Hello together, as an interested newcomer and candidate of a new 508 SW (May 2019) I would have liked to know if the optional Webasto floor heating also functions as a stand ventilation in the summer?! It obviously has numerous functions and adjustment options. But from the operating instructions e.g. of the 5008 unfortunately does not show whether the lowest heating level is not at all, but only ventilated (page 109)?! Also on the pages of the Peugeot accessory nothing can be found?! Please feedback a knowledge Thank you in advance.
