DO–IT–YOURSELF SERVICE
PRECAUTIONS
If you perform maintenance yourself, be sure to follow the
correct procedure given in this Section.
You should be aware that improper or incomplete servicing
may result in operating problems.
Performing do–it–yourself maintenance during the warranty
period may affect your warranty coverage. Read the separate
Lexus Warranty statement for details and suggestions.
This Section gives instructions only for those items that are
relatively easy for an owner to perform. As explained in
Section 5, there are still a number of items that must be
performed by a qualified technician with special tools.
For information on tools and parts for do–it–yourself
maintenance, see ”Parts and tools” on page 333.
Utmost care should be taken when working on your vehicle to
prevent accidental injury . Here are a few precautions that you
should be especially careful to observe:
CAUTION
When the engine is running, keep hands, clothing,
and tools away from the moving fan and engine drive
belt. (Removing rings, watches, and ties is
advisable.)
Right after driving, the engine compartment – the
engine, radiator, exhaust manifold and power
steering fluid reservoir, etc. – will be hot. So be
careful not to touch them. Oil and other fluids may
also be hot.
Do not smoke, cause sparks or allow open flames
around fuel or the battery. Their fumes are
flammable.
Do not get under your vehicle with just the body jack
supporting it. Always use automotive jack stands or
other solid supports.
Be sure the ignition is off if you work near the electric
cooling fan o r radiator grille. With the ignition on, the
electric cooling fan may automatically start to run if
the air conditioning is on and/or if the coolant
temperature is high.
Use eye protection whenever you work on or under
your vehicle where you may be exposed to flying or
falling material, fluid spray, etc.
Be extremely cautious when working on the battery.
It contains poisonous and corrosive sulfuric acid.
331
INTRODUCTION
Warning: Battery posts, terminals and related
accessories contain lead and lead compounds,
chemicals known to the State of California to cause
cancer and reproductive harm. Wash hands after
handling.
NOTICE
Remember that battery and ignition cables carry high
currents or voltages. Be careful of accidentally
causing a short circuit.
Before closing the engine hood, check to see that you
have not forgotten any tools, rags, etc.
Do not drive with the air cleaner removed, or
excessive engine wear could result. Also backfiring
could cause a fire in the engine compartment.
Do not overfill automatic transmission fluid, or the
transmission could be damaged.
Be careful not to scratch the glass surface with the
wiper frame.

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 dif ficult 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” on page 388 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.
387
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 th e 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.
388
BODY
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.
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
NOTICE
To prevent damage to the antenna, make sure to remove
it before driving your Lexus 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 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 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.
389
BODY
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 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.
390
BODY
NOTICE
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 de v elop on soiled leather upholstery . Be
especially careful to avoid oil spots. T ry 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.
391
BODY
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.
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.
