repairer, or another duly qualified and equipped professional.
If the fans are operating:
Have the vehicle inspected at the nearest any authorized Lexus dealer or
repairer, or another duly qualified and equipped professional.

Oil viscosity (0W-20 is explained here as an example):
• The 0W in 0W-20 indicates the characteristic of the oil which allows cold
startability. Oils with a lower value before the W allow for easier starting of
the engine in cold weather.
• The 20 in 0W-20 indicates the viscosity characteristic of the oil when the
oil is at high temperature. An oil with a higher viscosity (one with a higher
value) may be better suited if the vehicle is operated at high speeds, or
under extreme load conditions.
How to read oil container labels:
Either or both API registered marks are added to some oil containers to help
you select the oil you should use.
API Service Symbol
Top portion: “API SERVICE SN” means the oil quality designation by
American Petroleum Institute (API).
Center portion: “SAE 0W-20” means the SAE viscosity grade.
Lower portion: “Resource- Conserving” means that the oil hasfuel-saving and environmental pro-
tection capabilities.
ILSAC Certification Mark
The International Lubricant Specificatio n Advisory Committee (ILSAC) Certifica- tion Mark is displayed on the front of the container.
