2001 Lexus ES300 oil dipstick

GAUGES, METERS AND SERVICE REMINDER INDICATORS
64
(e) Low Oil Pressure Warning Light
This light warns that the engine oil pressure is too low.
If it flickers or stays on while you are driving, pull off the
road to a safe place and stop the engine immediately.
Call a Lexus dealer or qualified repair shop for
assistance.
The light may occasionally flicker when the engine is
idling or it may come on briefly after a hard stop. There
is no cause for concern if it then goes out when the
engine is accelerated slightly.
The light may come on when the oil level is extremely
low. It is not designed to indicate low oil level, and the
oil level must be checked using the oil level dipstick.
NOTICE
Do not drive the vehicle with the warning light on± even for one block. It may ruin the engine.
(f) Low Engine Oil Level Warning Light
This light warns that the engine oil level is too low. Add
oil as soon as possible. (For instructions, see ªChecking
the engine oil levelº on page 410.)
While driving on steep inclines or rough roads which
causes the vehicle to substantially sway or on curves,
this light may come on due to the movement of engine
oil in the engine.
NOTICE
Continued engine operation with low engine oilwill damage the engine.
(g) Malfunction Indicator Lamp
This lamp comes on in the following cases.
a. The fuel tank is completely empty. (See ªFuel gaugeº on page 54 for instructions.)
b. The fuel tank cap is not tightened securely. (See ªFuel tank capº on page 108 for instructions.)
c. There is a problem somewhere in your engine or automatic transmission electrical system.
If it comes on while you are driving in case ªc.º, have your
vehicle checked/repaired by your Lexus dealer as soon
as possible.

MAINTENANCE
384
Engine compartment
Items listed below should be checked from time to
time, e.g. each time when refueling.
Washer fluid
Make sure there is sufficient fluid in the tank. See page
464 for additional information.
Engine coolant level
Make sure the coolant level is between the ªFULLº and
ªLOWº lines on the see±through reservoir when the
engine is cold. See page 415 for additional information.
Battery
Your Lexus has a maintenance free battery. You do not
have to add distilled water. For longer life of the battery,
however, see page 451 for additional information.
Brake fluid level
Make sure the brake fluid level is correct. See page 424
for additional information.
Engine oil level
Check the level on the dipstick with the engine turned off
and the vehicle parked on a level spot. See page 410 for
additional information.
Power steering fluid level
Check the level through the reservoir. The level should
be in the ªHOTº or ªCOLDº range depending on the fluid temperature. See page 426 for additional information.
Exhaust system
If you notice any change in the sound of the exhaust or
smell exhaust fumes, have the cause located and
corrected immediately.
(See engine exhaust cautions in
Section 3±1.)

FACTS ABOUT ENGINE OILCONSUMPTION
Functions of engine oil
Engine oil has the primary function of lubricating and
cooling the inside of the engine, and plays a major role
in maintaining the engine in proper working order.
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 by 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 is 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 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.

CHECKING THE ENGINE OILLEVEL
62E009
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.

ENGINE
413
If the oil level is below or only slightly above the low
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.

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