1. Turn the ignition switch off and open the fuse box lid.
Determine which fuse may he causing the problem. The lid of
the fuse box shows the name of the circuit for each fuse.
2. Make sure the inoperative component is turned off.
Pull the suspected fuse straight out with the pull-out tool
and check it. If it has blown, push a new fuse into the clips.

a. Look carefully at the fuse. If the thin wire is broken, the fuse
has blown. If you are not sure or if it is too dark to see, try
replacing the suspected fuse with one of the same value that
you know is good.

198b. Install only a fuse with the amperage rating designated on
the fuse box lid.
If you do not have a spare fuse, in an emergency you can pull
out the “CIG / RADIO”, “RADIO”, “DOME” or “MIR-HTR” fuse,
which may be dispensable for normal driving, and use it if its
amperage rating is the same.
If you cannot use one of the same amperage, use one lower
than, but as close as possible to, the amperage. If the
amperage is lower than that specified, the fuse might blow out
again but this does not indicate anything wrong. Be sure to get
the correct fuse as soon as possible and return the substitute
to its original clips.
It is a good idea to purchase a set of spare fuses and keep them
in your vehicle for emergencies.
If the new fuse immediately blows out, there is a problem with
the electrical system. Have your Lexus dealer correct it as
soon as possible.
CAUTION:
Never use a fuse with a higher amperage rating, or any
other object, in place of a fuse. This may cause extensive
damage and possibly a fire.
CHECKING THE CARTRIDGE TYPE

Engine compartment
Passenger’s side kick 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.

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
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
Beam angle gauge
(horizontal movement)
Beam angle gauge
(vertical 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.
Acceptable range
Bubble
Beam angle gauge
(vertical movement)
To check the headlight aim, check the vertical and
horizontal gauges.
1. Look at the beam angle gauge (vertical movement). 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.

Mark
Beam angle gauge
(horizontal movement)
2. Look at the beam angle gauge (horizontal movement). The
blue mark 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.
