by the New Vehicle Limited Warranty. The availability of courtesy transportation to customers whose vehicles are within the warranty coverage period
and involved in a product program is very important in maintaining customer satisfaction. Dealers are to ensure that these customers understand that
shuttle service or some other form of courtesy transportation is available and will be provided at no charge. GM Dealers should refer to the General
