The total number of days possible is 7 days. You have to find an alternative parking. Without the information on where you intend to park the car, it is difficult for us to offer help.
I, however, wondered why you have to park the car for so many days? I am not sure if you are aware that parking a car in Switzerland is a costly undertake; expect parking fees of about CHF 30 per day, if not more.
My personal advice therefore, whenever possible, try to avoid using the car. Again, we might be able to help you find another mean of transport would we know what your plans are.
