Water could enter and remain in the seam inside the rear lid. If it is cold outside, the vehicle must be placed in a warm room until the lid warms up to room temperature. Repair Procedure: 1. Open the rear lid. 1.1 Completely cover the rear of the vehicle (engine, fenders, window etc.) with paper or plastic film. Caution! The covering must be placed completely underneath the open lid in order to catch any dripping anti-corrosion fluid. If the vehicle is a cabriolet, make sure the fabric and rear window is completely covered. The anti-corrosion fluid and wax preservative could stain it. 1.2 Shake the spray can vigorously before use. 1.3 Spray the anti-corrosion fluid on the following areas on the inside of the rear lid. When spraying, hold the nozzle (the tube) of the spray can against the edge of the seam.Start by spraying on the seam on the left and right sides, from the lid hinge to the rear edge (arrows a, figure 1). Then spray from one corner of the rear folded seam to the other (arrow b, figure 1). 1.4 Allow the sprayed on anti-corrosion fluid to act for approximately 1 minute. Afterwards, wipe away excess anti-corrosion fluid with a lint-free cloth. Wipe the folded seam as well. Date: 02-09-01 ©2001 Porsche Cars North America, Inc. Page 4 of 10 Service
