Check the interior of your vehicle. Water and dirt can
accumulate under the floor mats and could cause corrosion.
Occasionally check under the mats to make sure the area is
dry. Be particularly careful when transporting chemicals,
cleansers,
fertilizers, salt, etc. These should be transported in
proper containers. If a spill or leak should occur, immediately
clean and dry the area.
Keep your vehicle in a well ventilated garage or a roofed
place. Do not park your vehicle in a damp, poorly
ventilated garage. If you wash your vehicle in the garage, or
if you drive it covered with water or snow, your garage may be
so damp and it will cause corrosion. Even if your garage is
heated, a wet vehicle can corrode if the ventilation is poor.
WASHING AND WAXING
Washing your Lexus
Keep your vehicle clean by regular washing.
The following cases may cause weakness to the paint or
corrosion to the body and parts. Wash your vehicle as soon
as possible.

When driving in a coastal area

When driving on a road sprinkled with antifreeze

When having coal tar, tree sap, bird droppings and carcass
of an insect

When driving in the areas where there is a lot of smoke,
soot, dust, iron dust and chemical substances

When the vehicle becomes remarkably dirty with dust and
mud
Hand-washing your Lexus
Work in the shade and wait until the vehicle body is not hot
to the touch.
1. Rinse off loose dirt with a hose. Remove any mud or road
salt from the underside of the vehicle or in the wheel wells.
2. Wash with a mild car-wash soap, mixed according to the
manufacturer's instructions. Use a soft cotton mitt and keep
it wet by dipping it frequently into the wash water. Do not rub
hard - let the soap and water remove the dirt.

396Plastic wheel ornaments:
The plastic wheel ornaments are
damaged easily by organic substances. If any organic
substance splashes an ornament, be sure to wash it off with
water and check if the ornament is damaged.
CAUTION
Do not attach the heavily damaged plastic wheel
ornament. It may fly off the wheel and cause accidents
while the vehicle is moving.
Aluminum wheels: Use only a mild soap or neutral detergent.
Urethane bumpers and side moldings: Wash carefully. Do
not scrub with abrasive cleaners. The bumper and side
molding faces are soft.
Road tar: Remove with turpentine or cleaners that are marked
safe for painted surfaces.
NOTICE
Do not use organic substances (gasoline, kerosene,
benzine or strong solvents), which may be toxic orcause damage.
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 tow el. Do not rub or press hard - you might scratch the
paint.
Automatic car wash
NOTICE
To prevent damage to the antenna, make sure it is removed before driving your vehicle through anautomatic 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.
3. Wax the vehicle again when water does not bead but
remains on the surface in large patches.
Windshield washer nozzles: Make sure that the nozzles do
not become blocked when waxing. If a nozzle becomes
blocked, contact your Lexus dealer to have the vehicle
serviced.
NOTICE
If a nozzle becomes blocked, do not try to clear it with a pin or other object. The nozzle will be damaged.
CLEANING THE INTERIOR
CAUTION

Be careful not to splash water or spill liquid on the
floor. This may prevent the side airbags from
activating correctly, resulting in serious injury.

Do not wash the vehicle floor with water, or allow
water to get onto the floor when cleaning the vehicle
interior or exterior. Water may get into audio
components or other electrical components above or
under the floor carpet (or mat) and cause a
malfunction; and it may cause body corrosion.
Leather Interior
The selected leather is used in your Lexus. Due to
characteristics of leather products, some parts of leather may
be rough, uneven or scratched originally.
To keep good appearance, we recommend you to clean it
periodically twice a year.
Remove dirt on the leather in the following ways:
1. Wipe it off lightly using a soft cloth (e.g. gauze) dampened
with 5% solution of neutral detergent for wool.
2. Wring water from a clean cloth and thoroughly wipe off all
traces of detergent with it.
3. Wipe off the surface of the leather with a dry soft cloth. Allow
the leather to dry in a ventilated shaded area. Excess of wet
may cause the hardening or shrinking of the leather.

Carpets, Windows and Seat Belts
Begin by vacuuming thoroughly to remove as much dirt as
possible. Several types of foam cleaners are available; some
are in aerosol cans and others are powders or liquids which
you mix with water to produce a foam. To shampoo the
carpets, use a sponge or brush to apply the foam. Rub in
overlapping circles. Do not apply water - the best results are
obtained by keeping the carpet as dry as possible. Read the
shampoo instructions and follow them closely.
The seat belts may be cleaned with mild soap and water
or with lukewarm water.

RAIN CLEARING MIRRORS
The rear view mirrors have been coated to produce a ºrain
clearingº effect. This coating causes the raindrops to
spread, clearing the driver's rear view when it rains.
It is sufficient to wash the mirrors with water for day to day care.
The rain clearing effect is reduced in drizzle and light rain.
In the following cases, the rain clearing effect will be reduced
temporarily, but will gradually recover.

After wiping dirt off the mirrors

When the mirrors fog up

After waxing your vehicle in an automatic car wash

After your vehicle has been parked for a long period in
underground parking lots, etc. where there is no direct sunlight.
If you would like to restore the rain clearing effect to its normal
level immediately in the above cases, wash the mirrors with
neutral detergent, then rinse thoroughly.
NOTICE
To maintain the rain clearing ability, and prevent the mirrors from being scratched, observe the followingprecautions.

Do not use any glass cleaners that containcompounds.

If ice should jam the mirror, do not scrape the mirror.Use a spray deicer to free the mirror.

Wash off any wax stuck to the mirrors with neutraldetergent and rinse thoroughly as any wax on thesurface of the mirrors can cause the rain clearingeffect to be lost.

Do not use any water repellents as they can destroythe rain clearing effect. If any repellent gets stuck onthe surface of the mirrors, wash it off with neutraldetergent, then rinse thoroughly.
