REPLACING LIGHT BULBS
The illustrations 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 tail lights, stop lights, high mounted stoplight and rear side
marker light consist of a number of LEDs. If any LED burns out,
we recommend you take your vehicle to your Lexus dealer to
have the light inspected as soon as possible.
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.
 Do not touch the high voltage socket when the head-
lights turn on. 20000 V is momentarily generated and
may cause severe injury by electric shock.
 Do not disassemble, repair or take apart the headlight
bulbs, connector, power supply circuits and rotated
components. Or you may be injured by electric
shock. 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 pr oblem because the fogging is
caused by the temperature dif ference 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. LIGHT LOCATION

Fuel
filler door: Do not apply water (high −pressure car wash,
for example) at or near the fuel tank inlet with the fuel filler door
opened. If the water enters the air vent, you may experience
trouble with refueling or rough engine idling.
Plastic wheel ornaments: The plastic wheel ornaments are
damaged easily by organic substances. If any organic
substances splash an ornament, be sure to wash them of f with
water and check if the ornament is damaged.
Aluminum wheels: Use only a mild soap or neutral detergent.
Plastic bumpers and side moldings: Wash carefully. Do not
scrub with abrasive cleaners. The bumper and side molding
faces are soft.
Exterior lights: Wash carefully. Do not use organic
substances or scrub them with a hard brush. This may
damage the surfaces of the lights.
Road tar: Remove with turpentine or cleaners that are marked
safe for painted surfaces.
3. Rinse thoroughly − dried soap can cause streaking. In hot
weather you may need to rinse each section right after you
wash it.
4. To prevent water spots, dry the vehicle using a clean soft
cotton towel. Do not rub or press hard − you might scratch the
paint.
NOTICE
 Do not use organic substances (gasoline, kerosene,
benzine or strong solvents), which may be toxic or
cause damage.
 Do not scrub any part of the vehicle with a hard brush,
which may cause damage.
Automatic car wash
Your vehicle may be washed in an automatic car wash, but
remember that the paint can be scratched by some types of
brushes, unfiltered washing water, or the washing process
itself. Scratching reduces paint durability and gloss, especially
on darker colors. The manager of the car wash should be able
to advise you whether the process is safe for the paint on your
vehicle.
Waxing your Lexus
Polishing and waxing is recommended to maintain the
original beauty of your Lexus’ finish.
Apply wax once a month or if the vehicle surface does not repel
water well.
1. Always wash and dry the vehicle surface before you begin
waxing, even if you are using a combined cleaner and wax.
2. Use a good quality polish and wax. If the finish has become
extremely weathered, use a car−cleaning polish, followed by
a separate wax. Carefully follow the manufacturer’s
instructions and precautions. Be sure to polish and wax the
chrome trim as well as the paint.
