If your vehicle is certified to meet California Emission
Standards (indicated on the underhood tune-up label),
it is designed to operate on fuels that meet California
specifications. If such fuels are not available in states
adopting California emissions standards, your vehicle
will operate satisfactorily on fuels meeting federal
specifications, but emission control system performapce
may be affected. The malfunction indicator lamp on
your instrument panel may
turn on and/or your vehicle
may fail a smog-check test. If this occurs, return to your
authorized Pontiac dealer for diagnosis to determine the
cause of failure. In the event it is determined that the
cause of the condition
is the type of fuels used, repairs
may not be covered by your warranty.

To provide cleaner air, all gasolines are now required to
contain additives that will help prevent deposits from
forming in your engine
and fuel system, allowing your
emission control system to function properly. Therefore,
you should not have to add anything to the fuel. In
