The Catalog tab displays the Select a Vehicle screen that is used to perform Catalog Lookups. The user defines the Year, Make, Model and Engine size of a desired vehicle or, if applicable, selects a previously defined vehicle. The user then selects a part Group and one or more Subgroups to go forward with a Catalog Lookup, or uses the Smart Search™ feature for quick lookups. All parts that meet the selection criteria display in the Catalog Part Display results screen.
