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.

261
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.
CHECKING THE HEADLIGHT AIM
(Vehicles with discharge headlight only)
64L0732
1
Adjusting bolt (vertical movement)
2
Beam angle gauge and adjusting bolt
(horizontal movement)
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.

3. Turn the horizontal movement adjusting bolt the same number of
turns and in the same direction at step 2.
4. Push the lock release of the horizontal movement adjusting bolt
in the opposite direction as you did at step 1 to lock the adjusting bolt.
Adjusting the horizontal aiming
64L021-1

Mark 2
Acceptable range
Horizontal movement gauge: The mark should not deviate by
more than 2 marks 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
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.
