Lubrication system■ Engine oil selection
“Toyota Genuine Motor Oil” is used in your Lexus vehicle. Use Lexus
approved “Toyota Genuine Motor Oil” or equivalent to satisfy the follow-
ing grade and viscosity.
Oil grade: ILSAC multigrade engine oil
Recommended viscosity: SAE 5W-30
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 oil may be used.
However, it should be replaced
with SAE 5W-30 at the next oil
change.
The 5W portion of the oil viscosity rating indicates a characteristic of the oil
which allows cold startability. Oils with a lower value before the W allow for eas-
ier starting of the engine in cold weather.
The 30 in 5W-30 indicates the oil viscosit y when the oil is at its operating tem-
perature. An oil with a higher viscosity may be better suited if the vehicle is oper-
ated at high speeds, or un der extreme load conditions.

■Temperature A, B, C
The temperature grades are A (the hi ghest), B, and C, representing
the tire's resistance to the generation of heat and its ability to dissipate
heat when tested under controlled conditions on a specified indoor
laboratory test wheel.
Sustained high temperature can cause the material of the tire to degenerate
and reduce tire life, and excessive temperature can lead to sudden tire fail-
ure.
The grade C corresponds to a level of performance which all passenger car
tires must meet under the Federal Mo tor Vehicle Safety Standard No. 139.
Grades B and A represent higher levels of performance on the laboratory
test wheel than the minimum required by law.
Warning: The temperature grades for this tire are established for a tire that
is properly inflated and not overloaded.
Excessive speed, underinflation, or excess ive loading, either separately or in
combination, can cause heat build up and possible tire failure.
