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.
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 any
other object, in place of a fuse. This may cause extensive
damage and possibly a fire.
CHECKING THE CARTRIDGE TYPE
FUSES
Engine compartment
Passenger’s side kick panel
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.
