" Good
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.
