Involved vehicles have been identified by Vehicle Identification Number Computer Listings. Computer listings contain the complete Vehicle

furnished will enable dealers to follow-up with owners involved in this campaign.
These listings may contain owner names and addresses obtained from State Motor vehicle Registration Records. The use of such motor vehicle
registration data for any other purpose is a violation of law in several states. Accordingly, you are urged to limit the use of this listing to the follow-up
necessary to complete this campaign. Any dealer not receiving a computer listing with the campaign bulletin has no involved vehicles currently assigned.
OWNER NOTIFICATION
Owners will be notified of this campaign on their vehicles by Chevrolet Motor Division (see copy of owner letter included with this bulletin).
DEALER CAMPAIGN RESPONSIBILITY
Dealers are to service all vehicles subject to this campaign at no charge to owners, regardless of mileage, age of vehicle, or ownership, from this time
forward.
Whenever a vehicle subject to this campaign is taken into your new or used vehicle inventory, or it is in your dealership for service in the future, you
should take the steps necessary to be sure the campaign correction has been made before reselling or releasing the vehicle.
If there is evidence of intentional disablement of the evaporative emission system, the dealer is to notify the vehicle owner of this condition and ask if
he/she wants the system restored. The cost of such restoration will be the responsibility of the owner.
