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

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
