Engine oil consumption
It is normal that an engine should consume some engine oil during normal
engine operation. The causes of oil consumption in a normal engine are
as follows.
Oil is used to lubricate pistons, piston rings and cylinders. A thin film of
oil is left on the cylinder wall when a piston moves downwards in the
cylinder. High negative pressure generated when the vehicle is
decelerating sucks some of this oil into the combustion chamber. This oil
as well as some part of the oil film left on the cylinder wall is burned b\
y the
high temperature combustion gases during the combustion process.
 Oil is also used to lubricate the stems of the intake valves. Some of this\
oil
is sucked into the combustion chamber together with the intake air and i\
s
burned along with the fuel. High temperature exhaust gases also burn the
oil used to lubricate the exhaust valve stems. 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 cyli\
nder
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 t\
he
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 198.

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 pr olonged 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
62E001±1
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 turni\
ng
off the engine, wait a few minutes for the oil to drain back into the bott\
om 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 full line (
5 ) and the low line ( 4 ), it is O.K.
62E003±1
If the oil level is below or only slightly above the low line, add engin\
e 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 line
and the full line on the dipstick is indicated below for reference.
When the level reaches within the correct range, return the filler cap and t\
urn
the cap clockwise until you hear a click.

NOTICE
Avoid overfilling, or the engine could be damaged. Check the oil level on
the dipstick once again after adding the oil.

Engine oil selection
Use API SH, ºEnergy±Conserving IIº or 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.

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 least 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 happen to 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.

BODY237
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 off 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 hardeni\
ng or
shrinking of the leather.
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 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.
