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

Engine compartment

Driver's side instrument panel
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.

ELECTRICAL COMPONENTS
231
CHECKING THE HEADLIGHT AIM


Beam angle gauge (horizontal movement)
Beam angle gauge (vertical movement)
Before checking the headlight aim:
1. Be sure that the body around the headlights is not
deformed.
2. Park the vehicle on a level spot.
3. The driver gets into the driver's seat so that the vehicle
has its normal load (with the tank full).
4. Bounce the vehicle several times.


Bubble Acceptable range
Vertical movement gauge: The bubble of the gauge should
not deviate from the center of the gauge by more than two
marks to either side of the gauge.

ELECTRICAL COMPONENTS
232


Arrow head Acceptable range
Horizontal movement gauge: The arrow head should not
deviate by more than one mark to either side of the gauge.
If the error is over the value specified above, take the vehicle
to your Lexus dealer to adjust the headlight aim.
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!
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.
