NO: 83-40DATE: 5-15-2007

SUBJECT:
Tonneau Cover Marks
REFERENCE:
VIDA
DESCRIPTION:
Several cases of circular marks on the tonneau cover have been reported. The marks are located along the rear edge of the cover and have a dark brown shade (see picture shown). The root cause has been determined to be solvents in the rubber bumpers that come into contact with the cover, therefore new bumpers have been introduced from chassis number 014426. Contact between the bumpers and the tonneau cover can be caused by incorrect adjustment of the tonneau cover hard stops.
Note:
Due to bouncing of the tonneau cover even with a correct stop adjustment a touching condition may still occur when the trunk lid is slammed.
