CHECKING BATTERY CONDITION
Precautions
CAUTION
BATTERY PRECAUTIONS
The battery produces flammable and explosive hydrogen gas.
Do not cause a spark by contacting the battery 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.

CHECKING THE CARTRIDGE TYPE
FUSES
64L016-3
1
Good 2
Melted
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 wireeven for a
temporary fix. This may cause extensive damage and possibly
a fire.

ADDING WASHER FLUID
64L017
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.

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
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.

CLEANING THE INTERIOR
CAUTION
Be careful not to splash water or spill liquid on the floor.
This may prevent the side airbags from activating
correctly, resulting in serious injury.
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
The selected leather is used in your Lexus. Due to a leather product,
some parts of leather may be rough, uneven or scratched originally.
To keep good appearance, we recommend you to clean it
periodically twice a year.
Remove dirt on the leather in the following ways:
1. Wipe it off lightly using a soft cloth (e.g. gauze) dampened with
5% solution of neutral detergent for wool.
2. Wring water from a clean cloth and thoroughly wipe off all traces
of detergent with it.3. Wipe off the surface of the leather with a dry soft cloth. Allow
the leather to dry in a ventilated shaded area. Excess of wet may
cause the hardening or shrinking of the leather.
NOTICE
Dirt or sand adhered to the leather may damage the treated
surface and cause it to wear earlier. Remove dirt or sand
using a vacuum cleaner.
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.
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 wax as these tend to stick to leather
when warm.
Improper cleaning of the leather upholstery could result in
discoloration or staining.
