Electrical System

Fuses

The fuse box (1) is accommodated
in the R-H side floor space.
A table in the fuse box cover (2)
depicts all the protected electrical
units.
Fuses must not be repaired or
bridged.
Spare fuses for emergencies
(observe amperage and color) are
stowed with the tools.
Diagnose the cause of a short cir­
cuit before replacing a burned-out
fuse.

Battery

The battery is located in the trunk.
Replenish with distilled water
approximately every 4 weeks, and
more often in summer and in hot
zones.
Do not use metal funnels and do
not perforate the diaphragm of the
battery overfill protection.
The battery is filled to the maximum
level when the water level in the
cell filling cham ber stops going
down.
If battery acid is to be extracted for
battery diagnosis purposes,
perforate the diaphragm with the
hydrom eter or the tube attached
to it.
Coat battery terminal clamps with
acidproof grease. Keep battery
clean and dry.
Only tow vehicle with the battery
connected.
Only charge battery with a battery
charger when it is disconnected
from the vehicle electrical circuit.
Note:
While the engine is running the bat­
tery terminal clamps must not be
loosened or detached as otherwise
the alternator and other electronic
units would be damaged.
