Very simple. Start the car. Make sure the shade is closed. Push and hold the moon roof button straight up and don not let go (as if you were attempting to vent). The process will take about 1 full minute. Again, DO NOT LET GO of the button until process is complete. After 15 seconds or so, the process will begin: shade will slide back; moon roof will open and close vent; moon roof will slide completely open and then completely close; shade will slide close. HOLD THE BUTTON for this entire process and a couple of seconds after the end of the process.
