Maintenance and care
■Engine oil consumption
●The amount of engine oil consumed depends on the oil viscosity, the quality of
the oil and the way the vehicle is driven.
●More oil is consumed under driving conditions such as high speeds and fre-
quent acceleration and deceleration.
●A new engine consumes more oil.
●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.
●Oil consumption: Max. 1.1 qt./600 miles, 0.9 lmp. qt./600 miles (1.0 L per 1000
km)
●If you consume more than 1.1 qt. (1.0 L, 0.9 lmp. qt.) every 600 miles (1000 km),
contact your Lexus dealer.
■Changing the engine oil (USA only)
To reset the oil change system, follow the procedure below:
Turn the “ENGINE START STOP” switch OFF with the trip meter A read-
ing shown. (→P. 1 3 6 )
While pressing the trip meter reset button, set the “ENGINE START
STOP” switch to the IGNITION ON mode. Continue to press and hold
the button until the trip meter displays “000000”.
CAUTION
■Used engine oil
●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. To remove used engine oil from your skin, wash
thoroughly with soap and water.
●Dispose of used oil and filters only in a safe and acceptable manner. Do not dis-
pose of used oil and filters in household trash, in sewers or onto the ground.
Call your Lexus dealer, service station or auto parts store for information con-
cerning recycling or disposal.
●Do not leave used engine oil within the reach of children.

CAUTION
■When replacing wheels
●Do not use wheels that are a different size from those recommended in the
Owner’s Manual, as this may result in loss of handling control.
●Never use an inner tube in a leaking wheel which is designed for a tubeless tire.
Doing so may result in an accident, causing death or serious injury.
NOTICE
■Replacing tire pressure warning valves and transmitters
●Because tire repair or replacement may affect the tire pressure warning valves
and transmitters, make sure to have tires serviced by your Lexus dealer or other
qualified service shop. In addition, make sure to purchase your tire pressure
warning valves and transmitters at your Lexus dealer.
●Ensure that only genuine Lexus wheels are used on your vehicle.
Tire pressure warning valves and transmitters may not work properly with non-
genuine wheels.

4-3. Do-it-yourself maintenance
■Checking interval
Inspect, clean and replace the air conditioning filter according to the maintenance
schedule. In dusty areas or areas with heavy traffic flow, more frequent cleaning or
early replacement may be required. (For scheduled maintenance information,
please refer to the “Warranty and Services Guide/Owner's Manual Supplement/
Scheduled Maintenance”.)
■If air flow from the vents decreases dramatically
The filter may be clogged. Check the filter and replace if necessary.
NOTICE
■To prevent damage to the system
●When using the air conditioning system, make sure that a filter is always installed.
●When cleaning the filter, do not clean the filter with water.
■Cleaning method
If the filter is dirty, clean by blow-
ing compressed air through the
filter from the downward side.
Hold the air gun 2 in. (5 cm)
from the filter and blow for
approximately 2 minutes at 72
psi (500 kPa, 5.0 kgf/cm
2 or
bar).
If it is not available, have the filter
cleaned by your Lexus dealer.
