Sometimes, changing the position of the seat, when I approach the car. What is the explanation?

 

Use different keys sometimes?

 

Each key remembers the last seat position, radio. and climate you shut the car with so if you switch keys to unlock your car it'll move back to the same settings the last time it was driven with. Intention was so you and a spouse can each have a key and have their own personal setting

 

I think not. I think I used the usual key. Happened to me once when I was out shopping ... So I used the same key that I locked the car.
