MAINTENANCE REQUIREMENTS
Your Lexus vehicle has been designed to have fewer
maintenance requirements with longer service intervals to
save both your time and money. However, each regular
maintenance as well as day-to-day care is more important
than ever before to ensure smooth, trouble-free, safe, and
economical driving.
It is the owner's responsibility to make sure the specified
maintenance, including general maintenance services, is
performed. Note that both the new vehicle and emission
control system warranties specify that proper maintenance
and care must be performed. See the Owner's Guideº,
Owner's Manual Supplementº or Warranty Bookletº for
complete warranty information.
General maintenance
General maintenance items are those day-to-day care
practices that are important to your vehicle for proper
operation. It is the owner's responsibility to ensure that the
general maintenance items are performed regularly.
These checks or inspections can be done either by yourself or
your Lexus dealer.
Scheduled maintenance
The scheduled maintenance items listed in the Owner's
Manual Supplement/Scheduled Maintenanceº are those
required to be serviced at regular intervals. For details of your maintenance schedule, read the Owner's
Manual Supplement/Scheduled Maintenanceº.
It is recommended that only genuine Lexus parts be used
for maintenance or for the repair of the emission control
system.
The owner may elect to use non-Lexus supplied parts for
replacement purposes without invalidating the emission
control system warranty. However, use of replacement
parts which are not of equivalent quality may impair the
effectiveness of the emission control systems.
You may also elect to have maintenance, replacement, or
repair of the emission control devices and system
performed by any automotive repair establishment or
individual without invalidating this warranty. See
Owner's Guideº, Owner's Manual Supplementº or
Warranty Bookletº for complete warranty information.
Where to go for service?
Lexus technicians are well-trained specialists and
are kept up
to date with the latest service information through technical
bulletins, service tips, and in-dealership training programs.
They are well informed about the operation of all the systems
on your vehicle.
You can be confident that your Lexus dealer's service
department performs the best job to meet the maintenance
requirements of your vehicle Ð reliably and economically.

DO-IT-YOURSELF SERVICEPRECAUTIONS
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 toolsº on page 549.
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 Ð the
engine, radiator, exhaust manifold and power
steering fluid reservoir, etc. Ð will be hot. So be
careful not to touch them. Oil, other fluids and spark
plugs may also be hot.

If the engine is hot, do not remove the radiator cap or
loosen the drain plugs to prevent burning yourself.

Do not leave anything that may burn easily, such as
paper or rags, in the engine compartment.

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.

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.

CHASSIS

Temperature A, B, C Ð The temperature grades are
A (the highest), B, and C, representing the tire's
resistance to the generation of heat and its ability to
dissipate heat when tested under controlled conditions
on a specified indoor laboratory test wheel. Sustained
high temperature can cause the material of the tire
to degenerate and reduce tire life, and excessive
temperature can lead to sudden tire failure. The
grade C corresponds to a level of performance which
all passenger car tires must meet under the Federal
Motor Vehicle Safety Standard No. 109. Grades B
and A represent higher levels of performance on the
laboratory test wheel than the minimum required by
law.
Warning: The temperature grade for this tire
established for a tire that is properly inflated and not
overloaded. Excessive speed, underinflation, or
excessive loading, either separately or in combination,
can cause heat buildup and possible tire failure.

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. 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 634 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
6363. Rinse
thoroughly Ð 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 drivingyour 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.
