It is not, it indicates the specific parkinglot  to acces to get to the actual playground (200m to the south). Sorry, didn't know how to indicate it otherwise. Please find a proper way to indicate that this is the only(!) parkinglot to acces the playground by car if you pan to visit it specifically.  The info on the Munich Airport website, nor the Info on the Phone indicated the right car access. It is very difficult to find it otherwise, since the airport has many parkinglots with a wide variaty of pricing options (often only daily tarif).
