The API Service Symbol is located anywhere on the outside
of the container.
The top portion of the label shows the oil quality by API
(American Petroleum Institute) designation such as SL.
The center portion of the label shows the SAE viscosity
grade such as SAE 5W±30. ºEnergy±Conservingº, shown
in the lower portion, indicates that the oil has fuel±saving
capabilities.
 The ILSAC (International Lubricant Standardization and
Approval Committee) Certification Mark is displayed on the
front of the container. To ensure excellent lubrication performance for your engine,
the ºToyota Genuine Motor Oilº range is available, which has

CHECKING TIRE PRESSURE
SV61004
The recommended cold tire pressures, tire size and the
vehicle capacity weight are given on the label.
You should check the tire pressures every two weeks, or at
least once a month. And don't forget the spare! The pressure
for the spare tire should be the same with that for the standard
tire. Incorrect tire pressure may waste fuel, reduce the comfort
of driving, reduce tire life and make your vehicle less safe to
drive.
If a tire needs frequent refilling, have it checked by your Lexus
dealer.
