terminals with tools.
Do not smoke or light a match near the battery.
The electrolyte contains poisonous and corrosive
sulfuric acid.
Avoid contact with eyes, skin or clothes.
Never inhale or swallow electrolyte.
Wear protective safety glasses when working
near the battery.
Keep children away from the battery.
EMERGENCY MEASURES
If electrolyte gets in your eyes, flush your eyes
with clean water for at least 15 minutes and get
immediate medical attention. If possible,
continue to apply water with a sponge or cloth
while traveling to the medical office.
If electrolyte gets on your skin, thoroughly wash
the contacted area. If you feel a pain or burn, get
medical attention immediately.
If electrolyte gets on your clothes, there is a
possibility of its soaking through to your skin, so
immediately take off the exposed clothing and
follow the procedure above, if necessary.
If you happen to swallow electrolyte, drink a large
quantity of water or milk. Follow with milk of
magnesia, beaten raw egg or vegetable oil. Then
go immediately for emergency help.

cable first and reinstall it last.
Be careful not to cause a short circuit with tools.
Take care no solution gets into the battery when
washing it.
Checking battery fluid
There are 2 types of batteries: maintenance type and
non–maintenance type.
A non–maintenance battery has “MAINTENANCE FREE
BATTERY” on its top. A maintenance type battery does not
have such indication.
Maintenance type battery
Check the fluid condition by the fluid level lines on the side
of the battery. Or if the battery has a hydrometer on its top,
you can also check the hydrometer.
Non–maintenance battery
Check the battery condition by the hydrometer on top of the
battery.
223
ELECTRICAL COMPONENTS
(a) Checking by the flui d level lines (Maintenance type
battery only)
Upper line Lower line
The fluid (electrolyte) level must be between the upper
and lower lines.
When checking the fluid level, look at all six cells, not just one
or two.
If the level is lower than the lower line, add distilled water.
(See “Adding distilled water” on page 225.)
(b) Checking the hydrometer
Check the battery condition by the hydrometer color.

BATTERY RECHARGING
PRECAUTIONS
During recharging, the battery is producing hydrogen
gas.
Therefore, before recharging:
1. Maintenance type batteries – Remove the vent plugs.
2. If recharging with the battery installed on the vehicle, be
sure to disconnect the ground cable.
3. Make sure the power switch on the recharger is of f when
connecting the charger cables to the battery and when
disconnecting them.
CAUTION
!
Always charge the battery in an unconfined area.
Do not charge the battery in a garage or closed
room where there is not sufficient ventilation.
Non–maintenance batteries: Only do a slow
charge (5A or less). Charging at a quicker rate is
dangerous. The battery may explode causing
personal injuries.
Maintenance type batteries: Be sure to remove
the vent plugs before recharging.
NOTICE
Never recharge the battery while the engine is
running. Also, be sure all accessories are turned
off.

ELECTRICAL COMPONENTS
2.Make sure the inoperative component is turned off.
Pull the suspected fuse straight out with the pull–out
tool and check it. If it has blown, push a new fuse into
the clips.
a. Look carefully at the fuse. If the thin wire is broken, the
fuse has blown. If you are not sure or if it is too dark to see,
try replacing the suspected fuse with one of the same value
that you know is good.
b. Only install a fuse with the amperage rating designated
on the fuse box lid.
If you do not have a spare fuse, in an emergency you can pull
out the “RAD NO.1”, “RAD NO.2”“ or “PWR OUTLET” fuse,
which may be dispensable for normal driving, and use it if its
amperage rating is the same.
If you cannot use one of the same amperage, use one lower
than, but as close as possible to, the amperage. If the
amperage is lower than the specified, the fuse might blow
out again but this does not indicate anything wrong. Be sure
to get the correct fuse as soon as possible and return the
substitute to its original clips.
It is a good idea to purchase a set of spare fuses and keep
them in your vehicle for emergencies.
If the new fuse immediately blows out, there is a problem
with the electrical system. Have your Lexus dealer correct
it as soon as possible.
CAUTION
!

