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.
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.

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
G64020

1
Beam angle gauge
(horizontal movement for high beam)
2
Beam angle gauge
(vertical movement for high beam)
3
Beam angle gauge
(vertical movement for low beam)
4
Beam angle gauge
(horizontal movement for low beam)
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.

Bubble 2
Acceptable range
Vertical movement gauge: The bubble of the gauge should
not deviate from the center of the gauge by more than 2 marks
to either side of the gauge.
If the bubble is out of the acceptable range of the beam angle
gauge, adjust it using bolt A and B.

1. Turn the bolt A in either direction using a Phillips−head
screwdriver. At this time, keep the turning direction and
number of turns in mind.
G64024
2. Turn the bolt B the same number of turns and in the same
direction as step 1 using a Phillips−head screwdriver.
If you do not know or cannot find the original position, or if you
feel that there is a large deviation, take the vehicle to your
Lexus dealer to adjust the headlight aim.
After adjusting the headlight in the vertical direction, check that
the light has been shifted from the adjusted position in the
horizontal direction.
