ENGINE
369 More oil is consumed under driving conditions such as high
speeds and frequent acceleration and deceleration.
A new engine consumes more oil, since its pistons, piston rings
and cylinder walls have not become conditioned.
Oil consumption: Max. 1.0 L per 1000 km (1.1 qt./600 miles,
0.9 lmp. qt./600 miles)
When judging the amount of oil consumption, keep in
mind that the oil may have become diluted, making it
difficult to judge the true level accurately.
For example, if a vehicle is used for repeated short trips and
consumes a normal amount of oil, the dipstick may not show
any drop in the oil level at all, even after 1000 km (600 miles)
or more. This is because the oil is gradually becoming diluted
with fuel or moisture, making it appear that the oil level has not
changed.
The diluting ingredients evaporate out when the vehicle is then
driven at high speeds, as on an expressway, making it appear
that oil is excessively consumed after driving at high speeds.
Importance of engine oil level check
One of the most important points in proper vehicle
maintenance is to keep the engine oil at the optimum level so
that oil function will not be impaired. Therefore, it is essential
that the oil level be checked regularly. Lexus recommends that
the oil level be checked every time you refuel the vehicle.
NOTICE
Failure to check the oil level regularly could lead to
serious engine trouble due to insufficient oil.
For detailed information on oil level check, see Checking the
engine oil levelº on page 370.USED ENGINE OIL

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.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 443 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.

SwitchesUse 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.
