With the Tarraco in the washing machine

Hello, I have been the proud owner of a Seat Tarraco for a few days now. Now I would like to drive by car through the wash road on site, which has already been visiting with my previous car for years. At the wash road you get off at the beginning and the car is pulled through the system. I hope you understand what I mean. My previous car had no assistance systems etc. I know the general information: automatic on N, mirror charges etc. However, I am uncertain about all the technical gimmicks and helpers, what I have to pay attention to or what I have to deactivate everything before. I have thought about the electronic parking brake, the automatic braking of the shunting assistant etc. In the operating instructions and on the Internet I have unfortunately found no instructions or checklist. And I forgot a little bit about anything and then to worry about an embarrassing and possibly expensive situation. I would be super grateful if someone could help me. Thanks already.
