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.

199 If there is an overload in the circuits from the battery, the fuses
are designed to melt 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.
REPLACING THE WINDSHIELD
WIPER BLADES
When the wipers no longer clean adequately, the wiper
blades may be worn or cracked, requiring replacement.
Before replacement
Make sure whether the wiper blades are at the rest
position or at the retracted position.
If at the rest position---
Swing the wiper arm away from the windshield until it stands
up.
