AIR INDEX
(Models certified for sale in California)
An Air Index Information label is applied to engines certified to an emission
durability time period in accordance with the requirements of the California Air
Resources Board.
The bar graph is intended to provide you, our customer, the ability to compare
the emissions performance of available engines. The lower the Air Index, the
less pollution.
The durability description is intended to provide you with information relating
to the engine’s emission durability period. The descriptive term indicates the
useful life period for the engine’s emission control system. See your "Emission
Control System Warranty" (see page 90) for additional information.
