How to Open the Sunroof on a BMW X3
1. Insert the key into the X3's ignition and turn it to 'Position 2,' which is labeled on the switch.
2. Locate the sunroof switch on the center console, above the rear-view mirror. It is the second switch from the left.
3. Press the switch to raise the roof and the sliding visor slightly. Press the switch twice to raise the sunroof more. To open the sunroof completely, press the switch twice in the opposite direction.