PROTECTING YOUR VEHICLE
FROM 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.
BODY
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 difficult 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” 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.
237
BODY
Check the interior of your vehicle. Water and dirt can
accumulate under the floor mats and could cause corrosion.
Occasionally check under the mats to make sure the area is
dry. Be particularly careful when transporting chemicals,
cleansers, fertilizers, salt, etc. These should be transported
in proper containers. If a spill or leak should occur,
immediately clean and dry the area.
Do not park your vehicle in a damp, poorly ventilated
garage. If you wash your vehicle in the garage, or if you drive
it in covered with water or snow, your garage may be so
damp it will cause corrosion. Even if your garage is heated,
a wet vehicle can corrode if the ventilation is poor.
WASHING AND WAXING
Washing your Lexus by hand
Work in the shade and wait until the vehicle body is not
hot to the touch.
1. Rinse off loose dirt with a hose. Remove any mud or
road salt from the underside of the vehicle or in the wheel
wells.
2. Wash with a mild car–wash soap, mixed according to the
manufacturer’s instructions. Use a soft cotton mitt and keep
it wet by dipping it frequently into the wash water. No not rub
hard – let the soap and water remove the dirt.
Aluminum wheels: Use only a mild soap or neutral
detergent.
Urethane bumpers and side moldings: Wash carefully.
Do not scrub with abrasive cleaners. The bumper and side
molding faces are soft.
Road tar: Remove with turpentine or cleaners that are
marked safe for painted surfaces.
NOTICE
Do not use gasoline or strong solvents, which may
be toxic or cause damage.
3. Rinse thoroughly – dried soap can cause streaking. In
hot weather you may need to rinse each section right after
you wash it.
238
4. To prevent water spots, dry the vehicle using a clean soft
cotton towel. Do not rub or press hard – you might scratch
the paint.
Automatic car wash
Your vehicle may be washed in an automatic car wash, but
remember that the paint can be scratched by some type of
brushes, unfiltered washing water, or the washing process
itself. Scratching reduces paint durability and gloss,
especially on darker colors. The manager of the car wash
should be able to advise you whether the process is safe for
the paint on your vehicle.
Waxing your Lexus
Polishing and waxing is recommended to maintain the
original beauty of your Lexus’ finish.
1. Always wash and dry the vehicle before you begin
waxing, even if you are using a combined cleaner and wax.
2. Use a good quality polish and wax. If the finish has
become extremely weathered, use a car–cleaning polish,
followed by a separate wax. Carefully follow the
manufacturer’s instructions and precautions. Be sure to
polish and was the chrome trim as well as the paint.
3. Wax the vehicle again when water does not bead but
remains on the surface in large patches.
BODY
CLEANING THE INTERIOR
CAUTION
!
Do not wash the vehicle floor with water, or allow
water to get onto the floor when cleaning the vehicle
interior or exterior. Water may get into audio
components or other electrical components above
or under the floor carpet (or mat) and cause a
malfunction; and it may cause body corrosion.
Leather Interior
Remove dirt using a soft cloth dampened with 5% solution
of neutral detergent for wool. Then thoroughly wipe off all
traces of detergent with a clean damp cloth.
After cleaning or whenever any part of the leather gets wet,
dry with a soft clean cloth. Allow the leather to dry in a
ventilated shaded area.
NOTICE
If a stain should fail to come out with a neutral
detergent, apply a cleaner that does not contain an
organic solvent.
Never use organic substances such as benzine,
alcohol or gasoline, or alkaline or acid solutions
for cleaning the leather as these could cause
discoloring.
239
BODY
Use of a nylon brush or synthetic fiber cloth, etc.
may scratch the fine grained surface of the leather.
Mildew may develop on soiled leather upholstery.
Be especially careful to avoid oil spots. try to keep
your upholstery always clean.
Long exposure to direct sunlight may cause the
leather surface to harden and shrink. Keep your
vehicle in a shaded area, especially in the summer.
The interior of your vehicle is apt to heat up on hot
summer days, so avoid placing on the upholstery
items made of vinyl or plastic or containing was as
these tend to stick to leather when warm.
Improper cleaning of the leather upholstery could
result in discoloration or staining.
Synthetic Leather Areas (Dash)
The synthetic leather areas may be easily cleaned with
a mild soap or detergent and water.
First vacuum over the upholstery to remove loose dirt. Then,
using a sponge or soft cloth, apply the soap solution to the
synthetic leather. After allowing it to soak in for a few minutes
to loosen the dirt, remove the dirt and wipe off the soap with
a clean damp cloth. If all the dirt does not come off, repeat
the procedure. Commercial foaming–type cleaners are also
available which work well. Follow the manufacturer’s
instructions.
NOTICE
Do not use solvent, thinner, gasoline or window
cleaner on the interior.
240
BODY
Carpets, Windows and Seat Belts
Begin by vacuuming thoroughly to remove as much dirt as
possible. Several types of foam cleaners are available;
some are in aerosol cans and others are powders or liquids
which you mix with water to produce a foam. To shampoo the
carpets, use a sponge or brush to apply the foam. Rub in
overlapping circles. Do not apply water – the best results are
obtained by keeping the carpet as dry as possible. Read the
shampoo instructions and follow them closely.
The seat belts may be cleaned with mild soap and water
or with lukewarm water.
Use a cloth or sponge. As you are cleaning, check the belts
for excessive wear, fraying or cuts.
NOTICE
Use a good foam–type shampoo to clean the
carpets.
Do not use dye or bleach on the belts–it may
weaken them.
The windows may be cleaned with any household
window cleaner.
When cleaning the inside of the rear window, be
careful not to scratch or damage the heater wires.
Air Conditioning Control Panel, Car Audio,
Instrument Panel, Console Panel, and
Switches
Use a soft damp cloth for cleaning.
Soak a clean soft cloth in water or lukewarm water then
lightly wipe off any dirt.
NOTICE
Do not use organic substances (solvents,
kerosene, alcohol, gasoline, etc.) or alkaline or
acidic solutions. These chemicals can cause
discoloring, staining or peeling of the surface.
If you use cleaners or polishing agents, make sure
their ingredients do not include the substances
mentioned above.
If you use a liquid car freshener, do not spill the
liquid onto the vehicle’s interior surfaces. It may
contain the ingredients mentioned above.
Immediately clean any spill using the method
mentioned above.
If you have any questions about the cleaning of your
Lexus, your local Lexus dealer will be pleased to
answer them.

CHECKING BRAKE FLUID
To check the fluid level, simply look at the see–through
reservoir. The level should be between the “MAX” and
“MIN” lines on the tank.
It is normal for the brake fluid level to go down slightly as the
brake pads wear. So be sure to keep the reservoir filled.
If the reservoir needs frequent refilling, it may indicate a
serious mechanical problem.
If the level is low, add FMVSS No. 116 DOT 3 or SAE
J1703 brake fluid to the brake reservoir.
Remove and replace the reservoir cover by hand. Add brake
fluid up to the “MAX” line.
Use only newly opened brake fluid. Once opened, brake fluid
absorbs moisture from the air, and excess moisture can
cause a dangerous loss of braking efficiency.
CAUTION
!
Take care when filling the reservoir because brake
fluid can harm your eyes and damage painted
surfaces. If fluid gets in your eyes, flush your eyes
with clean water.
NOTICE
If you spill some of the fluid, be sure to wash it off
with water to prevent it from damaging the parts or
paintwork.
