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.

CHECKING THE CARTRIDGE
TYPE FUSES
64G019±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.

ADDING WASHER FLUID
64G009
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.
