Maintenance and care
CAUTION
The engine compartment contains many mechanisms and fluids that may move sud-
denly, become hot, or become electrically energized. To avoid death or serious injury.
■When working on the engine compartment
●Keep hands, clothing, and tools away from the moving fan and engine drive belt.
●Be careful not to touch the engine, inverter, radiator, exhaust manifold, etc. right
after driving as they may be hot. Oil and other fluids may also be hot.
●Do not leave anything that may burn easily, such as paper or rags, in the engine
compartment.
●Do not smoke, cause sparks or expose an open flame to fuel or the battery. Fuel
and battery fumes are flammable.
●Be extremely cautious when working on the battery. It contains poisonous and
corrosive sulfuric acid.
■When working near the electric cooling fan or radiator grille
Be sure the ignition switch is in “LOCK”.
With the ignition switch is in the “ACC” or “ON” position, the electric cooling fan
may automatically start to run if the air conditioning is on and/or the coolant tem-
perature is high. ( P. 295)
■Safety glasses
Wear safety glasses to prevent flying or falling material, fluid spray, etc. from getting
in the eyes.
NOTICE
■If you remove the air cleaner filter
Driving with the air cleaner filter removed may cause excessive engine wear due to
dirt in the air. Also a backfire could cause a fire in the engine compartment.

■Recommended viscosity
SAE 5W-30 is the best choice for
good fuel economy and good
starting in cold weather.
*: If SAE 5W-30 is not available,SAE 10W-30 may be used.
However, it should be replaced
with SAE 5W-30 at the next oil
change.
■ How to read oil container labels
Some oil containers are labeled wi th ILSAC certification marks that
help you to select the proper oil.

■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 consumpt ion, 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 the vehicle consumes more than this amount, contact your Lexus dealer.
■Resetting the engine oil main tenance data (U.S.A. only)
Perform the following steps: Switch the display to the odometer. ( P. 1 0 3 )
