•Clean the battery cable terminals and apply
grease to retard the formation of corrosion.
•Connect the positive (+) terminal, and then con-
nect the negative (–) terminal of the battery.
•Initial diagnosis of electronic control throttle is
performed after battery installation. Because of
this, start the engine 10 seconds or more after the
ignition switch is turned ON.
C: INSPECTION
WARNING:
•Electrolyte has toxicity; be careful of han-
dling the fluid.
•Avoid contact with skin, eyes or clothing. Es-
pecially at contact with eyes, flush with water
for 15 minutes and get prompt medical atten-
tion.
•Batteries produce explosive gases. 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 bat-
tery.
•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. This
may cause short circuit.
1. EXTERNAL PARTS
Check the battery case, top cover, vent plugs, and
terminal posts for dirt or cracks. 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 distilled water into the battery cell. Do not
fill beyond MAX level.
