1. Remove the vent plugs.
2. Add distilled water to cells needing fluid.
If the side of your battery is covered, check the water
level by looking down directly above the cell as
illustrated above.
3. Retighten the vent plugs securely.
NOTICE
Do not overfill the cells. Excess electrolyte
could squirt out of the battery during heavycharging, 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. Maintenance type batteries ± Remove the vent plugs.
2. If recharging with the battery installed on the vehicle,
be sure to disconnect the ground cable.
3. 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.
 Non±maintenance batteries: Only do a slow charge
(5 A or less). Charging at a quicker rate is dangerous.
The battery may explode causing personal injuries.
Maintenance type batteries: Be sure to remove the
vent plugs before recharging.

1. Turn the ignition switch off and remove the
auxiliary box.
Determine which fuse may be causing the problem. The
auxiliary 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
pull±out tool and check it. If it has blown, push a new
fuse into the clips.

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 ºRAD NO.1º, ºRAD NO.2º or ºPWR
OUTLETº 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.

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.
