Bought my XC90 through Oversea Delivery program (OSD). When I was driving it in Sweden, the engine stops at a full stop and then as soon as I release my foot from the break, the engine restarts, and by the time my foot is on the gas pedal, the engine is ready to go. Yesterday I took delivery of it at the dealer and drove it home and noticed that now when I release my foot from the break, the engine still stopped. Only when I begin to push on the gas pedal, the engine starts and then a second or two later it is ready to move. I wonder what is other owner's experience with engine stop/start. I am perfectly happy with the way it worked in Sweden, but concerned with its current behavior as when my feet is on the pedal, I expect the car ready to move, not having to delay another second to get ready. Could this be caused by the software switch from European to U.S. settings?
