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.
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:

Be sure the engine and all accessories are off before
performing maintenance.

Remove the ground cable first and reinstall last.

Be careful not to cause a short circuit with tools.
2. Check the indicator as shown.
RED − Add distilled water
WHITE − Charging necessary.
BLUE − Good condition.
If the indicator is red, check the electrolyte level as shown.
a. When checking the electrolyte level, look at all six cells, not
just one or two.
b. Remove the vent plugs and replenish the battery with
distilled water.
c. After replenishing, be sure to securely retighten the vent
plugs.

NOTICE:

Do not overfill the battery, or the electrolyte may
squirt out of the battery during periods of 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. Remove the vent plugs.
2. If recharging with the battery installed on the vehicle, be
sure to disconnect the ground cable.
3. Be 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 insufficient ventilation.
NOTICE:
Never recharge the battery while the engine is running.
Also, be sure all accessories are turned off.
CHECKING AND REPLACING
THE BLADE TYPE FUSES

198b. Install only 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 “CIG/RADIO”, “RADIO”, “DOME” or “MIR-HTR” 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 as possible to, the amperage. 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 another
object, in place of a fuse. It may cause extensive damage
and possibly cause a fire.
CHECKING THE CARTRIDGE
TYPE FUSES
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
melted, they must be replaced.

ADDING WASHER FLUID
If any washer does not work, the washer tank may be
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 on how much to mix with water.
NOTICE:
Do not use engine antifreeze or any other substitute
because it may damage your vehicle’s paint.
CHECKING THE HEADLIGHT AIM
Before checking the headlight aim:
1. Be sure that the body around the headlight is not deformed.
2. Park the vehicle on a level spot.
3. The driver gets into the driver’s seat and puts the vehicle in
a state readying for a driving (with a full tank).
4. Bounce the vehicle several times.
