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 immediately and get immediate medical
attention. If possible, continue to apply water with a
sponge or cloth while traveling to the medical office.

ELECTRICAL COMPONENTS
604Check the battery condition by the indicator color.
Type A —
1BLUE — Good condition
2WHITE — Charging necessary. Have the battery
checked by your Lexus dealer.
3RED — Have the battery checked by your Lexus dealer.
Type B —
1GREEN — Good condition
2DARK — Charging necessary. Have the battery checked
by your Lexus dealer.
3CLEAR or LIGHT YELLOW — Have the battery checked
by your Lexus dealer.
NOTICE
Do not refill the battery with water.
BATTERY RECHARGING PRECAUTIONS
During recharging, the battery is producing hydrogen
gas.
Therefore, before recharging:
1. If recharging with the battery installed on the vehicle, be
sure to disconnect the ground cable.
2. Make sure the power switch on the recharger is off 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.
 Only do a slow charge (5 A or less). Charging at a
quicker rate is dangerous. The battery may explode
causing personal injuries.
NOTICE
Never recharge the battery while the engine is running.
Also, be sure all accessories are turned off.

ELECTRICAL COMPONENTS

1Type A2Type B3Good4Blown
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.

ELECTRICAL COMPONENTS
609
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.
CHECKING THE HEADLIGHT AIM
(vehicles with discharge headlight)
1Vertical movement adjusting screw
2Vertical movement adjusting bolt
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.

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.
The stop lights consist of a number of LEDs. If two or more
LEDs burn out, your vehicle may not conform to local laws
(SAE). If this occurs, take your vehicle to your Lexus dealer to
have the light replaced.
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.
Vehicles with power back door system —
 When replacing the rear light bulbs, turn off the
power back door system.
Vehicles with discharge headlights —
Do not touch the high voltage socket when the low
beam headlight turns on. 20000 V is momentarily
generated and may cause severe injury by electric
shock.
 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.
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 difference 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.

BODY
620Fuel
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.
Electronically modulated air suspension: Do not spray a jet
of high−pressure water at the air suspension unit, especially
the air spring, at an extremely close range. This may damage
the air suspension.
Plastic wheel ornaments: The plastic wheel ornaments are
damaged easily by organic substances. If any organic
substance splash an ornament, be sure to wash them off 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
removed before driving your vehicle through an
automatic car wash.
 When your vehicle goes through an automatic car
wash, make sure the power back door system is off.
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.

BODY
621
Waxing your Lexus
Polishing and waxing is recommended to maintain the
original beauty of your Lexus’ finish.
Apply may 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 that the nozzles do
not become blocked when wa xing. 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 system
components or other electrical components above or
under the floor carpet (or mat) and cause a
malfunction; and it may cause body corrosion.
