2001 Lexus IS300 oil

ENGINE
239
The amount of engine oil consumed depends on the
viscosity of the oil, the quality of the oil and the way the
vehicle is driven.
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.
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 ºChecking the
engine oil levelº on page 240.

USED ENGINE OIL
CAUTION
Used engine oil contains potentially harmful
contaminants which may cause skin disorders such
as inflammation or skin cancer, so care should be
taken to avoid prolonged and repeated contact with
it. To remove used engine oil from your skin, wash
thoroughly with soap and water.
 Do not leave used oil within the reach of children.
 Dispose of used oil and used oil filters only in a safe
and acceptable manner. Do not dispose of used oil
and used oil filters in household trash, in sewers or
onto the ground. Call your Lexus dealer or a service
station for information concerning recycling or
disposal.
CHECKING THE ENGINE OIL LEVEL
SV62004
With the engine at operating temperature and turned off,
check the oil level on the dipstick.
1. To get a true reading, the vehicle should be on a level spot.
After turning off the engine, wait a few minutes for the oil to
drain back into the bottom of the engine.
2. Pull out the dipstick, and wipe it clean with a rag.
3. Reinsert the dipstick and push it in as far as it will go, or the
reading will not be correct.

4. Pull the dipstick out and look at the oil level on the end. If
it is between the low level mark ( 4 ) and the full level mark
( 5 ), it is O.K.
SV62003
If the oil level is below or only slightly above the low level
mark, add engine oil of the same type as already in the
engine.
Remove the oil filler cap and add engine oil a little at a time,
checking the dipstick. The approximate quantity of oil needed
to fill between the low level mark and the full level mark on the
dipstick is indicated below for reference.
When the level reaches within the correct range, return the
filler cap and turn the cap clockwise until you hear a click.
Oil quantity. L (qt., lmp. qt.) 1.5 (1.6, 1.3)
NOTICE
Avoid overfilling, or the engine could be damaged. Check the oil level on the dipstick once again afteradding the oil.

Engine oil selection
Use API SJ, ºEnergy±Conservingº multigrade engine oil or
ILSAC multigrade engine oil.
Recommended viscosity (SAE):
62L005±1
Temperature range anticipated before next oil change
SAE 5W±30 is the best choice for your vehicle, for good
fuel economy and good starting in cold weather.
If you use SAE 10W±30 engine oil in extremely low
temperatures, the engine may become difficult to start, so
SAE 5W±30 engine oil is recommended.
Oil identification marks
62L006±1

API Service Symbol
ILSAC Certification Mark
Either or both API registered marks are added to some oil
containers to help you select the oil you should use.
 The API Service Symbol is located anywhere on the outside
of the container.
The top portion of the label shows the oil quality by API
(American Petroleum Institute) designation such as SJ.
The center portion of the label shows the SAE viscosity
grade such as SAE 5W±30. ºEnergy±Conservingº, shown
in the lower portion, indicates that the oil has fuel±saving
capabilities.
 The ILSAC (International Lubricant Standardization and
Approval Committee) Certification Mark is displayed on the
front of the container.

*Change automatic transmission fluid only as necessary.
Generally, it is necessary to change automatic transmission
fluid only if your vehicle is driven under one of the Special
Operating Conditions listed in your ºOwner's Manual
Supplement / Maintenance Scheduleº. When changing the
automatic transmission fluid, use only Toyota Genuine ATF
Type T±IV ( ATF JWS3309 or NWS6500) to aid in assuring
optimum transmission performance.NOTICE
Using automatic transmission fluid other than Toyota Genuine ATF T ype T±IV may cause deterioration in shift
quality, locking up of your transmission accompanied by vibration, and ultimately damage the automatictransmission of your vehicle.

CHECKING BATTERY CONDITION
Precautions
CAUTION
BATTERY PRECAUTIONS
The battery produces flammable and explosive
hydrogen gas.
Do not cause a spark by contacting the battery
terminals with tools.
 Do not smoke or light a match near the battery.
The electrolyte contains poisonous and corrosive
sulfuric acid.
 Avoid contact with eyes, skin or clothes.
 Never inhale or swallow electrolyte.
 Wear protective safety glasses when working near
the battery.
 Keep children away from the battery.
EMERGENCY MEASURES
 If electrolyte gets in your eyes, flush your eyes with
clean water for at l east 15 minutes and get immediate
medical attention. If possible, continue to apply
water with a sponge or cloth while traveling to the
medical office.
 If electrolyte gets on your skin, thoroughly wash the
contacted area. If you feel a pain or burn, get medical
attention immediately.
 If electrolyte gets on your clothes, there is a
possibility of its soaking through to your skin, so
immediately take off the exposed clothing and follow
the procedure above, if necessary.
 If you accidentally swallow electrolyte, drink a large
quantity of water or milk. Follow with milk of
magnesia, beaten raw egg or vegetable oil. Then go
immediately for emergency help.

NOTICE

If a stain should fail to come out with a neutraldetergent, apply a cleaner that does not contain anorganic solvent.

Never use organic substances such as benzine,alcohol or gasoline, or alkaline or acid solutions forcleaning the leather as these could causediscoloring.

Use of a nylon brush or synthetic fiber cloth, etc. mayscratch the fine grained surface of the leather.

Mildew may dev elop 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 yourvehicle in a shaded area, especially in the summer.

The interior of your vehicle is apt to heat up on hotsummer days, so avoid placing on the upholstery
items made of vinyl or plastic or containing wax asthese tend to stick to leather when warm.

Improper cleaning of the leather upholstery couldresult in discoloration or staining.
If you have any questions about the cleaning of your
Lexus, your local Lexus dealer will be pleased to answer
them.
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 weakenthem.

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, becareful not to scratch or damage the heater wires.
