CHECKING BATTERY CONDITION
Precautions
CAUTION
BATTERY PRECAUTIONS
The battery produces flammable and explosive hydrogen gas.
Do not cause a spark by contacting the battery terminals
with tools.
Do not smoke or light a match near the battery.
The electrolyte contains poisonous and corrosive sulfuric acid.
Avoid contact with eyes, skin or clothes.
Never inhale or swallow electrolyte.
Wear protective safety glasses when working near the
battery.
Keep children away from the battery.
EMERGENCY MEASURES
If electrolyte gets in your eyes, flush your eyes with clean
water for at least 15 minutes and get immediate medical
attention. If possible, continue to apply water with a sponge
or cloth while traveling to the medical office.
If electrolyte gets on your skin, thoroughly wash the
contacted area. If you feel a pain or burn, get medical
attention immediately.
If electrolyte gets on your clothes, there is a possibility of its
soaking through to your skin, so immediately take off the
exposed clothing and follow the procedure above, if
necessary.
If you happen to swallow electrolyte, drink a large quantity
of water or milk. Follow with milk of magnesia, beaten raw
egg or vegetable oil. Then go immediately for emergency
help.

Checking battery exterior
64L009
1
Terminals 2
Hold down clamp
Check the battery for corroded or loose connections, cracks, or
loose hold down clamps.
1. If the battery is corroded, wash it off with a solution of warm
water and baking soda. Coat the terminals with grease to prevent
further corrosion.
2. If the connections are loose, tighten the clamp bolts but do not
overtighten.
3. Tighten the hold down clamp only enough to keep the battery
firmly in place. Overtightening may damage the battery case.
NOTICE
Make sure the engine and all accessories are turned off
before performing maintenance.
When checking the battery, remove the ground cable first and
reinstall it last.
Be careful not to cause a short circuit with tools.
Take care no solution gets into the battery when washing it.

Checking battery fluid
There are 2 types of batteries: maintenance type and
non maintenance type.
A non maintenance battery has ”MAINTENANCE FREE
BATTERY” on its top. A maintenance type battery does not have
such indication.
Maintenance type battery
Check the fluid condition by the fluid level lines on the side of the
battery. Or if the battery has a hydrometer on its top, you can also
check the hydrometer.
Non maintenance battery
Check the battery condition by the hydrometer on the top of the
battery.(a) Checking by the fluid level lines (Maintenance type battery
only)
64L063
1
Upper line 2
Lower line
The fluid (electrolyte) level must be between the upper and lower
lines.
When checking the fluid level, look at all six cells, not just one or
two.
If the level is lower than the lower line, add distilled water. (See
”Adding distilled water” on page 257.)

Adding distilled water
(Maintenance type battery only)
64L062

Low 2
O.K.
1. Remove the vent plugs.
2. Add distilled water to cells needing fluid.
If the side of your battery is covered, check the water level by looking
down directly above the cell as illustrated above.
3. Retighten the vent plugs securely.
NOTICE
Do not overfill the cells. Excess electrolyte could squirt out
of the battery during heavy charging, causing corrosion or
damage.
Use a cover on the battery for longer life.
BATTERY RECHARGING
PRECAUTIONS
During recharging, the battery is producing hydrogen gas.
Therefore, before recharging:
1. Maintenance type batteries Remove the vent plugs.
2. If recharging with the battery installed on the vehicle, be sure to
disconnect the ground cable.
3. Make sure the power switch on the recharger is off when
connecting the charger cables to the battery and when disconnecting
them.
CAUTION
Always charge the battery in an unconfined area. Do not
charge the battery in a garage or closed room where there
is not sufficient ventilation.
Non maintenance batteries: Only do a slow charge (5 A or
less). Charging at a quicker rate is dangerous. The battery
may explode causing personal injuries.
Maintenance type batteries: Be sure to remove the vent
plugs before recharging.
NOTICE
Never recharge the battery while the engine is running. Also,
make sure all accessories are turned off.

CHECKING THE CARTRIDGE TYPE
FUSES
64L016-3
1
Good 2
Melted
If the headlights or other electrical components do not work and
the blade type fuses are O.K., check the cartridge type fuses. If
any of the cartridge type fuses are blown, they must be replaced.
If there is an overload in the circuits from the battery, the fuses are
designed to blow before the entire wiring harness is damaged.
NOTICE
Before replacing the fuses, have the cause of electrical overload
determined and repaired by your Lexus dealer.
CAUTION
Always use a genuine Lexus fuse or equivalent for
replacement. Never install an ordinary wire even for a
temporary fix. This may cause extensive damage and possibly
a fire.
