1. Turn the ignition switch off and open the fuse box lid.
Determine which fuse may be causing the problem. The 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.
NOTICE
Before replacing the fuses, have the cause of electrical
overload determined and repaired by your Lexus dealer.
