Hey Michael you can choose your pit strategie in the first setup page. Just set your number of pitstops and the litres of fuel you want to refill in each stop. Then in the race it will do the strategie you created with automatical refilling. If you want to change your tire compound at a pitstop you will have to call the pit menu on track, choose tires and change to the other compound with the arrow keys
