(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 ºChecking 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 ºFacts 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 reminds you when to replace the engine oil.
This light will come on when the ignition key is turned to the
ºONº 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 ºONº 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 ºONº 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 ºOFFº position with the odometer
reading shown. (For details, see ºOdometer and trip meterº on
page 48.)
2. Turn the ignition key to the ºONº position while holding down
the ºODO/TRIPº button.
Hold down the button for at least 5 seconds. The odometer
indicates º000000º 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.

MAINTENANCE REQUIREMENTS
Your Lexus vehicle has been designed for fewer maintenance
requirements with longer service intervals to save both your
time and money. However, each regular maintenance as well
as day-to-day care is more important than ever before to
ensure smooth, trouble-free, safe, and economical driving.
It is the owner's responsibility to make sure the specified
maintenance, including general maintenance services, is
performed. Note that both the new vehicle and emission
control system warranties specify that proper maintenance
and care must be performed. See ºOwner's Guideº, ºOwner's
Manual Supplementº or ºWarranty Bookletº for complete
warranty information.
General maintenance
General maintenance items are those day-to-day care
practices that are important to your vehicle for proper
operation. It is the owner's responsibility to ensure that the
general maintenance items are performed regularly.
These checks or inspections can be done either by yourself or
your Lexus dealer.
Scheduled maintenance
The scheduled maintenance items listed in the ºOwner's
Manual Supplement / Scheduled Maintenanceº are those
required to be serviced at regular intervals.
For details of your maintenance schedule, read the ºOwner's
Manual Supplement / Scheduled Maintenanceº.
It is recommended that only genuine Lexus parts be used
for maintenance.
The owner may elect to use non-Lexus supplied parts for
replacement purposes without invalidating the emission
control system warranty. However, use of replacement
parts which are not of equivalent quality may impair the
effectiveness of the emission control systems.
You may also elect to have maintenance, replacement, or
repair of the emission control devices and system
performed by any automotive repair establishment or
individual without invalidating this warranty. See
ºOwner's Guideº, ºOwner's Manual Supplementº or
ºWarranty Bookletº for complete warranty information.
