A few questions about my first Suzuki (Alto)

Moinsen municipality, I have now got my first Suzuki, an Alto bj 2011. Since I come from the VW and BMW front, I have a few questions to the connoisseurs here. I can pick up the Alto only next weekend, and thus I have no service booklet, manual or anything at my hand. I buy the car with fresh TÜV, but the inspection is due, but I do it myself (as with all my vehicles) simply to save some money. At VW, BMW, Opel u bw there are certain oil releases. Which ones do I have to stick to with my new sweetheart? Have read the many 5w30 take, other 10w40 but more important is the release like acea A3, vw 505 00 or so. What release do I need with the Suzuki? What change interval does such an Alto of oil, spark plugs etc? From the belly I would drive 15000km the oil and 80-100000km the spark plugs. Is there something I should pay attention to? Must admit, had never had experience with Suzuki, but somehow I fell in love with the little excited greetings from the far north
