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 608 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.

peeling of the surface.

If you use cleaners or polishing agents, make sure
their ingredients do not include the substances
mentioned above.

If you use a liquid car freshener, do not spill the liquid
onto the vehicle's interior surfaces. It may contain
the ingredients mentioned above. Immediately clean
any spill using the method mentioned above.
If you have any questions about the cleaning of your
Lexus, your local Lexus dealer will be pleased to answer
them.RAIN CLEARING MIRRORS
The rear view mirrors have been coated to produce a rain
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.
