Good
Blown
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.

Turn the bolt B in either direction using a Phillips−head
screwdriver.
If you do not know or cannot find the original position, or if you
feel that there is a large deviation, take the vehicle to your
Lexus dealer to adjust the headlight aim.
REPLACING LIGHT BULBS
The illustrations on the following pages show the locations of
light bulbs. If it is necessary to replace a bulb, take your vehicle
to your Lexus dealer as soon as possible. Use bulbs with the
bulb numbers and wattage ratings given in the table.
The tail lights, stop lights, high mounted stoplight and rear side
marker light consist of a number of LEDs. If any LED burns out,
we recommend you take your vehicle to your Lexus dealer to
have the light inspected as soon as possible.
CAUTION
To prevent burning yourself, do not replace the light
bulbs while they are hot.
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.
Do not touch the high voltage socket when the head-
lights turn on. 20000 V is momentarily generated and
may cause severe injury by electric shock.
Do not disassemble, repair or take apart the headlight
bulbs, connector, power supply circuits and rotated
components. Or you may be injured by electric
shock. Call your dealer when the headlights fail to
work or have to be replaced or disposed of.

NOTICE
Only use a bulb of the listed type.
The inside of the lens of exterior lights such as headlights may
temporarily fog up when the lens becomes wet in the rain or in
a car wash. This is not a problem because the fogging is
caused by the temperature difference between the outside and
inside of the lens, just like the windshield fogs up in the rain.
However, if there is a large drop of water on the inside of the
lens, or if there is water pooled inside the light, contact your
Lexus dealer.LIGHT LOCATION
