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.

BATTERY RECHARGINGPRECAUTIONS
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, make sure all accessories are turned off.
CHECKING AND REPLACING THE BLADE TYPE FUSES

1. Turn the ignition switch off and open the fuse box lid.
Determine which fuse may be causing the problem. The lid of
the fuse box shows the name of the circuit for each fuse.

2. Make sure the inoperative component is turned off. Pull
the suspected fuse straight out with the pullout tool and
check it. If it has blown, push a new fuse into the clips.

Good Blown
a. Look carefully at the fuse. If the thin wire is broken, the fuse
has blown. If you are not sure or if it is too dark to see, try
replacing the suspected fuse with one of the same value that
you know is good.
b. Only install a fuse with the amperage rating designated on
the fuse box lid.
If you do not have a spare fuse, in an emergency you can pull
out the “D−CIG”, “P RR −IG” or “OBD” fuse, which may be
dispensable for normal driving, and use it if its amperage rating
is the same.
If you cannot use one of the same amperage, use one lower
than, but as close to the amperage as possible. If the
amperage is lower than that specified, the fuse might blow out
again but this does not indicate anything wrong. Be sure to get
the correct fuse as soon as possible and return the substitute
to its original clips. It is a good idea to purchase a
set of spare fuses and keep them
in your vehicle for emergencies.
If the new fuse immediately blows out, there is a problem with
the electrical system. Have your Lexus dealer correct it as
soon as possible.
CAUTION
Never use a fuse with a higher amperage rating, or any
other object, in place of a fuse. This may cause
extensive damage and possibly a fire.

CHECKING THE CARTRIDGE TYPEFUSES

Good Blown
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.
CAUTION
Always use a genuine Lexus fuse or equivalent for
replacement. Never install an ordinary wireeven for a
temporary fix. This may cause extensive damage and
possibly a fire.

ELECTRICAL COMPONENTS

NOTICE
Before replacing the fuses, have the cause of electrical
overload determined and repaired by your Lexus dealer.
ADDING WASHER FLUID
64L095b
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.
