#### SUBJECT: 96060 - TEMPORARY ROOF PANEL DISTORTION ------------------------------------------------

#### MODELS: CERTAIN 1997 CADILLAC DEVILLE VEHICLES BUILT WITHOUT ---------------------------------------------------- OPTIONAL FACTORY INSTALLED SUNROOF (RPO CF5) --------------------------------------------

This bulletin replaces previous DCS Administrative Messages dated August 30, 1996; September 3, 1996; and September 5,1996 regarding this subject.

General Motors has decided that certain 1997 Cadillac DeVille, DeVille Concours, and DeVille d'Elegance model vehicles NOT equipped with optional factory installed sunroof (RPO CF5) may exhibit a condition in which, depending upon exposure to higher exterior temperatures, the roof panel temporarily becomes distorted. Typically, this condition appears as slight depressions of the roof panel in the area over the front seating positions. To prevent the possibility of this condition occurring, dealers are to lower the headliner and modify the composite membrane (cardboard roof dampener) attached to the roof panel according to the Service Procedure in this bulletin.

#### VEHICLES INVOLVED:

Involved are certain 1997 Cadillac DeVille, DeVille Concours, and DeVille d'Elegance model vehicles NOT equipped with optional factory installed sunroof (RPO CF5) and built within the following VIN breakpoints:

PLANT YEAR DIVISION MODEL PLANT CODE FROM THROUGH ---- -------- ------- --------- ----- --------- -------- 1997 Cadillac DeVille Hamtramck "U" VU200001 VU211748

#### NOTICE: Dealers should confirm vehicle eligibility through VISS (Vehicle Information Service System) prior to beginning campaign repairs. Not all vehicles within the above breakpoints are involved. Our records indicate that 510 vehicles were corrected at the assembly plant and are not included in this campaign.

Involved vehicles have been identified by Vehicle Identification Number. Computer listings containing the complete Vehicle Identification Number, customer name and address data have been prepared, and are being furnished to involved dealers with the campaign bulletin. The Customer name and address data furnished will enable dealers to follow-up with customers involved in this campaign. Any dealer not receiving a computer listing with the campaign bulletin has no involved vehicles currently assigned.

These dealer listings may contain customer 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.

#### CUSTOMER NOTIFICATION

Affected customers will be notified of this campaign on their vehicles by letter from Cadillac Motor Car Division. A copy of the customer letter is included with this bulletin.

#### COURTESY TRANSPORTATION

The availability of courtesy transportation to customers whose vehicles are involved in this campaign is of the utmost importance in maintaining customer satisfaction. Dealers are to take the steps necessary to ensure that these customers clearly understand that courtesy transportation is available and will be provided upon request at no charge. Dealers should submit such claims in the normal manner and appropriate credit will be issued.

#### DEALER CAMPAIGN RESPONSIBILITY

All unsold new vehicles in dealers' possession and subject to this campaign must be held and inspected/repaired per the service procedure of this campaign bulletin before customers take possession of these vehicles.

Dealers are to service all vehicles subject to this campaign at no charge to customers, regardless of mileage, age of vehicle, or ownership, from this time forward.

Customers who have recently purchased vehicles sold from your vehicle inventory, and for which there is no customer information indicated on the dealer listing, are to be contacted by the dealer. Arrangements are to be made to make the required correction according to the instructions contained in this bulletin. This could be done by mailing to such customers a copy of the appropriate divisional customer lefter accompanying this bulletin. Campaign follow-up cards should not be used for this purpose, since the customer may not as yet have received the notification lefter.

In summary, whenever a vehicle subject to this campaign enters your vehicle inventory, or is in your dealership for service in the future, please take the steps necessary to be sure the campaign correction has been made before selling or releasing the vehicle.

#### PARTS INFORMATION:

If the section to be reattached is one of the two outermost sections on either side, use a single bead running down the center of the membrane. If the middle section of membrane requires reattachment, use 2 beads of adhesive centered approximately 6 inches apart. It may also be necessary to remove some original adhesive from the membrane and/or roof panel to insure proper adhesion.

Betamate Urethane Adhesive will not be available from General Motors Service Parts Operations (GMSPO) until approximately January 1, 1997. When it does become available from GMSPO, the GM Part Number for this adhesive will be 12378192.

General Motors bulletins are intended for use by professional technicians, not a "do-it-yourselfer". They are written to inform those technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions and know-how to do a job properly and safely. If a condition is described, do not assume that the bulletin applies to your vehicle, or that your vehicle will have that condition. See a General Motors dealer servicing your brand of General Motors vehicle for information on whether your vehicle may benefit from the information.
