furnished will enable dealers to follow-up with owners involved in this campaign.

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

the steps necessary to be sure the campaign correction has been made before reselling or releasing the vehicle.
