1. Precaution

Before disassembling or reassembling parts, always
disconnect battery ground cable. When repairing
radio, control modules, etc. which are provided with
memory functions, record memory contents before
disconnecting battery ground cable. Otherwise, these
contents are cancelled upon disconnection.

Reassemble parts in reverse order of disassembly
procedure unless otherwise indicated.

Adjust parts to specifications contained in this
manual if so designated.

Connect connectors and hoses securely during
reassembly.

After reassembly, ensure functional parts operate
smoothly.
CAUTION:

Airbag system wiring harness is routed near the
electrical parts and switch.

All Airbag system wiring harness and connectors
are colored yellow. Do not use electrical test equip-
ment on these circuit.

Be careful not to damage Airbag system wiring har-
ness when servicing the ignition key cylinder.

B: INSPECTION
1. BATTERY
1) External parts
Check for the existence of dirt or cracks on the battery
case, top cover, vent plugs, and terminal posts. If
necessary, clean with water and wipe with a dry cloth.
Apply a thin coat of grease on the terminal posts to prevent
corrosion.
2) Electrolyte level
Check the electrolyte level in each cell. If the level is below
MIN LEVEL, bring the level to MAX LEVEL by pouring dis-
tilled water into the battery cell. Do not fill beyond MAX
LEVEL.
WARNING:

Electrolyte has toxicity; be careful handling the
fluid.

Avoid contact with skin, eyes or clothing. Especially
at contact with eyes, blush with water for 15 minutes
and get prompt medical attention.

Batteries produce explosive gasses. Keep sparks,
flame, cigarettes away.

Ventilate when charging or using in enclosed space.

For safety, in case an explosion does occur, wear
eye protection or shield your eyes when working near
any battery. Never lean over a battery.

Do not let battery fluid contact eyes, skin, fabrics, or
paint-work because battery fluid is corrosive acid.

To lessen the risk of sparks, remove rings, metal
watch-bands, and other metal jewelry. Never allow
metal tools to contact the positive battery terminal and
anything connected to it while you are at the same time
in contact with any other metallic portion of the vehicle
because a short circuit will be caused.
