
touch or rub your eyes until you have thoroughly washed your
hands. If acid contacts eyes, skin or clothing, immediately
flush with water for 15 minutes and seek medical attention.

5. Check depth of insulating mold from commutator surface.
+Less than 0.2 mm (0.008 in) ... Undercut to 0.5 to 0.8 mm
(0.020 to 0.031 in)
AssemblyNJSC0020Apply high-temperature grease to lubricate the bearing, gears and
frictional surface when assembling the starter.
Carefully observe the following instructions.

PINION PROTRUSION LENGTH ADJUSTMENTNJSC0020S01Clearance (QG engine models)NJSC0020S0101With pinion driven out by magnetic switch, push pinion back to
remove slack and measure clearance ª!º between the front edge
of the pinion and the pinion stopper.
Clearance ª!º:
Refer to SDS (SC-34).
MEL140L
Movement (YD engine models)NJSC0020S0102Compare movement ª!º in height of pinion when it is pushed out
with magnetic switch energized and when it is pulled out by hand
until it touches stopper.
Movement ª!º:
Refer to SDS (SC-34).

Bulb ReplacementNJEL0015The headlamp is a semi-sealed beam type which uses a replace-
able halogen bulb. The bulb can be replaced from the engine com-
partment 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. Pull off the rubber cap.
3. Disconnect the harness connector from the back side of the
bulb.
4. Remove the bulb retaining ring.
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 headlamp body
may affect the performance of the headlamp. Remove head-
lamp bulb from the headlamp reflector just before a replace-
ment bulb is installed.
Aiming AdjustmentNJEL0016For details, refer to the regulations in your own country.
Before performing aiming adjustment, check the following.
1) Keep all tires inflated to correct pressures.
2) Place vehicle on flat surface.
3) 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).
SEL984W
CAUTION:
Be sure aiming switch is set to ª0º when performing aiming
adjustment on vehicles equipped with headlamp aiming con-
trol.
