PROTECTING YOUR VEHICLE
FROM 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. 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 Washing and waxingº on page 581 for more tips.
Check the condition 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
581 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.
Use mud shields on your wheels. If you drive on salted or
gravel roads, mud shields help protect your vehicle. Full-size
shields, which come as near to the ground as possible, are the
best. We recommend that the fittings and the area where the
shields are installed be treated to resist corrosion. Your Lexus
dealer will be happy to assist in supplying and installing the
shields if they are recommended for your 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
Ð let the soap and water remove the dirt.

BODY
582Fuel 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
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 or
cause damage.

BODY
583 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 Ð you might scratch the
paint.
Automatic car wash
NOTICE
Vehicles with Lexus link system: To prevent damage to
the antenna, make sure it is removed before driving
your vehicle through an 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 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 INTERIORCAUTION
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
Remove dirt using a soft cloth dampened with 5% solution of
neutral detergent for wool. Then thoroughly wipe off all traces
of detergent with a clean damp cloth.
After cleaning or whenever any part of the leather gets wet, dry
with a soft clean cloth. Allow the leather to dry in a ventilated
shaded area.

BODY
585
NOTICE

If a stain should fail to come out with a neutral
detergent, apply a cleaner that does not contain an
organic solvent.

Never use organic substances such as benzine,
alcohol or gasoline, or alkaline or acid solutions for
cleaning the leather as these could cause
discoloring.

Use of a nylon brush or synthetic fiber cloth, etc. may
scratch the fine grained surface of the leather.

Mildew may develop on soiled leather upholstery. Be
especially careful to avoid oil spots. Try to keep your
upholstery always clean.

Long exposure to direct sunlight may cause the
leather surface to harden and shrink. Keep your
vehicle in a shaded area, especially in the summer.

The interior of your vehicle is apt to heat up on hot
summer days, so avoid placing on the upholstery
items made of vinyl or plastic or containing wax as
these tend to stick to leather when warm.

Improper cleaning of the leather upholstery could
result in discoloration or staining.
