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.

ELECTRICAL COMPONENTS

NOTICE
Make sure the engine and all accessories are turned
off before performing maintenance.
 When checking the battery, remove the ground 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.
If the battery terminal is disconnected or the battery is run
down...
 The variable gear ratio steering system is reset temporarily
and “VGRS” warning light flashes after you reconnect the
battery terminal. In this case, you should turn off the light
and return the system to normal. To return the system to
normal, see “Variable gear ratio steering system” on page
293.
 The moon roof may not operate automatically and the jam
protection function will not operate correctly after you
reconnect, replace or recharge the battery with the moon
roof slide −opened or tilted up. In any of these cases, you
should return the moon roof to normal. To return the moon
roof to normal, see “Moon roof” on page 95.
Checking battery condition
(a) Checking by fluid level lines
64X005c
 1 Upper line 2Lower 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, have the battery
checked by your Lexus dealer.

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.
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 wire even for
a temporary fix. This may cause extensive damage and
possibly a fire.

ADDING WASHER FLUID
64X603a
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.
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 and stop lights 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.
If two or more LEDs in a stop light burn out, your vehicle may
not conform to local laws(SAE).
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.
NOTICE
Only use a bulb of the listed type.

ELECTRICAL COMPONENTS
459
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 pr oblem because the fogging is
caused by the temperature dif ference 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

BODY
4661. Rinse off loose dirt with a hose. Remove any mud or road
salt from the underside of the vehicle or 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. Do not rub
hard − let the soap and water remove the dirt.
Fuel filler door: Do not apply water (high −pressure car wash,
for example) at or near the fuel tank inlet with the fuel filler door
opened. If the water enters the air vent, you may experience
trouble with refueling or rough engine idling.
Plastic wheel ornaments: The plastic wheel ornaments are
damaged easily by organic substances. If any organic
substances splash an ornament, be sure to wash them of f with
water and check if the ornament is damaged.
Aluminum wheels: Use only a mild soap or neutral detergent.
Plastic bumpers and side moldings: Wash carefully. Do not
scrub with abrasive cleaners. The bumper and side molding
faces are soft.
Exterior lights: Wash carefully. Do not use organic
substances or scrub them with a hard brush. This may
damage the surfaces of the lights.
Road tar: Remove with turpentine or cleaners that are marked
safe for painted surfaces.
3. Rinse thoroughly − dried soap can cause streaking. In hot
weather you may need to rinse each section right after you
wash it. 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.
NOTICE
 Do not use organic substances (gasoline, kerosene,
benzine or strong solvents), which may be toxic or
cause damage.
 Do not scrub any part of the vehicle with a hard brush,
which may cause damage.
Automatic car wash
NOTICE
To prevent damage to the antenna, make sure it is
retracted before driving your vehicle through an
automatic car wash.
Your vehicle may be washed in an automatic car wash, but
remember that the paint can be scratched by some types 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.
Apply wax once a month or if the vehicle surface does not repel
water well.
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 wax 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.
Windshield washer nozzles: Make sure the washer nozzles
do not become blocked. If a nozzle becomes blocked, contact
your Lexus dealer to have the vehicle serviced.
NOTICE
If a nozzle becomes blocked, do not try to clear it with
a pin or other object. The nozzle will be damaged.
Exterior lights: Do not apply wax on the surfaces of the lights.
Wax may cause damage to the lenses. If you accidentally put
wax on the light surfaces, wipe or wash it off.
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.
Leathertrimmed 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.
