CHECKING THE CARTRIDGE TYPEFUSES
Engine compartment
Driver’s side instrument panel 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.

REPLACING LIGHT BULBS
The illustration 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.
CAUTION
 To prevent yourself from burning, do not replace the
light bulbs while they are hot.
 Vehicles with discharge headlight—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.
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 dif ference between the outside and
inside of the lens, just like the windshield fogged 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.
