PROTECTING YOUR VEHICLEFROM CORROSION
Proper care of your Lexus can help ensure long±term
corrosion prevention.
The most common causes of corrosion to your vehicle
are:

The accumulation of road salt, dirt and moisture in
hard±to±reach areas under the vehicle.

Chipping of paint or undercoating caused by minor
accidents or by stones and gravel.
The following conditions will cause or accelerate
corrosion of your vehicle, so it is important to keep your
vehicle, particularly the underside, as clean as possible
and to repair any damage to paint or protective coatings
as soon as possible.

The presence of road salt or dust control chemicals, salt in
the air near the sea coast, industrial air pollution.

High humidity, especially at temperatures just above
freezing point.

Certain parts of your vehicle are wet or damp for an
extended period of time, even though other parts of the
vehicle are dry.

Components of the vehicle which are prevented from
quick±drying due to lack of proper ventilation are exposed
to high ambient temperature. To help prevent corrosion on your Lexus, follow these
guidelines:
Keep your vehicle clean by regular washing.
In addition,
observe the following points.

If you drive on salted roads in the winter or if you live near
the ocean, you should hose off the undercarriage at least
once a month to minimize corrosion.

High pressure water or steam is effective for cleaning the
vehicle's underside and wheel housings. Pay particular
attention to these areas as it is difficult to see all the mud and
dirt. It will do more harm than good to simply wet the mud
and debris without removing them. The lower edge of
doors, rocker panels and frame members have drain holes
which should not be allowed to clog with dirt as trapped
water in these areas can cause corrosion.

Wash the underside of the vehicle thoroughly when winter
is over.
See ºWashing and waxingº on page 365 for more tips.
Check the c ondition of your vehicle's paint and trim. If you
find any chips or scratches in the paint, touch them up
immediately to prevent corrosion from starting. If the chips or
scratches have gone through the bare metal, have a qualified
body shop make the repair.

BODY

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 in covered with water or snow, your garage may
be so damp 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 substance

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.

366Plastic 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 t owel. 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 type 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.
Once a month or if the vehicle surface does not repel water
well, apply wax.
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.
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 a leather
product, 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.
