Have you gotten it to work prior? The toggle can be confusing.
First try the on/button off (see picture at the bottom of this post) ... it's the easiest way
The toggle (see picture at the bottom of this post) switches it between the massage (top diagram on infotainment screen) and adjusting the lumbar (middle diagram on infotainment screen) and seat bolsters (bottom diagram on infotainment screen).
You then need to push on the outer part of the disc (just under toggle) up/down/left/right (you can feel the raised arrows) to turn massage on/off (I think that's up/down) or adjust the 'Roll' 1-3 (I think that's side to side) ...or to adjust the lumbar or seat bolsters.
I didn't notice the on/off button until like 2 months after I got the car! (
Blue is toggle,
Red is direct on/off button)
