INTRODUCTION
A. Important Vehicle Owner Advisories:
•
At the time of this writing, the Sequent P&D system has not been certified by the California Air
Resources Board (CARB). If the vehicle is moved to California, it may not be registered
without returning the vehicle to as-close-as-possible to original condition. Please inform the
customer that emissions standards vary state to state and to check with the emissions
enforcement agency or DMV prior to moving the vehicle into another state. IMPCO is
pursuing a (CARB) certification. Contact IMPCO for certification status and updates.
•
The EPA certification on the 2009 GM 3.5/3.9L Impala covers vehicles with the E85 fuel
option. It is important that the vehicle be run on gasoline with a maximum of 10%
alcohol content with the Plug & Drive system. Operation on E85 fuel may cause rough
engine running and possible check engine light illumination during or shortly after the
changeover to CNG operation. Please advise your customers before installing the
system.
