(g) 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 333.)
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.
In normal conditions, due to engine oil consumption, this light
may come on earlier than the specified service interval of the
scheduled maintenance. This is because the engine oil is
consumed to the low level within the scheduled maintenance
interval and does not indicate a problem. (For detailed
information, see ªFacts about engine oil consumptionº on page
331.)
NOTICE
Continued engine operation with low engine oil will damage the engine.
(h) Engine Oil Replacement Reminder Light (for vehicles sold in U.S.A.)
This light acts as a reminder to replace the engine oil.
This light will come on when the ignition key is turned to the
ªONº position and will go off after about a few seconds. When you drive for about 7200 km (4500 miles) after the
engine oil replacement, this light illuminates for about 3
seconds and then flashes for about 12 seconds with the
ignition key turned to the ªONº position. If you continue driving
without replacing the engine oil, and if the distance driven
exceeds 8000 km (5
000 miles), the light will come on after the
ignition key is turned to the ªONº position. The light will remain
on thereafter.
If the light is flashing, we recommend that you replace the
engine oil at an early opportunity depending on the driving and
road conditions. If the light comes on, replace it as soon as
possible.
The system must be reset after the engine oil replacement.
Reset the system by the following procedure:
1. Turn the ignition key to the ªOFFº position with the odometer
reading shown. (For details, see ªOdometer and trip meterº on
page 48.)
2. Turn the ignition key to the ªONº position while holding down
the ªODO/TRIPº button.
Hold down the button for at least 5 seconds. The odometer
indicates ª000000º and the light goes off.
If the system fails to reset, the system will revert to the state
before resetting operation. In this case, return to step 1 and try
again.

ENGINE
332The 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.
Oil consumption:
Max. 1.0L per 1000 km (1.1 qts./600 miles,
0.9 Imp. qts./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 ªChecking the
engine oil levelº on page 333.

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 correct reading, the vehicle should be on level
ground. After turning off the engine, wait a few minutes for the
oil to drain back into the bottom of the engine.
2. Pull the dipstick out, hold a rag under the end and wipe it
clean.
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 while holding a
rag under the end. If it is between the low level mark ( 4 ) and
the full level mark ( 5 ), it is O.K.
NOTICE
Be careful not to drop engine oil on the vehicle
components.
SV62008
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. We recommend that you use a funnel
when adding oil.
The approximate quantity of oil needed to raise the level
between low and full 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.
