CHECKING BATTERY CONDITION
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.

ELECTRICAL COMPONENTS
195 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.
Hold-down clamp
Terminals
1. Check the battery for corroded or loose connections,
cracks, or loose hold-down clamps.
a. 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.
b. If the connections are loose, tighten the clamp bolts − but
do not overtighten.
c. 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.
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.

NOTICE:
Your Lexus has a maintenance free battery. Do not
refill the battery with water.
Use a cover on the battery for longer life.
BATTERY RECHARGING
PRECAUTIONS
During recharging, the battery is producing hydrogen
gas.
Therefore, before recharging:
1. If recharging with the battery installed on the vehicle, be
sure to disconnect the ground cable.
2. 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.
Only do a slow charge (5 A or less). Charging at a
quicker rate is dangerous. The battery may explode
causing personal injuries.
NOTICE:
Never recharge the battery while the engine is running.
Also, be sure all accessories are turned off.

Type A
GoodBlown
Type B
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.
ADDING WASHER FLUID
If the washer tank becomes nearly empty, add washer
fluid.
You may use plain water as washer fluid. However, in cold
areas where temperatures range below the freezing point, use
washer fluid containing antifreeze. This product is available at
your Lexus dealer and most auto parts stores. Follow the
manufacturer’s directions for how much to mix with water.
NOTICE:
Do not use engine antifreeze or any other substitute
because it may damage your vehicle’s paint.
