I thought the seat adjustments were on the door. 1,2 and set. If I remember correctly the salesperson said you could also use your key fob to set the seat so it remembered who was sat on number 1 and also number 2. I’m sure when I watched YouTube videos they showed you how to adjust and set.
so get the seat in the right position, press the set button then either 1 or 2 depending on which numbered key you are using. It’s full memory along with the wing mirrors as well.
