Heated Steering Wheel
I also have a BMW and there is a separate switch on the steering column to activate the steering wheel heat.
Because of the stalk's location, it's actually easier to see how it works if you look at it while standing next to the car with the door open. When I'm in the driver's seat, I have to go by feel, which is easy as long as you already know how it works.
To turn it back off just twist it back the other direction (towards you).
