Reminder light
W40W40
When the engine oil pressure becomes too low, the
above message appears, the reminder light flashes
and the warning tone sounds.
If this message appears 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 message may appear 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 messagedisplayed ± even for one block. It may ruin theengine.

Engine oil level
Check
the level on the dipstick with the engine turned off
and the vehicle parked on a level spot. See page 413 for
additional information.
Power steering fluid level
Check the level on the dipstick. The level should be in
the ºHOTº or ºCOLDº range depending on the fluid
temperature. See page 428 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.)
DOES YOUR VEHICLE NEED REPAIRING?
Be on the alert for changes in performance and sounds,
and visual tip±offs that indicate service is needed. Some
important clues are:

Engine missing, stumbling, or pinging

Appreciable loss of power

Strange engine noises

A fluid leak under the vehicle (However, water
dripping from the air conditioning after use is normal.)

Change in exhaust sound (This may indicate a
dangerous carbon monoxide leak. Drive with the
windows open and have the exhaust system checked
immediately.)

Flat±looking tires, excessive tire squeal when
cornering, uneven tire wear

Vehicle pulls to one side when driving straight on a
level road

Strange noises related to suspension movement

Loss of brake effectiveness, spongy feeling brake
pedal, pedal almost touches floors, vehicle pulls to
one side when braking

Engine coolant temperature continually higher than
normal

410combustion 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 by high±speed driving 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
62L004a
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 line ( 4 ) and the full level
line ( 5 ), it is O.K.

If the oil level is below or only slightly above the low
line,
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 line and the full
level line 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.
