●Do not use wheels that are a different size from those recommended in the Owner’s
Manual, as this may result in a 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 se rviced by any authorized Lexus retailer or
Lexus authorized repairer, or any reliable repairer or other qualified service shop. In addition, make sure to purchase your tire pressure warning valves and transmitters at
any authorized Lexus retailer or Lexus author ized repairer, or any reliable repairer.

strikes the bottom of the vehicle.
■To avoid damage to the tire pressure warning valves and transmitters

6489-1. Specifications
IS300h_EE(OM53D89E)
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 viscos ity 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 lo ad conditions.
How to read oil container labels:
Either or both API registered marks ar e 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-Conserv-
ing” means that the oil has fuel-saving
and environmental protection capa- bilities.
ILSAC Certification Mark
The International Lubricant Specificatio n Advisory Committee (ILSAC) Certifica-
tion Mark is displayed on the front of the container.
