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 temperature.
467
BODY
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 w a te r o r s t ea m i s e ffective 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 ”Washing and waxing” for more tips.
Check the co n d ition 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.
Check the inte r i o r o f 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.
468
BODY
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 stuck of 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 f r o m t h e 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.
469
BODY
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 gasoline or strong solvents, which
may be toxic or cause 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 towel. Do not rub or press hard – you might
scratch the paint.
Automatic 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 does not repel water well,
apply wax.
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.
470
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.
BODY
471
BODY
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 of f 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.
NOTICE
472
Dirt or sand adhered to the leather may damage
the treated surface and cause it to wear earlier.
Remove dirt or sand using a vacuum cleaner.
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.
Synthetic Leather Areas
(Dash and sun visors)
The synthetic leather areas may be easily cleaned
with a mild soap or detergent and water.
First vacuum over the upholstery to remove loose dirt.
Then, using a sponge or soft cloth, apply the soap
solution to the synthetic leather . After allowing it to soak
in for a few minutes to loosen the dirt, remove the dirt and
wipe off the soap with a clean damp cloth. If all the dirt
does not come off, repeat the procedure. Commercial
foaming–type cleaners are also available which work
well. Follow the manufacturer’s instructions.
NOTICE
Do not use solvent, thinner, gasoline or window
cleaner on the interior.
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. T o shampoo the carpets, use a sponge or brush
to apply the foam. Rub in overlapping circles. Do not
BODY
473
BODY
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.
Use a cloth or sponge. As you are cleaning, check the
belts for excessive wear, fraying or cuts.
NOTICE
Use a good foam–type shampoo to clean the
carpets.
Do not use dye or bleach on the belts – it may
weaken them.
Do not use the belts until they become dry.
The windows may be cleaned with any
household window cleaner.
When cleaning the inside of the rear window, be
careful not to scratch or damage the heater
wires.
Air Conditioning Control Panel, Car
Audio, Instrument Panel, Console Panel,
and Switches
Use a soft damp cloth for cleaning.
Soak a clean soft cloth in water or lukewarm water then
lightly wipe off any dirt.
NOTICE
Do not use organic substances (solvents,
kerosene, alcohol, gasoline, etc.) or alkaline or
acidic solutions. These chemicals can cause
discoloring, staining or 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.
