Care of the seat belts
If it becomes necessary to clean the belts, you
can use any mild washing agent. Allow the belts
to dry prior to retracting, but avoid direct
sunlight.
If unsuitable cleaners are used or any attempt is
made to dye or bleach the belts, the webbing
may be weakened and thus constitute a safety
risk.
Storing your Porsche Vehicle
If you intend to store your Porsche for a pro-
longed period, please consult your authorized
Porsche dealer. The staff will be glad to advise
you on the most suitable and necessary
methods.
