Type B —
1GREEN — Good condition
2DARK — Charging necessary. Have the battery checked

NOTICE
Do not refill the battery with water.
BATTERY RECHARGING PRECAUTIONS
During recharging, the battery is producing hydrogen
gas.
Therefore, before recharging:
1. If recharging with the battery installed on the vehicle, be
sure to disconnect the ground cable.
2. Make sure the power switch on the recharger is off when
connecting the charger cables to the battery and when
disconnecting them.
CAUTION
Always charge the battery in an unconfined area. Do
not charge the battery in a garage or closed room
where there is not sufficient ventilation.
 Only do a slow charge (5 A or less). Charging at a
quicker rate is dangerous. The battery may explode
causing personal injuries.
NOTICE
Never recharge the battery while the engine is running.
Also, be sure all accessories are turned off.

CHECKING AND REPLACING THEBLADE TYPE FUSES
Engine compartment 1 Pullout tool 2 Spare fuses
Driver’s side instrument panel
1. Turn the ignition switch off and remove the fuse box lid.
Determine which fuse may be causing the problem. The lid of
the fuse box shows the name of the circuit for each fuse.

606
2. Make sure the inoperative component is turned off. Pull
the suspected fuse straight out with the pullout tool and
check it. If it has blown, push a new fuse into the clips. Good Blown
1. 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.
2. Only install 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 “RADIO NO.1”, “RADIO NO.2” or “PWR OUTLET
NO.1” 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 to the amperage as possible. 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.

ELECTRICAL COMPONENTS
607
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.
You should normalize the power back door, power windows
and moon roof if they do not work or the jam protection function
does not operate correctly after replacing blown fuses. In
these cases, you should do the each instructions referring on
the following pages.

Power back door (See page 42.)
 Power windows (See page 65.)
 Moon roof (See page 131 or 134.)
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

1Type A2Type B3Good4Blown
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
(vehicles with discharge headlight)
1Vertical movement adjusting screw
2Vertical movement adjusting bolt
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.

ELECTRICAL COMPONENTS
610
Adjusting the vertical aiming
1. Turn the Phillips−head screwdriver to either direction in
order to turn the vertical movement adjusting screw ( 1
).
Remember the number of times you turn the screwdriver and
the turning direction.
2. When turning the vertical movement adjusting bolt ( 2
),
turn the Phillips−head screwdriver to the same direction as
step 1. To calculate the correct number of turns, multiply the
number of times you turned the screwdriver in step 1 by 1.25.
Turn the screwdriver by this amount.

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.
The stop lights consist of a number of LEDs. If two or more
LEDs burn out, your vehicle may not conform to local laws
(SAE). If this occurs, take your vehicle to your Lexus dealer to
have the light replaced.
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.
Vehicles with power back door system —
 When replacing the rear light bulbs, turn off the
power back door system.
Vehicles with discharge headlights —
Do not touch the high voltage socket when the low
beam headlight turns on. 20000 V is momentarily
generated and may cause severe injury by electric
shock.
 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.
NOTICE
Only use a bulb of the listed type.
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 problem because the fogging is
caused by the temperature difference 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.
