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.
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.

CAUTION
Do not disassemble, repair or take apart the low beam
headlight bulbs, connector, power supply circuits
and rotated components. Or you may be injured by
electric shocks. Call your dealer when the headlights
fail to work or have to be replaced or disposed of.
Halogen bulbs have pressurized gas inside and
require special handling. They can burst or shatter if
scratched or dropped. Hold a bulb only by its plastic
or metal case. Do not touch the glass part of a bulb
with bare hands.
NOTICE
Only use a bulb of the listed type.
