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.

ELECTRICAL COMPONENTS

NOTICE
Before replacing the fuses, have the cause of electrical
overload determined and repaired by your Lexus dealer.
ADDING WASHER FLUID
If the washer tank becomes nearly empty, add washer
fluid.
You may use plain water as washer fluid. However, in cold
areas where temperatures range below the freezing point, use
washer fluid containing antifreeze. This product is available at
your Lexus dealer and most auto parts stores. Follow the
manufacturer’s directions for how much to mix with water.
NOTICE
 Do not use engine antifreeze or any other substitute
because it may damage your vehicle’s paint.
 Do not fill washer fluid over the “NORMAL” level.

Before checking the headlight aim:
1. Be sure that the body around the headlight is not deformed.
2. Park the vehicle on a level spot.
3. The driver gets into the driver’s seat and puts the vehicle in
a state readying for a driving (with a full tank).
4. Bounce the vehicle several times.
Adjusting the vertical aiming
1. Turn the vertical movement adjusting bolt 1 in either
direction using a Phillips −head screwdriver. At this time, keep
the turning direction and number of turns in mind.

2. Turn the vertical movement adjusting bolt 2 the same
number of turns and in the same direction at step 1 using a
Phillips−head screwdriver.
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 burning yourself, 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. LIGHT LOCATION

PROTECTING YOUR VEHICLEFROM CORROSION
Proper care of your Lexus can help ensure long −term
corrosion prevention.
The most common causes of corrosion to your vehicle
are:
 The accumulation of road salt, dirt and moisture in
hard−to−reach areas under the vehicle.
 Chipping of paint or undercoating caused by minor
accidents or by stones and gravel.
The following conditions will cause or accelerate
corrosion of your vehicle, so it is important to keep your
vehicle, particularly the underside, as clean as possible
and to repair any damage to paint or protective coatings
as soon as possible.
 The presence of road salt or dust control chemicals, salt in
the air near the sea coast, industrial air pollution.
 High humidity, especially at temperatures just above
freezing point.
 Certain parts of your vehicle are wet or damp for an
extended period of time, even though other parts of the
vehicle are dry.
 Components of the vehicle which are prevented from
quick−drying due to lack of proper ventilation are exposed
to high temperature. To help prevent corrosion on your Lexus, follow these
guidelines:
Keep your vehicle clean by regular washing.
In addition,
observe the following points.
 If you drive on salted roads in the winter or if you live near
the ocean, you should hose off the undercarriage at least
once a month to minimize corrosion.
 High pressure water or steam is effective for cleaning the
vehicle’s underside and wheel housings. Pay particular
attention to these areas as it is dif ficult to see all the mud and
dirt. It will do more harm than good to simply wet the mud
and debris without removing them. The lower edge of
doors, rocker panels and frame members have drain holes
which should not be allowed to clog with dirt as trapped
water in these areas can cause corrosion.
 Wash the underside of the vehicle thoroughly when winter
is over.
See “Washing and waxing” on page 357 for more tips.
Check the condition of your vehicle’s paint and trim. If you
find any chips or scratches in the paint, touch them up
immediately to prevent corrosion from starting. If the chips or
scratches have gone through the bare metal, have a qualified
body shop make the repair.
