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.

1. Turn the ignition switch off and open the fuse box
lid.

lid of the fuse box shows the name of the circuit for each
fuse.

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. 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 ºCIGº, ºRAD NO.1º or ºOBDº 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.

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 wire ± even for
a temporary fix. This may cause extensive damage and
possibly a fire.
NOTICE
Before replacing the fuses, have the cause of
electrical overload determined and repaired by
your Lexus dealer.
